The invention discloses a noise reduction device for roads and bridges. The noise reduction device comprises a plurality of noise reduction assemblies arranged left and right at intervals, each noisereduction assembly comprises a fixing plate body, a plurality of springs are fixedly connected to the rear side wall of each fixing plate body and distributed on the corresponding fixing plate body ina rectangular array mode, each noise reduction assembly further comprises a noise reduction plate, each noise reduction plate is fixedly connected to the corresponding multiple springs, a plurality of damping corrugations are fixedly connected to each noise reduction plate, a damping groove is formed between every two adjacent damping corrugations, the noise reduction assemblies are hinged through hinge pieces, the hinge pieces comprise a connecting rod fixedly connected to the top of the fixing plate body in the middle, and the left end and the right end of the connecting rod are rotationally connected with the tops of the parts, adjacent thereto, of the fixing plate bodies through fixing pins. By means of the device component design, noise can be effectively reduced, operation is convenient, and the noise reduction performance is good.
本发明公开道路桥梁用降噪装置，包括若干个左、右间隔设置的降噪组件；降噪组件均包括固定板体，所述固定板体的后侧壁固定连接有若干个弹簧，若干个所述弹簧在固定板体上呈矩形阵列分布；所述降噪组件还包括降噪板，所述降噪板固定连接在若干个所述弹簧上；所述降噪板上固定连接有若干个阻尼瓦楞，相邻所述阻尼瓦楞之间形成阻尼槽；所述降噪组件之间通过铰接件铰接；所述铰接件包括固定连接在位于中间部位所述固定板体顶部的连接杆，所述连接杆的左右两端均通过固定销轴转动连接相邻部位所述固定板体的顶部。上述装置部件设计，能够有效的减低噪音，且操作方便，降噪性能较佳。
