Design of Heavy-duty Transfer Steel Platform Based on Finite Element Method

Abstract

In order to effectively solve the problems of high cracking risk, high safety risk, large construction period impact and high engineering cost of the basement roof of the scaffolding heavy-duty conversion platform, a construction method of heavy-duty conversion steel platform was proposed by referring to the force principle of the above-ground frame structure. The force mechanism, construction process, operation points and quality assurance measures of this method are clarified by theoretical analysis method combined with on-site engineering practice. Finally, the construction method of heavy-duty conversion steel platform is clarified by comparing with the traditional construction method of scaffolding support and reinforcement. The advantages. The research results show that the heavy-duty conversion steel platform mainly transfers the upper heavy lifting load to the steel beam through the subgrade box, and then transmits it to the pile foundation through the steel beam; It is green and environmentally friendly, and can effectively solve the quality and safety problems of underground structures. Compared with the traditional full-house scaffolding support and reinforcement construction method, the cost saving rate of the optimized heavy-duty conversion steel platform reinforcement method is about 12%, which is worthy of further promotion and application.
