Description

Technical Field

[0001] The present invention relates to the technical field of aluminum single - panel curtain walls, and more specifically to a connection structure for an aluminum single - panel curtain wall and a curtain wall system. Background Art

[0002] Curtain wall aluminum single - panel is a new type of curtain wall material made of aluminum alloy as the base material and sprayed with decorative materials on the surface. During installation, connection components such as keels or angle codes are first installed, and then the aluminum single - panel is installed on the connection components by means of snap - fitting or fastening.

[0003] According to the patent number CN212129635U, publication (announcement) date: December 11, 2020, a snap - on plate installation structure is disclosed, which includes a snap - on frame. A snap - on member is snap - fitted on the snap - on frame. A connecting member is provided at the bottom of the snap - on member. The connecting member is connected to an aluminum single - panel through a second connecting bolt. An installation frame is provided on the upper end surface of the snap - on frame. A hoisting component for installing the aluminum single - panel is provided on the main keel. Dust - proof protrusions are symmetrically provided on the front and rear end faces of the aluminum single - panel, and dust - proof grooves adapted to the dust - proof protrusions are provided on the left and right end faces of the aluminum single - panel. This snap - on plate installation structure facilitates preventing gaps between two adjacent aluminum single - panels during installation through the dust - proof protrusions and dust - proof grooves on both sides of the aluminum single - panel, thereby preventing dust from falling on the roof and maintaining the cleanliness of the interior. The stability of the connection between the snap - on member and the snap - on frame is improved through the positioning bolt, preventing the aluminum single - panel from falling and causing potential safety hazards. The positioning of the aluminum single - panel during installation is facilitated through the card slot and snap - buckle protrusions, improving the construction quality, and it has strong practicability.

[0004] In the prior art including the above - mentioned patent, compared with the fastening connection method, snap - on installation has a faster installation speed, better aesthetics, and is convenient for subsequent disassembly and maintenance. However, due to appearance requirements, the size of the aluminum single - panel surface needs to be increased, and in an environment where disassembly and maintenance are required frequently, the load borne by the snap - fasteners will increase, easily causing the aluminum single - panel with a larger panel to become loose, and it is not easy to perform snap - on operations on a larger area, easily leaving large gaps. Summary of the Invention

[0005] The purpose of the present invention is to provide a connection structure for an aluminum single - panel curtain wall and a curtain wall system, aiming to solve the problems of loosening and gaps in the snap - on installation of aluminum single - panels with a larger area.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A connection structure for an aluminum single - panel curtain wall, comprising:

[0007] Fixed card slots, which are respectively opened at both ends of the plate body in the vertical direction;

[0008] Connection skeleton, which includes a plurality of fixed plates arranged in a vertical linear array, and a clamping portion is provided on the fixed plate and is clamped in one of the fixed card slots;

[0009] Pre-fixing mechanism, which includes a pulling rod and a guiding rod that are hinged to each other, and an outward-expanding chuck is provided at the hinge point of the two.

[0012] Preferably, a ring cover and a spring are provided at the second end of the pulling rod. A rotating sleeve is provided on the first rotating plate and is rotatably connected to the ring cover. A rotating pushing plate is rotatably connected to the ring cover. The rotating pushing plate is driven to rotate to store energy in the spring and, as the spring rebounds, push against the first rotating plate to flip it.

[0013] Preferably, the connection skeleton further includes a top lining plate provided on the top of the plate body and an elastic arc plate provided on the bottom of the plate body. The plate body is driven to fit against the wall, so as to push the pulling rod and the guiding rod to fit against the wall and move away from each other, and make the plate body close to the adjacent plate body at the bottom, so that the elastic arc plate is clamped on another top lining plate.

[0014] Preferably, a retention card slot for clamping the guiding rod is provided on the top lining plate.

The tension rods, the guide rods and the connecting framework are hoop - clamped into a triangle within the spacer area, and a ventilation unit and a heat - insulation unit are arranged in the spacer area.

[0019] In the above - mentioned technical solution, the aluminum single - panel curtain wall connection structure and curtain wall system provided by the present invention have the following beneficial effects: Before fixing a relatively large - sized panel body, the outer - expanding chuck is expanded and clamped into one of the fixed chucks to pre - fix the panel body. Subsequently, the panel body is moved for pulling support and guiding, avoiding the loosening of the panel body, and the guiding can also improve the accuracy of the buckle, thereby reducing the gap.

