Description

本発明は、建築物の断熱構造及びその施工方法に関し、さらに詳細には、外壁と連続する床スラブを断熱する断熱構造及びその施工方法に関する。 The present invention relates to a heat insulating structure of a building and a construction method thereof, and more particularly to a heat insulating structure for insulating a floor slab continuous with an outer wall and a construction method thereof.

コンクリート造りの住宅等の建築物においては、省エネルギー性能を確保するために外気と接する外壁部だけでなく、外壁部と連続する仕切り壁、スラブの天井面（下面）や床面(上面)に熱橋を防止する断熱補強が行なわれる。
例えば特許文献１に記載された断熱補強構造は、床スラブの上面において外壁部に断熱ボードを当接させた状態とし、床スラブの上面をセルフレベリング材で被覆し、ボード状断熱材を接着して所定位置に固定し、その上に再度セルフレベリング材を施工し養生し、硬化させてフローリング材の下地とする。ボード状断熱材の外周部と外壁部との間には、発泡ウレタン断熱材を吹き付けて断熱するようにしている。 In buildings such as concrete houses, heat is applied not only to the outer wall that comes into contact with the outside air, but also to the partition wall that is continuous with the outer wall, and the ceiling surface (lower surface) and floor surface (upper surface) of the slab in order to ensure energy saving performance. Insulation reinforcement is provided to prevent the bridge.
For example, in the heat insulating reinforcement structure described in Patent Document 1, the heat insulating board is brought into contact with the outer wall portion on the upper surface of the floor slab, the upper surface of the floor slab is covered with a self-leveling material, and the board-shaped heat insulating material is adhered. After fixing it in a predetermined position, a self-leveling material is applied again on it, cured, and cured to form a base for the flooring material. A urethane foam heat insulating material is sprayed between the outer peripheral portion and the outer wall portion of the board-shaped heat insulating material to insulate.

特開２００４－３６０２７８号公報Japanese Unexamined Patent Publication No. 2004-360278

特許文献１に開示された断熱補強構造は、床スラブの上面にセルフレベリング材を流し込み、その上にボード状断熱材を敷き込み、セルフレベリング材の硬化によりボード状断熱材を固定するようにしたり、セルフレベリング材が硬化した後接着剤で固定するようにしているが、セルフレベリング材の上にボード状断熱材を敷き込んだだけでは、床スラブの不陸の影響やボード状断熱材の反りやねじれの影響で底面全体が密着する状態とならず、空気の巻き込みや浮上がりなどが生じる。これにより、ボード状断熱材に浮きやセルフレベリング材からの剥がれが生じ、それによりセルフレベリング材にクラックが発生したり、床の遮音性能の低下原因となるなどの問題がある。 In the heat insulating and reinforcing structure disclosed in Patent Document 1, a self-leveling material is poured on the upper surface of the floor slab, a board-shaped heat insulating material is laid on the self-leveling material, and the board-shaped heat insulating material is fixed by curing the self-leveling material. After the self-leveling material has hardened, it is fixed with an adhesive, but if the board-shaped heat insulating material is simply laid on the self-leveling material, the floor slab will not be affected and the board-shaped heat insulating material will warp. Due to the influence of twisting and twisting, the entire bottom surface does not come into close contact with each other, causing air entrainment and floating. This causes the board-shaped heat insulating material to float or peel off from the self-leveling material, which causes problems such as cracks in the self-leveling material and deterioration of the sound insulation performance of the floor.

本発明は、かかる問題点に鑑みてなされたものであり、ボード状断熱材を床スラブに密着させて取り付けることができ、セルフレベリング材のクラックの発生や床の遮音性能の低下を抑制することができる建築物の断熱構造及びその施工方法を提供することを目的とする。 The present invention has been made in view of the above problems, and the board-shaped heat insulating material can be attached in close contact with the floor slab, and cracks in the self-leveling material and deterioration of the sound insulation performance of the floor can be suppressed. It is an object of the present invention to provide a heat insulating structure of a building and a construction method thereof.

以下、本発明の建築物の断熱構造及びその施工方法の一実施の形態について、図面を参照して詳細に説明する。
本発明の建築物の断熱構造１は、コンクリート造りの床スラブ１０と、床スラブ１０に立設されるコンクリート造りの外壁部２０と、床スラブ１０上に設けられるボード状断熱材３０と、床スラブ１０上に設けられボード状断熱材３０の底面３１及び隣接するボード状断熱材３０との間の目地部を除く小口面３２の中間部まで埋設させて固定する第１のセルフレベリング材４０と、ボード状断熱材３０及び第１のセルフレベリング材４０上に設けられ外壁部２０を断熱する外壁部断熱材５０と、第１のセルフレベリング材４０に埋設されて固定されたボード状断熱材３０の上面３３を覆って設けられる第２のセルフレベリング材６０と、を備えて構成される。なお、第２のセルフレベリング材６０上には、床仕上げ材７０が接着などで設けられる。 Hereinafter, an embodiment of the heat insulating structure of the building and the construction method thereof of the present invention will be described in detail with reference to the drawings.
The heat insulating structure 1 of the building of the present invention includes a concrete floor slab 10, a concrete outer wall portion 20 erected on the floor slab 10, a board-shaped heat insulating material 30 provided on the floor slab 10, and a floor. With the first self-leveling material 40 provided on the slab 10 and fixed by burying up to the middle portion of the fore-edge surface 32 excluding the joint portion between the bottom surface 31 of the board-shaped heat insulating material 30 and the adjacent board-shaped heat insulating material 30. , The outer wall heat insulating material 50 provided on the board-shaped heat insulating material 30 and the first self-leveling material 40 to insulate the outer wall portion 20, and the board-shaped heat insulating material 30 embedded and fixed in the first self-leveling material 40. A second self-leveling material 60 provided so as to cover the upper surface 33 of the above surface 33 is provided. A floor finishing material 70 is provided on the second self-leveling material 60 by adhesion or the like.

また、本発明の建築物の断熱構造の施工方法では、建築物の断熱構造１を施工するに際し、第１のセルフレベリング材４０に埋設固定されるボード状断熱材３０は、第１のセルフレベリング材４０が流動性のある状態で敷き込んでボード面（底面３１及び上面３３）３１，３３に平行に移動させながら小口面３２の中間部まで埋設するようにする。
これにより、ボード状断熱材３０の敷き込み時に、単に第１のセルフレベリング材４０の上に敷き並べるのではなく、ボード状断熱材３０を少し前後左右方向にボード面３１，３３と平行に動かしながら、第１のセルフレベリング材４０に押し付け１ｍｍからボード状断熱材３０厚さの２／３程度まで沈めるようにして、ボード状断熱材３０と第１のセルフレベリング材４０の間の空気を抜き、浮き上がりをなくして密着させるようにする。また、ボード状断熱材３０の小口面３２部分に第１のセルフレベリング材４０が廻り込むことでボード状断熱材３０の底面３１だけでなく、小口面３２も接着面としてしっかりと接着固定することで、剥がれにつながる衝撃力に対するボード状断熱材３０の密着力や固定力の向上を図るようにする。 Further, in the method for constructing the heat insulating structure of a building of the present invention, when the heat insulating structure 1 of the building is constructed, the board-shaped heat insulating material 30 buried and fixed in the first self-leveling material 40 is the first self-leveling. The material 40 is laid in a fluid state and is embedded in the middle portion of the edge surface 32 while moving in parallel with the board surfaces (bottom surface 31 and top surface 33) 31 and 33.
As a result, when the board-shaped heat insulating material 30 is laid, the board-shaped heat insulating material 30 is slightly moved in the front-back and left-right directions in parallel with the board surfaces 31 and 33, instead of simply laying them on the first self-leveling material 40. However, the air between the board-shaped heat insulating material 30 and the first self-leveling material 40 is evacuated by pressing it against the first self-leveling material 40 and submerging it from 1 mm to about 2/3 of the thickness of the board-shaped heat insulating material 30. , Eliminate the floating and make it adhere. Further, by wrapping the first self-leveling material 40 around the edge surface 32 portion of the board-shaped heat insulating material 30, not only the bottom surface 31 of the board-shaped heat insulating material 30 but also the edge surface 32 is firmly adhered and fixed as an adhesive surface. Therefore, the adhesive force and the fixing force of the board-shaped heat insulating material 30 against the impact force leading to peeling are improved.

