Description

Technical Field

[0001] This invention relates to the field of wall panel assembly technology, and more specifically to a wall system that allows for rapid installation or replacement. Background Technology

[0002] Lightweight panels such as honeycomb panels and foamed composite panels are widely used in building interior and exterior decoration projects due to their excellent thermal and sound insulation properties, as well as their light weight and high strength. These lightweight panels are usually laid on the surface of walls, which can improve the thermal and sound insulation effect of the walls and also achieve the function of decoration and aesthetics. At present, the installation method of lightweight panels on walls mostly uses metal keel as a supporting frame. First, the keel is fixed to the wall with expansion bolts, then the panels are attached to the surface of the keel, and the panels are locked to the keel with self-tapping screws or rivets. This installation method requires a lot of drilling, tapping and tightening work on site. Not only are the construction procedures numerous and labor-intensive, but the installation efficiency is also extremely low, which is difficult to meet the progress requirements of modern prefabricated construction. In addition, when it is necessary to replace or repair a panel, all the screws fixing the panel must be removed one by one. The disassembly process can easily damage the edges of the panel and the surface of the keel, making the panel unusable and increasing the cost and difficulty of later maintenance. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to propose a wall system that can be quickly installed or replaced in order to solve the problems mentioned in the background section above.

[0004] This invention is achieved through the following technical solution: A quick-install or replaceable wall system includes a first profile and a second profile, the first profile being fixed to a wall, the first profile having a first groove extending in a first direction, and the second profile being inserted into the first groove in the first direction. The second profile is formed with a plurality of left sliding grooves and a plurality of right sliding grooves extending along a second direction. The bottom of the left sliding groove is formed with a left inclined surface, and the bottom of the right sliding groove is formed with a right inclined surface. The left inclined surface slopes from the side away from the right inclined surface toward the side closer to the right inclined surface in a direction toward the wall, and the right inclined surface slopes from the side away from the left inclined surface toward the side closer to the left inclined surface in a direction toward the wall. It also includes a left irregular part inserted into the left slide groove, a right irregular part inserted into the right slide groove, and a slot formed by the adjacent left irregular part and the right irregular part; It also includes a wall panel, which is provided with a hook profile that is inserted into the slot.

[0005] Furthermore, the left irregular part is integrally formed with a first flat support portion, a first deformation portion vertically connected to the first flat support portion, and a first bending portion connected to the first deformation portion; the first bending portion includes a first right arc-shaped inclined arm, a first upper left inclined arm, a first lower left inclined arm, and a first lower right inclined hook connected in sequence. The right-shaped part is integrally formed with a second flat support, a second deformation part vertically connected to the second flat support, and a second bending part connected to the second deformation part; the second bending part includes a second left arc-shaped inclined arm, a second upper right inclined arm, a second lower right inclined arm and a second lower left inclined hook connected in sequence. In the same group, the first deformed portion, the first right arc-shaped arm, the second deformed portion, and the second left arc-shaped arm of the adjacent left and right irregular parts together form the slot.

[0006] Furthermore, the hook profile includes a left hook profile and a right hook profile. The left hook profile is provided with a left barb, and the right hook profile is provided with a right barb. When two adjacent wall panels are tightly spliced ​​together, the left barb and the right barb of the two wall panels are inserted into the same slot.

[0007] Furthermore, the rear end face of the wall panel abuts against the junction of the first upper left oblique arm and the first lower left oblique arm of the left irregular part, and simultaneously abuts against the junction of the second upper right oblique arm and the second lower right oblique arm of the right irregular part.

[0008] Furthermore, the first profile has a first support portion at both the upper and lower ends, the upper and lower ends of the first profile are embedded in the first support portion, the first support portion has a first anti-detachment portion extending to the front end of the first profile, and the first anti-detachment portion extends to the upper and lower ends of the left and right irregular parts. The second profile is provided with a second support portion, which is located at the left and right ends of the left and right irregular parts. The second support portion is provided with a second anti-detachment portion extending to the front end of the first flat support portion and the second flat support portion.

[0009] Furthermore, it also includes a number of connectors fixed to the wall by expansion screws and spaced apart along the height direction, and C-shaped profiles hanging on the connectors. The first profile is connected to the C-shaped profile by only a single countersunk screw, and the countersunk screw is centrally located on the first profile.

