Description

本発明は、施工性が高くかつエネルギー効率のよい住宅の天井の断熱構造に関する。   The present invention relates to a heat insulating structure for a ceiling of a house having high workability and high energy efficiency.

従来より、住宅等の建築物には、屋内で冷暖房等を使用する際に、室内の熱が漏れたり外気が屋内に出入したりすることによるエネルギーロスを抑えて住空間の快適性が得られるよう、天井、床、外壁等に断熱材や気密材が施工されている。
住宅のエネルギー効率を高めるには、一般的に、天井、外壁及び床等に断熱材を配するとともに、断熱材同士等の間隙を埋め断熱及び気密化が図られていない箇所をなくす必要があるが、天井部への断熱材の施工は、高所での施工となる上、下地材となるものとして野縁等が組まれているのみであるため、様々な施工方法が開発されている(例えば下記特許文献1)。
Conventionally, in buildings such as houses, when using air conditioning indoors, the comfort of living space can be obtained by suppressing energy loss due to indoor heat leaks and outside air entering and exiting indoors. Insulation materials and airtight materials are installed on ceilings, floors, and outer walls.
In order to increase the energy efficiency of a house, it is generally necessary to arrange heat insulating materials on the ceiling, outer walls, floors, etc., and eliminate gaps between the heat insulating materials and the like that are not insulated and airtight. However, the construction of the heat insulating material on the ceiling part is done at a high place, and since only the edge is built as a base material, various construction methods have been developed ( For example, the following patent document 1).

下記特許文献1に記載の天井の断熱構造では、天井における小屋梁の下方の野縁上に天井断熱材が天井全体に亘って敷設され、野縁下面に天井気密シート材が所定の間隔でタッカーにより固定された状態で貼り付けられている。更に、天井気密シート材の下面には、気密層及び天井面材として天井下地材が連続的に設けられ、その下方に天井仕上げ材が固定されている。そして、天井面材及び外壁等との取合い部は、隙間充填体で覆う構造とされている。
このような構造を採用することにより、「木造建築物の気密性の向上を図りつつ、シート材同士の端部をオーバーラップさせて連続する作業や、テープ等で躯体の隙間を埋める作業を不要として、気密構造の施工性を向上させ、不慣れな作業者でも気密構造の施工を容易に行うことができ、延いては気密構造を有する木造建築物の温暖地域での普及性の向上を図ることができる」としている。
In the heat insulating structure of the ceiling described in Patent Document 1 below, a ceiling heat insulating material is laid over the entire ceiling on the lower edge of the roof beam on the ceiling, and the ceiling airtight sheet material is tucked at a predetermined interval on the lower surface of the field edge. It is pasted in a fixed state. Further, a ceiling base material is continuously provided as an airtight layer and a ceiling surface material on the lower surface of the ceiling airtight sheet material, and a ceiling finishing material is fixed below the ceiling base material. And the joint part with a ceiling surface material, an outer wall, etc. is set as the structure covered with a clearance gap filling body.
By adopting such a structure, it is possible to improve the airtightness of the wooden building, while eliminating the need for continuous work by overlapping the ends of the sheet materials and filling the gaps in the housing with tape etc. To improve the workability of the airtight structure, even an unskilled worker can easily perform the work of the airtight structure, and to improve the spread of the wooden building with the airtight structure in the warm area. Is possible. "

しかし、上記断熱構造によれば、所定の間隔で高所に多数配置された複数の野縁の間からその上部に天井断熱材を通し入れて、これらの複数の野縁上に配置しなければならないため、施工作業が煩雑かつ困難であるという問題があった。
しかも、高所に組まれた複数の野縁上に、天井全体に亘って隙間なく天井断熱材及び天井気密シートを敷設し固定するには、経験に基づく一定の習熟が必要であり、不慣れな作業者が容易に施工できるというものではなかった。
また、野縁上に敷き込む天井断熱材が、ガラスウール,ロックウール又はウレタン等により形成されているものであるため、野縁上で徒に嵩張り、野縁と屋根との間のスペース(いわゆる屋根裏)を有効活用し難いという問題があった。
また更に、嵩張りやすいガラスウール等を天井全体に配するものであるため、施工現場に大量のガラスウール等を運搬しなければならず、また、天井断熱材のための置き場に多くのスペースが取られ、円滑な施工作業の妨げになるという問題があった。
本発明は、上記課題に鑑み、施工性が高くかつエネルギー効率のよい住宅の天井の断熱構造を提供することを課題とする。

The hermetic tape 4 is formed to a thickness of 2 mm by a polyethylene foam resin sheet having a foaming ratio of 20 times, and a double-sided tape is attached in advance to the front and back surfaces of the hermetic tape 4.