本発明の対象となる床スラブ１０及び外壁部２０は、コンクリート造りの建築物に備わる外壁部２０と連続した床スラブ１０としては、鉄筋コンクリート造り（ＲＣ造）、鉄骨鉄筋コンクリート造り（ＳＲＣ造）、ガラスファイバー入りの鉄筋コンクリート造り（ＧＲＣ造）、プレキャストコンクリート造り（ＰＣ造、プレハブ））等のいずれであっても良い。
また、ここでの床スラブ１０は、外壁部２０に連続して上下を仕切る床版、途中階を仕切ると共に外壁部２０から水平に連続するコンクリート造りの床版を広く含むものである。 The floor slab 10 and the outer wall portion 20 which are the objects of the present invention are made of reinforced concrete (RC structure), steel-framed reinforced concrete structure (SRC structure), and glass as the floor slab 10 continuous with the outer wall portion 20 provided in the concrete building. It may be either a reinforced concrete structure containing fiber (GRC structure), a precast concrete structure (PC structure, prefab), or the like.
Further, the floor slab 10 here broadly includes a floor slab that continuously partitions the upper and lower parts of the outer wall portion 20, and a concrete floor slab that partitions the middle floor and is horizontally continuous from the outer wall portion 20.

本実施の形態に係る建築物の断熱構造１は、図１に示すように、コンクリート造りの床スラブ１０に立設されたコンクリート造りの外壁部２０に対し、先に床スラブ１０にボード状断熱材３０を設置することで断熱補強を行い、その後に外壁部２０に対して断熱施工を行う。
床スラブ１０の断熱補強を行う範囲は、例えば外壁部２０の端部から４００～６００ｍｍの範囲であり、この範囲を断熱することで、外壁部２０に対して床スラブ１０が熱橋とならないようにすることができる。
この建築物の断熱構造１は、床スラブ１０上に、第１のセルフレベリング材４０を流し込み、左官コテなどで平坦に均し、第１のセルフレベリング材４０上にボード状断熱材３０を敷き込む。 As shown in FIG. 1, the heat insulating structure 1 of the building according to the present embodiment has a board-shaped heat insulating structure on the floor slab 10 first with respect to the concrete outer wall portion 20 erected on the concrete floor slab 10. Insulation reinforcement is performed by installing the material 30, and then heat insulation construction is performed on the outer wall portion 20.
The range for insulating and reinforcing the floor slab 10 is, for example, a range of 400 to 600 mm from the end of the outer wall portion 20, and by insulating this range, the floor slab 10 does not become a thermal bridge with respect to the outer wall portion 20. Can be.
In the heat insulating structure 1 of this building, the first self-leveling material 40 is poured onto the floor slab 10, flattened with a plastering iron or the like, and the board-shaped heat insulating material 30 is laid on the first self-leveling material 40. Include.

このボード状断熱材３０を敷き込む際には、第１のセルフレベリング材４０上に単に並べるだけでなく、ボード状断熱材３０のボード面３１，３３と平行に移動させるとともに、小口面３２の中間部まで埋設されるように押し込む（図１（ｂ）参照）。
こうすることで、ボード状断熱材３０の底面３１に空気を巻き込むことがなく、浮き上がりなどを防止してボード状断熱材３０を底面３１及び小口面３２で第１のセルフレベリング材４０に密着させて固定する。 When laying the board-shaped heat insulating material 30, it is not only arranged on the first self-leveling material 40, but also moved in parallel with the board surfaces 31 and 33 of the board-shaped heat insulating material 30 and the edge surface 32. Push it so that it is buried up to the middle part (see FIG. 1 (b)).
By doing so, air is not entrained in the bottom surface 31 of the board-shaped heat insulating material 30, and the board-shaped heat insulating material 30 is brought into close contact with the first self-leveling material 40 on the bottom surface 31 and the edge surface 32 by preventing floating and the like. And fix it.

このような第１のセルフレベリング材４０は、外壁部２０との間に１０ｍｍ以上の隙間Ｄ１を形成するとともに、外壁部２０と反対側においても１０ｍｍ以上の隙間Ｄ２をあけて第１のセルフレベリング材４０を形成できるように、図示省略したが枠材を配置したり、予め床スラブ１０に切り欠き部を形成しておくようにする。また、第１のセルフレベリング材４０は、床スラブ１０の不陸の大きさに対して平坦にできる厚さに形成され、例えば厚さを５ｍｍ以上とする。
このような隙間Ｄ１，Ｄ２を外壁部２０に対する垂直方向（例えば前後方向：図１（ｂ）の紙面上の左右方向）に形成しておき、隙間Ｄ１，Ｄ２を形成した範囲に第１のセルフレベリング材４０を流し込むことでボード状断熱材３０をボード面と平行に移動することを可能とする（図４参照）。
なお、ボード状断熱材３０を連続させる隣接させるボード状断熱材３０との間の目地部には、第１のセルフレベリング材４０を介在させないように外壁部２０と平行な方向（例えば前後方向に対する左右方向：図１（ｂ）の紙面に垂直な方向）には、ボード状断熱材３０同士を密着させる。こうすることで、ボード状断熱材３０同士の目地部に第１のセルフレベリング材４０が介在して熱橋が生じることを防止する。
また、ボード状断熱材３０同士の目地部や床スラブ１０との境界部分には、ファイバーテープなどを貼って目地部の補強や境界部分での後述する第２のセルフレベリング材６０のクラックの発生などを防止する。 Such a first self-leveling material 40 forms a gap D1 of 10 mm or more with the outer wall portion 20, and also has a gap D2 of 10 mm or more on the opposite side of the outer wall portion 20 for the first self-leveling. Although not shown, a frame material is arranged so that the material 40 can be formed, or a notch portion is formed in advance on the floor slab 10. Further, the first self-leveling material 40 is formed to have a thickness that can be flattened with respect to the non-landing size of the floor slab 10, and the thickness is, for example, 5 mm or more.
Such gaps D1 and D2 are formed in the direction perpendicular to the outer wall portion 20 (for example, the front-back direction: the left-right direction on the paper surface of FIG. 1B), and the first self is formed in the range where the gaps D1 and D2 are formed. By pouring the leveling material 40, the board-shaped heat insulating material 30 can be moved in parallel with the board surface (see FIG. 4).
It should be noted that the joint portion between the board-shaped heat insulating material 30 and the adjacent board-shaped heat insulating material 30 is in a direction parallel to the outer wall portion 20 (for example, in the front-rear direction) so as not to interpose the first self-leveling material 40. Left-right direction: In the direction perpendicular to the paper surface of FIG. 1B), the board-shaped heat insulating materials 30 are brought into close contact with each other. By doing so, it is possible to prevent the first self-leveling material 40 from interposing the first self-leveling material 40 at the joints between the board-shaped heat insulating materials 30 to form a thermal bridge.
Further, a fiber tape or the like is attached to the joint portion between the board-shaped heat insulating materials 30 and the boundary portion with the floor slab 10 to reinforce the joint portion and cracks of the second self-leveling material 60 described later occur at the boundary portion. And so on.

