Description

本発明は、潜熱蓄熱材を封入した容器が収容された潜熱蓄熱建材に関する。   The present invention relates to a latent heat storage building material in which a container enclosing a latent heat storage material is accommodated.

近年、需要の比較的少ない安価な深夜電力を利用できるという点で、省エネルギー性に優れた蓄熱式の暖房建材が注目されている。   In recent years, a heat storage type heating and building material excellent in energy saving has attracted attention because it can use inexpensive late-night power with relatively little demand.

この種の蓄熱式の暖房建材は、温度に応じて融解及び凝固を繰り返して蓄熱及び放熱を行う潜熱蓄熱材を利用したものであり、例えば特許文献１に開示されたものがある。   This type of heat storage type heating building material uses a latent heat storage material that stores heat and releases heat by repeatedly melting and solidifying depending on the temperature. For example, there is one disclosed in Patent Document 1.

特許文献１には、暖房床材として使用される建材であって、建材本体において蓄熱材容器を収容するための収容部を仕切り板によって区画することが提案されており、区画された空間には、シート状の蓄熱材を２枚の樹脂シートで挟んで該樹脂シートの周縁を熱融着によりシールし耳部とした蓄熱材容器が収容される。   Patent document 1 is a building material used as a heating floor material, and it is proposed that a storage portion for storing a heat storage material container in a building material main body is partitioned by a partition plate. Then, a sheet-like heat storage material is sandwiched between two resin sheets, and a heat storage material container having an ear portion by sealing the peripheral edge of the resin sheet by heat fusion is accommodated.

しかしながら、特許文献１の建材では、蓄熱材容器を収容するための区画された空間を該容器の耳部を見込んだ大きさにしなければならない。そうすると、耳部に対応する空間に蓄熱材が充填されず、蓄熱材の充填率が低下して蓄熱欠損が生じ、さらに、建材本体の強度が低下するという問題がある。   However, in the building material of Patent Document 1, the partitioned space for housing the heat storage material container must be sized to allow for the ears of the container. If it does so, the space corresponding to an ear | edge part is not filled with a heat storage material, the filling rate of a heat storage material falls, a heat storage defect | deletion arises, and also the intensity | strength of a building material main body falls.

本発明は斯かる諸点に鑑みてなされたものであり、その目的とするところは、建材本体に対する蓄熱材容器の収容構造に改良を加えることにより、蓄熱材の充填率を向上させ且つ建材本体の強度を確保することにある。   The present invention has been made in view of such various points. The object of the present invention is to improve the filling rate of the heat storage material by improving the housing structure of the heat storage material container with respect to the building material main body. It is to ensure strength.

上記の目的を達成するために、この発明では、建材本体に形成される容器収容部を建材本体の対向する両端部の一方から他方まで連続して延びる凹部とし、その途中に嵌込凹部を凹部の幅方向に対向するように凹陥し、嵌込凹部を凹部と同じ深さとし、該嵌込凹部に該嵌込凹部の深さよりも薄い仕切部材を嵌め込んで、該仕切部材と凹部の底面との間に隙間を設けることとした。   In order to achieve the above object, according to the present invention, the container housing portion formed in the building material main body is a recess extending continuously from one end to the other of the opposite opposing ends of the building material main body, and the fitting recess is a recess in the middle. The recessed portion is recessed so as to be opposed to the width direction, and the fitting recess has the same depth as the recess, and a partition member thinner than the depth of the fitting recess is fitted into the fitting recess, and the partition member and the bottom surface of the recess A gap was provided between the two.

具体的には、請求項１の発明は、裏面に容器収容部を有する建材本体と、該建材本体の容器収容部に収容され、温度に応じて融解及び凝固を繰り返して蓄熱及び放熱を行う潜熱蓄熱材が封入された複数の蓄熱材容器とを備えた潜熱蓄熱建材が対象である。   Specifically, the invention of claim 1 includes a building material main body having a container housing portion on the back surface, and a latent heat that is housed in the container housing portion of the building material main body and stores and releases heat by repeatedly melting and solidifying depending on the temperature. The target is a latent heat storage building material including a plurality of heat storage material containers in which a heat storage material is enclosed.

