Description

コンクリート構造物の施工方法及びコンクリート構造物用型枠パネルConstruction method of concrete structure and formwork panel for concrete structure
　本発明は、コンクリート構造物の施工方法とコンクリート構造物に用いられる型枠パネルに関し、ことに薄板金属パネルを型枠パネルとして用いて埋め殺して用いるコンクリート構造物の施工方法とそれに用いられる型枠パネルに関する。 TECHNICAL FIELD The present invention relates to a method for constructing a concrete structure and a formwork panel used for the concrete structure, in particular, a method for constructing a concrete structure to be used by burying and using a thin metal panel as a formwork panel, and a formwork used for the method. Regarding panels.
　従来、建物工事でコンクリート壁を形成する際には、木製などの型枠パネルを用いて型枠を構築し、その型枠内にコンクリートを打設して養生・硬化させ、硬化後型枠パネルを取り外してコンクリート壁を形成していた。このような型枠は、通常、コンクリート壁面構築後取り外して再使用している。しかしながら、コンクリート型枠の構築並びに取外しは相当の手間を要し、コスト上昇の一因となっている。
　これに対して近年では、工数を削減し且つ環境保護に資するために、金属薄板を角波形状に形成した金属製の型枠パネルを用いて型枠を構築し、その型枠パネルをコンクリート硬化後に埋め殺し状態で放置するようにする方法が提案されている。 Conventionally, when forming concrete walls in building construction, formwork is constructed using formwork panels such as wood, and concrete is placed in the formwork and cured and hardened. Removed and formed a concrete wall. Such a formwork is usually removed and reused after construction of a concrete wall surface. However, the construction and removal of the concrete formwork requires considerable effort and contributes to an increase in cost.
On the other hand, in recent years, in order to reduce man-hours and contribute to environmental protection, a formwork was constructed using a metal formwork panel in which a metal thin plate was formed into a square wave shape, and the formwork panel was hardened with concrete. There has been proposed a method of leaving it in a buried state later.
　例えば、コンクリート壁形成時に形枠として機能し、形成後に埋め殺し状態で配設される角波板の型枠パネルであって、角波における凸条が外側に向けて断面幅が大きくなり凹溝が蟻溝形状となる形状に構成された型枠パネルと、これを用いた発泡合成樹脂層を備えたコンクリート壁構造が（特許文献１参照）、また、凹溝と凸条を交互に形成した波形パネルの内面に平坦な内面板を一体に接合した型枠パネルと、該型枠パネルの下端を受け入れるランナーと型枠パネルの上端を受け入れるキャップとからなるコンクリート型枠と、これを用いたコンクリート壁の施工方法（特許文献２参照）が報告されている。
　さらに、間隔を設けて組立てられる構築用型枠内にコンクリートを打設し、構築用型枠とコンクリートを一体化するコンクリート建物外壁構造体の構築用型枠であって、断熱材により形成される構築用型枠パネル本体と、該構築用型枠パネル本体の一側面に対し、空隙を設けて形成される網目状部とを備えた構築用型枠パネルと、これを用いたコンクリート外壁の構築方法（特許文献３参照）が報告されている。
　さらにまた、建造物の壁の高さに応じて高さ調整できるようにした断熱板に、該断熱板の大きさ及び形状に合わせて枠内に縦に１乃至複数の木桟を配設して外枠を形成した木桟枠を埋め込み、裏面より固着用台座を介在させて釘止めしてなり、前記木桟枠の埋め込み面を外面とする型枠を形成してコンクリートを打設し、釘の頭部を含む前記固着用台座をコンクリート躯体壁に埋め込み固着したコンクリート建造物の壁下地用型枠パネル（特許文献４参照）が報告されている。 For example, a square wave plate form panel that functions as a formwork when forming a concrete wall and is disposed in a buried state after formation, and the ridges in the square wave have a cross-sectional width that increases toward the outside, resulting in a concave groove. A formwork panel configured in a dovetail shape and a concrete wall structure including a foamed synthetic resin layer using the dovetail groove shape (see Patent Document 1), and also formed grooves and ridges alternately. A concrete formwork comprising a formwork panel in which a flat inner face plate is integrally joined to the inner face of the corrugated panel, a runner that accepts the lower end of the formwork panel, and a cap that accepts the upper end of the formwork panel, and concrete using the same A wall construction method (see Patent Document 2) has been reported.
