本発明は、建築パネルに関するものであって、例えば、壁材や床材などの建材として使用可能な建築パネルに関する。 The present invention relates to a building panel, for example, a building panel that can be used as a building material such as a wall material or a flooring material.

従来、建築パネルとして、二枚の金属外皮の間に断熱性を有する芯材を充填したサンドイッチパネルが提案されている。またサンドイッチパネルにパラフィンを内蔵した建築パネルも提案されている（特許文献１参照）。この建築パネルは、パラフィンが凝固状態と融解状態とで相変化するときの潜熱を利用して温度調節機能が付与されたものである。 Conventionally, as a construction panel, a sandwich panel in which a core material having a heat insulating property is filled between two metal shells has been proposed. An architectural panel in which paraffin is incorporated in a sandwich panel has also been proposed (see Patent Document 1). This building panel is provided with a temperature control function using latent heat when paraffin undergoes a phase change between a solidified state and a molten state.

特公平６−７８６５５号公報Japanese Patent Publication No. 6-78655

しかし、パラフィンを内蔵した建築パネルでは、パラフィンの相変化に伴ってパラフィンの体積が大きく増減するものであり、この体積の増減により、金属外皮に応力がかかって金属外皮が変形することがあり、この結果、建築パネルの外観が低下する場合があった。 However, in a building panel with built-in paraffin, the volume of paraffin greatly increases and decreases with the phase change of the paraffin, and this increase and decrease of the volume may cause stress on the metal skin and deform the metal skin. As a result, the appearance of the building panel may be deteriorated.

本発明は上記の点に鑑みてなされたものであり、温度調節機能を有し、外観の低下が生じにくい建築パネルを提供することを目的とするものである。 This invention is made | formed in view of said point, and it aims at providing the building panel which has a temperature control function and does not produce the fall of an external appearance easily.

本発明に係る建築パネルは、二枚の金属外皮の間に芯材が充填され、前記金属外皮と前記芯材との間に潜熱蓄熱部材が設けられた建築パネルであって、前記金属外皮と前記芯材との間には、最も体積が増加した状態の前記潜熱蓄熱部材が収容可能な収容空間が形成され、前記潜熱蓄熱部材は前記金属外皮と前記芯材との少なくとも一方に固定されずに前記収容空間に収容されていることを特徴とするものである。 The building panel according to the present invention is a building panel in which a core material is filled between two metal skins, and a latent heat storage member is provided between the metal skin and the core material, and the metal skin and An accommodation space that can accommodate the latent heat storage member having the largest volume is formed between the core material, and the latent heat storage member is not fixed to at least one of the metal shell and the core material. It is housed in the housing space.

本発明にあっては、前記芯材にはその表面に凹部が形成され、この凹部と前記金属外皮との間に前記収容空間が形成されていることが好ましい。 In the present invention, it is preferable that a concave portion is formed on the surface of the core member, and the accommodating space is formed between the concave portion and the metal outer skin.

本発明にあっては、前記金属外皮にはその外面に突出する突出部が形成され、この突出部と前記芯材との間に前記収容空間が形成されていることが好ましい。 In the present invention, it is preferable that the metal skin is provided with a protruding portion that protrudes to the outer surface, and the housing space is formed between the protruding portion and the core member.

本発明にあっては、前記芯材と前記潜熱蓄熱部材との接着性を低減するための剥離剤が前記潜熱蓄熱部材の表面に設けられていることが好ましい。 In this invention, it is preferable that the release agent for reducing the adhesiveness of the said core material and the said latent heat storage member is provided in the surface of the said latent heat storage member.

本発明は、潜熱蓄熱部材の体積が最も増加した状態になっても収容空間に収めることができ、相変化により潜熱蓄熱部材の体積が増減しても金属外皮に応力がかかりにくくすることができるものであり、従って、本発明は、潜熱蓄熱部材により温度調節機能を有しても外観の低下が生じにくいものである。 The present invention can be accommodated in the accommodation space even when the volume of the latent heat storage member reaches the maximum state, and even if the volume of the latent heat storage member increases or decreases due to phase change, it is possible to make it difficult to apply stress to the metal skin. Therefore, in the present invention, even if the latent heat storage member has a temperature adjustment function, the appearance is hardly deteriorated.

以下、本発明を実施するための形態を説明する。 Hereinafter, modes for carrying out the present invention will be described.

本実施の形態の建築パネル１は、図１（ａ）及び図２（ａ）に示すように、二枚の金属外皮２，３の間に芯材４を充填したサンドイッチパネルとして形成され、さらに図１（ｂ）及び図２（ｂ）に示すように、潜熱蓄熱部材５を内蔵して形成されている。 As shown in FIGS. 1 (a) and 2 (a), the building panel 1 of the present embodiment is formed as a sandwich panel in which a core material 4 is filled between two metal shells 2 and 3, and As shown in FIG. 1B and FIG. 2B, the latent heat storage member 5 is built in.

