Description

この発明は、コンクリート構造物を構築するコンクリート打設に使用されるコンクリート型枠装置、特に言えば鋼製で断熱構造のコンクリート型枠装置と、前記コンクリート型枠装置に必要な断熱性能を確保する目的で型枠へ取り付けられる断熱成形体、および前記断熱成形体を採用した断熱コンクリート型枠装置の組み立て方法の技術分野に属する。 The present invention secures a concrete formwork apparatus used for placing concrete to construct a concrete structure, in particular, a concrete formwork apparatus made of steel and having a heat insulation structure, and a heat insulation performance necessary for the concrete formwork apparatus. The present invention belongs to the technical field of a heat insulating molded body attached to a mold for the purpose and a method for assembling a heat insulating concrete mold apparatus employing the heat insulating molded body.

コンクリート打設にあたっては、寒冷期のコンクリートの保温養生、また、夏期のコンクリートの温度上昇に対する適切な保温養生が重要である。特に鋼製型枠の場合は、鋼材の熱伝導率が高いので、前記した外気温の高低に対する対策が特に重要視される。
そこで従来の対策は、鋼製型枠に発熱体や断熱材を設置してコンクリート打設時の温度の悪影響を緩和する手法が提案され、実施もされている。 When placing concrete, it is important to keep the concrete warm during the cold season and to keep the concrete warm against the temperature rise during the summer. In particular, in the case of a steel mold, since the thermal conductivity of the steel material is high, the countermeasures against the above-described high and low outside air temperatures are particularly emphasized.
Therefore, a conventional measure has been proposed and implemented as a method for reducing the adverse effect of temperature at the time of placing concrete by installing a heating element or a heat insulating material on a steel mold.

例えば下記の特許文献１に記載された型枠は、鋼製型枠本体の外側に、通電することにより発熱する面状発熱体を設けることで保温効果を発揮させ、寒冷地における冬期のコンクリート打設における外気温の悪影響を緩和してひび割れの防止を図る、と説明されている。
また、下記の特許文献２に記載された断熱型枠は、地下にコンクリート壁を構築する場合に埋め殺し用として使用する特殊用途の型枠であるが、鋼製型枠に断熱材を取り付けた構成が提案されている。前記断熱材は、例えば接着剤を用いて貼り付けると記載されている（同公報の例えば段落番号［００１６］）。 For example, the mold described in Patent Document 1 below provides a heat-generating effect by providing a sheet heating element that generates heat when energized on the outside of a steel mold body. It is explained that the adverse effect of the outside air temperature in the facility is mitigated to prevent cracking.
Moreover, although the heat insulation formwork described in the following patent document 2 is a special use formwork used for burying when a concrete wall is constructed underground, a heat insulating material is attached to a steel formwork. A configuration is proposed. It is described that the heat insulating material is attached using, for example, an adhesive (for example, paragraph number [0016] of the same publication).

特開平８−２１０８７号公報JP-A-8-21087 特開２００１−３５６４号公報JP 2001-3564 A

上記特許文献１に開示された型枠は、鋼製型枠本体の外側に、通電することにより発熱する面状発熱体を設けた構成なので、寒冷地における冬期のコンクリート打設にはそれなりの保温効果を発揮するであろうと推定できる。
また、上記特許文献２に開示された断熱型枠は、地下にコンクリート壁を構築する場合に埋め殺し用として使用する特殊な用途である点はさておき、鋼製型枠の背面の周縁部に沿って立てた周辺リブに、当該鋼製型枠同士を横並びに連結するための連結孔を設けた構成を前提に、同連結用孔を利用するボルトやフックを通す作業の邪魔にならないように、同周辺リブとの間に一定の隙間を形成する幅および高さに構成した断熱材を設置すると説明されている（同公報の例えば段落番号［００１６］）。そして、前記の隙間は、鋼製型枠の背面の周縁部に沿って立てた周辺リブの全周にわたり設ける構成が、図１ないし図３の記載から明らかである。
前記隙間の大きさについて具体的な記載は見当たらない。しかし、同隙間が連結用孔を利用するボルトやフックを通す作業の邪魔にならないようにするためであることを考慮すれば、少なくとも５０ｍｍ〜１００ｍｍ程度は必要になるであろう。そうすると鋼製型枠の面板に、前記の如き断熱材の不存在箇所（隙間）を生じさせることは明らかであり、そのような断熱材不存在箇所を設けた構成では、打設コンクリートの特定の局部に温度が高いか又は低い部分を生じさせることとなり、かえって養生効果を害する欠陥をもたらすと云わねばならない。 Since the formwork disclosed in Patent Document 1 has a structure in which a sheet-like heating element that generates heat when energized is provided outside the steel formwork body, it is suitable for concrete placement in winter in cold regions. It can be estimated that it will be effective.
Moreover, the heat insulation formwork disclosed in the above-mentioned Patent Document 2 is a special application used for burying when constructing a concrete wall in the basement, aside from the peripheral edge of the back of the steel formwork. Assuming that the peripheral ribs are provided with connecting holes for connecting the steel molds side by side, the bolts and hooks that use the connecting holes are not disturbed. It is described that a heat insulating material configured to have a width and height that form a certain gap with the peripheral rib is installed (for example, paragraph [0016] of the same publication). And the structure which provides the said clearance gap over the perimeter of the peripheral rib stood along the peripheral part of the back surface of steel molds is clear from description of FIG. 1 thru | or FIG.
There is no specific description about the size of the gap. However, considering that the gap does not interfere with the operation of passing the bolts and hooks using the connection holes, at least about 50 mm to 100 mm will be necessary. Then, it is clear that the above-mentioned non-existing portion (gap) of the heat insulating material is generated in the face plate of the steel formwork. In the configuration in which such an insulating material non-existing portion is provided, a specific part of the cast concrete is provided. It must be said that locally high or low temperature portions are produced, and defects that adversely affect the curing effect are caused.

