Description

Technical Field

[0001] The utility model relates to the technical field of double-sided concave-convex drainage plates, in particular to an assembling structure of double-sided concave-convex drainage plates. Background Technique

[0002] The plastic drainage plate is made of polystyrene or polyethylene as the raw material, and the plastic bottom plate is stamped into conical protrusions or convex points (or hollow cylindrical porous) with stiffening ribs. Among them, the double-sided drainage plate has protrusions formed on both the upper and lower surfaces. There are round holes on the protrusions on one side, and the protrusions on the other side are in a sealed state. During the construction process, when the side with round holes faces down, the drainage effect can be achieved. If the side with round holes faces up, it can play the role of both water storage and drainage;

[0003] In order to facilitate the assembly of double-sided concave-convex drainage plates, there is a sheet-assembled double-sided concave-convex drainage plate on the market. This kind of double-sided concave-convex drainage plate forms "T"-shaped blocks on two adjacent edges, and "T"-shaped grooves are formed at the bottoms of the other two adjacent edges. When two double-sided concave-convex drainage plates are spliced, the "T"-shaped blocks are clamped inside the "T"-shaped grooves to realize the connection of the two double-sided concave-convex drainage plates, and the operation is simple and convenient.

[0004] However, in the actual operation process, since there is only a horizontal limiting force between the "T"-shaped block and the "T"-shaped groove and no vertical limiting force, when the force on the top of the double-sided concave-convex drainage plate is uneven, the edges of the double-sided concave-convex drainage plate are prone to warping, resulting in loose splicing. Based on this, an assembling structure of double-sided concave-convex drainage plates is provided. Content of the Utility Model

[0005] The purpose of the utility model is to provide an assembling structure of double-sided concave-convex drainage plates to solve the problems in the above background.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An assembling structure of double-sided concave-convex drainage plates includes a drainage plate main body composed of a base plate, a through-hole protrusion, and a sealing protrusion. The through-hole protrusion and the sealing protrusion are respectively fixed on the upper and lower end faces of the base plate, and the through-hole protrusion and the sealing protrusion are distributed in a staggered matrix. T-shaped blocks are fixedly connected to two adjacent edges of the base plate, and T-shaped grooves are opened at the bottoms of the other two adjacent edges of the base plate. The T-shaped blocks and the T-shaped grooves are symmetrically distributed with the center of the base plate as the center;

[0007] When two drainage plate main bodies are spliced, the T-shaped blocks are clamped inside the T-shaped grooves to realize the horizontal limit of the two drainage plate main bodies;

[0008] The edge side of the substrate connected to the T-shaped block is provided with an arc-shaped strip groove, and the other two adjacent edges of the substrate corresponding to the position of the T-shaped groove are fixedly connected with arc-shaped clamping strips, and the arc-shaped clamping strips are clamped inside the arc-shaped strip groove to realize the vertical limit of the two drainage plate bodies.

[0009] As a further scheme of the present utility model: the bottom of the T-shaped block is flush with the lower surface of the substrate, and the outer wall size of the T-shaped block matches the inner wall size of the T-shaped groove.

[0010] As a further scheme of the present utility model: the arc-shaped strip groove is located above the T-shaped block, the arc-shaped clamping strip is located above the T-shaped groove, and the outer wall size of the arc-shaped clamping strip matches the inner wall size of the arc-shaped strip groove.

[0011] As a further scheme of the present utility model: the substrate, the through-hole protrusion, the sealing protrusion, the T-shaped block, the arc-shaped strip groove, the T-shaped groove, and the arc-shaped clamping strip are integrally formed by a plastic plate molding process.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] By setting the arc-shaped clamping strip and the arc-shaped strip groove to be clamped with each other, the vertical limit connection between the two substrates can be realized. Compared with the structure that only the "T" - shaped block and the "T" - shaped groove are clamped for splicing, the vertical direction of the substrate is limited, so that the phenomenon of edge warping of the substrate can be effectively avoided, and the splicing stability of the double-sided concave-convex drainage plate is further improved.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 5 , in the embodiments of the present utility model, a double-sided concave-convex drainage board assembly structure includes a drainage board main body 1 composed of a substrate 101, a through-hole protrusion 102, and a sealing protrusion 103. The through-hole protrusion 102 and the sealing protrusion 103 are respectively fixed to the upper and lower end faces of the substrate 101, and the through-hole protrusion 102 and the sealing protrusion 103 are distributed in a staggered matrix. T-shaped blocks 2 are fixedly connected to two adjacent edges of the substrate 101, and T-shaped grooves 4 are opened at the bottoms of the other two adjacent edges of the substrate 101. The T-shaped blocks 2 and the T-shaped grooves 4 are symmetrically distributed with respect to the center of the substrate 101;

