Abstract
Description
Technical Field
[0001] This utility model relates to the field of wall panel installation technology, specifically a connection structure between a thin metal wall panel and a wooden back panel. Background Technology
[0002] In contemporary architectural decoration and furniture manufacturing, composite structures combining thin metal sheets with wooden back panels are widely used due to their combination of aesthetics and functionality. Currently, the connections in this structure mainly rely on chemical adhesives or mechanical rigid connections such as screws and rivets. High-strength epoxy resin adhesives or expanding foam provide a continuous bonding surface, while screw connections achieve fixation through direct mechanical interlocking.
[0003] However, this rigid connection method, characterized by permanent fixation, has significant maintenance drawbacks. When it's necessary to replace or refurbish the metal finish, or inspect or repair the internal wooden substrate, the existing connection structure is almost impossible to disassemble without damage. Adhesive connections require forceful prying or sanding to remove, easily damaging both the expensive metal panels and the wooden substrate; while screw connections, after removal, not only leave permanent holes in the metal surface, but repeated screwing can also reduce the holding power of the wooden substrate, making reliable reconnection difficult. This greatly increases the cost and complexity of later maintenance, limiting the application of this structure in situations requiring regular updates or repairs.
[0004] Therefore, this utility model proposes a connection structure between a thin metal wall panel and a wooden back panel. Utility Model Content
[0005] The purpose of this utility model is to provide a connection structure between a thin metal wall panel and a wooden back panel, so as to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a connection structure between a thin metal wall panel and a wooden back panel, including a connecting box located between a wooden board and a metal panel, the side of the connecting box being fixedly connected to the wooden board, the cross-section of the connecting box being trapezoidal, a sliding plate being provided on the side of the connecting box, the sliding plate being located on the side of the metal panel and fixedly connected to it, the bottom sloping area of the sliding plate contacting the sloping area of the connecting box, and in this state, the metal panel and the wooden board are parallel to each other.
[0006] Preferably, the connector box has multiple insert rods inside, the bottom of each insert rod has a connecting rod, the bottom of each connecting rod has multiple springs, and the slide plate has slots for inserting the insert rods inside.
[0007] Preferably, under normal conditions, the spring force pushes the connecting rod to lift the insert rod and insert it into the slot.
[0008] Preferably, the wall of the connecting box is provided with multiple through holes, and the connecting rod is located on the other side of the through holes.
[0009] Preferably, the metal plate has a connecting block on one side, and the other side of the connecting block is fixedly connected to the wooden board. The connecting block is trapezoidal in shape.
[0010] Preferably, the connecting block itself is elastic.
[0011] This utility model has at least the following beneficial effects: In this invention, a connecting box is installed between the wooden board and the metal board. The side of the connecting box is fixedly connected to the wooden board, and its cross-section is trapezoidal. A sliding plate, which can slide freely and whose bottom sloping area contacts the sloping area of the connecting box, is located on the side of the metal board and fixedly connected to it. This achieves a parallel and relatively movable connection between the metal board and the wooden board. This design allows for easy separation of the metal board and the wooden board by sliding the sliding plate through multiple through holes in the connecting box wall when replacing or renovating the metal finish or inspecting and repairing the internal wooden base layer. This avoids the damage caused by adhesive or screw connections, reducing the cost and complexity of later maintenance. The trapezoidal elastic connecting block on the side of the metal board further enhances the stability and reliability of the connection. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-6 This utility model provides a technical solution: a connection structure between a thin metal panel and a wooden backing board for a wall surface, including a connecting box 1 located between a wooden board and a metal panel. The side of the connecting box 1 is fixedly connected to the wooden board, and the connecting box 1 is parallel to the ground. The cross-section of the connecting box 1 is trapezoidal, and a sliding plate 2 is provided on the side of the connecting box 1. The sliding plate 2 slides freely on the connecting box 1. The sliding plate 2 is located on the side of the metal panel and fixedly connected to it. The bottom sloping area of the sliding plate 2 is in contact with the sloping area of the connecting box 1. In this state, the metal panel and the wooden board are parallel to each other. The metal panel can slide freely on the side of the wooden board through the sliding relationship between the sliding plate 2 and the connecting box 1, which facilitates the installation of the metal panel by the workers. At the same time, the space reserved between the metal panel and the wooden board is conducive to the workers' inspection and replacement of the wooden backing board without the need for violent disassembly, effectively avoiding double damage to the metal panel and the wooden base layer.