金属外皮２，３は平板状の金属板にロール成形等などの加工を施して所定の形状に形成される。金属外皮２，３は従来から建材を形成する際に使用される金属板で形成することができ、例えば、鋼板、亜鉛めっき鋼板、ガルバリウム鋼板（登録商標）、エスジーエル（登録商標）鋼板、塩ビ鋼板、塗装鋼板などを挙げることができる。金属外皮２，３の板厚も特に限定は無く、例えば、０．３〜２．０ｍｍとすることができる。 The metal shells 2 and 3 are formed in a predetermined shape by subjecting a flat metal plate to processing such as roll forming. The metal shells 2 and 3 can be formed of metal plates conventionally used when forming building materials, such as steel plates, galvanized steel plates, Galvalume steel plates (registered trademark), SGL (registered trademark) steel plates, PVC steel plates. And coated steel sheet. The plate thickness of the metal shells 2 and 3 is not particularly limited, and can be, for example, 0.3 to 2.0 mm.

芯材４としては断熱性を有するものであればよく、さらに防火性や耐火性を有するものであることが好ましい。具体的には、芯材４としてはロックウールやグラスウールなどの無機繊維材や、ウレタンフォームやフェノールフォームなどの樹脂発泡体等を用いることができる。芯材４はその断熱性やパネル強度等を考慮して、厚み２０〜１５０ｍｍ、３０〜２００ｋｇ／ｍ^３にするのが好ましいが、これに限定されるものではない。芯材４は金属サンドイッチパネル１の全体にわたって一枚物であっても良いし、複数個のブロック状物を並設して芯材４を形成しても良い。また樹脂発泡体の芯材４の場合、金属外皮２（又は３）の表面で液状の樹脂材料（ウレタンやフェノールなど）を発泡させて形成することができる。また、建築パネル１の周端部には、上記無機繊維材や樹脂発泡材よりも耐火性の高い材料で形成された耐火芯材を用いることができる。耐火芯材としては、例えば、石膏や珪酸カルシウムなどの無機材料からなるものを用いることができる。金属外皮２，３と芯材４とは接着剤等を用いて接着されて一体化することができる。また芯材４を金属外皮２（又は３）の表面で液状の樹脂材料を発泡させて形成する場合は、液状の樹脂材料の自己接着により、金属外皮２，３と芯材４とを接着して一体化することができる。 The core material 4 has only to have heat insulation properties, and preferably has fire resistance and fire resistance. Specifically, as the core material 4, an inorganic fiber material such as rock wool or glass wool, or a resin foam such as urethane foam or phenol foam can be used. The core material 4 is preferably 20 to 150 mm in thickness and 30 to 200 kg / m ³ in consideration of its heat insulating properties and panel strength, but is not limited thereto. The core material 4 may be a single piece over the entire metal sandwich panel 1, or the core material 4 may be formed by arranging a plurality of block-like objects in parallel. In the case of the resin foam core material 4, it can be formed by foaming a liquid resin material (such as urethane or phenol) on the surface of the metal shell 2 (or 3). Moreover, the fireproof core material formed with the fireproof material higher than the said inorganic fiber material and resin foam material can be used for the surrounding edge part of the building panel 1. FIG. As a fireproof core material, what consists of inorganic materials, such as gypsum and a calcium silicate, can be used, for example. The metal shells 2 and 3 and the core material 4 can be integrated by being bonded using an adhesive or the like. When the core material 4 is formed by foaming a liquid resin material on the surface of the metal shell 2 (or 3), the metal shells 2, 3 and the core material 4 are bonded by self-adhesion of the liquid resin material. Can be integrated.

建築パネル１にはその一端（例えば、上端）に嵌合凸部６が形成され、他端（例えば、下端）に嵌合凹部７が形成されていても良い。この場合、隣接して配設される建築パネル１、１を嵌合凸部６と嵌合凹部７との嵌合により接続することができ、接続強度を高めることができる。 The building panel 1 may have a fitting projection 6 formed at one end (for example, the upper end) and a fitting recess 7 at the other end (for example, the lower end). In this case, the adjacent construction panels 1 and 1 can be connected by fitting the fitting convex portion 6 and the fitting concave portion 7, and the connection strength can be increased.