本発明の目的は、コンクリート型枠を使用して打設したコンクリートの養生に必要な断熱性能を全面的に等しく発揮して、コンクリート打設時の外気温の悪影響を緩和する断熱コンクリート型枠装置を提供することである。即ち、コンクリート型枠の面板の背面側に断熱材を取り付ける場合に、面板の全面に断熱材が等しく行き渡り、断熱効果を面板の全面にわたり等しく期待でき、打設コンクリートに良好な養生効果を期待できる断熱コンクリート型枠装置を提供することである。
本発明の目的は、面板の全面に断熱材が行き渡り、断熱効果を面板の全面にわたって等しく期待でき、打設コンクリートの良好な養生効果を期待できることは当然として、コンクリート型枠の組み立て、使用に不可欠であるフックボルトの取り付け、或いはクリップによる型枠相互間の接合の作業に一切支障のない構成の断熱コンクリート型枠装置を提供することである。
本発明の次の目的は、コンクリート型枠装置に必要な断熱保温の性能を確保するべく型枠へ取り付け又は取り外すことが容易に行え、また、型枠への取り付け又は取り外しの時期に制約がなく、しかも事後的に必要に応じ適宜に加工して使用することに適するなど、使い勝手の良い断熱成形体を提供することである。
本発明の更なる目的は、前記断熱成形体を採用した断熱コンクリート型枠装置の組み立て方法を提供することである。 An object of the present invention is to provide a heat insulating concrete formwork device that can exert the same overall heat insulation performance necessary for curing concrete placed using a concrete formwork to alleviate the adverse effects of outside air temperature during concrete placement.

以下に、本発明を図示した実施例に基づいて説明する。
本発明の断熱コンクリート型枠装置１０は、一例を図１に示した鋼製型枠１を主体とし、これに図３、図４に示した断熱成形体２を組み合わせて構成する。
図１に示した鋼製型枠１は、一例として幅×長さが３０×１５０ｃｍの大きさである鋼製面板１ａの背面側に、同面板１ａの外周縁に沿って立つ周辺リブ（縦リブ１ｂ、横リブ１ｃ）と、同周辺リブ１ｂ、１ｃで囲まれた枠内を縦、横方向に仕切る中リブ（中縦リブ１ｄ、中横リブ１ｅ）とを備えて、打設したコンクリートの圧力に耐える剛強な構成とされている。
図１の場合は、幅３０ｃｍの面板１ａの中央部に１本の中縦リブ１ｄを配置しており、長さ１５０ｃｍの面板１ａの長手方向には中横リブ１ｅを、先ず両端から１５ｃｍずつの位置に１本ずつ配置して両端寄りに１５ｃｍ×１５ｃｍの正方形の枡４、４を形成し、長さ方向の中間には３０ｃｍの間隔で３本の中横リブ１ｅを配置して、１５ｃｍ×３０ｃｍの長方形の枡４’を４個ずつ２列に形成した構成とされている。
但し、面板１ａの幅寸が例えば１５ｃｍの場合は、前記中縦リブ１ｄは無いので、中横リブ１ｅのみを設置した構成で実施される。逆に、図５に示したように幅寸が大きい場合には、必要に応じて中縦リブ１ｄを３本、等間隔をあけて平行に設置した構成も同様に実施される。各リブのせいの高さは５５ｍｍである。
上記横方向のリブ１ｃ、１ｅには、フックボルトを取り付ける取付孔１ｆが設けられる。また、縦方向のリブ１ｂ、１ｄにはＵクリップ（又はボルト、ナットの場合もある。以下同じ。）を取り付ける取付孔１ｇがそれぞれ、後述する枡１個につき縦、横の辺に少なくとも１個ずつの割合で設けられている。 Hereinafter, the present invention will be described based on illustrated embodiments.
The heat insulating concrete formwork apparatus 10 of the present invention is mainly composed of the steel formwork 1 shown in FIG. 1 and is combined with the heat insulating formed body 2 shown in FIGS. 3 and 4.
As an example, the steel formwork 1 shown in FIG. 1 has peripheral ribs (vertical lengths) standing on the back side of a steel face plate 1a having a width × length of 30 × 150 cm along the outer periphery of the same face plate 1a. Ribs 1b, horizontal ribs 1c), and medium ribs (medium vertical ribs 1d, medium horizontal ribs 1e) that divide the frame surrounded by the peripheral ribs 1b, 1c vertically and horizontally. It has a strong structure that can withstand the pressure of.
In the case of FIG. 1, one middle longitudinal rib 1d is arranged at the center of the face plate 1a having a width of 30 cm. The middle transverse rib 1e is first placed 15 cm from both ends in the longitudinal direction of the face plate 1a having a length of 150 cm. Are arranged one by one at the positions of the square ridges 4, 4 of 15 cm × 15 cm near the both ends, and three medium lateral ribs 1 e are arranged at intervals of 30 cm in the middle of the length direction, The configuration is such that four rectangular ridges 4 'each having a size of 30 cm are formed in two rows.
However, when the width dimension of the face plate 1a is, for example, 15 cm, the middle vertical rib 1d is not provided, and therefore, the configuration is implemented with only the middle horizontal rib 1e. On the other hand, when the width is large as shown in FIG. 5, a configuration in which three middle longitudinal ribs 1d are installed in parallel at equal intervals as necessary is similarly implemented. The height of each rib is 55 mm.
The lateral ribs 1c and 1e are provided with attachment holes 1f for attaching hook bolts. Further, at least one mounting hole 1g for attaching a U-clip (or a bolt or a nut; the same applies hereinafter) to the vertical ribs 1b and 1d, respectively, on the vertical and horizontal sides of each flange described later. It is provided at a rate of one by one.

