Description

本発明は、住宅等の電気式暖房床システムに使用される暖房床パネルに関し、特に、暖房床パネルの表面部分が膨出状に変形するのを抑制する技術に関する。 The present invention relates to a heating floor panel used in an electric heating floor system such as a house, and more particularly to a technique for suppressing the surface portion of the heating floor panel from being deformed into a bulging shape.

従来より、この種の暖房床パネルとして、特許文献１に示されるものが知られている。このものでは、鉱物質繊維製板状体からなる断熱材の表面に型押し成形により所定の配線形状にヒータ線収納溝を形成する一方、予め、ヒータ線を断熱材のヒータ線収納溝の配線形状に合致する形状に形成しておいて、そのヒータ線収納溝に収納し、その断熱材のヒータ線収納溝側に熱伝導性板材よりなる均熱板をヒータ線と接して設けることで、埋込パネル部材を形成する。一方、裏面に周辺部を残した凹陥状の空洞部が形成された外殻部材を設け、この外殻部材の空洞部内に上記埋込パネル部材が均熱板を床面材側に向けて組み込まれている。 Conventionally, what is shown by patent document 1 is known as this kind of a heating floor panel. In this case, the heater wire storage groove is formed in a predetermined wiring shape by stamping on the surface of the heat insulating material made of a mineral fiber plate, and the heater wire is previously wired in the heater wire storage groove of the heat insulating material. By forming it in a shape that matches the shape, storing it in the heater wire storage groove, and providing a heat equalizing plate made of a heat conductive plate on the heater wire storage groove side of the heat insulating material in contact with the heater wire, An embedded panel member is formed. On the other hand, an outer shell member is formed in which a recessed hollow portion is formed with the peripheral portion remaining on the back surface, and the embedded panel member is incorporated into the hollow portion of the outer shell member with the heat equalizing plate facing the floor material side. It is.

そして、このような暖房床パネルは床下地材に対し、接着剤で接着固定されるのが一般的である。

ところで、通常、床暖房システムは秋期ないし冬期以外に使用されない。この床暖房の使用時には、暖房床パネルの表面温度が３０〜３５℃程度に、また床下温度が４０〜４５℃程度にそれぞれ加熱されるため、表面の暖房床パネルだけでなく床下地材の乾燥が進む。その後、春になって床暖房の使用を停止した後に梅雨の時期を迎えると、暖房床パネル及び床下地材が吸湿して湿気により伸びることとなる。 By the way, normally, the floor heating system is not used except in the fall or winter. When this floor heating is used, since the surface temperature of the heating floor panel is heated to about 30 to 35 ° C. and the temperature under the floor is about 40 to 45 ° C., not only the surface heating floor panel but also the floor base material is dried. Advances. After that, when the rainy season is reached after stopping the use of floor heating in spring, the heating floor panel and the floor base material absorb moisture and extend due to moisture.

その場合、外殻部材内に設けられた空洞部が大きい上に、表面から吸った湿気による薄い表面部（空洞部の底面部）の吸湿による伸び代が、床下地材の吸湿による伸び代より大きくなる。そのため、暖房床パネルの枠部間で表面部が太鼓状（中凸状）に膨れ、長期間の使用によって顕著になるという問題があった。 In that case, the hollow portion provided in the outer shell member is large, and the elongation allowance due to moisture absorption of the thin surface portion (bottom surface portion of the cavity portion) due to moisture absorbed from the surface is larger than the elongation allowance due to moisture absorption of the floor base material. growing. For this reason, there is a problem that the surface portion swells in a drum shape (medium convex shape) between the frame portions of the heating floor panel, and becomes prominent by long-term use.

本発明は斯かる点に鑑みてなされたもので、その目的は、暖房床パネルの外殻部材の構造に工夫を加えることで、その表面側が膨出するのを抑制し、長期間に亘って安定して美麗な外観を呈し得るようにすることにある。 The present invention has been made in view of such a point, and the object thereof is to devise the structure of the outer shell member of the heating floor panel, thereby suppressing the bulging of the surface side, and for a long period of time. The object is to provide a stable and beautiful appearance.

上記の目的の達成のため、この発明では、外殻部材の裏面の空洞部の内底面（表面部の裏面）と外殻部材の裏面に接着されるバッカー材との間にブロック材を掛け渡し、このブロック材により、外殻部材の表面部が表面側に膨出変形するするのを規制するようにした。 In order to achieve the above object, according to the present invention, a block material is bridged between the inner bottom surface of the hollow portion on the back surface of the outer shell member (the back surface of the front surface portion) and the backer material bonded to the back surface of the outer shell member. The block member restricts the surface portion of the outer shell member from bulging and deforming to the surface side.

具体的には、請求項１の発明に係る暖房床パネルは、表面に化粧加工が施されている一方、裏面に、周辺部を残して凹陥させてなる空洞部が形成され、四周側面に実加工が施されている外殻部材と、この外殻部材の空洞部内に格納される埋込パネル部材と、上記外殻部材の裏面に上記空洞部を閉じるように設けられたバッカー材とを備えている。 Specifically, the heating floor panel according to the invention of claim 1 is provided with a decorative process on the front surface, and on the back surface is formed with a hollow portion that is recessed to leave the peripheral portion. An outer shell member that has been processed; an embedded panel member that is housed in the cavity of the outer shell member; and a backer material that is provided on the back surface of the outer shell member so as to close the cavity. ing.

そして、上記空洞部の内底面には少なくとも１つのブロック材が先端面を外殻部材の周辺部裏面と面一状にして突設されている。 Then, at least one block member projects from the inner bottom surface of the hollow portion so that the front end surface is flush with the rear surface of the peripheral portion of the outer shell member.

また、上記埋込パネル部材は、上記空洞部内に表面を空洞部の底部側に位置付けて配置されかつ上記ブロック材が挿通される挿通口が抜き加工された熱伝導性板状体からなる均熱板と、この均熱板の裏面側に配置され、所定の配線形状に形成されたヒータ線、及び該ヒータ線に結合されたサーモスタットと、上記空洞部内の開口側に配置され、少なくとも上記ブロック材が挿通される挿通口が抜き加工された断熱材とからなる。 In addition, the embedded panel member is arranged so that the surface thereof is positioned in the cavity portion at the bottom side of the cavity portion, and the soaking is made of a thermally conductive plate-like body in which the insertion port through which the block material is inserted is punched. A plate, a heater wire disposed on the back surface side of the soaking plate, formed in a predetermined wiring shape, a thermostat coupled to the heater wire, and disposed on the opening side in the cavity, at least the block material It consists of the heat insulating material by which the insertion port through which is inserted is punched.

さらに、上記バッカー材は、上記外殻部材の周辺部裏面及びブロック材の先端面と一体的に接着されている。 Further, the backer material is integrally bonded to the back surface of the peripheral portion of the outer shell member and the front end surface of the block material.

