Description

Technical Field

[0001] This utility model relates to the field of aluminum plate technology, and in particular to an aluminum single panel for curtain wall installation. Background Technology

[0002] Aluminum single-panel panels mainly consist of a panel, reinforcing ribs, and corner brackets. The panel is the main part of the aluminum single-panel panel and is usually made of high-quality aluminum alloy sheet; the reinforcing ribs are used to enhance the strength and rigidity of the aluminum single-panel panel. Its dimensions, generally, can be customized in length by the customer. In the field of building curtain walls, aluminum single-panel panels are widely used due to their lightweight and strong weather resistance. However, existing aluminum single-panel panels have significant drawbacks in terms of indoor noise control:

[0003] Weak sound absorption: Conventional aluminum panels use a non-porous, smooth surface design with a sound wave reflectivity of >85%, which cannot effectively isolate noise from the outside of the building;

[0004] Resonance noise amplification: When the aluminum plate is subjected to external vibration (such as wind load or equipment operation), the plate is prone to resonance, producing a low-frequency booming sound of 16dB-25dB, which aggravates indoor noise pollution.

[0005] Noise transmission in the connection structure: The metal contact between the corner bracket and the keel is hard, and after installation, friction noise (peak value up to 45dB) is easily generated due to thermal expansion and contraction or structural deformation. Utility Model Content

[0006] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0007] Therefore, one objective of this utility model is to propose an aluminum single panel for curtain wall installation, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0009] Two reinforcing ribs are fixedly connected to the back of the plate, and corner brackets are fixedly connected to four points of the outer frame.

[0014] The above technical solution is adopted: This aluminum single panel has the following structural composition:
