Description

本発明は、暖房性能の向上と床の強度が保てるようにした床暖房パネルに関する。   The present invention relates to a floor heating panel that can improve heating performance and maintain floor strength.

図５（ａ）に示すように、電気式床暖房に用いる床暖房パネル１は、縦長さＬ（例えば１８１８ｍｍ…６尺）と横幅Ｗ（例えば３０３ｍｍ…１尺）と厚みＴ（例えば１２ｍｍ）とが規格化されていて、図５（ｂ）に示すように、床下地の上面に隙間無く縦横に敷き詰めるようになっている（特許文献１参照）。   As shown to Fig.5 (a), the floor heating panel 1 used for an electric floor heating is longitudinal length L (for example, 1818 mm ... 6 scale), width W (for example, 303 mm ... 1 scale), and thickness T (for example, 12 mm). Are standardized, and as shown in FIG. 5 (b), they are spread vertically and horizontally on the upper surface of the floor base (see Patent Document 1).

前記のような床暖房パネル１として、図５（ａ）のＢ−Ｂ線断面図である図６（ａ）の第１背景技術は、木質床材２の裏面に堀り込み部２ａを形成して、堀り込み部２ａの底面に、面状発熱体３を貼着するとともに、面状発熱体３の裏面に面状材（合板、発泡樹脂等）４を貼着するようにしている。なお、２ｃおよび２ｄは、床暖房パネル１を嵌め合い状態で敷き詰めるための雄および雌の実（さね）である。   As the floor heating panel 1 as described above, the first background art of FIG. 6 (a), which is a cross-sectional view taken along the line BB of FIG. 5 (a), forms a dug portion 2a on the back surface of the wooden flooring 2. Then, the sheet heating element 3 is adhered to the bottom surface of the dug portion 2a, and the sheet material (plywood, foamed resin, etc.) 4 is adhered to the back surface of the sheet heating element 3. . Reference numerals 2c and 2d are male and female fruits for spreading the floor heating panel 1 in a fitted state.

そして、木質床材２の厚さＴを１２ｍｍとすれば、木質床材２の裏面から３ｍｍ深さｔ１で堀り込み部２ａを堀り込んで、堀り込み部２ａの底面に、１ｍｍ厚みｔ２の面状発熱体３を貼着するとともに、面状発熱体３の裏面に２ｍｍ厚みｔ３の面状材４を貼着するようになっている。   If the thickness T of the wooden flooring 2 is 12 mm, the dug portion 2a is dug from the back surface of the wooden flooring 2 at a depth t1 of 3 mm, and the bottom of the dug portion 2a is 1 mm thick. While the planar heating element 3 of t2 is stuck, the planar material 4 of 2 mm thickness t3 is stuck to the back surface of the planar heating element 3.

図６（ｂ）の第２背景技術は、木質床材２の裏面から６ｍｍ深さｔ１で堀り込み部２ａを堀り込んで、堀り込み部２ａの底面に、１ｍｍ厚みｔ２の面状発熱体３を貼着するとともに、面状発熱体３の裏面に５ｍｍ厚みｔ３の真空断熱材８を配置して、木質床材２の裏面に、例えば厚み０．２ｍｍ程度のシート材（紙、樹脂、金属等）９を貼着することで、堀り込み部２ａを閉塞するようになっている。   In the second background art of FIG. 6B, a dug portion 2a is dug at a depth t1 of 6 mm from the back surface of the wooden flooring 2, and a 1 mm thickness t2 surface shape is formed on the bottom surface of the dug portion 2a. While sticking the heat generating body 3, the vacuum heat insulating material 8 of 5 mm thickness t3 is arrange | positioned at the back surface of the planar heat generating body 3, and the sheet material (paper, about 0.2 mm in thickness, for example on the back surface of the wooden flooring 2 is provided. By adhering 9 (resin, metal, etc.), the digging portion 2 a is closed.

背景技術１では、面状発熱体３の上に位置する木質床材２の厚みｔ６が９ｍｍであるから、昇温スピードが遅くて、上下放熱効率も悪いという問題がある。   In the background art 1, since the thickness t6 of the wooden flooring 2 positioned on the planar heating element 3 is 9 mm, there is a problem that the temperature raising speed is slow and the vertical heat dissipation efficiency is also poor.

これに対して、背景技術２では、面状発熱体３の上に位置する木質床材２の厚みｔ６が６ｍｍであることに加えて、真空断熱材８を配置することで木質床材２の裏面側方向への放熱が格段に抑制できるから、昇温スピードが早くなって、上下放熱効率も良くなる。
特開２００４−２４５５１８号公報 On the other hand, in the background art 2, in addition to the thickness t6 of the wooden flooring 2 positioned on the planar heating element 3 being 6 mm, the vacuum heat insulating material 8 is arranged to arrange the wooden flooring 2. Since heat radiation toward the back side can be remarkably suppressed, the temperature raising speed is increased and the vertical heat radiation efficiency is improved.
JP 2004-245518 A

しかしながら、背景技術２では、床暖房パネルの施工時に誤って釘等で真空断熱材に穴が開くと、断熱性能が発揮されなくなるとともに、面状発熱体３の上に位置する木質床材２の厚みｔ６が６ｍｍであるから、床を踏みつけたとき撓みやすくなる等の強度上の問題があった。   However, in Background Art 2, if a hole is accidentally opened in the vacuum heat insulating material with a nail or the like during construction of the floor heating panel, the heat insulating performance is not exhibited, and the wooden floor material 2 located on the planar heating element 3 is not provided. Since the thickness t6 is 6 mm, there is a problem in strength such as easy bending when the floor is stepped on.

本発明は、前記問題を解消するためになされたもので、真空断熱材を用いることで、昇温スピードが早くなって、上下放熱効率も良くなることで、暖房性能が向上して省エネにも優れるとともに、床暖房パネルの施工時に誤って真空断熱材に穴が開いても、その影響を最小限に止めることができ、かつ床の強度が充分に保てるようにした床暖房パネルを提供することを目的とするものである。   The present invention has been made to solve the above problems, and by using a vacuum heat insulating material, the temperature raising speed is increased and the vertical heat dissipation efficiency is improved, thereby improving the heating performance and saving energy. To provide a floor heating panel that is excellent in that it is possible to minimize the influence of a hole in the vacuum insulation material when it is accidentally opened during construction of the floor heating panel, and to maintain sufficient floor strength. It is intended.

前記課題を解決するために、本発明は、木質床材の裏面に形成した堀り込み部の底面に、面状発熱体を貼着する床暖房パネルにおいて、前記面状発熱体の裏面に複数枚の真空断熱材を横並びで配置し、各真空断熱材の間に桟材を配置したことを特徴とする床暖房パネルを提供するものである。   In order to solve the above problems, the present invention provides a floor heating panel in which a sheet heating element is attached to the bottom surface of a dug formed on the back surface of a wooden floor material. The present invention provides a floor heating panel in which a plurality of vacuum heat insulating materials are arranged side by side, and a crosspiece is disposed between the vacuum heat insulating materials.

真空断熱材が脱落しないように保持するために、前記桟材の下面に凸部を形成して、この凸部と面状発熱体との間に、真空断熱材の端部を挿入する構成とすることが好ましい。   In order to keep the vacuum heat insulating material from falling off, a convex portion is formed on the lower surface of the crosspiece, and an end portion of the vacuum heat insulating material is inserted between the convex portion and the planar heating element. It is preferable to do.

真空断熱材が脱落しないように保持するために、前記桟材の側面に凹部を形成して、この凹部に真空断熱材の端部を挿入する構成とすることが好ましい。   In order to keep the vacuum heat insulating material from falling off, it is preferable to form a recess in the side surface of the crosspiece and insert the end of the vacuum heat insulating material into the recess.

