Purpose of embedded parts. What are embedded parts, and where are they used? Embedded parts come in two different types

At the stage of pouring reinforced concrete structures, most of them require an embedded part, recessed entirely or partially into concrete. These elements are used to join (welding, threaded connections) individual parts of the prefabricated foundation or attach it to it flights of stairs, wall panels, floors, and other enclosing structures.

Why are mortgages needed?

The foundations are made of concrete; it is very difficult to dock and connect two such products. Therefore, the embedded part is immersed in the concrete, leaving a thread, plate, and other seat on the surface. It is enough to weld these elements to each other to obtain complex spatial structures made of reinforced concrete. Mortgages are used for construction:

Almost the entire assortment of rolled metal products (circle, sheet, reinforcement, strip, channel, angle, rod) is used for the manufacture of embedded parts.

Classification of embedded elements

To increase strength concrete structures reinforced with meshes of wire, rods of periodic and constant cross-section. These elements also apply to embedded parts closed type. Classification is made according to the following criteria:

Any embedded part must comply with GOST 10922-90, since they bear a significant load. For the foundation, an anchor rod or reinforcement A-III - A-II class 25 - 8 mm in diameter is used. If the temperature in the operating region drops below 30 degrees, choose plates made from VSt3ps6 steel. In other cases, VSt3kp2 steel is used.

Anti-corrosion treatment consists of galvanization, galvanizing, painting. For light loads, stamped parts are usually placed in reinforced concrete products. When shearing and tearing forces increase, anchor rods welded to the plates are used.

Embedded manufacturing technology

When designing metal elements inside the foundation, it is necessary to take into account the following nuances:

The stamped type embedded part is manufactured in accordance with the RS9903 album, developed by leading reinforced concrete designers: NIIZhB, MNIITEP. The sketches given in the album allow you to use ready-made diagrams minimum possible reinforcement in the area where the building is located.

The design should include the minimum possible sections of rolled profiles and reinforcement. To do this, part of the effort is distributed to stops made of strip steel or short rods.

Welded joints

To increase the adhesion of stamped parts inside concrete parts The foundation at the ends of the strips is created by 6 cm hooks with two or more ledges. The rods are connected to the plates, rolled profiles by welding in accordance with the requirements of GOST 19292:

• T-weld - manual or automatic submerged arc welding (in some cases zigzag, relief surfacing), roller welds, contact-relief, semi-automatic in carbon dioxide
• inclined seam (joint) - submerged straight or at the end
• overlap joint - an extended seam, along two or one relief (manual arc, contact, respectively)

Relief spot welding is prohibited for welding joints used in concrete products that experience vibration loads during operation (for example, flights of stairs).

Installation locations, use of embedded elements

The main operations of building a foundation and other enclosing structures are:

For individual developers, the industry produces a range of embedded elements for monolithic foundations. The simplest modification of an anchor for fastening wooden stand has the design:

Mortgages for attaching gates and gates to fence posts are made independently:

• plate – used for hanging sections, wicket hinges
• corner - connects the plate with profile pipe pole armored belt

Homemade embedded elements are usually not calculated, are made from scrap materials, and are immersed in concrete without connection with the reinforced belt of the structures. Most often, an individual developer uses mortgages in the following operations:

For more serious reinforced concrete structures and buildings, it is necessary to purchase factory-made products with embedded parts. All of them undergo flaw detection, laboratory tests for permissible loads, have accompanying documentation, and manufacturer’s warranties.

Embedded parts are metal elements that are placed into buildings and structures before concreting begins. As a result, they act as screeds or connecting elements, ensuring the integrity and reliability of the resulting structure.

Classification of embedded parts

Embedded parts come in two different types:

• open;
• closed.

These elements can also be classified according to the principle of placement of anchor parts in relation to the flat element.

Based on this feature, embedded parts with inclined, perpendicular, mixed or parallel position of the rods are distinguished. Separately, elements are distinguished whose rods have threads.

Embedded parts are made from different types of steel:

• channel and angle,
• strip and round.

These elements are used during the installation of various structures and buildings.

Their main function is to connect the most important structural elements. Typically, use is planned in advance, and only then are they installed by welding or bolting.

Using embedded parts

There are various types of embedded parts hardware, installed in a monolithic metal frame structure. It is thanks to them that the building acquires a framework of reinforcing mesh, channels and beams, as a result of which it becomes more stable and durable.

Thus, the main areas of use of embedded parts are repair and construction work. Metal elements are usually manufactured according to standard forms (standard designations on the drawings: ZD-1, ZD-2, MS-1, MS-2, MN-1, MN-2), but customer requirements are taken into account, and, accordingly, sizes and shapes details may vary.

Manufacturing of anchor bolts

Embedded parts are often represented by anchor bolts. They are often used for laying in reinforced concrete foundations in order to subsequently secure various equipment or equipment to the foundation.

The production of anchor bolts is carried out in accordance with state requirements, set out in GOST 24379.1-80 (for models with thread diameter M12-M140). If the parts are planned to be used in northern regions with a cold climate, they are made from frost-resistant steel 09G2S.

