A breathable metal filling box

Abstract

The invention relates to a ventilation metal filling tank and a method for manufacturing the same, and belongs to the field of structures of common buildings. The ventilation metal filling tank (1) comprises upper assemblies (2), lower assemblies (3) and supports (4). The upper assemblies and the lower assemblies are made of metal sheets (5), each metal sheet is divided into a face plate (7) and two side plates (8) by two bend lines (6) on the metal sheet, dense meshes (9) are formed in regions of the face plates, slurry stopping sheets (10) are formed by metal sheets punched from the meshes, two ends of each metal sheet are respectively bent by 90-degree angles along the corresponding bend lines towards the same direction to form the corresponding upper assembly and the corresponding lower assembly, each of the upper assemblies and the lower assemblies is of a U-shaped structure with three surfaces, at least three supports are embedded in each upper assembly and the corresponding lower assembly, and the upper assemblies and the lower assemblies are oppositely fastened with one another to form the ventilation metal filling tank. The ventilation metal filling tank and the method have the advantages that the ventilation metal filling tank is quite convenient to produce, transport and mount and good in mechanical property, and a hollow floor system with the ventilation metal filling tank is good in reliability, earthquake resistance and cracking resistance.

Description

(1) Technical field [0001] The invention relates to a filling material in a reinforced concrete hollow floor structure, in particular to a breathable metal 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 heavy weight of cement products, Xu Yan and others proposed Filling materials such as polystyrene foam; the above technologies...

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 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 Provides a breathable metal filling box
