In modern construction, various types of reinforced concrete structures are widely used. These include foundation blocks that are used in the construction of residential and industrial buildings. Depending on the weight load on the supporting structures in the production of blocks, all kinds of additives are used. This allows the use of FBS in various climatic zones.
As a rule, the production of blocks is carried out in an industrial way, which makes it possible to establish a mass production of this type of product. FBS blocks are of high density, due to which, during the operation of the foundation, moisture penetration into its structure is excluded. Currently, industry produces three types of blocks that differ in their size and technical characteristics:
FBS with cutouts that are designed to install jumpers and laying communication networks;
continuous blocks;
hollow blocks that are distinguished by high thermal insulation characteristics.
As a rule, prices for FBS blocks depend on the parameters, sizes and materials used for their production. The design of the blocks is two belts connected by special racks, as well as the walls located above the lower belt. In the transverse section, blocks have a trapezoidal shape. For production, a metal formwork is used, collected from sheets up to 8 mm thick. It has a bottom and a couple of seats designed to install sealing vibrators.
With small production volumes for filling blocks, ordinary forms are used. They are installed on special sites. Vibration forms are used in large enterprises specializing in the production of reinforced concrete products for various purposes. Sedentary concrete is used to fill the forms. The performance in this case is about 40 blocks in one form per shift. Concrete for standard forms is prepared in gravitational or forced type mixers. Working equipment is moved using lifting mechanisms with manual or mechanical drive.
