Description

【０００１】
【発明の属する技術分野】
本発明は、建築、構築物に外断熱層を形成する断熱パネルに係るものである。
【０００２】
【従来の技術】
従来、断熱性と気密性を有する断熱下地を形成する断熱パネルには、特開平６−２９４１７２号のように、軸組間に嵌め込められる方形の枠部材と、この枠部材に固定され軸組の屋外側面に当接される釘打ち部を周囲に有する耐力壁用面部材と、この面部材の枠部材で囲まれる屋内側面に設けられた断熱部材とを主要構成部材とするものがあった。
【０００３】
【発明が解決しようとする課題】
上記のような構造のパネルでは、パネル体を軸組間に嵌挿する便宜上、枠部材は軸組よりも小さく形成するため枠体と軸組の間には隙間が生じるものであり、その隙間は枠部材の屋内側外周面に沿って配される断熱パッキンによって埋められることが記述されているが、枠部材と軸組の隙間が断熱パッキンを押し潰した状態の厚さよりも狭い場合は、パネル体の取り付けの際に断熱パッキンが擦られて脱落してしまい、また断熱パッキンの自己弾性力で復元した状態の厚さよりも広い場合は、枠部材と軸組の間を埋めることができず、いずれも断熱性、気密性の低下やその部位近傍への結露の発生を招くものであった。
【０００４】
また、耐力壁用面部材は外部との間に、外壁材のみ、もしくは外壁材および空気層を介するのみで外部の温度の変化の影響を受け易く、特に冬期の暖房使用時に於いて、耐力壁用面部材と断熱部材との境界部分に結露を生じる危惧があった。また、耐力壁用面部材と軸組が当接している部分および枠部材が熱橋になり易く、断熱性能に改善の余地があった。
【０００５】
【課題を解決するための手段】
本発明はこのような欠点を解決するために、略矩形の面材と、面材の表面における４辺の縁辺に沿った所定幅である釘打部を除いた範囲に一体化した断熱層と、面材の３辺の釘打部の表面において断熱層の側面と接するように載置した副断熱部と、断熱層と副断熱部の表面を平滑に跨いで接着するシート材とを有し、副断熱部を配さない側に接する２辺の側における副断熱部は面材を覆って面材縁から突出しないように載置し、副断熱部を配さない側に相対する側の副断熱部は所定幅に亘って釘打部の側方に突出するように載置し、副断熱部はシート材の断熱層と副断熱部の境界を軸として回動可能であり、また副断熱部を配さない側と相対する側の副断熱部の側面には表面側が突出する第１段差部を形成し、また副断熱部を配さない側の釘打部に隣接する断熱層の側面には表面側が欠切する第２段差部を形成する断熱パネルを提案する。
【０００６】
【発明の実施の形態】
以下に、図面を用いて本発明に係る断熱パネルについて説明する。図１、図２（ａ）、（ｂ）は本発明の断熱パネルの一例であり、Ａは断熱パネル、１は面材、２は断熱層、３〜５は副断熱部、６は第１段差部、７は第２段差部、８は第３段差部、９は第４段差部、１０はシート材、１１は副断熱部３を回動させる軸、１２は副断熱部４を回動させる軸、１３は副断熱部５を回動させる軸、１４〜１７は釘打部である。
【０００７】
面材１は略矩形で所定の規格寸法を有し、耐力壁としての強度ないし機能を備えているもので、例えばＪＡＳ規格に適合する構造用合板やＪＩＳ規格に適合するパーティクルボード、ＭＤＦ等からなり、所定の気密性、防湿性を有するもので、２種以上の複合板でも良い。また、各種鉄板を用いることもでき、単なるフラットな鉄板でも良いが、縁辺を折り返すことで釘打ち部に１４〜１７に相当する範囲に亘って鉄板を二重に重ねることもできる。
【０００８】
断熱層２は、面材１の表面に縁辺に沿った所定幅である釘打部１４〜１７を除いた範囲に配し、所定厚みを有するものであり、例えばスチレンフォーム（スチレンボード）、ポリウレタンフォーム（ウレタンボード）、ポリイソシアヌレートフォーム、フェノールフォーム、塩化ビニルフォーム、ポリエチレンフォーム、ポリスチレンフォーム、ユリアフォーム等の合成樹脂発泡体からなるものである。断熱層２は、面材１上での発泡による自己接着力、もしくは接着剤によって面材１の表面に取り付けるものである。
【０００９】

【００１０】
副断熱部３は、その表面全域を被覆するシート材１０にのみ接着し、断熱層２の側面、および釘打部１４とは接着せず、断熱層２とはシート材１０によってのみ繋がっており、図２（ａ）に示すように、シート材１０の断熱層２と副断熱部３との境界の軸１１を中心として回動可能なものであって、所定幅に亘って釘打部１４の側方に突出している。
【００１１】
副断熱部３は上述した構成により、断熱パネルＡを躯体Ｂに釘打ちする際には図２（ａ）に示すように副断熱部４を回動させて釘打部１４を露出させ、釘打ち終了後には図１（ａ）に示す状態に戻すことにより、釘打ちを容易に行うことができ、かつ釘打部１４が断熱欠損部とならないようにすることができる。なお、点線で示した軸１１の両端には、実線で示した切れ込み１１ａを有するものである。
