Technical Field

[0001] The present invention relates to the field of curtain walls, and more particularly to a combined curtain wall and a use method thereof. Background Art

[0002] Curtain wall is the outer wall of the building, which is non-load-bearing and is hung like a curtain, so it is also called "curtain wall". It is a lightweight wall with decorative effect commonly used in modern large and high-rise buildings. It is composed of panels and supporting structure systems, and can have a certain displacement ability relative to the main structure or a certain deformation ability itself, and is an external protective structure or decorative structure of the building that does not bear the effects of the main structure (the external wall frame support system is also a type of curtain wall system).

[0003] In places where lighting requirements are not high (such as warehouses), large opaque curtain walls are installed on the walls of the house for decorative purposes. Generally, one curtain wall can cover the entire wall. The content on the curtain wall is mostly advertisements. Large opaque curtain walls have significant advantages in displaying advertisements. Compared with traditional stickers, the curtain wall area is larger, and can display more complete and eye-catching content, and can produce stronger visual impact, so as to better attract people's attention and achieve good advertising effects. It is deeply loved by manufacturers. However, this type of curtain wall is larger in size than ordinary curtain walls, so it is very difficult to transport. In addition, when changing the advertising content, it is necessary to dismantle the entire curtain wall and then install a new curtain wall. The operation is more troublesome, so it is difficult to use on a large scale.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a modular curtain wall and a method for using the same. Summary of the invention

[0015] The method for using the above-mentioned combined curtain wall comprises the following steps: Step 1: insert multiple wall panels into multiple limiting rods from the openings at the top of the frame in sequence for limiting, and the bottom of the wall panels is supported by the supporting plates, thereby forming a completed wall panel; Step 2: Push the lifting plate forward. The lifting plate drives the slider B forward through the L-shaped plate and the telescopic rod. The slider B slides forward along the guide rail B. When the slider B moves to the front of the guide rail B, the lifting plate is just opposite to the top of the wall panel. Step 3: Then push the lifting plate downward, and the telescopic rod shortens accordingly, thereby maintaining the linear movement of the lifting plate. The lifting plate moves downward so that the frame plate at the bottom is downwardly sleeved on the outer walls of multiple wall panels near the top. Then, rotate the circular top plate, and the circular top plate drives the threaded barrel to rotate, and the threaded barrel is installed on the screw rod. The threaded barrel also enters the through hole A. Finally, the circular top plate is close to the bottom surface of the circular groove, and finally the position of the lifting plate is fixed on the mounting plate, thus completing the fixation of multiple wall panels. Step 4: When the advertising surface needs to be replaced, first release the fixing component from the wall panel, and then push the wall panel backward, and the wall panel drives the slider A to move backward, and the slider A slides along the guide rail A, thereby moving the wall panel to the rotating space inside the frame; Step 5: Rotate the wall panel through the opening at the top of the frame (if it is inconvenient, you can use tools). The wall panel drives the rotation of the rotating rod through the limit rod, and the rotating rod drives the rotation of the inner ring of the bearing. The inner ring rotates along the outer ring. After the rotation is completed, push the wall panel forward and move the wall panel to the fixed position again for fixation.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention inserts a plurality of wall panels into a plurality of limiting rods from the opening at the top of the frame for limiting, and the bottom of the wall panel is supported by the supporting plate, thereby forming a completed wall panel. After that, the wall panel can be fixed by the fixing assembly, thereby completing the assembly of the modular curtain wall. In this way, the wall panel and the frame can be assembled separately, and the wall panel can be divided into multiple pieces, which is more convenient for transportation, thereby solving the problem of inconvenient transportation in the background technology; 2. The present invention can design different advertising contents on both sides of the wallboard. When the advertising contents need to be replaced, it is only necessary to release the fixing of the wallboard by the fixing assembly, and move the limit rod and the wallboard thereon to the rotating space through the flip assembly. After the rotation is completed, the limit rod is returned to the fixed position of the wallboard for fixing, and the wallboard can be flipped. By this method, each wallboard is flipped in turn, so that frequently used advertisements can be set on the front and back sides of the wallboard. The advertising slogans can be replaced without disassembling the entire curtain wall, which is more convenient for operation, so as to solve the problem in the background technology that when changing the advertising contents, the entire curtain wall needs to be disassembled and then a new curtain wall is installed, which is more troublesome to operate; 3. In the present invention, after the wall panel is turned over and before it moves to the fixed position, the square block will first move between the baffles, and the baffles will press against the two sides of the square block to restrict the square block and the wall panel to prevent rotation, which would otherwise be blocked by other wall panels and make it difficult to return to the fixed position.