[0010] Furthermore, the C-shaped profile located at the highest position of the wall is connected to a supporting corner bracket, and the hook profile of the wall panel located at the highest position is hung on the upper end of the supporting corner bracket.

[0011] Furthermore, the second profile has several raised strips along the first direction at the bottom of the first groove.

[0012] Furthermore, the tilt angle of the tilted surface is 4.6°±2°.

[0013] Furthermore, the second profile is slidably connected to the first profile along the first direction, where the first direction is horizontal and the second direction is vertical.

[0014] The beneficial effects of this invention are as follows: Firstly, due to the presence of the left and right inclined planes, the external force is guided by these planes and transformed into a clamping force that brings the left and right irregular-shaped parts closer together. More importantly, because of the left and right inclined planes, the left and right irregular-shaped parts only need basic structural rigidity to lock the hook profile without relying on the elasticity of the materials themselves. This fundamentally avoids the inherent defects of traditional elastic buckles, such as elasticity attenuation or failure due to long-term use. Simultaneously, the connections between the components are non-rigid, allowing for relative movement. When subjected to thermal expansion and contraction, human pulling, or accidental impact vibrations, it can adaptively absorb external forces and alleviate internal thermal stress, avoiding stress concentration, structural damage, or wall panel deformation caused by rigid fixing. This significantly improves the long-term stability and environmental adaptability of the system.

[0015] Secondly, the wall panels are directly inserted into the slots along the vertical wall using hook profiles. This eliminates the need for upward lifting, overcoming ceiling height limitations, and allowing the top edge of the wall panel to approach the ceiling. Furthermore, there is no need for horizontal movement, eliminating the problem of end panels not being able to be joined, and the left and right edges of the wall panels can approach adjacent walls. No additional installation space is required in any direction, resulting in minimal gaps around the wall panels after installation, leading to a more aesthetically pleasing and neat overall appearance.

[0016] Thirdly, the functional components required by this system are only five basic profiles: the first profile, the second profile, the left irregular part, the right irregular part, and the hook profile. The left and right irregular parts have completely identical structures and can be produced using a unified mold, differing only in their orientation within the system. When installed in the left slide, the profile functions as a left irregular part; when installed in the right slide, it functions as a right irregular part, and the two are mirror images of each other. This system requires no additional small parts such as springs, washers, or latches. Each profile can be mass-produced using extrusion molding, resulting in fewer molds, lower production costs, and eliminating the need for on-site allocation of various loose parts. This simplifies material management and installation processes, reducing installation errors caused by numerous parts and the difficulty of replacing parts during later maintenance.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of aiding understanding the present invention, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] Reference Figures 1 to 6 As shown, a quick-install or replaceable wall system includes a first profile 1 fixed to and connected to the wall, a second profile 2 that slides with the first profile 1, a left profile 3 and a right profile 4 installed on the second profile 2, and a wall panel 6 with a hook profile.

[0026] The first profile 1 is fixed to the building wall by connectors 7. Specifically, several connectors 7 arranged at intervals along the height direction are first fixed to the wall by expansion screws 71. The connectors 7 are arranged in a horizontal direction. Then, the C-profile 8 is hung on the connectors 7.

[0027] The first profile 1 is connected to the C-profile 8 by a single countersunk screw 14, which is centrally located on the first profile 1. Due to this single-point connection with a centrally located screw, when the connector 7 or the C-profile 8 is slightly tilted due to unevenness of the wall surface or installation errors, the first profile 1 can freely swing around the countersunk screw 14 without being forced to follow the tilt direction of the connector 7 or the C-profile 8. This prevents the first profile 1 from tilting, avoids overall tilting of the wall panel 6 after installation, reduces the impact of wall base construction deviations on the installation accuracy of the wall panel 6, and improves the system's tolerance to installation errors.

[0028] The first profile 1 has a first groove 11 extending in a first direction, which is horizontal. The second profile 2 is inserted into the first groove 11 in a horizontal direction, achieving a sliding fit between the first profile 1 and the second profile 2. This fit allows the second profile 2 to slide horizontally within the first profile 1, thereby adjusting the left and right positions of the wall panels 6 and ensuring that the wall panels 6 in the left and right positions can be tightly joined. The second profile 2 has several raised strips 111 at the bottom of the first groove 11 in a horizontal direction. These raised strips 111 reduce the contact area between the second profile 2 and the first groove 11, thus reducing sliding resistance.