ボード状断熱材３０は、従来から断熱ボードとして用いられているものを用いることができ、例えば硬質ウレタンフォームによる板状体の表裏両面に防湿層付の補強層を備えてボード状に成形した構造のものが用いられ、厚さが１０，１５，２０，２５，３０ｍｍ、幅が４５０，６００ｍｍ、長さが１８００，２７００ｍｍとした大きさに規格されたものが用いられる。なお、ボード状断熱材３０は、これらの規格されたものに限らず、必要な断熱性能や施工に適した大きさのものを適宜作成して用いるようにすれば良い。 As the board-shaped heat insulating material 30, one that has been conventionally used as a heat insulating board can be used. The one with a thickness of 10, 15, 20, 25, 30 mm, a width of 450, 600 mm, and a length of 1800, 2700 mm is used. The board-shaped heat insulating material 30 is not limited to these standardized materials, and may be appropriately prepared and used with a required heat insulating performance and a size suitable for construction.

第１のセルフレベリング材４０は、例えばセメント系の速硬・速乾タイプのものが用いられ、セルフレベリング材として市販されているものを用いることができる。また、第１のセルフレベリング材４０の施工前に、床スラブ１０上には、必要なプライマーを塗布する。プライマーは、第１のセルフレベリング材４０に対し、メーカー指定ものを用いることが好ましい。 As the first self-leveling material 40, for example, a cement-based quick-hardening / quick-drying type is used, and a commercially available self-leveling material can be used. Further, before the construction of the first self-leveling material 40, a necessary primer is applied on the floor slab 10. It is preferable to use a primer specified by the manufacturer for the first self-leveling material 40.

こうしてボード状断熱材３０を床スラブ１０上に第１のセルフレベリング材４０を介して埋設状態で密着させた後、図１（ａ）に示すように、外壁部２０に対し外壁部断熱材５０の断熱施工が行われる。
外壁部断熱材５０は、例えば現場発泡により発泡ウレタンを吹き付けることで、断熱施工を行う。
外壁部断熱材５０は、床スラブ１０の上面に第１のセルフレベリング材４０を介してボード状断熱材３０が取り付けてあり、外壁部２０との間には、隙間Ｄ１が形成されてその部分に第１のセルフレベリング材４０が介在していることから、隙間Ｄ１の第１のセルフレベリング材４０を覆いかつボード状断熱材３０の端縁部と外壁部断熱材５０とが接触して断熱材同士３０，５０に隙間が生じないように吹き付けが行われる。
また、外壁部断熱材５０は、ボード状断熱材３０と同一仕様のボード状のものでも良く、例えば硬質ポリウレタンフォーム、ポリスチレンフォーム、ポリエチレンフォーム、フェノールフォーム、ゴム発泡体、塩化ビニル発泡体のボード、あるいは板状のグラスウールやロックウールなどが使用でき、またこれらに紙、ポリエチレンフィルム、ガラス不織布、石膏ボード、合板など単層、あるいはこれらを１種類以上積層した面材が予め設けてあるものが、床面の強度を向上できるので好ましい。
外壁部断熱材５０の施工に際し、床スラブ１０上のボード状断熱材３０上で作業者が作業したり、資材の運搬などが行われ踏まれることがあるが、ボード状断熱材３０が第１のセルフレベリング材４０上に密着状態で固定されているので、ボード状断熱材３０に浮きやセルフレベリング材からの剥がれが生じることがなく、支障なく作業や運搬などを行うことができる。 In this way, the board-shaped heat insulating material 30 is adhered to the floor slab 10 in a state of being embedded via the first self-leveling material 40, and then, as shown in FIG. 1A, the outer wall heat insulating material 50 is attached to the outer wall 20. Insulation work is done.
The outer wall heat insulating material 50 is heat-insulated by, for example, spraying urethane foam by in-situ foaming.
The outer wall heat insulating material 50 has a board-shaped heat insulating material 30 attached to the upper surface of the floor slab 10 via a first self-leveling material 40, and a gap D1 is formed between the outer wall heat insulating material 50 and the outer wall heat insulating material 50. Since the first self-leveling material 40 is interposed in the space D1, the first self-leveling material 40 in the gap D1 is covered and the edge portion of the board-shaped heat insulating material 30 and the outer wall heat insulating material 50 are in contact with each other to insulate. Spraying is performed so that there is no gap between the materials 30 and 50.
Further, the outer wall heat insulating material 50 may be a board-shaped material having the same specifications as the board-shaped heat insulating material 30, and may be, for example, a rigid polyurethane foam, a polystyrene foam, a polyethylene foam, a phenol foam, a rubber foam, or a vinyl chloride foam board. Alternatively, plate-shaped glass wool or rock wool can be used, and a single layer such as paper, polyethylene film, glass non-woven fabric, gypsum board, plywood, or a face material obtained by laminating one or more of these is provided in advance. It is preferable because it can improve the strength of the floor surface.
When constructing the outer wall heat insulating material 50, a worker may work on the board-shaped heat insulating material 30 on the floor slab 10, or materials may be transported and stepped on, but the board-shaped heat insulating material 30 is the first. Since the board-shaped heat insulating material 30 is fixed in close contact with the self-leveling material 40, the board-shaped heat insulating material 30 does not float or peel off from the self-leveling material, and work and transportation can be performed without any trouble.

外壁部断熱材５０を施工後は、ボード状断熱材３０の上面に、必要に応じてプライマーが塗布された後、第２のセルフレベリング材６０を流し込み、外壁部断熱材５０に接触し、ボード状断熱材３０を覆うようにして平坦に均す。
この第２のセルフレベリング材６０は、第１のセルフレベリング材４０と同一仕様のものが用いられるほか、異なる仕様のものであっても良く、床仕上げ材７０の下地材とすることができるものであれば良い。
第２のセルフレベリング材６０は、例えば厚さを１０ｍｍ以上とし、左官コテ等を使用して平滑に均す。この第２のセルフレベリング材６０は、床仕上げ材７０の下地材となる。 After the outer wall heat insulating material 50 is installed, a primer is applied to the upper surface of the board-shaped heat insulating material 30 as necessary, and then a second self-leveling material 60 is poured into the board to contact the outer wall heat insulating material 50. Flatly level the heat insulating material 30 so as to cover it.
The second self-leveling material 60 may have the same specifications as the first self-leveling material 40, or may have different specifications, and may be used as a base material for the floor finishing material 70. If it is good.
The second self-leveling material 60 has a thickness of, for example, 10 mm or more, and is smoothed using a plastering iron or the like. The second self-leveling material 60 serves as a base material for the floor finishing material 70.

