Description

【０００１】
【発明の属する技術分野】
この発明は、床暖房装置に関するものである。
【０００２】
【従来の技術】
従来より、新築時に施工される床暖房装置として、例えば図１１に示すように、根太５０間にグラスウール等の断熱材５１を設け、根太５０の上に１２ｍｍ厚程度の合板を捨て貼り床５２として取付け、その後、発熱体を内蔵した床暖房パネル５３を木ねじ、接着剤等で捨て貼り床５２に固定し、さらに壁５６側の段差は床暖房パネル５３と同じ厚さの段差調整板５４を取付けて、床全体を面一にした後に、木質の耐熱フローリング材５５をゴム系或いはエポキシ系の接着剤で全面直貼りを行っていた。なお、壁際の伸縮は、後で幅木５７を取付けて吸収するようにしている。
【０００３】
【発明が解決しようとする課題】
ところが、従来の床暖房装置にあっては、新築時に取付け施工されるものであり、後付けで壁から壁まで床全面を床暖房にフローリング仕上げするのは、大掛りなリフォーム工事が必要となり敬遠されていた。しかも、従来の床暖房は、フローリング材５５に床暖房時の熱膨張や、吸湿乾燥による伸縮による目隙きや突き上げが発生しないように、フローリング材５５を接着剤で全面直貼りをするのが普通であり、このような作業は相当な熟練を要するものであり、且つ相当な施工時間を必要とするので、コスト高となっていた。さらに、全面直貼りの場合には、仮りに接着剤のバラツキ等によって接着力がアンバランスになっていると、フローリング材５５の伸縮の影響が接着力の弱い部分に集中する傾向があり、そのために従来では目隙き、突き上げ、歪みなどの発生を完全に防止することができなくなり、そのうえ部分的にフローリング材５５に傷が付いた場合や、発熱体の故障などの場合には、床全面を張り替えるという大掛りな工事が必要であった。
【０００４】
本発明は、上記従来例に鑑みてなされたもので、床暖房下地材への仕上げ床材の取り付け、取り替えが容易となり、しかも仕上げ床材の取付け位置に自由度を持たせることができ、簡単に且つ短時間で施工できると共に、仕上げ床材の目隙き、突き上げ、歪みなどの発生を完全に防止できるようにした床暖房装置を提供することを課題とし、また、専門的な技術を必要とせず、素人でも床工事が可能な床暖房装置の施工方法を提供することを課題とする。
【０００５】
【課題を解決するための手段】
上記課題を解決するために、本発明は、断熱材１の表面に発熱体２と均熱シート３とを順次積層して床暖房下地材４が構成され、この床暖房下地材４の表面に仕上げ床材５が積層された床暖房装置において、床暖房下地材４の均熱シート３の表面に、仕上げ床材５の裏面と対面する領域の略全面に亘って下側の面係合部材６を取着すると共に、仕上げ床材５の水平方向の動きを止めるための面状補強部材８を該表面と略平行な方向に配設し、この面状補強部材８の上面から該下側の面係合部材６を突出し、仕上げ床材５の裏面の周辺領域に該下側の面係合部材６に係合する上側の面係合部材７を取着し、上下の面係合部材６，７を互いに係合させることにより、床暖房下地材４の表面に仕上げ床材５が固定されて成ることを特徴としており、このように構成することで、床暖房下地材４への仕上げ床材５の取り付け、取り替えが容易となり、施工を簡単に且つ短時間で行うことができる。また、下側の面係合部材６は床暖房下地材４の表面略全体に取着されているので、仕上げ床材５を床暖房下地材４のどの位置にも自由に取付けることができ、仕上げ床材５の取付け位置に自由度を持たせることができ、一方、上側の面係合部材７は仕上げ床材５の裏面の周辺領域に取着されているので、下側の面係合部材６との係合力に偏りが発生することがなくなり、仕上げ床材５の目隙き、突き上げ、歪みなどの発生をより完全に防止できると同時に、仕上げ床材５を剥がし易くすることができ、リフォーム工事も簡単に行うことができる。しかも、床暖房下地材４の表面に面状補強部材８を設けたから、床暖房下地材４の下面がフェルトのような弾性材であっても、仕上げ床材５の水平方向の動きを止めることができるようになり、そのうえ面状補強部材８によって断熱材１の厚みを確保して防音性能を高めることができるようになり、施工後の床の歩行感を向上させることができる。
【０００７】
上記仕上げ床材５を平面視で四角形状とし、仕上げ床材５の裏面に仕上げ床材５の一辺に沿って複数の凹溝９を互いに平行に形成するのが好ましく、この場合、凹溝９によって仕上げ床材５の伸縮の吸収を確実に行えるようになる。
上記床暖房下地材４に取着される下側の面係合部材６をループ状に形成し、仕上げ床材５に取着される上側の面係合部材７をフック状に形成するのが好ましく、この場合、軟らかいループ状の面係合部材６を床暖房下地材４の表面に大きな面積で取付けることによって、施工時に床暖房下地材４上を歩くときの歩行感がよくなる。
【０００８】
また本発明は、断熱材１の表面に発熱体２と均熱シート３とを順次積層して床暖房下地材４を構成し、この床暖房下地材４の表面に仕上げ床材５を積層するようにした床暖房装置の施工方法において、床暖房下地材４の均熱シート３の表面に、仕上げ床材５の裏面と対面する領域の略全面に亘って下側の面係合部材６を取着すると共に、仕上げ床材５の水平方向の動きを止めるための面状補強部材８を該表面と略平行な方向に配設し、この面状補強部材８の上面から該下側の面係合部材６を突出し、仕上げ床材５の裏面の周辺領域に該下側の面係合部材６に係合する上側の面係合部材７を取着し、上下の面係合部材６，７間に施工シート１０を介在させた状態で仕上げ床材５上に仕上げ床材５を載置して仕上げ床材５を位置調整した後に、施工シート１０を抜き取って上下の面係合部材６，７を互いに係合させることにより、床暖房下地材４の表面に仕上げ床材５を固定するようにしたことを特徴としている。従って、面係合部材６，７を係合させる前に施工シート１０を床暖房下地材４と仕上げ床材５との間に挟むことにより、仕上げ床材５を施工シート１０上を滑らせながら位置調整して接合精度を高めることができるので、専門的な技術を必要とせず、素人でも床工事が可能となる。しかも、床暖房下地材４の表面に面状補強部材８を設けたから、床暖房下地材４の下面がフェルトのような弾性材であっても、仕上げ床材５の水平方向の動きを止めることができるようになり、そのうえ面状補強部材８によって断熱材１の厚みを確保して防音性能を高めることができるようになり、施工後の床の歩行感を向上させることができる。
【０００９】
【発明の実施の形態】
以下、本発明の実施形態の一例を説明する。
本実施形態の床暖房装置Ａは、図２に示すように、フェルト等の断熱材１の表面に、電熱ヒータ線からなる発熱体２と、均熱シート３と、多数のループ状の面係合部材６を備えた面ファスナー１１とが順次積層されて接着された床暖房下地材４と、裏面にフック状の面係合部材７を備えた面ファスナー１２が取着された仕上げ床材５とで構成されている。尚、発熱体２は電熱ヒータ線に限られず、例えば温水チューブを均熱シート３の下面側に配設するようにしてもよいものである。
【００１０】
ここで、床暖房下地材４の均熱シート３の表面に取着される下側の面係合部材６は、仕上げ床材５の裏面と対面する領域の略全面に亘って配置されている。面係合部材６は多数の軟らかいループ状に形成されている。また、床暖房下地材４の表面には、ガラスクロス等のような薄くて強靱な面状補強部材８（シート層）が積層されている。この面状補強部材８は床暖房下地材４の表面と略平行な方向（水平方向）にシート状に形成されており、面状補強部材８の上面から上記各ループ状の面係合部材６がそれぞれ突出している。面状補強部材８は、仕上げ床材５の水平方向（図１の左右方向）の動きを止める働きをする。尚、面状補強部材８は、後述するスペーサマット１３の表面にも同様に取着されている。図２中の１０は施工シートである。この施工シート１０は、上下の面係合部材６，７の係合前に面係合部材６，７間に介在され、後述の木質フローリング材５ａの位置調整後に抜き取られるものであって、木質フローリング材５ａよりも一回り大きいサイズに形成されており、木質フローリング材５ａとの接合精度を高める働きをする。
