Description
Technical Field
[0001] This utility model relates to the field of prefabricated wall panel technology, specifically to a connection structure for a high-efficiency dry replaceable wall panel. Background Technology
[0002] Dry-hanging wall panels are a construction technique for exterior wall decoration, mainly used for the installation of materials such as stone, metal panels, and ceramic panels. Its core feature is that it does not rely on wet application of cement mortar, but instead uses a metal frame and hangers to suspend and fix the decorative panels to the building structure, forming a structure with a certain cavity between the panels and the wall.
[0003] In existing dry-hanging wall panel structures, welding or bolt fastening is usually used to achieve permanent connection between the wall panel and the wall. Although bolt and welding fastening structures can ensure the overall stability of the wall, they are difficult to disassemble. When a single wall panel is damaged, aged, or needs to be upgraded, the entire wall structure needs to be destructively removed, resulting in high maintenance costs. Utility Model Content
[0004] In view of this, the present invention provides a connection structure for a high-efficiency dry-mounted replaceable wall panel to solve the problem of high replacement and maintenance costs of dry-mounted wall panels in the prior art.
[0005] This utility model provides a connection structure for a high-efficiency dry replaceable wall panel, including:
[0006] The first mounting component has a snap-fit groove on one side and a first snap-fit part on the inner side of the snap-fit groove.
[0007] The second mounting component has a snap-fit protrusion fixedly mounted on one side, and a second snap-fit part is provided on the outer side wall of the snap-fit protrusion. An elastic reset component is installed between the first snap-fit part and the snap-fit groove or between the second snap-fit part and the snap-fit protrusion. The first snap-fit part is adapted to snap-fit with the second snap-fit part under the elastic force of the elastic reset component.
[0008] The first mounting component is adapted to be fixedly connected to one of the wall panel body or the external fixing structure, and the second mounting component is adapted to be fixedly connected to the other of the wall panel body or the external fixing structure.
[0009] Beneficial Effects: During installation, taking the wall panel body to a wall serving as an external fixing structure as an example, the wall panel mounting device achieves a secure connection between the first and second mounting components by engaging the snap-fit groove of the first mounting component and the snap-fit protrusion of the second mounting component. The inner side of the snap-fit groove of the first mounting component has a first snap-fit portion, which engages with a second snap-fit portion on the outer side wall of the snap-fit protrusion of the second mounting component. This engagement secures the first and second mounting components together. Simultaneously, an elastic reset component is installed between the first snap-fit portion and the snap-fit groove, or between the second snap-fit portion and the snap-fit protrusion. This elastic reset component utilizes its elastic properties to facilitate the disassembly of the first and second mounting components. The first and second mounting components are respectively connected to the wall panel body or the wall. During installation, the first or second mounting component, which is to be installed on the wall panel, is pushed in perpendicularly to the wall from the position where the snap-fit protrusion and snap-fit groove just intersect. The elastic reset component engages the first and second snap-fit parts, allowing the first snap-fit part to apply a resisting force to the snap-fit protrusion while simultaneously sliding into the second snap-fit part on the outer wall of the snap-fit protrusion, ultimately securing the wall panel and the wall. For disassembly, the wall panel body is pulled outwards perpendicular to the wall. By overcoming the elastic force of the elastic reset component, the snap-fit protrusion is pulled out of the snap-fit groove, thus separating the first and second mounting components. The high-efficiency dry replaceable wall panel connection structure of this utility model uses the interlocking groove of the first mounting part and the interlocking protrusion of the second mounting part to cooperate with each other, and utilizes the elastic force of the elastic reset part to automatically engage the first and second interlocking parts, realizing the fast and stable installation and disassembly of the wall panel. The installation process does not require additional tools, the installation operation is simple, and it can effectively improve the construction efficiency of wall panel installation and replacement, and reduce the maintenance cost after the wall panel is installed.
[0010] In one alternative embodiment, one of the first and second snap-fit portions is a snap-fit groove, and the other of the first and second snap-fit portions is a snap-fit protrusion, which is engaged with the elastic reset member.
[0011] Beneficial effects: By setting a snap-fit groove on the first or second snap-fit part and a snap-fit protrusion on the other corresponding part, and using an elastic reset component to make the two automatically snap together, the wall panel can be installed and disassembled without damage. The structure is simple and reliable. During installation, it can be locked by simply pushing it flat, which greatly improves the construction efficiency. At the same time, the elastic reset component enhances the stability and shock resistance of the connection, and is suitable for various wall panel installation scenarios.