また、請求項２の発明では、表面に型押し成形により所定の配線形状にヒータ線収納溝が形成され、かつサーモスタット用挿通部及びブロック材用の挿通口が抜き加工された鉱物質繊維板状体からなる断熱材と、この断熱材のヒータ線収納溝の配線形状に合致する形状に予め形成され、該ヒータ線収納溝に収納されたヒータ線と、該ヒータ線に接合され、上記サーモスタット用挿通部に収容されたサーモスタットと、上記断熱材のヒータ線収納溝側に上記ヒータ線及びサーモスタットと接して設けられ、ブロック材用の挿通口が打ち抜き加工された熱伝導性板状体からなる均熱板とを備えた埋込パネル部材を設ける。 Further, in the invention of claim 2, a mineral fiber plate shape in which a heater wire storage groove is formed in a predetermined wiring shape by stamping on the surface, and a thermostat insertion portion and a block material insertion port are punched out. A heat insulating material made of a body and a shape that matches the wiring shape of the heater wire housing groove of the heat insulating material, and the heater wire housed in the heater wire housing groove and joined to the heater wire, for the thermostat A thermostat housed in the insertion portion, and a heat conductive plate-like body that is provided in contact with the heater wire and the thermostat on the heater wire housing groove side of the heat insulating material, and in which the insertion port for the block material is punched. An embedded panel member provided with a hot plate is provided.

また、表面に化粧加工が施されている一方、裏面に、周辺部を残して凹陥させてなる空洞部が形成され、該空洞部の内底面にブロック材が先端面を周辺部の裏面と面一状にして突設され、上記空洞部内に上記埋込パネル部材が均熱板を表面側に向けて組み込まれた外殻部材と、この外殻部材の裏面側に上記空洞部を閉じるように設けられたバッカー材とを備え、このバッカー材は、上記外殻部材の周辺部裏面及びブロック材の先端面と一体的に接着されている。 In addition, while the surface is decorated, the back surface is formed with a hollow portion that is recessed to leave the peripheral portion, and the block material faces the tip surface on the inner bottom surface of the hollow portion and the back surface of the peripheral portion. The outer shell member is provided in a projecting manner and the embedded panel member is incorporated in the cavity portion with the heat equalizing plate facing the front surface side, and the cavity portion is closed on the back surface side of the outer shell member. The backer material is provided, and this backer material is integrally bonded to the peripheral portion back surface of the outer shell member and the front end surface of the block material.

これら発明の構成によると、外殻部材の裏面に周辺部を残して凹陥状の空洞部が形成され、この空洞部内に埋込パネル部材が格納される。空洞部は外殻部材の周辺部裏面に接着したバッカー材により閉鎖される。そして、空洞部内の底面にブロック材が突設され、このブロック材は埋込パネル部材における断熱材及び均熱板の挿通口を挿通され、その先端面が外殻部材裏面に接着したバッカー材に一体的に接着されているので、外殻部材において周辺部以外の中間部に位置する表面部はブロック材を介してバッカー材に連結されることになる。このことで、外殻部材の表面部がバッカー材によって補強され、バッカー材を床下地材に接着するときには床下地材によっても補強され、その表面部が吸湿による伸長差によって表面側に膨出変形するのを確実に防止することができる。 According to the configuration of these inventions, a recessed hollow portion is formed on the back surface of the outer shell member, leaving a peripheral portion, and the embedded panel member is stored in the hollow portion. The hollow portion is closed by a backer material bonded to the back surface of the peripheral portion of the outer shell member. Then, a block material projects from the bottom surface in the cavity, and this block material is inserted into the heat insulating material in the embedded panel member and the insertion port of the heat equalizing plate, and the tip surface of the back material is bonded to the back surface of the outer shell member. Since they are bonded together, the surface portion of the outer shell member located at the intermediate portion other than the peripheral portion is connected to the backer material via the block material. As a result, the surface part of the outer shell member is reinforced by the backer material, and when the backer material is bonded to the floor base material, it is also reinforced by the floor base material. Can be surely prevented.

請求項３の発明では、バッカー材の少なくともブロック材に対応した部分に、該ブロック材の先端面よりも小さい貫通孔が抜き加工され、ブロック材の先端面は上記貫通孔を除いた部分でバッカー材に接着されている。 In the invention of claim 3, a through hole smaller than the front end surface of the block material is punched in a portion corresponding to at least the block material of the back material, and the front end surface of the block material is backed by the portion excluding the through hole. Bonded to the material.

この構成によると、暖房床パネルの施工時にバッカー材を床下地材に接着するとき、ブロック材をもバッカー材の貫通孔を介して床下地材に直接に接着することができ、外殻部材において周辺部以外の中間部に位置する表面部をブロック材及びバッカー材を介して床下地材に連結して、外殻部材の表面部が表面側に膨出変形するのをより一層確実に防止することができる。 According to this configuration, when the backer material is bonded to the floor base material during the construction of the heating floor panel, the block material can also be directly bonded to the floor base material through the through hole of the backer material. By connecting the surface portion located in the intermediate portion other than the peripheral portion to the floor base material via the block material and the backer material, the surface portion of the outer shell member is further prevented from bulging and deforming to the surface side. be able to.

以上説明したように、請求項１又は２の発明によると、外殻部材の裏面に空洞部を凹陥形成して、その空洞部に埋込パネル部材を格納し、外殻部材の裏面周縁部にバッカー材を接着して空洞部を封閉する暖房床パネルにおいて、空洞部の内底面とバッカー材との間に亘り各々に接着されるブロックを架設したことにより、外殻部材の表面部をバッカー材によって補強して、その表面部が吸湿による伸長差によって表面側に膨出変形するのを確実に防止でき、暖房床パネルの外観を長期間に亘って安定して保持することができる。 As described above, according to the first or second aspect of the present invention, the hollow portion is formed in the back surface of the outer shell member, the embedded panel member is stored in the hollow portion, and the rear surface peripheral portion of the outer shell member is stored. In the heated floor panel that seals the cavity by adhering the backer material, the surface part of the outer shell member is backered by laying blocks to be bonded between the inner bottom surface of the cavity and the backer material. Thus, the surface portion can be reliably prevented from bulging and deforming to the surface side due to a difference in elongation due to moisture absorption, and the appearance of the heating floor panel can be stably maintained for a long period of time.

請求項３の発明によると、バッカー材の少なくともブロック材に対応した部分に、ブロック材の先端面よりも小さい貫通孔を形成し、ブロック材の先端面を貫通孔を除いた部分でバッカー材に接着したことにより、ブロック材をもバッカー材の貫通孔を介して床下地材に直接に接着でき、外殻部材の表面部が表面側に膨出変形するのをより一層確実に防止することができる。 According to the invention of claim 3, a through-hole smaller than the front end surface of the block material is formed in at least a portion of the backer material corresponding to the block material, and the back surface of the block material is removed from the back hole by the portion excluding the through-hole By adhering, the block material can also be directly bonded to the floor base material through the through-hole of the backer material, and the surface portion of the outer shell member can be prevented more reliably from bulging and deforming to the surface side. it can.

以下、本発明の最良の実施形態を図面に基づいて詳細に説明する。以下の好ましい実施形態の説明は、本質的に例示に過ぎず、本発明、その適用物或いはその用途を制限することを意図するものでは全くない。 Hereinafter, the best embodiment of the present invention will be described in detail with reference to the drawings. The following description of the preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its application, or its application.

（実施形態１）
図１及び図２は本発明の実施形態に係る暖房床パネルＡを示し、この暖房床パネルＡは、住宅等の床面に施工される電気式のもので、外殻部材１、ブロック材８、埋込パネル部材１５及びバッカー材２６を備えている。 (Embodiment 1)
1 and 2 show a heated floor panel A according to an embodiment of the present invention. The heated floor panel A is an electric type constructed on a floor surface of a house or the like, and includes an outer shell member 1 and a block material 8. The embedded panel member 15 and the backer material 26 are provided.

