Description

【0001】
【産業上の利用分野】
この発明は、床暖房パネル構造体に関する。
【0002】
【従来の技術】
従来より、工場生産を行うことによって現場での床構築作業の負担を軽減することができるものとして、所定寸法の床下地板の裏面に根太部材を所定間隔で設けた床パネルが知られている。この床パネルは、建屋の床骨組を成す大引き上に当該大引きに対して前記根太部材が直交するようにして配置され、この配置後に床仕上げ板等が設けられることになる。また、従来より、面状ヒーターなどの熱供与体、更には蓄熱材や断熱材を組み込んだ床暖房構造が提案されいる。
【0003】
【発明が解決しようとする課題】
しかしながら、上記床暖房構造を上述した床パネルに組み込んだ構造とし且つかかる構造を得る上での作業の容易化や効率化等を実現した提案はなされていない。
【0004】
この発明は、床板材の裏面に根太部材を所定間隔で設けた床パネルに床暖房構造を組み入れたものとし、かかる構造を得る上での作業の容易化や効率化、更には修理時や廃棄時の解体・分別の容易化が図れる床暖房パネル構造体を提供することを目的とする。
【0005】
【課題を解決するための手段】
この発明にかかる床暖房パネル構造体は、上記の課題を解決するために、床板材の裏面に根太部材が所定間隔で設けられ、少なくとも熱供与体を有して成る暖房ユニットが前記根太部材間に配置され、前記暖房ユニットを覆って前記根太部材の下面と略面一となるように第1の断熱材が設けられており、前記第1の断熱材及び前記根太部材の下面を覆うように第2の断熱材が設けられた床暖房パネル構造体であって、前記第2の断熱材の裏面には楔部を有する係止具が前記楔部を第2の断熱材に差し込んで設けられ、前記係止具に形成された貫通穴を介してビス又は釘が挿入され、このビス又は釘が前記根太部材に装着されていることを特徴とする。
【0006】
上記の構成であれば、前記係止具に形成された貫通穴を介して挿入されたビス又は釘が前記根太部材に装着されたことで、第2の断熱材にビス等による局所的な大きな力が加わらずに第2の断熱材の固定が行われることになる。接着剤による固定ではないため、例えば修理時などでの解体や再組み立てが容易である。前記係止具は単なる平板部材ではなく、楔部を有してこれが第2の断熱材に差し込んでいることにより、第2の断熱材の位置ずれなどが回避される。
【0007】
前記第2の断熱材には前記根太部材に対応した位置に凹部が形成されており、この凹部に前記係止具が装着されていてもよい。前記凹部が存在することにより、ビスの頭部が第2の断熱材の面から出てしまうこともなく、見栄えもよい。また、前記凹部が係止具装着位置の目印にもなり、作業性が向上する。
【0008】
また、この発明の床暖房パネル構造体は、床板材の裏面に根太部材が所定間隔で設けられ、少なくとも熱供与体を有して成る暖房ユニットが前記根太部材間に配置され、前記暖房ユニットを覆って前記根太部材の下面と略面一となるように第1の断熱材が設けられており、前記第1の断熱材及び前記根太部材の下面を覆うように第2の断熱材が設けられた床暖房パネル構造体であって、第1の断熱材と前記第2の断熱材との対面箇所には板状体であってその表裏両面側に楔部を有する係止具が前記楔部を前記第1の断熱材と前記第2の断熱材に差し込んで設けられていることを特徴とする。
【0009】
上記の構成であれば、前記係止具がその表裏両面側の楔部を前記第1の断熱材と前記第2の断熱材に差し込んで設けられているため、第1の断熱材と前記第2の断熱材との相対的な位置ずれが防止される。接着剤による位置ずれ防止ではないため、例えば修理時などでの解体や再組み立てが容易である。
【0010】
前記係止具は略四角形状を成し、その対角の二隅が表側に屈曲されて表側の楔部を成し、他の対角の二隅が裏側に屈曲されて裏側の楔部を成すのがよい。
【0011】
また、この発明の床暖房パネル構造体は、床板材の裏面に根太部材が所定間隔で設けられ、少なくとも熱供与体を有して成る暖房ユニットが前記根太部材間に配置され、前記暖房ユニットを覆って前記根太部材の下面と略面一となるように第1の断熱材が設けられており、前記第1の断熱材及び前記根太部材の下面を覆うように第2の断熱材が設けられた床暖房パネル構造体であって、楔部を有する係止具が前記根太部材に代わって暖房ユニットの側面側を支持するものとして前記床板材の縁部に固定されており、前記楔部は第1の断熱材に差し込んであることを特徴とする。
【0012】
上記の構成であれば、隣に位置することになる他の床暖房パネル構造体における根太部材との係合領域が前記係止具が固定されている箇所において形成されると共に、前記係止具にて暖房ユニットの側面支持が行え、更には、前記第1の楔部による第1の断熱材の保持及び前記第2の楔部による第2の断熱材の保持が行われることになる。接着剤による断熱材保持ではないため、例えば修理時などでの解体や再組み立てが容易である
【0013】
前記係止具は第1の楔部を第1の断熱材の下面に差し込み、第2の楔部を第2の断熱材の側面に差し込んであるのがよい。