[0012] In one alternative embodiment, an installation groove is provided on the inner side of the snap-fit groove or the outer side wall of the snap-fit protrusion. The installation groove is arranged perpendicular to the axial direction of the snap-fit protrusion. The elastic reset member is installed in the installation groove, and the snap-fit protrusion extends at least partially outside the installation groove.
[0013] Beneficial effects: By setting a mounting groove perpendicular to the axial direction on the snap-fit groove or snap-fit protrusion and embedding the elastic reset component inside it, while extending the snap-fit protrusion part outside the mounting groove, the concealed installation of the elastic reset component is achieved. This not only enhances the structural compactness but also ensures the stable elastic force during snap-fit, making the wall panel installation more secure and disassembly more convenient. At the same time, it avoids the wear risk of exposed elastic components, improving the overall service life and aesthetics.
[0014] In one alternative implementation, the snap-fit protrusion is a spherical protrusion, and the snap-fit groove is an arc-shaped groove.
[0015] Beneficial effects: By adopting the combination design of spherical protrusions and arc-shaped grooves, combined with the elastic force of the elastic reset component, the snap-fit process is smoother and the alignment is more precise. At the same time, the spherical contact surface can adaptively adjust the angle, effectively reducing friction loss during installation, enhancing seismic resistance and long-term stability, ensuring that the wall panel can maintain reliable connection strength after frequent disassembly and assembly, and improving construction efficiency and structural durability.
[0016] In one optional embodiment, at least one pair of first snap-fit portions are symmetrically arranged along the axial direction of the snap-fit protrusion, and the second snap-fit portions are arranged in a one-to-one correspondence with the first snap-fit portions.
[0017] Beneficial effects: By symmetrically arranging at least one pair of first snap-fit parts along the axial direction of the snap-fit protrusion and correspondingly setting a second snap-fit part, the wall panel is subjected to more uniform and balanced force during installation, effectively preventing skewing or loosening caused by unilateral force, improving the stability and load-bearing capacity of the connection structure, and is suitable for the needs of rapid prefabricated buildings.
[0018] In one alternative embodiment, the connection between the snap-fit protrusion and the snap-fit groove is provided with a rounded corner.
[0019] Beneficial effects: By setting a rounded corner structure at the connection between the snap-fit protrusion and the snap-fit groove, the frictional resistance during installation is significantly reduced, allowing the wall panel to slide into position more smoothly. At the same time, it avoids the stress concentration problem that may occur at right-angled edges, and improves the fatigue resistance and service life of the connection parts.
[0020] In one alternative implementation, the length of the snap-fit protrusion is not less than the depth of the snap-fit groove.
[0021] Beneficial effects: By ensuring that the length of the snap-fit protrusion is not less than the depth of the snap-fit groove, it is guaranteed that the two can form a full snap-fit when they are mated, thereby enhancing the stability of the connection; it effectively prevents the wall panel from loosening or falling off when under stress, while allowing the elastic reset component to fully exert its buffering and automatic alignment functions, thus improving the reliability and durability of the overall structure.
[0022] In one alternative implementation, the resilient reset element is a spring or a sheet spring.
[0023] Beneficial effects: By using springs or spring sheets as elastic reset components, not only is a stable and reliable elastic support force provided, ensuring that the snap-fit protrusion and snap-fit groove are tightly engaged, but the standardized design of springs or spring sheets also facilitates mass production and replacement. At the same time, it takes into account both structural strength and cost control, and is suitable for the rapid installation and long-term use needs of various building wall panels.
[0024] In one alternative embodiment, a buffer is mounted on the side of the first mounting member facing the second mounting member, and / or, a buffer is mounted on the side of the second mounting member facing the first mounting member.
[0025] Beneficial effects: By adding buffers to the mating surfaces of the first and / or second mounting components, the impact force during wall panel installation is effectively absorbed and the noise generated by rigid contact is reduced. At the same time, the buffers can compensate for installation tolerances and ensure a tight fit of the snap-fit structure. This not only improves the smoothness and sealing of wall panel installation, but also extends the service life of the connection parts through shock absorption. It is particularly suitable for prefabricated building scenarios with high requirements for sound insulation and seismic resistance. Attached Figure Description

[0035] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0036] Dry-hanging wall panels are a construction technique for exterior wall decoration, primarily used for installing high-end decorative materials such as stone, metal panels, and ceramic panels. A frame system is built onto the main building structure, and the decorative panels are mechanically suspended from the frame using specialized hangers, creating an air gap of a certain thickness between the panels and the building wall. This construction method completely eliminates the traditional wet-laying process with cement mortar, offering significant advantages such as superior seismic performance, high installation efficiency, and prevention of efflorescence. Through a scientifically designed load transfer path, the dry-hanging system can effectively withstand horizontal loads such as wind pressure and seismic forces, while ensuring the flatness and durability of the decorative layer.
