Ground assembling method for irregular polygonal steel structure trusses
The invention relates to a ground assembling method for irregular polygonal steel structure trusses. The ground assembling method comprises the following steps that a total station is matched with positioning and setting out, an assembling jig frame is mounted according to gravity center distribution points, and trusses on one side surface are sequentially mounted by adopting a hoisting device; and the subsequent trusses are sequentially mounted according to the sequence, and finally the irregular polygonal steel trusses are assembled on the ground. According to the ground assembling method for the irregular polygonal steel structure trusses, a ground assembling method is adopted, aloft work and support erection are reduced to the maximum extent, operation is convenient, time and labor aresaved, and meanwhile the safety of a construction site is improved. Through the ground assembling method for the irregular polygonal steel structure trusses, the working environment of workers can begreatly improved, influences and restrictions of the environment on the workers are reduced, and the construction efficiency of the workers is greatly improved. Each frame is reasonably assembled onthe ground in sequence from bottom to top, according to the sequence of chord members, supporting, and final web members, so that additional stress and non-uniform internal force in the trusses are greatly avoided.
本发明涉及一种不规则多边形钢结构桁架地面拼装方法，全站仪配合定位放线、拼装胎架按重心分布点进行安装，采用吊运装置依次安装一个侧面的桁架；依次按照上述顺序次安装后续桁架，最终拼装完成一个不规则多边型钢桁架的地面拼装。本发明的施工工法采用地面拼装方法，最大限度地减少了高空作业以及支架搭设，操作方便，省时省力，同时提高了施工现场安全性；该工法可以极大改善工人作业环境，减少环境对作业人员地影响及制约，大大提升了工人施工效率。每榀框架按照从下到上，先弦杆再支撑最后腹杆的顺序依次于地面进行合理的拼装，较大地避免了桁架内附加应力和不均匀内力的产生。