[0033] In order to make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Apparently, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0034] Embodiment 1

[0035] As Figure 1-10 shown, an aluminum single-panel curtain wall connection structure is applied to fix a plate body 1 with a specification of more than 1000mm X 1000mm, and includes:

[0036] Fixed card slots 12, which are respectively opened at both ends of the plate body 1 in the vertical direction;

[0037] Connecting framework 3, which includes a plurality of fixed plates 31 arranged in a linear array in the vertical direction, and a buckling part 32 that is arranged on the fixed plate 31 and is buckled in one of the fixed card slots 12;

[0038] Pre-fixing mechanism 2, which includes a pull rod 21 and a guide rod 22 that are hinged to each other, and an outer expanding chuck 23 is arranged at the hinge point between the two. The outer expanding chuck 23 is driven to be buckled in the other fixed card slot 12, and a pulling member is movably connected between the pull rod 21 and the fixed plate 31.

[0039] Specifically, fixed card slots 12 are provided at both the top and bottom ends of the plate body 1 in the installation direction. The connecting skeletons 3 correspond to the plate bodies 1 one by one. A retention cylinder 320 is provided on the snap part 32, and a limiting groove 321 is opened. The limiting groove 321 is used to guide the movement of the guide rod 22. When fixing the plate body 1, first pull the outwardly expanding chuck 23 (i.e., the hinge point of the pull rod 21 and the guide rod 22) away from the wall, and fix the outwardly expanding chuck 23 to the fixed card slot 12 at the top of the plate body 1. Subsequently, push against the bottom of the plate body 1, push the bottom fixed card slot 12 towards the retention cylinder 320 and then push against the top of the plate body 1. At this time, the non-hinge points of the pull rod 21 and the guide rod 22 expand outward. As the outwardly expanding guide rod 22 is restricted, the plate body 1 will move downward in the vertical direction, so that the retention cylinder 320 is snapped into the fixed card slot 12, completing the installation of the plate body 1.

[0040] In the above technical solution, before fixing the plate body 1 with a larger size, the outwardly expanding chuck 23 is expanded outward and snapped into one of the fixed card slots 12 to pre-fix the plate body 1. Subsequently, when moving the plate body 1 for pulling support and guiding, the situation of the plate body 1 loosening is avoided, and the guiding can also increase the accuracy of the snap, thereby reducing the gap.

[0041] As an embodiment provided by the present invention, the pulling member includes a convex plate 33 provided on the fixed plate 31 and an elastic telescopic rod 24 provided on the convex plate 33. A rotating sliding seat 241 is rotatably connected to the elastic telescopic rod 24. The pull rod 21 is slidably connected to the rotating sliding seat 241, and the first end of the pull rod 21 is slidably connected to the fixed plate 31.

[0042] Specifically, the elastic telescopic rod 24 is driven by the internal elastic member to push downward in the vertical direction. The first end of the pull rod 21 ( Figure 4 for reference, the first end is the lower end, the second end is the upper end, that is, the hinge end), on the fixed plate 31, the pull rod 21 is slidably connected to the rotating sliding seat 241. When the pull rod 21 flips with the push of the plate body 1, it will drive the rotating sliding seat 241 to rotate and slide along the rotating sliding seat 241. After the bottom of the plate body 1 is fixed, push against the top of the plate body 1 to cooperate with the force of the elastic telescopic rod 24 extending, and move the plate body 1 downward. When the fixed card slot 12 at the bottom of the plate body 1 is snapped onto the retention cylinder 320, the elastic telescopic rod 24 will continue to push downward to drive the pull rod 21 to expand outward, thereby pulling the plate body 1 close to the wall to avoid loosening and reduce the outward expansion.

[0043] When fixing, first pull the external clamp 23 to overcome the pushing force of the elastic telescopic rod 24, away from the wall, and fix the external clamp 23 on the fixed slot 12 at the top of the plate body 1, and then push it against the bottom of the plate body 1, and push the fixed slot 12 at the bottom toward the retention cylinder 320 and then push it against the top of the plate body 1. At this time, the non-hinge points of the pulling rod 21 and the guide rod 22 are stretched outward with the force of the elastic telescopic rod 24. As the guide rod 22 is stretched outward, it will be restricted, so that the plate body 1 will move downward in the vertical direction, so that the retention cylinder 320 is clamped on the fixed slot 12, and the installation of the plate body 1 is completed.

[0044] As an embodiment provided by the present invention, the external clamping head 23 includes a first rotating plate 231 and a second rotating plate 232. The first rotating plate 231 is driven to flip away from the second rotating plate 232 and fits the fixed clamping slot 12 for fixing.

[0045] The second end of the pulling rod 21 is provided with a ring cover 211 and a spring 2331. The first rotating plate 231 is provided with a rotating sleeve 2311 rotatably connected to the ring cover 211. The ring cover 211 is rotatably connected with a rotating push plate 234. The rotating push plate 234 is driven to rotate by the energy storage spring 2331 and pushes the first rotating plate 231 to flip as the spring 2331 rebounds.

