Steel bar truss floor bearing hollow composite board and construction method thereof

Abstract

The invention relates to a steel bar truss floor support combined hollow slab and a construction method thereof, the steel bar truss floor support combined hollow slab comprises a bottom profiled steel sheet, steel bar combined frames, hollow formworks and formwork connecting pieces, each steel bar combined frame is formed by three plane trusses, the cross section of each steel bar combined frame is a door-shaped combined frame, and the hollow formworks are longitudinally arranged along the bottom profiled steel sheet in a full-length mode and transversely arranged at intervals. The hollow formwork comprises an in-frame formwork arranged in the middle of the steel bar combination frame and an inter-frame formwork arranged in a gap between every two adjacent steel bar combination frames, the arrangement height of the in-frame formwork is the same as that of the inter-frame formwork, and the hollow formwork is fixedly connected with the steel bar combination frames through formwork connecting pieces. The large-span steel bar truss floor support plate can be achieved, meanwhile, the advantages that a traditional steel bar truss floor support plate is high in construction speed, bidirectional in stress and free of formwork erecting can be achieved, the defects of a profiled steel sheet composite floor slab are overcome, the construction quality and the use performance of the floor slab are improved, the construction speed is higher, and more energy and materials are saved.

Description

technical field [0001] The invention relates to a steel bar truss floor bearing plate, in particular to a steel bar truss floor bearing hollow composite plate and a construction method thereof. Background technique [0002] With the development of construction industrialization and the improvement of the construction industry's environmental protection requirements for construction sites, the demand for construction construction to speed up the construction progress, reduce the amount of on-site steel binding works, reduce the amount of formwork works and reduce the environmental pollution of the construction site is becoming more and more urgent. Reinforced truss floor decks are currently widely used in various industrial and civil buildings. The traditional profiled steel plate composite floor solves the problem of supporting the formwork, and the construction speed is fast, which is suitable for the construction period of the steel structure, but there are two-way rigidity...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a composite hollow slab of reinforced truss floor bearing and its construction method, to solve the technical problem that the upper and lower chord steel bars of the reinforced truss do not match the number of steel bars required for the actual stress of the floor, resulting in waste of materials. Solve the technical problems of limited span of reinforced truss floor deck, self-heaviness and waste of materials
