Embedded parts are metal elements used in various structures. Products of this type have a wide range of applications, but most often they are used in construction, especially at the stage of installation of reinforced concrete structures. The production of embedded parts is carried out using high-strength steel grades.

Where such details are applied

Without them, it is impossible to build a number of structures, both monolithic and precast concrete. Embedded parts are used in the construction of administrative buildings, workshops for industrial enterprises and similar civilian buildings. They are used when working with stadiums and agricultural facilities.

Embedded elements are used in the following types of work:

• creation and installation of facade elements;
• assembly of elevator wells;
• construction of enclosing structures;
• creation of concrete and reinforced concrete products.

Embedded parts manufacturing process

We carry out the production of metal embedded parts using high-tech processes: laser cutting, welding, threading, etc. For additional protection against corrosion, we use galvanizing, powder painting and other processing methods.

The technology for the manufacture of embedded parts makes it possible to obtain fixtures of almost any size and shape.

Constructions mortgage type are subdivided into 2 groups.

• Closed. Anchors on both sides are hidden by plates. The purpose of the closed elements is the construction of supports, floors and facades.
• Open. Anchors are closed with one plate. This option is suitable for the installation of different types of equipment and structures: climatic technology, metal stairs, ventilation systems, and much more.

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

This increases the overall strength, simplifies the construction 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 in such a way 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, the embedded elements increase the strength of the prefabricated structure, help to 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 required 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 for such products:

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

installation of fencing, 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 facilities, including reservoirs, technical reservoirs.

Assortment of embedded parts

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

Embedded elements can be open as well as 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 fastener.

To provide embedded parts with a longer service life and additional corrosion resistance, manufacturers use a variety of coatings, such as galvanized.

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

It is important to buy embedded parts when it is necessary to reliably connect several concrete products or concrete products 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 you to associate other structural elements with them. Welding of embedded parts is usually used to implement this stage.

Most extensively, this type of materials is used in construction conditions in which it is necessary reliable connection several components of the design:

• 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 on the basis metal structures;
• frames from a profile;
• other.

Ultimately, the field of manufacturing embedded parts has unlimited potential, since the areas of use of products only expand over time. In part, 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 increase 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 reinforcing 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 assembly and construction works wide profile. Buying embedded parts of the second type is relevant 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, they are calculated with a safety margin suitable materials... Further, the manufacture 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 with dimensions (length, section) and bearing capacity corresponding to the project are selected. 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, most often they use a 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 to installation works;
• deviations that may be in the batch.

Requirements of norms

In accordance with the norms state standard comprehensive control of embedded parts GOST 14098-91 in production is carried out. 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 standards. The edges must 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, should not be 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 of 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.

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.

In compliance with all safety requirements, it 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 the customer's 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 marking.

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 securely 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 with the help of embedded parts:

• various structures (bearing 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.
