Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor structure of a bathroom unit which is an assembling bathroom.

[0002]

2. Description of the Related Art Unit baths, which are prefabricated bathrooms, are:
First, a waterproof floor is installed at a place where the unit is installed, and a wall panel is built on the outermost wall mounting surface to form a room. Of these unit bath applications, in the case of condominiums and other condominiums, which are installed for condominiums, in recent years, due to the structure of the building, exposed beams or inverted beams protruding from the waterproof floor installation location often occur, and In response to the increasing demand for step reduction for elderly people, the number of sites that want to install waterproof floors as low as possible has increased, and the danger of interference between exposed beams and waterproof floors has been increasing. It is much larger than that. That is, the lower the floor is installed to reduce the level difference, the more easily the exposed beams and the back surface of the waterproof floor of the unit bath interfere with each other, and the waterproof floor cannot be installed at a predetermined position and height. It is easy to happen.

[0003] In order to be able to install a waterproof floor at a predetermined position even if such a beam is generated, a waterproof floor of a recent unit bath has a floor support leg position as far as possible inside the outer periphery of the floor. In addition, measures to reduce the protrusion of reinforcement on the back surface of the floor pan will be applied to the outer peripheral part where exposed beams may be generated, so that the exposed beams with the largest dimensions can be released without interference Have been.

As described above, the wall panel of the bathroom unit is placed on the outermost peripheral wall of the floor, and the weight of the wall is
Loaded on the outer periphery of the floor. Ideally, the load on the wall is to be supported by the floor support legs provided directly below it, but the floor support legs must be placed inside the outer periphery of the floor to avoid exposed beams, and the wall load Can not be supported directly under such a position. As a result, the waterproof floor body must support the wall load in a state where the distance from the floor support position to the wall mounting surface where the actual load is applied is large,
If the strength of the waterproof floor is not further improved because the moment due to the load increases, deflection and deformation due to the wall weight may increase. There has been a problem of circumnavigating that the size of the protrusion hinders the dimension of the exposed beam that can be avoided. In addition, as for the exposed beam, since there is no quantitative object of what size is generated, it is not perfect to avoid it no matter how much it is avoided, but it is advantageous to be able to avoid it more greatly in terms of fitting conditions Therefore, studies are being continued so that even a little can be avoided.

[0005]

SUMMARY OF THE INVENTION In view of the above, the present invention reduces the size of the protrusion on the back surface of the floor while improving the strength of the floor. It is an object of the present invention to provide a unit bath having a floor structure with good fit conditions that can be accommodated.

[0006]

According to the first aspect of the present invention, there is provided a waterproof floor provided with a bathtub mounting portion, a wall panel constituting a wall portion, and a waterproof panel mounted on the wall panel. In a bathroom unit including a ceiling panel to be mounted and fixed, a reinforcing shape that is exposed to the interior of the bathroom is formed on a floor between a floor on which the bathtub is mounted and a rear surface of the bathtub body.

According to the present invention, the strength of the floor can be increased while reducing the protrusion on the back surface of the waterproof floor, so that a larger exposed beam can be avoided.

The second aspect of the present invention is the first aspect.
In the case of the invention described, the floor reinforcement shape of the bathroom unit is arranged in a direction orthogonal to an outer peripheral side of the floor on which the bathtub is installed.

According to the present invention, since the applied reinforcing shape can efficiently receive the weight of the wall panel mounted on the outermost peripheral portion of the waterproof floor, the reinforcing shape can be reduced to a small dimension, and the reinforcing panel is installed indoors. In addition to reducing the possibility of interference with appliances and the bottom and side surfaces of the bathtub, the pan capacity of the bathtub-side floor is not reduced. In addition, since the direction is such that it does not easily interfere with the drainage gradient of the floor on the bathtub side, a space closed by the reinforcing shape is less likely to occur, and it is easy to ensure the drainage of the bathtub side floor pan.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view of a bathroom showing an example of a floor structure according to the present invention. The bathroom Y includes a waterproof floor A, a wall panel 1 and a ceiling panel (not shown) placed on the outer periphery thereof, a fitting 2 forming an entrance, and the like.

The waterproof floor A forms a floor of a bathroom, and is integrally formed of a resin material such as FRP by resin molding using a molding die.