そして、上記容器収容部は、建材本体の対向する両端部の一方から他方まで連続して延びる凹部を有し、上記凹部は、上記建材本体の対向する両端面に到達せずに該両端面の手前に位置し又は該両端面に到達して開口し、上記凹部の長さ方向の中間部には、凹部の幅方向両側の建材本体をそれぞれ互いに対向するように凹陥してなる複数対の嵌込凹部が凹部長さ方向に所定間隔をあけて設けられ、該嵌込凹部は、深さが上記凹部と同じ深さに形成されており、上記嵌込凹部の深さよりも薄く形成され、かつ両端部が上記一対の嵌込凹部に嵌め込まれて上記凹部を仕切る仕切部材をさらに備え、上記各蓄熱材容器は、厚さが上記仕切部材と上記凹部の底面との間に形成された隙間よりも厚く、かつ厚さが該凹部の深さよりも薄くなるように形成されており、上記各蓄熱材容器の周縁部には上記潜熱蓄熱材を該蓄熱材容器内に封閉するための耳部が設けられており、該耳部が上記仕切部材と上記凹部の底面との間に形成された隙間に配置された状態で、該各蓄熱材容器が該仕切部材で仕切られた容器収容スペースに収容されていることを特徴とする。 And the said container accommodating part has a recessed part continuously extended from one side of the both ends which the building material main body opposes to the other, The said recessed part does not reach | attain both the opposing both end surfaces of the said building material main body, A plurality of pairs of fittings that are located in front or open to reach both end faces, and in which the building material main bodies on both sides in the width direction of the recess are recessed so as to face each other in the middle portion in the length direction of the recess. The recessed portion is provided at a predetermined interval in the length direction of the recessed portion, the recessed portion is formed to have the same depth as the recessed portion, and is formed thinner than the depth of the recessed portion, and The heat storage material container further includes a partition member having both ends fitted into the pair of insertion recesses to partition the recess, and the heat storage material container has a thickness formed between the partition member and the bottom surface of the recess. And the thickness is thinner than the depth of the recess. Are, in the peripheral portions of the respective heat storage material container and ear portion is provided for Fu閉the latent heat storage material heat accumulating material in the container, the ear portion and the bottom surface of the partition member and the recess Each heat storage material container is accommodated in the container accommodation space partitioned by the partition member in a state of being disposed in a gap formed between the two.

この請求項１の発明では、嵌込凹部の深さが凹部と同じ深さに形成され、この嵌込凹部に凹部の深さよりも薄い仕切部材の両端部が嵌め込まれた状態で、仕切部材と凹部の底面との間に隙間が形成されるので、この隙間に蓄熱材容器の一部（耳部）を配置することにより、凹部の仕切部材間全体に亘り潜熱蓄熱材を充填することができる。このように、凹部のほぼ全体に亘って潜熱蓄熱材を充填することができるので、潜熱蓄熱材の充填率が従来よりも向上し、蓄熱欠損を防ぐことができる。また、凹部のほぼ全体に亘って潜熱蓄熱材が充填されて空洞が生じないので、潜熱蓄熱建材の強度も確保することができる。 In the first aspect of the present invention, the depth of the recessed portion is formed to be the same depth as the recessed portion, and the partition member and the both ends of the partition member thinner than the depth of the recessed portion are fitted in the recessed portion, Since a gap is formed between the bottom surface of the recess, by arranging a part (ear portion) of the heat storage material container in the gap, the latent heat storage material can be filled over the entire partition member of the recess. . In this way, since the latent heat storage material can be filled over almost the entire recess, the filling rate of the latent heat storage material is improved as compared with the conventional case, and heat storage deficiency can be prevented. Moreover, since the latent heat storage material is filled over almost the entire recess and no cavity is formed, the strength of the latent heat storage building material can be ensured.