[0037] Existing dry-hanging wall panel systems typically use permanent connections such as welding or high-strength bolts to fix the wall panels to the main structure. While this rigid connection system ensures the overall structural stability of the building's exterior walls, it reveals significant maintenance defects in actual use. When a single wall panel needs replacement due to external impact, material aging, or other reasons, the irreversible nature of the connection structure forces maintenance personnel to destructively remove adjacent wall panels and supporting structures. This maintenance method not only significantly increases labor and time costs but also generates a large amount of construction waste, seriously violating the concept of sustainable development in modern architecture. This defect of traditional dry-hanging systems is particularly pronounced in commercial buildings that require frequent updates to their facade functions.
[0038] The following is combined with Figure 1 and Figure 3 The following describes embodiments of the present invention.
[0039] According to an embodiment of the present invention, in one aspect, a connection structure for a high-efficiency dry replaceable wall panel is provided, comprising:
[0040] The first mounting member 101 has a snap-fit groove 102 on one side, and a first snap-fit portion 104 on the inner side of the snap-fit groove 102; the second mounting member 105 has a snap-fit protrusion 106 fixedly mounted on one side, and a second snap-fit portion 107 on the outer side wall of the snap-fit protrusion 106; an elastic reset member 103 is installed between the first snap-fit portion 104 and the snap-fit groove 102 or between the second snap-fit portion 107 and the snap-fit protrusion 106; the first snap-fit portion 104 is adapted to snap-fit with the second snap-fit portion 107 under the elastic force of the elastic reset member 103; the first mounting member 101 is adapted to be fixedly connected to one of the wall panel body 2 or the external fixing structure, and the second mounting member 105 is adapted to be fixedly connected to the other of the wall panel body 2 or the external fixing structure.
[0041] This utility model provides a high-efficiency dry-type replaceable wall panel connection structure 1, consisting of a first mounting component 101 and a second mounting component 105. A snap-fit mechanism enables rapid installation and disassembly of the wall panel and the wall 3. Specifically, the first mounting component 101 has a snap-fit groove 102 with a first snap-fit portion 104 on its inner wall, while the second mounting component 105 has a snap-fit protrusion 106 with a second snap-fit portion 107 on its outer wall. The two components are mechanically interlocked through the cooperation of the first snap-fit portion 104 and the second snap-fit portion 107. The elastic pre-tightening force generated by the elastic reset component 103 provided between the first snap-fit portion 104 and the snap-fit groove 102 or between the second snap-fit portion 107 and the snap-fit protrusion 106 ensures that the first snap-fit portion 104 can slide into the locking position of the second snap-fit portion 107 during installation, and also allows for non-destructive separation through elastic deformation during disassembly. During installation, only a pushing force needs to be applied to the wall panel in the direction perpendicular to the wall 3 to achieve precise snap-fit; during disassembly, force needs to be applied in the direction parallel to the wall 3. Compared to traditional bolt fixing methods, this method improves construction efficiency and is particularly suitable for installing wall panels in commercial spaces that require frequent replacement.
[0042] In this scheme, the first mounting component 101 is fixedly connected to the wall 3, and the second mounting component 105 is fixedly connected to the wall panel.
[0043] In some embodiments, combined with Figure 2 As shown, one of the first snap-fit portion 104 and the second snap-fit portion 107 is a snap-fit groove, and the other of the first snap-fit portion 104 and the second snap-fit portion 107 is a snap-fit protrusion. The snap-fit protrusion is engaged with the elastic reset member 103.
[0044] By providing a snap-fit groove on the first snap-fit part 104 or the second snap-fit part 107, and a snap-fit protrusion on the other corresponding part, and using the elastic reset member 103 to make the two automatically snap together, the wall panel can be installed and disassembled without damage. The structure is simple and reliable. During installation, it can be locked by simply pushing it flat, which greatly improves the construction efficiency. At the same time, the elastic reset member 103 enhances the stability and shock resistance of the connection, and is suitable for various wall panel installation scenarios.
