Description

本発明は、外壁材などの壁パネル等として用いられる防火断熱パネルに関するものである。   The present invention relates to a fireproof and heat insulating panel used as a wall panel such as an outer wall material.

従来より、二枚の金属外皮の間に断熱材を充填して断熱パネルを形成することが行われている（例えば、特許文献１参照）。このような断熱パネルにおいて、断熱材としてはフェノールフォームやウレタンフォームなどの樹脂系断熱材あるいはグラスウールやロックウールなどの無機系断熱材が用いられている。   Conventionally, a heat insulating panel is formed by filling a heat insulating material between two metal shells (see, for example, Patent Document 1). In such a heat insulating panel, as the heat insulating material, a resin heat insulating material such as phenol foam or urethane foam or an inorganic heat insulating material such as glass wool or rock wool is used.

しかし、樹脂系断熱材のみを用いた場合は無機系断熱材に比べて燃焼しやすいために防火性能に劣るという問題があり、 無機系断熱材のみを用いた場合は樹脂系断熱材に比べて断熱材能に劣るという問題があった。
特開２００６−１８８８９７号公報 However, there is a problem that fire resistance is inferior because it is easy to burn compared to inorganic heat insulating material when only resin heat insulating material is used, and compared with resin heat insulating material when only inorganic heat insulating material is used. There was a problem that it was inferior in heat insulating material ability.

The insertion portion 22 is formed by bending the metal skin 1 on the surface side.

防火断熱パネルＡの表面側の下部は覆い部２３で形成されている。覆い部２３は表面側の金属外皮１を断面略Ｕ字状に屈曲して形成されている。また、防火断熱パネルＡの裏面側の下部は突条部２４として突設されている。そして、覆い部２３と突条部２４の間において防火断熱パネルＡの下面に嵌合凹部７が形成されている。また、嵌合凹部７には防火断熱パネルＡの内部に向かって凹設されたパッキン収納凹部２５が設けられている。覆い部２３、突条部２４、嵌合凹部７及びパッキン収納凹部２５は防火断熱パネルＡの幅方向の略全長にわたって設けられている。また、突条部２４、嵌合凹部７及びパッキン収納凹部２５の表面のほぼ全体が、表面側（屋外側）の金属外皮１又は裏面側（屋内側）の金属外皮２で被覆されている。また、上記のパッキン収納凹部２５には二種類のパッキン２６、２７が充填されている。一方のパッキン２６は水密パッキンであって、発泡ウレタン等の合成樹脂発泡体で形成されている。他方のパッキン２７は耐火性のある遮炎パッキンであって、ロックウールなどの無機繊維材等で形成されている。水密パッキン２６は遮炎パッキン２７よりも屋外側に配置されている。   A lower portion on the surface side of the fireproof and heat insulating panel A is formed by a cover portion 23.

Further, almost the entire surface of the protrusion 24, the fitting recess 7 and the packing storage recess 25 is covered with the metal skin 1 on the front surface side (outdoor side) or the metal skin 2 on the back surface side (indoor side). The packing storage recess 25 is filled with two types of packings 26 and 27. One packing 26 is a watertight packing and is formed of a synthetic resin foam such as urethane foam. The other packing 27 is a flameproof packing having fire resistance, and is formed of an inorganic fiber material such as rock wool. The watertight packing 26 is disposed on the outdoor side of the flameproof packing 27.

上記のように断熱材３は防火断熱パネルＡの厚み方向に積層される無機系断熱材４と樹脂系断熱材５との二層で形成されている。無機系断熱材４は金属外皮１、２の間の屋外側（金属外皮１側）の略半分に充填されており、樹脂系断熱材５は金属外皮１、２の間の屋内側（金属外皮２側）の略半分に充填されている。また、嵌合凸部６には上記無機系断熱材４よりも高密度の無機系断熱材８が充填されている。高密度の無機系断熱材８は、無機系断熱材４と同様の材料で形成することができるが、無機系断熱材４よりも密度の高いものを用いる。具体的には、無機系断熱材４として密度が８０〜２００ｋｇ／ｍ３のものを用いることができ、高密度の無機系断熱材８として密度が２０１〜４００ｋｇ／ｍ３のものを用いることができる。無機系断熱材４と高密度の無機系断熱材８は金属外皮１の屋内側面に接着されており、樹脂系断熱材５は金属外皮２の屋外側面に接着されている。また、無機系断熱材４及び高密度の無機系断熱材８と樹脂系断熱材５も接着されている。 As described above, the heat insulating material 3 is formed of two layers of the inorganic heat insulating material 4 and the resin heat insulating material 5 laminated in the thickness direction of the fireproof heat insulating panel A. The inorganic heat insulating material 4 is filled in approximately half of the outdoor side (metal hull 1 side) between the metal hulls 1 and 2, and the resin heat insulating material 5 is indoor side (metal hull between the metal hulls 1 and 2. About half of the second side). Further, the fitting convex portion 6 is filled with an inorganic heat insulating material 8 having a higher density than the inorganic heat insulating material 4. The high-density inorganic heat insulating material 8 can be formed of the same material as the inorganic heat insulating material 4, but a material having a higher density than the inorganic heat insulating material 4 is used. Specifically, the inorganic heat insulating material 4 having a density of 80 to 200 kg / m 3 can be used, and the high density inorganic heat insulating material 8 having a density of 201 to 400 kg / m 3 can be used. it can. The inorganic heat insulating material 4 and the high density inorganic heat insulating material 8 are bonded to the indoor side surface of the metal skin 1, and the resin heat insulating material 5 is bonded to the outdoor side surface of the metal skin 2. Further, the inorganic heat insulating material 4, the high density inorganic heat insulating material 8, and the resin heat insulating material 5 are also bonded.