[0019] Example 1 like Figures 1 to 3 As shown, the present invention provides a combined curtain wall, including a frame 1, and a wall panel 2 arranged inside the frame 1, the wall panel 2 is divided into a plurality of equal proportions, and can be installed one by one in the frame 1, a rotation space for the wall panel 2 is reserved in the middle of the frame 1, and the top of the frame 1 is open. The combined curtain wall also includes: The limiting structure 3 includes a plurality of support plates 301 arranged inside the frame 1, and through slots 302 provided on the wall panel 2 and penetrating the upper and lower ends thereof. The top ends of the support plates 301 are fixedly connected to limiting rods 303. The wall panel 2 is inserted into the limiting rods 303 through the through slots 302 thereon to limit the position. A fixing assembly 304 is also installed on the top of the frame 1 to fix the wall panel 2 in the frame 1. The flip assembly 4 can move the limiting rod 303 and the wall panel 2 thereon to move the wall panel 2 into the rotation space for rotation. After the rotation is completed, the wall panel 2 is returned to the fixed position to fix the wall panel 2.

[0020] When in use, multiple wall panels 2 are inserted into multiple limiting rods 303 from the openings at the top of the frame 1 in sequence for limiting, and the bottom of the wall panel is supported by the support plate 301, so as to form a complete wall panel 2 (the wall panels 2 are close to each other, thereby reducing the gap and improving the viewing integrity). After that, the wall panel 2 can be fixed by the fixing assembly 304 to complete the assembly of the modular curtain wall. In this way, the wall panel 2 and the frame 1 can be assembled separately, and the wall panel 2 can be divided into multiple pieces for more convenient transportation (the wall panel 2 is larger in size and more fragile than the frame during transportation, and is easily damaged by impact. If it is divided into multiple pieces for transportation, it can be reduced Low risk), and the present invention can design different advertising contents on both sides of the wall panel 2. When the advertising content needs to be replaced, it is only necessary to release the fixation of the wall panel 2 by the fixing component 304, and move the limit rod 303 and the wall panel 2 thereon to the rotation space through the flipping component 4. After the rotation is completed, return to the fixed position of the wall panel 2 for fixation, and the wall panel 2 can be flipped over (if it is not moved, the side ends of the wall panel 2 are tightly attached to each other and cannot be rotated). Through this method, each wall panel 2 is flipped over in turn, so that frequently used advertisements can be set on the front and back sides of the wall panel 2. The advertising slogans can be replaced without disassembling the entire curtain wall, which is more conducive to operation.

[0021] Furthermore, a protrusion 5 is provided near the bottom of the inner surface of the frame 1. The protrusion 5 is pressed against the surface of the wall panel 2 near the bottom, and the wall panel 2 just reaches the fixing position. The setting of the protrusion 5 facilitates the staff to find the fixing position of the wall panel 2, eliminating the alignment operation when the fixing component 304 is fixed.

[0022] It should be noted that the wall panel 2 can be set to a long strip with a square cross-section, so that different slogans can be designed on its four sides. By rotating and turning over (only two sides rotate 180 degrees, and the other four only need to rotate 90 degrees), four different types of advertisements can be presented to people, which is more effective.

[0023] In order to clearly show the structure in the attached drawings, the curtain wall is designed to be wider. If only the width is different from that in the present invention, it is still within the protection scope of the present invention.

