Self-adaptive height difference gradual change splicing seam of spliced bridge and mounting method of self-adaptive height difference gradual change splicing seam
The invention relates to the field of bridge engineering, and discloses a self-adaptive height difference gradient splicing seam of a spliced bridge and a mounting method of the self-adaptive height difference gradient splicing seam. The telescopic joint plate is connected to the bridge surfaces of the new bridge and the old bridge, the telescopic joint plate is formed by nesting plate-shaped structures connected to the two sides of the old bridge and the new bridge, and the two nested plate-shaped structures can slide between each other, so that the telescopic joint plate can be freely extended and shortened; in addition, two ends of the telescopic joint plate are hinged to the new and old bridge surfaces through the joint plate rotating shafts and can rotate up and down. When the spliced wide bridge is put into operation and a settlement difference is generated on the bridge surfaces of the new and old bridges, no operation is needed, the height difference gradient of the new and old bridges can be automatically realized through automatic extension and inclination of the telescopic joint plate, the smoothness of the bridge surfaces is maintained, and the phenomenon of vehicle bumping at the joint is prevented, so that the method is a rapid, time-saving and labor-saving bridge reconstruction measure. The steel sliding rail, the supporting system and the supporting and heightening base are arranged, the telescopic joint plate is effectively supported, and the splicing seam structure is always kept stable integrally and is safe and reliable.
本发明涉及桥梁工程领域，公开了一种拼宽桥自适应高差渐变拼接缝及其安装方法。伸缩接缝板连接在新、老桥桥面上，伸缩接缝板由连接在老桥、新桥两侧的板状结构嵌套组成，两个嵌套的板状结构之间能滑动，以使伸缩接缝板能自由伸长、缩短；并且，伸缩接缝板两端通过接缝板转轴铰接在新、老桥桥面上，能上下转动。当拼宽桥投入运营后，新老桥桥面产生了沉降差时，本发明无需任何操作，通过伸缩接缝板自动伸长和倾斜，即可自动实现新老桥高差渐变，维持桥面平顺，防止接缝处跳车现象的发生，是一种快捷、省时、省力的桥梁改造措施。本发明设置钢滑轨、支撑系统以及支撑调高基座，对伸缩接缝板进行有效支撑，使拼接缝结构始终保持整体稳定，安全可靠。
