Novel bridge deck expansion joint structure
A novel bridge deck expansion joint structure comprises a first rigid unit, an elastic unit, a second rigid unit and a fixing assembly, the second rigid unit is located above a bridge deck expansion joint, the first rigid unit and the elastic unit are alternately arranged in the longitudinal direction of a bridge deck to form a telescopic structure, and the second rigid unit is located in the middle of the telescopic structure, and the second rigid unit is positioned above the bridge deck expansion joint. The two fixing assemblies are located on the two sides of the telescopic structure, the fixing assemblies are fixed in the bridge floor body, and the first rigid unit, the elastic unit and the second rigid unit are clamped between the two fixing assemblies; and when the bridge deck expansion joint expands and contracts, the first rigid unit and the second rigid unit can slide back and forth on the bridge deck. According to the novel bridge deck expansion joint structure, operations such as steel bar welding and cast-in-place cement concrete are not needed, construction is more convenient, and the construction period is shorter. The rigid units and the elastic units which are arranged alternately can reduce noise, jolt and impact force on a bridge when a vehicle passes through a bridge expansion joint.
一种新型桥面伸缩缝结构，包括第一刚性单元、弹性单元、第二刚性单元和固定组件，第二刚性单元位于桥面伸缩缝上方，第一刚性单元和弹性单元沿桥面纵向交替排列成伸缩结构，第二刚性单元位于伸缩结构中部，且第二刚性单元位于桥面伸缩缝上方。两个固定组件位于伸缩结构两侧，固定组件固定在桥面主体中，第一刚性单元、弹性单元、第二刚性单元夹在两个固定组件之间；桥面伸缩缝在伸缩变化时，第一刚性单元和第二刚性单元可在桥面上来回滑动。本发明的新型桥面伸缩缝结构，不需要焊接钢筋以及现浇水泥砼等作业，施工更加便捷、施工周期更短。交替排列的刚性单元和弹性单元可降低车辆通过桥梁伸缩缝时产生的噪音、颠簸以及对桥梁的冲击力。