【００１２】
副断熱部４は、断熱層２と同一の厚みを有し、面材１の表面の幅方向の端縁の所定幅に亘って形成した釘打部１６の表面に、断熱層２の側面と接するように載置し、釘打部１６の端縁から外方には突出しないものであり、副断熱部３と同様、断熱層２と同じ材質でも異なる材質でも良い。
【００１３】
副断熱部４は、その表面全域を被覆するシート材１０にのみ接着し、断熱層２の側面、および釘打部１６とは接着しておらず、従って断熱層４とはシート材１０によってのみ繋がっており、図２（ｂ）に示すように、シート材１０の断熱層２と副断熱部３との境界の軸１２を中心として回動可能なものである。上述した構成により、断熱パネルＡを躯体Ｂに釘打ちする際には図２（ｂ）に示すように副断熱部４を回動させて釘打部１６を露出させ、釘打ち終了後には図１（ａ）に示す状態に戻すことにより、釘打ちを容易に行うことができ、かつ釘打部１６が断熱欠損部とならないようにすることができる。
【００１４】
副断熱部５は、断熱層２と同一の厚みを有し、面材１の表面の長手方向に沿った中央部の所定幅に亘って形成した釘打部１７の表面に、その両側面を断熱層２の側面と接するように載置し、副断熱部３、４と同様、断熱層２と同じ材質でも異なる材質でも良い。
【００１５】
副断熱部５は、その表面全域を被覆するシート材１０にのみ接着し、断熱層２の側面、および釘打部１７とは接着しておらず、従って片側の断熱層２とシート材１０によってのみ繋がっており、図２（ａ）に示すように、シート材１０の断熱層２と副断熱部５との境界の軸１３を中心として回動可能なものである。上述した構成により、断熱パネルＡを躯体Ｂに釘打ちする際には図２（ａ）に示すように副断熱部５を回動させて釘打部１７を露出させ、釘打ち終了後には図１（ａ）に示す状態に戻すことにより、釘打ちを容易に行うことができ、かつ釘打部１７が断熱欠損部とならないようにすることができる。なお、１３ａは切断線であり、シート材１０は切断線１３ａにおいて切断されている。
【００１６】
第１段差部６は、副断熱部３の側面に形成し、外側面において表面側を突出させ、裏面側に面した平滑面６ａを形成するものである。
【００１７】
第２段差部７は、断熱層２の副断熱部３と相対する側の幅方向の端縁に形成し、外側面において表面側を欠截し、裏面側に面した平滑面７ａを形成するもので、隣接する断熱パネルＡの第２段差部を形成した際に、平滑面６ａと平滑面７ａを接触させることで断熱欠損部を皆無とすることができ、断熱下地の断熱性の向上に有効である。なお、平滑面６ａと面材１の表面との距離△Ｓ、平滑面７ａと面材１との距離△Ｔとの間は、△Ｓ≒△Ｔなる関係にあり、また、平滑面６ａの外側端と釘打部１４の外側端との水平距離を△Ｘ、平滑面７ａの内側端と釘打部１５の外側端との水平距離を△Ｙとすると、△Ｘ≦△Ｙなる関係にある。なお、第１段差部６と第２段差部７は、断熱パネルＡ同士が隣接した際に、合致するような形状に形成するものである。
【００１８】
第３段差部８は、副断熱部５の一方側面に形成し、表面側を突出させて平滑面８ａを有し、第４段差部９は、断熱層２の副断熱部５と当接する側に形成し、表面側を欠截して平滑面９ａを有するものであり、第３段差部８と第４段差部９はそれぞれ合致する形状に形成する。第３段差部８と第４段差部９を、それぞれ合致する形状に形成することにより、万が一副断熱部５を回動した際に断熱層２、副断熱部５が擦れて削れたり、圧縮されたりして一部欠けることがあっても、釘打後に副断熱部５を回動させて平滑面８ａと平滑面９ａを接触させることにより、断熱欠損部を皆無とすることを可能とし、断熱下地の断熱性の向上に有効である。
【００１９】
シート材１０は、断熱層２と副断熱部３〜５を平滑に跨ぐシート状物からなり、アスベスト紙、クラフト紙、アスファルトフェルト、金属箔（Ａｌ、Ｆｅ、Ｐｂ、Ｃｕ）、合成樹脂シート、ゴムシート、布シート、石膏紙、水酸化アルミ紙、ガラス繊維不織布等の１種、または２種以上をラミネートしたもの、あるいは防水処理、難燃処理されたシート状物、もしくは通気性防水シート等からなるものである。
【００２０】
シート材１０は、断熱層２と副断熱部３〜５を表面において平滑に跨いでかつ断熱層２、副断熱部３〜５の全てと接着しており、かつ、副断熱部３〜５は面材１及び断熱層２と分離していることから、副断熱部３は軸１１を、副断熱部４は軸１２を、副断熱部５は軸１３をそれぞれ中心として、回動可能となるものであり、シート材１０と断熱層２、副断熱層３〜５との接着は、接着剤や両面テープによる微小な範囲の接着、もしくは全面接着等の何れでも良い。また、上述したように、副断熱層３〜５の回動を容易ならしめるために、シート材１０の適宜箇所に切れ込み１０ａ、切断線１３ａを設けるのが好ましい。