Furthermore, it is a construction form for a concrete building outer wall structure in which concrete is placed in a construction form that is assembled with a gap and the construction form and the concrete are integrated, and is formed by a heat insulating material. Construction form panel comprising a construction form panel main body, and a mesh-like part formed by providing a gap on one side of the construction form panel main body, and construction of a concrete outer wall using the construction form panel A method (see Patent Document 3) has been reported.
Furthermore, one or more wooden crosspieces are vertically arranged in the frame in accordance with the size and shape of the heat insulating plate on the heat insulating plate which can be adjusted in height according to the height of the wall of the building. The wooden frame that forms the outer frame is embedded, nailed by interposing a fixing base from the back side, concrete is formed by forming a mold with the embedded surface of the wooden frame as the outer surface, A formwork panel for a wall foundation of a concrete building in which the fixing base including a nail head is embedded and fixed in a concrete frame wall has been reported (see Patent Document 4).
　しかしながら、これら従来の壁用型枠パネルでは、そのパネルとコンクリート躯体との接合強度が必ずしも充分で無いという問題があった。パネルとコンクリート躯体との接着強度が充分で無いとコンクリートにひび割れができやすく、壁面構造に充分な面内剛性が得られないという問題があった。 However, these conventional wall form panels have a problem that the bonding strength between the panel and the concrete frame is not always sufficient. If the adhesive strength between the panel and the concrete frame is not sufficient, there is a problem that the concrete is easily cracked and sufficient in-plane rigidity cannot be obtained for the wall structure.

　以上に述べたように、従来の型枠パネルを埋め殺し状態で用いたコンクリート構造物の例では、型枠パネルとコンクリート躯体との接合強度が必ずしも充分ではないという問題があった。 As described above, in the example of a concrete structure in which a conventional formwork panel is buried and killed, there is a problem that the joint strength between the formwork panel and the concrete frame is not always sufficient.
　本発明は、この問題を解決して、埋め殺し状態で用いる型枠パネルにおいて、比較的簡単な手法で型枠パネルとコンクリート躯体との接合強度を高め、コンクリート構造物の面内剛性を向上するとともに、この型枠パネルを用いたコンクリート構造物の施工方法を実現することを目的とする。 The present invention solves this problem and, in a formwork panel used in a buried state, increases the bonding strength between the formwork panel and the concrete frame by a relatively simple method, and improves the in-plane rigidity of the concrete structure. And it aims at realizing the construction method of the concrete structure using this formwork panel.
　上記課題を解決するため、本発明のコンクリート構造物の施工方法は、コンクリート躯体と、そのコンクリート躯体の表面に埋め殺し状態で配設される型枠パネルとを備えたコンクリート構造物の施工方法であって、その長さ方向に伸びる複数の凸条が幅方向に互いに平行に並設され、この凸条の上面にはその上面に対して垂直に立設する複数の押上げ片が設けられた１対の前記型枠パネルを、その上面側を対向する前記型枠パネル側に向けてコンクリート構造物の厚みに相当する間隔をおいて配設し、この配設された１対の前記型枠パネル間にコンクリートを打設して前記型枠パネルを埋め殺し状態にして構成することを特徴とする。 In order to solve the above problems, a concrete structure construction method of the present invention is a concrete structure construction method comprising a concrete frame and a formwork panel disposed in a buried state on the surface of the concrete frame. A plurality of ridges extending in the length direction are juxtaposed in parallel with each other in the width direction, and a plurality of push-up pieces standing upright with respect to the upper surface are provided on the upper surface of the ridges. A pair of the formwork panels are arranged at an interval corresponding to the thickness of the concrete structure with the upper surface side facing the formwork panel side facing each other. It is characterized in that concrete is placed between the panels so that the formwork panel is filled and killed.
