The invention discloses a beam falling prevention device, which comprises an upper plate, a lower plate, a limiting device and a damping energy dissipation device. The damping energy dissipation device comprises an arc-shaped damping rod and a T-shaped limiting head which are arranged in the longitudinal direction and the transverse direction. The limiting device comprises a first limiting seat and a second limiting seat, the first limiting seat comprises a bottom plate and a surrounding plate, and a clamping groove is formed in the edge, facing the second limiting seat, of the bottom plate; the top of the surrounding plate is fixedly connected with the bottom surface of the upper plate; the lower end of each damping rod is hinged with the lower plate; the T-shaped limiting head comprisesa head part and a neck part vertically and fixedly connected with the head part; the neck part is arranged in an area between the clamping groove of the first limiting seat and the clamping groove ofthe second limiting seat; the head part is arranged in an area between the surrounding plate of the first limiting seat and the surrounding plate of the second limiting seat;and a gap is formed between the head part and the surrounding plate. Transverse and longitudinal constraints can be established at the same time, the energy dissipation effect can be achieved in the longitudinal direction andthe transverse direction of the bridge body at the same time, and then the bridge structure is more effectively protected against earthquake damage.
本发明公开了一种防落梁装置，包括上板和下板、限位装置、阻尼耗能装置；阻尼耗能装置包括在纵向方向上和横向方向上设置的弧形阻尼杆、T形限位头；限位装置包括第一、第二限位座，第一限位座包括底板、围板，在底板上朝向第二限位座的边沿设有卡槽；围板顶部与上板底面固定连接，每一根阻尼杆下端与下板铰接；T形限位头包括头部、与头部垂直固定连接的颈部，颈部设置于第一限位座的卡槽和第二限位座的卡槽之间区域，头部设置于第一限位座的围板与第二限位座的围板之间区域，头部与围板之间设有间隙。本发明能够同时建立横向和纵向的约束，也可以在桥体纵向和横向同时发挥耗能作用，进而更有效的保护桥梁结构免受地震破坏。