【００２１】
釘打部１４〜１７は、断熱パネルＡを躯体Ｂに釘打ちする範囲であり、釘打部１４〜１６は面材１の表面に縁辺に沿った所定幅の部分、釘打部１７は面材１の表面の長手方向に沿った中央部の所定幅の部分である。
【００２２】
ここで、断熱パネルＡを躯体Ｂに取り付ける過程について説明する。まず、図３に示すように、軸１１を中心として副断熱部３を、かつ軸１３を中心として副断熱部５を回動させた断熱パネルＡ₁を、予め取り付けておいた断熱パネルＡ₀と隣接する位置に配し、釘打部１４、１５、１７において釘、ビス等の固定具αによって躯体Ｂに固定する。次に、図４に示すように、副断熱部３、５を回動させ、釘打部１４、１７を隠ぺいすると共に、断熱パネルＡ₀の第２段差部７の平滑面７ａと断熱パネルＡ₁の第１段差部６の平滑面６ａとを接触させる。
【００２３】
次に、図５に示すように、軸１２を中心として副断熱部４を回動させて露出させた釘打部１６に固定具αを打ち込み、断熱パネルＡ₁を躯体Ｂに完全に固定し、副断熱部４を回動させて釘打部１６を隠ぺいし、断熱パネルＡ₁の取り付けを完了する。上述した工程を繰り返して、図６のように断熱パネルＡ₂、Ａ₃と連続して躯体Ｂに取り付けていくことにより、躯体Ｂの外側に図７に示すような断熱欠損部や熱橋のない外断熱層１８を形成することができる。
【００２４】
なお、図７中の点線で囲んだａ部の拡大図である図８に示すように、断熱パネルＡ₁の第２段差部７の側面と、断熱パネルＡ₂の第１段差部６の側面の間にはそれぞれ、△ｌ、△ｍ（△ｌ≒△ｍ）の隙間が生じる場合があるが、断熱パネルＡ₁の第２段差部７の平滑面７ａと断熱パネルＡ₂の第１段差部６の平滑面６ａとを接触させることにより、断熱欠損部となることがない。また、平滑面６ａ、７ａの幅の範囲において、断熱パネルＡの取り付け位置の誤差を許容することができる。
【００２５】
最後に、図９に示すように外断熱層１８の外側から、胴縁１９を取り付け、任意の外装材を取り付けることによって外壁の形成を完了するものである。
【００２６】
なお、本発明に係る断熱パネルは、図１０（ａ）、（ｂ）、図１１（ａ）、（ｂ）に示すような構成を採ることもできる。すなわち、図１０（ａ）は、シート材１０の一方の端部と、副断熱層５上のシート材１０を延長し、施工後に防水シートを重ね合わせることによって、外断熱層１８の外面に位置する防水シートに隙間をなくし、壁面の防水性を完全なものとすることを可能とした断熱パネルＡの例である。図１０（ｂ）は、副断熱部３、５の側面を傾斜するように形成することで、副断熱層３、５の回動を容易ならしめた例である。
【００２７】
図１１（ａ）、（ｂ）は、面材１の裏面側に、遮音シート２０を面材１と一体に配した例である。遮音シート２０には、比重が大きく柔軟性に富んだ材質を用いるのが好ましく、例えば鉛等を主成分としたシート材が挙げられるもので、断熱層１８の形成時に、全ての断熱パネルＡにおける内部に面する面材１の全面を被覆することにより、屋外からの騒音が屋内に伝わるのを防止し、居住性の向上を図るものである。なお、図１１（ａ）においては面材１の裏面の副断熱層３側において遮音シート２０を突出させた例、図１１（ｂ）においては面材１の裏面の全域をシート材２０で被覆した例を示している。
【００２８】
【発明の効果】
以上説明したように、本発明に係る断熱パネルには、▲１▼副断熱部は断熱層との境界部近辺のシート材を軸として回動可能となるため、一旦副断熱部を回動させて釘打部を露出させつつ釘打を行い、釘打完了後に釘打部を副断熱部を被覆することができ、施工が容易である。▲２▼第１段差部と第２段差部を係合させることにより、断熱欠損部のない理想的な外断熱構造を形成することができる。▲３▼第１段差部と第２段差部の幅の範囲において、となり合う断熱パネル同士の間隔の誤差を吸収し、確実に外断熱構造を形成することができる。▲４▼面材の裏面側に遮音シートを配すれば、屋外からの騒音の遮断に有効な断熱パネルとなる。等の特徴、効果がある。

BACKGROUND OF THE INVENTION
The present invention relates to a heat insulating panel for forming an outer heat insulating layer on a building or a structure.
[0002]
[Prior art]
