Description

Technical Field

[0001] The utility model relates to the field of building materials, in particular to a composite board. Background Technique

[0002] At present, a composite board is a board composed of multiple laminated boards, which has various advantages and uses and is widely used in the construction field. In the existing composite boards, for example, a Chinese patent document discloses a technical solution with a patent application number of 201821027325.9 and a name of "a composite board with snap connection". This solution mainly includes a first wooden board, a heat preservation board, and a second wooden board stacked in sequence. Among them, the first wooden board and the heat preservation board are fixed together by glue, and the second wooden board and the heat preservation board are also fixed together by glue. Although the method of fixing with glue can very conveniently and quickly fix multiple layers of boards together, the glue more or less contains a certain amount of volatile organic compounds such as formaldehyde and benzene, which is not only not environmentally friendly, but these substances will also have an adverse impact on the health of users. At the same time, in order to improve the connection firmness between the heat preservation board and the first wooden board and the second wooden board, this solution also processes snap blocks and snap grooves with matching concave and convex shapes on the surfaces of these three boards respectively to increase the contact area between the three boards and improve the stability of glue bonding. However, this requires planing processing of the boards, increasing the processing difficulty of the boards and causing more board waste, resulting in waste. Therefore, it is very necessary to design a composite board without glue fixing and bonding to better meet people's application needs. Content of the Utility Model

[0003] The purpose of the utility model is to solve the above problems and deficiencies, and provide a composite board. By setting a snap component, the composite board can achieve the purpose of rapid assembly and fixation without using glue for the two solid wooden boards and the heat preservation board, completely abandoning the application of glue, making the composite board not release volatile organic compounds such as formaldehyde and benzene, being more environmentally friendly, thus avoiding adverse effects on the health of users. Moreover, for the two solid wooden boards and the heat preservation board, flat-surfaced boards can be directly used, greatly reducing the processing difficulty of the boards and reducing board waste to avoid waste of board resources.

[0004] The technical solution of the utility model is realized as follows: A composite board includes two solid wood boards stacked together and a heat preservation board disposed between the two solid wood boards. It is characterized in that it further includes a buckle assembly. The buckle assembly includes a buckle member and two buckle seats. The two buckle seats are respectively disposed on the two solid wood boards. The buckle member is provided with two mounting parts with buckle notches. The buckle member is respectively mounted on the two buckle seats through the two buckle notches, so that the heat preservation board is limited between the two solid wood boards; The buckle seat is further provided with a first-stage limiting convex part, so that the mounting part is limited between the first-stage limiting convex part and the solid wood board. The buckle notch is further provided with a second-stage limiting convex part for limiting the buckle seat in the buckle notch.

[0005] Preferably, the number of the second-stage limiting convex parts in each buckle notch is two, and the two second-stage limiting convex parts are arranged along the mounting direction of the buckle notch to form a two-stage anti-disengagement limiting structure.

[0006] Preferably, a plurality of reinforcing rib pieces are further disposed between the buckle member and the two mounting parts, and each reinforcing rib piece is respectively arranged along the length direction of the buckle member.

[0007] Preferably, 45-degree chamfer structures are respectively disposed at both ends of the two mounting parts in the length direction, and the 45-degree chamfer structures extend to the buckle member.

[0008] Preferably, the buckle member and the two mounting parts are of an integrally formed structure.

[0009] Preferably, the utility model further includes a locking screw. The buckle seat includes a mounting seat and a buckle part disposed on the mounting seat. The mounting seat is fixed on the solid wood board through the locking screw, and the first-stage limiting convex part is disposed on the buckle part.

[0010] Preferably, the first-stage limiting convex part, the buckle part and the mounting seat are of an integrally formed structure.

[0011] Preferably, the solid wood board is further provided with an embedding groove for the mounting seat to be embedded.

[0012] Preferably, the number of the buckle assemblies is four, and the four buckle assemblies are arranged around the heat preservation board.

[0013] Preferably, the heat preservation board is a rigid polyurethane foam board.

[0014] Advantages of the present utility model: By providing a snap component, the present utility model enables the quick assembly and fixation of two solid wood boards and a thermal insulation board without using glue, completely eliminating the use of glue, making the composite board not release volatile organic compounds such as formaldehyde and benzene, being more environmentally friendly, and thus avoiding adverse effects on the health of users. Moreover, by providing a first limiting protrusion and a second limiting protrusion, under such dual limiting effects, it can ensure that the snap member and the snap seat are not prone to loosening, guaranteeing the stability of the connection, thereby ensuring that the two solid wood boards and the thermal insulation board can be firmly stacked together, not easily loosening, and there is no need to process a structure with concave-convex shapes on the surfaces of these three boards, and these three boards can directly use flat-surface boards, greatly reducing the processing difficulty of the boards, reducing board waste, and avoiding waste of board resources. At the same time, the present utility model uses solid wood boards, so it does not contain formaldehyde itself and is more environmentally friendly to use. Brief Description of the Drawings

