[0002] Glass curtain walls are beautiful and have good light transmittance. Their application in high-end commercial buildings is increasing. The Chinese utility model patent with authorization announcement number CN218843472U discloses a glass curtain wall construction node structure. The node structure is used to seal and connect two adjacent glass curtain wall units, and connect decorative parts on the outside of the connection seam between the two glass curtain walls. The glass curtain wall construction node structure includes a fixed frame and a decorative strip connecting plate for connecting glass panels. The decorative strip connecting plate includes a first fixed plate segment, a connecting plate segment and a second fixed plate segment arranged in sequence. The first fixed plate segment is fixedly connected to the butt surface of one of the two fixed frames, and the second fixed plate segment is attached to the butt surface of the two fixed frames. The butt joint extends outward from the butt joint and connects the decorative parts. To ensure the sealing of the butt joint of the two fixed frames, it is necessary to set oppositely arranged sealing strips at the butt joint surfaces of the two fixed frames. The sealing strips are located between the first fixed plate segment and the second fixed plate segment. Since the connecting plate segment is attached to the butt joint surface of the fixed frame, the sealing strips are located on the butt joint surface of the fixed frame. Therefore, before arranging the sealing strips on the fixed frame connected to the fixed plate segment, it is necessary to first cut the sealing strips into multiple sections, and then install the multiple sections of sealing strips on the fixed frame connected to the fixed plate segment respectively, and arrange the adjacent sealing strips at both ends at a spacing equal to the width of the connecting plate segment for the connecting plate segment to pass through.

[0038] like Figures 1 to 6As shown, a preferred embodiment of a glass curtain wall unit connection node of the present invention includes a first fixing frame 1, a second fixing frame 2, a first sealing strip 31, a second sealing strip 32, a connecting piece 4 and a decorative piece 5; the arrangement direction of the two curtain wall units 100 is defined as a first direction, the direction from one end of the two curtain wall units 100 facing indoors to the other end facing outdoors is defined as a second direction, and the direction perpendicular to the first direction and the second direction is defined as a third direction; in this embodiment, the two curtain wall units 100 are arranged at intervals on the left and right, the first direction is from left to right, the second direction is from indoors to outdoors, and the third direction is from top to bottom; in the first direction, the first fixing frame 1 and the second fixing frame 2 are arranged at intervals on the left and right, and the first fixing frame 1 faces the second direction. One end of the second fixed frame 2 is provided with a first connecting structure 111; the first sealing strip 31 is connected to the end of the first fixed frame 1 facing the second fixed frame 2, and the first connecting structure 111 and the first sealing strip 31 are arranged in sequence in the second direction; the second sealing strip 32 is connected to the end of the second fixed frame 2 facing the first fixed frame 1, and the second sealing strip 32 and the first sealing strip 31 are pressed and sealed in the first direction; the length directions of the first sealing strip 31 and the second sealing strip 32 are arranged along the third direction, the width directions of the first sealing strip 31 and the second sealing strip 32 are arranged along the second direction, the thickness directions of the first sealing strip 31 and the second sealing strip 32 are arranged along the first direction, and the end of the first sealing strip 31 facing the second sealing strip 32 is pressed against the second sealing strip 31 32 abuts against one end of the first sealing strip 31 and is compressed due to the pressure applied by each other along the first direction. The connecting member 4 includes a first connecting section 41, a transition section 42 and a second connecting section 43 arranged in sequence along the second direction; the first connecting section 41 is connected to the first connecting structure 111; the second connecting section 43 is connected to the decorative member 5; the first fixing frame 1, the transition section 42 and the second fixing frame 2 are arranged in sequence along the first direction; the length direction of the transition section 42 is along the second direction, and the length direction of the first sealing strip 31 and the second sealing strip 32 is along the third direction. The first sealing strip 31 and the transition section 42 form a cross structure. In this embodiment, the transition section 42 is arranged at intervals from the first fixing frame 1, and the first sealing strip 31 is compressed by the transition section 42 It is arranged in the gap between the transition section 42 and the first fixed frame 1, so there is no need to cut the first sealing strip 31 at the position where the transition section 42 passes. The second sealing strip 32 also forms a cross structure with the transition section 42. The second sealing strip 32 is compressed by the transition section 42 and is arranged in the gap between the transition section 42 and the second fixed frame 2. Therefore, there is no need to cut the second sealing strip 32 at the position where the transition section 42 passes. The transition section 42 is located between the first sealing strip 31 and the second sealing strip 32. Under the extrusion of the first sealing strip 31 and the second sealing strip 32, the intersection between the transition section 42 and the first sealing strip 31 and the second sealing strip 32 has good sealing performance, and there is no need to cut the first sealing strip 31, which greatly improves the construction efficiency of the glass curtain wall.

