The invention relates to the technical field of bridge expansion joints, in particular to a modular anti-beam-falling expansion joint device and a mounting method.The modular anti-beam-falling expansion joint device comprises two pieces of F-section expansion joint profile steel, a plurality of connecting shafts and a plurality of expansion assemblies, the two pieces of F-section expansion joint profile steel are each provided with a plurality of through holes, and the two ends of each connecting shaft penetrate through the corresponding through holes correspondingly; the telescopic assembly comprises a box body, a first rubber buffering soft block, a plurality of damping rods, an energy absorption block and a limiting block, the box body is fixedly connected with the corresponding F-section expansion joint profile steel, when an earthquake occurs, the two F-section expansion joint profile steel moves along the connecting shaft, and when the F-section expansion joint profile steel makes contact with the first rubber buffering soft block, buffering is conducted, and the energy absorption block is fixedly connected with the limiting block. And after the first rubber buffer soft block reaches the limit, the damping rod can be driven to contract and absorb shock, and finally, the damping rod collides with the energy absorption block to absorb kinetic energy after reaching the limit, so that the buffer and shock absorption effect can be effectively improved, the buffer structure is prevented from being damaged, and the use safety is improved.
本发明涉及桥梁伸缩缝技术领域，具体涉及一种模数式防落梁伸缩缝装置及安装方法，包括两个F截面伸缩缝型钢、多个连接轴和多个伸缩组件，两个F截面伸缩缝型钢均具有多个通孔，多个连接轴的两端分别贯穿对应的通孔，伸缩组件包括箱体、第一橡胶缓冲软块、多个阻尼减震杆、吸能块和限位块，箱体与对应的F截面伸缩缝型钢固定连接，当地震发生时，两个F截面伸缩缝型钢沿连接轴移动，当F截面伸缩缝型钢与第一橡胶缓冲软块接触后，进行缓冲，待第一橡胶缓冲软块到达极限后，可带动阻尼减震杆收缩，进行减震，最后阻尼减震杆到达极限后与吸能块碰撞，吸收动能，由此可有效提高缓冲减震的效果，避免缓冲结构损坏，提高使用安全性。