（1）外殻部材
図３及び図４に示すように、上記外殻部材１は、平面視で一辺側が長尺となる矩形状のもので、表面側となる床面材としての矩形状の表面部２（表面材）と、この表面部２の裏面に四辺を囲むように固着された枠部３（枠材）とからなる。外殻部材１の裏面には、枠部３に囲まれた凹陥状の空洞部１０が形成され、この空洞部１０の深さは上記埋込パネル部材１５の高さと同じかそれよりも若干大きい寸法に設定されている。表面部２には、剛性のある木質材料等の板状物が使用される。また、枠部３としても、表面部２と同様の材質の剛性材が使用される。 (1) Outer shell member As shown in FIGS. 3 and 4, the outer shell member 1 is a rectangular shape whose one side is long in plan view, and has a rectangular shape as a flooring material on the surface side. It consists of a surface portion 2 (surface material) and a frame portion 3 (frame material) fixed to the back surface of the surface portion 2 so as to surround four sides. A concave cavity 10 surrounded by the frame 3 is formed on the back surface of the outer shell member 1, and the depth of the cavity 10 is equal to or slightly larger than the height of the embedded panel member 15. Set to dimensions. A plate-like object such as a rigid wood material is used for the surface portion 2. Further, a rigid material made of the same material as that of the surface portion 2 is used as the frame portion 3.

一方、上記のように表面部２に枠部３を固着する固着構造に代え、枠部３と同じ厚さを有する板材（基材）の裏面を切削加工することで、空洞部１０を凹陥形成することもできる。その場合、表面部２と枠部３とが一体化された一体構造となる。具体的には、例えば厚さ１２ｍｍの暖房床パネルＡを作製するために、前者の固着構造では、例えば厚さ６ｍｍの表面部２の裏面に６ｍｍの厚さを持つ枠部３を接着して外殻部材１が形成される。一方、後者の一体構造では、厚さ１２ｍｍの板材の裏面側に所定深さの空洞部１０を切削加工して外殻部材１が形成される。本発明では、いずれにも限定されないが、後者の一体構造の方が効率的である。 On the other hand, instead of the fixing structure for fixing the frame portion 3 to the front surface portion 2 as described above, the cavity portion 10 is formed as a recess by cutting the back surface of the plate material (base material) having the same thickness as the frame portion 3. You can also In that case, it becomes an integrated structure in which the surface portion 2 and the frame portion 3 are integrated. Specifically, in order to produce the heating floor panel A having a thickness of 12 mm, for example, in the former fixing structure, the frame portion 3 having a thickness of 6 mm is bonded to the back surface of the surface portion 2 having a thickness of 6 mm, for example. The outer shell member 1 is formed. On the other hand, in the latter integrated structure, the outer shell member 1 is formed by cutting the cavity portion 10 having a predetermined depth on the back surface side of a plate material having a thickness of 12 mm. In the present invention, although not limited to any one, the latter integrated structure is more efficient.

外殻部材１の表面（表面部２の上面）には、例えば表面仕上げ材１２が張り付けられて化粧加工が施されている。この表面仕上げ材１２に代え、表面部２の上面に、木質化粧板やクッションフロア、カーペット等の化粧板を一体に接着することで、化粧加工を施すようにしてもよい。 On the surface of the outer shell member 1 (the upper surface of the surface portion 2), for example, a surface finishing material 12 is attached and subjected to a decorative process. Instead of the surface finish 12, a decorative process may be performed by integrally bonding a decorative board such as a wooden decorative board, a cushion floor, or a carpet to the upper surface of the surface portion 2.

また、外殻部材１の四周側面（枠部３の外側面）には実加工が施されている。具体的には、外殻部材１の幅方向に対向する側面の一方には、厚さ方向の中間部を長さ方向に沿って溝状に切削することで雌実部４が形成され、他方には表裏面の隅角部をそれぞれ矩形状に切り欠くことで雄実部５が形成されている。また、外殻部材１の長さ方向に対向する側面の一方には上記と同様の雌実部６が、また他方には同様の雄実部７がそれぞれ形成されており、複数枚の暖房床パネルＡ，Ａ，…を幅方向及び長さ方向に並べたときに、隣接する１対の暖房床パネルＡ，Ａの一方の外殻部材１の雌実部４，６に他方の暖房床パネルＡの外殻部材１の雄実部５，７が嵌合されて施工されるようになっている。 Further, actual processing is applied to the four circumferential side surfaces of the outer shell member 1 (the outer surface of the frame portion 3). Specifically, a female real part 4 is formed on one of the side surfaces facing the width direction of the outer shell member 1 by cutting an intermediate part in the thickness direction into a groove shape along the length direction, The male and female parts 5 are formed by cutting out the corners of the front and back surfaces in a rectangular shape. Further, a female real part 6 similar to the above is formed on one of the side surfaces facing the length direction of the outer shell member 1, and a similar male real part 7 is formed on the other side, and a plurality of heating floors are formed. When the panels A, A,... Are arranged in the width direction and the length direction, the other heating floor panel is connected to the female real parts 4, 6 of one outer shell member 1 of a pair of adjacent heating floor panels A, A. The male parts 5 and 7 of the outer shell member 1 of A are fitted and constructed.

（2）ブロック材
図３及び図４に示すように、上記外殻部材１における空洞部１０内の底面には、周囲の枠部３から離れた位置に、上下方向に延びる複数の例えば断面長方形状の角材からなるブロック材８，８，…が接着されて一体的に突設されている。この各ブロック材８の高さは空洞部１０の深さと同じであり、ブロック材８の先端面は外殻部材１の周辺部裏面と面一状にして位置している。 (2) Block material As shown in FIGS. 3 and 4, the bottom surface in the cavity 10 of the outer shell member 1 has a plurality of, for example, cross-sectional rectangles extending in the vertical direction at positions away from the surrounding frame 3. Block members 8, 8,... Made of square-shaped square members are bonded and protruded integrally. The height of each block member 8 is the same as the depth of the cavity 10, and the front end surface of the block member 8 is positioned flush with the rear surface of the peripheral portion of the outer shell member 1.

尚、この各ブロック材８については、上記のように外殻部材１の裏面を切削加工して空洞部１０を凹陥形成するとき、一部を残すように切削することによって、その残した部分をブロック材８としてもよい。すなわち、表面部２と枠部３とブロック材８とが一体化された一体構造となる。こうすると、生産性もよく、強度的にも安心で、外殻部材１の周辺部との面一性を確保し易いために好ましい。 In addition, about each block material 8, when the back surface of the outer shell member 1 is cut as described above to form the hollow portion 10 to be recessed, the remaining portion is cut by cutting so as to leave a part. The block material 8 may be used. That is, an integrated structure in which the surface portion 2, the frame portion 3, and the block material 8 are integrated. This is preferable because the productivity is good, the strength is safe, and it is easy to ensure the flushness with the peripheral portion of the outer shell member 1.