[0024] Example 2 like Figures 1 to 7 As shown, this embodiment describes in detail the fixing assembly 304 and the turning assembly 4 in the embodiment 1: the fixing assembly 304 includes a guide rail A304a fixed on the inner surface of the top opening of the frame 1, the surface of the guide rail A304a is slidably connected to a slider A304b, the surface of the slider A304b is fixedly connected to a telescopic rod 304c, the head of the telescopic rod 304c is fixed to the lifting plate 304e through an L-shaped plate 304d, the bottom end of the lifting plate 304e is fixedly connected to a frame plate 304f, both sides of the inner surface of the frame 1 are fixedly connected to mounting plates 304g, the top four corners of the mounting plate 304g are fixedly connected to screws 304h, and the top four corners of the lifting plate 304e are provided with circular grooves 304g. 4i, a through hole A304j is provided at the bottom of the circular groove 304i, which passes through the bottom end of the mounting plate 304g and for the screw 304h to pass through, a threaded tube 304k is threadedly connected to the outer wall of the screw 304h, a circular top plate 304m is fixedly connected to the top of the threaded tube 304k, a sealing ring 304n is bonded to the bottom end of the circular top plate 304m, a screwdriver slot 304o is provided at the top of the circular top plate 304m, the flip assembly 4 is fixed to the guide rail B401 on the inner bottom wall of the frame 1 for the slider B402 to slide, a bearing 403 is fixedly connected to the top of the slider B402, a rotating rod 404 is fixedly connected to the inner ring of the bearing 403, and the top of the rotating rod 404 is connected to the bottom end of the support plate 301.

[0025] After the wall panel 2 is inserted into the limit rod 303 for limit, the fixation of the fixing assembly 304 can be released, and then the wall panel 2 can be pushed to move backward, and the wall panel 2 drives the slider A304b to move backward, and the slider A304b slides along the guide rail A304a, so as to move the wall panel 2 into the rotating space inside the frame 1, and the wall panel 2 is rotated through the opening at the top of the frame 1 (if it is inconvenient, tools can be used), and the wall panel 2 drives the rotation of the rotating rod 404 through the limit rod 303, and the rotating rod 44 drives the rotation of the inner ring of the bearing 403, and its inner ring rotates along its outer ring. After the rotation is completed, the wall panel 2 is pushed forward. Move the wall panel 2 to the fixed position again, and rotate each wall panel 2 in turn by this method, and then the completely turned over wall panel 2 can be fixed. When fixing, push the lifting plate 304e to move forward, and the lifting plate 304e drives the slider B402 to move forward through the L-shaped plate 304d and the telescopic rod 304c. The slider B402 slides forward along the guide rail B401. When the slider B402 moves to the front of the guide rail B401, the lifting plate 304e is just opposite to the top of the wall panel 2. Then, push the lifting plate 304e downward, and the telescopic rod 304c shortens accordingly, thereby maintaining the lifting plate 304e. 4e moves linearly, the lifting plate 304e moves downward so that the frame plate 304f at the bottom thereof is downwardly sleeved on the outer side walls of the plurality of wall panels 2 near the top end (closely attached to each other), and the bottom of the lifting plate 304e is close to the top end of the wall panel 2. At this time, the lifting plate 304e and the mounting plate 304g are close to each other. At this time, the through hole A304j on the lifting plate 304e is also inserted into the screw 304h of the mounting plate 304g, and then the circular top plate 304m is rotated (it should be noted that a screwdriver slot 304o is provided on the circular top plate 304m, and the circular top plate 304m can be rotated by acting on the screwdriver on the slot, which is more convenient for work The operator performs disassembly and assembly operations, and the circular top plate 304m can be disassembled by rotating it in the opposite direction). The circular top plate 304m drives the threaded barrel 304k to rotate, and the threaded barrel 304k is installed on the screw 304h. The threaded barrel 304k also enters the through hole A304j. Finally, the circular top plate 304m is close to the bottom surface of the circular groove 304i, and the sealing ring 304n thereon is squeezed, thereby sealing the connection part of the thread to prevent rust at this part, which makes it difficult to disassemble. Finally, the position of the lifting plate 304e is fixed on the mounting plate 304g, and the fixation of multiple wall panels is completed.

