Displacement device for highway bridge plate-type expansion joint
The invention discloses a displacement device for a highway bridge plate-type expansion joint. The displacement device is composed of an upper part, a middle part and a lower part, wherein the upper part is composed of side beams and a middle beam, the middle part is a sliding pressing control system, the lower part is a supporting slide way, the upper part and the middle part are combined together in a welding mode, and the middle part and the lower part are combined together in a bolt pressing mode. A plurality of sliding faces are adopted, multi-direction movement of all the beams is guaranteed, the displacement uniformity of all the beams can be adjusted through the horizontally-installed control springs during displacement. Due to the fact that an integrated structure is adopted, multi-point supporting is achieved, the force transmission effect is good, the structure is stable, and the service life is long. According to the actual telescopic displacement of the bridge, the designrequirement can be met by increasing or decreasing the number of the middle beams, the leave-factory seam width can be adjusted through the control springs and the locking screws embedded between theprofile steel, and parameter adjustment during production, machining and installation is greatly facilitated.
本发明公开了一种用于公路桥梁板式伸缩缝的位移装置，由上中下三个部分组成，上部由边梁和中梁组成，中部为滑移压紧控制系统，下部为支撑滑道，上中部采用焊接方式组合在一起，中下部采用螺栓压紧方式组合在一起。本发明采用了多个滑动面，保证了各梁的多方向移动，位移时可通过水平安装的控制弹簧调节各梁位移均匀性，由于该发明采用整体式结构，多点支撑，传力效果好，结构稳定，具有较长的使用寿命。根据桥梁的实际伸缩位移量，本发明可通过增减中梁数量满足设计需要，可通过嵌在各型钢间的控制弹簧和锁紧螺杆调节出厂缝宽，极大方便生产加工和安装时的参数调整。