この後、第２のセルフレベリング材６０の上には、床仕上げ材７０が取り付けられて床面の施工が行われ、外壁部断熱材５０の内側には、内装材８０及び幅木９０が取り付けられて内壁面の内装が行われる。これら床仕上げ材７０の施工や内壁面の内装材８０などの施工は、これまでの方法や構造と同様にして行われ、使用される床仕上げ材７０や内装材８０もこれまで使用されているものを広く使用することができる。 After that, the floor finishing material 70 is attached on the second self-leveling material 60 to construct the floor surface, and the interior material 80 and the skirting board 90 are attached to the inside of the outer wall heat insulating material 50. The interior of the inner wall is done. The construction of the floor finishing material 70 and the construction of the interior material 80 of the inner wall surface are carried out in the same manner as the conventional methods and structures, and the floor finishing material 70 and the interior material 80 used so far have also been used.

このような建築物の断熱構造１によれば、ボード状断熱材３０の敷き込み時に、単に第１のセルフレベリング材４０の上に敷き並べるのではなく、ボード状断熱材３０を少し前後左右方向にボード面３１，３３と平行に動かしながら、第１のセルフレベリング材４０に押し付け１ｍｍからボード状断熱材３０厚さの２／３程度まで沈めるようにして、ボード状断熱材３０と第１のセルフレベリング材４０の間の空気を抜き、浮き上がりをなくして密着させることができる。
これにより、ボード状断熱材３０の小口面３２部分に第１のセルフレベリング材４０が廻り込むことで、ボード状断熱材３０の底面３１だけでなく、小口面３２も接着面として確実に接着固定することができ、剥がれにつながる衝撃力に対するボード状断熱材３０の密着力や固定力を確保することができる。
また、第１のセルフレベリング材４０と外壁部２０との間に隙間Ｄ１を形成してもボード状断熱材３０と外壁部断熱材５０とを接触させて設置しているので、熱橋とならずに断熱性を確保することができる。
また、床スラブ１０にボード状断熱材３０を先に施工することで、ボード状断熱材３０が踏まれたり、資材の積載などで外力が加わることがあっても密着状態で取り付けられているので、ボード状断熱材３０に浮きやセルフレベリング材からの剥がれなどが発生することを防止でき、床仕上げ材７０の下地とすることができる。 According to the heat insulating structure 1 of such a building, when the board-shaped heat insulating material 30 is laid, the board-shaped heat insulating material 30 is not simply laid on the first self-leveling material 40, but the board-shaped heat insulating material 30 is slightly arranged in the front-back and left-right directions. While moving in parallel with the board surfaces 31 and 33, the board-shaped heat insulating material 30 and the first self-inflating material 30 are pressed against the first self-leveling material 40 so as to be submerged from 1 mm to about 2/3 of the thickness of the board-shaped heat insulating material 30. The air between the self-leveling materials 40 can be evacuated to eliminate floating and bring them into close contact with each other.
As a result, the first self-leveling material 40 wraps around the edge surface 32 portion of the board-shaped heat insulating material 30, so that not only the bottom surface 31 of the board-shaped heat insulating material 30 but also the edge surface 32 is securely adhered and fixed as an adhesive surface. It is possible to secure the adhesive force and the fixing force of the board-shaped heat insulating material 30 against the impact force leading to peeling.
Further, even if a gap D1 is formed between the first self-leveling material 40 and the outer wall portion 20, the board-shaped heat insulating material 30 and the outer wall portion heat insulating material 50 are installed in contact with each other, so that it is a thermal bridge. Insulation can be ensured without the need for heat insulation.
Further, by installing the board-shaped heat insulating material 30 on the floor slab 10 first, even if the board-shaped heat insulating material 30 is stepped on or an external force is applied due to the loading of materials, the board-shaped heat insulating material 30 is attached in a close contact state. , It is possible to prevent the board-shaped heat insulating material 30 from floating or peeling from the self-leveling material, and it can be used as a base for the floor finishing material 70.

次に、本発明の建築物の断熱構造１の他の実施の形態について、図２により説明する。なお、上記実施の形態と同一部分には、同一符号を記し、重複する説明は省略する。
本実施の形態の建築物の断熱構造１では、床スラブ１０に第１のセルフレベリング材４０を介してボード状断熱材３０を施工し、ボード状断熱材３０の上に第２のセルフレベリング材６０を施工した後、外壁部断熱材５０を施工する場合であり、第２のセルフレベリング材６０の施工順序が外壁部断熱材５０の施工後から施工前に変更したものである。 Next, another embodiment of the heat insulating structure 1 of the building of the present invention will be described with reference to FIG. The same parts as those in the above embodiment are designated by the same reference numerals, and duplicate description will be omitted.
In the heat insulating structure 1 of the building of the present embodiment, the board-shaped heat insulating material 30 is constructed on the floor slab 10 via the first self-leveling material 40, and the second self-leveling material is placed on the board-shaped heat insulating material 30. This is a case where the outer wall heat insulating material 50 is constructed after the construction of 60, and the construction order of the second self-leveling material 60 is changed from after the construction of the outer wall heat insulating material 50 to before the construction.