【００１１】
一方、仕上げ床材５は、図１に示すように、平面視で長方形状に形成された複数の耐熱性の木質フローリング材５ａから成る。各木質フローリング材５ａの裏面の周辺領域には、図３（ｃ）に示すように、帯状の面ファスナー１２が略ロ字状に取着されている。この面ファスナー１２には、フック状の硬い突起から成る面係合部材７（図２）が多数突設されている。
【００１２】
また、木質フローリング材５ａの裏面にはその一辺に沿って複数の凹溝９が形成されている。図３（ｃ）に示す実施形態では、凹溝９は木質フローリング材５ａの長辺側の一辺と直交する方向Ｆに沿って互いに平行に形成されている。これら凹溝９は木質フローリング材５ａの膨張、伸縮、ねじれなどの変形を防止する働きをする。
【００１３】
また、各木質フローリング材５ａの四辺には、凹凸の接合実部１６が形成されている。この接合実部１６は、図４に示すように、木質フローリング材５ａの膨張、伸縮に対して遊びを作り、過剰な伸縮を吸収できるような形状としてある。つまり、木質フローリング材５ａの接合時に、雌実１５の下側凸部１５ａが雄実１４の下面１４ａに当たることによって、遊びｄを持った状態で接合されており、これにより、施工後において過剰に伸長した場合には、雄実１４の下面１４ａが雌実１５の下側凸部１５ａを下方向に押し下げるようにして木質フローリング材５ａ同士が接近することで、突き上げ等が生じないものであり、また、過剰に収縮した場合には、雄実１４と雌実１５との左右の重なりＬで縮みを吸収して、既存の床１７が見えるのを防止できるようになっている。なお、収縮時に目隙きが目立たないようにするために、雄実１４の上面１４ｂには木質フローリング材５ａの表面色と同じか類似した色に着色されているのが望ましい。
【００１４】
次に、床暖房装置を施工するにあたっては、先ず、フェルト等の断熱材１上に、電熱ヒータ線、均熱シート３、ループ状の面係合部材６を順次積層して接着してシート層状の床暖房下地材４を作製する。その後、図５に示すように、ロール状に巻いた床暖房下地材４を既存の床１７の上に広げて敷きつめていく。このとき両面テープ８０で床暖房下地材４の下面を既存の床１７に接着する。また、床暖房下地材４のない床部分には、電熱ヒータ線、均熱シートのないスペーサマット１３を敷設する。このスペーサマット１３は床暖房下地材４と同じ厚みに形成されており、床暖房下地材４のない部分にスペーサマット１３を敷きつめて施工することにより、壁際までの施工を面一に行うことができるようになっている。このスペーサマット１３の表面には、床暖房下地材４の表面と同様、全面に亘ってループ状の面係合部材６（図２）を備えた面ファスナーが取着されている。
【００１５】
その後、床暖房下地材４及びスペーサマット１３の上に、図６に示すように、多数枚の木質フローリング材５ａを順に敷き詰めていく。このとき、図７（ａ）のように１枚の木質フローリング材５ａより一回り大きい薄い施工シート１０を床暖房下地材４上に載置し、裏面に上側の面係合部材７が取着されている木質フローリング材５ａを施工シート１０上に載置し、図７（ａ）の矢印Ａ，Ｂで示す方向に木質フローリング材５ａを滑らせて、接合実部１６による接合が正確に行われるように木質フローリング材５ａの位置調整を行う。その後、図２、図７の矢印Ｃで示す方向に施工シート１０を引張って抜き取る。これにより、はじめて上下の面係合部材６，７が互いに係合でき、床暖房下地材４上に木質フローリング材５ａを簡単に固定することができる。このような方法で多数の木質フローリング材５ａを千鳥状となるように長さ方向にずらした状態で順に施工していく。木質フローリング材５ａを千鳥状に配置することで、伸縮による微小な寸法変化を各木質フローリング材５ａで均等に吸収して、目隙きや突き上げが目立たないようにすることができると共に、伸縮性等の変形を防止できるようになる。
【００１６】
上記のように、仕上げ床材５を、従来の接着剤の全面直貼りではなく、着脱自在な面係合部材６，７を用いて床暖房下地材４上に固定することによって、床暖房下地材４に対する仕上げ床材５の取り付け、取り替えが容易となり、簡単な施工で木質フローリング仕上げが可能となり、また、施工を短時間で行うことができるようになり、従って、新築時に床暖房装置を簡単に施工できるだけでなく、後付けで壁から壁まで床全面をフローリング仕上げする場合においても簡単に施工できる。
【００１７】
しかも、仕上げ床材５を構成する多数の木質フローリング材５ａを凹凸の接合実部１６で接合することによって、木質フローリング材５ａの伸縮を凹凸の接合実部１６で分散して吸収できるようになる。つまり、従来の接着剤による固着方法にあっては、接着のバラツキによって接着力の弱い部分に仕上げ床材の伸縮が集中したり、或いは床暖房による熱膨張や、吸湿乾燥による仕上げ床材の目隙きや突き上げ現象が発生することがあったが、本発明では、接着剤なしで木質フローリング材５ａを施工できると同時に、図４のように木質フローリング材５ａの伸縮を凹凸の接合実部１６で分散して吸収できるようにしてあるので、木質フローリング材５ａの目隙きや突き上げ現象の発生を確実に防止できるようになる。つまり、接合実部１６に目地ボンド等の接着剤を入れたりしないので、接合実部１６は施工後もある程度の自由度を有することとなり、木質フローリング材５ａの寸法伸縮を各接合実部１６で分散吸収できるようになる。
【００１８】
さらに、仕上げ床材５を平面視で四角形状とし、仕上げ床材５を構成する各木質フローリング材５ａの裏面に木質フローリング材５ａの一辺に沿って複数の凹溝９を互いに平行に形成してあるので、各凹溝９によって木質フローリング材５ａの伸縮の吸収を確実に行うことができ、目隙き、突き上げ、ねじれなどの変形防止を図ることができ、特に木質フローリング材５ａが長方形に形成されている場合には、凹溝９を長辺方向と直交する方向に凹溝９を形成することによって、伸縮等の変形防止に一層効果的となる。さらに、図３（ｄ）のようにフック状の面係合部材７を設けた帯状の面ファスナー１２を複数の凹溝９の上を横切るように取着してあるので、面ファスナー１２により木質フローリング材５ａの上下の変形を防止できるようになり、フローリングの取り扱い強度を十分に維持できるようになる。
【００１９】
また、木質フローリング材５ａの施工時において、ループ状の面係合部材６が床暖房下地材４の表面略全体に取着されているので、木質フローリング材５ａを床暖房下地材４のどの位置にも自由に取付けることができ、木質フローリング材５ａの取付け位置に自由度を持たせることができる。その一方で、フック状の面係合部材７は木質フローリング材５ａの裏面の周辺領域に取着されているので、上側の面係合部材７がバランス良く配置され、下側の面係合部材６との係合力に偏りが発生することがなくなり、木質フローリング材５ａの目隙き、突き上げ、歪みなどの発生をより完全に防止できると同時に、木質フローリング材５ａの中央部分は床暖房下地材４に固定されていないので、木質フローリング材５ａを剥がし易くすることができる。また釘などを使わないので、床暖房下地材４を傷付けたりする心配もなくなる。仮りに、床暖房装置が故障したり、仕上げ床材５に傷付いたりした場合でも、床暖房装置の取り替え、仕上げ床材５の取り替えを簡単に行うことができ、リフォーム時の作業性を大幅に向上させることができる。さらに面係合部材６，７を備えた面ファスナー１１，１２は再利用が可能であるので、一層の低コスト化を図ることができる。
【００２０】
しかも、床暖房下地材４に取着される下側の面係合部材６をループ状に形成したから、軟らかいループ状の面係合部材６を床暖房下地材４の表面に大きな面積で取付けることによって、施工時に床暖房下地材４上を歩くときの歩行感がよく、しかもループ状の面係合部材６はフック状の面係合部材７と比較して潰れ難いので、安心して作業ができるようになる。しかも、床暖房下地材４の表面にガラスクロス等の薄くて強靱な面状補強部材８を設けたから、床暖房下地材４の下面がフェルトのような弾性材であっても、木質フローリング材５ａの水平方向の動きを止めることができるようになり、そのうえ面状補強部材８によって断熱材１の厚みを確保して防音性能を高めることができるようになり、断熱材１をフェルトで形成したこととあいまって、防音効果が高まり、施工後の床の歩行感を向上させることができる。
