To ensure the strength of the building, it is necessary to select the correct floor slabs. A variety of material used is as important as the work algorithm. After all, all plates have their own characteristics, which you need to know about to perform the correct installation.
Continuous slab -cutting slabsContinuous plates
Continuous plates have a sufficiently high strength due to the use of high quality cement mortar and reinforcement. When forming the plates, wooden formwork is used, in which the reinforcing element is placed. Only after that concrete is poured. To freeze the concrete block and gain maximum strength, it needs about four weeks. This period may increase or decrease. For example, in conditions of high humidity or low temperature. Plates are great for the construction of non -standard structures. They are also used in the construction of industrial -type objects subjected to vibrations.
Hollow slabs
Hollow slabs can withstand a smaller load than solid slabs, which is due to the presence of a cylindrical cavity in the middle of the structure of the cavity. Due to this, the weight of the product is significantly reduced, however, heat and sound insulation characteristics worsen. The advantage of these plates is that in hollow elements you can lay various communications. Such plates are characterized by simplicity of installation, a long period of operation, reliability, as well as the possibility of reuse.
Disadvantages of hollow plates:
High costs for transporting and storage of products.The inability to use unique structures in the construction.The end parts of the products must be closed.
Ribbed slabs
Ribbed plates have up to two ribs of stiffness, for which they got the name: “P-shaped”. Due to the presence of stiffener ribs, the design withstands bending loads without problems.
During the production of ribbed plates, they can be used: lightweight concrete; heavy concrete.
At the first stage of the production of the product, it is placed in it: a heated reinforcing element and mounting loops. After that, the concrete mixture is poured. To give concrete maximum density, it is exposed to vibration. It should be borne in mind that ribbed plates are not used in the construction of residential buildings (both multi -storey and low -rise). They are used only for the construction of industrial facilities and buildings of technical purpose.