複数のブロック材８，８，…は、外殻部材１の長さ方向及び幅方向にそれぞれ所定の間隔をあけて配置されている。すなわち、例えば図３に示すように、外殻部材１の長さ方向両端部にはそれぞれ１対のブロック材８，８，…が各々の断面の長辺方向を外殻部材１の幅方向と平行にしかつ該外殻部材１の幅方向に直列に並んで配置され、外殻部材１の長さ方向中間部には３つのブロック材８，８，…が各々の長辺方向を外殻部材１の長さ方向と平行にしかつ該外殻部材１の長さ方向に対し斜めになるように並んで配置されている。 The plurality of block members 8, 8,... Are arranged at predetermined intervals in the length direction and the width direction of the outer shell member 1, respectively. That is, for example, as shown in FIG. 3, a pair of block members 8,... Are respectively provided at both ends in the length direction of the outer shell member 1 so that the long side direction of each cross section is the width direction of the outer shell member 1. Are arranged in parallel and in series in the width direction of the outer shell member 1, and three block members 8, 8,... 1 are arranged side by side so as to be parallel to the length direction of 1 and oblique to the length direction of the outer shell member 1.

このとき、ブロック材８の大きさが大きくなり過ぎると、表面の均熱効果を阻害する。その断面の短辺方向の大きさを「幅」とし、長辺方向の大きさを「長さ」とした場合、幅は１０ｍｍ〜３０ｍｍ程度に限定され、好適には１０ｍｍ〜１５ｍｍ程度の幅が用いられる。１０ｍｍよりも薄い場合は、強度的に不足する一方、３０ｍｍを超えると、均熱効果的に不適当であるからである。 At this time, if the size of the block material 8 becomes excessively large, the soaking effect on the surface is hindered. When the size in the short side direction of the cross section is “width” and the size in the long side direction is “length”, the width is limited to about 10 mm to 30 mm, and preferably about 10 mm to 15 mm. Used. When the thickness is less than 10 mm, the strength is insufficient. On the other hand, when the thickness exceeds 30 mm, the soaking effect is inappropriate.

一方、長さについては、短すぎる場合は、暖房床パネルＡの施工時にバッカー材２６の裏面（下面）に接着剤を線状に塗布するが、この場合に接着剤塗布位置とブロック材８の位置とがずれる場合が考えられるため、２０ｍｍ以下は好ましくない。上記図３に示す例では、外殻部材１の長さ方向両端部に位置する４つ（２対）のブロック材８，８，…の各々の幅は１２ｍｍ、長さは３５ｍｍである。長さ方向中央に位置する１つのブロック材８の幅は１２ｍｍ、長さは９５ｍｍであり、長さ方向中央及び端部間に位置する２つのブロック材８，８の各々の幅は１２ｍｍ、長さは５５ｍｍである。 On the other hand, if the length is too short, the adhesive is applied linearly to the back surface (lower surface) of the backer material 26 during the construction of the heating floor panel A. In this case, the adhesive application position and the block material 8 Since the position may be displaced, 20 mm or less is not preferable. In the example shown in FIG. 3, the width of each of the four (two pairs) block members 8, 8,... Located at both ends in the length direction of the outer shell member 1 is 12 mm and the length is 35 mm. The width of one block member 8 located at the center in the length direction is 12 mm and the length is 95 mm, and the width of each of the two block members 8 and 8 located between the center and the end in the length direction is 12 mm and long. The height is 55 mm.

また、大きな断面積の細長いブロック材８，８，…を配置するよりも、小さな断面積のブロック材８，８，…を分散させて配置した方が表面部２（外殻部材１の表面部）の膨れ防止効果は大きい。表面部２の膨れを抑えつつ、均熱効果を損なわないようにするためには、一般的な３００×１９００ｍｍ程度の暖房床パネルＡの場合、幅１０〜１５ｍｍでかつ長さ３０〜１００ｍｍ程度のブロック材８を６〜１０個程度、均等に配置するのが好ましい。 In addition, it is more preferable to disperse and arrange the block members 8, 8,... Having a small cross-sectional area than the elongated block members 8, 8,. ) Is very effective in preventing swelling. In order to suppress the swelling of the surface portion 2 and not to impair the soaking effect, in the case of a general heating floor panel A of about 300 × 1900 mm, the width is about 10 to 15 mm and the length is about 30 to 100 mm. It is preferable that about 6 to 10 block members 8 are arranged uniformly.

このブロック材８の配置は上記図３に示す配列に限定されず、適宜のレイアウトを採用することができる。例えば図７は、３対のブロック材８，８，…を、各対のブロック材８，８が外殻部材１の幅方向に対向しかつ各ブロック材８の「長さ方向」が外殻部材１の長さ方向に沿うように等間隔をあけて配列したものである。各ブロック材８は幅１２ｍｍ、長さ５５ｍｍの同じものである。 The arrangement of the block members 8 is not limited to the arrangement shown in FIG. 3, and an appropriate layout can be adopted. For example, FIG. 7 shows three pairs of block members 8, 8,..., Each pair of block members 8, 8 faces the width direction of the outer shell member 1, and the “length direction” of each block member 8 is the outer shell. The members 1 are arranged at equal intervals along the length direction of the members 1. Each block member 8 has the same width of 12 mm and a length of 55 mm.

また、図８は、５対のブロック材８，８，…を、各対のブロック材８，８が外殻部材１の幅方向に対向しかつ各ブロック材８の「長さ方向」が外殻部材１の長さ方向に沿うように等間隔をあけて配列したものである。各ブロック材８は幅１２ｍｍ、長さ３５ｍｍの同じものである。 FIG. 8 shows five pairs of block members 8, 8,..., Each pair of block members 8, 8 facing the width direction of the outer shell member 1, and the “length direction” of each block member 8 is outside. The shell members 1 are arranged at equal intervals along the length direction. Each block member 8 has the same width of 12 mm and a length of 35 mm.

埋込パネル部材１５は、上記外殻部材１の凹陥状の空洞部１０内にその略全体に亘り格納されて組み込まれて使用される。図５に示すように、この埋込パネル部材１５は、平面視で一辺側が長尺な矩形状を呈する断熱材１６と、この断熱材１６の上面側に配置され、予め配線形状に加工されているヒータ線１８、サーモスタット２１より導出される導出線１９及び送り線２０と、これら各線１８〜２０の上部側に設けられた均熱板２３とで構成されている。上記送り線２０は、隣り合う暖房床パネルＡ，Ａ間における埋込パネル部材１５のヒータ線１８同士を電気的に接続するのに用いられる。 (3) Embedded Panel Member The embedded panel member 15 is stored and incorporated in the recessed hollow portion 10 of the outer shell member 1 over almost the whole. As shown in FIG. 5, the embedded panel member 15 is arranged on the heat insulating material 16 having a long rectangular shape on one side in a plan view, and on the upper surface side of the heat insulating material 16 and processed into a wiring shape in advance. Heater wire 18, lead wire 19 and feed wire 20 derived from thermostat 21, and heat equalizing plate 23 provided on the upper side of each wire 18 to 20. The feed line 20 is used to electrically connect the heater wires 18 of the embedded panel member 15 between the adjacent heating floor panels A and A.

上記断熱材１６は硬質ウレタン、或いはロックウール板等の鉱物質繊維板状体等の硬質板状断熱材が好適に使用される。ブロック材８を設けているため、他の軟質断熱材を使用することも可能であるが、歩行時の撓みが大きくなる理由で好ましくない。また、その場合に、ブロック材８の配置数を増やしてもよいが、表面部２に対する均熱効果が阻害されるため、あまり好ましくない。つまり、硬質板状の断熱材１６と適宜配置された複数のブロック材８，８，…との効果により、歩行感に優れた暖房床パネルＡが得られる。 As the heat insulating material 16, a hard plate-like heat insulating material such as hard urethane or a mineral fiber plate such as rock wool plate is preferably used. Since the block material 8 is provided, it is possible to use another soft heat insulating material, but this is not preferable because the bending during walking increases. In this case, the number of the block members 8 may be increased, but this is not preferable because the soaking effect on the surface portion 2 is hindered. That is, the heating floor panel A excellent in walking feeling can be obtained by the effect of the hard plate-like heat insulating material 16 and the plurality of block members 8, 8,.

