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 outer facade of the glass curtain wall is not simple due to the support of the insulating glass 21 by a frame structure, the present invention provides a curtain wall system, which can make the outer facade composed of the insulating glass 21 more simple.

[0021] It should be noted that the curtain wall system 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 system to the glass curtain wall is taken as an example for explanation, and the principle of applying the curtain wall system to other types of equipment is substantially the same as that applied to the glass curtain wall, and will not be described one by one here.

[0022] See also Figure 1 , Figure 1 The present invention is a structural schematic diagram of a curtain wall system in an embodiment of the present invention. A curtain wall system includes a steel frame structure 1 and a glass curtain wall 2. The steel frame structure 1 includes a column 11, a plurality of beams 12 and a fixing member 13. The plurality of beams 12 are arranged at intervals and connected to the columns 11. The fixing member 13 is connected to the column 11 and is configured to be fixed to the building 5. The glass curtain wall 2 includes a plurality of insulating glasses 21, a support member 22 and a connecting member 23. The plurality of insulating glasses 21 are arranged at intervals. One end of the support member 22 is connected to the beam 12 and the other end abuts against the bottom of the insulating glass 21. The connecting member 23 is arranged between the insulating glass 21 and the beam 12 and connects the insulating glass 21 and the beam 12.

[0023] Specifically, in the present application, the columns 11, the beams 12 and the fixing members 13 constitute a steel frame structure for fixing the glass curtain wall 2. In the glass curtain wall 2, the connecting member 23 can fix the side of the insulating glass 21, and can limit the movement of the insulating glass 21 in the direction away from the building 5. The supporting member 22 is used to support the bottom of the insulating glass 21, and can support the supporting member 22 in the vertical direction; the supporting member 22 is only arranged at the bottom of the insulating glass 21, and the connecting member 23 is arranged on the side of the insulating glass 21 close to the building 5, without protruding the structure of the insulating glass 21, so that the facade of the glass curtain wall 2 is simpler.

[0024] It should be understood that the support member 22 may be a support rod, a support block, a support bar, etc. Specifically, Figure 2 As shown, in one embodiment, the support member 22 includes a support bar 221 and a buffer bar 222 . One end of the support bar 221 is connected to the cross beam 12 , and the other end is disposed under the insulating glass 21 . The buffer bar 222 is disposed between the support bar 221 and the insulating glass 21 .

[0025] By providing the support bar 221, the support bar 221 supports the bottom of the insulating glass 21 through the buffer bar 222, and transmits the gravity of the insulating glass 21 to the building 5; by providing the buffer bar 222, the insulating glass 21 and the support bar 221 can be spaced to avoid hard contact between the insulating glass 21 and the support bar 221.

[0026] The connecting member 23 may be an adhesive or a profile that plays a connecting role, for example, Figure 2As shown, in one embodiment, the connecting member 23 is a profile for fixing the insulating glass 21, and the connecting member 23 and the insulating glass 21 are bonded by a silicone structural sealant.

[0027] In order to seal the gaps between the insulating glass 21 to prevent impurities and rainwater from penetrating between the adjacent insulating glass 21, Figure 2 As shown, in one embodiment, the glass curtain wall 2 further includes a sealing member 24 , which is disposed between adjacent insulating glasses 21 to seal the gaps between the adjacent insulating glasses 21 .

[0028] By providing the sealing member 24 , which is provided between adjacent insulating glasses 21 , the adjacent insulating glasses 21 can be sealed, and impurities can be effectively prevented from passing through between the adjacent insulating glasses 21 .

[0029] It should be understood that the sealing member 24 may be a sealant, a sealing block, etc. Specifically, Figure 2 As shown, in one embodiment, the sealing member 24 includes a foam rod 241 and an adhesive layer 242. The foam rod 241 is disposed between adjacent insulating glasses 21. The adhesive layer 242 is disposed between adjacent insulating glasses 21 and is located on the side of the foam rod 241 away from the building 5. The adhesive layer 242 connects the adjacent insulating glasses 21 and the foam rod 241.

