Large-span cantilever steel structure stair installation structure
The invention discloses a large-span overhanging steel structure stair installation structure which comprises a top inhaul cable anchor plate mechanism, a bottom stair anchor cable mechanism and an anchor cable arranged between the inhaul cable anchor plate mechanism and the bottom stair anchor cable mechanism, wherein the top inhaul cable anchor plate mechanism and the bottom stair anchor cable mechanism are installed in cooperation with a roof truss. The bottom stair anchor cable mechanism is installed in cooperation with a steel structure stair, and the bottom stair anchor cable mechanism can adjust the anchor cable installation length between the inhaul cable anchor plate mechanism and the bottom stair anchor cable mechanism. According to the stair installation structure in the technical scheme, the top inhaul cable anchor plate mechanism is matched with the installed truss on the roof for installation, the truss serves as a stress point, compared with a traditional inclined supporting mode, use of supporting columns and supporting frames can be greatly reduced, and the situation that the construction space is insufficient is avoided; and meanwhile, the anchor cable is matched with the bottom stair anchor cable mechanism to pull the overhanging end of the stair, stair construction is facilitated, after the bottom stair anchor cable mechanism adjusts the length of the inhaul cable to the proper length, the inhaul cable is in the state that the inhaul cable is pulled tighter and tighter, and the overall construction structure is more reliable.
本发明公开了一种大跨度悬挑钢结构楼梯安装构造，包括配合屋面桁架安装的顶部拉索锚板机构、底部楼梯锚索机构以及设置于拉索锚板机构和底部楼梯锚索机构之间的锚索；底部楼梯锚索机构配合钢结构楼梯安装，底部楼梯锚索机构可调节拉索锚板机构和底部楼梯锚索机构之间的锚索安装长度；本技术方案的楼梯安装构造，通过顶部拉索锚板机构配合屋面已经安装好的桁架进行安装，桁架作为受力点，相对于传统斜向支撑的方式可极大减少支撑柱以及支撑架的使用，避免施工空间不足的情况，同时锚索配合底部楼梯锚索机构将楼梯悬挑端拉住，便于楼梯施工，底部楼梯锚索机构调节拉索长度到合适长度后，使得拉索处于越拉越紧的状态，整体施工结构更加可靠。
