Comb plate expansion joint anti-loosening structure and construction method
The invention relates to a comb tooth plate expansion joint anti-loosening structure and a construction method, the structure comprises a comb tooth steel plate, a sleeve and a bolt, the comb tooth steel plate is anchored with expansion joint anchoring concrete through the sleeve and the bolt, the sleeve is anchored in the expansion joint anchoring concrete, the bolt penetrates through a through hole in the comb tooth steel plate to be in threaded connection with the sleeve, and the comb tooth steel plate is in threaded connection with the bolt. The sleeves are connected with planting steel bars implanted into beam top concrete in a double-face welding mode, and the sleeves are connected into a whole through sleeve connecting steel bars and distribution steel bars. According to the structure, the special sleeve bolt is adopted for anchoring the comb plate, the thread meshing height and the overall stress performance of the structure are increased, and the anchoring performance of a fastener is improved; and meanwhile, the buffer contact surface is additionally arranged, so that the driving load is uniformly distributed, and the impact effect of vehicle driving on the toothed plate is reduced, thereby effectively avoiding the occurrence of fastener loosening and being beneficial to normal passing of the expressway.
本发明涉及一种梳齿板伸缩缝防松构造及施工方法，该构造包括梳齿钢板、套筒及螺栓，所述梳齿钢板采用套筒和螺栓与伸缩缝锚固混凝土锚固，其中，套筒锚固在伸缩缝锚固混凝土中，螺栓穿过梳齿钢板上通孔与套筒螺纹连接，套筒采用双面焊连接植入梁顶混凝土中的种植钢筋，套筒之间则通过套筒连接钢筋和分布钢筋连成整体。该构造采用专用套筒螺栓对梳齿板进行锚固，增大了丝牙咬合高度和结构整体受力性能，提升了紧固件的锚固性能；同时增设了缓冲接触面，确保行车荷载得以均匀分布，降低了车辆行驶对齿板的冲击效应，从而有效规避紧固件松动情形的发生，有利于高速公路的正常通行。
