Sound insulation flitch for existing wall and mounting method of sound insulation flitch

The invention provides a sound insulation flitch for a wall and an installation method thereof.The sound insulation flitch for the wall can enhance the sound insulation effect of the indoor existing wall, the sound insulation flitch for the wall comprises a bottom plate, an adhesive layer is arranged at the bottom of the bottom plate, a soft supporting frame is arranged at the top of the bottom plate, and a sound insulation plate is arranged at the top of the soft supporting frame; a decorative surface layer is arranged on the top of the sound insulation plate, the soft supporting frame is filled with sound absorption cotton, and the bottom plate, the soft supporting frame, the sound insulation plate and the decorative surface layer are fixedly bonded through adhesives. The sound insulation flitch provided by the invention aims to solve the problems that in the prior art, a sound insulation wall cannot be conveniently constructed and reused, and sound insulation cotton is poor in effect, and is based on the principle that a soft material sound bridge with low dynamic elastic modulus is weak in sound transmission effect and an air layer is sound-proof; the sound insulation flitch for the indoor existing wall is convenient to construct, easy to cut and assemble, reusable, simple in structure and capable of effectively enhancing the sound insulation effect of the wall.

本发明提供一种增强室内即有墙壁隔音效果的墙壁用隔音贴板及其安装方法，该墙壁用隔音贴板，包括底板，所述底板的底部设置有胶黏层，所述底板的顶部设置有软质支撑框架，所述软质支撑框架的顶部设置有隔音板，所述隔音板的顶部设置有装饰面层，软质支撑框架的内部充填有吸音棉，所述底板、软质支撑框架、隔音板、装饰面层之间均通过粘接剂固定粘接。本发明提供的隔音贴板针对现有技术中隔音墙不能便捷施工及重复使用、隔音棉效果不佳等问题，根据低动态弹性模量的软质材料声桥传声作用弱及空气层隔音原理，发明了一种施工便捷、易切割拼装和可重复使用、结构简单且可有效增强墙壁隔音效果的室内即有墙壁用隔音贴板。