また、建材本体に蓄熱材容器を収容する際、仕切部材及び凹部に組み込まれた蓄熱材容器が建材本体に組み付けられた状態で、当該建材端部に設けられた実部を木槌等で叩いて隣り合う建材本体同士を実嵌合する。その際、仕切部材が建材本体凹部の幅方向に橋絡することによって建材本体の凹部対応箇所の強度が保持されるため、叩打による衝撃で建材本体が変形するのを防止することができる。   In addition, when housing the heat storage material container in the building material main body, the real part provided at the end of the building material is hit with a wooden mallet in the state where the heat storage material container incorporated in the partition member and the recess is assembled in the building material main body. The building material bodies adjacent to each other are actually fitted together. At that time, since the partition member bridges in the width direction of the building material main body concave portion, the strength of the portion corresponding to the concave portion of the building material main body is maintained, so that it is possible to prevent the building material main body from being deformed by an impact due to tapping.

さらに、仕切部材と凹部底面との間に位置する蓄熱材容器の一部（耳部）が仕切部材によって凹部底面側に押さえ付けられることで、蓄熱材容器が全体として該凹部底面に密着するので、潜熱蓄熱材の吸熱・放熱効率を向上させることができる。 Furthermore, since a part (ear part) of the heat storage material container positioned between the partition member and the bottom surface of the recess is pressed against the bottom surface of the recess by the partition member, the heat storage material container as a whole closely contacts the bottom surface of the recess. The heat absorption / heat radiation efficiency of the latent heat storage material can be improved.

さらにまた、仕切部材の側方に位置する蓄熱材容器が該仕切部材によってその移動を規制されるので、蓄熱材容器の位置ズレを防ぐことができる。その結果、建材本体で温度ムラが生じることはなく、均等な蓄熱効果が得られる。また、この建材を床材のように水平状態ではなく、壁材のように垂直状態に立てて施工しても、蓄熱材容器が落下することがない。   Furthermore, since the movement of the heat storage material container located on the side of the partition member is restricted by the partition member, it is possible to prevent the heat storage material container from being displaced. As a result, temperature unevenness does not occur in the building material body, and an even heat storage effect is obtained. Moreover, even if this building material is constructed in a vertical state such as a wall material rather than in a horizontal state like a flooring material, the heat storage material container does not fall.

さらにまた、耳部が仕切部材と凹部の底面との間の隙間に配置された状態で各蓄熱材容器が仕切部材の両側の容器収容スペースに収容されるので、潜熱蓄熱材が凹部に充填される。そのため、蓄熱欠損を防止しつつ、潜熱蓄熱建材の強度も確保することができる。また、蓄熱材容器の厚みが仕切部材と凹部底面との間に形成された隙間よりも厚いので、蓄熱材容器が仕切部材と凹部の底面とによって挟み込まれ、蓄熱材容器が凹部の底面に密着する。したがって、蓄熱材容器がさらに位置ズレせず、また、潜熱蓄熱材の吸熱及び放熱効率を向上させることができる。さらに、蓄熱材容器の厚さが凹部の深さよりも薄いので、蓄熱材容器が建材本体の裏面から突出するのを防ぐことができる。 Furthermore , since each heat storage material container is housed in the container housing space on both sides of the partition member in a state where the ear portion is disposed in the gap between the partition member and the bottom surface of the recess, the latent heat storage material is filled in the recess. The Therefore, the strength of the latent heat storage building material can be secured while preventing the heat storage deficiency. Further, since the thickness of the heat storage material container is thicker than the gap formed between the partition member and the bottom surface of the recess, the heat storage material container is sandwiched between the partition member and the bottom surface of the recess, and the heat storage material container is in close contact with the bottom surface of the recess. To do. Therefore, the heat storage material container is not further displaced, and the heat absorption and heat dissipation efficiency of the latent heat storage material can be improved. Furthermore, since the thickness of the heat storage material container is thinner than the depth of the recess, the heat storage material container can be prevented from protruding from the back surface of the building material main body.

請求項２の発明は、請求項１の発明において、上記嵌込凹部の長さ方向の端部は、上記建材本体の幅方向端面よりも中央側の位置にあり、該長さ方向の端部の両隅角部には、上記嵌込凹部内に向かって膨出する膨出部が形成され、上記仕切部材は、その両端部が上記隅角部の膨出部と圧接するように上記嵌込凹部に嵌め込まれていることを特徴とする。 According to a second aspect of the present invention, in the first aspect of the invention, the lengthwise end of the fitting recess is located at a position closer to the center than the widthwise end face of the building material body, and the lengthwise end. Both corners are formed with bulges that bulge into the fitting recesses, and the partition member is fitted with the fitting so that both ends thereof are in pressure contact with the bulges of the corners. It is characterized by being fitted in the recess.

