Description
【０００１】[0001]
本考案は、構成各部材の厚み関係に制約を受けることなく、断熱性能の向上を 図れ、しかも施工性に優れた木造建築物における断熱構造並びにそれに用いる断 熱板に関する。 The present invention relates to a heat insulating structure in a wooden building which is capable of improving heat insulating performance without being restricted by the thickness relationship of constituent members and has excellent workability, and a heat insulating plate used therefor.
【０００２】[0002]
従来、木造建築物の、例えば床下に断熱構造を構築する場合、間隔をあけて平 行に配設した大引き上に、これらに直交させ、且つ間隔をあけて平行に根太を取 付け、これら根太に断面Ｌ字形の、又は断面コ字形の遊端側に更に側方に遊端片 を延設させた断熱板の取付金具を外嵌させた後、一対の根太間にこの取付金具を 利用して断熱板を嵌込み、更にこの上に床板を根太に釘打ちする等して取付けて いる。 Conventionally, in the case of constructing a heat insulating structure under a floor, for example, in a wooden building, joists are attached to the large pulls arranged in parallel at regular intervals with the joists being orthogonal to and parallel to each other at intervals. After fitting the mounting bracket of the heat insulating plate with the free end piece further extending laterally on the free end side of the L-shaped cross section or the U-shaped cross section, use this mounting bracket between the pair of joists. Then, a heat insulating plate is fitted, and the floor plate is nailed to the joist on it.
【０００３】[0003]
ところが、このような床下の断熱構造では、断熱板の大引き上に載る部分の厚 みとこれの対面側の根太の厚みがほぼ同じである場合でも、根太と断熱板、又断 熱板と床板間には少なくとも取付金具の厚み分に対応した間隙が形成されるから 、断熱性能の面で問題が残る。そして、断熱板は厚みにばらつきが少ないが、根 太は厚みに許容範囲内でのばらつきがあって、仮りに断熱板の大引き上に載る部 分の厚みがこれの対面側の根太の厚みより大きい場合には、床板を根太に取付け ることができないときがあり、又これが逆に小さい場合には、断熱板上面と床板 下面間に取付金具の厚み分以上の間隙が形成され、断熱性能の低下が顕著になる 。 However, in such an underfloor heat insulation structure, even if the thickness of the part of the heat insulation plate that is placed on the large pull and the thickness of the joist on the opposite side are almost the same, the joist and the heat insulation plate, or the heat insulation plate Since a gap corresponding to at least the thickness of the mounting bracket is formed between the floor plates, there remains a problem in terms of heat insulation performance. The thickness of the heat insulating plate varies little, but the thickness of the joists varies within the allowable range.That is, the thickness of the part on the large pull of the heat insulating plate is the thickness of the joists on the facing side. If it is larger, it may not be possible to attach the floorboard to the joist, and if it is smaller, a gap more than the thickness of the mounting bracket is formed between the upper surface of the heat insulating plate and the lower surface of the floor plate, and the heat insulating performance will be increased. Is markedly reduced.
【０００４】 更に、断熱板と根太の厚み関係によっては、床板を根太に取付けることができ ないときがある問題に加えて、一対の根太間への断熱板の嵌込みに先立って、こ れら根太に断熱板の取付金具を所要の間隔をあけて取付ける必要があって、必ず しも施工性に優れるとは言えない。とりわけ、断面Ｌ字形の取付金具を用いると きには、根太に仮止めしなければ、脱落するおそれがあって、作業が面倒である 。Further, depending on the thickness relationship between the heat insulating plate and the joist, in addition to the problem that the floor plate may not be attached to the joist, in addition to the problem that the heat insulating plate is inserted between the pair of joists, Since it is necessary to attach the heat insulating plate mounting brackets to the joists at the required intervals, it cannot always be said that workability is excellent. Especially, when using a mounting bracket having an L-shaped cross section, unless it is temporarily fixed to the joist, it may fall off and the work is troublesome.
