Description

本発明は、鉄骨併用鉄筋コンクリート壁式構造建築物の内部と外部との間の熱の移動を小さくする断熱構造に関する。   The present invention relates to a heat insulating structure that reduces heat transfer between the inside and outside of a steel frame combined reinforced concrete wall-type structure building.

建築物の断熱構造は、建築物の省エネルギー効果に優れていることから、近年住宅等の建築物に施工されるようになってきている。建築物の断熱は、建築物の内部と外部との間の熱伝導、熱輻射、熱対流といった熱移動をできるだけ抑えることが必要で、そのために建築物の屋外側全体を断熱材で覆うように施工する外張断熱構造や建築物の屋内側全体を断熱材で覆うように施工する内張断熱構造が提案されている。   The heat insulating structure of a building is excellent in the energy saving effect of the building, and has recently been applied to a building such as a house. Insulation of a building needs to suppress heat transfer such as heat conduction, heat radiation, and heat convection between the inside and outside of the building as much as possible. The outer insulation structure to be constructed and the inner insulation structure to be constructed so as to cover the entire indoor side of the building with a heat insulating material have been proposed.

こうした断熱材で建築物全体を覆う構造とすることは、内部と外部との間の熱移動を抑えて冷暖房の効率を向上させることができ、省エネルギー効果を高めることが可能となる。例えば、特許文献1では、型枠兼用の断熱材を用いて鉄筋コンクリート壁の内側及び外側に断熱材を配置し、断熱屋根板を載置することで鉄筋コンクリート構造物の外周部を断熱するようにした点が記載されている。   Such a structure that covers the entire building with the heat insulating material can suppress the heat transfer between the inside and the outside, improve the efficiency of air conditioning and heating, and increase the energy saving effect. For example, in Patent Document 1, a heat insulating material is also used on the inside and outside of a reinforced concrete wall using a heat insulating material that also serves as a formwork, and the outer peripheral portion of the reinforced concrete structure is insulated by placing a heat insulating roof plate. Points are listed.

しかしながら、建築物全体を断熱材で隙間なく覆うことは構造上難しい場合がある。例えば、鉄筋コンクリート造や鉄骨造建築物では、バルコニー、庇、パラペット、外廊下といった外側に突出した構造を構築することが多く、こうした突出構造を通して熱移動が生じる熱橋現象で断熱効果が低下するようになる。また、窓枠といった取付部分でも断熱材で覆うことはできないため、熱橋現象が生じやすく断熱効果が低下する。   However, it may be structurally difficult to cover the entire building with a heat insulating material without a gap. For example, in reinforced concrete structures and steel structures, structures that protrude outward, such as balconies, fences, parapets, and outer corridors, are often constructed, and the thermal insulation effect is reduced by the thermal bridge phenomenon that causes heat transfer through such protruding structures. become. In addition, since a mounting portion such as a window frame cannot be covered with a heat insulating material, a thermal bridge phenomenon is likely to occur and the heat insulating effect is reduced.

このような熱橋現象に対しては、例えば、特許文献2では、断熱板に貫通孔を形成して突出構造を支持する上端支持筋及び下端支持材を挿入して構成した外断熱形成具が記載されている。また、特許文献3では、躯体外壁面に断熱層を挟んで躯体梁と平行に設けられた二重梁により外装用二重壁を構築して突出構造を構築した点が記載されている。また、特許文献4では、パラペット全体を断熱材で覆うことで建物全体の断熱性を向上させた点が記載されている。   For such a thermal bridge phenomenon, for example, in Patent Document 2, an outer heat insulating forming tool configured by inserting an upper end support bar and a lower end support member that form a through hole in a heat insulating plate to support a protruding structure is disclosed. Are listed. Further, Patent Document 3 describes that a projecting structure is constructed by constructing a double wall for exterior by a double beam provided in parallel with a frame beam with a heat insulating layer sandwiched between outer wall surfaces of the frame. Moreover, in patent document 4, the point which improved the heat insulation of the whole building by covering the whole parapet with a heat insulating material is described.

特開2007−162252号公報JP 2007-162252 A 特許第3958335号公報Japanese Patent No. 3958335 特許第4025910号公報Japanese Patent No. 4025910 特許第4198141号公報Japanese Patent No. 4198141

上述した熱橋現象は、熱伝導率のよい部材を通して外部と内部との間を熱が移動する現象であるが、上述した突出構造が外部に露出しているため、突出構造と内部構造との間で熱移動が生じると、建物の外部と内部との間の断熱効果が低下するのは避けられない。   The above-mentioned thermal bridge phenomenon is a phenomenon in which heat moves between the outside and the inside through a member having good thermal conductivity. However, since the above-described protruding structure is exposed to the outside, there is a difference between the protruding structure and the internal structure. When heat transfer occurs between them, it is inevitable that the heat insulation effect between the outside and inside of the building is reduced.

特許文献2では、突出構造との間に断熱板を設けて断熱効果を高めているものの上端支持筋や下端支持材を通して熱橋現象が生じるようになり、その分断熱効果が低下する。また、特許文献3では、断熱効果が得られるものの二重梁を構築するためのコスト負担が大きくならざるを得ない。特許文献4では、パラペットを通じた熱橋現象を確実に防止できるものの断熱材で覆うためパラペットの外観デザインに制約が生じ、また断熱材の消費量が多くなってその分コスト負担が大きくなる。   In Patent Document 2, although a heat insulating plate is provided between the protruding structure and the heat insulating effect is enhanced, a thermal bridge phenomenon occurs through the upper end supporting bars and the lower end supporting material, and the heat insulating effect is reduced accordingly. Moreover, in patent document 3, although the heat insulation effect is acquired, the cost burden for constructing a double beam must be large. In Patent Document 4, although the thermal bridge phenomenon through the parapet can be surely prevented, the external design of the parapet is restricted because it is covered with the heat insulating material, and the consumption of the heat insulating material increases, and the cost burden increases accordingly.

