Construction method of super-long cantilever cable-supported grid structure
The invention relates to the technical field of prestressed steel structure construction, and discloses a construction method of a super-long cantilever cable-supported grid structure. The method comprises the following steps that the laying position of an annular cable is determined, and an installation operation platform of a cable clamp is erected; a mounting operation platform of a radial cable is set up; the annular cables and the radial cables are paved; one end of the radial cable is connected with the cable clamp, and the other end is connected with a lifting tool; a supporting jig frame of a grid roof is arranged; the grid roof is mounted; when the grid roof is installed, a temporary cable-stayed structure is installed; the supporting jig frame of the outer ring is dismantled in sections; the cable system structure is integrally hoisted; the radial cables are integrally tensioned in a graded mode, and the grid roof is automatically separated from the supporting jig frame of the outer ring; a V-shaped supporting rod is installed; and the temporary cable-stayed structure is dismantled, the supporting jig frame is unloaded, and construction of the cable-supported grid structure is completed. According to the construction method of the super-long cantilever cable-supported grid structure, the flexible component is integrally lifted and integrally and synchronously tensioned, the construction efficiency is high, and the tensioning effect is good.
本发明涉及预应力钢结构施工技术领域，公开了一种超长悬臂索承网格结构的施工方法。本发明包括以下步骤，确定环向索的铺放位置，搭设索夹的安装操作平台；搭设径向索的安装操作平台；铺装环向索和径向索；将径向索一端与索夹连接，另一端连接提升工装；设置网格屋盖的支撑胎架；安装网格屋盖；在安装网格屋盖的同时，安装临时斜拉结构；分区段拆除外圈的支撑胎架；整体吊装索系结构；整体分级张拉径向索，网格屋盖与外圈的支撑胎架自动脱离；安装V形撑杆；拆除临时斜拉结构，并卸载支撑胎架，完成索承网格结构的施工。本发明柔性构件整体提升，整体同步张拉，施工效率高，张拉效果好。
