Description

Technical Field

[0001] This invention relates to the field of glass curtain wall technology, and more specifically to a curtain wall node structure. Background Technology

[0002] A glass curtain wall is a building envelope or decorative structure composed of metal components and glass panels.

[0003] Because different components of a building may expand and contract with temperature changes, expansion joints need to be installed at designated locations on the building to allow for expansion and contraction. Since glass curtain walls are fixed to the building, expansion joints also need to be installed at the building's expansion joints. The current common practice is to install two sliding connecting plates at the expansion joints to seal them.

[0004] However, gaps are easily formed between the sliding connection plates. The presence of these gaps can cause convection between the interior and exterior of the building, failing to isolate the airflow and thus failing to achieve the insulation effect of the glass curtain wall. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a curtain wall node structure to solve the technical problem that the expansion joints of glass curtain walls cannot isolate airflow in the prior art.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] This invention provides a curtain wall node structure, comprising:

[0008] Two glass curtain walls are fixed to the building, and an expansion gap is formed between the two glass curtain walls; and

[0009] A sealing mechanism, disposed in the expansion gap, includes a first fixing member, a second fixing member, and a sealing member. The first fixing member and the second fixing member are respectively connected to the two glass curtain walls. A first gap, a second gap, and a third gap are formed between the first fixing member and the second fixing member in sequence. The second gap is perpendicular to the first gap and the third gap. The sealing member is disposed in the second gap, and one side is connected to the second fixing member, while the other side is elastically fitted to the first fixing member.

[0010] In one embodiment, the curtain wall node structure further includes two fixing mechanisms, each including an embedded part and a steel structure. The embedded part is fixedly built into the building, and the steel structure is connected to the embedded part. The two glass curtain walls are respectively connected to the two steel structures and fixed to the building via the steel structures.

[0011] In one embodiment, the seal further includes a sealing strip, with its two sides respectively connected to the steel structures in the two fixing mechanisms.

[0012] In one embodiment, the embedded part includes a first threaded steel bar and a second threaded steel bar, one end of the first threaded steel bar is embedded in the building, the second threaded steel bar is embedded in the building and arranged in parallel with the first threaded steel bar, the second threaded steel bar is connected to the first threaded steel bar, and the steel structure is connected to the other end of the first threaded steel bar.

[0013] In one embodiment, the curtain wall node structure further includes a first connecting mechanism, which includes a first connecting part and a second connecting part. The first connecting part is connected to the steel structure, and the second connecting part is connected to the first connecting part, with an installation gap formed between the second connecting part and the first connecting part. An end of the glass curtain wall is inserted into the installation gap and connected to the steel structure via the first connecting part and the second connecting part.

[0014] In one embodiment, a first mounting groove is provided on the opposite side of the second connecting part and the first connecting part in the mounting gap. The first connecting mechanism also includes two first protective pads, which are respectively engaged in the two mounting grooves. One first protective pad is disposed between the first connecting part and the glass curtain wall, and the other first protective pad is disposed between the second connecting part and the glass curtain wall.

[0015] In one embodiment, the sealing element includes a fixing part, a rotating part, a sealing part, and an elastic part. The fixing part is connected to the second fixing element, the rotating part is rotatably connected to the fixing part, one side of the sealing part is connected to the rotating part and the other side abuts against the first fixing element, and the elastic part is connected to the fixing part and the rotating part to provide elastic force for the sealing part to elastically conform to the first fixing element.

[0016] In one embodiment, the fixing part has a protrusion on the side facing the first fixing member, the protrusion being cylindrical, and the rotating part has a groove relative to the protrusion, and is rotatably fitted onto the protrusion through the groove.

[0017] In one embodiment, the protrusion has at least one rotating groove, and the rotating part has a rotating plate formed relative to the rotating groove. The rotating plate is inserted into the rotating groove and is capable of rotating around the circumference of the protrusion.

[0018] In one embodiment, the protrusion has a countersunk hole along the axial direction, and the rotating plate has a through hole relative to the countersunk hole;

[0019] The sealing element also includes a pin, which is inserted into the countersunk hole and the through hole.

[0020] Compared with the prior art, the present invention provides a curtain wall node structure. By setting a sealing mechanism at the expansion gap of the glass curtain wall, a first gap, a second gap, and a third gap are formed sequentially between the first and second fixing members. This allows the expansion joint to be formed between the two glass curtain walls, while the first and third gaps, perpendicular to the second gap, can form a bent gap, hindering fluid flow through the gap. At the same time, the seal is set in the second gap, so external impurities must pass through the bent gap when entering the second gap, reducing the seal's contact with external impurities. The seal is connected to the second fixing member and elastically fits the first fixing member, which can seal the second gap and prevent air flow between the inside and outside of the building. Furthermore, when the building expands or contracts at the expansion joint, the first fixing member will move relative to the second fixing member. At this time, the seal still elastically fits the first fixing member, which can adaptively seal the expansion joint when the building expands or contracts. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0038] To address the technical problem of airflow not being effectively isolated at expansion joints in glass curtain walls, this invention provides a curtain wall node structure that can isolate airflow at expansion joints in glass curtain walls.

