Large-span net rack structure construction method
The invention belongs to the technical field of building construction, and particularly relates to a large-span net rack structure construction method. For solving the problems that in the prior art,a large-span net rack structure is high in mounting construction difficulty, low in safety coefficient, low in construction efficiency and high in construction cost in the construction process, the following scheme is provided, and the method comprises the steps S1, equipment and tools required to be lifted are prepared; S2, between 8 and 9 shafts, upper chord seven grids are spliced on the groundfirstly from a J shaft to an A shaft, seven grids are mounted on a lower chord, and at the time, a net rack can lift 8 tons; S3, two 25t cranes are adopted, and are wholly lifted to the 0.60m elevation J shaft net rack support position; S4, the cranes are moved to the end of the net rack, and a hanging point is hung on the last but one grid; and S5, the two cranes are converted into 50 cranes, and continuous moving to the net rack end is carried out. Through the method, large-span net rack structure mounting construction difficulty is reduced, the safety coefficient in the construction process is improved, construction efficiency is improved, and the construction cost is reduced.
本发明属于建筑施工技术领域，尤其是一种大跨度网架结构施工方法，针对现有技术中存在大跨度网架结构安装施工的难度高，施工过程中的安全系数低，施工效率低，施工成本高的问题，现提出如下方案，其包括S1：准备所需起重设备和工具；S2：在8‑9轴之间，从J轴向A轴首先在地面拼装上弦7格，下弦安装7格，网架此时可以起重8吨；S3：采用2台25吨吊车，然后整体提升到0.60米标高J轴网架支座位置；S4：吊车移到网架端部，吊点悬挂在倒数第二格；S5：两台吊车换成50吊车继续移到网架端部。本发明降低了大跨度网架结构安装施工的难度，提高了施工过程中的安全系数，提高了施工效率，降低了施工成本。
