Noise-reducing durable easy-to-maintain bridge expansion joint
The invention relates to the technical field of bridge expansion joints, and provides a noise-reducing durable easy-to-maintain bridge expansion joint which comprises a first support arranged on a first bridge body, a first comb plate arranged on the first support, a first toothed plate arranged on the first support and located below the first comb plate, and a second support arranged on the first support and located below the first comb plate. The concave arc part is located on one side of the convex arc part. The sliding seat is arranged on the first support in a sliding mode, the second comb plate is arranged on the sliding seat in a lifting sliding mode, the second comb plate and the first comb plate are arranged in a staggered mode, the second comb plate is provided with an abutting part, and after the first bridge body drives the first toothed plate to move, the abutting part abuts against the convex arc part and the concave arc part in sequence and then drives one end of the second comb plate to ascend and descend. By means of the technical scheme, the problems that in the prior art, sundries and stones in comb teeth of a steel plate type expansion joint are difficult to clean, the expansion joint can be damaged due to extrusion of the stones in hot weather, and the risk that vehicles are damaged and casualties occur due to the fact that the expansion joint is likely to be collapsed when the vehicles pass by are solved.
本发明涉及桥梁伸缩缝技术领域，提出了降噪耐久易养护式桥梁伸缩缝，包括第一支座，设置在第一桥体上，第一梳板设置在第一支座上，第一齿板设置在第一支座上，位于第一梳板的下方，第一齿板具有凸弧部和凹弧部，凹弧部位于凸弧部的一侧。滑座滑动设置在第一支座上，第二梳板升降滑动设置在滑座上，第二梳板与第一梳板交错设置，第二梳板具有抵接部，第一桥体带动第一齿板移动后，抵接部先后与凸弧部和凹弧部抵接后带动第二梳板一端上升后下降。通过上述技术方案，解决了现有技术中钢板式伸缩缝梳齿中的杂物石子难以进行清洁，天气炎热时由于石子的挤压会造成伸缩缝的损坏，在车辆行驶路过时可能发生崩坏导致车辆损坏人员伤亡的风险出现的问题。
