Description

Technical Field

[0001] The present invention relates to the technical field of curtain walls, and in particular to a curtain wall unit and a curtain wall. Background Art

[0002] The curtain wall is the outer wall of the building, which is non-load-bearing and is hung up like a curtain, so it is also called a "curtain wall". It is a lightweight wall with decorative effects commonly used in modern large and high-rise buildings. It is composed of panels and supporting structural systems, and can have a certain displacement ability relative to the main structure or a certain deformation ability itself, and is an external protective structure or decorative structure of the building that does not bear the effects of the main structure. The most common is the glass curtain wall. In summer, when the sun shines on the surface of the glass curtain wall, it will cause the glass curtain wall to heat up. The glass panel is generally fixed and embedded in the aluminum alloy profile. The glass panel is sealed around the edges with sealant. Due to the obstruction of the aluminum alloy profile, the edge of the glass panel is not exposed to the sun, so that the edge and middle of the glass are heated unevenly. The middle of the glass has a higher temperature and expands, which produces tensile stress on the glass. When there are tiny cracks on the edge of the glass, these defects are easily affected by thermal stress. As the temperature difference increases, the cracks gradually increase, causing the glass to break and fall. Summary of the invention

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Example 1: Reference Figure 1-5 A curtain wall unit includes a supporting frame 1, a fixing frame 13 is fixedly connected to the supporting frame 1 by bolts, a limiting frame 14 is fixedly connected to the fixing frame 13, a glass panel 2 is abutted on the limiting frame 14, the glass panel 2 is connected to the supporting frame 1 and the limiting frame 14 by sealant, and the limiting frame 14 limits one side of the glass panel 2.

[0029] Limiting grooves 10 are provided on both ends of the vertical inner wall of the support frame 1, and the limiting grooves 10 limit the second abutting plate 9 so that the second abutting plate 9 can limit the glass panel 2. The second abutting plates 9 can be slidably arranged in the two parallel limiting grooves 10, and the second abutting blocks 9 abut against the glass panel 2. Both ends of the two second abutting plates 9 are fixedly connected with L-shaped connecting blocks 7, and the four L-shaped connecting blocks 7 can be rotatably connected with hinge rods 4. The first abutting plate 6 and the second abutting plate 9 limit the other side of the glass panel 2, so that the glass panel 2 is fixed, and as the temperature rises, the air in the connecting cylinder 11 will expand, which will drive the piston 8 to move, so that the second abutting plate 9 is driven to move, thereby changing the inclination angle of the hinge rod 4, pushing the first abutting plate 6, so that the position of the first abutting plate 6 is changed, and the first abutting plate 6 and the second abutting plate 9 are moved by the temperature increase, so that the edge of the glass panel 2 is exposed to be irradiated by sunlight, thereby ensuring that the glass panel 2 is heated evenly, thereby preventing the glass panel 2 from being damaged due to uneven heating.

[0030] The four hinged rods 4 are rotatably connected to the connecting shafts 5 through bearings, and the first abutment plates 6 are fixedly connected to the two connecting shafts 5 on the same vertical line. The two first abutment plates 6 abut against the glass panel 2, and the two first abutment plates 6 are positioned by a positioning mechanism. The positioning mechanism includes a first positioning rod 3, and the first positioning rod 3 is fixedly connected to the first abutment plate 6. A positioning hole is provided on the support frame 1, and the first positioning rod 3 can be inserted into the positioning hole. When the first abutment plate 6 moves, the position of the first positioning rod 3 in the positioning hole will be adjusted, which plays a role in limiting the first abutment plate 6 and ensures the verticality of the first abutment plate 6 so that the hinged rod 4 can drive it.

[0031] The support frame 1 is fixedly connected with a connecting tube 11, which is made of a heat-conducting material. Specifically, the heat-conducting material can be made of copper material to facilitate heat transfer. The epoxy resin paint protects the connecting tube 11. A piston 8 is abutted in the connecting cylinder 11, and air is provided between the piston 8 and the connecting cylinder 11. The piston 8 is connected to the second abutment plate 9 through a connecting mechanism. The connecting mechanism includes a moving column 34, and the moving column 34 is fixedly connected to the piston 8. A retaining ring 36 is fixedly connected to the connecting cylinder 11. The moving column 34 passes through the retaining ring 36. A fixing ear 37 is fixedly connected to the moving column 34, and the fixing ear 37 is fixedly connected to the second abutment plate 9. A second spring 35 is fixedly connected between the fixing ear 37 and the retaining ring 36. By adopting the design of the second spring 35, when the temperature drops, the second abutment plate 9 is reset, thereby resetting the first abutment plate 6.

