Abstract
With the rapid development of the construction industry, the country has a higher demand for scaffolding engineering, so it is very necessary to develop and promote the application of wheel buckle scaffolding. Steel tube scaffold with wheel buckle has the characteristics of clear transmission and good mechanical performance. In order to study the structural performance of steel tubular scaffolding with wheel buckle, the single span three-step element frame was tested. The failure mode and ultimate bearing capacity of the frame are obtained. The finite element software Sap2000 was used to conduct 3d modeling and linear buckling analysis of scaffolds in the test. The results of experiments and finite element analysis show that the failure type of steel tubular scaffolding is the overall torsional instability failure. The connection stiffness at the joint of the diagonal brace fastener has a great influence on the wheel-buckle scaffold. The diagonal brace has obvious influence on the bearing capacity of steel tubular scaffolding body with buckles.
Highlights
Our country is in a stage of high-speed development of economy, construction projects are springing up and developing vigorously, construction and installation engineering of new technologies, new processes and new materials were the new, combined with the country in recent years, successively for building design, construction, supervision, quality acceptance specification and construction standards of revision, the original technical system has not adapted to the requirement of modern construction enterprise development
There are several kinds of the types of scaffolding, scaffold for wheel button and disc scaffolding are similar, but due to the high price of fastener scaffold, combined with the actual use in China, the domestic production enterprises carry out technical transformation to make it more convenient at a lower cost, that round buckle scaffold arises at the historic moment
In this paper, based on the existing research experience, the single-span three-step steel tubular scaffolding is tested and analyzed, and the failure state, ultimate bearing capacity and related factors are obtained through the analysis of Sap2000 finite element software
Summary
Our country is in a stage of high-speed development of economy, construction projects are springing up and developing vigorously , construction and installation engineering of new technologies, new processes and new materials were the new, combined with the country in recent years, successively for building design, construction, supervision, quality acceptance specification and construction standards of revision, the original technical system has not adapted to the requirement of modern construction enterprise development.