【００２１】
また、木質フローリング材５ａの位置調整時において、薄い施工シート１０を床暖房下地材４と木質フローリング材５ａとの間に挟むことにより、木質フローリング材５ａを施工シート１０上を滑らせながら位置調整して、接合精度を高めることができるので、専門的な技術を必要とせず、素人でも床工事が可能となり、施工時間を短縮化でき、低コスト化を実現できる。さらに、床暖房下地材４が敷かれない場所に、床暖房下地材４と同じ厚みのスペーサマット１３を敷設することによって、壁際までの施工を面一に行うことができ、仕上げ床材５を壁から壁まで床全体に敷き詰めることができるようになり、敷き詰め型の床暖房の施工を簡単に行うことができるものである。また、床暖房下地材４のない部分にスペーサマット１３を敷きつめることで床全面を木質フローリング材５ａで連設することができるようになり、この場合、床の強度は床暖房下地材４ではなく、既存の床１７全体で維持されることとなり、従って、床暖房下地材４は既存の床１７に両面テープ８０で仮固定する程度でよく、既存の床１７を傷つけることもなくなる。またスペーサマット１３には、電熱ヒータ線や均熱シート３が設けられていないので、現場サイズに合わせて容易にカットでき、部屋の大きさの制約もなく、仕上がりも良好なものとなる。
【００２２】
さらに、床暖房下地材４には均熱シート３層が形成されているので、万一、水をこぼした場合でも、既存の床１７まで水が達する恐れがなく、防水性を高めることができる。なお、スペーサマット１３に均熱シート３を入れるようにすれば、床全体の防水性を容易に高めることができるようになる。また、断熱材１はフェルトで形成されているので、木質フローリング材５ａの伸縮を断熱材１によっても吸収でき、伸縮の吸収を維持した状態に保つことができるようになる。また、ループ状の面係合部材６を床暖房下地材４の表面に一体に取付けたことによって、床暖房下地材４を巻いた状態で面係合部材を梱包することができるという利点もある。
【００２３】
一方、壁際の始末は、木質フローリング材５ａと既存の壁５６側の幅木５７と間に５〜１０ｍｍ程度の隙間が形成されるように、木質フローリング材５ａ等の寸法をカットし、その後、図８（ａ）又は図８（ｂ）に示す見切り縁２０を取付ける。見切り縁２０は、木質フローリング材５ａの上から貼り付けられている。図８（ａ）は見切り縁２０がＰＶＣの押し出し品からなり、その端部に伸縮自在な略半円状の膨出部２１′を取付けた場合を示しており、図８（ｂ）は見切り縁２０に弾性を有するつば部２１を一体形成した場合を示している。いずれの場合も、伸縮可能なつば部２１，２１′によって、床暖房による加熱膨張や、湿乾による壁際での突き上げ現象の発生を防止できるようになり、既存の壁５６、或いは幅木５７との取り合いを精度良く加工する必要がないようにすることができる。また見切り縁２０を壁際に別部品として設けることによって、壁際の寸法に合わせて仕上げ床材５の寸法を正確にカットする必要がなくなる。
【００２４】
図１０は床暖房下地材４の電源供給部２５を示している。この電源供給部２５は、本体部３０と、接続部３１の間に折り曲げ可能な幅狭部３２が設けられており、幅狭部３２に連設されている接続部ケース３３を壁際に立てかけて設置することにより、床暖房下地材４への電源供給部２５の外観を幅木のような形状に仕上げることができるものである。図中の２は発熱体（電熱ヒータ線）、２ａは折り曲げ部である。このように壁際に設けられる幅木の形状とし、ヒータ線を壁際で立ち上がるようにすることで、接続部３１を本体部３０に設ける必要がなくなり、本体部３０を薄くすることが可能となる。従って、防音性や断熱性能を維持しながら、所謂バリアフリー住宅の基準である、床段差１５ｍｍ以内の薄さを実現できるようになり、床につまずいたり、ドアの開閉に支障ができることも少なくなる。また、電源供給部２５を壁際に設けたことによって、木質フローリング材５ａを剥がさなくても、床暖房下地材４の電気性能の点検が可能となる。さらに、図９に示すように、接続ケース３３に隣接して配線ダクト２２を設けるようにすれば、デザイン的にもすっきりさせることができる。図９中の２２は配線ダクト、２３は電源コード、２４はコントローラーである。
【００２５】
【実施例】
先ず、ポリエステル繊維よりなる断熱フェルト（目付５００ｇ／ｍ²、厚み５ｍｍ）の上面に、７．５ｍｍＷ／ｍの発熱能力のヒータ線をピッチ３０ｍｍ毎に、アルミシート（厚み３０μｍ）の均熱シートに配線し、さらに、ピッチ５ｍｍ×５ｍｍ（目付５００ｇ／ｍ²）のガラスネットと、ポリエステルをループ状にトリコット網みした面ファスナー（目付５０ｇ／ｍ²）とを順次積層して、各層間にホットメルトフィルムを挟んで、ホットプレスにより一体化して、２畳サイズの床暖房下地材を得る。
【００２６】
一方、壁際の段差を吸収するためのスペーサマットは、アルミ箔とヒータ線のない前述の材料（フェルト等）で作製する。
木質フローリング材は、厚み９ｍｍ×１０ｃｍ×９０ｃｍを１単位とし、表面には突き板を貼り、裏面には幅１ｍｍ×深さ５ｍｍの凹溝を１２ｍｍ毎に形成する。この木質フローリング材の裏面に、ポリエステルシート（厚み１ｍｍ）にフック状の突起を１０ｍｍ角で２０本設けた幅２０ｍｍの帯状の面ファスナーを、１０ｃｍ幅の木質フローリング材の両サイドに、接着剤で９０ｃｍの長さで貼着し、さらにタッカーで補強する。
【００２７】
木質フローリング材は、縦横とも接合用の実加工が施してあるが、伸縮の大きい長手方向の接合部（短辺）は、特に図４に示すような形状にして、より伸縮を吸収しやすくする。
そして、複数の木質フローリング材を長さ方向に４５ｃｍずらして交互に千鳥状にして、床暖房下地材上に敷設する。このとき、シリコン含浸を施した厚み１５０μｍの施工シート（紙）を床暖房下地材上に敷いて、ループ状の面係合部材が設けられた面ファスナーを覆い、その上で木質フローリング材を滑らせて、木質フローリング材の実部を接合調整をしながら位置調整して、施工シートを抜取り、上部から木質フローリング材を加圧して面係合部材を互いに係合させる。
【００２８】
【発明の効果】
以上説明したように、本発明のうち請求項１記載の発明は、断熱材の表面に発熱体と均熱シートとを順次積層して床暖房下地材が構成され、この床暖房下地材の表面に仕上げ床材が積層された床暖房装置において、床暖房下地材における均熱シートの表面に、仕上げ床材の裏面と対面する領域の略全面に亘って下側の面係合部材を取着すると共に、仕上げ床材の水平方向の動きを止めるための面状補強部材を該表面と略平行な方向に配設し、この面状補強部材の上面から該下側の面係合部材を突出し、仕上げ床材の裏面の周辺領域に該下側の面係合部材に係合する上側の面係合部材を取着し、上下の面係合部材を互いに係合させることにより、床暖房下地材の表面に仕上げ床材が固定されて成るから、従来の接着剤の全面直貼りではなく、着脱自在な面係合部材を用いることによって、床暖房下地材への仕上げ床材の取り付け、取り替えが容易となり、簡単に且つ短時間で施工することができる。従って、新築時に床暖房装置を簡単に施工できるだけでなく、後付けで壁から壁まで床全面をフローリング仕上げする場合においても簡単に施工できる。しかも下側の面係合部材は床暖房下地材の表面略全体に取着されているので、仕上げ床材を床暖房下地材のどの位置にも自由に取付けることができ、仕上げ床材の取付け位置に自由度を持たせることができる。一方、上側の面係合部材は仕上げ床材の裏面の周辺領域に取着されているので、下側の面係合部材との係合力に偏りが発生することがなくなり、仕上げ床材の目隙き、突き上げ、歪みなどの発生をより完全に防止できると同時に、仕上げ床材の中央部分は床暖房下地材に固定されていないので、仕上げ床材を剥がし易くすることができる。また釘などを使わないので、床暖房下地材を傷付けたりする心配もなくなる。また仮りに、床暖房装置が故障したり、仕上げ床材に傷付いたりした場合でも、床暖房装置の取り替え、仕上げ床材の取り替えを簡単に行うことができ、リフォーム時の作業性を大幅に向上させることができる。さらに面係合部材は再利用ができるので、一層の低コスト化を図ることができるものである。また、床暖房下地材の表面側を面状補強部材で補強することができ、仮りに床暖房下地材の下面側がフェルトのような断熱材であっても、仕上げ床材の水平方向の動きを止めることができ、歩行時などに仕上げ床材が横方向に動く恐れをなくすことができ、床の歩行感を向上させることができる。
