Wall body unit of sound insulation wall, sound insulation wall and sound insulation wall system
The invention provides a wall body unit of a sound insulation wall. The wall body unit comprises at least two sound insulation plates, and a sound insulation assembly is arranged between every two adjacent sound insulation plates; a sound insulation cavity is formed between the sound insulation plate and the sound insulation assembly; the sound insulation assembly comprises a connecting piece, and the connecting piece is provided with a sound absorption enhancing piece used for enhancing sound absorption. The holes are formed in the connecting piece, so that the sound insulation cavity can be prevented from being sealed, the opportunity of outward scattering and leakage of sound waves from the sound insulation cavity is increased, accumulation of the sound waves in the cavity is reduced, the amplification effect is weakened, the contact area between a sound insulation material in the sound insulation cavity and a sound source can be increased by arranging the hole structure, and the sound insulation effect is improved. The sound insulation material can absorb more sound energy, so that the intensity of sound transmitted into the cavity is weakened, and the horn effect is relieved. The structure is simple, machining is convenient, and the good sound insulation effect can be achieved.
本发明提供一种隔音墙的墙体单元，包括至少两块隔音板，相邻两块所述隔音板之间设置有隔音组件；所述隔音板与所述隔音组件之间形成隔音腔；所述隔音组件包括连接件，所述连接件设置有用于增强吸音的吸音增强件。本发明在所述连接件上设置孔洞可以避免所述隔音腔密封，增加了声波从所述隔音腔向外散射和泄露的机会,减少了声波在空腔内的累积,使放大效果减弱，并且设置孔洞结构还可以增加所述隔音腔中的隔音材料与声源之间的接触面积,这有利于隔音材料吸收更多的声能,从而减弱传播到空腔内的声音强度,减轻“喇叭效应”。这种结构简单，加工方便，且能实现良好的隔音效果。
