How is a reinforced monolithic slab plate made?

In any multi-storey building it will not be possible to do withoutfloor slabs between floors. Most of them are reinforced, as this kind of products have increased strength. Although in the same way today blocks for stairs, as well as door and window lintels are made. So how is the reinforcement of the monolithic slab plate carried out?

First of all, you have to calculate correctlyall indicators for performing such an operation. First, it is strongly recommended that only reinforcing elements of class A3 be used for this purpose. Their diameter varies between 8-14 mm and depends on the designed load on the building.

As a rule, reinforcement of a monolithic plateoverlap is made in two layers. Simply put, the reinforcement is located at the top and bottom of the plate. Note that the concrete layer over the reinforcing metal must be no less than 20 mm. If there are no ready-made nets, the elements are joined with a special knitting wire.

Attention!

For this purpose, welding is unacceptable!

All elements must be applied in a continuous layer,overlap is not allowed. Only in case of lack of length it is possible to increase it with the help of tie rods, but at the same time their diameter is 40 times greater than that for the reinforcement used by you. So, if a grid with a rod diameter of 10 mm was used in the plate, then the connecting unit must be at least 400 mm. Note that the reinforcement of the monolithic slab should be done so that the connections are staggered. The upper and lower layers must be strengthened using an U-shaped connection.

It should be known that the calculation of a monolithic plateoverlap must assume a uniform distribution of loads in its thickness. That is, the main load receives the bottom layer, subjected to a continuous stretching action. Above the reinforcing base will shrink. In general, when carrying out calculations, you should always keep in mind and insert in especially problem points of the amplifying elements, but there are general laws.

Thus, the reinforcement scheme of a monolithic slab in the lowermiddle part necessarily provides for the laying of additional rods. Necessarily so strengthen plates, lying in places of connection of overlappings and bearing walls. Of course, there should be similar inserts in places of holes or other positions subject to additional loading. For example, these should be provided in the doorways and window openings.

In places above the bearing walls, on the contrary,reinforced upper mesh. If you are going to use columns, then in this case you can not do without using complex architectural programs for calculations, since such situations are not included in the number of standard ones.

It is important to note that the pouring of concrete in the mandatoryorder should be carried out using a concrete pump. It is very important to use vibration seals. Do not forget that in order to avoid cracking of concrete on the surface of the plate it is necessary to wet it with water periodically for two to three days after pouring.

Thus, the reinforcement of the monolithic slab is performed in strict accordance with the building standards and standards.
