Beam falling prevention support
The invention discloses a beam falling prevention support. The anti-beam-falling support is suitable for limiting longitudinal displacement of a beam body when the longitudinal displacement of the beam body is too large, and comprises a limiting plate provided with a limiting hole; the fixed anchor rod is arranged in the limiting hole in a penetrating manner in a manner of reserving a movable gap in the longitudinal direction and is anchored in the pier; and the limiting plate is connected with the beam body in a penetrating manner through the positioning steel bar. According to the scheme, the fixed anchor rods are arranged in the limiting holes in the penetrating mode in the mode that the movable gaps are reserved in the longitudinal direction and anchored in the bridge pier, on one hand, the length capable of sliding during vibration of the bridge can be reserved, on the other hand, longitudinal movement of the bridge body can be effectively limited, and the bridge is prevented from falling off; meanwhile, the vertical displacement of the bridge is limited through the fixing anchor rods, and the support is further prevented from disengaging.
本申请公开了一种防落梁支座。该防落梁支座适于梁体纵向位移过大时限制梁体纵向位移，防落梁支座包括：一限位板，其开设有限位孔；一固定锚杆，以在纵向上留有活动间隙的方式穿设在限位孔内并锚固于桥墩内部；一定位钢筋，用以限位板穿接梁体。本方案中，通过将固定锚杆在纵方向上留有活动间隙的方式穿设在所述限位孔内并锚固于所述桥墩内部，一方面能留出桥梁震动可滑移长度，另一方面能有效限制梁体的纵向移动，防止桥梁发生落梁；同时，通过固定锚杆限制桥梁竖向上的位移，进一步防止支座脱空。
