[0027] By adopting the above technical solution, the setting of the inclined reinforcement plate can effectively enhance the structural stability between the corner keel and the connecting frame. In particular, when the connecting frame is subjected to stress, the reinforcement effect of the triangular structure can significantly disperse and alleviate stress concentration, thereby improving the bearing capacity of the entire glass curtain wall corner node and extending its service life.

By rotating the threaded rod, the support force of the anti-compression block on the inner side of the corner keel can be accurately adjusted to adapt to different rotational force and extrusion force, ensuring that the keel can maintain good anti-deformation performance under various working conditions. The connection between the load-bearing block and the internal tail end of the corner keel can evenly disperse the anti-deformation force transmitted by the threaded rod to the keel, further enhancing the stability and load-bearing capacity of the entire anti-deformation mechanism.

[0031] 1. By providing several locking reinforcement ribs between the fixing frame and the locking frame, and disposing them on both sides of the locking bolt, the connection strength between the fixing frame and the locking frame is significantly improved, effectively solving the problem of insufficient connection strength in the existing technology and enhancing the overall stability of the glass curtain wall corner node;

[0032] 2. The anti-twist mechanism effectively limits the torsion of the corner keel and fixed frame. The load-bearing plate is angle-adjustable via an adjustment shaft and adjustment slot to accommodate different installation requirements. The combination of the universal ball and the support plate ensures uniform force distribution on the inner surface of the glass curtain wall, preventing structural deformation or damage due to torsion and further enhancing the stability and safety of the overall structure. Furthermore, the combination of the positioning plate and the slot locks the load-bearing plate at its angle, ensuring the reliability of the anti-twist function. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] The implementation principle of a glass curtain wall corner node structure in an embodiment of the present application is as follows: a corner keel 1 is pre-buried inside the building wall, and a connecting frame 2 is used to fix two groups of glass curtain walls at the corner node and is connected to the corner keel 1; a fixing mechanism 3 is firmly connected by a fixing frame 31 set on the corner keel 1, a locking frame 32 in the middle of the connecting frame 2, and a locking bolt 33, and a plurality of locking reinforcement ribs 34 are distributed on both sides of the locking bolt 33, which effectively enhances the connection strength between the fixing frame 31 and the locking frame 32; the structure is reasonably designed and easy to operate, can ensure the stability and safety of the glass curtain wall corner node, and at the same time improve the bearing capacity of the overall structure, and is suitable for various building scenarios.

[0054] Example 2, reference Figure 3-Figure 4 and Figure 7-Figure 8 , the difference between this embodiment and the first embodiment is that: it also includes an anti-twist mechanism 4, which is used to limit the twisting of the corner keel 1 and the fixed frame 31. The anti-twist mechanism 4 includes a clamping frame 41 clamped on the outer surface of the fixed frame 31, and a plurality of adjustment slots 42 are provided on both sides of the clamping frame 41. An adjustment shaft 43 is provided for rotation in the adjustment slot 42. An anti-twist bearing plate 44 is provided on the outer surface of the adjustment shaft 43. A universal ball 45 is provided on the end of the bearing plate 44 away from the clamping frame 41. A supporting plate 46 is provided on the outer surface of the universal ball 45 corresponding to the inner surface of the glass curtain wall. The supporting plate 46 is in close contact with the inner surface of the glass curtain wall to prevent twisting. The rotating mechanism 4 can effectively limit the torsion of the corner keel 1 and the fixed frame 31 during the force-bearing process, thereby improving the stability of the entire glass curtain wall corner node structure; specifically, the cooperation between the clamping frame 41 and the fixed frame 31 ensures the initial positioning of the structure, and the design of the adjustment shaft 43 in the adjustment groove 42 allows angle adjustment according to actual installation requirements; the bearing plate 44, through the linkage effect of the universal ball 45 and the support plate 46, fits the support plate 46 tightly to the inner surface of the glass curtain wall, forming multi-point support, further enhancing the structure's anti-torsion ability, while reducing the stress concentration problem caused by torsion, and extending the service life of the structure.

