[0002] As a kind of architectural decoration, aluminum curtain wall can improve the aesthetics of the building.

[0003] Since the aluminum curtain wall material will expand and contract at different temperatures, in order to avoid mutual squeezing or gaps between the aluminum curtain walls, which would lead to a decrease in aesthetics, expansion joints are left during the installation process to provide the aluminum curtain walls with a certain displacement space when they expand and contract. The expansion joints are generally covered by cover panels to avoid affecting the aesthetics.

[0004] In the prior art, when the aluminum curtain wall undergoes relative displacement, the cover plate will also move under the influence of the displacement of the aluminum curtain wall. After the movement, the cover plate may be offset or deflected, resulting in the cover plate failing to provide a good shielding and aesthetic effect. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-2In an embodiment of the utility model, a curtain wall back aluminum plate with an expansion joint comprises two aluminum curtain walls 1 connected to a wall through a keel, the back of the front end plates of the two aluminum curtain walls 1 are integrally formed with a connecting plate 2 in an "L"-shaped structure, the front part of the front end plate of the aluminum curtain wall 1 is formed with a transition surface 4, and a receiving groove 3 is formed between the connecting plate 2 and the back of the front end plate of the aluminum curtain wall 1, and the ends of the two receiving grooves 3 close to each other are both open structures; the inner walls of the two receiving grooves 3 are plugged with cover plates 5, and the side end plates of the two aluminum curtain walls 1 close to each other are installed with a sealed expansion mechanism; the sealed expansion mechanism is used to limit the cover plate 5 to the installation area, and the sealed expansion mechanism is compressed or extended as the distance between the two aluminum curtain walls 1 changes.

[0020] In this embodiment: when installing the device, two aluminum curtain walls 1 are installed on the wall through aluminum keels, and then the sealing telescopic mechanism is installed and fixed to the side panels of the two aluminum curtain walls 1 respectively. After the fixing is completed, the cover plate 5 is inserted into the accommodating groove 3. After the cover plate 5 is inserted, the cover plate 5 blocks the expansion joint between the two aluminum curtain walls 1. The transition surface 4 can avoid an excessively large drop surface between the cover plate 5 and the front end plate of the aluminum curtain wall 1, thereby improving the aesthetic effect.

[0021] Please refer to Figure 1 and Figure 2 The sealing telescopic mechanism includes a mounting plate 6 fixedly connected to the two side panels of the aluminum curtain wall 1, the end of the mounting plate 6 away from the aluminum curtain wall 1 is connected to a corrugated rubber plate 7, the end of the corrugated rubber plate 7 away from the mounting plate 6 is connected to a fixing plate 8, and a dustproof rubber 11 is fixedly connected between the two fixing plates 8.

[0022] In this embodiment: after the aluminum curtain wall 1 and the keel are installed, the mounting plate 6 is fixed to the side plate of the aluminum curtain wall 1 by bolts, and the fixing plate 8 is fixedly connected to the wall by using an expansion bolt assembly, and the fixed connection position must not be a load-bearing wall. After the entire device is installed, when the aluminum curtain wall 1 undergoes thermal expansion and contraction due to temperature, the two corrugated rubber plates 7 are extended or compressed accordingly. During the deformation of the corrugated rubber plates 7, the fixing plate 8 remains stationary, so the cover plate 5 remains stationary. When the two aluminum curtain walls 1 move relative to each other, the cover plate 5 always remains in the current position, and the cover plate 5 will not deflect or tilt after moving.

[0023] Please refer to Figure 1 and Figure 2 The front end of the horizontal plate portion of the fixed plate 8 is integrally formed with a slide rail 9 protruding outward, and the inner sides of the two slide rails 9 close to each other are formed with a clamping portion protruding inward. The back of the cover plate 5 is integrally formed with a slide plate 10 protruding outward, and both sides of the slide plate 10 are provided with clamping grooves that match the outer wall of the clamping portion.

[0024] In this embodiment: during the process of inserting the cover plate 5 into the receiving groove 3, the slide plate 10 is aligned with the slide rail 9, and the snap-in groove and the snap-in portion are aligned. Then, during the process of the cover plate 5 sliding down, the slide plate 10 is inside the slide rail 9. Therefore, the cover plate 5 can be restricted by the fixed plate 8 through the slide plate 10 and the slide rail 9, so that the cover plate 5 will always remain in the installed position.

[0025] Please refer to Figure 1 and Figure 2 The mounting plate 6 is fixedly connected to the aluminum curtain wall 1 by a bolt assembly.

[0026] In this embodiment, through holes are drilled on the mounting plate 6 and the side plate of the aluminum curtain wall 1 , and then the mounting plate 6 is fixed to the aluminum curtain wall 1 using bolts and nuts.