具体的には、断熱材１６として、例えば澱粉等の水溶性バインダを用いたロックウール板（厚さが約７ｍｍで、比重０．３〜０．５程度）を断熱材として用いるが、その芯層が表裏層よりも比重の高い材料からなる多層構成にすることもできる。具体的には、表裏層が鉱物質繊維と無機質粉体とを主原料とした高密度層にし、芯層がシラス発泡体のような軽量無機質発泡体が主原料の軽量層にする等であり、この場合は、全体比重が０．５〜１．０程度であっても、芯層が座屈し易いので細かい溝を形成する場合にも適用できるのである。 Specifically, for example, a rock wool plate (thickness of about 7 mm and specific gravity of about 0.3 to 0.5) using a water-soluble binder such as starch is used as the heat insulating material 16. A multi-layer structure in which a layer is made of a material having a specific gravity higher than that of the front and back layers can also be used. Specifically, the front and back layers are high-density layers made mainly of mineral fibers and inorganic powder, and the core layer is a light-weight inorganic foam such as shirasu foam, which is a light-weight layer of the main raw material. In this case, even if the total specific gravity is about 0.5 to 1.0, the core layer is likely to buckle, so that it can be applied to the case where fine grooves are formed.

上記鉱物質繊維板状体からなる断熱材１６の表面には、型押し成形により所定の配線形状にヒータ線収納溝１６ａ、導出線収納溝１６ｂ及び送り線収納溝１６ｃが形成されている。また、断熱材１６には、サーモスタット用挿通部１６ｄ及びブロック材用挿通口１６ｅが抜き加工されている。 A heater wire storage groove 16a, a lead wire storage groove 16b, and a feed line storage groove 16c are formed in a predetermined wiring shape by stamping on the surface of the heat insulating material 16 made of the mineral fiber plate. Further, the heat insulating material 16 is punched with a thermostat insertion portion 16d and a block material insertion port 16e.

上記ヒータ線１８は、上記断熱材１６のヒータ線収納溝１６ａに収納されるワイヤー状のもので、予め上記断熱材１６のヒータ線収納溝１６ａの配線形状に合致する形状に形成されている。このヒータ線１８は、特に限定されるものではないが、ワイヤヒータをガラス繊維やケプラー繊維で補強した線径が０．２ｍｍ〜１．５ｍｍ程度の導線１８ａを熱可塑性樹脂の外被１８ｂで被覆して外径を２．０ｍｍ〜４．０ｍｍにしたものが用いられる。また、導出線１９及び送り線２０も、ヒータ線１８と同様に導線１９ａ，２０ａを熱可塑性樹脂の外被１９ｂ，２０ｂで被覆してなるものが用いられる。ヒータ線１８は、サーモスタット２１と接続された状態で熱融着により均熱板２３に固定されている。 The heater wire 18 is wire-like that is housed in the heater wire housing groove 16a of the heat insulating material 16, and is previously formed in a shape that matches the wiring shape of the heater wire housing groove 16a of the heat insulating material 16. The heater wire 18 is not particularly limited, but a wire 18a having a wire diameter reinforced by glass fiber or Kepler fiber and having a wire diameter of about 0.2 mm to 1.5 mm is covered with a jacket 18b of a thermoplastic resin. The outer diameter is 2.0 mm to 4.0 mm. Similarly to the heater wire 18, the lead wire 19 and the feed wire 20 are formed by covering the conductive wires 19a and 20a with the outer sheaths 19b and 20b of thermoplastic resin. The heater wire 18 is fixed to the heat equalizing plate 23 by thermal fusion while being connected to the thermostat 21.

サーモスタット２１は上記断熱材１６と略同じ厚さであり、上記ヒータ線１８と接続される。また、このサーモスタット２１は上記断熱材１６のサーモスタット用挿通部１６ｄに収容される。上記サーモスタット２１は、断熱材１６よりも薄ければよく、薄い場合は断熱材１６のサーモスタット用挿通部１６ｄの代わりに、サーモスタット２１の形状に対応したサーモスタット収納穴（図示せず）を、ヒータ線収納溝１６ａ等と同様に型押し成形により設けてもよい。 The thermostat 21 has substantially the same thickness as the heat insulating material 16 and is connected to the heater wire 18. The thermostat 21 is accommodated in the thermostat insertion portion 16 d of the heat insulating material 16. The thermostat 21 only needs to be thinner than the heat insulating material 16, and if it is thin, instead of the thermostat insertion portion 16d of the heat insulating material 16, a thermostat housing hole (not shown) corresponding to the shape of the thermostat 21 is provided as a heater wire. Similar to the storage groove 16a and the like, it may be provided by stamping.

均熱板２３は熱伝導性板状体からなり、例えば０．２〜０．５ｍｍ程度の熱伝導性に優れたアルミニウム、ステンレス等の金属板が好ましい。この均熱板２３は、上記断熱材１６のヒータ線収納溝１６ａ側に上記ヒータ線１８及びサーモスタット２１と接して設けられている。この均熱板２３には、少なくともブロック材用挿通口２３ａが打ち抜き加工されている。 The soaking plate 23 is made of a thermally conductive plate, and is preferably a metal plate such as aluminum or stainless steel having excellent thermal conductivity of about 0.2 to 0.5 mm. The soaking plate 23 is provided on the heater wire housing groove 16 a side of the heat insulating material 16 so as to be in contact with the heater wire 18 and the thermostat 21. In the heat equalizing plate 23, at least a block material insertion port 23a is punched.

（4）バッカー材
上記バッカー材２６は合板、厚紙、クラフト紙、合成樹脂板、布、不織布、ガラスクロスシート等、或いはそれらの２つ以上を組み合わせた複合板等が用いられる。このバッカー材２６は、上記外殻部材１の表面部２と略同じ大きさ及び形状のもので、外周面が外殻部材１の枠部３外側面と面一になるように、その周辺部裏面及びブロック材８の先端面と一体的に接着されている。すなわち、図１に示すように、上記外殻部材１の空洞部１０内に裏側から埋込パネル部材１５が組み込まれた状態で、その空洞部１０の裏側の開口部がバッカー材２６としての下面材２４により封蓋されることで、暖房床パネルＡが形成される。 (4) Backer material The backer material 26 is made of plywood, cardboard, kraft paper, synthetic resin plate, cloth, non-woven fabric, glass cloth sheet, or a composite plate in which two or more thereof are combined. The backer material 26 has substantially the same size and shape as the surface portion 2 of the outer shell member 1, and its peripheral portion so that the outer peripheral surface is flush with the outer surface of the frame portion 3 of the outer shell member 1. The back surface and the front end surface of the block material 8 are integrally bonded. That is, as shown in FIG. 1, in the state where the embedded panel member 15 is incorporated into the cavity portion 10 of the outer shell member 1 from the back side, the opening on the back side of the cavity portion 10 is the lower surface as the backer material 26. By being sealed with the material 24, the heating floor panel A is formed.

