Embedded parts as essential elements of modern construction. What are embedded parts and where are they used? What are embedded parts in construction

One of the most important stages in the construction of any building is the installation of embedded parts. This procedure precedes the start of concreting and further ensures the integrity and stability of the structure.

Compliance with all safety requirements is of particular importance, since it is they who perform the functions of connecting elements for the building.

Features of the manufacture of embedded parts

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

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

If necessary, these elements can be made according to your drawings and individual 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 be 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 performed for their manufacture:

• reinforcing and metal bending,
• cutting (for example, plasma) metal,
• knurling and threading,
• primer,
• welding,
• edge processing.

The final steps are corrosion inhibitor coating and specification labeling.

What are embedded parts for?

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

Also embedded parts are used when fastening:

• various reactors,
• telephone masts,
• crane runways.

They are used to install:

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

Installation is carried out using embedded parts:

• various structures (supporting and enclosing),
• louvered and metal grilles,
• hydraulic structures, etc.

What are the embedded parts?

Usually the production of embedded parts is carried out of two types:

• closed,
• open.

You can also choose the most suitable shape for you: the elements differ according to the ratio of the anchor bolts to the metal plate.

Then they can be divided into parts with a bar arrangement:

• oblique,
• mixed,
• perpendicular,
• parallel.

Elements with a thread 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.

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

It is important to buy embedded parts when it is necessary to reliably connect several concrete goods or concrete goods with metal systems. This method has a positive effect on the reliability of the structure, simplifies the installation work.

The installation of the embedded part of GOST 14098-91 is carried out in such a way that the plate is concreted, and the anchoring components protrude beyond the structure. These sections of reinforcement will allow other structural elements to be connected to them. Welding of embedded parts is usually used to implement this stage.

Most extensively, this type of material is used in construction conditions, in which a reliable connection of several structural components is necessary:

• installation of block systems like canals, wells and tunnels;
• arrangement of durable enclosing systems;
• creation of columns, facades, construction of multi-storey buildings or, for example, cell towers;
• hydraulic structures;
• equipping door and window openings;
• bases based on metal structures;
• frames from a profile;
• others.

Ultimately, the sphere of manufacturing embedded parts has unlimited potential, since the areas of use of products only expand over time. Partly, the point is that the prices of embedded parts are more profitable than traditional methods of achieving similar functions in the design.

If it is necessary to improve the protective characteristics, the finished products can be additionally processed for corrosion protection, for example. Galvanizing and painting are common, but this increases the price of embedded parts.

Types and manufacturing

The production of embedded parts involves the creation of several basic product variants. There are many types according to the shape of the finished product, but all of them can be divided into several groups depending on the location of the anchoring components:

• perpendicularly located reinforcement segments;
• their inclined arrangement;
• mixed look.

You can buy embedded parts with a square, rectangular, round, diamond-shaped base. Improvement of the adhesion characteristics with the hardened composition is achieved by the applied threads on the surface of the rods.

According to the standard, the manufacture of embedded parts GOST 14098-91 allows you to create two types of materials: open with one plate and closed with plates on both sides of the anchors. The first ones are more flexible functionally, therefore they are suitable for installation and construction works of a wide profile. Buying embedded parts of the second type is important mainly for the construction of buildings.

Method of making embedded parts

The production of embedded parts is not very difficult, traditional processing methods are used to start the process, such as cutting and welding of embedded parts.

Initially, the load at which the structure will operate is calculated. Based on the data obtained and the specifics of the application, suitable materials are calculated with a safety margin. Further, the production of embedded parts in the amount required for the implementation of the project begins. A sheet of metal of the required thickness is dismantled into blanks, rolled products are selected with dimensions (length, section) and bearing capacity corresponding to the project. Components are welded to the site at specified angles. At the final stage, the finished materials are painted or coated with zinc to increase corrosion resistance.

The production of embedded parts is in full compliance with state standards, compliance with the standards helps to achieve high strength characteristics. The calculations take into account the dimensions of the finished structure, loads and the possibility of equipping the entire system with additional elements. Separately, in the manufacture of embedded parts, possible loads in the transverse and longitudinal directions are taken into account, as well as deviations that are difficult to avoid when installing components.

As a result, a variety of materials are obtained, which can be the simplest parts with one anchor, that is, a platform with a single reinforcing bar. The most complex shapes of products require the presence of many rods, welded at certain angles. It is worth emphasizing that the prices of embedded parts also depend on the specific features of the structures. However, the most often used system for calculating the weight of finished materials.

Most of the embedded parts are made individually for each project. A label is attached to the products with marks about the requirements:

• brand;
• the number of elements in the batch;
• date of manufacture;
• technological control mark on acceptance;
• requirements for installation work;
• deviations that may be in the party.

