How is the reinforcement of the monolithic slab

In any high-rise building will not be able to do without slabs between floors.Most of them are exposed reinforcement, as this kind of products have increased strength.Although exactly the same way today made blocks for stairways and window and door jumper.So how is carried out reinforcement monolithic slabs?

First of all you have to correctly calculate all indicators for the implementation of such an operation.Firstly, it is strongly recommended that you use for this purpose only reinforcing elements of the class A3.Their diameter varies between 8-14 mm, depending on the projected load on the structure.

Typically, reinforcing monolithic slabs made in two layers.Simply stated, the valve is disposed in the upper and lower plates.Note that the top metal layer of concrete reinforcement must be at least 20 mm.If there are no nets elements are joined by means of special binding wire.

Attention!

for this purpose is unacceptable to use welded!

All elements must overlap a solid layer, override not allowed.Only in case of lack of its length can be increased by means of tie rods, but the diameter should be 40 times greater than that for you use valves.For example, if the grid plate used with rod diameter of 10 mm, the connecting node must be not less than 400 mm.Note that the reinforcement of the monolithic slab must be carried out so that the connections are staggered.The upper and lower layers to be strengthened by using U-shaped connection.

should be aware that the calculation of monolithic slab must assume an even distribution of load in her column.That is the main load gets lower layer undergoes continuous tensile action.Top reinforcing base will shrink.In general, when the calculations you should always keep in mind the insert in particular trouble spots reinforcing elements, but the overall pattern is still there.

So, reinforcing monolithic circuit boards in the lower middle portion of the gasket is required to provide additional rods.Necessarily so amplified plate lying in the joints of the supporting walls and ceilings.Of course, in other locations or positions of the holes exposed to an additional load should be similar to the insert.For example, they are required to provide in the door and window openings.

In areas of load-bearing walls, by contrast, increased mesh upper.If you are going to use the column, in this case, can not do without the use of complex architectural programs for calculations, since such a situation in a number of standard are not included.

Importantly, the pouring of concrete necessarily be carried out using a concrete pump.It is important to apply the vibratory compactors.Do not forget that in order to avoid cracking of concrete on the surface of the plate must be within two or three days after pouring periodically moisten with water.

thus reinforcing monolithic slab is performed in strict compliance with building regulations and standards.