本発明によれば、前記背景技術２の構成を基本として、面状発熱体の裏面に複数枚の真空断熱材を横並びで配置し、各真空断熱材の間に桟材を配置することにより、背景技術２と同様に、面状発熱体の上に位置する木質床材の厚みが背景技術１と比べて薄くなる（例えば厚みｔ６が６ｍｍ）ので、昇温スピードが早くなって（快適性）、上下放熱効率も良くなることで（省エネ性）、暖房性能が向上するようになる。   According to the present invention, on the basis of the configuration of the background art 2, a plurality of vacuum heat insulating materials are arranged side by side on the back surface of the planar heating element, and a crosspiece is arranged between the vacuum heat insulating materials. Similar to the background art 2, the thickness of the wooden floor located on the planar heating element is thinner than the background art 1 (for example, the thickness t6 is 6 mm), so the temperature raising speed is increased (comfort). The heat dissipation efficiency is improved (energy saving), and the heating performance is improved.

また、複数枚の真空断熱材を横並びで配置したから、面状発熱体の裏面方向への放熱が格段に抑制できるので、暖房性能がより向上するようになるとともに、床下地と床暖房パネルとの間に介在させる断熱材を省略することが可能になる。さらに、床暖房パネルの施工時に誤って釘等で複数枚の真空断熱材の一部に穴が開いて断熱性能が発揮されないことがあったとしても、その影響が床暖房パネル全体に及ぶことを未然に避けることができる。   In addition, since a plurality of vacuum heat insulating materials are arranged side by side, heat radiation toward the back side of the planar heating element can be remarkably suppressed, so that the heating performance is further improved, and the floor substrate and the floor heating panel It becomes possible to omit the heat insulating material interposed between the two. Furthermore, even if the floor heating panel is accidentally opened with holes such as nails in some of the vacuum insulation materials and the insulation performance may not be demonstrated, the effect will affect the entire floor heating panel. It can be avoided in advance.

さらにまた、各真空断熱材の間に補強部材としての桟材を配置したから、床を踏みつけたとき撓みにくくなって、床の強度が充分に保てるようになる。   Furthermore, since a crosspiece as a reinforcing member is disposed between the vacuum heat insulating materials, it becomes difficult to bend when the floor is stepped on, and the strength of the floor can be sufficiently maintained.

以下、本発明を実施するための最良の形態について、図面を参照しながら詳細に説明する。なお、背景技術と同一構成・作用の箇所は、同一番号を付して詳細な説明を省略する。   Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings. Note that portions having the same configuration and operation as those of the background art are denoted by the same reference numerals, and detailed description thereof is omitted.

図１（ａ）は、図５（ａ）のＡ−Ａ線横断面に相当する床暖房パネル６の断面図、図１（ｂ）は、床暖房パネル６の底面（裏面）図である。   FIG. 1A is a cross-sectional view of the floor heating panel 6 corresponding to the AA line cross section of FIG. 5A, and FIG. 1B is a bottom (back) view of the floor heating panel 6.

図２にも示すように、木質床材２の裏面に堀り込み部２ａを形成して、堀り込み部２ａの底面に、面状発熱体３を貼着するようにしている。この貼着は、例えばホットメルト接着剤で接着することができる。なお、２ｅ，２ｆは、床暖房パネル連結用のリード線の端末のコネクタ用の窪みである。   As shown in FIG. 2, a dug portion 2 a is formed on the back surface of the wooden flooring 2, and the planar heating element 3 is adhered to the bottom surface of the dug portion 2 a. This sticking can be performed with, for example, a hot melt adhesive. Reference numerals 2e and 2f are recesses for the connector of the terminal of the lead wire for connecting the floor heating panel.

