Installation method of ultra-large polygonal curved surface steel structure
The invention provides a mounting method for an ultra-large polygonal curved surface steel structure, and belongs to the technical field of steel structure mounting. The installation method comprises the following steps: drawing a ground sample drawing and a track drawing in an installation site according to a design drawing; mounting a rail and a base; a lower truss assembly is mounted on the base; mounting a lower shell on the lower truss assembly; assembling an upper shell; mounting an upper truss assembly and mounting an upper shell to the upper truss assembly; and assembling to form the polygonal curved surface steel structure. The ultra-large polygonal curved surface steel structure component is divided into the upper part and the lower part which are assembled on the ground respectively, and then the upper part and the lower part are folded in an integral lifting and integral sliding mode, so that on-site installation is completed, the high-altitude operation and high-altitude measure cost is greatly reduced, the on-site manufacturing and installation efficiency is improved, and the construction cost is reduced. The construction period is shortened, the requirement for the hoisting height of hoisting machinery is lowered, and manufacturing and installation of the ultra-large polygonal curved surface steel structure component in the height-limited space are achieved.
本发明提供一种超大型多边形曲面钢结构安装方法，属于钢结构安装技术领域。安装方法包括：按设计图纸，在安装场地画出地样图和轨道图；安装轨道和底座；在底座上安装下部桁架组件；将下部壳体安装在下部桁架组件上；拼装上部壳体；安装上部桁架组件并将上部壳体安装至上部桁架组件；拼装形成多边形曲面钢结构。本发明通过将超大型多边形曲面钢结构部件划分为上、下二个部分在地面分别组装后，再通过整体提升、整体滑移的方式将上、下二个部分进行合拢从而完成现场安装，大大减少了高空作业和高空措施费用，提高了现场制作安装的效率，节约工期，降低了对起重机械的起吊高度要求实现高度受限空间内超大型多边形曲面钢结构部件的制作安装。