[0022] When two drainage board main bodies 1 are spliced, the T-shaped blocks 2 are clamped inside the T-shaped grooves 4 to realize the horizontal limit of the two drainage board main bodies 1;

[0023] An arc-shaped strip-shaped card slot 3 is opened on the side surface of the edge of the substrate 101 connected to the T-shaped block 2, and arc-shaped card strips 5 are fixedly connected to the other two adjacent edges corresponding to the positions of the T-shaped grooves 4 of the substrate 101. The arc-shaped card strips 5 are clamped inside the arc-shaped strip-shaped card slot 3 to realize the vertical limit of the two drainage board main bodies 1.

[0024] In this embodiment: When this double-sided concave-convex drainage board is spliced, the T-shaped groove 4 on one substrate 101 is clamped on the T-shaped block 2 on the other substrate 101, so as to realize the horizontal limit connection between the two substrates 101;

[0025] Meanwhile, when the two substrates 101 are spliced, the arc-shaped card strips 5 will be mutually extruded when they contact the other substrate 101, and the arc-shaped card strips 5 and the other substrate 101 will deform and shrink mutually, so that the arc-shaped card strips 5 can continue to move downward. When the arc-shaped card strips 5 are aligned with the arc-shaped strip-shaped card slot 3, the arc-shaped card strips 5 and the other substrate 101 are reset under the elastic action of their own materials, and the arc-shaped card strips 5 and the arc-shaped strip-shaped card slot 3 are mutually clamped, and then the vertical limit connection between the two substrates 101 is realized;

[0026] Through the cooperation of the above-mentioned multiple parts, the rapid assembly operation of the double-sided concave-convex drainage plate can be realized. Moreover, compared with the structure that only uses the "T"-shaped block and the "T"-shaped groove for clamping and splicing, the vertical direction of the substrate 101 is limited, so that the phenomenon of the edge of the substrate 101 warping up can be effectively avoided, and the splicing stability of the double-sided concave-convex drainage plate is further improved.

[0027] Please refer specifically to Figures 1 to 5 , the bottom surface of the "T"-shaped block 2 is flush with the lower surface of the substrate 101, and the outer wall size of the "T"-shaped block 2 matches the inner wall size of the "T"-shaped groove 4;

[0028] The arc-shaped strip-shaped card slot 3 is located above the "T"-shaped block 2, and the arc-shaped card strip 5 is located above the "T"-shaped groove 4. The outer wall size of the arc-shaped card strip 5 matches the inner wall size of the arc-shaped strip-shaped card slot 3.

[0029] In this embodiment: through this structure, after two double-sided concave-convex drainage plates are spliced, they can be kept in a tightly connected state with each other, and the clamping structure of the arc-shaped card strip 5 and the arc-shaped strip-shaped card slot 3 can also improve the splicing tightness between the two substrates 101.

[0030] Please refer specifically to Figures 1 to 5 , the substrate 101, the through-hole protrusion 102, the sealing protrusion 103, the "T"-shaped block 2, the arc-shaped strip-shaped card slot 3, the "T"-shaped groove 4, and the arc-shaped card strip 5 are integrally formed by a plastic plate molding process.

[0031] In this embodiment: the entire double-sided concave-convex drainage plate is integrally formed by a plastic plate molding process. The same as the traditional production process, no additional steps are added, and the production can be improved on the basis of the original equipment, thus facilitating popularization and production.

[0032] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
