AI Technical Summary

Technical Problem

The steel bar truss bearing plates are prone to deformation and damage during transportation and construction, and the galvanized steel plate bottom mold cannot be directly plastered and decorated, and the application range is limited.

Method used

UHPC ultra-high strength concrete layer and dense hole steel plate are used, and the steel bar truss is fixed on the steel plate. The concrete layer wraps the steel plate as a construction formwork and is used directly as a floor slab. Putty can be directly scraped after construction is completed.

Benefits of technology

It improves the performance and construction efficiency of the floor bearing plate, solves deformation and damage and decoration problems, realizes direct plastering and decoration, and expands the scope of application.

Abstract

The steel bar truss floor support plate comprises a steel plate, a steel bar truss and a concrete layer, concrete layers are attached to the upper surface and the lower surface of the steel plate; the steel plate is a dense-hole steel plate. The utility model provides a UHPC (Ultra High Performance Concrete)-dense-hole profiled steel sheet steel bar truss floor support plate, which is mainly characterized in that a profiled steel sheet is provided with holes, and floor steel bars and pipelines can be arranged on site; the UHPC-dense-hole profiled steel sheet steel bar truss floor support plate is directly used as a construction formwork for pouring concrete, putty can be directly applied after construction is completed, a suspended ceiling is not needed, and the floor clearance is improved; the UHPC bottom plate is prefabricated in a factory, the product quality is guaranteed, damage is avoided in the transportation process, direct stacking can be achieved, and the transportation and construction efficiency is improved. The floor support plate can be moved by workers due to the lightweight design, and construction is facilitated.
