Impact-resistant and anti-falling metal sound barrier
The invention belongs to the technical field of metal sound barriers, and particularly relates to an anti-impact and anti-falling metal sound barrier. The unit plate comprises a unit plate body, a plurality of rib grooves distributed in the transverse direction or the longitudinal direction are formed in a sound transmission panel and/or a back plate of the unit plate body, an elastic supporting plate is arranged between a sound absorption body located in the unit plate body and the rib grooves, and one end of the elastic supporting plate is connected with the sound absorption body through a positioning plate and rivets or bolts. A plurality of sound transmission holes are formed in the surface of the elastic supporting plate, so that noise interference is formed in cavities in the two sides of the elastic supporting plate. The novel impact-resistant anti-falling metal sound barrier bears large load impact through elastic damping buffering, the structure assembly is firm, the interior is sealed tightly, and blending noise elimination and noise reduction are long-acting and stable.
本发明属于金属声屏障技术领域，具体的讲涉及一种抗冲击防脱落金属声屏障。其包括单元板本体，单元板本体的透声面板和/或背板上设置沿横向或纵向分布的若干筋槽，位于单元板本体内部的吸声体与筋槽之间设置弹性支撑板，弹性支撑板一端通过定位板与吸声体通过铆钉或螺栓连接，其另一端通过叉手部包覆筋槽，弹性支撑板表面设置若干透声孔，使弹性支撑板两侧的空腔形成噪声干涉。该新型抗冲击防脱落金属声屏障通过弹性阻尼缓冲承受较大负载冲击、结构组装牢靠、内部封闭严密且共混消声降噪长效稳定。
