Since we have touched on the topic of profile hardening, we will immediately explain what it is and why. Hardening of the profile is carried out exclusively at the factory and in accordance with GOST. For aluminum profiles used in hinged facades, two degrees of hardening are used: T6 and T66. T66 is better.

Hardening is necessary for aluminum, everyone knows that it is a soft material. Despite the fact that the profiles are called aluminum, this is very conditional, according to the main element contained in the alloy. Of course, this is an alloy of metals, otherwise aluminum profiles could not be used under load. To enhance the ability of the profile to withstand bending and compression loads, atmospheric influences, it is hardened. To harden means to grow old. The profile is artificially aged by firing to make it more durable.

Production and types of profile

To give the aluminum alloy the plasticity necessary for the production of a profile, in addition to manganese, a number of other components are added. Aluminum facades are finished with hinged panels. They can be over three meters long. Locks are made immediately. During deformation, the sheet is passed through a series of rolls, which gradually change the shape of the profile. The number of transitions is calculated.

1. Aluminum profile for facades can be made in different sizes on the same conveyor
2. This changes the tool - rolls, for deformation and the color of the coating material
3. Lamination and spraying are carried out in a hot way immediately after deformation
4. Then cut to length

Aluminum facade systems

Aluminum facade systems are assembled from several types of frame profiles. Its production is different from the creation of cladding panels for a building. This is mainly U-shaped rental for racks and L-shaped brackets.

Large rolls of aluminum sheet are also used for it:

• the thickness of the sheet is greater than on the panel;
• before producing the desired configuration, the bay is cut to length, strips are made;
• their width is equal to the perimeter of the profile, which is made using deformation.

Hinged aluminum facade systems

Perforated and L-shaped profiles for strengthening individual sections of the wall and corners are indispensable when creating wet facades and leveling building walls for hinged aluminum facade systems. It is used to make edges for various flat surfaces and countertops. The frame profile has a rectangular or square shape in cross section. It is used to create door frames, furniture frames, tables and nightstands for the kitchen, suspension system guides. Along one side, the O-shaped contour is not closed, and a canvas or glass is inserted into the groove, then fixed in the frame with the help of gaskets and seals.

Features of aluminum T-profile for facades

Based on the name, it is clear that the T-profile has a T-shaped section. The standard size of this profile is 60*80*1.8mm. Modifications are possible, of which two should be distinguished:

It happens that the profile is made of the same dimensions, but of greater thickness 60 * 80 * 2.1 mm. The increased thickness is justified when using heavy cladding, this does not apply to the composite, it is light. Therefore, as a rule, a profile with a thickness of 2.1 mm is used for heavy facings - terracotta, natural stone. When the weight of facings exceeds 30 kg/m2.

The profile thickness of 2.2 mm and above is due to the use of AD-31 aluminum alloy. Alloy AD-31 has been approved for use in ventilated facades since 2014. It is cheaper than the standard 6060 or 6063 alloy, but contains an increased amount of alloying elements. Alloying elements are metal impurities. Consequently, the AD-31 alloy is more susceptible to corrosion and turns yellow over time.

6063(6060) alloy profile and 1.8mm thickness is better or same as AD-31 alloy profile and 2.2mm thickness.

Why is this happening? The defining characteristic of the profile is its rigidity. Rigidity depends on the alloy, the degree of hardening, the branching of the section and its thickness, and each indicator affects to a different extent. In order not to bother with the study of all the nuances, just compare similar profiles from different manufacturers in terms of moment of inertia along the x-axis and along the y-axis. The higher these indicators, the greater the load the profile can withstand.

The section of the profiles may differ when used for different claddings. Profile for smooth width 80mm. The profile for the composite can be of completely different configurations: it can be a standard T-shaped (when using an alluvial sled) or a Y-shaped (with an internal sled). Profiles for facing with terracotta panels of some brands may have holes for fixing the clamp directly into the profile. Such holes reduce the bearing capacity of the profiles, but they have a place to be applied. You can't tell the cross section of each profile. But you can always request an Album of Technical Solutions for a curtain wall system from the manufacturer. The album of standard solutions contains a comprehensive overview of all the possibilities of the system.

How to cut aluminum profile

It all depends on the volume of the profile cut. Locally, you can get by with a grinder. Although the grinder has an abrasive disc and is not intended for cutting aluminum. Aluminum metal is viscous, and the disc can fly out during operation, which is very dangerous. A disc for aluminum is needed with teeth, as for cutting wood.

