Description

Technical Field

[0001] This invention relates to the technical field of curtain wall installation, and in particular to a large-angle combined curtain wall system spanning expansion joints. Background Technology

[0002] With the development of building curtain walls in my country, curtain wall forms and shapes are becoming increasingly diverse. In order to enrich the expressive forms of curtain walls, combinations of glass, aluminum panels, and other materials are often used to express artistic design intentions. In curtain wall projects, to demonstrate the flatness and transparency of the curtain wall, glass is often used as the transparent material, and aluminum panels are used as the irregularly shaped surface material.

[0003] However, due to factors such as earthquakes, the expansion joints of the building structure can deform, easily leading to damage to the curtain wall. Therefore, expansion joint structures are installed in the curtain wall. Existing Chinese utility model patent application number CN201820287080.7 discloses a corner expansion joint connection device for a glass curtain wall, connecting two glass curtain walls forming a corner. It includes a first expansion sealing component and a second expansion sealing component. The first expansion sealing component includes an expansion plate, a first waterproof strip, and two fixing seats. The two fixing seats are respectively fixedly connected to the columns of the two glass curtain walls. The expansion plate includes a horizontal expansion part and a vertical expansion part connected as one unit. The free ends of the horizontal and vertical expansion parts are respectively inserted into the two fixing seats. The horizontal expansion part can slide horizontally relative to the fixing seats, and the vertical expansion part can slide vertically relative to the fixing seats. The first waterproof strip is disposed within the fixing seats. The second expansion sealing component includes a second waterproof strip and two strip fasteners. The two ends of the second waterproof strip are respectively fixedly connected to the columns of the two sides through the strip fasteners.

[0004] The above solution has the following disadvantages: 1. During installation, the waterproof strip is in a stretched and deformed state, which has poor adaptability to deformation and is easily damaged; 2. Both ends of the expansion joint are slidably connected to the waterproof strip, resulting in poor stability and resettlement, making it unsuitable for installation on large-angle curtain wall structures; 3. Only expansion joints are installed between glass curtain walls, resulting in a single shape that cannot adapt to the installation of curtain walls with different tilt angles. Summary of the Invention

[0005] This invention provides a large-angle combined curtain wall system that spans expansion joints, which simplifies the skeleton structure of aluminum panel curtain walls, eliminates the need for horizontal keels between vertical keels and steel rectangular tubes, and allows the position of the steel rectangular tubes to be changed to adapt to curtain wall installations with different inclination angles and spans.

[0006] The technical problems to be solved are: 1. During installation, the waterproof strip is in a stretched and deformed state, which has poor adaptability to deformation and is easily damaged; 2. Both ends of the expansion joint are slidably connected to the waterproof strip, resulting in poor stability and resettlement, making it unsuitable for installation on large-angle curtain wall structures; 3. Only expansion joints are installed between glass curtain walls, resulting in a single shape that cannot adapt to the installation of curtain walls with different tilt angles.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a large-angle composite curtain wall system spanning an expansion joint, comprising a building structure, an expansion joint disposed between the building structures, glass curtain walls installed on both sides of the internal corner of the building structure, and aluminum panel curtain walls installed between the glass curtain walls.

The insulated glass is fastened to the vertical keels by aluminum alloy pressure blocks. The aluminum panel curtain wall includes a first curtain wall set on one side of the internal corner of the building structure and a second curtain wall set on the other side of the internal corner of the building structure, wherein the first curtain wall and the second curtain wall are slidably fitted at the expansion joint; The first curtain wall includes a first mounting steel plate installed on the vertical keel, a first steel rectangular tube installed on the building structure near the expansion joint, a first angle steel connecting the first mounting steel plate and the first steel rectangular tube, a first aluminum plate installed on the first angle steel, and a connecting angle steel connecting the first angle steel and the building structure. The second curtain wall includes a second mounting steel plate installed on the vertical keel, a second steel rectangular tube installed on the building structure near the expansion joint, a second angle steel connecting the second mounting steel plate and the second steel rectangular tube, and a second aluminum plate installed on the second angle steel. The end of the second aluminum plate near the expansion joint is bent toward the inside of the first aluminum plate and slides with the first aluminum plate. A sealing strip is installed between the second aluminum plate and the first aluminum plate. A bellows plate is installed between the first and second steel rectangular tubes.