断熱ボード5は、天井パネル2と略同寸法で矩形に形成されたボード状の部材であり、材料としては特に限定されないが、例えば、ポリスチレン,ポリエチレン,フェノール,硬質ウレタン等の弾性変形して圧縮可能な発泡樹脂材料により形成されている。より具体的には、例えば、「省エネルギー対策等級4 技術基準」表3−1「断熱材の種類一覧」で示された、A種ビーズ法ポリスチレンフォーム保温板1〜4号、A種ポリエチレンフォーム保温板1種1号,2号,2種,3種、A種押出法ポリスチレンフォーム保温板1種〜3種、A種フェノールフォーム保温板1種2号,2種1号,2号,2種3号,3種1号,2号、A種ビーズ法ポリスチレンフォーム保温板特号,A種硬質ウレタンフォーム保温板1種,2種1号〜4号等を用いることができる。

The heat insulation board 5 is a board-like member formed in a rectangular shape with substantially the same dimensions as the ceiling panel 2 and is not particularly limited as a material. For example, the heat insulation board 5 is compressed by elastic deformation such as polystyrene, polyethylene, phenol, and hard urethane. It is formed of a possible foamed resin material. More specifically, for example, A-type bead method polystyrene foam heat insulating plates 1 to 4 and A-type polyethylene foam heat insulating materials shown in “Energy Saving Countermeasure 4 Technical Standards” Table 3-1 “List of Types of Insulating Materials” 1 type, 2 type, 2 type, 3 type plate, A type extrusion method polystyrene foam heat insulating plate type 1 to 3 type, A type phenol foam heat insulating plate type 1 type 2, 2 type 1, No. 2, type 2 type No. 3, No. 3, No. 1, No. 2, Type A bead method polystyrene foam heat insulating plate, No. A type hard urethane foam heat insulating plate, No. 2, No. 1 to No. 4 can be used.
In addition, since the heat insulation board 5 is formed of a foamed resin material that can be elastically deformed and compressed, a projection when an adhesive such as adhesive or dust adheres to the field edge 3, or some of the field edge 3. Steps and the like are effectively absorbed by the heat insulating board 5 being elastically deformed and compressed.

断熱ボード5の厚さ寸法は、10mm〜150mmとするのが好ましく、20mm〜100mmとするのが更に好ましい。
図3に示すように、断熱ボード5は、その下面5aに天井パネル2の上面2aを貼り合わせ、その上面5bを野縁3の下面3aの気密テープ4に密着させて固定されている。
The thickness dimension of the heat insulating board 5 is preferably 10 mm to 150 mm, and more preferably 20 mm to 100 mm.
As shown in FIG. 3, the heat insulating board 5 is fixed with the upper surface 2 a of the ceiling panel 2 bonded to the lower surface 5 a and the upper surface 5 b in close contact with the airtight tape 4 on the lower surface 3 a of the field edge 3.

天井パネル2は、石膏等を芯材としてこの芯材の表面をパネル用の厚紙で被覆し、更にクロスを貼り付け天井最下面に配される仕上げ用の板状部材であり、断熱ボード5と略同寸法の長方形に切り出されたものである。
天井パネル2の厚さ寸法は、特に制限はないが、3mm〜50mmとするのが好ましく、5mm〜30mmとするのが更に好ましい。
かかる天井パネル2は、図1に示すように、例えば釘等の固定部材20により、長手方向に延在する端部2c,2cを、断熱ボード5を介して野縁3,3の下面3aに固定されている。
The ceiling panel 2 is a plate-like member for finishing that is coated on the bottom surface of the ceiling by covering the surface of the core material with a cardboard for the panel using plaster as a core material, and further attaching a cloth. It is cut out into a rectangle of approximately the same dimensions.
The thickness dimension of the ceiling panel 2 is not particularly limited, but is preferably 3 mm to 50 mm, and more preferably 5 mm to 30 mm.
As shown in FIG. 1, the ceiling panel 2 has end portions 2 c and 2 c extending in the longitudinal direction by a fixing member 20 such as a nail, for example, on a lower surface 3 a of the field edges 3 and 3 via a heat insulating board 5. It is fixed.

