在钢结构工程中,网架结构部分可以作为一个子分部工程,也可以作为一个分项工程。网架结构一般由多根杆件按照一定的网格形式通过节点连结而成的空间结构。具有空间受力、重量轻、刚度大、抗震性能好等优点;网架结构广泛用作体育馆、展览馆、俱乐部、影剧院、食堂、会议室、候车厅、飞机库、车间等的屋盖结构。本文现就钢网架结构的安装施工方法做浅要研究。 In the steel structure project, the structure of the grid structure can be used as a sub-division project or as a sub-project. Grid structure generally consists of a plurality of rods in accordance with a certain form of grid through the nodes to form a space structure. The utility model has the advantages of space force, light weight, large rigidity and good anti-seismic performance. The grid structure is widely used as a roof structure of a gymnasium, an exhibition hall, a club, an auditorium, a conference room, a waiting hall, an airship hangar, a workshop and the like. In this paper, the steel grid structure of the installation and construction methods to do a minor study.
