Description

本発明は、型枠パネルを構成する断熱材（パネル）として多種の外装材や断熱材を適用することができ、しかも断熱材の内側にてコンクリートを打設する空間に配設する間隔保持部材（セパレータ）と連結する構成であるため、型枠パネルを適正位置に保持される打設を可能とし、ノロの漏れ出しをも防止でき、足場やバタ材等を不要又は最小限とできる型枠パネル用支持材、及びコンクリート壁体の構築構造に関する。   In the present invention, various exterior materials and heat insulating materials can be applied as the heat insulating material (panel) constituting the formwork panel, and the interval holding member is disposed in the space where the concrete is placed inside the heat insulating material. Because it is configured to be connected to the (separator), it is possible to place the formwork panel in an appropriate position, prevent leakage of the gutter, and eliminate or minimize the use of scaffolding and butter material. The present invention relates to a panel support material and a construction structure of a concrete wall.

従来、コンクリート構造物を構築するにあたり、外装材や下地材（断熱材）を型枠として用いる兼用型枠が提案され、その多くは、以下に示す特許文献１〜４のように断熱材を型枠として用いる方法、構造等が開示されている。   Conventionally, in the construction of concrete structures, dual-purpose molds using exterior materials and base materials (heat insulating materials) as molds have been proposed, and many of them are made of a heat insulating material as described in Patent Documents 1 to 4 below. Methods, structures, etc. used as frames are disclosed.

特許文献１には、断熱材６に複合補強材７を一体化した構成の兼用断熱材パネルＡを用いてコンクリートを打設する方法が開示されている。
しかし、この特許文献１では、型枠締め付け用金具３・セパレータ５等が断熱材６、補強材７を貫通し、補強材７の表面（外側）まで突出しているため、貫通孔からノロ（セメント水）が漏れるという問題があった。また、このノロは、強アルカリであって補強材７の外面を汚損するため、硬化後にノロを拭き取ったり、補強材７の外面を仕上げ材（内装ボード１１）で覆う必要があった。さらに、補強材７で兼用型枠を押さえるため、作業を兼用断熱材パネルＡの外側から行う必要があり、足場を組むスペースが必要となり、狭小地（隣家との間に十分なスペースが無い等）での構築は難しかった。また、硬化後の化粧仕上げも、狭小地の場合、作業が困難になるという問題もあった。 Patent Document 1 discloses a method of placing concrete using a combined heat insulating material panel A having a structure in which a composite reinforcing material 7 is integrated with a heat insulating material 6.
However, in this patent document 1, since the mold fastening metal fitting 3 and the separator 5 penetrate the heat insulating material 6 and the reinforcing material 7 and protrude to the surface (outside) of the reinforcing material 7, noro (cement) There was a problem that water) leaked. Moreover, since this noro is a strong alkali and soils the outer surface of the reinforcing material 7, it is necessary to wipe off the noro after curing or to cover the outer surface of the reinforcing material 7 with a finishing material (interior board 11). In addition, since the dual-purpose formwork is held down by the reinforcing material 7, it is necessary to perform the work from the outside of the dual-purpose heat insulating panel A, and a space for assembling a scaffold is required. ) Was difficult to build. In addition, the decorative finish after curing has a problem that the work becomes difficult in the case of a narrow area.

また、特許文献２は、断熱材２に、仕上げ材となるタイル３が一体化されたセメント系硬質材４を接合した建築物外断熱壁が開示されている。
しかし、この特許文献２では、図示されるように、アンカー部材５のボルトやナット、セパレータの端部などが仕上げ材３の表面に表れるため、意匠的に好ましくなかった。それを解消するためには、前記特許文献１と同様の処理が必要であった。 Patent Document 2 discloses a heat insulating wall outside a building in which a cement-based hard material 4 in which a tile 3 as a finishing material is integrated with a heat insulating material 2 is joined.
However, in this patent document 2, since the bolt of a anchor member 5, a nut, the edge part of a separator, etc. appear on the surface of the finishing material 3 as shown in figure, it was not preferable in design. In order to solve this problem, the same processing as in Patent Document 1 is necessary.