この建築物の断熱構造１では、ボード状断熱材３０の床スラブ１０への施工及び断熱構造は、既に説明したものと同一である。
こうしてボード状断熱材３０を床スラブ１０上に第１のセルフレベリング材４０を介して埋設状態で密着させた後、図２（ａ）に示すように、ボード状断熱材３０上に第２のセルフレベリング材６０の施工を行い床仕上げ材７０の下地とする。
第２のセルフレベリング材６０を施工するため、ボード状断熱材３０上に第２のセルフレベリング材６０を流し込むと、ボード状断熱材３０の外壁部２０側の端面を第２のセルフレベリング材６０が覆うこととなり、後に施工する外壁部断熱材５０とボード状断熱材３０と連続させることができなくなる。
そこで、ボード状断熱材３０の外壁部２０側の端縁部にボード状断熱材３０を細くした堰用断熱材３５を配置する。この堰用断熱材３５は、ボード状断熱材３０の一部となるものであり、ボード状断熱材３０と同一仕様で、規格されたボード状断熱材３０の幅を狭くカットしたものが用いられ、接着剤や両面テープなどで固定する。堰用断熱材３５は、幅は、第２のセルフレベリング材６０をせき止めることができる強度を確保できれば良く、少なくとも１０ｍｍ以上とされる。また、堰用断熱材３５の高さは、第２のセルフレベリング材６０の施工厚さに応じて設定するが、第２のセルフレベリング材６０を１０ｍｍ以上とすることに対応して１０ｍｍ以上とされ、規格品を用いる場合には、１０，１５，２０ｍｍのいずれかを使用すれば良い。
こうして堰用断熱材３５をボード状断熱材３０の外壁部２０側の端縁部に取り付けた後、第２のセルフレベリング材６０を流し込み、左官コテ等で平坦に均してボード状断熱材３０上に第２のセルフレベリング材６０による床仕上げ材７０の下地を形成する。この状態では、ボード状断熱材３０の外壁部２０側には、隙間Ｄ１が形成され、ボード状断熱材３０の中間部より上側の端面と堰用断熱材３５の端面とが露出した状態となっている。 In the heat insulating structure 1 of this building, the construction of the board-shaped heat insulating material 30 on the floor slab 10 and the heat insulating structure are the same as those already described.
In this way, the board-shaped heat insulating material 30 is adhered to the floor slab 10 in a buried state via the first self-leveling material 40, and then, as shown in FIG. 2A, the second board-shaped heat insulating material 30 is placed on the board-shaped heat insulating material 30. The self-leveling material 60 is constructed and used as a base for the floor finishing material 70.
When the second self-leveling material 60 is poured onto the board-shaped heat insulating material 30 in order to construct the second self-leveling material 60, the end surface of the board-shaped heat insulating material 30 on the outer wall portion 20 side is turned into the second self-leveling material 60. Will be covered, and it will not be possible to connect the outer wall heat insulating material 50 and the board-shaped heat insulating material 30 to be constructed later.
Therefore, a weir heat insulating material 35 in which the board-shaped heat insulating material 30 is thinned is arranged at the edge portion on the outer wall portion 20 side of the board-shaped heat insulating material 30. The weir heat insulating material 35 is a part of the board-shaped heat insulating material 30, and the standard board-shaped heat insulating material 30 having the same specifications as the board-shaped heat insulating material 30 is used. , Fix with adhesive or double-sided tape. The width of the weir heat insulating material 35 is set to be at least 10 mm or more as long as the strength capable of damming the second self-leveling material 60 can be secured. Further, the height of the heat insulating material 35 for the weir is set according to the construction thickness of the second self-leveling material 60, but is 10 mm or more corresponding to the case where the second self-leveling material 60 is 10 mm or more. When a standard product is used, any of 10, 15, and 20 mm may be used.
In this way, after the weir heat insulating material 35 is attached to the edge portion of the board-shaped heat insulating material 30 on the outer wall portion 20 side, the second self-leveling material 60 is poured and leveled flat with a plastering iron or the like, and the board-shaped heat insulating material 30 is used. The base of the floor finishing material 70 is formed on the second self-leveling material 60. In this state, a gap D1 is formed on the outer wall portion 20 side of the board-shaped heat insulating material 30, and the end surface above the intermediate portion of the board-shaped heat insulating material 30 and the end surface of the weir heat insulating material 35 are exposed. ing.

こうして床スラブ１０上にボード状断熱材３０が第１のセルフレベリング材４０を介して固定され、さらにボード状断熱材３０の上に堰用断熱材３５でせき止められて第２のセルフレベリング材６０による床仕上げ材７０の下地を形成した後、外壁部２０に対し外壁部断熱材５０の断熱施工が行われる。
外壁部断熱材５０は、例えば現場発泡により発泡ウレタンを吹き付けることで、断熱施工が行われ、ボード状断熱材３０及び堰用断熱材３５と外壁部断熱材５０が連続するように施工される。この外壁部断熱材５０の構造及び施工は、既に説明した実施の形態と同一であり、重複する説明は、省略する。なお、この場合の外壁部断熱材５０についても現場発泡による断熱施工に限らず、ボード状断熱材を用いる構造及び施工方法であっても良い。 In this way, the board-shaped heat insulating material 30 is fixed on the floor slab 10 via the first self-leveling material 40, and further dammed on the board-shaped heat insulating material 30 by the weir heat insulating material 35 to form the second self-leveling material 60. After forming the base of the floor finishing material 70 by the above method, heat insulating construction of the outer wall portion heat insulating material 50 is performed on the outer wall portion 20.
The outer wall heat insulating material 50 is heat-insulated by spraying urethane foam, for example, by in-situ foaming, so that the board-shaped heat insulating material 30, the weir heat insulating material 35, and the outer wall heat insulating material 50 are continuously constructed. The structure and construction of the outer wall heat insulating material 50 are the same as those of the embodiments already described, and overlapping description will be omitted. The outer wall heat insulating material 50 in this case is not limited to the heat insulating construction by on-site foaming, and may be a structure and a construction method using a board-shaped heat insulating material.

このような建築物の断熱構造１によれば、ボード状断熱材３０の敷き込み時に、単に第１のセルフレベリング材４０の上に敷き並べるのではなく、ボード状断熱材３０を少し前後左右方向にボード面３１，３３と平行に動かしながら、第１のセルフレベリング材４０に押し付け１ｍｍからボード状断熱材３０厚さの２／３程度まで沈めるようにして、ボード状断熱材３０と第１のセルフレベリング材４０の間の空気を抜き、浮き上がりをなくして密着させることができる。
これにより、ボード状断熱材３０の小口面３２部分に第１のセルフレベリング材４０が廻り込むことで、ボード状断熱材３０の底面３１だけでなく、小口面３２も接着面として確実に接着固定することができ、剥がれにつながる衝撃力に対するボード状断熱材３０の密着力や固定力を確保することができる。
また、第１のセルフレベリング材４０及び堰用断熱材３５と外壁部２０との間に隙間Ｄ１を形成してもボード状断熱材３０及び堰用断熱材３５と外壁部断熱材５０とを接触させて設置しているので、熱橋とならずに断熱性を確保することができる。
また、床スラブ１０にボード状断熱材３０を先に施工し、ボード状断熱材３０上に第２のセルフレベリング材６０を施工することで、ボード状断熱材３０が直接踏まれたり、資材の積載などで外力が加わることがなく、第２のセルフレベリング材６０によってボード状断熱材３０を踏まれたり、直接外力が加わることを回避でき、ボード状断熱材３０に浮きやセルフレベリング材からの剥がれなどが発生することを防止でき、床仕上げ材７０の下地とすることができる。 According to the heat insulating structure 1 of such a building, when the board-shaped heat insulating material 30 is laid, the board-shaped heat insulating material 30 is not simply laid on the first self-leveling material 40, but the board-shaped heat insulating material 30 is slightly arranged in the front-back and left-right directions. While moving in parallel with the board surfaces 31 and 33, the board-shaped heat insulating material 30 and the first self-inflating material 30 are pressed against the first self-leveling material 40 so as to be submerged from 1 mm to about 2/3 of the thickness of the board-shaped heat insulating material 30. The air between the self-leveling materials 40 can be evacuated to eliminate floating and bring them into close contact with each other.
As a result, the first self-leveling material 40 wraps around the edge surface 32 portion of the board-shaped heat insulating material 30, so that not only the bottom surface 31 of the board-shaped heat insulating material 30 but also the edge surface 32 is securely adhered and fixed as an adhesive surface. It is possible to secure the adhesive force and the fixing force of the board-shaped heat insulating material 30 against the impact force leading to peeling.
Further, even if a gap D1 is formed between the first self-leveling material 40 and the weir heat insulating material 35 and the outer wall portion 20, the board-shaped heat insulating material 30 and the weir heat insulating material 35 and the outer wall portion heat insulating material 50 are in contact with each other. Since it is installed so that it does not become a thermal bridge, it is possible to secure heat insulation.
Further, by installing the board-shaped heat insulating material 30 on the floor slab 10 first and then installing the second self-leveling material 60 on the board-shaped heat insulating material 30, the board-shaped heat insulating material 30 can be directly stepped on or the material can be used. No external force is applied due to loading or the like, and the board-shaped heat insulating material 30 can be prevented from being stepped on by the second self-leveling material 60 or directly applied to the board-shaped heat insulating material 30. It is possible to prevent peeling and the like, and it can be used as a base for the floor finishing material 70.

