Assembly type flexible sound absorption and insulation screen
The invention provides an assembly type flexible sound absorption and insulation screen. The assembly type flexible sound absorption and insulation screen comprises a plurality of barrier units spliced together, and each barrier unit comprises a framework, a base and a flexible sound absorption and insulation body; and each flexible sound absorption and insulation body is formed by jointly sewing glass fiber protective cloth, a flame-retardant fiber sound absorption material and a flexible damping sound insulation material, each framework is fixed to the corresponding base, a plurality of bolt holes used for being connected with a ground structure are formed in each base, and after the barrier units are assembled, an enclosing wall structure can be defined around a construction site. According to the assembly type flexible sound absorption and insulation screen, the barrier units use combined structures of the frameworks and the flexible sound absorption and insulation bodies, compared with a solid plate structure, the screen is lighter, and even if inclination or collapse occurs, the screen does not harm personal safety; moreover, the connecting structure is easy to mount and can be detached and recycled, so that the use cost is saved; and the assembly type flexible sound absorption and insulation screen can be used indoors and outdoors, and is easy and simple to hang and assemble, the noise control comprehensive cost of the screen is low, the limitation of the appearance and the space is small, and the requirement of a special-shaped sound insulation enclosure structure can be met.
本发明提供了一种装配式柔性吸隔音屏，其包括若干拼装在一起的屏障单元，每一屏障单元均包括骨架、底座以及柔性吸隔音体。柔性吸隔音体采用玻纤防护布、阻燃纤维吸声材料及柔性阻尼隔声材料共同缝制而成。骨架固定在底座上，底座上开设有若干用于与地面结构连接的螺栓孔，屏障单元拼装后，可绕工地围成围墙结构。本发明的屏障单元采用骨架与柔性吸隔音体的组合结构，相比于实心板材结构，更加轻便，即使发生歪斜或倒塌，也不会对人身安全构成危害。并且，连接结构易安装，可拆卸回收利用，节省了使用成本。可室内外使用，悬挂组装，轻松简单。其噪声治理综合成本低，受外形、空间限制小，可满足异型隔声围护结构。