上記した鋼製型枠１の面板１ａの背面に設置した周辺リブ（縦リブ１ｂ、横リブ１ｃ）と中リブ（中縦リブ１ｄ、中横リブ１ｅ）とで複数に区画された矩形の枡４（又は４’、以下同じ）の中に、後述する構成の断熱成形体２が１個又は２個を一組として嵌め込まれて、面板１ａの背面の全面を断熱材で覆った断熱コンクリート型枠装置１０が構成されている。正方形の枡４の大きさは、面板１ａの上記寸法例に従って１５ｃｍ×１５ｃｍの大きさとされており、断熱成形体２は、一つの枡４に１個の割合で嵌め込まれる。一方、上記長方形の枡４’（１５ｃｍ×３０ｃｍ）には、同形、同大の２個の断熱成形体２、２を一対の配置に組み合わせて嵌め込む。つまり、正方形の枡４と長方形の枡４’にはそれぞれ、図４ａに示す正方形の断熱成形体２が共通に使用される。
図示した断熱成形体２は、ＪＩＳＡ９５１１：２００６Ｒで測定した熱伝導率が０．０２〜０．０６Ｗ／（ｍ・Ｋ）、ＡＳＴＭＥ−９６で測定した透湿度が０．０３〜０．１０ｇ／（ｍ・時）の性能を有する、コンクリートやモルタルが付着し難いポリエチレン又はポリプロピレン、ポリスチレンとポリオレフィン複合樹脂等による独立気泡発泡樹脂成形体を、上記枡４の大きさにしたがい、図４ａに示す背面形状が、縦×横寸法を１５０×１５０ｍｍの正方形とし、厚さが２５ｍｍ前後に成形した構成で使用される。
因みに、断熱成形体２の厚さに関しては、少なくとも１０ｍｍ〜１５ｍｍあれば、鋼製型枠１の面板１ａに必要な断熱保温効果を発揮することが確認された。そこで各リブのせいの高さが上記の通り５５ｍｍであることを考慮して、同リブの高さの約半分相当の厚さ２５ｍｍ前後に構成すると、鋼製型枠１によるコンクリート打設における養生に有効的である。しかし、リブの高さ５５ｍｍに対して、断熱成形体２の厚さが２５ｍｍであると、リブの約３０ｍｍ分が外気に晒され、それが入熱又は放熱の原因となることを考慮すると、経済性が許す限り、断熱成形体２の厚さは少なくともリブの高さと等しく形成して実施するのが良い。例えば鋼製型枠１のリブが形成する枡４又は４’の中へ上記構成の断熱成形体２を二重層に嵌め込むと丁度リブの高さに等しい断熱材で覆うことになって好都合である。リブの高さより大きい厚さの断熱成形体を使用することも無意味ではないが、少なくとも後述するバタ材が当たる位置には邪魔になる。よって、バタ材が当たる位置の枡には、リブの高さ以下の断熱成形体を嵌め込んだ構成とすることが望まれる。 Rectangular ridges divided into a plurality of peripheral ribs (vertical ribs 1b, horizontal ribs 1c) and medium ribs (medium vertical ribs 1d, medium horizontal ribs 1e) installed on the back surface of the face plate 1a of the steel mold 1 described above 4 (or 4 ′, the same shall apply hereinafter) is a heat insulating concrete mold in which a heat insulating molded body 2 having a structure to be described later is fitted in one or two as a set, and the entire back surface of the face plate 1a is covered with a heat insulating material. A frame device 10 is configured. The size of the square ridge 4 is 15 cm × 15 cm in accordance with the above dimension example of the face plate 1 a, and the heat insulating molded body 2 is fitted into one ridge 4 at a ratio of one piece. On the other hand, two heat insulating molded bodies 2 and 2 having the same shape and the same size are fitted in a pair of arrangements in the rectangular ridge 4 ′ (15 cm × 30 cm). That is, the square heat insulating molded body 2 shown in FIG. 4a is commonly used for the square reed 4 and the rectangular reed 4 ′.
The illustrated heat insulating molded body 2 has a thermal conductivity measured by JIS A9511: 2006R of 0.02 to 0.06 W / (m · K), and a moisture permeability measured by ASTM E-96 of 0.03 to 0.10 g. A closed-cell foamed resin molding made of polyethylene or polypropylene, polystyrene and polyolefin composite resin, etc., which has a performance of / (m · hour) and hardly adheres to concrete or mortar, is shown in FIG. The back surface shape is used in a configuration in which a square having a length × width dimension of 150 × 150 mm and a thickness of about 25 mm is formed.
Incidentally, with respect to the thickness of the heat insulating molded body 2, it was confirmed that if it is at least 10 mm to 15 mm, the heat insulating heat retaining effect necessary for the face plate 1 a of the steel mold 1 is exhibited. Therefore, considering that the height of each rib is 55 mm as described above, when it is configured to have a thickness of about 25 mm, which is about half the height of the rib, curing in concrete casting with the steel mold 1 is performed. It is effective for. However, considering that the thickness of the heat insulating molded body 2 is 25 mm with respect to the height of the rib 55 mm, about 30 mm of the rib is exposed to the outside air, which causes heat input or heat dissipation. As long as economy permits, it is preferable to carry out by forming the thickness of the heat insulating molded body 2 at least equal to the height of the rib. For example, when the heat insulating molded body 2 having the above-described structure is fitted into the double-layered ridge 4 or 4 ′ formed by the ribs of the steel mold 1, it is convenient to cover with a heat insulating material just equal to the height of the ribs. is there. Although it is not meaningless to use a heat-insulating molded body having a thickness larger than the height of the rib, at least a position where a butter material described later hits is obstructive. Therefore, it is desirable to have a configuration in which a heat-insulating molded body having a height equal to or less than the height of the rib is fitted in the flange where the butter material hits.

