Clamping groove-type sound absorption plate
The invention discloses a clamping groove-type sound absorption plate. The sound absorption plate comprises an inner plate facing a sound resource and an outer plate which is attached to the inner plate in a U-shaped mode, the connection between the outer plate and the upper part of the inner plate is a groove surface, the connection between the outer plate and the lower part of the inner plate isa boss surface, a horizontal trapezoidal groove is formed in the groove surface, and a trapezoidal boss corresponding to the trapezoidal groove is arranged on the boss surface; a plurality of louverstructures are arranged on the inner plate; and a centrifugal glass plate is filled between the inner plate and the outer plate. According to the clamping groove-type sound absorption plate, a clamping groove structure is adopted, the sealing effect is good, and installation is convenient; and the louver structures are adopted, good sound absorption efficiency is achieved, and thus the sound insulation capacity of the sound absorption plate is greater than 35 dB.
本发明公开了一种卡槽式吸声板，所述的吸声板包括面向声源的内板，以及呈U字形贴合于内板的外板，所述外板与内板上部的连接处为凹槽面，外板与与内板下部的连接处为凸台面，所述的凹槽面设有一水平的梯形凹槽，所述的凸台面设有与梯形凹槽相对应的梯形凸台；所述的内板上设有若干列百叶窗结构；所述的内板与外板之间填充有离心玻璃板。本发明中，采用卡槽结构，密封效果好，安装便捷；采用百叶窗结构，获得了较佳的吸声效率，使得吸声板的隔音量大于35dB。
