Reinforced concrete jumpers are called rectangular reinforced parallelepipeds, which are acute necessity during the construction of openings in the house. All reinforced concrete jumpers are usually divided into two main groups. That is, there are bruskery jumper, which indicate PB and pile jumpers, respectively, PP.
Typically, a slab reinforced concrete jumper consists of a large number of block jumpers. It turns out that PP is a kind of block for some reinforced concrete jumpers PB. One of the most important parameters is precisely the calculation of the reinforced concrete jumper for the load. It is on this, which load on reinforced concrete jumpers depend on some dimensions along with the length of unlocking the jumpers into the masonry.
If we translate us the language of builders, then the jumpers may well be called supporting, that is, jumpers that have a really large load. The term itself is like brick, door and window belong to GOST. It is for this reason that reinforced concrete jumpers differ in accordance with the size, and therefore excess weight.
Furniture rings for wells are a real part of a whole system that can be blocked or open a small opening of people at one time. Only in this case, the total gravity of the floor will be able to be transmitted to the walls right in front of the project. In the event that there is no large load, then there should be about two meters to carry out a large continuous opening. Use the jumper of the supporting or ordinary ordinary. Be sure to remember that modern well rings are not able to limit themselves to use only during the construction of sewage. In addition, there are also wells of various purposes, that is, sewer, drainage, network and gas pipeline. Completely different types of wells mean the use of various types of concrete rings. Almost all rings usually have their own standard diameter. The height of everyone is standard, that is, equal to 90 cm. All well rings can differ in the design of the end ring. As for the locks for disorders of the functioning of wells caused by the transverse displacement of the soil, the rings should in no case violate the displacement of the transversely displaced soil.
