Description

Technical Field

[0001] This utility model relates to a corner node connection structure for glass curtain walls, belonging to the field of glass curtain wall technology. Background Technology

[0002] In the field of modern architecture, glass curtain walls have become the mainstream building envelope due to their transparency and aesthetic appeal. For the structural design of glass curtain wall corners, the current common practice is to use beams and columns as the traditional supporting framework. This traditional structure has several drawbacks. Firstly, because the beams and columns occupy space, they significantly reduce the visible range at the corners of the glass curtain wall, limiting interior lighting and external views, failing to fully utilize the transparency and openness of the glass curtain wall, and reducing the building's visual appeal and space utilization value. Secondly, the glass and exterior components are directly fixed to the framework using bolts, adhesives, or other relatively fixed methods, making disassembly extremely complex during later maintenance, replacement, or upgrades. This not only requires significant manpower and resources but also easily damages the glass and exterior components, increasing maintenance costs and extending maintenance cycles, making it difficult to meet the needs for convenient maintenance and efficient replacement during long-term building use. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a corner node connection structure for glass curtain walls.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a corner node connection structure for a glass curtain wall, comprising a corner steel column, a transition channel steel, a connecting component, a glass sub-frame, and corner glass; the transition channel steel is connected and fixed to the rear end of the corner steel column, used to connect the corner steel column to the main building structure; the connecting component comprises a connecting steel pipe and connecting aluminum materials fixed on both sides of the connecting steel pipe, the rear end of the connecting steel pipe is fixed to the corner steel column, the inner ends of the glass sub-frame are respectively inserted into the connecting aluminum materials located on both sides of the connecting steel pipe, the inner middle part of the glass sub-frame is connected and fixed to the front end of the connecting steel pipe, and the corner glass is fixed to the outer side of the glass sub-frame by structural adhesive.

The glass subframe and the connecting aluminum materials are engaged through the insertion protrusions and slots.

[0006] The inner center of the glass subframe has two protruding strips, and the front side of the connecting steel pipe has a connecting part. The two protruding strips of the glass subframe are respectively fixed on both sides of the connecting part.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] As attached Figure 1-2 As shown, the corner node connection structure of the glass curtain wall described in this utility model includes a corner steel column 1, a transition channel steel 2, a connecting component, a glass subframe 3, and a corner glass 4.

[0022] The transition channel steel 2 is connected and fixed to the rear end of the corner steel column 1, and is used to connect the corner steel column 1 to the main building structure 5. In this embodiment, the transition channel steel 2 and the prefabricated embedded parts on the main building structure 5 can be fixed by welding. Horizontal waist holes can be opened on the transition channel steel 2 to adjust the front and rear of the corner steel column 1 to reduce errors in the construction process.

[0023] The connecting assembly includes a connecting steel pipe 6 and connecting aluminum materials 7 fixed on both sides of the connecting steel pipe 6. The rear end of the connecting steel pipe 6 is fixed to the corner steel column 1. In this embodiment, the connecting aluminum materials 7 are fixed to the connecting steel pipe 6 by multiple self-tapping screws, and the connecting steel pipe 6 is fixed to the corner steel column 1 by welding.

[0024] By combining the connecting steel pipe 6 and the connecting aluminum material 7, a rigid-flexible connection structure is formed, which utilizes the high strength of steel and the aesthetics and corrosion resistance of aluminum profiles, thereby improving the load-bearing capacity and stability of the connection components.

[0025] The inner ends of the glass subframe 3 are respectively inserted into the connecting aluminum materials 7 located on both sides of the connecting steel pipe 6, and the middle of the inner side of the glass subframe 3 is fixed to the front end of the connecting steel pipe 6. Specifically, both inner ends of the glass subframe 3 have insertion protrusions 31, and the connecting aluminum materials 7 located on both sides of the connecting steel pipe 6 are provided with slots 71 that match the insertion protrusions 31. The glass subframe 3 and the connecting aluminum materials 7 are engaged through the insertion protrusions 31 and slots 71 to achieve precise initial positioning. The engagement structure facilitates installation and disassembly, which not only improves construction efficiency, but also makes it more convenient for later maintenance and replacement of parts, reducing maintenance costs. The middle of the inner side of the glass subframe 3 has two protrusions 32, and the front side of the connecting steel pipe 6 has a U-shaped connecting part 61. The two protrusions 32 of the glass subframe 3 are fixed to both sides of the connecting part 61 by screws to achieve final positioning and fixation, ensuring installation accuracy and stability.

[0026] The corner glass 4 is fixed to the outside of the glass subframe 3 with structural adhesive, and the positioning and installation of the corner glass 4 have been completed. In this embodiment, a rubber pad 10 is provided between the glass subframe 3 and the corner glass 4 to effectively buffer the displacement and deformation of the glass panel caused by wind load, temperature change and other factors, reduce the friction and collision between the glass and the subframe, and thus avoid the glass from cracking due to stress concentration.

[0027] Compared with existing technologies, this application eliminates the traditional structure of crossbeams and columns as supporting keel, and adopts a combination of rigid and flexible connecting components, which not only ensures structural stability, but also avoids the impact of redundant components on the visible surface and improves the transparency of corner glass 4.

[0028] Furthermore, aluminum back plates 72 are provided on the connecting aluminum parts on both sides of the connecting steel pipe 6. The aluminum back plates 72 are parallel to the corner glass 4 on the same side, which plays a supporting and protective role, enhances the stability of the overall structure, and also ensures the appearance of the interior side.

[0029] Furthermore, an aluminum alloy pressure plate 8 is fixedly installed on the outside of the glass subframe 3. The aluminum alloy pressure plate 8 presses the corner glass 4 located on both sides of the glass subframe 3 from the outside to ensure the stability of the corner glass 4. Sealant 9 is applied to the contact position between the aluminum alloy pressure plate 8 and the corner glass 4 to improve the sealing performance.

[0030] Furthermore, an aluminum alloy cover 81 is provided on the outer side of the aluminum alloy pressure plate 8. The aluminum alloy cover 81 is snapped onto the aluminum alloy pressure plate 8.
