摘要
传统混凝土悬挑平台建筑结构支撑系统施工方法受施工条件限制,在特定的结构形式及施工环境下施工困难、施工难度大、安全风险高。结合工程案例,介绍了一种超高、长悬挑筒体结构悬挑钢结构桁架支撑系统设计及结构影响性分析方法,结合结构特点制订了合理的施工工艺流程,并指出了钢支撑安装要点及管件做法,解决了超高、长悬挑现浇混凝土结构施工技术难题。
The construction method of the traditional concrete cantilever platform structure support system is limited by the construction conditions,and it is difficult to construct with high risk in the specific structure form and construction environment.Combined with the engineering case,this paper introduces a design and structural impact analysis method of the steel truss support system of the super high and long cantilever tube structure.Combined with the structural characteristics,the reasonable construction process is developed,and the installation points and pipe fitting methods of the steel support are pointed out,and the technical problems of the construction of the super high and long cantilever cast-in-place concrete structure are solved.
