DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] In order to solve the technical problem that the expansion joint of the glass curtain wall cannot isolate the air flow, the present invention provides a curtain wall node structure, which can isolate the air flow at the expansion joint of the glass curtain wall.

[0021] It should be noted that the curtain wall node structure described in the present invention is used for but not limited to glass curtain walls, etc. For the convenience of explanation, in the present invention, only the application of the curtain wall node structure to the glass curtain wall is used as an example for explanation, and the principle of applying the curtain wall node structure to other types of equipment is substantially the same as the principle applied to the glass curtain wall, which will not be repeated here.

[0022] See also Figure 1 , Figure 11 is a structural schematic diagram of a curtain wall node structure in an embodiment of the present invention. The curtain wall node structure includes two glass curtain walls 1 and a sealing mechanism 2. The two glass curtain walls 1 are configured and fixed to a building 6, and a telescopic gap is formed between the two glass curtain walls 1; the sealing mechanism 2 is arranged in the telescopic gap, and includes a first fixing member 21, a second fixing member 22 and a sealing member 23. The first fixing member 21 and the second fixing member 22 are respectively connected to the two glass curtain walls 1, and a first gap 21a, a second gap 21b and a third gap 21c that are connected in sequence are formed between the first fixing member 21 and the second fixing member 22. The second gap 21b is perpendicular to the first gap 21a and the third gap 21c. The sealing member 23 is arranged in the second gap 21b, and one side is connected to the second fixing member 22, and the other side elastically fits the first fixing member 21.

[0023] Specifically, by setting the sealing mechanism 2, the sealing mechanism 2 is set at the expansion gap of the glass curtain wall 1, and by forming the first gap 21a, the second gap 21b and the third gap 21c that are connected in sequence between the first fixing member 21 and the second fixing member 22, so that when an expansion joint is formed between the two glass curtain walls 1, the first gap 21a and the third gap 21c that are perpendicular to the second gap 21b can form a bent gap to prevent the fluid from flowing through the gap; at the same time, the seal is set in the second gap 21b, and when foreign impurities enter the second gap 21b, they need to pass through the bent gap, reducing the contact of the seal 23 with foreign impurities; the seal 23 is connected to the second fixing member 22 and elastically fits the first fixing member 21, and can block the second gap 21b to prevent air flow between the inside and outside of the building 6. Secondly, when the building 6 is expanded and contracted at the expansion joint, the first fixing member 21 will move relative to the second fixing member 22. At this time, the seal 23 still elastically fits the first fixing member 21, and can adaptively seal the expansion joint when the building 6 is expanded and contracted.

[0024] It should be understood that the glass curtain wall 1 can be directly fixed to the building 6, or can be indirectly fixed to the building 6 via other structures, such as Figure 2 and Figure 3 As shown, specifically, in one of the embodiments, the curtain wall node structure also includes two fixing mechanisms 3, the fixing mechanism 3 includes embedded parts 31 and steel structures 32, the embedded parts 31 are configured to be fixedly built into the building 6, and the steel structure 32 is connected to the embedded parts 31; the two glass curtain walls 1 are respectively connected to the two steel structures 32, and are fixed to the building 6 through the steel structures 32.

[0025] The embedded component 31 is fixedly built into the building 6 and connected to the solidified building 6 as a whole. The steel structure 32 realizes the connection between the embedded component 31 and the glass curtain wall 1 and can support the glass curtain wall 1 .

[0027] In order to further seal the expansion joint, Figure 3 As shown, in one embodiment, the sealing mechanism 2 further includes a sealing strip 24, and the two sides of the sealing strip 24 are respectively connected to the steel structures 32 in the two fixing mechanisms 3. It should be understood that the sealing strip 24 and the steel structure 32 can be fixedly connected or detachably connected by bolts and screws.

[0028] By further arranging a sealing strip 24 on the basis of the sealing member 23, the sealing strip can further seal the expansion gap and further enhance the sealing effect.

