Description

本発明は、外張断熱構造と、その外張断熱構造の施工方法に関する。 The present invention relates to an external heat insulating structure and a method of constructing the external heat insulating structure.

木造建物の外側に張る外張断熱パネルは、モジュール単位の幅で構成されている。
外張断熱パネルにおいて、建物への施工性を考慮して、断熱材を囲む外枠を組んで構成することが考えられる。 The outer insulation panel that extends to the outside of the wooden building is composed of the width of each module.
It is conceivable that the outer heat insulating panel is constructed by assembling an outer frame surrounding the heat insulating material in consideration of workability to the building.

また、特許文献１において、特殊な形態の外張断熱パネルが提案されている。
その外張断熱パネルは、木造軸組み構造の建物用で、周縁部が軸組材の室外側の面に接合される構造用面材と、その周縁部を除いた室内側の面の下部に付設され且つ下側の水平な土台の上面に当接可能な位置決め用の下部水平部材と、構造用面材の周縁部を除いた室外側の面の幅方向中央部に付設され且つ上下方向に延びる外装材固定用の垂直部材と、この垂直部材に密着してその両側の構造用面材の周縁部を除く室外側の面に貼着された断熱材とを備えている。
このような外張断熱パネルが軸組に組付けられた状態の断熱壁においては、断熱材が存在しないために構造用面材の周縁部が露出した溝部が軸組材に沿って生じており、その軸組材に沿って生じる溝部が、断熱壁補完部材を使用して断熱施工される。 Further, Patent Document 1 proposes a special form of an external heat insulating panel.
The external heat insulating panel is for a building with a wooden frame structure, and the structural face material whose peripheral edge is joined to the outdoor surface of the frame material and the lower part of the indoor surface excluding the peripheral edge. A lower horizontal member for positioning that is attached and can contact the upper surface of the lower horizontal base, and an attached lower horizontal member in the width direction of the outdoor surface excluding the peripheral edge of the structural facing material and in the vertical direction. It includes a vertical member for fixing the extending exterior material, and a heat insulating material that is in close contact with the vertical member and is attached to the outdoor surface of the structural surface material on both sides except the peripheral portion.
In the heat insulating wall in which such an external heat insulating panel is assembled to the frame, a groove having an exposed peripheral edge of the structural face material is generated along the frame because there is no heat insulating material. , The groove formed along the frame member is heat-insulated using the heat-insulating wall complementary member.

そして、断熱壁補完部材は、溝部に沿って軸組材に釘打ちされる概略角材状の外装材固定用の芯材と、この芯材に凹凸係合して溝部に嵌込まれる概略角柱状の補完断熱材との組合せにより構成される。
芯材は、垂直部材と等しい厚さおよび略等しい幅の断面寸法を有するもので、その室外側の面には、複数の凸部と凹部が交互に所定ピッチで形成されている。
補完断熱材は、その厚さが断熱材の厚さと等しく、幅が溝部の幅に対応して設定されており、この補完断熱材の幅方向中央部には、芯材の各凸部が貫通する複数の嵌合孔が長手方向に沿って所定ピッチで形成され、かつ、芯材の各凸部を除いた部分が嵌合する嵌合溝が形成されている。
以上の断熱壁補完部材の芯材は、溝部に沿ってその幅方向中央部に配置され、凹部の底が構造用面材の周縁部を介して軸組材に釘打ちされて、補完断熱材は、各嵌合孔に芯材の各凸部を貫通させて溝部に嵌合される。 The heat insulating wall complementary member includes a core material for fixing a roughly square lumber-like exterior material that is nailed to the shaft assembly along the groove portion, and a roughly prismatic columnar shape that engages with the core material in an uneven manner and is fitted into the groove portion. It is composed of a combination with the complementary heat insulating material of.
The core material has a cross-sectional dimension equal to that of the vertical member and substantially the same width, and a plurality of convex portions and concave portions are alternately formed at a predetermined pitch on the outdoor surface thereof.
The thickness of the complementary heat insulating material is equal to the thickness of the heat insulating material, and the width is set corresponding to the width of the groove portion. Each convex portion of the core material penetrates through the central portion in the width direction of the complementary heat insulating material. A plurality of fitting holes to be fitted are formed at a predetermined pitch along the longitudinal direction, and a fitting groove is formed in which a portion of the core material excluding each convex portion is fitted.
The core material of the above-mentioned heat insulating wall complementary member is arranged in the central portion in the width direction along the groove portion, and the bottom of the recess is nailed to the shaft assembly material via the peripheral edge portion of the structural facing material to be nailed to the complementary heat insulating material. Is fitted into the groove by passing each convex portion of the core material through each fitting hole.

しかし、単純に外枠を組んで外張断熱パネルを構成すると、外枠の分重くなってしまう。 However, if the outer frame is simply assembled to form the outer heat insulating panel, the weight of the outer frame becomes heavier.

