また、発泡樹脂製の保温板本体の前面または後面のうちの少なくとも一面に嵌合用スリットが形成され、該嵌合用スリットに補強材が取外自在に設置され、前記嵌合用スリットは縦側嵌合用スリットと横側嵌合用スリットとが交差して設けられた保温板とするものである。更に、前記縦側嵌合用スリットと横側嵌合用スリットとの交差部分にのみ平面十字状の補強材を設置して、該補強材を取付用支持具とすることを特徴とするものである。
また保温板の設置方法は、発泡樹脂製の保温板本体の前面または後面のうちの少なくとも一面に嵌合用スリットが形成され、該嵌合用スリットに補強材が取外自在に設置された保温板を堰板とした型枠を形成し、該堰板としての保温板を端太材で支持した後、該端太材で支持された型枠内にコンクリートを打設し、該コンクリートが硬化した後に端太材を撤去して保温板における補強材を嵌合用スリットから取り外すことを特徴とする。
更に、前記本発明に係る保温板を堰板とした型枠を形成し、該堰板としての保温板を端太材で支持した後、該端太材で支持された型枠内にコンクリートを打設し、該コンクリートが硬化した後に端太材を撤去して保温板における補強材を嵌合用スリットから取り外すこととした保温板の設置方法である。 The heat insulating plate for solving the above problems is formed with a fitting slit on at least one of the front surface and the rear surface of the foamed resin heat insulating plate main body, and a reinforcing material is detachably installed in the fitting slit. The fitting slit is a vertical fitting slit formed in a T-shaped cross section along the short side direction of the heat insulating plate body, and the vertical fitting slit having the T-shaped cross section is H A reinforcing member having a shape or a T-shaped reinforcing member is fitted, or the fitting slits are L-shaped cross-sections and are formed as a pair of parallel and back-arranged slits. That is, a reinforcing material in which an L-shaped insertion side is installed or a U-shaped reinforcing material facing each other is fitted into the vertical slit for fitting.
Further, a fitting slit is formed on at least one of the front surface or the rear surface of the foamed resin heat insulating plate body, and a reinforcing material is detachably installed in the fitting slit, and the fitting slit is used for vertical side fitting.

Further, after the concrete is hardened and the formwork is dismantled, it can be pulled out of the slit for fitting the reinforcing material and used for other purposes. Moreover, the reinforcing material of the shape according to a use application can be installed in the slit for fitting of a heat insulating board .

以下、本願発明の保温板および保温板の設置方法の実施の形態について説明する。はじめに保温板の実施の形態について説明し、次に、保温板の設置方法の実施の形態について説明するが、各実施の形態において同じ構成は同じ符号を付して説明し、異なった構成は異なった符号を付して説明する。   Hereinafter, embodiments of the heat insulating plate and the method of installing the heat insulating plate of the present invention will be described. First, an embodiment of the heat insulating plate will be described, and then an embodiment of the method for installing the heat insulating plate will be described. In each embodiment, the same components are described with the same reference numerals, and different configurations are different. A description will be given with reference numerals.

この保温板は鉄筋コンクリート造の躯体の内側に張り付けるものであり、まずは型枠の堰板として使用し、該型枠の解体後には保温板として使用する。   This heat insulating plate is affixed to the inside of a reinforced concrete frame, and is first used as a dam plate for the mold, and is used as a heat insulating plate after the mold is disassembled.

図１〜図４は第１の実施の形態の保温板１である。この保温板１は保温板本体２の一面（前面または後面）に形成された嵌合用スリット３に補強材４が取外自在に嵌め込まれて構成されている。この保温板本体２は厚さ４０ｍｍ以上で、熱抵抗値１．１８ｍ２Ｋ／Ｗ以上を有し、かつ曲げ強さ３５Ｎ／ｃｍ２以上の平面長方形の発泡プラスチック断熱材ボードであり、短辺方向に沿って２本１組の嵌合用スリット３が２３０ｍｍ以下の間隔をもって７本形成され、これに補強材４が取外自在に嵌め込まれている。 1 to 4 show a heat insulating plate 1 according to the first embodiment. The heat insulating plate 1 is configured by a reinforcing member 4 being detachably fitted in a fitting slit 3 formed on one surface (front surface or rear surface) of the heat insulating plate main body 2. This heat insulating plate body 2 is a flat rectangular foamed plastic heat insulation board having a thickness of 40 mm or more, a thermal resistance value of 1.18 m 2 K / W or more, and a bending strength of 35 N / cm 2 or more. A set of two fitting slits 3 is formed along the direction with a spacing of 230 mm or less, and the reinforcing member 4 is detachably fitted therein.