そこで、本発明は、こうした熱橋現象を抑止することができ十分な省エネルギー効果を発揮することが可能な鉄骨併用鉄筋コンクリート壁式構造建築物の断熱構造を提供することを目的とするものである。   Therefore, an object of the present invention is to provide a heat insulating structure for a steel frame combined reinforced concrete wall type structure capable of suppressing such a thermal bridge phenomenon and exhibiting a sufficient energy saving effect.

本発明に係る鉄骨併用鉄筋コンクリート壁式構造建築物の断熱構造は、基礎コンクリートの両側に断熱材が層状に設けられた基礎部分及び土間コンクリートの下面を覆うように断熱材が敷設された土間部分を有する床下構造と、鉄筋コンクリートの少なくとも外面を覆うように断熱材が配設された外壁構造と、屋上面を覆うように断熱材が敷設された屋上構造と、前記外壁構造に連設されたスラブ構造及び前記屋上構造を支持する鉄骨構造とを備えた鉄骨併用鉄筋コンクリート壁式構造建築物の断熱構造において、前記外壁構造又は前記屋上構造に取り付けられる部材は、長繊維補強硬化性樹脂発泡体からなる取付部材を介して取り付けられていることを特徴とする。さらに、前記外壁構造には、前記取付部材が前記断熱材の間に密着して固定されており、前記取付部材には取付金具を介して外装材が取り付けられていることを特徴とする。さらに、前記外壁構造には、前記取付部材を介して窓枠が取り付けられていることを特徴とする。さらに、前記屋上構造の周囲に突設されたパラペット構造を有しており、前記パラペット構造は、前記屋上構造に長繊維補強硬化性樹脂発泡体を介して固定された複数の支持部材に取り付けられるとともに前記屋上構造との間に断熱材が配設されていることを特徴とする。さらに、前記パラペット構造は、前記支持部材に固定された枠部材と、前記枠部材を覆うように取り付けられた外装材とを備えていることを特徴とする。   The heat insulating structure of the steel-framed reinforced concrete wall structure building according to the present invention includes a foundation part in which heat insulating material is provided in layers on both sides of the foundation concrete and a soil part in which the heat insulating material is laid so as to cover the lower surface of the soil concrete. An underfloor structure, an outer wall structure in which a heat insulating material is disposed so as to cover at least the outer surface of the reinforced concrete, a roof structure in which a heat insulating material is laid so as to cover the roof surface, and a slab structure that is connected to the outer wall structure. And a steel frame combined reinforced concrete wall structure with a steel structure that supports the roof structure, wherein the member attached to the outer wall structure or the roof structure is made of a long fiber reinforced curable resin foam. It is characterized by being attached via a member. Furthermore, the attachment member is closely fixed between the heat insulating materials on the outer wall structure, and an exterior material is attached to the attachment member via an attachment fitting. Furthermore, a window frame is attached to the outer wall structure via the attachment member. Furthermore, it has a parapet structure projecting around the roof structure, and the parapet structure is attached to a plurality of support members fixed to the roof structure via long fiber reinforced curable resin foam. And the heat insulating material is arrange | positioned between the said roof structures. Furthermore, the parapet structure includes a frame member fixed to the support member and an exterior material attached so as to cover the frame member.

上記のような構成を有することで、木質構造材に用いられる木材と同程度の機械的な強度を有し木材よりも熱伝導率の低い長繊維補強硬化性樹脂発泡体を熱橋現象が生じる箇所に設けているので、熱橋現象を抑止して断熱効果を高めることができる。   By having the above configuration, a thermal bridge phenomenon occurs in a long fiber reinforced curable resin foam having mechanical strength comparable to that of wood used for wood structure materials and lower thermal conductivity than wood. Since it is provided at the location, it is possible to suppress the thermal bridge phenomenon and enhance the heat insulation effect.

すなわち、外壁構造又は屋上構造に取り付けられる部材は、長繊維補強硬化性樹脂発泡体からなる取付部材を介して取り付けられているので、取付部分において生じやすい熱橋現象を長繊維補強硬化性樹脂発泡体からなる取付部材により抑止することが可能となる。   That is, since the member attached to the outer wall structure or the rooftop structure is attached via an attachment member made of a long fiber reinforced curable resin foam, the thermal fiber phenomenon that tends to occur in the attachment portion is caused by the long fiber reinforced curable resin foam. It becomes possible to suppress by the attachment member which consists of a body.

外壁構造では、遮熱シートや外装材を保持する取付部材を通じて熱橋現象が生じるようになるが、取付部材を長繊維補強硬化性樹脂発泡体で構成すれば断熱効果をさらに高めることができる。また、窓枠の取付部分においても窓枠の金属枠部材が壁構造の木質構造部材と接触することで熱橋現象が生じるようになるが、金属枠部材に当接する部分に長繊維補強硬化性樹脂発泡体からなる取付部材を設けて窓枠を取り付けるようにすれば、取付部材により熱橋現象が遮断されるように作用して断熱効果が高まる。   In the outer wall structure, a thermal bridge phenomenon occurs through the mounting member that holds the heat shield sheet and the exterior material. However, if the mounting member is made of a long fiber reinforced curable resin foam, the heat insulating effect can be further enhanced. In addition, a thermal bridge phenomenon occurs when the metal frame member of the window frame comes into contact with the wooden structure member of the wall structure in the mounting portion of the window frame. If an attachment member made of a resin foam is provided and the window frame is attached, the attachment member acts so that the thermal bridge phenomenon is blocked and the heat insulation effect is enhanced.

