したがって、雌ねじ部材３４の中間軸部３４０４が薄肉部２００２に挿通され、先端軸部３４０６が雌ねじ部材挿通孔３８に挿通されることで、雌ねじ部材３４は室外側取り付け板３０に対して側壁１８の厚さ方向と直交する方向に移動不能に係止しかつ室外方向に移動不能に係止される。 As shown in FIG. 5 (C), female screw member insertion holes are formed coaxially with the female screw member insertion holes 36 and 38 in the surface plate 22 on both sides and the thin wall portion 2002 of the core 20, and side walls are formed by these female screw member insertion holes. A female screw member insertion hole 40 penetrating 18 is formed. The female screw member insertion hole 40 has a cross-sectional shape that corresponds to the female screw member 34.
More specifically, the female screw member insertion hole 40 is formed as a concave portion 4001 in which the head 3402 of the female screw member 34 is accommodated at the surface plate 22 and the indoor side attachment plate 30 located on the toilet room side. The recess 4001 includes the female screw member insertion hole 36 of the indoor mounting plate 30. The concave portion 4001 is formed by a locking surface 4002 formed of a conical surface that the head side locking surface 3412 locks, and the inside of the locking surface 4002 is a hole through which the intermediate shaft portion 3404 is inserted.
Therefore, the head 3402 of the female screw member 34 is accommodated in the recess 4001 so that the female screw member 34 is immovably locked with respect to the indoor mounting plate 30 in the direction orthogonal to the thickness direction of the side wall 18 and is outdoor. Locked in the direction immovable.
In addition, by providing the locking surface 4002 and the locking surface 3412 (see FIG. 8), which are conical surfaces, on both the female screw member 34 and the indoor side mounting plate 30, no protrusion is generated on the indoor side. The design of the bathroom is ensured.
As shown in FIG. 5C, the female screw member insertion hole 40 is formed by a hole through which the intermediate shaft portion 3404 is inserted in the thin portion 2002, and the female screw through which the distal end shaft portion 3406 is inserted in the outdoor mounting plate 32. A member insertion hole 38 is formed. Therefore, a locking surface 4004 made of an annular flat surface centering on a hole through which the distal end shaft portion 3406 is inserted is located on the face of the outdoor mounting plate 32 on the restroom side, and an intermediate shaft is located on the locking surface 4004. The part-side locking surface 3414 is locked.
Accordingly, the intermediate shaft portion 3404 of the female screw member 34 is inserted into the thin-walled portion 2002, and the distal end shaft portion 3406 is inserted into the female screw member insertion hole 38, so that the female screw member 34 is located on the side wall 18 with respect to the outdoor mounting plate 30. It is locked so as not to move in the direction perpendicular to the thickness direction and locked so as not to move in the outdoor direction.

次に、このような取り付け部２６を有する側壁１８の製造方法について図５を参照して説明する。
図５（Ａ）に示すように、まず、コア２０に孔２０１０を開け、例えば、接着剤２０１２などを用いて薄肉部２００２をコア２０の孔２０１０に接着する。
次に、図５（Ｂ）に示すように、薄肉部２００２が接着されることで形成されたコア２０の両面の凹部２８に、それぞれ室内側取り付け板３０と室外側取り付け板３２とを、例えば、接着剤２０１２などを用いて接着する。
次に、室内側取り付け板３０と室外側取り付け板３２とが接着されたコア２０の両面に表面板２２を、例えば、接着剤２０１２などを用いて接着し、側壁１８を得る。
そして、図５（Ｃ）に示すように、側壁１８に雌ねじ部材挿通孔４０を形成する。
最後に、雌ねじ部材挿通孔４０に雌ねじ部材３４を挿通し、接着剤により接着する。
なお、薄肉部２００２や室内側取り付け板３０、室外側取り付け板３２に予め雌ねじ部材挿通孔を形成しておくなど、製造方法は種々考えられる。 Next, a method for manufacturing the side wall 18 having such an attachment portion 26 will be described with reference to FIG.
As shown in FIG. 5A, first, a hole 2010 is formed in the core 20, and the thin portion 2002 is bonded to the hole 2010 of the core 20 using, for example, an adhesive 2012 or the like.
Next, as shown in FIG. 5B, the indoor side mounting plate 30 and the outdoor side mounting plate 32 are respectively attached to the concave portions 28 on both surfaces of the core 20 formed by bonding the thin-walled portion 2002, for example. Bonding is performed using an adhesive 2012 or the like.
Next, the surface plate 22 is bonded to both surfaces of the core 20 to which the indoor side mounting plate 30 and the outdoor side mounting plate 32 are bonded, for example, using an adhesive 2012 or the like, and the side wall 18 is obtained.
Then, as shown in FIG. 5C, the female screw member insertion hole 40 is formed in the side wall 18.
Finally, the female screw member 34 is inserted into the female screw member insertion hole 40 and bonded with an adhesive.
Various manufacturing methods are conceivable, such as forming a female screw member insertion hole in advance in the thin wall portion 2002, the indoor side mounting plate 30, and the outdoor side mounting plate 32.

次に、化粧室ユニット１０の側壁１８にアテンダントシート１２を取り付ける場合について説明する。
図１、図２に示すように、アテンダントシート１２は、例えば、溝型鋼からなるフレーム２４に、座席、背もたれなどが設けられたものである。
アテンダントシート１２は、フレーム２４に、複数箇所が取り付け部２６に取り付けられることで側壁１８に配置されている。
より詳細には、図２、図３に示すように、フレーム２４の複数箇所においてそれぞれウェブ２４０２を挿通したボルト４２の雄ねじ４２０２が、雌ねじ部材３４の雌ねじ３４０８に螺合されることで、フレーム２４と取り付け部２６とが結合される。 Next, the case where the attendant sheet 12 is attached to the side wall 18 of the restroom unit 10 will be described.
As shown in FIGS. 1 and 2, the attendant seat 12 is a frame 24 made of, for example, channel steel and provided with a seat, a backrest, and the like.
The attendant seat 12 is disposed on the side wall 18 by attaching a plurality of places to the frame 24 and the attachment portion 26.
More specifically, as shown in FIGS. 2 and 3, the male screw 4202 of the bolt 42 inserted through the web 2402 at each of a plurality of locations of the frame 24 is screwed into the female screw 3408 of the female screw member 34. And the attachment portion 26 are coupled.