【０００５】 こうした従来の問題点に鑑みて考案されたのが本考案に係る木造建築物におけ る断熱構造並びにそれに用いる断熱板で、構成各部材の厚み関係に制約を受ける ことなく、断熱性能の向上を図れ、しかも施工性に優れることを目的とする。In view of such conventional problems, the heat insulating structure and the heat insulating plate used in the wooden building according to the present invention have been devised in view of the heat insulating performance without being restricted by the thickness relationship of the constituent members. It is intended to improve the workability and to have excellent workability.

而して、こうした木造建築物における断熱構造は、例えば床下の断熱構造とし て具体化される。この場合、間隔をあけて平行に配設した木造建築物の構造体で ある大引き上に、これらに直交させ、且つ間隔をあけて平行に下地材となる床板 の取付部材である根太を取付け、これら一対の根太間に、断熱板を長さ方向両側 端の切欠段部を一対の大引きに上方から係止させるとともに、嵌装片を一対の大 引き間の根太下面側に嵌装させて嵌込み、更にこの上に床板を断熱板の取付片を 圧縮変形させて根太に釘打ちする等して取付けるものである。このとき、断熱板 の取付片とこれの対面側の根太の厚み関係に制約を受けることなく、断熱板上面 は床板下面に密接状態になって、断熱性能が良好に維持できる。 Thus, the heat insulating structure in such a wooden building is embodied as a heat insulating structure under the floor, for example. In this case, joists, which are the mounting members of the floorboards that are the base material, are installed in parallel on the large pulls, which are the structures of wooden buildings arranged in parallel with a space between them, at right angles to them.

Then, the floor plate is mounted on the floor plate by compressing and deforming the mounting plate of the heat insulating plate and nailing it to the joist. At this time, the upper surface of the heat insulating plate is in intimate contact with the lower surface of the floor plate without being restricted by the thickness relationship between the attachment piece of the heat insulating plate and the joists on the opposite side, and good heat insulation performance can be maintained.

本考案に係る木造建築物における断熱構造並びにそれに用いる断熱板の詳細を 更に添付の図面に基づき説明する。 Details of a heat insulating structure in a wooden building and a heat insulating plate used therefor according to the present invention will be described with reference to the accompanying drawings.
【００１０】 図示した実施例では、この木造建築物における断熱構造を床下の断熱構造とし て具体化する場合を例示して説明する。In the illustrated embodiment, a case where the heat insulating structure in the wooden building is embodied as an underfloor heat insulating structure will be described as an example.
【００１１】 先ず、図１、２、３中１は木造建築物の構造体である大引きで、これは、例え ば軸心間隔で、通常９００ｍｍ程度あけて平行に配設されている。そして、これ は、通常９０ｍｍ角の角柱状に形成されたものが用いられる。First, reference numeral 1 in FIGS. 1, 2, and 3 denotes a large structure, which is a structure of a wooden building, and is arranged, for example, at an axial center interval, usually about 900 mm in parallel. And, as this, one formed in a prism shape of 90 mm square is usually used.
【００１２】 次に、２はこの大引き１上に、これらに直交させ、且つ、例えば軸心間隔で、 通常３００〜４５０ｍｍ程度あけて平行に釘打ちする等して取付けた下地材とな る床板の取付部材である根太を示している。これは、通常４５ｍｍ角の角柱状に 形成されたものや４５ｍｍ×６０ｍｍ角の偏平角柱状に形成されたものが用いら れる。Next, 2 is a base material which is mounted on the pulling wire 1 so as to be orthogonal to these and to be nailed in parallel with each other, for example, with an axial distance of 300 to 450 mm. The joist which is an attachment member of a floor board is shown. This is usually used in the form of a 45 mm square prism, or in the form of a 45 mm × 60 mm square flat prism.
【００１３】 又、図中３は長さ方向両端を一対の大引き１、１に係止させて、一対の根太２ 、２間に嵌込まれる断熱板である。これは、通常、硬質発泡合成樹脂体から作成 されたものが用いられる。Reference numeral 3 in the drawing denotes a heat insulating plate which is fitted between the pair of joists 2 and 2 by locking both ends in the length direction to the pair of large pulls 1 and 1. This is normally made of a rigid foam synthetic resin body.
