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及びその製造方法に関する。   The present invention relates to a latent heat storage building material in which a container enclosing a latent heat storage material is accommodated, and a method for manufacturing the same.

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、従来、例えば特許文献１に示されるように、潜熱蓄熱材を容器内に封入し、その容器を建材本体の空洞内に収容した薄型の蓄熱式暖房建材（床材）が知られている。   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. Conventionally, for example, as shown in Patent Document 1, a latent heat storage material is used. A thin heat storage heating building material (floor material) is known in which a container is enclosed in a cavity of a building material body.

一方、特許文献２には、同様に暖房床材として使用される建材であるが、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いる。   On the other hand, Patent Document 2 proposes a building material used as a heating floor material in the same manner. However, it is proposed that a housing portion for housing a heat storage material container in a building material body is partitioned by a partition plate.

特開２０００−２８３４８１号公報Japanese Patent Laid-Open No. 2000-283482 特開２０００−２８１５４号公報JP 2000-28154 A

しかし、特許文献１に示されるものでは、建材本体の空洞内で蓄熱材の容器が位置ずれすることがあり、このずれに起因してパネルに温度むらが生じる虞れがある。この建材は床材として利用されているが、仮に暖房用の壁材として立てた状態で施工すると、蓄熱材容器が当初の位置から落下することとなり、蓄熱効果を全く発揮することができなくなる。   However, in the one shown in Patent Document 1, the container of the heat storage material may be displaced within the cavity of the building material main body, and there is a possibility that temperature unevenness may occur in the panel due to this displacement. Although this building material is used as a flooring, if it is constructed in a state where it is stood as a wall material for heating, the heat storage material container falls from the initial position, and the heat storage effect cannot be exhibited at all.

これに対し、上記特許文献２のものでは、容器収容部に収容された蓄熱材容器が位置ずれするのを仕切り板で防ぐことができ、パネルの温度むらが発生するのを防止することができる。また、壁材等として立てて使用しても、蓄熱材容器は仕切り板で支持されるので、落下することはない。   On the other hand, in the thing of the said patent document 2, it can prevent that the thermal storage material container accommodated in the container accommodating part is displaced by a partition plate, and can prevent that the temperature nonuniformity of a panel generate | occur | produces. . Moreover, even if it stands up and uses as a wall material etc., since the thermal storage material container is supported by the partition plate, it does not fall.

ところが、その反面、建材本体とは別途に複数の仕切り板を作製し、それを収容部内に接着固定する作業が必要となり、生産性が低下してコストアップするという問題が生じる。そればかりでなく、仕切り板の接着が外れる可能性もあり、信頼性が低い。   However, on the other hand, it is necessary to prepare a plurality of partition plates separately from the building material main body, and to bond and fix them in the housing portion, resulting in a problem that productivity is reduced and costs are increased. In addition, there is a possibility that the partition plate may come off and the reliability is low.

尚、建材本体に、蓄熱材容器を収容するための容器収容部を該各蓄熱材容器に対応して個別に複数形成するようにしてもよいが、それらの複数の容器収容部を１つずつルータ等で切削する必要があり、加工時間が長くなって、やはり生産性の低下によりコストアップするのは避けられない。   In addition, although you may make it form in the building material main body the container accommodating part for accommodating a thermal storage material container separately corresponding to each said thermal storage material container, those several container accommodating parts are carried out one by one It is necessary to cut with a router or the like, the processing time becomes long, and it is inevitable that the cost is increased due to a decrease in productivity.

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、蓄熱材容器の位置ずれを確実に防止するとともに、その構造を高い生産性で実現できるようにすることにある。   The present invention has been made in view of such various points, and the object of the present invention is to reliably prevent the position of the heat storage material container from being shifted by improving the housing structure of the heat storage material container with respect to the building material main body. The purpose is to realize the structure with high productivity.

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、その途中にずれ規制凸部を凹部の幅方向に対向するように一体に突設することとした。   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 concave portion that continuously extends from one end to the other of the opposing opposite ends of the building material main body, and a displacement regulating convex portion is provided in the middle thereof. It was decided to project integrally so as to face the width direction of the recess.

具体的には、請求項１の発明は、片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 one side, and a latent heat that is stored 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するものとする。また、この凹部の長さ方向の中間部には、凹部の幅方向両側面からそれぞれ中央側に互いに間隔をあけて対向するように突出する少なくとも１対のずれ規制凸部が一体に設けられており、これらの両ずれ規制凸部両側の凹部に蓄熱材容器が収容されていることを特徴とする。   And the said container accommodating part shall have a recessed part extended continuously from one side of the both ends which a building material main body opposes to the other. In addition, at least one pair of displacement restricting protrusions that protrude from the both sides in the width direction of the recess to the center side from the both sides in the width direction are integrally provided at the intermediate portion in the length direction of the recess. And the thermal storage material container is accommodated in the recessed part of both sides of these both deviation control convex parts.