図３と図４に示した断熱成形体２は、鋼製型枠１の面板１ａの背面に設置した周辺リブと中リブとで区画した矩形の枡４内へ嵌め込んで使用することを前提に形成されている。即ち、断熱成形体２は、その各側面が前記枡４を形成するリブにほぼぴったり内接して安定すること、即ち、運搬時や使用時に簡単に脱落しない程度に付着力を発揮する大きさの正方形（１５０×１５０ｍｍ）に形成され（図４ａ）、厚さはリブの高さ以下（２５ｍｍ）に構成されている。そして、背面（図４ａに現れた面）の外周辺と接する（又は臨む）部位には、四周辺それぞれのほぼ中央部位に１個ずつ合計４個の窪み２ａを備えている。
同窪み２ａの位置を更に特定すると、つぎのようになる。断熱成形体２の各窪み２ａは、図１に示した鋼製型枠１における面板１ａの背面に設置した周辺リブ（縦リブ１ｂ、横リブ１ｃ）と中リブ（中縦リブ１ｄ、中横リブ１ｅ）にそれぞれ設けられたフックボルト５の取付孔１ｆと対応する位置、および型枠相互間を接合するクリップ６の取付孔１ｇと対応する位置にそれぞれ、丁度窪み２ａの後述する開放側端部がぴったり整合する配置に設けられている。また、当該窪み２ａの深さｄおよび長さｅ（図４参照）もそれぞれ、図６に示したようにフックボルト５、Ｕクリップ６の取り付けに支障ない寸法に形成されている。
したがって、鋼製型枠１の前記周辺リブと中リブとで区画された枡４又は４’内に断熱成形体２が嵌め込まれても、フックボルト５を取付孔１ｆへ取り付ける作業、およびクリップ６を取付孔１ｇへ取り付ける作業には一切支障が生じない。 3 and 4 is assumed to be used by being fitted into a rectangular ridge 4 partitioned by a peripheral rib and a middle rib installed on the back surface of the face plate 1a of the steel mold 1. Is formed. That is, the heat-insulating molded body 2 is stable in that each side surface is inscribed in the ribs forming the ribs 4 so as to be stable, that is, it exhibits an adhesive force that does not easily fall off during transportation or use. It is formed in a square (150 × 150 mm) (FIG. 4 a), and the thickness is equal to or less than the height of the rib (25 mm). And the part which contact | connects (or faces) the outer periphery of a back surface (surface which appeared in FIG. 4a) is provided with the four depressions 2a in total, one each in the substantially central part of each of four periphery.
If the position of the recess 2a is further specified, it will be as follows. Recesses 2a of the heat-insulating molded body 2 have peripheral ribs (vertical ribs 1b, horizontal ribs 1c) and medium ribs (medium vertical ribs 1d, medium horizontal ribs) installed on the back surface of the face plate 1a in the steel mold 1 shown in FIG. The rib 2e) is provided with the opening side end of the recess 2a, which will be described later, at a position corresponding to the mounting hole 1f of the hook bolt 5 provided in the rib 1e) and a position corresponding to the mounting hole 1g of the clip 6 that joins between the molds. The parts are provided in an exactly aligned arrangement. Further, the depth d and the length e (see FIG. 4) of the recess 2a are also formed to dimensions that do not hinder the attachment of the hook bolt 5 and the U clip 6, as shown in FIG.
Therefore, even if the heat insulating molded body 2 is fitted in the flange 4 or 4 ′ defined by the peripheral rib and the middle rib of the steel mold 1, the operation of attaching the hook bolt 5 to the attachment hole 1 f and the clip 6. There is no hindrance to the work of attaching the to the mounting hole 1g.