また、屋上構造では、周囲に突設されたパラペット構造を通じて熱橋現象が生じるようになるが、パラペット構造を屋上構造に支持する複数の取付部材を長繊維補強硬化性樹脂発泡体を介して固定し、屋上構造とパラペット構造との間に断熱材を配設すれば、パラペット構造と屋上構造との間の熱橋現象が遮断されるように作用して断熱効果が高まる。   In addition, in the rooftop structure, a thermal bridge phenomenon occurs through the surrounding parapet structure, but multiple mounting members that support the parapet structure on the rooftop structure are fixed via long fiber reinforced curable resin foam. And if a heat insulating material is arrange | positioned between a rooftop structure and a parapet structure, it will act so that the thermal bridge phenomenon between a parapet structure and a rooftop structure may be interrupted | blocked, and the heat insulation effect will increase.

以上のように、断熱材で覆うことができない取付部分に機械的強度が大きく熱伝導率の低い長繊維補強硬化性樹脂発泡体からなる取付部材を配設して熱橋現象を遮断することで、断熱材による断熱効果をさらに向上させて優れた省エネルギー効果を発揮することができる。   As described above, by installing a mounting member made of long fiber reinforced curable resin foam with high mechanical strength and low thermal conductivity on the mounting part that cannot be covered with a heat insulating material, the thermal bridge phenomenon is blocked. Further, the heat insulating effect by the heat insulating material can be further improved, and an excellent energy saving effect can be exhibited.

以下、本発明に係る実施形態について詳しく説明する。なお、以下に説明する実施形態は、本発明を実施するにあたって好ましい具体例であるから、技術的に種々の限定がなされているが、本発明は、以下の説明において特に本発明を限定する旨明記されていない限り、これらの形態に限定されるものではない。   Hereinafter, embodiments according to the present invention will be described in detail. The embodiments described below are preferable specific examples for carrying out the present invention, and thus various technical limitations are made. However, the present invention is particularly limited in the following description. Unless otherwise specified, the present invention is not limited to these forms.

図1は、本発明に係る実施形態に関する概略構成図である。図1に示す鉄骨併用鉄筋コンクリート壁式構造建築物は、地盤にコンクリートを打設して形成される床下構造1と、床下構造1の上部に構築される床構造2と、床下構造1の上部に構築される鉄筋コンクリート壁を備えた外壁構造3と、外壁構造3に架設される鉄筋コンクリートスラブを備えたスラブ構造4と、外壁構造3の上部に構築される鉄筋コンクリートスラブを備えた屋上構造5と、屋上構造5の周囲に取り付けられるパラペット構造6とを備えており、主要な骨組構造は公知の鉄骨材を組み合わせた鉄骨造で構成されている。   FIG. 1 is a schematic configuration diagram relating to an embodiment of the present invention. The steel frame combined reinforced concrete wall structure shown in FIG. 1 includes an underfloor structure 1 formed by placing concrete on the ground, a floor structure 2 constructed on the upper portion of the underfloor structure 1, and an upper portion of the underfloor structure 1. An outer wall structure 3 having a reinforced concrete wall to be constructed, a slab structure 4 having a reinforced concrete slab erected on the outer wall structure 3, a roof structure 5 having a reinforced concrete slab constructed on top of the outer wall structure 3, and a rooftop And a parapet structure 6 attached to the periphery of the structure 5, and the main frame structure is composed of a steel structure in which known steel frames are combined.

こうした鉄骨併用鉄筋コンクリート壁式構造建築物は、耐震強度、耐火性及び防音性に関して優れた鉄筋コンクリート造及び細くて軽量な鉄骨材を用いることで良好な施工を有する鉄骨造の両方の利点を備えた混構造である。   These reinforced concrete wall-type structures with steel frames are mixed with the advantages of both reinforced concrete structures with excellent seismic strength, fire resistance and soundproofing, and steel structures with good construction by using thin and light steel structures. It is a structure.

床下構造1は、地盤に対して公知の施工方法により鉄筋コンクリートからなる基礎コンクリート10及び土間コンクリート11が形成されている。そして、基礎コンクリート10の両側には複数の型枠ユニットパネル12が隙間なく配列されて接合している。型枠ユニットパネル12は、発泡合成樹脂材料からなる板状の断熱材であり、コンクリートを打設する際に型枠として使用され、基礎コンクリート10が形成された後は両側にそのまま接合した状態で断熱構造として用いられる。   In the underfloor structure 1, foundation concrete 10 and soil concrete 11 made of reinforced concrete are formed on the ground by a known construction method. A plurality of formwork unit panels 12 are arranged on both sides of the foundation concrete 10 without gaps and joined. The formwork unit panel 12 is a plate-shaped heat insulating material made of a foamed synthetic resin material, and is used as a formwork when placing concrete. After the foundation concrete 10 is formed, the formwork unit panel 12 is joined as it is on both sides. Used as a heat insulating structure.