Conventionally, a heat insulating panel that forms a heat insulating base having heat insulating properties and air tightness includes a rectangular frame member that is fitted between shaft assemblies and a shaft assembly fixed to the frame members as disclosed in JP-A-6-294172. Some of the main structural members are a bearing member for a load bearing wall that has a nailing portion that is in contact with the outdoor side surface, and a heat insulating member that is provided on an indoor side surface surrounded by a frame member of the surface member. .
[0003]
[Problems to be solved by the invention]
In the panel having the structure as described above, for the convenience of inserting the panel body between the shaft assemblies, the frame member is formed smaller than the shaft assembly, so that a gap is generated between the frame body and the shaft assembly. Is described as being filled with a heat insulating packing disposed along the outer peripheral surface of the indoor side of the frame member, but when the gap between the frame member and the shaft assembly is narrower than the thickness of the state in which the heat insulating packing is crushed, If the insulation packing is rubbed off when the panel body is attached, and the thickness is larger than the thickness restored by the self-elasticity of the insulation packing, the space between the frame member and the shaft assembly cannot be filled. In either case, the heat insulating property and the airtightness were deteriorated and the condensation in the vicinity of the portion was caused.
[0004]
In addition, the bearing member for the load bearing wall is easily affected by external temperature changes only between the outer wall material or the outer wall material and the air layer between the exterior and the bearing wall. There was a risk of dew condensation at the boundary between the surface member and the heat insulating member. In addition, the portion where the bearing wall surface member and the shaft assembly are in contact with each other and the frame member easily become a thermal bridge, and there is room for improvement in heat insulation performance.