If by the nature of your activity you often have to deal with this type of work, then you need professional equipment. Professional equipment for profile bending is, for example, a cutting machine with an aluminum disc. Sometimes the machine is called a "miter saw". It is sold in ordinary hardware stores specializing in the sale of tools.

Dimensions of aluminum profiles

Structural aluminum profile

Aluminum profiles for windows and other glass structures can be of any design and size. However, for example, an aluminum machine profile 45 45 mm or 50 x 25 mm are the most common options according to the corresponding GOST 22233-2001. They are used as a frame for the construction of various partitions.

And the aluminum corner profile is 20x20 mm. This 20x20 aluminum profile is the most popular and is used to protect the outer corners of plasterboard partitions and cladding from technical breakdowns. And also for interior work.

In addition, there are also corners in the following sizes: 10 x 10 mm, 12 x 12 mm, 15 x 15 mm, 20 x 10 mm, 25 x 25 mm, 30 x 15 mm, 30 x 20 mm, 30 x 30 mm, 35 x 10 mm, 35 x 35 mm, 40 x 20 mm, 40 x 40 mm, 50 x 20 mm, 50 x 25 mm, 50 x 30 mm, 50 x 50 mm, 60 x 40 mm, 60 x 50 mm, 60 x 60 mm, 70 x 70 mm, 80 x 40 mm, 100 x 50 mm, 100 x 100 mm, 120 x 40 mm.

Curved aluminum profiles

Such aluminum profiles, especially in sizes: 25 x 25 mm, 30 x 30 mm and 50 x 50 mm, are used for the installation of office partitions, in the manufacture of furniture sets, the construction of various structures, the decoration of exhibition halls, the production of doors and windows, for cladding and household goals.

There is a universal aluminum profile 8 mm. In another way, such a profile is also called finishing. It is used for joining panels, glass shelves, ceramic floor tiles in PVC floors, edging, delimiting surfaces. And also along the edges of the flooring and with combined coatings.

Hardened aluminum profile Aged aluminum profile Hollow aluminum profiles

How to connect an aluminum profile

Two aluminum profile whips can be connected to each other to increase the length to the required length. It is possible to use such an extension only if the load in this area is small. This decision must be confirmed by a static load calculation.

It is always necessary to connect the profile in a fixed, rigid way. Manufacturers of the ventilated facade system have such an element in the "Connecting piece" design. It is usually used to connect the lower and upper cantilevers of the profiles in order to give the structure more rigidity. At the same time, on one profile, the connecting part is attached to oval holes in order to provide the possibility of expanding the profile.

In the case of a profile extension to increase the length, this connecting element must be fixed in both cases, i.e. into round holes.

Overview of reliable manufacturers

For windows, it is recommended to use products of well-known companies or brands that have been verified by friends and have a fairly long lifespan. For example, a domestic organization for the production of anodized aluminum products has been growing in the market for about 20 years.

Choosing a cheap design for a window, you can get a short-lived material that will rust on the outside, and the seal and fittings will have to be changed regularly.

One of the leaders in the production of aluminum profiles is REHAU. The company has been on the market since 1948 and offers a wide range of aluminum and plastic windows.

Another brand is Schuco. Its products are reliable, and the profiles of this manufacturer are distinguished by excellent external characteristics - an elegant design that can decorate a room.

Aluminum systems are offered by Profilco. Features of these profiles for windows: dust, wind protection, sound insulation, as well as providing protection against penetration. Window blocks made of aluminum of another brand - Raynaers stands out from a number of analogues due to the guarantee of safety. Similar designs for windows are used in banks, administrative and military facilities.

Another well-known and reliable company is Providal. Specializes in the manufacture of cold-type aluminum windows. Compared to PVC analogues, aluminum structures have a number of advantages:

• due to the low weight of such profiles, windows of almost any size can be made, which will not contribute to the weighting of the walls;
• security from outside penetration;
• protection from external factors (dust, noise, wind);
• long service life.

It should be noted also more attractive appearance thanks to the possibility of coloring. An anodized aluminum profile (Rosla company) is offered on the market.

Price category and comparison with analogues

Today, the most popular are two types of window blocks: aluminum, metal-plastic (PVC). High-quality plastic windows are reinforced, the metal layer is located inside the profile and is not visible.

Unscrupulous manufacturers offer PVC windows without reinforcement, which is easy to check with a magnet. The cost of such windows will be low, as well as the degree of their reliability.

Accordingly, it is necessary to compare metal-plastic products and aluminum counterparts. A cold profile will cost less than a warm one. A coated product will be more expensive, in particular, an anodized profile (Rosla). The minimum cost of 1 sq. m of cold-type aluminum structures is 3,000 rubles. (stained-glass window) or 6,000 (window block).