上記したとおり、断熱成形体２の背面の形状（図４ａの形状）は、鋼製面板１ａの背面の周辺リブと中リブとで区画された正方形の枡４内にぴったり嵌め込まれる大きさ正方形に成形されている。そして、各窪み２ａは、前記正方形の四周辺それぞれのほぼ中央部位に、左右・上下方向に相対峙する配置に合計４個設けられている。しかも各窪み２ａは、断熱成形体２の外周辺側（側面）に向かって開放された形状に設けられている。
因みに、断熱成形体２の背面を示した図４ａに見られる窪み４の形状と大きさは、断熱成形体２の外周辺から内方への長さｅが約４０ｍｍ、開口部幅Ｕが３０ｍｍの矩形状で、深さは１２ｍｍに形成されている。
もっとも、上記したように背面の左右・上下方向に相対峙する配置に設けられた窪み２ａ、２ａの相互間で接近する関係（上記の寸法例で約６０ｍｍ程度の間隔）となる窪み内壁面２ａ’には、この断熱成形体２を枡４又は４’内へ嵌め込む作業、又は逆に枡４又は４’から断熱成形体２を抜き外す作業を容易にする手段として、相対峙する関係の窪み内壁面２ａ’、２ａ’同士を２本の指先で確実に容易に挟み持てるようにする手掛かり部が形成されている。
具体的には、図４ｂに示したとおり、断熱成形体２における前記窪み内壁面２ａ’は、窪み底面から外表面に向かって約８５度（又はそれ以下の角度）に傾けた傾斜面に形成されている。前記傾斜面の角度を約８５度（又はそれ以下の角度）に傾けると、相対峙して隣り合った二つの窪み２ａの窪み内壁面２ａ’、２ａ’同士を２本の指先で挟み持つ際に、指先が滑ることなく確実に掴めるからである。傾斜角度を９０度以上の窪み内壁面に形成すると、滑って挟み持つことが甚だ困難ないし不可能となるからである。
もっとも、手掛かり部としては、上記の傾斜面とする構成の限りではない。図４ｃに示したように、垂直壁の上端に水平方向の突き出し部を設けて手掛かり用凹部を形成して２本の指先で挟み持ちやすく滑り難い構成の引っ掛かり部２ａ”を形成した構成で実施することもできる。 As described above, the shape of the back surface of the heat-insulating molded body 2 (the shape of FIG. 4a) is a square having a size that fits perfectly in the square ridge 4 defined by the peripheral rib and the middle rib on the back surface of the steel face plate 1a. Molded. A total of four recesses 2a are provided in a substantially centered portion of each of the four periphery of the square so as to face each other in the horizontal and vertical directions. Moreover, each recess 2 a is provided in a shape that is open toward the outer peripheral side (side surface) of the heat insulating molded body 2.
Incidentally, the shape and size of the dent 4 shown in FIG. 4a showing the back surface of the heat-insulated molded body 2 are about 40 mm in length e from the outer periphery to the inside of the heat-insulated molded body 2 and 30 mm in the opening width U. The depth is 12 mm.
However, as described above, the inner wall surface 2a of the recess that is in a close relationship between the recesses 2a, 2a provided in the back-and-forth arrangement in the left-right and up-down directions (interval of about 60 mm in the above dimension example). 'Is a relationship that makes a relative heeling as a means for facilitating the work of fitting the heat insulating molded body 2 into the flange 4 or 4', or conversely removing the heat insulating molded body 2 from the flange 4 or 4 '. A clue portion is formed so that the inner wall surfaces 2a 'and 2a' of the dent can be reliably and easily held between two fingertips.
Specifically, as shown in FIG. 4 b, the inner wall surface 2 a ′ of the recess in the heat insulating molded body 2 is formed on an inclined surface inclined at about 85 degrees (or less) from the bottom surface of the recess toward the outer surface. Has been. When the angle of the inclined surface is tilted to about 85 degrees (or less), the inner wall surfaces 2a 'and 2a' of the two adjacent recesses 2a that are adjacent to each other are sandwiched between two fingertips. This is because the fingertip can be securely gripped without slipping. This is because, if the inclination angle is formed on the inner wall surface of the dent of 90 degrees or more, it is very difficult or impossible to slip and hold it.
However, the clue part is not limited to the above-described inclined surface. As shown in FIG. 4c, a horizontal protrusion is provided at the upper end of the vertical wall to form a clue recess, and a catch portion 2a "that is easy to hold between two fingertips and not slippery is formed. You can also

次に、図４に示した断熱成形体２の側面形状について更に説明する。図４ｂ〜ｄに示したように、鋼製型枠１の背面にリブで形成された枡４へ嵌め込む側面先端側の角部には、図示例の場合は約４５度方向に面取りした先細形状のテーパ部２ｃが形成されている。一方、反対の側面後端側（背面側）の角部には、図示例の場合、側面から厚さにして約１２ｍｍの範囲が、約３ｍｍ程度突き出した薄肉の縁出し２ｄが形成されている。この縁出し２ｄの段差部にも、嵌め込み方向の前方に向かって先細形状の面取りが行われている。
もっとも、上記した縁出し２ｄは、図４ｄで明らかなように、上記の窪み２ａが当該側面に向かって開放された端部分に関しては、同窪み２ａの開口幅が、上記したように約３０ｍｍであるのに加え、その左右両側に等しい余裕幅を確保した約４７ｍｍ程度の幅部分には縁出し２ｄを形成しないで、断熱成形体２の外周辺そのままの側面形状に形成されており、もって窪み２ａが当該側面に向かって開放された部分を縁出し成形することが複雑になること、および強度が低下する不都合を回避している。
上記構成の断熱成形体２は、上記側面先端側の角部に形成された先細形状のテーパ部２ｃを有するから、鋼製型枠１の背面に形成された枡４又は４’へ嵌め込む作業を容易に行える。そして、前記縁出し２ｄが存在することで、同縁出し２ｄの厚さと突き出し寸法の分だけ、枡４又は４’へ嵌め込んだ際の安定性、付着力（摩擦力）を高められる。また、枡４又は４’の大きさと断熱成形体２の外周辺寸法との関係に若干の不整合（寸法誤差など）があっても、断熱成形体２の嵌め込み設置の作業と結果にさして支障ない構成とされている。 Next, the side shape of the heat insulating molded body 2 shown in FIG. 4 will be further described. As shown in FIGS. 4b to 4d, in the case of the illustrated example, the tapered portion chamfered in the direction of about 45 degrees is provided at the corner portion on the front side of the side surface to be fitted into the flange 4 formed of ribs on the back surface of the steel mold 1. A tapered portion 2c having a shape is formed. On the other hand, in the corner portion on the opposite side rear end side (rear side), in the case of the illustrated example, a thin edge 2d protruding about 3 mm from the side surface in a thickness range of about 12 mm is formed. . The stepped portion of the edge 2d is also chamfered in a tapered shape toward the front in the fitting direction.
However, as is apparent from FIG. 4d, the edge 2d described above has an opening width of about 30 mm as described above with respect to the end portion where the recess 2a is opened toward the side surface. In addition, there is no edging 2d in the width portion of about 47 mm that secures the same margin width on both the left and right sides, and it is formed in the side shape of the outer periphery of the heat insulating molded body 2 as it is. It avoids the inconvenience of complicating and molding the portion where 2a is opened toward the side surface, and the strength is lowered.
Since the heat-insulated molded body 2 having the above-described configuration has a tapered taper portion 2c formed at the corner portion on the side surface front end side, it is fitted into the flange 4 or 4 'formed on the back surface of the steel mold 1 Can be easily performed. The presence of the edge 2d can increase the stability and adhesive force (frictional force) when fitted into the flange 4 or 4 'by the thickness and the protruding dimension of the edge 2d. Further, even if there is a slight mismatch (such as dimensional error) in the relationship between the size of the flange 4 or 4 'and the outer peripheral dimensions of the heat-insulated molded body 2, it interferes with the work and results of fitting and installing the heat-insulated molded body 2. There is no configuration.