この請求項１の発明では、建材本体の片面に、複数の蓄熱材容器を収容する容器収容部が形成され、この容器収容部は、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、この凹部の途中に、対とされたずれ規制凸部が凹部幅方向に対向するように一体に突設されており、凹部においてずれ規制凸部を除いた複数のスペースにそれぞれ蓄熱材容器が収容される。そのため、その各蓄熱材容器が凹部の長さ方向に位置ずれしようとしても、対となった両ずれ規制凸部によって規制されることとなり、蓄熱材容器の位置ずれによって建材本体で温度むらが生じることはない。また、この建材を床材のように水平状態ではなくて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はない。   In this invention of Claim 1, the container accommodating part which accommodates a some heat storage material container is formed in the single side | surface of a building material main body, and this container accommodating part continues from one side of the both ends which a building material main body opposes to the other. In the middle of the concave portion, a pair of shift regulation convex portions are integrally projected so as to face the concave portion width direction, and in the concave portions, a plurality of spaces excluding the shift regulation convex portions are provided. Each heat storage material container is accommodated. Therefore, even if each of the heat storage material containers tries to be displaced in the length direction of the concave portion, it will be regulated by the paired deviation regulating convex portions, and the temperature unevenness occurs in the building material main body due to the positional deviation of the heat storage material container. There is nothing. Further, even when the building material is constructed in a vertical state such as a wall material instead of a horizontal state like a flooring material, the heat storage material container does not fall.

また、容器収容部は、建材本体の凹部の長さ方向の途中にずれ規制凸部が一体に突設されたものであるので、従来のように仕切り板を接着する作業が不要であり、その接着不良により仕切り板が外れる虞れもなく、蓄熱材容器の位置ずれを確実に防止して信頼性を高めることができるとともに、その構造を高い生産性で実現してコストダウンを図ることができる。   In addition, since the container accommodating portion is integrally formed with the shift regulating convex portion in the middle of the length direction of the concave portion of the building material main body, there is no need for the work of bonding the partition plate as in the prior art. There is no risk of the partition plate coming off due to poor adhesion, and it is possible to reliably prevent the displacement of the heat storage material container and improve the reliability, and realize the structure with high productivity to reduce the cost. .

さらに、凹部において互いに間隔をあけて対向する両ずれ規制凸部間に蓄熱材容器のないスペースが生じており、このスペースによって以下の作用効果が得られる。すなわち、蓄熱材容器に封入されている潜熱蓄熱材は固定及び液体の相変化により熱の出入りが生じるものであるが、その際に体積も変化し、液体から固体になると体積が減少し、逆に固体から液体に変化すると体積が増大する。可能な限り潜熱蓄熱材の容量を増やして蓄熱効果を上げるために、容器収容部での蓄熱材容器のスペースを潜熱蓄熱材が固体状態にあるときの大きさに合わせた場合、液相状態に変化した際に、その体積の増加分だけスペースが不足することとなり、蓄熱材容器が容器収容部からはみ出すこととなる。しかし、この発明では、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、その凹部内で対向する両ずれ規制凸部間に開放スペースが形成されているので、潜熱蓄熱材が液相状態に変化して容器の体積が増大した際に、このスペースが蓄熱材容器の膨張を吸収する空間となり、そのスペースによって膨張分が吸収される。よって、可能な限り潜熱蓄熱材の容量を増やして蓄熱効果を上げながらも、その膨張時の容器のはみ出しを防止することができる。   Furthermore, a space without the heat storage material container is generated between the both-side deviation regulating convex portions facing each other with a gap in the concave portion, and the following effects can be obtained by this space. In other words, the latent heat storage material enclosed in the heat storage material container generates heat in and out due to the phase change of the liquid and the liquid, but the volume also changes at that time. When changing from solid to liquid, the volume increases. In order to increase the capacity of the latent heat storage material as much as possible to increase the heat storage effect, if the space of the heat storage material container in the container housing is adjusted to the size when the latent heat storage material is in the solid state, it will be in the liquid phase state When it changes, space will run short by the increase in the volume, and a thermal storage material container will protrude from a container accommodating part. However, in this invention, the container housing portion has a recess that continuously extends from one end to the other of the opposing opposite ends of the building material main body, and an open space is formed between the opposite displacement restricting protrusions in the recess. Therefore, when the latent heat storage material changes to a liquid phase and the volume of the container increases, this space becomes a space that absorbs the expansion of the heat storage material container, and the expansion is absorbed by the space. Therefore, while increasing the capacity of the latent heat storage material as much as possible to increase the heat storage effect, it is possible to prevent the container from protruding during the expansion.

さらに、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の途中に両ずれ規制凸部が一体に突設されているので、これらのずれ規制凸部によって建材本体の強度を確保することができ、ずれ規制凸部が全くなくて凹部のみの場合のように、その直線状凹部の幅方向両端が折り目となるように幅方向に変形して反りや破壊が生じるのを防止することができる。また、容器収容部の凹部において両ずれ規制凸部により幅の狭い部分が形成されるので、上記変形が抑えられる。   In addition, since the deviation-regulating protrusions are integrally projected in the middle of the recess that continuously extends from one to the other of the opposite ends of the building material body, the strength of the building material body is secured by these deviation-regulating protrusions. As in the case where there is no deviation regulating convex part and there is only a concave part, it is possible to prevent warping and breakage due to deformation in the width direction so that both ends in the width direction of the linear concave part become creases. be able to. In addition, since the narrow portion is formed by the deviation-regulating convex portion in the concave portion of the container housing portion, the above deformation can be suppressed.

請求項２の発明は、請求項１の発明において、上記容器収容部の凹部の底面と側面との境界角部、及び凹部の底面とずれ規制凸部の側面との境界角部は、外側に膨出する断面円弧形状であ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 boundary corner portion between the bottom surface and the side surface of the concave portion of the container housing portion, and the boundary corner portion between the bottom surface of the concave portion and the side surface of the displacement regulating convex portion are outward. It is characterized by a bulging cross-sectional arc shape.

