Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically to a prefabricated building wall with a sound-absorbing structure. Background Technology

[0002] Prefabricated buildings refer to the transfer of a large amount of on-site work in traditional construction methods to factories. Building components and accessories are processed and manufactured in factories, transported to the construction site, and assembled on-site using reliable connection methods. By setting up prefabricated buildings, the cumbersome procedures during on-site construction can be reduced, thereby shortening the construction cycle. Walls mainly include load-bearing walls and non-load-bearing walls, which mainly serve the functions of enclosure and space division. In load-bearing structure buildings, the walls combine load-bearing and enclosure functions. In frame structure systems, the function of the walls is to enclose and divide space.

[0003] The existing technical solutions have the following drawbacks: they are difficult to reduce noise on the outside of the prefabricated building walls, which allows noise to easily penetrate the prefabricated building walls and thus affect the user experience.

[0004] Therefore, we propose a prefabricated building wall with a sound-absorbing structure. Utility Model Content