【００１４】 更に、４は根太２と断熱板３上に根太２に釘打ちする等して取付けた下地材と なる床板である。Further, 4 is a floor plate serving as a base material attached to the joist 2 and the heat insulating plate 3 by nailing the joist 2 or the like.
【００１５】 この床板４は、フローリング材等のように表面に仕上げ加工が施されているも のを用いる場合には、このまま表面材となるが、表面に仕上げ加工が施されてい ないものを用いるときには、この上にクッションフロアー又はカーペット等の表 面材が適宜、設けられる。When a flooring material such as a flooring material whose surface is finished is used, the floor board 4 is a surface material as it is, but a surface finishing material is not used. Occasionally, a surface material such as a cushion floor or carpet is appropriately provided on this.
【００１６】 そして、断熱板３は図１、２、３に示すように本体10の図１中Ａとして示す長 さ方向両側端の同じくＢとして示す幅方向に相対向させて側端側と一方の表面側 に開放した構造体である大引き１に係止させるための切欠段部11、11を設けると ともに、この切欠段部11を設けた部分に厚みａがこれの対面側の根太２の厚みよ り大きく、しかも圧縮変形可能な取付片12、12を形成し、又切欠段部11を設けた 直交方向の側端の一方に一対の大引き１、１間の根太２下面側に嵌装される嵌装 片13を形成したものである。ここに示すのは、嵌装片13を根太２下面側から更に 突出する長さに形成するとともに、これを設けた反対側の側端の他方に他の断熱 板３の嵌装片13の根太２下面側から突出した先端側を内装する側端側と一方の表 面側に開放した内装段部14を形成したものである。尚、取付片12の切欠段部11側 と嵌装片13の根太２下面の対面側はほぼ同一面上になるように形成したり、又は 両者間に間隔があくように形成するものである。As shown in FIGS. 1, 2 and 3, the heat insulating plate 3 is opposed to the side ends of the main body 10 in the widthwise direction at both ends in the lengthwise direction shown as A in FIG. Notch step portions 11 and 11 are provided on the front surface side for locking the large pulling 1 which is an open structure, and at the portion where the notch step portion 11 is provided, the thickness a has a joist 2 on the opposite side. Of the pair of large pulls 1 and 1 between the joists 2 on one side of the side edges in the orthogonal direction where the mounting pieces 12, 12 that are larger than the thickness of the The fitting piece 13 to be fitted is formed. Here, the fitting piece 13 is formed to have a length that further protrudes from the bottom surface side of the joist 2 and the joist of the fitting piece 13 of the other heat insulating plate 3 is formed on the other side end on the opposite side where the fitting piece 13 is formed. (2) An inner step portion 14 is formed on the side end side which projects the tip side protruding from the lower surface side and which is open on one surface side. The notch step portion 11 side of the mounting piece 12 and the facing side of the bottom surface 2 of the joist 2 of the fitting piece 13 are formed so as to be substantially on the same plane, or there is a space between them. ..