次に、本発明の建築物の断熱構造１の他の実施の形態について、図３により説明する。なお、上記実施の形態と同一部分には、同一符号を記し、重複する説明は省略する。
本実施の形態の建築物の断熱構造１では、これまでの実施の形態と異なり、まず外壁部２０に外壁部断熱材５０の施工を行った後、床スラブ１０の断熱施工を行う場合である。 Next, another embodiment of the heat insulating structure 1 of the building of the present invention will be described with reference to FIG. The same parts as those in the above embodiment are designated by the same reference numerals, and duplicate description will be omitted.
In the heat insulating structure 1 of the building of the present embodiment, unlike the previous embodiments, the outer wall portion 20 is first constructed with the outer wall portion heat insulating material 50, and then the floor slab 10 is heat-insulated. ..

まず、外壁部断熱材５０を施工する。外壁部断熱材５０は、既に説明したように、現場発泡による発泡ウレタンを吹き付けることで行われたり、ボード状断熱材３０を取り付けることで行われる。外壁部断熱材５０は、床スラブ１０上に下端部を接触させ、外壁部２０の壁面の内側に沿って施工する。 First, the outer wall heat insulating material 50 is constructed. As described above, the outer wall heat insulating material 50 is formed by spraying urethane foam produced by in-situ foaming, or by attaching a board-shaped heat insulating material 30. The outer wall heat insulating material 50 is constructed along the inside of the wall surface of the outer wall portion 20 with the lower end portion in contact with the floor slab 10.

外壁部２０への外壁部断熱材５０の施工が完了した後、床スラブ１０に対する断熱施工が行われる。
床スラブ１０への断熱施工では、外壁部２０に外壁部断熱材５０が施工されているので、外壁部断熱材５０にボード状断熱材３０を接触させるようにする。
すなわち、床スラブ１０上の第１のセルフレベリング材４０は、ボード状断熱材３０と外壁部２０との間には、介在されずに設けられ（外壁部２０とボード状断熱材３０の間には第１のセルフレベリング材４０が介在された隙間Ｄ１は形成されず）、その第１のセルフレベリング材４０上に配置されたボード状断熱材３０は、外壁部２０に沿って隣接させるボード状断熱材３０との間の目地部、並びに外壁部断熱材５０と接触するボード状断熱材３０の部位を除く端面の中間部まで埋設するようにして第１のセルフレベリング材４０に固定する。
こうすることで、床スラブ１０に第１のセルフレベリング材４０を介してボード状断熱材３０を外壁部断熱材５０に連続させて施工することができ、ボード状断熱材３０の小口面３２部分に第１のセルフレベリング材４０が廻り込むことで、ボード状断熱材３０の底面３１だけでなく、小口面３２も接着面として確実に接着固定することができ、剥がれにつながる衝撃力に対するボード状断熱材３０の密着力や固定力を確保することができる。 After the construction of the outer wall heat insulating material 50 on the outer wall 20 is completed, the heat insulating construction is performed on the floor slab 10.
In the heat insulating construction on the floor slab 10, since the outer wall portion heat insulating material 50 is constructed on the outer wall portion 20, the board-shaped heat insulating material 30 is brought into contact with the outer wall portion heat insulating material 50.
That is, the first self-leveling material 40 on the floor slab 10 is provided without being interposed between the board-shaped heat insulating material 30 and the outer wall portion 20 (between the outer wall portion 20 and the board-shaped heat insulating material 30). The gap D1 in which the first self-leveling material 40 is interposed is not formed), and the board-shaped heat insulating material 30 arranged on the first self-leveling material 40 has a board shape adjacent to the outer wall portion 20. It is fixed to the first self-leveling material 40 by burying up to the joint portion between the heat insulating material 30 and the middle portion of the end surface excluding the portion of the board-shaped heat insulating material 30 that comes into contact with the outer wall heat insulating material 50.
By doing so, the board-shaped heat insulating material 30 can be continuously applied to the outer wall heat insulating material 50 via the first self-leveling material 40 on the floor slab 10, and the edge surface 32 portion of the board-shaped heat insulating material 30 can be continuously applied. By wrapping around the first self-leveling material 40, not only the bottom surface 31 of the board-shaped heat insulating material 30 but also the edge surface 32 can be securely adhered and fixed as an adhesive surface, and the board shape against the impact force leading to peeling. It is possible to secure the adhesive force and the fixing force of the heat insulating material 30.

こうしてボード状断熱材３０を第１のセルフレベリング材４０を介して床スラブ１０に固定した後、ボード状断熱材３０の上に第２のセルフレベリング材６０を施工するが、第２のセルフレベリング材６０の構造や施工は、既に説明したものと同一である。
さらに、第２のセルフレベリング材６０の施工後、第２のセルフレベリング材６０の上には、床仕上げ材７０が取り付けられて床面の施工が行われ、外壁部断熱材５０の内側には、内装材８０及び幅木９０が取り付けられて内壁面の内装が行われる。これら床仕上げ材７０の施工や内壁面の内装材８０などの施工は、これまでの方法や構造と同様にして行われ、使用される床仕上げ材７０や内装材８０もこれまで使用されているものを広く使用することができる。 In this way, after the board-shaped heat insulating material 30 is fixed to the floor slab 10 via the first self-leveling material 40, the second self-leveling material 60 is constructed on the board-shaped heat insulating material 30, but the second self-leveling is performed. The structure and construction of the material 60 are the same as those already described.
Further, after the construction of the second self-leveling material 60, the floor finishing material 70 is attached on the second self-leveling material 60 to construct the floor surface, and the inside of the outer wall heat insulating material 50 is covered. , Interior material 80 and skirting board 90 are attached to interior the inner wall surface. The construction of the floor finishing material 70 and the construction of the interior material 80 of the inner wall surface are carried out in the same manner as the conventional methods and structures, and the floor finishing material 70 and the interior material 80 used so far have also been used. Can be widely used.

