Sound insulation and noise reduction mechanism for building outer wall transformation

Abstract

The invention relates to the technical field of building outer walls, in particular to a sound insulation and noise reduction mechanism for building outer wall transformation. The sound insulation and noise reduction mechanism comprises a building outer wall main body, wherein multiple groups of sound absorption holes are arranged on the surface of the building outer wall main body; the rear end of each sound absorption hole is fixedly connected with a first noise reduction groove; a first noise reduction diaphragm is respectively glued to the inner wall of each first noise reduction groove; the rear end of each first noise reduction groove is fixedly connected to a conveying channel; the rear end of each conveying channel is fixedly connected to the front end of each second noise reduction groove; a second noise reduction diaphragm is respectively glued to the inner wall of each second noise reduction groove; and the rear end of each second noise reduction diaphragm is arranged at the front end of the noise reduction layer. In a using process, the interior of the building outer wall main body is moistened and dried, the practicability and the service life of the device in the using process are further ensured, meanwhile, the building outer wall main body and a moist eliminating body device can be relatively stably and safely protected, and the device is more reasonable and safer.

Description

technical field [0001] The invention relates to the technical field of building exterior walls, in particular to a sound insulation and noise reduction mechanism for building exterior walls. Background technique [0002] A kind of enclosing building, makes it to form indoor, outdoor boundary member and is collectively referred to as exterior wall, and its function has: bear certain load, keep out wind and rain, heat insulation, prevent noise, fire safety etc., such as publication number is CN109898693A disclosure A method for thermal insulation, energy saving and water drainage of building exterior walls, which is constructed in strict accordance with the design standards for thermal insulation and energy saving of building exterior walls, which can ensure construction quality, performance of thermal insulation, energy saving and water discharge, and ensure smooth acceptance in the later stage. It is especially suitable for the post-insulation and energy-saving transformatio...