[0039] Furthermore, in this embodiment, both the first sealing strip 31 and the second sealing strip 32 are hollow sealing strips. Hollow sealing strips have a larger compression space and a larger elastic recovery range, which ensures that the transition section 42 can smoothly compress the first and second sealing strips 31, 32 without damaging them and pass through the joint between the first and second sealing strips 31, 32.

[0040] In this embodiment, the first connecting structure 111 is a first card slot that passes through the first fixed frame 1 along the third direction. The first connecting section 41 can enter the first card slot through the port of the first card slot and slide in the first card slot. After adjusting the first connecting section 41 to the desired position, the first connecting section 41 and the slot wall of the first card slot are connected using self-tapping screws to fix the first connecting section 41 on the first fixed frame 1.

[0041] To further enhance the connection strength between the connector 4 and the first fixed frame 1, in this embodiment, the transition section 42 includes a clamping section 421, a first bent section 422, and a third connecting section 423, arranged sequentially along the second direction.

One end of the first bent section 422 is connected to the end of the clamping section 421 facing away from the first connection end, while the other end extends obliquely toward the first fixed frame 1 and connects to the third connecting section 423. The third connecting section 423 abuts and connects to the end of the first fixed frame 1 facing the second fixed frame 2. The second connecting section 43 is connected to the end of the third connecting section 423 facing away from the first bent section 422. The provision of the third connecting section 423 provides two connection nodes for the connector 4 to the first fixed frame 1 along its length, thereby enhancing the connection strength of the connector 4 to the first fixed frame 1.

[0042] Specifically, in this embodiment, the glass curtain wall unit connection node includes a first fastener 61, and the second connecting section 43 is fastened to the first fixed frame 1 via the first fastener 61. The first fixed frame 1 includes a frame body 11 and a connecting plate 12. In the second direction, the frame body 11 and the connecting plate 12 overlap, and the first fastener 61 sequentially connects the second connecting section 43, the overlapping end of the connecting plate 12, and the overlapping end of the frame body 11. The first fixed frame 1 is configured as a separate frame body 11 and a connecting plate 12. Both the frame body 11 and the connecting plate 12 are aluminum profiles, which facilitates the processing and forming of the first fixed frame 1. The first fastener 61 is used to connect the connecting plate 12, the connector 4, and the frame body 11, further improving the installation efficiency of the glass curtain wall unit connection node of this embodiment.

[0043] In this embodiment, the connecting member 4 further includes a second bent section 424, and the second connecting section 43 is connected to the third connecting section 423 via the second bent section 424, so that the first fixing frame 1, the second connecting section 43, and the second fixing frame 2 are arranged in sequence and spaced apart in the first direction. Specifically, the extension direction of the second bent section 424 is opposite to the extension direction of the first bent section 422. The first bent section 422, the third connecting section 423, and the second bent section 424 form an isosceles trapezoidal structure, with the third connecting section 423 located at the top of the isosceles trapezoidal structure. This arrangement enables the second connecting section 43 to be located in the middle of the interval between the first fixing frame 1 and the second fixing frame 2 in the first direction. As a result, when the second connecting section 43 connects to the middle of the decorative member 5, the decorative member 5 can be centered relative to the first fixing frame 1 and the second fixing frame 2 in the first direction.

