Self-adaptive height-adjusting novel road and bridge butt strap connecting structure
The invention belongs to the technical field of assembly type construction of bridges, and particularly relates to a self-adaptive height-adjusting novel road and bridge butt strap connecting structure. The structure comprises a butt strap, a bridge abutment, a protective steel plate and an air column, a support is arranged on the upper end face of the bridge abutment, the two ends of the butt strap are arranged at the upper ends of the support and the air column respectively so as to be connected with a bridge body and a roadbed, the bottom of the air column is fixed to the protective steel plate through a connecting piece, and the two ends of the protective steel plate are fixedly connected with the bridge abutment and the roadbed. The two ends of the butt strap are arranged at the upperends of the bridge abutment and the air column correspondingly; the connection with a bridge body and a roadbed is realized; when the height of the roadbed is changed, the air columns can be elongated or shortened by inflating or deflating the air columns, so that the height of the butt strap is adjusted, the height difference caused by roadbed settlement and the height difference caused by laterroad repair are self-adapted, stable transition between the bridge abutment and the roadbed is guaranteed, and the phenomenon of bump of the bridge abutment is avoided.
本发明属于桥梁的装配式建造技术领域，具体涉及一种自适应调高新型路桥搭板连接结构，包括搭板、桥台、防护钢板和气柱，在所述桥台的上端面设置有支座，所述搭板的两端分别置于支座和气柱的上端，从而与桥梁体和路基连接，所述气柱的底部通过连接件固定在防护钢板上，所述防护钢板的两端分别于桥台和路基固定连接。本发明将搭板的两端分别置于桥台和气柱的上端，实现与桥梁体和路基连接，当路基高度发生变化时，本发明可以通过向气柱内充气或放气，使气柱伸长或缩短，从而实现搭板高度的调整，达到自适应由路基沉降引起的高度差以及后期道路修复引起的高度差，保证桥台与路基的平稳过渡，避免桥台跳车的现象出现。