[0029] like Figure 2 and Figure 3 As shown, in one embodiment, the embedded part 31 includes a first threaded steel bar 311 and a second threaded steel bar 312, one end of the first threaded steel bar 311 is built into the building 6, the second threaded steel bar 312 is built into the building 6 and arranged in parallel with the first threaded steel bar 311, the second threaded steel bar 312 is connected to the first threaded steel bar 311, and the steel structure 32 is connected to the other end of the first threaded steel bar 311. It should be understood that the embedded part 31 can also be other structures.

[0036] Two first protection pads 43 are arranged on both sides of the glass curtain wall 1, and are arranged between the first connection part 41 and the glass curtain wall 1, and between the second connection part 42 and the glass curtain wall 1. The glass curtain wall 1 indirectly contacts the second connection part 42 and the first connection part 41 through the two first protection pads 43, which can play a role of buffering and shock absorption, and can protect the glass curtain wall 1.

[0037] It should be understood that the first protection pad 43 can be a rubber belt, a silicone pad, etc.

[0038] It should be understood that another glass curtain wall 1 may also be connected to the steel structure 32 using the first connecting mechanism 4, or may be connected to the steel structure 32 using a different structure, such as Figure 5 As shown, in one embodiment, the curtain wall node structure further includes a second connecting mechanism 5, the second connecting mechanism 5 is connected to the steel structure 32, a slot is formed on one side of the second connecting mechanism 5, and the other glass curtain wall 1 is inserted into the slot.

[0041] like Figure 6 and Figure 7 As shown, in one embodiment, the sealing mechanism 2 further includes a reinforcing member 25, the reinforcing member 25 includes a crossbeam 251 and an angle iron 252, the crossbeam 251 is connected to the steel structure 32, and the angle iron 252 is connected to the crossbeam 251 and the second folding plate 213. By providing the crossbeam 251 and the angle iron 252, the structure of the first fixing member 21 can be strengthened, and the stability of the first fixing member 21 can be enhanced.

[0042] The cross beam 251 and the angle iron 252, and the angle iron 252 and the second folding plate 213 can be connected by welding, screw connection or the like.

[0043] like Figure 6 As shown, in one embodiment, the sealing member 23 is an elastic sealing strip, one side of the elastic sealing strip is fixed to the second fixing member 22 , and the other side of the elastic sealing strip elastically abuts against the first fixing member 21 .

[0044] By providing an elastic sealing strip, the elastic sealing strip is elastic and can provide elastic force to elastically fit the first fixing member 21. It should be understood that the material of the elastic sealing strip can be rubber, silicone, latex, etc.

[0045] After a certain period of use, materials such as rubber, silicone and latex will age and lose their elasticity, resulting in sealing failure. Figure 7 , Figure 8 and Fig. 9 As shown, in one embodiment, the sealing member 23 includes a fixed portion 231, a rotating portion 232, a sealing portion 233 and an elastic portion 234. The fixed portion 231 is connected to the second fixed member 22, the rotating portion 232 is rotatably connected to the fixed portion 231, one side of the sealing portion 233 is connected to the rotating portion 232, and the other side abuts against the first fixed member 21. The elastic portion 234 connects the fixed portion 231 and the rotating portion 232, and is used to provide elastic force for the sealing portion 233 to elastically fit the first fixed member 21.

[0046] One side of the sealing portion 233 is rotatably connected to the rotating portion 232, and the elastic portion 234 can provide elastic force, so that the sealing portion 233 elastically fits the first fixing member 21, thereby achieving sealing of the second gap 21b. In this embodiment, sealing is performed by the fixing portion 231, the rotating portion 232, the sealing portion 233 and the elastic portion 234, and the sealing process does not rely on the elastic force of the rubber, thereby avoiding aging and failure of the sealing member 23.

[0047] In order to realize the rotation connection between the fixed part 231 and the rotating part 232, it is also necessary to seal the connection between the fixed part 231 and the rotating part 232. Figure 7 , Figure 8 and Fig. 9 In one embodiment shown in the figure, a protrusion 235 is formed on one side of the fixing portion 231 facing the first fixing member 21 , and the protrusion 235 is cylindrical. A groove is formed in the rotating portion 232 relative to the protrusion 235 , and the rotating portion 232 can be rotatably mounted on the protrusion 235 through the groove.

