[Industrial applications]

 The present invention relates to a combination unit of a bathtub and a waterproof pan, which includes a waterproof pan having a wash floor and a bathtub fitting hole, and a bathtub fitted into the bath pan fitting hole of the waterproof pan.

[0002]

[Prior art]

 As a conventional combination unit of a bathtub and a waterproof pan, for example, there is a bathroom unit described in JP-B-57-43250. FIG. 5 is a perspective view of the bathroom unit, and FIG. 6 is a sectional view of the bathroom unit. 7 and 8 are enlarged cross-sectional views of the portion where the bathtub is fitted into the bathtub fitting hole.

The waterproof pan 1 is made of glass fiber reinforced plastic (FRP), and has a wash floor 2 and a bathtub fitting hole 3 formed therein. Then, a bathtub 4 made of FRP or stainless steel or the like can be fitted into the bathtub fitting hole 3 to form a bathroom part having the bathtub 4, the washing floor part 2 and the waist wall part 5. The purpose is to be able to easily construct a completely waterproof bathroom.

Next, the configuration of the portion where the bathtub 4 is fitted in the bathtub fitting hole 3 will be described.

As shown in FIGS. 6 and 7, in the fitting configuration on the side of the washing floor 2, the rising wall 6 is formed around the bathtub fitting hole 3 of the waterproof pan 1 and the rising wall 6 is formed. Next, the side wall surface 5a continues downward from the substantially horizontal horizontal wall 10 to the wash floor 2. The upper part of the peripheral wall of the bathtub 4 forms an upper surface portion 7 that spreads outward, and the edge of the upper surface portion 7 is bent downward to form a vertical surface portion 8. The bathtub 4 is fitted into the bathtub fitting hole 3 from above. The lower surface of the upper surface portion 7 of the bathtub 4 is adapted to ride on the top portion of the rising wall 6 of the waterproof pan 1.

In order to prevent water leakage from the portion where the bathtub 4 is fitted into the bathtub fitting hole 3, as shown in FIG. 7, for example, the bottom surface of the top surface portion 7 of the bathtub 4 and the rising of the waterproof pan 1 are raised. The bathtub 4 is placed with an elastic packing material 9 having watertightness interposed between it and the top of the wall 6.

[0007] Furthermore, in the gap between the substantially horizontal horizontal wall 10 formed at the base of the rising wall 6 in the peripheral portion of the bathtub insertion hole 3 of the waterproof pan 1 and the lower end edge of the vertical surface portion 8 of the bathtub 4, waterproof bullets are used. In some cases, the caulking material 11 is embedded.

As shown in FIG. 8, in the wall-side fitting configuration, a rising wall 6 is formed in the peripheral portion of the bathtub fitting hole 3 of the waterproof pan 1, and a substantially horizontal lateral wall 10 following the rising wall 6 is formed. The side wall surface 5b continues from above to connect to a wall material (not shown).

[0009] Even with the above-mentioned configuration, water and water drips from the wall surface material of the bathroom and the like drips into 10 parts of the groove-shaped lateral wall, and the lateral wall 10 of the waterproof pan 1 is fitted in the fitting part on the wall side of the bathroom. It is impossible to embed the elastic caulking material for waterproofing in the gap between the lower end edge of the vertical surface portion 8 of the bathtub 4 and the bottom edge. Therefore, not only is the elastic packing material 9 installed on the top of the rising wall 6, but also between the lateral wall 10 at the base of the rising wall 6 of the waterproof pan 1 and the lower surface of the upper surface portion 7 of the bathtub 4 the upper and lower edges of the frame body. There is also an example in which a watertight frame 12 with a packing material attached is attached to completely prevent leakage.

[0010]

[Problems to be solved by the device]

 However, in the conventional combination unit of the bathtub and the waterproof pan such as the bathroom unit, when the hot water is put into the bath tank 4 due to the structure of the watertightness and the characteristics of the elastic packing material attached, It became heavier and strongly compressed the elastic packing material to exert a watertight effect, and at the same time, the bathtub slightly sinked, and when the hot and cold water in the bathtub was discharged, the bathtub 4 became lighter and slightly lifted by the elastic packing material.

Due to the load fluctuation and vertical movement of the bathtub occurring as described above, the horizontal wall 10 of the waterproof pan 1 and the lower end edge of the vertical surface portion 8 of the bathtub 4 come into contact with each other to make an abnormal noise. There is a problem that the FRP itself causes discomfort and anxiety because it tends to produce squeak noise.

Further, in the example in which the elastic caulking material 11 is embedded for waterproofing in the gap between the lower end edge of the vertical surface portion 8 of the bathtub 4 and the lateral wall 10 of the waterproof pan 1, caustic noise is reduced by caulking. However, there are cases where caulking is difficult and difficult and requires a lot of time. There are also problems that the appearance of the caulking material is impaired due to stains and mold, and it is necessary to remove the caulking material during maintenance work.

In addition, in the case of using the watertight frame 12, there is a problem that the cost is increased in addition to the above problem.

Each of the above problems is caused by the rising wall 6 and the lateral wall 10 in the peripheral portion of the bathtub fitting hole 3 of the waterproof pan 1 and the side wall surface continuing upward as in the example of the wall surface side of the bathroom shown in FIG. In the structural portion where the groove-shaped depression is formed by 5b, if the waterproofness of the bathtub fitting hole 3 portion is not perfect, it will cause serious problems such as adversely affecting the building frame. Moreover, since the walls are close to each other for waterproofing the same part, construction is difficult and caulking is also impossible.

This invention has been made in order to solve the above-mentioned problems of the prior art, and has a recessed portion around the bathtub fitting hole such as the wall surface side of the bathroom, etc., which makes it difficult to perform watertight construction. Even in the structured part, the watertightness between the waterproof pan and the bathtub can be improved, construction can be performed easily, and the bathtub and waterproofing that prevent the generation of noise causing discomfort or anxiety It is intended to provide a combination unit of bread.
