【発明の属する技術分野】
本発明は、断熱コーナーパネル及びその製造方法に関し、詳しくは、建物のコーナーにおける断熱性を伴う施工を容易・迅速におこなえるようにするとともに、このような断熱コーナーパネルの製造を平坦なパネルから容易におこない、かつ、コーナー部におけるパネル間の接続強度を高め、更に、コーナー部におけるパネル間の接続箇所の水密性を高めようとする技術に係るものである。
【０００２】
【従来の技術】
従来、表裏の金属外皮間に芯材を充填した断熱パネルを使って建物のコーナー部を施工するのに際して、断熱機能が殆どないコーナー継手の役物を使って施工するか、或いは、断熱材を薄く裏打ちした平坦なパネルを折り曲げた折り曲げパネルを使って施工するものである。
【０００３】
【発明が解決しようとする課題】
ところで、コーナー継手や平坦なパネルを折り曲げたパネルを使って、表裏の金属外皮間に芯材を充填した断熱パネルを接続するのに際して、充分な断熱性を得ることができず、接続強度も低く、水密性も低いという問題があった。
【０００４】
このような問題を解消するのに際して、表裏の金属外皮間に芯材を充填し、パネル体の上下部の一方に接続凹部を、他方に接続凸部を形成し、接続凹部側のパネル体の表面に凹所を、接続凸部側のパネル体の表面に覆い片を延出した平坦な断熱パネルを所定の曲げ角度に曲げ加工をおこなって、断熱コーナーパネルを得ることも考えられるが、大型の曲げ加工機が必要となるとともに、端部における接続凹部、接続凸部及び表面における凹所及び覆い片等が形成されていることから、これらの箇所において良好な曲げ加工をおこなうことが難しく、製造が困難となるのであり、しかして、断熱コーナーパネルのコストが著しく高くなるものである。
【０００５】
本発明はこのような問題に鑑みてなされたものであり、建物のコーナーにおける断熱性を伴う施工を容易・迅速におこなえるようにするとともに、このような断熱コーナーパネルの製造を平坦なパネルから容易に製造し、かつ、コーナー部におけるパネル間の接続強度を高め、更に、コーナー部におけるパネル間の接続箇所の水密性を高めることができる断熱コーナーパネル及びその製造方法を提供することを課題とするものである。
【０００６】
【課題を解決するための手段】
請求項１においては、表裏の金属外皮１，２間に芯材３を充填し、パネル体の上下部の一方に接続凹部４を、他方に接続凸部５を形成し、接続凹部４側のパネル体の表面に凹所６を、接続凸部５側のパネル体の表面に覆い片７を延出し、パネル体の水平方向の中間部において所定の角度に折り曲げた断熱コーナーパネルであって、パネル体の折り曲げ箇所の裏面の金属外皮２及び芯材３が切除された切除部において表面の金属外皮１が折り曲げられるとともに切除部に中間部芯材８が充填され、中間部芯材８を裏面から押さえ片９にて押さえていることを特徴とするものである。
【０００７】
このような構成によれば、表裏の金属外皮１，２間に芯材３を充填し、パネル体の上下部の一方に接続凹部４を、他方に接続凸部５を形成し、接続凹部４側のパネル体の表面に凹所６を、接続凸部５側のパネル体の表面に覆い片７を延出した平坦な断熱パネルＢを使用するのであり、このような断熱パネルＢにおいて、折り曲げ箇所の裏面の金属外皮２及び芯材３を除去して表面の金属外皮１を所定の角度に折り曲げるのであり、例えば、接続凹部４の一部を形成し、又、接続凸部５の一部を形成し、更に、凹所６及び覆い片７を形成している表面の金属外皮１の部分において不要となる部分を切断して除去しておくことで、表面の金属外皮１のみを所定の角度に容易に折り曲げることができ、このように所定の角度に折り曲げをおこなった後に、芯材３の切除部に中間部芯材８を充填して押さえ片９にて押さえることで、断熱コーナーパネルＡの製造がおこなえるのであり、しかして、平坦な断熱パネルから断熱コーナーパネルの製造を容易におこなうことができ、断熱コーナーパネルＡのコストを低減することができる。
【０００８】
このような断熱コーナーパネルＡを使用して接続凹部４と接続凸部５を、覆い片７を凹所６に嵌め込むことで、建物のコーナーにおける断熱性を伴う施工を容易・迅速におこなえる。
【０００９】
請求項２においては、パネル体の表面の覆い片７において裏面側に折り返された折り返し片１０が切除されており、覆い片７のパネル折り曲げ箇所に補強片１１ａ、１１ｂを付設していることを特徴とするものである。このような構成によれば、表面の金属外皮１のみにて形成される覆い片７の折り曲げ箇所の強度を高めることができる。
【００１０】
