Sound absorption cap of sound barrier
The invention discloses a sound absorption cap of a sound barrier, which comprises a pore plate, end plates, a sound absorption and insulation core, Z-shaped steel, a bracket and a steel stand column, and is characterized in that a lower buckling beam of the sound absorption and insulation core is mounted on the Z-shaped steel; the pore plate covers the sound absorption and insulation core, and the lower part of the pore plate is mounted on the Z-shaped steel; and the end plates are arranged at the two ends of the sound absorption and insulation core and fixedly connected with the top surface of the lower buckling beam of the sound absorption and insulation core and the edge of the pore plate, the bracket is welded to two flanges of the top of the steel stand column, and the Z-shaped steel is fixed to the bracket. The top diffracted sound can be effectively absorbed, the diffracted sound can be diffused and attenuated, and the noise reduction effect is remarkably improved.
一种声屏障吸声帽，包括孔板、端板、吸隔声芯、Z型钢，支托，钢立柱，其特征是吸隔声芯的下部扣梁安装在Z型钢上；孔板罩在吸隔声芯上，孔板的下部安装在Z型钢上；端板在吸隔声芯的两个端头，分别与吸隔声芯的下部扣梁顶面、孔板边连接固定，钢立柱顶部两个翼缘上焊接支托，Z型钢固定在支托上面。本发明能够有效吸收顶部绕射声，使绕射声能得到扩散和衰减，显著提高降噪效果。
