The bathtub waterproofing pan 1 is configured such that a standing wall 2 is integrally formed on the outer periphery excluding the washing place pan 5 side, and the outer periphery excluding the washing place pan 5 side of the bathtub 3 is covered with the standing wall 2.
In addition, an apron 4 is attached to the washing pan 5 side where the standing wall 2 does not exist, and the washing pan 5 side of the bathtub 3 is closed by the apron 4.

この浴槽防水パン１の立壁２の上端と浴槽３との接続部Ｐの部分を図２の拡大断面図で示す。
浴槽３は、その上端側に外方へ向かって略水平に突設されたフランジ部３ａが一体形成され、このフランジ部３ａには一段高く段部３ｂが形成されており、フランジ部３ａの外側端には、さらに上方へ立ち上げて水返し片３ｃが一体形成されている。なお、浴槽３のフランジ部３ａの裏側には、段部３ｂ付近から下方へ垂設された補強リブ３ｄが一体形成されている。
また、浴槽防水パン１の立壁２は、その上端側に外側へ水平に折り曲げて折曲部２ａが一体形成され、折曲部２ａから上方へさらに立ち上げて上端立壁部２ｂが一体形成されており、上端立壁部２ｂの上端で外側へ略水平に折り曲げて突出部２ｃが一体形成されている。 The part of the connection part P of the upper end of the standing wall 2 of this bathtub waterproofing pan 1 and the bathtub 3 is shown with the expanded sectional view of FIG.
The bathtub 3 is integrally formed with a flange portion 3a projecting substantially horizontally outwardly at the upper end side thereof, and a stepped portion 3b is formed on the flange portion 3a. A water return piece 3c is integrally formed at the end by raising further upward. In addition, a reinforcing rib 3d that is suspended downward from the vicinity of the stepped portion 3b is integrally formed on the back side of the flange portion 3a of the bathtub 3.
Further, the standing wall 2 of the bathtub waterproof pan 1 is horizontally bent outward at the upper end side thereof to integrally form a bent portion 2a, and further rises upward from the bent portion 2a to integrally form the upper end standing wall portion 2b. And the protrusion 2c is integrally formed by bending substantially horizontally outward at the upper end of the upper end standing wall 2b.

浴槽３のフランジ部３ａの裏面に、補強リブ３ｄにほぼ当接させた状態で予めパッキン６を貼り付けておく。このパッキン６は、例えば発泡ウレタンあるいはゴムの発泡体で構成されたものであり、材質はどのようなものであっても良く、止水性が確保できるものであれば良い。   The packing 6 is affixed in advance to the back surface of the flange portion 3a of the bathtub 3 in a state of being substantially in contact with the reinforcing rib 3d. The packing 6 is made of, for example, foamed urethane or rubber foam, and any material may be used as long as it can ensure water-stopping.

本例では、浴槽防水パンの立壁２の上端に第１の金具７が立設されており、この第１の金具７の上端側に第２の金具８をビス９で固定して、第２の金具８と第１の金具７間に浴槽３の水返し片３ｃを挟み込んで、パッキン６を第１の金具７で浴槽３側へ押圧させ、パッキン６が逃げないようにしており、パッキン６に浴槽防水パンの立壁２の上端を外側より圧着させて止水性を確保するように構成したものである。   In this example, the first metal fitting 7 is erected on the upper end of the standing wall 2 of the bathtub waterproofing pan, and the second metal fitting 8 is fixed to the upper end side of the first metal fitting 7 with a screw 9, The water return piece 3c of the bathtub 3 is sandwiched between the metal fitting 8 and the first metal fitting 7, and the packing 6 is pressed toward the bathtub 3 side by the first metal fitting 7 so that the packing 6 does not escape. The upper end of the standing wall 2 of the bathtub waterproof pan is pressed from the outside to ensure water-stopping.

第１の金具７は、浴槽防水パンの立壁２の上端立壁部２ｂの外側にビス１１で固定される固定片７ａと、この固定片７ａの上端で外側へ折り曲げられて立壁２の突出部２ｃの下面に当接される水平片７ｂと、この水平片７ｂから上方へ向かって一体状に立ち上げられた立上片７ｃで構成されており、立上片７ｃは浴槽の水返し片３ｃよりも上方に位置するように立ち上げ形成されたものである。   The first metal fitting 7 is fixed to the outer side of the upper end standing wall 2b of the standing wall 2 of the bathtub waterproofing pan with a screw 11, and is bent outward at the upper end of the fixing piece 7a to be protruded 2c of the standing wall 2. The horizontal piece 7b is in contact with the lower surface of the tub, and the rising piece 7c is integrally raised upward from the horizontal piece 7b. The rising piece 7c is formed from the water return piece 3c of the bathtub. Is also formed so as to be positioned above.