Norm requirements

In accordance with the norms of the state standard, a comprehensive control of embedded parts GOST 14098-91 is carried out during production. Thanks to this approach, it is possible to achieve the highest quality of the finished product.

So, the angles between the anchoring components and the platform must comply with GOST 14098-91. The edges need to be cleaned of slag and sagging formed during the high-temperature cutting process. The surface of the materials should be free from contamination in the form of oil stains and others, in addition, the presence of foci of rust and scale, which flake off, are not allowed. Welding points of embedded parts should not be cracked. The transition from the welded part to the base should not have undercuts, and all craters must be welded when making embedded parts. It is forbidden to leave slag and sagging on the deposited layer, structural elements should not be burnt. Uncooked areas, arson of the base and fistulas are prohibited.

It is possible to buy embedded parts of GOST 14098-91 with certain discrepancies regarding the dimensions included in the project:

• the position of the flat components can vary by up to 10 mm;
• ease of installation in some projects requires a deviation in the arrangement of structural elements on the site - the permissible parameter is 100 mm;
• the axes of the profiled hollow elements can deviate up to 10 mm;
• face components should not differ from flatness by more than 5 mm.

The plant of reinforcement products and structures "ARMIKON" offers high quality materials for construction projects. The prices of the embedded parts will be optimal, and all the deadlines are met, therefore it is really profitable to cooperate with us!

Recently, the term "embedded parts" is found more and more often. In general terms, such a part is a metal plate with a reinforcement (anchor) welded to it. The options for plates, as well as fittings, can be very diverse.

Why is this needed and where are they laid?

Embedded parts allow to ensure reliable connection of reinforced concrete structures (RC), as well as RC and metal structures. And this, in turn, significantly increases the overall reliability of a building or structure, simplifies installation and leads to other positive effects.

The parts are laid in the concrete structure (usually at the production stage of the latter, but not necessarily). Moreover, this is done in such a way that the metal plate is in the concrete, and the anchor comes out. Thanks to this anchor, ZhBK can be reliably connected to another reinforced concrete structure or to a metal frame element. In most cases, the anchors are connected by welding.

Hence, it is obvious that embedded parts increase the strength of prefabricated structures, make it possible to rigidly fix certain elements and, in general, significantly increase the reliability of the object. This is probably why modern monolithic construction is unthinkable without them.

Where are embedded parts used?

Wherever it is necessary to connect two or more elements of reinforced concrete structures or metal structures. Among the most obvious areas of application, we note:

• Installation of block structures such as wells, canals and tunnels;
• Installation of load-bearing or enclosing structures based on reinforced concrete structures;
• Installation of columns;
• Installation of external facades;
• Installation of bases for masts, cell towers and other high-rise structures;
• Hydraulic structures, including technical reservoirs and reservoirs;
• Arrangement of window and doorways;
• Creation of foundations for buildings based on metal frames;
• Installation of frames from a metal profile.

This is far from a complete list, but it should already be clear from it that modern construction involves the active use of embedded parts.

What are the options for embedded parts?

As you already understood, the general construction is quite simple - plate and anchor. However, the plate can be made from different alloys, have different thicknesses and shapes. The number and type of anchors can also vary over a fairly wide range - it can be round or profile reinforcement of various diameters. In some cases, the anchor can be threaded, which makes it possible to adjust the connection.

In addition, embedded parts are of open or closed type. In the first case, there is only one plate, in the second - there is a plate on both sides of the anchor.

To give the parts additional properties, they can have various coatings, for example, galvanized. This improves corrosion resistance and extends service life.

The technology for the production of embedded parts does not imply any particular complexity:

• A metal sheet of the required thickness is cut into plates of the desired shape;
• The required amount of reinforcement of a given type and length is welded to the plate;
• The finished part undergoes additional processing (galvanizing, painting, etc.).

When installing various piping systems and various connections, builders use embedded part... In order to make embedded parts in Tula, various steels are used. The production of such parts involves the use of sheet steel, strip steel, and reinforcement. These products can be of a wide variety of shapes. Embedded part is a necessary element in monolithic construction.

Varieties of embedded parts.

1. Opened 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 manufacturing a closed embedded part, two cover plates are used.
In any case, the embedded parts must have increased strength and corrosion resistance. For the latter purpose, each part is coated with a special compound during production - galvanized. With such a coating, embedded parts can withstand external factors for a long time.

The installation method can be different. Parts can be welded by welding or embedded in a reinforced concrete structure.

MN designation indicates that such products are metal and non-removable.

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

Products are supplied to the construction market in finished form. It is also possible to make these parts to order. Modern production assumes the ability to use customer drawings for such purposes.

Correct installation can guarantee long service life of this product. Product quality also depends on the grade of steel from which it was made embedded part.