第1の補強シート7は、野縁3,3に固定された断熱ボード5及び天井パネル2を野縁3に直交する方向(野縁3,3間に跨る方向)に保持してこれら断熱ボード5及び天井パネル2を支持する帯状に形成された部材である。
第1の補強シート7の材質としては、例えば、ポリプロピレン,塩化ビニル樹脂,塩化ビニリデン樹脂,酢酸ビニル樹脂,ポリビニルアルコール,ポリビニルアセタール,ポリスチレン,AS樹脂,ABS樹脂,メタクリル樹脂,ポリエチレン,フッ素樹脂,ポリアミド,ポリアセタール,ポリカーボネート,ポリスルホン等の単体もしくはこれらの複合物よりなる合成樹脂材料、ガラス繊維強化プラスチック,炭素繊維強化プラスチック,アラミド繊維強化プラスチック等の樹脂材料に繊維系材料を混入させた複合材料、又は炭素鋼,ステンレス鋼,クロム鋼,マンガン鋼,ニッケルクロム鋼,ニッケルマンガン鋼等を備えてなる金属材料等の耐久性及び剛性を有するものが挙げられる。特に、金属材料の場合は、ステンレス鋼のような錆びにくい材料が用いられるか、塗装、メッキなどの防錆処理がなされていることが好ましい。
第1の補強シート7の厚さ寸法は、0.2mm〜5mmとされていることが好ましく、0.3mm〜3mmとされていることが更に好ましい。第1の補強シート7の厚さ寸法が0.2mmより小さい場合、第1の補強シート7は、断熱ボード5の弛み及び歪みを防止し得る強度及び曲げ剛性を担保することが困難となり、同厚さ寸法が5mmより大きい場合、この第1の補強シート7の厚みが野縁3の下面3a側に配された断熱ボード5にひびく可能性があり、第1の補強シート7が配された位置で断熱ボード5を隆起させて表面が歪な形状なったり断熱ボード5,5同士の間で隙間が形成されたりすることが考えられる。
The first reinforcing sheet 7 holds the heat insulation board 5 and the ceiling panel 2 fixed to the field edges 3 and 3 in a direction perpendicular to the field edge 3 (a direction straddling the field edges 3 and 3). 5 and a band-shaped member that supports the ceiling panel 2.
Examples of the material of the first reinforcing sheet 7 include polypropylene, vinyl chloride resin, vinylidene chloride resin, vinyl acetate resin, polyvinyl alcohol, polyvinyl acetal, polystyrene, AS resin, ABS resin, methacrylic resin, polyethylene, fluorine resin, and polyamide. , A synthetic resin material made of a simple substance such as polyacetal, polycarbonate, polysulfone, or a composite thereof, a composite material obtained by mixing a fiber material into a resin material such as a glass fiber reinforced plastic, a carbon fiber reinforced plastic, or an aramid fiber reinforced plastic, or Examples include those having durability and rigidity, such as metal materials including carbon steel, stainless steel, chromium steel, manganese steel, nickel chromium steel, nickel manganese steel, and the like. In particular, in the case of a metal material, it is preferable that a rust-resistant material such as stainless steel is used, or that rust prevention treatment such as painting or plating is performed.
The thickness of the first reinforcing sheet 7 is preferably 0.2 mm to 5 mm, and more preferably 0.3 mm to 3 mm. When the thickness dimension of the first reinforcing sheet 7 is smaller than 0.2 mm, it becomes difficult for the first reinforcing sheet 7 to ensure strength and bending rigidity that can prevent the slack and distortion of the heat insulating board 5. If the thickness dimension is larger than 5 mm, the thickness of the first reinforcing sheet 7 may crack on the heat insulating board 5 disposed on the lower surface 3a side of the field edge 3, and the first reinforcing sheet 7 is disposed. It is conceivable that the heat insulating board 5 is raised at the position so that the surface has a distorted shape or a gap is formed between the heat insulating boards 5 and 5.

