Combined frame of steel meshed body and organic object for pore forming of cast-in-place hollow floor

Abstract

The invention provides a combined frame of a steel meshed body and an organic object for the pore forming of a cast-in-place hollow floor. According to the combined frame, the steel meshed body comprises a meshed plate, reinforcing ribs, a connecting plate and edge reinforcements, wherein the meshed plate, the reinforcing ribs, the connecting plate and the edge reinforcements which interact with each other form an integral structure; a row of bending lines are pressed in the vertical direction of the reinforcing ribs of the steel meshed body; when the steel meshed body is in lap joint end to end on the surface of the top of the frame, the lap joint amount is less than or equal to the surface area of the surface of the frame top, and a surface reinforced layer is formed directly; the organic object comprises air bags or polyphenyl blocks; the organic object forms the other two side walls on the side of the combined frame and is supported in inner space between the surface of the frame top and the surface of the bottom of the frame to control the height of the combined frame of the steel meshed body. According to the combined frame, the non-sealed combined frame of the steel meshed body and the organic object replaces the conventional full-sealing hollow filling body and solid filling body as the pore-forming technology of the cast-in-place hollow floor to solve the problems of difficulties in the blocking and supporting of the other two side walls on the side of the steel meshed body frame and facilitate the implementation of the cast-in-place hollow floor.

Description

technical field [0001] The invention relates to a filler member for forming holes in a cast-in-place hollow floor, in particular to a composite frame of a steel mesh body and an organic object for forming holes in a cast-in-place hollow floor. Background technique [0002] At present, in the technical field of cast-in-place reinforced concrete hollow floors, fully-sealed filler components are usually used to form holes and form hollow floors, such as ZL200410082381.9 "a hollow small ribbed floor" declared by the inventor, which uses thin-walled The filling body of the box body is buried in the small dense ribbed floor to form a hollow layer with a "T-shaped" stress section, which solves the problem of smooth roof of the small dense ribbed hollow floor with a "T-shaped" stressed section. However, there is no designed stress reinforcement between the bottom of the thin-walled box filling body and the hollow floor formwork, and a layer of crack-resistant steel wire mesh must be...

Problems solved by technology

[0006] The purpose of the present invention is to combine the advantages of the steel mesh body with the performance of organic objects to provide a brand-new technology for forming holes in cast-in-place hollow floors. Floor, optimize the existing hole-forming technology of the cast-in-place hollow floor, and overcome the defects of vertical anti-floating, horizontal displacement, and poor compatibility caused by the existing hole-forming technology of the hollow floor. ; especially by using the innovative combination of steel mesh and organic objects, the steel mesh of inorganic objects becomes the main body of the combined frame, which is the same material as the reinforced concrete of inorganic objects, and ha
