Description

Technical Field

[0001] This invention relates to the field of building construction technology, and specifically to a double-layer concave edge keel. Background Technology

[0002] In modern housing construction projects, ceiling decoration is one of the most common interior decorations. The ceiling structure usually includes ceiling connection devices and ceiling panels. The ceiling connection devices are the edge keel fixed to the building structure and provide the fixing points for the ceiling panels.

[0003] To save on materials and usage costs, existing edge keel components are mostly single-layer structures, relying on the strength of the wood or metal itself to provide support and hanging strength. This undoubtedly presents the problem of unreliable structural strength and cannot guarantee construction quality.

[0004] Therefore, there is an urgent need for a double-layered concave edge keel to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a double-layer concave side keel, which solves the problem of low strength and single structure of the side keel in the prior art, affecting the construction quality.

[0006] To achieve the above objectives, the present invention provides a double-layer concave edge keel, comprising a vertical wall-connecting structure and a horizontal hanging structure;

[0007] The horizontal hanging structure includes a spaced double-layer panel, with the upper and lower sides of one end of the spaced double-layer panel integrally connected, and the upper and lower sides of the other end of the spaced double-layer panel vertically fixed to the vertical wall connection structure.

[0008] The upper and lower sides of the spaced double-layer plate are both recessed in the middle to form a recessed connecting part.

[0009] The vertical wall connection structure includes a double-layer panel, the bottom ends of the left and right sides of the double-layer panel are integrally connected to the upper and lower sides of the spaced double-layer panel, respectively.

[0010] The two sides of the adhesive double-layer board are fixed to each other.

[0011] By adopting this technical solution, the main load-bearing horizontal hanging structure for the decorative panel installation is set as a spaced double-layer panel with one end connected to the vertical wall structure and the other end integrally connected. When either side of the spaced double-layer panel is subjected to force, because the upper and lower panels are an integral structure, the other side will cooperate with the vertical wall structure to provide a counterforce, thereby increasing the load-bearing strength of the horizontal hanging structure, ensuring the stability of the decorative panel after installation, and thus improving construction quality. The concave middle panel of the spaced double-layer panel forms a concave connecting part, which, in addition to leaving elasticity to prevent damage to the decorative panel when connected, also gives the spaced double-layer panel better bending resistance, further increasing... The structural strength of the horizontal hanging structure and the stability of the decorative panels after installation are ensured to guarantee construction quality. This allows the vertical wall ties and the horizontal hanging structure to form an integrated structure, increasing the connection strength between each part and thus increasing the overall structural strength of the edge keel. It also provides a prerequisite for reducing the manufacturing difficulty of the edge keel. After the left and right sides of the fitted double-layer board are fixed together, they can work together to provide stable support for the upper and lower sides of the spaced double-layer board. This prevents the problem of reduced load-bearing capacity of the horizontal hanging structure due to displacement caused by stress between the upper and lower sides of the spaced double-layer board, thereby increasing the overall structural strength of the edge keel and ensuring subsequent construction quality.

[0012] Furthermore, the integrated structure composed of the laminated double-layer plate and the spaced double-layer plate is formed by continuously bending a single plate.

[0013] By adopting this technical solution, the connection strength between the various structural components that make up the side keel is ensured, which is beneficial to increasing the structural strength of the side keel after it is formed. At the same time, the side keel can be manufactured by a single processing method, which reduces the manufacturing difficulty of the side keel.

[0014] Furthermore, it also includes a first connecting hole, which is evenly distributed along the length of the vertical wall-connecting structure and is provided on the vertical wall-connecting structure.

[0015] By adopting this technical solution, an additional first connecting hole is provided to allow the screws used to fix the vertical wall tie structure to pass through, which facilitates the quick connection of the vertical wall tie structure to the wall to be connected by screws, eliminating the drilling process on the vertical wall tie structure during construction and reducing the construction difficulty.

[0016] Furthermore, it also includes a second connecting hole, which is evenly distributed along the length of the transverse hanging structure on the upper concave connecting part, and the second connecting hole also penetrates the upper and lower sides of the spaced double-layer plate.

[0017] By adopting this technical solution, a second connecting hole is added to provide a place for screws to be inserted to connect the decorative panel. This makes it easy to quickly connect the decorative panel to the horizontal hanging structure with screws, eliminating the drilling process on the horizontal hanging structure during construction and reducing the difficulty of construction.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] The main load-bearing horizontal hanging structure for the decorative panel installation is designed as a double-layered panel with one end connected to the vertical wall structure and the other end integrally connected. When either side of the double-layered panel is subjected to force, since the upper and lower panels are an integral structure, the other side will cooperate with the vertical wall structure to provide a counterforce, thereby increasing the load-bearing strength of the double-layered panel. At the same time, the concave middle of the double-layered panel also gives it a better bending resistance, increasing the structural strength of the horizontal hanging structure and the stability of the decorative panel after installation, thus ensuring construction quality.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Please see the appendix Figure 1 and 3This invention provides a double-layer concave edge keel, including a vertical wall-connecting structure 1 for connecting to the wall and a horizontal hanging structure 2 for connecting decorative panels. The horizontal hanging structure 2 includes a spaced double-layer board, with the upper and lower sides of one end of the spaced double-layer board integrally connected, and the upper and lower sides of the other end of the spaced double-layer board vertically fixed to the vertical wall-connecting structure 1. When either side of the spaced double-layer board is subjected to force, since the upper and lower sides are an integral structure, the other side will cooperate with the vertical wall-connecting structure 2 to provide a counterforce, thereby increasing the load-bearing strength of the horizontal hanging structure 2, ensuring the stability of the decorative panel after installation, and thus improving the construction quality. The upper and lower sides of the spaced double-layer board are both concave in the middle to form a concave connecting part 3. In addition to leaving elastic margin to prevent damage to the decorative panel when connecting with it, the spaced double-layer board also has a better bending resistance, further increasing the structural strength of the horizontal hanging structure 2 and the stability of the decorative panel after installation, so as to ensure the construction quality.

