DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof pan for a bathroom,
In particular, the present invention relates to a split type waterproof pan in which a bath tub mounting pan and a washing pan are separated.

[0002]

2. Description of the Related Art A conventional example of this type of split type waterproof pan is disclosed in Japanese Patent Application Laid-Open No. 1-235737.

[0003] The waterproof pan in the bathroom of the same type comprises a separate bathtub placing pan 1 and a washing pan 2 connected side by side as shown in Figs. An engaging recess 3 is provided at an edge of the bathtub mounting pan 1, and an engaging piece 4 composed of a hanging piece of the washing pan 2 is engaged with the engaging recess 3 from above. 3 is filled with a waterproof material 5 to provide waterproofing.

[0004] As shown in FIG.
In No. 37, the drain trap 6 is provided only on the bathtub mounting pan 1. The drainage trap 6 is provided so as to protrude from the bathtub placing pan 1 in order to easily receive the drainage of the washing pan 2, and the washing pan 2 has a rectangular bite for receiving the drain trap 6. Part is provided.

[0005]

However, the conventional bathroom waterproof pan has the following problems.

Since the drain trap is provided only in the bathtub mounting pan 1, water is transferred from the washing pan 2 to the bathtub mounting pan 1 so as to cross the seam between the bathtub mounting pan 1 and the washing pan 2. Flows. For this reason, water will be splashed on the seams of the breads 1 and 2, which will easily cause water leakage.

[0007] Since the joint between the bathtub placing pan 1 and the washing pan 2 is sealed only by the waterproof material 5, the waterproof property is insufficient and water leakage is likely to occur.

[0008] The shape of the bread is complicated, and the moldability of the FRP bread is not good.

The pans 1 and 2 are connected by the engagement of the engagement recess 3 and the engagement piece 4, and the connection strength of the pans 1 and 2 is low, and the integrity is poor.

[0010]

According to a first aspect of the present invention, there is provided a waterproof pan for a bathroom in which a separate bathtub mounting pan and a washing pan are connected side by side. A drain trap is provided on both the placing pan and the washing pan, a working port for underfloor work is provided on the bathtub placing pan, and a rising edge is provided along a side edge of the bathtub placing pan and a side edge of the washing pan. The side edges are butted together via a packing, and these breads are connected by screws, and caulking is performed on the upper side of the packing of the butting surfaces of the breads. It is.

The waterproof pan for a bathroom according to the second aspect is the waterproof pan for a bathroom according to the first aspect, wherein the abutting portions of the bath tub placing pan and the washing pan have an inverted U-shaped vertical cross-sectional shape, respectively. A backup member is inserted into the inverted U-shaped portion of the bread, and the screw is driven from the bathtub mounting pan side to the washing pan side, and the screw is a backup material on the bathtub mounting pan side. , And the tip of the screw is screwed into a backup material on the side of the washing pan.

[0012]

The waterproof pan in the bathroom according to the present invention is integrated by juxtaposing the bath tub placing pan and the washing pan in abutment and connecting them with screws.

In this case, first, the washing pan is carried into the bathroom and installed, and the level of the washing pan is adjusted from the side of the empty bathtub. Next, the bath tub mounting pan is carried into the bathroom and set therein, and the level of the bath tub mounting pan is adjusted through the working port. Then, both breads are connected with screws.

[0014] In the waterproof pan of the second aspect of the present invention, since the backup material is disposed at the joint edge of both pans, the screw works well and the joint strength between the pans is high.

[0015]