【0014】
また、この発明の床暖房パネル構造体は、床板材の裏面に根太部材が所定間隔で設けられ、少なくとも熱供与体を有して成る暖房ユニットが前記根太部材間に配置され、前記暖房ユニットに被せられて前記根太部材の下面と略面一となるように第1の断熱材が設けられており、前記第1の断熱材及び前記根太部材の下面を覆うように第2の断熱材が設けられた床暖房パネル構造体であって、断面コ字形状を有し且つ楔部を有する係止具が、断面コ字形状における一方の水平部を第1の断熱材と暖房ユニットとの間に位置させ、他方の水平部を暖房ユニットと床板材との間に位置させて暖房ユニット側面近傍位置に設けられており、前記楔部を第1の断熱材に差し込んであることを特徴とする。
【0015】
上記の構成であれば、前記係止具によって第1の断熱材上で暖房ユニットはその側面側が支持されることになり、暖房ユニットと第1の断熱材とのユニット化によって組み立て性が向上する。また、暖房ユニットの配置空間の高さを前記係止具が規定することにもなり、暖房ユニットへの不所望な力の加わりや床板材と暖房ユニットとの隙間発生を極力回避できることになる。
【0016】
前記係止具の楔部は前記一方の水平部の先端側に形成されているのがよい。
【0017】
前記係止具は断面コ字形状における垂直部を第1の断熱材の縁面と略面一にして設けられているのがよい。これによれば、第1の断熱材を箱型に成形する場合に比べて暖房ユニットの収容スペースを大きくすることができ、大きな暖房ユニットを用いることができる。
【0018】
これら床暖房パネル構造体において用いる係止具は、金属板の折り曲げ又は折り曲げと剪断にて加工されて成るものもよい。
【0019】
【発明の実施の形態】
以下、この発明の実施形態の床暖房パネル構造体を図1乃至図10に基づいて説明する。
【0020】
図1はこの実施形態の床暖房パネル構造体1を示した断面図であり、同図(a)は全体を示し、同図(b)は一部を拡大して示している。床下地板2の裏面に根太部材3…が所定間隔で設けられ、面状ヒーター4とこれを両側から挟み込むように設けられた潜熱蓄熱材5・5とを有して成る蓄熱ユニット6が前記根太部材3・3間に配置されている。そして、前記蓄熱ユニット6を覆って前記根太部材3の下面と略面一となるように第1の断熱材としてのウレタン7が設けられており、前記ウレタン及び前記根太部材3の下面を覆うように第2の断熱材としてのスチレンフォーム8が設けられている。前記根太部材3…のうちの最も端側の根太部材3は床下地板2の縁から幾分はみ出して設けられ、前記端と反対側の端においては、蓄熱ユニット6の側面からの床下地板2の端のはみ出し量を前記根太部材3のはみ出し量に対応させている。床下地板2の前記はみ出し部分には、後述する第3の金具12が設けられている。
【0021】
前記スチレンフォーム8の下面(図においては上側)には前記根太部材3に対応した位置に凹部8aが形成されており、この凹部8aに第1の金具9が装着されている。第1の金具9は、図2に示すように、略正方形の板状体であり、その四隅部が同方向に屈曲形成されることで楔部9aを成している。第1の金具9は、前記凹部8a内において楔部9aをスチレンフォーム8に差し込んで設けられている。前記第1の金具9の中央部には貫通穴9bが形成されている。この貫通穴9bを介してビス10が挿入され、このビス10の先端部が前記根太部材3にねじ込まれることでスチレンフォーム8の固定が行われている。
【0022】
ウレタン7とスチレンフォーム8との対面箇所には第2の金具11が設けられている。この第2の金具11は、図3に示すように、略長方形の板状体であり、その対角の二隅部が上方向に屈曲形成されることで上側楔部11aを成し、他の対角の二隅部が下方向に屈曲形成されることで下側楔部11bを成している。この第2の金具11は、上側楔部11aをウレタン7に差し込み、下側楔部11bをスチレンフォーム8に差し込んでいる。
【0023】
第3の金具12は、前記根太部材3に代わって端位置の蓄熱ユニット6の側面側を支持するものとして前記床下地板2の縁にビス13によって固定されている。第3の金具12は、図4に示すように、前記ビス13が装着される水平部分に対して立ち上がる垂直部分が剪断・屈曲されることで第1の楔部12aと第2の楔部12bとを有する。第1の楔部12aは、前記垂直部分に平行に下方に向いており、第2の楔部12bは前記垂直部分に直交する方向(水平方向)に向いている。そして、第1の楔部12aはウレタン7の下面に差し込まれ、第2の楔部12bはスチレンフォーム8の側面に差し込まれている。
【0024】
また、蓄熱ユニット6の側面側には第4の金具14が設けられている。この第4の金具14は、図5に示すように、広幅片部14aと細幅片部14bを有する断面略コ字形状を成し且つ前記広幅片部14aの先端側に垂直下方向に突出する楔部14cを有している。そして、この第4の金具14は前記楔部14cをウレタン7に差し込み、広幅片部14aをウレタン7と蓄熱ユニット6との間に位置させ、細幅片部14bを蓄熱ユニット6と床下地板2との間に位置させている。そして、この第4の金具14の装着においては、その垂直部がウレタン7の縁面と略面一となるようにしている。
