Riding double-cylinder flat-rotation multidirectional displacement comb-tooth-shaped telescopic device
The invention discloses a perforation double-brief flat-turning multidirectional displacement comb-shaped expansion device which is characterized in that the comb-shaped expansion device is composed of two movable comb plates, a sliding plate and a water stop belt, one movable comb plate is arranged on the sliding plate, the movable comb plate and a rubber support are anchored on a beam body on one side through an anti-loosening bolt, and the other movable comb plate and the rubber support are anchored on a beam body on the other side through an anti-loosening bolt. The other movable comb plate is arranged on the sliding plate and is anchored on the beam body on the other side by the anchoring bolt; comb teeth of the two movable comb plates are mutually inserted and are arranged on the corresponding sliding plates B across the expansion joints in a sliding connection manner. Compared with the prior art, the rubber waterstop has the multidirectional displacement functions of longitudinal displacement, vertical rotation, plane rotation and the like, the rigidity is doubled due to stress of a double-simple structure, stones and sundries on comb teeth can be effectively prevented from falling into the rubber waterstop, and the service life of the rubber waterstop is prolonged. The technical problem that a perforation unit type multi-directional displacement comb-shaped telescopic device is poor in dust prevention performance is well solved, and the multi-directional displacement comb-shaped telescopic device is particularly suitable for being used on urban elevated projects and advanced bridges.
本发明公开了一种骑缝双简平转多向变位梳齿形伸缩装置，其特点是梳齿形伸缩装置由两活动梳齿板与滑板和止水带组成，所述一活动梳齿板设置在滑板上，且由防松螺栓将其与橡胶支座锚固在一侧的梁体上，另一活动梳齿板设置在滑板上，且由锚固螺栓将其锚固在另一侧的梁体上；所述两活动梳齿板的梳齿相互承插，且跨伸缩缝设置在对应的B滑板上为滑动连接。本发明与现有技术相比具有纵向位移、竖向转动和平面转动等多向变位功能，而且双简式结构受力，刚度提高一倍，并能有效阻止梳齿上的石头、杂物跌落到橡胶止水带内，较好的解决了骑缝式单元式多向变位梳齿形伸缩装置的防尘性差的技术难题，尤其适和城市高架工程和高级桥梁上使用。