図2,図3に示すように、第1の補強シート7は、隣接する野縁3,3の間に跨るように、所定の間隔をおいて複数平行に配置され、野縁3,3の下面3aに対向する板面に両面テープt1を貼着し該気密テープ4の表面に貼着されている。第1の補強シート7の下方を向く板面には、両面テープt2を貼着し、この両面テープt2によって断熱ボード5の短手方向に延在する端部(断熱ボード5の野縁3,3間に跨る方向に延在する端部)の上面5bを貼り合わせて保持固定している。   As shown in FIGS. 2 and 3, the first reinforcing sheets 7 are arranged in parallel at a predetermined interval so as to straddle between the adjacent field edges 3 and 3. A double-faced tape t1 is attached to the plate surface facing the lower surface 3a and is attached to the surface of the airtight tape 4. A double-faced tape t2 is attached to the plate surface facing the lower side of the first reinforcing sheet 7, and an end portion extending in the short direction of the heat-insulating board 5 by the double-sided tape t2 (the field edge 3 of the heat-insulating board 5). The upper surface 5b of the end portion extending in the direction extending between the three is bonded and held and fixed.

図3に示すように、気密保持部材8は、野縁3,3に隣接配置される断熱ボード5,5の野縁3,3間に跨る方向(紙面奥行き方向)に延在する端面15,15同士の間に挟持され、該端面15,15間の気密性を持たせる部材であり、発泡倍率が5倍〜50倍のポリエチレン等を材料とする発泡性樹脂により形成されている。
気密保持部材8の板面の寸法は、図1に示すように、長手方向の寸法L1が断熱ボード5の野縁3,3間に跨る方向に延在する端部の長さを有し、短手方向の寸法L2が断熱ボード5の厚さ寸法と同寸法か、この厚さ寸法よりも小寸法とされている。気密保持部材8の厚さ寸法は、1mm〜20mmであればよく、2mm〜10mmとされていると更に好ましい。
As shown in FIG. 3, the airtight holding member 8 includes end faces 15 extending in a direction (depth direction in the drawing) between the field edges 3 and 3 of the heat insulating boards 5 and 5 disposed adjacent to the field edges 3 and 3. It is a member that is sandwiched between 15 and imparts airtightness between the end faces 15 and 15 and is made of a foamable resin made of polyethylene having a foaming ratio of 5 to 50 times.
As shown in FIG. 1, the dimension of the plate surface of the airtight holding member 8 has the length of the end portion in which the dimension L1 in the longitudinal direction extends in the direction straddling between the field edges 3 and 3 of the heat insulating board 5; The dimension L2 in the short direction is the same as the thickness dimension of the heat insulating board 5 or smaller than this thickness dimension. The thickness dimension of the airtight holding member 8 may be 1 mm to 20 mm, and more preferably 2 mm to 10 mm.

上記の構成の下に、第1の補強シート7と気密保持部材8とは、図4に示すように、長手方向に延在する各一端縁7m,8mにおいて両面テープt1により略垂直に連結され、断熱ボード5の端部に配される端部部材9を構成している。なお、両面テープt1は、第1の補強シート7の板面全体を覆うものであってもよい。   Under the above-described configuration, the first reinforcing sheet 7 and the airtight holding member 8 are connected substantially vertically by the double-sided tape t1 at each end edge 7m, 8m extending in the longitudinal direction, as shown in FIG. The end member 9 disposed at the end of the heat insulating board 5 is configured. The double-sided tape t1 may cover the entire plate surface of the first reinforcing sheet 7.

次に、端部部材9の作製方法と天井の断熱構造1の施工方法について説明する。
天井の断熱構造1の施工に際しては、まず、断熱ボード5及び天井パネル2の固定に用いられる端部部材9を用意しておく。
端部部材9の作製は、図5(a)に示す第1の補強シート7に、同図(b)に示すように第1の補強シート7の長手方向に延在する端縁7mに沿って両面テープt1を貼着する。この際、両面テープt1の長手方向に延在する端縁sが第1の補強シート7から突出するように配置する。そして、同図(c)に示すように、第1の補強シート7の板面7aに対して気密保持部材8の板面8aが垂直に立ち上がるように気密保持部材8の端面を両面テープt1に貼着し、断面が略逆L字状になるように端部部材9を形成する。
Next, a manufacturing method of the end member 9 and a construction method of the ceiling heat insulating structure 1 will be described.
When constructing the ceiling heat insulating structure 1, first, an end member 9 used for fixing the heat insulating board 5 and the ceiling panel 2 is prepared.
The end member 9 is manufactured along the edge 7m extending in the longitudinal direction of the first reinforcing sheet 7 as shown in FIG. 5B, on the first reinforcing sheet 7 shown in FIG. And attach the double-sided tape t1. At this time, the double-sided tape t <b> 1 is arranged so that the edge s extending in the longitudinal direction protrudes from the first reinforcing sheet 7. Then, as shown in FIG. 4C, the end surface of the airtight holding member 8 is attached to the double-faced tape t1 so that the plate surface 8a of the airtight holding member 8 rises perpendicularly to the plate surface 7a of the first reinforcing sheet 7. The end member 9 is formed so that the cross section is substantially inverted L-shaped.