そして、木質床材２の厚さＴを１２ｍｍとすれば、図６（ｂ）の背景技術２と同様に、木質床材２の裏面から６ｍｍ深さｔ１で堀り込み部２ａを堀り込んで、堀り込み部２ａの底面に、１ｍｍ厚みｔ２の面状発熱体３を貼着するとともに、面状発熱体３の裏面に５ｍｍ厚みｔ３の複数枚（本例では６枚）の真空断熱材８を長さ方向に横並びで配置している。この真空断熱材８は、芯材をガスバリア性を有する包装材で包装したものである。   If the thickness T of the wooden flooring 2 is 12 mm, the dug portion 2a is dug at a depth t1 of 6 mm from the back surface of the wooden flooring 2 as in the background art 2 of FIG. Then, the sheet heating element 3 having a thickness of 1 mm t2 is adhered to the bottom surface of the dug portion 2a, and a plurality of (6 sheets in this example) vacuum insulation of 5 mm thickness t3 is attached to the back surface of the sheet heating element 3. The materials 8 are arranged side by side in the length direction. The vacuum heat insulating material 8 is obtained by packaging a core material with a packaging material having a gas barrier property.

また、木質床材２の裏面に、例えば厚み０．２ｍｍ程度のシート材（紙、樹脂、金属等）９を貼着することで、堀り込み部２ａを閉塞するようになっている。そして、各真空断熱材８の間に複数本（本例では５本）の横桟材１０を配置している。   Further, by sticking a sheet material (paper, resin, metal, etc.) 9 having a thickness of about 0.2 mm, for example, to the back surface of the wooden floor material 2, the dug portion 2a is closed. A plurality of (five in this example) horizontal crosspieces 10 are arranged between the vacuum heat insulating materials 8.

前記のような床暖房パネル６であれば、前記背景技術２の構成を基本として、面状発熱体３の裏面に複数枚の真空断熱材８を横並びで配置し、各真空断熱材８の間に横桟材１０を配置することにより、背景技術２と同様に、面状発熱体３の上に位置する木質床材２の厚みが背景技術１と比べて薄くなる（例えば厚みｔ６が６ｍｍ）ので、昇温スピードが早くなって（快適性）、上下放熱効率も良くなることで（省エネ性）、暖房性能が向上するようになる。   In the case of the floor heating panel 6 as described above, based on the configuration of the background art 2, a plurality of vacuum heat insulating materials 8 are arranged side by side on the back surface of the planar heating element 3, and the space between the vacuum heat insulating materials 8 is determined. By disposing the crosspiece 10 in the same manner as in the background art 2, the thickness of the wooden flooring 2 positioned on the planar heating element 3 is thinner than that in the background art 1 (for example, the thickness t6 is 6 mm). Therefore, the heating speed is improved (comfort) and the heat dissipation efficiency is improved (energy saving), so that the heating performance is improved.

また、複数枚の真空断熱材８を横並びで配置したから、面状発熱体３の裏面方向への放熱が格段に抑制できるので、暖房性能がより向上するようになるとともに、床下地と床暖房パネル６との間に介在させる断熱材を省略することが可能になる。   Further, since the plurality of vacuum heat insulating materials 8 are arranged side by side, the heat radiation toward the back surface of the planar heating element 3 can be remarkably suppressed, so that the heating performance is further improved and the floor base and the floor heating are further improved. It is possible to omit a heat insulating material interposed between the panel 6 and the panel 6.

さらに、床暖房パネル６の施工時に誤って釘等で複数枚の真空断熱材８の一部に穴が開いて断熱性能が発揮されないことがあったとしても、その影響が床暖房パネル６全体に及ぶことを未然に避けることができる。   Furthermore, even when the floor heating panel 6 is constructed by mistake, nails or the like may cause a hole in a part of the plurality of vacuum heat insulating materials 8 and the heat insulation performance may not be exhibited. It can be avoided in advance.

さらにまた、各真空断熱材８の間に補強部材としての横桟材１０を配置したから、床を踏みつけたとき撓みにくくなって、床の強度が充分に保てるようになる。   Furthermore, since the crosspieces 10 as the reinforcing members are disposed between the vacuum heat insulating materials 8, the floor is less likely to bend when the floor is stepped on, so that the strength of the floor can be sufficiently maintained.

