浴槽側防水パン1には浴槽(図示しない)が設置されている。浴槽側防水パン1は、支持脚を有する架台(図示しない)に支持されており、洗い場側防水パン2も支持脚に支持されている。
An embodiment of the present invention will be described below with reference to the drawings.
As shown in Fig. 1, on the floor slab in the building where the bathroom unit is housed or on the foundation of the bathroom unit, a bathtub side waterproof pan 1 (bathroom waterproof pan) and a washing area side waterproof pan 2 (bathroom waterproof A pan) is installed, and adjacent long sides of both are connected.
A bathtub (not shown) is installed in the bathtub-side waterproof pan 1 . The bathtub-side waterproof pan 1 is supported by a frame (not shown) having supporting legs, and the washing-place-side waterproof pan 2 is also supported by the supporting legs.

図2、図3に示すように、浴槽側防水パン1は、熱可塑性樹脂製の発泡体層10aとこの発泡体層10aの上面に積層された熱可塑性樹脂製の表皮層10bにより構成されている。本実施形態では、最初にポリスチレン(PS)、HIPS、ABS等のスチレン系樹脂シートを真空成形することにより、上述した浴槽側防水パン1の上面形状に対応した表皮層10bを得る。なお、表皮層10bの厚さは、例えば1~4mm、好ましくは1~3mm、より好ましくは1~2mmである。
その後で、発泡金型内に表皮層10bをセットし、ビーズ発泡成形により発泡ポリスチレン(EPS)製の発泡体層10aを得る。この発泡成形の過程で、発泡体層10aと表皮層10bが熱溶着されるので、両者を貼り合わせる工程を省くことができる。なお、これら発泡体層10aと表皮層10bを接着剤により貼り合わせてもよい。
洗い場側防水パン2も発泡体層を備えているが、本実施形態では浴槽側防水パン1と異なる層構造を有している。
As shown in FIGS. 2 and 3, the bathtub-side waterproof pan 1 is composed of a thermoplastic resin foam layer 10a and a thermoplastic resin skin layer 10b laminated on the upper surface of the foam layer 10a. there is In this embodiment, first, a styrene-based resin sheet such as polystyrene (PS), HIPS, ABS, or the like is vacuum-formed to obtain the skin layer 10b corresponding to the shape of the upper surface of the bathtub-side waterproof pan 1 described above. The thickness of the skin layer 10b is, for example, 1 to 4 mm, preferably 1 to 3 mm, more preferably 1 to 2 mm.
After that, the skin layer 10b is set in a foaming mold, and a foam layer 10a made of expanded polystyrene (EPS) is obtained by bead foaming. Since the foam layer 10a and the skin layer 10b are heat-sealed in the process of foam molding, the step of bonding the two can be omitted. Note that the foam layer 10a and the skin layer 10b may be bonded together with an adhesive.
The washing place side waterproof pan 2 also has a foam layer, but in this embodiment, it has a layer structure different from that of the bathtub side waterproof pan 1 .

浴槽側防水パン1は、底部11と、その周縁の長辺に形成された立ち上がり部12,13と、短辺に形成された立ち上がり部14を有している。底部11には、洗い場側防水パン2寄りに排水口11aが形成され、この排水口11aには排水ユニット(図示しない)が装着されている。 The bathtub-side waterproof pan 1 has a bottom portion 11, rising portions 12 and 13 formed on the long sides of the periphery thereof, and rising portions 14 formed on the short sides. A drain port 11a is formed in the bottom portion 11 near the waterproof pan 2 on the washing place side, and a drain unit (not shown) is attached to the drain port 11a.

A rising portion 12 corresponding to one long side of the bathtub-side waterproof pan 1 is connected to the wash-place-side waterproof pan 2. - 特許庁
Two wall panels (not shown) are installed on the rising portion 13 corresponding to the other long side of the bathtub side waterproof pan 1, and one wall panel is installed on each of the rising portions 14 on the two short sides. . Two wall panels are installed on the long side apart from the waterproof pan 1 on the bathtub side, one wall panel is installed on one short side, and a door is installed on the other short side. is installed. These wall panels and doors enclose the bathroom.

上記浴槽側防水パン1の短辺には、底部11と立ち上がり部14との間に、その中間高さの棚部15が形成されており、各棚部15には、2つの開口部16が互いに離間して形成されている。開口部16は、上記発泡体層10aと表皮層10bを垂直に貫いている。 On the short side of the bathtub-side waterproof pan 1, a shelf portion 15 with an intermediate height is formed between the bottom portion 11 and the rising portion 14, and each shelf portion 15 has two openings 16. They are formed apart from each other. The opening 16 vertically penetrates the foam layer 10a and the skin layer 10b.