【００１７】 又、断熱板３は、その取付け状態から剛性を備えた、通常、密度が５〜３５ｋ ｇ／ｍ3 、圧縮弾性率が１〜６０ｋｇ／ｃｍ2 の範囲内にある、例えば発泡ポリ スチレン４０倍成形品等の硬質発泡合成樹脂体から作成されたものが用いられる が、これに設けた取付片12は圧縮変形可能にするため、図４、５に示すように取 付片12の幅方向に側端から一対の表面と平行に切欠段部11の深さｂより深い開口 幅を有する凹溝15を形成するとともに、取付片12の折曲変形をも可能とするため 、取付片12の基端にも更に切欠段部11を構成する面に沿った凹溝16を形成してい る。こうした断熱板３に凹溝15、16を形成するのは、前記したように圧縮弾性率 が１〜６０ｋｇ／ｃｍ2 の範囲内にある、例えば発泡ポリスチレン４０倍成形品 等の硬質発泡合成樹脂体では、弾性変形性に乏しく、加工を施さなければ、意図 する断熱板３上面と根太２に取付ける床板４下面が密接状態にならないからであ る。ところで、取付片12の切欠段部11側と嵌装片13の根太２下面の対面側がほぼ 同一面上になるように形成されている場合、取付片12の基端側に設ける凹溝16は 取付片12の部分だけに形成しても、又は嵌装片13の部分に段部として残るように 形成してもいずれでもよい。Further, the heat insulating plate 3 has rigidity from the attached state, and usually has a density of 5 to 35 kg / m 3 and a compression elastic modulus of 1 to 60 kg / cm 2 , for example, a foamed poly A styrene 40 times molded product such as a molded product made of hard foam is used. The mounting piece 12 provided on this is compressed and deformable. Therefore, as shown in Figs. A groove 15 having an opening width deeper than the depth b of the notch step 11 is formed parallel to the pair of surfaces in the width direction from the side end, and the mounting piece 12 can be bent and deformed. A concave groove 16 is further formed on the base end of 12 along the surface forming the notch step portion 11. The concave grooves 15 and 16 are formed in the heat insulating plate 3 as described above, for example, a hard foam synthetic resin body such as a polystyrene foam 40 times molded product having a compression elastic modulus within the range of 1 to 60 kg / cm 2. Then, since the elastic deformation is poor, the intended upper surface of the heat insulating plate 3 and the lower surface of the floor plate 4 attached to the joist 2 are not brought into close contact with each other unless they are processed. By the way, when the notch step portion 11 side of the mounting piece 12 and the facing side of the bottom surface 2 of the joist 2 of the fitting piece 13 are formed to be substantially on the same plane, the concave groove 16 provided at the base end side of the mounting piece 12 is It may be formed only on the portion of the mounting piece 12 or may be formed so as to remain as a step on the portion of the fitting piece 13.
【００１８】 これら凹溝15、16の開口幅ｃ1 、ｃ2 は、用いる根太２そのものの厚み、又は 用いる根太２の向きに応じた大引き１上での厚み、設ける数、深さ、更には断熱 板３素材の発泡倍率等によって若干変化するが、４５ｍｍ角の角柱状に形成され た根太２を用いた場合、それぞれ２〜３ｍｍ程度、二条の凹溝15、16の開口幅ｃ 1 とｃ2 の合計が５ｍｍ程度が好適であった。又、取付片12の厚みａは、この場 合、４６〜４８ｍｍ程度に形成される。こうしたことから、取付片12の厚みａは 根太２の断熱板３の対面側の厚みのほぼ１．０３〜１．２０倍程度に形成される のが好ましいと言える。因みに、断熱板３は全体厚みｄが４７〜１００ｍｍ程度 の範囲内にあるものが、通常、用いられる。更に、凹溝15、16の深さＬ1 、Ｌ2 は１〜２００ｍｍ、好ましくは４５〜２００ｍｍ、更に好ましくは９０〜１１０ ｍｍの範囲内に形成される。そして、実験の結果によれば、図４、５に示すよう に凹溝15、16を二条設けた場合、図示したように取付片12の切欠段部11を構成す る面に沿った凹溝16と他方の凹溝15の側端からの溝底位置をほぼ同一に、又は凹 溝16を凹溝15より深くすると、取付片12の圧縮変形、更には折曲変形が良好に行 えることが判った。即ち、これら二条の凹溝15、16の深さ関係は図４、５に示す ようにＬ2 ≧Ｌ1 とすれば、良好になることが判ったのである。又、取付片12の 突出長さ、即ち前記した切欠段部11の深さｂは大引き１の厚みの１／２程度、又 はそれよりわずかに大きい程度に形成される。The opening width c of these concave grooves 15 and 161, C2Is slightly different depending on the thickness of the joist 2 itself, or the thickness of the joist 2 depending on the direction of the joist 2 used, the number to be provided, the depth, and the foaming ratio of the material of the heat insulating plate 3. When using the joist 2 formed in the prismatic shape, the opening width c of the two recessed grooves 15 and 16 is about 2 to 3 mm, respectively. 1 And c2Was about 5 mm. Further, in this case, the thickness a of the mounting piece 12 is formed to be about 46 to 48 mm. From this, it can be said that the thickness a of the attachment piece 12 is preferably formed to be approximately 1.03 to 1.20 times the thickness of the heat insulating plate 3 of the joist 2 on the opposite side. Incidentally, the heat insulating plate 3 having a total thickness d within the range of about 47 to 100 mm is usually used. Further, the depth L of the grooves 15 and 161, L2 Is formed in the range of 1 to 200 mm, preferably 45 to 200 mm, and more preferably 90 to 110 mm. According to the result of the experiment, when two grooves 15 and 16 are provided as shown in FIGS. 4 and 5, the grooves along the surface forming the notch step portion 11 of the mounting piece 12 as shown in the drawing. If the groove bottom positions from the side ends of the 16 and the other concave groove 15 are substantially the same, or if the concave groove 16 is deeper than the concave groove 15, the mounting piece 12 can be satisfactorily compressed and bent. I understood. That is, the depth relationship between these two grooves 15 and 16 is L as shown in Figs.2≧ L1Then, it turns out that it will be good. Further, the protruding length of the mounting piece 12, that is, the depth b of the notch step portion 11 is formed to be about ½ of the thickness of the pull 1 or slightly larger than it.