A wall mounting surface 3 for mounting a wall is formed all around the outer peripheral portion of the waterproof floor A. The waterproof floor A is a washing-side floor 4 forming a washing scene and a bathtub-side floor 5 adjacent thereto.
It is composed of A bathtub 6 is installed on the bathtub side floor 5. At this time, the bathtub side floor 5 is installed by dropping the bathtub 6 so that the height H of the bathtub crossing can be kept low. It is formed by digging lower. Naturally, the bathtub-side floor 5 also has a smaller clearance between the floor back and the building frame 7.

A drain port 8 is formed in the bathtub side floor 5 to drain the hot water flowing into this part to the outside, as shown in FIG. 2, and a drain gradient is taken toward the drain port 8. Water that flows in is collected and drained.

The floor support legs 9 of the waterproof floor A for supporting the weight of the bathroom Y are installed so as to avoid interference as much as possible even when the building frame 7 has the exposed beams 701. The outer peripheral portion 501 of the bathtub-side floor 5 that is dug down and formed low also has a shape that is released to the upper part so as to avoid the exposed beam 701 as much as possible.

A back reinforcement 10 is provided on the back surface of the waterproof floor A to support the entire weight of the bathroom Y. Similarly, a back reinforcement 101 is formed on the outer periphery of the floor to support the weight of the wall panel 1. Have been. Usually, these back reinforcements 101 are formed in a shape protruding greatly to the back as shown in FIG. 7 in order to support the weight of the wall panel 1 placed on the wall placement surface 3 at the outer periphery of the floor. When the exposed beam 701 is generated on the skeleton side, the back reinforcement 101 particularly at this portion easily interferes.

In the present invention, as shown in FIGS. 2 and 4, the back reinforcement 101 of the bathtub-side floor outer peripheral portion 501, which has a high risk of interfering with the exposed beam 701, is used as the exposed back beam.
1 is formed not only on the floor back side where there is a high possibility of interference with the floor 1 but also on the floor front side between the bathtub body and the back, thereby suppressing protrusion on the floor back and avoiding interference with the exposed beam 701. By maintaining the same second moment of area, the strength is ensured, and a problem such as interference is unlikely to occur.

The reinforcing shape on the floor surface side includes a thin rib shape 102 as shown in FIG. 3 and a convex frame shape 103 as shown in FIG. 5, and the like. It is formed in a direction perpendicular to the direction. It should be noted that what is shown is an example, and any other shapes can be used as long as the reinforcement is effective.

Further, these reinforcing shapes 102, 103
Has a size that does not interfere with the back surface of the bathtub 6 installed on the bathtub-side floor 5 and is formed only in the required places, so that the floor capacity of the bathtub-side floor 5 is secured without unnecessarily reducing the pan capacity. Effective reinforcement of the floor is possible while keeping it. The pan capacity of the bathtub side floor 5 may be determined when the bather suddenly immerses the bathtub 6 in a full bath, such as when a large amount of hot water is used in the bathroom Y,
Because it is used as a buffer tank in case of an emergency such as a water leak accident, the larger one has a higher capacity and a safer floor.

[0020]

The present invention has the following effects. According to the invention described in claim 1 of the present invention, a waterproof floor having a bathtub mounting portion, a wall panel forming a wall portion,
In the bathroom unit composed of a ceiling panel mounted and fixed on the wall panel, a reinforcing shape exposed to the inside of the bathroom is formed on the floor between the floor on which the bathtub is mounted and the back of the bathtub body. In addition, the size of the reinforcement projecting from the floor back can be reduced, and exposed beams can be effectively avoided while securing sufficient floor strength. With this structure, it is possible to provide a floor with better fit conditions than conventional products without sacrificing floor strength.

The second aspect of the present invention is the first aspect.
In the case of the invention described in the above, since the floor reinforcement shape of the bathroom unit is arranged in a direction orthogonal to the outer peripheral side of the bathtub installation side floor, it efficiently receives the wall load applied to the outer peripheral portion of the floor. As a result, the size of the reinforcing shape can be reduced, the risk of interference with other appliances in the bathroom can be reduced, and the pan capacity of the bathtub side floor can be easily secured. Is arranged in a direction that does not interfere with the water gradient of the bathtub-side floor, so that a sanitary structure that does not generate pool water can be provided.