　また、本発明のコンクリート構造物の施工方法は、コンクリート躯体と、そのコンクリート躯体の表面に埋め殺し状態で配設される型枠パネルとを備えたコンクリート構造物の施工方法であって、その長さ方向に伸びる複数の凸条が幅方向に互いに平行に並設された１対の前記型枠パネルを、その上面側を対向する前記型枠パネル側に向けてコンクリート構造物の厚みに相当する間隔をおいて配設し、この配設された１対の前記型枠パネル間にコンクリートを打設して前記型枠パネルを埋め殺し状態にして構成することを特徴とする。 In addition, the concrete structure construction method of the present invention is a concrete structure construction method including a concrete frame and a formwork panel disposed in a buried state on the surface of the concrete frame, Corresponding to the thickness of a concrete structure, a pair of the formwork panels in which a plurality of ridges extending in the lengthwise direction are arranged in parallel to each other in the width direction is directed to the formwork panel side facing the upper surface side. It is characterized in that it is arranged at intervals, and concrete is placed between the arranged pair of formwork panels so that the formwork panels are buried.
　ここで、必要に応じて前記型枠パネルの両端部に、断面コの字型の補助部材を装着することを特徴とする。 Here, if necessary, auxiliary members having a U-shaped cross section are attached to both ends of the formwork panel.
　上記課題を解決するため、本発明の型枠パネルは、コンクリート構造物の形成時に型枠として機能し、形成後に埋め殺し状態で用いられる金属薄板から成る型枠パネルであって、その長さ方向に伸びる複数の凸条がその幅方向に互いに平行に並設され、この凸条の上面には、その上面に対して垂直に立設する複数の押上げ片が設けられていることを特徴とする。 In order to solve the above problems, a formwork panel according to the present invention is a formwork panel made of a thin metal plate that functions as a formwork during formation of a concrete structure and is used in a buried state after formation.

　以下、図面を参照しつつ本発明に係るコンクリート構造物の施工方法とコンクリート構造物に用いられる型枠パネルについて説明する。なお、以下の説明は発明をより深く理解するためのものであって、特許請求の範囲を限定するためのものではない。 Hereinafter, a construction method of a concrete structure according to the present invention and a formwork panel used for the concrete structure will be described with reference to the drawings. The following description is for the purpose of understanding the invention more deeply and is not intended to limit the scope of the claims.
　図１は、本発明の建築用の型枠パネル１の一実施の形態の外観を示す斜視図である。また、図２は、本実施の形態におけるその型枠パネル１の断面図であり、図１のＡ－Ａ断面を表している。
　以下、これらの図を用いて、本実施の形態における型枠パネル１の構成について説明する。 FIG. 1 is a perspective view showing an appearance of an embodiment of an architectural form panel 1 according to the present invention. FIG. 2 is a cross-sectional view of the formwork panel 1 in the present embodiment, and represents a cross section taken along the line AA of FIG.
Hereinafter, the structure of the formwork panel 1 in this Embodiment is demonstrated using these figures.
　図に示すように、型枠パネル１は、鋼製の板形状の材質を、正面略方形状かつ断面略角波形状に折り曲げ、切断加工して成形した埋め殺し型の型枠パネルである。
　例えば、この型枠パネル１の完成品の大きさは、長さ３００～７０００ｍｍ、幅６００ｍｍ、厚さ０．３～０．４ｍｍ程度である。 As shown in the figure, the formwork panel 1 is a buried formwork panel formed by bending and cutting a steel plate-shaped material into a substantially square front shape and a substantially square wave cross section.
For example, the finished product of the form panel 1 has a length of about 300 to 7000 mm, a width of 600 mm, and a thickness of about 0.3 to 0.4 mm.
