Assembled breathable filling box

Abstract

The invention relates to an assembled breathable filling box and a fabrication method thereof, and belongs to the field of common building construction. The filing box (1) comprises an upper assembly (2), a lower assembly (3) and stiffeners (4), wherein the upper assembly and the lower assembly are prepared from strip-shaped metal sheets (5) which are smaller than 1mm in thickness; each metal sheet is divided into a panel (7), two side plates (8) and two additional sides (9) by four meander lines (6) on the metal sheet; dense meshes (10) are formed in the panel; two ends of each metal sheet are respectively bent 90 degrees along the meander lines towards different directions, so as to form the upper assembly and the lower assembly, which respectively include three surfaces and two sides and are in a U-shaped structure; at least two stiffeners are arranged in each direction in the upper assembly and the lower assembly; and the upper assembly and the lower assembly are oppositely buckled to form the filling box. The filing box provided by the invention is convenient to produce, transport and install and good in mechanical property; and a hollow floor system formed by the product is relatively good in reliability, shock resistance and crack resistance.

Description

(1) Technical field [0001] 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. (2) Background technology [0002] 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. [0003] In the early hollow floor, 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 importance of cement products, I once proposed polystyrene foam A class of filling materials; the above technologies are...

AI Technical Summary

Problems solved by technology

[0008] 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 rigidity 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