[0029] The second profile 2 has a plurality of left sliding grooves 21 and a plurality of right sliding grooves 22 extending along a second direction, which is a vertical direction. The left profile 3 and the right profile 4 have completely identical structures and can be produced using a unified mold, differing only in their orientation when installed in the system. When the profile is installed in the left sliding groove 21, it serves as the left profile 3, and when installed in the right sliding groove 22, it serves as the right profile 4. The left profile 3 and the right profile 4 are mirror images of each other.

[0030] The left irregular part 3 is integrally formed with a first flat support portion 31, a first deformation portion 32 vertically connected to the first flat support portion 31, and a first bending portion 33 connected to the first deformation portion 32. The first bending portion 33 includes a first right arc-shaped inclined arm 331, a first upper left inclined arm 332, a first lower left inclined arm 333, and a first lower right inclined hook 334 connected in sequence. The right irregular part 4 is integrally formed with a second flat support portion 41, a second deformation portion 42 vertically connected to the second flat support portion 41, and a second bending portion 43 connected to the second deformation portion 42. The second bending portion 43 includes a second left arc-shaped inclined arm 431, a second upper right inclined arm 432, a second lower right inclined arm 433, and a second lower left inclined hook 434 connected in sequence. Both the left irregular part 3 and the right irregular part 4 are made of metal, such as aluminum alloy, and have a certain degree of elasticity to ensure that they can deform appropriately under stress. The lengths of the left irregular part 3 and the right irregular part 4 are preferably 4 cm to 6 cm to maintain the straightness of each part.

[0031] Each second profile 2 is equipped with two left irregular parts 3 and two right irregular parts 4, arranged from left to right as left irregular part 3, right irregular part 4, left irregular part 3, right irregular part 4. The left irregular parts 3 and right irregular parts 4 located on the left and right sides cooperate to form the same group, while the right irregular part 4 located in the middle cooperates with the adjacent left irregular part 3 to form a different group. In the same group, the first deformation part 32, the first right arc-shaped arm 331, the second deformation part 42, and the second left arc-shaped arm 431 of the adjacent left irregular parts 3 and right irregular parts 4 together form a slot 5, into which the hook profile is inserted. In different groups, the transition part of the second right lower arc-shaped arm 433 and the second left lower arc-shaped hook 434 of the adjacent right irregular part 4 and left irregular part 3 abuts against the transition part of the first left lower arc-shaped arm 333 and the first right lower arc-shaped hook 334. The contact of the transition part enables the four irregular parts to form a mechanical linkage in the horizontal direction. When any one of the irregular parts is subjected to an external force, the external force is transmitted to the adjacent irregular parts in sequence through the transition part, so that the remaining irregular parts are subjected to force synchronously. The clamping force distribution at the slot 5 tends to be balanced, avoiding local tilting of the wall panel 6 and ensuring the stability of the wall panel 6.

[0032] The bottom of the left slide 21 has a left inclined surface 211, and the bottom of the right slide 22 has a right inclined surface 221. The left inclined surface 211 slopes from the side away from the right inclined surface 221 toward the side closer to the right inclined surface 221 in a direction toward the wall. The right inclined surface 221 slopes from the side away from the left inclined surface 211 toward the side closer to the left inclined surface 211 in a direction toward the wall.

[0033] Due to the directional arrangement of the left inclined plane 211 and the right inclined plane 221, the external force acting on the wall panel 6 is transformed into a clamping force that further brings the left irregular part 3 and the right irregular part 4 closer together. This clamping force prevents the hook profile from disengaging from the slot 5.

[0034] The arrangement of the left inclined plane 211 and the right inclined plane 221 has the following beneficial effects: Firstly, traditional snap-fit ​​connections rely on the elastic deformation of the material itself to generate clamping force. Over long-term use, material creep or elasticity decay can lead to a decrease in clamping force or even failure. In this application, due to the presence of the left inclined plane 211 and the right inclined plane 221, the left irregular part 3 and the right irregular part 4 only need to possess basic structural rigidity, without relying on the material's inherent elasticity to achieve the locking function. The locking force originates from the mechanical transformation of external force through the inclined planes, rather than the material's elastic restoring force. Therefore, there is no problem of elasticity decay or failure due to long-term use, greatly improving the long-term reliability and durability of the system.

