Reinforcement of the floor slab: structural features
The creation of monolithic ceilings in the construction of country houses allows to obtain a number of advantages in comparison with precast reinforced concrete.
First, it does not require the involvement of heavy lifting equipment, cranes and other machines.This method allows you to arrange overlaps forobjects that have non-standard dimensions. Also, a monolith (concrete slab) is distinguished by good strength characteristics of buildings. Reinforced concrete materials are ten times stronger than their analogues made from wood. In addition, they have high fire-resistance properties.
When working on the installation of structural dataelements, a special role is played by operations that include reinforcement of the slab. The thickness of the product depends entirely on the width of the span. According to the technology, this figure is 30-th part of the distance between the capital bearing walls of the building. So, if the width of the span is 6 meters, the thickness with which the reinforcement of the slab is performed will be equal to 20 centimeters. This characteristic of a monolith can not be abused in any case. If you make the design already, then you should increase the consumption of rolled metal for the work.
The reinforcement of the floor slab is made withusing steel rods with a diameter of 8 to 14 mm. The choice of the dimensions of the reinforcement depends entirely on the load forces determined by calculations. If the thickness of the monolith is less than 15 cm, then it is reinforced with one layer of iron. If this parameter is exceeded, reinforcement of the slab will require the inclusion of two layers of steel rods.
In the second case, the first wall of the reinforcement is mountedat the base of the plate, the second grid is knitted from above. With the arrangement of individual rods, cells with sizes of 15 by 15 or 20 by 20 centimeters are produced. In addition, measures are being taken to further strengthen the monolithic ceilings in the middle sector of the slab and on the supporting parts. To do this, additional meshes are used in the base of the structure and reinforce the reinforcement of the slab.
Do not forget about the additional strengthening of individual areas, where the load forces and holes are concentrated.These operations are carried out by means of separateThe length of the rods varies from 450 to 1550 mm and depends entirely on the width of the span and the load forces. Often the main reinforcement is of a continuous type, and near the holes, an additional reinforcement is produced.
With the help of reinforcement, a foundation is createdstructure and slab of the well. When manufacturing the base plate of the building, the steel grilles are placed at different levels of the layer being poured in height. All steel rods must be welded. The installation of the grate is carried out in such a way that, due to the pouring of concrete, all the metal parts have been immersed in it. The protective layer of the solution will prevent corrosion on the surface of steel structures.
Reinforced slabs are widely used in the construction of multi-storey brick and reinforced concrete buildings.