[0026] It should be noted that if the lifting plate 304e blocks the rotation or pushing of the wall panel 2 by the staff, the lifting plate 304e can be pushed back and forth to a position where it does not hinder the operation. Furthermore, a square block 405 is fixedly connected between the rotating rod 404 and the supporting plate 301, and a baffle 406 for limiting the rotation of the square block 405 is also fixedly connected to the inner surface of the protrusion 5, so that after the wall panel 2 is turned over, before moving to the fixed position, the square block 405 will first move between the baffles 406, and the baffles 406 will press against both sides of the square block 405 to limit the square block 405 and the wall panel 2 to prevent rotation, which will be blocked by other wall panels 2 and difficult to return to the fixed position.

[0027] Example 3 like Figure 4 , Figure 5 As shown, this embodiment is improved on the basis of embodiment 1. The frame 1 can be used in areas with normal climate. However, if it is used in areas that often encounter severe weather conditions such as strong winds, it is necessary to strengthen the stability of the structure. Therefore, in this embodiment, a fork-shaped reinforcement rod 6 is detachably connected to the rear part of the rotating space inside the frame 1, which can be installed as needed to avoid damage to the curtain wall. The following is a detachable structure: vertical plates 7 are fixedly connected to the upper and lower sides of both sides of the interior of the frame 1, and the four ends of the fork-shaped reinforcement rod 6 are fixedly connected to connecting blocks. Through holes B9 are provided on the connecting plates 8 and the vertical plates 7. The two through holes B9 are aligned and fixed by bolts. The fork-shaped reinforcement rod 6 can be installed. The frame 1 structure is reinforced by the fork-shaped reinforcement rod 6, which can better protect the curtain wall. Of course, it is not necessary to install it in areas with normal climate to reduce the cost of use.

[0028] The present invention also provides a method for using the combined curtain wall: Step 1: insert multiple wall panels 2 into multiple limiting rods 303 from the opening at the top of the frame 1 in sequence for limiting (the limiting rods 303 are in a fixed position in the initial state), and the bottom of the wall panel is supported by the support plate 301, thereby forming a completed wall panel 2; Step 2: Push the lifting plate 304e forward. The lifting plate 304e drives the slider B402 forward through the L-shaped plate 304d and the telescopic rod 304c. The slider B402 slides forward along the guide rail B401. When the slider B402 moves to the front of the guide rail B401, the lifting plate 304e is just opposite to the top of the wall panel 2. Step 3: Then push the lifting plate 304e downward, and the telescopic rod 304c shortens accordingly, thereby maintaining the linear movement of the lifting plate 304e. The lifting plate 304e moves downward so that the frame plate 304f at the bottom thereof is downwardly sleeved on the outer wall of the plurality of wall panels 2 near the top end. Then, the circular top plate 304m is rotated, and the circular top plate 304m drives the threaded cylinder 304k to rotate, and the threaded cylinder 304k is installed on the screw rod 304h. The threaded cylinder 304k also enters the through hole A304j. Finally, the circular top plate 304m is pressed against the bottom surface of the circular groove 304i, and finally the position of the lifting plate 304e is fixed on the mounting plate 304g, thus completing the fixing of the plurality of wall panels. Step 4: When the advertising surface needs to be replaced, first release the fixing component 304 from the wall panel, and then push the wall panel 2 to move backward, and the wall panel 2 drives the slider A304b to move backward, and the slider A304b slides along the guide rail A304a, so as to move the wall panel 2 to the rotation space inside the frame 1; Step 5: Rotate the wall panel 2 through the opening at the top of the frame 1 (if it is inconvenient, you can use tools). The wall panel 2 drives the rotation of the rotating rod 404 through the limit rod 303. The rotating rod 44 drives the rotation of the inner ring of the bearing 403, and its inner ring rotates along its outer ring. After the rotation is completed, push the wall panel 2 forward and move the wall panel 2 to the fixed position again for fixation.

