Description

Technical Field

[0001] The utility model belongs to the technical field of building curtain walls, and in particular relates to a perforated aluminum plate curtain wall connection system. Background Art

[0002] Curtain wall is the outer wall of a building. It does not bear weight and is hung like a curtain, so it is also called a suspended wall. It is a lightweight wall with decorative effects commonly used in modern large and high-rise buildings. It is mainly composed of a structural frame and inlaid panels. It is a building enclosure structure that does not bear the load and function of the main structure.

[0003] Curtain walls are a building's outer envelope, integrating architectural technology, functionality, and artistry. As a premium exterior wall, open aluminum curtain walls are highly favored by architects and developers for their clean, uncluttered appearance and multi-dimensional, multi-layered effects.

[0004] However, the existing open aluminum curtain wall still has the following shortcomings (such as Figure 1 First, it was difficult to precisely locate the beams and columns on site. The aluminum panels were attached to the beams and columns with nails, which made it difficult to eliminate deformation caused by thermal expansion and contraction. Both factors resulted in uneven aluminum panel surfaces. Second, to allow sufficient space for the self-tapping screws, the gaps between the aluminum panels needed to be at least 12mm wide. This gap fragmented the entire facade, significantly reducing the aesthetics of the finished curtain wall. Utility Model Content

[0005] The purpose of the utility model is to provide a perforated aluminum plate curtain wall connection system, which is mainly used to improve the flatness of the aluminum plate surface and enhance the connection strength between the connecting piece and the aluminum plate surface.

[0006] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0007] A perforated aluminum panel curtain wall connection system includes multiple aluminum panels, aluminum alloy sub-frames fixed to the aluminum panels, and steel keels for fixing the aluminum alloy sub-frames via screws; the aluminum alloy sub-frames include a first aluminum alloy sub-frame and a second aluminum alloy sub-frame, the first aluminum alloy sub-frame and the second aluminum alloy sub-frame are respectively fixedly connected to two adjacent aluminum panels via rivets, and the first aluminum alloy sub-frame and the second aluminum alloy sub-frame are arranged in a mutually clamped structural form.

[0008] Furthermore, in the present invention, a snap-in groove is provided on the first aluminum alloy sub-frame, and a snap-in hook is provided on the second aluminum alloy sub-frame; wherein the snap-in hook is inserted into the snap-in groove to realize the snap connection and fixed limitation of the first aluminum alloy sub-frame and the second aluminum alloy sub-frame.

[0009] Furthermore, in the present invention, a flexible gasket is provided at the connection point between the connecting groove and the connecting hook.

[0010] Furthermore, in the present invention, a sealing gasket is provided at the junction of the aluminum alloy sub-frame and the steel keel.

[0011] Furthermore, in the present invention, the screws are stainless steel self-drilling screws.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0023] Example

[0024] like Figures 2-4 As shown, the present invention discloses a perforated aluminum curtain wall connection system. Through ingenious design, it improves the flatness of the aluminum curtain wall and enhances the connection strength between the connector and the aluminum panel surface. Its specific structure includes an aluminum panel 1 and an aluminum alloy sub-frame 2 fixed to the aluminum panel 1. Multiple aluminum panels 1 are connected and combined to form the aluminum curtain wall. The aluminum alloy sub-frame 2 serves as the connector of the aluminum curtain wall, connecting the aluminum curtain wall to the steel keel. The aluminum alloy sub-frame 2 is fixed to the steel keel 8 by screws 3. The junction between the aluminum alloy sub-frame 2 and the steel keel 8 is provided with a sealing gasket 11. To facilitate the connection and installation of the screws 3, the screws 3 are stainless steel self-drilling screws.

[0025] To reduce the gap between adjacent aluminum panels when the aluminum alloy sub-frame serves as a connector and improve the smoothness of the aluminum curtain wall, the aluminum alloy sub-frame 2 is designed as a two-part structure: a first aluminum alloy sub-frame 5 and a second aluminum alloy sub-frame 6. The first and second aluminum alloy sub-frames 5 and 6 are each fixedly connected to the adjacent aluminum panels via rivets 4. The first and second aluminum alloy sub-frames 5 and 6 are configured to engage with each other, ensuring that the adjacent aluminum panels maintain a matching positional relationship after connection and ensuring the smoothness of the aluminum curtain wall. The specific engaging method is as follows: a engaging groove 9 is provided on the first aluminum alloy sub-frame 5; a engaging hook 10 is provided on the second aluminum alloy sub-frame 6; the engaging hook 10 is inserted into the engaging groove 9 to achieve a positional engagement between the first and second aluminum alloy sub-frames 5 and 6. When the aluminum alloy sub-frame 2 is installed as a connecting part, the first aluminum alloy sub-frame 5 and the second aluminum alloy sub-frame 6 are first fixedly connected to the aluminum veneer 1 respectively, and then the second aluminum alloy sub-frame 6 is fixed to the steel keel 8 by the countersunk screws 3. The first aluminum alloy sub-frame 5 is clamped on the second aluminum alloy sub-frame 6, and a flexible gasket 7 is provided at the clamping point between the two to increase the friction force to complete the installation of the aluminum alloy sub-frame. Since the final installation is completed by clamping during the installation process, there is no need to reserve a special installation gap for the installation of the aluminum alloy sub-frame, which can greatly reduce the gap between the two adjacent aluminum veneers, thereby hiding the aluminum alloy sub-frame and improving the overall aesthetics and flatness of the aluminum plate curtain wall.

[0026] Through the above design, the curtain wall connection system of the present invention does not need to reserve a special installation gap for the installation of the aluminum alloy sub-frame, which can greatly reduce the gap between two adjacent aluminum panels, thereby hiding the aluminum box in the sub-frame and improving the overall aesthetics and flatness of the aluminum panel curtain wall.

[0027] The above embodiment is only one of the preferred implementation methods of the present invention and should not be used to limit the scope of protection of the present invention. Any changes or modifications that have no substantive meaning made to the main design concept and spirit of the present invention, as long as the technical problems they solve are still consistent with the present invention, should be included in the scope of protection of the present invention.
