Large venue steel truss construction method
The invention provides a large venue steel truss construction method which comprises the steps that S1, a steel truss is divided into a plurality of independent subareas according to the plane layout of the steel truss, and S2, four lower chord balls corresponding to a central area are installed to form a lower chord unit; s3, connecting and assembling the other two web members of the upper chord ball to form a central area unit; s4, the splicing units are gradually and outwards expanded and spliced through mutual positioning between the balls and the rods, S5, jacking equipment installation is conducted, and the meshes corresponding to the multiple subareas are synchronously in place through synchronous jacking of the multiple jacking equipment; multi-area synchronous construction is achieved by partitioning the steel net rack, the construction efficiency is improved, meanwhile, the jacking difficulty of jacking equipment is reduced, the safety in the jacking process is guaranteed, the steel net rack is supported on the string ball through the support, the supporting difficulty of the jacking equipment is reduced, and the supporting stability is guaranteed.
本发明提供一种大型场馆钢网架施工方法，包括：步骤S1，根据钢网架平面布局将钢网架分为多个独立分区，步骤S2，安装中心区对应的四个下弦球形成下弦单元；步骤S3，连接拼装上弦球的另外两根腹杆形成中心区单元；步骤S4，利用球和杆之间的相互定位逐渐向外扩展拼装各拼接单元，步骤S5，进行顶升设备安装，通过多个顶升设备同步顶升使多个分区对应的网片同步就位；通过对钢网架分区实现多区域同步施工，提高施工效率，同时降低顶升设备的顶升难度，保证顶升过程中的安全性，钢网架通过支座支撑在弦球上，降低了顶升设备的支撑难度，保证了支撑的稳定性。
