Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly to an adjustable flatness curtain wall installation node. Background Art

[0002] A curtain wall is an exterior wall enclosure of a building, which does not bear weight and is hung like a curtain, so it is also called a "curtain wall". Due to its overall beauty, convenient installation, and no impact on the indoor lighting effect, the curtain wall has become a commonly used lightweight wall with decorative effects in modern large-scale buildings and high-rise buildings.

[0003] When the existing curtain wall is in use, during installation, the frame is installed first, and then the curtain wall is fixed to the frame. Therefore, during the installation process, it is very easy to be affected by the installation position of the frame, resulting in the entire curtain wall being inclined and uneven. And some slight inclinations cannot be detected by the naked eye. Therefore, the entire curtain wall does not have the function of flatness adjustment. Summary of the Invention

Specific embodiments

[0038] The following further describes the specific embodiments of the present invention with reference to the drawings. It should be noted here that the description of these embodiments is for helping to understand the present invention, but does not constitute a limitation to the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] Please refer to Figures 1 to 11As shown, the embodiment of the present invention provides an adjustable flatness curtain wall installation node, including two groups of columns 1, a plurality of curtain wall panels 4, a plurality of leveling components and a cleaning plate 36, wherein a plurality of cross bars 2 are fixedly installed between the two groups of columns 1 along the vertical direction; a plurality of curtain wall panels 4 are arranged between the two groups of columns 1 end to end in a vertical direction and are located on the outside of the two groups of columns 1, a plurality of cross bars 2 and a plurality of curtain wall panels 4 are arranged in a one-to-one correspondence at the splicing positions, the cross bars 2 and the curtain wall panels 4 are arranged at intervals inside and outside, and the outer side of each cross bar 2 Each of the plurality of leveling assemblies is fixedly installed with a mounting frame 3 for splicing two adjacent curtain wall panels 4 end to end in the vertical direction; a plurality of leveling assemblies are arranged one-to-one correspondingly to the plurality of curtain wall panels 4, and each leveling assembly includes a fixing frame 5 fixedly installed on the cross bar 2 and a plurality of rotating rods 9 which are adjustable in angle and extended toward the curtain wall panel 4 on the fixing frame 5; a first driving mechanism for adjusting the angles of the plurality of rotating rods 9 is installed on the fixing frame 5 so that the extending ends toward the curtain wall panel 4 abut against the curtain wall panel to level the curtain wall panel 4.

[0040] See also Figures 1 to 7 as well as Figure 11 As shown, the first driving mechanism includes a bidirectional screw 6 that rotatably passes through the fixing frame 5 in the vertical direction, two first screws 8 vertically arranged on opposite sides of the bidirectional screw 6, and a first bevel gear set 7 that is transmission-connected between the bidirectional screw 6 and the two first screws 8 and is used to synchronously transmit the rotation of the bidirectional screw 6 to the two first screws 8. In this embodiment, the fixing frame 5 is a cross-shaped bracket, and the two threaded sections of the bidirectional screw 6 have opposite threads. The first screw sleeves 37 are threadedly sleeved on the forward and reverse threaded sections of the bidirectional screw 6 and the two first screws 8. The ends of the plurality of rotating rods 9 that are facing away from the curtain wall panel 4 are rotationally connected to the corresponding first screw sleeves 37 through a rotating shaft. Preferably, the first bevel gear set 7 includes a first bevel gear 71 sleeved and installed on the outside of the bidirectional screw 6, and two second bevel gears 72 symmetrically arranged on both sides of the first bevel gear 71 and coaxially connected to the two first screws 8, respectively, and the two second bevel gears 72 are meshed and connected with the first bevel gear 71.

[0041] Furthermore, in this embodiment, the outer side of the rotating rod 9 is sleeved with a first connecting frame 10, a through slot is provided in the middle of the rotating rod 9, and a first connecting block 11 penetrating the through slot is connected to the first connecting frame 10.

