Description

Technical Field

[0001] This utility model belongs to the field of curtain wall and decoration engineering technology, specifically, it relates to a seamless aluminum plate construction system. Background Technology

[0002] With economic development and technological advancements, more and more high-rise buildings are being constructed, and these buildings are generally equipped with curtain walls. In curtain wall and decoration projects, aluminum panel curtain walls are widely used due to their unique texture, lightweight material, and high wear resistance.

[0003] Currently, when installing curtain walls, positioning structures need to be installed at designated locations on the wall frame. Several aluminum curtain wall panels are then installed onto these positioning structures, and the panels are spliced ​​together to form the entire curtain wall. On the one hand, this method requires pre-determining the installation locations and installing the corresponding positioning structures, making the overall installation process complex and increasing construction costs. On the other hand, this method results in gaps between adjacent aluminum curtain wall panels, leading to poor sealing after installation. This usually requires workers to apply sealant to the gaps, further increasing construction costs and severely impacting the overall aesthetics of the curtain wall.

[0004] More and more architects are inclined to adopt facade effects without sealant, so there is an urgent need to provide a seamless aluminum panel construction system that is easy to construct, economical, and aesthetically pleasing to overcome the above problems.

[0005] In view of the above, this application is hereby submitted. Summary of the Invention

[0070] When the first engaging component 3 is connected to the first bent portion 21, the protrusion 36 is at least partially attached to the end of the first bent portion 21 away from the aluminum plate body 20.

[0071] In this utility model, by providing the protrusion 36, it can serve a positioning function when the first engaging component 3 is installed onto the first bent portion 21; and when connected by countersunk self-tapping screws 5, it can make the first engaging component 3 more tightly engaged on the first bent portion 21.

[0072] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 5 Appendix Figure 6 and attached Figure 9 In one specific embodiment of this example, the first engaging component 3 is connected to the first bent portion 21 by a countersunk self-tapping screw 5.

When the inclined plate 35 is pressed, the second engaging part 4 is partially inserted into the first engaging part 3 through the gap between the inclined plate 35 and the blocking part. The engaging part 41 of the fourth vertical plate 45 is engaged into the engaging position 37 under the push of the inclined plate 35.

[0083] In this invention, by setting the locking structure (first locking component 3 and second locking component 4), the connection of adjacent aluminum plates 2 is realized, which improves the convenience of construction.