また、特許文献３には、隣り合う発泡プラスチック製の断熱性板材１，１の側縁を、略Ｈ型に形成したジョイント部材２にて連結した型枠兼用断熱性板材が開示されている。
しかし、この特許文献３では、その図３に図示されるようにジョイント部材２が存在しない位置にセパレータを配置させているため、コンクリートを打設する際の打設圧力によっては断熱性板材１を変形又は破断させる虞があった。また、同図に示されるように断熱性板材の外側には「内端太」及び「外端太」が配され、上記と同様に足場等の設置が必要となるものであった。 Patent Document 3 discloses a heat-insulating plate material that also serves as a formwork in which side edges of adjacent heat-insulating plate materials 1 and 1 made of foamed plastic are connected by a joint member 2 formed in a substantially H shape.
However, in this patent document 3, since the separator is arrange | positioned in the position where the joint member 2 does not exist as shown in the figure in FIG. 3, depending on the placement pressure at the time of placing concrete, the heat insulating board | plate material 1 is used. There was a risk of deformation or breakage. Further, as shown in the figure, “inner end thick” and “outer end thick” are arranged on the outside of the heat insulating plate material, and it is necessary to install a scaffold or the like in the same manner as described above.

さらに、特許文献４には、隣り合う発泡プラスチック板２１の側縁を、略Ｈ型に形成した連結具２２に嵌め込んで外側の型枠とする構造が記載されている。
しかし、この特許文献４では、連結具２２の内側に形成した縦縁２２２に、帯板状に形成したセパレータ４の先端を引っ掛けるように係止する点で前記特許文献３よりはコンクリートの打設応力に抗しているものの、引っ掛け部が外れ易いこと、特定のセパレータを用いること、特定のパネルを内枠として用いること等多くの制限があり、実用性に問題があった。 Furthermore, Patent Document 4 describes a structure in which side edges of adjacent foamed plastic plates 21 are fitted into a connector 22 formed in a substantially H shape to form an outer mold.
However, in Patent Document 4, concrete is placed more than in Patent Document 3 in that the vertical edge 222 formed on the inner side of the connector 22 is locked so as to hook the tip of the separator 4 formed in a strip shape. Although it resists stress, there are many limitations such as the ease of detaching the hook, the use of a specific separator, the use of a specific panel as an inner frame, and there was a problem in practicality.

特公平７−６２４４号公報Japanese Patent Publication No. 7-6244 特開平１１−３１５６０１号公報JP 11-315601 A 特開２００６−３３６２８４号公報JP 2006-336284 A 特開２００８−１８４７５８号公報JP 2008-184758 A 特開２０１３−１３３６５６号公報JP2013-133656A

前述のように、前記特許文献１〜４に記載の方法又は構造では、コンクリートの打設に際し、ノロの漏れや断熱材の変形等の問題を生ずるものであり、更には使用する材料に関して特定の材料を用いるという制限を有するものであった。このようにノロの漏れや断熱材の変形が生ずると、型枠の構築に際し、足場の設置、補強材（バタ材）の配設に費用や時間が掛かるものであった。   As described above, the methods or structures described in Patent Documents 1 to 4 cause problems such as leakage of the metal and deformation of the heat insulating material when placing concrete, and further, specific methods regarding the material to be used are specified. There was a limitation of using materials. Thus, when leakage or deformation of the heat insulating material occurs, it takes cost and time to install the scaffolding and dispose the reinforcing material (batter material) when constructing the mold.

そのため、本出願人は、上記問題点に鑑み、特にノロの漏れ出しを防止できる型枠パネルとして特許文献５に記載の構造を提案した。
しかし、この特許文献５では、断熱材の外側に特殊形状の外装材を積層してなる構成であって、ノロの漏れ出しに関しては極めて高い性能を有しているものの、このような外装材を用いることは汎用性の点では改良の余地があった。 Therefore, in view of the above-mentioned problems, the present applicant has proposed the structure described in Patent Document 5 as a formwork panel that can prevent the leakage of noro.
However, in this patent document 5, although it is the structure formed by laminating | stacking a special-shaped exterior material on the outer side of a heat insulating material, and although it has extremely high performance regarding leaking out, such an exterior material is used. The use has room for improvement in terms of versatility.

そこで、本発明は、型枠パネルを構成する断熱材（パネル）として多種の外装材や断熱材を適用することができ、しかも断熱材の内側にてコンクリートを打設する空間に配設する間隔保持部材（セパレータ）と連結する構成であるため、型枠パネルを適正位置に保持される打設を可能とし、ノロの漏れ出しをも防止でき、足場やバタ材等を不要又は最小限とできる型枠パネル用支持材、及びコンクリート壁体の構築構造を提案することを目的とする。   Therefore, the present invention can apply various exterior materials and heat insulating materials as the heat insulating materials (panels) constituting the formwork panel, and is disposed in the space where the concrete is placed inside the heat insulating materials. Since it is configured to be connected to the holding member (separator), it is possible to place the formwork panel in an appropriate position, to prevent leakage of the slot, and to eliminate or minimize the scaffolding and butter material. The purpose is to propose a supporting structure for formwork panels and a construction structure of concrete wall.