[0042] When it is necessary to adjust the flatness of the curtain wall panel 4, rotate the bidirectional screw 6 penetrating through the fixing frame 5. When the bidirectional screw 6 rotates, it drives the first screws 8 on both sides to rotate through the first bevel gear set 7, and then drives the first screw sleeves 37 to slide. Since the thread directions of the two groups of first screws 8 are the same, and the thread directions on both sides of the bidirectional screw 6 are opposite, when the bidirectional screw 6 and the first screws 8 rotate, the four groups of first screw sleeves 37 will move towards the four directions (i.e., the four surrounding sides corresponding to each curtain wall panel 4). On one side of the first screw sleeve 37, there is a rotating rod 9 connected by a rotating shaft. In the middle of the rotating rod 9, there is a first connecting block 11 connected through a through groove, and the first connecting block 11 is installed in the groove of the first connecting frame 10. One end of the rotating rod 9 will rotate under the sliding action of the first screw sleeve 37. At the same time, affected by the first connecting block 11 penetrating through the middle, the first connecting block 11 will slide in the through groove of the rotating rod 9. Therefore, when the rotating rod 9 rotates, the other end will exert pressure on the curtain wall panel 4. Since the four groups of first screw sleeves 37 rotate synchronously, the rotation amplitudes of the rotating rods 9 are the same. When the rotating rod 9 is rotated to a state perpendicular to the fixing frame 5, when the curtain wall panel 4 is tilted, under the push of the four groups of rotating rods 9, the entire curtain wall panel 4 can be made flatter, so that the curtain wall panel 4 will not be tilted.

[0043] Please refer to Figures 1 to 4 As shown, at the top of the mounting frame 3, there is a first groove for the bottom of the upper curtain wall panel 4 to be inserted and connected. At the bottom of the mounting frame 3, there is a second groove. The bottom of the mounting frame 3 is movably embedded with a special-shaped block 12. The special-shaped block 12 can cooperate with the bottom of the mounting frame 3 to form a second groove for the top of the lower curtain wall panel 4 to be inserted and connected. The width of at least one of the first groove and the second groove is greater than the thickness of the curtain wall panel 4. Preferably, in this embodiment, at the bottom of the mounting frame 3, there is a special-shaped groove for the special-shaped block 12 to be movably embedded. There is a gap reserved between the special-shaped block 12 and the special-shaped groove and extending to the outside of the mounting frame 3. A through hole 41 is vertically formed on the special-shaped block 12, and a wedge-shaped block 13 is slidably inserted through the through hole 41. On the mounting frame 3, there is a first bayonet 39 communicated with the through hole 41 and for the bottom of the wedge-shaped block 13 to be inserted. It should be noted that the installation node further includes an installation block 15 that can be slidably inserted into the gap from the outside of the mounting frame 3. By inserting the installation block 15 into the gap, the wedge-shaped block 13 is driven to slide downward until the bottom is inserted into the first bayonet 39. And in this embodiment, the front end of the installation block 15 and one end of the wedge-shaped block 13 close to the installation block 15 are both bevel structures. A movable spring 14 is sleeved outside the wedge-shaped block 13. One end of the movable spring 14 is fixed to the wedge-shaped block 13, and the other end is fixed to the hole wall of the through hole 41. Through the elastic compression of the movable spring 14, the sliding of the wedge-shaped block 13 in the through hole 41 is realized. In the reset state of the movable spring 14, the bottom of the wedge-shaped block 13 disengages from the first bayonet 39, and the top extends out of the through hole 41 and is inserted into the gap.

[0044] Further, mounting grooves 38 communicating with the gap are symmetrically formed in the mounting bracket 3 and the special-shaped block 12 in the vertical direction. Retractable blocks 16 are respectively connected to the two mounting grooves 38. Two second bayonets 40 are formed in the mounting block 15 at positions corresponding to the two mounting grooves 38. By inserting the mounting block 15 into the gap, the two blocks 16 are driven to contract. When the mounting block 15 is inserted until the two second bayonets 40 are respectively aligned with the two blocks 16, the two blocks 16 reset and extend to engage with the corresponding second bayonets 40. It should be noted that in this embodiment, the ends of the two blocks 16 on the sides away from each other are respectively connected with a telescopic spring 17. Through the elastic compression of the telescopic spring 17, the telescopic movement of the two blocks 16 in the corresponding mounting grooves 38 is realized. The ends of the two blocks 16 close to the mounting block 15 are both bevel structures.

