Description

【0001】
【発明の属する技術分野】
本発明は建物の床暖房装置とそれに使用される蓄熱体および蓄熱体の製造方法に関する。
【0002】
【従来の技術】
従来の建物の床暖房装置は床支持体の上に発熱パネルを搭載し、発熱パネルの上に床仕上材を敷設し、電力が発熱パネルに供給されることで、発熱パネルが熱を発生し、その熱が床仕上材を暖めている(例えば、特許文献1参照)。
【0003】
【特許文献1】
特開2003−21349号公報(第1頁、要約、図1)
【0004】
【発明が解決しようとする課題】
しかしながら、従来例は人の歩く床仕上材を発熱パネルで直接的に暖める構造であるため、例えば、2階建て以上の建物の場合には、2階以上における部屋ごとの床仕上材にも発熱パネルを敷設する必要があるという問題点があった。
【0005】
そこで、本発明は、建物の基礎に温媒循環式の蓄熱体を設けることで、上層階の部屋ごとに蓄熱体を設けることなく、下層階と上層階との部屋ごとを適切に暖めることができる床暖房装置とそれに使用する蓄熱体および蓄熱体の製造方法を提供するものである。
【0006】
【課題を解決するための手段】
本発明に係る床暖房装置は、建物の基礎に硬質断熱材を介在させて蓄熱体を基礎の上に構築される建物における部屋の床との間に空間を存在させた形態に設け、蓄熱体の内部と建物の外部に設置したボイラーとに当該ボイラーで加熱された温媒を循環することで蓄熱体を暖めることによって、上層階の部屋ごとに蓄熱体を設けることなく、下層階と上層階との部屋ごとを適切に暖めることができる。本発明に係る床暖房装置に使用される蓄熱体は温媒を循環する輸送管を蛇行配管して埋設したコンクリートを主材料としたことによって、蓄熱体が輸送管から伝達された熱で全体的に一様に暖められ、その暖められた蓄熱体が蓄熱体の上に空間を介して設けられた建物における部屋の床を全体的に一様に暖めることができる。本発明に係る蓄熱体の製造方法は現場で基礎の上に敷設された硬質断熱材の上に輸送管が蛇行配管された後に、蓄熱体の主材料であるコンクリートが現場打ちされることによって、工場生産された蓄熱体を現場に運んで設置する場合に比べ、基礎の蓄熱体を設けるべき位置に蓄熱体を適切に設置することができる。
【0007】
【発明の実施の形態】
図1から図3は一実施形態であって、図1は床暖房装置21における蓄熱体26を縦方向に切断した断面を示し、図2は建物1における1階の各部屋6に対する輸送管25の平面的な配管を示し、図3は建物1を縦方向に切断した断面を示す。
【0008】
図3を参照し、第1種換気装置11および床暖房装置21を備えた建物1について2階建ての家屋を例として説明する。建物1はべた基礎と呼ばれるコンクリートからなる基礎2の上に柱3を建て、柱3の上に屋根4を載せ、柱3の外側に外壁5を形成し、柱3と屋根4および外壁5で囲まれた内部に下層階である1階の部屋6と上層階である2階の部屋6とを備える。図示は省略したが、建物1は外壁5の内側および屋根4の内側に図外の断熱材を敷設した外断熱構造になっている。
【0009】
第1種換気装置11は熱交換換気機器12と吸気管15および排気管17を備える。熱交換換気機器12は図外のフィルタとモータとファンおよび熱交換体を内蔵した構造であって、部屋6を形成する内壁7と外壁5との間に形成された空間Aに配置されて外壁5に取り付けられる。熱交換換気機器12の屋外吸気口13と屋外排気口14は外壁5を貫通して外壁5の外側に突出する。熱交換換気機器12における図外の屋内吸気口に接続された吸気管15は内壁7と外壁5との間に形成された空間Aを経由して基礎2と1階の部屋6における床8との間に形成された空間Bに配管される。吸気管15は床暖房装置21の蓄熱体26に対応する吹出口16を備える。熱交換換気機器12における図外の屋内排気口に接続された排気管17は内壁7と外壁5との間に形成された空間Aを経由して屋根裏Dに配管される。排気管17には屋根裏Dや1階の部屋6における天井および2階の部屋6における天井のそれぞれに開口された吸込口18を備える。1階および2階の部屋6のそれぞれにおける内壁7には吸込口19が部屋6の内壁7における下部に形成される。
【0010】
そして、第1種換気装置11にあっては、熱交換換気機器12のモータがファンを回転することで、屋外の外気が屋外吸気口13から吸い込まれてフィルタで塵埃を除去され、この塵埃の除去された外気が吸気管15を経由して吹出口16から蓄熱体26に向けて吹き出される。この吹出口16から吹き出された外気は蓄熱体26に接触し、蓄熱体26で暖められた内気となる。この温められた内気の一部は各部屋6の吸込口19から部屋6に導入され、各部屋6の暖かな内気の一部が各部屋6の天井における吸込口18に吸い込まれる。また、上記蓄熱体26で暖められた内気の別の一部が各部屋6の内壁7どうしの間に形成された空間Cや各部屋6の内壁7と外壁5との間に形成された空間Aを経由して屋根裏Dにおける吸込口18に吸い込まれる。このように蓄熱体26で温められた清浄な内気が矢印で示すように建物1の内部を循環して1階および2階の部屋6を内側および外側から温めるので、暖房の必要な季節において、塵埃の除去されて暖められた内気の循環で健康的に暖房された居住空間を作ることができる。上記吸込口18に吸い込まれた内気が排気管17を経由して屋外排気口14から屋外に排出される場合に、熱交換換気機器12における熱交換体が排気管17から屋外排気口14に送られる内気の熱と屋外吸気口13から吸気管15に送られる外気の熱とを交換する。このように吹出口16から蓄熱体26に吹き付けられる外気が熱交換換気機器12による内気との熱交換で温められているので、外気を温める蓄熱体26の負担が軽減される。