[0046] Specifically, the second end of the pulling rod 21 is provided with a ring cover 211 and a spring 2331. Figure 4 For reference, the first end is the lower end, and the second end is the upper end, that is, the hinged end). The rotating push plate 234 is provided with a one-way push head 2341 to Figure 6 For reference, when rotating counterclockwise, the one-way push head 2341 will pass over the first rotating plate 231, thereby storing energy in the spring 2331, and when the rotation ends, the spring 2331 rebounds. At this time, the one-way push head 2341 will push the first rotating plate 231 to flip over and fix it with the expansion. During installation, first extend the expansion clamp 23 into the fixed slot 12, and rotate the rotating push plate 234 to store energy in the spring 2331, and then the spring 2331 rebounds to make the first rotating plate 231 flip away from the second rotating plate 232 and fit into the fixed slot 12 for fixation. When the plate body 1 moves in the vertical direction, the spring 2331 can push the first rotating plate 231 to always fit into the fixed slot 12 for fixation to prevent loosening.

[0047] When fixing, first pull the expansion chuck 23 to overcome the pushing force of the elastic telescopic rod 24, move away from the wall, place the expansion chuck 23 in the fixing slot 12, and rotate the rotating pushing plate 234 to store energy in the spring 2331. Then, the spring 2331 rebounds to make the first rotating plate 231 flip away from the second rotating plate 232 and fit against the fixing slot 12 for fixing. Subsequently, push the bottom of the plate body 1, push the bottom fixing slot 12 towards the retention cylinder 320, and then push the top of the plate body 1. At this time, with the force of the elastic telescopic rod 24 extending, the pulling rod 21 and the guiding rod 22 expand outward at non-hinged points. As the outward expansion of the guiding rod 22 is restricted, the plate body 1 will move downward along the vertical direction, causing the retention cylinder 320 to be clamped on the fixing slot 12, completing the installation of the plate body 1.

[0048] As an embodiment provided by the present invention, the connecting skeleton 3 further includes a top lining plate 11 provided on the top of the plate body 1 and an elastic arc plate 13 provided on the bottom of the plate body 1. The plate body 1 is driven to fit against the wall to push the pulling rod 21 and the guiding rod 22 to fit against the wall and move away from each other, and make the plate body 1 close to the adjacent plate body 1 at the bottom, so that the elastic arc plate 13 is clamped on another top lining plate 11.

[0049] The top lining plate 11 is provided with a retention slot for the guiding rod 22 to be clamped.

[0050] Specifically, a sliding slot 111 is provided on the top lining plate 11 at the top of the plate body 1. The top lining plate 11 is an elastic metal plate. During installation, the installation sequence is from bottom to top. Before fixing the expansion chuck 23, first clamp the guiding rod 22 on the retention slot on the guiding rod 22, and then fix the expansion chuck 23. When the guiding rod 22 moves away from the pulling rod 21 with the pushing of the plate body 1 (that is, the non-hinged points of the two move away from each other), the guiding rod 22 will pull the elastic top lining plate 11 to be tensioned. At the same time, the plate body 1 moves downward to clamp the elastic arc plate 13 at the bottom of the plate body 1 into the sliding slot 111 on the top lining plate 11 for coupling, increasing the connection between the two plate bodies 1.

[0051] When fixing, first pull the outer expansion chuck 23 to overcome the pushing force of the elastic telescopic rod 24, move away from the wall, and engage the guiding rod 22 with the retention card slot on the guiding rod 22. Then place the outer expansion chuck 23 in the fixing card slot 12, and rotate the rotating pushing plate 234 to store energy in the spring 2331. Then the spring 2331 rebounds to make the first rotating plate 231 flip away from the second rotating plate 232 and fit against the fixing card slot 12 for fixing. Subsequently, push the bottom of the pushing plate body 1, push the bottom fixing card slot 12 towards the retention cylinder 320 and then push the top of the pushing plate body 1. At this time, with the force of the elastic telescopic rod 24 extending, the non-hinged points of the pull rod 21 and the guiding rod 22 expand outward. As they expand outward, the guiding rod 22 will pull the elastic top lining plate 11 to be tightened. At the same time, the guiding rod 22 will be restricted, causing the plate body 1 to move downward in the vertical direction, so that the retention cylinder 320 is engaged with the fixing card slot 12, completing the installation of the plate body 1.

[0052] As an embodiment provided by the present invention, the first rotating plate 231 and the second rotating plate 232 rotate and remain tightened as the plate body 1 approaches the wall.

[0053] The second rotating plate 232 is arranged on the guiding rod 22. A base rotating column 221 passing through the ring cover 211 is arranged on the guiding rod 22. The spring 2331 is arranged between the base rotating column 221 and the rotating pushing plate 234.