[0045] Furthermore, a convex block 18 is fixedly installed on the outer side of each block 16. The end of the mounting block 15 on the side relatively far from the insertion end extends out of the gap and is vertically fixedly connected with a clamping plate 152. Jacks 42 communicating with the corresponding mounting grooves are respectively formed in the clamping plate 152 at positions corresponding to the two mounting grooves 38. An unlocking pressing block 19 for driving the two blocks 16 to contract to unlock the two blocks 16 from the corresponding second bayonets 40 is slidably inserted into the jacks 42. A bevel surface group for converting the lateral movement of the unlocking pressing block 19 into the vertical movement of the convex block 18 and then driving the corresponding block 16 to contract is formed between the unlocking pressing block 19 and the convex block 18. Preferably, in this embodiment, a connecting rod 20 is fixedly connected to the side of the unlocking pressing block 19 facing away from the convex block 18. The ends of the two connecting rods 20 on the side facing away from the convex block 18 penetrate through the mounting block 15, and a second connecting block 21 is fixedly connected between the two. Preferably, first sealing blocks 22 are provided between the mounting block 15 and the mounting bracket 3, and between the mounting block 15 and the special-shaped block 12. The bottom of the special-shaped block 12 has an extension portion 121 extending to the lower curtain wall panel 4. Second sealing blocks 23 are provided between the extension portion 121 and the lower curtain wall panel 4, and between the mounting bracket 3 and the upper curtain wall panel 4. Two ejector rods 151 are connected to both sides of the clamping plate 152 for penetrating through the special-shaped block 12 and abutting against the second sealing block 23 on one side of the lower curtain wall panel 4, and for penetrating through the mounting bracket 3 and abutting against the second sealing block 23 on one side of the upper curtain wall panel 4.

[0046] When it is necessary to fix the curtain wall panel 4, the bottom of the curtain wall panel 4 can be inserted into the first groove at the top of the mounting frame 3. Then, the upper set of special-shaped blocks 12 are docked into the special-shaped grooves at the bottom of the upper set of mounting frames 3. Subsequently, the top of the curtain wall panel 4 is docked into the second groove at the bottom of the upper set of special-shaped blocks. Then, the mounting block 15 is inserted into the gap between the special-shaped block 12 and the mounting frame 3. When inserting the mounting block, since the front end of the mounting block 15 and one end of the wedge-shaped block 13 close to the mounting block 15 are both inclined surface structures, when the mounting block 15 is inserted, it will exert pressure on the wedge-shaped block 13. The wedge-shaped block 13 will shrink into the through hole 41 in the special-shaped block 12 under the pressure, and at the same time, it will exert pressure on the movable spring 14 in the through hole 41, so that the wedge-shaped block 13 passes through the special-shaped block 12 and is clamped with the first bayonet on the mounting frame 3. At this time, the special-shaped block 12 can be fixed to the bottom of the upper set of mounting frames 3 through the wedge-shaped block 13.

[0047] Meanwhile, when inserting the mounting block 16, the inclined surface at the front end of the mounting block 15 exerts pressure on the clamping block 16, so that the clamping blocks 16 on both sides of the mounting block 15 are respectively contracted into the mounting grooves on the special-shaped block 12 and the mounting frame 3, and exert pressure on the telescopic spring 17 in the mounting groove. When the mounting block 15 is inserted until the two second bayonets 40 are respectively aligned with the two pressing blocks 16, at this time, the telescopic spring 17 will drive the clamping block 16 to reset, and make the clamping block 16 clamped into the corresponding second bayonet 40, thereby fixing the mounting block 15, the special-shaped block 12 and the mounting frame 3 to each other, making the special-shaped block 12 not easy to loosen. Preferably, when pushing the mounting block 15, the mounting block 15 will exert pressure on the mounting frame 3 and the first sealing block 22 between the special-shaped block 12 and the mounting block 15. Since the first sealing block 22 is made of rubber, after being pressed by the mounting block 15, it deforms, so as to seal the gaps between the mounting block 15 and the mounting frame 3, and between the mounting block 15 and the special-shaped block 12, preventing rainwater from entering the interior of the curtain wall panel 4 along the mounting frame 3 and the special-shaped block 12. And in this embodiment, the ejector rods 151 penetrating the mounting frame 3 and the special-shaped block 12 are respectively provided on the clamping plates 152 of the mounting block 15. When pushing the mounting block 15, the ejector rods 151 respectively press the second sealing blocks 23 between the extending part 121 and the curtain wall panel 4 on the lower side and between the mounting frame 3 and the curtain wall panel 4 on the upper side. Since the second sealing blocks 23 are also made of rubber, they deform after being pressed, so as to seal the connection between the curtain wall panel 4 and the mounting frame 3 and the special-shaped block 12, making the waterproof effect of the entire curtain wall panel 4 better.