潜熱蓄熱部材５は潜熱を利用して熱を蓄えるものである。潜熱蓄熱部材５は相変化により吸熱したり排熱したりするように形成されている。このような潜熱蓄熱部材５は、例えば、袋体８に蓄熱材９を封入して形成されている。袋体８は、例えば、アルミニウム箔などの熱伝導性の良い金属箔で形成されている。蓄熱材９は例えばパラフィンで形成されている。また蓄熱材９は例えばパラフィンを含んで形成されている。また蓄熱材９は例えばパラフィンを熱可塑性エラストマーなどの固定材料で固定化したもの（例えば、ＪＳＲ株式会社製の「ＣＡＬＧＲＩＰ」）で形成することができる。パラフィンは、炭素数の異なる複数種の高級（炭素数１４以上）な飽和炭化水素の混合物で形成されており、飽和炭化水素の種類や各飽和炭化水素の含有量などの組成によって所望の融点となるように設計することが容易である。パラフィンは、吸熱することにより融解状態となり、排熱することで凝固状態となる。蓄熱材９は袋体８に封入されているので、パラフィンが融解状態で液状となっても、蓄熱材９は袋体８から漏れ出しにくいものである。また蓄熱材９がパラフィンを固定材料で固定化したものである場合は、パラフィンが融解状態となっても、蓄熱材９がゲル状態となるだけで流動性が低いものであるため、蓄熱材９は袋体８からさらに漏れ出しにくいものである。蓄熱材９は例えば板状に形成される。また蓄熱材９は例えば粒状に形成され、多数の粒状の蓄熱材９が袋体８に封入されて潜熱蓄熱部材５が形成される。蓄熱材９としては、融点が４〜８０℃で、潜熱量が１７０〜２２０ｋＪ／ｋｇのものを用いるのが好ましい。また、融点や潜熱量が異なる複数種の蓄熱材９を用いて潜熱蓄熱部材５を形成してもよい。 The latent heat storage member 5 stores heat using latent heat. The latent heat storage member 5 is formed so as to absorb heat or exhaust heat by phase change. Such a latent heat storage member 5 is formed, for example, by enclosing a heat storage material 9 in a bag body 8. The bag body 8 is formed of a metal foil having good thermal conductivity such as an aluminum foil, for example. The heat storage material 9 is made of, for example, paraffin. The heat storage material 9 is formed including paraffin, for example. The heat storage material 9 can be formed of, for example, paraffin fixed with a fixing material such as a thermoplastic elastomer (for example, “CALGRIP” manufactured by JSR Corporation). Paraffin is formed from a mixture of a plurality of higher-grade (more than 14 carbon atoms) saturated hydrocarbons having different carbon numbers, and has a desired melting point depending on the type of saturated hydrocarbon and the content of each saturated hydrocarbon. It is easy to design. Paraffin becomes a molten state by absorbing heat and becomes a solidified state by exhausting heat. Since the heat storage material 9 is sealed in the bag body 8, the heat storage material 9 is difficult to leak out of the bag body 8 even when paraffin is melted and becomes liquid. Further, when the heat storage material 9 is obtained by fixing paraffin with a fixing material, even if the paraffin is in a molten state, the heat storage material 9 is in a gel state and has low fluidity. Is more difficult to leak from the bag body 8. The heat storage material 9 is formed in a plate shape, for example. Further, the heat storage material 9 is formed in a granular form, for example, and a large number of granular heat storage materials 9 are enclosed in the bag body 8 to form the latent heat storage member 5. As the heat storage material 9, it is preferable to use a material having a melting point of 4 to 80 ° C. and a latent heat amount of 170 to 220 kJ / kg. The latent heat storage member 5 may be formed using a plurality of types of heat storage materials 9 having different melting points and latent heat amounts.

潜熱蓄熱部材５は、例えば、矩形状のシート状や板状に形成されている。潜熱蓄熱部材５の大きさは特に限定されないが、取扱いの容易性などから、例えば、一辺が５０〜５００ｍｍで厚みが５〜３０ｍｍの矩形状とすることができる。尚、この大きさは、最も体積が増加した状態の潜熱蓄熱部材５のものである。一枚の建築パネル１は一個又は複数個の潜熱蓄熱部材５を有して形成されている。蓄熱材９が建築パネル１の面方向においてほぼ均等量に位置するように潜熱蓄熱材５が配列されていることが好ましい。また建築パネル１は温度調整機能を十分に発揮するために、一枚の建築パネル１に対して０．３〜２．０ｋｇ／ｍ^２の蓄熱材９を保持していることが好ましいが、この保持量に限定されるものではない。 The latent heat storage member 5 is formed in, for example, a rectangular sheet shape or plate shape. Although the magnitude | size of the latent heat storage member 5 is not specifically limited, From the ease of handling etc., it can be set as the rectangular shape whose side is 50-500 mm and thickness is 5-30 mm, for example. In addition, this magnitude | size is the thing of the latent-heat storage member 5 in the state where the volume increased most. One building panel 1 is formed with one or a plurality of latent heat storage members 5. It is preferable that the latent heat storage material 5 is arranged so that the heat storage material 9 is located in an approximately equal amount in the surface direction of the building panel 1. The building panel 1 preferably holds 0.3 to 2.0 kg / m ² of the heat storage material 9 for a single building panel 1 in order to sufficiently exhibit the temperature adjustment function. The amount is not limited.

そして、潜熱蓄熱部材５は、一方の金属外皮２と芯材４との間に設けられている。ここで、一方の金属外皮２とは、建築パネル１を施工した場合に、屋内側に向く方の金属外皮２である。建築パネル１を施工した場合に、屋外側に向く金属外皮３と芯材４との間に潜熱蓄熱部材５を設けても、潜熱蓄熱部材５の吸熱や排熱の作用が屋内側に伝わりにくくなり、屋内に対する建築パネル１の温度調節機能が十分に発揮できない場合がある。 The latent heat storage member 5 is provided between one metal skin 2 and the core material 4. Here, one metal skin 2 is the metal skin 2 that faces the indoor side when the building panel 1 is constructed. When the building panel 1 is constructed, even if the latent heat storage member 5 is provided between the metal shell 3 facing the outdoor side and the core material 4, the heat absorption and exhaust heat action of the latent heat storage member 5 is not easily transmitted to the indoor side. Therefore, the temperature control function of the building panel 1 for indoors may not be sufficiently exhibited.

