An assembled breathable filling box

Abstract

The invention relates to an assembled ventilating filling box and a manufacturing method thereof, belonging to the field of general building construction. The filling box (1) includes an upper assembly (2), a lower assembly (3), and a stiffener (4). The upper assembly and the lower assembly are made of strip-shaped metal sheets (5) with a thickness of less than 1 mm. The bending line (6) divides the metal sheet into 1 panel (7), 2 side panels (8) and 2 additional edges (9). The ends are respectively bent 90° in the same direction along the bending line to form the upper and lower components of a U-shaped structure with 3 faces and 2 sides. Install at least 2 stiffeners in each direction of the upper and lower The upper and lower assemblies are snapped together to form a filling box. The filling box of the invention is convenient for production, transportation and installation, and has good mechanical properties, and the hollow floor formed by the product has good reliability, shock resistance and crack resistance.

Description

[0001] (1) Technical field [0002] The invention relates to a filling material in a reinforced concrete hollow floor structure, in particular to an assembled ventilating filling box and a manufacturing method thereof, belonging to the field of general building construction. [0003] (2) Background technology [0004] In the field of construction, with the increasing number of long-span concrete structures, more and more floor slabs adopt hollow-core floor structure technology. Replacing part of the concrete with lightweight filling materials will basically not affect the mechanical performance of the structure, but it can greatly reduce the self-weight of the structure. [0005] In the earlier hollow floors, scholars represented by Qiu Zeyou and Wang Benmiao proposed to use high-strength cement to make cement pipes and cement boxes as filling materials; later, in view of the weight of cement products, I once proposed polystyrene foam. The above-mentioned technologies are wide...

AI Technical Summary

Problems solved by technology

[0011] In the existing hollow floor technology, there are problems such as the large buoyancy of the filling material that makes construction difficult, or the integrity of the filling material is poor, the stiffness is small, the quality of concrete pouring around the filling material cannot be effectively guaranteed, or the transportation cost is too high. The purpose of the present invention is to Provide an assembled breathable stuffing box