【0011】
床暖房装置21は水と不凍液との混合された温媒を閉鎖管路に循環させる構造であって、ボイラー22と輸送管25および蓄熱体26を備える。ボイラー22は図外の熱源とモータとポンプと熱交換器および制御部を備えた構造であって、屋外に設置される。蓄熱体26は基礎2における1階の部屋6と対応して設けられる。輸送管25の一端はボイラー22の吐出口23に接続され、輸送管25の他端はボイラー22の取入口24に接続され、輸送管25の中間部は蓄熱体26に埋設される。ボイラー22のポンプおよび熱交換器や輸送管25には温媒が封入されている。熱交換管を加熱するボイラー22の熱源としては電気でもよいが、灯油のような燃料を使用すればボイラー22の維持費が電気よりも安くなる。そして、床暖房装置21では、ボイラー22のモータがポンプを駆動することで、温媒が輸送管25からボイラー22の熱交換管に送られ、熱源で加熱された熱交換管が温媒を暖め、暖められた温媒が輸送管25で蓄熱体26に送られて蓄熱体26を暖める一方、蓄熱体26で熱を奪われて冷えた温媒が輸送管25からボイラー22の熱交換管に送られる。ポンプと熱交換管および輸送管25が上記閉鎖管路を形成する。ボイラー22の制御部は蓄熱体26と1階の部屋6の床8との間における空間Bに設置された図外の温度感知器から入力された検出温度が人の操作で制御部に設定された目標温度となるように熱源をフィードバック制御する。例えば、人が目標温度を例えば23℃と設定した場合、制御部は検出温度が目標温度よりも低ければ熱源を駆動し、その熱源の駆動後に、検出温度が目標温度より例えば2℃高い温度に到達すると、熱源の駆動を停止し、その熱源の停止後に、検出温度が目標温度より例えば2℃低い温度に到達すると、熱源を駆動するというようになっている。
【0012】
よって、床暖房装置21の温媒で暖められた蓄熱体26が第1種換気装置11の熱交換換気機器12で暖められて蓄熱体26に向けて吹き出された外気を暖めることで、暖められた内気を作る。この暖められた内気の一部は各部屋6の内装の周囲に形成された空間A;B;Cを経由して屋根裏Dに向けて上昇する過程で、各部屋6の内装を暖める。また、上記蓄熱体26で暖められた内気の別の一部は各部屋6の吸込口18から各部屋6に導入される。このように、第1種換気装置11による空気の流れと床暖房装置21による暖気生成との有機的な組み合わせによって、暖房の必要な季節に、各部屋6を快適な居住空間にすることができる。床暖房装置21が輸送管25とボイラー22とに封入されて循環する温媒をボイラー22の熱交換器で暖める構造であるので、温媒を暖めるボイラー22における熱源の消費量を低減することができる。
【0013】
図1を参照し、床暖房装置21における蓄熱体26の内部構造について説明する。硬質断熱材27が基礎2における一方の基礎部28と他方の基礎部28とこれらの基礎部28に連接されたスラブ部29との内側に敷設される。硬質断熱材27は封袋にガラスウールのような断熱材繊維を密封したような圧縮性に富む形態ではなく、断熱材料を樹脂成形で工場生産された圧縮されづらい形態に形成された押出発泡ポリスチレンフォームのような板状であって、その板状の硬質断熱材27が現場で養生の終わった基礎2に施工される。硬質断熱材27の上には鉄筋としてのワイヤメッシュ30が敷設される。輸送管25は例えば三菱産資株式会社製の商品名Oストップたる架橋ポリエチレン管が使用され、ワイヤメッシュ30の上に蛇行した配管形態で敷設される。ワイヤメッシュ30に敷設された輸送管25は軟鉄からなる図外の結束線でワイヤメッシュ30に結束されることによって、輸送管25がワイヤメッシュ30に固定される。
【0014】