【0025】
次に、上記床暖房パネル構造体1の組み立て工程及び据付について図6乃至図10に基づいて説明していく。
【0026】
まず、図6(a)に示すように、ウレタン7の両縁に第4の金具14…を装着する。すなわち、第4の金具14…の楔部14cをウレタン7の両縁部に差し込む。この後に蓄熱ユニット6をウレタン7上に配置する。蓄熱ユニット6は前記第4の金具14…によって側面側を支持されてウレタン7上に保持されたものとなる。ウレタン7にはコード挿通用の穴が形成されており、この穴に蓄熱ユニット6から引き出されたコード(VVF:フラット型ビニル絶縁ビニルシースケーブル)を挿通しておく。また、床下地板2上には根太部材3…を固定しておく。そして、同図(b)に示すように、ウレタン7が装着された蓄熱ユニット6を根太部材3・3間に配置していく。
【0027】
そして、図7(a)に示すように、全ての蓄熱ユニット6を配置したら、次には、同図(b)に示すように、第3の金具12を床下地板2の縁にビス13によって固定していく。このとき、第3の金具12の第1の楔部12aをウレタン7の下面に差し込んでおく。また、前記コードをコネクタ15に接続しておく。
【0028】
次に、図8(a)(b)に示すように、スチレンフォーム8の一方の面(ウレタン7に向かい合う面)に第2の金具11を装着しておき、かかるスチレンフォーム8の側面を第3の金具12の第2の楔部12bに押し当て、第2の楔部12bがスチレンフォーム8の側面に差し込まれた状態でスチレンフォーム8をウレタン7及び根太部材3…の下面に対面させて置く。
【0029】
そして、図9に示すように、スチレンフォーム8の凹部8aに第1の金具9を装着し、第1の金具9の貫通穴9bを介してビス10を挿入し、このビス10の先端部を前記根太部材3にねじ込む。また、スチレンフォーム8やウレタン7の側面にはEPT(エチレンプロピレンテルポリマー)テープ16を貼り付ける。以上説明した工程により、床暖房パネル構造体1が得られる。
【0030】
図10は床暖房パネル構造体1…の据付の様子を示した斜視図である。図においては、床暖房パネル構造体1…は床骨組となる鋼製の大引き20・20間に配置される。床暖房パネル構造体1におけるスチレンフォーム8については、大引き20・20の内縁間隔に対応しており、床暖房パネル構造体1における他の構造部分については、大引き20・20の中心線間隔に対応している。床暖房パネル構造体1は、その根太部材3…が大引き20に対して直交するようにして配置される。また、この配置に際してコネクタ15・15同士を接続する。床暖房パネル構造体1…の配置後に図示しない床仕上げ板等を設ける。
【0031】
以上説明したように、スチレンフォーム8には前記根太部材3の配置に対応した位置に凹部8aが形成されており、第1の金具9は、前記凹部8a内において楔部9aをスチレンフォーム8に差し込んで設けられている。前記第1の金具9の貫通穴9bを介してビス10が挿入され、このビス10の先端部が前記根太部材3にねじ込まれていることでスチレンフォーム8の固定が行われている。このため、スチレンフォーム8にビス10による局所的な大きな力が加わらずにスチレンフォーム8の固定が行われることになる。また、接着剤による固定ではないため、例えば修理時などでの解体や再組み立てが容易である。第1の金具9は単なる平板部材ではなく、楔部9aを有してこれがスチレンフォーム8に差し込んでいることにより、スチレンフォーム8の位置ずれなどが回避される。前記凹部8aが存在することにより、ビス10の頭部がスチレンフォーム8の面から出てしまうこともなく、見栄えもよい。また、前記凹部8aが第1の金具9の装着位置の目印にもなり、作業性が向上する。なお、第1の金具9はその四隅を屈曲させて楔部9aとしたが、これに限るものではなく、例えば、辺部の中央部を剪断・屈曲して楔部とすることができる。また、一枚の板を加工して得ることに限らず、板部材に楔部を接着や溶接等によって得たものでもよい。
【0032】
また、第2の金具11がその表裏両面側の楔部11a・11bをウレタン7とスチレンフォーム8に差し込んで設けられているため、ウレタン7とスチレンフォーム8との相対的な位置ずれが防止される。接着剤による位置ずれ防止ではないため、例えば修理時などでの解体や再組み立てが容易である。なお、第2の金具11はその四隅を屈曲させて楔部11a・11bとしたが、これに限るものではなく、例えば、辺部の中央部を剪断・屈曲して楔部とすることができる。また、一枚の板を加工して得ることに限らず、板部材に楔部を接着や溶接等によって得たものでもよい。
【0033】
