Expansion joint facility for relieving bumping and reducing noise
The invention discloses an expansion joint facility for relieving bumping and reducing noise, and belongs to the technical field of expansion joints. An expansion joint facility for relieving bumping and reducing noise comprises two bridge main bodies and a bridge expansion joint arranged between the two bridge main bodies, mounting grooves are formed in the adjacent sides of the two bridge main bodies, a concrete leveling layer is poured in each mounting groove, a bent steel plate is arranged at the top of each concrete leveling layer, and the bent steel plates are connected with the bridge expansion joint. An anchoring mechanism is arranged between the bending steel plate and the concrete leveling layer, and a seam covering steel plate is arranged on the top of the bridge expansion joint. The polyurethane expansion body is arranged at the top of the expansion joint to replace a comb tooth type expansion structure, so that two adjacent bridge main bodies are seamlessly connected, sundries in the expansion joint do not need to be regularly cleaned, a better buffering and damping effect can be obtained when a vehicle passes through the expansion joint, the possible vibration and bounce conditions at the expansion joint are reduced, and the service life of the expansion joint is prolonged. And noise generated by vibration when a vehicle passes through the expansion joint is effectively reduced.
本发明公开了一种缓解跳车及减噪的伸缩缝设施，属于伸缩缝技术领域。一种缓解跳车及减噪的伸缩缝设施，包括两个桥梁主体以及设置在两个桥梁主体之间的桥梁伸缩缝，两个桥梁主体相邻的一侧均开设有安装槽，每个安装槽内均浇筑有混凝土找平层，混凝土找平层的顶部设置有折弯钢板，折弯钢板与混凝土找平层之间设置有锚固机构，桥梁伸缩缝的顶部设置有盖缝钢板；本发明通过在伸缩缝的顶部设置聚氨酯伸缩体取代梳齿式伸缩结构，使相邻两个桥梁主体之间无缝连接，无需定期清理缝内杂物，可以使车辆在经过伸缩缝时能够得到更好的缓冲减震效果，减少了伸缩缝处可能会出现的震动及弹跳情况，并有效减少了车辆在经过伸缩缝时会因震动而产生的噪音。