この請求項２の発明では、容器収容部の凹部の底面と側面との境界角部、及び凹部の底面とずれ規制凸部の側面との境界角部が断面円弧形状であるので、建材を例えば容器収容部が裏面（下面）となるようにして床材として使用したときに、その表面（上面）から荷重が加わっても、その凹部の底面と側面との境界角部、及び凹部の底面とずれ規制凸部の側面との境界角部に応力が集中するのを回避することができ、同境界角部からの破壊を防止することができる。   In the invention of claim 2, since the boundary corner between the bottom surface and the side surface of the concave portion of the container housing portion and the boundary corner portion between the bottom surface of the concave portion and the side surface of the displacement regulating convex portion are in a circular arc shape, Even when a load is applied from the front surface (upper surface) when the container housing portion is used as a floor material with the back surface (lower surface), the boundary corner between the bottom surface and the side surface of the recess, and the bottom surface of the recess It is possible to avoid stress concentration at the boundary corner portion with the side surface of the shift regulating convex portion, and to prevent breakage from the boundary corner portion.

また、上記境界角部が断面直角形状である場合に比べ、容器の角が丸いときや、形状が変化する袋状容器のときは、蓄熱部材の容器が境界角部にスムーズに密着して隙間がなくなるので、その蓄熱部材の容器自体を補強材として機能させることができるとともに、蓄熱部材の容器と建材本体との接触面積が増大して蓄熱効果、吸放熱効果が高くなる。   In addition, when the corner of the container is round or when the shape of the bag is changed, the container of the heat storage member is smoothly and closely adhered to the boundary corner as compared with the case where the boundary corner has a right-angle cross section. Therefore, the container itself of the heat storage member can be made to function as a reinforcing material, and the contact area between the container of the heat storage member and the building material main body is increased, so that the heat storage effect and the heat absorption / release effect are enhanced.

請求項３の発明は、片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を製造する方法として、上記建材本体に容器収容部を形成するとき、該建材本体の対向する端部の一方から他方まで連続する溝部を切削する。次いで、上記溝部においてその長さ方向に所定間隔をあけた部位を該部位間に一定の残部を残してルータ加工により幅方向両側に拡張し、このことで、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、該凹部の長さ方向の中間部に、凹部の幅方向両側面からそれぞれ中央側に互いに間隔をあけて対向するように突出する少なくとも１対のずれ規制凸部とを有する容器収容部を形成することを特徴とする。   The invention of claim 3 includes a building material main body having a container housing part on one side, and a latent heat storage material that is stored in the container housing part of the building material main body and repeatedly stores and heats according to temperature to store and release heat. As a method of manufacturing a latent heat storage building material provided with a plurality of heat storage material containers, when forming a container housing portion in the building material main body, a continuous groove from one end to the other of the opposite ends of the building material main body is cut. . Next, a part of the groove having a predetermined interval in the length direction is expanded to both sides in the width direction by router processing leaving a certain remaining part between the parts. A recess extending continuously from the other to the other, and at least one pair of displacement regulating protrusions projecting so as to be opposed to each other from the both sides in the width direction of the recess toward the center side in the middle in the length direction of the recess. And a container housing portion having a portion.

この請求項３の発明では、建材本体の対向する端部の一方から他方まで連続する溝部が例えばプレーナ等で切削される。その後、この溝部において所定間隔をあけた部位が幅方向両側に拡張するようにルータにより加工され、凹部と、その長さ方向の中間部に互いに対向するように突出するずれ規制凸部とを有する容器収容部が形成される。このようにプレーナ等で大まかに溝部を切削した後に、その溝部の幅を部分的に拡大するようにルータで加工するので、ずれ規制凸部が一体に形成された容器収容部であっても、加工時間を大幅に短縮することができ、上記の潜熱蓄熱建材を容易に製造することができる。   In this invention of Claim 3, the groove part which continues from one side of the edge part which the building material main body opposes to the other is cut | disconnected by a planar etc., for example. After that, the groove portion is processed by the router so as to extend at a predetermined interval on both sides in the width direction, and has a concave portion and a shift regulating convex portion that projects so as to face each other in the middle portion in the length direction. A container housing portion is formed. After roughly cutting the groove part with a planar or the like in this way, since it is processed with a router so as to partially expand the width of the groove part, even if it is a container housing part integrally formed with a deviation regulating convex part, The processing time can be greatly shortened, and the latent heat storage building material can be easily manufactured.