[0030] In this embodiment, by setting the adhesive layer 242, the adhesive layer 242 can seal the gap between adjacent insulating glasses 21, and by setting the foam rod 241, the foam rod 241 can block the gap between adjacent insulating glasses 21. When the adhesive layer 242 is injected between adjacent insulating glasses 21, it can block the flow of the adhesive and prevent the adhesive from flowing deep into the gap between the two insulating glasses 21, thereby confining the adhesive in the cavity between the two insulating glasses 21 and the foam rod 241.

[0031] The building 5 will expand and contract to a certain extent due to factors such as temperature changes, uneven foundation settlement and earthquakes. In order to prevent the columns 11 from deforming and forming cracks during the expansion and contraction of the building 5, for example, Figure 3 As shown, in one embodiment, there are multiple columns 11, at least some of the columns 11 are spaced apart in the vertical direction, and expansion joints are provided between the columns 11 spaced apart in the vertical direction.

[0032] By distributing the columns 11 at intervals in the vertical direction to form expansion joints, the columns 11 can be driven to move when the building 5 is extended, so that the adjacent columns 11 in the vertical direction can be extended and contracted at the expansion joints, thereby preventing the columns 11 from breaking or deforming when the building 5 is extended and contracted due to factors such as temperature changes, uneven foundation settlement and earthquakes.

[0033] In order to fix the vertically spaced columns 11, for this purpose, Figure 1 and Figure 4 As shown, in one embodiment, there are multiple fixing members 13, and at least two fixing members 13 are respectively connected to two columns 11 spaced apart in the vertical direction.

[0034] By providing a plurality of fixing members 13 , the plurality of fixing members 13 are respectively connected to the columns 11 spaced apart in the vertical direction, so that the columns 11 spaced apart in the vertical direction can be fixed, thereby achieving a fixed connection between the columns 11 and the building 5 .

[0035] It should be understood that the fixing member 13 may be a steel structure, a beam structure, etc., specifically, Figure 4 As shown, in one embodiment, the fixing member 13 includes at least two embedded parts 131, a connecting plate 132 and a channel steel 133, at least two embedded parts 131 are configured to be embedded in the building 5, the connecting plate 132 is connected to the at least two embedded parts 131, one end of the channel steel 133 is connected to the connecting plate 132, and the other end is detachably connected to the column 11.

[0036] By providing the embedded part 131, the connection between the fixing part 13 and the building 5 is achieved. It should be understood that the embedded part 131 can be a steel bar, an anchor nail, an anchor bolt, etc.; by providing the connecting plate 132 and the channel steel 133, the connection between the embedded part and the column 11 is achieved; it should be understood that the channel steel 133 and the column 11 can be detachably connected by bolts, screws, clips, etc.

[0037] In order to prevent fire on the glass curtain wall 2, specifically, Figure 4 As shown, in one embodiment, the curtain wall system further includes a fire protection mechanism 3 , which is arranged along the length direction of the beam 12 and connects the beam 12 and the building 5 .

[0038] By arranging the fireproof structure along the length direction of the cross beam 12, the fireproof structure can prevent the fire from extending along the height direction of the building 5, thereby playing a role in fire prevention.

[0039] It should be understood that the fireproof components can be partitions and fireproof materials that play a fireproof role, such as Figure 4 As shown, in one embodiment, the fire protection mechanism 3 includes two galvanized steel plates 31 and a fire protection filling layer 32. A fire protection cavity is formed between the two galvanized steel plates 31. One ends of the two galvanized steel plates 31 are respectively connected to two adjacent and perpendicular sides of the beam 12, and the other ends of the two galvanized steel plates 31 are respectively connected to two adjacent and perpendicular sides of the building 5, and the fire protection filling layer 32 is arranged in the fire protection cavity.

[0040] By setting the galvanized steel plate 31, the galvanized steel plate 31 can fix the fireproof filling layer 32, and the galvanized steel plate 31 is also a flame-retardant material. The galvanized steel plate 31 and the fireproof filling layer 32 can seal the gap between the beam 12 and the building 5, which can play a fire prevention role.

[0041] In order to prevent the fire from extending into the fire cavity between the end of the galvanized steel plate 31 and the beam 12 and the side of the building 5, Figure 5 As shown, in one of the embodiments, a sealed cavity is formed between one end of the galvanized steel plate 31 and the side of the beam 12, and between the other end of the galvanized steel plate 31 and the side of the building 5. The size of the sealed cavity gradually increases along the direction close to the end of the galvanized steel plate 31. The fire protection mechanism 3 also includes a plurality of fire protection sealing layers 33, and the fire protection sealing layers 33 are arranged in the sealed cavity.

