The function of composite aluminum curtain wall, preparation and maintenance before installation
The rapid economic development has brought development opportunities to my country's construction industry. The decoration of the outer wall has been paid more and more attention by people. As a new type of exterior wall decoration material, composite aluminum curtain wall has reached an updated level in terms of beauty, color, chromatic aberration, durability, flatness, and shape, providing a broad imagination space for architects to design and create. At the same time, the composite aluminum curtain wall has the characteristics of convenient processing and production and fast construction speed, which is more and more favored by the construction industry and people.
The function of the composite aluminum panel curtain wall mostly belongs to the exterior decoration and outer protection type of the building, that is, the building itself has ordinary brick walls or other types of walls. The composite aluminum curtain wall installed on the outside not only plays a role in the decoration of the building itself, but also plays a role in protecting the building. Such aluminum curtain wall itself requires better wind pressure resistance, water tightness, air tightness and weatherproof sealing system. Before the production and installation of composite aluminum curtain wall, the building design and construction drawings should be checked, and the building should be retested, and the original design can be adjusted according to the actual test results before processing and assembly. The equipment and machines used in the processing of curtain wall components should meet the requirements of the processing accuracy of curtain wall components, and their measuring tools should be regularly measured and verified.
In addition to the decoration effect of the composite aluminum curtain wall, its wind resistance capability should also be considered. Curtain wall panels are mainly subjected to wind load, and their resistance to wind load deformation depends on the thickness of the panel, the aspect ratio, the distance between fulcrums and the supporting conditions. If the division of the facade of the aluminum panel curtain wall is too large, the thickness of the panel is much smaller than the dimensions in the two directions of length and width, which will make the panel surface easy to deform and deform under the action of wind load, which will affect the overall effect of the curtain wall. If the design is improper, it will leave irreversible plastic deformation on the board surface. In panel type control applications, various factors are generally considered comprehensively, and then the support and fixing method of the panel assembly and the position and quantity of the reinforcement ribs behind the panel are determined based on actual sample testing and experience.
Alloy aluminum plate is to add various alloying elements in the aluminum plate processing process to improve the mechanical properties and chemical indicators of the aluminum plate. So how to maintain the alloy aluminum plate?
1. When the alloy aluminum plate is stored, it is forbidden to store the chemical data and wettability data together.
2. During transportation, the alloy aluminum plate should be covered with thatch cloth to prevent the intrusion of rain and snow.
3. The storage environment of the alloy aluminum plate should be dry, bright, ventilated, and non-corrosive.
4. It is necessary to handle the aluminum plate with care during the handling process, and be careful not to bump the surface to cause damage to the appearance, which will affect the appearance.
5. When the alloy aluminum plate is stored, it is recommended to put the small standard aluminum plate on the shelf. The storage method of the large standard aluminum thick plate is to separate the bottom from the ground with a skid, and the distance from the ground is greater than 10CM.