この補強材４は普通軟鋼で垂直片５と水平片６とからなる断面コ字形に形成され、断面二次モーメントが２ｃｍ４以上を有する。したがって、補強材４が保温板本体２の嵌合用スリット３に嵌め込まれたときは、保温板１が補強されるので型枠の堰板として使用されるが、補強材４が嵌合用スリット３から取り外されると、躯体に張り付けられた保温板１として使用される。 This reinforcing member 4 is made of ordinary mild steel and is formed in a U-shaped cross section composed of a vertical piece 5 and a horizontal piece 6 and has a cross-sectional secondary moment of 2 cm 4 or more. Therefore, when the reinforcing material 4 is fitted in the fitting slit 3 of the heat insulating plate main body 2, the heat insulating plate 1 is reinforced, so that the reinforcing material 4 is used as a dam plate. When removed, it is used as a heat insulating plate 1 attached to the housing.

また補強材は、図２の（２）に示すように、断面二次モーメントＩｘが２ｃｍ４以上（弾性率１×１０１１Ｐａ以上）を有するため、この補強材４を嵌合用スリット３に嵌め込んだ保温板１の強度は、たわみ荷重が３ｍｍたわみで約７０ｋｇ以上であり、曲げ弾性率が約１５０ＭＰａ以上となり、型枠の堰板として使用可能になる。 Further, as shown in (2) of FIG. 2, the reinforcing material has a secondary moment of inertia Ix of 2 cm 4 or more (elastic modulus of 1 × 10 11 Pa or more), so that the reinforcing material 4 is fitted in the fitting slit 3. The strength of the heat insulating plate 1 is about 70 kg or more when the deflection load is 3 mm, the bending elastic modulus is about 150 MPa or more, and it can be used as a dam plate for the mold.

また図５〜図７は第２の実施の形態の保温板７である。この保温板７は補強材８が、図に示すように、コ字形の水平片６の先端に折曲片（内側に折り曲げられた）９を備えたものであり、これ以外は第１の実施の形態の保温板１と同じ構成である。   Moreover, FIGS. 5-7 is the heat insulating board 7 of 2nd Embodiment. In this heat insulating plate 7, a reinforcing member 8 is provided with a bent piece (bent inward) 9 at the tip of a U-shaped horizontal piece 6 as shown in the figure. It is the same structure as the heat insulation board 1 of the form.

この補強材４は、図６の（２）に示すように、断面二次モーメントＩＹが２ｃｍ４以上（弾性率１×１０１１Ｐａ以上）を有するため、この補強材４を嵌合用スリット３に嵌め込んだ保温板１の強度は、たわみ荷重が３ｍｍたわみで約７０ｋｇ以上であり、曲げ弾性率が約１５０ＭＰａ以上となり、型枠の堰板として使用可能になる。 As shown in (2) of FIG. 6, the reinforcing member 4 has a secondary moment of inertia I Y of 2 cm 4 or more (elastic modulus 1 × 10 11 Pa or more). The strength of the heat insulating plate 1 fitted in is about 70 kg or more when the deflection load is 3 mm, the bending elastic modulus is about 150 MPa or more, and can be used as a dam plate for a formwork.

また図８および図９は第３の実施の形態の保温板１０である。これは保温板本体２に短辺方向に沿った縦側嵌合用スリット１１と、これに直交した横側嵌合用スリット１２とが形成され、これらの嵌合用スリット１１、１２に補強材１３、１４が嵌め込まれたものであり、これ以外は第１の実施の形態の保温板１と同じ構成である。   8 and 9 show a heat insulating plate 10 according to the third embodiment. The insulating plate body 2 is formed with a longitudinal fitting slit 11 along the short side direction and a transverse fitting slit 12 orthogonal thereto, and the reinforcing slits 13, 14 are provided in the fitting slits 11, 12. Is the same as the heat insulating plate 1 of the first embodiment.

この保温板１０は、図９に示すように、保温板本体２の縦横方向に補強材１３、１４が設置されているため、強度をさらに大きくして、型枠の堰板として使用することができる。この縦側嵌合用スリット１１と、横側嵌合用スリット１２とに嵌め込まれた補強材１３、１４も取外自在である。また、この縦側嵌合用スリット１１の補強材１３を一本にして、横側嵌合用スリット１２の補強材１４を複数に分割することもできる。なお、横側嵌合用スリット１２は、図９のように、１本に限らず、複数本形成することもできる。   As shown in FIG. 9, the heat insulating plate 10 is provided with reinforcing members 13 and 14 in the vertical and horizontal directions of the heat insulating plate main body 2, so that the strength can be further increased and used as a dam plate for a formwork. it can. The reinforcing members 13 and 14 fitted in the vertical side fitting slit 11 and the horizontal side fitting slit 12 are also removable. Further, the reinforcing member 13 of the vertical fitting slit 11 can be divided into a plurality of reinforcing members 14 of the horizontal fitting slit 12. Note that, as shown in FIG. 9, the number of side-side fitting slits 12 is not limited to one, and a plurality of slits may be formed.