【００１９】 而して、こうした床下の断熱構造は、間隔をあけて平行に配設した木造建築物 の構造体である大引き１上に、これらに直交させ、且つ間隔をあけて平行に下地 材となる床板４の取付部材である根太２を取付け、これら一対の根太２、２間に 、断熱板３を長さ方向両側端の切欠段部11、11を一対の大引き１、１の上方から 係止させるとともに、嵌装片13を一対の大引き１、１間の根太２下面側に嵌装さ せ、しかもこの嵌装片13の根太２下面側から突出した先端側を他の断熱板３の内 装段部14に内装させて嵌込み、この上に床板４を断熱板３の取付片12に設けた凹 溝15の開口側の開口幅を収縮させることで圧縮変形させるとともに、他の凹溝16 の開口側の開口幅を収縮させることで折曲変形させたり、場合によっては取付片 12を弾性変形又は塑性変形させて根太２に釘打ちする等して取付けて構築される ものである。このとき、断熱板３の取付片12とこれの対面側の根太２の厚み関係 に制約を受けることなく、断熱板３上面は床板４下面に密接状態になる。ここで 、取付片12の突出長さ、即ち切欠段部11の深さｂと大引き１の厚みとの関係や施 工上の問題から、取付片12、12間に間隙が形成されたとしても、この間隙は床板 ４と根太２で上下から閉止されて、完全な密閉空間又は半密閉空間となるから、 断熱性能を低下させる原因にはならない。更に、こうした断熱構造を構築する場 合、大引き１の施工後の手順を根太２と断熱板３を交互に取付けるようにすると 、根太２と断熱板３をより密接状態にできる。Thus, such an underfloor heat insulating structure is provided on a large pulling 1 which is a structure of a wooden building arranged in parallel at a distance from each other so as to be orthogonal to them and to be ground in parallel at a distance. A joist 2 which is an attachment member of a floor board 4 as a material is attached, and a heat insulating board 3 is provided between the pair of joists 2 and 2 with cutout steps 11 and 11 at both ends in the length direction of the pair of large pulls 1 and 1. The fitting piece 13 is fitted onto the lower surface side of the joist 2 between the pair of large pulls 1 and 1, and the tip side of the fitting piece 13 protruding from the lower surface side of the joist 2 is attached to the other side. The floor board 4 is compressed and deformed by shrinking the opening width on the opening side of the recessed groove 15 provided in the mounting piece 12 of the heat insulating plate 3 by fitting it on the inner mounting step portion 14 of the heat insulating plate 3. , It may be bent and deformed by shrinking the opening width of the other groove 16 on the opening side, or the mounting piece 12 may be elastic It is constructed by deforming or plastically deforming and nailing the joist 2 or the like. At this time, the upper surface of the heat insulating plate 3 comes into close contact with the lower surface of the floor plate 4 without being restricted by the thickness relationship between the attachment piece 12 of the heat insulating plate 3 and the joist 2 on the opposite side thereof. Here, because of the projecting length of the mounting piece 12, that is, the relationship between the depth b of the notch step portion 11 and the thickness of the large pull 1 and processing problems, a gap may be formed between the mounting pieces 12, 12. However, this gap is closed from above and below by the floor plate 4 and the joist 2 to form a completely enclosed space or a semi-enclosed space, and therefore does not cause a decrease in heat insulation performance. Further, in the case of constructing such a heat insulating structure, if the joist 2 and the heat insulating plate 3 are alternately attached in the procedure after the construction of the large pulling 1, the joist 2 and the heat insulating plate 3 can be brought into closer contact with each other.