ワイヤメッシュ30の上に敷設された輸送管25の両端部は基礎部28に上端面から下方に窪むように形成された切欠部32および硬質断熱材27に形成され貫通孔33から隣のスラブ部29の方向に引き出される。その状態において、蓄熱体26の材料であるコンクリートが現場打ちされる。具体的には、蓄熱体26の材料である混練された生コンのようなコンクリートが硬質断熱材27で囲まれた空間に流し込まれて養生されることで、ワイヤメッシュ30と輸送管25および結束線をコンクリートに埋め込んだ形態の蓄熱体26が形成される。基礎部28は図3における建物1の土台を載せる部分である。スラブ部29は図3における各部屋6の床8と空間Bを形成しつつ上下方向に対応する部分である。切欠部32は貫通孔であってもよいが、上方の開放された切欠部32であれば、輸送管25の中間部を上方から切欠部32に挿入すればよいので、輸送管25の一端から挿入しなければならない貫通孔に比べて、輸送管25の配管作業が容易である。貫通孔33は上方の開方された切欠部であってもよいが、上方の閉鎖された貫通孔33であれば、貫通孔33の周りの硬質断熱材27が空間に流し込まれた蓄熱体26の材料であるコンクリートを基礎部28の方に溢れ出ないように型枠の働きを行う。蓄熱体26がべた基礎と呼ばれる基礎2に硬質断熱材27を介在させて形成されているので、地面からの湿気による影響を受けない。蓄熱体26と基礎2のスラブ部29との間に配置された断熱材が硬質断熱材27であるので、蓄熱体26の材料である生コンのようなコンクリートが現場打ちされる場合に硬質断熱材27が当該現場打ちされるコンクリートに対しワイヤメッシュ30や輸送管25を設置形態で適切な位置に支持することができる。硬質断熱材27の上に図外のスペーサを置き、そのスペーサの上にワイヤメッシュ30を置くことで、ワイヤメッシュ30および輸送管25を蓄熱体26の内部に埋め込む形態であっても、同様に適用することができる。
【0015】
図2を参照し、建物1における1階の各部屋6に対する輸送管25の配管について説明する。輸送管25はボイラー22の吐出口23から基礎部28および硬質断熱材27(図1参照)を外側から或る1つの部屋6と対応する部分の側に貫通し、その1つの部屋6と対応する部分で蛇行しつつ配管された後、当該1つの部屋6と隣のもう1つの部屋6との境にある基礎部28および硬質断熱材27を貫通して隣の1つの部屋6と対応する部分で蛇行しつつ配管された後、上記隣の1つの部屋6と更なる隣の1つの部屋6との境にある基礎部28および硬質断熱材27を貫通して更なる隣の1つの部屋6と対応する部分で蛇行しつつ配管されというように、各部屋6と対応する部分で蛇行しつつ配管され、最後の部屋6と対応する部分から基礎部28および硬質断熱材27を外側に貫通してボイラー22の取入口24に至る。各部屋6と対応する部分において、野菜の熱的な劣化を防止するために、輸送管25は台所の野菜を収納する部分に配管されない。また、輸送管25が居間や食堂などの人の行き交う部分や座る部分および寝る部分などの居住部分には蛇行する輸送管25どうしの間隔を均等となるように配管されることで、居住部分を一様な温度で全体的に温めることができる。よって、蓄熱体26が蛇行配管された輸送管25から伝達された熱で全体的に一様に暖められ、その暖められた蓄熱体26が蓄熱体26の上に空間Bを介して設けられた建物1における1階の部屋6の床8を全体的に一様に暖めることができる。図2において、34は玄関の土間、35は便所、36は洗面所、37は浴室、39はキッチンセットを示す。
【0016】
上記のように基礎2の作られた建築現場において、硬質断熱材27の設置、ワイヤメッシュ30の設置、輸送管25の配管、図外の結束線による結束、生コンのようなコンクリートの打設などの施工を順に行うことによって、蓄熱体26が現場で作られるので、工場生産された蓄熱体26を現場に運んで設置する場合に比べ、蓄熱体26が基礎2の蓄熱体26を設けるべき位置に適切に設置できる。

[0003]
[Patent Document 1]
JP-A-2003-21349 (page 1, abstract, FIG. 1)
[0004]
[Problems to be solved by the invention]
However, since the conventional example has a structure in which the floor covering for human walking is directly heated by the heat generating panel, for example, in the case of a building having two or more floors, the floor covering for each room on the second floor or above also generates heat. There was a problem that panels had to be laid.
[0005]