[0055] refer to Figure 7 and Figure 8 In this embodiment, more specifically, the anti-twist mechanism 4 also includes a positioning plate 47. A plurality of slots 431 are provided from top to bottom on the side of the top of the adjusting shaft 43 away from the supporting plate 44. The positioning plate 47 is inserted into one of the slots 431. The top side of the positioning plate 47 is connected to the clamping frame 41. The cooperation between the positioning plate 47 and the slot 431 can effectively limit the rotation position of the adjusting shaft 43, thereby ensuring that the supporting plate 44 remains stable when subjected to force, avoiding structural deviation caused by external vibration or wind load; in addition, the connection between the positioning plate 47 and the clamping frame 41 further enhances the overall rigidity of the anti-twist mechanism 4, improves the reliability of the glass curtain wall corner node under complex working conditions, and extends the service life of the structure.

[0056] refer to Figure 7 In this embodiment, more specifically, an anti-skid rubber pad 461 is provided on the end surface of the supporting plate 46. The anti-skid rubber pad 461 is in close contact with the inner surface of the glass curtain wall. The provision of the anti-skid rubber pad 461 can increase the friction between the supporting plate 46 and the inner surface of the glass curtain wall, effectively preventing the supporting plate 46 from sliding on the inner surface of the glass curtain wall, thereby improving the stability of the entire structure; in addition, the close contact of the anti-skid rubber pad 461 can also play a certain buffering role, preventing the supporting plate 46 from causing hard damage to the glass curtain wall.

The inclined reinforcement plate 6 is connected to the inner wall of the corner keel 1 and the inner wall of the connecting frame 2 respectively. The setting of the inclined reinforcement plate 6 can effectively enhance the structural stability between the corner keel 1 and the connecting frame 2. Especially when the connecting frame 2 is subjected to force, the reinforcement effect of the triangular structure can significantly disperse and relieve stress concentration, thereby improving the bearing capacity of the corner node of the entire glass curtain wall and extending its service life.

[0058] Example 4, reference Figure 3 and Figure 5 The difference between this embodiment and the first embodiment is that an anti-deformation mechanism 7 is provided at the internal tail end of the corner keel 1, which is used to maintain anti-deformation force when the corner keel 1 is subjected to rotational force and extrusion force of the building wall. The anti-deformation mechanism 7 includes an anti-compression block 71 that supports the inner side of the corner keel 1, a threaded rod 72 for adjusting the anti-compression block 71, and a support sleeve 73 threadedly connected to the threaded rod 72.

A bearing block 75 is provided at one end of the bearing ring 74, and the bearing block 75 is connected to the internal tail end of the corner keel 1. The threaded rod 72 is adjusted in the inner thread of the support sleeve 73. The anti-deformation ability of the inner side of the corner keel 1 is increased by the anti-compression block 71, which can be used when the corner keel 1 is subjected to rotational force and extrusion of the building wall. When force is applied, the anti-compression block 71 directly presses against the inner side of the corner keel 1, providing strong anti-deformation support for the keel, effectively preventing the keel from deforming due to force, and ensuring the stability and safety of the building structure. By rotating the threaded rod 72, the pressure of the anti-compression block 71 on the inner side of the corner keel 1 can be accurately adjusted to adapt to different rotational forces and extrusion pressures, ensuring that the keel can maintain good anti-deformation performance under various working conditions. The connection between the bearing block 75 and the internal tail end of the corner keel 1 can evenly disperse the anti-deformation force transmitted by the threaded rod 72 to the keel, further enhancing the stability and bearing capacity of the entire anti-deformation mechanism 7. A pressure sensor 11 is provided on the inner wall of the corner keel 1 corresponding to the bearing block 75, which is used to monitor the deformation of the corner keel 1.