Warm windows are several thousand more expensive. Metal-plastic analogues will cost much cheaper (from 2,500 rubles). But such products of well-known brands offering high-quality products, in any case, will be quite expensive.

Aluminum U-profile

The U-shaped profile is a standard in the technology of a hinged ventilated facade. Such a profile is not subject to torsion, is reliable, but, unfortunately, it is expensive. Therefore, in Lately it is practically not used; instead, modifications of T-shaped profiles are used. It is necessary to distinguish between a rectangular profile in the system of classical fastening (along the wall) and interfloor fastening.

Interfloor profile rectangular section more powerful than the profile in the classical system. The interfloor profile is fastened in two places, as a rule, above and below. Such a node falls on the interfloor overlap, so the system is called "interfloor". The interfloor fastening system does not imply a support node, i.e. are not used in it. Therefore, the profile must have a high moment of inertia. The interfloor profile is always much more powerful than the classic one. Its price starts from 600 rubles / rm. m.

On the market, there is an alternative to using a square profile as an interfloor section - an “I-beam” section. The development made it possible to reduce the weight of aluminum by 15% per linear meter. m. Therefore, such a profile is more profitable in price.

Aluminum profile product to save time and money

To achieve any goal, it is necessary to choose high-quality materials. If we are talking about the construction or manufacture of some devices, then the quality characteristics are doubly important. Today, rolled metal is used almost everywhere, which has excellent technical and operational properties. You can buy an aluminum profile today relatively inexpensively, while the part will last for decades, retaining its original appearance. Why choose aluminum parts? First, this perfect ratio prices and quality. Secondly, it is impossible to find products that would have the full range of properties that silver metal does. Profile systems are time-tested, so they are not afraid of moisture, temperature changes, or any other natural factors.

Key Features and Benefits

There are several good reasons why profiles are made from this rolled metal. It is worth noting that the metal is several times lighter than iron, while it is not subject to corrosion. The price of an aluminum profile is much lower compared to other types of rolled metal. It is only slightly inferior to other products in terms of electrical conductivity. In modern construction, profile systems are popular due to the plasticity of the material: it can be rolled into foil, the thickness of which will not exceed 3 mm.

From a weighty list of advantages, the following parameters can be distinguished:

Ease of processing, thanks to which it is possible to produce products of any shape and size.

• Ease of operation.
• Reliability, so the designs stand for decades.
• High resistance to negative environmental factors.
• Parts can be used in quite extreme conditions, because they are not afraid of corrosion, temperature changes, or direct sunlight.
• The material can be painted, thanks to which it acquires an aesthetic appeal. By the way, there are about two hundred shades available for coloring.

Types of window profile

Designs of this type have recently become unusually popular. Meanwhile, the Krasnodar and Stavropol regions until recently were almost the only regions where windows were used on such material as aluminum profiles. All types of profiles (in St. Petersburg, Moscow and other cities of the Russian Federation - you can see similar designs everywhere today) are distinguished by an aesthetic modern appearance, which basically determined their demand. Therefore, the engineers developed the "warm" material of this group. Now such structures are used not only in the south and in the European part of the country, but also in the Urals, and even in Siberia.

An unusual design is what distinguishes the aluminum window profile. The configurations of these products can vary considerably. In the manufacture of window profiles, not only the actual bent aluminum tape is used, but also many additional elements that improve the operational properties of windows. These include fittings, seals, as well as various linings and inserts.

An aluminum profile for balconies is classified, the types of which can be different, mainly according to the following criteria:

• The type of seal used. The latter can be average or narthex.
• Type of hardware fastening (on screws or terminals).
• The number of thermal chambers. The value of this parameter can range from 3 to 7.
• type of thermostat. The chambers between the insulating inserts of such profiles can be filled with either foam or rigid material with a low degree of thermal conductivity. Rigid aggregates are usually made of polymers: dederon, propylene, capron, nylon. Inserts can also differ in thickness (20-34 mm).

Light weight, aesthetic modern appearance, strength and durability - these are the main advantages that characterize the aluminum profile. All types of profiles in St. Petersburg, Krasnodar, Yekaterinburg and other cities of the country enjoy well-deserved popularity. It is simply impossible to imagine many sectors of the economy, and even more so such an area as construction and repair, without this easy-to-use material today.

Benefits and areas of use

The popularity of aluminum profiles with a T-slot is due to its undeniable advantages, such as:

• resistance to high humidity, temperature extremes and mechanical stress;
• strength of connection with other elements;
• simple installation;
• versatility of application;
• good price;
• anti-corrosion properties;
• structural rigidity;
• light weight.

