Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a waterproof floor pan used for floors of bathrooms, shower rooms, etc.

(Conventional technology) Conventional waterproof floor pans are made of FR, which has excellent waterproofness and strength.
Those made of P (glass fiber reinforced plastic) are common. This FRP waterproof floor pan was made by preparing a mold with a molding surface that corresponds to the inner surface shape of the waterproof floor pan, and spraying FRP onto the molding surface of the mold, laminating it, and cooling and solidifying it. After that, it is extracted from the mold and manufactured.

(Problems to be Solved by the Invention) However, as described above, such conventional waterproof floor pans require a mold as manufacturing equipment, which increases the cost required for manufacturing equipment.

In addition, since the material is limited to FRP, it is not possible to combine multiple colors or change the texture, and in waterproof floor pans with a waist wall built around the floor, the waist Since it is necessary to provide a vertical slope in the wall portion, the shape is also limited, and there is a problem that the degree of freedom in design is extremely limited.

The present invention has focused on the above-mentioned conventional problems, and aims to provide a waterproof floor pan that requires low costs for manufacturing equipment and has a wide degree of freedom in design.

(Means for Solving the Problems) In order to achieve the above object, the waterproof floor pan of the present invention is a waterproof floor pan in which a waist wall section is erected around a floor section, the floor pan and the waist wall section being erected around the floor section. The inner surface of the wall part is made of a plate material, and the outer surfaces of the floor part and the waist wall part are made of a glass fiber reinforced plastic layer that is bonded to the plate materials and laminated on the back surface of the plate material.

(Function) The waterproof floor pan of the present invention can be manufactured by a manufacturing method that does not use a mold, since the inner surfaces of the floor part and the waist wall part are made of plate material. In other words, by applying a manufacturing method that does not use molds, the cost required for manufacturing equipment can be reduced, and it is also possible to manufacture waterproof floor pans with a shape that does not have a slope in the waist wall. This makes it possible to increase the variety of shapes.

In addition, you can freely select the color and material of the board, and you can also combine multiple types of board with different colors and materials, so you can increase the variety of colors and materials.

Further, in the waterproof floor pan of the present invention, since the outer surfaces of the floor part and the waist wall part are constituted by the glass fiber reinforced plastic layer, waterproof performance and strength can be sufficiently maintained.

(Example) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

First, the configuration of this embodiment will be explained based on FIG.

FIG. 1 is a cutaway perspective view showing the waterproof floor pan of this embodiment. This waterproof pan is composed of a floor section 1 and a waist wall section 2 erected around the floor section 1. As shown in FIG. Further, the inner surfaces of the floor section 1 and the waist wall section 2 are constituted by board materials 1a and 2a, and the board materials 1a and 2a have a size that allows each of the inner surfaces of the floor section 1 and the waist wall section 2 to be constructed with one piece. It is formed. Furthermore,
The outer surfaces of the floor portion 1 and the waist wall portion 2 are the plate materials 1a.

It is composed of glass fiber reinforced plastic layers 1b and 2b laminated on the entire back surface of the plate material 2a, and the glass fiber reinforced plastic layers 1b and 2b are
It is also provided on the back side of the joint of the adjacent board 1a.
, 2a are coupled together.

Next, the operation of this embodiment will be explained based on FIGS. 2 and 3.

The waterproof floor pan of this embodiment can be manufactured by a manufacturing method that does not use a mold, since the inner surfaces of the floor part 1 and the waist wall part 2 are constituted by the plate materials 1a and 2a as described above. In other words, by applying a manufacturing method that does not use a mold, the cost required for manufacturing equipment can be reduced, and
It becomes possible to manufacture a waterproof floor pan having a shape in which the waist wall part 2 is not sloped, and variations in shape can be increased.

Furthermore, the plates 1a and 2a may be plastic plates such as FRP plates, wooden plates or stone plates, and the colors and materials of the plates 1a and 2a can be freely selected. Furthermore, it is also possible to combine a plurality of types of board materials with different colors and materials, such as by using a stone board for the floor part 1 and a plastic board for the waist wall part 2. In this way, you can increase the variety of colors and materials.

Further, in the waterproof floor pan of the present invention, the outer surfaces of the floor portion 1 and waist wall portion 2 are constituted by the glass fiber reinforced plastic layers 1b and 2b, so that waterproof performance and strength can be sufficiently maintained.

FIGS. 2 and 3 each show an example of a method for manufacturing the waterproof floor pan without using a mold.

First, FIG. 2 shows a manufacturing method using a framework 3 instead of a mold, and as shown in FIG. 2a constitutes the inner surface shape of the floor part 1 and waist wall part 2, and then (b) of FIG.
As shown in the figure, glass fiber reinforced plastic is sprayed on the back side of each flooring material 1a, 2a so as to combine these flooring materials 1a, 2a, thereby forming glass fiber reinforced plastic layers 1b, 2.
b, this glass fiber reinforced plastic layer 1b,
This is a method in which the framework 3 is disassembled or folded and removed after the solidification of the framework 2b.

Moreover, FIG. 3 shows a manufacturing method using a connecting tool 4 instead of a mold, and as shown in FIG. 2a constitutes the inner surface shape of the floor part 1 and waist wall part 2, and then (b) of FIG.
As shown in FIG. 1, glass fiber reinforced plastic is sprayed onto the back surfaces of the flooring materials 1a and 2a so as to permanently bond these flooring materials 1a and 2a to form a glass fiber reinforced plastic layer 1b.

2b and glass fiber reinforced plastic layers 1b, 2
In this method, the connector 4 is removed after solidification.

In any of these methods, there is no need to use a mold, so the cost of manufacturing equipment can be reduced, and it is possible to manufacture a waterproof floor pan with a shape in which the waist wall part is not sloped. Incidentally, in the above manufacturing method, it is preferable that the framework 3 and the connector 4 are those that can be used repeatedly. By doing so, manufacturing equipment costs can be further reduced.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and even if there are design changes within the scope of the gist of the present invention, they are included in the present invention. It will be done.

For example, in the example, each inner surface of the floor and waist wall was constructed with a single board by using a large board, but each inner surface of the floor and waist wall was constructed using a plurality of smaller boards. It may be constructed from a plate material.

(Effects of the Invention) As explained above, since the waterproof floor pan of the present invention can be manufactured using a manufacturing method that does not use a mold, the cost required for manufacturing equipment can be reduced. . In addition, variations in shape, color, and texture can be increased, and the degree of freedom in design is high, resulting in the ability to respond to various requests.

Moreover, in the waterproof floor pan of the present invention, since the outer surfaces of the floor part and the waist wall part are constituted by the glass fiber reinforced plastic layer, the above-mentioned effects can be obtained while maintaining sufficient waterproof performance and strength.