請求項３においては、金属外皮２及び芯材３が切除された切除部における接続凹部４及び接続凸部５部分には、パッキン受け１２が表の金属外皮１に連結されていることを特徴とするものである。このような構成によれば、裏の金属外皮２が切除された切除部においては、表面の金属外皮１の接続凹部４及び接続凸部５を形成している部分にパッキン受け１２が連結されてパッキン受け１２にパッキン１３を受けることができ、裏の金属外皮２が切除された切除部においても断熱コーナーパネルＡ，Ａ間のパネル内外の水密性を高めることができる。
【００１１】
請求項４においては請求項１と同様の作用を、請求項５においては請求項２と同様の作用を、請求項６においては請求項３と同様の作用を奏することができる。
【００１２】
【発明の実施の形態】
以下、本発明の実施の形態を説明する。図１（ａ）は断熱コーナーパネルの接続状態を示す概略斜視図、同図（ｂ）は部分概略斜視図、図２（ａ）は概略断面図、同図（ｂ）は中間品の裏面からの部分斜視図、図３は接続凹部及び接続凸部における裏の金属外皮の切断箇所を示す説明図である。
【００１３】
断熱コーナーパネルＡは、表裏の金属外皮１，２間に、例えば、ロックウールのような無機質材料からなる芯材３を充填するとともにパネル体の上部に接続凹部４を、下部に接続凸部５を形成している。接続凹部４側の表部にはパネル固定用の凹所６を、接続凸部５側の表面には覆い片７を形成している。しかして、凹所６にドリルビスや釘のような固定具１７を打込んで断熱コーナーパネルＡの上部を胴縁１５に固定し、接続凹部４に上の断熱コーナーパネルＡの接続凸部５を嵌合して接続するのであり、この場合、パネル体の固定用の凹所６に覆い片７が係入して固定具１７を隠している。このような上下方向の接続箇所には水密手段としてのシール用のパッキン１３が介装されて充分な水密性を確保している。このような断熱コーナーパネルＡは平坦な断熱パネルＢを所定の角度に折り曲げたものである。以下、断熱コーナーパネルＡの製造方法を詳述する。
【００１４】
まず、平坦な断熱パネルＢを詳述する。送り出し装置にて送り出された表裏の金属外皮１，２の両端にはロール成形により成形されて接続凸部外皮部分５ａ及び接続凹部外皮部分４ａが形成され、これら二枚の金属外皮１，２間に芯材３としてのロックウール材、珪酸カルシウム等が装填されている。珪酸カルシウム及び高密度ロックウールは耐火性及び機械的強度が高く、上記接続凸部外皮部分５ａ及び接続凹部外皮部分４ａに装填され、接続凸部５及び接続凹部４における耐火性及び機械的強度を高めている。二枚の金属外皮１，２は、接続凸部５と接続凹部４とにおいて、若干の隙間ｄが形成されて、二枚の金属外皮１，２間の熱伝導（ヒートブリッジ）を回避するようにしている。
【００１５】
断熱パネルＢの上端部に、表側の金属外皮１を裏面側に折り曲げて外壁材面に略直交する横目地側壁２５を形成し、横目地側壁２５に連ねて外壁材面に略平行となる横目地底壁２６を形成し、横目地底壁２６よりも更に一段低くパネル体の固定用の凹所６を形成し、凹所６よりも更に上端部に接続凹部４を形成している。
【００１６】
断熱パネルＢの下端部に、図４及び図５に示すように、横目地側壁２５のパネル厚さ方向の大きさＨに相当する厚さＴの横目地形成片２７を垂下し、横目地形成片２７の下端に上記横目地側壁２５に対向する横目地形成壁２８を形成し、横目地形成片２７よりも裏面側に接続凸部５を形成している。
【００１７】
断熱パネルＢの左右端部には、表側の金属外皮１を折り曲げて側壁２９を形成し、側壁２９から断熱パネルＢの厚さ方向の中間部から外側方に縦目地片３０を延出してある。このようにして断熱パネルＢを構成している。
【００１８】
以上の構成の平坦な断熱パネルＢにおいて本発明の断熱コーナーパネルＡは以下のように構成したものである。
【００１９】
図２及び図３に示すように、平坦な断熱パネルＢの左右方向の中間部でパネルの折り曲げ箇所の裏面の金属外皮２及び芯材３を切断して除去する。つまり、裏面の金属外皮２は図３の点線で示すように、パネル下端部の接続凸部５側の切除部イ、接続凹部４側の切除部ロをパネル全高にわたって切除する。更に、接続凸部５側の覆い片７の裏面側に折り返された折り返し片１０を切除する。金属外皮２及び芯材３が切除された切除部における接続凹部４及び接続凸部５部分には、金属板製のパッキン受け１２が表の金属外皮１に溶接、あるいは他の連結手段にて取付けている。
【００２０】
しかして、平坦な断熱パネルＢの裏面の金属外皮２及び芯材３が切除された切除部において表面の金属外皮１を例えば、略直角に折り曲げるのであり、折り曲げ後において、切除部に中間部芯材８を充填するのである。
【００２１】