[0039] It should be noted that the curtain wall node structure described in this invention is used in, but not limited to, glass curtain walls. For ease of explanation, this invention will only use the application of the curtain wall node structure in glass curtain walls as an example. The principle of applying the curtain wall node structure to other types of equipment is essentially the same as that applied to glass curtain walls, and will not be elaborated here.

[0040] Please see Figure 1 , Figure 1This is a schematic diagram of a curtain wall node structure in one 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 fixed to the building 6, and an expansion gap is formed between the two glass curtain walls 1. The sealing mechanism 2 is disposed in the expansion 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. A first gap 21a, a second gap 21b and a third gap 21c are formed between the first fixing member 21 and the second fixing member 22 in sequence. The second gap 21b is perpendicular to the first gap 21a and the third gap 21c. The sealing member 23 is disposed in the second gap 21b, and one side is connected to the second fixing member 22 and the other side is elastically attached to the first fixing member 21.

[0041] Specifically, by setting a sealing mechanism 2, which is located at the expansion gap of the glass curtain wall 1, a first gap 21a, a second gap 21b, and a third gap 21c are formed sequentially between the first fixing member 21 and the second fixing member 22. This allows the expansion joint to be formed between the two glass curtain walls 1, while the first gap 21a and the third gap 21c, which are perpendicular to the second gap 21b, can form a bent gap, preventing fluid from flowing through the gap. At the same time, the seal is set at the second gap 21b, so that external impurities need to pass through the bent gap when entering the second gap 21b, reducing the contact between the seal 23 and external impurities. The seal 23 is connected to the second fixing member 22 and elastically fits the first fixing member 21, which can seal the second gap 21b and prevent air flow between the inside and outside of the building 6. Furthermore, when the building 6 expands and contracts 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, which can adaptively seal the expansion joint when the building 6 expands and contracts.

[0042] It should be understood that the glass curtain wall 1 can be directly fixed to the building 6, or it can be indirectly fixed to the building 6 through other structures, such as... Figure 2 and Figure 3 As shown, specifically, in one embodiment, the curtain wall node structure further includes two fixing mechanisms 3. The fixing mechanism 3 includes embedded parts 31 and steel structures 32. The embedded parts 31 are fixedly built into the building 6, and the steel structures 32 are connected to the embedded parts 31. The two glass curtain walls 1 are respectively connected to the two steel structures 32 and fixed to the building 6 through the steel structures 32.

[0043] The embedded part 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 part 31 and the glass curtain wall 1 and can support the glass curtain wall 1.

[0044] It should be understood that in the two fixed mechanisms 3, the shapes of the steel structures 32 can be the same or different. The steel structures 32 are formed by welding or bolting one or more of the following: channel steel, I-beam, galvanized steel pipe, galvanized steel plate, etc.

[0045] To further seal the expansion joints, therefore, such as Figure 3 As shown, in one embodiment, the sealing mechanism 2 further includes a sealing strip 24, with its two sides 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 structures 32 can be fixedly connected or detachably connected by bolts and screws.

[0046] By further adding a sealing strip 24 to the sealing element 23, the sealing strip can further seal the expansion gap and further enhance the sealing effect.

[0047] 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 embedded in the building 6, and the second threaded steel bar 312 is embedded in the building 6 and arranged parallel to 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.

[0048] By setting the first threaded steel bar 311 and the second threaded steel bar 312, after the first threaded steel bar 311 and the second threaded steel bar 312 are embedded in the building 6, they can be solidified into one with the building 6, realizing the connection between the embedded part 31 and the building 6. At the same time, the first threaded steel bar 311 and the second threaded steel bar 312 set in parallel can strengthen the bonding strength between the embedded part 31 and the building 6 and enhance the bonding force.

[0049] To achieve the connection between the glass curtain wall 1 and the steel structure 32, specifically, as follows: Figure 4 As shown, in one embodiment, the curtain wall node structure further includes a first connecting mechanism 4, which includes a first connecting part 41 and a second connecting part 42. The first connecting part 41 is connected to the steel structure 32, and the second connecting part 42 is connected to the first connecting part 41. An installation gap is formed between the second connecting part 42 and the first connecting part 41. The end of a glass curtain wall 1 is inserted into the installation gap and connected to the steel structure 32 via the first connecting part 41 and the second connecting part 42.

[0050] The first connecting part 41 connects to the steel structure 32, and the second connecting part 42 connects to the first connecting part 41, forming an installation gap between them to fix the glass curtain wall 1. The connection between the glass curtain wall 1 and the steel structure 32 is realized through the first connecting part 41 and the second connecting part 42.