また、第２の金具８は、浴室内側から第１の金具７の立上片７ｃにビス９で重ね合わせて固定される固定片８ａと、この固定片８ａの下端から浴室内へ傾斜した傾斜片８ｂと、傾斜片８ｂの下端から垂設されて、水返し片３ｃの内側に配置される壁パネルフレームの立上片１０ｄに当接する当接片８ｃで構成されている。
なお、浴槽のフランジ部３ａ上に壁パネル１０が載置されるが、壁パネル１０の下端裏側には略コの字状断面のフレームが設けられており、このフレームは、水平に延びる水平片１０ａと、水平片１０ａの内端から垂設された垂下片１０ｂと、垂下片１０ｂの下端で水返し片３ｃ側へ水平に延びる底片１０ｃと、底片１０ｃから上方へ立ち上げられて水返し片３ｃに当接する立上片１０ｄで構成されており、このフレームの立上片１０ｄの内側に第２の金具８の当接片８ｃが当接される。 The second metal fitting 8 includes a fixed piece 8a that is fixed to the rising piece 7c of the first metal piece 7 with a screw 9 from the inside of the bathroom, and an inclination inclined from the lower end of the fixed piece 8a into the bathroom. It consists of a piece 8b and a contact piece 8c that is suspended from the lower end of the inclined piece 8b and abuts against the rising piece 10d of the wall panel frame disposed inside the water return piece 3c.
Although the wall panel 10 is placed on the flange portion 3a of the bathtub, a frame having a substantially U-shaped cross section is provided on the back side of the lower end of the wall panel 10, and this frame is a horizontal piece extending horizontally. 10a, a hanging piece 10b suspended from the inner end of the horizontal piece 10a, a bottom piece 10c extending horizontally toward the water return piece 3c at the lower end of the hanging piece 10b, and a water return piece raised upward from the bottom piece 10c It is comprised by the standing piece 10d contact | abutted to 3c, and the contact piece 8c of the 2nd metal fitting 8 is contact | abutted inside the standing piece 10d of this flame | frame.

このような構造の接続部Ｐとしたため、浴槽防水パンの立壁２の上端側に第１の金具７を固定させて立設させることで、浴槽３に貼り付けられているパッキン６を外側から押圧して、パッキン６が外側へ逃げるのを良好に防ぐことができるものとなる。また、この第１の金具７に対しビス９で浴室内より第２の金具８を固定することで、浴槽３の水返し片３ｃは第１の金具７の立上片７ｃと第２の金具８の当接片８ｃ間に挟み込まれた状態となり、第２の金具８を介して第１の金具７は浴槽３に強固に固定されることとなる。   Since it is set as the connection part P of such a structure, the packing 6 affixed on the bathtub 3 is pressed from the outside by fixing the 1st metal fitting 7 to the upper end side of the standing wall 2 of a bathtub waterproofing pan, and standing. Thus, it is possible to satisfactorily prevent the packing 6 from escaping to the outside. Further, by fixing the second metal fitting 8 from the inside of the bathroom to the first metal fitting 7 with a screw 9, the water return piece 3c of the bathtub 3 is connected to the rising piece 7c of the first metal fitting 7 and the second metal fitting. The first metal fitting 7 is firmly fixed to the bathtub 3 through the second metal fitting 8.

この状態では、浴槽防水パンの立壁２の上端は、第１の金具７を介してパッキン６に外側から圧着された状態となる。そのため浴槽３側で発生した漏水は、パッキン６に浴槽防水パンの立壁２が圧着されているため、浴室ユニット外に漏れることはなく、また、浴槽のフランジ部３ａと浴槽防水パンの立壁２の上端と浴槽３に囲まれる空間は塞がれるため、浴室ユニットの外部から虫が浴室内に侵入することも確実に防がれるものとなる。
このように金具７，８を用いてパッキン６を一定の力で浴槽３に押し付け、浴槽防水パンの立壁２の上端をパッキン６に圧着状態で接続して、パッキン６で確実な止水性を確保することができるものである。 In this state, the upper end of the standing wall 2 of the bathtub waterproof pan is in a state of being crimped to the packing 6 from the outside via the first metal fitting 7. Therefore, the water leakage generated on the bathtub 3 side is not leaked outside the bathroom unit because the standing wall 2 of the bathtub waterproof pan is pressure-bonded to the packing 6, and the flange portion 3a of the bathtub and the standing wall 2 of the bathtub waterproof pan Since the space surrounded by the upper end and the bathtub 3 is closed, insects can be reliably prevented from entering the bathroom from the outside of the bathroom unit.
In this way, the packing 6 is pressed against the bathtub 3 with a constant force using the metal fittings 7 and 8, and the upper end of the standing wall 2 of the bathtub waterproofing pan is connected to the packing 6 in a crimped state. Is something that can be done.

なお、本例では、パッキン６には浴槽３側から水が侵入することはなく、そのためパッキン６は水に強いパッキンである必要もなく、安価な材質のパッキン６を用いることができるものである。   In this example, water does not enter the packing 6 from the bathtub 3 side. Therefore, the packing 6 does not have to be strong against water, and an inexpensive packing 6 can be used. .