以上説明したように、請求項１の発明によると、建材本体片面の容器収容部に複数の蓄熱材容器が収容された潜熱蓄熱建材において、容器収容部を、建材本体の対向両端部の一方から他方まで連続して延びる凹部を有するものとし、この凹部の長さ方向の中間部に、凹部の幅方向両側面から中央側に互いに間隔をあけて突出するずれ規制凸部を一体に設け、両ずれ規制凸部両側の凹部に蓄熱材容器を収容するようにしたことにより、各蓄熱材容器が凹部の長さ方向に位置ずれするのを両ずれ規制凸部によって規制し、蓄熱材容器の位置ずれによる温度むらや、縦置きの施工状態での蓄熱材容器の落下を防止して、信頼性を高めることができるとともに、その構造を高い生産性で実現してコストダウンを図ることができる。また、潜熱蓄熱材が液相状態に変化して容器の体積が増大した際に、両ずれ規制凸部間の開放スペースで蓄熱材容器の膨張を吸収して、可能な限り潜熱蓄熱材の容量を増やして蓄熱効果を上げながら、その膨張時の容器のはみ出しを防止することができる。さらに、凹部の途中の両ずれ規制凸部によって建材本体の強度を確保することができる。   As explained above, according to the invention of claim 1, in the latent heat storage building material in which a plurality of heat storage material containers are stored in the container storage portion on one side of the building material main body, the container storage portion is separated from one of the opposing opposite ends of the building material main body. It is assumed that the concave portion continuously extending to the other side is provided, and at the intermediate portion in the length direction of the concave portion, a displacement regulating convex portion that protrudes from the both sides in the width direction of the concave portion to the center side is provided integrally. Since the heat storage material containers are accommodated in the recesses on both sides of the deviation regulating convex part, the positional deviation of each heat storage material container in the length direction of the concave part is regulated by the both deviation regulating convex parts. It is possible to prevent temperature unevenness due to misalignment and fall of the heat storage material container in a vertically installed construction state, thereby improving the reliability and realizing the structure with high productivity to reduce the cost. In addition, when the latent heat storage material changes to a liquid phase and the volume of the container increases, the expansion of the heat storage material container is absorbed in the open space between the deviation regulating projections, and the capacity of the latent heat storage material is as much as possible. While increasing the heat storage effect, it is possible to prevent the container from protruding during its expansion. Furthermore, the strength of the building material main body can be ensured by the deviation-regulating convex portion in the middle of the concave portion.

請求項２の発明によると、容器収容部の凹部の底面と側面との境界角部、及び凹部の底面とずれ規制凸部の側面との境界角部を断面円弧形状としたことにより、建材の表面からの荷重による境界角部への応力集中を回避して同境界角部からの破壊を防止することができるとともに、蓄熱部材の容器を境界角部にスムーズに隙間なく密着させて、蓄熱部材の容器自体を補強材として機能させることができ、さらには蓄熱部材の容器と建材本体との接触面積を増大させて蓄熱効果、吸放熱効果を高めることができる。   According to the invention of claim 2, the boundary corner portion between the bottom surface and the side surface of the concave portion of the container housing portion and the boundary corner portion between the bottom surface of the concave portion and the side surface of the displacement restricting convex portion are formed into a circular arc shape in cross section. While avoiding stress concentration at the boundary corner due to the load from the surface and preventing breakage from the boundary corner, the heat storage member is smoothly and closely adhered to the boundary corner without any gap. The container itself can function as a reinforcing material, and further, the contact area between the container of the heat storage member and the building material main body can be increased to enhance the heat storage effect and the heat absorbing / dissipating effect.

請求項３の発明によると、上記潜熱蓄熱建材を製造する方法として、建材本体の対向する端部の一方から他方まで連続する溝部を切削した後、その溝部の長さ方向に所定間隔をあけた部位をルータ加工により幅方向両側に拡張することにより、建材本体にプレーナ等で大まかに溝部を切削した後に、その溝部の幅を部分的に拡大するようにルータで加工でき、ずれ規制凸部が一体に形成された容器収容部であっても、加工時間を大幅に短縮することができる。   According to the invention of claim 3, as a method of manufacturing the latent heat storage building material, after cutting a continuous groove from one end to the other of the opposite ends of the building material main body, a predetermined interval is provided in the length direction of the groove. By extending the part to both sides in the width direction by router processing, after cutting the groove part roughly with a planar etc. in the building material main body, it can be processed with the router so that the width of the groove part is partially expanded, and the deviation regulating convex part Even in the case of an integrally formed container accommodating portion, the processing time can be greatly reduced.

FIG. 1 shows a latent heat storage building material A according to an embodiment of the present invention, and this latent heat storage building material A is used as a floor material (latent heat storage floor material), for example. The latent heat storage building material A is integrally joined to the plate-like building material main body 1 made of a wood material (for example, MDF) or the like, and the building material main body 1 in the same manner as a normal flooring material or wall material. And a lid 14 (backer) made of a thin plate. The building material main body 1 is made of, for example, a plate material having a width of 303 mm and a length of 1820 mm. On one side (rear surface) of the building material main body 1, a concave groove-shaped container housing portion 2 is formed. However, some of the heat storage material containers 10, 10,... Are accommodated. And the said heat | fever storage material container 10,10, ... is accommodated in the container accommodating part 2, and the said cover material 14 is joined to the back surface of the building material main body 1 so that the opening of the container accommodating part 2 may be closed.

上記各蓄熱材容器１０は、建材本体１裏面の容器収容部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（図５参照）が封入されている。この蓄熱材容器１０の材料としては、アルミニウムの他に例えばポリエチレンやポリオレフィン、ＰＥＴ、ＡＢＳ等を用いることができるが、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る（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）。また、ＰＥＴ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、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。また、蓄熱材容器１０が袋状の場合は、その内部に潜熱蓄熱材１１が封入されているので、蓄熱材容器１０周囲の各角部１０ａは断面円弧形状に膨出している（図５参照）。   Each said heat storage material container 10 is a rectangular thin-plate-shaped thing of the magnitude | size which can be accommodated in the container accommodating part 2 of building material main body 1 back surface, for example, consists of heat-transfer materials, such as aluminum, and latent heat is contained in the inside. A heat storage material 11 (see FIG. 5) is enclosed. As the material of the heat storage material container 10, for example, polyethylene, polyolefin, PET, ABS or the like can be used in addition to aluminum, but it is necessary to use a material that does not dissolve or swell in the latent heat storage material 11 to be filled (latent heat storage Paraffin as the material 11 swells olefin and the like). Moreover, the bag-shaped container which consists of a film which has barrier property with respect to the latent heat storage material 11, such as what vapor-deposited aluminum on the composite of PET and polyethylene, and the film which contains aluminum foil in a constituent material can be used. Moreover, when the heat storage material container 10 is bag-shaped, since the latent heat storage material 11 is enclosed therein, each corner | angular part 10a around the heat storage material container 10 swells in cross-sectional arc shape (refer FIG. 5). ).