[0032] Embodiment 2: In embodiment 1, the second abutting plate 9 is supported by the limiting groove 10. Since the curtain wall is located outdoors, there is a lot of dust, which will cause the dust to enter the limiting groove 10. As the dust accumulates, the limiting groove 10 will be blocked, affecting the movement of the second abutting plate 9 in the limiting groove 10, so that the edge of the glass panel 2 cannot be exposed to sunlight. Figure 1-9 , as another preferred embodiment of the present invention, based on Example 1.

[0033] A storage groove 22 is arranged in the transverse inner wall at the upper end of the support frame 1, and a water inlet slit 12 is obliquely opened on the inner wall of the storage groove 22, and the water inlet slit 12 collects rainwater. Both ends of the bottom wall of the storage groove 22 are connected with the limit groove 10 through a conduction mechanism, so that the storage groove 22 can collect rainwater. The two limit grooves 10 on the same vertical line are connected through a diversion channel 15. A sealing plug 21 is abutted on the conduction mechanism, and a connecting prism 30 is fixedly connected to the sealing plug 21. A movable plate 17 is penetrated on the connecting prism 30, and a pressing spring 32 is fixedly connected between the movable plate 17 and the sealing plug 21. The pressing spring 32 is in a compressed state, and the movable plate 17 is limited by the limit mechanism. A connecting rod 29 is hinged on the movable plate 17, and the connecting rod 29 A floating block 28 is hinged on the top, and a second positioning rod 18 is penetrated on the floating block 28. The second positioning rod 18 is fixedly connected to the inner wall of the storage groove 22. Rainwater enters the storage groove 22. As the water level rises, the floating block 28 is driven to move upward, thereby pulling one end of the connecting rod 29 to move upward, so that the connecting rod 29 pulls the movable plate 17 to move, and the sealing plug 21 moves. The sealing plug 21 releases the conduction of the conduction mechanism, and rainwater will enter the limit groove 10 along the conduction mechanism to flush the limit groove 10. Subsequently, the flushing water will enter the guide channel 15 and also flush the limit groove 10 below, preventing dust from clogging the limit groove 10 and avoiding the second abutment plate 9 from being unable to move.

[0034] The limiting mechanism includes a moving sleeve 19, which is sleeved on the moving plate 17. The moving sleeve 19 is fixedly connected to the inner wall of the storage slot 22 via a connecting column 33. The moving sleeve 19 limits the moving plate 17 when the moving plate 17 moves.

[0035] Embodiment 3: In embodiment 2, the buoyancy of the floating block 28 is used to drive the sealing plug 21 to move. The floating block 28 moves slowly as the water level rises, resulting in a slow movement process when the sealing plug 21 is moved. When the conducting mechanism is opened a little, water will flow out slowly. Since the water inlet slit 12 also flows in slowly, the water level in the storage tank 22 will maintain a certain water level, which will cause the position of the floating block 28 to not change much, resulting in a small amount of water flowing out and no impact force. At the same time, the flushing is intermittent, and it is difficult to flush away the dust in the limit groove 10. At the same time, due to the light weight of the floating block 28, the sealing plug 21 is abutted and sealed by the restoring force of the pressing spring 32, resulting in a certain friction between the sealing plug 21 and the bottom wall of the storage tank 22, which will cause the sealing plug 21 to be unable to rely on the gravity of the floating block 28 to reset after moving, resulting in the conducting mechanism being in an open state all the time, affecting the subsequent flushing effect. Figure 1-Figure 9 , as another preferred embodiment of the present invention, based on Example 2.