潜熱蓄熱部材５は、一方の金属外皮２と芯材４との間に設けた収容空間１０に収容されている。収容空間１０は最も体積が増加した状態の潜熱蓄熱部材５が収容可能な大きさに形成されている。すなわち、上記のように潜熱蓄熱部材５がパラフィンを含んで形成されている場合、凝固状態と融解状態との相変化に伴って体積が増減するものである。例えば、パラフィンの場合、凝固状態（固相）から融解状態（液相）に変化する場合、体積が約２０％大きくなる（膨張する）。逆に、パラフィンは、融解状態（液相）から凝固状態（固相）に変化する場合、体積が約２０％小さくなる（収縮する）。従って、収容空間１０は、最も体積が増加した状態（蓄熱材９のパラフィンが融解した状態）での潜熱蓄熱部材５の体積を基準にし、これが収容可能な大きさに形成されている。 The latent heat storage member 5 is accommodated in an accommodation space 10 provided between one metal skin 2 and the core material 4. The accommodation space 10 is formed in a size that can accommodate the latent heat storage member 5 with the largest volume. That is, when the latent heat storage member 5 is formed to contain paraffin as described above, the volume increases or decreases with the phase change between the solidified state and the molten state. For example, in the case of paraffin, when the state changes from a solidified state (solid phase) to a molten state (liquid phase), the volume increases (expands) by about 20%. Conversely, when paraffin changes from a molten state (liquid phase) to a solidified state (solid phase), the volume is reduced by about 20% (shrinks). Therefore, the storage space 10 is formed in a size that can be stored with reference to the volume of the latent heat storage member 5 in the state in which the volume is increased most (the state in which the paraffin of the heat storage material 9 is melted).

収容空間１０は、例えば、図１（ｂ）のように、芯材４の表面に形成された凹部１１の開口が金属外皮２で閉塞されることにより形成される。この場合、凹部１１の表面と金属外皮２とで囲まれて収容空間１０が形成される。また金属外皮２の外面（芯材４と反対側の面）はほぼ全体にわたって平坦面に形成される。一方、収容空間１０は、例えば、図２（ｂ）のように、金属外皮２の外面に突出して形成された突出部１２の開口が前記芯材４で閉塞されることにより形成されていても良い。この場合、突出部１２と芯材４の表面とで囲まれて収容空間１０が形成される。また芯材４の厚みは建築パネル１の全体にわたってほぼ一定に形成される。図１（ｂ）の場合は、金属外皮２の外面が平坦面に形成されるため、図２（ｂ）のような突出部１２が形成されず、建築パネル１の外観の低下が生じにくい。一方、図２（ｂ）の場合は、芯材４の厚みが略一定になるため、図１（ｂ）のような芯材４に厚みが薄い部分が形成されにくく、建築パネル１の断熱性能の低下が生じにくい。突出部１２は、例えば、建築パネル１の長手方向と平行な突条に形成されている。建築パネル１には一個又は複数個の突出部１２が形成されている。 The accommodation space 10 is formed, for example, by closing the opening of the recess 11 formed on the surface of the core material 4 with the metal skin 2 as shown in FIG. In this case, the accommodation space 10 is formed by being surrounded by the surface of the recess 11 and the metal skin 2. Moreover, the outer surface (surface on the opposite side to the core material 4) of the metal outer skin 2 is formed on a flat surface almost entirely. On the other hand, the accommodating space 10 may be formed by closing the opening of the protruding portion 12 formed to protrude from the outer surface of the metal skin 2 with the core material 4 as shown in FIG. good. In this case, the accommodation space 10 is formed by being surrounded by the protruding portion 12 and the surface of the core material 4. Further, the thickness of the core material 4 is formed substantially constant over the entire building panel 1. In the case of FIG. 1B, since the outer surface of the metal skin 2 is formed as a flat surface, the projecting portion 12 as shown in FIG. 2B is not formed, and the appearance of the building panel 1 is hardly deteriorated. On the other hand, in the case of FIG. 2B, since the thickness of the core material 4 is substantially constant, a thin portion is hardly formed on the core material 4 as shown in FIG. Is less likely to occur. The protrusion 12 is formed, for example, on a protrusion parallel to the longitudinal direction of the building panel 1. One or a plurality of protrusions 12 are formed on the building panel 1.