[0005]
[Means for Solving the Problems]
In order to solve such drawbacks, the present invention provides a substantially rectangular face material, and a heat insulating layer integrated in a range excluding a nail hammering portion having a predetermined width along the four edges on the surface of the face material, And a sub-heat insulating part placed on the surface of the nail part on the three sides of the face material so as to be in contact with the side surface of the heat-insulating layer, and a sheet material that smoothly bonds the surface of the heat-insulating layer and the sub-heat-insulating part. The side of the secondary heat insulation on the two sides contacting the side where the secondary heat insulation part is not arranged is placed so as to cover the face material and not protrude from the edge of the face material, and is opposite to the side where the secondary heat insulation part is not provided The auxiliary heat insulating part is placed so as to protrude to the side of the nail-driving part over a predetermined width, and the auxiliary heat insulating part is rotatable about the boundary between the heat insulating layer of the sheet material and the auxiliary heat insulating part, and the side surface of the secondary insulating portion opposite sides with side not provided a secondary insulating portion to form a first stepped portion surface protrudes, also on the side not provided a secondary insulating portion nail The side surface of the insulating layer adjacent to the part surface is proposed a heat insulating panels forming a second stepped portion of the notch on.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The following describes about the insulation panel according to the present invention with reference to the drawings. FIG. 1, FIG. 2 (a), (b) is an example of the heat insulation panel of this invention, A is a heat insulation panel, 1 is a face material, 2 is a heat insulation layer, 3-5 is a sub-heat insulation part, 6 is 1st. Stepped portion, 7 is a second stepped portion, 8 is a third stepped portion, 9 is a fourth stepped portion, 10 is a sheet material, 11 is a shaft for rotating the auxiliary heat insulating portion 3, and 12 is rotated for the auxiliary heat insulating portion 4. A shaft to be rotated, 13 is a shaft for rotating the auxiliary heat insulating portion 5, and 14 to 17 are nailing portions.
[0007]
The face material 1 is substantially rectangular and has a predetermined standard dimension, and is provided with strength or function as a load bearing wall. For example, a structural plywood conforming to the JAS standard, a particle board conforming to the JIS standard, MDF, etc. That is, it has predetermined airtightness and moisture resistance, and two or more composite plates may be used. Various iron plates can also be used, and a simple flat iron plate may be used. However, by folding the edge, the iron plate can be doubled over a range corresponding to 14 to 17 in the nail driving portion.
[0008]
The heat insulating layer 2 is disposed on the surface of the face material 1 in a range excluding the nailing portions 14 to 17 having a predetermined width along the edge, and has a predetermined thickness. For example, styrene foam (styrene board), polyurethane It is made of a synthetic resin foam such as foam (urethane board), polyisocyanurate foam, phenol foam, vinyl chloride foam, polyethylene foam, polystyrene foam, urea foam and the like. The heat insulating layer 2 is attached to the surface of the face material 1 by self-adhesive force by foaming on the face material 1 or an adhesive.
[0009]
The sub heat insulating portion 3 has the same thickness as the heat insulating layer 2, and the side surface of the heat insulating layer 2 is formed on the surface of the nail hammer 14 formed over the predetermined width of the edge in the longitudinal direction on the surface of the face material 1. It is placed so as to be in contact and protrudes to the side of the nailing portion 14 over a predetermined width. Styrene foam (styrene board), polyurethane foam (urethane board), polyisocyanurate foam, phenol foam, chloride It is made of a synthetic resin foam such as vinyl foam, polyethylene foam, polystyrene foam, urea foam or the like, and may be the same material as the heat insulating layer 2 or a different material.
[0010]
The sub heat insulating portion 3 is bonded only to the sheet material 10 covering the entire surface thereof, is not bonded to the side surface of the heat insulating layer 2 and the nail driving portion 14, and is connected to the heat insulating layer 2 only by the sheet material 10. As shown in FIG. 2 (a), the sheet material 10 can be rotated around an axis 11 at the boundary between the heat insulating layer 2 and the sub heat insulating portion 3, and the nail driven portion 14 extends over a predetermined width. Protrudes sideways.
[0011]
Due to the above-described configuration, when the heat insulating panel A is nailed to the housing B, the sub heat insulating portion 3 rotates the sub heat insulating portion 4 to expose the nail driving portion 14 as shown in FIG. By returning to the state shown in FIG. 1A after the completion of the driving, the nail driving can be easily performed and the nail driving portion 14 can be prevented from becoming a heat-insulating defect portion. In addition, the both ends of the axis | shaft 11 shown with the dotted line have the notch | incision 11a shown with the continuous line.
[0012]
The sub heat insulating portion 4 has the same thickness as the heat insulating layer 2, and the side surface of the heat insulating layer 2 is formed on the surface of the nail hammer 16 formed over the predetermined width of the edge in the width direction of the surface of the face material 1. They are placed so as to be in contact with each other and do not protrude outward from the edge of the nailing portion 16, and may be the same material as the heat insulating layer 2 or a different material like the sub heat insulating portion 3.