The positive properties that the T-profile has allow it to be used in the construction industry as a base that reduces pressure on the structure and joints for various panels. It is also in demand at enterprises where windows and furniture are made. In addition, aluminum alloy T-profile is used in machinery and shipbuilding.

In our company, you can buy a T-shaped profile with different coatings at retail or wholesale. We work with legal and individuals on favorable terms for both parties. Here you can find the necessary varieties of aluminum products and buy profiles with delivery in Moscow and anywhere in Russia.

Advantages of aluminum over other metals

What we habitually call just aluminum, in fact, alloys that have a different composition. For the production of aircraft, copper is the main alloying component. For the production of rolled products - profiles for building facades and furniture, manganese is added.

Among other metals, aluminum differs:

• lightness - low specific gravity;
• resistance to moisture and many acids;
• strength;
• electrical conductivity;
• high heat transfer;
• low thermal conductivity.

Aluminum profile

Externally, the aluminum profile has a matte silver color. It is easily polished and bonded to a variety of finishes, from sprayed to laminated. Therefore, aluminum facades always look original and elegant. Scratches are covered instantly with a film of aluminum oxide with high hardness and strength. It does not react with moisture and reliably protects the bulk of the metal

This is especially important for the kitchen and bathroom. Durable alloy edge protects edges and corners

Glass and other canvas are securely fixed in the frame.

Kitchens with aluminum profile facades

Characteristics of facades made of aluminum profiles and panels

Aluminum facades have a warranty period of more than 50 years. Aluminum panels are coated in various ways. They can replicate the texture of many materials, from plaster and stone to polished and lacquered mirror surfaces.
Facades made of aluminum are unique. The variety of sizes and colors allows you to create an infinite number of options for finishing the building. Windows and inserts in an aluminum frame can be of any shape.
Panels and plates protect the walls of the house from cold and dampness. Hanging systems and siding allow the walls to breathe. They move the dew point outward. The steam is expelled from the room. The frame profile allows you to make reliable and beautiful aluminum facades with glazing.
Light metal edge securely holds large double-glazed windows. The combination of matte silver metal surface and shiny glass create a great contrast and make the building elegant. Additional finishes can be wood effect panels or lacquered aluminum L-profile edges.

Ventilated facade

Aluminum windows main types of aluminum windows

When aluminum windows are made, systems of warm and cold profiles are used. A feature of warm aluminum systems is the presence of a thermal bridge.

The main purpose of a thermal bridge is thermal insulation. Thermal insulation is achieved by pressing polyamide strips on each other into the inner and outer parts of the window profile. Aluminum profiles are intended not only for the production of windows, but they also allow the production of large-scale structures (balconies, loggias and other facade structures). Basically, the assembly of window systems consists in connecting (type - mechanical) corners by pressing them with corner cotter pins or crackers.

Glazing of loggias and balconies is the most familiar and technologically advanced way of glazing. Significant corrosion resistance, strength and lightness are all the most essential properties of aluminum, which is usually used for glazing loggias and balconies, and is constantly exposed to negative influence external environment.

When glazing balconies or loggias, it is better to use aluminum sliding windows, because they satisfy the individual requirements of any customer, even the most demanding one. Sizes and shapes of aluminum windows are completely unlimited, neither in size nor in shape - everything basically depends on your personal choice. To make it easier to decide on the choice of windows, here are the main types of aluminum windows.

Aluminum windows are:

• Deaf (glazed window when there is no need to open this window).
• Opening. They are subdivided in turn into: folding (open from above); opening the window to the outside; tilt-and-turn (windows open in different directions); pivoting (windows open only in one direction). Combined view (the window as a whole or its parts combine several various ways discoveries).

The production of aluminum windows mainly consists in extrusion of profiles, which are then coated with special paints. Such production makes aluminum window frames durable enough. It is also possible (if desired) to decorate frames from other materials.

An anchor is essentially a fastener that resembles an anchor in shape, for example, a steel connection laid in stone walls; there are anchor bolts, anchor ties in joints with guaranteed tightness, etc.

The fastener is mated with the base array not directly, but through an anchor or dowel, which create necessary moment clutch. Strictly speaking, it is difficult to draw a clear distinction between an anchor and a dowel. In our opinion, an anchor is an element that in a certain (mechanical or chemical) way increases the adhesion between the main fastener and the base to the required level. In fact, the dowel is a lighter version of the anchor.