以上に説明した図１記載の鋼製型枠１と、図３、図４に記載した断熱成形体２の構成を前提として、図２に示した断熱コンクリート型枠装置１０が次のように構成されている。
鋼製面板１ａの背面に同面板１ａの外周縁に沿って立つ鋼製の周辺リブ１ｂ、１ｃと、前記周辺リブで囲まれた枠内を仕切る鋼製の中リブ１ｄ、１ｅとで区画された、長手方向へ２列の各枡４及び４’内へ、上記構成の断熱成形体２が嵌め込まれている。ただし、図２の断熱コンクリート型枠装置１０の場合は、中縦リブ１ｄが中央部に１本だけ配置され、長手方向の端部寄り位置に中横リブ１ｅで区画された正方形の枡４（１５ｃｍ×１５ｃｍ）には、同形・同大に成形された上記の断熱成形体２が１個づつ嵌め込まれている。その他の長方形の枡４’（１５ｃｍ×３０ｃｍ）には、上記の断熱成形体２が２個を一組みとしてきっちり嵌め込まれている。 Assuming the construction of the steel mold 1 shown in FIG. 1 described above and the heat insulating molded body 2 shown in FIGS. 3 and 4, the heat insulating concrete form apparatus 10 shown in FIG. 2 is configured as follows. Has been.
The steel face plate 1a is partitioned by steel peripheral ribs 1b and 1c standing along the outer peripheral edge of the same face plate 1a, and steel medium ribs 1d and 1e that partition the frame surrounded by the peripheral ribs. In addition, the heat insulating molded body 2 having the above-described configuration is fitted into the two rows 4 and 4 ′ in the longitudinal direction. However, in the case of the heat insulating concrete formwork apparatus 10 of FIG. 2, only one middle vertical rib 1d is arranged at the center, and the square ridge 4 (partitioned by the middle horizontal rib 1e near the end in the longitudinal direction) 15 cm × 15 cm), each of the heat insulating molded bodies 2 formed in the same shape and size is fitted one by one. In the other rectangular ridge 4 ′ (15 cm × 30 cm), the above-mentioned heat-insulated molded body 2 is firmly fitted as a set.

一方、図５に示した断熱コンクリート型枠装置１０の場合は、周辺リブで囲まれた枠内を仕切る中縦リブ１ｄは幅方向に３本が等間隔に平行に配置され、中横リブ１ｅで区画された正方形の枡４と長方形の枡４’は、長手方向へ４列に形成されている。ただし、この実施例の場合も、面板１ａの縦寸は１５０ｃｍで図２の実施例と変わりなく、幅寸のみが６０ｃｍと大きい。よって正方形の枡４はやはり１５ｃｍ×１５ｃｍの大きさとされ、これには同形・同大に成形された上記の断熱成形体２が１個づつ嵌め込まれている。他の長方形の枡４’はいずれも１５ｃｍ×３０ｃｍの大きさに形成されており、これら長方形の枡４’には上記の断熱成形体２が２個を一組みとしてきっちり嵌め込まれている。
図５にはまた、当該断熱コンクリート型枠装置１０を、例えば図９に示したように、構築しようとするコンクリート構造物１１の形態に組み立てるに当たり使用するフックボルト５およびＵクリップ６の形状と取付状態も合わせて記載している。ただし、フックボルト５およびＵクリップ６を、鋼製型枠１の周辺リブ１ｂ、１ｃおよび中リブ１ｄ、１ｅに予め設けた取付孔１ｆおよび取付孔１ｇ（図１を参照）のうち、どの位置の孔を選択して取り付けるかは、型枠を組み立てる作業内容に応じて決定されるのであり、図示例の限りではない。 On the other hand, in the case of the heat insulating concrete formwork apparatus 10 shown in FIG. 5, three middle longitudinal ribs 1d for partitioning the inside of the frame surrounded by the peripheral ribs are arranged in parallel in the width direction, and the middle transverse rib 1e. The square ridges 4 and the rectangular ridges 4 ′ partitioned by are formed in four rows in the longitudinal direction. However, also in this embodiment, the vertical dimension of the face plate 1a is 150 cm, which is the same as the embodiment of FIG. 2, and only the width dimension is as large as 60 cm. Accordingly, the square ridge 4 is also 15 cm × 15 cm in size, and the above-described heat insulating molded bodies 2 formed in the same shape and size are fitted one by one. The other rectangular ridges 4 ′ are all formed in a size of 15 cm × 30 cm, and two of the heat insulating molded bodies 2 are fitted into the rectangular ridges 4 ′ as a set.
5 also shows the shape and attachment of hook bolts 5 and U-clips 6 used for assembling the heat insulating concrete formwork device 10 into the form of a concrete structure 11 to be constructed, for example, as shown in FIG. The state is also described. However, the hook bolt 5 and the U clip 6 can be placed at any position among the mounting holes 1f and 1g (see FIG. 1) provided in advance in the peripheral ribs 1b and 1c and the intermediate ribs 1d and 1e of the steel mold 1. Whether to select and attach the holes is determined according to the work contents for assembling the formwork, and is not limited to the illustrated example.

