Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an on-site installed adjustable sound absorption structure. Background Art

[0002] At present, the sound-absorbing products with aluminum alloy frames are manufactured in the processing plant according to the product specifications determined at the installation site, and then transported to the site for installation. The installation site is relatively complicated. It often happens that after the product specifications are determined and manufactured, the actual product specifications change due to the on-site wall construction, resulting in the scrapping of the manufactured products or returning them to the factory for modification, causing great losses and wasting time. To avoid such situations, the best solution is to directly manufacture or install the products on site. At present, PVC profiles are widely used in the market as the outer frame of the sound-absorbing products installed on site. Although this profile is easy to install, it has poor flame retardant properties and cannot be used in most public buildings. Utility Model Content