There are driven, wedge, rod, embedded (anchor bolts) and chemical anchors.

wedge anchor

It is used for fastening heavy structures, cable routes, load-bearing consoles, railings, etc. by through installation to solid concrete, natural building stone, solid brick.

This is a steel rod with a cylindrical movable sleeve in the form of a belt, a tapered shank and a nut. Does not require precise drilling depth and hole cleaning.

When the nut is tightened, the coupling creeps onto the shank, and bursting occurs, which securely holds the structure in the carrier base.

Rod anchor

Essentially a wedge anchor, but designed to be installed deep through several successive layers of cladding and insulation. An additional advantage of such a product is the ability to install it at an angle.

Drop anchor

It is used for critical installation (at heavy loads), for fastening heavy structures, cable routes, consoles, gates, etc. to solid concrete, natural building stone, solid brick.

The driving anchor is a hollow cylinder. On one side there is an internal thread, on the other side there is a spacer zone of four segments. To ensure controlled wedging, a core (cone) is located inside the hollow cylinder.

When the anchor is hammered, the segments burst in the drilled hole. This prevents twisting and secures the anchor securely. When the bolt is screwed in, additional expansion and fixation occurs.

Mortgage anchor or anchor bolt.

It is used for fastening heavy structures, cable routes, load-bearing consoles, railings, etc. by through installation to solid concrete, natural building stone, solid brick. Can be used for fastening to thin concrete partitions.

The anchor bolt at the end can be with a nut, ring, hook or head, and depending on the use case, one or another type of this anchor is used.

When screwing the bolt, the cone-shaped nut is drawn into the coupling and bursting occurs. Moreover, the fastening goes along the entire sleeve due to its additional deformation at the base of the anchor.

Such a fastener should be loaded after the concrete has completely hardened.

The recommended working load on the anchors should not exceed 25% of the maximum (pull-out load). The load indicators are given for concrete with a strength of 200-250 kgf / cm2. The recommended load increases in proportion to the increase in concrete strength. When installing anchors in cracked concrete, the pull-out loads must be multiplied by a factor of 0.6.

chemical anchor

Above, we considered anchors operating on a mechanical principle. A chemical anchor is a glass ampoule with an adhesive (polyester resin) combined with a chemical pin.

It is used for mounting suspended ceilings, as well as for fixing various materials under water. Good resistance to aggressive environments. Among the advantages can also be attributed to the small size of the hole relative to the stud. If necessary, two ampoules can be used in series, which increases the depth and reliability of fastening.

After preparing the hole, an ampoule is installed in it, which should then be drilled with a pin. For the adhesive to harden, some time must pass, during which the anchor should not be loaded. The duration of hardening depends on the ambient temperature and can range from 10 minutes at a temperature of more than 20 degrees to 5 hours at a temperature of minus 5 degrees.

For use on vertical surfaces only, not suitable for use on ceilings.

In construction and installation work The most demanded operation must be considered the connection of various kinds of elements, both among themselves, and fastening to fixed bases, namely: walls, floor, ceiling, beams, etc. For these purposes, various types of fasteners are used, however, in some specific cases, anchoring will be the best option.

If you open specialized sites and look at the photo of the anchor bolt, you can note a wide range of designs, sizes and other distinctive features. What is the principle of secure fastening? What is an anchor? - read about all this in this article.

Design features

In its most general form, an anchor must be understood as a special fastener installed in a bearing, fixed base and designed to hold some structure or part.

Such a connection is of a collapsible type. In other words: if necessary, the structure fixed by means of an anchor can be dismantled, and then installed again without changing the fastener itself.

If we trace the etymology of the name, then the word anchor has German roots and is translated as "anchor", which fully describes the principle of its operation.

Structurally, anchor bolts look like a special kind of stud, which is laid in a blind or through hole, and under certain conditions, it is clamped in it, moreover, one property is true for mechanical anchors - the stronger the load on the stud, the stronger it will be held in the hole. In some variants, a bolt and a specially shaped nut may be used, but the principle remains the same.

Chemical

A special capsule with an adhesive solution is placed in the hole. During installation, the capsule is destroyed and after hardening, securely fixes the pin in the hole.

The main advantage is the possibility of installation in hollow bases.

Mechanical anchors

This is the most common and practical type. In this case, the principle of operation of anchor bolts is based on the effect of wedging or collet unclamping in a steel sleeve.

Depending on the weight and the degree of force applied to the structure to be installed, the required dimensions of the anchor bolts are selected. For mechanical fasteners, installation technology, base features and other external factors are taken into account. In this context, the following types are distinguished, distinguished by the method of implementing the principle embedded in the idea of ​​\u200b\u200bfastening.

wedge anchor

Represents a special wedge nut that is installed inside the hole, with a sleeve installed on top. When tightening the bolt, the nut, trying to get out, wedges the sleeve and is firmly held inside the hole.