次に、上記のように構成した断熱コンクリート型枠装置１０を使用して、構築しようとするコンクリート構造物１１の形態に合わせてコンクリート打設用型枠を組み立てる方法について説明する。
上記したように、鋼製面板１ａの背面に、同面板１ａの外周縁に沿って立つ鋼製の周辺リブ１ｂ、１ｃと、前記周辺リブで囲まれた枠内を仕切る鋼製の中リブ１ｄ、１ｅとを備えた鋼製型枠１には、その背面の前記リブで区画された各枡４及び４’内へ、上記構成の断熱成形体２を嵌め込んで、先ずは断熱コンクリート型枠装置１０を完成する。もっとも、断熱コンクリート型枠装置１０の完成時期は、コンクリート打設工事の現場作業として完成することには限らない。断熱コンクリート型枠装置１０を製造する工場内で予め枡４および４’内へ断熱成形体２を嵌め込んで完成した断熱コンクリート型枠装置１０を現地へ搬入し、そのまま現地のコンクリート工事に使用する方法も実施できる。
上記の断熱コンクリート型枠装置１０を、構築しようとするコンクリート構造物１１の形態に合わせて組み立てる方法については、コンクリート構造物１１の形状、構造等に応じて多種多様であり、既往技術として公知、周知であるから、ここでいちいちケース分けして説明することは省き、本発明の断熱コンクリート型枠装置１０を使用する上での固有の事項を説明するに止める。
要するに、本発明の断熱コンクリート型枠装置１０も、構築しようとするコンクリート構造物１１の形態に合わせて組み立てるのであり、その組み立て方法の基本は、鋼製型枠１の周辺リブ１ｂ、１ｃおよび中リブ１ｄ、１ｅに予め用意された取付孔１ｆおよび取付用孔１ｇ（図１を参照）の中から、組み立てに適切な位置の取付孔１ｆおよび取付孔１ｇを選び出し、取付孔１ｆへフックボルト５を取り付け、また、取付孔１ｇへＵクリップ６を取り付けて断熱コンクリート型枠装置１０、１０相互間の接合を行う。こうしたフックボルト５の取り付け、およびＵクリップ６を取り付け作業の際に、各枡４および４’に嵌め込まれた断熱成形体２の存在が邪魔にならないことは、上述した通りである。 Next, a method for assembling a concrete casting form in accordance with the form of the concrete structure 11 to be constructed using the heat insulating concrete form apparatus 10 configured as described above will be described.
As described above, on the back surface of the steel face plate 1a, the steel peripheral ribs 1b and 1c standing along the outer peripheral edge of the same face plate 1a, and the steel medium rib 1d for partitioning the inside of the frame surrounded by the peripheral ribs. In the steel mold 1 provided with 1e, the heat insulating molded body 2 having the above-described configuration is fitted into the ribs 4 and 4 'defined by the ribs on the back surface thereof. The apparatus 10 is completed. But the completion time of the heat insulation concrete formwork apparatus 10 is not necessarily completed as an on-site work of concrete placement work. In the factory where the heat insulating concrete formwork apparatus 10 is manufactured, the heat insulating concrete formwork apparatus 10 which has been completed by previously fitting the heat insulating molded body 2 into the coffins 4 and 4 'is carried to the site and used as it is for local concrete work. A method can also be implemented.
About the method of assembling said heat insulation concrete formwork apparatus 10 according to the form of the concrete structure 11 which it is going to construct, it is various according to the shape, structure, etc. of the concrete structure 11, and is known as a past technique. Since it is well-known, it will not be described separately for each case here, but only the specific matters in using the heat insulating concrete formwork apparatus 10 of the present invention will be described.
In short, the heat insulating concrete formwork apparatus 10 of the present invention is also assembled according to the form of the concrete structure 11 to be constructed, and the basis of the assembling method is the peripheral ribs 1b, 1c of the steel formwork 1 and From the mounting holes 1f and mounting holes 1g (see FIG. 1) prepared in advance for the ribs 1d and 1e, the mounting holes 1f and mounting holes 1g at positions suitable for assembly are selected, and the hook bolts 5 are connected to the mounting holes 1f. In addition, the U-clip 6 is attached to the attachment hole 1g, and the heat insulating concrete mold apparatuses 10 and 10 are joined to each other. As described above, when the hook bolt 5 is attached and the U clip 6 is attached, the presence of the heat insulating molded body 2 fitted in the flanges 4 and 4 'does not get in the way.

