Description

Technical Field

[0001] The present invention relates to the technical field of solid wood boards, and particularly to a wood-plastic hybrid multi-layer solid wood board. Background Art

[0002] Currently, consumers prefer to choose pure solid wood furniture during consumption, which has led to an increase in the price of raw wood materials. Therefore, the price of finished furniture has also been rising continuously, causing great pressure on the market. To solve this problem well, some composite artificial boards have emerged in the material market, such as common finger-jointed boards and plywood, etc. Such boards are formed by multi-layer splicing.

[0003] During the use of existing multi-layer solid wood boards, misalignment is likely to occur between the wooden bottom board, plastic core board, noise reduction part, reinforcement board and flame retardant board. At this time, the overall strength will be affected. Currently, during the processing of solid wood boards, although they can be assembled by splicing, the adhesion and fixing effect of glue on the splicing structure cannot be improved by optimizing the splicing structure to prevent cracking at the splicing structure and avoid the loss of the limiting effect of the splicing structure. When fixing, although it can be fixed with glue and nails, there is still room for improvement in its fixing effect. Summary of the Invention

[0004] In view of this, the present invention provides a wood-plastic hybrid multi-layer solid wood board to solve the problem that misalignment is likely to occur between the wooden bottom board, plastic core board, noise reduction part, reinforcement board and flame retardant board during the use of existing multi-layer solid wood boards, which will affect the overall strength at this time. Currently, during the processing of solid wood boards, although they can be assembled by splicing, the adhesion and fixing effect of glue on the splicing structure cannot be improved by optimizing the splicing structure to prevent cracking at the splicing structure and avoid the loss of the limiting effect of the splicing structure. When fixing, although it can be fixed with glue and nails, there is still room for improvement in its fixing effect.

[0005] A wood-plastic hybrid multi-layer solid wood board of the present invention is achieved by the following specific technical means: The present invention provides a wood-plastic hybrid multi-layer solid wood board, specifically including a wooden bottom board; A plastic core board is arranged on the top of the wooden bottom board.

[0006] Furthermore, the top end surface of the wooden bottom board is transversely provided with first clamping grooves in a linear array, and the top end surface of the wooden bottom board is longitudinally provided with first clamping grooves in a linear array. The first clamping grooves provided transversely and longitudinally are both rectangular groove-shaped structures.

[0007] Further, the bottom end surface of the plastic core board is transversely formed with clamping protrusions in a linear array, and the bottom end surface of the plastic core board is longitudinally formed with clamping protrusions in a linear array. The clamping protrusions are matched with the first clamping grooves, and the clamping protrusions are clamped and connected with the first clamping grooves. The clamping protrusions and the first clamping grooves together form a clamping and fixing structure for the plastic core board and the wooden bottom board.

[0008] Further, glue is applied to both the clamping protrusions and the first clamping grooves. The clamping protrusions are rectangular block structures, and a first auxiliary groove is opened on the bottom end surface and both side end surfaces of the clamping protrusions. The first auxiliary groove is a semi-cylindrical groove structure, and glue is filled in the first auxiliary groove.

[0009] Further, sound-absorbing holes are opened on the clamping protrusions. The sound-absorbing holes are cylindrical hole structures and are sound-absorbing structures. During assembly, first apply glue to the clamping protrusions and the first clamping grooves, and then directly clamp the clamping protrusions with the first clamping grooves. During use, the glue residue amount at the connection between the clamping protrusions and the first clamping grooves can be increased through the setting of the first auxiliary grooves, thereby improving the fixing strength of the plastic core board and the wooden bottom board; during use, noise absorption can be achieved through the setting of the sound-absorbing holes, improving the noise reduction effect.

The seat body is fixed on the top end surface of the plastic core board. The seat body is a rectangular frame structure, and eight noise reduction blocks are filled in the seat body. The noise reduction blocks are made of hard sponge material. During installation, directly fix the seat body on the plastic core board with nails and glue, then fill eight noise reduction blocks in the seat body and fix them with glue; during use, noise absorption can be achieved through the setting of the noise reduction blocks. During maintenance, since there are eight noise reduction blocks in total, they can be replaced individually when damaged.

[0011] Further, a reinforcing plate is fixed on the top end surface of the seat body. The reinforcing plate is made of wood, and a flame retardant plate is fixed on the top of the reinforcing plate with nails. Two second clamping grooves are opened on the flame retardant plate, and both second clamping grooves are rectangular groove structures.

Three fixing screws are threadedly connected in each second auxiliary groove, and the six fixing screws are all threadedly connected to the sound-absorbing holes on the plastic core board.

[0014] Further, six clamping blocks are clamped at the second auxiliary groove and the second clamping groove. The clamping blocks are of a concave structure, and the clamping blocks are fixing parts for the frame body and the flame retardant board.

[0015] Further, two adjustment grooves are provided at the adjustment part of each fixing screw. The adjustment grooves are of a rectangular groove structure. During installation, directly sleeved the frame body outside the wooden bottom board, plastic core board, noise reduction part, reinforcement board and flame retardant board, and then fixed it with six fixing screws. After fixing, directly clamp the six clamping blocks with the second auxiliary groove and the second clamping groove; during disassembly, when the adjustment part of the fixing screw is damaged, directly use a screwdriver to clamp in the adjustment groove for adjustment.

[0016] Further, limit blocks are fixed on both the front end face and the rear end face of the wooden bottom board by nails. The limit blocks are of a rectangular plate structure and are flush with the clamping blocks. The limit blocks are strengthening structures of the frame body. When installing the limit blocks, directly fix them on the frame body with nails.

[0017] Beneficial effects: 1. There is a fixing component.
