Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, specifically to a building soundproof curtain wall structure. Background Technology

[0002] As is well known, building soundproof curtain walls are a non-load-bearing wall system that combines external envelope and noise reduction functions. They achieve sound wave blocking through special structural design and material combination, while meeting the needs of modern buildings for lightweight, aesthetics and energy saving.

[0003] A utility model patent with patent authorization announcement number CN202850287U discloses a building curtain wall, which includes, from the inside out: a base wall, several vertical keels fixed to the structural beams of the base wall, and an outer hanging plate fixed to the several vertical keels. The building curtain wall also includes several aerated concrete blocks, which are embedded between the several vertical keels, and the base wall is formed by the aerated concrete blocks.

[0004] However, existing building curtain wall structures also have certain shortcomings. Most existing building curtain wall structures simply rely on the properties of the curtain wall material itself to reduce and insulate against external noise. Due to the limitations of the curtain wall material itself, the sound insulation and noise reduction effects of building curtain walls are poor. Utility Model Content