[0008] The present invention provides a large-angle composite curtain wall system spanning deformation joints, wherein the first mounting steel plate and the second mounting steel plate are in an L-shaped structure.

[0009] The present invention discloses a large-angle combined curtain wall system spanning deformation joints. Furthermore, both the first aluminum plate and the second aluminum plate are connected to the vertical keel through edge sealing members, and the edge sealing members are pressed onto the vertical keel by aluminum alloy pressure blocks.

[0010] The present invention discloses a large-angle combined curtain wall system spanning deformation joints. Further, the edge sealing component includes a Z-shaped component with one end anchored to a first aluminum plate or a second aluminum plate, and a bent section formed on the other end of the Z-shaped component for attaching to the vertical keel. The aluminum alloy pressure block presses on the Z-shaped component, and an EPDM rubber strip is provided between the aluminum alloy pressure block and the Z-shaped component.

[0011] The present invention discloses a large-angle combined curtain wall system spanning deformation joints. Further, a first inner angle steel is connected between the vertical keel and the connecting angle steel, and a first inner aluminum plate is installed on the inner side of the first curtain wall between the vertical keel and the building structure. The first inner aluminum plate is connected to the first inner angle steel.

[0012] The present invention provides a large-angle composite curtain wall system spanning expansion joints. Further, a second inner angle steel is installed on the inner side of the second curtain wall between the vertical keel and the second steel rectangular tube, and a second inner aluminum plate is installed on the second inner angle steel between the vertical keel and the building structure.

[0013] The present invention provides a large-angle composite curtain wall system spanning deformation joints. Furthermore, an angle bracket is installed on the second steel rectangular tube, and the second inner angle steel is fixed to the angle bracket.

[0014] The present invention discloses a large-angle combined curtain wall system spanning an expansion joint. Further, a fastener is installed at one end of the first aluminum plate near the second aluminum plate, and an installation groove is formed on the fastener. The sealing strip is connected to the installation groove.

[0015] The present invention discloses a large-angle combined curtain wall system spanning deformation joints. Further, connecting angle brackets are installed between the end of the first aluminum plate near the first steel rectangular tube and the first angle steel, and between the end of the second aluminum plate near the second steel rectangular tube and the second angle steel.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This application adds a first steel rectangular tube and a second steel rectangular tube at the expansion joint, and installs the bellows plate between the first steel rectangular tube and the second steel rectangular tube, so that the bellows plate is in a natural state, thereby increasing its upper limit of adapting to external deformation and preventing it from being damaged; 2. By fixing the first aluminum plate and the second aluminum plate to the angle steel, and only slidingly engaging the ends of the first aluminum plate and the second aluminum plate, not only can it adapt to structural deformation, but the structural stability of the curtain wall itself is also better. 3. This application simplifies the frame structure of aluminum panel curtain walls by installing steel plates on the vertical keels and using angle steel as the installation frame for aluminum panels. It eliminates the need for horizontal keels between the vertical keels and the steel rectangular tubes, allowing the position of the steel rectangular tubes to be changed to adapt to curtain wall installations with different tilt angles and spans. 4. By sliding the ends of the first and second aluminum plates together and using the steel rectangular tubes added at the expansion joints, it can adapt to the installation of curtain wall structures with large spans and large corners. 5. By installing steel plates on the vertical keels and using angle steel as the installation frame for the aluminum panels, the frame structure of the aluminum panel curtain wall is simplified, making installation more convenient; 6. The installation position of the steel plate on the vertical keel can be adjusted at will according to the size of the outer aluminum plate, which can be used for the installation of aluminum plates of various sizes to meet different design appearance requirements. In addition, the angle steel can be appropriately adjusted on the installation steel plate to ensure the installation accuracy of the aluminum plate. The horizontal keel between the vertical keel and the steel rectangular tube is eliminated, which simplifies the skeleton structure of the aluminum panel curtain wall, saves construction costs, and improves construction efficiency. 7. The mounting steel plate serves as both a mounting base for the aluminum plate and a limiting structure for the edge banding, restricting the position of the edge banding and preventing deformation of the aluminum plate ends that could cause leakage. 8. By installing steel plates, the skeleton structure of the aluminum panel curtain wall is simplified, the load on the load-bearing components is reduced, thereby reducing the cross-sectional size of the steel rectangular tube, reducing installation difficulty and construction costs.