開口部16は、平面長円形状をなしており、発泡体層10aの内周には、中間部から下端に至る支持領域16aを有している。この支持領域16aは、下端に向かって徐々に開口部16の中心軸線に近づくようなテーパをなしている。このテーパは、発泡体層10aの成形時の抜き勾配に相当し、そのテーパ角度は約2°である。 The opening 16 has an elliptical planar shape, and has a support region 16a extending from the middle portion to the lower end on the inner periphery of the foam layer 10a. The support area 16a is tapered to gradually approach the central axis of the opening 16 toward the lower end. This taper corresponds to the draft during molding of the foam layer 10a, and the taper angle is about 2°.

図4に示すように、開口部16の上端部周縁には、ほぼ長円形状をなす環状のビス受け部材18が配置されている。このビス受け部材18は、PS、HIPS、ABS等のスチレン系樹脂製の射出成形品からなり、開口部16より大きく、径方向外方向に突出する複数例えば4つのボス部18aを有している。 As shown in FIG. 4, an annular screw receiving member 18 having a substantially elliptical shape is arranged around the upper edge of the opening 16 . The screw receiving member 18 is made of an injection-molded product made of a styrene resin such as PS, HIPS, ABS, etc., and has a plurality of, for example, four, boss portions 18a that are larger than the opening 16 and protrude radially outward. .

ビス受け部材18は発泡体層10aに埋め込まれている。具体的に説明すると、予め成形した表皮層10bの裏面にビス受け部材18を接着させた状態で、発泡金型にセットし、上述のビーズ発泡により発泡体層10aを成形する。このインサート成形により、ビス受け部材18が発泡体層10aに埋設されるとともに表皮層10bで覆われる。ビス受け部材18も表皮層10bと同様にスチレン系樹脂製であるので、発泡成形の工程において発泡体層10aと熱溶着され、一体化される。
なお、ビス受け部材18の内周も発泡体層10aにより覆われている。
The screw receiving member 18 is embedded in the foam layer 10a. Specifically, with the screw receiving member 18 adhered to the rear surface of the skin layer 10b formed in advance, the surface layer 10b is set in a foaming mold, and the foam layer 10a is formed by foaming the beads as described above. By this insert molding, the screw receiving member 18 is embedded in the foam layer 10a and covered with the skin layer 10b. Like the skin layer 10b, the screw receiving member 18 is also made of a styrene-based resin, so that it is thermally welded and integrated with the foam layer 10a in the process of foam molding.
The inner periphery of the screw receiving member 18 is also covered with the foam layer 10a.

上記発泡金型の型面には4つの小さな突起が形成されており、これら突起に上記ビス受け部材18のボス部18aを位置させた状態で表皮層10bが発泡金型にセットされる。発泡成形時の発泡圧により、表皮層10bには、突起に対応した凹みが形成される。浴室施工現場において、この凹みをガイドにして錐により表皮層10bとビス受け部材18のボス部18aを穴あけ加工する。その結果、ビス受け部材18のボス部18aにタッピング穴18xが形成されるとともに、表皮層10bにタッピング穴18xと一致した挿通穴10xが形成される。 Four small projections are formed on the mold surface of the foaming mold, and the skin layer 10b is set in the foaming mold with the boss portions 18a of the screw receiving members 18 positioned on these projections. A depression corresponding to the projection is formed in the skin layer 10b by a foaming pressure during foam molding. At the construction site of the bathroom, the skin layer 10b and the boss portion 18a of the screw receiving member 18 are drilled with a drill using this dent as a guide. As a result, a tapping hole 18x is formed in the boss portion 18a of the screw receiving member 18, and an insertion hole 10x corresponding to the tapping hole 18x is formed in the skin layer 10b.

浴槽側防水パン1の下側の空間に配置された架橋ポリエチエン製(樹脂製)の給水管P1(配管)と給湯管P2(配管)は、4つの開口部16のうちの選択された1つ(本実施形態では右下の開口部16)を通って、浴槽側防水パン1の上方に導出され、その先端が給水・給湯栓(図示しない)に接続されている。 A water supply pipe P1 (pipe) and a hot water supply pipe P2 (pipe) made of crosslinked polyethylene (made of resin) arranged in the space below the bathtub-side waterproof pan 1 are selected from four openings 16. It is led out above the bathtub-side waterproof pan 1 through (in this embodiment, the lower right opening 16), and its tip is connected to a water/hot water tap (not shown).