[0048] When it is necessary to disassemble the curtain wall panel 4, only need to push the second connecting block 21 on one side of the mounting block 15 towards the mounting block 15, so that the second connecting block 21 pushes the connecting rod 20 penetrating through the mounting block 15 to move. One end of the connecting rod 20 is connected to the unlocking pressing block 19. One side of the unlocking pressing block 19 and one side of the convex block 18 are both inclined surface structures. Therefore, when the pressing block 19 moves, it will generate extrusion on the convex block 18 through the inclined surface. Since the convex block 18 is installed on one side of the clamping block 16, under the action of the convex block 18, the clamping blocks 16 on both sides of the mounting block 15 will respectively contract into the mounting grooves of the mounting frame 3 and the special-shaped block 12, so that the mounting block 15 is not limited by the clamping block 16. Then the mounting block 15 can be disassembled from the gap between the mounting frame 3 and the special-shaped block 12. At the same time, since the wedge-shaped block 13 is not extruded by the mounting block 15, it will be reset through the movable spring 14. Without the wedge-shaped block 13 limiting the special-shaped block 12, the special-shaped block 12 can be disassembled from the bottom of the mounting frame 3, thus facilitating the quick disassembly of the curtain wall panel 4.

[0049] It should be noted that during use, the two groups of columns 1 can be limited and fixed on the exterior wall of the building by bolts, and then the cross bar 2 can be fixed between the two groups of columns 1 by bolts. Finally, the mounting frame 3 can be welded to one side of the cross bar 2 by welding. At this time, the curtain wall panel 4 can be placed on the mounting frame 3. The special-shaped block 12 is docked to the top of the curtain wall panel 4, and the special-shaped block 12 and the upper group of mounting frames 3 are fixed and limited through the mounting block 15, thus completing the installation of the curtain wall panel 4.

[0050] Please refer to Figure 6 and Figure 8As shown, in this embodiment, a cleaning plate 36 is also provided on the outside of the plurality of curtain wall panels 4 and slidably installed between the two groups of columns 1 in the vertical direction, and a second driving mechanism for driving the cleaning plate 36 to slide in the vertical direction is installed on at least one column 1, so as to clean the curtain wall panels 4. Preferably, the second driving mechanism includes a first screw rod 27 rotatably and vertically penetrating the column 1 and a second screw sleeve 28 threadedly mounted on the first screw rod 27, a cleaning frame 29 is fixedly connected to one side of the second screw sleeve 28, and the cleaning plate 36 is mounted on the cleaning frame 29. In this embodiment, a transmission shaft 25 is rotatably mounted on the column 1, and the transmission shaft 25 is arranged to penetrate the column 1 in the horizontal direction. One end of the transmission shaft 25 passes through the column 1 and is fixedly connected to the drive motor 24 (the output end of the drive motor 24 is connected to the transmission shaft 25 through a coupling), and the other end is vertically provided with a first screw rod 27. A second bevel gear set 26 for synchronously transmitting the rotational motion of the transmission shaft 25 to the first screw rod 27 is transmission-connected between the first screw rod 27 and the transmission shaft 25. The second bevel gear set 26 includes a third bevel gear 261 coaxially connected to the end of the transmission shaft 25 on the side facing away from the drive motor 24, and a fourth bevel gear 262 arranged perpendicular to the third bevel gear 261 and meshingly connected to the third bevel gear 261. The first screw rod 27 penetrates and is connected to the fourth bevel gear 262.

[0051] When the curtain wall panel 4 needs to be cleaned, the drive motor 24 can be started. The drive motor 24 will drive the transmission shaft 25 to rotate through the coupling. When the transmission shaft 25 rotates, the first screw rod 27 is driven to rotate through the second bevel gear set 26, thereby driving the second screw sleeve 28 on the outer side of the first screw rod 27 to slide along the length direction of the first screw rod 27. Because a cleaning frame 29 is connected to one side of the second screw sleeve 28, the other end of the cleaning frame 29 is slidably connected to the slide groove of another group of vertical rods 1 through a slider. Under the guidance of the cleaning frame 29, the first screw rod 27 will drive the second screw sleeve 28 to slide along the direction of the first screw rod 27 when rotating, and the curtain wall panel 4 can be cleaned through the cleaning plate 36 on one side of the cleaning frame 29.

[0052] See also Figures 6 to 8As shown, in order to achieve a better cleaning effect for the curtain wall panel 4, in this embodiment, a water tank 30 is installed in the middle of the cleaning rack 29.
