Beam falling prevention device and modular expansion joint
The invention provides a beam falling prevention device and a modular expansion joint. The beam falling prevention device comprises a sliding plate, a base, a cover plate, a limiting plate, a supporting rod and a rotating part, the supporting rod comprises a first end and a second end, the first end is connected with the rotating part, an arc-shaped groove is formed in the other end of the base, a first opening end face is formed in the end, facing the arc-shaped groove, of the base, and a first through hole is formed in the cover plate in a penetrating mode. The arc-shaped groove and the first through hole form a spherical cavity, the rotating part can rotate in the spherical cavity, a second through hole is formed in the limiting plate in a penetrating mode, the first end penetrates through the second through hole, and a gap is formed between the first end and the second through hole. The cover plate is connected with the base, and the cover plate is used for preventing the rotating part from falling off when the rotating part rotates in the spherical cavity. The anti-beam-falling device is arranged on the modular expansion joint, and when the bridge displaces, the anti-beam-falling device can better adapt to the expansion displacement of the bridge through the cooperation of the rotating part and the spherical cavity and the cooperation of the supporting rod and the second through hole.
本发明提供了一种防落梁装置及模数式伸缩缝。防落梁装置包括滑板、底座、盖板、限位板、支撑杆和转动部，所述支撑杆包括第一端和第二端，所述第一端和转动部连接，底座的另一端的内部开设弧形槽，底座朝向弧形槽的一端形成第一开口端面，盖板的内部设置贯穿的第一通孔，所述弧形槽和第一通孔形成球形空腔，转动部能够在球形空腔内部转动，限位板的内部设置贯穿的第二通孔，第一端穿过第二通孔，且第一端和第二通孔之间有间隙。盖板和底座连接，利用盖板防止转动部在球形空腔内转动时脱落。防落梁装置设置于模数式伸缩缝上，在桥梁发生位移时利用转动部和球形空腔的配合，以及支撑杆和第二通孔的配合，使防落梁装置更好的适应桥梁的伸缩位移。