上記潜熱蓄熱材１１は、温度に応じて融解及び凝固を繰り返して蓄熱と放熱を行うもので、融点よりも低い温度で固体となり、融点以上の温度で液体となる。潜熱蓄熱材１１としては、例えばｎ−オクタデカン、ｎ−ヘキサデカンが主原料のノルマルパラフィンが用いられる。このノルマルパラフィンは、融点が２３〜２８℃のもので、基本的に融点よりも低い温度で固体となり、融点以上の高い温度で液体となる。この潜熱蓄熱材１１としてのノルマルパラフィンは略そのままアルミニウム等の容器１０に封入されて使用され、温度変化に応じて固体・液体と相変化する。ノルマルパラフィンの比重は約０．８である。   The latent heat storage material 11 performs heat storage and heat dissipation by repeatedly melting and solidifying depending on the temperature, becomes solid at a temperature lower than the melting point, and becomes liquid at a temperature higher than the melting point. As the latent heat storage material 11, for example, normal paraffin whose main raw material is n-octadecane or n-hexadecane is used. This normal paraffin has a melting point of 23 to 28 ° C., basically becomes a solid at a temperature lower than the melting point, and becomes a liquid at a temperature higher than the melting point. The normal paraffin as the latent heat storage material 11 is used by being enclosed in a container 10 made of aluminum or the like as it is, and changes in phase with a solid / liquid according to a temperature change. The specific gravity of normal paraffin is about 0.8.

ノルマルパラフィン以外の潜熱蓄熱材１１としては、無機水和塩（塩化カルシウム六水和塩、硫酸ナトリウム十水和塩等）、脂肪酸類（パルミチン酸、ミリスチン酸等）、芳香族炭化水素化合物（ベンゼン、ｐ−キシレン等）、エステル化合物（パルミチン酸イソプロピル、ステアリン酸ブチル等）、アルコール類（ステアリルアルコール等）、ポリアルキレングリコール等を使用することができる。   As the latent heat storage material 11 other than normal paraffin, inorganic hydrate salts (calcium chloride hexahydrate, sodium sulfate decahydrate, etc.), fatty acids (palmitic acid, myristic acid, etc.), aromatic hydrocarbon compounds (benzene) , P-xylene, etc.), ester compounds (isopropyl palmitate, butyl stearate, etc.), alcohols (stearyl alcohol, etc.), polyalkylene glycols, and the like can be used.

このような潜熱蓄熱材１１が蓄熱材容器１０内に封入され、その複数の蓄熱材容器１０，１０，…が建材本体１の容器収容部２に収容されている潜熱蓄熱建材Ａでは、例えば室内の床部において床下地材上に施工されたとき、上記潜熱蓄熱材１１の蓄熱効果により床面ないし室内の温度を一定に保つ恒温効果が得られる。例えば床暖房時（床冷房時）に電気ヒータや温水パイプ（冷水パイプ）による加温状態（冷温状態）を停止したときにも、その後、蓄熱材１１の蓄熱効果により恒温効果が得られる。また、室内床面に日射があって床面が加温されていると、その熱を潜熱蓄熱材１１に蓄熱し、その後に日射が途絶えても潜熱蓄熱材１１に蓄熱した熱によって加温状態を維持することができる。   In such a latent heat storage material A in which the latent heat storage material 11 is enclosed in the heat storage material container 10 and the plurality of heat storage material containers 10,... Are stored in the container storage portion 2 of the building material body 1, for example, indoors When it is constructed on the floor base material in the floor portion, a constant temperature effect that keeps the temperature of the floor surface or the room constant by the heat storage effect of the latent heat storage material 11 is obtained. For example, even when the heating state (cold temperature state) by the electric heater or the hot water pipe (cold water pipe) is stopped at the time of floor heating (floor cooling), the constant temperature effect is obtained by the heat storage effect of the heat storage material 11 thereafter. Moreover, if there is solar radiation on the indoor floor surface and the floor surface is heated, the heat is stored in the latent heat storage material 11, and even if the solar radiation stops thereafter, the heat is stored by the heat stored in the latent heat storage material 11. Can be maintained.

上記建材本体１の裏面に形成されている容器収容部２は、建材本体１の長さ方向に対向する両端部の一方から他方まで連続して延びる１列の凹部３を有する。この凹部３の長さ方向の端部は、建材本体１の長さ方向端面に到達して開口しておらず、その手前までの位置にある。   The container housing part 2 formed on the back surface of the building material main body 1 has a row of recesses 3 continuously extending from one end to the other of both ends facing the length direction of the building material main body 1. The end portion of the concave portion 3 in the length direction reaches the end surface in the length direction of the building material main body 1 and is not open, and is in a position up to that side.

