Description

Technical Field

[0001] The present invention relates to the field of building decoration engineering, and more particularly to a curtain wall connection member and a curtain wall. Background Art

[0002] In recent years, with the rapid development of the construction industry, building designs have become increasingly diverse. Curtain walls have been favored due to their advantages such as light weight, high strength, high transparency, energy conservation and environmental protection. Curtain walls with different shapes and styles have emerged in abundance, and special types of curtain walls have become increasingly rich, such as hexagonal grid curtain walls where three sides meet at a point similar to a honeycomb and triangular grid curtain walls where six sides meet at a point. Along with this, new changes have occurred in the connection members between the curtain wall frames or unit components with such polygonal grids and the main structure. Currently, the existing curtain wall connection members are mainly used for conventional curtain wall buildings, that is, mainly for curtain wall buildings with rectangular grids, to achieve the connection between the curtain wall frame or curtain wall unit component and the building main structure, and can meet conditions such as load transfer and adaptation to different degrees of deviation. However, since the curtain wall includes not only its own dead load, but also wind load, snow load, seismic load, etc., the load values generated by the combination of these loads are usually large for the enclosure structure, and the construction deviation of the building main body is usually much higher than that of the curtain wall construction. At present, the existing curtain wall connection members cannot adapt to the complex and changeable connections and structural deviations on the building main body site. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a curtain wall connection member and a curtain wall that can adapt to the complex and changeable connections and structural deviations on the building main body site.

[0004] To solve the above technical problem, according to one aspect of the present invention, there is provided a curtain wall connection member, comprising:

[0005] A moving base, installed on the building main body, including a fixed locking portion and a moving rotating portion. A first thread is provided on the moving rotating portion, and one end thereof is located within the fixed locking portion and can move within the plane of the fixed locking portion;

[0006] A connection assembly, including a cylindrical body threadedly connected to the moving rotating portion, a plurality of connecting members extending outward from the side wall of the cylindrical body, a plurality of sleeves sleeved on the connecting members, and a plurality of pressing blocks for connecting the curtain wall unit on one side. The sleeves can move on the connecting members and can be fixed to the connecting members by first fasteners. A card slot is provided on the upper surface of the sleeves, and a plurality of second fasteners that can move within the card slot are provided in the card slot. The other side of each pressing block is installed on the sleeve through the second fasteners to adjust the position of the curtain wall unit.

[0007] A further technical solution thereof is as follows: the mobile rotating part includes a chassis and a rod extending upward from the upper end surface of the chassis, the first thread is provided on the rod, and the fixed locking part includes a cover plate and a locking disc. The cover plate is fixed to the building main body, and a cylindrical accommodating space is arranged therein. The chassis is located in the accommodating space and can move therein. The rod penetrates through the cover plate, and the locking disc is threadedly connected to the rod to fix the position of the chassis in the accommodating space.

[0008] A further technical solution thereof is as follows: a card slot is formed by recessing downward in the middle of the upper surface of the kit. Correspondingly, the connecting piece is of a hollow structure, and a groove is formed on the end surface far away from the cylinder body to be adapted to the downward recessed upper surface of the kit, so that the kit is sleeved on the connecting piece and can move on the connecting piece.

[0009] A further technical solution thereof is as follows: the kit further includes two baffles respectively arranged on both sides of the top of the card slot to prevent the second fastener from falling off the card slot.

[0010] A further technical solution thereof is as follows: the lower surface of the pressing block is an arc surface, and two long holes are arranged on the pressing block. The screw rod of the second fastener penetrates through the long holes and can move in the long holes, and the pressing block can be fixed to the kit by a nut.

[0011] A further technical solution thereof is as follows: the pressing block includes a first mounting plate and a second mounting plate formed by bending downward from one side of the first mounting plate for connecting with the curtain wall unit. The long holes are arranged on the first mounting plate, and the lower surface of the first mounting plate is an arc surface.

[0012] A further technical solution thereof is as follows: the connecting assembly further includes a plurality of gaskets. The lower ends on both sides of the gasket are serrated. A rack meshing with the lower end of the gasket is arranged on the upper surface of the pressing block. The head of the second fastener is located in the card slot, and its screw rod sequentially penetrates through the card slot, the pressing block and the gasket, and the pressing block is fixed to the kit by a nut.

[0013] A further technical solution thereof is as follows: the connecting assembly includes six connecting pieces, six kits and twelve pressing blocks. The six kits are respectively sleeved on the six connecting pieces, and a gap is reserved between the end of the kit close to the cylinder body and the end of the connecting piece extending out of the cylinder body. Each kit is connected with two pressing blocks through a second fastener, and each curtain wall unit is arranged between two adjacent kits to be fixed to the connecting assembly through the pressing block.

