Over the past few years, in almost every area of ​​construction there has been an wide application embedded parts. By appearance Such products look like metal plates to which reinforcement is welded (experts call it an anchor). There are several variants of parts available for sale, designed for specific purposes. Without them, modern construction is impossible.

Such components are used to increase the reliability and strength of reinforced concrete and metal structures. Thanks to their use, the level of reliability and durability of the house and other structures increases, and their installation is simplified.
As a rule, products are laid during the manufacturing process of reinforced concrete structures. True, in certain cases The filling is also done after the production of reinforced concrete products (welding is used). The elements are laid in such a way that the metal plate penetrates into concrete mixture, and the anchor reinforcement remained from its outer part. It is because of the anchor located outside that a strong connection to another slab or to a metal structure is ensured.

Where is this metal product most often used?

Embedded parts are used where it is necessary to securely combine reinforced concrete structures or metal structures. Most often they are used for the following purposes:
for installation of structures made of reinforced concrete blocks (these include wells, tunnels, channels);

• during the installation of columns;
• during the construction of foundations on which metal frames will be installed;
• for installation of fences and load-bearing structures, for the construction of which reinforced concrete structures are used;
• when installing facades outside buildings;
• in the process of installing bases for operator towers mobile communications and other similar structures;
• during the construction of hydraulic structures.

Of course, this list of areas for using embedded parts is not complete, since in modern construction The scope of their application is growing every year.

Types of embedded parts

Despite the fact that embedded parts have very simple design, consist only of a metal plate and an anchor; there are several types of products on sale. First of all, they differ in the types of alloys that are used to create the plate, as well as its shape and thickness.
Anchors vary in shape, diameter, and the presence or absence of threads. Threaded fittings allow you to adjust the connection between reinforced concrete and metal structures. Also on sale are products with one and two platins, to which a reinforcing anchor is welded.
The production of embedded parts involves the following operations:

• sheets of high-quality metal are cut into several plates of a certain shape;
• reinforcement pre-cut to the required length and shape is welded to them;
• on finished product apply galvanized coating, paint and perform other work related to additional processing of the part.

Thanks to this manufacturing technology, durable, reliable, high-quality embedded parts are obtained that are not afraid of negative impact metal oxidation.

Embedded parts are elements for built-in additional equipment and some elements of the water circulation system, the placement of which is planned at the stage of design and construction of the pool bowl. If you do not initially provide for the presence of embedded parts, then their installation in the future will be very problematic. To choose the right embedded parts, you need to decide on the type of pool and its finish.

Stationary pools are divided into concrete, composite and polypropylene.
Concrete pools can get off mosaic/tiles or special film, which acts as waterproofing. The design of the embedded parts depends on the type of pool and type of finish. For concrete pools finished with tiles or mosaics, embedded parts “under concrete” are used, or as they are also called “under mosaics/tiles”.
In composite, polypropylene and concrete pools finished with film, embedded parts “under the film” are used; they are also called universal because if necessary, such an embedded part can be placed in a concrete pool with mosaic decoration. Structurally embedded parts for film are distinguished by the presence of a pressure flange and sealing gaskets, which provide sealing of the connection.

Material of manufacture

Based on the type of manufacturing material, embedded parts are divided into ABS plastic, stainless steel and bronze.

Plastic mortgages the cheapest, least strong and durable, can crack during unqualified installation or in the cold. Products made from ABS look less aesthetically pleasing and over time lose their original color under the influence of UV radiation and chemicals used to disinfect water. Plastic mortgages can be sleeved or non-sleeved. IN unsheltered mortgages the pressure flange is attracted by a self-tapping screw, which goes into the “body” of the mortgage. If installed unskilled or re-installed, this connection may not hold up and if you overdo it, the mortgage may burst. Also, damage to the unit can occur after a few years, when the plastic becomes more fragile. Sleeved mortgages allow you to avoid this problem and ensure greater reliability of the fastening unit due to the presence of metal sleeves with threads in the body of the embed. The flange is fastened to such embedded parts using M5 screws rather than self-tapping screws. It is much more difficult to damage this connection; in addition, it can be assembled and disassembled without any fear.

Stainless steel embedded parts more expensive, much stronger and more durable than plastic mortgages, insensitive to temperature changes, which is important for outdoor pools, and do not lose their aesthetic appearance over time. Mortgages are made of two grades of stainless steel. Brand AISI304 used in fresh water swimming pools. If the pool is supposed to have an electrolyzer or sea ​​water, then it is recommended to use parts with AISI316 brand because this steel is more resistant to aggressive environments.