また図１０は第４の実施の形態の保温板１５である。この保温板１５は縦側嵌合用スリット１１と横側嵌合用スリット１２との交差部にのみ平面十字状の補強材１６が嵌め込まれたものであり、これ以外は第３の実施の形態の保温板１０と同じ構成である。   FIG. 10 shows a heat insulating plate 15 according to the fourth embodiment. This heat insulating plate 15 is obtained by inserting a planar cross-shaped reinforcing material 16 only at the intersection between the vertical side fitting slit 11 and the horizontal side fitting slit 12, and other than this, the heat insulation plate of the third embodiment. The configuration is the same as that of the plate 10.

この保温板１０は縦側嵌合用スリット１１と横側嵌合用スリット１２に嵌め込まれた補強材１３，１４を取り外した後、特定の交差部に十字状の補強材１６を設置するものであり、この補強材１６を、何かを取り付けるための取付用支持具として使用するものである。   This heat retaining plate 10 is for installing a cross-shaped reinforcing material 16 at a specific intersection after removing the reinforcing materials 13 and 14 fitted in the vertical fitting slit 11 and the horizontal fitting slit 12. This reinforcing material 16 is used as an attachment support for attaching something.

また図１１は第５の実施の形態の保温板１７である。これは保温板本体２の短辺方向に沿って断面Ｔ字形の縦側嵌合用スリット１８を形成し、これにＨ形の補強材１９またはＴ字形の補強材２０を嵌め込んだものであり、これ以外は第１の実施の形態の保温板１と同じ構成である。これは縦側嵌合用スリット１８がＴ字形であるため、保温板本体２の強度を大きくすることができるとともに、補強材１９、２０を縦側嵌合用スリット１８から抜け難くする。   FIG. 11 shows a heat insulating plate 17 according to the fifth embodiment. This is formed by forming a vertical-side fitting slit 18 having a T-shaped cross section along the short side direction of the heat insulating plate body 2 and fitting an H-shaped reinforcing material 19 or a T-shaped reinforcing material 20 therein. Other than this, the configuration is the same as that of the heat insulating plate 1 of the first embodiment. This is because the vertical-side fitting slit 18 has a T-shape, so that the strength of the heat insulating plate body 2 can be increased and the reinforcing members 19 and 20 are not easily removed from the vertical-side fitting slit 18.

また図１２は第６の実施の形態の保温板２１である。これは保温板本体２の短辺方向に沿って断面Ｌ字形の縦側嵌合用スリット２２を一対平行に形成し、これに補強材２３を嵌め込んだものであり、これ以外は第１の実施の形態の保温板１と同じ構成である。   FIG. 12 shows a heat insulating plate 21 according to the sixth embodiment. This is formed by forming a pair of longitudinal fitting slits 22 having an L-shaped cross section along the short side direction of the heat insulating plate main body 2 in parallel, and by inserting a reinforcing material 23 into the slits. It is the same structure as the heat insulation board 1 of the form.

この補強材２３はコ字形の水平片２４の先端が外側に折れ曲がったＬ字形のものであり、保温板本体２の前面との間に僅かな空隙部２５を形成して縦側嵌合用スリット２２に嵌め込まれ、この空隙部２５に充填材２６が充填されている。このように補強材２３が保温板本体２の前面から僅かに突出しているため、この補強材２３に内装材２７を張り付けると、保温板本体２との間に空気層２８を形成することができる。   The reinforcing member 23 is an L-shaped member in which the tip of a U-shaped horizontal piece 24 is bent outward, and a slight gap portion 25 is formed between the front surface of the heat insulating plate main body 2 and a vertical fitting slit 22. The gap 25 is filled with a filler 26. Thus, since the reinforcing material 23 protrudes slightly from the front surface of the heat insulating plate main body 2, when the interior material 27 is attached to the reinforcing material 23, an air layer 28 can be formed between the heat insulating plate main body 2. it can.

また図１３は第７の実施の形態の保温板２９である。これは保温板本体２の前面にＬ字形の縦側嵌合用スリット３０を一対平行で背向配置にして形成するとともに、後面に第１の実施の保温板１同じ形状の嵌合用スリット３を形成し、これらに補強材３１、３２を嵌め込んだものであり、これ以外は第１の実施の形態の保温板１と同じ構成である。 FIG. 13 shows a heat insulating plate 29 according to the seventh embodiment. This is formed with a pair of parallel L-shaped slits 30 on the front side of the heat insulating plate body 2 arranged in parallel and facing backward , and on the rear surface of the heat insulating plate 1 with the same shape as the fitting slit 3. In addition, the reinforcing members 31 and 32 are fitted therein, and the configuration other than this is the same as that of the heat insulating plate 1 of the first embodiment.

