MULTI-CAPACITY PRE-STRESSED CERAMZITE CONCRETE OVERLAPPING PLATE WITH INCREASED ANCHORING OF THE VALVES

摘要

The utility model relates to the production of building structures, in particular to the production of hollow-core reinforced concrete floor slabs by the method of stand-off formwork. , and working reinforcement 6. The slab body is completely made of expanded clay concrete, in which high-strength expanded clay gravel of round shape, a mixture of fractions 0-20 mm, with low water absorption is used as a large aggregate, which creates a dense structure of a molded monolith along the entire length of the product, and As working reinforcement, steel reinforcing seven-wire, prestressed ropes 6, placed in the lower part of the slab body, were used. The technical result of using the proposed claydite-concrete floor slab is to improve the quality and reliability of the structure, as well as to eliminate the sealing of voids at the ends of the slabs, in the case when the value of stresses in the walls from the loads of the overlying floors should not exceed 2.4 MPa. Execution of the slab body from expanded clay concrete using high-strength expanded clay gravel of a round shape as an aggregate, in conjunction with steel seven-wire prestressed ropes, allows reliable anchoring of working reinforcement without the use of additional means. 2 ill.