そして、複数枚の上記防火断熱パネルＡを縦横に並べて施工することにより、建物の外壁等を形成することができる。このとき、図２に示すように、防火断熱パネルＡはその頭部収納凹部２０の屋外側から柱などの壁下地材にまでドリルビスなどの固定具２８を打ち込んで固定することができる。また、上下に隣接する防火断熱パネルＡ、Ａは、下側の防火断熱パネルＡの嵌合凸部６を上側の防火断熱パネルＡの嵌合凹部７に差し込んで嵌合することにより接続される。このようにして接続すると、上側の防火断熱パネルＡの覆い部２３が頭部収納凹部２０の屋外側に位置し、固定具２８の頭部を覆い隠して外観を向上させることができる。また、下側の防火断熱パネルＡの挿入部２２を水密パッキン２６に食い込ませることができ、嵌合部分の水密性を確保することができる。挿入部２２は水密パッキン２６に小さい力で食い込ませることができるように、先細りの断面略Ｖ字状に形成されている。また、上側の防火断熱パネルＡの突条部２４は下側の防火断熱パネルＡの凹段部２１に嵌合される。   And the outer wall of a building, etc. can be formed by arranging a plurality of said fire-proof and heat-insulating panels A side by side. At this time, as shown in FIG. 2, the fireproof and heat insulating panel A can be fixed by driving a fixing tool 28 such as a drill screw from the outdoor side of the head housing recess 20 to a wall base material such as a pillar. Further, the fireproof and heat insulating panels A and A adjacent to each other are connected by inserting and fitting the fitting convex portion 6 of the lower fireproof and heat insulating panel A into the fitting concave portion 7 of the upper fireproof and heat insulating panel A. . When connected in this manner, the cover portion 23 of the upper fireproof and heat insulating panel A is positioned on the outdoor side of the head housing recess 20 and covers the head of the fixture 28 to improve the appearance. Moreover, the insertion part 22 of the lower fireproof heat insulation panel A can be made to bite into the watertight packing 26, and the watertightness of a fitting part can be ensured. The insertion portion 22 is formed in a substantially V-shaped tapered cross section so that the watertight packing 26 can be bitten with a small force. Further, the ridge portion 24 of the upper fireproof and heat insulating panel A is fitted into the concave step portion 21 of the lower fireproof and heat insulating panel A.

本発明の防火断熱パネルＡは、断熱材３を無機系断熱材４と樹脂系断熱材５とで形成したので、樹脂系断熱材５よりも燃えにくくて防火性の高い無機系断熱材４で防火性能を確保することができると共に、独立気泡により断熱性の高い樹脂系断熱材５で断熱性能を確保することができる。具体的には、無機系断熱材４としては、厚み２０〜５０ｍｍで密度８０〜２００ｋｇ／ｍ３のロックウールを用いることができ、樹脂系断熱材５としては厚み２０〜５０ｍｍで密度３５〜６０ｋｇ／ｍ３の発泡ウレタンを用いることができる。この場合、無機系断熱材４は無機材料であるため、樹脂材料の樹脂系断熱材５よりも防火性能が高い。また、樹脂系断熱材５がウレタンフォームの場合、その熱伝導率は例えば０．０２１６Ｗ／ｍｋ（密度が５０ｋｇ／ｍ３のもの）であり、無機系断熱材４がロックウールボードの場合、その熱伝導率は例えば０．０４６５Ｗ／ｍｋ（密度が１５０ｋｇ／ｍ３のもの）であり、本発明で使用する樹脂系断熱材５は無機系断熱材４よりも断熱性能が高い。 In the fireproof and heat insulating panel A of the present invention, since the heat insulating material 3 is formed of the inorganic heat insulating material 4 and the resin heat insulating material 5, the inorganic heat insulating material 4 which is less flammable than the resin heat insulating material 5 and has high fire resistance. While being able to ensure fireproof performance, the heat insulation performance can be ensured by the resin heat insulating material 5 having high heat insulation properties due to closed cells. Specifically, as the inorganic heat insulating material 4, a rock wool having a thickness of 20 to 50 mm and a density of 80 to 200 kg / m 3 can be used. As the resin heat insulating material 5, a thickness of 20 to 50 mm and a density of 35 to 60 kg can be used. / M 3 urethane foam can be used. In this case, since the inorganic heat insulating material 4 is an inorganic material, the fireproof performance is higher than that of the resin heat insulating material 5 of the resin material. Further, when the resin heat insulating material 5 is urethane foam, its thermal conductivity is, for example, 0.0216 W / mk (with a density of 50 kg / m 3 ), and when the inorganic heat insulating material 4 is rock wool board, The thermal conductivity is, for example, 0.0465 W / mk (having a density of 150 kg / m 3 ), and the resin heat insulating material 5 used in the present invention has higher heat insulating performance than the inorganic heat insulating material 4.