この請求項２の発明では、嵌込凹部の長さ方向端部の両隅角部に膨出部が形成され、仕切部材はその両端部がこの膨出部に圧接するように当該嵌込凹部に嵌め込まれているので、この構造自体によって仕切部材が嵌込凹部から脱落するのを防止することができる。 According to the second aspect of the present invention, the bulging portion is formed at both corners of the lengthwise end of the fitting concave portion, and the fitting member has the fitting concave portion so that both ends thereof are in pressure contact with the bulging portion. Therefore, the structure itself can prevent the partition member from falling off the fitting recess.

以上説明したように、請求項１の発明によると、嵌込凹部の深さが凹部と同じ深さに形成され、この嵌込凹部に凹部の深さ寸法よりも薄い仕切部材の両端部が嵌め込まれた状態で、仕切部材と凹部の底面との間に隙間が形成されるので、この隙間に蓄熱材容器の一部（耳部）を配置することにより、凹部の仕切部材間全体に亘り潜熱蓄熱材を充填することができる。このように、凹部のほぼ全体に亘って潜熱蓄熱材を充填することができるので、潜熱蓄熱材の充填率が従来よりも向上し、蓄熱欠損を防ぐことができる。また、凹部のほぼ全体に亘って潜熱蓄熱材が充填されて空洞が生じないので、潜熱蓄熱建材の強度も確保することができる。また、仕切部材と凹部底面との間に位置する蓄熱材容器の一部（耳部）が仕切部材によって凹部底面側に押さえ付けられることで、蓄熱材容器が全体として該凹部底面に密着するので、潜熱蓄熱材の吸熱・放熱効率を向上させることができる。さらに、仕切部材の側方に位置する蓄熱材容器が該仕切部材によってその移動を規制されるので、蓄熱材容器の位置ズレを防ぐことができる。その結果、建材本体で温度ムラが生じることはなく、均等な蓄熱効果が得られる。また、この建材を床材のように水平状態ではなく、壁材のように垂直状態に立てて施工しても、蓄熱材容器が落下することがない。また、建材本体に蓄熱材容器を収容する際、仕切部材及び凹部に組み込まれた蓄熱材容器が建材本体に組み付けられた状態で、当該建材端部に設けられた実部を木槌等で叩いて隣り合う建材本体同士を実嵌合する。その際、仕切部材が建材本体凹部の幅方向に橋絡することによって建材本体の凹部対応箇所の強度が保持されるため、叩打による衝撃で建材本体が変形するのを防止することができる。 As described above, according to the first aspect of the present invention, the depth of the recessed portion is formed to be the same as that of the recessed portion, and both end portions of the partition member thinner than the depth dimension of the recessed portion are fitted into the recessed portion. In this state, a gap is formed between the partition member and the bottom surface of the recess. By placing a part (ear portion) of the heat storage material container in this gap, latent heat is generated across the entire partition member of the recess. A heat storage material can be filled. In this way, since the latent heat storage material can be filled over almost the entire recess, the filling rate of the latent heat storage material is improved as compared with the conventional case, and heat storage deficiency can be prevented. Moreover, since the latent heat storage material is filled over almost the entire recess and no cavity is formed, the strength of the latent heat storage building material can be ensured. Moreover, since a part (ear part) of the heat storage material container located between a partition member and a recessed part bottom face is pressed by the recessed part bottom side by a partition member, a heat storage material container adheres to this recessed part bottom face as a whole. The heat absorption / heat radiation efficiency of the latent heat storage material can be improved. Furthermore, since the movement of the heat storage material container located on the side of the partition member is restricted by the partition member, it is possible to prevent the heat storage material container from being displaced. As a result, temperature unevenness does not occur in the building material body, and an even heat storage effect is obtained. Moreover, even if this building material is constructed in a vertical state such as a wall material rather than in a horizontal state like a flooring material, the heat storage material container does not fall. In addition, when housing the heat storage material container in the building material main body, the real part provided at the end of the building material is hit with a wooden mallet in the state where the heat storage material container incorporated in the partition member and the recess is assembled in the building material main body. The building material bodies adjacent to each other are actually fitted together. At that time, since the partition member bridges in the width direction of the building material main body concave portion, the strength of the portion corresponding to the concave portion of the building material main body is maintained, so that it is possible to prevent the building material main body from being deformed by an impact due to tapping.

