There is a waiting time from the coating of the waterproof layer to the coating of the wear-resistant layer. The wear-resistant layer generally includes a coating containing wear-resistant particles, such as silicon carbide, alumina, etc.

[0031] Referring to Figure 1 The utility model discloses a kind of water and wear-resistant composite boards, including first plate body 100, second plate body 200 and third plate body 300.

[0034] The entire composite board is assembled by attachment, so the wear-resistant layer can be coated on the surface of the second plate body 200 and the surface of the third plate body 300 in advance. When the composite board is finally manufactured, the second plate body 200 is attached to one side surface of the first plate body 100, and the third plate body 300 is attached to the opposite side surface of the first plate body 100. Then, the entire composite board can be directly coated with a waterproof layer, and there is no need to wait for the wear-resistant layer to be formed. It should be understood that the second plate body 200 and the third plate body 300 are respectively located on both sides of the first plate body 100, and can both protect the first plate body 100, so only the surfaces of the second plate body 200 and the third plate body 300 need to be coated with a wear-resistant layer.

[0035] It should be understood that the plate surface of the first plate body 100 refers to the surface with the largest area of the first plate body 100; the surface of the second plate body 200 refers to all surfaces of the second plate body 200, including the plate surface and the side surface of the second plate body 200. The surface of the third plate body 300 has the same meaning as the surface of the second plate body 200.

[0036] Referring to Figure 2 It can be understood that the one side plate surface of the first plate body 100 is provided with a first dovetail groove, the other side plate surface of the first plate body 100 is provided with a second dovetail groove, the plate surface of the second plate body 200 is provided with a third dovetail groove, the plate surface of the third plate body 300 is provided with a fourth dovetail groove, the second plate body 200 is attached to the first plate body 100, so that the first dovetail groove and the third dovetail groove are aligned and surround a groove body, and the first dovetail groove and the third dovetail groove are inserted with a first dovetail strip 111; the third plate body 300 is attached to the first plate body 100, so that the second dovetail groove and the fourth dovetail groove are aligned and surround a groove body, and the second dovetail groove and the fourth dovetail groove are inserted with a second dovetail strip 121; the first dovetail groove, the third dovetail groove and the first dovetail strip 111 constitute the first connecting structure 110, and the second dovetail groove, the fourth dovetail groove and the second dovetail strip 121 constitute the second connecting structure 120.

[0037] After the second plate body 200 is attached to the first plate body 100, the first dovetail strip 111 is inserted into the groove formed by the first dovetail groove and the third dovetail groove from the side, so that the second plate body 200 and the first plate body 100 can be fixed. Similarly, after the third plate body 300 is attached to the first plate body 100, the second dovetail strip 121 is inserted into the groove formed by the second dovetail groove and the fourth dovetail groove from the side, so that the third plate body 300 and the first plate body 100 can be fixed. It should be understood that the fixation here refers to the restriction of movement in the direction perpendicular to the surface of the first plate body 100.

[0038] It can be understood that the projections of the first dovetail groove and the second dovetail groove on the surface of the first plate body 100 are perpendicular to each other. That is, the insertion directions of the first dovetail strip 111 and the second dovetail strip 121 are also perpendicular to each other. The tendency of relative sliding between the second plate body 200 and the first plate body 100 and the tendency of relative sliding between the third plate body 300 and the first plate body 100 are perpendicular to each other, which can minimize the possibility of simultaneous sliding of the second plate body 200 and the third plate body 300.

[0039] It can be understood that an adhesive layer is provided between the first dovetail strip 111 and the first dovetail groove, the third dovetail groove, and an adhesive layer is provided between the second dovetail strip 121 and the second dovetail groove, the fourth dovetail groove.

[0040] In order to further fix the second plate body 200 and the third plate body 300, after the first dovetail groove, the third dovetail groove is coated with an adhesive, and the first dovetail strip 111 is inserted between the first dovetail groove and the third dovetail groove, the adhesive forms an adhesive layer, which can have a fixing effect in the axial direction of the first dovetail strip 111, preventing lateral sliding between the second plate body 200 and the first plate body 100. Similarly, after the second dovetail groove, the fourth dovetail groove is coated with an adhesive, and the second dovetail strip 121 is inserted between the second dovetail groove and the fourth dovetail groove, the adhesive forms an adhesive layer, which can have a fixing effect in the axial direction of the second dovetail strip 121, preventing lateral sliding between the third plate body 300 and the first plate body 100.

