Novel sound barrier unit plate
The invention belongs to the technical field of sound barriers, and particularly relates to a novel sound barrier unit plate which is particularly suitable for pulse wind pressure occasions and movable displacement structures. The novel sound barrier unit plate comprises a shell and a sound absorber arranged in the shell, an elastic piece is arranged between a side plate of the shell and a profile steel stand column, and the elastic piece comprises one or more metal springs, metal elastic pieces, rubber elastomers or air springs which are arranged on the side plate; the novel sound barrier unit plate can effectively resist pulse wind pressure load, has a buffering displacement effect, and can be widely applied to special structures such as bridge expansion joints and the like.
本发明属于声屏障技术领域，具体的讲涉及一种新型声屏障单元板，特别适用于脉冲风压场合以及移动变位结构。该新型声屏障单元板包括外壳以及设置在外壳内的吸声体，外壳的侧板与型钢立柱之间设置弹性件，弹性件包括设置在侧板上的一个或多个金属弹簧、金属弹片、橡胶弹性体或空气弹簧；该新型声屏障单元板能够有效对抗脉冲风压负载，具有缓冲变位效果，可以广泛地应用在桥梁伸缩缝等特殊结构处。