[0054] Specifically, the second rotating plate 232 will rotate with the rotation of the hinge point to increase the distance between the first rotating plate 231 and the second rotating plate 232. The spring 2331 is arranged between the base rotating column 221 and the rotating pushing plate 234. When the second rotating plate 232 rotates with the guiding rod 22, the base rotating column 221 will also rotate simultaneously to prevent the spring 2331 pulling the first rotating plate 231 from being too tight. The rotation angle of the second rotating plate 232 is the same as the rotation angle of the base rotating column 221.

[0055] Furthermore, when the first rotating plate 231 is installed, the external tension mainly generated by the first rotating plate 231 being pushed by the spring 2331 to rotate is used to fix the plate body 1 at this time. After installation, the energy stored in the spring 2331 is gradually eliminated by the rotating base rotating column 221. At the same time, the second rotating plate 232 will flip to push the plate body 1 to move downward in the vertical direction to cooperate with the top lining plate 11 to fix the plate body 1, and at the same time further reduce the situation of gaps and looseness.

[0056] When fixing, first pull the expansion chuck 23 to overcome the pushing force of the elastic telescopic rod 24, move away from the wall, and engage the guiding rod 22 with the retention slot on the guiding rod 22. Then place the expansion chuck 23 into the fixing slot 12, and rotate the pushing plate 234 to store energy in the spring 2331. Then the spring 2331 rebounds to make the first rotating plate 231 flip away from the second rotating plate 232 and fit against the fixing slot 12 for fixation. Subsequently, push the bottom of the pushing plate body 1, push the bottom fixing slot 12 towards the retention cylinder 320 and then push the top of the pushing plate body 1. At this time, with the force of the elastic telescopic rod 24 extending, the non-hinged points of the pulling rod 21 and the guiding rod 22 expand outwards. Along with the outward expansion, the guiding rod 22 will pull the elastic top lining plate 11 to be tightened. At the same time, the guiding rod 22 will be restricted, so that the plate body 1 will move downward in the vertical direction, making the retention cylinder 320 engage with the fixing slot 12. During the outward expansion, the energy stored in the spring 2331 is gradually eliminated by the rotating base rotating column 221. At the same time, the second rotating plate 232 will flip to push the plate body 1 to move downward in the vertical direction to cooperate with the top lining plate 11 to fix the plate body 1 and complete the installation of the plate body 1.

[0057] As the optimal embodiment provided by the present invention, the rotating pushing plate 234 is slidably connected to the rotating ring 233, the spring 2331 is arranged on the rotating ring 233, and a perforation for unlocking is provided on the base rotating column 221.

[0058] Specifically, a sliding column 2342 is arranged on the rotating pushing plate 234, the sliding column 2342 is slidably connected to the rotating ring 233, and the spring 2331 is fixed between the rotating ring 233 and the base rotating column 221. When unlocking is required, insert a screwdriver through the perforation for unlocking provided on the base rotating column 221 to push the rotating pushing plate 234 to slide along the sliding column 2342 and move away from the rotating ring 233, thereby decoupling the first rotating plate 231 for unlocking to disassemble the plate body 1.

[0059] When fixing, first pull the expansion chuck 23 to overcome the pushing force of the elastic telescopic rod 24, move away from the wall, and engage the guiding rod 22 with the retention slot on the guiding rod 22. Then place the expansion chuck 23 into the fixing slot 12, and rotate the pushing plate 234 to store energy in the spring 2331. Then the spring 2331 rebounds to make the first rotating plate 231 flip away from the second rotating plate 232 and fit against the fixing slot 12 for fixation. Subsequently, push the bottom of the pushing plate body 1, push the bottom fixing slot 12 towards the retention cylinder 320 and then push the top of the pushing plate body 1. At this time, with the force of the elastic telescopic rod 24 extending, the non-hinged points of the pulling rod 21 and the guiding rod 22 expand outward. Along with the outward expansion, the guiding rod 22 will pull the elastic top lining plate 11 to be tightened. At the same time, the guiding rod 22 will be restricted, causing the plate body 1 to move downward in the vertical direction, so that the retention cylinder 320 is engaged with the fixing slot 12. During the outward expansion, the force stored in the spring 2331 is gradually eliminated by the rotating base rotating column 221. At the same time, the second rotating plate 232 will flip to push the plate body 1 to move downward in the vertical direction to cooperate with the top lining plate 11 to fix the plate body 1, completing the installation of the plate body 1. When disassembling is required, insert a screwdriver through the perforation provided on the base rotating column 221 for unlocking to push the rotating pushing plate 234 to slide along the rotating ring 233 to decouple the first rotating plate 231 for unlocking and disassemble the plate body 1.