【００３０】
また請求項２記載の発明は、請求項１において、仕上げ床材を平面視で四角形状とし、仕上げ床材の裏面に仕上げ床材の一辺に沿って複数の凹溝を互いに平行に形成したから、請求項１記載の効果に加えて、凹溝によって仕上げ床材の伸縮の吸収を確実に行うことができ、目隙き、突き上げ、ねじれなどの変形防止を図ることができる。
【００３１】
また請求項３記載の発明は、請求項１において、床暖房下地材に取着される下側の面係合部材をループ状に形成し、仕上げ床材に取着される上側の面係合部材をフック状に形成したから、請求項１記載の効果に加えて、軟らかいループ状の面係合部材を床暖房下地材の表面に大きな面積で取付けることによって、施工時に床暖房下地材上を歩くときの歩行感がよく、しかもループ状の面係合部材はフック状の面係合部材と比較して潰れ難いので、安心して作業ができる。
【００３２】
さらに、請求項４記載の発明は、断熱材の表面に発熱体と均熱シートとを順次積層して床暖房下地材を構成し、この床暖房下地材の表面に仕上げ床材を積層するようにした床暖房装置の施工方法において、床暖房下地材の表面に、仕上げ床材の裏面と対面する領域の略全面に亘って下側の面係合部材を取着すると共に、仕上げ床材の水平方向の動きを止めるための面状補強部材を該表面と略平行な方向に配設し、この面状補強部材の上面から該下側の面係合部材を突出し、仕上げ床材の裏面の周辺領域に該下側の面係合部材に係合する上側の面係合部材を取着し、上下の面係合部材間に施工シートを介在させた状態で仕上げ床材上に仕上げ床材を載置して仕上げ床材を位置調整した後に、施工シートを抜き取って上下の面係合部材を互いに係合させることにより、床暖房下地材の表面に仕上げ床材を固定するようにしたから、上下の面係合部材を係合させる前に施工シートを床暖房下地材と仕上げ床材との間に挟むことにより、仕上げ床材を施工シート上を滑らせながら位置調整して接合精度を高めることができるので、専門的な技術を必要とせず、熟練者でなくても床工事が可能となり、施工時間の短縮化及び低コスト化を実現できる。また、床暖房下地材の表面側を面状補強部材で補強することができ、仮りに床暖房下地材の下面側がフェルトのような断熱材であっても、仕上げ床材の水平方向の動きを止めることができ、歩行時などに仕上げ床材が横方向に動く恐れをなくすことができ、床の歩行感を向上させることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a floor heating device.
[0002]
[Prior art]
Conventionally, as a floor heating device to be constructed at the time of new construction, for example, as shown in FIG. 11, a heat insulating material 51 such as glass wool is provided between the joists 50, and a plywood having a thickness of about 12 mm is disposed on the joists 50 as an affixed floor 52. After installation, the floor heating panel 53 with a built-in heating element is discarded and fixed to the floor 52 with wood screws, adhesive, etc., and a step adjustment plate 54 having the same thickness as the floor heating panel 53 is attached to the step on the wall 56 side. Then, after making the entire floor flush with each other, the wooden heat-resistant flooring material 55 was directly attached to the entire surface with a rubber-based or epoxy-based adhesive. The expansion and contraction near the wall is absorbed by attaching a skirting board 57 later.
[0003]
[Problems to be solved by the invention]
However, conventional floor heating systems are installed and installed at the time of new construction, and flooring the entire floor from the wall to the wall after retrofitting requires a large-scale renovation work and is avoided. It was. In addition, in the conventional floor heating, the flooring material 55 is directly adhered to the flooring material 55 with an adhesive so that the flooring material 55 does not undergo thermal expansion during floor heating or gaps or push-ups due to expansion and contraction due to moisture absorption drying. It is normal, and such work requires considerable skill and requires considerable construction time, and thus is expensive. Furthermore, in the case of direct attachment to the entire surface, if the adhesive force is unbalanced due to variations in the adhesive or the like, the influence of expansion and contraction of the flooring material 55 tends to concentrate on the weak adhesive force part. In addition, in the past, it was impossible to completely prevent the occurrence of gaps, push-ups, distortions, etc., and in addition, when the flooring material 55 was partially damaged or the heating element failed, A large-scale construction was needed to replace the