　このように、パネル鋼板を断面略角波形状に折り曲げることで、型枠パネル１には、互いに平行な複数の凸条１１が所定間隔で並設され、パネル１自体の強度を補強している。
　また、パネル断面を等辺角波型に成形することで、特に表面又は裏面側からの力に対して優れた強度を発揮する。
　なお、本実施の形態においては、この凸条１１の形成方向を型枠パネル１の「長さ方向」とし、型枠パネル１においてその長さ方向に垂直な方向を「幅方向」とする。 In this way, by bending the panel steel plate into a substantially square wave shape in cross section, a plurality of parallel strips 11 are arranged in parallel at a predetermined interval on the formwork panel 1 to reinforce the strength of the panel 1 itself. .
Further, by forming the cross section of the panel into an equilateral angular wave type, particularly excellent strength against the force from the front surface or the back surface side is exhibited.
In the present embodiment, the direction in which the ridges 11 are formed is the “length direction” of the mold panel 1, and the direction perpendicular to the length direction of the mold panel 1 is the “width direction”.
　図に示すように、その凸条１１は、上面１８と、この上面１８の両幅方向に連設されている２面の側面１９とにより構成されている。
　この上面１８の幅方向の長さ及び側面１９の幅方向（奥行き方向）の長さは、１０～２０ｍｍ程度である。
　また、互いに隣接する凸条１１の幅方向の間隔は、１０～５０ｍｍ程度である。 As shown in the figure, the ridge 11 is composed of an upper surface 18 and two side surfaces 19 that are connected in the width direction of the upper surface 18.
The length in the width direction of the upper surface 18 and the length in the width direction (depth direction) of the side surface 19 are about 10 to 20 mm.
Further, the interval in the width direction between adjacent ridges 11 is about 10 to 50 mm.
　また、各凸条１１間の凹面には、所定間隔ごとに、複数の幅方向の断面凸状のリブ１２と、幅方向の断面凹状の溝部１６が、凸条１１に平行に繰り返し形成されている。
　本実施の形態では、幅方向に凸条１１→溝部１６→リブ１２→溝部１６→リブ１２→……→溝部１６→凸条１１→……というように設けられており、凸条１１の幅方向の両側には、溝部１６が連設されている。
　このリブ１２は、幅８～２０ｍｍ程度、高さ３～１０ｍｍ程度で、その幅方向断面が例えば半円弧状に形成されている。
　また、溝部１６は、幅２～１０ｍｍ程度に形成されている。 A plurality of ribs 12 having a convex section in the width direction and grooves 16 having a concave section in the width direction are repeatedly formed in parallel to the convex lines 11 at predetermined intervals on the concave surface between the convex lines 11. Yes.
In the present embodiment, the ridges 11 → grooves 16 → ribs 12 → grooves 16 → ribs 12 → …… → grooves 16 → projections 11 →... Are provided in the width direction. Grooves 16 are continuously provided on both sides in the direction.
The rib 12 has a width of about 8 to 20 mm and a height of about 3 to 10 mm, and a cross section in the width direction is formed in a semicircular arc shape, for example.
The groove 16 is formed with a width of about 2 to 10 mm.
　さらに、凸条１１のパネル幅方向の両端、すなわち、リブ１２とそのリブ１２に隣接する溝部１６との間の境界線上には、所定長の切込み１３が、所定間隔で凸条１１と平行に破線状に設けられている。
　この破線状の切込み１３列に沿って型枠パネル１を所定の角度に折り曲げることにより、型枠のコーナー部分を形成することができるようになっている。
　また、この破線状の切込み１３列に沿って、型枠パネル１を、正逆方向に数回繰り返し折り曲げることにより、型枠パネル１を所望のサイズに容易に切断することができるようになっている。 Further, on the both ends of the ridge 11 in the panel width direction, that is, on the boundary line between the rib 12 and the groove portion 16 adjacent to the rib 12, a predetermined length of the notch 13 is parallel to the ridge 11 at a predetermined interval. It is provided in the form of a broken line.
By bending the formwork panel 1 at a predetermined angle along the 13 rows of cut lines in the broken line shape, corner portions of the formwork can be formed.