このような建築物の断熱構造１によれば、ボード状断熱材３０の敷き込み時に、単に第１のセルフレベリング材４０の上に敷き並べるのではなく、ボード状断熱材３０を少し前後左右方向にボード面３１，３３と平行に動かしながら、第１のセルフレベリング材４０に押し付け１ｍｍからボード状断熱材３０厚さの２／３程度まで沈めるようにして、ボード状断熱材３０と第１のセルフレベリング材４０の間の空気を抜き、浮き上がりをなくして密着させることができる。
これにより、ボード状断熱材３０の外壁部２０側や目地部を除く小口面３２部分に第１のセルフレベリング材４０が廻り込むことで、ボード状断熱材３０の底面３１だけでなく、小口面３２も接着面として確実に接着固定することができ、剥がれにつながる衝撃力に対するボード状断熱材３０の密着力や固定力を確保することができる。
また、第１のセルフレベリング材４０と外壁部２０の外壁部断熱材５０との間に隙間がなくボード状断熱材３０と外壁部断熱材５０とが接触して設置されているので、熱橋とならずに断熱性を確保することができる。
また、外壁部２０の内壁面に外壁部断熱材５０を先に施工し、その後にボード状断熱材３０を床スラブ１０上に第１のセルフレベリング材４０を介して施工することで、ボード状断熱材３０が外壁部断熱材５０の施工の際に直接踏まれたり、資材の積載などで外力が加わることがなく、ボード状断熱材３０に浮きやセルフレベリング材からの剥がれなどが発生することを防止でき、床仕上げ材７０の下地とすることができる。 According to the heat insulating structure 1 of such a building, when the board-shaped heat insulating material 30 is laid, the board-shaped heat insulating material 30 is not simply laid on the first self-leveling material 40, but the board-shaped heat insulating material 30 is slightly arranged in the front-back and left-right directions. While moving in parallel with the board surfaces 31 and 33, the board-shaped heat insulating material 30 and the first self-inflating material 30 are pressed against the first self-leveling material 40 so as to be submerged from 1 mm to about 2/3 of the thickness of the board-shaped heat insulating material 30. The air between the self-leveling materials 40 can be evacuated to eliminate floating and bring them into close contact with each other.
As a result, the first self-leveling material 40 wraps around the edge surface 32 portion excluding the outer wall portion 20 side and the joint portion of the board-shaped heat insulating material 30, so that not only the bottom surface 31 of the board-shaped heat insulating material 30 but also the edge surface is formed. 32 can also be securely adhered and fixed as an adhesive surface, and the adhesion and fixing force of the board-shaped heat insulating material 30 against the impact force leading to peeling can be secured.
Further, since there is no gap between the first self-leveling material 40 and the outer wall heat insulating material 50 of the outer wall 20, the board-shaped heat insulating material 30 and the outer wall heat insulating material 50 are installed in contact with each other, so that the thermal bridge is installed. Insulation can be ensured without becoming.
Further, the outer wall heat insulating material 50 is first applied to the inner wall surface of the outer wall 20, and then the board-shaped heat insulating material 30 is applied to the floor slab 10 via the first self-leveling material 40 to form a board. The heat insulating material 30 is not directly stepped on during the construction of the outer wall heat insulating material 50, and no external force is applied due to the loading of materials, so that the board-shaped heat insulating material 30 floats or peels off from the self-leveling material. Can be prevented and can be used as a base for the floor finishing material 70.

以上の各実施の形態の建築物の断熱構造１とともに、具体的に説明したように、建築物の断熱構造１の施工方法によれば、図４に示すように、建築物の断熱構造１を施工するに際し、第１のセルフレベリング材４０に埋設固定されるボード状断熱材３０は、第１のセルフレベリング材４０が流動性のある状態で敷き込んでボード面３１，３３に平行に移動させながら小口面３２の中間部まで埋設するようにしている。
これにより、ボード状断熱材３０の敷き込み時に、単に第１のセルフレベリング材４０の上に敷き並べるのではなく、ボード状断熱材３０を少し前後左右方向にボード面３１，３３と平行に動かしながら、第１のセルフレベリング材４０に押し付け１ｍｍからボード状断熱材３０厚さの２／３程度まで沈めるようにして、ボード状断熱材３０と第１のセルフレベリング材４０の間の空気を抜き、浮き上がりをなくして密着させることができる。また、ボード状断熱材３０の小口面３２部分に第１のセルフレベリング材４０が廻り込むことでボード状断熱材３０の底面３１だけでなく、小口面３２も接着面として確実に接着固定することで、剥がれにつながる衝撃力に対するボード状断熱材３０の密着力や固定力を確保することができる。 According to the construction method of the heat insulating structure 1 of the building as specifically described together with the heat insulating structure 1 of the building of each of the above embodiments, as shown in FIG. 4, the heat insulating structure 1 of the building is provided. At the time of construction, the board-shaped heat insulating material 30 embedded and fixed in the first self-leveling material 40 is laid with the first self-leveling material 40 in a fluid state and moved in parallel with the board surfaces 31 and 33. However, it is buried up to the middle part of the edge surface 32.
As a result, when the board-shaped heat insulating material 30 is laid, the board-shaped heat insulating material 30 is slightly moved in the front-back and left-right directions in parallel with the board surfaces 31 and 33, instead of simply laying them on the first self-leveling material 40. However, the air between the board-shaped heat insulating material 30 and the first self-leveling material 40 is evacuated by pressing it against the first self-leveling material 40 and submerging it from 1 mm to about 2/3 of the thickness of the board-shaped heat insulating material 30. , It is possible to eliminate the floating and make it adhere. Further, by wrapping the first self-leveling material 40 around the edge surface 32 portion of the board-shaped heat insulating material 30, not only the bottom surface 31 of the board-shaped heat insulating material 30 but also the edge surface 32 is securely adhered and fixed as an adhesive surface. Therefore, it is possible to secure the adhesive force and the fixing force of the board-shaped heat insulating material 30 against the impact force leading to the peeling.

以上、実施の形態とともに、具体的に説明したように、本発明の建築物の断熱構造１によれば、コンクリート造りの床スラブ１０と、床スラブ１０に立設されるコンクリート造りの外壁部２０と、床スラブ１０上に設けられるボード状断熱材３０と、床スラブ１０上に設けられボード状断熱材３０の底面３１及び隣接するボード状断熱材３０との間の目地部を除く小口面３２の中間部まで埋設させて固定する第１のセルフレベリング材４０と、ボード状断熱材３０及び第１のセルフレベリング材４０上に設けられ外壁部２０を断熱する外壁部断熱材５０と、第１のセルフレベリング材４０に埋設されて固定されたボード状断熱材３０の上面３３を覆って設けられる第２のセルフレベリング材６０と、を備えて構成されている。
かかる構成によれば、ボード状断熱材３０の敷き込み時に、単に第１のセルフレベリング材４０の上に敷き並べるのではなく、ボード状断熱材３０を少し前後左右方向にボード面３１，３３と平行に動かしながら、第１のセルフレベリング材４０に押し付けボード状断熱材３０厚さの中間部まで沈めるようにすることで、ボード状断熱材３０と第１のセルフレベリング材４０の間の空気を抜き、浮き上がりをなくして密着させることができる。
これにより、ボード状断熱材３０の小口面３２部分に第１のセルフレベリング材４０が廻り込むことで、ボード状断熱材３０の底面３１だけでなく、小口面３２も接着面として確実に接着固定することができ、剥がれにつながる衝撃力に対するボード状断熱材３０の密着力や固定力を確保することができる。
また、第１のセルフレベリング材４０と外壁部２０との間に隙間Ｄ１を形成してもボード状断熱材３０と外壁部断熱材５０とを接触させて設置しているので、熱橋とならずに断熱性を確保することができる。
また、床スラブ１０にボード状断熱材３０を先に施工することで、ボード状断熱材３０が踏まれたり、資材の積載などで外力が加わることがあっても密着状態で取り付けられているので、ボード状断熱材３０に浮きやセルフレベリング材からの剥がれなどが発生することを防止でき、床仕上げ材７０の下地とすることができる。 As described above, together with the embodiment, as specifically described, according to the heat insulating structure 1 of the building of the present invention, the concrete floor slab 10 and the concrete outer wall portion 20 erected on the floor slab 10 And the edge surface 32 excluding the joint portion between the board-shaped heat insulating material 30 provided on the floor slab 10 and the bottom surface 31 of the board-shaped heat insulating material 30 provided on the floor slab 10 and the adjacent board-shaped heat insulating material 30. A first self-leveling material 40 that is buried and fixed up to the middle portion of the above, an outer wall heat insulating material 50 that is provided on the board-shaped heat insulating material 30 and the first self-leveling material 40 and that insulates the outer wall portion 20, and a first. A second self-leveling material 60 provided so as to cover the upper surface 33 of the board-shaped heat insulating material 30 embedded and fixed in the self-leveling material 40 is provided.
According to this configuration, when the board-shaped heat insulating material 30 is laid, the board-shaped heat insulating material 30 is not simply laid on the first self-leveling material 40, but the board-shaped heat insulating material 30 is slightly arranged with the board surfaces 31 and 33 in the front-back and left-right directions. While moving in parallel, the air between the board-shaped heat insulating material 30 and the first self-leveling material 40 is sunk by pressing it against the first self-leveling material 40 and submerging it to the middle portion of the thickness of the board-shaped heat insulating material 30. It can be pulled out and stuck without lifting.
As a result, the first self-leveling material 40 wraps around the edge surface 32 portion of the board-shaped heat insulating material 30, so that not only the bottom surface 31 of the board-shaped heat insulating material 30 but also the edge surface 32 is securely adhered and fixed as an adhesive surface. It is possible to secure the adhesive force and the fixing force of the board-shaped heat insulating material 30 against the impact force leading to peeling.
Further, even if a gap D1 is formed between the first self-leveling material 40 and the outer wall portion 20, the board-shaped heat insulating material 30 and the outer wall portion heat insulating material 50 are installed in contact with each other, so that it is a thermal bridge. Insulation can be ensured without the need for heat insulation.
Further, by installing the board-shaped heat insulating material 30 on the floor slab 10 first, even if the board-shaped heat insulating material 30 is stepped on or an external force is applied due to the loading of materials, the board-shaped heat insulating material 30 is attached in a close contact state. , It is possible to prevent the board-shaped heat insulating material 30 from floating or peeling from the self-leveling material, and it can be used as a base for the floor finishing material 70.