一方、野縁3には、図6(a)に示すように、まずその下面3a全体を覆うように気密テープ4を貼着しておく。
そして、同図(b)に示すように、予め作製しておいた端部部材9を、所定の間隔、具体的には、一の断熱ボード5の長手方向に延在する端部の寸法(すなわち野縁3の延在方向に沿う端部の長さ寸法)と同寸法又は僅かに短い間隔を置いて、野縁3,3に跨ってこれら野縁3,3の延在する方向に直交するように配置し固定していく。同図(c)は、端部部材9が配置された状態を側断面視した図である。
On the other hand, as shown in FIG. 6A, an airtight tape 4 is first attached to the field edge 3 so as to cover the entire lower surface 3a.
And as shown in the figure (b), the edge part member 9 produced beforehand is made into the predetermined space | interval, specifically, the dimension (the dimension of the edge part extended in the longitudinal direction of the one heat insulation board 5 ( That is, the same length as the end portion along the extending direction of the field edge 3 or a slightly shorter interval, and the field edges 3, 3 extending across the field edges 3, 3 perpendicular to the extending direction. Place and fix as you do. FIG. 3C is a side sectional view showing a state where the end member 9 is arranged.

端部部材9を上記のように設置していくと、図6(b)に示すように、野縁3,3と端部部材9,9とによって断熱ボード5を固定する下地となる矩形の枠Wが形成される。そこで、この枠Wに予め天井パネル2が貼り合わされた単位断熱ボード5を順次当接させ、図7(a)に示すように、第1の補強シート7の下方の位置で天井パネル2を上方に押圧し、第1の補強シート7に断熱ボード5を確実に貼着する。この際、端部部材9,9・・は、一の断熱ボード5の長手方向に延在する端部の寸法と同寸法又は僅かに短い間隔を置いて配置されているため、気密保持部材8を挟んで隣接する断熱ボード5,5は、気密保持部材8に対して付勢しつつこの気密保持部材8を隙間なく密に挟持して配置される。そして更に、同図(b)に示すように、野縁3に対向する天井パネル2及び断熱ボード5の端部を釘等の固定部材20により、これら天井パネル2及び断熱ボード5を天井部に固定して、天井の断熱構造1の施工が完了する。なお、固定部材20としては、釘、ボルトや木ねじ等が挙げられるが、固定部材20を用いずに、接着剤や嵌合等により固定されてもよい。   When the end member 9 is installed as described above, as shown in FIG. 6B, a rectangular shape serving as a base for fixing the heat insulating board 5 by the field edges 3 and 3 and the end members 9 and 9 is provided. A frame W is formed. Therefore, the unit heat insulation board 5 on which the ceiling panel 2 is bonded in advance is sequentially brought into contact with the frame W, and the ceiling panel 2 is moved upward at a position below the first reinforcing sheet 7 as shown in FIG. The heat insulation board 5 is securely adhered to the first reinforcing sheet 7. At this time, the end members 9, 9... Are arranged at the same size as the end portion extending in the longitudinal direction of the one heat insulating board 5 or at a slightly shorter interval. The heat insulating boards 5 and 5 adjacent to each other are arranged so as to sandwich the airtight holding member 8 tightly without any gap while urging the airtight holding member 8. Further, as shown in FIG. 4B, the ceiling panel 2 and the heat insulation board 5 facing the field edge 3 are fixed to the ceiling portion 2 by a fixing member 20 such as a nail. After fixing, the construction of the heat insulating structure 1 on the ceiling is completed. The fixing member 20 may be a nail, a bolt, a wood screw, or the like, but may be fixed by an adhesive or fitting without using the fixing member 20.

