Building steel structure of secondary fixing anti-falling structure

ZHU YUBIN

The building steel structure of the secondary fixing anti-falling structure comprises a vertical I-shaped steel structure, and a transverse I-shaped steel structure is arranged on the side face of the concave position of the vertical I-shaped steel structure in an attached mode; the fixing steel plate is connected to the side face of the concave position of the vertical I-shaped steel structure in a welded mode, supporting steel plates are connected to the front side and the rear side of the middle of the fixing steel plate and used for fixing the transverse I-shaped steel structure through bolts, and reinforcing bases are installed on the upper side and the lower side of the fixing steel plate. According to the building steel structure of the secondary fixing anti-disengaging structure, the upper locking rod and the lower locking rod are arranged, when the upper mounting base and the lower mounting base move, the upper locking rod and the lower locking rod can synchronously penetrate through the transverse I-shaped steel structure and the reinforcing base in a staggered mode, and secondary fixing anti-disengaging is conducted on the steel structure through the upper locking rod and the lower locking rod; when the bolt for fixing the steel structure is loosened, the secondary fixing anti-falling structure can continue to lock the transverse I-shaped steel structure.

本发明公开了一种二次固定防脱结构的建筑钢结构，包括竖向工字钢结构，所述竖向工字钢结构内凹处的侧面贴合设置有横向工字钢结构；还包括：固定钢板，焊接连接在所述竖向工字钢结构内凹处的侧面，且所述固定钢板中部的前后两侧均连接有支撑钢板，用于对所述横向工字钢结构进行螺栓固定，并且所述固定钢板的上下两侧均安装有加固座。该二次固定防脱结构的建筑钢结构，设置有上锁定杆和下锁定杆，在上安装座和下安装座移动时，可同步的将上锁定杆和下锁定杆呈交错位置贯穿横向工字钢结构和加固座，利用上锁定杆和下锁定杆对钢结构进行二次固定防脱，钢结构固定的螺栓发生松动时，二次固定防脱结构可继续对横向工字钢结构进行锁定。
