【０００２】
【従来の技術】
従来この種の床部材としては、例えば上板と下板とを重ね合わせ、この上板と下板との間に発泡樹脂を充填したものや、ＦＲＰ（ガラス繊維強化プラスチック）製の床本体と、外装層と、発泡ウレタン層とを一体状に積層したもの、或いは熱可塑性樹脂の中空成形体内に発泡材を充填してなるもの等が知られている（例えば特開平９―１９５３４４号公報、特開平１０―２１９７７６号公報、特開２００１―３２９５９０号公報等参照）。
【０００３】
【発明が解決しようとする課題】
ところでこの種の床部材は、熱エネルギーのロスを軽減できるよう断熱性に優れ、同時に、入浴者の体重を充分支えることができるよう耐荷重性や剛性が大きい状態に形成されているのが望ましい。
【０００４】
しかるに従来品は、通常、既設の浴室洗い場の床面に下面をべたに接触させるよう形成されていたから、従来品によると、内部が発泡樹脂の断熱層に形成されてはいるものの、熱が床下に奪われ易く、断熱性を充分発揮させることができない、という問題点があった。
【０００５】
又従来、この種の床部材の場合、例えば上板（表面パネル）の下面に補強リブを設けると、このリブが支障となって温水の流通管を配管することが困難になる、という問題があった。
従って従来のこの種の床部材は、上板の下面が平面状に形成されるのが通例であったから、従来品によると、強度を充分確保できず、耐荷重性や剛性に欠ける、という問題点があった。
【０００６】
本発明は、このような従来の問題点に鑑み、提案されたものである。
従って本発明の技術的課題は、発泡樹脂の断熱層を備えてなる断熱床部材において、熱が床下に奪われることを防止でき、断熱性を向上できると共に、耐荷重性や剛性を充分確保できるよう形成した断熱床部材を提供することにある。
【０００７】

【００２３】
以上の処において、本発明の場合、上記のネジ止め用の箇所５は、壁４と独立して形成される場合には限られず、例えば図４等に示されるように、壁４と一体状に形成されているのでも良い。
【００２４】
更に本発明品は、図１１〜図１３に示されるように、内部に温水の流通管１０を蛇行状に配管し、暖房機能付きに構成するのでも良い。同図において、１１は、温水の流通管１０を挟み付けて固定するための左右一対の挟持片である。この挟持片１１は、表面パネル１の下面に、例えば表面パネル１と一体成形されて複数形成されている。温水の流通管１０は、この挟持片１１によって表面パネル１に接触した状態で閉鎖スペースに蛇行状に配管されている。
【００２５】
この実施形態の本発明品を組み立てる場合は、作業者は、先ず温水の流通管１０を挟持片１１に嵌め付けて蛇行状に配管し、次に閉鎖スペースに発泡樹脂３を充填する。この場合作業者は、注入する発泡樹脂３の発泡圧に負けないよう、上下をプレスした状態で充填作業を行う。上記の温水の流通管１０は、これにより発泡樹脂３の断熱層に埋設される。そして作業者は、その後、面状材２を介して架台６をネジ７で止め付ける。
【００２６】
【発明の効果】
以上説明したように本発明は、発泡樹脂の断熱層を備えてなる断熱床部材において、表面パネルの周辺部に壁を枠状に形成し、この壁で囲まれる表面パネルの下側位置にネジ止め用の箇所を壁と同じ高さに複数形成し、このネジ止め用の箇所に面状材を介して細長状の架台をネジ止めして細長状の架台を面状材の下面に設け、上記の壁を、表面パネルと一体成形して内壁と外壁とで溝状空間部を有して矩形の枠状に形成すると共に、この溝状空間部に発泡樹脂を逃すための逃し孔を上記の内壁の矩形方向の各辺に等間隔に複数開口し、この逃し孔を介して溝状空間部に膨出している発泡樹脂に向かって面状材の周縁部を屈曲し、この周縁部を壁の溝状空間部に係合しているものである。
【００２７】
従って本発明の場合は、架台によって下面がユニットバス設置面にべたに接触することを防止できるから、これによれば断熱性が向上する。又本発明品は、架台によって補強できるから、耐荷重性や剛性が高くなり、ネジ止め用の箇所及び壁によって表面パネルと面状材とを一体化できるから、全体の強度を充分確保できる。
又本発明の場合は、閉鎖スペースに発泡樹脂を注入したとき、この閉鎖スペースから膨出する発泡樹脂を溝状空間部に入らせて体裁良く処理でき、又閉鎖スペースからはみ出たバリを除去する必要がない。
又本発明の場合は、表面パネルと面状材とを重ね合わせたとき、面状材の周縁部を体裁良く始末でき、又溝状空間部に浸入している発泡樹脂を面状材の周縁部で隠すことができ、体裁が良くなるものである。
