Installation and construction method for large-span asymmetric space reticulated shell structure
The invention provides an installation and construction method for a large-span asymmetric space reticulated shell structure. Comprising the following steps of installation of a supporting steel column, positioning installation of a first-stage cast steel joint on the upper portion of the steel column, installation of a crotch column, positioning installation of a second-stage cast steel joint, installation of a second-stage crotch column on the upper portion of the crotch column, installation of a steel joint, positioning of a roof hub joint and welding installation of a roof steel beam. The edge sealing steel beam is installed, and other accessory components are installed. Compared with bulk welding of a traditional steel structure, the mode of assembling the small hub joint units in the ground operation area and hoisting and welding in the air is adopted, the operation difficulty is reduced, the construction progress is accelerated, the assembling and welding precision problem caused by too many steel components in the steel structure hoisting process is effectively solved, and the construction efficiency is improved. And potential safety hazards in the construction process are reduced.
本发明提供了大跨度非对称空间网壳结构安装施工方法，包括如下步骤：支撑钢柱的安装、钢柱上部一级铸钢节点的定位安装、树杈柱的安装、二级铸钢节点的定位安装、树杈柱上部二级树杈柱的安装、钢制节点的安装、屋面毂节点的定位、屋面钢梁的焊接安装、封边钢梁的安装以及其他附属构件的安装。本发明通过采用地面作业区毂节点小单元拼装，空中吊装焊接的方式，较传统钢结构的散装焊接：减小了操作难度，加快了施工进度，有效的解决了钢结构吊装过程中由于钢构件过多产生的拼装及焊接精度问题，减少了施工过程中安全隐患等优势。
