Description

Technical Field

[0001] This utility model relates to the field of curtain wall installation technology, specifically to a refined steel keel structure and curtain wall system. Background Technology

[0002] In traditional curtain wall construction, refined steel mullions and beams are the core components of the curtain wall support frame, forming the curtain wall's backbone. The connection quality between the refined steel mullions and beams directly determines the overall structural stability and aesthetic refinement of the curtain wall. Currently, in traditional curtain wall construction, the connection between refined steel mullions and beams often uses a conventional square steel core connection system. However, during construction, the square steel core needs to be welded to the refined steel mullions, which presents the following problems: 1) The amount of on-site welding is large, resulting in low construction efficiency. Welding operations can easily burn the surface of the beams and mullions, requiring protective measures or surface repainting after welding, making the construction cumbersome; 2) The weld joints require secondary caulking, with a caulking width often between 10-20mm, resulting in poor indoor visual effects; 3) The square steel core has a narrow applicability and is not suitable for connecting variable cross-section mullions with in-and-out sections to the beams.

[0003] Therefore, it is necessary to improve existing technologies. Summary of the Invention

[0004] The purpose of this utility model is to provide a refined steel keel structure and curtain wall system to address the shortcomings of existing technologies, thereby improving construction efficiency.

The second connecting part, the first connecting part, and the fine steel column are connected by bolts.

[0006] According to the above scheme, the first connecting part is a first U-shaped steel plate, with both ends of the first U-shaped steel plate tightly attached to the side wall of the refined steel column; the middle part of the second U-shaped steel plate is arranged back-to-back with the middle part of the first U-shaped steel plate, and both ends of the second U-shaped steel plate extend into the interior of the refined steel beam, and are respectively connected to the front inner wall and / or rear inner wall of the refined steel beam; the first U-shaped steel plate, the second U-shaped steel plate and the refined steel column are connected and fixed by connecting bolts and nuts.

[0007] According to the above scheme, the cross-section of the refined steel column is T-shaped.

[0008] According to the above scheme, the cross-section of the refined steel column is rectangular.

[0009] This utility model also employs a curtain wall system, including a first curtain wall glass and a horizontal connecting component, as well as the refined steel keel structure described above; The first curtain wall glass consists of two pieces, arranged vertically and connected by a horizontal connecting component; The transverse connection assembly includes a transverse base, a transverse pressure plate, and a transverse buckle cover; The transverse base is arranged horizontally along the front side of the refined steel beam, and the transverse base is connected and fixed to the refined steel beam constructed of refined steel keel. The middle part of the horizontal base extends outward, and the extension of the horizontal base is connected to the horizontal pressure plate, so that an upper cavity and a lower cavity are formed between the horizontal base and the horizontal pressure plate, separated by the extension of the horizontal base; the lower edge of the first curtain wall glass located above is located in the upper cavity and is supported on the support strip, and the end of the support strip is welded and fixed to the fine steel beam; the upper edge of the first curtain wall glass located below is located in the lower cavity. The outer side of the transverse pressure plate is connected to the transverse buckle cover.

[0010] According to the above scheme, the curtain wall system also includes a second curtain wall glass and vertical connection components; The second curtain wall glass consists of two pieces, arranged one above the other, and connected by a horizontal connecting component. One of the second curtain wall glass panels is arranged side by side with one of the first curtain wall glass panels, and the two are connected by a vertical connecting component; The vertical connecting assembly includes a vertical base, a vertical pressure plate, and a vertical buckle cover; The vertical base is arranged vertically along the front side of the refined steel column of the refined steel keel structure; the vertical base is connected and fixed to the refined steel column; The middle part of the vertical base extends outward, and the extension of the vertical base is connected to the vertical pressure plate, so that a left cavity and a right cavity are formed between the vertical base and the vertical pressure plate, separated by the extension of the vertical base; the right edge of the first curtain wall glass located on the left side is located in the left cavity, and the left edge of the second curtain wall glass located on the right side is located in the right cavity. The outer side of the vertical pressure plate is connected to the vertical buckle cover.

This utility model uses prefabricated first and second connecting parts in the factory, eliminating the need for on-site welding. The fixed connection between the refined steel columns and refined steel beams can be completed simply by using bolts and nuts. When the entire refined steel structure is used in a curtain wall system, it can significantly reduce the complex on-site processing procedures. At the same time, when used in a curtain wall system, there is no need for secondary sealing treatment, which directly eliminates the tedious waiting and treatment process of sealing in traditional construction, simplifies the on-site construction process, shortens the construction cycle, and improves the overall construction efficiency.

[0016] 2.

The three are firmly connected by bolts and nuts. This multi-part force-bearing connection method can improve the overturning resistance of the beam, ensure the stable and reliable mechanical properties of the connection, and guarantee the construction quality of the curtain wall system.

[0017] 3. The connection structure between the first U-shaped steel plate and the second U-shaped steel plate in this utility model can be applied to the connection and fixing of conventional and variable cross-section columns and beams, without the need to design special connection components for different cross-section types, thus broadening the application range.