また、蓄熱材容器の厚みが仕切部材と凹部底面との間に形成された隙間よりも厚いので、蓄熱材容器が仕切部材と凹部の底面とによって挟み込まれ、蓄熱材容器が凹部の底面に密着する。したがって、蓄熱材容器がさらに位置ズレせず、また、潜熱蓄熱材の吸熱及び放熱効率を向上させることができる。さらに、蓄熱材容器の厚さが凹部の深さよりも薄いので、蓄熱材容器が建材本体の裏面から突出するのを防ぐことができる。 Further , since the thickness of the heat storage material container is thicker than the gap formed between the partition member and the bottom surface of the recess, the heat storage material container is sandwiched between the partition member and the bottom surface of the recess, and the heat storage material container is in close contact with the bottom surface of the recess. To do. Therefore, the heat storage material container is not further displaced, and the heat absorption and heat dissipation efficiency of the latent heat storage material can be improved. Furthermore, since the thickness of the heat storage material container is thinner than the depth of the recess, the heat storage material container can be prevented from protruding from the back surface of the building material main body.

請求項２の発明によると、嵌込凹部の長さ方向端部の両隅角部に膨出部が形成され、仕切部材はその両端部がこの膨出部に圧接するように当該嵌込凹部に嵌め込まれているので、この構造自体によって仕切部材が嵌込凹部から脱落するのを防止することができる。 According to the invention of claim 2 , the bulging portion is formed at both corners of the lengthwise end of the fitting concave portion, and the fitting member has the fitting concave portion so that both end portions thereof are pressed against the bulging portion. Therefore, the structure itself can prevent the partition member from falling off the fitting recess.

図４は潜熱蓄熱建材ＡのIV-IV線断面図である。上記各蓄熱材容器１０は、上記建材本体１の裏面１ａの上記容器収容部２に嵌合状態で収容可能な大きさの矩形薄板状のもので、例えばアルミニウム等の伝熱材料からなり、その内部には潜熱蓄熱材１１が封入されている。この蓄熱材容器１０の材料としては、充填する潜熱蓄熱材１１で溶解又は膨潤しないものを用いる必要があり（潜熱蓄熱材１１としてのパラフィンはオレフィン等を膨潤させる）、ＰＥＴ(Polyethylene terephthalate)及びポリエチレンの複合体にアルミニウムを蒸着したものや構成材料にアルミ箔を含むフィルム等、上記潜熱蓄熱材１１に対するバリヤ性を持つフィルムからなる袋状容器を用いることができる。上記蓄熱材容器１０の内部に上記潜熱蓄熱材１１が封入されているので、該蓄熱材容器１０の周縁部には、上記潜熱蓄熱材１１の漏出を防止すべく、耳部１０ａ（シール部）が設けられている。   FIG. 4 is a cross-sectional view of the latent heat storage building material A, taken along the line IV-IV. Each said heat storage material container 10 is a rectangular thin-plate-shaped thing of the magnitude | size which can be accommodated in the said container accommodating part 2 of the back surface 1a of the said building material main body 1, for example, consists of heat-transfer materials, such as aluminum, The latent heat storage material 11 is enclosed inside. As the material of the heat storage material container 10, it is necessary to use a latent heat storage material 11 to be filled that does not dissolve or swell (paraffin as the latent heat storage material 11 swells olefin or the like), PET (Polyethylene terephthalate) and polyethylene It is possible to use a bag-like container made of a film having barrier properties against the latent heat storage material 11, such as a film obtained by vapor-depositing aluminum on the composite or a film containing aluminum foil as a constituent material. Since the latent heat storage material 11 is sealed inside the heat storage material container 10, the peripheral portion of the heat storage material container 10 has an ear portion 10 a (seal portion) to prevent leakage of the latent heat storage material 11.

