【発明の属する技術分野】
本発明は気泡コンクリートを打設する構造物に対し、残存型枠の枠組方法に関する。
【０００２】
【従来の技術】
従来、コンクリート製の構造物を施工する際に、型枠としてコンクリート製パネルの残存型枠を使用して枠組し、打設したコンクリートが固化後に型枠がコンクリート構造物の表面に残存させ、型枠を撤去する必要がない工法が知られている。そしてこの工法は施工の容易さ、工賃の安さ及び廃材が出ない等の理由で近年注目されている。
【０００３】
この残存型枠工法において、残存型枠（２）の枠組方法は図８に示すように、数回に分けて打設するコンクリートの打設高さに対応して順次上方に向って枠組するのであるが、それは予め基礎コンクリート（１）に鉄筋杭（11）を差し込んで固定させ、次いで基礎コンクリート（１）上に打設コンクリート（Ａ）の高さに応じて複数枚の残存型枠（２）を段積し、連結金具（３）で連結固定し、且つ少なくとも、鉄筋杭（11）と連結金具（３）間を支柱（12）で支持させ枠組し、１回目のコンクリート（Ａ）を打設すると共に、それが固化しない間に打設コンクリート（Ａ）上面に鉄筋杭（11）を差し込んで置く。そして打設コンクリート（Ａ）が固化後、前記と同様な枠組し、２回目のコンクリート（Ａ）を打設し、以後同様な枠組及びコンクリート（Ａ）の打設を繰返しながら、構造物の高さになるまで枠組する方法であった。
【０００４】
【発明が解決しようとする課題】
上記従来の枠組方法は、打設するコンクリート（Ａ）がポルトランドセメントに骨材として砂や砂利等を混入させたペースト状のもので、比重も重く、且つ硬く固化する一般的なコンクリート（Ａ）を対象とする方法であるから、鉄筋杭（11）が固化したコンクリート（Ａ）に強固に固着されているため、抜けたり傾斜したりせず、コンクリート打設時の側圧にも従来の枠組方法で充分対応できるのである。しかしながら打設コンクリート（Ａ）が気泡コンクリートの場合には比重も軽く、且つ硬く固化しないため、従来の鉄筋杭（11）では、段積した残存型枠に加わる打設コンクリート（Ａ）の側圧により鉄筋杭（11）が抜けたり、傾斜したりして移動してしまい、残存型枠がずれたり、あるいは崩れたりする危険を伴うという問題を有していた。
【０００５】
本発明は上記従来の問題点を解消するものであり、気泡コンクリート製構造物の施工において、打設コンクリートが固化後に軟弱又は軟質であっても残存型枠の枠組が確実にでき、打設コンクリートの側圧に充分耐えられる残存型枠の枠組方法を提供することを目的とする。
【０００６】
本発明の他の目的は、、打設コンクリート中に埋設される残存型枠の支持する部材等に錆の発生がなく、耐久性の高い残存型枠の枠組方法を提供するにある。
【０００７】
【課題を解決するための手段】
上記課題を解決するために本発明は、予め気泡コンクリート（Ａ）打設内に多数本の主柱（４）を、下端の基礎コンクリート（１）に垂設固着し、次いでパネル状の残存型枠（２）を一定の高さに段積して接続すると共に、前記残存型枠（２）と前記主柱（４）との間を前支柱（５）で接続固定し、且つ前記主柱（４）に対して前記残存型枠（２）と反対側には埋設抵抗部材（６）を載置し、該埋設抵抗部材（６）と前記主柱（４）との間を後支柱（７）で接続させて前記残存型枠（２）を枠組し、以後この枠組を順次前記気泡コンクリート（Ａ）を一定高さに打設しながら所定の高さまで行う。
【０００８】
前記主柱（４）を上方に連結部材（９）で連結し伸長するのが好ましい。
【０００９】
前記連結部材（９）に２本のソケット（８）を角度を有して固定させ、該ソケット（８）の１本に前記前支柱（５）、他の１本に前記後支柱（７）のそれぞれ一端を挿入し固定ネジ（8a）で固定するのが好ましい。
【００１０】
前記主柱（４）、前記前支柱（５）、前記埋設抵抗部材（６）及び後支柱（７）が、エポキシ樹脂塗料による塗装を施すと共に枠組の際に接続箇所を溶接以外の接合方法で行うのが好ましい。
【００１１】
【発明の実施の形態】
図１は本発明の枠組方法を示す側面図、図２は本発明の枠組方法を示す正面図、図３は本発明の残存型枠の連結状態の説明図、図４は本発明の主柱に取付けた連結部材にソケットを設けた斜視図、図５は本発明の主柱に取付けた連結部材の断面図、図６は本発明の埋設抵抗部材の正面図、図７は本発明の埋設抵抗部材の断面図、図８は従来の枠組方法の説明図である。
【００１２】
