The invention discloses a anti-beam-falling expansion joint device which comprises a fixed plate and a joint crossing movable plate which are oppositely arranged, a plurality of first comb teeth are arranged at the inner end of the fixed plate, a plurality of second comb teeth are arranged at the inner end of the joint crossing movable plate, and the first comb teeth and the second comb teeth are arranged at intervals in a staggered mode. A widened first comb tooth head is arranged at the top end of each first comb tooth, and a widened second comb tooth head is arranged at the top end of each second comb tooth; the width of each second comb tooth head is larger than the gap between every two adjacent first comb tooth heads. According to the anti-beam-falling expansion joint device and the working method thereof, during an earthquake, the displacement of the beam end of a bridge can be limited, the beam end cannot be separated at the expansion joint position, beam falling of the beam end is prevented, and the safety performance is improved.
本发明公开了一种防落梁伸缩缝装置，包括相对设置的固定板和跨缝活动板，所述固定板内端设置多个第一梳齿，所述跨缝活动板内端设置多个第二梳齿，所述第一梳齿和第二梳齿交错间隔排布，所述第一梳齿的顶端设置有增宽的第一梳齿头，所述第二梳齿的顶端设置有增宽的第二梳齿头；所述第二梳齿头的宽度大于两个相邻所述第一梳齿头之间的间隙。本发明防落梁伸缩缝装置及其工作方法，地震时能够限定桥梁梁端位移，梁端在伸缩缝位置不会分离，防止梁端落梁，提高了安全性能。