Therefore, the present invention provides a heat medium circulating type heat storage unit at the foundation of a building, so that it is possible to appropriately heat each room of the lower floor and the upper floor without providing a heat storage unit for each room of the upper floor. An object of the present invention is to provide a floor heating device that can be used, a heat storage body used for the same, and a method of manufacturing the heat storage body.
[0006]
[Means for Solving the Problems]
The floor heating device according to the present invention is provided with a form in which a space exists between a floor and a room of a building in a building constructed on a foundation by interposing a hard heat insulating material on the foundation of the building. By circulating the heating medium heated by the boiler between the inside of the building and the boiler installed outside the building, the heat storage body is warmed, so that the lower floor and the upper floor are not provided for each room of the upper floor. And each room can be properly warmed. The heat storage body used in the floor heating device according to the present invention is mainly made of concrete buried in a meandering pipe in a transport pipe for circulating a heating medium, so that the heat storage body is entirely formed of heat transferred from the transport pipe. And the heated regenerator can uniformly uniformly warm the floor of a room in a building provided on the regenerator via a space. The method for manufacturing a heat storage element according to the present invention is that, after the transport pipe is meandering on a hard heat insulating material laid on a foundation at the site, concrete, which is a main material of the heat storage element, is cast in place, Compared to a case where a heat storage element produced in a factory is carried to the site and installed, the heat storage element can be appropriately installed at a position where the base heat storage element should be provided.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
1 to 3 show one embodiment, FIG. 1 shows a cross section of a heat storage body 26 in a floor heating device 21 cut in a vertical direction, and FIG. 2 shows a transport pipe 25 for each room 6 on the first floor of the building 1. 3 shows a cross section of the building 1 cut in the vertical direction.