[0004]
The present invention has been made in view of the above-described conventional example, and it is easy to attach and replace the finished floor material to the floor heating base material, and also allows the installation position of the finished floor material to have a degree of freedom. It is a challenge to provide a floor heating system that can be installed quickly and in a short time, and can completely prevent the occurrence of gaps, push-ups, distortions, etc. in the finished flooring, and requires specialized technology. However, it is an object to provide a method for constructing a floor heating apparatus that can be used even by an amateur.
[0005]
[Means for Solving the Problems]
  In order to solve the above-mentioned problem, the present invention is configured such that a floor heating base material 4 is configured by sequentially laminating a heating element 2 and a soaking sheet 3 on the surface of a heat insulating material 1. In the floor heating apparatus in which the finished floor material 5 is laminated, the lower surface engaging member is disposed on the surface of the soaking sheet 3 of the floor heating base material 4 over substantially the entire area facing the back surface of the finished floor material 5. 6 is attached,A planar reinforcing member 8 for stopping the horizontal movement of the finished floor material 5 is arranged in a direction substantially parallel to the surface, and the lower surface engaging member 6 is arranged from the upper surface of the planar reinforcing member 8. Protruding,The upper surface engaging member 7 that engages with the lower surface engaging member 6 is attached to the peripheral region of the back surface of the finished floor material 5 and the upper and lower surface engaging members 6 and 7 are engaged with each other. Thus, the finishing floor material 5 is fixed to the surface of the floor heating base material 4. With this configuration, it is easy to attach and replace the finishing floor material 5 to the floor heating base material 4. Thus, the construction can be performed easily and in a short time. Moreover, since the lower surface engaging member 6 is attached to substantially the entire surface of the floor heating base material 4, the finished floor material 5 can be freely attached to any position of the floor heating base material 4, The mounting position of the finished floor material 5 can be given a degree of freedom. On the other hand, the upper surface engaging member 7 is attached to the peripheral area on the back surface of the finished floor material 5, so that the lower surface engaging member is engaged. There is no occurrence of bias in the engaging force with the member 6, and it is possible to more completely prevent occurrence of gaps, push-ups, distortions and the like of the finished floor material 5, and at the same time, the finished floor material 5 can be easily removed. Renovation work can be done easily.In addition, since the planar reinforcing member 8 is provided on the surface of the floor heating base material 4, even if the lower surface of the floor heating base material 4 is an elastic material such as felt, the horizontal movement of the finished floor material 5 is stopped. In addition, the thickness of the heat insulating material 1 can be secured by the planar reinforcing member 8 and the soundproofing performance can be improved, and the feeling of walking on the floor after construction can be improved.
