Description

Technical Field

[0001] The invention relates to the technical field of curtain walls, in particular to a multi-stage connection structure of curtain wall aluminum veneers. Background Art

[0002] Curtain wall refers to the non-load-bearing exterior wall enclosure of a building, which is usually composed of panels (glass, metal plates, stone slabs, ceramic plates, etc.) and the supporting structure behind (aluminum beams and columns, steel structures, glass ribs, etc.). The building curtain wall is composed of the supporting structure system and panels, and has a certain displacement capacity relative to the main structure. It is an external protective structure or decorative structure of the building that does not share the effects on the main structure. The aluminum single-plate curtain wall has strong strength and rigidity, which ensures the flatness and wind and earthquake resistance during long-term use.

[0003] According to publication number CN111851807A, publication (announcement) date: 2020.10.30, a prefabricated building curtain wall assembly connection structure is disclosed, which belongs to the field of building curtain walls. The key points of its technical solution include an aluminum alloy beam, a curtain wall panel assembly and at least one group of galvanized steel plates, each group of the galvanized steel plates is composed of two upper and lower L-shaped steel plates, and the two L-shaped steel plates are symmetrically arranged on the wall of the building through expansion bolts. The aluminum alloy beam is fixed between the two L-shaped steel plates through stainless steel bolts, and a mounting module for installing the curtain wall panel assembly is provided on one side of the aluminum alloy beam, and the curtain wall panel assembly is clamped in the interior of the mounting module, and a pressure block for sealing the curtain wall panel assembly is provided on one side of the mounting module, and an aluminum alloy cover plate is clamped on one side of the pressure block. The present invention makes the assembly of the curtain wall assembly more convenient, and the installation and positioning of the curtain wall assembly is very convenient, which greatly shortens the installation time of the curtain wall assembly.

[0004] In the prior art including the above-mentioned patent, the curtain wall panels are fixed by L-shaped steel plates and expansion bolts to connect the vertical ends of the curtain wall panels to the aluminum alloy beams. However, in the actual installation process of the aluminum veneer curtain wall panels, additional bolts need to be welded on the back of the aluminum veneer. After the vertical ends of the aluminum veneer curtain wall are fixed, the welded bolts on the back of the aluminum veneer are fixed to the reinforcing ribs between the columns through nuts. When multiple aluminum veneers are installed and spliced, the welded bolts on the back of the aluminum veneer are completely covered. If a single aluminum veneer in the middle of the curtain wall is damaged by deformation, it can only be disassembled from the aluminum veneer at the edge of the entire curtain wall, and the aluminum veneer at the damaged position can be replaced. Therefore, the presence of the welded bolts on the back of the aluminum veneer makes it impossible to disassemble and replace the existing aluminum veneer curtain wall separately, resulting in a surge in maintenance costs.

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0031] like Figure 1-7 As shown, a curtain wall aluminum single plate multi-stage connection structure includes:

[0032] A column 11 and a crossbeam 12, wherein the crossbeam 12 is vertically arranged on the column 11, a mounting rod 111 is arranged on the column 11, and a supporting portion 1111 is arranged on the mounting rod 111;

[0033] Aluminum curtain plate 2, vertical connection block 13 and connection bolt 14, the aluminum curtain plate 2 is provided with angled portions 21 at both vertical ends, and the connection bolt 14 penetrates the vertical connection block 13 and the angled portions 21 to connect the aluminum curtain plate 2 and the cross beam 12;

[0034] The movable plate 31 and the driving screw 32, the movable plate 31 is slidably set on the installation rod 111, the driving screw 32 is rotatably set on the installation rod 111 to be located on both horizontal sides of the aluminum curtain plate 2, the driving screw 32 is threadedly matched with the movable plate 31, and locking blocks 4 are symmetrically and vertically slidably set on the movable plate 31, the driving screw 32 is driven to rotate to drive the movable plate 31 to slide close to the aluminum curtain plate 2 so that the two locking blocks 4 slide away from each other and embed into the corner portion 21, and the abutment portion 42 of the locking block 4 abuts against the end of the connecting bolt 14.

