Description

Technical Field

[0001] This utility model relates to the field of curtain wall panel technology, specifically to a magnetic hidden frame fixing device for quick-release installation of curtain wall panels. Background Technology

[0002] A curtain wall is a non-load-bearing exterior wall cladding for a building. It hangs like a curtain, hence the name. It is a lightweight, decorative wall structure commonly used in modern large and high-rise buildings. Composed of panels and a supporting structural system, it has a certain degree of displacement relative to the main structure or its own deformation capacity. It is an exterior building envelope or decorative structure that does not bear the load of the main structure. Curtain walls can be categorized by use as follows: architectural curtain walls, component-type architectural curtain walls, unitized curtain walls, glass curtain walls, stone curtain walls, metal panel curtain walls, all-glass curtain walls, or point-supported glass curtain walls, etc.

[0003] Existing patent document CN215519409U discloses a frameless glass curtain wall that is easy to assemble and disassemble. The protected claim includes a keel, with a groove on one outer wall of the keel, and a fixing plate slidably connected to the inner wall of the groove. A vertical beam is fixedly connected to one outer wall of the fixing plate, and horizontal beams are fixedly connected to both outer walls of the vertical beams. Fixing grooves are formed on both outer walls of the horizontal beams and both outer walls of the vertical beams. A glass panel is disposed between the inner walls of the opposite sides of the fixing grooves. Structural adhesive is bonded between the outer walls of the glass panel and the inner walls of the fixing grooves. Fixing mechanisms are provided at both ends of the outer walls of the keel. This invention improves the fixing effect of the glass panel, prevents friction between the glass curtain wall and the wall surface during transportation, thus preventing wear and tear on the glass curtain wall. It facilitates regular cleaning and maintenance of the glass curtain wall, thereby extending its service life, and allows for cooling of the glass curtain wall in hot weather.

[0004] However, the aforementioned open-source, easily disassembled frameless glass curtain walls primarily focus on improving the fixing effect of the glass panels, preventing friction between the glass curtain wall and the wall surface during transportation, thus avoiding wear and tear on the glass curtain wall, facilitating regular cleaning and maintenance to extend the service life of the glass curtain wall, and providing cooling treatment for the glass curtain wall in hot weather. However, they do not consider that the installation method of fixing the glass panels with structural adhesive, and then using a suction cup to adhere the glass panels by moving the limit bolts and moving the support plate, is rather cumbersome and reduces the efficiency of panel disassembly and assembly for workers.

[0022] Please see Figure 1-3A quick-release magnetic concealed frame fixing device for curtain wall panels includes a keel 1 and a glass panel 2. A sub-frame 4 is provided on the glass panel 2. Multiple sets of mounting brackets 3 are provided on the keel 1. A positioning groove 5 is provided on the sub-frame 4, and a first magnetic suction element 6 is provided inside the positioning groove 5. Multiple positioning structures are provided on the keel 1, each positioning structure including a positioning block 9 that can cooperate with the positioning groove 5 and a second magnetic suction element 10 that can cooperate with the first magnetic suction element 6. The keel 1 is the main support structure of the curtain wall, fixed to the building structure, bearing the weight of the glass panel 2 and its associated structures, and transferring the load to the building structure. The glass panel 2 forms the exterior facade of the curtain wall, providing functions such as lighting, heat insulation, and sound insulation. The sub-frame 4 is a transition structure between the glass panel 2 and the keel 1, enhancing the rigidity of the panel and providing an installation positioning interface for installation. The support plate 3 supports the weight of the sub-frame 4, providing initial positioning and horizontal support for the panel. The positioning groove 5 cooperates with the positioning block 9 to achieve precise alignment during panel installation and limit horizontal displacement of the panel. The first magnetic suction piece 6 and the second magnetic suction piece 10 form a magnetic attraction pair, assisting the positioning block 9 in engaging the positioning groove 5 and enhancing connection stability. Through a dual fixing method of mechanical locking and magnetic attraction, based on the mechanical locking between the positioning block 9 and the positioning groove 5, the magnetic attraction pair formed by the first magnetic suction piece 6 and the second magnetic suction piece 10 enhances connection stability, effectively preventing the glass panel 2 from loosening or shifting during use, ensuring the safety of the glass curtain wall. Utilizing the magnetic principle and simple operation of the pull rod 11, the glass panel 2 can be quickly installed and disassembled, significantly shortening the operator's operation time and significantly improving the efficiency of panel installation and disassembly.

