Prefabricated assembled bridge continuous seam structure and construction method thereof
The invention discloses a prefabricated assembled bridge continuous seam structure and a construction method thereof.The prefabricated assembled bridge continuous seam structure comprises prefabricated beam bodies, first connecting plates and U-shaped telescopic pieces, the first connecting plates and the U-shaped telescopic pieces are arranged in mounting grooves of the adjacent prefabricated beam bodies, the two ends of each first connecting plate and the side wall of the corresponding mounting groove are arranged at intervals, inserting seams are formed, and the telescopic pieces are arranged in the inserting seams in an inverted-U shape; by means of the telescopic part arranged in the inverted-U shape, when small displacement or deformation is generated between the prefabricated beam bodies, the telescopic part can be extruded, energy consumption is completed through movement of the two supporting arms of the telescopic part, then the stability of the prefabricated beam bodies is guaranteed, the structure is simple, and mounting and dismounting are easy; the arrangement of the first connecting plates ensures the continuity between the precast beam bodies, the GD elastic concrete connecting layers arranged on the connecting plates are matched with the telescopic movement of the telescopic pieces, the adjacent asphalt layers cannot be pulled, and then the stability of the asphalt concrete of the surface layer is ensured.
本发明公开了一种预制拼装桥梁连续缝结构及其施工方法，包括预制梁体、设置在相邻预制梁体安装槽内的第一连接板和U型伸缩件，第一连接板的两端与安装槽侧壁之间均间隔设置并形成插接缝，伸缩件成倒U型设置在插接缝内；本发明通过倒U型设置的伸缩件，当预制梁体之间产生微小位移或者形变时，会对伸缩件造成挤压并通过伸缩件的两条支臂的移动来完成耗能，进而保证预制梁体的稳定性，结构简单，易于安装拆卸，此外，第一连接板的设置保证了预制梁体之间的连续性，设置在连接板上的GD弹性混凝土连接层配合伸缩件的伸缩移动，并不会对相邻的沥青层产生拉扯作用，进而保证了面层沥青混凝土的稳定性。