[0041] It can be understood that an adhesive layer is provided between the first plate body 100 and the second plate body 200, and an adhesive layer is provided between the first plate body 100 and the third plate body 300.

[0042] The adhesive layer between the first plate body 100 and the second plate body 200 can further prevent lateral sliding between the second plate body 200 and the first plate body 100; the adhesive layer between the first plate body 100 and the third plate body 300 can further prevent lateral sliding between the third plate body 300 and the first plate body 100.

[0043] It can be understood that the thickness of the second plate body 200 is 20% to 50% of the thickness of the first plate body 100, and the thickness of the third plate body 300 is 20% to 50% of the thickness of the first plate body 100.

[0044] Since the second plate body 200 and the third plate body 300 mainly play a role in protecting the first plate body 100 and providing wear resistance, the second plate body 200 and the third plate body 300 should not be too thick, and are preferably within the range of 20% to 50% of the thickness of the first plate body 100. For example, if the thickness of the first plate body 100 is 10 mm, the thickness of the second plate body 200 and the third plate body 300 can be 3 mm, and the thickness of the entire composite plate will reach 16 mm.

[0045] It can be understood that the plate surface of the first plate body 100 is provided with a placing groove 130, and a steel bar 131 is arranged in the placing groove 130, and the steel bar 131 is located between the first plate body 100 and the second plate body 200 or between the first plate body 100 and the third plate body 300.

[0046] The steel bar 131 can effectively keep the entire composite plate in a flat state, and the steel bar 131 can resist the natural bending of the first plate body 100, the second plate body 200 and the third plate body 300. It should be understood that the placing groove 130 and the steel bar 131 can be provided between the first plate body 100 and the second plate body 200 and between the first plate body 100 and the third plate body 300 at the same time.

[0047] It can be understood that the placing groove 130 is arranged on the plate surface of the first plate body 100 facing the second plate body 200, and the placing groove 130 is perpendicular to the first dovetail groove.

[0048] When the placing groove 130 is perpendicular to the first dovetail groove, the steel bar 131 is perpendicular to the first dovetail bar 111, and in the plane, it can be divided into X direction and Y direction, wherein the X direction and the Y direction are perpendicular to each other, the composite plate can bend along the X direction or the Y direction, assuming that the first dovetail bar 111 is parallel to the X direction, then the steel bar 131 will be parallel to the Y direction, then the first dovetail bar 111 can resist the bending of the composite plate along the X direction, and the steel bar 131 can resist the bending of the composite plate along the Y direction.

[0049] Referring to Figure 3 It can be understood that the groove depth of the placing groove 130 is greater than the groove depth of the first dovetail groove, and the steel bar 131 is located between the first dovetail bar 111 and the first plate body 100 at the intersection position of the placing groove 130 and the first dovetail groove.

[0050] The groove depth of the placing groove 130 is greater than the first dovetail groove, and the steel bar 131 is placed at the bottom of the placing groove, which can avoid the first dovetail bar 111.

[0051] With reference to Figure 4 As shown in FIG. 1, it can be understood that the end of the first dovetail bar 111 is provided with a connecting nail 400, the connecting nail 400 comprises a first nail part 410, a second nail part 420 and a third nail part 430, the first nail part 410, the second nail part 420 and the third nail part 430 are all in strip shape, the first nail part 410 and the second nail part 420 are respectively arranged at two ends of the third nail part 430, the first nail part 410 is perpendicular to the third nail part 430, the second nail part 420 is perpendicular to the third nail part 430, the first nail part 410 and the second nail part 420 are both nailed into the first plate body 100, and the third nail part 430 abuts against the end surface of the first dovetail bar 111.

[0052] The connecting nail 400 can prevent the axial movement of the first dovetail bar 111, and prevent the installed first dovetail bar 111 from being taken out. It needs to be understood that the end of the second dovetail bar 121 can also be provided with the connecting nail 400, so as to prevent the installed second dovetail bar 121 from being taken out.
