Detachable subway station roof anti-collapse inhaul cable structure and construction method
The invention discloses a detachable subway station roof anti-collapse inhaul cable structure and a construction method. The detachable subway station roof anti-collapse inhaul cable structure comprises a plurality of inhaul cables; the plurality of inhaul cables extending in the width direction of a subway station are arranged in the length direction of the subway station; the two ends of the inhaul cables are fixed through fixed supports; pre-embedded steel plates are arranged in the fixed supports, rabbets are reserved in the fixed supports, and the corresponding inhaul cables are fixed and straightened through adjustable fixed ends of the pre-embedded steel plates; horizontal additional steel bars and vertical additional steel bars are arranged in the fixed supports; the horizontal additional steel bars extend into the side walls of the subway station and are fixed to the side walls; the vertical additional steel bars extend into a roof of the subway station and are fixed with the roof; and the embedded steel plates are provided with anchor bars. During construction, the fixed supports are firstly constructed, and then the inhaul cables are installed; and when the inhaul cables are loosened or damaged, the inhaul cables are straightened or disassembled by adjusting the adjustable fixed ends by removing the anti-corrosion material, and then the rabbets are filled with the anti-corrosion material. According to the detachable subway station roof anti-collapse inhaul cable structure and the construction method, and large-area casualties of personnel in the station caused by large-area collapse of the roof during an earthquake are avoided.
本发明公开了可拆卸式地铁车站顶板防倒塌拉索结构及施工方法，包括若干拉索；沿地铁车站的长度方向设置若干沿地铁车站的宽度方向延伸的拉索；拉索的两端通过固定支座固定；固定支座内设有预埋钢板并预留企口，通过预埋钢板的可调节固定端固定并拉直相应的拉索；固定支座内设有水平附加钢筋和竖向附加钢筋；水平附加钢筋延伸入地铁车站的侧墙，与侧墙固定；竖向附加钢筋延伸入地铁车站的顶板，与顶板固定；预埋钢板设有锚筋。施工时，先施工固定支座，然后安装拉索；当拉索发生松弛或损毁时，通过清除防腐材料，调整可调节固定端将拉索绷直或拆卸后，再填充反腐材料。本发明确保地震时，顶板不会大面积坍塌造成车站内人员大面积伤亡。
