[0004] Based on the above, the above solution has the following drawbacks: it cannot be adapted to glass curtain walls of different thicknesses. It requires inserting the clip into the slot and then filling the slot with a structural adhesive layer. After the structural adhesive layer is filled, it cannot be adapted to the installation of curtain wall glass of different thicknesses. Summary of the Invention

The fixing mechanism includes a first clamping plate and a second clamping plate. The first clamping plate is fixedly connected to an embedded part. Both the first clamping plate and the second clamping plate are provided with a clamping mechanism at one end near the glass curtain wall. The clamping mechanism clamps the two sides of the glass curtain wall. A vertical block is fixedly connected to the first clamping plate in the direction of the second clamping plate.

[0008] Optionally, an elastic connecting component is provided between the vertical block, the second clamping plate, and the rubber block. The elastic connecting component includes a foam rod and a rubber strip, and the two ends of the elastic connecting component abut against the vertical block and the glass curtain wall, respectively.

[0009] Optionally, the buffer mechanism includes an accordion strip and two second screws. The accordion strip is wavy, and the two second screws are respectively fixedly inserted through both ends of the accordion strip and fixedly connected to the first clamping plate.

[0023] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0024] This application discloses an integrated glass curtain wall expansion joint structure.

[0025] Reference Figure 1 and Figure 2The integrated glass curtain wall expansion joint structure includes two fixing mechanisms 1 and a buffer mechanism 2 disposed between the two fixing mechanisms 1. The fixing mechanism 1 includes a first clamping plate 12 and a second clamping plate 13. The first clamping plate 12 is fixed to the embedded part. The first clamping plate 12 and the second clamping plate 13 extend outward and are fixed with a clamping mechanism 4, which clamps the glass curtain wall. A vertical block 121 is welded to the side wall of the first clamping plate 12 facing the second clamping plate 13. A third bolt 18 is passed through the end of the vertical block 121 and fixed to the second clamping plate 13 by the third bolt 18. A third nut 181 is sleeved on the third bolt 18. A rubber gasket 46 is provided at the abutment of the end of the vertical block 121 and the second clamping plate 13 to reduce the mutual compression and deformation of the vertical block 121 and the second clamping plate 13.

[0026] The buffer mechanism 2 includes a gusseted rubber strip 21, a first screw 14, and two second screws 15. The gusseted rubber strip 21 has a wavy structure, providing deformable space and better sealing. The gusseted rubber strip 21 is parallel to the extension direction of the expansion joint. The two second screws 15 fix both ends of the gusseted rubber strip 21 to the first clamping plate 12. Two first connecting plates 16, parallel to the extension direction of the expansion joint, are provided on the side of the gusseted rubber strip 21 facing the embedded part. The two first connecting plates 16 are arranged along the length of the gusseted rubber strip 21, and the ends of the two first connecting plates 16 near the curtain wall are fixed to the two first clamping plates 12 by the second screws 15. A protective plate 17 is provided on the side of the gusseted rubber strip 21 away from the first connecting plate 16, and one end of the protective plate 17 is fixed to the first clamping plate 12 by the first screw 14. Meanwhile, the protective plate 17 is placed on the side of the accordion rubber strip 21 away from the first connecting plate 16, which can reduce the aging of the rubber caused by direct sunlight, wind and rain, and extend the service life of the accordion rubber strip 21.

[0027] Reference Figure 1 and Figure 2 One of the first connecting plates 16 has an integrally formed U-shaped recess 161 at the end opposite to the first screw 14. The recess 161 is recessed towards the side opposite to the accordion strip 21. The other first connecting plate 16 has an integrally formed folding block 162 at its end. The folding block 162 is perpendicular to the first connecting plate 16 and is located inside the recess 161. A movable gap is left between the folding block 162 and the recess 161 to reduce collisions caused by movement due to the thermal expansion and contraction of the accordion strip 21.