In addition, the formwork panel 1 can be easily cut into a desired size by repeatedly bending the formwork panel 1 several times in the forward / reverse direction along the 13 rows of incisions in the broken line shape. Yes.
　また、その切込み１３は、微小幅、所定長の型枠パネル１の表裏に貫通した切込みであり、コンクリートやモルタルを打設後に、その切込み１３から液状のコンクリートやモルタルが漏出しないように形成されている。また、そのコンクリートやモルタルに含まれる余分な水分が排出可能な程度に、その切込み１３の幅が形成されている。
　例えば、この切込み１３は、幅が０．３～１ｍｍ程度、長さが１０～５０ｍｍ程度であり、その切込み１３の長さ方向の間隔が１０～３０ｍｍ程度の破線状に形成される。 Further, the cut 13 is a cut that penetrates the front and back of the form panel 1 having a minute width and a predetermined length, and is formed so that liquid concrete or mortar does not leak from the cut 13 after the concrete or mortar is placed. ing. Moreover, the width | variety of the notch | incision 13 is formed so that the excess water | moisture content contained in the concrete or mortar can be discharged | emitted.
For example, the notches 13 are formed in a broken line shape having a width of about 0.3 to 1 mm and a length of about 10 to 50 mm, and a distance in the length direction of the notches 13 of about 10 to 30 mm.
　また、切込み１３列の幅方向の間隔は、実質的に凸条１１の幅方向の間隔、又は凸条１１の上面１８の幅方向の長さであるので、この凸条１１のパネル幅方向の形成間隔又は上面１８の幅を適宜調整することにより、切込み１３列の幅方向の間隔を１０～５０ｍｍ程度の任意な間隔に容易に調整することができる。
　このことにより、型枠パネル１の折り曲げ位置を所望の位置に自在に設計することが可能となり、型枠施工時の設計の自由度を大幅に向上させることが可能となる。
　さらに凸条１１を重ね合わせて幅方向に重ねて広げ、あるいは、長さ方向にずらすことによって、型枠パネル１を自由な大きさに広げて必要なサイズを実現することができる。 Further, since the interval in the width direction of the 13 rows of cuts is substantially the interval in the width direction of the ridges 11 or the length in the width direction of the upper surface 18 of the ridges 11, By appropriately adjusting the formation interval or the width of the upper surface 18, the interval in the width direction of the 13 rows of cuts can be easily adjusted to an arbitrary interval of about 10 to 50 mm.
As a result, it is possible to freely design the bending position of the formwork panel 1 to a desired position, and it is possible to greatly improve the degree of freedom of design at the time of formwork construction.
Further, by extending the ridges 11 by overlapping them in the width direction, or by shifting them in the length direction, the formwork panel 1 can be expanded to a desired size and the required size can be realized.
　また、凸条１１の上面１８側には、複数の押上げ片１４が設けられている。この押上げ片１４は、正方形の一辺を残して表裏に貫通した切込み２１と、その切込み２１を設けずに残した正方形の一辺である折返部２２とで形成され、この折返部２２に沿って押上げ片１４を折り返すことにより、押上げ片１４が開蓋状態になり、セパレータ挿入孔１５が形成される。本実施の形態では、押上げ片１４はすべて押し上げられて開蓋状態にある。
　前述したように、施工時には、型枠パネル１を押上げ片１４のある上面１８側を対向する型枠パネル１側に向けて立設させ、型枠を構成する。そうして、そのセパレータ挿入孔１５にセパレータ３３を挿入して締め金具（商品名：フォームタイ）３１で固定することにより、この対向した型枠パネル１同士を所定の間隔をおいて連結することができる。
　上面１８の幅方向の長さを１０～２０ｍｍ程度とすると、押上げ片１４の一辺の長さは５～１５ｍｍ程度である。 A plurality of push-up pieces 14 are provided on the upper surface 18 side of the ridge 11. The push-up piece 14 is formed by a notch 21 penetrating the front and back, leaving one side of the square, and a folded portion 22 that is one side of the square left without providing the notch 21, and along the folded portion 22. By folding back the push-up piece 14, the push-up piece 14 is in an open state, and a separator insertion hole 15 is formed. In the present embodiment, all the push-up pieces 14 are pushed up and are in the open state.
