23 Jul Sub-rigid roof structure plate structure
Abstract
The utility model discloses a sub-rigid roof structure plate structure. The unit concrete is provided with a rigid structure layer and a sub-rigid structure layer, the sub-rigid structure layer is provided with a concrete layer, the bottom of the concrete layer is provided with a steel wire mesh, the steel wire mesh divides large stress borne by the concrete layer of the sub-rigid structure layerinto small stress, and through stress recombination, tensile stress borne by the unit concrete is smaller than ultimate tensile stress of the concrete. The common problem of building roof leakage quality in roof waterproof engineering is solved. Multiple, severe and difficult-to-repair properties exist; according to the sub-rigid roof structure, the steel wire mesh is arranged on the surface layerto form stress recombination; the tensile resistance of the surface layer is reduced, a roof water storage and soil covering mode is adopted, the working environment of drying shrinkage of concrete in air and the self-expansion process of a concrete cement-based material in a water environment are changed, and derivative substances fill loose tissue holes, increase the density and improve the durability and the waterproof function.