因みに図６は、断熱コンクリート型枠装置１０へフックボルト５を取り付け、Ｕクリップ６を取り付けた組み立て途中の実施例を示している。フックボルト５を取付孔１ｆへ取り付け、或いはＵクリップ６を取付孔１ｇへ取り付ける場合には、断熱成形体２の窪み２ａが丁度、フックボルト５の取付孔への挿入、およびＵクリップ６を取付孔へ挿入することを誘導する空所を提供する位置と深さに形成されているのである。
図７の実施例は、断熱コンクリート型枠装置１０、１０相互の接合を、取付孔１ｇを利用して、ボルト８とナット８ａとによる締結を行った実施例を示している。ボルト８とナット８ａとによる締結作業を容易にするため、該当する枡４又は４’へ断熱成形体２を嵌め込む作業は後回しとし、ボルト８とナット８ａとによる締結作業を先行して行う。その後に断熱成形体２は裏返し状態に嵌め込んだ構成を示している。かくすると、窪み２ａが下向きになって、丁度ボルト８とナット８ａを避ける空所を形成することになって好都合である。
もっとも、図８に示す実施例のように、ボルト８とナット８ａの締結後に行う断熱成形体２の嵌め込みを、断熱成形体２を正規の向きに行うこともできる。この場合、ボルト８およびナット８ａの存在により、断熱成形体２の嵌め込み状態は若干妨げられ、断熱成形体２の一部は屈曲される。しかし、面板１ａの全面を断熱材で覆うという目的はほぼ達成されている構成を理解できるであろう。 FIG. 6 shows an embodiment in the middle of assembly in which the hook bolt 5 is attached to the heat insulating concrete formwork apparatus 10 and the U clip 6 is attached. When the hook bolt 5 is attached to the attachment hole 1f or the U clip 6 is attached to the attachment hole 1g, the recess 2a of the heat insulating molded body 2 is just inserted into the attachment hole of the hook bolt 5 and the U clip 6 is attached. It is formed at a position and depth that provides a void to guide insertion into the hole.
The embodiment of FIG. 7 shows an embodiment in which the heat insulating concrete mold apparatuses 10 and 10 are joined to each other by using bolts 8 and nuts 8a using the mounting holes 1g. In order to facilitate the fastening operation with the bolt 8 and the nut 8a, the operation of fitting the heat insulating molded body 2 into the corresponding flange 4 or 4 'is postponed, and the fastening operation with the bolt 8 and the nut 8a is performed in advance. After that, the heat insulating molded body 2 shows a configuration in which it is fitted in an inverted state. In this way, it is convenient that the recess 2a is directed downward to form a space that just avoids the bolt 8 and the nut 8a.
However, as in the embodiment shown in FIG. 8, the heat insulating molded body 2 can be fitted in a normal orientation after the bolt 8 and the nut 8 a are fastened. In this case, due to the presence of the bolt 8 and the nut 8a, the fitted state of the heat insulating molded body 2 is somewhat hindered, and a part of the heat insulating molded body 2 is bent. However, it will be understood that the objective of covering the entire surface of the face plate 1a with a heat insulating material is almost achieved.

上記のように取り付けたフックボルト５を、図９に例示したように、バタ材７と結合することにより、複数の断熱コンクリート型枠装置１０…を、構築するべきコンクリート構造物１１の形態に合わせて並べて一連の構成に組み立て、コンクリート打設に備えることができる。
こうして組み立てたコンクリート型枠の内側へコンクリートの打設を行うと、断熱作用により適切な養生で材令を重ねることができる。
即ち、断熱コンクリート型枠装置１０の面板１ａの背面側へ取り付けた断熱成形体２の断熱作用により、打設コンクリートの断熱（保温）養生を良好に行うことができる。こうした養生により打設コンクリートが所望の強度に硬化（強度を発現）した後には、断熱コンクリート型枠装置１０の脱型と解体を行うことは周知の手順である。その際、本発明の断熱コンクリート型枠装置１０の場合は、前記脱型および解体後に、その後の保管の目的に応じて、例えば鋼製型枠１の各枡から断熱成形体２を全て抜き外して回収することを自在に行うことができる。 As illustrated in FIG. 9, the hook bolts 5 attached as described above are combined with the butter material 7 so that the plurality of heat insulating concrete formwork devices 10... Match the form of the concrete structure 11 to be constructed. They can be assembled side-by-side and assembled into a series of structures to prepare for concrete placement.
When concrete is placed inside the concrete form thus assembled, it is possible to stack the ages with an appropriate curing due to the heat insulating action.
That is, the heat insulation (heat retention) curing of the cast concrete can be performed well by the heat insulating action of the heat insulating molded body 2 attached to the back side of the face plate 1a of the heat insulating concrete formwork apparatus 10. It is a well-known procedure to perform demolding and dismantling of the heat insulating concrete formwork device 10 after the cast concrete has been cured to a desired strength (expressing strength) by such curing. At that time, in the case of the heat insulating concrete form apparatus 10 of the present invention, after the demolding and dismantling, for example, all of the heat insulating formed body 2 is removed from each cage of the steel formwork 1 in accordance with the purpose of subsequent storage. Can be freely collected.

以上に本発明を図示した実施例に基づいて説明したが、本発明は、上記実施例の構成に限定されない。本発明の目的と要旨を逸脱しない範囲において、当業者が必要に応じて通常行う設計変更や応用の範囲を含むことを念のため言及する。 Although the present invention has been described based on the illustrated embodiment, the present invention is not limited to the configuration of the above embodiment. It should be noted that the present invention includes a range of design changes and applications that are usually made by those skilled in the art without departing from the scope and spirit of the present invention.