This design is a sleeve with a conical hole inside and threaded. When the anchor is screwed in, the sleeve is wedged in the hole and is thus fixed.

Expandable anchor "butterfly". The main feature is that it can be installed in through holes, as well as in the case of thin-walled bases. The principle of operation is based on the deformation of the middle part and the opening of the petals when the anchor is screwed in.

Expanding anchors. This is the most common type and does not require particularly careful observance of hole sizes. The principle of operation is based on the expansion of the sleeve when a stud with a cone-shaped or spherical thickening at the end is pulled out of it in the process of screwing the nut onto it and pulling it out.

So, we have indicated the main types of anchors used in practice. In some specific situations, special fasteners are required, according to the underlying principles of operation, it is similar to those considered, but has design features, and therefore below, as an example, two of its varieties are presented.

Special anchors

Anchor bolt with a ring - in this case, there is a special ring at the end of the anchor, a cable, twine or various kinds of extensions are threaded through it. It is used for mounting and strengthening of spacer cables when installing masts, columns, banners, as well as in other special situations.

Another variety is anchor bolts with a hook. Their scope is similar to the previous one, the whole feature is the ability to put on rings, i.e., there is no need to thread the cables through the hole.

Anchor bolt mounting technology

First of all, depending on the thickness of the base and the mass of the structure to be strengthened, the size and length of the anchor fasteners are selected.

Drill a hole in the base. The bushing must fit snugly. The depth is made slightly greater than the length of the sleeve.

Attention! After drilling is done, carefully clean the hole from the remnants of the base, crumbs, etc.

An anchor is installed in the hole, after which the structure is assembled. Installation must be done with light hammer blows. The force applied during twisting should gradually increase. Do not "overdo it": the anchor must hold firmly, but not destroy the base material.

Photos of anchors

What is an anchor, types of anchors.

Is it worth nailing something to a concrete wall? Or are there any more effective ways of fastening? These and other questions will be answered by this article, which tells about the actual fasteners - anchors, let's figure out what an anchor is and what types of anchors are. The range of anchors on the market is represented by an innumerable variety of different modifications, for example:

• wedge anchor KA;
• drop-in anchor LAH;
• rod anchor RU;
• rod-shaped anchor TA;
• screw anchor RA;
• embedded anchor SORMAT, DRIVA;
• brass anchor MSA;
• anchors MTA, KVTM, PFG, OLA, and so on.

When carrying out finishing, repair, or construction work, it is impossible to do without fasteners. These can be screws or nails, that is, devices that themselves, without any additional parts, are able to fasten materials and withstand the corresponding load. They can be applied to drywall sheets, wood, or thin elements made of metal, the fixation that occurs between these simple fasteners and the base is enough to effectively secure and perceive the loads that fall on this structure.

However, if the base is made of stone, concrete or brick and has a greater (compared to light materials) hardness, then the use of such an attachment will not be able to solve the problems that arise. In order to be convinced of this, it is enough just to try to drive a nail into a concrete wall, and the validity of this statement will immediately become clear.

Anker translates from German language, as an “anchor”, and this name fully explains the principle of its functioning. The fastener is not fastened to the main array directly, but using dowels or anchors, which are created in order to create the desired moment of adhesion.

The conclusion is that it is extremely difficult to make a specific separation between the dowel and the anchor.

We have the opinion that a dowel or anchor is a part that in some way (chemically or mechanically) increases the bond between the main product to be attached and the base. To the level at which these elements are able to transfer the load placed on them. In general, the dowel is a lighter version of the anchor.

Main types of anchors

The scope of anchors during construction work is the fastening of heavy structures. When carrying out, anchoring is mainly used when fixing window and door frames, when attaching suspended ceilings, and also when installing chandeliers and lamps. Now it is clear what an anchor is. Let's move on to the types and places of application with photo examples.

Drive-in anchors brass, steel

Drive-in anchors LA, LAH. This is the simplest type of anchoring that has an internal thread. Used for installation in stone, brick or concrete structures. It is inserted into a pre-drilled hole of the desired diameter and depth. The hole for this type of anchor (as for all others) must be pre-cleaned. After the anchor is inserted into the hole, it is unclenched with a special device, with the help of which the desired degree of adhesion is achieved. Following this, a fastener suitable for the thread is screwed into the anchor. This type also includes the MTA anchor, which is used for bases with internal cavities.