この場合、例えば、図７に示すように、パネル体の接続凹部４側において、横目地側壁２５のようにパネルの厚さ方向と略直交する方向の板面部分には、Ｖ字状の開先きＣの形状に切断除去がおこなわれるのであり、又、横目地底壁２６のようにパネル体の表面に略平行となる板面部分には、上記開先きＣの両縁より略平行となる切断縁Ｄ，Ｄにおいて切断除去がおこなわれ、又、段差面２５ａに開先きＣと平行な切欠きＣａが、更に、凹所６の面６ａに切断縁Ｄと平行な切除縁Ｄａにて切除されていて、折り曲げた場合に、開先きＣの両縁、切断縁Ｄ，Ｄ、切欠きＣａの両縁及び切除縁Ｄａ，Ｄａが隙間なく当接するものである。このような当接縁においては、裏面から充分なシールが施されていて、水密性を高めている。
【００２２】
このような構成によれば、断熱コーナーパネルＡを製造するのに際して、表裏の金属外皮１，２間に芯材３を充填し、パネル体の上下部の一方に接続凹部４を、他方に接続凸部５を形成し、接続凹部４側のパネル体の表面に凹所６を、接続凸部５側のパネル体の表面に覆い片７を延出した平坦な断熱パネルＢを使用するのであり、このような断熱パネルＢにおいて、折り曲げ箇所の裏面の金属外皮２及び芯材３を除去して表面の金属外皮１を折り曲げるのであり、接続凹部４の一部、接続凸部５の一部、凹所６及び覆い片７を形成しているが表面の金属外皮１のみを折り曲げることで、曲げ加工を容易におこなうことができるのであり、このように所定の折り曲げをおこなった後に、芯材３の切除部に中間部芯材８を充填し、その後、押さえ片９にて押さえることで、断熱コーナーパネルＡの製造を平坦なパネルから容易におこなうことができるのであり、断熱コーナーパネルＡのコストを低減することができるのである。
【００２３】
このような断熱コーナーパネルＡ，Ａは、平坦な断熱パネルＢと同様に、接続凹部４と接続凸部５とを嵌合させ、パネル体の固定用の凹所６に覆い片７を被せて覆うことで接続して、建物のコーナーにおける断熱性を伴う施工を容易・迅速におこなうのである。
【００２４】
更に、本発明においては、パネルの折り曲げ箇所のパネル体の表面の覆い片７において金属外皮２及び芯材３が除去されるとともに裏面側に折り返された折り返し片１０が切除され、又、パネル体の表面の凹部６において金属外皮２及び芯材３が除去されていて、覆い片７及び凹部６における強度が低下しているのであり、したがって、覆い片７及び凹部６のパネル折り曲げ箇所に、例えば厚さが０．８ｍｍの金属板の補強片１１ａ、１１ｂを付設して覆い片７及び凹部６の強度を高めている。
【００２５】
具体的には、図２（ａ）に示すように、パネル体の表面の金属外皮１の折り曲げ部において、表面に離型（接着しない）機能を備え裏面に接着機能が高い融通シート１８を介して補強片１１ａをメタルグリップ（住友スリーエム株式会社製）１９にて金属外皮１に接着する。メタルグリップ１９の内面側にはウレタンフォーム発泡体２０を例えば、型枠内において発泡させて断熱を図り、更に、ウレタンフォーム発泡体２０の内面側に芯材３と同材料のロックウールのような無機質材料２１を充填するのであり、このようなロックウールのような無機質材料２１の裏面に、例えば、厚さが０．５ｍｍの金属板の押さえ片９をカバーとしてリベット２２にて止めるのである。この場合、押さえ片９と裏面の金属外皮２との間にコーキング剤２３を充填してシールを図っている。又、補強片１１ｂも上記融通シート１８を介して上記メタルグリップ１９によって凹部６の裏面に付設している。
【００２６】
このように、補強板１１ａ、１１ｂは融通シート１８を介して表の金属外皮１の折り曲げ箇所に取付けられていて、補強板１１ａ、１１ｂと金属外皮１の折り曲げ角度の差を吸収するとともに施工後における躯体の地震等による変形に伴う金属外皮１の折り曲げ角度の変更が生じても補強板１１ａ、１１ｂの剥離を防止して、補強板１１ａ、１１ｂの取付け強度の低下、ひいては、断熱コーナーパネルＡ，Ａの接続強度及びシール性の低下を防止するのである。
【００２７】
又、図３に示すように、裏の金属外皮２が切除された切除部においては、表面の金属外皮１の接続凹部４及び接続凸部５を形成している部分にパッキン受け１２が例えば、溶接等によって取付けらていて、パッキン受け１２にパッキン１３を受けることから、裏の金属外皮２が切除された切除部においても断熱コーナーパネルＡ，Ａ間の水密性を高めることができるのである。
【００２８】
この場合、図１２（ｂ）に示すように、コーナー部において重ねられるパッキン１３，１３は斜めにカットされて両面粘着テープ２４にて接着されていて、シール性を高めるとともに両パッキン１３，１３の連結強度を高めている。
【００２９】