[0014] To solve the above technical problems, according to another aspect of the present invention, a curtain wall is provided, including a plurality of curtain wall units and a plurality of the above-mentioned curtain wall connecting members. Each curtain wall unit is installed between two adjacent kits through a pressing block.

[0015] Compared with the prior art, the moving and rotating part of the curtain wall connecting member of the present invention is located within the fixed locking part and can move within the plane of the fixed locking part. Thus, the moving and rotating part can be freely adjusted within a certain plane direction range. The cylindrical body in the connecting component for connecting with the curtain wall unit is threadedly connected to the moving and rotating part. At the same time, the angle and height of the curtain wall unit can be adjusted. One side of the pressing block in the connecting component is connected to the curtain wall unit, and the other side is installed on the kit through the second fastener. The head of the second fastener is arranged in the card slot of the kit and can move within the card slot. Thus, the position of the pressing block can be adjusted, and further the position of the curtain wall unit can be adjusted. Since the kit is sleeved on the connecting piece and can move on the connecting piece to adapt to the installation deviation and the slight processing deviation of the curtain wall unit, it can be seen that the curtain wall connecting member of the present invention can adapt to the complex and changeable connections and structural deviations on the construction site of the building main body through the cooperation of the moving and rotating part, the fixed locking part and the connecting component.

[0021] To enable those of ordinary skill in the art to more clearly understand the purpose, technical solution and advantages of the present invention, the following further elaborates on the present invention in conjunction with the drawings and embodiments.

[0022] Refer to Figures 1 to 3 , Figures 1 to 3Shows a specific embodiment of the curtain wall connection member 10 of the present invention. In the embodiment shown in the drawings, the curtain wall connection member 10 includes a moving base 11 and a connection assembly. Among them, the moving base 11 is installed on the building main body 3 (such as building steel structure or concrete structure embedment), and includes a fixed locking portion 111 and a moving and rotating portion 112. A first thread 1123 is provided on the moving and rotating portion 112, and one end thereof is located within the fixed locking portion 111 and can move within the plane of the fixed locking portion 111; the connection assembly includes a cylindrical body 121 threadedly connected to the moving and rotating portion 112, a plurality of connecting members 122 extending outward from the side wall of the cylindrical body 121, a plurality of sets 123 sleeved on the connecting members 122, and a plurality of pressing blocks 124 for connecting the curtain wall unit 20 on one side. The set 123 can move on the connecting member 122 and can be fixed to the connecting member 122 by a first fastener 125. A card slot 1231 is provided on the upper surface of the set 123, and a plurality of second fasteners 127 that can move within the card slot 1231 are provided within the card slot 1231. The other side of each pressing block 124 is installed on the set 123 through the second fastener 127 to adjust the position of the curtain wall unit 20 through the second fastener 127. In this embodiment, since rotating the connection assembly will cause a certain change in its height on the moving and rotating portion 112, but due to the small pitch of the thread, within a rotation angle of ±30°, the change in the positioning height of the connection assembly is less than 1 mm. Therefore, when the rotation angle is less than 30°, the change in the height of the connection assembly can be ignored.

[0023] Preferably, in this embodiment, in order to install the triangular grid curtain wall unit 20, six connecting members 122, six sets 123, and twelve pressing blocks 124 are provided. The six sets 123 are respectively sleeved and fixed on the six connecting members 122, and a gap is reserved between the end of the set 123 close to the cylindrical body 121 and the end of the connecting member 122 extending from the cylindrical body 121 to adapt to the slight installation deviation of the moving and rotating portion 112 and the subsequent slight processing deviation of the curtain wall unit 20. Two pressing blocks 124 are connected to each set 123 through the second fastener 127, and each curtain wall unit 20 is arranged between two adjacent sets 123 and fixed to the connection assembly through the pressing block 124.

[0024] Based on the above design, during installation, the moving and rotating part 112 can move within the plane of the fixed locking part 111 to freely adjust the position of the curtain wall unit 20 within a certain range of planar directions. Since the cylindrical body 121 is threadedly connected to the moving and rotating part 112, the angle and height of the curtain wall unit 20 can be adjusted. One side of the pressing block 124 in the connecting component is connected to the curtain wall unit 20, and the other side is installed on the kit 123 through the second fastener 127. The head of the second fastener 127 is arranged in the card slot 1231 of the kit 123 and can move within the card slot 1231, so that the position of the pressing block 124 can be adjusted, thereby further adjusting the position of the curtain wall unit 20. Since the kit 123 is sleeved on the connecting piece 122 and can move on the connecting piece 122 to adapt to the installation deviation and slight processing deviation of the curtain wall unit 20, it can be seen that the curtain wall connecting member 10 of the present invention is convenient for on-site installation, has a multi-directional adjustment function, can adapt to the complex and changeable connections of the building main body 3 on site, meet the deformation requirements of the curtain wall system, and at the same time can adapt to the complex and changeable structural deviation conditions of the building main body 3.