本発明は、上記に鑑み提案されたものであり、一定間隔を保持して配置される型枠間にコンクリートを打設する工法において、少なくとも一方の型枠として用いられる型枠パネル用支持材であって、外側フランジと内側フランジと両フランジを繋ぐウエブからなり、両フランジ間に型枠パネルの端縁を保持することができ、内側フランジの更に内側には前記型枠間に配される間隔保持部材の先端を連結する締着部を有することを特徴とする型枠パネル用支持材に関するものである。 The present invention has been proposed in view of the above, and is a support for a formwork panel that is used as at least one formwork in a construction method in which concrete is placed between formwork that is arranged at a constant interval. there are made from the web connecting the outer flange and the inner flange and the flanges, the edges of the formwork panel between two flanges can hold, further spacing inwardly disposed between the mold inner flange The present invention relates to a support for a formwork panel, characterized by having a fastening portion for connecting the leading ends of the holding members.

さらに、本発明は、前記支持材を用いた型枠パネルをコンクリート打設空間の少なくとも一方の型枠として用いたことを特徴とするコンクリート壁体の構築構造をも提案するものである。   Furthermore, the present invention also proposes a construction structure for a concrete wall characterized in that a formwork panel using the support material is used as at least one formwork of a concrete placement space.

また、本発明は、前記コンクリート壁体の構築構造において、内側フランジと型枠パネルを固定ビスにて固定したことを特徴とするコンクリート壁体の構築構造をも提案する。 The present invention also proposes a concrete wall construction structure characterized in that the inner flange and the formwork panel are fixed with fixing screws in the concrete wall construction structure.

また、本発明は、前記コンクリート壁体の構築構造において、前記締着部がコンクリート打設空間内に位置することを特徴とするコンクリート壁体の構築構造をも提案する。 Further, the present invention is the in the construction structure of the concrete wall, the fastening portion is proposed to build the structure of the concrete wall, characterized in that located in the between concrete設空.

本発明の型枠パネル用支持材は、外側フランジと内側フランジとの間に型枠パネルの端縁を保持することができるため、型枠パネルとして多種の外装材や断熱材を適用することができる。
また、型枠パネルの内側にてコンクリートを打設する空間に配設する間隔保持部材（セパレータ）と連結する構成であるため、型枠パネルが適正位置に保持される打設を可能とするものであり、ノロの漏れ出しをも防止できる。そのため、本発明では、足場、バタ材等を不要（or最小限）とすることができ、全体的な工事コストを抑制することができるものである。 Since the support for a formwork panel of the present invention can hold the edge of the formwork panel between the outer flange and the inner flange, various exterior materials and heat insulating materials can be applied as the formwork panel. it can.
In addition, because it is configured to be connected to a spacing member (separator) disposed in the space for placing concrete inside the formwork panel, it can be placed so that the formwork panel is held in an appropriate position. It is possible to prevent leaking out. Therefore, in the present invention, scaffolds, butter materials, etc. can be made unnecessary (or minimum), and the overall construction cost can be suppressed.

また、本発明の前記支持材を用いた型枠パネルをコンクリート打設空間の少なくとも一方の型枠として用いたコンクリート壁体の構築構造は、型枠パネルが適正位置に保持されるものであるため、適正厚みのコンクリート打設を実施できる。   Moreover, the construction structure of the concrete wall body using the formwork panel using the support material of the present invention as at least one formwork of the concrete placement space is such that the formwork panel is held at an appropriate position. It is possible to place concrete with an appropriate thickness.

また、内側フランジと型枠パネルを固定ビスにて固定した場合には、型枠パネルはその端縁がフランジ間に保持されているので、二重の保持作用が果たされるものとなる。 In addition, when the inner flange and the formwork panel are fixed with a fixing screw, the edge of the formwork panel is held between the flanges, so that a double holding action is achieved.

