BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection structure between a waterproof pan on a bathtub side and a waterproof pan on a washroom side of a bathroom unit.

[0002]

2. Description of the Related Art As is well known, a bathtub-side waterproof pan in which a bathtub is installed and a washroom-side waterproof pan are installed at the bottom of a bathroom unit. , If you focus only on water tightness,
It is desirable to integrally form the bathtub-side waterproof pan and the washroom-side waterproofpan. However, in consideration of workability, it is desirable to divide the bathtub-side waterproofpan and the washroom-side waterproofpan.

In the case where the bathtub-side waterproof pan and the washroom-side waterproof pan are divided into two parts, the watertightness at the junction of the two waterproof pans becomes important. As a connection structure between the bread and the washing place side waterproof pan, for example, a structure shown in FIGS. 5 and 6 is known.

That is, a conventional bathtub-side waterproof pan 1 shown in FIG.
The connection structure between the washing tub side waterproof pan 2 and the washing tub side waterproof pan 1 is formed by raising the washing tub side waterproof pan 1 of the bathtub side waterproof pan 1 having a substantially inverted J-shaped cross section up to the slope L of a wall panel (not shown). On the other hand, while forming, the bathtub-side facing flange portion 4 of the washroom-side waterproof pan 2 is formed lower than the above-mentioned slope L, and the shelf portion 5 horizontally extended from the upper end of the bathtub-side facing flange portion 4 to the bathtub side. After the lower end of the washing side facing flange 3 is placed on the shelf 5 via the packing material 6, the two facing flanges 3 and 4 are connected to the upper surface of the washing side facing flange 3 and the bathtub side. A screw 8 is screwed into and connected to a metal fitting 7 provided between the facing flange 4 and the shelf 5.

However, in the conventional connection structure between the bathtub-side waterproof pan 1 and the washing-site-side waterproof pan 2, the shelf 5 of the washing-site-side waterproof pan 2 is formed lower than the above-mentioned slope L. However, when a BL standard test is performed in which water is collected up to the above-described slope L and a water tightness test is performed, there is a high possibility of water leakage, and it is difficult to clear the BL standard. I was

A conventional bathtub-side waterproof pan 1 shown in FIG.
The connection structure between the washing tub side waterproof pan 2 and the washing tub side waterproof pan 2 is formed such that the bathtub side facing flange portion 14 of the washing yard side waterproof pan 2 formed in a substantially inverted J-shaped cross section is lower than the above-mentioned slope L. 1 is formed at a height lower than that of the bathtub-side facing flange portion 14 and at the tip of the upper end of the washing-site-side facing flange portion 13 formed in a substantially inverted J-shaped cross section. Connection groove 15 having a substantially concave cross section
Is formed, and the lower end of the bathtub-side facing flange portion 14 is
It is configured such that water-tightness is ensured by dropping it into the connection groove 15 of the washing-place-side facing flange 13 filled with the sealing material 16.

However, even in the conventional connection structure between the bathtub-side waterproof pan 1 and the washing-place-side waterproof pan 2, the washing-bath-side facing flange portion 13 and the bathtub-side facing flange portion 14 of the bathtub-side waterproof pan 1 have the above-described structure. Since it is formed lower than the slope L, when water is collected up to the above-mentioned slope L and the BL standard inspection is performed for water tightness inspection, the possibility of water leakage is high, and the BL standard is cleared. In addition to a structure that is difficult to achieve, the structure is designed to ensure watertightness only with the sealing material 16, and thus has a problem that water leaks easily.

The present invention has been made in view of the above-mentioned situation, and the purpose is to eliminate the possibility of water leakage even by the BL standard inspection in which water is collected up to the slope and the watertightness is inspected. Another object of the present invention is to provide a connection structure of a bathroom waterproof pan with excellent watertightness, which can easily meet the above BL standard.

[0009]

Means for Solving the Problems In order to achieve the above object, in the connection structure of a bathroom waterproof pan according to the present invention,
The opposed flange portions of the bathtub-side waterproof pan and the washroom-side waterproof pan are raised up to the wall surface and formed at the same height, and the opposed flange portion of one waterproof pan is formed in a substantially inverted J-shaped cross section. Further, at the lower end of the opposite flange portion of the other waterproof pan formed in a substantially inverted J-shaped cross section, a receiving portion continuously formed in a substantially concave cross section is formed, and the other waterproof pan of the other waterproof pan is formed. At both ends of the opposed flange portion, a positioning step is formed, and at both ends of the one waterproof pan, cutouts that are dropped into the step and positioned are formed, The notches formed at both ends of the facing flange portion of the one waterproof pan are dropped and placed on the steps formed on the other waterproof pan, so that the facing flange portion of one waterproof pan is waterproofed by the other. Shaped on the opposite flange of the pan The receiving portion that is, with each opposing flange portions are connected so as to be held on the slopes same height as the wall panels, it is characterized in that the concatenation of these two opposing flanges with fittings.