[0026] Furthermore, in order to make the vertical wall connection structure 1 and the horizontal hanging structure 2 form an integrated structure, and to increase the connection strength between the various parts constituting the edge keel so as to increase the overall structural strength of the edge keel, the vertical wall connection structure 1 is set as an adhesive double-layer board, and the bottom ends of the left and right sides of the adhesive double-layer board are integrally connected to the upper and lower sides of the spaced double-layer board, respectively. This also provides a prerequisite for reducing the manufacturing difficulty of the edge keel.

[0027] Furthermore, the left and right sides of the laminated double-layer board are fixed together. After the left and right sides of the laminated double-layer board are fixed together, the left and right sides of the laminated double-layer board can cooperate to provide stable support for the upper and lower sides of the interval double-layer board. This will prevent the problem of the horizontal hanging structure 2 becoming less effective due to the displacement between the upper and lower sides of the interval double-layer board caused by the force. This will increase the structural strength of the entire edge keel and ensure the quality of subsequent construction.

[0028] Furthermore, to ensure the connection strength between the various structural components constituting the edge keel and the structural strength of the edge keel itself, the integrated structure composed of the fitted double-layer board and the spaced double-layer board is designed to be formed by continuous bending of a single board; specifically, please refer to the appendix. Figure 1After a single board is placed horizontally, it is bent for the first time so that its left end forms the right side of the fitted double-layer board. After reserving the first horizontal section, the board is bent a second and third time so that the remaining board is parallel and higher than the first horizontal section. After reserving the second horizontal section, the board is bent a fourth and fifth time so that the remaining board is level with the first horizontal section. The board formed by the second, third, fourth, and fifth bends is the first concave part of the upper side of the spaced double-layer board. After reserving the third horizontal section, the remaining board is bent downwards a sixth time so that it is parallel to the third horizontal section. After reserving the fourth horizontal section, the board is bent a seventh and eighth time. The remaining board body after bending is parallel and higher than the fourth horizontal board body; after reserving the fifth horizontal board body, the board body is bent for the ninth and tenth times, so that the remaining board body after bending is level with the fourth horizontal board body. The board body formed by the seventh, eighth, ninth and tenth bending forms the second concave part of the lower side of the spaced double-layer board body, and the second concave part of the board body is parallel to the first concave part of the board body and together forms the concave connecting part 3 on the spaced double-layer board body; the sixth horizontal board body is reserved, and the remaining board body is bent upwards for the eleventh time with the intersection of the left side of the right side of the fitted double-layer board body and the remaining board body as the bending point to form the left side of the fitted double-layer board body. Thus, the edge keel is formed by continuous bending of a single board body.

[0029] Please see Figure 2 In order to facilitate the quick connection of the vertical wall connection structure 1 to the wall to be connected by screws, and to eliminate the drilling process on the vertical wall connection structure 1 during construction to reduce the construction difficulty, a first connecting hole 4 is also included. The first connecting hole 4 is evenly distributed on the vertical wall connection structure 1 along the length direction of the vertical wall connection structure 1.

[0030] Furthermore, in order to facilitate the quick connection of the decorative panel to the horizontal hanging structure 2 with screws, eliminating the drilling process on the horizontal hanging structure 2 during construction and reducing construction difficulty, a second connecting hole 5 is also included. The second connecting hole 5 is evenly distributed on the upper concave connecting part 3 along the length direction of the horizontal hanging structure 2, and the second connecting hole 5 also penetrates the upper and lower sides of the spaced double-layer panel.

[0031] For example, in order to prevent the screws used for connecting the decorative panel from being too close to the edge of the decorative panel and causing it to crack when the decorative panel is connected to the horizontal hanging structure 2, the overall width of the horizontal hanging structure 2 is set to 60mm, the width of the upper concave connecting part 3 is set to 36mm, the upper concave depth is set to 4mm, and the second connecting hole 5 for passing through the screw is located in the middle position in the width direction of the upper concave connecting part 3.

[0032] To ensure the structural strength of the support structure after the horizontal hanging structure 2 and the vertical wall connection structure 1 are combined, and to reduce the longitudinal space occupied, the distance between the upper and lower layers of the main double-layer plate of the horizontal hanging structure 2 is set to 2mm.

[0033] To ensure that the vertical wall connection structure 1 can be securely connected to the wall by screws, and that the height of the recessed connecting part 3 will not affect the installation of screws on the vertical wall connection structure 1, the height of the vertical wall connection structure 1 is set to 25mm, and the first connecting hole 4 for passing through the screw is located at the middle position in the height direction of the vertical wall connection structure 1.

[0034] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