先ず本発明の気泡コンクリート（Ａ）を打設するための枠組方法を図１〜図３を基に説明すると、（１）は基礎コンクリートであり、通常施工する構造物の下端部分に設け、構造物の基礎となるものである。（２）はコンクリート製でパネル状の残存型枠であり、これは例えば厚さ３０〜４０mm巾９００〜１２００mm高さ６００mm程度のものが使用される。この残存型枠（２）は基礎コンクリート（１）上に段積し、互いに連結金具（３）で連結するのであるが、この段積は一度に構造物の高さまで段積せず、数回に分けて打設する気泡コンクリート（Ａ）の高さに応じて順次段積するものである。これを更に説明すると、本発明に使用する残存型枠とは、コンクリート製の構造物を施工する際に、そのものが型枠として枠組し、コンクリート打設後にコンクリートの表面に残存するタイプのものであり、その一例としては本発明者が提案した特願平９−２３７６６７号のもの、あるいは特願平１０−７１４０８号のものであるが、この一例ではあくまで代表的なものを例示したものであり、この一例に限定されるものではない。又、連結金具（３）は本発明者が提案した特願平９−２７８１８３号のものを使用するのが好ましいが、これに限定されない。
【００１３】
次に残存型枠（２）を枠組する手順としては、構造物の高さが極めて低い場合を除き始めから構造物の高さまで一度に段積して枠組を完了することはない。つまり、構造物がある程度の高さ、例えば残存型枠（２）を３枚以上段積するような高さの場合には、一度に気泡コンクリート（Ａ）を打設せずに気泡コンクリート（Ａ）の打設高を６００mm〜１２００mm以内にするのが危険性の面で好ましく、そのため数回に分けて気泡コンクリート（Ａ）を打設するようにしている。このように残存型枠（２）は一回で打設する気泡コンクリート（Ａ）の高さ、つまり打設高に合せて段積し、それを順次繰返して上方に構造物の高さまで段積するのである。
【００１４】
（４）は予め基礎コンクリート（１）に下端を埋設し、垂直に固着させた主柱であり、該主柱（４）は鉄製のパイプ，鉄筋，形鋼等が使用される。そしてこの主柱（４）は構造物の高さよりも多少短くし、打設コンクリート内に埋設するようにしている。又、この主柱（４）は気泡コンクリート（Ａ）の打設内で残存型枠（２）と並行に多数本並べたものである。
【００１５】
（５）は残存型枠（２）と主柱（４）との間を接続し、残存型枠（２）を主柱（４）に支持し固定させる前支柱であり、通常鉄筋棒を使用するが、他に鉄パイプ，平鋼，鉄棒等でもよい。
【００１６】
（６）は主柱（４）に対して残存型枠（２）の反対側に載置した埋設抵抗部材である。該埋設抵抗部材（６）は打設する気泡コンクリート（Ａ）に埋設された際に所定の引張抵抗を有する形状のものであり、引張り方向に一定の面積を持つ形状であればよく、例えば図６、図７で示したものは板状のものであり、板部材（6a）に接続管（6b）及び固定ネジ（6c）を備えている。その他としてはアングル、形鋼等でもよい。この埋設抵抗部材（６）は始めは基礎コンクリート（１）上又は基礎コンクリート（１）外の地面上に載置させ、１回目の気泡コンクリート（Ａ）を打設後は、以後打設した気泡コンクリート（Ａ）上に載置する。
【００１７】
（７）は主柱（４）と埋設抵抗部材（６）との間を接続する後支柱であり、前記した前支柱（５）と多少の長さや支持角度が異なるにしても基本的に同じものである。
【００１８】
本発明の残存型枠の枠組方法は以上のものを使用して枠組するものであり、この枠組の手順を以下に説明する。先ず基礎コンクリート（１）上に残存型枠（２）を数枚を段積し、連結金具（３）で連結させる。次いで段積した残存型枠（２）と主柱（４）との間を前支柱（５）で接続し、残存型枠（２）を主柱（４）で支持して固定させる。この際に前支柱（５）の一端は連結金具（３）に螺合したソケット（3a）と連結し固定ネジ（3b）で固定させ（図３参照）、他端は主柱（４）に取付けたソケット（８）に差し込み固定ネジ（8a）で固定させる（図４参照）。又、ソケット（８）の高さ位置は連結金具（３）の高さよりも低い位置に設けてあり、気泡コンクリート（Ａ）を打設した際に埋設させる。そして主柱（４）に対して残存型枠（２）と反対側となる後方の地面上に埋設抵抗部材（６）を載置し、この埋設抵抗部材（６）と主柱（４）と間を後支柱（７）で接続して残存型枠（２）の枠組が成される。この枠組状態にて１回目の気泡コンクリート（Ａ）を打設する。そして１回目の打設した気泡コンクリート（Ａ）が固化後に、２回目以後の気泡コンクリート（Ａ）を打設するための枠組を前記した１回目と同様な枠組で順次構造物の高さまで行えばよい。この際に埋設抵抗部材（６）は固化した気泡コンクリート（Ａ）上に載置される。