[0048] In this embodiment, the rotating part 232 is sleeved on the protrusion 235 through the groove, thereby realizing the rotational connection between the rotating part 232 and the protrusion 235. At the same time, through the cooperation between the groove and the protrusion 235, the connection between the rotating part 232 and the fixed part 231 can be sealed.

[0049] Since the rotating portion 232 can be rotatably sleeved on the cylindrical protrusion 235, the rotating portion 232 can slide down along the axial direction of the protrusion 235. Figure 7 , Figure 8 and Fig. 9 In one embodiment shown in the figure, the protrusion 235 is provided with at least one rotation groove, and the rotation portion 232 is formed with a rotation piece 236 relative to the rotation groove. The rotation piece 236 is inserted into the rotation groove and can rotate along the circumferential direction of the protrusion 235 .

[0050] By providing a rotating groove and a rotating sheet 236, when the rotating part 232 rotates, the rotating sheet 236 is driven to rotate relative to the protrusion 235, and the rotating sheet 236 rotates relative to the rotating groove; and the rotating sheet 236 is inserted into the rotating groove, which can limit the axial movement of the rotating part 232 along the protrusion 235, thereby realizing the axial limitation of the rotating part 232. At the same time, since the rotating sheet 236 and the rotating groove are located between the rotating part 232 and the protrusion 235, it is possible to prevent the rotating sheet 236 and the rotating groove from contacting external impurities and affecting the rotation damping of the rotating part 232.

[0051] In order to prevent the rotating part 232 from separating from the protrusion 235, in one embodiment, the protrusion 235 is provided with a countersunk hole along the axial direction, and the rotating piece 236 is provided with a through hole relative to the countersunk hole; the sealing member 23 also includes a latch 237, which is inserted into the countersunk hole and the through hole.

[0052] The latch 237 passes through the rotating piece 236 through the through hole. The latch 237 can confine the rotating piece 236 in the rotating groove, thereby preventing the rotating piece 236 and the rotating portion 232 from being separated from the protrusion 235 .

[0053] It should be understood that the elastic portion 234 may be a spring, an elastic strip, an elastic block, etc. Figure 7 , Figure 8 and Fig. 9 As shown, in one embodiment, the countersunk hole includes a connected fixing hole and a threaded hole, the inner diameter of the threaded hole is larger than the inner wall of the fixing hole, the pin 237 can be rotatably inserted in the fixing hole, the cross-section of the pin 237 is square, the through hole is a square hole and is fitted on the pin 237, the sealing member 23 also includes a retaining ring 238 and a sealing plug 239, the retaining ring 238 is connected to the pin 237 and is built into the threaded hole, the outer diameter of the retaining ring 238 is larger than the inner diameter of the fixing hole, the sealing plug 239 is threadedly connected to the retaining ring 238, the elastic portion 234 is a torsion spring, the torsion spring is built into the threaded hole, one end of the torsion spring is connected to the retaining ring 238 and the other end is connected to the sealing plug 239, one end of the torsion spring is connected to the rotating portion 232 via the retaining ring 238, the pin 237 and the rotating sheet 236, and the other end of the torsion spring is connected to the fixed portion 231 via the sealing plug 239.

[0054] During the installation process, the rotating piece 236 is first inserted into the rotating groove, and the rotating part 232 is sleeved on the protrusion 235, and then the pin 237 is inserted into the fixing hole, and the pin 237 passes through the rotating piece 236 through the through hole, and then the sealing plug 239 is threadedly connected to the threaded hole. During the threaded connection process, the sealing plug 239 will twist the torsion spring, so that the torsion spring forms an elastic restoring force, and the elastic restoring force of the torsion spring can drive the retaining ring 238 and the pin 237 to rotate, and the rotating pin 237 can apply elastic force to the rotating piece 236 and the rotating part 232, so as to apply elastic restoring force to the rotating part 232; at the same time, due to the self-locking of the sealing plug 239 and the threaded hole, the elastic force can be maintained. At the same time, the sealing plug 239, the elastic part 234 and the pin 237 are all built into the countersunk hole, which can prevent impurities from contacting the elastic part 234 and the pin 237 and corroding the elastic part 234 and the pin 237, so that the elastic part 234 can provide elastic restoring force for a long time.

[0055] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention.