また、前記締着部がコンクリート打設空間内に位置する場合には、コンクリート打設時に前記締着部にコンクリートが流入硬化するため、間隔保持部材とコンクリートと支持材がより強固に一体化される。 Further, when the fastening portion is located in between the concrete設空, because the concrete is hardened flows into the fastening portion to the concrete after casting, the spacing members and the concrete and the support material is more firmly integrated The

本発明の型枠パネル用支持材は、一定間隔を保持して配置される型枠間にコンクリートを打設する工法において、少なくとも一方の型枠として用いられる。
この型枠パネル用支持材（以下、単に支持材という）は、外側フランジと内側フランジと両フランジを繋ぐウエブからなり、両フランジ間に型枠パネルの端縁を保持することができ、内側フランジの内側には前記型枠間に配される間隔保持部材を連結する締着部を有する。 The support for a formwork panel of the present invention is used as at least one formwork in a construction method in which concrete is placed between formwork arranged at a constant interval.
This formwork panel support material (hereinafter simply referred to as support material) consists of a web connecting the outer flange, the inner flange and both flanges, and can hold the edge of the formwork panel between the two flanges. On the inside, there is a fastening portion for connecting a spacing member disposed between the molds.

前記外側フランジは、型枠パネルの表面側に配置され、前記内側フランジは、型枠パネルの裏面側（コンクリート側）に配置され、前記ウエブは、左右に隣接する型枠パネルの側端面の間に配置されるものである。
この支持材は、後述する図示実施例に示すように両フランジが略水平状に延在し、ウエブはそれらに対して略垂直状に交わる構成であるため、物理的に曲げ強度が高い構造特性を有している。なお、フランジ間の溝幅、即ちウエブの長さが、型枠パネルの厚みに相当するが、コンクリート打設厚等の建築物を勘案して決定すればよい。
この支持材としては、素材や成形法を限定するものではなく、各種の材料を適用することができ、金属製でも硬質樹脂製でもよいし、アルミ等の押出型材を用いてもよい。 The outer flange is disposed on the front side of the formwork panel, the inner flange is disposed on the back side (concrete side) of the formwork panel, and the web is between the side end surfaces of the left and right formwork panels. Is to be arranged.
As shown in the illustrated embodiment described later, this support material has a structure in which both flanges extend in a substantially horizontal shape and the web intersects with each other in a substantially vertical shape, so that the structural properties are physically high in bending strength. have. In addition, although the groove width between flanges, ie, the length of the web, corresponds to the thickness of the formwork panel, it may be determined in consideration of a building such as a concrete casting thickness.
The support material is not limited to a material or a molding method, and various materials can be applied. The support material may be made of metal or hard resin, or an extrusion mold material such as aluminum may be used.

前記締着部は、対向する型枠と連結するための間隔保持部材の端縁を連結するものであればよく、例えば後述する図示実施例のように裏面側へ突出状（ボックス状）としてもよい。即ち後述する図示実施例では、内側フランジとユ字状とするボックス状の締着部を形成したが、コンクリート打設時にこのボックス内にコンクリートが流入硬化するため、間隔保持部材とコンクリートと支持材がより強固に一体化される。
また、連結するための構成としては螺着（螺合）が望ましいが、特にこれに限定するものではない。後述する図示実施例では間隔保持部材の端縁に締着可能な雌ねじを有する六角ナット、四角ナットなどの角ナットを配置したが、突出部分を雌ねじ加工するものであってもよい。 The fastening portion only needs to connect the edge of the spacing member for connecting to the opposing mold, and for example, as shown in the illustrated embodiment to be described later, the fastening portion may have a protruding shape (box shape). Good. That is, in the illustrated embodiment described later, a box-shaped fastening portion having an inner flange and a U-shape is formed. However, since concrete flows into the box and hardens when the concrete is placed, the spacing member, the concrete, and the support material are used. Are more firmly integrated.
Moreover, as a structure for connection, screwing (screwing) is desirable, but it is not particularly limited to this. In the illustrated embodiment to be described later, a square nut such as a hexagonal nut or a square nut having a female screw that can be fastened to the end edge of the spacing member is disposed. However, the protruding portion may be processed with a female screw.