【００１９】
又、主柱（４）は一端に連結部材（９）を固着した一定長さとし、その他端を連結部材（９）で上方に連結しながら所定の長さまで伸長させるのが組立及び運搬の面で好ましい。この連結部材（９）は図５に示すように短管（9a）に固定ネジ（9b）を設けたもので、短管（9a）の上から差し込まれた主柱（４）を固定ネジ（9b）で固定することにより連結される。
【００２０】
更に図４に示すように前記連結部材（９）に２本のソケット（８）を角度を有して設け、該ソケット（８）の１本に前支柱（５）を、他の１本に後支柱（７）のそれぞれ一端を挿入し固定ネジ（8a）で固定するのが、作業性もよく枠組が容易となる。尚、ソケット（８）の取付角度は前支柱（５）及び後支柱（７）の接続する傾斜角度に合せている。
【００２１】
又、本発明では主柱（４）、前支柱（５）、埋設抵抗部材（６）、及び後支柱（７）はエポキシ樹脂塗料による塗装を施すのが、コンクリート内に埋設されても錆に強く好ましい。そして枠組の際には接続箇所を溶接以外の接続方法で行うのが錆の発生を防止するため好ましく、例えばソケットとネジとで接続させればよい。尚、（10）は補強用の横杆である。
【００２２】
【発明の効果】
本発明は、下端の基礎コンクリート（１）に垂設させた主柱（４）と段積した残存型枠（２）とを前支柱（５）で接続し、且つ主柱（４）と埋設抵抗部材（６）とを後支柱（７）で接続し、段積した残存型枠（２）を前記主柱（４）と埋設抵抗部材（６）とで支持する点に特徴がある。この特徴を活かすことにより、従来、気泡コンクリート（Ａ）を打設するための残存型枠（２）の枠組は、気泡コンクリート（Ａ）の軟弱性で段積した残存型枠（２）を支持するのに難しかったが、基礎コンクリート（１）から垂設した主柱（４）と、気泡コンクリート（Ａ）内に埋設されると強い引張抵抗を発揮する埋設抵抗部材（６）とにより気泡コンクリート（Ａ）の打設でも強固に残存型枠（２）の枠組ができる。特に高さのある構造物、例えば擁壁に対して、気泡コンクリート（Ａ）を数回に分けて打設する場合でも確実に枠組が可能となった。
【００２３】
又、主柱（４）が連結で上方に伸長できるため、始めから構造物の高さまでのものを用意することなく、一定長さのものを数本、気泡コンクリート（Ａ）の打設回数に合せて継ぎ足せばよく、施工現場に搬入するのに便利となり、且つ種々の高さの構造物に対応可能となる。
【００２４】
更に本発明では、主柱（４）、前支柱（５）、埋設抵抗部材（６）及び後支柱（７）がエポキシ樹脂塗料で塗装され、且つそれらの各接続箇所を溶接以外の接続方法で行うため、気泡コンクリート（Ａ）内に埋設されても錆の発生が殆どない。従って気泡コンクリート（Ａ）は雨水の浸透性がよく内部に錆が発生し易く、その錆が残存型枠（２）の表面に流れ出して外見的に構造物の見栄えを悪くし、又、時として残存型枠（２）が落下する恐れがあるが、本発明ではそのようなことが防止され、長年に渡り見栄えのよい構造物を維持できる。

BACKGROUND OF THE INVENTION
The present invention relates to a method for framing a remaining mold for a structure in which cellular concrete is placed.
[0002]
[Prior art]
Conventionally, when a concrete structure is constructed, the remaining formwork of the concrete panel is used as a formwork, and the formwork remains on the surface of the concrete structure after the cast concrete is solidified. Construction methods that do not require the removal of the frame are known. This construction method has attracted attention in recent years because of its ease of construction, low construction cost, and no waste materials.
