Sound absorption structure of sound barrier and novel closed sound barrier
The invention belongs to the technical field of sound barriers, particularly relates to a sound absorption structure of a sound barrier, and is particularly suitable for a railway bridge sound barrier. The sound absorption structure of the sound barrier comprises cross beams arranged side by side in the longitudinal direction and sound barrier unit plates arranged between the cross beams, supports are arranged on the upper end faces and the lower end faces of the cross beams respectively, back plates and face plates of the unit plates adjacent in the longitudinal direction are connected in a clamped mode through the supports respectively, the sections of the supports are in an I shape, and bottom plates of the supports are connected with the cross beams. Fist-clenching parts are arranged on the two sides of a top plate of the unit plate respectively, fist-holding parts are arranged on the edges of a back plate and a face plate of the unit plate respectively, the fist-holding parts and the fist-clenching parts are matched to form a clamping mechanism, and a buckle cover used for wrapping and fixing the clamping mechanism is arranged on the upper portion of the top plate of the support. The sound absorption structure of the barrier is convenient to manufacture and install and excellent in sound absorption and insulation performance, the top face of the sound barrier is smooth through hidden clamping connection, and the problems of sound leakage and rain seepage are avoided.
本发明属于声屏障技术领域，具体的讲涉及一种声屏障的吸声结构，尤其适用于铁路桥梁声屏障。该声屏障的吸声结构包括沿纵向并排的横梁以及设置在横梁之间的声屏障单元板，横梁的上端面、下端面分别设有支座，沿纵向相邻的单元板背板和面板分别通过支座卡合连接，支座的截面呈工形，其底板与横梁连接，其顶板两侧分别设有握拳部，单元板的背板和面板的边沿分别设有抱拳部，抱拳部与握拳部配合形成卡合机构，支座的顶板上部设有用于包覆固定卡合机构的扣盖；该屏障的吸声结构制造安装便捷、吸隔声性能优异，其通过隐藏式卡合连接，使声屏障顶面平整，避免漏声渗雨问题。