前記締着部で連結する間隔保持部材は、コンクリート型枠工法において、コンクリート打設空間の間隔を保持するセパレータと称される部材であり、言い換えれば施工するコンクリート壁の厚みを確保ずるための保持部材である。
この間隔保持部材としては、その一端が本発明の支持材（締着部にて）に締着するものであれば、単体であっても複数部材を連結したものであってもよい。複数部材で構成する場合、支持材（締着部）と連結する部材以外は、セパレータ、プラスチックコーン（Ｐコン）、筒状部材等の汎用品を使用することが可能である。例えば支持材と連結する棒状部材の長さ範囲全てを筒状部材で包囲されている構成でもよいし、後述する図示実施例のように分離可能な複数部材で形成され、螺合手段で接続され、一方側に配された一部のみが筒状部材で包囲されている構成でもよい。また、コンクリート打設厚に対して異なる長さのものを用意してもよいし、支持材に連結する間隔保持部材を統一し、汎用品であるセパレータや筒状部材等の長さを変えることで様々な打設厚に対応するものであってもよい。 The interval holding member connected by the fastening portion is a member called a separator that holds the interval of the concrete placement space in the concrete formwork method, in other words, holding for ensuring the thickness of the concrete wall to be constructed. It is a member.
The spacing member may be a single member or a plurality of members connected as long as one end thereof is fastened to the support material (at the fastening portion) of the present invention. When constituted by a plurality of members, it is possible to use general-purpose products such as a separator, a plastic cone (P-con), and a cylindrical member other than the member connected to the support material (fastening portion). For example, the entire length range of the rod-shaped member connected to the support member may be surrounded by a cylindrical member, or it may be formed of a plurality of separable members as shown in the illustrated embodiment described below and connected by screwing means. In addition, a configuration in which only a part disposed on one side is surrounded by a cylindrical member may be employed. Also, different lengths may be prepared for the concrete casting thickness, the spacing members connected to the support material are unified, and the lengths of general-purpose products such as separators and cylindrical members are changed. It may correspond to various placement thicknesses.

本発明の支持材の両フランジ間に保持される型枠パネルとしては、コンクリート打設時に変形しないものであればよく、その材質、板厚等は特に限定するものではなく、単層板でも複層（積層）板でもよい。例えば後述する図示実施例では、フレキ板、ケイカル板等の繊維強化セメント板と発泡材（断熱材）による積層板を用いているが、難燃性、不燃性等の機能性ボード材を用いてもよい。この型枠パネルの厚みについては、前記フランジ間の溝幅にても説明したようにコンクリート打設厚等の建築物を勘案して決定すればよい。なお、厚み方向に弾性を有する断熱材を用いて積層状とした場合には、厚み方向に圧縮する等の厚み調整を行うことができる。   The form panel held between both flanges of the support material of the present invention is not particularly limited as long as it does not deform when casting concrete, and the material, thickness, etc. are not particularly limited. A layer (laminated) plate may be used. For example, in the illustrated embodiment to be described later, a laminated board made of a fiber reinforced cement board such as a flexible board or a calcium board and a foamed material (heat insulating material) is used, but a functional board material such as flame retardancy or non-flammability is used. Also good. The thickness of the formwork panel may be determined in consideration of a building such as a concrete casting thickness as described for the groove width between the flanges. In addition, when it is set as the laminated form using the heat insulating material which has elasticity in the thickness direction, thickness adjustment, such as compressing in the thickness direction, can be performed.

前記積層状の型枠パネルを用いる場合には、複数種類が予め一体化されたものであっても、個別の板を積層状としたものでもよい。
また、積層状の型枠パネルを用いる場合には、後述する図示実施例のように表面側或いは裏面側（コンクリート側）の少なくとも一方に高強度（曲げ荷重）の層（例えば前述の繊維強化セメント板等）を設けることが好ましい。
さらに、最表面側に配設する断熱材としては、仕上げ材を兼用するものでも、別途仕上げ処理（仕上げ材の貼付、仕上げ塗装等）を施したものでもよい。 When the laminated form panel is used, a plurality of types may be integrated in advance, or individual plates may be laminated.
When a laminated formwork panel is used, a high-strength (bending load) layer (for example, the above-mentioned fiber reinforced cement is provided on at least one of the front surface side or the back surface side (concrete side) as in the illustrated embodiment described later. It is preferable to provide a plate or the like.
Further, the heat insulating material disposed on the outermost surface side may be a material that also serves as a finishing material, or a material that has been separately subjected to a finishing treatment (finishing material sticking, finishing coating, etc.).

また、積層状の型枠パネルに限らず、前記支持材の内側フランジと型枠パネルを固定ビスにて固定するようにしてもよく、この場合には、型枠パネルはその端縁がフランジ間に保持されているので、二重の保持作用が果たされるものとなる。 In addition to the laminated formwork panel, the inner flange of the support material and the formwork panel may be fixed with fixing screws. In this case, the edge of the formwork panel is between the flanges. Thus, a double holding action is achieved.

また、前述のように本発明の支持材は、少なくとも一方の型枠として用いられるものであって、両方の型枠に用いられるものでもよい。
したがって、本発明の前記支持材を用いたコンクリート壁体の構築構造は、一方のみの型枠として前記構成の支持材を用いる場合と、両方の型枠として前記構成の支持材を用いる場合とがある。 Further, as described above, the support material of the present invention is used as at least one mold, and may be used in both molds.
Therefore, the construction structure of the concrete wall body using the support material of the present invention includes a case where the support material having the above configuration is used as only one formwork and a case where the support material having the above structure is used as both formwork. is there.