[0003]
In this residual mold method, the frame method of the residual mold (2) is as shown in FIG. 8, because the frames are sequentially framed upward corresponding to the concrete placement height to be placed in several times. There are two types of residual formwork (2) depending on the height of the concrete (A) to be placed on the foundation concrete (1). ), And are connected and fixed with the connecting bracket (3), and at least the frame between the reinforcing bar pile (11) and the connecting bracket (3) is supported by the column (12), and the first concrete (A) is While placing, the reinforcing steel pile (11) is inserted and placed on the upper surface of the placed concrete (A) while it does not solidify. Then, after the cast concrete (A) is solidified, the same frame as described above is placed, the second concrete (A) is cast, and thereafter the same frame and concrete (A) are repeatedly cast, It was a method of framing until it came.
[0004]
[Problems to be solved by the invention]
In the above conventional framework method, the concrete (A) to be cast is a paste-like material in which sand or gravel is mixed as an aggregate with Portland cement, and the specific concrete is heavy and solidified. Since the reinforcing bar pile (11) is firmly fixed to the solidified concrete (A), it does not come off or incline, and the conventional framing method also applies to the side pressure during concrete placement. Is enough. However, when the cast concrete (A) is cellular concrete, the specific gravity is also light and does not harden and solidify. Therefore, in the conventional reinforcing steel pile (11), due to the side pressure of the cast concrete (A) applied to the stacked residual formwork There was a problem that the reinforcing bar pile (11) moved by being pulled out or inclined, and there was a risk that the remaining formwork would be displaced or collapsed.
[0005]
The present invention solves the above-mentioned conventional problems, and in the construction of a cellular concrete structure, even if the cast concrete is soft or soft after solidification, the framework of the remaining formwork can be ensured, and the cast concrete It is an object of the present invention to provide a method for framing a remaining mold that can sufficiently withstand the lateral pressure.
[0006]
Another object of the present invention is to provide a method for framing the remaining formwork which is free from rust on the members and the like supported by the remaining formwork embedded in the cast concrete and has high durability.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention has a structure in which a large number of main pillars (4) are suspended and fixed in advance to the foundation concrete (1) at the lower end in the cellular concrete (A) placement, and then the panel-like residual mold. The frame (2) is stacked and connected at a fixed height, and the remaining mold (2) and the main pillar (4) are connected and fixed by a front support (5), and the main pillar An embedded resistance member (6) is placed on the opposite side of the remaining formwork (2) with respect to (4), and a rear strut (between the embedded resistance member (6) and the main column (4) ( In step 7), the remaining mold (2) is framed, and then the frame is sequentially raised to a predetermined height while placing the cellular concrete (A) at a constant height.
[0008]
It is preferable that the main pillar (4) is connected upward by a connecting member (9) and extends.
[0009]

The remaining formwork (2) is stacked on the foundation concrete (1) and connected to each other by the connecting metal fitting (3), but this stacking does not stack up to the height of the structure at once. Are stacked in order according to the height of the cellular concrete (A) to be placed separately. To explain this further, the remaining formwork used in the present invention is a type that remains on the surface of concrete after being placed as a formwork when a concrete structure is constructed. One example is the one of Japanese Patent Application No. 9-237667 proposed by the present inventor or the one of Japanese Patent Application No. 10-71408. In this example, a representative one is only illustrated. However, the present invention is not limited to this example. Moreover, although it is preferable to use the thing of Japanese Patent Application No. 9-278183 which the inventor proposed for the connection metal fitting (3), it is not limited to this.
[0013]
Next, as a procedure for framing the remaining mold (2), the frame is not completed by stacking all the way from the beginning to the height of the structure except when the height of the structure is extremely low. That is, when the structure has a certain height, for example, a height that stacks three or more remaining molds (2), the cellular concrete (A) is not placed at once without placing the cellular concrete (A). ) Is preferably in the range of 600 mm to 1200 mm from the viewpoint of danger. For this reason, the cellular concrete (A) is cast in several times. In this way, the remaining formwork (2) is stacked according to the height of the cellular concrete (A) to be placed at one time, that is, according to the placement height, and is repeatedly stacked up to the height of the structure. To do.

The embedded resistance member (6) has a shape having a predetermined tensile resistance when embedded in the cellular concrete (A) to be placed, and may have any shape having a certain area in the tensile direction. 6, what is shown in FIG. 7 is a plate-like one, and a plate member (6a) is provided with a connecting pipe (6b) and a fixing screw (6c). In addition, an angle, a shape steel, etc. may be sufficient. This embedded resistance member (6) is initially placed on the foundation concrete (1) or on the ground outside the foundation concrete (1), and after the first aerated concrete (A) is placed, the bubbles that have been placed thereafter. Place on concrete (A).