[0025] In some embodiments, the moving and rotating part 112 includes a chassis 1121 and a rod 1122 extending upward from the upper end surface of the chassis 1121. The first thread 1123 is provided on the rod 1122, and the fixed locking part 111 includes a cover plate 1111 and a locking disc 1112. Figure 3 In order to clearly show the specific connection relationship between the cover plate 1111 and the chassis 1121, the cover plate 1111 and the locking disc 1112 are sectioned. The cover plate 1111 is fixed to the building main body 3, and a cylindrical accommodating space 1113 is provided therein. The chassis 1121 is located in the accommodating space 1113 and can move within the accommodating space 1113. The rod 1122 passes through the cover plate 1111, and the locking disc 1112 is threadedly connected to the rod 1122 to fix the position of the chassis 1121 within the accommodating space 1113. Based on the above design, the chassis 1121 can be freely adjusted in all directions within a certain range in the plane of the cylindrical accommodating space 1113. After the adjustment is completed, torque is applied to the locking disc 1112 until the positions of the chassis 1121 and the cover plate 1111 are locked. At this time, the locking disc 1112 and the cover plate 1111 are welded and fixed, and thus the installation of the moving base 11 is completed.

[0026] Continue to refer to Figure 1 and Figure 2 to more clearly show the structure of the connecting piece 122. Figure 1The sleeve 123 is removed from the three connecting members 122 in the embodiment. Specifically, further, in the present embodiment, the middle portion of the upper surface of the sleeve 123 is recessed downward to form the slot 1231. Accordingly, the connecting member 122 is a hollow structure, and a groove 1221 is provided on one end surface away from the cylindrical body 121 to match the recessed upper surface of the sleeve 123, so that the sleeve 123 is sleeved on the connecting member 122 and can move on the connecting member 122. Preferably, the sleeve 123 also includes two baffles 1232 respectively disposed on both sides of the top of the slot 1231 to prevent the second fastener 127 from falling off from the slot 1231. Based on the above design, the head of the second fastener 127 is inserted into the slot 1231 from both ends of the sleeve 123 and can move in the slot 1231. Based on the design of the baffles 1232 on both sides, the head of the second fastener 127 can be prevented from falling off from the upper surface of the slot 1231.

[0027] In some embodiments, the connecting assembly also includes a plurality of gaskets 126, the lower ends of both sides of the gaskets 126 are serrated, the pressing block 124 includes a first mounting plate 1242 and a second mounting plate 1243 bent downward from one side of the first mounting plate 1242 for connecting to the curtain wall unit 20, the upper surface of the first mounting plate 1242 is provided with a rack 1244 meshing with the lower end of the gasket 126, and the lower surface of the first mounting plate 1242 is an arc-shaped surface, the first mounting plate 1242 is provided with two long holes 1241, the head of the second fastener 127 is located in the slot 1231, and its screw rod passes through the slot 1231, the long hole 1241 of the pressing block 124 and the gasket 126 in sequence, and the screw rod can move in the long hole 1241, and the pressing block 124 is fixed to the kit 123 by a nut. Based on the above design, during installation, the second mounting plate 1243 can be fixedly mounted on the curtain wall unit 20, and through the cooperation of the rack 1244 on the upper surface of the first mounting plate 1242 in the pressing block 124, the serrated lower end of the gasket 126 and the second fastener 127, the combination of the curtain wall unit 20 and the pressing block 124 can be locked on the kit 123. Since the lower surface of the pressing block 124 is an arc-shaped surface, it can adapt to changes in a certain angle, and can also adapt to the situation where the angle between adjacent curtain wall units 20 is not 180°. At the same time, since the curtain wall unit 20 and the pressing block 124 are fixed on the slot 1231 of the kit 123 through the second fastener 127 and the gasket 126, the load can be transmitted to the kit 123, the connecting member 122 and the cylindrical body 121 in the connecting assembly through the pressing block 124 in a three-point support force mode, and can even be transmitted to the mobile base 11. The force transmission path is clear and the adaptability is strong, so it can adapt to the force and temperature deformation of the curtain wall unit 20.