収容空間１０に収容された潜熱蓄熱部材５の外面は金属外皮２と芯材４との少なくとも一方と固定されていない。すなわち、潜熱蓄熱部材５は、図３（ａ）及び図４（ａ）のように、金属外皮２の収容空間１０に臨む面に固定され、芯材４の収容空間１０に臨む面に固定されない場合と、図３（ｂ）及び図４（ｂ）のように、金属外皮２の収容空間１０に臨む面に固定されず、芯材４の収容空間１０に臨む面に固定される場合とがある。さらに、金属外皮２の収容空間１０に臨む面と芯材４の収容空間１０に臨む面との両方に固定されない場合も考えられる。但し、潜熱蓄熱部材５が金属外皮２と芯材４の両方に固定されない場合は、収容空間１０内で潜熱蓄熱部材５の蓄熱材９が偏ってしまうことがあるので、潜熱蓄熱部材５の外面は金属外皮２と芯材４との少なくとも一方と固定されるのが好ましい。 The outer surface of the latent heat storage member 5 housed in the housing space 10 is not fixed to at least one of the metal skin 2 and the core material 4. That is, the latent heat storage member 5 is fixed to the surface of the metal shell 2 facing the accommodation space 10 as shown in FIGS. 3A and 4A, and is not fixed to the surface of the core material 4 facing the accommodation space 10. In some cases, as shown in FIGS. 3B and 4B, the metal shell 2 is not fixed to the surface facing the accommodation space 10 but is fixed to the surface of the core member 4 facing the accommodation space 10. is there. Furthermore, the case where it does not fix to both the surface which faces the accommodation space 10 of the metal shell 2 and the surface which faces the accommodation space 10 of the core material 4 is also considered. However, when the latent heat storage member 5 is not fixed to both the metal shell 2 and the core material 4, the heat storage material 9 of the latent heat storage member 5 may be biased in the accommodation space 10, and thus the outer surface of the latent heat storage member 5. Is preferably fixed to at least one of the metal shell 2 and the core material 4.

図１（ｂ）及び図２（ｂ）のように、潜熱蓄熱部材５が最も体積が増加した状態では、収容空間１０内において、潜熱蓄熱部材５の外面が金属外皮２と芯材４とに接触することになる。図３（ａ）及び図４（ａ）のように、潜熱蓄熱部材５が最も体積が増加した状態よりも収縮すると、収容空間１０内において、潜熱蓄熱部材５は金属外皮２側の外面が金属外皮２と固定された状態で、芯材４側の外面が芯材４から離れる方向に収縮する。 As shown in FIG. 1B and FIG. 2B, in the state where the volume of the latent heat storage member 5 is the largest, the outer surface of the latent heat storage member 5 becomes the metal skin 2 and the core material 4 in the housing space 10. Will come into contact. As shown in FIGS. 3A and 4A, when the latent heat storage member 5 contracts more than the state in which the volume is increased, the latent heat storage member 5 has a metal outer surface on the metal skin 2 side in the housing space 10. In a state of being fixed to the outer skin 2, the outer surface on the core material 4 side contracts in a direction away from the core material 4.

また図１（ｂ）及び図２（ｂ）のように、潜熱蓄熱部材５が最も体積が増加した状態では、収容空間１０内において、潜熱蓄熱部材５の外面が金属外皮２と芯材４とに接触することになる。図３（ｂ）及び図４（ｂ）のように、潜熱蓄熱部材５が最も体積が増加した状態よりも収縮すると、収容空間１０内において、潜熱蓄熱部材５は芯材４側の外面が芯材４と固定された状態で、金属外皮２側の外面が金属外皮２から離れる方向に収縮する。 Further, as shown in FIGS. 1B and 2B, in the state where the volume of the latent heat storage member 5 is the largest, the outer surface of the latent heat storage member 5 is the metal skin 2, the core material 4, and the housing space 10. Will come into contact. As shown in FIGS. 3B and 4B, when the latent heat storage member 5 contracts more than the state in which the volume is maximized, the outer surface of the latent heat storage member 5 on the core material 4 side is the core in the housing space 10. In a state of being fixed to the material 4, the outer surface on the metal skin 2 side contracts in a direction away from the metal skin 2.

このように潜熱蓄熱部材５は金属外皮２と芯材４との少なくとも一方に固定されずに収容空間１０に収容されているので、相変化により潜熱蓄熱部材５の体積が増減しても金属外皮２、３や芯材４に応力がかかりにくくすることができる。すなわち、潜熱蓄熱部材５は金属外皮２と芯材４との両方に固定されていると、図５のように、潜熱蓄熱部材５が収縮すると、金属外皮２に凹みが生じやすくなるものである。 Thus, since the latent heat storage member 5 is not fixed to at least one of the metal shell 2 and the core material 4 and is stored in the storage space 10, even if the volume of the latent heat storage member 5 increases or decreases due to phase change, the metal shell 2, 3 and the core material 4 can be made difficult to be stressed. That is, when the latent heat storage member 5 is fixed to both the metal shell 2 and the core material 4, when the latent heat storage member 5 contracts as shown in FIG. .

