Application of floor slabs
Today we will tell you about hollow floor slabs (PCs), or rather about their operation.
The first stage is the preparation of the support platform. The most important value is the depth of support, which depends on the size, weight of the slab, thickness of the support wall and other factors. Please specify the standards and requirements for a specific case in the SNIP or follow the instructions from the manufacturer of building materials, which must be on the packaging.
The overlap is based not on masonry, but on a so-called monolithic belt, which is a reinforced reinforced concrete beam with a height of 15 cm.
A monolithic belt is a reinforced concrete beam reinforced with AIII rods, which is made under the ceiling in masonry walls. If it is necessary to increase the strength of the structure, for example, due to increased seismic activity, then the belt should be stretched along the entire perimeter of the building. An economical and fast option is a base of two or more rows of solid bricks. The surface of such a base should be as smooth as possible, for this you can use a cement-sand screed.
It is better to support on the short sides, rather than on the sides. It is not necessary to install PCs in the walls if the dimensions do not match - it is better to have gaps between them that can be sealed, for example, with the help of channels.
Laying slabs yourself or hiring professionals is an individual decision. Despite the apparent simplicity, this is a dangerous business, especially when it comes to high-rise work, so participants must have relevant experience. For those who still decide, we offer step-by-step installation instructions.
Prepare the ingredients for the cement-sand mortar, the sand should be coarse, the ratio is 1:3. The mortar should be thick and not spread. It is kneaded immediately before use. Make sure the plate is intact. There may be cracks on it, but the concrete should not crumble around them, and the reinforcement should not be visible. While the slab is lifted by a crane, it is necessary to evenly distribute the solution in 3-4 cm at the resting place. Make sure that the plate is flat on all sides. If the distance between the slab and the support at one end is more than 15 mm, then stones or rebar can be placed. The solution dries almost instantly, so you should work very quickly. Check for horizontal seams and voids. They can be filled with a thick cement-sand mortar. If the plates have holes on the sides, they can be protected from freezing with foam. Now let's deal with the joints between the tiles and the walls.
In order for the structure to be truly strong and durable, all "weak" places should be reinforced and sealed. 1-2 rods are laid between the slabs, and the outer perimeter and the gaps in the inner walls are reinforced with a frame of 2 reinforced rods mounted vertically. Any construction work is fraught with risk and danger to health and life, so remember about safety precautions and be extremely careful.