[0023] Please see Figure 2 and Figure 3The keel 1 is equipped with multiple sets of frames 7. Each frame 7 has a mounting bracket 8 that is movable at its upper limit. The mounting bracket 8 has a positioning block 9 that is movable at its internal limit. A second magnetic suction element 10 is located at the bottom of the positioning block 9. The mounting bracket 8 has multiple sets of guide rods 12. Each guide rod 12 has a connecting element 13 that is movable at its upper limit. The external part of the connecting element 13 is connected to the external part of the positioning block 9. The mounting bracket 8 has multiple sets of push springs 14 inside. One end of each spring 14 contacts the external part of the connecting element 13 and surrounds the external part of the guide rod 12. The frame 7, mounted on the keel 1, provides support and movement space for the mounting bracket 8, limiting its movement trajectory. The mounting bracket 8 serves as the movable carrier for the positioning block 9. The extension and retraction of the block is controlled by pushing the springs 14 and the magnetic suction element. The guide rods 12 guide the linear movement of the positioning block 9, ensuring its accurate insertion into the positioning slot 5. The connecting element 13 connects the positioning block 9 and the guide rods 12, transmitting the pushing force of the springs 14 and the pulling force of the pull rods 11. The spring 14 provides elastic thrust to ensure that the positioning block 9 remains locked during normal use. The positioning block 9 is limited in movement by the connector 13 and the guide rod 12, and is mechanically locked by inserting into the positioning groove 5. The second magnetic suction member 10 at the bottom enhances the connection force. The second magnetic suction member 10 is located at the bottom of the positioning block 9 and corresponds to the first magnetic suction member 6 in the positioning groove 5. It forms a magnetic attraction pair with the first magnetic suction member 6 to provide initial attraction force and ensure that the positioning block 9 and the positioning groove 5 are tightly connected.

[0024] Please see Figure 3 The mounting bracket 8 has a magnetic suction component 16 inside, and the top of the positioning block 9 has a magnetic suction component 2 15 that can cooperate with the magnetic suction component 16. The top of the positioning block 9 also has a pull rod 11, with one end of the pull rod 11 extending to the outside of the mounting bracket 8. One end of the pull rod 11 is fixed to the top of the positioning block 9, and the other end extends to the outside of the mounting bracket 8. When disassembling, the positioning block 9 is disengaged from the positioning groove 5 by pulling the pull rod 11, and is attracted to the magnetic suction component 16 by the magnetic suction component 2 15, thereby fixing the disengaged positioning block 9 and realizing quick unlocking.

[0025] Please see Figure 3 The frame 7 is provided with a magnetic suction component 3 17 that can cooperate with the second magnetic suction component 10. The magnetic suction component 3 17 cooperates with the second magnetic suction component 10 so that when the positioning block 9 stops positioning, the mounting frame 8 can be fixed to the frame 7 by the attraction between the magnetic suction component 3 17 and the second magnetic suction component 10.

[0026] Working principle: During installation, the glass panel 2 is installed to the outside of the keel 1 via the sub-frame 4 and the mounting plate 3. By moving the mounting bracket 8 on the frame 7, the positioning block 9 inside the mounting bracket 8 can be aligned with the positioning groove 5 on the sub-frame 4. As the pull rod 11 is pushed, the magnetic attraction component 2 15 and the magnetic attraction component 16 are released. The compressed push spring 14 pushes the positioning block 9 into the interior of the positioning groove 5. The first magnetic attraction component 6 and the second magnetic attraction component 10 at the bottom of the positioning block 9 attract each other due to magnetism, generating an attraction force. At this time, the positioning block 9 cooperates with the positioning groove 5 to restrict the horizontal displacement of the glass panel 2. The first magnetic attraction component 6 and the second magnetic attraction component 10 at the bottom of the positioning block 9 attract each other due to magnetism. The magnetic attraction formed by 0 further enhances the connection stability; during disassembly, pulling the pull rod 11 extending to the outside of the mounting bracket 8 causes the positioning block 9 to move upward and disengage from the positioning groove 5. When the positioning block 9 rises to a certain position, the magnetic attraction part 2 15 at the top of the positioning block 9 attracts the magnetic attraction part 16 inside the mounting bracket 8, fixing the positioning block 9 after it has disengaged from the positioning groove 5 and preventing it from falling back, thereby achieving quick unlocking; in addition, when the positioning block 9 stops positioning and moves back to the frame 7, the magnetic attraction part 3 17 on the frame 7 attracts the second magnetic attraction part 10 at the bottom of the positioning block 9, fixing the mounting bracket 8 together with the positioning block 9 to the frame 7, facilitating subsequent operations.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