Therefore, the heat storage material containers 10, 10,... Are not further displaced, and the heat absorption and heat dissipation efficiency of the latent heat storage materials 11, 11,. Further, since the heat storage material containers 10, 10,... Are thinner than the depth dimension a of the recess 3, the heat storage material containers 10, 10,...

FIG. 7: is a top view which shows a part of building material main body 1 of the latent heat storage building material A which concerns on the modification 1 of embodiment of this invention. In the building material body 1 of this modification, bulging portions 4b and 4b bulging toward the fitting recess 4 are formed at the corners of the lengthwise ends of the fitting recesses 4, 4,. And the said partition member 12 is engage | inserted by each said fitting recess 4,4 ... so that the both ends may press-contact the said corner | angular part 4b, 4b, .... Therefore, it is possible to prevent the partition members 12, 12,... From dropping from the fitting recesses 4, 4,. Therefore, it is not necessary to bond the partition members 12, 12,... To the respective fitting recesses 4, 4,.

《発明の実施形態の変形例２》
図８は、本発明の実施形態の変形例２に係る潜熱蓄熱建材Ａの分解斜視図である。本変形例の潜熱蓄熱建材Ａの建材本体１では、凹部３の長さ方向端部が該建材本体１の長さ方向端面１ｂに到達して開口し、さらに、嵌込凹部４の長さ方向の端部が該建材本体１の幅方向端面１ｃに到達して開口している。 << Modification 2 of Embodiment of Invention >>
FIG. 8 is an exploded perspective view of the latent heat storage building material A according to Modification 2 of the embodiment of the present invention. In the building material main body 1 of the latent heat storage building material A of the present modified example, the lengthwise end of the recess 3 reaches and opens the lengthwise end surface 1b of the building material main body 1, and further, the length direction of the fitting recess 4 The end portion of the building material reaches the width direction end surface 1c of the building material main body 1 and opens.

このような建材本体１を製造する際には、まず、未加工の建材本体１の裏面１ａにおいて、その建材本体１の幅方向の中央位置に、長さ方向に対向する一端部から他端部まで連続する溝部７を、たとえばプレーナ等を用いて、大まかに加工する。   When manufacturing such a building material main body 1, first, on the rear surface 1 a of the unprocessed building material main body 1, the other end portion from one end facing the length direction to the center position in the width direction of the building material main body 1. For example, a planar portion or the like is roughly processed using the planar portion 7.

次いで、上記溝部７においてその長さ方向に所定間隔をあけた複数（６つ）の部位を、溝部７の加工と同じくプレーナ等を用いて、該溝部７の幅方向に対向する一端部から他端部まで連続する一対の嵌込凹部４，４を加工する。   Next, a plurality of (six) portions at predetermined intervals in the length direction of the groove portion 7 are separated from one end portion facing the width direction of the groove portion 7 by using a planar or the like in the same manner as the processing of the groove portion 7. A pair of insertion recessed parts 4 and 4 which continue to an edge part are processed.

このように、各対の嵌込凹部４，４をプレーナ等で切削加工することができるので、図１に示す実施形態に比べて加工速度を向上させることができる。   Thus, since each pair of insertion recessed parts 4 and 4 can be cut with a planar etc., a processing speed can be improved compared with embodiment shown in FIG.

《発明の実施形態の変形例３》
図９は、本発明の実施形態の変形例３に係る潜熱蓄熱建材Ａを示す分解斜視図である。本変形例の潜熱蓄熱建材Ａの建材本体１では、上記変形例２と同様に、凹部３の長さ方向端部が該建材本体１の長さ方向端面１ｂに到達して開口し、また、嵌込凹部４の長さ方向の端部が該建材本体１の幅方向端面１ｃに到達して開口している。さらに、凹部３の長さ方向両端にも、それぞれ一対の嵌込凹部４が凹設され、各一対の嵌込凹部４，４に仕切部材１２の両端が嵌め込まれている。 << Modification 3 of Embodiment of Invention >>
FIG. 9 is an exploded perspective view showing a latent heat storage building material A according to Modification 3 of the embodiment of the present invention. In the building material main body 1 of the latent heat storage building material A of the present modification, the lengthwise end of the recess 3 reaches the lengthwise end surface 1b of the building material main body 1 and opens, as in the second modification. The end of the fitting recess 4 in the length direction reaches the width direction end face 1c of the building material main body 1 and opens. Further, a pair of fitting recesses 4 are respectively provided at both ends of the recess 3 in the length direction, and both ends of the partition member 12 are fitted into the pair of fitting recesses 4, 4.

