Construction method of multi-line long span inverted trapezoidal space truss roof system
The invention provides a construction method of a multi-line long span inverted trapezoidal space truss roof system. The construction method comprises the steps of: S1, a construction preparation; S2,surveying and setting-out: a measurement of a steel trestle axis and a re-measurement of a scaffold position; S3, pre-embedding of roof components; S4, assembling of a steel trestle; S5, assembling of a hoisting machine; S6, installation of an assembling scaffold; S7, assembling of a giant space tube truss; S8, hoisting of the truss; S9, welding at high altitude; and S10, unloading of a structure. The construction method of the multi-line long span inverted trapezoidal space truss roof system has the characteristics of reasonable stress, high bearing capacity, large rigidity and convenient construction.
本发明提供一种多线型大跨度倒梯形空间桁架屋盖体系施工方法，所述施工方法包括：S1、施工准备；S2、测量放线：钢栈桥轴线测量；胎架位置复测；S3、顶板构件预埋；S4、钢栈桥拼装；S5、吊装机械组装；S6、拼装胎架安装；S7、巨型空间管桁架拼装；S8、桁架吊装；S9、高空焊接；S10、结构卸载。本发明具有受力合理、承载力高、刚度大、便于施工的特点。