[0007]
It is preferable that the finished floor material 5 has a quadrangular shape in plan view, and a plurality of concave grooves 9 are formed in parallel to each other along one side of the finished floor material 5 on the back surface of the finished floor material 5. Thus, the expansion and contraction of the finished floor material 5 can be reliably absorbed.
The lower surface engaging member 6 attached to the floor heating base material 4 is formed in a loop shape, and the upper surface engaging member 7 attached to the finished floor material 5 is formed in a hook shape. Preferably, in this case, by attaching the soft loop-shaped surface engaging member 6 to the surface of the floor heating base material 4 in a large area, the feeling of walking when walking on the floor heating base material 4 during construction is improved.
[0008]
  In the present invention, the heating element 2 and the soaking sheet 3 are sequentially laminated on the surface of the heat insulating material 1 to form the floor heating base material 4, and the finished floor material 5 is laminated on the surface of the floor heating base material 4. In the floor heating apparatus construction method described above, the lower surface engaging member 6 is provided on the surface of the soaking sheet 3 of the floor heating base material 4 over substantially the entire area facing the back surface of the finished floor material 5. Attach andA planar reinforcing member 8 for stopping the horizontal movement of the finished floor material 5 is arranged in a direction substantially parallel to the surface, and the lower surface engaging member 6 is arranged from the upper surface of the planar reinforcing member 8. Protruding,An upper surface engaging member 7 that engages with the lower surface engaging member 6 is attached to the peripheral region of the back surface of the finished floor material 5, and the construction sheet 10 is placed between the upper and lower surface engaging members 6, 7. After placing the finished floor material 5 on the finished floor material 5 and adjusting the position of the finished floor material 5 in the interposed state, the construction sheet 10 is extracted and the upper and lower surface engaging members 6 and 7 are engaged with each other. Thus, the finishing floor material 5 is fixed to the surface of the floor heating base material 4. Accordingly, the construction sheet 10 is sandwiched between the floor heating base material 4 and the finishing floor material 5 before the surface engaging members 6 and 7 are engaged, so that the finishing floor material 5 is slid on the construction sheet 10. Since the position can be adjusted to increase the joining accuracy, no specialized skills are required, and even an amateur can perform flooring work.In addition, since the planar reinforcing member 8 is provided on the surface of the floor heating base material 4, even if the lower surface of the floor heating base material 4 is an elastic material such as felt, the horizontal movement of the finished floor material 5 is stopped. In addition, the thickness of the heat insulating material 1 can be secured by the planar reinforcing member 8 and the soundproofing performance can be improved, and the feeling of walking on the floor after construction can be improved.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an example of an embodiment of the present invention will be described.
As shown in FIG. 2, the floor heating apparatus A of the present embodiment has a heating element 2 made of an electric heater wire, a soaking sheet 3, and a large number of loop-shaped surfaces on a surface of a heat insulating material 1 such as felt. Finished flooring 5 in which a floor heating base material 4 in which surface fasteners 11 having a joining member 6 are sequentially laminated and bonded, and surface fasteners 12 having hook-like surface engaging members 7 on the back are attached. It consists of and. The heating element 2 is not limited to the electric heater wire. For example, a hot water tube may be disposed on the lower surface side of the soaking sheet 3.
[0010]
Here, the lower surface engaging member 6 attached to the surface of the soaking sheet 3 of the floor heating base material 4 is disposed over substantially the entire area facing the back surface of the finished floor material 5. . The surface engaging member 6 is formed in a number of soft loops. In addition, a thin and strong planar reinforcing member 8 (sheet layer) such as a glass cloth is laminated on the surface of the floor heating base material 4. The planar reinforcing member 8 is formed in a sheet shape in a direction (horizontal direction) substantially parallel to the surface of the floor heating base material 4, and each loop-shaped surface engaging member 6 from the upper surface of the planar reinforcing member 8. Each protrudes. The planar reinforcing member 8 serves to stop the movement of the finished flooring 5 in the horizontal direction (left-right direction in FIG. 1). The planar reinforcing member 8 is also attached to the surface of a spacer mat 13 described later. 2 in FIG. 2 is a construction sheet. This construction sheet 10 is interposed between the surface engaging members 6 and 7 before the upper and lower surface engaging members 6 and 7 are engaged, and is extracted after the position adjustment of the wood flooring material 5a described later. It is formed in a size that is slightly larger than the flooring material 5a, and functions to increase the joining accuracy with the wood flooring material 5a.
[0011]
On the other hand, as shown in FIG. 1, the finished floor material 5 is composed of a plurality of heat-resistant wood flooring materials 5 a formed in a rectangular shape in plan view. As shown in FIG. 3 (c), a strip-shaped hook-and-loop fastener 12 is attached to the peripheral area of the back surface of each wooden flooring material 5a in a substantially square shape. A number of surface engaging members 7 (FIG. 2) made of hard hook-like protrusions are provided on the hook-and-loop fastener 12.
[0012]
A plurality of concave grooves 9 are formed along one side of the back surface of the wooden flooring material 5a. In the embodiment shown in FIG. 3 (c), the concave grooves 9 are formed in parallel to each other along a direction F perpendicular to one side of the long side of the wood flooring material 5a. These concave grooves 9 function to prevent deformation such as expansion, expansion and contraction, and twisting of the wood flooring material 5a.
[0013]
Further, uneven joint real parts 16 are formed on the four sides of each wooden flooring material 5a. As shown in FIG. 4, the joint real part 16 has a shape that allows play for expansion and expansion / contraction of the wooden flooring material 5 a and absorbs excessive expansion / contraction. In other words, when the wood flooring material 5a is joined, the lower convex portion 15a of the female fruit 15 hits the lower surface 14a of the male fruit 14, so that it is joined with play d. In the case of extension, the lower surface 14a of the male fruit 14 pushes the lower convex portion 15a of the female fruit 15 downward so that the wooden flooring materials 5a approach each other, so that no push-up or the like occurs. Further, when the shrinkage is excessive, the shrinkage is absorbed by the left and right overlap L between the male fruit 14 and the female fruit 15 so that the existing floor 17 can be prevented from being seen. In order to prevent the gaps from becoming conspicuous at the time of contraction, it is desirable that the upper surface 14b of the male fruit 14 is colored in the same or similar color as the surface color of the wood flooring material 5a.
