Steel structural large-span adjustable floor support plate support structure and construction method thereof

Abstract

The invention belongs to the field of floor support plate support, and particularly relates to a steel structural large-span adjustable floor support plate support structure and a construction methodthereof. The steel structural large-span adjustable floor support plate support structure comprises a main body structure steel column, a main body structure steel beam, a steel bar truss floor support plate support beam assembly and a U-shaped hexagon bolt assembly, wherein the outer side of the main body structure steel column is fixedly connected with two connecting plates; the main body structure steel beam is fixedly connected with the connecting plates; the steel bar truss floor support plate is welded with the main body structure steel beam; the steel bar truss floor support plate is supported on the steel bar truss floor support plate support beam assembly. The steel structural large-span adjustable floor support plate support structure has the advantages that the structure is simple; the use is convenient; safety, firmness and reliability are realized; the cyclic turnover use can be realized; the dismounting is convenient; the construction period can be shortened; the multi-layer simultaneous construction can be realized; the steel structural large-span adjustable floor support plate support structure is applicable to the support of any steel bar truss floor support platesystem; considerable economic benefits can be generated; the goals of reducing the cost and accelerating the construction progress are achieved.

Description

Technical field [0001] The invention relates to the technical field of floor deck support, in particular to a steel structure large-span adjustable floor deck support structure and a construction method thereof. Background technique [0002] With the continuous development of construction and the rapid development of technology in the construction industry, the prefabricated construction industry has gradually come into people's sight, and the construction methods of floor slabs have also shown multi-style development. As a new product with environmental protection, simple installation, short construction period, easy quality control and high modernization, the prefabricated steel truss floor deck can not only meet the assembly standards of prefabricated buildings, but also meet the requirements of floor engineering and steel engineering construction. High quality requirements, good floor flatness and high construction efficiency. For mid-span parts with large spans or strict de...

Problems solved by technology

[0003] The purpose of the present invention is to solve the temporary support at the two ends and the middle of the previously constructed steel truss in the prior art. The bottom of the slab uses supporting square wood or steel pipes to be placed under the connecting fasteners as a support. Large, complex construction and installation, non-standard erection, unsatisfactory appearance, poor economic benefits, etc. have been far from meeting the needs of prefabricated building construction. The shortcoming of a steel structure with a large-span adjustable floor deck support structure and its construction method