[0028] Understandably, when the curtain wall connection member 10 of the present invention is installed, first, the chassis 1121 and the rod 1122 of the moving base 11 can be initially positioned on the installation surface of the building main body 3 after being combined with the cover plate 1111, and the cover plate 1111 is welded and installed on the installation surface of the building main body 3. At this time, the position of the chassis 1121 can be freely adjusted within a certain range in all directions on the plane of the cylindrical accommodating space 1113 of the cover plate 1111 by moving the rod 1122. Then, the locking disc 1112 is installed on the rod 1122 and rotated until it contacts the cover plate 1111. After accurately measuring and repositioning the positions of the rod 1122 and the chassis 1121, torque is applied to the locking disc 1112 until the positions of the chassis 1121 and the cover plate 1111 are locked. At this time, the locking disc 1112 and the cover plate 1111 are welded and fixed, and thus the installation of the moving base 11 is completed. Next, the cylindrical body 121 is installed on the rod 1122. By the cooperation of the internal thread of the cylindrical body 121 and the first thread 1123 on the rod 1122, the connection assembly can be accurately adjusted to the required installation position. In this step, the cylindrical body 121 can rotate on the rod 1122 and can also freely adjust its height on the rod 1122. Then, the kit 123 is sleeved on the connecting member 122, and there is a gap between one end of the kit 123 close to the cylindrical body 121 and the end of the connecting member 122 extending from the cylindrical body 121 to accommodate slight installation deviations of the rod 1122 and subsequent slight processing deviations of the curtain wall unit 20, and it is fixed by the first fastener 125. After the above steps are completed, the second fastener 127 with a matching model is pre-loaded into the card slot 1231, and the position of the second fastener 127 in the card slot 1231 can be freely adjusted according to the installation needs. Next, the second mounting plate 1243 of the pressing block 124 is fixedly installed on the curtain wall unit 20, and then the combination of the pressing block 124 and the curtain wall unit 20 is installed on the corresponding second fastener 127 of the kit 123. Then, through the cooperation of the rack 1244 on the upper surface of the first mounting plate 1242 of the pressing block 124, the serrated lower end of the gasket 126, and the second fastener 127, the combination of the curtain wall unit 20 and the pressing block 124 is locked on the kit 123. In this step, due to the design of the arc surface, the combination can adapt to a certain angle change and can also adapt to the situation where the included angle between adjacent curtain wall units 20 is not 180°. Then, continue to repeat the above steps to complete the installation of all curtain wall units 20, and the pressing blocks 124 on the same kit 123 need to be staggered from each other to avoid conflict.

[0029] Refer to Figures 4 to 5 , Figures 4 to 5Shows a specific embodiment of the curtain wall 1 of the present invention. In the embodiment shown in the drawings, the curtain wall 1 includes a plurality of curtain wall units 20 and a plurality of the curtain wall connection members 10 described in the above embodiments. Each curtain wall unit 20 is installed between two adjacent sets of parts 123 through the cooperation of the first mounting plate 1242 of the pressing block 124 and the second fastener 127. In this embodiment, the curtain wall unit 20 is a triangular grid curtain wall structure, and a curtain wall structure with six sides intersecting at a point can be formed through the connecting assembly 12. The second mounting plate 1243 of the pressing block 124 is fixed to the frame 201 of the curtain wall unit 20 through the fastener 30. It can be understood that the frame 201 of the curtain wall unit 20 can be locked and installed on the set of parts 123 of the connecting assembly 12 through the cooperation of the pressing block 124, the gasket 126 and the second fastener 127. During installation, a certain direction adjustment within the installation plane can be achieved through the cooperation of the chassis 1121, the cover plate 1111 and the locking disc 1112, that is, by moving the position of the chassis 1121 within the accommodating space 1113 of the cover plate 1111, and the height and angle direction adjustments are achieved through the cooperation of the rod member 1122 and the connecting assembly 12. And because there is a gap between the set of parts 123 and the connecting member 122, it can adapt to the slight installation deviation of the rod member 1122 and the slight processing deviation of the subsequent curtain wall unit 20. The position of the curtain wall unit 20 can be further adjusted through the cooperation of the second fastener 127 and the card slot 1231, so as to achieve multi-directional adjustment.

[0030] In summary, the moving and rotating part of the curtain wall connection member of the present invention is located within the fixed and locking part and can move within the plane of the fixed and locking part, so that the moving and rotating part can be freely adjusted within a certain plane direction range. And the cylindrical body in the connecting assembly for connecting with the curtain wall unit is threadedly connected to the moving and rotating part, so that the angle and height of the curtain wall unit can be adjusted. And one side of the pressing block in the connecting assembly is connected to the curtain wall unit, and the other side is installed on the set of parts through the second fastener. And the head of the second fastener is arranged in the card slot of the set of parts and can move in the card slot, so that the position of the pressing block can be adjusted, thereby further adjusting the position of the curtain wall unit. And because the set of parts is sleeved on the connecting member and can move on the connecting member to adapt to the installation deviation and the slight processing deviation of the curtain wall unit, it can be seen that the curtain wall connection member of the present invention can adapt to the complex and variable connection and structural deviation on the construction site of the building body through the cooperation of the moving and rotating part, the fixed and locking part and the connecting assembly.

[0031] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Those skilled in the art can make various equivalent changes and improvements on the basis of the above embodiments. Any equivalent changes or modifications made within the scope of the claims shall fall within the protection scope of the present invention.