断熱材として使用される発泡合成樹脂材料は、公知のものを使用すればよく、例えば、ポリスチレンフォーム、ポリプロピレンフォーム、ポリエチレンフォーム、ポリウレタンフォーム、フェノールフォーム、アクリルフォームが挙げられ、発泡合成樹脂材料以外にも、不燃性の無機質発泡材料を用いることもできる。そして、ポリスチレンフォームが断熱性及び加工性の観点からみて好ましい。   As the foamed synthetic resin material used as the heat insulating material, a known material may be used, and examples thereof include polystyrene foam, polypropylene foam, polyethylene foam, polyurethane foam, phenol foam, and acrylic foam. Moreover, a nonflammable inorganic foam material can also be used. Polystyrene foam is preferable from the viewpoints of heat insulation and processability.

また、土間コンクリート11の下面には板状の断熱材13が隙間なく敷設されており、基礎コンクリート10及び土間コンクリート11を断熱材で覆うことにより床下構造1における外部と内部との間の熱移動を抑えて断熱効果を高めている。   Further, a plate-like heat insulating material 13 is laid on the lower surface of the interstitial concrete 11 without any gap, and heat transfer between the outside and the inside of the underfloor structure 1 by covering the foundation concrete 10 and the interstitial concrete 11 with the heat insulating material. Suppresses the heat insulation effect.

床構造2は、土間コンクリート11上に立設された鋼製の床束20に支持されて大引き21が横設されており、大引き21上には根太22が配列されている。そして、根太22の上面には床板23が平面状に配列されて取り付けられている。床構造2では、床下構造1に断熱材が設けられているため、断熱材は設けられていない。   The floor structure 2 is supported by a steel floor bundle 20 erected on the soil concrete 11, and a large pull 21 is horizontally arranged on the large pull 21. And the floor board 23 is arranged and attached to the upper surface of the joist 22 in the shape of a plane. In the floor structure 2, since the heat insulating material is provided in the underfloor structure 1, the heat insulating material is not provided.

外壁構造3は、柱、梁、桁、筋交いといった公知の鉄骨材を用いて骨組みが構築され、外壁面に沿って鉄筋コンクリート壁30が形成されている。鉄筋コンクリート壁30は、鉄筋を公知の施工方法で配筋してコンクリートを打設することで構築される。鉄筋コンクリート壁30には、床下構造1と同様に型枠ユニットパネル31が両側に隙間なく配列されて全面を覆うように接合している。型枠ユニットパネル31は、型枠ユニットパネル12と同様に発泡合成樹脂材料からなる板状の断熱材であり、コンクリートを打設する際に型枠として使用され、鉄筋コンクリート壁30が形成された後は両側にそのまま接合した状態で断熱構造として用いられる。   The outer wall structure 3 is constructed of a frame using known steel frames such as columns, beams, girders and braces, and a reinforced concrete wall 30 is formed along the outer wall surface. The reinforced concrete wall 30 is constructed by placing reinforcing bars by a known construction method and placing concrete. Similar to the underfloor structure 1, the formwork unit panels 31 are arranged on both sides of the reinforced concrete wall 30 so as to cover the entire surface. The formwork unit panel 31 is a plate-like heat insulating material made of a foamed synthetic resin material like the formwork unit panel 12, and is used as a formwork when placing concrete, and after the reinforced concrete wall 30 is formed. Is used as a heat insulating structure in a state where it is directly joined to both sides.

外壁構造3の内側には、型枠ユニットパネル31を覆うように内装材32が取り付けられており、外壁構造3の外側には、型枠ユニットパネル31を覆うように遮熱シート35及び外装材33が取り付けられている。遮熱シート35と外装材33との間には通気層34が形成されており、通気層34内に常時空気を流通させることで型枠ユニットパネル31内部の水分を外部に放出するとともに外装材33の放熱を行うことができる。   An interior material 32 is attached to the inside of the outer wall structure 3 so as to cover the formwork unit panel 31, and a heat shield sheet 35 and an exterior material are provided on the outside of the outer wall structure 3 so as to cover the formwork unit panel 31. 33 is attached. A ventilation layer 34 is formed between the heat shield sheet 35 and the exterior material 33, and air is constantly circulated through the ventilation layer 34 to release moisture inside the mold unit panel 31 to the outside and the exterior material. 33 heat can be dissipated.

図2は、外装材33及び遮熱シート35の保持構造に関する垂直方向に沿う部分拡大断面図(図2(a))及び水平方向に沿う部分拡大断面図(図2(b))である。断熱材である型枠ユニットパネル31の間には外装材33及び遮熱シート35を保持するための取付部材36が固定されている。取付部材36には、取付金具37がネジ止めされている。取付金具37は、外壁構造の上下方向に延設された細幅の板状体で、両側部分が折り曲げられて段差状に形成されている。外装材33は、取付金具37の両側部分に固定されて保持され、遮熱シート35は取付部材36及び取付金具37の間に圧接保持されている。   FIG. 2 is a partially enlarged cross-sectional view along the vertical direction (FIG. 2A) and a partially enlarged cross-sectional view along the horizontal direction (FIG. 2B) regarding the holding structure of the exterior material 33 and the heat shield sheet 35. An attachment member 36 for holding the exterior material 33 and the heat shield sheet 35 is fixed between the formwork unit panels 31 which are heat insulating materials. A mounting bracket 37 is screwed to the mounting member 36. The mounting bracket 37 is a narrow plate-like body extending in the vertical direction of the outer wall structure, and is formed in a stepped shape by bending both side portions. The exterior material 33 is fixed and held on both side portions of the mounting bracket 37, and the heat shield sheet 35 is pressed and held between the mounting member 36 and the mounting bracket 37.

