摘　　要：当前各地区各类型的新建大型场馆逐渐增多,为保证体育场建筑规模及外观效果、钢网架屋盖渐渐成为主流结构形式。为提高施工效率大型场馆钢网架结构在施工过程中多采用分块吊装的形式,需要在吊装过程中搭设支撑胎架,直到网架结构整体安装卸载完成后方可拆除支撑胎架。而在建筑平面布置中通常支撑胎架的位置还有裙房结构。工期紧张的情况下裙房区域由于不在关键线路上常常作为施工后甩区,直接造成了屋盖钢网架支撑胎架与相应裙房区域主体结构产生作业面冲突。为此采用模型计算分析网架结构安装过程中构件的应力应变情况,同时采用增加辅助稳定措施的方式,总结形成提前递进式卸载拆除钢屋盖支撑胎架的施工工艺。In order to ensure the construction scale and appearance effect,the steel mesh roof has gradually become the mainstream structure form.In order to improve the construction efficiency,the steel grid structure of large stadiums and gymnasiums adopts the form of block hoisting in the construction process,it is necessary to set up the supporting tire frame in the hoisting process,until the whole installation and unloading of the grid structure is completed before removing the supporting tire frame.And in the building layout often support the position of the tire frame and skirt structure.Under the condition of tight construction period,the skirt area is often used as the dumping area after construction because it is not on the key line,which directly causes the conflict between the roof steel grid support tire frame and the main structure of the corresponding skirt area.Therefore,the model is used to calculate and analyze the stress and strain of the members during the installation of the grid structure,and the construction technology of the steel roof support frame is summarized by adding auxiliary stability measures.