Sometimes the project indicates the need to use a foundation bolt, which is made from steel type 08G2S. In this case, only the pin is machined from the specified material, and the remaining elements are made from St3-St20 (in accordance with the requirements of GOST 24379.1-80).

At your request, after bolt production, additional procedures can be carried out, for example, hot or cold galvanizing.

Another popular type of embedded parts is anchor foundation blocks. These elements are foundation bolts (according to GOST 24379.1-80), which are connected to each other using grade metal.

It is especially important that the center distances are maintained correctly.

The foundation blocks also include similar ones:

• bolts,
• corners,
• hairpins,
• circle,
• fittings,
• sheet,
• stripe,
• profile pipes.

Where are embedded parts used?

As noted above, embedded parts are widely used in construction, since they serve as a frame that increases the strength of the entire building. In addition, such parts are used when installing lamp posts.

Parts of such a frame can be tightly connected to each other, or fixed with bolts. In accordance with this, their fastening can be open or closed. Also, all metal parts are usually treated with a special coating to increase service life.

Where to buy?

You can purchase embedded parts in the quantity you need on the website of the St. Petersburg Severozapad plant. The catalog contains a large number of ready-made products, among which you can easily choose what you need.

Modern construction cannot be imagined without the use of embedded parts. These seemingly simple structural elements are indispensable in the construction of residential buildings, shopping and office centers, sports facilities, public buildings and workshops of industrial enterprises.

The secret of the popularity of embedded parts in construction is that they are able to provide maximum reliable connection metal structures among themselves or firmly connect reinforced concrete products with building elements made of metal, technological equipment, pipelines and other hanging elements that require rigid fastening great strength due to upcoming serious weight or other loads.

What are embedded parts?

This is a metal plate and reinforcement or anchor(s), fastened together by a welded joint. The plate can have a wide variety of thicknesses, since state and industry standards, the provisions of which apply to the production of metal structures of this group, allow the use of sheet metal with a thickness of 2 to 200 millimeters for their production.

A
reinforcement and anchors can also have the most different diameter. In addition, they are sometimes cut or rolled with a thread, which turns an ordinary embedded part into an adjustable component that significantly simplifies installation work during the construction of buildings and structures and reduces construction time.

So why did embedded parts get such a name? The fact is that a metal plate can be placed into a concrete or reinforced concrete product at the stage of its production, and the reinforcement remaining on the surface will allow the slab, flight of stairs or other structure to be securely fastened by welding.

In the same way, using embedded parts, various building elements made of other non-metallic materials are installed.

How embedded parts are made

The process of producing embedded parts can be quite complex, despite the apparent simplicity of the product itself. First you need to select high-quality sheet metal of the required thickness, and then cut it.

Plates of embedded parts can be made in the form:

• square,
• rectangle,
• trapezoids,
• rhombus

The required shape is obtained by cutting a metal sheet (for products with a large plate area, technology is used laser cutting and high-tech equipment). Next, the workpiece goes through the edge processing stage and is welded with anchors. After all the components of the product are connected into a single whole, the embedded parts are primed and covered with a layer of protective material, that is, galvanizing or painting is performed.

Such treatment prevents corrosion from damaging areas of the product that remain open after completion. installation work, which significantly extends its service life. Latest transactions technological process manufacturing of these metal structures are marking the product according to its specifications and packaging.

Places for installing embedded parts

These products are used literally everywhere where a reliable connection of building and technological structures made of metal with reinforced concrete products is necessary.

Let's give sample list operations in which it is recommended to use embedded parts:

1. installation of columns;
2. fastening aluminum profiles;
3. fastening of facades;
4. fastening of heat exchangers, containers and technological equipment;
5. installation of floodlight masts, cell towers;
6. fire escapes and reinforced concrete flights of stairs;

Table 1. Operating conditions for embedded parts

During installation various systems pipelines and various connections are used by builders embedded part. In order to produce embedded parts in Tula, various steels are used. The production of such parts involves the use of sheet and strip steel, as well as reinforcement. These products can come in a wide variety of shapes. The embedded part is a necessary element in monolithic construction.

Types of embedded parts.

1. Open embedded part
This type of product is covered with a plate on only one side. This design is necessary for production purposes.
2. Closed embedded part

When making a closed embedded part, two closing plates are used.
In any case, embedded parts must have increased strength and resistance to corrosion. For the latter purpose, each part during production is coated with a special composition - galvanization. Embedded parts with this coating long time can withstand external factors.

The installation method may vary. Parts can be welded or embedded in a reinforced concrete structure.

The designation MH indicates that such products are metal and cannot be removed.

Embedded parts play a very important role in construction. These products determine how durable the finished structure will be.

On construction market products are supplied ready-made. It is also possible to make these parts to order. Modern production assumes the possibility of using customer drawings for such purposes.

At correct installation can be guaranteed long terms operation of this product. The quality of the product also depends on the class of steel from which it was made embedded part.