[0017]
(7) is a rear column that connects the main column (4) and the embedded resistance member (6), and is basically the same as the above-mentioned front column (5) even if it is slightly different in length and support angle. Is.
[0018]
The frame forming method of the remaining mold according to the present invention is to frame using the above, and the procedure of this frame will be described below. First, several residual molds (2) are stacked on the foundation concrete (1), and are connected by a connecting metal fitting (3). Next, the stacked residual formwork (2) and the main pillar (4) are connected by the front strut (5), and the residual formwork (2) is supported and fixed by the main pillar (4). At this time, one end of the front strut (5) is connected to a socket (3a) screwed into the connecting metal fitting (3) and fixed with a fixing screw (3b) (see FIG. 3), and the other end is connected to the main column (4). Insert the socket (8) and fix it with the fixing screw (8a) (see Fig. 4). Moreover, the height position of the socket (8) is provided at a position lower than the height of the connecting metal fitting (3), and is embedded when cellular concrete (A) is placed. Then, an embedded resistance member (6) is placed on the ground on the rear side opposite to the remaining mold (2) with respect to the main column (4), and the embedded resistance member (6), the main column (4), and A frame of the remaining mold (2) is formed by connecting the spaces with the rear strut (7). In this framework state, the first cellular concrete (A) is placed. Then, after the aerated concrete (A) placed for the first time is solidified, a framework for placing the aerated concrete (A) for the second and subsequent times is sequentially made up to the height of the structure with the same framework as described above. Good. At this time, the embedded resistance member (6) is placed on the solidified foam concrete (A).
[0019]
The main pillar (4) has a fixed length with a connecting member (9) fixed to one end, and the other end is connected to the connecting member (9) upward and extended to a predetermined length in terms of assembly and transportation. preferable. As shown in FIG. 5, the connecting member (9) has a short pipe (9a) provided with a fixing screw (9b), and the main column (4) inserted from above the short pipe (9a) is fixed to the fixing screw (9). Connected by fixing in 9b).
[0020]
Further, as shown in FIG. 4, the connecting member (9) is provided with two sockets (8) at an angle, and one of the sockets (8) has a front support column (5) and the other one. Inserting one end of each of the rear struts (7) and fixing with the fixing screws (8a) improves workability and facilitates the framework. The mounting angle of the socket (8) is adjusted to the inclination angle at which the front strut (5) and the rear strut (7) are connected.
[0021]
In the present invention, the main pillar (4), the front strut (5), the embedded resistance member (6), and the rear strut (7) are coated with an epoxy resin paint. Strongly preferred. And in the case of a frame, it is preferable to connect the connecting portion by a connecting method other than welding in order to prevent the occurrence of rust. For example, the connecting portion may be connected by a socket and a screw. Note that (10) is a reinforcing reed.
[0022]
【The invention's effect】
In the present invention, the main pillar (4) suspended from the foundation concrete (1) at the lower end and the remaining formwork (2) stacked are connected by the front strut (5) and embedded in the main pillar (4). The resistance member (6) is connected to the rear column (7), and the remaining stacked form (2) is supported by the main column (4) and the embedded resistance member (6). By making use of this feature, the framework of the remaining mold (2) for placing the cellular concrete (A) conventionally supports the residual mold (2) stacked with the softness of the cellular concrete (A). Although it was difficult to do, cellular concrete is composed of the main pillar (4) suspended from the foundation concrete (1) and the embedded resistance member (6) that exhibits strong tensile resistance when embedded in the cellular concrete (A). Even in the placement of (A), the framework of the remaining mold (2) can be firmly formed. Particularly when a cellular concrete (A) is placed in several times on a structure having a height, for example, a retaining wall, a frame can be reliably formed.
[0023]
In addition, since the main pillar (4) can be connected and extended upward, it is possible to increase the number of foamed concrete (A) by placing several pieces of a certain length without preparing one from the beginning to the height of the structure. It is sufficient to add them together, which makes it convenient to carry in to the construction site, and can cope with structures of various heights.
[0024]
Furthermore, in the present invention, the main pillar (4), the front strut (5), the embedded resistance member (6), and the rear strut (7) are painted with an epoxy resin paint, and their connection points are connected by a connection method other than welding. For this reason, rust is hardly generated even when embedded in cellular concrete (A). Therefore, the cellular concrete (A) has good rainwater permeability and is prone to rust inside, and the rust flows out to the surface of the remaining formwork (2) to make the structure look bad. Although there is a possibility that the remaining formwork (2) may fall, in the present invention, such a situation is prevented and a structure that looks good for many years can be maintained.