取付部材36に使用される材料としては、断熱性の高く機械的強度の大きい材料が用いられ、長繊維補強硬化性樹脂発泡体が好適である。長繊維補強硬化性樹脂発泡体は、無機質又は有機質の長繊維を多数本糸長方向に揃えて発泡性が付与された硬質ウレタン樹脂又は硬質ポリエステル樹脂に埋設して成形されたもので、木材と同様の機械的強度を有するとともに木材よりも低い熱伝導率を有している。例えば、硬質ウレタン樹脂からなる熱硬化性樹脂発泡体をガラス長繊維で強化したもの(例;積水化学工業株式会社製のFFU(登録商標))では、木材と同程度の比重及び機械的強度を有し、熱伝導率が木材の半分以下となっている。そのため、こうした材料を取付部材36に用いることで、外装材33の保持構造の構造材を通して発生する熱橋現象を抑止することができる。   As a material used for the attachment member 36, a material having high heat insulation and high mechanical strength is used, and a long fiber reinforced curable resin foam is preferable. The long fiber reinforced curable resin foam is formed by embedding a large number of inorganic or organic long fibers in a hard urethane resin or a hard polyester resin provided with foamability by aligning them in the length direction of the main yarn. It has similar mechanical strength and lower thermal conductivity than wood. For example, a thermosetting resin foam made of a hard urethane resin reinforced with long glass fibers (eg, FFU (registered trademark) manufactured by Sekisui Chemical Co., Ltd.) has a specific gravity and mechanical strength comparable to wood. And thermal conductivity is less than half that of wood. Therefore, by using such a material for the attachment member 36, the thermal bridge phenomenon that occurs through the structural material of the holding structure of the exterior material 33 can be suppressed.

図3は、取付部材36に関する平面図、正面図及び側面図である。取付部材36は、中心部に固定ネジを挿入する貫通孔36aが形成されており、取付部材36の4つの側面36bは、膨出するように湾曲形成されている。   FIG. 3 is a plan view, a front view, and a side view relating to the attachment member 36. The attachment member 36 has a through hole 36a into which a fixing screw is inserted at the center, and the four side surfaces 36b of the attachment member 36 are curved so as to bulge.

図4は、保持構造に関する水平方向の拡大断面図である。取付部材36は、型枠ユニットパネル31の間に形成された空隙に嵌め込まれて、貫通孔36aに挿入された固定ネジ36cにより鉄筋コンクリート壁30に固定されている。取付部材36の側面36bは、型枠ユニットパネル31に圧接して平面状に変形し隙間のない密着した状態となる。   FIG. 4 is an enlarged cross-sectional view of the holding structure in the horizontal direction. The attachment member 36 is fitted into a gap formed between the formwork unit panels 31 and is fixed to the reinforced concrete wall 30 by a fixing screw 36c inserted into the through hole 36a. The side surface 36b of the mounting member 36 is pressed into contact with the formwork unit panel 31 to be deformed into a flat shape and is in close contact with no gap.

貫通孔36aは樹脂材料が埋め込まれ、取付部材36の取付金具37の取付面は平面状に形成されており、取付部材36及び型枠ユニットパネル31の外表面はほぼ面一に形成されている。そして、取付部材36及び型枠ユニットパネル31の外表面を覆うように張り付けられた遮熱シート35は、取付金具37の中央部分の固定部37aが固定ネジにより取付部材36の取付面に固定されることで保持される。また、固定部37aの両側の保持部37bは、段差状に折り曲げられて形成されており、保持部37bの取付面に外装材33が当接してネジ止めにより保持される。取付金具37の保持部37bが段差状に形成されているため、外装材33と遮熱シート35との間に隙間が形成されて通気層34となっている。   The through hole 36a is filled with a resin material, the mounting surface of the mounting bracket 37 of the mounting member 36 is formed in a flat shape, and the outer surfaces of the mounting member 36 and the formwork unit panel 31 are substantially flush. . The heat shield sheet 35 attached so as to cover the outer surface of the mounting member 36 and the formwork unit panel 31 is fixed to the mounting surface of the mounting member 36 with a fixing portion 37a at the center of the mounting bracket 37 by a fixing screw. It is held by. The holding portions 37b on both sides of the fixed portion 37a are formed to be bent in a stepped shape, and the exterior member 33 comes into contact with the mounting surface of the holding portion 37b and is held by screws. Since the holding portion 37 b of the mounting bracket 37 is formed in a stepped shape, a gap is formed between the exterior material 33 and the heat shield sheet 35 to form the ventilation layer 34.

外壁構造3の一部は、矩形状に開口部が形成されて公知の窓枠38が取り付けられる。開口部の内周には、枠状に取付部材39が接合固定されており、窓枠38は取付部材39を介して取り付けられるようになっている。取付部材39に使用される材料には、取付部材36と同様の長繊維補強硬化性樹脂発泡体が用いられ、そのため取付部材39は木材と同程度の比重及び機械的強度を有し、熱伝導率が木材の半分以下となっている。こうした材料を取付部材39に用いることで、窓枠38から外壁構造3の構造材を通じて発生する熱橋現象を抑止することができる。   A part of the outer wall structure 3 has a rectangular opening and a known window frame 38 is attached thereto. A mounting member 39 is joined and fixed in a frame shape to the inner periphery of the opening, and the window frame 38 is mounted via the mounting member 39. The material used for the attachment member 39 is a long fiber reinforced curable resin foam similar to that of the attachment member 36. Therefore, the attachment member 39 has a specific gravity and mechanical strength comparable to that of wood, and conducts heat. The rate is less than half that of wood. By using such a material for the attachment member 39, it is possible to suppress the thermal bridge phenomenon that occurs from the window frame 38 through the structural material of the outer wall structure 3.