[0035] Secondly, the left inclined surface 211 and the right inclined surface 221 make the various components non-rigid connections. When subjected to thermal expansion and contraction, human pulling of the wall panel 6, or accidental impact vibration, the left irregular part 3 can move in the left slide groove 21 and the right irregular part 4 can move in the right slide groove 22. This can adaptively absorb external forces and alleviate internal thermal stress, avoiding stress concentration, structural damage, or deformation of the wall panel 6 caused by rigid fixing, and significantly improving the long-term stability and environmental adaptability of the system.

[0036] Preferably, the inclination angles of the left inclined plane 211 and the right inclined plane 221 are 4.6°±2°. If the inclination angle is too large, when the external force is decomposed along the inclined plane, the component force perpendicular to the inclined plane decreases, while the component force along the inclined plane increases, resulting in an excessive lateral clamping force. On the one hand, this will cause the left irregular part 3 and the right irregular part 4 to excessively compress the hook profile, increasing the resistance during insertion and seriously affecting the smoothness of installation; on the other hand, under long-term excessive compression, the deformed part of the irregular part may produce excessive elastic deformation or even plastic deformation, leading to premature fatigue failure of the irregular part and reducing the service life and safety of the entire system. If the inclination angle is too small, when the external force is decomposed along the inclined plane, the lateral clamping force is insufficient and cannot provide enough clamping force to reliably lock the hook profile. The hook profile is prone to overcoming the clamping force and coming out of the slot 5, leading to a safety accident of the wall panel 6 falling off.

[0037] The first profile 1 has a first support portion 12 at both its upper and lower ends, which is embedded in the first support portion 12. The first support portion 12 has a first anti-detachment portion 13 extending to the front end of the first profile 1. The first anti-detachment portion 13 extends to the upper and lower ends of the left irregular part 3 and the right irregular part 4. The second profile 2 has a second support portion 23 at both ends of the left irregular part 3 and the right irregular part 4. The second support portion 23 has a second anti-detachment portion 24 extending to the front end of the first flat support portion 31 and the second flat support portion 41.

[0038] Through the above structure, the first anti-detachment part 13 blocks the first profile 1 and the second profile 2 from the direction perpendicular to the wall, preventing the second profile 2 from coming out of the first groove 11 of the first profile 1 in the direction perpendicular to the wall when subjected to an external force away from the wall. On the other hand, the first anti-detachment part 13 extends to the upper and lower ends of the irregular part, limiting the vertical displacement of the left irregular part 3 and the right irregular part 4, preventing the irregular part from moving up and down along the groove under the action of gravity or vibration. The second anti-detachment part 24 blocks the left irregular part 3 and the right irregular part 4 from the direction perpendicular to the wall, preventing the irregular parts from coming out of the groove in the direction perpendicular to the wall when subjected to external forces away from the wall (such as the outward pushing force applied to the irregular parts when the hook profile is pulled outward). On the other hand, the second anti-detachment part 24 is located at the left and right ends of the irregular parts, limiting the horizontal displacement of the left irregular part 3 and the right irregular part 4, preventing the irregular parts from sliding left and right in the groove due to installation deviation or external force, ensuring that the position of the groove 5 between adjacent left irregular parts 3 and right irregular parts 4 in the same group is accurate and stable, and avoiding the hook profile from failing to accurately engage or lock due to the movement of the irregular parts.

[0039] In summary, the first anti-detachment part 13 and the second anti-detachment part 24 cooperate with each other to form multi-dimensional limiting for the left irregular part 3 and the right irregular part 4 in the vertical and horizontal directions, respectively, to prevent the irregular parts from being displaced due to vibration, external force and other factors during long-term use, thereby ensuring the alignment accuracy and locking reliability of the slot 5 and the hook profile.

[0040] Wall panel 6 can be made of lightweight materials such as honeycomb panels or foamed composite panels. The hook profiles are installed in sections along the aluminum sheet folded edge seam on the side of wall panel 6. This folded edge seam serves as a positioning groove, ensuring that each section of the hook profile is on the same vertical line, guaranteeing even stress distribution after wall panel 6 is installed. The hook profiles include a left hook profile 61 and a right hook profile 62, respectively located on the left and right sides of wall panel 6. The left hook profile 61 has a left barb 611, and the right hook profile 62 has a right barb 621.

