[0002] With the acceleration of the urbanization process, modern buildings not only pursue the beauty and uniqueness of the appearance, but also pay more attention to functionality and practicality. As the outer enclosure structure of a building, the curtain wall not only undertakes the task of beautifying the building appearance, but also must have excellent functions such as waterproofing, heat preservation, and heat insulation. The installation support cavity of traditional aluminum plates is relatively large. If the rainwater accumulated in the curtain wall cannot be drained in time, the stagnant water in the wall panel for a long time will corrode the metal material, affect the life of the curtain wall, and affect the structural safety over time. Content of the Utility Model

[0003] Based on this, it is necessary to provide a waterproof curtain wall structure for the problem that if the rainwater accumulated in the curtain wall cannot be drained in time, the stagnant water in the wall panel for a long time will corrode the metal material and affect the life of the curtain wall.

[0007] A cross beam, installed in the installation notch through a connecting piece to provide an additional support point for the aluminum plate.

[0008] In one embodiment, when adjacent aluminum plates are installed, the bent portion of the lower aluminum plate is located inside the upper aluminum plate, and the height of the inner port is greater than the height of the outer port to form a potential difference.

[0009] In one embodiment, the side of the vertical beam away from the main structure has symmetrically arranged lifting plates, and a dust sealing rubber strip is installed between the symmetric lifting plates.

[0010] In one embodiment, the vertical beam internally has a left frame and a right frame, a water sealing rubber strip and an air sealing rubber strip are installed between the left frame and the right frame, and an equal pressure chamber is formed between the water sealing rubber strip and the air sealing rubber strip.

[0028] The following will describe the waterproof curtain wall structure of the present utility model in conjunction with Figures 1-4 the description of the waterproof curtain wall structure of the present utility model.

[0029] As Figure 1 shown in an embodiment, a waterproof curtain wall structure includes a vertical beam 100, an aluminum plate 200, and a cross beam 300.

[0030] Specifically, the vertical beam 100 is installed on the main structure through a connecting piece and has an installation notch 110.

[0031] The aluminum plate 200 is installed on the vertical beam 100 through a connecting piece. One side has a bent portion 210, and a notch 220 is formed between the aluminum plate 200 and the upper aluminum plate 200. A seal 230 is installed in the notch 220. Optionally, a moisture-proof film 240 is laid on the back of the aluminum plate 200. The moisture-proof film 240 is usually made of a polymer material such as polyethylene (PE), polypropylene (PP), etc., and has good waterproof and breathable properties. It can form a protective layer on the back of the aluminum plate 200 to prevent moisture penetration. At the same time, the moisture-proof film 240 also has breathability and can allow water vapor to pass through, thereby keeping the back of the aluminum plate 200 dry.

[0032] The cross beam 300 is installed in the installation notch 110 through a connecting piece to provide additional support points for the aluminum plate 200.

[0033] It should be noted that the connecting piece can be one or a combination of expansion bolts, chemical bolts, and high-strength bolts.

[0034] When installing this waterproof curtain wall structure, first fix the vertical beam 100 on the building main structure through a special connecting piece to ensure the stability of the vertical beam 100. Then, install the cross beam 300 in the installation notch 110 of the vertical beam 100, and fix the cross beam 300 and the vertical beam 100 through a connecting piece. Then, install the aluminum plate 200 with the bent portion 210 on the vertical beam 100 and the cross beam 300 through a connecting piece. A seal 230 is installed in the notch 220 formed between two adjacent aluminum plates 200 to ensure the sealing performance of the joint. Through the cooperation of the bent portion 210 of the aluminum plate 200 and the seal 230, water is effectively prevented from penetrating into the curtain wall interior through the joint. At the same time, the cross beam 300 provides additional support points, enhancing the stability of the entire curtain wall structure.

[0035] In this embodiment, when adjacent aluminum plates 200 are installed, the bent portion 210 of the lower aluminum plate 200 is located inside the upper aluminum plate 200, and the height of the inner port is greater than that of the outer port to form a certain potential difference, thus forming a water guiding structure. When rainwater flows along the surface of the aluminum plate 200, it will be blocked by the bent portion 210, forcing the water to flow into the designed drainage path instead of penetrating into the building interior. In addition, the seal strip 230 can not only prevent moisture penetration, but also absorb the tiny displacement of the aluminum plate 200 caused by temperature difference or wind pressure change, ensuring the stability of the aluminum plate 200 under wind load.

[0036] As Figure 2 and Figure 3 shown, in one embodiment, the side of the vertical beam 100 away from the main structure has symmetrically arranged lifting plates 120, and a dust sealing rubber strip 130 is installed between the symmetric lifting plates 120.

[0037] Preferably, the vertical beam 100 has a left frame 140 and a right frame 150 inside. A water sealing rubber strip 160 and an air sealing rubber strip 170 are installed between the left frame 140 and the right frame 150, and an equal pressure chamber 180 is formed between the water sealing rubber strip 160 and the air sealing rubber strip 170.

[0038] Furthermore, by installing the dust sealing rubber strip 130 between the lifting plates 120, dust can be effectively prevented from entering the interior of the curtain wall; by installing the water sealing rubber strip 160 and the air sealing rubber strip 170 inside the vertical beam 100, the waterproof and airtight performance of the curtain wall can be improved. The design of the equal pressure chamber 180 can effectively reduce the influence of wind pressure on the curtain wall, improve the waterproof performance of the curtain wall, and the equal pressure chamber 180 communicates with the installation notch 110 to ensure that the moisture in the equal pressure chamber 180 can be discharged through the installation notch 110, avoiding corrosion problems caused by water accumulation.

[0039] As Figure 4 shown, in one embodiment, in order to further improve the waterproof performance of the curtain wall structure and ensure smooth drainage inside the structure, an inclined plate 310 is fixedly installed inside the cross beam 300. The inclined plate 310 abuts against the vertical beam 100. The surface of the inclined plate 310 has a diversion groove 311, and the surface of the cross beam 300 has a through hole 320. Through the design of the inclined plate 310 and the diversion groove 311, water flow can be effectively guided to drain, preventing moisture from accumulating inside the cross beam 300, improving the waterproof performance of the curtain wall, reducing the residence time of moisture inside the cross beam 300, reducing the corrosion risk, and prolonging the service life of the curtain wall structure. In addition, the design of the inclined plate 310 helps to reduce the additional load caused by water accumulation inside the cross beam 300, thereby improving the stability of the overall structure.

[0040] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0041] The above-described embodiments only express several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the appended claims.
