Grid type non-metal sound absorption unit plate
The invention relates to a grating type non-metal sound absorption unit plate which comprises a perforated panel, a sound absorption material and a back plate, the sound absorption material is arranged between the perforated panel and the back plate, the perforated panel is provided with horn-shaped holes with large outer diameters and small inner diameters, and a grating type panel is formed; a reinforcing mesh is arranged in the back plate and is formed by pouring shrinkage-compensating concrete, an expanding agent added in the shrinkage-compensating concrete is subjected to chemical reaction, and when the concrete is hardened, a certain degree of expansion is generated to counteract dry shrinkage in the hardening process and restrain cracking; the thickness of the steel bar protection layer is not less than 20mm. The sound absorption unit plate has the beneficial effects that the sound absorption unit plate is high in durability and long in service life; the overall strength is higher, and the impact resistance of the panel is higher; and the overall appearance is more attractive and elegant.
本发明涉及一种格栅型非金属吸声单元板，包括开孔面板、吸声材料和背板，所述吸声材料设置在开孔面板与背板之间，所述开孔面板上设置有大外径小内径的喇叭型开孔，形成格栅型面板；所述背板内设置钢筋网片，采用补偿收缩型混凝土浇筑而成，补偿收缩型混凝土内添加的膨胀剂发生化学反应，在混凝土硬化时产生一定程度的膨胀抵消硬化过程中的干缩，抑制开裂；钢筋保护层厚度≥20㎜。其有益效果是：该吸声单元板耐久性强，使用寿命长；整体强度更高，面板抗冲击性能更强；整体外观更加美观大方。