[0008]
Referring to FIG. 3, a description will be given of a building 1 including a first-class ventilation device 11 and a floor heating device 21 by taking a two-story house as an example. In the building 1, a pillar 3 is built on a concrete foundation 2 called solid foundation, a roof 4 is placed on the pillar 3, an outer wall 5 is formed outside the pillar 3, and the pillar 3, the roof 4 and the outer wall 5 are used. A first floor room 6 which is a lower floor and a second floor room 6 which is an upper floor are provided in the enclosed area. Although not shown, the building 1 has an external heat insulating structure in which a heat insulating material (not shown) is laid inside the outer wall 5 and the roof 4.
[0009]
The first type ventilation device 11 includes a heat exchange ventilation device 12, an intake pipe 15 and an exhaust pipe 17. The heat exchange ventilator 12 has a structure in which a filter, a motor, a fan, and a heat exchanger (not shown) are built in, and is disposed in a space A formed between the inner wall 7 and the outer wall 5 forming the room 6 and the outer wall is formed. 5 is attached. The outdoor air inlet 13 and the outdoor air outlet 14 of the heat exchange ventilation device 12 penetrate the outer wall 5 and protrude outside the outer wall 5. An intake pipe 15 connected to an indoor intake port (not shown) of the heat exchange ventilator 12 passes through the space A formed between the inner wall 7 and the outer wall 5 and the base 2 and the floor 8 in the room 6 on the first floor. Is piped to the space B formed between them. The intake pipe 15 has an outlet 16 corresponding to the heat storage 26 of the floor heating device 21. An exhaust pipe 17 connected to an indoor exhaust port (not shown) of the heat exchange ventilator 12 is piped to the attic D via a space A formed between the inner wall 7 and the outer wall 5. The exhaust pipe 17 is provided with a suction port 18 that is opened to the attic D, the ceiling in the room 6 on the first floor, and the ceiling in the room 6 on the second floor. A suction port 19 is formed in the lower part of the inner wall 7 of the room 6 on the inner wall 7 in each of the rooms 6 on the first floor and the second floor.
[0010]
In the type 1 ventilation device 11, when the motor of the heat exchange ventilation device 12 rotates the fan, the outdoor air is sucked from the outdoor air inlet 13 and the dust is removed by the filter. The removed outside air is blown from the air outlet 16 toward the heat storage body 26 via the intake pipe 15. The outside air blown out from the outlet 16 comes into contact with the heat storage body 26 and becomes the inside air warmed by the heat storage body 26. A part of the heated inside air is introduced into the room 6 from the suction port 19 of each room 6, and a part of the warm inside air of each room 6 is sucked into the suction port 18 on the ceiling of each room 6. Further, another part of the inside air warmed by the heat storage body 26 is a space C formed between the inner walls 7 of each room 6 and a space formed between the inner wall 7 and the outer wall 5 of each room 6. Via A, it is sucked into the suction port 18 in the attic D. In this way, the clean inside air warmed by the heat storage unit 26 circulates through the inside of the building 1 as shown by the arrows to warm the rooms 6 on the first and second floors from inside and outside, so that in the season when heating is necessary, A healthy heated living space can be created by the circulation of warm air, which is free from dust. When the inside air sucked into the suction port 18 is exhausted outside from the outdoor exhaust port 14 via the exhaust pipe 17, the heat exchanger in the heat exchange ventilation device 12 is sent from the exhaust pipe 17 to the outdoor exhaust port 14. The heat of the inside air is exchanged with the heat of the outside air sent from the outdoor intake port 13 to the intake pipe 15. Since the outside air blown from the outlet 16 to the heat storage body 26 is heated by the heat exchange with the inside air by the heat exchange ventilation device 12, the load on the heat storage body 26 that warms the outside air is reduced.