このバッカー材２６の裏面（床下地材Ｂと接する下面）には、施工時にブロック材８の位置が判るような目印が予め印刷等により設けられているのが好ましい。 On the back surface of the backer material 26 (the lower surface in contact with the floor base material B), it is preferable that a mark that allows the position of the block material 8 to be known at the time of construction is provided in advance by printing or the like.

以上の構成の暖房床パネルＡを、施工する部屋の敷設面積に応じて縦横に並べて組み合わせることで、暖房床Ａを構成するようにしている。 The heating floor A is configured by combining the heating floor panel A having the above configuration in a row and a row according to the laying area of the room to be constructed.

（5）暖房床パネルの製造方法
上記断熱材１６をロックウール板等の鉱物質繊維板状体とした場合の暖房床パネルＡの製造方法の一例を図６により説明する。まず、断熱材１６の上面（表面）に水を塗布する。この水の塗布はスポンジロール等で行われるが、過剰に塗布すると水分蒸発に時間がかかるため、その塗布量は断熱材１６の上面全域で４〜８ｇ／尺^２に設定される。尚、水の塗布は、後述するヒータ線収納溝１６ａ、導出線収納溝１６ｂ及び送り線収納溝１６ｃにそれぞれ対応する部分のみ行うようにしてもよい。また、塗布する水の中に、撥水剤やメラミン等の熱硬化性樹脂を混入させてもよく、その場合には、水分の蒸発に伴い断熱材１６上面の耐水性が向上し、その後の寸法変化がより効果的に防止できるとともに、上面の硬度が高くなって荷重に対する耐性が向上する。この工程は、良好なヒータ線収納溝１６ａ、導出線収納溝１６ｂ及び送り線収納溝１６ｃを形成する上で好適であるが、特に必要とするものではない。 (5) Manufacturing method of heating floor panel An example of a manufacturing method of the heating floor panel A when the heat insulating material 16 is a mineral fiber plate such as a rock wool board will be described with reference to FIG. First, water is applied to the upper surface (surface) of the heat insulating material 16. The application of water is performed by a sponge roll or the like, but if it is applied excessively, it takes time to evaporate the water. Therefore, the application amount is set to ⁴ to 8 g / scale ² over the entire upper surface of the heat insulating material 16. The application of water may be performed only on portions corresponding to heater wire storage grooves 16a, lead wire storage grooves 16b, and feed line storage grooves 16c, which will be described later. In addition, a thermosetting resin such as a water repellent or melamine may be mixed in the water to be applied. In that case, the water resistance of the upper surface of the heat insulating material 16 is improved as the moisture evaporates, and thereafter The dimensional change can be prevented more effectively, and the hardness of the upper surface is increased to improve the load resistance. This step is suitable for forming the good heater wire storage groove 16a, lead-out wire storage groove 16b, and feed wire storage groove 16c, but is not particularly required.

その後、図示しないが、上記断熱材１６をホットプレスに搬入する。このホットプレスは下側金型と型板としての上側金型とを有し、その上側金型の下面には、ヒータ線１８、導出線１９及び送り線２０の配線形状（図５参照）にそれぞれ倣って突出するヒータ線用、導出線用及び送り線用の各凸部（成形面）が形成されている。そして、そのホットプレスの下側金型上に上記断熱材１６を下面が下側となるよう載置した後、その断熱材１６の上面側から上側金型を当てて加熱加圧することにより、断熱材１６の上面側にヒータ線収納溝１６ａ、導出線収納溝１６ｂ及び送り線収納溝１６ｃを刻設する。このとき、ホットプレスの加熱加圧は、上側金型を予め２００°Ｃ〜３００°Ｃに加熱しておき、２〜４ｋｇ／ｃｍ^２の圧力で行う。 Then, although not shown in figure, the said heat insulating material 16 is carried in to a hot press. This hot press has a lower mold and an upper mold as a mold plate. On the lower surface of the upper mold, the wiring shape of the heater wire 18, the lead-out wire 19 and the feed wire 20 (see FIG. 5) is provided. Protrusions (molding surfaces) for the heater wire, the lead-out wire, and the feed wire that project in accordance with each other are formed. And after mounting the said heat insulating material 16 on the lower metal mold | die of the hot press so that a lower surface may become a lower side, it heat-presses by applying an upper metal mold | die from the upper surface side of the heat insulating material 16, and heat-pressing. A heater wire storage groove 16a, a lead-out wire storage groove 16b, and a feed line storage groove 16c are formed on the upper surface side of the material 16. At this time, the heating and pressurization of the hot press is performed at a pressure of ^{2 to 4} kg / cm ² by heating the upper die to 200 ° C. to 300 ° C. in advance.

この場合、型押し成形性及び型押し成形後の戻り（スプリングバック）の少なさに優れた鉱物質繊維製板状体により断熱材１６が構成されているので、この断熱材１６の上面側に型押し成形によってヒータ線収納溝１６ａ、導出線収納溝１６ｂ及び送り線収納溝１６ｃを所定の配線形状に確実かつ容易に形成することができる。 In this case, since the heat insulating material 16 is composed of the mineral fiber plate-like body excellent in the moldability and the small amount of return (springback) after the mold forming, on the upper surface side of the heat insulating material 16. The heater wire housing groove 16a, the lead-out wire housing groove 16b, and the feed wire housing groove 16c can be reliably and easily formed into a predetermined wiring shape by stamping.

しかる後、ヒータ線１８の蛇行区間に対応する断熱材１６の所望位置にサーモスタット用挿通部１６ｄ及びブロック材用挿通口１６ｅを打ち抜き加工する。このサーモスタット用挿通部１６ｄの打ち抜き加工は、温度ヒューズを備えたサーモスタット２１（図５に表れる）の高さが断熱材１６の厚さと略同じ寸法に形成されている場合に必要である。 Thereafter, the thermostat insertion portion 16d and the block material insertion port 16e are punched into desired positions of the heat insulating material 16 corresponding to the meandering section of the heater wire 18. This punching process of the thermostat insertion portion 16d is necessary when the thermostat 21 (shown in FIG. 5) having a thermal fuse is formed to have substantially the same dimension as the thickness of the heat insulating material 16.

一方、予めヒータ線１８を、上記断熱材１６の上面に加熱加圧により形成したヒータ線収納溝１６ａの形状に合致させた配線形状、つまり所定の間隔をあけて蛇行する配線形状（図５参照）に仮り加工しておく。 On the other hand, the wiring shape in which the heater wire 18 is matched with the shape of the heater wire housing groove 16a formed in advance on the upper surface of the heat insulating material 16 by heating and pressurization, that is, the wiring shape meandering at a predetermined interval (see FIG. 5). ) Is temporarily processed.