[0014]
Next, when constructing the floor heating device, first, an electric heater wire, a soaking sheet 3, and a loop-shaped surface engaging member 6 are sequentially laminated and bonded on a heat insulating material 1 such as felt to form a sheet layer. The floor heating base material 4 is prepared. After that, as shown in FIG. 5, the floor heating base material 4 wound in a roll shape is spread and spread on the existing floor 17. At this time, the lower surface of the floor heating base material 4 is bonded to the existing floor 17 with the double-sided tape 80. In addition, a spacer mat 13 without an electric heater wire and a soaking sheet is laid on the floor portion without the floor heating base material 4. The spacer mat 13 is formed to have the same thickness as the floor heating base material 4, and it is possible to perform the construction up to the wall by placing the spacer mat 13 on a portion where the floor heating base material 4 is not provided. It can be done. Similar to the surface of the floor heating base material 4, a hook-and-loop fastener having a loop-shaped surface engaging member 6 (FIG. 2) is attached to the entire surface of the spacer mat 13.
[0015]
Thereafter, as shown in FIG. 6, a large number of wooden flooring materials 5 a are sequentially spread on the floor heating base material 4 and the spacer mat 13. At this time, as shown in FIG. 7A, a thin construction sheet 10 that is slightly larger than one woody flooring material 5a is placed on the floor heating base material 4, and the upper surface engaging member 7 is attached to the back surface. The wooden flooring material 5a is placed on the construction sheet 10, and the wooden flooring material 5a is slid in the direction indicated by arrows A and B in FIG. The position of the wood flooring material 5a is adjusted as shown. Thereafter, the construction sheet 10 is pulled out in the direction indicated by the arrow C in FIGS. Thereby, the upper and lower surface engaging members 6 and 7 can be engaged with each other for the first time, and the wooden flooring material 5 a can be easily fixed on the floor heating base material 4. In this way, a large number of wooden flooring materials 5a are sequentially applied in a staggered state so as to be staggered. By arranging the wooden flooring material 5a in a staggered manner, minute dimensional changes due to expansion and contraction can be evenly absorbed by each wooden flooring material 5a, and the gaps and push-ups can be made inconspicuous, and the elasticity It becomes possible to prevent such deformation.
[0016]
As described above, the floor heating base material 5 is fixed on the floor heating base material 4 using the detachable surface engaging members 6 and 7 instead of directly bonding the entire surface of the conventional adhesive, as described above. The installation and replacement of the finished floor material 5 with respect to the material 4 is easy, the wooden flooring finish can be done with a simple construction, and the construction can be performed in a short time. In addition, it can be easily installed when flooring the entire floor from wall to wall by retrofitting.
[0017]
Moreover, by joining a large number of wooden flooring materials 5a constituting the finished flooring 5 with the uneven joint real parts 16, the expansion and contraction of the wooden flooring material 5a can be dispersed and absorbed by the uneven joint real parts 16. . In other words, in the conventional fixing method using an adhesive, the expansion and contraction of the finished floor material concentrates on the weakly adhesive part due to the dispersion of the adhesion, the thermal expansion due to floor heating, or the finish floor material due to moisture absorption drying. In the present invention, the wooden flooring material 5a can be constructed without an adhesive, and at the same time, the expansion and contraction of the wooden flooring material 5a is made uneven as shown in FIG. Therefore, it is possible to reliably prevent the occurrence of gaps and push-up phenomenon of the wooden flooring material 5a. That is, since an adhesive such as a joint bond is not put into the joint real part 16, the joint real part 16 has a certain degree of freedom even after the construction, and the dimensional expansion and contraction of the wood flooring material 5a is performed by each joint real part 16. Dispersed and absorbed.
[0018]
Further, the finished flooring 5 is formed in a quadrangular shape in plan view, and a plurality of concave grooves 9 are formed in parallel to each other along one side of the wooden flooring 5a on the back surface of each wooden flooring 5a constituting the finished flooring 5. Therefore, the expansion and contraction of the wood flooring material 5a can be surely absorbed by the respective concave grooves 9, and deformation such as gaps, push-ups and twists can be prevented, and the wood flooring material 5a is formed in a rectangular shape. In this case, forming the concave groove 9 in a direction orthogonal to the long side direction makes the groove 9 more effective in preventing deformation such as expansion and contraction. Further, as shown in FIG. 3 (d), the band-shaped surface fastener 12 provided with the hook-shaped surface engaging member 7 is attached so as to cross over the plurality of grooves 9. The flooring material 5a can be prevented from being deformed up and down, and the handling strength of the flooring can be sufficiently maintained.
[0019]
Moreover, since the loop-shaped surface engaging member 6 is attached to substantially the entire surface of the floor heating base material 4 at the time of construction of the wood flooring material 5a, the wood flooring material 5a is positioned at any position of the floor heating base material 4. In addition, it is possible to freely attach the wooden flooring material 5a to the attachment position of the wood flooring material 5a. On the other hand, since the hook-shaped surface engaging member 7 is attached to the peripheral region on the back surface of the wood flooring material 5a, the upper surface engaging member 7 is arranged in a well-balanced manner, and the lower surface engaging member 6 can be prevented from being biased, and the wood flooring material 5a can be more completely prevented from generating gaps, push-ups, distortions, and the like. Since it is not fixed to 4, the wooden flooring material 5a can be easily peeled off. Further, since nails are not used, there is no need to worry about damaging the floor heating base material 4. Even if the floor heating device breaks down or the finished floor material 5 is damaged, the floor heating device can be easily replaced and the finished floor material 5 can be easily replaced, greatly improving workability during renovation. Can be improved. Furthermore, since the surface fasteners 11 and 12 having the surface engaging members 6 and 7 can be reused, the cost can be further reduced.
[0020]
In addition, since the lower surface engaging member 6 attached to the floor heating base material 4 is formed in a loop shape, the soft loop surface engaging member 6 is attached to the surface of the floor heating base material 4 in a large area. Therefore, the walking feeling is good when walking on the floor heating base material 4 at the time of construction, and the loop-shaped surface engaging member 6 is less likely to be crushed than the hook-shaped surface engaging member 7, so that the work can be performed with peace of mind. become able to. Moreover, since the thin and strong planar reinforcing member 8 such as a glass cloth is provided on the surface of the floor heating base material 4, even if the lower surface of the floor heating base material 4 is an elastic material such as felt, the wood flooring material 5a. It is possible to stop the horizontal movement of the heat insulating material 1, and the surface reinforcing member 8 can secure the thickness of the heat insulating material 1 to improve the soundproofing performance, and the heat insulating material 1 is formed of felt. In combination with this, the soundproofing effect is enhanced and the walking feeling of the floor after construction can be improved.