As described above, at the time of construction, the formwork panel 1 is erected with the upper surface 18 side with the push-up piece 14 facing the opposite formwork panel 1 side to constitute the formwork. Then, by inserting the separator 33 into the separator insertion hole 15 and fixing it with a fastener (product name: foam tie) 31, the opposing formwork panels 1 are connected at a predetermined interval. Can do.
If the length of the upper surface 18 in the width direction is about 10 to 20 mm, the length of one side of the push-up piece 14 is about 5 to 15 mm.
　ここで、この型枠パネル１を用いたコンクリート構造物の施工方法について説明する。
　図３に、本発明のコンクリート構造物としての壁面の施工時の構成を示す断面図である。
　図に示すように、１対の型枠パネル１を所定の間隔をおいて立設する。押上げ片１４を押し上げた後のセパレータ挿入孔１５を用いて、相互の型枠パネル１間にセパレータ３３を通してセパレータ座金３４で固定し、更に締め金具３１で２本の補強パイプ３２を抱えるようにしてナット等で位置決めし固定する。これによって、１対の型枠パネル１同士を相互に固定するとともに、対向する型枠パネル１間の間隔、すなわち壁厚を決めて保持することができる。 Here, the construction method of the concrete structure using this formwork panel 1 is demonstrated.
In FIG. 3, it is sectional drawing which shows the structure at the time of construction of the wall surface as a concrete structure of this invention.
As shown in the figure, a pair of formwork panels 1 are erected at a predetermined interval. Using the separator insertion hole 15 after the push-up piece 14 is pushed up, the separator 33 is fixed between the mold panels 1 with the separator washer 34, and the fastener 31 holds the two reinforcing pipes 32. Position and fix with a nut. Accordingly, the pair of formwork panels 1 can be fixed to each other, and the interval between the facing formwork panels 1, that is, the wall thickness can be determined and held.
　このとき、型枠パネル１の押上げ片１４がある側が、コンクリートを打設する側、すなわち対向する型枠パネル１側になるように両方の型枠パネル１を配置する。また、締め金具３１は、補強パイプ３２を水平方向に保持し、型枠パネル１の変形や型崩れを防止する役割を果たす。
　さらに、必要に応じてこの併設された型枠パネル１の上端に、型枠パネル１と同様な薄板金属で形成した断面コの字型のキャップを、その下端には断面コの字型のランナーなどの補助部材を装着するようにしても良い。 At this time, both the formwork panels 1 are arranged so that the side of the formwork panel 1 where the push-up piece 14 is located is the side where the concrete is placed, that is, the facing formwork panel 1 side. Further, the fastener 31 plays a role of holding the reinforcing pipe 32 in the horizontal direction and preventing deformation and deformation of the form panel 1.
Furthermore, if necessary, a U-shaped cross-sectional cap formed of a thin sheet metal similar to that of the mold panel 1 is provided at the upper end of the side-mounted formwork panel 1, and a U-shaped runner is provided at the lower end. You may make it mount | wear with auxiliary members, such as.
　このように、型枠パネル１が設置された後に、型枠パネル１で区画される空間内にコンクリートを打設し、養生させ、コンクリートを硬化した後、締め金具３１と補強パイプ３２とを取り外してコンクリート構造物である壁面を形成する。
　このように、型枠パネル１を埋め殺し状態で用いることにより、コンクリート躯体と型枠パネル１とが一体化され、構造物全体の数十％程度までの応力負担を型枠パネル１に負わせることが可能になり、せん断強度、曲げ強度、軸方向耐力、耐震強度を向上することができる。また、コンクリート躯体の硬化時に起きる収縮ひび割れを低減する効果がある。 In this way, after the formwork panel 1 is installed, concrete is placed in the space defined by the formwork panel 1 and cured, and after the concrete is hardened, the fastener 31 and the reinforcing pipe 32 are removed. To form a wall surface that is a concrete structure.