[0011]
The floor heating device 21 has a structure for circulating a heating medium in which water and antifreeze are mixed through a closed conduit, and includes a boiler 22, a transport pipe 25, and a heat storage element 26. The boiler 22 has a structure including a heat source (not shown), a motor, a pump, a heat exchanger, and a control unit, and is installed outdoors. The heat storage body 26 is provided corresponding to the room 6 on the first floor of the foundation 2. One end of the transport pipe 25 is connected to a discharge port 23 of the boiler 22, the other end of the transport pipe 25 is connected to an inlet 24 of the boiler 22, and an intermediate portion of the transport pipe 25 is embedded in the heat storage body 26. A warm medium is sealed in the pump, heat exchanger, and transport pipe 25 of the boiler 22. Electricity may be used as a heat source of the boiler 22 for heating the heat exchange tubes. However, if a fuel such as kerosene is used, the maintenance cost of the boiler 22 is lower than that of electricity. Then, in the floor heating device 21, the motor of the boiler 22 drives the pump, so that the heating medium is sent from the transport pipe 25 to the heat exchange pipe of the boiler 22, and the heat exchange pipe heated by the heat source warms the heating medium. The heated medium is sent to the regenerator 26 by the transport tube 25 to warm the regenerator 26, while the heated medium deprived of heat by the regenerator 26 is transferred from the transport tube 25 to the heat exchange tube of the boiler 22. Sent. The pump, the heat exchange pipe and the transport pipe 25 form the closed conduit. The control unit of the boiler 22 sets the detected temperature input from a temperature sensor (not shown) installed in the space B between the heat storage unit 26 and the floor 8 of the room 6 on the first floor by a human operation. The feedback control of the heat source is performed so as to reach the target temperature. For example, when a person sets the target temperature to, for example, 23 ° C., the control unit drives the heat source if the detected temperature is lower than the target temperature, and after the driving of the heat source, the detected temperature is increased to, for example, 2 ° C. higher than the target temperature. When the temperature reaches, the driving of the heat source is stopped. When the detected temperature reaches, for example, 2 ° C. lower than the target temperature after the stopping of the heat source, the heat source is driven.
[0012]
Therefore, the heat storage body 26 warmed by the heating medium of the floor heating device 21 is heated by the heat exchange ventilation device 12 of the first type ventilation device 11 and warms the outside air blown out toward the heat storage body 26, thereby being heated. Create a shy atmosphere. A part of the heated inside air warms the interior of each room 6 in the process of rising toward the attic D via the spaces A, B, and C formed around the interior of each room 6. Another part of the inside air warmed by the heat storage body 26 is introduced into each room 6 from the suction port 18 of each room 6. As described above, by the organic combination of the air flow by the first type ventilation device 11 and the generation of warm air by the floor heating device 21, each room 6 can be made a comfortable living space during the season when heating is required. . Since the floor heating device 21 has a structure in which the heating medium circulated while being enclosed in the transport pipe 25 and the boiler 22 is heated by the heat exchanger of the boiler 22, it is possible to reduce the consumption of the heat source in the boiler 22 for heating the heating medium. it can.
[0013]
The internal structure of the heat storage unit 26 in the floor heating device 21 will be described with reference to FIG. A hard heat insulating material 27 is laid inside one base part 28 and the other base part 28 of the base 2 and a slab part 29 connected to these base parts 28. The rigid heat insulating material 27 is not formed in a highly compressible form in which a heat insulating material such as glass wool is sealed in a sealing bag. A plate-like rigid heat insulating material 27 having a plate shape like a foam is applied to the foundation 2 that has been cured on site. A wire mesh 30 as a reinforcing bar is laid on the hard heat insulating material 27. Transport tube 25, for example Mitsubishi production capital K.K. O 2 stop serving crosslinked polyethylene pipes are used, is laid in a pipe form meanders over the wire mesh 30. The transport pipe 25 laid on the wire mesh 30 is bound to the wire mesh 30 by a binding wire (not shown) made of soft iron, so that the transport pipe 25 is fixed to the wire mesh 30.