[0029] A combined curtain wall and a method of using the same of the present invention have the following advantages: Insert multiple wall panels 2 from the opening at the top of the frame 1 into the multiple limiting rods 303 for limiting, and the bottom of the wall panel 2 is supported by the support plate 301, so as to form a completed wall panel 2. After that, the wall panel 2 can be fixed by the fixing assembly 304, so as to complete the assembly of the modular curtain wall. In this way, the wall panel 2 and the frame 1 can be assembled separately, and the wall panel 2 can be divided into multiple pieces, which is more convenient for transportation; Different advertising contents can be designed on both sides of the wall panel 2. When the advertising contents need to be changed, it is only necessary to release the fixing component 304 on the wall panel 2, and move the limit rod 303 and the wall panel 2 thereon to the rotating space through the flipping component 4. After the rotation is completed, the limit rod 303 and the wall panel 2 thereon are returned to the fixed position of the wall panel 2 for fixing, so that the wall panel 2 can be flipped. By this method, each wall panel 2 is flipped in turn, so that frequently used advertisements can be set on the front and back sides of the wall panel 2. The advertising slogans can be changed without disassembling the entire curtain wall, which is more convenient for operation. After the wall panel 2 is turned over and before it moves to the fixed position, the square block 405 will first move between the baffles 406, with the baffles 406 pressing against both sides of the square block 405 to restrict the square block 405 and the wall panel 2 to prevent rotation, which would otherwise be blocked by other wall panels 2 and make it difficult to return to the fixed position.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.

7. The combined curtain wall according to claim 5, characterized in that: A fork-shaped reinforcement rod (6) is detachably connected to the rear portion of the rotating space inside the frame (1).

8. The combined curtain wall according to claim 7, characterized in that: Vertical plates (7) are fixedly connected to the upper and lower sides of both sides of the frame (1), and connecting blocks (8) are fixedly connected to the four ends of the fork-shaped reinforcing rod (6). Through holes B (9) are provided on the connecting plates (8) and the vertical plates (7), and the two are fixed by bolts.

9. The combined curtain wall according to claim 1, characterized in that: The cross section of the wall panel (2) is square.

10. The method for using the combined curtain wall according to any one of claims 1 to 9, characterized in that: The steps include: Step 1: inserting a plurality of wall panels (2) from the opening at the top of the frame (1) into a plurality of limiting rods (303) in sequence for limiting, and the bottom of the wall panel (2) is supported by the supporting plate (301), thereby forming a completed wall panel (2); Step 2: Push the lifting plate (304e) to move forward. The lifting plate (304e) drives the slider B (402) to move forward via the L-shaped plate (304d) and the telescopic rod (304c). The slider B (402) slides forward along the guide rail B (401). When the slider B (402) moves to the frontmost part of the guide rail B (401), the lifting plate (304e) is exactly opposite to the top of the wall panel (2). Step 3: Then, the lifting plate (304e) is pushed downward, and the telescopic rod (304c) is shortened accordingly, thereby maintaining the linear movement of the lifting plate (304e). The lifting plate (304e) is moved downward so that the frame plate (304f) at the bottom thereof is downwardly sleeved on the outer wall of the plurality of wall panels (2) near the top. Then, the circular top plate (304m) is rotated, and the circular top plate (304m) drives the threaded cylinder (304k) to rotate, and the threaded cylinder (304k) is installed on the screw rod (304h). The threaded cylinder (304k) also enters the through hole A (304j). Finally, the circular top plate (304m) is pressed against the bottom surface of the circular groove (304i), and finally the position of the lifting plate (304e) is fixed on the mounting plate (304g), thereby completing the fixation of the plurality of wall panels (2); Step 4: When the advertising surface needs to be replaced, first release the fixing assembly (304) on the wall panel (2), and then push the wall panel (2) to move backward, and the wall panel (2) drives the slider A (304b) to move backward, and the slider A (304b) slides along the guide rail A (304a), thereby moving the wall panel (2) to the rotation space inside the frame (1); Step 5: Rotate the wall panel (2) through the opening at the top of the frame (1) (if it is inconvenient, use a tool). The wall panel (2) drives the rotating rod (404) to rotate through the limit rod (303). The rotating rod (404) drives the inner ring of the bearing (403) to rotate. The inner ring rotates along the outer ring. After the rotation is completed, the wall panel (2) is pushed forward and moved to the fixed position again for fixation.