次に、アテンダントシート１２に荷重がかかった場合の作用について説明する。
アテンダントシート１２に、化粧室ユニット１０から離れる方向に荷重がかかった場合、この荷重は、ボルト４２から雌ねじ部材３４に伝達される。そして、係止面３４１２が係止面４００２に係止し、また、係止面３４１４が係止面４００４に係止し、この荷重は雌ねじ部材３４から室内側取り付け板３０と室外側取り付け板３２に分散して伝達される。ここで室内側取り付け板３０と室外側取り付け板３２とは接着剤により側壁１８と一体化されているので、この分散された荷重は、さらに分散されて側壁１８に伝達される。したがって、アテンダントシート１２に、化粧室ユニット１０から離れる方向に荷重がかかった場合、応力集中が生じることなく取り付け部２６の周囲の側壁１８の箇所でこの荷重を分散して受ける。
また、アテンダントシート１２に、化粧室ユニット１０の側壁１８に対して直交する方向に荷重がかかった場合、すなわち、側壁１８の上下、左右方向に荷重がかかった場合、この荷重は、ボルト４２から雌ねじ部材３４に伝達される。そして、先端軸部３４０６が室外側取り付け板３２の雌ねじ部材挿通孔３８の内周面に係止し、この荷重は、主として、雌ねじ部材３４から室外側取り付け板３２に分散して伝達される。ここで室外側取り付け板３２は接着剤により側壁１８と一体化されているので、荷重は、分散されて側壁１８に伝達される。したがって、化粧室ユニット１０の側壁１８に対して直交する方向に荷重がかかった場合、応力集中が生じることなく先端軸部３４０６の周囲の側壁１８の箇所でこの荷重を分散して受ける。
また、アテンダントシート１２に、化粧室ユニット１０の室内方向に荷重がかかった場合、フレーム２４が側壁１８に押し当てられ、側壁１８全体で荷重を分散して受ける。 Next, the operation when a load is applied to the attendant seat 12 will be described.
When a load is applied to the attendant sheet 12 in a direction away from the bathroom unit 10, this load is transmitted from the bolt 42 to the female screw member 34. The locking surface 3412 is locked to the locking surface 4002, and the locking surface 3414 is locked to the locking surface 4004, and this load is applied from the female screw member 34 to the indoor side mounting plate 30 and the outdoor side mounting plate 32. Is distributed and transmitted. Here, since the indoor side mounting plate 30 and the outdoor side mounting plate 32 are integrated with the side wall 18 by an adhesive, the dispersed load is further dispersed and transmitted to the side wall 18. Therefore, when a load is applied to the attendant sheet 12 in a direction away from the restroom unit 10, the load is distributed and received at the side wall 18 around the attachment portion 26 without stress concentration.
In addition, when a load is applied to the attendant sheet 12 in a direction perpendicular to the side wall 18 of the restroom unit 10, that is, when a load is applied in the vertical and horizontal directions of the side wall 18, the load is applied from the bolt 42. It is transmitted to the female screw member 34. The distal end shaft portion 3406 is engaged with the inner peripheral surface of the female screw member insertion hole 38 of the outdoor attachment plate 32, and this load is mainly distributed and transmitted from the female screw member 34 to the outdoor attachment plate 32. Here, since the outdoor mounting plate 32 is integrated with the side wall 18 by an adhesive, the load is dispersed and transmitted to the side wall 18. Therefore, when a load is applied in a direction orthogonal to the side wall 18 of the restroom unit 10, this load is distributed and received at the side wall 18 around the distal end shaft portion 3406 without stress concentration.
Further, when a load is applied to the attendant sheet 12 in the room direction of the restroom unit 10, the frame 24 is pressed against the side wall 18, and the load is distributed and received by the entire side wall 18.

本実施の形態によれば、側壁１８の複数箇所にアテンダントシート１２を取り付けるための取り付け部２６が設けられ、各取り付け部２６は、それぞれ小形な室内側取り付け板３０、室外側取り付け板３２、雌ねじ部材３４で構成できるので、従来に比べ取り付け部２６の軽量化を大幅に図れ、したがって、側壁１８の大幅な軽量化、ひいては化粧室ユニット１０の軽量化を格段と図る上で有利となる。
また、アテンダントシート１２に荷重がかかった場合、応力集中の発生を抑制でき、化粧室ユニット１０の軽量化を図りつつアテンダントシート１２の取り付け強度を確保することが可能となる。 According to the present embodiment, the attachment portions 26 for attaching the attendant sheet 12 are provided at a plurality of locations on the side wall 18, and each attachment portion 26 includes a small indoor-side attachment plate 30, an outdoor-side attachment plate 32, and a female screw. Since it can be constituted by the member 34, it is possible to greatly reduce the weight of the mounting portion 26 as compared with the prior art, and therefore, it is advantageous for significantly reducing the weight of the side wall 18 and consequently the weight of the restroom unit 10.
Further, when a load is applied to the attendant sheet 12, it is possible to suppress the occurrence of stress concentration, and to secure the attachment strength of the attendant sheet 12 while reducing the weight of the bathroom unit 10.