[0035] like Figure 1 As shown, the columns 11 and the beams 12 are arranged on the outside of the wall to serve as a mounting frame. Figure 2 As shown, the connecting bolts 14 are used to penetrate the vertical connecting blocks 13 to connect the corner portion 21 of the aluminum curtain plate 2 and the cross beam 12 into one body, thereby completing the primary fixed connection of the aluminum curtain plate 2. Figure 3 As shown, a sliding hole 311 is provided on the movable plate 31, and the movable plate 31 is slidably arranged on the mounting rod 111 through the sliding hole 311. A threaded hole 313 is provided on the movable plate 31, and a driving screw 32 is rotatably arranged on the supporting portion 1111 of the mounting rod 111. The driving screw 32 can be rotatably driven so that the movable plate 31 is located on the mounting rod 111 and slides relative to the aluminum curtain plate 2, and the locking block 4 is slidably arranged on the vertical slide groove 316 of the movable plate 31 by setting a vertical sliding portion 44, as shown in FIG. Figure 2 As shown, after the aluminum curtain panel 2 completes the primary fixed connection, the surface of the aluminum curtain panel 2 away from the column 11 is the front side, and the surface of the aluminum curtain panel 2 facing the column 11 is the back side. The support portion 1111 of the mounting rod 111 contacts the back side of the aluminum curtain panel 2 to increase the wind resistance of the aluminum curtain panel 2. Then, the screw rod 32 can be rotated to drive the movable plate 31 to slide close to the aluminum curtain panel 2. At this time, the movable plate 31 slides to drive the two locking blocks 4 to slide away vertically relative to each other, so that the contact portion 42 of the locking block 4 is embedded in the angle portion 21 and contacts the end of the connecting bolt 14 to complete the fixing of the aluminum curtain panel 2. The secondary fixation of the plate 2 further improves the fixing stability of the aluminum curtain panel 2, and because the driving screw rods 32 are located on both sides of the aluminum curtain panel 2 in the horizontal direction, the driving screw rods 32 can also be driven to rotate in the reverse direction to slide the movable plate 31 away from the aluminum curtain panel 2, and the locking block 4 slides away from the angled portion 21 to realize the secondary connection unlocking of the aluminum curtain panel 2, avoiding the problem that the aluminum curtain panel 2 is difficult to disassemble due to traditional welding bolts, thereby realizing the single disassembly and maintenance of the aluminum curtain panel 2 in the whole curtain wall, without the need to disassemble the whole curtain wall, thereby improving the disassembly efficiency and reducing the maintenance cost.

[0036] Secondly, when the locking block 4 is embedded in the angled portion 21, the abutting portion 42 abuts against the end of the connecting bolt 14 to further reinforce the connecting bolt 14, thereby alleviating the loosening of the connecting bolt 14 caused by the vibration generated by the wind, thereby further improving the fixing stability of the aluminum curtain panel 2 and increasing the safety and wind resistance of the curtain wall.

[0037] Furthermore, the locking block 4 is provided with a resisting slope 41, and the supporting portion 1111 is provided with a guiding slope 1112. The movable plate 31 is driven to slide close to the aluminum curtain plate 2 so that the resisting slope 41 resists the guiding slope 1112 to slide so that the locking block 4 slides vertically. Figure 3 and Figure 4 As shown, a guide slope 1112 is provided on the support portion 1111, and a resistance slope 41 is provided on the locking block 4. When the movable plate 31 is driven by the driving screw 32 to slide toward the aluminum curtain panel 2, the locking block 4 moves close to the support portion 1111 so that the resistance slope 41 is resisted against the guide slope 1112, thereby causing the locking block 4 to be pushed to slide vertically and be embedded in the angle portion 21. The guiding slope 1112 and the resistance slope 41 are used to increase the sliding stability of the locking block 4.

[0038] Furthermore, a matching slope 43 is provided on the locking block 4, and the locking block 4 is driven to slide vertically and embed into the inner side of the angle portion 21 so that the matching slope 43 abuts against the chamfered surface at the end of the angle portion 21 and moves. When the locking block 4 slides and embeds into the angle portion 21, the matching slope 43 abuts against the chamfered surface at the end of the angle portion 21 and moves to further improve the sliding stability of the locking block 4, and the matching slope 43 abuts against the angle portion 21 to further improve the locking stability of the locking block 4 on the aluminum curtain panel 2.

