Description

A retractable aluminum curtain wall

technical field

The utility model relates to the field of building peripheral protection structures, in particular to a retractable aluminum plate curtain wall.

Background technique

Modern buildings often use metal aluminum plates as exterior wall decoration materials for their beauty, but during their use, due to sunlight, metal plates often deform after absorbing heat. The reason is mainly because the four sides of the metal plate are fixed.

As we all know, all physical materials have thermal expansion and contraction, and the same is true for metal panels used as exterior wall decoration. Moreover, the heat absorption is also different according to the depth of the color. The heat absorption of the sprayed metal plate with a dark color is more obvious, and the thickness of the decorative metal plate is often not particularly thick. Therefore, when the four sides are fixed, the deformation generated after the metal plate is heated cannot be released, resulting in deformation of the metal plate surface, causing the original very smooth decorative surface to become uneven and very ugly.

The modern commonly used metal plate installation method is to use the aluminum alloy corner piece to connect the metal plate with a screw, and then install it in the form of connecting the keel with self-tapping nails or self-tapping self-drilling nails. There are two defects in this installation method: first, as mentioned above, the four sides of the aluminum plate are fixed and the flatness of the aluminum plate changes due to the limitation of expansion and contraction, which affects the overall flatness of the curtain wall; second, when steel structural materials are used as the When the main force keel is used, nylon gaskets are used to separate the aluminum alloy corner piece from the steel structure material. However, since the nylon gasket is a loose part, it is easy to drop during the actual installation process, and workers are often unwilling to install it during the actual operation process, thus bringing hidden dangers to the project.