In this way, by using the formwork panel 1 in a buried state, the concrete frame and the formwork panel 1 are integrated, and a stress burden of up to about several tens of percent of the entire structure is imposed on the formwork panel 1. It is possible to improve shear strength, bending strength, axial strength and seismic strength. In addition, there is an effect of reducing shrinkage cracks that occur when the concrete frame is hardened.
　図４に、コンクリート構造物の施工に用いられる型枠パネル１の一例の平面図と断面図とを示す。
　この型枠パネル１の実施例では、押上げ片１４の一辺の長さが７．５ｍｍで、セパレータ挿入孔１５は７．５×７．５ｍｍの正方形であり、凸条１１の間隔が５０ｍｍであるのに合わせて、セパレータ挿入孔１５の相互間隔は、５０×５０ｍｍにしている。この孔の寸法はさほど大きなものではなく、開口率は２．３％に過ぎないので、コンクリートのノロの漏出がほとんど無いことが確認できた。一方、水分は充分に通過するので、コンクリートの養生、硬化時に水抜き穴としての効果を備え、コンクリート内の湿気を取り除くことが可能になる。また、型枠パネル１を形成する薄肉金属板の厚みは０．３～０．４ｍｍと薄く構成した。 In FIG. 4, the top view and sectional drawing of an example of the formwork panel 1 used for construction of a concrete structure are shown.
In this embodiment of the form panel 1, the length of one side of the push-up piece 14 is 7.5 mm, the separator insertion hole 15 is a 7.5 × 7.5 mm square, and the interval between the ridges 11 is 50 mm. In accordance with this, the interval between the separator insertion holes 15 is set to 50 × 50 mm. The size of the hole was not so large and the opening ratio was only 2.3%, so it was confirmed that there was almost no leakage of the concrete. On the other hand, since water passes sufficiently, it has an effect as a drain hole during curing and hardening of the concrete, and it is possible to remove moisture in the concrete. In addition, the thickness of the thin metal plate forming the formwork panel 1 was made as thin as 0.3 to 0.4 mm.
　次に、本発明に類似した参考例による対荷重変形の実測結果を示す。
　図５（ａ）および（ｂ）に比較例として用いた従来型の型枠工法によって作成した試験用コンクリート梁の構成を、図６に本発明に類似した工法によって作成した参考例の試験用コンクリート梁の構成を示す。
　いずれも、断面が１２０×２００ｍｍ、長さ２，０００ｍｍの梁であり、長さ方向に伸びる４本の１０ｍｍφの丸パイプを８０×１６０ｍｍに配置して軸にし、４ｍｍφの鉄筋をこの軸に巻きつけて配筋構成とした。そうして、この配筋構成を囲むように型枠を設けてコンクリートを打設し、養生させ、コンクリート硬化後、型枠を除いて試験用梁を構成した。 Next, an actual measurement result of anti-load deformation according to a reference example similar to the present invention is shown.
5 (a) and 5 (b) shows the configuration of a test concrete beam prepared by a conventional formwork method used as a comparative example, and FIG. 6 shows a test concrete of a reference example prepared by a method similar to the present invention. The structure of the beam is shown.
Each is a beam with a cross section of 120 x 200 mm and a length of 2,000 mm, and four 10 mmφ round pipes extending in the length direction are arranged at 80 x 160 mm as a shaft, and a 4 mmφ rebar is wound around this shaft. A bar arrangement was made. Then, a mold was provided so as to surround the bar arrangement, and concrete was cast and cured. After the concrete was cured, the test beam was configured by removing the mold.