図5は、窓枠38の取付部分に関する一部拡大断面図である。外壁構造3の開口部の内周面に取付部材39を固定し、取付部材39に窓枠38の金属製枠部材38a及び樹脂製枠部材38bをネジ等により固定する。熱伝導率の高い金属製枠部材38aは取付部材39に固定されることで、熱橋現象は抑止され、内装材32は熱伝導率の低い樹脂製枠部材38bに接した状態となるので、内装材32を通じた熱橋現象は抑止されるようになる。そのため、窓枠38の取付部分における断熱効果を高めることが可能となる。   FIG. 5 is a partially enlarged cross-sectional view of the attachment portion of the window frame 38. The attachment member 39 is fixed to the inner peripheral surface of the opening of the outer wall structure 3, and the metal frame member 38 a and the resin frame member 38 b of the window frame 38 are fixed to the attachment member 39 with screws or the like. Since the metal frame member 38a having a high thermal conductivity is fixed to the mounting member 39, the thermal bridge phenomenon is suppressed and the interior material 32 is in contact with the resin frame member 38b having a low thermal conductivity. The thermal bridge phenomenon through the interior material 32 is suppressed. Therefore, it is possible to enhance the heat insulation effect at the attachment portion of the window frame 38.

A waterproof base material 54 laid on the upper surface of 52 via a ventilation layer 53, and a waterproof layer 55 applied on the surface of the waterproof base material 54. The corrugated steel plate 50 is fixed to the steel frame by welding or the like, and the reinforced concrete slab 51 is placed by placing the reinforcing bars in a flat shape on the upper surface of the corrugated steel plate 50 and placing concrete.

屋上構造5の全面を覆うように敷設された断熱材52は、外壁構造3の型枠ユニットパネル31の頂部に隙間なく接合しており、接合部分において確実に断熱効果を奏するようになっている。   The heat insulating material 52 laid so as to cover the entire surface of the rooftop structure 5 is joined to the top of the formwork unit panel 31 of the outer wall structure 3 without a gap, so that a heat insulating effect is surely produced at the joined portion. .

屋上構造5は、外壁構造3から外側に延設した庇5aが形成されている。庇5aは、外壁構造3から外方に突出した鉄骨材に波形鋼板50が延設されて屋上構造5と同様の構造で構築される。外壁構造3との接合部分には波形鋼板50に連結孔50aが穿設されており、連結孔50aに鉄筋を挿通して鉄筋コンクリート壁30及び鉄筋コンクリートスラブ51が連結されている。   The roof structure 5 is formed with ridges 5 a extending outward from the outer wall structure 3. The eaves 5 a is constructed with a structure similar to the rooftop structure 5 in which a corrugated steel plate 50 is extended to a steel frame projecting outward from the outer wall structure 3. A connecting hole 50a is formed in the corrugated steel plate 50 at a joint portion with the outer wall structure 3, and a reinforced concrete wall 30 and a reinforced concrete slab 51 are connected to the connecting hole 50a through a reinforcing bar.

庇5aの下面及び側面には、それぞれ断熱材52a及び52bが張り付けられており、断熱材52aは外壁構造3の型枠ユニットパネル31と隙間なく接合し、断熱材52bは断熱材52と隙間なく接合している。そのため、庇5a全体が断熱材で覆われるようになり、断熱効果が向上する。   Heat insulating materials 52a and 52b are respectively attached to the lower surface and the side surface of the flange 5a. The heat insulating material 52a is joined to the mold unit panel 31 of the outer wall structure 3 without a gap, and the heat insulating material 52b is not spaced from the heat insulating material 52. It is joined. Therefore, the entire ridge 5a is covered with a heat insulating material, and the heat insulating effect is improved.

パラペット構造6は、屋上構造5の周囲に取り付けられた枠部材60と、枠部材60の外側面に張り付けられた外装材61と、枠部材60の上面に固定された笠木62と、枠部材60の下面に固定された水切り63から構成されている。   The parapet structure 6 includes a frame member 60 attached around the roof structure 5, an exterior material 61 attached to the outer surface of the frame member 60, a headboard 62 fixed to the upper surface of the frame member 60, and a frame member 60. It is comprised from the drainer 63 fixed to the lower surface of this.

図6は、枠部材60を外壁構造3に隣接配置した部分に関する拡大断面図である。枠部材60は、波形鋼板50に固定された棒状の取付部材64により支持固定されている。取付部材64は、上述した長繊維補強硬化性樹脂発泡体からなり、波形鋼板50の上面に沿って所定間隔を空けて複数配置されている。取付部材64は、例えばその周囲を囲むように配置された固定具を波形鋼板50に固定することにより取り付けられる。外壁構造3の型枠ユニットパネル31には、取付部材64を挿通する挿通孔31aが穿設されており、取付部材64は、挿通孔31aを貫通して先端部が外方に突出し、枠部材60が突出した先端部に固定されている。   FIG. 6 is an enlarged cross-sectional view of a portion where the frame member 60 is disposed adjacent to the outer wall structure 3. The frame member 60 is supported and fixed by a rod-shaped attachment member 64 fixed to the corrugated steel plate 50. The attachment member 64 is made of the above-described long fiber reinforced curable resin foam, and a plurality of the attachment members 64 are arranged at predetermined intervals along the upper surface of the corrugated steel plate 50. The attachment member 64 is attached by, for example, fixing a fixture disposed so as to surround the periphery thereof to the corrugated steel plate 50. The formwork unit panel 31 of the outer wall structure 3 has an insertion hole 31a through which the attachment member 64 is inserted. The attachment member 64 penetrates the insertion hole 31a and protrudes outward from the frame member. 60 is fixed to the protruding tip.