本発明の支持材１は、一定間隔を保持して配置される型枠Ａ，Ｂ間にコンクリートＣを打設する工法において、少なくとも一方の型枠として用いられるが、図１に示す第１実施例では一方の型枠Ａとして用いられる。
この支持材１は、図１及び図２，図３（ａ）〜（ｄ）に示す第１実施例のように外側フランジ１１と内側フランジ１２と両フランジ１１，１２を繋ぐウエブ１３からなり、両フランジ１２，１３間に型枠パネル２の端縁を保持することができ、内側フランジ１２の内側には前記型枠Ａ，Ｂ間に配される間隔保持部材３を連結する締着部１４を有する構成である。 The support material 1 of the present invention is used as at least one formwork in a construction method in which concrete C is placed between the formwork A and B that are arranged at a constant interval. The first embodiment shown in FIG. In the example, it is used as one mold A.
This support material 1 consists of a web 13 connecting the outer flange 11, the inner flange 12, and both flanges 11, 12 as in the first embodiment shown in FIGS. An end edge of the formwork panel 2 can be held between the flanges 12 and 13, and a fastening portion 14 for connecting a spacing member 3 disposed between the formwork A and B inside the inner flange 12. It is the structure which has.

前記外側フランジ１１は、型枠パネル２の表面側に配置され、前記内側フランジ１２は、型枠パネル２の裏面側（コンクリートＣ側）に配置され、前記ウエブ１３は、左右に隣接する型枠パネル２，２の側端面の間に配置されるものである。   The outer flange 11 is disposed on the front side of the mold panel 2, the inner flange 12 is disposed on the back side (concrete C side) of the mold panel 2, and the web 13 is adjacent to the left and right mold frames. It is arranged between the side end surfaces of the panels 2 and 2.

この第１実施例では、両フランジ１１，１２が略水平状に延在し、ウエブ１３はそれらに対して略垂直状に交わるため、物理的に曲げ強度が高い構造特性を有している。また、ウエブ１３の裏面側へ略Ｌ字状に突出するＬ字状片１５（締着部１４）を形成したので、支持材１全体の形状は断面略モ字状に形成されている。
また、この第１実施例における支持材１の外側フランジ１１は、中央が肉厚の短幅の横片状に形成され、それ以外（内側フランジ１２、ウエブ１３、Ｌ字状片１５）はほぼ同一板厚に形成されている。内側フランジ１２は、左右方向に長く延在し、締着具である固定ビス６を打ち込むための孔１２１が設けられている。また、ウエブ１３は、縦片状に形成され、その長さは、両フランジ１１，１２間の溝幅、即ち保持する型枠パネル２の全厚みに相当するが、コンクリート打設厚等の建築物を勘案して決定すればよい。さらに、Ｌ字状片１５には、間隔保持部材３を取り付けるための通孔１５１が形成されている。 In the first embodiment, both flanges 11 and 12 extend in a substantially horizontal shape, and the web 13 intersects in a substantially vertical shape with respect to them, so that it has a structural characteristic that physically has a high bending strength. Moreover, since the L-shaped piece 15 (fastening part 14) which protrudes in a substantially L shape on the back surface side of the web 13 is formed, the overall shape of the support material 1 is formed in a substantially square-shaped cross section.
Further, the outer flange 11 of the support member 1 in the first embodiment is formed in the shape of a short horizontal strip with the center being thick, and the other portions (the inner flange 12, the web 13, the L-shaped piece 15) are substantially the same. The same thickness is formed. The inner flange 12 extends long in the left-right direction, and is provided with a hole 121 for driving a fixing screw 6 as a fastener . The web 13 is formed in the shape of a vertical piece, the length of which corresponds to the groove width between the flanges 11 and 12, that is, the total thickness of the formwork panel 2 to be held. You should decide in consideration of things. Further, the L-shaped piece 15 is formed with a through-hole 151 for attaching the spacing member 3.

前記締着部１４は、対向する型枠Ａ，Ｂと連結するための間隔保持部材３の端縁を連結するものであり、裏面側へ略Ｌ字状に突出するボックス状とし、内側フランジとユ字状としたが、コンクリート打設時にこのボックス内にコンクリートＣが流入硬化するため、コンクリートＣと支持材１が一体化される。   The fastening portion 14 connects the end edges of the spacing member 3 for connecting to the opposing molds A and B, and is formed in a box shape protruding substantially L-shaped to the back side, Although it has a U-shape, the concrete C and the support material 1 are integrated because the concrete C flows into the box and hardens when the concrete is placed.

