Sound barrier system comprising folded plate buckling type metal sound barrier unit plates
The invention provides a sound barrier system comprising folded plate buckling type metal sound barrier unit plates. The folded plate buckling type metal sound barrier unit plates and transparent sound insulation unit plates are inserted between adjacent H-shaped steel columns. The plate body of each folded plate buckling type metal sound barrier unit plate is of a rivet-free buckling type structure and is pressed and meshed through elastic pre-tightening force; and a sound absorption material is clamped and fixed in a closed manner through vertical support section bar lateral clamping groovesand upper and lower side plate trapezoidal clamping grooves inside. The sound barrier system can meet the requirements for lighting and sightseeing of passengers in a train, and the folded plate buckling type metal sound barrier unit plates are light in weight, good in stress, firm in fixation of the sound absorption materials, excellent in fatigue resistance, good in noise reduction effect and easy to assemble.
本发明提供一种包含折板扣合式金属声屏障单元板的声屏障系统，折板扣合式金属声屏障单元板和通透隔声单元板插设于相邻的H型钢柱之间。所述折板扣合式金属声屏障单元板板体采用无铆钉扣合式结构，通过弹性预紧力压紧咬合；内部通过竖撑型材侧向卡槽和上下侧板梯形卡槽对吸声材料实现封闭式卡装固定。本发明可满足采光和列车内旅客观光需求，所述折板扣合式金属声屏障单元板重量轻、受力好、吸声材料固定牢靠、抗疲劳性能优良、降噪效果好、装配简易。