取付部材64は、長繊維補強硬化性樹脂発泡体からなっているので、断熱性及び機械強度に優れており、パラペット構造6と外壁構造3との間の熱の移動を抑止するように作用する。また、外壁構造3の型枠ユニットパネル31の挿通孔31aに取付部材64が隙間なく接合しているので、接合部分を通した熱の移動を抑止でき、断熱効果を向上させることが可能となる。   Since the attachment member 64 is made of a long fiber reinforced curable resin foam, it is excellent in heat insulation and mechanical strength, and acts to suppress the movement of heat between the parapet structure 6 and the outer wall structure 3. . Moreover, since the attachment member 64 is joined to the insertion hole 31a of the formwork unit panel 31 of the outer wall structure 3 without a gap, it is possible to suppress the movement of heat through the joined portion and to improve the heat insulating effect. .

図7は、枠部材60を庇5aに隣接配置した部分に関する拡大断面図である。この場合にも庇5aに延設された波形鋼板50に取付部材64が支持固定される。取付部材64は、庇5aの側面に設けた断熱材52bに穿設された挿通孔を通して先端部が突出し、突出した先端部に枠部材60が固定される。そして、断熱材52bの挿通孔と取付部材64とを隙間なく接合することで断熱効果を向上させることができる。   FIG. 7 is an enlarged cross-sectional view of a portion where the frame member 60 is disposed adjacent to the flange 5a. Also in this case, the attachment member 64 is supported and fixed to the corrugated steel plate 50 extended to the flange 5a. The attachment member 64 has a distal end projecting through an insertion hole formed in the heat insulating material 52b provided on the side surface of the flange 5a, and the frame member 60 is fixed to the projected distal end. And the heat insulation effect can be improved by joining the penetration hole of the heat insulating material 52b, and the attachment member 64 without gap.

図8は、取付部材64の変形例を用いた構造に関する拡大断面図である。この例では、取付部材64は、金属製でL字状のアングル65を備えており、アングル65の建物内部に埋設される部分は断熱効果の大きい発泡樹脂材料からなる被覆部66で覆われている。そして、アングル65は、波形鋼板50に沿って配置されて取付具により固定されている。アングル65の折れ曲り部分65aは、外部に露出して枠部材60に固定されており、取付部材64により枠部材60が支持されるようになっている。   FIG. 8 is an enlarged cross-sectional view regarding a structure using a modification of the attachment member 64. In this example, the mounting member 64 has an L-shaped angle 65 made of metal, and a portion embedded in the building of the angle 65 is covered with a covering portion 66 made of a foamed resin material having a large heat insulating effect. Yes. And the angle 65 is arrange | positioned along the corrugated steel plate 50, and is being fixed with the fixture. The bent portion 65 a of the angle 65 is exposed to the outside and fixed to the frame member 60, and the frame member 60 is supported by the attachment member 64.

金属製のアングル65は熱伝導率が高いが、被覆部66により外壁構造3との間の熱の移動が抑止されるため、断熱効果を高めることができる。   Although the metal angle 65 has high thermal conductivity, the heat transfer between the outer wall structure 3 and the outer wall structure 3 is suppressed by the covering portion 66, so that the heat insulation effect can be enhanced.

なお、以上説明した例では、屋上構造に設けたパラペット構造について説明したが、ベランダ、バルコニー、外廊下といった構造に取り付けられるパラペット構造についても同様の断熱構造を構築することができる。   In the example described above, the parapet structure provided on the rooftop structure has been described. However, a similar heat insulating structure can be constructed for a parapet structure attached to a structure such as a veranda, a balcony, or an outer corridor.

上述した例では、屋上構造5に波形鋼板50を固定し、波形鋼板50に取付部材64を介してパラペット構造6を固定するようにしているが、屋上構造5を従来のコンクリートスラブ又は鉄骨梁の構造とすることもできる。図9は、こうした構造の屋上構造5’の断熱構造に関する概略断面図である。この例では、屋上構造5’は、コンクリートスラブ50’の上面に外壁構造から連続する断熱材51’及び遮熱シート52’が敷設されており、断熱材51’及び遮熱シート52’は、取付部材53’により取付部材36と同様に保持されている。遮熱シート52’の上部には、受け梁54’が架設されて取付部材53’においてネジ止めにより固定されている。そして、受け梁54’の上面に折版屋根構造55’が構築されている。また、受け梁54’は、端部を折り曲げてパラペット構造とすることもでき、端部に枠部材60を取り付けてパラペット構造を構築することもできる。   In the above-described example, the corrugated steel plate 50 is fixed to the rooftop structure 5, and the parapet structure 6 is fixed to the corrugated steel plate 50 via the attachment member 64. However, the rooftop structure 5 is made of a conventional concrete slab or steel beam. It can also be a structure. FIG. 9 is a schematic cross-sectional view regarding the heat insulating structure of the rooftop structure 5 ′ having such a structure. In this example, the rooftop structure 5 ′ has a heat insulating material 51 ′ and a heat insulating sheet 52 ′ continuous from the outer wall structure laid on the upper surface of the concrete slab 50 ′, and the heat insulating material 51 ′ and the heat insulating sheet 52 ′ are The mounting member 53 ′ holds the same as the mounting member 36. On the upper part of the heat shield sheet 52 ', a receiving beam 54' is installed and fixed to the mounting member 53 'by screws. A folded roof structure 55 'is constructed on the upper surface of the receiving beam 54'. Further, the receiving beam 54 ′ can be bent to have a parapet structure, and the frame member 60 can be attached to the end portion to construct a parapet structure.