Bronze embedded parts belong to luxury class equipment. They are distinguished by the longest service life, high anti-corrosion resistance, resistance to mechanical stress and are suitable for any water, including sea water. A swimming pool with bronze mortgages speaks of wealth, opportunities and respectability of the client. The only disadvantages include the high cost.

All stainless steel and bronze embedded parts require grounding to prevent galvanic corrosion of metal due to “stray” currents.
When choosing the material for making embedded parts, you should remember that they are poured into concrete, and it is impossible to replace them in the future without spoiling the finish of the pool. The cost of embedded parts compared to the total cost of the pool is small, and it’s not worth saving on this, so We recommend paying attention to stainless steel embedded parts. If in the case of a concrete pool finished with mosaics this is not so critical due to the lack of flanges and seals, then in a pool finished with film, a composite or polypropylene pool, it is strongly recommended to use stainless steel embedded parts, or, in extreme cases, plastic lined products.
The initial higher cost of products made of stainless steel or bronze turns into a benefit during the further operation of the pool, because replacing these elements is very problematic.

Types of embedded parts

Embedded parts are divided into hydraulic parts and embedded parts for amusement rides.
Hydraulic embedded parts call the elements with the help of which water is recirculated in the pool. They are divided into two groups - intake devices and water supply devices into the pool. Hydraulic embedded parts include such elements as skimmers, nozzles, bottom drains, passage pipes, water level regulators and overflow grilles.

TO embedded parts for amusement rides include: plateaus and nozzles for air massage, hydromassage nozzles, water intakes, pneumatic buttons, lighting fixtures, underwater speakers and built-in counterflows.

It is recommended to think carefully required quantity mortgages and their location. When planning and placing the embedded parts of the pool, it is better to turn to specialists, because it is not difficult to install the elements incorrectly on your own, but it is much more difficult to redo them so that everything is correct. Correct installation embedded parts are the key to stable operation of additional equipment and the water circulation system. Professional installation of embedded parts will be a condition for the uninterrupted operation of additional equipment and the water supply system.

One of the most important stages during the construction of any building - installation of embedded parts. This procedure precedes the start of concreting and subsequently ensures the integrity and stability of the structure.

In compliance with all safety requirements, it has special meaning, since they are the ones who perform the functions of connecting elements for the building.

Features of manufacturing embedded parts

Most often, elements to be placed into a structure before concreting have standard shapes and sizes. That is why the production of embedded parts is carried out on the basis standard projects and drawings. One of the requirements for a construction project is a list of metal structures used and their specific names.

For a more accurate understanding of customer requirements, embedded parts have symbols:

If necessary, these elements can be manufactured according to your drawings and custom sizes, but the cost of such products will be higher.

The production of embedded parts is carried out from metal sheets. Depending on the specific element, the thickness of the material can range from 2 to 200 mm. Anchor bolts are made from special reinforcement and rods.

In order for the parts to ensure the integrity of the entire building, the following work must be carried out for their manufacture:

• reinforcement and metal bending,
• cutting (for example, plasma) of metal,
• knurling and thread cutting,
• primer,
• welding,
• edge processing.

The final stages are coating with an anti-corrosion compound and marking according to specifications.

Why are embedded parts needed?

The production of embedded parts today uses in great demand, since these elements are necessary in the construction of various buildings and structures. For example, they will help to reliably install heat exchangers or containers, aluminum profiles or facades.

Also, embedded parts are used for fastening:

• various reactors,
• telephone mast,
• crane tracks.

They are used to install:

• technological equipment,
• fire and embedded ladders,
• searchlight masts,
• columns and fences.

Using embedded parts, installation is carried out:

• various structures (load-bearing and enclosing),
• louvered and metal grilles,
• hydraulic structures, etc.

What types of embedded parts are there?

Typically, the production of embedded parts is carried out in two types:

• closed,
• open.

You can also choose the form that suits you most: the elements differ according to their relationship anchor bolts to the metal plate.

Then they can be divided into parts with the location of the rod:

• inclined,
• mixed,
• perpendicular,
• parallel.

Elements with threads on the rod belong to a separate class.

Material for the production of embedded parts

Another basis for classification is the material from which the parts are made.