[0016] The connecting box 1 contains multiple insert rods 3, which are slidably connected to the connecting box 1. A connecting rod 4 is fixedly connected to the bottom of each insert rod 3. Multiple springs 5 are located at the bottom of the connecting rod 4, with both ends of the springs 5 fixedly connected to the connecting rod 4 and the inner wall of the connecting box 1, respectively. The sliding plate 2 contains slots 6 for inserting the insert rods 3. Under normal conditions, the spring force of the springs 5 pushes the connecting rod 4, lifting the insert rod 3 into the slot 6, thus limiting the position of the metal plate on the wooden board. The wall of the connecting box 1 has multiple through holes 7. The connecting rod 4 is located on the other side of each through hole 7. During disassembly, workers can directly push the connecting rod 4 downwards through the through hole 7, allowing the insert rod 3 to slide out of the slot 6, facilitating subsequent removal of the metal plate.
[0017] In addition, a connecting block 8 is provided on the side of the metal plate. The other side of the connecting block 8 is fixedly connected to the wooden board. The connecting block 8 is trapezoidal in shape. After determining the position of the metal plate on the wooden board, workers can drive nails diagonally inward from the side of the metal plate. The beveled area of the connecting block 8 provides sufficient insertion space for the nails, ensuring the stability of the metal plate installation and also ensuring nail-free installation, improving the aesthetics of the installation. The connecting block 8 itself is elastic. When the metal plate expands slightly due to heat, the connecting block 8 can absorb the stress generated by the expansion of the metal plate through its own elastic deformation, preventing the metal plate from deforming or being damaged due to stress concentration, while also preventing excessive compression on the wooden backing board. This design not only improves the stability of the connection between the metal plate and the wooden backing board, but also enhances the durability and adaptability of the entire structure, enabling it to better meet the needs of use under different environmental conditions. When it is necessary to replace or repair the metal plate, simply follow the reverse operation steps to easily remove the metal plate from the wooden backing board, achieving non-destructive disassembly and greatly reducing the cost and complexity of later maintenance.
[0018] Working principle: When using the wall panel metal sheet and wooden back panel connection structure proposed in this utility model, firstly, the side of the connecting box 1 is fixedly connected to the wooden back panel, ensuring that the connecting box 1 is parallel to the ground. Then, the sliding plate 2 is installed on the side of the metal sheet, and the sliding plate 2 is made to contact the inclined area of the connecting box 1, at which point the metal sheet and the wooden board are parallel to each other. Since the sliding plate 2 can slide freely on the connecting box 1, the metal sheet can also slide freely on the side of the wooden board, which facilitates subsequent installation and adjustment.
[0019] During installation, once the metal plate slides to the appropriate position, the spring 5 inside the connecting box 1 pushes the connecting rod 4 to lift the insert rod 3, causing the insert rod 3 to insert into the slot 6 inside the slide plate 2, thereby limiting the position of the metal plate on the wooden board. This design ensures the stability of the metal plate after installation and avoids installation problems caused by the metal plate sliding.
[0020] When the metal plate needs to be disassembled or replaced, the worker can directly push the connecting rod 4 downwards through the through hole 7 in the wall of the connecting box 1, causing the insert rod 3 to slide out of the slot 6. At this point, the metal plate loses its restraint and can be easily removed from the wooden back panel. This non-destructive disassembly method greatly reduces the cost and complexity of later maintenance, and improves the service life and adaptability of the entire structure.
[0021] Meanwhile, the connecting block 8 on the side of the metal plate also plays a crucial role. The trapezoidal shape of the connecting block 8 provides sufficient insertion space for the pneumatic nails, ensuring the stability of the metal plate's installation. Furthermore, the connecting block 8 itself is elastic, absorbing stress generated by the thermal expansion of the metal plate and preventing deformation or damage due to stress concentration. This design further enhances the stability and durability of the connection between the metal plate and the wooden backing panel.