[0041] The wall panel 6 of this invention is mainly used in indoor spaces. During installation, the hook profile of the wall panel 6 is aligned with the groove 5 formed by the same set of left and right irregular parts 3 and 4. The wall panel 6 is then pushed directly against the wall in a direction perpendicular to the wall surface, and the hook profile is inserted into the groove 5. Due to the vertical wall insertion installation method, the wall panel 6 does not need to be lifted upwards (not limited by the height of the ceiling space) nor does it need to be inserted horizontally (there is no problem of the end wall panel 6 not being able to be spliced). The upper edge of the wall panel 6 can be installed close to the ceiling, and the left and right edges can be installed close to the adjacent wall. No additional operating space needs to be reserved in any direction. After installation, the gaps between the wall panel 6 and the boundary are minimal, resulting in a more beautiful and neat overall visual effect.

[0042] When two adjacent wall panels 6 are tightly joined, the right hook profile 62 of the left wall panel 6 and the left hook profile 61 of the right wall panel 6 are simultaneously inserted into the same slot 5, meaning that the same slot 5 simultaneously accommodates the hook profiles of two adjacent wall panels 6. The rear end face of the wall panel 6 abuts against the junction of the first upper left inclined arm 332 and the first lower left inclined arm 333 of the left irregular part 3, and simultaneously abuts against the junction of the second upper right inclined arm 432 and the second lower right inclined arm 433 of the right irregular part 4, thereby achieving support and positioning of the rear end face of the wall panel 6.

[0043] After each wall panel 6 is inserted sequentially along the vertical direction of the wall, they are stacked vertically. The top of the highest wall panel 6 is unrestrained and tends to flip outwards and detach, using its bottom as a fulcrum. Therefore, a supporting bracket 9 is connected to the C-shaped profile 8 at the highest position of the wall. The supporting bracket 9 is bolted to the C-shaped profile 8, and the upper end of the hook profile of the highest wall panel 6 hangs on the upper end of the supporting bracket 9. The supporting bracket 9 provides upper support for the hook profile of the highest wall panel 6, forming a constraint in the horizontal direction. When the wall panel 6 is subjected to wind pressure and tends to flip outwards, the upper end of the hook profile abuts against the supporting bracket 9, thereby preventing the highest wall panel 6 from flipping outwards and detaching.

[0044] The installation method for this wall system is as follows: First, fix several connectors 7 arranged at intervals along the height direction on the wall with expansion screws 71, and hang the C-shaped profile 8 on the connectors 7.

[0045] Then, the first profile 1 is connected to the C-profile 8 using a single countersunk screw 14, with the countersunk screw 14 centrally positioned in the first profile 1. The second profile 2 is inserted horizontally into the first groove 11 of the first profile 1. A limiting member is installed at the end of the first groove 11 to prevent the second profile 2 from accidentally slipping out. If the left and right position of the wall panel 6 needs to be adjusted, the second profile 2 can be pushed and slid in the first groove 11 to the desired position; if the front and back position of the wall panel 6 needs to be finely adjusted, the position of the second profile 2 relative to the first profile 1 in the direction perpendicular to the wall surface can be adjusted using an adjusting member.

[0046] Next, the left irregular part 3 and the right irregular part 4 are inserted into the left slide groove 21 and the right slide groove 22 respectively, and arranged alternately in the order of left irregular part 3, right irregular part 4, left irregular part 3, and right irregular part 4.

[0047] Finally, align the hook profile of wall panel 6 with the slot 5 formed by the left irregular part 3 and the right irregular part 4, and push wall panel 6 towards the wall in a direction perpendicular to the wall surface, so that the hook profile engages in the slot 5. Because wall panel 6 engages in a direction perpendicular to the wall surface, the upper edge of wall panel 6 can be installed close to the ceiling, and the left and right edges can be installed close to the adjacent wall. No additional operating space is required in any direction. After installation, the gaps between the wall panel 6 and the boundary are minimal, resulting in a beautiful and neat overall visual effect. For the highest wall panel 6, hang the upper end of its hook profile on the upper end of the supporting bracket 9. The supporting bracket 9 is locked to the C-shaped profile 8 with bolts. When wall panel 6 is subjected to an external force away from the wall surface, the upper end of the hook profile abuts against the supporting bracket 9, preventing the highest wall panel 6 from flipping outward and detaching.

[0048] When disassembling wall panel 6, use the suction cup to attach wall panel 6, then pull wall panel 6 outwards along the direction perpendicular to the wall to disengage the hook profile from the slot 5. No fasteners need to be removed. Wall panel 6 can be reused multiple times, and there are no special requirements for the installation sequence. Wall panel 6 can be disassembled and installed independently in any position.