潜熱蓄熱部材５を固定するにあたっては、接着剤等を用いて接着するのが好ましい。金属外皮２と潜熱蓄熱部材５との接着剤及び芯材４と潜熱蓄熱部材５との接着剤は、金属外皮２、３と芯材４とを接着する接着剤と同様のものが用いられ、例えば、ウレタン系接着剤が用いられる。また、液状の樹脂材料を発泡させて芯材４を形成する場合は、液状の樹脂材料の自己接着により、芯材４と潜熱蓄熱部材５とが接着される。また、金属外皮２や芯材４と潜熱蓄熱部材５とが接着されない場合は接着剤を用いずに、潜熱蓄熱部材５の表面を金属外皮２や芯材４の表面と接触するように配置される。また、液状の樹脂材料を発泡させて芯材４を形成する場合において、芯材４と潜熱蓄熱部材５とが接着されないようにするためには、潜熱蓄熱部材５の芯材４と接触する側の表面に剥離剤を設けておくことができる。剥離剤としては、芯材４がウレタンやフェノールなどの樹脂発泡体で形成される場合は、例えば、石油ナフサなどを含有するものが用いられる。剥離剤は、例えば、塗布などの方法により、潜熱蓄熱部材５の表面に設けられる。このように剥離剤により、潜熱蓄熱部材５の表面と芯材４の表面との接着性を低減することにより、潜熱蓄熱部材５と芯材４が接着しにくくすることができる。 In fixing the latent heat storage member 5, it is preferable to bond using an adhesive or the like. The adhesive between the metal skin 2 and the latent heat storage member 5 and the adhesive between the core material 4 and the latent heat storage member 5 are the same as the adhesive that bonds the metal skins 2 and 3 and the core material 4. For example, a urethane adhesive is used. When the core material 4 is formed by foaming a liquid resin material, the core material 4 and the latent heat storage member 5 are bonded by self-adhesion of the liquid resin material. Further, when the metal skin 2 or the core material 4 and the latent heat storage member 5 are not bonded, the surface of the latent heat storage member 5 is arranged to contact the surface of the metal skin 2 or the core material 4 without using an adhesive. The Further, when the core material 4 is formed by foaming a liquid resin material, in order to prevent the core material 4 and the latent heat storage member 5 from being bonded, the side of the latent heat storage member 5 in contact with the core material 4 A release agent can be provided on the surface. As the release agent, when the core material 4 is formed of a resin foam such as urethane or phenol, for example, a material containing petroleum naphtha or the like is used. The release agent is provided on the surface of the latent heat storage member 5 by a method such as coating. Thus, by reducing the adhesiveness between the surface of the latent heat storage member 5 and the surface of the core material 4 with the release agent, the latent heat storage member 5 and the core material 4 can be made difficult to adhere.

上記のような建築パネル１は建物の屋根下地や壁や床などを形成する際に用いられる。この場合、複数枚の建築パネル１は並設されて施工されるが、隣り合う建築パネル１は嵌合凸部６と嵌合凹部７との嵌合により接続されたり、端面同士を突き合わせて接続される。また潜熱蓄熱部材５が接触する金属外皮２を屋内側に向けて施工される。本発明の建築パネル１は、通常の住宅や工場に適用することができるが、特に、温度調節が必要な建物に適用することが可能である。例えば、植物工場などで使用される閉鎖型苗生産システムユニットの壁材として建築パネル１を好適に用いることができる。また、倉庫などの保冷設備の建物を形成する際にも建築パネル１を好適に用いることができる。 The building panel 1 as described above is used when forming a roof base, wall, floor or the like of a building. In this case, although the plurality of building panels 1 are installed side by side, the adjacent building panels 1 are connected by fitting the fitting convex portion 6 and the fitting concave portion 7 or are connected by abutting the end faces. Is done. Moreover, it is constructed with the metal outer skin 2 with which the latent heat storage member 5 comes in contact facing the indoor side. The building panel 1 of the present invention can be applied to ordinary houses and factories, but can be applied particularly to buildings that require temperature control. For example, the building panel 1 can be suitably used as a wall material for a closed seedling production system unit used in a plant factory or the like. Moreover, the building panel 1 can be used suitably also when forming the building of cold storage facilities, such as a warehouse.

以下、本発明を実施例によって具体的に説明する。 Hereinafter, the present invention will be specifically described by way of examples.

（実施例１）
厚み３５ｍｍ、幅９１０ｍｍ、長さ２７００ｍｍの建築パネルを形成する。この建築パネルは二枚の金属外皮がそれぞれ厚み０．５ｍｍの亜鉛めっき鋼板で形成されている。芯材は厚み３４ｍｍのウレタンフォーム（１種）で形成されている。各金属外皮と芯材とはウレタンフォームを形成する樹脂材料の自己接着力により接着されている。建築パネルには複数の潜熱蓄熱部材が内蔵されている。 Example 1
A building panel having a thickness of 35 mm, a width of 910 mm, and a length of 2700 mm is formed. In this building panel, two metal shells are each formed of a galvanized steel sheet having a thickness of 0.5 mm. The core material is formed of urethane foam (1 type) having a thickness of 34 mm. Each metal shell and the core material are bonded by the self-adhesive force of the resin material forming the urethane foam. A plurality of latent heat storage members are built in the building panel.