この第１実施例における前記間隔保持部材３は、型枠間の距離、即ち打設しようとするコンクリート厚みに応じて適宜選択されるものであり、図１（ｃ）に示すようにコンクリート打設空間内に位置する第１棒状部材３Ａの端縁（図面では左端）に形成した雄ネジ３１を前記締着部１４に配置した構成である。この棒状部材３Ａは、ナット７が締着される雄ネジ３１から拡太部分３２を介して太径部分３３が形成され、他端（図面では右端）にフランジ部分３４が形成されたピース材であり、他端から太径部分の途中に雌ネジ３５が形成されている。この第１棒状部材３Ａの雌ネジ３５に脱着可能に連結（螺合）される第２棒状部材３Ｂは、他端に截頭錘形状の保持部材４が接続され、他方側の型枠Ｂとして用いられる型枠ボード５に当接している。なお、前記第２棒状部材３Ｂは、長さ方向の外周を筒状部材３Ｃで包囲され、打設するコンクリートと接触することがない。
そのため、この間隔保持部材３は、第１棒状部材３Ａと第２棒状部材３Ｂと筒状部材３Ｃとが脱着可能に一体化された構成であり、第２棒状部材３Ｂと保持部材４は、コンクリートの打設、硬化後に容易に抜き出すことができる。 The spacing member 3 in the first embodiment is appropriately selected according to the distance between the molds, that is, the thickness of the concrete to be placed. As shown in FIG. The male screw 31 formed on the end edge (left end in the drawing) of the first rod-shaped member 3A located in the space is arranged in the fastening portion 14. This rod-shaped member 3A is a piece material in which a large-diameter portion 33 is formed through an enlarged portion 32 from a male screw 31 to which a nut 7 is fastened, and a flange portion 34 is formed at the other end (right end in the drawing). Yes, a female screw 35 is formed in the middle of the large diameter portion from the other end. The second rod-shaped member 3B, which is detachably connected (screwed) to the female screw 35 of the first rod-shaped member 3A, has a truncated pyramid-shaped holding member 4 connected to the other end and serves as a mold B on the other side. It is in contact with the formwork board 5 used. The second rod-shaped member 3B is surrounded by the cylindrical member 3C on the outer periphery in the length direction and does not come into contact with the concrete to be placed.
Therefore, the interval holding member 3 has a configuration in which the first rod-like member 3A, the second rod-like member 3B, and the cylindrical member 3C are integrated so as to be detachable. The second rod-like member 3B and the holding member 4 are made of concrete. Can be easily extracted after being placed and cured.

この第１実施例では、締着部１４として、間隔保持部材３と連結するための構成として、螺着（螺合）を採用し、間隔保持部材３の端縁に形成した雄ネジが締着可能な雌ネジを有する六角ナット７を配置する構成とした（Ｌ字状片１５を形成して空間部を形成して六角ナット７を取り付けて締着部１４とした）。
なお、この間隔保持部材３は、前述の構成、即ち複数部材を連結した構成でもよいし、図３（ｅ）の上段に示すように分割タイプでない間隔保持部材３"を用いてもよい。 In the first embodiment, as the fastening portion 14, screwing (screwing) is employed as a configuration for connecting to the spacing member 3, and a male screw formed on the edge of the spacing member 3 is fastened. The hexagon nut 7 having a possible female screw is arranged (the L-shaped piece 15 is formed to form a space portion, and the hexagon nut 7 is attached to form the fastening portion 14).
The spacing member 3 may have the above-described configuration, that is, a configuration in which a plurality of members are connected, or a spacing member 3 ″ that is not a split type may be used as shown in the upper part of FIG.