[0021]
In addition, when adjusting the position of the wooden flooring material 5a, the thin flooring sheet 10 is sandwiched between the floor heating base material 4 and the wooden flooring material 5a, thereby adjusting the position of the wooden flooring material 5a while sliding on the construction sheet 10. In addition, since it is possible to improve the joining accuracy, it is possible to perform floor construction even for an amateur without requiring specialized techniques, shortening the construction time, and realizing cost reduction. Furthermore, by laying a spacer mat 13 having the same thickness as the floor heating base material 4 in a place where the floor heating base material 4 is not laid, the construction up to the wall can be performed flush with each other. The entire floor can be spread from wall to wall, and the floor heating can be easily performed. In addition, by placing the spacer mat 13 on a portion where the floor heating base material 4 is not provided, the entire floor can be connected with the wooden flooring material 5a. In this case, the floor strength is as follows. Therefore, the floor heating base material 4 may be temporarily fixed to the existing floor 17 with the double-sided tape 80, and the existing floor 17 is not damaged. Further, since the electric heater wire and the soaking sheet 3 are not provided on the spacer mat 13, it can be easily cut according to the size of the site, the room size is not limited, and the finish is good.
[0022]
Furthermore, since the floor heating base material 4 is formed with three layers of soaking sheets, even if water is spilled, there is no risk of water reaching the existing floor 17 and the waterproofness can be improved. . If the soaking sheet 3 is placed in the spacer mat 13, the waterproof property of the entire floor can be easily increased. Moreover, since the heat insulating material 1 is formed of felt, the expansion and contraction of the wood flooring material 5a can also be absorbed by the heat insulating material 1, and the expansion and contraction absorption can be maintained. Further, by attaching the loop-shaped surface engaging member 6 integrally to the surface of the floor heating base material 4, there is also an advantage that the surface engaging member can be packed in a state where the floor heating base material 4 is wound. .
[0023]
On the other hand, at the end of the wall, cut the dimensions of the wooden flooring material 5a and the like so that a clearance of about 5 to 10 mm is formed between the wooden flooring material 5a and the existing baseboard 57 on the wall 56 side, The parting edge 20 shown in FIG. 8 (a) or FIG. 8 (b) is attached. The parting edge 20 is affixed from above the wooden flooring material 5a. FIG. 8A shows a case where the parting edge 20 is made of extruded PVC, and a substantially semi-circular bulging part 21 ′ attached to the end thereof is attached. FIG. 8B shows the parting edge. The case where the collar part 21 which has elasticity is integrally formed in the edge 20 is shown. In either case, the expansion and contraction of the flange portions 21 and 21 ′ can prevent the occurrence of heat expansion due to floor heating and the push-up phenomenon near the wall due to moisture drying. It is possible to eliminate the need to process the joints with high accuracy. Further, by providing the parting edge 20 as a separate part near the wall, it is not necessary to accurately cut the dimension of the finished flooring 5 in accordance with the dimension near the wall.
[0024]
FIG. 10 shows the power supply unit 25 of the floor heating base material 4. The power supply unit 25 is provided with a foldable narrow portion 32 between the main body portion 30 and the connection portion 31, and leans the connection portion case 33 connected to the narrow portion 32 against the wall. By installing, the appearance of the power supply unit 25 to the floor heating base material 4 can be finished in a shape like a baseboard. In the figure, 2 is a heating element (electric heater wire), and 2a is a bent portion. Thus, by making it into the shape of the baseboard provided in the wall side, and making a heater wire stand up by the wall side, it becomes unnecessary to provide the connection part 31 in the main-body part 30, and it becomes possible to make the main-body part 30 thin. Therefore, while maintaining soundproofing and heat insulation performance, it becomes possible to realize a thinness within 15 mm of the floor level, which is the standard of so-called barrier-free houses, and it is less likely to trip on the floor or hinder the opening and closing of the door. . Moreover, by providing the power supply unit 25 near the wall, it is possible to check the electrical performance of the floor heating base material 4 without removing the wooden flooring material 5a. Furthermore, as shown in FIG. 9, if the wiring duct 22 is provided adjacent to the connection case 33, the design can be made clear. In FIG. 9, 22 is a wiring duct, 23 is a power cord, and 24 is a controller.
[0025]

[0026]
On the other hand, the spacer mat for absorbing the level difference at the wall is made of the above-mentioned material (felt or the like) without the aluminum foil and the heater wire.

On the back of this wood flooring material, a belt-like surface fastener with a width of 20 mm in which 20 hook-shaped protrusions are provided on a polyester sheet (thickness 1 mm) with a 10 mm square is attached to both sides of a 10 cm width wood flooring material with an adhesive. Adhere with a length of 90 cm and reinforce with a tucker.
[0027]
The wood flooring material has been subjected to actual processing for joining both vertically and horizontally, but the joint portion (short side) in the longitudinal direction with large expansion and contraction is particularly shaped as shown in FIG. 4 to make it easier to absorb expansion and contraction. .
Then, a plurality of wooden flooring materials are shifted 45 cm in the length direction and alternately staggered and laid on the floor heating base material. At this time, a 150 μm-thick construction sheet (paper) impregnated with silicon is laid on the floor heating base material to cover the surface fastener provided with the loop-shaped surface engaging member, and the wooden flooring material is slid thereon. The position of the wood flooring material is adjusted while adjusting the joint, the construction sheet is removed, and the wood flooring material is pressed from above to engage the surface engaging members with each other.
[0028]

After placing the finished floor material on the material and adjusting the position of the finished floor material, the finished floor material is removed from the surface of the floor heating base material by removing the construction sheet and engaging the upper and lower surface engaging members with each other. Since it is fixed, the finished floor is slid on the construction sheet by sandwiching the construction sheet between the floor heating base material and the finished floor before engaging the upper and lower surface engaging members. Since it can be adjusted to increase the joining accuracy, it does not require specialized techniques, and floor work can be performed even by a non-skilled person, thereby reducing construction time and cost.In addition, the surface side of the floor heating base material can be reinforced with a planar reinforcing member, and even if the lower surface side of the floor heating base material is a heat insulating material such as felt, the horizontal movement of the finished floor material is maintained. It can be stopped, and the fear that the finished flooring material moves laterally during walking or the like can be eliminated, and the feeling of walking on the floor can be improved.