[0044] To further improve the sealing performance of the glass curtain wall unit connection node of the present invention, in this embodiment, the glass curtain wall unit connection node further includes a third sealing strip 33 and a fourth sealing strip 34; the third sealing strip 33 is connected to one end of the first fixing frame 1 facing the second fixing frame 2, the first sealing strip 31 and the second sealing strip 32 are spaced apart in the second direction, the fourth sealing strip 34 is connected to the second fixing frame 2, and the third sealing strip 33 and the fourth sealing strip 34 are pressed and sealed in the first direction; the second connecting section 43 is arranged between the first sealing strip 31 and the second sealing strip 32; the third sealing strip 33 is compressed by the second connecting section 43 and is passed through the gap between the second connecting section 43 and the first fixing frame 1; the fourth sealing strip 34 is compressed by the second connecting section 43 and is passed through the gap between the second connecting section 43 and the second fixing frame 2. The arrangement of the third sealing strip 33, the fourth sealing strip 34 and the second connecting section 43 is similar to the arrangement of the clamping section 421, the first sealing strip 31 and the second sealing strip 32, which not only ensures the sealing of the second connecting section 43 by the third sealing strip 33 and the fourth sealing strip 34, but also facilitates efficient construction.

[0045] To ensure that the second connecting section 43 can smoothly compress the third sealing strip 33 and the fourth sealing strip 34 without damaging the third sealing strip 33 and the fourth sealing strip 34 and pass through the butt joint between the third sealing strip 33 and the fourth sealing strip 34, the third sealing strip 33 and the fourth sealing strip 34 are both hollow sealing strips.

[0046] In this embodiment, the glass curtain wall unit connection node further includes a fastening bolt 62, a fifth sealing strip 35, and a sixth sealing strip 36; the connecting member 4 is a plate-shaped profile, and the second connecting section 43 is used to connect to one end of the decorative member 5 and has a wedge-shaped portion 431. In the second direction, the end of the wedge-shaped portion 431 with a smaller cross-section is arranged close to the first connecting section 41; a wedge-shaped groove 51 is provided through the middle of the end of the decorative member 5 facing the first fixing frame 1 and the second fixing frame 2 along the third direction; the fifth sealing strip 35 and the sixth sealing strip 36 are both connected to the end of the decorative member 5 facing the first fixing frame 1 and the second fixing frame 2. In the second direction, the fifth sealing strip 35 is arranged opposite to the first glass plate 81 connected to the first fixing frame 1, and the sixth sealing strip 36 is arranged opposite to the second glass plate 82 connected to the second fixing frame 2; the wedge portion 4 31 is matched and inserted into the wedge-shaped groove 51; one of the groove wall and the wedge-shaped portion 431 of the wedge-shaped groove 51 is provided with a bolt hole 432, and the other is provided with a slide groove 52 arranged along the second direction, and the fastening bolt 62 passes through the slide groove 52 and the bolt hole 432 and is connected with a nut 63. After tightening the nut 63 and the fastening bolt 62, under the action of the wedge-shaped portion 431 and the wedge-shaped groove 51, the decorative piece 5 will move in the second direction toward the first glass plate 81 and the second glass plate 82, so that the fifth sealing strip 35 presses against the first glass plate 81 and the sixth sealing strip 36 presses against the second glass plate 82, ensuring the sealing effect of the decorative piece 5 on the gap between the first fixing frame 1 and the second fixing frame 2, and enabling the first glass plate 81 and the second glass plate 82 to be stably connected to the first fixing frame 1 and the second fixing frame 2.

[0047] To further improve the sealing performance of the glass curtain wall unit connection node of this embodiment, the glass curtain wall unit connection node of this embodiment further includes a plug-in mechanism.