　ここで、図５（ａ）に示す試験梁（従来例１）では、丸パイプに巻きつけた鉄筋の間隔を５０ｍｍに採り、図５（ｂ）に示す試験梁（従来例２）では、鉄筋の間隔を１００ｍｍに採っている。
　また、図６に示す参考例の試験梁では、図５（ｂ）に示す試験梁（従来例２）と同じく鉄筋の間隔を１００ｍｍに採った配筋構成に対して、図７に示すような、図１に示した本発明の型枠パネル１で押上げ片１４を設けない構成の型枠パネル２を埋め込み型枠として用い、さらに底面側に同じ型枠パネル２を底面のライナーとして用いてコンクリートを打設し、養生させて試験梁（参考例）を構成した。 Here, in the test beam (conventional example 1) shown in FIG. 5 (a), the interval between the reinforcing bars wound around the round pipe is 50 mm, and in the test beam (conventional example 2) shown in FIG. The interval is taken as 100 mm.
Further, in the test beam of the reference example shown in FIG. 6, as shown in FIG. 7, the arrangement of the reinforcing bars in which the interval between the reinforcing bars is 100 mm as in the test beam (conventional example 2) shown in FIG. 1 is used as an embedded mold, and the same mold panel 2 is used as a bottom liner on the bottom side. The mold panel 2 of the present invention shown in FIG. Concrete was cast and cured to form a test beam (reference example).
　この３例の試験梁に、図５及び６で矢印で示した位置に荷重Ｐ（ｋＮ）を加え、試験梁の底面側の変位量δ（ｍｍ）を計測した結果を図８に示す。
　図８の図表から分かるように、図５に示した従来型の試験梁（従来例１）では、変位５０ｍｍで、試験梁（従来例２）では変位３８ｍｍで、コンクリート躯体部分に亀裂が入った時点で梁としての構成が崩壊してしまっている。
　一方、参考例の試験梁では、埋め込み型枠パネル２の働きによって、コンクリート躯体部分に亀裂が入った後も変位７０ｍｍまで荷重応力に耐えて梁としての構成が維持される。
　これにより、この参考例は、例えば地震などに遭遇した際に構造物が完全に崩壊することを防ぐ耐性があることを示す。
　本発明の型枠パネル１を用いたコンクリート構造物では、さらに押上げ片１４がコンクリート内に固定される分、さらこの参考例よりも強度、耐力が増えるものと考えられる。 FIG. 8 shows the results of measuring the displacement δ (mm) on the bottom side of the test beam by applying a load P (kN) to the positions of the three test beams shown by arrows in FIGS. 5 and 6.
As can be seen from the chart of FIG. 8, the conventional test beam shown in FIG. 5 (conventional example 1) has a displacement of 50 mm, the test beam (conventional example 2) has a displacement of 38 mm, and the concrete frame portion has cracked. At that time, the structure as a beam has collapsed.
On the other hand, in the test beam of the reference example, the structure of the beam is maintained by withstanding the load stress up to a displacement of 70 mm even after the concrete frame portion is cracked by the action of the embedded form panel 2.
Thereby, this reference example shows that it has the tolerance which prevents that a structure collapses completely, for example, when encountering an earthquake etc.
In the concrete structure using the formwork panel 1 of the present invention, it is considered that the strength and proof stress are further increased as compared with this reference example because the push-up piece 14 is further fixed in the concrete.
　本発明は、以上に述べたように、比較的簡単な構成で、型枠パネルとコンクリート躯体との接合強度を高め、コンクリート構造物の面内剛性を向上し、せん断強度、曲げ強度、軸方向耐力、耐震強度を向上することができる。
　以上の説明では、コンクリート構造物として壁面について述べたが、柱、梁、床面などの構造物についても同様に施工することができるのはいうまでも無い。
　したがって、土木・建設の広範な分野で広く利用される可能性を有している。 As described above, the present invention has a relatively simple configuration, increases the bonding strength between the formwork panel and the concrete frame, improves the in-plane rigidity of the concrete structure, and provides shear strength, bending strength, and axial direction. Strength and seismic strength can be improved.
In the above description, the wall surface has been described as a concrete structure, but it goes without saying that structures such as columns, beams, and floor surfaces can be similarly constructed.
Therefore, it has the possibility of being widely used in a wide field of civil engineering and construction.