[0042] A sealed cavity is provided, and the size of the sealed cavity gradually increases toward the end of the galvanized steel plate 31. A fireproof sealing layer 33 is formed after the fireproof sealing material is filled into the sealed cavity. This can seal the gap between the galvanized steel plate 31 and the building 5 and the beam 12, thereby preventing the flame from extending into the fire cavity through the gap.

[0043] like Figure 3 As shown, in one of the embodiments, the expansion joints between adjacent columns 11 are filled with a weather-resistant sealant layer 14, which is sealed by the weather-resistant sealant layer 14, and in the vertical direction, the two columns 11 spaced apart are electrically connected by a copper ohmic bend interlayer jumper 15. In this embodiment, the sealing is performed by an elastically retractable weather-resistant sealant layer 14, and when the columns 11 are retracted, the weather-resistant sealant layer 14 can elastically adapt to the change in the distance between the columns 11, and the electrical connection between the spaced columns 11 is achieved by the copper ohmic bend interlayer jumper 15, so that a reliable connection between the main structure and the lightning protection device is achieved from top to bottom.

[0044] The weather-resistant sealant layer 14 has a certain service life. After a certain service life, the elasticity will fail. In addition, the weather-resistant sealant layer 14 cannot play a role in fire prevention.

[0045] For this reason, Figure 6 and Figure 7As shown, in one of the embodiments, the curtain wall system also includes a rigid sealing mechanism 4, which includes two connectors 41 and an elastic sealing member 42. The two connectors 41 are arranged between the two columns 11. The connector 41 includes a plug-in frame 411 and an end plate 412. The plug-in frame 411 is inserted into the cavity in the column 11. The end plate 412 is arranged at the end of the column 11 and connected to the plug-in frame 411. The elastic sealing member 42 is arranged between the end plates 412 of the two connectors 41, and the elastic sealing member 42 elastically abuts against the two end plates 412. The spaced columns 11 are conductively connected via the plug-in frame 411, the end plate 412 and the elastic sealing member 42.

[0046] By setting up a rigid sealing structure 4, the rigid sealing structure 4 does not use adhesive and will not fail over time. The distance between the two end plates 412 can be changed, and the elastic sealing member 42 can adapt to the change in the distance between the two end plates 412, so as to achieve sealing of the gap between the columns 11; at the same time, the end plate 412 is connected to the column 11 through the plug-in frame 411, and the elastic sealing member 42 abuts against the end plate 412. No welding structure is used between the device and the column 11, so as to meet the requirements of the new construction regulations; at the same time, between the retractable columns 11, the elastic sealing member 42, the end plate 412 and the column 11 form a stable conductive circuit, so as to achieve a reliable connection between the main structure and the lightning protection device.

[0047] like Figure 8 and Fig. 9 As shown, in one embodiment, the elastic sealing member 42 includes a fixed plate 421, a rotating portion 422, a sealing plate 423 and an elastic portion 424, the fixed plate 421 is connected to the end plate 412, the rotating portion 422 is rotatably connected to the fixed plate 421, one side of the sealing plate 423 is connected to the rotating portion 422, and the other side abuts against the other end plate 412, and the elastic portion 424 connects the fixed plate 421 and the rotating portion 422, and is used to provide elastic force for the sealing plate 423 to elastically fit the end plate 412.

[0048] One side of the sealing plate 423 is rotatably connected to the rotating part 422, and the elastic part 424 can provide elastic force, so that the sealing plate 423 elastically fits the end plate 412, thereby sealing the gap between the two end plates 412. In this embodiment, sealing is performed by the fixed plate 421, the rotating part 422, the sealing plate 423 and the elastic part 424. The sealing process does not rely on the elastic force of the rubber, thereby avoiding aging and failure of the elastic sealing component 42.

[0049] The fixing plate 421 of the elastic blocking member 42 is welded to one of the two end plates 412 or connected by bolts.

