A flange projecting toward the bathtub side is provided on the back surface of the apron, and the flange and the washing-place side end of the standing wall of the bathtub waterproof pan are interposed with packing over the entire longitudinal direction of the washing-place side end of the standing wall. The gist is to overlap and connect the overlapped portion with a metal fitting so that the packing is pressed against the flange .

本発明では、エプロンの裏面にフランジを突出状に設けて、このフランジに浴槽防水パンの立壁の洗い場側端をパッキンを介在させて重ね合わせ、重ね合わせ部分を金具で挟み込むため、エプロンを浴槽防水パンに隙間なく接続することができ、確実に止水性が確保されて、洗い場側から浴槽防水パン側への水の侵入を防ぐことができるとともに虫の侵入を確実に防ぐことができるものとなる。 In the present invention, a flange is provided on the back surface of the apron so as to protrude, and the washing wall side end of the standing wall of the bathtub waterproofing pan is overlapped with this flange with packing interposed therebetween , and the overlapped portion is sandwiched with metal fittings. it can be connected without gaps in a pan assure the water stopping is secured, and that can be reliably prevented insects from entering it is possible to prevent water from entering from the washing area side to the tub waterproof pan side .

次に、本発明を実施するための最良の形態を実施例を用いて説明する。
図１は、浴室ユニットの側面概略構成図であり、また図２は、浴室ユニットを構成する洗い場パンと浴槽防水パンの平面構成図である。
浴室ユニット１は、洗い場２ａを形成する洗い場パン２と、浴槽４を設置することのできる浴槽防水パン３と、浴槽防水パン３と洗い場パン２間に立設されるエプロン５で構成されており、浴槽防水パン３には、洗い場２ａ側を除く外周に立壁３ａ，３ｂ，３ｃが浴槽４を囲むように一体形成されている。 Next, the best mode for carrying out the present invention will be described using examples.
FIG. 1 is a schematic side view of a bathroom unit, and FIG. 2 is a plan view of a washing pan and a bathtub waterproof pan constituting the bathroom unit.
The bathroom unit 1 is composed of a washing area pan 2 that forms a washing area 2a, a bathtub waterproof pan 3 in which a bathtub 4 can be installed, and an apron 5 that stands between the bathtub waterproof pan 3 and the washing area pan 2. In the bathtub waterproof pan 3, standing walls 3 a, 3 b, 3 c are integrally formed on the outer periphery excluding the washing area 2 a side so as to surround the bathtub 4.

この浴槽防水パン３の立壁３ｂ，３ｃの洗い場パン２側の端部と、エプロン５の長手方向端縁とが接続部Ｐ，Ｐで接続されている。この接続部Ｐの構造を拡大して図３の平面拡大分解構成図で示す。
なお、図３は、浴槽防水パンの立壁３ｂとエプロン５の一方側の端縁を示しており、立壁３ｃとエプロン５の他側端縁の接続構造も同様な構造となっている。 The ends of the standing walls 3b, 3c of the bathtub waterproof pan 3 on the washing pan 2 side and the longitudinal edges of the apron 5 are connected by connecting portions P, P. The structure of the connecting portion P is enlarged and shown in a plan enlarged exploded view of FIG.
In addition, FIG. 3 has shown the edge of the standing wall 3b and the apron 5 of the bathtub waterproofing pan, and the connection structure of the standing wall 3c and the other edge of the apron 5 has the same structure.

接続部Ｐを説明すると、浴槽防水パンの立壁３ｂの洗い場２ａ側端部には、内側へ傾斜する傾斜段部３１が一体形成され、傾斜段部３１の先端で洗い場２ａ側へ突出して洗い場側端片３２が一体形成されており、この洗い場側端片３２の内側に、予め縦方向全域に亘り止水パッキン７を貼着等で取り付けておく。 The connecting part P will be explained. An inclined step portion 31 that is inclined inward is integrally formed at the end portion of the standing wall 3b of the bathtub waterproofing pan, and the inclined step portion 31 protrudes toward the washing place 2a side at the tip of the inclined step portion 31. The end piece 32 is integrally formed, and the water-stopping packing 7 is attached to the inside of the washing place side end piece 32 in advance by sticking or the like over the entire longitudinal direction.

一方、エプロン５の長手方向端縁には、浴槽４側へ突出して本体部５ａの端部裏側にフランジ５ｂが一体形成され、フランジ５ｂに対し本体部５ａ端部から洗い場２ａ側へ突出して張出片５ｃが一体形成されており、張出片５ｃの先端で外側へ折り曲げ状に突出して突出片５ｄが一体形成され、突出片５ｄの先端には、裏側が開放された断面コの字状のコの字状片５ｅが一体形成されている。 On the other hand, a flange 5b is integrally formed on the edge of the apron 5 in the longitudinal direction so as to protrude toward the bathtub 4 and on the back side of the end of the main body 5a. The flange 5b projects from the end of the main body 5a toward the washing place 2a. A protruding piece 5c is integrally formed, and a protruding piece 5d is integrally formed by protruding outward at the tip of the overhanging piece 5c. The protruding piece 5d has a U-shaped cross-section with the back side open at the tip. The U-shaped piece 5e is integrally formed.