また、蓄熱材容器１０の代わりに潜熱蓄熱材１１をマイクロカプセル化し樹脂に均一に内添して薄板状に成形した樹脂板を用いても良い。   Further, instead of the heat storage material container 10, a resin plate may be used in which the latent heat storage material 11 is microencapsulated and uniformly added to the resin and formed into a thin plate shape.

そして、上記凹部３の長さ方向の中間部には、凹部３の幅方向の両側面３ａ，３ａからそれぞれ中央側に互いに間隔をあけて対向するように突出する例えば１０〜２０ｍｍ程度の幅の複数対（図示例では５対）のずれ規制凸部４，４，…が凹部３の長さ方向に所定間隔をあけて一体に設けられている。この各対の両ずれ規制凸部４，４に対し凹部３においてその長さ方向両側に位置する部分の凹部３がそれぞれ容器収容スペース５，５，…となっていて、該各容器収容スペース５に蓄熱材容器１０が収容されている。   And in the intermediate part of the length direction of the said recessed part 3, it protrudes so that it may mutually oppose from the both sides 3a and 3a of the width direction of the recessed part 3 to the center side, respectively, for example, and the width | variety of about 10-20 mm A plurality of pairs (five pairs in the illustrated example) of the shift restricting convex portions 4, 4,... Are integrally provided with a predetermined interval in the length direction of the concave portion 3. The concave portions 3 located on both sides of the concave portion 3 in the lengthwise direction with respect to the pair of both deviation regulating convex portions 4, 4 are respectively container accommodating spaces 5, 5,. The heat storage material container 10 is accommodated in the storage.

上記各対のずれ規制凸部４，４は、例えば図３に拡大して示すように、凹部３の幅方向両側面３ａ，３ａから平面視で矩形状に突出している。この他、図４に示すように、凹部３の幅方向両側面３ａ，３ａから平面視で円弧状に突出していてもよく、その他の形状でもよい。   For example, as shown in an enlarged view in FIG. 3, the pair of shift restricting convex portions 4 and 4 protrudes in a rectangular shape in plan view from both side surfaces 3 a and 3 a in the width direction of the concave portion 3. In addition, as shown in FIG. 4, it may protrude in circular arc shape by planar view from the width direction both sides 3a and 3a of the recessed part 3, and another shape may be sufficient as it.

また、図５に示すように、上記容器収容部２の凹部３の底面３ａと側面３ｂとの境界角部３ｃ、及び凹部３の底面３ａとずれ規制凸部４の側面４ａとの境界角部（図示せず）は、いずれも、上記蓄熱材容器１０周囲の角部１０ａに対応して、外側に膨出する断面円弧形状に形成されている。   Further, as shown in FIG. 5, the boundary corner 3 c between the bottom surface 3 a and the side surface 3 b of the concave portion 3 of the container housing portion 2 and the boundary corner portion between the bottom surface 3 a of the concave portion 3 and the side surface 4 a of the displacement regulating convex portion 4. Each (not shown) is formed in a circular arc shape that bulges outward corresponding to the corner 10a around the heat storage material container 10.

（潜熱蓄熱建材の製造方法）
次に、このような潜熱蓄熱建材Ａ（片面に容器収容部２を有する建材本体１と、該建材本体１の容器収容部２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１１が封入された複数の蓄熱材容器１０，１０，…とを備えた潜熱蓄熱建材Ａ）を製造する方法の実施形態について説明する。 (Method for manufacturing latent heat storage building materials)
Next, the latent heat storage building material A (stored in the building material body 1 having the container housing part 2 on one side and the container housing part 2 of the building material body 1 is repeatedly melted and solidified according to the temperature to store and release heat. An embodiment of a method for producing a latent heat storage building material A) having a plurality of heat storage material containers 10, 10,.

まず、図７に示すように、未加工の建材本体１の裏面において、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を切削する。この溝部７は、たとえばプレーナ（機械鉋）等を用いて、大まかにかつ素早く加工することができる。   First, as shown in FIG. 7, on the back surface of the unprocessed building material main body 1, a groove portion 7 that is continuous from one end portion to the other end portion in the length direction is cut at the center position in the width direction of the building material main body 1. To do. The groove 7 can be processed roughly and quickly using, for example, a planar (mechanical rod).

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）の部位を該部位間に一定の残部を残してルータ加工により幅方向両側に拡張する。   Next, a plurality of (six) portions spaced apart by a predetermined distance in the length direction in the groove portion 7 are expanded to both sides in the width direction by router processing, leaving a certain remaining portion between the portions.

このことで、建材本体１の裏面に長さ方向の一端部から他端部まで連続して延びる上記凹部３と、この凹部３の長さ方向の中間部に、凹部３の幅方向両側面３ａ，３ａからそれぞれ中央側に互いに間隔（溝部７の幅）をあけて対向するように突出する複数対のずれ規制凸部４，４，…とを有する容器収容部２を形成する。つまり、上記ルータ加工時に、加工により残された残部がずれ規制凸部４，４，…となる。   By this, the said recessed part 3 continuously extended from the one end part of a length direction to the other end part in the back surface of the building material main body 1, and the width direction both sides | surfaces 3a of the recessed part 3 in the intermediate part of the length direction of this recessed part 3 , 3a, a container housing portion 2 is formed having a plurality of pairs of shift restricting convex portions 4, 4,... Protruding so as to face each other with a gap (width of the groove portion 7) from the center side. That is, at the time of the router processing, the remaining portion left by the processing becomes the shift restricting convex portions 4, 4,.

