Highway bridge expansion joint structure and maintenance, reinforcement and construction method
The invention relates to the technical field of bridge expansion joints, in particular to a highway bridge expansion joint structure and a maintenance, reinforcement and construction method.The highway bridge expansion joint structure comprises a roadbed layer, two expansion preformed grooves are formed in the upper portion of the roadbed layer, embedded steel bars are arranged in the two expansion preformed grooves, and the outer portions of the embedded steel bars are filled with concrete filling layers; the device further comprises a frame body, and the frame body is arranged in the telescopic reserved groove. The displacement assemblies are arranged in the telescopic reserved grooves in parallel; the reinforcing assembly is arranged in the connecting steel bar, and the exterior of the connecting steel bar can be fixed through the reinforcing assembly, so that when the connecting steel bar is used, the connecting steel bar cannot extrude the concrete filling layer when being extruded, and the situation that the part, for fixing the connecting steel bar, of the concrete filling layer is damaged is avoided; the supporting effect of the connecting steel bars is improved, the situation that the boundary beam assembly inclines is prevented, and the butt joint effect of the first comb plate and the second comb plate above the boundary beam assembly is improved.
本发明涉及桥梁伸缩缝技术领域，具体是一种公路桥梁伸缩缝结构及维修加固及施工方法，包括路基层，所述路基层上方开设有两个伸缩预留槽，两个所述伸缩预留槽内均设置有预埋钢筋，所述预埋钢筋的外部填充有混凝土填充层，还包括有架体，所述架体设置在伸缩预留槽内；位移组件，所述位移组件呈平行状设置在伸缩预留槽内；本发明内部设置有加固组件，通过加固组件能够将连接钢筋的外部固定住，这样连接钢筋在使用的时候，连接钢筋能够受到挤压的时候不会对混凝土填充层造成挤压，避免混凝土填充层固定连接钢筋的部位出现损坏的情况，提高连接钢筋的支撑效果，防止边梁组件出现歪斜的情况，提高边梁组件上方梳齿板一和梳齿板二的对接效果。