このエプロン５のフランジ５ｂには、その内側に蝶ネジ６ａが配置され、蝶ネジ６ａからフランジ５ｂを貫通して外側へ向かってネジ部６ｂが突出されており、このネジ部６ｂの外端側に、エプロンガイド金具６を構成する移動片６ｃに形成されている雌ネジ孔が螺合されている。
移動片６ｃの浴槽防水パン３側には、外方向へ折り曲げて折曲片６ｄが一体形成され、折曲片６ｄの外端から浴槽防水パン３側へ向かって突出する挟圧片６ｅが一体形成されている。 The flange 5b of the apron 5 is provided with a thumbscrew 6a on the inner side thereof, and a screw portion 6b is projected from the thumbscrew 6a to the outside through the flange 5b. The outer end side of the screw portion 6b A female screw hole formed in the moving piece 6c constituting the apron guide fitting 6 is screwed together.
A folded piece 6d is integrally formed by bending outward on the bathtub waterproof pan 3 side of the movable piece 6c, and a pressing piece 6e protruding toward the bathtub waterproof pan 3 side from the outer end of the folded piece 6d is integrally formed. Is formed.

このような構造において、浴槽防水パンの立壁３ｂの先端の洗い場側端片３２を、止水パッキン７を介在させてエプロン５のフランジ５ｂの外側に重ね合わせ、この状態で蝶ネジ６ａを内側から締め付けてゆくと、ネジ部６ｂが回転されることにより、螺合されているエプロンガイド金具６の移動片６ｃがフランジ５ｂ側へ移動してゆき、やがては図４に示すように、エプロンガイド金具６の挟圧片６ｅが浴槽側防水パンの洗い場側端片３２の外側に当接し、さらに蝶ネジ６ａを締め付けることで、この挟圧片６ｅとエプロン５のフランジ５ｂ間に、洗い場防水パンの洗い場側端片３２と止水パッキン７を強固に挟み付けることができ、止水パッキン７はフランジ５ｂに押圧されて確実な止水性能が確保されるものである。 In such a structure, the washing side end piece 32 at the end of the standing wall 3b of the bathtub waterproof pan is overlapped on the outside of the flange 5b of the apron 5 with the water blocking packing 7 interposed therebetween, and in this state, the thumbscrew 6a is placed from the inside. When tightened, the threaded portion 6b is rotated, so that the moving piece 6c of the apron guide fitting 6 that is screwed moves to the flange 5b side. Eventually, as shown in FIG. 4, the apron guide fitting. 6 is in contact with the outside of the washing-side end piece 32 of the bathtub-side waterproof pan, and by tightening the thumbscrew 6a, the washing-proof waterproof pan of the washing-place waterproof pan is interposed between the clamping piece 6e and the flange 5b of the apron 5. The washing-end-side end piece 32 and the water stop packing 7 can be firmly sandwiched, and the water stop packing 7 is pressed against the flange 5b to ensure reliable water stop performance.

なお、接続作業は、内側より蝶ネジ６ａを手で締め付けてゆけば、エプロンガイド金具６のフランジ５ｂ側への移動に伴って、エプロン５のフランジ５ｂと浴槽防水パンの洗い場側端片３２が自然に重ね合わされてゆき、やがては挟圧片６ｅで強固に挟み付けられるものであり、接続作業は内側から蝶ネジ６ａを回すだけで良く、接続作業を簡単に行うことができるものとなる。 In addition, if the thumbscrew 6a is tightened by hand from the inside, the flange 5b of the apron 5 and the washing-end side piece 32 of the bathtub waterproofing pan are moved along with the movement of the apron guide fitting 6 toward the flange 5b. The layers are naturally overlapped and eventually are firmly clamped by the clamping pieces 6e, and the connection work can be performed simply by turning the thumbscrew 6a from the inside, and the connection work can be easily performed.

なお、止水パッキン７は上下方向に全域に設けられているため、接続部Ｐの全域に亘り止水性が確保されることとなり、洗い場２ａ側から浴槽防水パン３側に水が侵入することが確実に防がれるものとなり、また、外側から虫が侵入することも確実に防がれるものとなる。
即ち、従来においては、エプロン５の側端縁は、建て付けられた壁パネルに接続されるものであるため、壁パネルとエプロン５の側端縁間に隙間が生じていたが、本例では、エプロン５の側端縁に隙間が生ずることはなく、確実な止水性が確保されるものである。 In addition, since the water stop packing 7 is provided in the whole up-and-down direction, a water stop is ensured over the whole connection part P, and water may penetrate | invade into the bathtub waterproofing pan 3 side from the washing place 2a side. This will surely prevent the insects from entering from the outside.
That is, in the prior art, since the side edge of the apron 5 is connected to the built wall panel, there is a gap between the wall panel and the side edge of the apron 5. The gap between the side edges of the apron 5 does not occur, and a certain water-stopping property is ensured.