前記構成の支持材１の両フランジ１１，１２間に保持される型枠パネル２としては、コンクリートＣ打設時に変形しない複層（積層）板を採用した。
この第１実施例では、最表面側断熱材２Ａとしてフレキ板を、中間断熱材２Ｂとして発泡材を、内側断熱材２Ｃとしてケイカル板を用いている。これらのうち、フレキ板２Ａ、ケイカル板２Ｃは曲げ強度の高い繊維強化セメント板であるため、積層板２全体としての曲げ強度も高いものであり、コンクリートＣの打設圧力に対しても変形等を生ずることがない。
なお、この積層板である型枠パネル２の作製に際しては、フレキ板２Ａとケイカル板２Ｃの間に発泡樹脂を注入する等の方法もあるし、個別に作製したフレキ板２Ａと発泡板材２Ｂとケイカル板２Ｃとを単に積層（接合）する方法でもよく、特にその作製方法を限定するものではない。 As the formwork panel 2 held between the flanges 11 and 12 of the support member 1 having the above-described structure, a multilayer (laminated) plate that does not deform when the concrete C is placed is adopted.
In the first embodiment, a flexible plate is used as the outermost surface side heat insulating material 2A, a foam material is used as the intermediate heat insulating material 2B, and a calcium plate is used as the inner heat insulating material 2C. Of these, the flexible plate 2A and the calcium plate 2C are fiber reinforced cement plates having a high bending strength, so that the bending strength of the laminated plate 2 as a whole is also high, and deformation or the like with respect to the concrete C placing pressure. Will not occur.
In the production of the formwork panel 2 which is the laminated plate, there is a method of injecting a foamed resin between the flexible plate 2A and the calcium plate 2C, or the individually prepared flexible plate 2A and the foamed plate material 2B. A method of simply laminating (joining) the calcium plate 2C may be used, and the manufacturing method thereof is not particularly limited.

そして、この第１実施例では、前記支持材１の内側フランジ１２（孔１２１）から型枠パネル２に固定ビス６を打ち込んで保持強度を向上させている。この固定ビス６としては、図３（ｆ）に示すように十字溝が形成された平坦状頭部を有するものを使用したが、半球状頭部を有する固定ビス６'を用いてもよい。 And in this 1st Example, the fixed screw | thread 6 is driven into the formwork panel 2 from the inner side flange 12 (hole 121) of the said support material 1, and the holding strength is improved. As the fixing screw 6, as shown in FIG. 3 (f), a screw having a flat head formed with a cross groove is used, but a fixing screw 6 'having a hemispherical head may be used.

このように、本発明の支持材１は、外側フランジ１１と内側フランジ１２との間に型枠パネル２の端縁を保持することができるため、型枠パネル２として多種の外装材や断熱材を適用することができる。
また、型枠パネル２の内側にて間隔保持部材３と連結する構成であるため、型枠パネル２が適正位置に保持される打設を可能とし、ノロの漏れ出しをも防止できる。そのため、足場、バタ材等を不要或いは最小限とすることができ、全体的な工事コストを抑制することができる。 Thus, since the support material 1 of the present invention can hold the edge of the formwork panel 2 between the outer flange 11 and the inner flange 12, various kinds of exterior materials and heat insulating materials can be used as the formwork panel 2. Can be applied.
Moreover, since it is the structure connected with the space | interval holding | maintenance member 3 inside the formwork panel 2, the placement which the formwork panel 2 is hold | maintained in an appropriate position is enabled, and it can also prevent the leakage of a slot. Therefore, a scaffold, a butterfly material, etc. can be made unnecessary or minimized, and the overall construction cost can be suppressed.

図４（ａ）に示す第２実施例の支持材１'は、外側フランジ１１、内側フランジ１２、及びウエブ１３については、前記第１実施例とほぼ同様であるから、図面に同一符号を付して説明を省略する。
また、この第２実施例でもウエブ１３の裏面側へ略Ｌ字状に突出するＬ字状片１５'を形成する点、該Ｌ字状片１５'の孔１５２を形成する点では前記第１実施例と共通であるが、該Ｌ字状片１５'は、横片部分が厚肉に形成され、単なる通孔ではなく、その内周面に雌ねじが形成された構成であって、前記第１実施例のようにナット等を用いることなくこの横片部分が締着部１４'を形成している構成である。
したがって、図４（ｂ）に示すように前記第１実施例とほとんど同様に間隔保持部材３を連絡することができ、コンクリート壁体の構築に利用することができる。 The support material 1 ′ of the second embodiment shown in FIG. 4 (a) is substantially the same as the first embodiment with respect to the outer flange 11, the inner flange 12, and the web 13, so the same reference numerals are given to the drawings. Therefore, the description is omitted.
Also in the second embodiment, the first shape is the point that the L-shaped piece 15 ′ protruding substantially L-shaped on the back side of the web 13 is formed and the hole 152 of the L-shaped piece 15 ′ is formed. Although common to the embodiment, the L-shaped piece 15 'has a configuration in which a lateral piece portion is formed thick and a female screw is formed on an inner peripheral surface thereof instead of a simple through hole. As in the first embodiment, the lateral piece portion forms a fastening portion 14 'without using a nut or the like.
Therefore, as shown in FIG. 4B, the spacing member 3 can be communicated in almost the same manner as in the first embodiment, and can be used to construct a concrete wall.
