Construction method of annular cable-supported grid structure with upper grid participating in balancing inhaul cable pretension
The invention discloses a construction method of an annular cable-supported grid structure with an upper grid participating in balancing inhaul cable pretension. The construction method comprises thefollowing construction steps of (1) mounting a column and an outer ring; (2) installing a jig frame capable of being pressed and pulled below a main grid, and arranging a horizontal sliding device onthe top of the jig frame; (3) mounting the main grid and corresponding supporting rods on the jig frame, wherein the jig frame is pressed at the moment; (4) mounting and tensioning a lower cable net,wherein the jig frame is pulled, and the top end of the jig frame horizontally slides relative to the main grid; (5) mounting cantilever grids and corresponding supporting rods; and (6) finally dismounting the jig frame after mounting a part or all of a roof system. According to the construction method, the jig frame does not need to be arranged below the overhanging grids, and ring cable spreading and lifting installation are facilitated; the jig frame capable of being pressed and pulled is arranged to maintain the elevation of the main grid when an inhaul cable is tensioned, and the mountingprecision of the cantilever grids is controlled; and the construction method conforms to the mechanical property of the cable-supported grid structure with the upper grid participating in balancing inhaul cable pretension, and efficient and high-precision construction forming is facilitated.
本发明公开了一种上部网格参与平衡拉索预拉力的环形索承网格结构的施工方法。本发明施工步骤为：①首先安装柱子和外环；②然后在主网格下安装可受压和拉的胎架，胎架顶设水平滑移装置；③然后在胎架上安装主网格和相应撑杆，此时胎架受压；④然后安装和张拉下部索网，此时胎架受拉且顶端与主网格有水平相对滑移；⑤然后安装悬挑网格和相应撑杆；⑥最后安装部分或全部屋面系统后卸除胎架。该施工方法无需在悬挑网格下设置胎架，便于环索铺展和提升安装；设置可受压和拉的胎架来维持拉索张拉时主网格标高，有利于控制悬挑网格安装精度；该施工方法符合上部网格参与平衡拉索预拉力的索承网格结构的力学特性，且有利于高效和高精度的施工成型。