また、第3の金具12が前記根太部材3に代わって蓄熱ユニット6の側面側を支持するものとして前記床下地板2の縁部に固定されており、第1の楔部12aはウレタン7の下面に差し込んであり、第2の楔部12bはスチレンフォーム8の側面に差し込んであるから、隣に位置することになる他の床暖房パネル構造体1における根太部材3の係合領域が前記第3の金具12が固定されている箇所において形成されると共に、前記第3の金具12と自身側の根太部材3との間での蓄熱ユニット6の側面支持が行え、更には、前記第1の楔部12aによるウレタン7の保持及び前記第2の楔部12bによるスチレンフォーム8の保持が行われることになる。接着剤による断熱材保持ではないため、例えば修理時などでの解体や再組み立てが容易である。なお、第3の金具12はその第1の楔部12aをウレタン7の下面に差し込み、第2の楔部12bをスチレンフォーム8の側面に差し込むものとしたが、これに限るものではない。また、一枚の板を加工して得ることに限らず、板部材に楔部を接着或いは溶接等してもよい。
【0034】
また、第4の金具14が、断面コ字形状における一方の片部14aをウレタン7と蓄熱ユニット6との間に位置させ、他方の片部14bを蓄熱ユニット6と床下地板2との間に位置させて蓄熱ユニット側面近傍位置に設けられており、楔部14cをウレタン7に差し込んでいるので、前記第4の金具14によってウレタン7上で蓄熱ユニット6はその側面側が支持されることになり、蓄熱ユニット6とウレタン7とのユニット化によって組み立て性が向上する。また、蓄熱ユニット6の配置空間の高さを前記第4の金具14が規定することにもなり、蓄熱ユニット6への不所望な力の加わりや床下地板2と蓄熱ユニット6との隙間発生を極力回避できることになる。また、第4の金具14における垂直部はウレタン7の縁面と略面一になっており、ウレタン7を箱型に成形する場合に比べて蓄熱ユニット6の収容スペースを大きくすることができ、大きな蓄熱ユニットを用いることができる。
【0035】
なお、上記実施形態においては、面状ヒーター4とこれを両側から挟み込むように設けられた潜熱蓄熱材5・5とを有して成る蓄熱ユニット6を暖房ユニットとして例示したが、蓄熱材を有しない暖房ユニットを用いてもよい。また、第3の金具12として第2の楔部12bを有するものを示したが、第2の楔部12bを有しない構成としてもよい。また、熱供与体を面状ヒーターとした構成を示したが、熱供与体を温水配管とする構成にもかかる発明を適用することができる。また、各金具においては楔部に返しを設けた構造としてもよい。また、断熱材についても、ウレタンやスチレンに限らず、他の素材を用いることができる。また、接着剤は望ましくないが、比較的剥離が容易である両面テープを例えばウレタン7と蓄熱ユニット6との間に設けてもよいものである。
【0036】
【発明の効果】
以上説明したように、この発明によれば、床板材の裏面に根太部材を所定間隔で設けた床パネルに床暖房構造を組み入れたものとし、かかる構造を得る上での作業の容易化や効率化、更には修理時や廃棄時の解体・分別の容易化が図れる等の諸効果を奏する。

Since the second wedge portion 12b is inserted into the side surface of the styrene foam 8, the engagement region of the joist member 3 in the other floor heating panel structure 1 to be located next to the third wedge portion 12b is the third region. And the side wall of the heat storage unit 6 can be supported between the third metal fitting 12 and the joist member 3 on its own side. Furthermore, the first wedge The urethane 7 is held by the portion 12a and the styrene foam 8 is held by the second wedge portion 12b. Since the heat insulating material is not held by an adhesive, disassembly and reassembly during repair, for example, is easy. In addition, although the 3rd metal fitting 12 shall insert the 1st wedge part 12a in the lower surface of urethane 7, and shall insert the 2nd wedge part 12b in the side surface of the styrene foam 8, it does not restrict to this. Further, the present invention is not limited to processing a single plate, and a wedge portion may be bonded or welded to the plate member.