このように、凹部３が建材本体１の長さ方向端面１ｂに到達して開口しているので、上記変形例１と同様に、建材本体１の裏面１ａ側からプレーナ等によって切削加工することにより、該凹部３を簡単に形成することができるものの、建材本体１の長さ方向端部の強度が比較的低くなる。しかし、当該長さ方向両端にそれぞれ一対の嵌込凹部４，４を凹設し、そこに仕切部材１２を架設しているので、建材本体１の長さ方向両端の強度を保つことができる。   Thus, since the recessed part 3 reaches | attains and opens the length direction end surface 1b of the building material main body 1, it cuts with the planar etc. from the back surface 1a side of the building material main body 1 similarly to the said modification 1. Although the concave portion 3 can be easily formed, the strength of the end portion in the length direction of the building material main body 1 is relatively low. However, since the pair of fitting recesses 4 and 4 are respectively provided at both ends in the length direction and the partition member 12 is installed there, the strength at both ends in the length direction of the building material main body 1 can be maintained.

《その他の実施形態》
上記実施形態の説明では、容器収容部２として、建材本体１の裏面に長さ方向に延びる１列の凹部３を有するものとし、その凹部３に嵌込凹部４，４，…を形成しているが、図１１に示すように、建材本体１の裏面に長さ方向に延びる２列の凹部３，３を有するものとし、その各凹部３に嵌込凹部４，４，…を形成してもよく、さらには凹部３の列を３列以上に増やしてもよい。 << Other Embodiments >>
In the description of the above embodiment, the container housing portion 2 has a row of recesses 3 extending in the length direction on the back surface of the building material main body 1, and fitting recesses 4, 4,. However, as shown in FIG. 11, the rear surface of the building material body 1 has two rows of recesses 3, 3 extending in the length direction, and the recesses 3, 4,. Further, the number of the recesses 3 may be increased to three or more.

《参考形態》《Reference form》
尚、上記実施形態の説明では、蓄熱材容器１０として、仕切部材１２同士の間に形成された容器収容スペース５に収容可能な大きさのものとしたが、図１０に示すように、凹部３の長さ方向全体に亘って収容される容器１３としてもよい。この蓄熱材容器１３は、平面視で上記凹部３と同じ矩形状をなし、上記隙間Ｓに対応する部分がシールされ、このシール部分のみが上記隙間Ｓの寸法よりも僅かに厚くなっている。このように、隙間Ｓの寸法よりも厚くすることにより、該蓄熱材容器１３が部分的に仕切部材１２と凹部３の底面３ａとによって挟み込まれるので、該蓄熱材容器１３が容器収容部２から脱落するのを防止することができる。In the description of the above embodiment, the heat storage material container 10 has a size that can be accommodated in the container accommodation space 5 formed between the partition members 12. However, as shown in FIG. It is good also as the container 13 accommodated over the whole length direction. The heat storage material container 13 has the same rectangular shape as the concave portion 3 in plan view, and a portion corresponding to the gap S is sealed, and only this sealed portion is slightly thicker than the size of the gap S. Thus, by making it thicker than the dimension of the gap S, the heat storage material container 13 is partially sandwiched between the partition member 12 and the bottom surface 3a of the recess 3, so that the heat storage material container 13 is removed from the container housing portion 2. It can be prevented from falling off.

本発明は、仕切部材と容器収容部の凹部底面との間に形成された隙間に蓄熱材容器の一部（耳部）を配設するように該容器収容部に蓄熱材容器を収容し、容器収容部に対する潜熱蓄熱材の充填率を確保するとともに建材本体の強度も確保するので、極めて有用であり、産業上の利用可能性が高い。 The present invention accommodates the heat storage material container in the container housing portion so as to dispose a part (ear portion) of the heat storage material container in the gap formed between the partition member and the bottom surface of the recess of the container housing portion, Since the filling rate of the latent heat storage material in the container housing portion is ensured and the strength of the building material main body is also ensured, it is extremely useful and has high industrial applicability.