【００２０】 図示した実施例において、取付片12の基端側の切欠段部11を構成する面に沿っ た状態で形成される凹溝16は適宜、省略することも可能である。この場合、取付 片12に設ける凹溝15の開口幅を相対的に大きくすることで、取付片12の圧縮変形 を充分な状態に対処させる。又、取付片12に設ける凹溝15は二条以上の複数、平 行に設けることもできる。In the illustrated embodiment, the concave groove 16 formed along the surface of the notch step portion 11 on the base end side of the mounting piece 12 can be omitted as appropriate. In this case, by making the opening width of the concave groove 15 provided in the mounting piece 12 relatively large, the compressive deformation of the mounting piece 12 can be dealt with in a sufficient state. Further, the recessed groove 15 provided in the mounting piece 12 can be provided in a plurality of two or more rows and in a horizontal direction.
【００２１】 更に、圧縮変形可能な取付片12は、図６に示すように取付片12の切欠段部11側 に圧縮変形可能な軟質合成樹脂体、又は軟質発泡合成樹脂体、更には海綿、軟質 ゴム等から形成される弾性体17をこの面全体に又は適宜間隔をあけて貼着して設 けることもできる。この場合、取付片12の全体厚みｅは根太２の断熱板３との対 面側より大きくなるように形成するのであるが、この部分の断熱板３自体の厚み はこれと同一でも、又は小さくしてもいずれでもよい。Further, the compression-deformable mounting piece 12 is, as shown in FIG. 6, a soft synthetic resin body that is compression-deformable on the notch step 11 side of the mounting piece 12, or a soft foam synthetic resin body, and further a sponge, An elastic body 17 formed of soft rubber or the like can be attached to the entire surface or by adhering it at appropriate intervals. In this case, the total thickness e of the mounting piece 12 is formed so as to be larger than the side of the joist 2 facing the heat insulating plate 3, but the thickness of the heat insulating plate 3 itself at this portion may be the same or smaller. Either or both may be used.
【００２２】 そして、凹溝15、16と弾性体17の両者を組合せることも、適宜考慮される。Then, combining both the concave grooves 15 and 16 and the elastic body 17 is also considered as appropriate.
【００２３】 又、図７に示すように断熱板３の一対の大引き１、１間に嵌込まれる部分に平 行な開口幅を有するスリット18…を形成することも可能である。このときには、 この部分が特に伸縮効果で一対の大引き１、１間に密接状態となって、断熱性能 をより向上させることができる。Further, as shown in FIG. 7, it is possible to form slits 18 having a flat opening width in a portion fitted between the pair of large pulls 1 and 1 of the heat insulating plate 3. At this time, this portion is brought into close contact with the pair of large pulls 1 and 1 due to the expansion and contraction effect, so that the heat insulating performance can be further improved.
【００２４】 次に、図８には断熱板３の切欠段部11を設けた直交方向の側端の他方に設ける 内装段部14の嵌装片13の挿入側の深さを嵌装片13の突出長さと比較して深くした ものを示している。この場合、断熱板３の本体10の厚みは結果として相対的に小 さくなるが、これで充分な断熱性能が達成されるなら、使用樹脂量が少なくなっ て、好ましいものと言える。Next, in FIG. 8, the depth on the insertion side of the fitting piece 13 of the internal stepped portion 14 provided at the other side end of the heat insulating plate 3 in the orthogonal direction where the cutout step portion 11 is provided It shows a deeper part compared to the protruding length of. In this case, the thickness of the main body 10 of the heat insulating plate 3 becomes relatively small as a result, but if sufficient heat insulating performance is achieved by this, the amount of resin used will be small, which is preferable.