[0028] Reference Figure 1 and Figure 2A rubber body 122 is provided between the first connecting plate 16 and the first clamping plate 12. The rubber body 122 has mounting holes for inserting the first screw 14 and the second screw 15. During installation, the first clamping plate 12 and the second clamping plate 13 can be used to clamp the glass curtain wall, thereby driving the extension block 41 to clamp the glass curtain wall and abutting the arc-shaped rotating rod 42 against the edge of the glass curtain wall. When the position of the third nut 181 moves downward, the second clamping plate 13 will also move downward by a corresponding distance. By rotating and adjusting the position of the third nut 181 on the third bolt 18, the space between the first clamping plate 12 and the second clamping plate 13 can be adjusted, thereby clamping and fixing glass curtain walls of different thicknesses. When the second clamping plate 13 moves downward, the first screw 14 can be rotated in the direction of movement of the second clamping plate 13, thereby moving the protective plate 17 at the same time, so that the second clamping plate 13 always abuts against the protective plate 17, reducing the inflow of rainwater and accelerating the rusting of parts.

[0029] Utilizing the elasticity of the rubber body 122, when the gap between the first clamping plate 12 and the first connecting plate 16 shrinks, the volume of the rubber body 122 can be compressed to fix it; when the gap between the first clamping plate 12 and the first connecting plate 16 expands, it can also fully fill the gap between the first clamping plate 12 and the first connecting plate 16, reducing air inflow and accelerating rusting.

[0030] Reference Figure 1 and Figure 2 The second clamping plate 13 is provided with a detachable aluminum alloy cover 131, which can reduce the rusting of parts caused by rainwater soaking the third bolt 18, the third nut 181 and the second clamping plate 13, and extend the service life.

[0031] Reference Figure 1 , Figure 2 and Figure 3 Elastic connecting components 111 are provided between the first clamping plate 12, the second clamping plate 13 and the glass curtain wall. The first clamping plate 12, the second clamping plate 13 and the first connecting plate 16 and the protective plate 17 are also provided with the above-mentioned elastic connecting components 111. The elastic connecting components 111 include foam rods 112 and rubber strips 113, which prevent the first clamping plate 12, the second clamping plate 13 and the glass curtain wall from directly abutting and squeezing each other, and also prevent the first connecting plate 16 and the first nut 141 from directly abutting and squeezing each other.

[0032] Reference Figure 1 , Figure 2 and Figure 3The clamping mechanism 4 includes extension blocks 41 respectively disposed on the first clamping plate 12 and the second clamping plate 13. Each extension block 41 has a receiving groove. A crossbar 43 is rotatably connected to the groove via bearings. An arc-shaped rotating rod 42 is fixed on the crossbar 43, with both ends extending out of the receiving groove. A rubber pad 45 is provided at the end of the arc-shaped rotating rod 42 facing away from the first clamping plate 12, and the rubber pad 45 abuts against the edge of the extension block 41. There is a movement gap between the end of the arc-shaped rotating rod 42 near the foam rod 112 and the edge of the extension block 41. A rubber block 44 abuts against the end of the curtain wall, and the other end of the rubber block 44 abuts against the arc-shaped rotating rod 42. The use of rubber material for contact with the glass curtain wall can prevent glass breakage due to uneven force or the squeezing and collision between the extension block 41 and the glass curtain wall.

[0033] When the glass curtain wall retracts into the expansion joint, the rubber block 44 simultaneously retracts towards the expansion joint. The rubber block 44 drives the tail end of the arc-shaped rotating rod 42 to move, and one end of the arc-shaped rotating rod 42 connected to the rubber pad 45 moves towards the glass curtain wall. Even when the glass curtain wall retracts into the expansion joint, it remains clamped. Due to the narrow structure of the expansion joint, the clearance within it is also very small, preventing any loosening between the glass curtain wall and the clamping mechanism 4.

[0034] This application also discloses a construction method for an integrated glass curtain wall expansion joint structure, including the following steps: Step A: Fix the first clamping plate 12 to the embedded part using pre-embedded bolts.

[0035] Step B: By inserting the first screw 14 and the second screw 15, fix the accordion strip 21, the first connecting plate 16 and the protective plate 17 to the first clamping plate 12.

[0036] Step C: The third bolt 18 passes through the joint between the vertical block and the second clamping plate 13, and the third nut 181 is tightened to fix the first clamping plate 12 and the second clamping plate 13. The horizontal bar inside the connecting extension block 41 is rotated to fix the arc-shaped rotating rod 42 to the horizontal bar 43. Through the clamping action of the first clamping plate 12 and the second clamping plate 13, the extension block 41 is driven to clamp and the rubber pad 45 at one end of the arc-shaped rotating rod 42 is pressed against the glass curtain wall to install the glass curtain wall.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