潜熱蓄熱部材は袋体に多数の粒状の蓄熱材を封入して形成されている、袋体は厚み０．０１ｍｍのアルミニウム箔で形成されている。蓄熱材（ＪＳＲ株式会社製の「ＣＡＬＧＲＩＰ」）は融点が２５℃に設計されたパラフィンで形成されている。蓄熱材の形状は矩形状の板状である。一つの潜熱蓄熱部材には５００ｇの蓄熱材が封入されている。潜熱蓄熱部材は蓄熱材が完全に融解した状態（ゲル状態）で厚み１５ｍｍ、幅２８０ｍｍ、長さ１８０ｍｍに形成される。蓄熱材が完全に凝固した状態では潜熱蓄熱部材は厚み１２ｍｍ、幅２８０ｍｍ、長さ１８０ｍｍに形成される。 The latent heat storage member is formed by enclosing a large number of granular heat storage materials in a bag, and the bag is formed of an aluminum foil having a thickness of 0.01 mm. The heat storage material (“CALGRIP” manufactured by JSR Corporation) is formed of paraffin designed to have a melting point of 25 ° C. The shape of the heat storage material is a rectangular plate. One latent heat storage member is filled with 500 g of a heat storage material. The latent heat storage member is formed to have a thickness of 15 mm, a width of 280 mm, and a length of 180 mm in a state where the heat storage material is completely melted (gel state). In a state where the heat storage material is completely solidified, the latent heat storage member is formed to have a thickness of 12 mm, a width of 280 mm, and a length of 180 mm.

潜熱蓄熱部材はその片面が一方の金属外皮の芯材側の面にウレタン系接着剤（二液タイプ）で接着されている。潜熱蓄熱部材の他の片面には石油ナフサを含有する剥離剤が２〜３ｇ／ｍ^２で塗布されている。潜熱蓄熱部材は金属外皮の長手方向に７個、金属外皮の短手方向に２個並べて設けている。金属外皮の長手方向で隣り合っている潜熱蓄熱部材の端部間の間隔は１８０ｍｍとし、金属外皮の短手方向で隣り合っている潜熱蓄熱部材の端部間の間隔は１５０ｍｍとしている。そして、潜熱蓄熱部材を設けた一方の金属外皮と潜熱蓄熱部材を設けていない他方の金属外皮とを対向配置し、二枚の金属外皮の間に液状の樹脂材料を供給し、この樹脂材料を発泡させることにより、芯材を形成する。芯材の形成時には、潜熱蓄熱部材が最も体積が増加した状態であることが必要であるため、蓄熱材が完全に融解した状態となる温度で樹脂材料を発泡させる。具体的には、樹脂材料の発泡効率等も考慮して、温度約３５℃で樹脂材料を発泡させる。 One surface of the latent heat storage member is bonded to the surface of one metal skin on the core material side with a urethane-based adhesive (two-component type). A release agent containing petroleum naphtha is applied at ² to 3 g / m ² on the other surface of the latent heat storage member. Seven latent heat storage members are arranged side by side in the longitudinal direction of the metal skin and two in the short direction of the metal skin. The interval between the ends of the latent heat storage members adjacent in the longitudinal direction of the metal shell is 180 mm, and the interval between the ends of the latent heat storage members adjacent in the short direction of the metal shell is 150 mm. Then, one metal skin provided with the latent heat storage member and the other metal skin not provided with the latent heat storage member are arranged to face each other, and a liquid resin material is supplied between the two metal skins. A core material is formed by foaming. At the time of forming the core material, the latent heat storage member needs to be in a state in which the volume is increased most, and thus the resin material is foamed at a temperature at which the heat storage material is completely melted. Specifically, the resin material is foamed at a temperature of about 35 ° C. in consideration of the foaming efficiency of the resin material.

このようにして１４個の潜熱蓄熱部材を内蔵した建築パネルが形成される。この建築パネルでは、芯材の潜熱蓄熱部材が設けられている部分が凹所となり、金属外皮と凹部とで囲まれる空間が収容空間として形成される。そして、潜熱蓄熱部材が最も体積が増加した状態で芯材が形成されるため、収容空間は最も体積が増加した状態の潜熱蓄熱部材が収容可能な大きさに形成されている。また、潜熱蓄熱部材が最も体積が増加した状態から収縮する場合、潜熱蓄熱部材が金属外皮に接着され、芯材とは剥離剤により接着されていないので、潜熱蓄熱部材は厚み方向に収縮しながら芯材と離れるようになっている。 In this way, a building panel incorporating 14 latent heat storage members is formed. In this building panel, a portion where the latent heat storage member of the core material is provided becomes a recess, and a space surrounded by the metal outer skin and the recess is formed as an accommodation space. Since the core material is formed with the latent heat storage member having the largest volume, the accommodation space is formed in a size that can accommodate the latent heat storage member with the largest volume. Further, when the latent heat storage member contracts from the state in which the volume is increased most, the latent heat storage member is bonded to the metal shell and is not bonded to the core by the release agent, so the latent heat storage member is contracted in the thickness direction. It is designed to be separated from the core material.

（実施例２）
実施例１と同様の金属外皮と芯材と潜熱蓄熱部材とを用いて建築パネルを形成する。潜熱蓄熱部材はその片面が一方の金属外皮の芯材側の面に接触して配置されているが、接着されていない。潜熱蓄熱部材の他の片面には剥離剤が塗布されていない。潜熱蓄熱部材は実施例１と同様の個数と間隔で金属外皮に設けられている。そして、潜熱蓄熱部材を設けた一方の金属外皮と潜熱蓄熱部材を設けていない他方の金属外皮とを対向配置し、二枚の金属外皮の間に液状の樹脂材料を供給し、この樹脂材料を実施例１と同様の条件で発泡させることにより、芯材を形成する。 (Example 2)
A building panel is formed using the same metal skin, core material, and latent heat storage member as in Example 1. The latent heat storage member is arranged so that one surface thereof is in contact with the surface of the core of the one metal shell, but is not bonded. A release agent is not applied to the other surface of the latent heat storage member. The latent heat storage members are provided on the metal shell at the same number and interval as in the first embodiment. Then, one metal skin provided with the latent heat storage member and the other metal skin not provided with the latent heat storage member are arranged to face each other, and a liquid resin material is supplied between the two metal skins. A core material is formed by foaming under the same conditions as in Example 1.