次いで、図６（ａ）に示すように、ブロック材用挿通口２３ａが打ち抜き加工されている均熱板２３を加熱し、その加熱した均熱板２３に、上記予め配線形状に仮り加工しておいたヒータ線１８を載置し、外被１８ｂの熱溶着により均熱板２３に固着して配線する。また、上記導線１６及び送り線２０も同様に均熱板２３に所定の位置に固着して配線する。このように、ヒータ線１８と均熱板２３とを予め一体に固着しておくことで、埋込パネル部材１５の生産性が一層高められる上、ヒータ線１８の熱が確実かつ均一に均熱板２３に伝達できる。しかも、各線１８〜２０は、加熱した均熱板２３に外被１８ｂ〜２０ｂを溶融させることで、配線形状を維持した状態に固着されるので、特別な接着剤等を用いなくとも各線１８〜２０が均熱板２３に簡単に固着され、埋込パネル部材１５の生産性を図る上で非常に有利なものとなる。 Next, as shown in FIG. 6 (a), the soaking plate 23 in which the block material insertion opening 23a is punched is heated, and the heated soaking plate 23 is preliminarily processed into the above-described wiring shape. The placed heater wire 18 is placed, and is fixedly wired to the heat equalizing plate 23 by thermal welding of the jacket 18b. Similarly, the conductive wire 16 and the feed wire 20 are fixedly attached to the heat equalizing plate 23 at predetermined positions. Thus, by fixing the heater wire 18 and the soaking plate 23 together in advance, the productivity of the embedded panel member 15 can be further improved, and the heat of the heater wire 18 can be soaked reliably and uniformly. It can be transmitted to the plate 23. In addition, since each of the wires 18 to 20 is fixed in a state in which the wiring shape is maintained by melting the jackets 18b to 20b on the heated soaking plate 23, each of the wires 18 to 20 can be used without using a special adhesive or the like. 20 is easily fixed to the soaking plate 23, which is very advantageous for improving the productivity of the embedded panel member 15.

図６（ｂ）に示すように、外殻部材１を表面部２が下向きとなり裏面の空洞部１０が上向きに開口するように反転させる。この状態では、その空洞部１０内の底面に起立している複数のブロック材８，８，…が上向きに突出した状態となる。 As shown in FIG. 6B, the outer shell member 1 is inverted so that the front surface portion 2 faces downward and the cavity 10 on the back surface opens upward. In this state, a plurality of block members 8, 8,... Standing on the bottom surface in the hollow portion 10 protrude upward.

この空洞部１０内に、まず、上記工程でヒータ線１８、導出線１９及び送り線２０をそれぞれ溶融固着して配線した均熱板２３を空洞部１０の開口部から各線１８〜２０の固着側が上向きとなるように空洞部１０内の底面上（表面部２の裏面側）に載置して組み込む。そのとき、空洞部１０内の底面に立設されている各ブロック材８を均熱板２３のブロック材用挿通口２３ａに挿通させる。 First, the heat equalizing plate 23 in which the heater wire 18, the lead-out wire 19, and the feed wire 20 are respectively melted and fixed in the above-described process in the hollow portion 10 is connected to the fixing side of the wires 18 to 20 from the opening of the hollow portion 10. It is mounted on the bottom surface in the cavity portion 10 (the back surface side of the front surface portion 2) so as to face upward. At that time, each block member 8 erected on the bottom surface in the hollow portion 10 is inserted into the block member insertion port 23 a of the heat equalizing plate 23.

しかる後、図６（ｃ）に示すように、上記外殻部材１の空洞部１０内側に開口部から、上記工程で得た断熱材１６をその各収納溝１６ａ〜１６ｃ側を下向けた状態で、先に組み込んだ均熱板２３上の各線１８〜２０が各収納溝１６ａ〜１６ｃに収納されるように、また断熱材１６のサーモスタット用挿通部１６ｄにサーモスタット２１が収納されるように埋め込む。また、その断熱材１６のブロック材用挿通口１６ｅには、上記対応するブロック材８を挿通させる。これにより、予め、断熱材１６の各収納溝１６ａ〜１６ｃの配線形状と合致する形状に形成した各線１８〜２０が各収納溝１６ａ〜１６ｃに容易に収納される。そのため、断熱材１６の上面側に複雑なルーターによる溝加工や埋め込み作業を行う必要がない。しかも、発泡性合成樹脂液を発泡硬化させる場合における大掛かりな設備も不要となるため、埋込パネル部材１５を極めて生産性良く形成できる。 Thereafter, as shown in FIG. 6 (c), the heat insulating material 16 obtained in the above process is directed downward from the opening inside the hollow portion 10 of the outer shell member 1 with its storage grooves 16a to 16c facing downward. Then, the wires 18 to 20 on the soaking plate 23 previously assembled are accommodated in the accommodating grooves 16a to 16c, and the thermostat 21 is accommodated in the thermostat insertion portion 16d of the heat insulating material 16. . Further, the corresponding block material 8 is inserted into the block material insertion port 16 e of the heat insulating material 16. Accordingly, the wires 18 to 20 formed in advance in a shape matching the wiring shape of the storage grooves 16a to 16c of the heat insulating material 16 are easily stored in the storage grooves 16a to 16c. Therefore, it is not necessary to perform a groove processing or embedding work by a complicated router on the upper surface side of the heat insulating material 16. Moreover, since no large-scale equipment is required when foaming and curing the foamable synthetic resin liquid, the embedded panel member 15 can be formed with extremely high productivity.

そして、このようにして埋込パネル部材１５が、外殻部材１の空洞部１０内に容易に組み込まれることになり、ヒータ線方式の電気式暖房床パネルＡを簡単に生産することができる。 In this manner, the embedded panel member 15 is easily incorporated into the cavity 10 of the outer shell member 1, and the heater wire type electric heating floor panel A can be easily produced.

次いで、図６（ｄ）に示すように、外殻部材１の周辺部に位置する枠部３の上面（裏面）と各ブロック材８の上面（先端面）とにそれぞれ接着剤を塗布し、その上からバッカー材２６を載置して固着する。 Next, as shown in FIG. 6 (d), an adhesive is applied to each of the upper surface (back surface) of the frame portion 3 and the upper surface (tip surface) of each block member 8 located in the peripheral portion of the outer shell member 1, The backer material 26 is placed and fixed from above.

そして、外殻部材１を、表面部２が上側に、またバッカー材２６が下側にそれぞれ位置するように上下反転させた後、上記表面部２の外面（上面）に好みに応じた表面仕上げ材１２を張り付けることで、図１に示す暖房床パネルＡを得る。尚、予め表面仕上げ材２を貼り付けた外殻部材１に埋込パネル部材１５の収納作業を行ってもかまわない。 Then, after the outer shell member 1 is turned upside down so that the surface portion 2 is located on the upper side and the backer material 26 is located on the lower side, the outer surface (upper surface) of the surface portion 2 is surface-finished according to preference. By sticking the material 12, the heated floor panel A shown in FIG. 1 is obtained. It should be noted that the embedding panel member 15 may be housed in the outer shell member 1 to which the surface finishing material 2 is previously attached.

（6）暖房床パネルの施工方法
以上の構成を持つ暖房床パネルＡは、バッカー材２６の裏面（下面）において各ブロック材８の位置する目印が設けられている部分、及び周辺部の少なくとも一部分に接着剤を塗布し、図２に示すように、床下地材Ｂ上に並べて施工する。そのとき、隣接する１対の暖房床パネルＡ，Ａの一方の外殻部材１の雌実部４，６に他方の暖房床パネルＡの外殻部材１の雄実部５，７が嵌合されて施工される。 (6) Heating floor panel construction method The heating floor panel A having the above-described configuration is a portion where the mark where each block material 8 is located on the back surface (lower surface) of the backer material 26 and at least a part of the peripheral portion. Then, the adhesive is applied to the floor base material B, as shown in FIG. At that time, the male real parts 5 and 7 of the outer shell member 1 of the other heating floor panel A are fitted to the female real parts 4 and 6 of one outer shell member 1 of the pair of adjacent heating floor panels A and A. To be constructed.