[0021] As Figure 1 shown in Figure 2 the figure, a composite board of the present utility model includes two solid wood boards 1 stacked together and a thermal insulation board 2 disposed between the two solid wood boards 1. In order to achieve the purpose proposed by the present utility model, as Figure 3As shown in the figure, the utility model further includes a buckle assembly 3. The buckle assembly 3 includes a buckle member 31 and two buckle seats 32. The two buckle seats 32 are respectively arranged on two solid wood boards 1. The buckle member 31 is provided with two mounting parts 33 with buckle notches 34. The buckle member 31 is respectively mounted on the two buckle seats 32 through the two buckle notches 34, so that the two solid wood boards 1 are fixed together, and the heat preservation board 2 is limited between the two solid wood boards 1. The buckle seat 32 is further provided with a first-stage limiting convex part 321, so that the mounting part 33 is limited between the first-stage limiting convex part 321 and the solid wood board 1. The buckle notch 34 is further provided with a second-stage limiting convex part 341 for limiting the buckle seat 32 in the buckle notch 34. By arranging the buckle assembly 3, the two solid wood boards 1 and the heat preservation board 2 can be quickly assembled and fixed without using glue, completely eliminating the application of glue, so that the composite board will not release volatile organic compounds such as formaldehyde and benzene, and is more environmentally friendly, thus avoiding adverse effects on the health of users. Moreover, for the two solid wood boards 1 and the heat preservation board 2, flat-surfaced boards can be directly used, greatly reducing the processing difficulty of the boards, reducing board waste, and avoiding waste of board resources.

[0022] In order to further improve the anti-loosening performance, as Figure 5 shown, the number of the second-stage limiting convex parts 341 in each buckle notch 34 is two, and the two second-stage limiting convex parts 341 are arranged along the mounting direction of the buckle notch 34 to form a two-stage anti-loosening limiting structure. This can ensure that the buckle member 31 and the buckle seat 32 are not easily loosened, and ensure the stability of the connection.

[0023] In order to further improve the overall structural strength of the buckle member 31, as Figure 4 shown, a plurality of reinforcing rib plates 35 are further arranged between the buckle member 31 and the two mounting parts 33, and each reinforcing rib plate 35 is arranged along the length direction of the buckle member 31. This can not only enhance the overall structural strength of the buckle member 31, improve the compressive and anti-bending deformation performance of the buckle member 31, but also help to improve the overall structural strength of the composite board and the reliability of the connection structure between the two solid wood boards 1 and the heat preservation board 2.

[0024] As Figure 4 and Figure 5 shown, 45-degree chamfer structures 36 are respectively arranged at both ends of the two mounting parts 33 in the length direction, and the 45-degree chamfer structures 36 extend to the buckle member 31. By arranging the 45-degree chamfer structures 36, when using a plurality of buckle assemblies 3 to enclose and limit the heat preservation board 2, a 90-degree angular frame structure can be formed by splicing every two adjacent buckle assemblies 3, corresponding to the shape of the entire composite board, covering the heat preservation board 2, and the assembly structure of the buckle assembly 3 is not exposed, so that the appearance of the entire composite board is more concise.

[0025] To make the manufacturing of the buckle member 31 and the two clamping portions 33 easier and the overall structural strength higher, as Figure 4 shown, the buckle member 31 and the two clamping portions 33 are of an integrally formed structure.

[0026] To further improve the installation structure of the buckle seat 32 and the solid wood board 1, as Figure 3 shown, the present utility model further includes a locking screw 4. The buckle seat 32 includes a mounting seat 322 and a buckle portion 323 provided on the mounting seat 322. The mounting seat 322 is fixed on the solid wood board 1 through the locking screw 4. The first limiting convex portion 321 is provided on the buckle portion 323, and the buckle notch 34 is clamped on the buckle portion 323. In this way, the buckle seat 32 can be easily installed and disassembled and is very firmly installed on the solid wood board 1.

[0027] During the actual application process, as Figure 6 shown, the first limiting convex portion 321, the buckle portion 323 and the mounting seat 322 are of an integrally formed structure. In this way, the manufacturing of the buckle seat 32 is easier and the overall structural strength is higher.

[0028] To prevent a large gap from existing between the insulation board 2 and the solid wood board 1 during the installation of the mounting seat 322, as Figure 3 shown, an embedding groove 11 for embedding the mounting seat 322 is further provided on the solid wood board 1. In this way, it can be ensured that the connection and contact between the insulation board 2 and the solid wood board 1 are very tight and will not shake randomly.

[0029] During the actual application process, as Figure 2 shown, the number of the buckle assemblies 3 is four, and the four buckle assemblies 3 are arranged around the insulation board 2. Through such a structural design, the insulation board 2 can be surrounded, so that the insulation board 2 is limited between the four buckle assemblies 3, thereby preventing the insulation board 2 from detaching from the two solid wood boards 1.

[0030] During the actual application process, the insulation board 2 is a rigid polyurethane foam board. Its polyurethane material has very good heat insulation performance and waterproof performance, thereby improving the heat insulation performance and waterproof performance of the composite board.