Wedge anchors with nut

Wedge anchors KA. They are made using different technologies and are electro-galvanized KA, acid-resistant KAH, and hot-dip galvanized KAK. Equipped with a special blade, which expands during installation and is fixed in the hole. Allows through fastening through the material mounted on the base. It is inserted into the prepared hole, driven in with a hammer and tightened with an ordinary wrench. Products of this type include screw anchors RAR-stainless, or RA-electrozinc. These types of anchors are equipped with a recessed head screw. This allows them to be used when fastening door and window frames. In the process of tightening the screw, the anchor blade is securely fixed in the mounting hole.

The RU rod fixator works on the wedge anchor principle and is designed to be installed through several cladding and insulating layers. An additional quality of such products is the ability to install it at a slight angle to the surface. The expanding wedge locking method is also used in the construction of the TA rod anchor. This product, equipped with an internal thread, complete with a shaft that can be cut to the required length if necessary, can be used to attach several layers of materials. After hammering the anchor into the mounting hole, the fixed element is fixed on the rod using a washer and nut.

PFG anchors are internally threaded and, as inserts are screwed into them, they expand and effectively lock into place. The PFG anchor can be used in combination with an IR insertion bolt, an AK hook head bolt, a VR conical bolt, an SR eyebolt or an IHH, IH insertion sleeve. This anchor fastening is used for carrying out works with the firm bases.

The structural basis for this type of anchor is concrete, stone or. The brass sleeve of this MSA anchor has a conical (threaded) internal cavity that gradually tapers towards the tip. With the help of this constriction, in the process of tightening the screw, the sleeve expands and is tightly fixed with its uneven walls inside the mounting hole made in the base.

Anchor is a fastener that combines the design features of a bolt and a dowel. It is used for fixing into stone, brick, concrete and other hard and porous materials. The use of anchors makes it possible to achieve high fastening strength, which significantly exceeds the capabilities of a dowel or screw.

Classification of anchors by size

The name anchor is translated from German as "anchor". Indeed, this fastener provides a secure fixation. It is used when you need to fix the horizontal bar or other sports equipment on the wall. It is used in the installation of air conditioners, for fixing balcony elements to the facade, for fixing plumbing, etc. Anchor bolts can withstand a large dynamic load, vibration and other mechanical stress.

These fasteners are divided into groups according to size:

• Small - diameter up to 8 mm, and length up to 55 mm.
• Medium - diameter up to 12 mm with a length of up to 120 mm.
• Large - reach a thickness of 24 mm and a length of up to 220 mm.

In construction, the choice of anchors depends on the requirements of GOST. For certain purposes, clear parameters of the fasteners to be used are established.

Classic anchor designs

The design of the anchor bolt may differ in the method of installation, as well as the connection of various elements to them. The most popular varieties of this fastener are the following designs:

• Spacers.
• Drop-in.
• Wedge.

Spacers

Expansion anchors are the most common design. It is a bolt or stud, the nose of which is made in the form of a cone. A sleeve with a longitudinal section is put on this rod. Since its inner diameter is smaller than the cone on the nose, it cannot come off the hairpin. A special nut on the top of the anchor protruding from the wall, when screwed, drags a stud onto itself, which cannot pass through the sleeve and unclenches it. As a result, the latter is deformed, adhering tightly to the walls of the hole and holding the entire anchor fastener as a whole.

Spacer fasteners provide effective fixation only in those materials that have a dense internal structure. It is primarily concrete. If such anchors are mounted in hollow materials, then special strength cannot be achieved.

The expansion anchor comes with:

• Gadget.
• Crochet.
• Ring.
• Double spacer.
• Hex head.

Nut Anchors They are a stud that is pressed with a regular nut. It uses a long sleeve, which provides a large contact area inside the hole. The peculiarity of using such an anchor is not only that a certain structure can be pressed against the wall with a nut, but it also makes it possible to screw another nut onto its stud. It can be an eye nut or a special welded tip of any shape.

Anchors with ring or hook are almost identical in design as with the nut. They use a stud, at the end of which a mounting ring or hook is provided. The deformation sleeve itself has a dense top with a knurled thread. When the pin is unscrewed, the sleeve expands, because it has longitudinal through slots that make the central part more plastic. This fastener is used in cases where it is necessary to hook a cord, cable or rope. It can also be used to connect the chain to the wall. In everyday life, they are usually used to securely hang a chandelier from the ceiling. Also, children's swings in apartments are attached to them.