[0039] In the above technical solution, the vertical connecting block 13 and the connecting bolt 14 are used as the main connecting components of the aluminum curtain panel 2, and the movable plate 31 and the locking block 4 are used as the secondary connecting components of the aluminum curtain panel 2, thereby improving the fixing stability of the aluminum curtain panel 2. Secondly, the locking block 4 can be fixed or unlocked to the aluminum curtain panel 2 by rotating the driving screw 32 to drive the movable plate 31 to slide, thereby realizing the single disassembly and maintenance of the aluminum curtain panel 2 in the whole curtain wall, without the need to disassemble the whole curtain wall, thereby improving the disassembly efficiency and reducing the maintenance cost.

[0040] As another embodiment provided by the present invention, the movable plate 31 is provided with supporting parts 312 located on both horizontal sides of the aluminum curtain plate 2 .

[0041] Specifically, Figure 3As shown, supporting parts 312 are symmetrically arranged on the movable plate 31 at both horizontal sides of the aluminum curtain plate 2. When the screw rod 32 is rotated to drive the movable plate 31 to slide close to complete the primary fixation of the aluminum curtain plate 2, the supporting parts 312 gradually move close to the horizontal sides of the aluminum curtain plate 2 and get close to it, and the abutting parts 42 of the locking block 4 are embedded in the angled parts 21 and abut against the ends of the connecting bolts 14 to complete the secondary fixation of the aluminum curtain plate 2. At this time, the supporting parts 312 are located in the horizontal directions of both sides of the back side of the aluminum curtain plate 2. When the splicing and installation of multiple aluminum curtain plates 2 are completed, the supporting parts 312 are located under the horizontal splicing seams of the aluminum curtain plates 2 to play a supporting role, so as to facilitate the gluing operation at the joints between the aluminum curtain plates 2, facilitate the sealing and shock-absorbing glue to be formed and fixed at the joints between the aluminum curtain plates 2, and also avoid the sealing and shock-absorbing glue from leaking into between the aluminum curtain plate 2 and the column 11, which causes the colloid to expand and squeeze the aluminum curtain plate 2 to deform, thereby further improving the protection of the aluminum curtain plate 2. Secondly, the driving screw 32 is also located on both sides of the aluminum curtain panel 2 in the horizontal direction. When the multiple aluminum curtain panels 2 are spliced ​​and installed, the hexagonal bolt heads of the driving screw 32 are also located between the joints between the aluminum curtain panels 2. After the joints between the aluminum curtain panels 2 are glued, the glue covers the hexagonal bolt heads of the driving screw 32 to protect the driving screw 32. When the aluminum curtain panel 2 needs to be disassembled and replaced, it is only necessary to remove the glue on the side of the aluminum curtain panel 2 to expose the driving screw 32, and then rotate the driving screw 32 to achieve secondary fixation and unlocking of the aluminum curtain panel 2, thereby improving the disassembly efficiency.

[0042] As another embodiment provided by the present invention, the movable plate 31 is symmetrically and movably provided with tensioning blocks 5, the back side of the aluminum curtain plate 2 is provided with a middle groove 22, the ends of the tensioning blocks 5 are provided with expansion parts 51, and elastic members 92 are provided between the tensioning blocks 5. The movable plate 31 is driven to slide close to the aluminum curtain plate 2 so that the tensioning blocks 5 slide relatively away, and the two expansion parts 51 extend into and expand in the middle groove 22.

[0043] Specifically, Figure 2As shown, the tension block 5 is movably arranged on the movable plate 31, and a middle groove 22 is opened on the back side of the aluminum curtain panel 2. When the screw rod 32 is rotated and driven, the movable plate 31 is driven to slide close to the aluminum curtain panel 2, and the movable plate 31 drives the tension block 5 to move so that the expansion part 51 of the tension block 5 extends into the middle groove 22. As the movable plate 31 continues to slide, the tension block 5 is driven to slide away relatively so that the expansion part 51 is expanded in the middle groove 22, thereby realizing that the movable plate 31, the tension block 5 and the aluminum curtain panel 2 are expanded into one, thereby improving the tensile resistance of the aluminum curtain panel 2 when the installation is completed, and further improving the stability of the curtain wall. Secondly, since a middle groove 22 is provided in the middle of the aluminum curtain panel 2, and the aluminum curtain panel 2 is a metal plate with large thermal stress, when the aluminum curtain panel 2 is deformed by heat, the aluminum curtain panel 2 is more easily deformed toward the side of the middle groove 22 due to the thermal stress, and the expansion portion 51 applies a tensile force to the aluminum curtain panel 2 to offset the pressure of the aluminum curtain panel 2 deforming toward the middle groove 22, thereby reducing the thermal stress on the corner portion 21 of the aluminum curtain panel 2 and the connecting bolt 14, thereby improving the fixing stability of the connecting bolt 14, avoiding the problem of the connecting bolt 14 breaking due to the thermal stress deformation at both ends of the aluminum curtain panel 2, reducing the pressure of the aluminum curtain panel 2 bulging toward the outer shape, and improving the safety and service life of the aluminum curtain panel 2.

