[0031] The following will elaborate on the embodiments of the present utility model in detail, but the present utility model can be implemented in many different ways defined and covered by the claims.

[0032] Embodiment 1:

[0033] Refer to Figures 1-3 , a board, tenon grooves 11 are respectively formed on both side surfaces of the board 1. The tenon groove 11 includes a notch 12 communicating with the outside and a concave connecting part 13 extending into the board 1 through the notch 12 and recessed up and down. The height of the concave connecting part 13 is greater than the height of the notch 12. The inner surface of the notch 12 of the tenon groove 11 communicating with the outside is a plane. The up and down described herein refers to the state when the board is laid on the ground.

[0034] Preferably, the board 1 includes a decorative top layer 14 and a core layer 15 disposed below the decorative top layer 14. The tenon groove 11 is disposed in the core layer 15.

[0035] In this embodiment, the core layer 15 includes a foamed layer, a stone-plastic layer or a strengthened layer.

[0036] Preferably, the core layer 15 includes at least one upper core layer 151 and at least one lower core layer 152.

[0037] The upper core layer 151 is one of a foamed layer, a stone-plastic layer or a strengthened layer, and the lower core layer 152 is one of a foamed layer, a stone-plastic layer or a strengthened layer. Preferably, the core layer 15 includes an upper core layer 151 and a lower core layer 152, and both the upper core layer 151 and the lower core layer 15 are stone-plastic layers.

[0038] It should be noted that the notch 12 of the board 1 provided by the present utility model extends inward and depresses to form a concave connecting portion 13. This concave structure is difficult to process during the processing of the mortise and tenon groove 11 and requires a customized tool for processing. In order to reduce the processing difficulty, the mortise and tenon groove 11 can be divided into two parts, an upper part and a lower part. The upper and lower parts can be symmetrical or asymmetrical. The upper and lower parts of the mortise and tenon groove 11 are respectively processed on the upper core layer 151 and the lower core layer 152. After processing, the upper core layer 151 and the lower core layer 152 are bonded or hot-pressed to form the mortise and tenon groove 11.

[0039] Example 2:

[0040] See Figure 4 , a splicing member, applied to the board described in Example 1. The splicing member 2 includes a joint portion 21 and tenons 22 protruding upward and downward at both ends of the joint portion 21. The surface shape of the tenons 22 matches the surface shape of the concave connecting portion 13. The two tenons 22 are used to be embedded into the mortise and tenon grooves 11 of two adjacent boards 1 in a sliding manner during paving to form a fixation.

[0041] Preferably, through holes 23 are provided up and down on the splicing member 2. The through holes 23 penetrate the splicing member 2 up and down. The through holes 23 are used to hang a traction rope, and the traction rope is used to draw the splicing member 2 into the mortise and tenon groove 11 from one end of the board 1 during paving to realize the fixation of the two boards 1.

[0042] Preferably, the splicing member 2 is strip-shaped, the through holes 23 are arranged on the joint portion 21, and the through holes 23 are arranged at intervals in the length direction of the splicing member 2.

[0043] In this embodiment, the interval distance ranges from 5 to 50 cm, and the interval range of the preferred embodiment is from 7 to 15 cm.

[0044] Preferably, the splicing member 2 further includes a sunken platform 24. The sunken platform 24 is located on the joint portion 21, and the sunken platform 24 sinks relative to the outer surface of the joint portion 21. At least one of the upper and lower ends of the through hole 23 is opened on the sunken platform 24.

[0045] In addition, the through holes 23 can also be provided on the tenons 22.

[0046] Preferably, the thickest part of the cross-section of the joint part 21 is smaller than the thickest part of the cross-section of the tenon 22.

[0047] Preferably, the tenons 22 have the same shape, and the cross-section of the tenons 22 includes a part of a circle or a part of a regular polygon. That is, the shape of the cross-section of the tenons 22 includes a part of a circle or a part of a regular polygon.

[0048] Generally speaking, the board 1 includes a long side and a short side. The laying of the board 1 includes fixing the long side and fixing the short side. In the short side fixing, the splicing member 2 in the present invention can be cut into a length suitable for the short side, and then the splicing member 2 is slid into the mortise 11 to realize the fixation of two boards 1; in the long side fixing, it is difficult to push the splicing member 2 into the mortise 11 due to friction and other reasons. At this time, the towing rope can be fixed to the through hole 23, and the splicing member 2 is slid into the mortise 11 by traction to realize the fixation of two boards 1.

[0049] It should be noted that the splicing strength of the board 1 requires a high degree of fit between the splicing member 2 and the mortise 11, and there should not be too large a gap between them. The towing rope is generally fixed to the through hole 23 by winding and knotting. Inevitably, friction will be generated when the towing rope is placed between the mortise 11 and the splicing member 2, which will hinder the sliding of the splicing member 2 into the mortise 11. The problem can be avoided by setting the sinking platform 24.

[0050] In addition, the material of the splicing member 2 can be a polymer material, including: PVC, PP, PET, PE, PS, etc.

[0051] See Figure 5 , the steps of splicing the board of the present invention are as follows:

[0052] S1: Align the two sides of the two boards 1 that need to be spliced. Mortises 11 are respectively provided on the two side surfaces of the board 1. The mortise 11 includes a notch 12 communicating with the outside and a concave connecting part 13 extending and recessing from the notch 12 into the board 1. The inner surface of the notch 12 of the mortise 11 communicating with the outside is a plane. The board 1 includes a decorative top layer 14 and a core layer 15 provided below the decorative top layer 14. The mortise 11 is provided in the core layer 15;

[0053] S2: Fix the towing rope to the splicing member 2. The splicing member 2 includes a joint part 21 and tenons 22 protruding at both ends of the joint part 21. The surface shape of the tenons 22 matches the surface shape of the concave connecting part 13. Through holes 23 penetrating the splicing member 2 are provided on the upper and lower sides of the splicing member 2. The through holes 23 are used for fixing the towing rope to the splicing member 2;

[0054] S3: Use a towing rope to lead the splicing member 2 into the mortise 11 from one end of the two boards 1, and tow the splicing member 2 to slide to the other end. Embed the splicing member 2 into the mortise 11 by sliding, so as to realize the splicing of the two boards 1.

[0055] After splicing the boards, conduct multiple sets of wheelchair tests. The results are as follows:

[0056]

[0057]

[0058] In summary, on both sides of the board 1 of the present utility model, mortises 11 are respectively provided. The mortise 11 includes a notch 12 communicating with the outside and a concave connecting portion 13 extending and recessing into the board 1 through the notch 12. When assembling, the space formed by the concave connecting portion 13 and the notch 12 can be tightly combined with the matching splicing member 2, improving the use effect and splicing strength of the board 1.