尚、この容器収容部２の各容器収容スペース５に蓄熱材容器１０を収容した後、蓋材１４が容器収容部２の開口を閉じるように建材本体１の裏面に接合される。   In addition, after accommodating the thermal storage material container 10 in each container accommodating space 5 of this container accommodating part 2, the lid | cover material 14 is joined to the back surface of the building material main body 1 so that the opening of the container accommodating part 2 may be closed.

したがって、この実施形態においては、建材本体１の裏面に容器収容部２が形成され、この容器収容部２は、建材本体１の長さ方向の一端部から他端部まで連続して延びる凹部３を有し、この凹部３の途中に、複数対のずれ規制凸部４，４，…が凹部３の幅方向に対向するように一体に突設され、凹部３においてずれ規制凸部４，４，…を除いた複数の容器収容スペース５，５，…にそれぞれ蓄熱材容器１０，１０，…が収容されている。そのため、その各蓄熱材容器１０が凹部３の長さ方向に位置ずれしようとしても、対となった両ずれ規制凸部４，４によって規制されるので、蓄熱材容器１０の位置ずれに起因して建材本体１表面で温度むらが生じることはなく、均等な蓄熱効果が得られる。   Therefore, in this embodiment, the container accommodating part 2 is formed in the back surface of the building material main body 1, and this container accommodating part 2 is the recessed part 3 extended continuously from the one end part of the length direction of the building material main body 1 to the other end part. In the middle of the concave portion 3, a plurality of pairs of shift restriction convex portions 4, 4... Are integrally projected so as to face the width direction of the concave portion 3. Are accommodated in a plurality of container housing spaces 5, 5,... Excluding. Therefore, even if each of the heat storage material containers 10 tries to be displaced in the length direction of the recess 3, the heat storage material container 10 is regulated by the paired displacement regulating convex portions 4, 4. Thus, temperature unevenness does not occur on the surface of the building material body 1 and an even heat storage effect is obtained.

また、この建材を壁材のように立てて施工しても、蓄熱材容器１０が落下することはない。   Moreover, even if this building material is stood and constructed like a wall material, the heat storage material container 10 does not fall.

また、容器収容部２は、建材本体１の凹部３の長さ方向の途中に複数対のずれ規制凸部４，４，…が一体に突設されたものであるので、従来のように仕切り板を接着する作業は不要であり、その接着不良により仕切り板が外れる虞れもなく、蓄熱材容器１０の位置ずれを確実に防止して信頼性を高めることができ、その構造を高い生産性で実現してコストダウンをも図ることができる。   Further, since the container housing portion 2 is formed by integrally projecting a plurality of pairs of shift restricting convex portions 4, 4,... In the middle of the length direction of the concave portion 3 of the building material main body 1, The work of bonding the plates is unnecessary, there is no fear that the partition plate will come off due to poor bonding, the displacement of the heat storage material container 10 can be reliably prevented and the reliability can be improved, and the structure has high productivity. This can be realized with a cost reduction.

上記蓄熱材容器１０に封入されている潜熱蓄熱材１１は固定及び液体の相変化により熱の出入りが生じるものであり、液体から固体になると体積が減少し、逆に固体から液体に変化すると体積が増大する。そして、できるだけ潜熱蓄熱材１１の容量を増やして蓄熱効果を上げるために、容器収容部２での蓄熱材容器１０のスペースを潜熱蓄熱材１１が固体状態にあるときの大きさに合わせた場合、液相状態に変化した際に、その体積の増加分だけスペースが不足することとなり、蓄熱材容器１０が容器収容部２からはみ出すこととなる。しかし、この実施形態では、容器収容部２は建材本体１の長さ方向の一端部から他端部まで連続して延びる凹部３を有し、その凹部３内において互いに間隔をあけて対向する両ずれ規制凸部４，４間に蓄熱材容器１０のない開放スペース６が形成されているので、潜熱蓄熱材１１が液相状態に変化して容器２の体積が増大した際に、この開放スペース６が蓄熱材容器１０の膨張を吸収する空間となり、その開放スペース６によって膨張分が吸収される。よって、可能な限り潜熱蓄熱材１１の容量を増やして蓄熱効果を上げながらも、その膨張時の容器のはみ出しを防止することができる。   The latent heat storage material 11 enclosed in the heat storage material container 10 is a material in which heat enters and exits due to fixation and liquid phase change. When the liquid changes to solid, the volume decreases. Conversely, when the liquid changes from solid to liquid, the volume changes. Will increase. And in order to increase the capacity of the latent heat storage material 11 as much as possible and increase the heat storage effect, when the space of the heat storage material container 10 in the container housing portion 2 is adjusted to the size when the latent heat storage material 11 is in a solid state, When the liquid phase state is changed, the space becomes insufficient by the increase in the volume, and the heat storage material container 10 protrudes from the container housing portion 2. However, in this embodiment, the container housing part 2 has a recess 3 that extends continuously from one end to the other end in the length direction of the building material main body 1, and both opposing each other with a gap in the recess 3. Since the open space 6 without the heat storage material container 10 is formed between the shift regulating convex portions 4 and 4, this open space when the latent heat storage material 11 changes to the liquid phase and the volume of the container 2 increases. 6 becomes the space which absorbs expansion | swelling of the thermal storage material container 10, and the expansion | swelling part is absorbed by the open space 6. FIG. Therefore, while increasing the capacity of the latent heat storage material 11 as much as possible to increase the heat storage effect, it is possible to prevent the container from protruding during the expansion.