Double-spaced anchors have a special design. The main difference between this fastener is that when unscrewing the stud, one spacer sleeve enters the second. The expansion is carried out close to the end of the anchor, which is especially important if it is necessary to fix it in a porous material. Due to the fact that the fasteners are fixed in the depth of the wall, the maximum possible fixation is ensured.

Anchor with hexagon head represents almost the same design as with the nut. The only difference is that instead of a stud and nut, it uses a regular bolt. When twisting, the cone at the end begins to drag the sleeve to the bolt head, simultaneously crushing its walls. As a result, it tightly compresses the sleeve and deforms it until the hole dimensions are completely filled. This design can be designed for a wrench, as well as additionally for a screwdriver. Such anchors are rarely made large, and usually their diameter does not exceed 12 mm.

Wedge

Wedge anchors are a long metal stud, at the end of which there is a deformation sleeve. When screwing the pin, the small petals expand. This happens in the depth of the wall far from the front part, therefore cracking of the material is excluded.

driven

A driven anchor bolt is fundamentally different from other designs. To ensure its disclosure, it is necessary to first plant the sleeve itself, and only then screw in the pin. In order to use such fasteners, it is necessary to prepare a hole, and then put the anchor sleeve into it. After that, a pin is applied to the installed sleeve, which must be hit with a hammer. This allows you to deform the sleeve and press it tightly against the walls of the hole. Next, the pin is removed and the bolt is screwed, to which the fixation is carried out.

Chemical anchors

Chemical, or adhesive, anchors are very reliable fasteners that provide a strong hold. This fastener is a set of ordinary studs and glue. To use such fasteners, a hole is drilled, which is cleaned of dust and subsequently filled with adhesive. After that, a hairpin is inserted into it and left to solidify. The disadvantage of such fasteners is that it takes a long time to gain maximum strength. In the case of conventional anchors, fasteners can be used immediately.

Chemical fasteners are used in cases where you need to fix in a soft or porous material that cannot withstand a large load. In order to achieve the highest possible holding force for the stud, it is necessary to properly prepare the hole. First, the drill deepens to the required distance, after which a cone-shaped void is sampled in a circular motion. It is necessary to make sure that the bottom of the hole is much wider than its neck. This will allow more glue to be poured in. After hardening, it will not only hold the stud by sticking to the walls, but it will also physically not be able to break out of the hole, due to the narrow exit.

How to use a regular anchor correctly

In order for the anchor to work to its fullest, it is necessary to carry out its correct installation. First of all, you need to choose the one that will correspond to the diameter of the anchor. It is not necessary that it be a fraction of a millimeter thicker, since when drilling , or , the resulting hole will always be slightly larger, due to the rattling of the tool in the hands. It is worth controlling the depth so as not to overdo it, as this will reduce the performance of the fastener. Next, be sure to blow the hole to remove crumbs and dust from it. This can be done with a cylinder of compressed air, or in extreme cases with a syringe. Only then can the anchor be inserted and tightened.

Some builders, to increase the reliability of fasteners when working with porous materials, prefer the additional use of adhesives. In particular, liquid nails are used. A small amount of mass is squeezed into the hole, after which an anchor bolt is driven into it. In fact, after tightening the spacer, a rigid fixation is provided not only with ribs, but also with glue.

Usually, when installing the anchor, it is quite difficult to drive it into the prepared hole. If there are no problems with this, then the hole turned out to be excessively thick and you cannot count on a reliable connection. If this happens, then you will have to choose a thicker anchor.

In order to drive the fastener into the prepared hole, it can be hammered using. In this case, you need to use a soft lining. If fasteners with a hook or ring at the end are fixed, then you can beat directly. In the case when the tops of the anchor are threaded connection, then blows can damage him. It is necessary to combine the tip of the stud and the side of the nut at the same level. After that, a wooden block is applied, and blows are made with a hammer. As soon as the fastener comes to the end, you can tighten it with.

How to pull out an anchor bolt

The connection received by the anchor is very reliable, but there are times when the need for it ends. In this case, it is necessary to remove the fastener from the wall. This is quite difficult, but quite doable. To work, you need a wrench, as well as a hammer and. First you need to unscrew the pin so that it no longer bursts the sleeve. This procedure differs depending on the anchor design. In some cases, you can simply tighten the bolt, while in others, loosen the nut and use a hammer to drive the stud deep into the hole.

After the sleeve is released, it can be pulled out. In most cases, pliers will not be able to catch on it, so you will need to destroy a little wall around the hole in which the anchor is planted. To do this, a chisel is substituted near the anchor sleeve, and a groove is made about 1 cm deep. After that, it will be possible to catch on the sleeve with pliers and pull it out.