[0044] Secondly, if Figure 7 As shown, an elastic member 92 is provided between the tensioning blocks 5. When the aluminum curtain panel 2 is deformed away from the middle groove 22 due to thermal stress, the side wall of the middle groove 22 will apply a relatively close pressure to the tensioning blocks 5. The elastic member 92 is located between the tensioning blocks 5 and plays a buffering role for the thermal stress of the aluminum curtain panel 2, further avoiding the problem of deformation and bending of the aluminum curtain panel 2.

[0045] Among them, the side wall of the middle groove 22 is concave arc-shaped, and the contact surface between the expansion part 51 and the side wall of the middle groove 22 is convex arc-shaped, thereby increasing the expansion force between the expansion part 51 and the middle groove 22, improving the fixing stability of the tension block 5 on the aluminum curtain panel 2, and the elastic member 92 can be replaced by springs, airbags, elastic plates and other elastic objects known to those skilled in the art.

[0046] Furthermore, a mounting groove 315 is provided on the movable plate 31, a sliding seat 91 is vertically slidably provided in the mounting groove 315, a horizontal sliding portion 911 is provided on the sliding seat 91, a horizontal sliding groove 53 is provided on the tensioning block 5, the horizontal sliding portion 911 is slidably assembled with the horizontal sliding groove 53, a separation guide slope 54 is provided on the tensioning block 5, a triangular column-shaped push portion 314 is provided on the movable plate 31, and the movable plate 31 is driven to slide close to the aluminum curtain panel 2 so that the push portion 314 pushes the tensioning block 5 through the separation guide slope 54 to slide relatively away. When the screw rod 32 is rotated to drive the movable plate 31 to slide close to the aluminum curtain panel 2, the movable plate 31 first drives the tensioning block 5 to move closer to the middle groove 22. When the end of the tensioning block 5 contacts the bottom of the middle groove 22, the pushing portion 314 of the movable plate 31 contacts the separation guide slope 54 of the tensioning block 5 to push the tensioning block 5 and the sliding seat 91 to slide away from each other, thereby causing the expansion portion 51 to expand in the middle groove 22, and a spring is provided in the movable plate 31 to drive the sliding seat 91 to slide close and reset.

[0047] As another embodiment provided by the present invention, it also includes a flexible push plate 6, a first end of the flexible push plate 6 is fixedly connected to the tensioning block 5, and a second end is fixedly connected to the locking block 4 so that the flexible push plate 6 is arc-shaped, and the movable plate 31 is driven to slide close to the aluminum curtain panel 2 so that the locking block 4 slides away from the tensioning block 5 so that the flexible push plate 6 is deformed and elongated.

[0048] Specifically, Figure 2 As shown, Figure 5 As shown, the end of the flexible push plate 6 facing the tension block 5 is the first end, and the end facing the locking block 4 is the second end. Figure 2As shown, the first end of the flexible push plate 6 is fixedly connected to the tension block 5, and the second end is fixedly connected to the locking block 4 so that the flexible push plate 6 is bent in an arc shape. When the movable plate 31 is driven to slide close to the aluminum curtain panel 2, the locking block 4 slides away relatively to be embedded in the angled portion 21, and the tension block 5 is driven to slide away relatively to make the expansion portion 51 expand and tighten in the middle groove 22. At this time, the relative distance between the tension block 5 and the locking block 4 increases so that the flexible push plate 6 is deformed and elongated. At this time, the flexible push plate 6 can apply a vertical thrust to the locking block 4 so that the locking block 4 slides and is embedded in the angled portion 21, thereby improving the connection stability of the locking block 4 embedded in the angled portion 21. When the locking block 4 After sliding into the angled portion 21 to complete the secondary fixed connection of the aluminum curtain panel 2, the flexible push plate 6 is located between the tension block 5 and the locking block 4 in an arc shape. When the aluminum curtain panel 2 is deformed away from the middle groove 22 due to thermal stress, the side wall of the middle groove 22 will apply a relatively close pressure to the tension block 5, and the tension block 5 slides relatively close due to the pressure. At this time, the vertical thrust applied by the flexible push plate 6 to the locking block 4 is reduced, so that the thrust of the locking block 4 on the connecting bolt 14 and the angled portion 21 is reduced, thereby reducing the fixing pressure at both ends of the aluminum curtain panel 2, thereby further avoiding the problem of fracture of the aluminum curtain panel 2 at both ends due to excessive pressure when subjected to thermal stress, thereby improving the safety of use;