本発明の建築物の断熱構造１によれば、第２のセルフレベリング材６０は、外壁部２０側に設けた堰用断熱材３５で仕切られたボード状断熱材３０上に設けられることで、ボード状断熱材３０の上面に第２のセルフレベリング材６０を施工しても、外壁部断熱材５０との間に熱橋が形成されることを防止して外壁部断熱材５０とボード状断熱材３０及び堰用断熱材３５と連続させることができる。
これにより、外壁部断熱材５０の施工順序やボード状断熱材３０の施工順序を任意に選択して施工することが可能となる。 According to the heat insulating structure 1 of the building of the present invention, the second self-leveling material 60 is provided on the board-shaped heat insulating material 30 partitioned by the dam heat insulating material 35 provided on the outer wall portion 20 side. Even if the second self-leveling material 60 is installed on the upper surface of the board-shaped heat insulating material 30, it is possible to prevent a thermal bridge from being formed between the outer wall-shaped heat insulating material 50 and the outer wall-shaped heat insulating material 50 and the board-shaped heat insulating material 50. It can be made continuous with the material 30 and the heat insulating material 35 for a dam.
This makes it possible to arbitrarily select and construct the construction order of the outer wall heat insulating material 50 and the construction order of the board-shaped heat insulating material 30.

本発明の建築物の断熱構造１によれば、第１のセルフレベリング材４０は、ボード状断熱材３０と外壁部２０との間には、介在させずに設けられ、外壁部断熱材５０は、床スラブ１０上に設けられているので、外壁部２０に先に外壁部断熱材５０を施工した場合でもボード状断熱材３０と連続して設置することができ、熱橋が形成されることを防止することができる。また、ボード状断熱材３０は、第１のセルフレベリング材４０上に密着して固定することができ、衝撃力に対するボード状断熱材３０の密着力や固定力を確保することができる。 According to the heat insulating structure 1 of the building of the present invention, the first self-leveling material 40 is provided between the board-shaped heat insulating material 30 and the outer wall portion 20 without intervening, and the outer wall portion heat insulating material 50 is provided. Since it is provided on the floor slab 10, even if the outer wall heat insulating material 50 is installed on the outer wall 20 first, it can be continuously installed with the board-shaped heat insulating material 30 to form a thermal bridge. Can be prevented. Further, the board-shaped heat insulating material 30 can be adhered and fixed on the first self-leveling material 40, and the adhesive force and fixing force of the board-shaped heat insulating material 30 with respect to the impact force can be secured.

本発明の建築物の断熱構造１によれば、外壁部断熱材５０は、ボード状断熱材３０または、現場発泡断熱材であっても良く、いずれでも外壁部２０の断熱性を確保することができ、施工の自由度も増大する。 According to the heat insulating structure 1 of the building of the present invention, the outer wall heat insulating material 50 may be a board-shaped heat insulating material 30 or an in-situ foamed heat insulating material, and in either case, the heat insulating property of the outer wall portion 20 can be ensured. It can be done, and the degree of freedom of construction is increased.

本発明の建築物の断熱構造の施工方法によれば、建築物の断熱構造１を施工するに際し、第１のセルフレベリング材４０に埋設固定されるボード状断熱材３０は、第１のセルフレベリング材４０が流動性のある状態で敷き込んでボード面３１，３３に平行に移動させながら小口面３２の中間部まで埋設する。
これにより、ボード状断熱材３０の敷き込み時に、単に第１のセルフレベリング材４０の上に敷き並べるのではなく、ボード状断熱材３０を少し前後左右方向にボード面３１，３３と平行に動かしながら、第１のセルフレベリング材４０に押し付けボード状断熱材３０厚さの中間部まで沈めることで、ボード状断熱材３０と第１のセルフレベリング材４０の間の空気を抜き、浮き上がりをなくして密着させることができる。また、ボード状断熱材３０の小口面３２部分に第１のセルフレベリング材４０が廻り込むことでボード状断熱材３０の底面３１だけでなく、小口面３２も接着面として確実に接着固定することができ、剥がれにつながる衝撃力に対するボード状断熱材３０の密着力や固定力を確保することができる。 According to the construction method of the heat insulating structure of the building of the present invention, when the heat insulating structure 1 of the building is constructed, the board-shaped heat insulating material 30 embedded and fixed in the first self-leveling material 40 is the first self-leveling. The material 40 is laid in a fluid state and is buried up to the middle portion of the edge surface 32 while moving in parallel with the board surfaces 31 and 33.
As a result, when the board-shaped heat insulating material 30 is laid, the board-shaped heat insulating material 30 is slightly moved in the front-back and left-right directions in parallel with the board surfaces 31 and 33, instead of simply laying them on the first self-leveling material 40. However, by pressing it against the first self-leveling material 40 and submerging it to the middle part of the thickness of the board-shaped heat insulating material 30, the air between the board-shaped heat insulating material 30 and the first self-leveling material 40 is evacuated, and the floating is eliminated. Can be in close contact. Further, by wrapping the first self-leveling material 40 around the edge surface 32 portion of the board-shaped heat insulating material 30, not only the bottom surface 31 of the board-shaped heat insulating material 30 but also the edge surface 32 is securely adhered and fixed as an adhesive surface. It is possible to secure the adhesive force and the fixing force of the board-shaped heat insulating material 30 against the impact force leading to peeling.
