Description

TECHNICAL FIELD The present invention relates to a shower room unit using a wash pan for a bathroom unit, and an under-wall angle member.

In recent years, with the increase in the number of foreign tourists, there is a growing demand for shower rooms without bathtubs at lodging facilities.
Moreover, in Japan, the number of young people and singles who wash their bodies daily only by taking a shower tends to increase.
In addition to the above reasons, it is thought that the need for shower rooms will continue to increase in small apartments in metropolitan areas, including effective use of indoor space and cost reduction.

Conventionally, floor pans for bathroom units have generally been divided into a washing space pan used as a washing place and a bathtub pan for installing a bathtub, for the purpose of improving portability at the site. (See Patent Document 1)

Also, the washing area pan and the bathtub pan are each manufactured in a factory, transported to the site, and then joined to each other at the site to be integrated with a waterproof structure. After that, wall panels and doors are erected on the outer periphery of the integrated floor pan. A ceiling panel is installed on top of the wall panel, and a bathtub, a bathtub apron, a faucet, etc. are attached to complete the bathroom.
An example of a conventional bathroom unit 100 is shown in FIG. A panel 103 is installed. A bathtub 110 is installed on the bathtub pan 124, a bathtub apron 112 is installed between the bathtub 110 and the washing place pan 123, and a faucet 105 is attached to a part of the wall panel 102.例文帳に追加

On the other hand, floor pans for shower room units are manufactured individually because they do not require installation of a bathtub. After installing this floor pan on site, wall panels and doors are erected around its perimeter.
A ceiling panel is installed on top of the wall panel, and a faucet or the like is attached to complete the shower room.
An example of a conventional shower room 131 is shown in FIG. A ceiling panel 133 is installed on the upper part. A shower room 131 is configured by attaching a faucet 135 to a part of the wall panel 132, connecting a shower hose 136 and a shower head 137 to the faucet 135, and installing a mirror 138 at a required position on the wall panel 132. ing.
Conventionally, the wash area pan for bathroom units and the floor pan for shower room units differ in the shape of the outer periphery (especially the bathtub pan fitting portion of the wash area pan for bathroom units), so each is designed and manufactured separately as a dedicated member. and installed.

"Third Embodiment"
As shown in FIG. 5, when used for the bathroom unit 100, the conventional wash pan 123 secures the strength around the drain port while being connected to the bathtub pan 124 and the bathtub apron 112. As shown in FIG.
However, when applying the floor pan 11 to the shower room unit 1, the floor pan 11 is used alone. In this case, the legs 30 for the floor pan 11 are provided one by one near the four corners of the bottom surface of the bottom wall 11a, a total of four.

If the number of legs 30 of the shower room unit 1 is four, the strength of the floor pan 11 is lowered. For example, if the user gets on the drain port 12 or its vicinity and the user's weight is applied to the floor pan 11, the amount of deformation of the sinking of the floor pan 11 increases, causing discomfort to the user, and furthermore, the connection This may lead to water leakage from the drain trap 17 and the drain pipe 18 that are installed.

As shown in FIG. 1(c), the legs 30, when viewed from the bottom surface of the floor pan 11, are positioned on the side of the bathtub pan fitting portion 20 by the amount of the bathtub pan fitting portion 20 provided. , too much inward and unbalanced.
With this configuration, if the worker puts his or her foot on the bathtub pan fitting portion 20 and applies the weight of the floor pan 1 during construction (before the wall panel 2 is erected), the floor pan 1 will be lifted by the principle of leverage. Problems such as floating on the opposite side of the floor pan 11 and movement of the installation position of the floor pan 11 may occur.

Therefore, in the floor pan 11 of this embodiment, an auxiliary leg 31 is attached to the lower surface of the bathtub pan fitting portion 20 . The auxiliary leg 31 is desirably constructed so that its length can be adjusted using a screw shaft and a bearing, etc., and is erected on the outdoor side as shown in FIG. 1(b).
By providing the auxiliary legs 31, the amount of deformation of the floor pan 11 can be suppressed, and the lifting of the floor pan 11 during construction can also be suppressed.
By attaching the auxiliary leg 31 to the bathtub pan fitting part 20, when connecting the drain pipe 18 to the drain trap 17, as shown in FIG. Therefore, the selection range of the drainage route at the site becomes diverse.

Further, when the auxiliary leg 31 is attached to the bathtub pan fitting portion 20, when the drain port 12 provided in the floor pan 11 is arranged in the longitudinal direction central side of the bank 21 and in the vicinity of the bank 21, the following positions are used. Auxiliary legs 31 are preferably attached.
The mounting position of the auxiliary leg 31 is on the back side of the bathtub pan fitting portion 20, and is 1/4 to 1/4 of the total length (entire width) of the bathtub pan fitting portion 20 from the longitudinal end of the bathtub pan fitting portion 20. It is preferable to attach the auxiliary leg 31 to a position within the range of 2/5.

By attaching the auxiliary legs 31 in this range, even if the user puts his or her weight on the vicinity of the drain port 12, the amount of deformation of the floor pan 11 can be further reduced, and the floating of the floor pan 11 can be prevented. It is possible to prevent positional displacement when installing the floor pan 11. - 特許庁
Also, when the auxiliary leg 31 is viewed from the direction shown in FIG. 1(b), the auxiliary leg 31 is at a position sandwiching the drain trap 17 with other adjacent legs 30, and when viewed from the direction shown in FIG. As can be seen, the area near the drain trap 17 is supported more than the other legs 30, so the provision of one auxiliary leg 31 enables the floor pan 11 to be supported more stably.
