Overlapping structures - reinforced concrete runs

Running ferro-concrete play a big role in the construction. These elements are necessary and indispensable in the construction of large buildings. For today, no construction site can do without them. The compactness of the ceilings makes it possible to use them in hard-to-reach places, which greatly accelerates the construction process and significantly reduces labor intensity. There is a strict form of manufacturing runs. These structures are manufactured in full accordance with the GOST standards and drawings of various series. The total weight of the product may vary. It all depends on the weight of the reinforcement used in the manufacture, as well as the width and height of the floor. Ferroconcrete overpasses are highly technical due to the fact that they are durable, fireproof and durable.

Product Description

The run itself is a long beam that has a rectangular or T-section. Mixing of steel reinforcement and concrete gives such a building material as reinforced concrete, and it is from it that the floors are made. Runs of reinforced concrete, a series of which 1.225-2, make the construction structure more durable and, accordingly, reliable. Such elements are used in the construction of public buildings of brick. Running reinforced concrete is used as a horizontal overlapping aperture. There are two types of such elements. The first of these is an overlap having an unstressed reinforcement. The second, on the contrary, with a tight reinforced structure. They are classified by the brand of concrete, which was used in the manufacture.

Classification and marking of floors

The marking of such building elements denotes the type of construction and determines the bearing capacity. Runs ferro-concrete (GOST 26992-86) are in demand at erection of bearing walls and overlappings. They are very convenient in the construction of the roof structure. Bypassing all communications, they are easy to place and secure in accordance with the calculations.

Types of structures

Runs ferro-concrete are of two types: solid and latticed. Each of them has advantages and disadvantages. For example, when carrying out work to cover the roof, the weight of the run is important. In this case, products of the lattice type are uniquely used. An important factor is the life of the run, a high level of moisture resistance, frost resistance, reliability and strength. Products made of reinforced concrete are time-tested. Such runs have long and successfully been used in the construction of buildings. To date, their profitability is very high. A large percentage of builders use it as their main supporting element. This building material of artificial origin is able to withstand a static and dynamic load. Its strength with time only increases, so its use in construction is simply necessary. Good characteristics define reinforced concrete runs as an excellent material that can be used in the process of large-scale buildings.