[0049] Secondly, when the temperature drops and the aluminum curtain panel 2 shrinks in volume due to the cooling, the aluminum curtain panel 2 is subjected to tension at both ends due to the cooling and shrinkage. Therefore, the side wall of the middle groove 22 no longer applies relatively close pressure to the tension block 5. At this time, the elastic member 92 drives the tension block 5 to slide relatively away so that the expansion portion 51 is further expanded and tightened in the middle groove 22. The tension block 5 is reduced in distance from the locking block 4 due to sliding. The flexible push plate 6 is compressed and deformed to increase the vertical thrust on the locking block 4. At this time, the locking block 4 further applies pressure to the corner portions 21 at both ends of the aluminum curtain panel 2 to offset the tension of the aluminum curtain panel 2 due to the cooling and shrinkage, thereby avoiding damage to the panel surface caused by the cooling and shrinkage of the aluminum curtain panel 2, and further improving the safety and service life of the curtain wall. Therefore, the flexible push plate 6, the tension block 5 and the locking block 4 are used to realize the adaptive change of the installation pressure at both ends of the aluminum curtain panel 2 when the aluminum curtain panel 2 is deformed by temperature, thereby improving the installation stability of the aluminum curtain panel 2 and the flatness after installation.

[0050] As another embodiment provided by the present invention, it also includes an arc-shaped slide plate 7, an arc-shaped slide groove 52 is opened on the tension block 5, the first end of the arc-shaped slide groove 52 is an extension opening 521, and the extension opening 521 faces the side wall of the middle groove 22. The arc-shaped slide plate 7 is slidably arranged in the arc-shaped slide groove 52 so that the first end of the arc-shaped slide plate 7 abuts against the side wall of the middle groove 22, and the second end of the arc-shaped slide plate 7 abuts against the back side surface of the aluminum curtain panel 2.

[0051] Specifically, Figure 5As shown, the tension block 5 is provided with an arc-shaped slot 52, and a first end of the arc-shaped slot 52 is provided with a protruding opening 521. When the movable plate 31 is driven to slide close to the aluminum curtain plate 2 to complete the secondary fixed connection to the aluminum curtain plate 2, the tension block 5 is driven to slide relatively away so that the expansion portion 51 is expanded and tightened in the middle groove 22, and the protruding opening 521 moves toward the side wall of the middle groove 22, and the arc-shaped slide plate 7 is slidably disposed in the arc-shaped slot 52. At this time, as shown in FIG. Figure 7 As shown, the end of the arc-shaped slide plate 7 close to the middle groove 22 is the first end, and the end away from the middle groove 22 is the second end. The first end of the arc-shaped slide plate 7 abuts against the side wall of the middle groove 22, and the second end of the arc-shaped slide plate 7 abuts against the back side of the aluminum curtain panel 2. The arc-shaped slide plate 7 can be used as a secondary horizontal reinforcement rib to abut against the back side of the aluminum curtain panel 2. When the middle part of the aluminum curtain panel 2 is subjected to wind pressure and bends toward the side of the column 11, the first end of the arc-shaped slide plate 7 is compressed and slides into the arc-shaped slide groove 52, but the second end of the arc-shaped slide plate 7 slides toward the vertical sides of the middle part of the aluminum curtain panel 2 to increase the wind resistance of the middle part of the aluminum curtain panel 2, thereby further improving the safety of the curtain wall. Secondly, when the aluminum curtain panel 2 is deformed and bent toward the side of the middle groove 22 due to thermal stress, the side wall of the middle groove 22 applies pressure to the first end of the arc-shaped slide plate 7 so that the second end of the arc-shaped slide plate 7 slides toward the middle vertical sides of the aluminum curtain panel 2 to resist, thereby causing a gap between the tension block 5 and the aluminum curtain panel 2 due to the push of the arc-shaped slide plate 7. The gap between the tension block 5 and the aluminum curtain panel 2 can be used as a deformation expansion joint to avoid the deformation and collapse of the aluminum curtain panel 2. Furthermore, there is air between the gap between the tension block 5 and the aluminum curtain panel 2 as a poor conductor of heat, so that when the aluminum curtain panel 2 is subjected to high temperature, the thermal stress at the middle position of the aluminum curtain panel 2 is greater than the thermal stress at the two ends, thereby avoiding the aluminum curtain panel 2 detachment caused by the breakage or arching of the corner portion 21 of the aluminum curtain panel 2 and the connection bolt 14 due to thermal stress, thereby further improving the protection of the aluminum curtain panel 2.

