Embodiment Construction

[0024] The invention will be further described below in conjunction with the accompanying drawings.

[0025] figure 1 It is the folded diagram of the ribbed stencil in the first embodiment of the present invention, such as figure 1 As shown, special mechanical equipment such as unwinding machine, punching machine system, expansion system, and shearing machine will be used to make expanded metal mesh body and press the mesh 2 with bending marks 3. The main body of the mesh 2 around the ribbed steel mesh hole 1 is bent one by one at the marks.

[0026] figure 2 It is the ribbed steel mesh openwork end mesh structure of the second embodiment of the present invention figure 2 A. figure 2 B, such as figure 2 As shown in A, the factory cuts the length of the required end mesh 4 steel mesh body according to the height of the ribbed steel mesh. Use special equipment to press the thin steel sheet 4a into a V shape, wrap the two ends of the end mesh 4, and then use a punching ...

Abstract

The invention discloses a ribbed steel mesh hollow for a cast-in-situ hollow floor slab. The ribbed steel mesh hollow consists of a hollow mesh, a supporting mesh, a hollow end mesh, wherein the hollow mesh, the hollow end mesh and the supporting mesh are made of a pure metal material; the hollow mesh forms the periphery of the ribbed steel mesh hollow; the hollow end mesh closes the ribbed steel mesh hollow and the supporting mesh to form a hollow end section shape of the ribbed steel mesh hollow; the supporting mesh controls the height of the interior space of the ribbed steel mesh hollow; the hollow mesh and the hollow end mesh are made of a steel mesh body; the steel mesh body comprises steel plate enlarging mesh holes, a V-shaped rib and a reversing connecting sheet; the enlarging mesh holes in the two sides of the reversing connecting sheet are in different directions; the V-shaped rib has the height of greater than 6mm; at least four measuring shaping marks are pressed in the vertical direction of the V-shaped rib of the steel mesh body of the hollow mesh; the supporting mesh is made of a steel mesh body or a steel bar mesh body. The hollow floor slab is cast by using the ribbed steel mesh hollow, and the ribbed steel mesh hollow is directly cast in situ into concrete on the edge of a hollow, so that a temperature crack of the floor slab is inhibited.

Description

technical field [0001] The invention relates to a non-centering hole-forming technology for a cast-in-place cavity floor, in particular to a ribbed steel mesh for a cast-in-place cavity floor. Background technique [0002] At present, in the technical field of cast-in-place reinforced concrete hollow floors, a fully sealed filling member is usually used to form a hollow floor, such as the ZL98231113.3 concrete thin-walled cylindrical member declared by the inventor, which is made into a sealed cylindrical filling body. In order to realize the cast-in-place hollow floor, a tubular hollow filling body is provided, which solves the technical problem of non-centering hole formation in the cast-in-place hollow floor. However, due to the sealed tubular hollow filling body, there are defects such as difficult fixing, high buoyancy, high density and heavy weight, inconvenient production, transportation and on-site construction, low evacuation rate, and inability to form a large-scal...