[0045] In this design, the second snap-fit part 107 is preferably a snap-fit groove, and the first snap-fit part 104 is a snap-fit protrusion.
[0046] Furthermore, an installation groove is provided on the inner side of the snap-fit groove 102 or the outer side wall of the snap-fit protrusion 106. The installation groove is arranged perpendicular to the axial direction of the snap-fit protrusion 106. The elastic reset member 103 is installed in the installation groove, and the snap-fit protrusion extends at least partially outside the installation groove.
[0047] By setting a mounting groove perpendicular to the axial direction on the snap-fit groove 102 or the snap-fit protrusion 106, and embedding the elastic reset member 103 therein, while extending the snap-fit protrusion part outside the mounting groove, the concealed installation of the elastic reset member 103 is achieved. This not only enhances the structural compactness, but also ensures the stable elastic force during snap-fit, making the wall panel installation more secure and disassembly more convenient. At the same time, it avoids the wear risk of exposed elastic parts, and improves the overall service life and aesthetics.
[0048] Specifically, the snap-fit protrusion is a spherical protrusion, and the snap-fit groove is an arc-shaped groove. By adopting the matching design of the spherical protrusion and the arc-shaped groove, combined with the elastic force of the elastic reset component 103, the snap-fit process is smoother and the alignment is more precise. At the same time, the spherical contact surface can adaptively adjust the angle, effectively reducing friction loss during installation, enhancing seismic resistance and long-term stability, ensuring that the wall panel can maintain reliable connection strength after frequent disassembly and assembly, and improving construction efficiency and structural durability.
[0049] Specifically, the connection between the snap-fit protrusion 106 and the snap-fit groove 102 is provided with a rounded corner. By providing a rounded corner structure at the connection between the snap-fit protrusion 106 and the snap-fit groove 102, the frictional resistance during installation is significantly reduced, allowing the wall panel to slide into position more smoothly. At the same time, it avoids the stress concentration problem that may occur at right-angled edges, and improves the fatigue resistance and service life of the connection part.
[0050] It is worth noting that the length of the snap-fit protrusion 106 is not less than the depth of the snap-fit groove. By ensuring that the length of the snap-fit protrusion 106 is not less than the depth of the snap-fit groove, it is ensured that the two can form a full snap-fit when they are mated, thereby enhancing the stability of the connection; effectively preventing the wall panel from loosening or falling off under stress, while allowing the elastic reset member 103 to fully exert its buffering and automatic alignment functions, thus improving the reliability and durability of the overall structure.
[0051] It is worth noting that the elastic reset element 103 is a spring or a spring sheet. By using a spring or spring sheet as the elastic reset element 103, not only is a stable and reliable elastic support force provided, ensuring that the snap-fit protrusion and snap-fit groove are tightly engaged, but the standardized design of the spring or spring sheet also facilitates mass production and replacement. At the same time, it takes into account both structural strength and cost control, and is suitable for the rapid installation and long-term use needs of various building wall panels.
[0052] In some embodiments, combined with Figure 2 As shown, at least one pair of first snap-fit portions 104 are symmetrically arranged along the axial direction of snap-fit protrusions 106, and the second snap-fit portions 107 are arranged in a one-to-one correspondence with the first snap-fit portions 104.
[0053] By symmetrically arranging at least one pair of first snap-fit parts 104 along the axial direction of the snap-fit protrusion 106 and correspondingly providing second snap-fit parts 107, the wall panel is subjected to more uniform and balanced force during installation, effectively preventing skewing or loosening caused by unilateral force, improving the stability and load-bearing capacity of the connection structure, and is suitable for the needs of rapid prefabricated buildings.
[0054] In some embodiments, combined with Figure 2 As shown, a buffer is mounted on the side of the first mounting member 101 facing the second mounting member 105, and / or, a buffer is mounted on the side of the second mounting member 105 facing the first mounting member 101.
[0055] By adding buffers to the mating surfaces of the first mounting component 101 and / or the second mounting component 105, the impact force during wall panel installation is effectively absorbed and the noise generated by rigid contact is reduced. At the same time, the buffers can compensate for installation tolerances and ensure that the snap-fit structure fits tightly. This not only improves the smoothness and sealing of wall panel installation, but also extends the service life of the connection parts through shock absorption. It is particularly suitable for prefabricated building scenarios with high requirements for sound insulation and seismic resistance.
[0056] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation. Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the present invention.