[0013]
The sub heat insulating portion 4 is bonded only to the sheet material 10 covering the entire surface thereof, and is not bonded to the side surface of the heat insulating layer 2 and the nail striking portion 16. Therefore, the heat insulating layer 4 is only bonded to the sheet material 10. As shown in FIG. 2 (b), they are connected and can rotate about an axis 12 at the boundary between the heat insulating layer 2 and the sub heat insulating portion 3 of the sheet material 10. With the configuration described above, when nailing the heat insulation panel A to the housing B, as shown in FIG. 2 (b), the sub heat insulation portion 4 is rotated to expose the nail driving portion 16, and after the nail driving is finished, By returning to the state shown in 1 (a), it is possible to easily perform nail driving and to prevent the nail driving portion 16 from becoming a heat-insulating defect portion.
[0014]
The sub heat insulating part 5 has the same thickness as the heat insulating layer 2, and both side surfaces thereof are formed on the surface of the nail driving part 17 formed over a predetermined width of the center part along the longitudinal direction of the surface of the face material 1. It may be placed so as to be in contact with the side surface of the heat insulating layer 2, and the same material as the heat insulating layer 2 or a different material may be used as in the sub heat insulating portions 3 and 4.
[0015]
The sub heat insulating portion 5 is bonded only to the sheet material 10 covering the entire surface thereof, and is not bonded to the side surface of the heat insulating layer 2 and the nail hammering portion 17, and therefore, by the heat insulating layer 2 and the sheet material 10 on one side. As shown in FIG. 2A, the sheet material 10 is rotatable about the axis 13 at the boundary between the heat insulating layer 2 and the sub heat insulating portion 5. With the configuration described above, when nailing the heat insulation panel A to the housing B, as shown in FIG. 2 (a), the auxiliary heat insulating portion 5 is rotated to expose the nail driving portion 17, and after the nail driving is finished, By returning to the state shown in 1 (a), nailing can be easily performed, and the nail driving portion 17 can be prevented from becoming a heat-insulating defect portion. In addition, 13a is a cutting line, and the sheet | seat material 10 is cut | disconnected in the cutting line 13a.
[0016]
The 1st level | step-difference part 6 is formed in the side surface of the sub heat insulation part 3, makes the surface side protrude in an outer surface, and forms the smooth surface 6a which faced the back surface side.
[0017]
The second stepped portion 7 is formed at the edge in the width direction on the side of the heat insulating layer 2 facing the sub heat insulating portion 3, lacks the surface side on the outer surface, and forms a smooth surface 7 a facing the back surface side. Therefore, when the second step portion of the adjacent heat insulation panel A is formed, the heat insulation defect portion can be eliminated by bringing the smooth surface 6a and the smooth surface 7a into contact with each other, thereby improving the heat insulation property of the heat insulation base. It is valid. The distance ΔS between the smooth surface 6a and the surface of the face material 1 and the distance ΔT between the smooth surface 7a and the face material 1 are in a relationship of ΔS≈ΔT, and the smooth surface 6a When the horizontal distance between the outer end and the outer end of the nail driving portion 14 is ΔX, and the horizontal distance between the inner end of the smooth surface 7a and the outer end of the nail driving portion 15 is ΔY, the relationship ΔX ≦ ΔY is established. is there. In addition, the 1st level | step-difference part 6 and the 2nd level | step-difference part 7 are formed in the shape which matches, when the heat insulation panels A adjoin.
[0018]
The third stepped portion 8 is formed on one side surface of the sub heat insulating portion 5 and has a smooth surface 8a protruding from the surface side, and the fourth stepped portion 9 is a side in contact with the sub heat insulating portion 5 of the heat insulating layer 2. The third stepped portion 8 and the fourth stepped portion 9 are formed in a shape that matches each other. By forming the third step portion 8 and the fourth step portion 9 in matching shapes, the heat insulating layer 2 and the sub heat insulating portion 5 are scraped or compressed when the sub heat insulating portion 5 is rotated. Even if a part is missing, the auxiliary heat insulating part 5 is rotated after nailing to bring the smooth surface 8a and the smooth surface 9a into contact with each other.