このようにして、天井の全体に断熱ボード5が配され、断熱ボード5,5同士の間に隙間が形成され得る野縁3,3の延在方向には気密テープ4が配され、野縁3の延在方向に直交する端面15,15同士の間には気密保持部材8が配され、断熱ボード5,5がこの気密保持部材8に付勢しつつ密着して固定されて、天井全体において隙間なく気密材及び断熱材を配することができ、気密性及び断熱性の高い天井の構造1が形成される。   In this way, the heat insulation board 5 is arranged on the entire ceiling, and the airtight tape 4 is arranged in the extending direction of the field edges 3 and 3 where a gap can be formed between the heat insulation boards 5 and 5. 3 is provided between the end faces 15 and 15 orthogonal to the extending direction of the airtight member 3, and the heat insulating boards 5 and 5 are fixed in close contact with the airtight holding member 8 while being urged. Thus, the airtight material and the heat insulating material can be disposed without any gaps, and the ceiling structure 1 having high airtightness and heat insulating properties is formed.

以上のように、天井の断熱構造1によれば、断熱ボード5を野縁3の下面3a側に貼着し固定する構成とされているため、断熱ボード5の敷設を簡便に行うことができる。また、断熱材がボード状に形成されたものであるため、天井全体に亘って一定の厚さをもって水平に隙間なく貼着することが容易となる。   As described above, according to the heat insulating structure 1 for the ceiling, the heat insulating board 5 is attached to the lower surface 3a side of the field edge 3 and fixed, so that the heat insulating board 5 can be laid easily. . In addition, since the heat insulating material is formed in a board shape, it is easy to apply a uniform thickness across the entire ceiling without gaps.

また、隣接する野縁3,3と、野縁3,3間に跨ってそれらの下面3aに配された第1の補強シート7,7とにより形成された枠Wに断熱ボード5及び天井パネル2を当接させて敷設することができるため、断熱ボード5の敷設が容易であるとともに、断熱ボード5を気密保持部材8に付勢して密着させ、野縁3,3間方向に弛みなく気密性をもって敷設することができる。また、断熱ボード5の敷設後も、第1の補強シート7により、断熱ボード5を弛みなく支持することができ、高い断熱性及び気密性を得ることができる。   Further, the heat insulation board 5 and the ceiling panel are formed on the frame W formed by the adjacent field edges 3 and 3 and the first reinforcing sheets 7 and 7 disposed on the lower surface 3a across the field edges 3 and 3. 2 can be installed in contact with each other, so that it is easy to install the heat insulation board 5 and the heat insulation board 5 is urged and brought into close contact with the airtight holding member 8 so that it does not loosen in the direction between the field edges 3 and 3. It can be laid with airtightness. Further, even after the heat insulation board 5 is laid, the first reinforcement sheet 7 can support the heat insulation board 5 without slack, and high heat insulation and airtightness can be obtained.

また、断熱ボード5は、野縁3の下面3aに配するため、野縁3と屋根との間のスペースを占有することなく、このスペースを有効に活用することが可能となる。
また更に、断熱ボード5は、ガラスウール等のように嵩張らず、一定の厚さに形成され、1のボードが所定の板面積となるようにカットしておくことが可能であるため、施工に際して断熱ボード5を現場へ運搬する場合に、断熱ボード5を重ねてコンパクトにすることができ、また、現場での施工時にも断熱ボード5をコンパクトにまとめて場所をとらずに載置しておくことができる。
Moreover, since the heat insulation board 5 is arranged on the lower surface 3a of the field edge 3, this space can be effectively utilized without occupying the space between the field edge 3 and the roof.
Furthermore, the heat insulating board 5 is not bulky like glass wool, and is formed in a certain thickness, and can be cut so that one board has a predetermined plate area. When transporting the heat insulation board 5 to the site, the heat insulation board 5 can be stacked to be compact, and the heat insulation board 5 can be compactly placed and placed without taking up any place during construction at the site. be able to.