特に、特許文献１の特殊形状の外張断熱パネルでは、構造用面材、下部水平部材及び垂直部材の分重くなってしまう。
さらに、断熱材が存在しないために構造用面材の周縁部が露出した溝部が軸組材に沿って生じ、その軸組材に沿って生じる溝部に、特殊な構造による芯材及び補完断熱材により構成される断熱壁補完部材を使用して、追加の断熱施工をする必要があった。 In particular, in the specially shaped external heat insulating panel of Patent Document 1, the structural face material, the lower horizontal member, and the vertical member become heavier.
Further, since there is no heat insulating material, a groove portion in which the peripheral edge of the structural face material is exposed is generated along the shaft assembly material, and a core material and a complementary heat insulating material having a special structure are formed in the groove portion formed along the shaft assembly material. It was necessary to carry out additional insulation work using a heat insulating wall complementary member composed of.

本発明の課題は、外枠をなくして軽量化による施工性の向上及びコスト低減が図れて、断熱ラインの連続性を確保できる外張断熱構造を提供することである。 An object of the present invention is to provide an external heat insulating structure capable of ensuring continuity of a heat insulating line by eliminating an outer frame and improving workability and reducing costs by reducing the weight.

(Embodiment)
FIG. 1 is a perspective view showing an external heat insulating panel according to the present invention. As shown in FIG. 1 (a), the external heat insulating panel according to the present invention includes a first wide external heat insulating panel 10 and FIG. As shown in b), three patterns of the second wide outer heat insulating panel 20 and the standard outer heat insulating panel 30 are prepared.
The first wide outer heat insulating panel 10, the second wide outer heat insulating panel 20, and the standard outer heat insulating panel 30 of these three patterns all have different widths, but all have the same height of 908 mm and thickness of 72 mm.

先ず、標準用外張断熱パネル３０は、図２に示す壁パネル１のモジュール寸法と同じ幅９１０ｍｍに形成されており、防腐処理した厚さ１２ｍｍの標準用合板３１に、フェノールフォームにより形成した厚さ６０ｍｍの標準用断熱材３２を接着剤で接着したものである。 First, the standard external heat insulating panel 30 is formed to have a width of 910 mm, which is the same as the module size of the wall panel 1 shown in FIG. A standard heat insulating material 32 having a size of 60 mm is adhered with an adhesive.

なお、モジュールとは、建物のあらゆる部分（本実施形態においては特に壁の幅寸法）を一定の大きさの倍数関係に整える際の基準となる寸法をいい、特に限定されるものではないが、例えば８００ｍｍ、９００ｍｍ、９１０ｍｍ、１０００ｍｍ等の寸法がある。例えば、モジュールを９１０ｍｍとすると、ハーフモジュールは４４５ｍｍ、クォーターモジュールは２２７．５ｍｍとなる。本実施の形態のモジュール（Ｍ）は９１０ｍｍとされている。 The module refers to a standard dimension for arranging all parts of the building (particularly the width dimension of the wall in the present embodiment) in a multiple relationship of a certain size, and is not particularly limited. For example, there are dimensions such as 800 mm, 900 mm, 910 mm, and 1000 mm. For example, assuming that the module is 910 mm, the half module is 445 mm and the quarter module is 227.5 mm. The module (M) of this embodiment is 910 mm.

次に、第一幅広外張断熱パネル１０は、標準用外張断熱パネル３０より大きい幅１０４５ｍｍに形成されており、防腐処理した幅１０４５ｍｍ、厚さ１２ｍｍを有する第一幅広合板１１に、フェノールフォームにより形成した幅１０４５ｍｍ、厚さ６０ｍｍを有する第一幅広断熱材１２を接着剤で接着したものである。 Next, the first wide outer heat insulating panel 10 is formed to have a width of 1045 mm, which is larger than the standard outer heat insulating panel 30, and is formed on a first wide plywood 11 having an antiseptic treatment width of 1045 mm and a thickness of 12 mm, and phenol foam. The first wide heat insulating material 12 having a width of 1045 mm and a thickness of 60 mm formed by the above method is adhered with an adhesive.

そして、第二幅広外張断熱パネル２０は、第一幅広外張断熱パネル１０より大きい幅１０６７ｍｍに形成されており、防腐処理した幅１０６７ｍｍ、厚さ１２ｍｍを有する第二幅広合板２１に、フェノールフォームにより形成した幅９９５ｍｍ、厚さ６０ｍｍを有する第二幅広断熱材２２を接着剤で接着したものである。 The second wide outer insulation panel 20 is formed to have a width of 1067 mm, which is larger than the first wide outer insulation panel 10, and is formed on a second wide plywood 21 having an antiseptic-treated width of 1067 mm and a thickness of 12 mm. The second wide heat insulating material 22 having a width of 995 mm and a thickness of 60 mm formed by the above method is adhered with an adhesive.
