[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joining structure of a rising member of a waterproof pan, and more particularly, to a structure for preventing a step from being formed in a joining region between rising members and improving the waterproofness of the joining region. The present invention relates to a joining structure of a rising member of a waterproof pan that can be achieved.

[0002]

2. Description of the Related Art In recent years, system bathrooms in which a bathroom and a washroom adjacent to the bathroom are integrated into a unit have become widespread. For the floor surfaces of these bathrooms and washrooms, for example, a bottomed box-shaped resin waterproof pan having an open top as shown in each of FIGS. 12A to 12C is used. The waterproof pan 80 includes a floor forming plate 81 that forms a floor surface of a washroom or the like, and a floor forming plate 81 that forms the floor.
And a separate rising member 82 erected in the outer peripheral area of the main body. Here, the waterproof pan 80 shown in FIG. 9A is cut so that the end surface 82A of the rising member 82 is at 45 degrees with respect to the outer surface 82C, and is disposed substantially at a right angle in the corner region of the waterproof pan 80. The joining between the raised members 82 is performed by abutting the end faces 82A. Also, FIG.
The joining of the corner area of the waterproof pan 80 shown in FIG.
This is performed by joining the end surface 82A of the other rising member 82 to the inner surface 82B of one rising member 82. The waterproof pan 80 shown in FIG.
A curved concave portion 86 is formed on an inner surface 82B of the rising member 82.

However, such a rising member 82
In the joint structure of (1), the contact area between the rising members 82 cannot be made larger than the area corresponding to the area of the end face 82A, and the waterproofness of the region where the rising members 82 are joined is sufficiently improved. There is a disadvantage that it cannot be secured. In particular, as shown in FIG. 12C, in the joining between the rising members 82 having the curved concave portions 86 formed therein, cavities H due to the curved concave portions 86 are generated in these joint regions. The waterproofness of the joint area is further deteriorated.

Therefore, in order to prevent water leakage from the cavity H due to the curved concave portion 86, for example, as shown in FIG. 13, a rising member 92 in which the cavity H is not generated in a joined state is known. . This rising member 90 is
On its inner surface, a linear member 92 is disposed in the outer peripheral linear region of the floor forming plate 81 described above, and a corner member 93 is disposed in an outer peripheral corner region of the floor forming plate 81. Here, the joining of the linear member 92 and the corner member 93 is performed by butting their end faces 92A and 93A mutually.

[0005]

However, in the rising member 90, since the joining between the linear member 92 and the corner member 93 is performed by abutting the end surfaces 92A, 93A, the end surface 92A is formed.
Alternatively, the contact area cannot be larger than the area of the end face 93A, and similar to the case of FIG.
There is an inconvenience that sufficient waterproofness cannot be ensured in the joint area between the straight member 92 and the corner member 93.

Meanwhile, as shown in FIGS. 14A and 14B, there is known a rising member 95 provided so as to sufficiently secure waterproofness of a joint area. The rising member 95 is connected to the floor surface forming plate 81 (FIG. 12A).
A linear member 96 arranged in the outer peripheral linear region of
And a corner member 97 arranged in an outer peripheral corner region of the floor surface forming plate 81. The joining of the straight member 96 and the corner member 97 is performed by accommodating a region on the end surface 96A side of the straight member 96 in an inner region 97A of the corner member 97.

However, in the rising member 95, the linear member 96 and the corner member 97 are joined by the region on the end surface 96A side of the linear member 96 being accommodated in the internal region 97A of the corner member 97. Therefore, as shown in FIG. 14B, a step S is generated in the joining region. When the wall panel or the like (not shown) is installed on the upper surface side of the rising member 95, the step S not only causes an obstacle but also causes inconvenience of impairing the appearance of a corner area such as a washroom. .

[0008]

SUMMARY OF THE INVENTION The present invention was devised in view of such inconvenience, and an object of the present invention is to reduce the waterproofness of the joining region without causing a step in the joining region between the rising members. An object of the present invention is to provide a joint structure of a rising member of a waterproof pan that can be improved.