As shown in FIGS. 2 and 3, the metal skin 2 and the core material 3 on the back surface of the bent portion of the panel are cut and removed at an intermediate portion in the left-right direction of the flat heat insulation panel B. That is, as shown by the dotted line in FIG. 3, the metal skin 2 on the back surface cuts the cut-out portion i on the connection convex portion 5 side at the lower end of the panel and the cut-out portion b on the connection concave portion 4 side over the entire panel height. Further, the folded piece 10 folded back on the back surface side of the cover piece 7 on the connection convex portion 5 side is cut out. A metal plate packing receiver 12 is attached to the metal shell 1 on the front surface by welding or other connecting means at the connection concave portion 4 and the connection convex portion 5 in the cut portion where the metal shell 2 and the core material 3 are cut. ing.
[0020]
Thus, the metal shell 1 on the front surface is bent at, for example, a substantially right angle at the cut portion where the metal shell 2 and the core material 3 on the back surface of the flat heat insulation panel B are cut off. The material 8 is filled.
[0021]
In this case, for example, as shown in FIG. 7, on the connection recess 4 side of the panel body, a V-shaped opening is formed on the plate surface portion in a direction substantially perpendicular to the thickness direction of the panel, such as the lateral joint side wall 25. The shape of the tip C is cut and removed, and the plate surface portion that is substantially parallel to the surface of the panel body, such as the horizontal bottom wall 26, is substantially parallel to both edges of the groove C. The cut edges D and D are cut and removed. Further, a notch Ca parallel to the groove C on the step surface 25a and a cut edge Da parallel to the cut edge D on the surface 6a of the recess 6 are formed. In this case, both edges of the groove C, the cutting edges D and D, both edges of the notch Ca, and the cutting edges Da and Da abut against each other without any gap. Such a contact edge is sufficiently sealed from the back surface to enhance water tightness.