[0052] Secondly, when the aluminum curtain plate 2 needs to be disassembled, the driving screw 32 is rotated in the reverse direction to make the movable plate 31 slide away from the aluminum curtain plate 2. At this time, the tension block 5 is driven to slide closer so that the expansion portion 51 is relatively close to be separated from the middle groove 22. At this time, if there is still deformation stress on the aluminum curtain plate 2 so that the side walls of the middle groove 22 have a tendency to be relatively close, the first end of the arc-shaped slide plate 7 will be stressed and temporarily stuck between the middle grooves 22, and as the movable plate 31 gradually slides away, the tension block 5 is relatively close. The arc-shaped slide plate 7 is brought close to and separated from the middle groove 22, so that when the aluminum curtain panel 2 damaged by deformation is disassembled, the expansion portion 51 first moves away from the middle groove 22, and the arc-shaped slide plate 7 slides so that the end portion is still stuck on the middle groove 22, and then the arc-shaped slide plate 7 is separated from the middle groove 22, thereby avoiding the aluminum curtain panel 2 from being ejected outwards and deformed and bulged due to the instantaneous reaction force generated by the tension block 5 being instantly separated from the aluminum curtain panel 2, thereby improving the safety when disassembling the damaged aluminum curtain panel 2.

[0053] As another embodiment provided by the present invention, it also includes a push rod 8, which is horizontally arranged on the clamping portion 61 of the flexible push plate 6, and the movable plate 31 is located at the position closest to the aluminum curtain plate 2 during the sliding stroke to enable the flexible push plate 6 to be deformed until the push rod 8 contacts the back side of the aluminum curtain plate 2.

[0054] Specifically, Figure 7 As shown, the push rod 8 is arranged on the clamping portion 61 of the flexible push plate 6. When the screw rod 32 is rotated to drive the movable plate 31 to slide to the position closest to the aluminum curtain panel 2, the locking block 4 slides and embeds into the angle portion 21, and the expansion portion 51 of the tension block 5 is expanded and tightened in the middle groove 22 to complete the secondary fixed connection of the aluminum curtain panel 2. At this time, the flexible push plate 6 is deformed by the sliding of the tension block 5 and the locking block 4 so that the push rod 8 contacts the back side of the aluminum curtain panel 2. At this time, the push rod 8 contacts the side of the aluminum curtain panel 2 as a horizontal reinforcement rib to further reduce the vertical bending deformation of the aluminum curtain panel 2, thereby further improving the fixing stability of the aluminum curtain panel 2.

[0055] As another embodiment provided by the present invention, a plurality of protrusions 71 are arranged in a circular array on the arc-shaped slide plate 7. The movable plate 31 slides away from the aluminum curtain plate 2 from the position closest to the aluminum curtain plate 2 during the sliding stroke, driving the flexible push plate 6 to deform, bend and shorten so that the stop rod 8 contacts and passes over the plurality of protrusions 71.