【００２５】 又、嵌装片13は根太２下面側にだけ対応する長さに形成することも可能である 。このとき、これと反対側の側端の他方に内装段部14を必ずしも設ける必要はな い。Further, the fitting piece 13 can be formed with a length corresponding only to the lower surface side of the joist 2. At this time, the interior step 14 does not necessarily have to be provided on the other side end on the opposite side.
【００２６】 更に、側端の双方に嵌装片13を形成することもできる。Further, the fitting pieces 13 can be formed on both of the side ends.
【００２７】 次に、図９には図１、２、３に示す断熱板３を幅方向に二つ並設させたものを 示している。Next, FIG. 9 shows two heat insulating plates 3 shown in FIGS. 1, 2 and 3 arranged side by side in the width direction.
【００２８】 そして、大引き１、根太２は図示した実施例で示されたものの他、種々の態様 のものを、適宜間隔をあけて配設させることも可能である。The pulling wire 1 and the joist 2 may be of various types other than those shown in the illustrated embodiment, and may be arranged at appropriate intervals.
【００２９】 又、断熱板３も硬質発泡合成樹脂体から形成されたものの他、種々のものが利 用できる。Also, the heat insulating plate 3 may be made of various materials other than the one made of a hard foam synthetic resin body.
【００３０】 更に、嵌装片13上に予め根太２を一体に装着しておくことも適宜考慮される。Further, it may be appropriately considered to integrally attach the joist 2 on the fitting piece 13 in advance.
【００３１】 又、こうした木造建築物における断熱構造は、この他、屋根裏の断熱構造とし て具体化することも可能である。Further, the heat insulating structure in such a wooden building can also be embodied as a heat insulating structure for the attic.
【００３２】[0032]
以上のような本考案に係る木造建築物における断熱構造では、従来のものと比 較して、断熱板の取付金具を用いないから、これの厚み分に対応した間隙が形成 されず、又構成各部材、とりわけ断熱板の取付片とこれの対面側の取付部材の厚 み関係に制約を受けることなく、常に断熱板と下地材が密接状態になって、断熱 性能が向上する。又、断熱板の取付金具が不要になるのに加えて、断熱板と取付 部材の厚み関係によっては、下地材を取付部材に取付けることができない問題も なくなり、施工性が優れたものとなる。これによって、工期の短縮を図ることも 容易になる。 In the heat insulation structure for a wooden building according to the present invention as described above, compared with the conventional structure, since the mounting bracket of the heat insulation plate is not used, the gap corresponding to the thickness thereof is not formed, and the structure Regardless of the thickness relationship between each member, especially the mounting piece of the heat insulating plate and the mounting member on the opposite side, the heat insulating plate and the base material are always in close contact with each other to improve the heat insulating performance. In addition to eliminating the need for a mounting bracket for the heat insulating plate, there is no problem that the base material cannot be mounted on the mounting member depending on the thickness relationship between the heat insulating plate and the mounting member, and the workability is excellent. This makes it easier to shorten the construction period.
【００３３】 更に、これに用いる断熱板は長さ方向両側端に相対向させて切欠段部を設ける とともに、この切欠段部を設けることで形成される取付片に凹溝を設けたり、弾 性体を貼着し、又これと直交方向の側端の一方に嵌装片を形成しただけのもので あるから、加工も容易に行える。Further, the heat insulating plate used for this is provided with notched step portions at both ends in the length direction so as to face each other, and a mounting groove formed by providing the notched step portions is provided with a concave groove or is elastic. Since the body is simply attached and the fitting piece is formed on one of the side ends in the direction orthogonal to the body, the processing can be easily performed.
【００３４】 そして、従来のものと比較して、断熱板の加工が付加されるが、断熱板の取付 金具の取付けが全く不要になるから、施工費用が上昇することもないのである。Further, as compared with the conventional one, the heat insulating plate is added, but since the attachment of the heat insulating plate mounting member is completely unnecessary, the construction cost is not increased.