図３（ａ）に示すように、前記横桟材１０の下面に逆Ｔ字状の凸部１０ａを形成して、この凸部１０ａと面状発熱体３との間に、真空断熱材８の端部を挿入することにより、真空断熱材８が脱落しないように保持できるので、組み込みが容易になって生産性が向上するとともに、木質床材２の裏面にシート材９を貼着して堀り込み部２ａを閉塞する場合には、シート材９を横桟材１０の凸部１０ａにも貼着できるので、シート材９の形状安定性も向上するようになる。   As shown in FIG. 3A, an inverted T-shaped convex portion 10 a is formed on the lower surface of the horizontal crosspiece 10, and the vacuum heat insulating material 8 is provided between the convex portion 10 a and the planar heating element 3. Since the vacuum heat insulating material 8 can be held so as not to drop off by inserting the end portion of the metal sheet, assembling becomes easy and productivity is improved, and a sheet material 9 is attached to the back surface of the wooden flooring 2. In the case where the dug portion 2a is closed, the sheet material 9 can be adhered to the convex portion 10a of the horizontal rail member 10, so that the shape stability of the sheet material 9 is also improved.

図３（ｂ）に示すように、前記横桟材１０の側面にスリット状の凹部１０ｂを形成して、この凹部１０ｂに真空断熱材８の端部（芯材の包装材を厚み方向の中間部で熱溶着することにより生ずるひれ状の硬い熱溶着端部）を挿入することにより、真空断熱材８が脱落しないように保持できるので、組み込みが容易になって生産性が向上するとともに、横桟材１０の横幅が広くなるので、床の強度が増加するうえに、木質床材２の裏面にシート材９を貼着して堀り込み部２ａを閉塞する場合には、シート材９を広い横幅の横桟材１０にも貼着できるので、シート材９の形状安定性も向上するようになる。   As shown in FIG. 3 (b), a slit-like recess 10b is formed on the side surface of the horizontal beam member 10, and the end of the vacuum heat insulating material 8 (the core packaging material is intermediate in the thickness direction) in the recess 10b. By inserting a fin-like hard heat-welding end portion generated by heat-welding at the portion, the vacuum heat insulating material 8 can be held so as not to drop off, so that assembling becomes easy and productivity is improved. Since the width of the crosspiece 10 is increased, the strength of the floor is increased, and in addition, when the sheet material 9 is adhered to the back surface of the wooden floor material 2 to close the dug portion 2a, the sheet material 9 is Since the sheet can be attached to the wide crosspiece 10 having a wide width, the shape stability of the sheet material 9 is also improved.

前記実施形態では、面状発熱体３の裏面に６枚の真空断熱材８を長さ方向に横並びで配置して、各真空断熱材８の間に５本の横桟材１０を配置したものであったが、図４（ａ）（ｂ）に示すように、面状発熱体３の裏面に２枚の真空断熱材８を幅方向に横並びで配置して、各真空断熱材８の間に１本の縦桟材１１を配置したものでも良い。また、図４（ｃ）（ｄ）に示すように、面状発熱体３の裏面に１２枚の真空断熱材８を長さ方向および幅方向に横並びで配置して、各真空断熱材８の間に１本の縦桟材１１と１０本の横桟材１０を配置したものであっても良い。   In the embodiment, six vacuum heat insulating materials 8 are arranged side by side in the length direction on the back surface of the planar heating element 3, and five horizontal beam members 10 are arranged between the vacuum heat insulating materials 8. However, as shown in FIGS. 4 (a) and 4 (b), two vacuum heat insulating materials 8 are arranged side by side in the width direction on the back surface of the planar heating element 3, and Alternatively, a single vertical crosspiece 11 may be disposed. Further, as shown in FIGS. 4C and 4D, twelve vacuum heat insulating materials 8 are arranged side by side in the length direction and the width direction on the back surface of the planar heating element 3, and each of the vacuum heat insulating materials 8 is arranged. One vertical crosspiece 11 and ten horizontal crosspieces 10 may be disposed between them.
