Large-span hangar installation method based on deformation control in whole construction process
The invention relates to a large-span hangar installation method based on deformation control in the whole construction process, which belongs to the technical field of steel structures, and comprises the following operation steps of: 1, splitting into a net rack and a truss, then splitting into a plurality of large modules, and then splitting the large modules into a plurality of small modules; secondly, supporting columns are arranged on the construction site, meanwhile, small modules of the net rack and the truss are assembled, and at the moment, arching is conducted in the Z direction; thirdly, the small modules are assembled into a large module, and at the moment, arching is conducted in the X direction, the Y direction and the Z direction; and fourthly, the large net rack modules are assembled into the net rack, and the large truss modules are assembled into the truss. Fifthly, the net rack is lifted by 3 m firstly. And sixthly, the net rack lifted by 3 m and the truss on the ground are spliced. And seventhly, the hydraulic lifter on the truss is removed. And 8, the complete steel roof structure is lifted. And ninthly, connecting rod pieces of the peripheral structure are supplemented. And tenthly, the inlaying segment is supplemented finally. The problem of horizontal displacement control of the top of the supporting column and the steel roof in the steel roof lifting process is solved.
本发明涉及一种基于施工全过程变形控制的大跨度机库安装方法，所属钢结构技术领域，包括如下操作步骤：第一步：拆分为网架和桁架，再拆分为若干大模块，大模块再拆分为若干小模块。第二步：在施工现场布置支撑柱，同时分别拼装网架和桁架的小模块，此时起拱Z方向。第三步：将小模块拼装成大模块，此时起拱XYZ方向；第四步：网架大模块拼装成网架，桁架大模块拼装成桁架。第五步：先将网架提升3米。第六步：将提升3m后的网架和在地面上的桁架拼接起来。第七步：撤销桁架上的液压提升器。第八步：提升完整钢屋盖结构。第九步：补充与周边结构的连接杆件。第十步：最后完成在补充嵌补段。解决钢屋盖提升过程中支撑柱柱顶和钢屋盖水平位移控制问题。
