【発明の詳細な説明】
この発明は鉄筋コンクリート構造の塔状構造物のコンク
リート打設に際して適用される型枠工法に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a formwork method that is applied when concrete is poured into a tower-like structure having a reinforced concrete structure.
従来前記した塔状構造物の施工に際してはスライディン
グフォーム工法あるいはジャンプフオーム工法が実施さ
れている。Conventionally, when constructing the tower-like structure described above, a sliding form construction method or a jump form construction method has been implemented.
ところでスライディングフォーム工法は施工管理が問題
であり壁面に窓その他突出部のある場合は施工が問題で
ある。However, with the sliding form construction method, construction management is a problem, and if there are windows or other protruding parts on the wall, construction becomes a problem.
またジャンプフオーム工法は型枠を２〜３セツト用意し
、−股下の型枠を上方へ転用しこれを繰返して上昇し、
足場は型枠に取りつけられているので、型枠転用の際足
場盛り替え作業が供なう問題がある。In addition, in the jump form construction method, two to three sets of formwork are prepared, and the formwork at the bottom is diverted upward and this is repeated to ascend.
Since the scaffolding is attached to the formwork, there is a problem in that the scaffolding must be replaced when the formwork is repurposed.

また門型ヨーク３の縦枠上部内側に突設したアングル９
と最上部の端太材５との間に型枠吊ボルト１０を配して
脱型して引揚げる際に門型ヨーク３から型枠４，４を懸
垂しうるように構成しである。In addition, an angle 9 protruding from the inside of the upper part of the vertical frame of the gate-shaped yoke 3
Formwork suspension bolts 10 are disposed between the uppermost end thick material 5 and the formworks 4, 4 can be suspended from the gate-shaped yoke 3 when demolding and lifting.
この門型ヨーク３の外側にはブラケット１１を突設して
足場１２を載置しである。A bracket 11 is provided protruding from the outside of this gate-shaped yoke 3, and a scaffold 12 is placed thereon.
この装置は２重壁の筒状塔を施工する場合の実施例を示
しており、同様の型枠装置が足場１３を介して連結して
あり、中心部にも足場１４を設けである。This apparatus shows an embodiment for constructing a double-walled cylindrical tower, in which a similar formwork apparatus is connected via a scaffold 13, and a scaffold 14 is also provided in the center.
また各足場から吊足場１５を吊してある。Furthermore, a suspended scaffold 15 is suspended from each scaffold.
施工に際し、図示した状態のように相対する型枠４，４

で型枠４，４間にコンクリートを打設し、そのコンクリ
ートが所要強度に硬化した後型枠４，４をキャンバ−７
を外すことにより型枠４，４を側方に開いて脱型する。During construction, formwork 4, 4 facing each other as shown in the figure
is installed by fixing its lower part with a formwork clamping fitting 6 buried in the concrete that has been poured first, and supporting its upper part with a gate-shaped yoke 3 via a camber 7, and then attaching the formwork 4 , 4, and after the concrete has hardened to the required strength, the formworks 4 and 4 are placed on the camber 7.
By removing the molds 4, 4, the molds are opened laterally and removed.
脱型した型枠４，４は吊ボルト１０により懸垂される。The demolded formworks 4, 4 are suspended by hanging bolts 10.
そこでスライドジヤツキ２を操作して門型ヨーク３をロ
ッド１に沿って上昇させ、前記と同様の方法により型枠
を設置し、同様の工程を繰返す。Then, the slide jack 2 is operated to raise the gate-shaped yoke 3 along the rod 1, the formwork is installed in the same manner as described above, and the same process is repeated.
なお型枠４の高さは２ｍ前後とし、またコンクリート中
には適宜鉄筋が配筋しである。The height of the formwork 4 is approximately 2 m, and reinforcing bars are appropriately placed in the concrete.
この発明は以上の構成からなり、単一の型枠がヨークか

法、ジャツプフォーム工法の何れの欲点をも解消しえて
実用上きわめて有用である。This invention has the above-mentioned structure, and since a single formwork can be suspended from the yoke, it can be replaced as the yoke rises, and the formwork can be easily set and dismantled, making it easy to carry out construction work. It is easy to manage, and it is extremely useful in practice since it overcomes the disadvantages of both the sliding form construction method and the jap form construction method.
