Environment-friendly sound absorption and insulation board
The invention relates to an environment-friendly sound absorption and insulation board. The environment-friendly sound absorption and insulation board comprises a sound insulation shell box and a plurality of porous sound absorption assemblies arranged in the sound insulation shell box. The sound insulation shell box comprises a profiled perforated steel plate, a profiled sound insulation steel plate, a top sealing keel and a bottom sealing keel, wherein the profiled sound insulation steel plate is parallel to the profiled perforated steel plate and arranged at an interval, and the top sealing keel and the bottom sealing keel are arranged between the profiled perforated steel plate and the profiled sound insulation steel plate. The longitudinal reinforcing keels are arranged between the profiled perforated steel plate and the profiled sound insulation steel plate, the longitudinal reinforcing keels are clamped between the top sealing keel and the bottom wall sealing keel, a plurality of silencing holes are formed in the profiled perforated steel plate in a penetrating mode, and the porous sound absorption assembly is located between every two adjacent longitudinal reinforcing keels; the porous sound absorption assembly comprises a damping sound insulation layer, sound absorption rock wool, sound absorption glass wool and glass fiber sound absorption cloth. The sound absorption and insulation structure has the advantages that better sound absorption and insulation effects are achieved in noise reduction treatment of the large factory building, the construction period is shortened, and the installation cost is reduced.
本申请涉及一种环保型吸隔声板，其包括隔声外壳盒和设置在隔声外壳盒内的若干个多孔吸声组件；隔声外壳盒包括压型穿孔钢板、与压型穿孔钢板平行且间隔设置的压型隔声钢板、设置在所述压型穿孔钢板及所述压型隔声钢板之间的顶部密封龙骨及底部密封龙骨、以及设置在压型穿孔钢板及压型隔声钢板之间的若干个纵向加强龙骨，纵向加强龙骨卡设在顶部密封龙骨和底壁密封龙骨之间，压型穿孔钢板上贯穿开设有若干个消声孔，多孔吸声组件位于相邻两个纵向加强龙骨之间；多孔吸声组件包括阻尼隔声层、吸声岩棉、吸声玻璃棉以及玻纤吸声布。本申请具有在大型厂房降噪处理中取得更好吸隔声效果的同时减少施工周期和安装成本的效果。