[0034]
Further, the fourth metal fitting 14 has one piece 14a in a U-shaped cross section located between the urethane 7 and the heat storage unit 6, and the other piece 14b is placed between the heat storage unit 6 and the floor base plate 2. Since the wedge portion 14c is inserted into the urethane 7, the side surface of the heat storage unit 6 is supported on the urethane 7 by the fourth metal fitting 14. The unitability of the heat storage unit 6 and the urethane 7 improves assemblability. In addition, the fourth metal fitting 14 defines the height of the space in which the heat storage unit 6 is arranged, and an undesired force is applied to the heat storage unit 6 and a gap is generated between the floor base plate 2 and the heat storage unit 6. It can be avoided as much as possible. Further, the vertical portion of the fourth metal fitting 14 is substantially flush with the edge surface of the urethane 7, and the storage space of the heat storage unit 6 can be increased compared to the case where the urethane 7 is molded into a box shape. A large heat storage unit can be used.

In the above embodiment, the heat storage unit 6 including the planar heater 4 and the latent heat storage materials 5 and 5 provided so as to sandwich the sheet heater 4 from both sides is exemplified as the heating unit. A non-heating unit may be used. Moreover, although what has the 2nd wedge part 12b was shown as the 3rd metal fitting 12, it is good also as a structure which does not have the 2nd wedge part 12b. Moreover, although the structure which used the heat donor as the planar heater was shown, this invention can be applied also to the structure which uses a heat donor as a hot water piping. In addition, each metal fitting may have a structure in which a wedge is provided with a barb. Moreover, about a heat insulating material, not only urethane and styrene but another raw material can be used. Further, although an adhesive is not desirable, a double-sided tape that is relatively easy to peel may be provided between the urethane 7 and the heat storage unit 6, for example.