Most often these are different types of steel:

• channel,
• round,
• strip,
• corner

To ensure that builders install the parts correctly, their location is indicated immediately on the drawing. Then the workers will only have to fasten them with bolts or welding.

The North-Western Plant is engaged in the production of embedded parts.

Embedded parts have become widely used in construction, in particular during the installation of reinforced concrete structures (prefabricated and precast-monolithic types). In addition to the reinforcing and connecting function, these elements also impart strength and solidity to the joints. The manufacture of embedded parts is carried out using high-strength steel grades. The main areas of their application are the construction of hangars and bridges, the construction of concrete, stone and reinforced concrete structures, the installation and fastening of facade elements, the assembly of elevator wells, the construction of enclosing structures and various repair and restoration work.

Device

Most embedded elements are a steel plate to which anchor rods, straight or curved, are welded. A stamped steel plate without rods is also an embedded part. In addition, embedded elements include anchor rods of perpendicular, parallel, inclined and mixed types. There are embedded parts of open and closed type, and the latter are used only during the construction of buildings. During the manufacture of a reinforced concrete structure, before direct pouring of concrete, the specified element is usually placed in a special form. To ensure higher strength of the part, assembly adhesive can be used.

Materials

The priority steel grades for their production are 3PS/SP and 09G2S. It can be round, strip, channel, or angle steel, although in most cases, of course, sheet steel is used. As for anchor rods, they are mainly produced from A-II and A-III class steel. The size of such a rod varies depending on the specific design. If there is a risk that embedded parts will succumb to negative natural influences, they are protected by applying a primer or other special coating to the exposed parts. Treatment with an anti-corrosion compound will give these elements durability and prevent the rusting process. To do necessary calculations and choose the right embedded element, use the formulas building codes and rules (SNiP).

Product selection

In order to select a product, the following factors should be taken into account: the location of installation of the part, the calculation of the indicator of the working conditions of concrete, the load indicators that are distributed over mortgage device etc. Embedded parts usually have the following markings: MS, MD, MN, ZD. In order to impart stability and solidity to structures, as well as to provide strong mechanical connections at installation locations, it is necessary to select these elements with maximum accuracy and correctness. In addition, for reinforced concrete structures it is necessary to pre-specify the geometry of the embedded devices, since these structures are usually supplied with designated connecting dimensions.

The term "embedded elements" is increasingly found in everyday life. Small metal plates, connected by welding to an anchor or reinforcement, help to firmly connect reinforced concrete structures between themselves, to ensure high-quality fastening of reinforced concrete structures with metal parts.

This increases overall strength and simplifies the creation of the structure. Most often, the laying of parts is carried out during the manufacture of reinforced concrete structures. In this case, the element is positioned so that the plate is in the concrete, and the reinforcement or anchor remains outside. It is thanks to the presence of the fastening element that an excellent connection between reinforced concrete structures is achieved, which is often carried out by welding. Thus, embedded elements enhance the strength of the prefabricated structure, help rigidly fix its individual parts, and significantly increase the reliability and durability of the structure.

Areas of use of embedded elements

The main area of ​​application of embedded parts is monolithic construction. Moreover, any structure in which it is necessary to connect reinforced concrete structures with each other, as well as with metal components, is unthinkable without the use of embedded elements. Here are the main areas of application of such products:

construction of block structures such as canals, wells, tunnels;

installation of enclosing and load-bearing structures based on reinforced concrete products;

creation of external facades;

construction of foundations for the construction of buildings based on metal frames;

installation of hydraulic engineering facilities, including reservoirs and technical reservoirs.

Assortment of embedded parts

All embedded elements have two components - a plate and a fastening element. However, the plates can be made of different alloys and vary in metal thickness and configuration. The type and number of anchors can also vary quite widely. Fastening element can be made from round as well as profile reinforcement different sections. In some cases, the anchor can be equipped with a thread that allows you to adjust the connection.

Embedded elements can be open or closed. The first option assumes the presence of one plate and one anchor. In the second case, two plates are located at both ends of the fastening element.

To provide embedded parts with a longer service life and additional corrosion resistance, manufacturers use various coverings, for example, galvanizing.

The technology for manufacturing embedded elements can be quite complex, despite the external simplicity of the product. To produce such products, high-quality rolled metal of a given thickness is selected. Cutting is done in accordance with the shape of the plate, which can be a rhombus, trapezoid, rectangle or square. After this, the edges of the products are carefully processed and the fasteners are welded. Finished parts are primed, painted or galvanized.