[0050] In order to realize the rotation connection between the fixed plate 421 and the rotating part 422, it is also necessary to seal the connection between the fixed plate 421 and the rotating part 422. Figure 8 and Fig. 9 As shown, in one embodiment, the fixing plate 421 is formed with a protrusion 425 outwardly, the protrusion 425 is cylindrical, and the rotating part 422 is formed with a groove relative to the protrusion 425 and can be rotatably sleeved on the protrusion 425 through the groove.

[0051] In this embodiment, the rotating part 422 is sleeved on the protrusion 425 through the groove, thereby realizing the rotational connection between the rotating part 422 and the protrusion 425. At the same time, through the cooperation between the groove and the protrusion 425, the connection between the rotating part 422 and the fixed plate 421 can be sealed.

[0052] Since the rotating portion 422 can be rotatably sleeved on the cylindrical protrusion 425, the rotating portion 422 can slide along the axial direction of the protrusion 425. Figure 8 and Fig. 9 As shown, in one embodiment, the protrusion 425 is provided with at least one rotation groove, and the rotation portion 422 is formed with a rotation piece 426 relative to the rotation groove. The rotation piece 426 is inserted into the rotation groove and can rotate along the circumferential direction of the protrusion 425 .

[0053] By providing a rotating groove and a rotating piece 426, when the rotating part 422 rotates, the rotating piece 426 is driven to rotate relative to the protrusion 425, and the rotating piece 426 rotates relative to the rotating groove; and the rotating piece 426 is inserted into the rotating groove, which can limit the axial movement of the rotating part 422 along the protrusion 425, thereby realizing the axial limitation of the rotating part 422. At the same time, since the rotating piece 426 and the rotating groove are located between the rotating part 422 and the protrusion 425, it is possible to prevent the rotating piece 426 and the rotating groove from contacting external impurities and affecting the rotation damping of the rotating part 422.

[0054] In order to prevent the rotating portion 422 from being separated from the protrusion 425, Figure 8 and Fig. 9 As shown, in one embodiment, the protrusion 425 is provided with a countersunk hole along the axial direction, and the rotating piece 426 is provided with a through hole relative to the countersunk hole; the elastic sealing member 42 also includes a latch 427, and the latch 427 is inserted into the countersunk hole and the through hole.

[0055] The latch 427 passes through the rotating piece 426 via the through hole. The latch 427 can restrict the rotating piece 426 in the rotating groove, thereby preventing the rotating piece 426 and the rotating portion 422 from being separated from the protrusion 425 .

[0056] It should be understood that the elastic portion 424 may be a spring, an elastic strip, an elastic block, etc. Specifically, Figure 8 and Fig. 9As 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 latch 427 can be rotatably inserted in the fixing hole, the cross-section of the latch 427 is square, the through hole is a square hole and is fitted on the latch 427, the elastic sealing member 42 also includes a retaining ring 428 and a sealing plug 429, the retaining ring 428 is connected to the latch 427 and is built into the threaded hole, the outer diameter of the retaining ring 428 is larger than the inner diameter of the fixing hole, the sealing plug 429 is threadedly connected to the retaining ring 428, the elastic part 424 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 428, and the other end is connected to the sealing plug 429, one end of the torsion spring is connected to the rotating part 422 via the retaining ring 428, the latch 427 and the rotating sheet 426, and the other end of the torsion spring is connected to the fixing plate 421 via the sealing plug 429.

[0057] During the installation process, the rotating piece 426 is first inserted into the rotating groove, and the rotating part 422 is sleeved on the protrusion 425, and then the pin 427 is inserted into the fixing hole, and the pin 427 passes through the rotating piece 426 through the through hole, and then the sealing plug 429 is threadedly connected to the threaded hole. During the threaded connection process, the sealing plug 429 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 428 and the pin 427 to rotate, and the rotating pin 427 can apply elastic force to the rotating piece 426 and the rotating part 422, so as to apply elastic restoring force to the rotating part 422; at the same time, due to the self-locking of the sealing plug 429 and the threaded hole, the elastic force can be maintained. At the same time, the sealing plug 429, the elastic part 424 and the pin 427 are all built into the countersunk hole, which can prevent impurities from contacting the elastic part 424 and the pin 427 and corroding the elastic part 424 and the pin 427, so that the elastic part 424 can provide elastic restoring force for a long time.

[0058] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention.