また図１３の（１）は、後面側がコ字形の補強材３１であり、前面側が平板にＬ字形差込片が設置された補強材３２である。また同図の（２）における後面はコ字形の補強材３１であり、前面がコ字形の補強材３３を向かい合わせたものである。この保温板２９は保温板本体２の両面に補強材３１、３２、３３が設置されているため、例えば天井に設置すると、補強材３１、３２、３３が照明などの吊下用支持具として使用可能になる。   Further, (1) in FIG. 13 is a U-shaped reinforcing member 31 on the rear side, and a reinforcing member 32 in which an L-shaped insertion piece is installed on a flat plate on the front side. Further, the rear surface in (2) of the figure is a U-shaped reinforcing material 31 and the front surface is a U-shaped reinforcing material 33 facing each other. Since the heat insulating plate 29 is provided with the reinforcing members 31, 32, 33 on both surfaces of the heat insulating plate main body 2, for example, when installed on the ceiling, the reinforcing members 31, 32, 33 are used as hanging supports for lighting or the like. It becomes possible.

次に、保温板の設置方法について、第１の実施の形態の保温板１を用いて説明する。まず、工場などで、嵌合用スリット３に断面二次モーメントＩｘが２ｃｍ４以上の補強材（弾性率１×１０１１Ｐａ以上）４が嵌め込まれた保温板１を製造する。この補強材４は工場で予め嵌合用スリット３に嵌め込んでも良いが、現場において嵌め込ようにしてもよい。 Next, the installation method of a heat insulating board is demonstrated using the heat insulating board 1 of 1st Embodiment. First, at a factory or the like, the heat insulating plate 1 is manufactured in which the reinforcing material (elastic modulus 1 × 10 11 Pa or more) 4 having a sectional secondary moment Ix of 2 cm 4 or more is fitted in the fitting slit 3. The reinforcing material 4 may be fitted in the fitting slit 3 in advance at the factory, but may be fitted on site.

次に、図１４に示すように、この保温板１を堰板として型枠３４を組立形成するが、補強材４が縦側に位置するように組み立てて横側の外端太３５で支持すると、外側の堰板が合板３６で、内側の堰板が保温板１の型枠３４が形成される。このように断面二次モーメントＩｘが２ｃｍ４以上の補強材４を取り付けた保温板１を堰板として使用した型枠３４は、図１５に示すように、水平方向の外端太３５の設置間隔３７を、合板の型枠と同じ設置間隔にすることができる。 Next, as shown in FIG. 14, the formwork 34 is assembled and formed using the heat insulating plate 1 as a dam plate. When the reinforcing material 4 is assembled so as to be positioned on the vertical side and supported by the outer thick end 35 on the horizontal side, The outer dam plate is the plywood 36 and the inner dam plate is the mold 34 of the heat insulating plate 1. As shown in FIG. 15, the formwork 34 using the heat insulating plate 1 to which the reinforcing material 4 having the cross-sectional secondary moment Ix of 2 cm 4 or more is attached as a dam plate, as shown in FIG. 37 can be the same installation interval as the plywood formwork.

次に、この型枠３４内にコンクリートを打設する前に保温板１の上面に、補強材４を覆うように粘着テープ（図示せず）を張る（またはコーキング材でコートする）。これは生コンが保温板１の上面に付着して補強材４が引き抜けなくなるのを防ぐものである。そして、この型枠３４内にコンクリート３８を打設し、このコンクリート３８が硬化した後に、型枠３４を解体すると、躯体３９の内側に保温板１が設置される。そして、この保温板１の上面から粘着テープを除去して、嵌合用スリット３から補強材４を引き抜くと、図１６に示すように、堰板としての役割が終わる。   Next, an adhesive tape (not shown) is applied to the upper surface of the heat insulating plate 1 so as to cover the reinforcing material 4 (or coated with a caulking material) before placing concrete in the mold 34. This prevents raw material from adhering to the upper surface of the heat insulating plate 1 and preventing the reinforcing material 4 from being pulled out. When the concrete 38 is placed in the mold 34 and the mold 38 is disassembled after the concrete 38 is hardened, the heat insulating plate 1 is installed inside the housing 39. Then, when the adhesive tape is removed from the upper surface of the heat insulating plate 1 and the reinforcing member 4 is pulled out from the fitting slit 3, the role as a weir plate ends as shown in FIG.

なお、上記の保温板の設置方法は第１の実施の形態の保温板１を使用したが、その他の第２〜第７の実施の形態の保温板７、１０、１５、１７、２１、２９も同じ方法で設置するものとする。   In addition, although the heat insulation board 1 of 1st Embodiment was used for the installation method of said heat insulation board, the heat insulation board 7, 10, 15, 17, 21, 29 of other 2nd-7th embodiment was used. Shall be installed in the same way.