[0051] It should be understood that the first connecting part 41 and the steel structure 32 can be connected by bolts, screws and clips, or by welding and bonding.

[0052] It should be understood that the first connecting part 41 and the second connecting part 42 are profiles, and the first connecting part 41 and the second connecting part 42 can also be formed by splicing together sheet metal.

[0053] In order to protect the contact points between the glass curtain wall 1 and the first connecting portion 41 and the second connecting portion 42, in one embodiment, such as Figure 4 As shown, the second connecting part 42 and the first connecting part 41 in the installation gap are provided with first mounting grooves on opposite sides. The first connecting mechanism 4 also includes two first protective pads 43. The two first protective pads 43 are respectively locked in the two mounting grooves, and one first protective pad 43 is provided between the first connecting part 41 and the glass curtain wall 1, and the other first protective pad 43 is provided between the second connecting part 42 and the glass curtain wall 1.

[0054] Two first protective pads 43 are disposed on both sides of the glass curtain wall 1, and are disposed between the first connecting part 41 and the glass curtain wall 1, and between the second connecting part 42 and the glass curtain wall 1. The glass curtain wall 1 indirectly contacts the second connecting part 42 and the first connecting part 41 through the two first protective pads 43, which can play a role in buffering and shock absorption, and can protect the glass curtain wall 1.

[0055] It should be understood that the first protective pad 43 can be a rubber strip, silicone pad, etc.

[0056] It should be understood that the other glass curtain wall 1 can also be connected to the steel structure 32 using the first connecting mechanism 4, or it can be connected to the steel structure 32 using a different structure, specifically, such as Figure 5 As shown, in one embodiment, the curtain wall node structure further includes a second connecting mechanism 5, which is connected to the steel structure 32. A slot is formed on one side of the second connecting mechanism 5, and another glass curtain wall 1 is inserted into the slot.

[0057] The second connecting mechanism 5 can be made of profiles, steel, etc., and the second connecting mechanism 5 and the glass curtain wall 1 can be buffered by gaskets, etc.

[0058] In order to form a first gap 21a, a second gap 21b, and a third gap 21c that are sequentially connected between the first fixing member 21 and the second fixing member 22, for this purpose, as follows: Figure 6 and Figure 7 As shown, in one embodiment, the first fixing member 21 includes a first fixing plate 211, a first folding plate 212, a second folding plate 213, and a third folding plate 214 connected in sequence. The first fixing plate 211 is connected to the first connecting part 41. The first folding plate 212 and the third folding plate 214 are arranged parallel to each other. The second folding plate 213 is arranged perpendicular to both the first folding plate 212 and the third folding plate 214, and the second folding plate 213 is located on the same side as the first folding plate 212 and the third folding plate 214. The second fixing member 22 includes a second fixing plate 221, a fourth folding plate 222, a fifth folding plate 223, and a sixth folding plate 224 connected in sequence. The second fixing plate 221 is connected to the second connecting part 41. The connecting mechanism 5 and the steel structure 32 are connected. The fourth folding plate 222 is arranged parallel to the second folding plate 213. The fifth folding plate 223 is arranged between the first folding plate 212 and the third folding plate 214, and is arranged parallel to the first folding plate 212 and the third folding plate 214. The sixth folding plate 224 is arranged between the second folding plate 213 and the fourth folding plate 222, and is parallel to the second folding plate 213. A first gap 21a is formed between the first folding plate 212 and the fifth folding plate 223. A second gap 21b is formed between the second folding plate 213 and the sixth folding plate 224. A third gap 21c is formed between the third folding plate 214 and the fifth folding plate 223 and the sixth folding plate 224.

[0059] like Figure 6 and Figure 7 As shown, in one embodiment, the sealing mechanism 2 further includes a reinforcing member 25, which includes a crossbeam 251 and an angle iron 252. The crossbeam 251 connects to the steel structure 32, and the angle iron 252 connects 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, thereby enhancing the stability of the first fixing member 21.

[0060] The connection between the crossbeam 251 and the angle iron 252, and between the angle iron 252 and the second folding plate 213, can be achieved by welding or screw connection.

[0061] like Figure 6 As shown, in one embodiment, the seal 23 is an elastic sealing strip, one side of which is fixed to the second fixing member 22 and the other side elastically abuts against the first fixing member 21.

[0062] By incorporating an elastic sealing strip, the strip possesses elasticity, providing a spring-like force to elastically conform to the first fixing member 21. It should be understood that the elastic sealing strip can be made of materials such as rubber, silicone, and latex.

