Otherwise called the flooring – a structural layer laid on the beams. Acts as a shield, tolerates horizontal loads on the wall. As a black floor in beam floors, different slabs are used, for example, plywood, stoves without cladding, stoves with fibers in the correct order. In ceilings with metal beams, plywood slabs or boards are used, which are simultaneously a black floor and base. The basis does not have a constructive load, however, it creates an even and smooth base for clean sex. The basis can be used to align a small level of level, which occurs due to different sizes of finishing materials. As the basis, plywood, hard felt slabs and chipboard are usually used. It is advisable to leave gaps 1 – 3 mm between the plates to ensure the freedom of expansion. With the black floor, the granite of the steps together is perfectly combined together, they create an excellent interior.
Small black floor areas can be made of concrete, which will be a base for ceramic tiles.
Concrete collects energy, because it quickly heats up in the sun. Under the concrete floor, the structure is lowered to align the layer of concrete with the adjacent black floor. How the basis is used plywood, resistant to wet concrete. It is best to use a concrete layer, which is reinforced with fiberglass, such a layer fits on a typical black floor for cladding with ceramic tiles. The thickness and level of black concrete floor will depend on the material of the flooring. The floor beams themselves are emphasized in the support beam on the ledge of the walls of the foundation or on the low wall of the frame.
The beams are attached by steel connecting corners to the outer beam made of impregnated wood, which lies on the wall of the foundation. In the walls of 38 by 39 mm, it is necessary to lay a layer of thermal insulation between the double crowning beam and the outer beam.
Когда под бетонным полом лежат балки меньшей высоты, тогда надо уменьшать их пролет или ширину. In areas where the concrete plate is located under the sun and heats up strongly, thin concrete floors are used. Double support beam works like a leveling board.
