Filling box with bottom ventilation net and upper part exhaust holes

Abstract

The invention relates to a filling box with a bottom ventilation net and upper part exhaust holes and a manufacturing method of the filling box, and belongs to the field of building construction. The filling box (1) comprises side frame plates (2), stiffening inner plates (3), a top cover plate (4) and the ventilation net (5), wherein the four side frame plates (2) in end-to-end connection define a rectangular plane; more than one stiffening inner plate is at least arranged in each direction; the stiffening inner plates in different directions are in mutual orthogonality; at least one exhaust hole (6) is formed in the top cover plate; an exhaust net (7) is arranged in each exhaust hole; the top cover plate, the stiffening inner plates and the side plate plates made of nonmetallic materials form a box-shaped structure (8) with an open bottom surface together; the ventilation net is fixed on the bottom of the box-shaped structure in various connecting modes; and the ventilation net and the exhaust nets are made of metal or plastic materials. The filling box provided by the invention has the advantages that the production, the transportation and the installation are very convenient; the mechanical property is good; and a hollow floor slab formed by the product has high reliability, good earthquake-resistant performance and good anti-crack performance.

Description

(1) Technical field [0001] The invention relates to a filling material in a reinforced concrete hollow floor structure, in particular to a filling box with a bottom ventilation net and an upper vent hole 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 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, but cement products are self-heavy. Later, I introduced polyphenylene foam materials into the hollow floor, and...

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 leads to construction difficulties, or the low hollow rate of the floor, low product rigidity, unguaranteed quality of concrete pouring at the bottom of the slab, and difficult pipeline layout. The purpose of the present invention is to provide A filling box with a bottom air mesh and an upper vent hole
