Multidirectional displacement composite plate type telescopic device for highway bridge
The invention discloses a multidirectional displacement composite plate type telescopic device composed of a displacement device and a fixing plate, wherein one end of the fixing plate is welded to the upper surface of an inner boundary beam of the displacement device in a flush mode; a force transmission fulcrum is formed on the inner side of the fixing plate through a supporting block; a polytetrafluoroethylene plate on the upper surface of the supporting block and the fixing plate form a sliding supporting point; the other side of the fixing plate is connected with a bridge floor through bolts on an anchoring assembly; the anchoring assembly is composed of an anchoring box body, a pressing rubber block and connecting bolts; the fixing plate is embedded into the anchoring box body through a boss at the bottom; and the bottom of the boss and the pressing rubber block form pre-tightening force when the bolts are fastened. The displacement device is composed of beam bodies, connecting frames, pressing beams, pressing supports, slideways and pressing bolts, the side beams and the middle beam are pressed on the slideway through the connecting frames and the pressing supports of the side beams and the middle beam, the beams slide through a sliding face formed by the pressing supports, the contact faces of the pressing beams and the slideway, and the telescopic displacement requirement is met.
本发明公开了一种公路桥梁用多向位移复合板式伸缩装置，由位移装置和固定板组成，固定板一端与位移装置内边梁上表面平齐焊接，内侧由支撑块形成传力支点，支撑块上表面的四氟板与固定板形成滑动支撑点；固定板另一侧与桥面通过锚固组件上的螺栓连接，锚固组件由锚固箱体、压紧橡胶块和连接螺栓组成，固定板通过底部的凸台嵌入锚固箱体，凸台底部与压紧橡胶块在螺栓紧固时形成预紧力。位移装置由梁体、连接架、压紧梁、压紧支撑、滑道及压紧螺栓组成，边梁和中梁分别通过各自的连接架、压紧支撑由压紧梁两端的螺栓压紧在滑道上，各梁通过压紧支撑与压紧梁和滑道接触面形成的滑移面滑动，满足伸缩位移要求。