[0036] The conduction mechanism includes a guide groove 27, which is connected to the storage groove 22. A retaining ring 31 is fixedly connected to the bottom wall of the storage groove 22. The retaining ring 31 is used for the sealing plug 21 to block and limit the position, so as to prevent the attraction between the fixed magnet 20 and the iron sheet 16 from causing the sealing plug 21 to be separated from the abutment against the guide groove 27. A water outlet channel 26 is provided on the support frame 1, and the two ends of the water outlet channel 26 are respectively connected to the guide groove 27 and the limit groove 10. An abutting plug 25 is provided in the water outlet channel 26. The cross-sectional area of ​​the abutting plug 25 is larger than the cross-sectional area of ​​the guide groove 27. The abutting plug 25 seals the lower end of the guide groove 27. An inclined surface is provided on the inner wall of the water outlet channel 26. A moving rod 24 is fixedly connected to the abutting plug 25. A mounting hole is provided on the inner wall of the storage groove 22. The mounting hole is provided for mounting. A sealing ring is provided in the hole, and the inner wall of the sealing ring abuts against the moving rod 24. An iron sheet 16 is fixedly connected to the moving rod 24, a fixed magnet 20 is fixedly connected to the moving plate 17, and a moving magnet 39 is fixedly connected to the iron sheet 16. The opposite surfaces of the fixed magnet 20 and the moving magnet 39 are isotropic magnetic surfaces. A first spring 23 is fixedly connected to the moving rod 24, one end of the first spring 23 is fixedly connected to the inner wall of the storage slot 22, and the other end is fixedly connected to the iron sheet 16. The iron sheet 16 is coated with anti-rust paint to play a rust-proof role. A blocking block 40 is provided on the inner wall of the storage slot 22, and the blocking block 40 abuts against the moving magnet 39. When the iron sheet 16 is aligned with the fixed magnet 20, the blocking block 40 plays a shielding role to prevent the moving magnet 39 from affecting the fixed magnet 20.

[0037] After the sealing plug 21 is opened, water enters the guide groove 27. When the water fills the guide groove 27, the gravity of the water forms a force on the abutting plug 25, causing the abutting plug 25 to move downward, driving the moving rod 24 to move downward, and the first spring 23 is compressed, causing the iron sheet 16 to move downward. The iron sheet 16 is offset from the fixed magnet 20, and the moving magnet 39 is aligned with the fixed magnet 20. The repulsive force between the fixed magnet 20 and the moving magnet 39 will push the sealing plug 21 to move, ensuring that the sealing plug 21 is fully opened, ensuring the water flow and impact The force is used to flush away the dust. After the water in the storage tank 22 flows out, the abutment plug 25 drives the iron sheet 16 to reset under the action of the restoring force of the first spring 23. The iron sheet 16 is aligned with the fixed magnet 20. The attraction between the iron sheet 16 and the fixed magnet 20 drives the sealing plug 21 to move and reseal, ensuring that when there is water in the storage tank 22, a continuous flushing is performed. The flushing time is long and the water flow rate is large, thereby ensuring the flushing effect, flushing away the dust in the limit groove 10, and facilitating the resetting and sealing of the sealing plug 21.

[0038] When the temperature rises, the connecting tube 11 transfers heat, and the air in the connecting tube 11 expands, which will drive the piston 8 to move, so that the moving column 34 moves, and drives the second abutment plate 9 to move, thereby changing the inclination angle of the hinge rod 4, pushing the first abutment plate 6, changing the position of the first abutment plate 6, and moving the first abutment plate 6 and the second abutment plate 9 by the temperature increase, so that the edge of the glass panel 2 is exposed to the sun, ensuring that the glass panel 2 is heated evenly; when it rains, rainwater enters the storage tank 22 from the water inlet slit 12, and as the water level rises, it drives the floating block 28 to move upward, so that the floating block 28 pulls one end of the connecting rod 29 to move upward, so that the connecting rod 29 is connected to the storage tank 22. The rod 29 pulls the movable plate 17 to move, which will cause the sealing plug 21 to release the seal on the guide groove 27. When the water fills the guide groove 27, the gravity of the water forms a force on the abutment plug 25, causing the abutment plug 25 to move downward, driving the movable rod 24 to move downward, and the first spring 23 is compressed, causing the iron sheet 16 to move downward. The iron sheet 16 is offset from the fixed magnet 20, so that the movable magnet 39 is aligned with the fixed magnet 20. The repulsive force between the fixed magnet 20 and the movable magnet 39 will push the sealing plug 21 to move. The sealing plug 21 is fully opened, and water flows out from the water outlet channel 26 to flush the limit groove 10. Then the flushing water will enter the guide channel 15 and also flush the limit groove 10 below, preventing dust from clogging the limit groove 10.

[0039] Example 4: Reference Fig.10The present invention also provides a curtain wall, including a plurality of curtain wall units, the plurality of curtain wall units are sealed by sealing strips and sealants, the plurality of curtain wall units are fixedly connected to a column 38 by bolts, and the lower end of the column 38 is fixedly connected to the ground.
