High-rise building long-span steel bar truss floor deck and production technology thereof

Abstract

The invention discloses a high-rise building long-span steel bar truss floor deck, and the high-rise building long-span steel bar truss floor deck comprises several soffit formworks and several steelbar trusses, wherein the soffit formworks are in buckled connection with the steel bar trusses, the soffit formwork comprises an upper bearing plate, a lower loading plate and a connection column, thesteel bar trusses pass through the upper bearing plate, the upper bearing plate comprises a buckling plate, a splicing plate and a buckle, and the splicing plate and the buckling plate are in cooperation with the steel bar trusses through the buckle; the invention also discloses a production technology of the high-rise building long-span steel bar truss floor deck, and the technology comprises the following steps: preparing the soffit formworks; assembling the steel bar trusses; and assembling a steel bar truss floor deck. On the basis of the prior art, a structure of the steel bar truss floor deck is improved, the existing single-layer soffit formworks is changed into be double-layer, thereby, leakage of grout is avoided, further, the buckling plate and the splicing plate are mutually fitted, thus, the upper bearing plate can be fixed with the steel bar trusses, then, an aim of avoiding weld penetration of the soffit formworks, a risk of leakage of grout is avoided, and the steel bartruss floor deck can be used in high-rise buildings.

Description

technical field [0001] The invention relates to the field of building technology, in particular to a large-span reinforced truss floor deck of a high-rise building and a production process thereof. Background technique [0002] The mechanical properties of reinforced truss floor slabs are basically the same as those of traditional cast-in-place slabs, and are widely used in the construction of various buildings. The reinforced truss floor deck is a combined formwork that processes steel bars into reinforced trusses and welds the reinforced trusses and bottom formwork. In the existing use process, due to irregular welding, it is easy to cause the bottom formwork to be welded through, making There is a risk of grout leakage when the steel truss floor deck is poured with cement. In high-rise buildings, it is necessary to use a long-span steel truss floor deck, which increases the risk of using a long-span steel truss floor deck. Therefore, it is urgent to carry out Improve. ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems in the prior art that the bottom formwork of the existing reinforced truss floor deck is easy to be welded through and has the risk of grout leakage and is not suitable for high-rise buildings, a large-span reinforced truss floor deck for high-rise buildings is proposed and its production process