屋上構造5’の周囲に形成されたパラペット構造6’は、断熱材51’及び遮熱シート52’から連続する断熱材及び遮熱シート並びに外壁構造から延設された断熱材及び遮熱シートにより全体が覆われている。したがって、屋上構造5’及びパラペット構造6’は、断熱材及び遮熱シートにより外部との間で熱的に遮断されるようになり、断熱効果を格段に向上させることができる。取付部材53’は、取付部材36と同様に上述した長繊維補強硬化性樹脂発泡体からなり、受け梁54’を支持するとともに断熱材51’の間に密着して取り付けられることで、断熱効果を高めることができる。   The parapet structure 6 ′ formed around the rooftop structure 5 ′ includes a heat insulating material and a heat insulating sheet continuous from the heat insulating material 51 ′ and the heat insulating sheet 52 ′, and a heat insulating material and a heat insulating sheet extending from the outer wall structure. The whole is covered. Therefore, the rooftop structure 5 ′ and the parapet structure 6 ′ are thermally shielded from the outside by the heat insulating material and the heat shielding sheet, and the heat insulating effect can be remarkably improved. The attachment member 53 ′ is made of the above-described long fiber reinforced curable resin foam like the attachment member 36, and supports the receiving beam 54 ′ and is attached in close contact between the heat insulating materials 51 ′. Can be increased.

A steel bundle 71 is erected on the bundle receiving beam 70, and the roof structure 7 is constructed above the steel bundle 71.

取付部材53’は、取付部材36と同様に上述した長繊維補強硬化性樹脂発泡体からなり、断熱材51’の間に密着した状態でコンクリートスラブ50’に取付部材36と同様に取付固定されている。取付部材53’は、鉄骨束71の下方に配置されて束受小梁70を支持固定しており、そのため、鉄骨束71を通じた熱橋現象は、取付部材53’により遮断することができ、断熱効果を高めることが可能となる。   The attachment member 53 ′ is made of the above-described long fiber reinforced curable resin foam like the attachment member 36, and is attached and fixed to the concrete slab 50 ′ in the same manner as the attachment member 36 while being in close contact with the heat insulating material 51 ′. ing. The attachment member 53 ′ is disposed below the steel bundle 71 to support and fix the bundle receiving beam 70, and therefore, the thermal bridge phenomenon through the steel bundle 71 can be blocked by the attachment member 53 ′. It becomes possible to enhance the heat insulation effect.

図11は、図10に示す屋上構造の変形例に関する概略断面図である。この例では、勾配のあるコンクリートスラブ50”の上面に断熱材51”及び遮熱シート52”が敷設され、遮熱シート52”の上部に母屋72が架設されて屋根構造7が構築されている。そして、母屋72の下部には、上述した長繊維補強硬化性樹脂発泡体からなる取付部材53”が配置されて取付部材53’と同様に支持固定するようになっている。そのため、母屋72を通じた熱橋現象は、取付部材53”により遮断することができ、断熱効果を高めることが可能となる。   FIG. 11 is a schematic cross-sectional view relating to a modified example of the roof structure shown in FIG. In this example, a heat insulating material 51 ″ and a heat insulating sheet 52 ″ are laid on the upper surface of a concrete slab 50 ″ having a gradient, and a roof 72 is constructed by laying a main building 72 above the heat insulating sheet 52 ″. . An attachment member 53 ″ made of the above-mentioned long fiber reinforced curable resin foam is disposed below the purlin 72, and is supported and fixed in the same manner as the attachment member 53 ′. The thermal bridge phenomenon can be blocked by the mounting member 53 ″, and the heat insulation effect can be enhanced.

図12は、既存の折版屋根構造に断熱構造を施工する場合の屋上構造に関する概略断面図である。既存の折版屋根構造8の上面には、断熱材80が取付部材82により保持されて面一に敷設されている。断熱材80の上面には遮熱シート81が覆うように敷き詰められている。そして、遮熱シート81の上部に受け梁83が架設されて取付部材82にネジ止めにより支持固定されている。そして、受け梁83の上面に新たな折版屋根84が取り付けられて、断熱構造を備えた新しい折版屋根構造8’が構築されている。この場合にも受け梁83は、上述した長繊維補強硬化性樹脂発泡体からなる取付部材82に支持されているので、受け梁83を通じた熱橋現象を取付部材82により遮断することができ、断熱効果を高めることが可能となる。   FIG. 12: is a schematic sectional drawing regarding the rooftop structure in the case of constructing a heat insulation structure in the existing folded roof structure.

Then, a new folded roof 84 is attached to the upper surface of the receiving beam 83, and a new folded roof structure 8 'having a heat insulating structure is constructed. Also in this case, since the receiving beam 83 is supported by the mounting member 82 made of the above-described long fiber reinforced curable resin foam, the mounting member 82 can block the thermal bridge phenomenon through the receiving beam 83, It becomes possible to enhance the heat insulation effect.