また更に、第1の補強シート7が薄肉のシート状に形成されたものであり、かつ、断熱ボード5が弾性変形して圧縮可能な発泡樹脂製材料により形成されているため、この第1の補強シート7の厚みが野縁3の下面3a側に配された断熱ボード5にひびき難い。また第1の補強シート7の厚さであれば、断熱ボード5の厚さに吸収され得るため、第1の補強シート7が配された位置で断熱パネル5を隆起させて表面が歪な形状とし、断熱ボード5,5同士の間に隙間を形成することを防止することができる。   Furthermore, since the first reinforcing sheet 7 is formed in a thin sheet shape, and the heat insulating board 5 is formed of a foamed resin material that can be elastically deformed and compressed, the first reinforcing sheet 7 is formed. The thickness of the reinforcing sheet 7 is difficult to crack the heat insulating board 5 arranged on the lower surface 3a side of the field edge 3. Further, since the thickness of the first reinforcing sheet 7 can be absorbed by the thickness of the heat insulating board 5, the heat insulating panel 5 is raised at the position where the first reinforcing sheet 7 is disposed, and the surface is distorted. And forming a gap between the heat insulating boards 5 and 5 can be prevented.

また、第1の補強シート7が、耐久性及び剛性を有する材質で形成されているため、軽量で、シート状でありながら確実かつ長期に亘り断熱ボード5を確実に支持することができる。
また、第1の補強シート7が一の断熱ボード5の野縁3,3間に跨る方向に延在する端部の上面5bに沿って配置されているため、この一の単位断熱ボード5の端部を弛ませないよう水平に支持し、隣接する他の単位断熱ボード5との隙間の形成を防止することができる。
Moreover, since the 1st reinforcement sheet | seat 7 is formed with the material which has durability and rigidity, it can support the heat insulation board 5 reliably for a long time, being lightweight and sheet-like.
Moreover, since the 1st reinforcement sheet 7 is arrange | positioned along the upper surface 5b of the edge part extended in the direction straddling between the field edges 3 and 3 of the one heat insulation board 5, of this one unit heat insulation board 5 It can support horizontally so that an end may not be slackened, and it can prevent formation of a crevice between other unit heat insulation boards 5 which adjoin.

上記の実施態様において、天井の断熱構造1の端部部材9は、第1の補強シート7を野縁3の下面3aと前記断熱ボード5の上面5bとの間にのみ配置する構成としたが、図8に示すように、第1の補強シート7と同材料からなる第2の補強シート10が第1の補強シート7に垂直に立ち上がるように気密保持部材8の板面に貼着された構成であってもよい。この場合、第1の補強シート7と第2の補強シート10とは互いに分離したものであっても、一体的に連設されたものであってもよい。
このような構成とすることで、端部部材9ひいては端部部材9に貼着する断熱ボード5の端部の剛性をより一層高めることができるという効果が得られる。
In the above embodiment, the end member 9 of the heat insulating structure 1 for the ceiling is configured such that the first reinforcing sheet 7 is disposed only between the lower surface 3 a of the field edge 3 and the upper surface 5 b of the heat insulating board 5. As shown in FIG. 8, the second reinforcing sheet 10 made of the same material as that of the first reinforcing sheet 7 is stuck to the plate surface of the airtight holding member 8 so as to rise vertically to the first reinforcing sheet 7. It may be a configuration. In this case, the first reinforcing sheet 7 and the second reinforcing sheet 10 may be separated from each other or may be integrally connected.
By setting it as such a structure, the effect that the rigidity of the edge part 9 and by extension, the edge part of the heat insulation board 5 stuck to the edge member 9 can be improved further is acquired.

又は、第1の補強シート7は、図9に示すように、気密保持部材8を挟んで両側方に隣接配置される断熱ボード5,5の双方を保持固定するものであってもよい。
かかる構成とすることで、断熱ボード5の野縁3,3間に跨る方向に延在する両端部をより一層確実に保持することができるという効果が得られる。
なお、本願発明は、木造住宅での天井の下地である野縁3に施工する天井の断熱構造1を例として述べたが、鉄骨造や鉄筋コンクリート造などの住宅での天井の下地であるLGS(ライトゲージスタッド)にも適用してもよい。
Or the 1st reinforcement sheet | seat 7 may hold | maintain and fix both the heat insulation boards 5 and 5 arrange | positioned adjacent to both sides on both sides of the airtight holding member 8, as shown in FIG.
By setting it as this structure, the effect that the both ends extended in the direction straddling between the field edges 3 and 3 of the heat insulation board 5 can be hold | maintained more reliably is acquired.
In the present invention, the ceiling heat insulating structure 1 to be constructed on the field edge 3 which is the base of the ceiling in the wooden house has been described as an example, but LGS (LGS ( You may apply also to a light gauge stud.