このようにして１４個の潜熱蓄熱部材を内蔵した建築パネルが形成される。この建築パネルでは、芯材の潜熱蓄熱部材が設けられている部分が凹所となり、金属外皮と凹部とで囲まれる空間が収容空間として形成される。そして、潜熱蓄熱部材が最も体積が増加した状態で芯材が形成されるため、収容空間は最も体積が増加した状態の潜熱蓄熱部材が収容可能な大きさに形成されている。また、潜熱蓄熱部材が最も体積が増加した状態から収縮する場合、潜熱蓄熱部材が金属外皮に接着されず、芯材とは樹脂材料の自己接着力により接着されるので、潜熱蓄熱部材は厚み方向に収縮しながら金属外皮と離れるようになっている。 In this way, a building panel incorporating 14 latent heat storage members is formed. In this building panel, a portion where the latent heat storage member of the core material is provided becomes a recess, and a space surrounded by the metal outer skin and the recess is formed as an accommodation space. Since the core material is formed with the latent heat storage member having the largest volume, the accommodation space is formed in a size that can accommodate the latent heat storage member with the largest volume. Also, when the latent heat storage member contracts from the state in which the volume is maximized, the latent heat storage member is not bonded to the metal shell, and is bonded to the core by the self-adhesive force of the resin material. It is designed to move away from the metal skin while shrinking.

In this building panel, two metal shells are each formed of a galvanized steel sheet having a thickness of 0.5 mm. The metal skin has a width of 280 mm, and a protrusion is formed over the entire length in the longitudinal direction of the building panel. The width (280 mm) of the protruding portion is formed so as to accommodate a latent heat storage member in a state where the heat storage material is completely melted (gel state), and is formed to have a thickness (depth) of 15 mm, a width of 280 mm, and a length of 2700 mm.

In this building panel, a space surrounded by the core material and the protruding portion is formed as a housing space. Since the core material is formed with the latent heat storage member having the largest volume, the accommodation space is formed in a size that can accommodate the latent heat storage member with the largest volume. Further, when the latent heat storage member contracts from the state in which the volume is increased most, the latent heat storage member is bonded to the metal shell and is not bonded to the core by the release agent, so the latent heat storage member is contracted in the thickness direction. It is designed to be separated from the core material.

（実施例４）

［許容曲げ応力度］
３等分２線集中荷重載荷試験を行った。この場合、建築パネルを長手方向の両端部で水平に支持し（支持スパンは２５００ｍｍ）、建築パネルの各支持位置から８３３ｍｍの位置に上から均等な荷重を付加し、建築パネルの中央部の変位を測定した。そして、この試験による破壊荷重を測定し、断面係数及び断面二次モーメントを用いて最大曲げ応力度を計算し、さらに安全率を２として許容曲げ応力度を計算した。 [Allowable bending stress]
A three-part two-line concentrated load loading test was performed. In this case, the building panel is supported horizontally at both ends in the longitudinal direction (support span is 2500 mm), and an equal load is applied from the top to the position of 833 mm from each support position of the building panel. Was measured. Then, the breaking load by this test was measured, the maximum bending stress degree was calculated using the section modulus and the second moment of section, and the allowable bending stress degree was calculated with a safety factor of 2.

実施例１及び２の建築パネルは、許容曲げ応力度が３７０〜３８０ｋｇ／ｃｍ^２であり、比較例１の建築パネルの許容曲げ応力度５６０ｋｇ／ｃｍ^２よりもやや低下する傾向にある。しかしながら、人が全力で建築パネルに寄りかかった時の曲げ応力度は約６５０ｋｇ／ｃｍ^２であるため、実施例１及び２の建築パネルであっても、実用上、問題とならない曲げ強度を有するものである。実施例３及び４は許容曲げ応力度が８００〜８３０ｋｇ／ｃｍ^２であり、比較例１の建築パネル及び比較例２の建築パネル（許容曲げ応力度が３７５ｋｇ／ｃｍ^２）よりも曲げ強度が高くなり、比較例３の建築パネル（許容曲げ応力度が８３５ｋｇ／ｃｍ^２）に比べても、遜色のない曲げ強度を有する。 Building panels of Examples 1 and 2, the allowable bending stress intensity is 370~380kg / cm ^2, there is a tendency to slightly lower than the allowable bending stress of 560 kg / cm ² of the building panel of Comparative Example 1. However, since the degree of bending stress when a person leans against the building panel with full power is about 650 kg / cm ² , even the building panels of Examples 1 and 2 have bending strength that is not a problem in practice. Is.