[0014]
The both ends of the transport pipe 25 laid on the wire mesh 30 are cut out 32 formed in the base 28 so as to be depressed downward from the upper end face, and the slab 29 formed in the hard heat insulating material 27 through the through hole 33. It is pulled out in the direction of. In that state, concrete, which is the material of the heat storage body 26, is cast in place. More specifically, concrete such as kneaded raw concrete, which is a material of the heat storage body 26, is poured into a space surrounded by the hard heat insulating material 27 and cured, so that the wire mesh 30, the transport pipe 25, and the binding wire are formed. Is embedded in concrete to form a heat storage body 26. The base portion 28 is a portion on which the base of the building 1 in FIG. 3 is placed. The slab portion 29 is a portion corresponding to the vertical direction while forming a space B with the floor 8 of each room 6 in FIG. The notch 32 may be a through hole, but if it is an open notch 32 above, the middle part of the transport pipe 25 may be inserted into the notch 32 from above. Piping work of the transport pipe 25 is easier than a through hole that must be inserted. The through-hole 33 may be a notch that is open at the top, but if the through-hole 33 is an upper closed one, the heat storage material 26 around which the hard heat insulating material 27 around the through-hole 33 flows into the space. Works as a mold so as not to overflow the concrete, which is the material of the above, into the base portion 28. Since the heat storage body 26 is formed by interposing the hard heat insulating material 27 on the base 2 called a solid base, it is not affected by the moisture from the ground. Since the heat insulating material disposed between the heat storage body 26 and the slab portion 29 of the foundation 2 is the hard heat insulating material 27, when the concrete such as ready-mixed concrete which is the material of the heat storage body 26 is cast in place, the hard heat insulating material is used. 27 can support the wire mesh 30 and the transport pipe 25 at an appropriate position in the installation form with respect to the concrete cast in place. A spacer (not shown) is placed on the hard heat insulating material 27, and the wire mesh 30 is placed on the spacer, so that the wire mesh 30 and the transport pipe 25 are embedded in the heat storage body 26. Can be applied.
[0015]
The piping of the transport pipe 25 to each room 6 on the first floor in the building 1 will be described with reference to FIG. The transport pipe 25 penetrates from the discharge port 23 of the boiler 22 through the base portion 28 and the hard heat insulating material 27 (see FIG. 1) to the side corresponding to a certain room 6 from the outside, and corresponds to the one room 6. After the pipe is meandered at the portion where it is bent, it penetrates the base part 28 and the hard heat insulating material 27 at the boundary between the one room 6 and the next room 6 and corresponds to the next room 6. After being piped while meandering at the part, the next adjacent room is penetrated through the base portion 28 and the hard insulation material 27 at the boundary between the adjacent one room 6 and the further adjacent room 6. The pipes are meandering at the part corresponding to each room 6, and the base part 28 and the hard heat insulating material 27 are penetrated to the outside from the part corresponding to the last room 6. Then, it reaches the inlet 24 of the boiler 22. In a portion corresponding to each room 6, the transport pipe 25 is not connected to a portion for storing vegetables in the kitchen in order to prevent thermal deterioration of the vegetables. In addition, the transport pipe 25 is provided in a living room such as a living room or a dining room where a person walks, sits, and sleeps. The whole can be warmed at a uniform temperature. Therefore, the heat storage body 26 is entirely uniformly heated by the heat transmitted from the meandering transport pipe 25, and the heated heat storage body 26 is provided on the heat storage body 26 via the space B. The floor 8 of the room 6 on the first floor in the building 1 can be uniformly heated as a whole. In FIG. 2, reference numeral 34 denotes a dirt at the entrance, 35 denotes a toilet, 36 denotes a washroom, 37 denotes a bathroom, and 39 denotes a kitchen set.
[0016]
At the building site where the foundation 2 was made as described above, the installation of the hard heat insulating material 27, the installation of the wire mesh 30, the piping of the transport pipe 25, the binding by a binding wire (not shown), the casting of concrete such as ready-mixed concrete, etc. By performing the construction in order, the heat storage element 26 is formed on site, so that the heat storage element 26 should be provided with the heat storage element 26 of the base 2 as compared with the case where the heat storage element 26 produced in the factory is carried to the site and installed. Can be installed properly.
