Abstract

PROBLEM TO BE SOLVED: To provide a new product called "a board for leakage prevention" and capable of being used for an arbitrary location such as a floor board, a wall surface and a ceiling surface.SOLUTION: A waterproof sheet material 1, in which adhesion coating layers 4 and 5 are interposed on both sides, is lap-bonded between plate-like materials 2 and 3 constituting front and back sides of a board. Lengthwise edges of the plate-like materials 2 and 3 are positioned in the state of being displaced from each other so as not to overlap each other.SELECTED DRAWING: Figure 1

Description

The present invention relates to a water leakage prevention board that can be used at any place such as a floor plate, a wall surface, a ceiling surface.

Conventionally, as a waterproof board, there is a board formed by forming a decorative sheet having a surface impermeable to moisture on the surface of a single plate (see, for example, Patent Document 1).

JP 2003-184287 A

The conventional means as described above has a good waterproof effect from the surface side. However, when moisture, water leakage, or the like is applied from the back side, the adhesive layer of the decorative sheet may be eroded and destroyed. That is, the waterproof property from the front side is good, but the resistance against the moisture atmosphere from the back side is extremely weak.

The present invention is intended to provide a new product called a “water leakage prevention board” that solves such problems.

As described in claim 1, the present invention uses a plate-like material formed by connecting a plurality of sheets as a plate-like material that controls the front side and the back side of the board, and an adhesive is applied between both sides of the plate-like material. The waterproof sheet material is polymerized and bonded with a layer interposed, and both the front and back side plate-like materials are positioned so as to be shifted from each other so that the edges of the front and back surfaces do not overlap. Related to water leakage prevention board.

According to a second aspect of the present invention, there is provided a reinforcing sheet material made of a cloth material or a net material having a rough enough to allow the adhesive to penetrate on the inner surface side or outer surface side of the adhesive coating layer. The water leakage prevention board according to claim 1, which is interposed, is an embodiment.

The present invention is based on the use of the structure as set forth in claim 1, that is, a waterproof sheet in which adhesive coating layers 4 and 5 are interposed on both sides between the plate-like materials 2 and 3 constituting the front and back of the board. Since the material 1 is configured to be polymerized and bonded, the water leakage prevention effect is achieved by the waterproof sheet material 1 located in the center, and the waterproof sheet material is applied to both plate-like materials located on the front and back sides. It will have a waterproof effect.

Therefore, the manufacturing cost can be reduced as compared with the case where the waterproof function is provided separately for the front and back sides. Further, it is well prevented that moisture or water from one side affects the other side.

Furthermore, since the plate-like materials 2 and 3 are arranged so as to be shifted from each other so that the edges of those located on the front and back do not overlap, the strength weakness of the adjacent edge portions of each other ( The strength weak point that it is easy to bend) is received and reinforced by the plate surface portion of the other plate-like body, and the overall robustness is maintained.

The present invention is based on the use of the structure as described in claim 2, and the overall reinforcing effect is increased and the remarkable robustness is maintained.

It is a partially cutaway perspective view for explanation of the present invention. It is an expanded sectional view of the present invention. It is a partially cutaway perspective view for explanation showing another embodiment of the present invention.

In the figure, reference numeral 1 denotes a waterproof sheet material, which is preferably made of a material having toughness and water shielding properties such as a synthetic resin sheet.

2 and 3 are plate-like materials forming the front and back of the board, which are made of any plate-like material such as wood, PP material, metal material, etc., and are configured so that the required number is linked in the length direction. .

Reference numerals 4 and 5 denote adhesive coating layers, which are formed on the respective inner surfaces of the plate-like material, that is, on both surfaces of the waterproof sheet material. As a result, the plate-like materials 2 and 3 are firmly superposed and bonded to both surfaces of the waterproof sheet material 1. An asphalt material may be used as the adhesive, and a colloidal (non-solidified) adhesive material that does not solidify may be used.

Furthermore, when carrying out by interposing a reinforcing sheet material 6 made of a cloth material or a net material having rough enough to allow the adhesive to permeate, on the inner surface side or outer surface side of the adhesive coating layer (See FIG. 3 for the inner surface side.)

In addition, the plate-like members 2 and 3 forming the front and back described above are configured so as to be positioned in a state of being shifted from each other so that the edges do not overlap (the contour that is the outermost edge). Excluding edges).

In other words, the edge-matching portion of the plate-like material on one side surface is received by the surface of the plate-like material on the other side surface and is prevented from being bent from the matching portion. Accordingly, the strength problem caused by the flexibility of the waterproof sheet material 1 at the center that controls waterproofing is solved, and the overall robustness is maintained.

In addition, although it is the surface arrangement of both plate-like materials on the front and back, this is basically arranged in the length direction, but other than this, it is arranged in the horizontal direction, or in the form of bricks or tiles. It may be configured. Even in this case, it is important that the edge-matching portions of the plate-like materials located on the front and back are shifted.
