Technical Field
[0001] The utility model relates to the technical field of built-in reinforcing ribs, in particular to built-in reinforcing ribs for wood-plastic boards. Background Art
[0002] Wood plastic board is usually made of a mixture of wood fiber (such as wood powder or sawdust) and plastic resin (such as polyethylene, polypropylene, etc.). The built-in reinforcement ribs are usually high-strength materials such as steel wire, glass fiber, carbon fiber, etc. They are embedded in the interior of the wood plastic board and formed together with the wood plastic composite material during the manufacturing process. They are often used in indoor and outdoor decoration, building materials, furniture manufacturing and other fields. The built-in reinforcement ribs of wood plastic board refer to a structural design embedded in the wood plastic composite material board. The built-in reinforcement ribs are mainly used to enhance the bending strength, compressive strength and tensile strength of the wood plastic board. They can effectively improve the overall structural strength of the wood plastic board, reduce deformation and warping, and increase its service life. Built-in I-shaped steel structural metal is often used as built-in reinforcement ribs to enhance the performance of the structural cabinet board. Whether it is ordinary or light, the cross-sectional dimensions of the I-shaped steel are relatively high and narrow, and the moment of inertia of the two cross-sections is quite different. The I-shaped steel is arranged horizontally in the board. The I-shaped steel and the board are in contact through the wing plate plane, and have excellent reinforcement function.
[0003] After searching, the announcement number: CN217510127U discloses a built-in reinforcement rib, including an I-shaped steel; inwardly bent support plates are arranged on both sides of the wing plate of the I-shaped steel, and when the I-shaped steel is placed vertically in the plate, the support plate increases the contact area between the I-shaped steel and the plate, effectively reducing the pressure acting on the plate and the I-shaped steel during the bending deformation process, avoiding the situation where the I-shaped steel is placed vertically in the plate and causing damage to the plate, so that the I-shaped steel has excellent reinforcement function regardless of whether it is placed horizontally or vertically, has high adaptability, and can match plates of various sizes.
[0004] The rib dimensions in the above applications are all fixed. In actual situations, when the size of the wood-plastic board does not match the rib dimensions, the ribs need to be remade, which is not only time-consuming and labor-intensive, but also increases production costs. Utility Model Content

[0022] The following will be combined with the drawings of the specification of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The built-in reinforcement ribs of two wood-plastic boards are spliced together front and back, and the concave card slots 9 are aligned with the convex card plate 7, and the built-in reinforcement ribs of the two wood-plastic boards can be connected together smoothly.
[0024] Reference Figure 1-Figure 3 An upper fixing plate 5 is provided at the top of both ends of the extension plate 4, and a lower fixing plate 6 is provided at the bottom of both ends of the extension plate 4. The upper fixing plate 5 and the lower fixing plate 6 are respectively arranged above the convex card plate 7 and below the concave card slot 9. By installing the upper fixing plate 5 and the lower fixing plate 6, the connection between the built-in reinforcing ribs of the two wood-plastic boards is strengthened. The fixing plate can effectively maintain the stability between the built-in reinforcing ribs of the two wood-plastic boards, prevent shaking and sliding, and ensure the safety and reliability of the built-in reinforcing ribs of the wood-plastic board.
[0025] Reference Figure 1 and Figure 3 The top of the upper fixing plate 5 is symmetrically provided with an adapting groove 11, in which a bolt 10 is arranged. The adapting groove 11 is used to install the bolt 10. The adapting groove 11 can ensure that the bolt 10 will not protrude outside after installation. If part of the bolt 10 is exposed to the outside for a long time, it will affect the safety performance of the bolt 10 and its connection effect.
[0026] Reference Figure 1 and Figure 3 The bottom of the extension plate 4 is fixedly connected with a support plate 12, which is used to increase the contact area between the two sides of the built-in reinforcement ribs and the wood-plastic board, to reduce the pressure between the contact surfaces, and to enhance the adaptability of the overall structure of the built-in reinforcement ribs.
[0027] Reference Figure 1 and Figure 3 A plurality of insertion holes 13 are evenly penetrated and opened on one side of the main body 1. The insertion holes 13 are cylindrical structures, which are more stable and easier to insert than other structures. The insertion holes 13 can be used to install other external components, such as reinforcing cores 14 and other items.
[0028] Reference Figure 1 and Figure 3 A reinforcing core 14 is provided in the jack 13. The reinforcing core 14 can be made of various materials and can have different functions, such as fireproof, electric proof, waterproof and the like.

The upper fixing plate 5, the lower fixing plate 6, the convex card plate 7 and the concave card slot 9 can be connected together by means of the bolt 10.
[0030] Reference Figure 1 and Figure 3 The upper and lower sides of the main body 1 are symmetrically fixedly connected with convex plates 2 and grooves 3, which are arranged in a staggered shape. The convex plates 2 and the grooves 3 can be used to apply the foaming agent and adhere to the wood-plastic board, which increases the retention space of the foaming agent, enhances the bonding strength between the main body 1 and the wood-plastic board, and saves costs. The reinforcing ribs can also be mixed with the raw materials of the wood-plastic board. The stacked undulating surface can also increase the contact area with the raw materials, which can effectively share the extrusion pressure and enhance the strength and stability.
[0031] Working principle: According to the length of the wood-plastic board, select the number of built-in reinforcing ribs to be assembled, align the convex card plate 7 of one built-in reinforcing rib with the concave card slot 9 of another built-in reinforcing rib, and then align the upper fixing plate 5 and the lower fixing plate 6 with the screw hole 8 and place them. Then put the bolt 10 into the adapter slot 11. The bolt 10 is adapted to the screw hole 8. After tightening, the upper fixing plate 5 and the lower fixing plate 6 and the two built-in reinforcing ribs are connected together. Follow the same operation to connect and fix the other side of the main body 1, and then continue the operation according to the length. Then insert the reinforcing core 14 into the jack 13 according to actual needs to add different functions, and then choose the production process, whether to use foam glue for bonding or mixed production.