さらに、建材本体１の長さ方向の一端部から他端部まで連続して延びる凹部３の途中に両ずれ規制凸部４，４が一体に突設されているので、これらのずれ規制凸部４，４によって建材本体１の強度を確保することができる。すなわち、ずれ規制凸部４，４がなくて凹部のみの場合のように、その直線状凹部の幅方向両端が折り目となるように幅方向に変形することで、反りや破壊が生じるのを防止することができる。また、容器収容部２において両ずれ規制凸部４，４により幅の狭い部分が形成されるので、上記変形がさらに有効に抑えられる。   Furthermore, since both deviation control convex parts 4 and 4 are integrally projected in the middle of the recessed part 3 continuously extended from the one end part of the length direction of the building material main body 1 to the other end part, these deviation control convex parts The strength of the building material body 1 can be ensured by 4 and 4. In other words, as in the case where there is no deviation regulating convex portions 4 and 4 and only the concave portion is formed, the linear concave portion is deformed in the width direction so that both ends in the width direction become creases, thereby preventing warpage and breakage. can do. In addition, since the narrow portion is formed by the deviation-regulating convex portions 4 and 4 in the container housing portion 2, the above deformation is further effectively suppressed.

また、容器収容部２の凹部３の底面３ａと側面３ｂとの境界角部３ｃ、及び凹部３の底面３ａとずれ規制凸部４の側面４ａとの境界角部は、外側に膨出する断面円弧形状であるので、建材Ａを例えば容器収容部２が裏面（下面）となるようにして床材として使用したとき等で、その表面（上面）から荷重が加わっても、その凹部３の底面３ａと側面３ｂとの境界角部、及び凹部３の底面３ａとずれ規制凸部４の側面４ａとの境界角部に応力が集中するのを回避することができ、それら境界角部からの破壊を防止することができる。   Moreover, the boundary corner | angular part 3c of the bottom face 3a and the side surface 3b of the recessed part 3 of the container accommodating part 2, and the boundary corner | angular part of the bottom face 3a of the recessed part 3 and the side face 4a of the shift | offset | difference control convex part 4 are cross sections which bulge outside. Even when a load is applied from the front surface (upper surface), for example, when the building material A is used as a flooring material with the container housing part 2 as the back surface (lower surface) because of the arc shape, the bottom surface of the recess 3 It is possible to avoid stress concentration at the boundary corner between 3a and the side surface 3b, and the boundary corner between the bottom surface 3a of the concave portion 3 and the side surface 4a of the displacement restricting convex portion 4, and breakage from these boundary corner portions Can be prevented.

また、上記境界角部が断面直角形状である場合に比べ、蓄熱材容器１０が境界角部にスムーズに密着して隙間がなくなるので、その蓄熱材容器１０自体を補強材として機能させることができるとともに、蓄熱材容器１０と建材本体１との接触面積が増大して蓄熱効果、吸放熱効果が高くなる。   In addition, since the heat storage material container 10 smoothly adheres to the boundary corner portion and there is no gap as compared with the case where the boundary corner portion has a right-angle cross section, the heat storage material container 10 itself can function as a reinforcing material. At the same time, the contact area between the heat storage material container 10 and the building material main body 1 increases, and the heat storage effect and the heat absorption / release effect are enhanced.

そして、潜熱蓄熱建材Ａの製造方法において、建材本体１の裏面に連続する溝部７を例えばプレーナ等で切削した後、この溝部７において所定間隔をあけた部位を幅方向両側に拡張するようにルータにより加工することで、容器収容部２を形成するので、プレーナ等で大まかに溝部７を切削した後に、その溝部７の幅を部分的に拡大するようにルータで加工すればよく、ずれ規制凸部４，４が一体に形成された容器収容部２であっても、加工時間を大幅に短縮することができる。   And in the manufacturing method of the latent heat storage building material A, after cutting the groove part 7 continuing on the back surface of the building material main body 1 with, for example, a planar or the like, the router is extended so that the parts spaced apart by a predetermined interval in the groove part 7 are extended to both sides in the width direction. Since the container housing portion 2 is formed by machining, the groove portion 7 may be roughly cut with a planar or the like, and then processed with a router so as to partially enlarge the width of the groove portion 7. Even in the container housing part 2 in which the parts 4 and 4 are integrally formed, the processing time can be greatly shortened.

（その他の実施形態）

In the description of the above embodiment, the container housing portion 2 has one row of recesses 3 extending in the length direction on the back surface of the building material main body 1, and the displacement regulating protrusions 4, 4,. Although it forms, as shown in FIG. 6, it shall have two rows of recessed parts 3 and 3 extended in the length direction on the back surface of the building material main body 1, and the shift control convex parts 4,4 ... Further, the number of the recesses 3 may be increased to three or more.

本発明は、各蓄熱材容器が凹部の長さ方向に位置ずれするのを規制し、信頼性を高めることができ、高い生産性で実現してコストダウンを図ることができるとともに、可能な限り潜熱蓄熱材の容量を増やして蓄熱効果を上げながら、その膨張時の容器のはみ出しを防止することができるので、極めて有用であり、産業上の利用可能性が高い。   The present invention regulates the positional displacement of each heat storage material container in the length direction of the recess, can improve reliability, can achieve high productivity and reduce costs, and as much as possible. While increasing the capacity of the latent heat storage material to increase the heat storage effect, it is possible to prevent the container from protruding during its expansion, which is extremely useful and highly industrially applicable.
