Mounting method of steel structure branch supporting turning large-span aluminum alloy reticulated shell bay tent
The invention discloses an installation method of a steel structure branch support turning large-span aluminum alloy reticulated shell bay tent, which comprises the following steps of: assembling a space truss forming steel frame platform on the ground, arranging rigid support limiting pieces on the space truss forming steel frame platform according to positioning points on the inner side of an external corner arc-shaped aluminum material, and fixing the steel structure branch support turning large-span aluminum alloy reticulated shell bay tent to the external corner arc-shaped aluminum material; and the reticulated shell at the arc-shaped part of the external corner and the reticulated shell at the plane area are mounted through the rigid support limiting piece and are assembled on the ground. And then the vertical face aluminum alloy latticed shell is assembled and lifted one by one through a lifting device. Finally, a branch steel structure is installed, at the supporting position of the branch steel structure, area net rack loads need to be transmitted to the branch steel structure through special joints connected with the branch structure, the branch steel structure is a long and thin component, can only bear axial force and cannot bear bending moment, and in other words, the center of the branch axis must pass through the center of a bottom disc. The special rivets connected with the I-shaped aluminum flanges occupy most of the area of the disc, and the lug plates connected with the steel forks are unique in angle and unfavorable in stress, so that a steering and direction-adjusting platform is additionally arranged on the joint, assembly is convenient, installation is rapid and economical, and the curtain wall form is smooth.
本发明公开了一种钢构枝杈支撑转折大跨铝合金网壳飘篷的安装方法，步骤如下：在地面组装空间成榀钢架平台，根据阳角弧形铝材内侧定位点，在空间成榀钢架平台设置刚性支撑限位件，通过刚性支撑限位件安装阳角弧形部位的网壳及平面区域的网壳，在地面组装。接着组装立面铝合金网壳，通过提升装置逐榀提升。最后安装枝杈钢构，在其支撑位置，因区域网架荷载需要通过枝杈结构连接的特殊节点传递至枝杈钢构，又枝杈钢构是细长构件，只能承受轴向力，不能承担弯矩，即树杈轴线中心必须通过底部圆盘的中心。而与工字型铝材翼缘连接的特制铆钉占据圆盘上大部分面积，与钢构树杈连接的耳板的角度唯一，受力不利，故对此节点增设转向调向平台，组装方便、安装快捷、经济，幕墙形式流畅。
