Oubak Building Materials has obtained a patent for a snap-fit ​​aluminum structure for sound-absorbing ceilings, making ceiling installation and replacement more flexible.

Financial World News, July 11, 2025 – Data from the National Intellectual Property Administration reveals that Guangzhou Oubake Building Materials Technology Co., Ltd. has been granted a patent titled "A Buckle-Type Sound-Absorbing Aluminum Ceiling Structure", with the authorized announcement number CN223088742U and a filing date of September 2024.
According to the patent abstract, the utility model relates to a buckle-type sound-absorbing aluminum ceiling structure, which comprises a mounting frame fitted with four first clamping members. The bottom of the mounting frame is connected to four second clamping members, and four first slotted holes are formed in the lower part of the mounting frame. An outer connecting frame is clamped between the lower sections of the second clamping members. A connecting plate is slidably connected to the mounting frame, the lower part of the connecting plate is attached with four guide pieces, and moisture-proof sound-absorbing cotton is mounted on the connecting plate. Keel frames are arranged on the upper sides of both the left and right portions of the moisture-proof sound-absorbing cotton. 
In the utility model, the first clamping members are fastened onto the keel frames, enabling greater flexibility during ceiling installation and replacement and effectively boosting installation efficiency. Meanwhile, adjusting pieces are adopted to regulate the spacing between the mounting frame and the connecting plate, reducing gaps generated between the upper part of the mounting frame and the connecting plate during clamping for enhanced structural stability. The moisture-proof sound-absorbing cotton not only prevents friction between metal components of the connecting plate and keel frames but also suppresses abnormal noise between the keel frames and the ceiling slab.