したがって、この実施形態においては、暖房床パネルＡにおける外殻部材１の裏面に周辺部を残して凹陥状の空洞部１０が形成され、この空洞部１０内に埋込パネル部材１５が格納されて、空洞部１０は外殻部材１の周辺部裏面に接着したバッカー材２６により封閉される。そして、空洞部１０内の底面に複数のブロック材８，８，…が突設され、この各ブロック材８は埋込パネル部材１５における断熱材１６及び均熱板２３の挿通口１６ｅ，２３ａを挿通した後、その先端面がバッカー材２６に一体的に接着されているので、外殻部材１において周辺部の枠部３以外の中間部に位置する表面部２はブロック材８を介してバッカー材２６に連結されることになる。また、このバッカー材２６は施工によって床下地材Ｂに接着固定され、そのうちブロック材８のある位置でも接着される。このことで、外殻部材１の表面部２がバッカー材２６及び床下地材Ｂによって補強され、その表面部２が吸湿による伸長差によって表面側に膨出変形するのを確実に防止することができる。 Therefore, in this embodiment, the recessed hollow portion 10 is formed on the back surface of the outer shell member 1 in the heating floor panel A leaving the peripheral portion, and the embedded panel member 15 is stored in the hollow portion 10. The cavity 10 is sealed with a backer material 26 adhered to the back surface of the peripheral part of the outer shell member 1. A plurality of block members 8, 8,... Project from the bottom surface of the cavity portion 10, and each block member 8 passes through the heat insulating material 16 in the embedded panel member 15 and the insertion openings 16 e and 23 a of the soaking plate 23. After the insertion, the front end surface of the outer shell member 1 is integrally bonded to the backer material 26, so that the surface portion 2 located in the intermediate portion other than the peripheral frame portion 3 in the outer shell member 1 is backed by the block material 8. It will be connected to the material 26. In addition, the backer material 26 is bonded and fixed to the floor base material B by construction, and is also bonded at a position where the block material 8 is present. In this way, the surface portion 2 of the outer shell member 1 is reinforced by the backer material 26 and the floor base material B, and the surface portion 2 can be reliably prevented from bulging and deforming to the surface side due to a difference in elongation due to moisture absorption. it can.

（実施形態２）
図９は本発明の実施形態２を示し（尚、図１〜図８と同じ部分については同じ符号を付してその詳細な説明は省略する）、ブロック材８を直接に床下地材Ｂに接着できるようにしたものである。 (Embodiment 2)
FIG. 9 shows a second embodiment of the present invention (note that the same parts as those in FIGS. 1 to 8 are given the same reference numerals and detailed description thereof is omitted), and the block material 8 is directly applied to the floor base material B. It can be bonded.

すなわち、この実施形態では、バッカー材２６において、その少なくともブロック材８に対応した部分に貫通孔２７が抜き加工され、この貫通孔２７はブロック材８の先端面よりも小さい大きさに設定されている。そして、ブロック材８の先端面は上記貫通孔２７を除いた部分でバッカー材２６に接着されている。その他の構成は上記実施形態１と同様である。 That is, in this embodiment, a through hole 27 is punched in at least a portion corresponding to the block material 8 in the backer material 26, and the through hole 27 is set to a size smaller than the tip end surface of the block material 8. Yes. The tip surface of the block material 8 is bonded to the backer material 26 at a portion excluding the through hole 27. Other configurations are the same as those of the first embodiment.

したがって、この実施形態においては、暖房床パネルＡの施工時にバッカー材２６を床下地材Ｂに接着するとき、ブロック材８をもバッカー材２６の貫通孔２７を介して床下地材Ｂに直接に接着することができる。そのため、外殻部材１において周辺部以外の中間部に位置する表面部をブロック材８及びバッカー材２６を介して床下地材Ｂに連結して、外殻部材１の表面部が表面側に膨出変形するのをより一層確実に防止することができる。 Therefore, in this embodiment, when the backer material 26 is bonded to the floor base material B during the construction of the heating floor panel A, the block material 8 is also directly attached to the floor base material B through the through holes 27 of the backer material 26. Can be glued. For this reason, the outer shell member 1 is connected to the floor base material B through the block material 8 and the backer material 26 so that the surface portion located in the intermediate portion other than the peripheral portion is swelled to the surface side.

（環境試験）
以上の各実施例及び各比較例について、財団法人日本建築総合試験所環境試験室において、一定期間の養生後、一定の条件下で定時的に乾燥及び吸湿を繰り返して、乾湿条件を切り換え、そのときの外殻部材の表面部の反りを測定した。 (Environmental testing)
For each of the above Examples and Comparative Examples, in the Environmental Laboratory of the Japan Building Research Institute, after drying for a certain period of time, drying and moisture absorption are repeated regularly under certain conditions, and the wet and dry conditions are switched. The warpage of the surface portion of the outer shell member was measured.

すなわち、暖房床パネルの長さ方向に沿って並んだ５点の位置における外殻部材の表面の膨れ量を測定した。具体的には、５点の測定位置の各々について、デジタルゲージを外殻部材表面の幅方向両側の周辺部（枠部）に当て、その表面の幅方向中央部分の膨れ量を測定し、５点の測定値の平均を算出して比較した。５点の測定位置とは、実施例１及び２においては、暖房床パネルの長さ方向に並んで配置されたブロック材の位置であり、比較例１及び２では、実施例に対応する同様の位置である。その結果を図１０及び図１１に示す。 That is, the amount of swelling of the surface of the outer shell member at five positions aligned along the length direction of the heating floor panel was measured. Specifically, at each of the five measurement positions, a digital gauge is applied to the peripheral portions (frame portions) on both sides in the width direction of the outer shell member surface, and the amount of swelling at the center portion in the width direction of the surface is measured. The average of the measured points was calculated and compared. The five measurement positions are the positions of the block members arranged side by side in the length direction of the heating floor panel in Examples 1 and 2, and in Comparative Examples 1 and 2, similar positions corresponding to the examples are used. Position. The results are shown in FIGS.

この図１０及び図１１によれば、実施例１と比較例１とを比較したとき、或いは実施例２と比較例２とを比較したとき、床下地材が合板であるかパーティクルボードであるかで伸び縮みの変動幅が異なり、合板よりもパーティクルボードの方が乾湿による伸び縮みの変動幅が大きく、太鼓状の変形が起き易いことが判る。 According to FIGS. 10 and 11, when Example 1 and Comparative Example 1 are compared, or when Example 2 and Comparative Example 2 are compared, whether the floor base material is plywood or particle board. It can be seen that the fluctuation range of expansion and contraction is different, and that the fluctuation range of expansion and contraction due to wet and dry is larger in the particle board than in the plywood, and the drum-like deformation is likely to occur.

しかし、いずれにしても、本発明に係る実施例１及び２の方が比較例１及び２に比べ、乾湿による伸び縮みの変動幅が小さく、太鼓状の変形が起き難いことが裏付けられた。 However, in any case, it was confirmed that Examples 1 and 2 according to the present invention had a smaller fluctuation range of expansion and contraction due to wet and dry than Comparative Examples 1 and 2, and it was difficult for drum-like deformation to occur.

本発明は、電気式の暖房床パネルを変形することなく長期間に亘り安定して使用できるので、極めて有用で産業上の利用可能性が高い。 Since the present invention can be used stably over a long period of time without deforming an electric heating floor panel, it is extremely useful and has high industrial applicability.
