The value of the regulatory acts and classifications in industrial production is very high, especially at the intersection of construction and metallurgy.

schedule of reinforcement

Assortment of rebar is a breakdown of the most used hot-rolled and cold-drawn steel rods or composite materials, which are represented in a certain state range of metallurgical and other industrial enterprises. The assortment is usually made according to current regulatory and technical documentation that defines the gradation and optimum performance of the rod cross section. It is designed for the rational analysis of reinforcement on strength characteristics and waste minimization during construction and installation works. This is due to the fact that even carbon steel of ordinary quality St3, ST5 – quite expensive, and overrun invalid.

Origin of the term and especially its applications

schedule of reinforcement

The Term "schedule of reinforcement" is common only in the professional community of engineers, technologists and other technical employees of the construction sector and industrial enterprises-producers of this constructive material. It is maloupotrebimym in wide use. Its origin the expression obligation borrowing of the French word assortiment, which in the course of adaptation to the Russian language has acquired specific features, inherent only to phrases used in a professional environment.

Key features and differences between products ' range

assortment of valves GOST 5781 82

The Structure of all assortments can be divided into the dimension and profile, in the first embodiment indicate the basic layout of one kind of rebar with detailing its features, while in the second option classification wires are the purpose of their application (welded, hardened valves and so on). Classic of the Russian Federation assortment of rebar (GOST 5781-82 its source) combines all the above signs and displays the metrics in the most convenient form. In this state the standard deals with the principles of steel reinforcement (wire and rod) specified requirements, defines the allowable deviation of material loss. In comparison with the conventional ideal of the assortment, which would contain the entire numerical collection of sections of various profile and length of the bars, in the Guest displayed only rationally selected sizes. They do not allow as undue stress on structural elements because of the excess cross-sections and their own weight, and considerable excess consumption of materials and provide only minimal irrecoverable losses during the technological processes of construction. At the same time, various industrial enterprises can produce products according to they have developed the same technical conditions, taking into account its purpose. First of all it concerns rod and wire products made of composite materials and corresponding recommendations application.

Features of the use of rebar and grades in high rise construction

Despite the fact that the scope of the steel reinforcement is not wide enough (unlike other products metallurgy), in construction of reinforced concrete monolithic structures, it is practically indispensable. Because this kind of construction of multi-storey and high-rise buildings involves the arrangement of a solid knitted or welded frame and its embedment. It takes all the critical values of the stresses in structures: tension, compression, bending, wind fluctuations, and if required, seismic effects, also prevent impermissible disclosures of cracks in reinforced concrete building elements. Such an important element of any structure comes to the construction site in coils or in bundles withterminals (depending on the diameter of the rebar), each of which has its own marking. At the place of discharge of material is it, a covering document for which you are overhead of the manufacturer or supplier of that specified range of the valve.

The importance of the regulation of products in the field of metallurgy and construction

Industrial complexes for the production of concrete products that produce construction with steel embedded parts, using the methods of steaming and vibrating, sell their products to companies constructing buildings from prefabricated concrete elements. The operation of manufacturers and contractors working in this sphere is impossible without sufficient items of steel materials, and the basis for their production and the assortment of rebar. In the field of regulation, standardization and unification of such products of such technical documentation assumes the role of a unifying factor, which is a normal interaction between noncontiguous areas of manufacturing.