[0056] Specifically, Figure 3As shown, a plurality of protrusions 71 are arranged in a circumferential array on the arc-shaped slide plate 7. When the aluminum curtain plate 2 is initially fixedly connected by the vertical connection block 13 and the connection bolt 14, the screw rod 32 is rotated to drive the movable plate 31 to slide close to the aluminum curtain plate 2. At this time, the flexible push plate 6 is deformed and elongated by the relative sliding between the tension block 5 and the locking block 4. At this time, the push rod 8 sequentially contacts and passes over the plurality of protrusions 71 to move close to the back side of the aluminum curtain plate 2. At this time, the shaking energy generated when the push rod 8 contacts and separates from the protrusion 71 is transmitted to the tension block 5 and the locking block 4, thereby facilitating the sliding of the locking block 4 into the folded corner. The part 21 can also facilitate the expansion part 51 to move and expand in the middle groove 22. When the aluminum curtain panel 2 needs to be disassembled, the movable plate 31 slides away from the aluminum curtain panel 2, and the flexible push plate 6 is deformed, bent and shortened to make the push rod 8 contact and pass over the plurality of protrusions 71 away from the aluminum curtain panel 2. At this time, the vibration energy generated by the contact and separation of the push rod 8 and the protrusion 71 is transmitted to the tensioning block 5 to facilitate the contact and separation between the expansion part 51 and the side wall of the middle groove 22, thereby avoiding the problem of rust resistance at the contact position between the expansion part 51 and the middle groove 22 and difficulty in separation, thereby improving the disassembly stability of the aluminum curtain panel 2.

[0057] Working principle: the column 11 and the crossbeam 12 are arranged on the outside of the wall as a mounting base, and the connecting bolt 14 is used to penetrate the vertical connecting block 13 to connect the angled portion 21 of the aluminum curtain panel 2 and the crossbeam 12 into one body, so as to complete the primary fixed connection of the aluminum curtain panel 2, and the driving screw 32 is turned to drive the movable plate 31 to slide close to the aluminum curtain panel 2. At this time, the movable plate 31 slides to drive the two locking blocks 4 to slide vertically relative to each other, so that the contact portion 42 of the locking block 4 is embedded in the angled portion 21 and contacts the end of the connecting bolt 14 to complete the secondary fixation of the aluminum curtain panel 2, and the contact portion 42 contacts the end of the connecting bolt 14 to further reinforce the connecting bolt 14. As the movable plate 31 continues to slide, the tension block 5 is driven to slide relatively. The expansion portion 51 is moved away from the middle groove 22 so that the expansion portion 51 is expanded and tightened in the middle groove 22. The flexible push plate 6 is deformed by the sliding of the tension block 5 and the locking block 4 so that the push rod 8 is pressed against the back side of the aluminum curtain plate 2. At this time, the push rod 8 is pressed against the side of the aluminum curtain plate 2 as a horizontal reinforcing rib. The first end of the arc-shaped slide plate 7 is pressed against the side wall of the middle groove 22, and the second end of the arc-shaped slide plate 7 is pressed against the back side of the aluminum curtain plate 2. The arc-shaped slide plate 7 can be used as a secondary horizontal reinforcing rib to press against the back side of the aluminum curtain plate 2; the supporting portion 312 is located on both sides of the horizontal side of the back side of the aluminum curtain plate 2. When the splicing and installation of multiple aluminum curtain plates 2 are completed, the supporting portion 312 is located under the horizontal splicing seam of the aluminum curtain plate 2 to play a supporting role, thereby facilitating the gluing operation at the joints between the aluminum curtain plates 2;

[0058] When it is necessary to disassemble a single aluminum curtain panel 2, the colloid on the side of the aluminum curtain panel 2 is removed to expose the driving screw 32, and then the driving screw 32 is rotated to slide the movable plate 31 away from the aluminum curtain panel 2. At this time, the tension block 5 is driven to slide closer so that the expansion portion 51 is relatively close to disengage from the middle groove 22, and the arc-shaped slide plate 7 slides so that the end is still stuck on the middle groove 22, and then the arc-shaped slide plate 7 is disengaged from the middle groove 22 again, and the flexible push plate 6 is deformed, bent and shortened to make the push rod 8 contact and pass over several protrusions 71 away from the aluminum curtain panel 2. At this time, the vibration energy generated by the contact and separation of the push rod 8 and the protrusion 71 is transmitted to the tension block 5 to facilitate the contact and separation between the expansion portion 51 and the side wall of the middle groove 22, and the locking block 4 slides away from the angle portion 21 to realize the secondary fixation unlocking of the aluminum curtain panel 2, and then the connecting bolt 14 is unlocked to realize the disassembly of the aluminum curtain panel 2.

[0059] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