[0022]
According to such a configuration, when the heat insulating corner panel A is manufactured, the core material 3 is filled between the front and back metal skins 1 and 2, and the connection recess 4 is connected to one of the upper and lower portions of the panel body and the other is connected to the other. A flat heat insulating panel B is used in which a convex portion 5 is formed, a recess 6 is formed on the surface of the panel body on the connection concave portion 4 side, and a covering piece 7 is extended on the surface of the panel body on the connection convex portion 5 side. In such a heat insulating panel B, the metal shell 2 and the core material 3 on the back surface of the bent portion are removed to bend the metal shell 1 on the front surface, and a part of the connection concave part 4, a part of the connection convex part 5, Although the recess 6 and the cover piece 7 are formed, the bending process can be easily performed by bending only the metal skin 1 on the surface, and after performing the predetermined bending in this way, the core material 3 Fill the excised part with the intermediate core 8 and then press down By pressing at 9, as it can easily be manufactured of heat insulation corner panel A from the flat panel, it is possible to reduce the cost of insulation corner panels A.
[0023]
As in the case of the flat heat insulation panel B, such heat insulation corner panels A and A are formed by fitting the connection concave portions 4 and the connection convex portions 5 and covering the cover pieces 7 with the recesses 6 for fixing the panel body. By connecting by covering, construction with thermal insulation at the corner of the building is done easily and quickly.
[0024]
Further, in the present invention, the metal outer skin 2 and the core material 3 are removed from the cover piece 7 on the front surface of the panel body at the bent portion of the panel, and the folded piece 10 folded back on the back side is cut off. Since the metal skin 2 and the core material 3 are removed in the concave portion 6 of the surface of the surface, the strength of the covering piece 7 and the concave portion 6 is reduced. Reinforcing pieces 11a and 11b of a metal plate having a thickness of 0.8 mm are provided to increase the strength of the covering piece 7 and the recessed portion 6.
[0025]
Specifically, as shown in FIG. 2 (a), in the bent portion of the metal skin 1 on the surface of the panel body, a flexible sheet 18 having a release (non-bonding) function on the surface and a high bonding function on the back surface is interposed. Then, the reinforcing piece 11a is bonded to the metal shell 1 with a metal grip 19 (manufactured by Sumitomo 3M Limited). On the inner surface side of the metal grip 19, for example, a urethane foam foam 20 is foamed in a mold to achieve heat insulation. Further, on the inner surface side of the urethane foam foam 20, a rock wool made of the same material as the core material 3 is used. The inorganic material 21 is filled, and on the back surface of the inorganic material 21 such as rock wool, for example, a pressing piece 9 of a metal plate having a thickness of 0.5 mm is used as a cover to be stopped by a rivet 22. In this case, the caulking agent 23 is filled between the pressing piece 9 and the metal shell 2 on the back surface for sealing. Further, the reinforcing piece 11 b is also attached to the back surface of the recess 6 by the metal grip 19 through the interchangeable sheet 18.
[0026]
In this way, the reinforcing plates 11a and 11b are attached to the bent portions of the outer metal shell 1 through the interchangeable sheet 18, and absorb the difference in bending angle between the reinforcing plates 11a and 11b and the outer metal shell 1 and after the construction. Even if the bending angle of the metal shell 1 is changed due to deformation of the casing due to earthquake or the like, the reinforcing plates 11a and 11b are prevented from being peeled off, and the strength of the reinforcing plates 11a and 11b is reduced. , A prevents connection strength and sealing performance from being lowered.
[0027]
Further, as shown in FIG. 3, in the excised part in which the metal shell 2 on the back is excised, the packing receiver 12 is formed on the surface of the surface of the metal skin 1 where the connection concave part 4 and the connection convex part 5 are formed. Since it is attached by welding or the like, and the packing 13 is received by the packing receiver 12, the watertightness between the heat insulating corner panels A and A can be enhanced even in the cut portion where the metal shell 2 on the back is cut.
[0028]
In this case, as shown in FIG. 12 (b), the packings 13 and 13 stacked at the corners are cut obliquely and bonded with the double-sided adhesive tape 24, thereby improving the sealing performance and the packings 13 and 13. The connection strength is increased.
[0029]