[0063] Materials such as rubber, silicone, and latex will age and lose elasticity after a certain period of use, leading to seal failure. Therefore, such as Figure 7 , Figure 8 and Figure 9 As shown, in one embodiment, the seal 23 includes a fixing part 231, a rotating part 232, a sealing part 233, and an elastic part 234. The fixing part 231 is connected to the second fixing part 22, the rotating part 232 is rotatably connected to the fixing part 231, one side of the sealing part 233 is connected to the rotating part 232, and the other side abuts against the first fixing part 21. The elastic part 234 connects the fixing part 231 and the rotating part 232, and is used to provide the sealing part 233 with elastic force to fit the first fixing part 21.

[0064] One side of the sealing part 233 is rotatably connected to the rotating part 232, and the elastic part 234 can provide elastic force, so that the sealing part 233 elastically fits the first fixing member 21, thereby achieving the sealing of the second gap 21b. In this embodiment, the sealing is achieved by the fixing part 231, the rotating part 232, the sealing part 233 and the elastic part 234. The sealing process does not rely on the elastic force of the rubber, thus avoiding the aging and failure of the sealing member 23.

[0065] In order to achieve a rotatable connection between the fixed part 231 and the rotating part 232, and to seal the connection between the fixed part 231 and the rotating part 232, for this purpose, such as Figure 7 , Figure 8 and Figure 9 In one embodiment shown, the fixing part 231 has a protrusion 235 on the side facing the first fixing member 21. The protrusion 235 is cylindrical. The rotating part 232 has a groove relative to the protrusion 235 and is rotatably sleeved on the protrusion 235 through the groove.

[0066] In this embodiment, the rotating part 232 is fitted onto the protrusion 235 through a groove, thereby realizing the rotatable connection between the rotating part 232 and the protrusion 235. At the same time, the connection between the rotating part 232 and the fixed part 231 can be sealed through the cooperation between the groove and the protrusion 235.

[0067] Because the rotating part 232 is rotatably sleeved on the cylindrical protrusion 235, the rotating part 232 can slide down along the axial direction of the protrusion 235. Therefore, as Figure 7 , Figure 8 and Figure 9 In one embodiment shown, the protrusion 235 has at least one rotating groove, and the rotating part 232 has a rotating piece 236 formed relative to the rotating groove. The rotating piece 236 is inserted into the rotating groove and can rotate around the circumference of the protrusion 235.

[0068] By setting a rotating groove and a rotating plate 236, when the rotating part 232 rotates, it drives the rotating plate 236 to rotate relative to the protrusion 235, and the rotating plate 236 rotates relative to the rotating groove. The rotating plate 236 is inserted into the rotating groove, which can restrict the rotating part 232 from moving axially along the protrusion 235, thus achieving axial positioning of the rotating part 232. At the same time, since the rotating plate 236 and the rotating groove are located between the rotating part 232 and the protrusion 235, it can prevent the rotating plate 236 and the rotating groove from contacting external impurities and affecting the rotational damping of the rotating part 232.

[0069] To prevent the rotating part 232 from disengaging 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 seal 23 also includes a pin 237, which is inserted into the countersunk hole and the through hole.

[0070] The pin 237 passes through the through hole and passes through the rotating piece 236. The pin 237 can limit the rotating piece 236 in the rotating groove and prevent the rotating piece 236 and the rotating part 232 from disengaging from the protrusion 235.

[0071] It should be understood that the elastic part 234 can be a spring, an elastic strip, or an elastic block, etc. Specifically, such as... Figure 7 , Figure 8 and Figure 9 As shown, in one embodiment, the countersunk hole includes a connected fixed hole and a threaded hole. The inner diameter of the threaded hole is larger than the inner wall of the fixed hole. The pin 237 is rotatably inserted into the fixed hole. The cross-section of the pin 237 is square. The through hole is a square hole and fits onto 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 fixed hole. The sealing plug 239 is threadedly connected to the retaining ring 238. The elastic part 234 is a torsion spring. The torsion spring is built into the threaded hole, and one end 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 part 232 via the retaining ring 238, the pin 237 and the rotating plate 236. The other end of the torsion spring is connected to the fixed part 231 via the sealing plug 239.

[0072] During installation, the rotating plate 236 is first inserted into the rotating groove, and the rotating part 232 is fitted onto the protrusion 235. Then, the pin 237 is inserted into the fixing hole, and the pin 237 passes through the through hole and through the rotating plate 236. Then, the sealing plug 239 is threaded into the threaded hole. During the threaded connection, the sealing plug 239 will twist the torsion spring, so that the torsion spring generates an elastic restoring force. The elastic restoring force of the torsion spring can drive the retaining ring 238 and the pin 237 to rotate. The rotating pin 237 can apply elastic force to the rotating plate 236 and the rotating part 232, thus applying an 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, this elastic force can be maintained. In addition, 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 them, so that the elastic part 234 can provide elastic restoring force for a long time.

[0073] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
