Large-span spatial special-shaped steel structure roof and construction method thereof
The invention relates to a large-span space special-shaped steel structure roof, a translation system between a lower steel structure and a roof cover comprises a guide rail fixedly connected to the top of the lower steel structure, a plurality of sliding mechanisms for supporting the roof cover are arranged at the top of the guide rail, and a straining beam is fixed between two mounting seats in a connecting mechanism between every two adjacent sliding mechanisms; a penetrating two-way threaded rod is rotationally connected between the two sides of the straining beam, the circumference of the two-way threaded rod is in threaded connection with two symmetrically-arranged second sliding bases, the tops of the second sliding bases slidably penetrate through the top of the straining beam, the tops of the two second sliding bases are rotationally connected with ejector rods, and the tops of the two ejector rods are rotationally connected with the same supporting plate; a hydraulic driving mechanism for driving the roof cover to move is arranged on the guide rails; the problems that at present, flexibility of local supporting of a special-shaped roof body is poor, deformation is large due to the fact that a local position lacks of supporting during integral sliding construction of a roof structure body, and follow-up construction quality is affected are solved.
本发明涉及一种大跨空间异形钢结构屋盖，下钢结构和屋顶盖之间的平移系统包括固定连接在下钢结构顶部的导轨，导轨的顶部设有多个对屋顶盖支撑用的滑动机构，相邻两个滑动机构之间连接机构中两个安装座之间固定有拉梁，拉梁的两侧之间转动连接有贯穿的双向螺纹杆，双向螺纹杆的圆周螺纹连接有两个对称设置的第二滑动座，第二滑动座的顶部滑动贯穿拉梁的顶部，两个第二滑动座的顶部均转动连接有顶杆，两个顶杆的顶部转动连接有同一个支撑板；导轨上设置有驱动屋顶盖移动的液压驱动机构；解决目前存在对异型屋盖本体局部支撑的灵活性较差，屋盖结构本体整体滑动施工时，由于局部位置缺少支撑造成变形大，影响后续施工质量的问题。
