Description

【0001】
【発明の属する技術分野】
本発明は、打ち込まれたコンクリートを成型する型枠に関し、特にその型枠パネルの支持装置に関するものである。
【0002】
【従来の技術】
従来は、図5〜図7に示すようになっていた。図5〜図7において、1は型枠パネル11を内面側から支持する円錐台状のホルダ(木コン)、5は該型枠パネル11を外面側から支持する棒状のホームタイである。上記ホルダ1は、プラスチック製の主体2の軸心部に金属製の連結軸4を貫通させて一体的に固着してなる。即ち、主体2は円錐台状に形成するとともに、大径側の内周部に凹部3を形成する。また、連結軸4はその左端部を上記主体2の大径側から左方に突出させてこの部に雄ねじ部4aを形成し、右端部は上記主体2の小径側内に埋設し、その軸心部にねじ孔4bを形成する。また、連結軸4の上記凹部3内に位置する基部は大径かつ六角形状の工具係合部4cに形成する。
【0003】
上記ホームタイ5は、金属材により左右に細長く形成し、図5、図7に示すように、右端部に上記雄ねじ部4aが螺合するねじ孔5aを形成するとともに、該右端に大径のフランジ部5bを形成する。また、左端部に楔係合用の長孔5c(図7)を形成する。
【0004】
図6,図7は上記ホルダ1及びホームタイ5の実施形態を示す。図6において、10はコンクリート製の基礎、あるいは壁等の躯体を形成する型枠であり、一対の型枠パネル11,11を左右に対面させ、これらを金属棒製のセパレーター12、前述したホルダ1及びホームタイ5等を使用して所定の間隔に保持する。即ち、ホルダ1の雌ねじ部4bを上記セパレーター12の両端部に形成したねじ軸12aにねじ込み固定し、これらを左右の型枠パネル11間に介在させるとともに、各ホルダ1の大径側から突出した雄ねじ部4aを上記各型枠パネル11に形成した通し孔11a(図7)に内面側から挿通し、その端部を各型枠パネル11から外側に突出させる。
【0005】
次いで、ホームタイ5を各型枠パネル11の外側に配置し、そのねじ孔5aを上記ホルダ1の雄ねじ部4aの外端部にねじ込み、そのフランジ部5bとホルダ1の大径側の端面とで上記各型枠パネル11を挟持し、次いで、上記ホームタイ5の外端部に形成した長孔5cに楔6を打込み、各型枠パネル11の外面側に取り付けた補強用の横管13、たて桟14を介して各型枠パネル11の外面を補強し、図6に示すような型枠10を形成する。この状態で各型枠パネル11間に生コンクリートを充填、硬化させてコンクリート躯体15を形成する。
【0006】
上記型枠10をコンクリート躯体15から離型する際には、図7に示すように、楔6をホームタイ5の長孔5bから取り外し、又は緩め、該楔6または工具を使用して上記ホームタイ5を緩み方向に回転させ、これをホルダ1の雄ねじ部4aから取り外した後、横管13を型枠パネル11から取り外す(図7の左部の状態)。次いで型枠パネル11をコンクリート躯体15に対して平行に保ちつつ、外側に移動させ、該コンクリート躯体15及びホルダ1の雄ねじ部4aから外す図7の右部の状態)。次いで、ホルダ1の工具係合部4cにスパナ等の工具を係合させ、これを緩み方向に回転させてセパレーター12のねじ軸12a、従ってコンクリート躯体15から外した後、該ホルダ1の離脱によって発生したコンクリート躯体15の凹部にモルタルを詰めてこの部を平滑にする。
【0007】
【発明が解決しようとする課題】
上記従来のものは、ホルダ1の大径側に雄ねじ部4aが突出していたので、型枠パネル11をコンクリート躯体15から取り外す際に、該型枠パネル11をコンクリート躯体15に対して平行に保ちつつ、外側に移動させる必要があり、これの離型作業に手数を要するとともに、該離型時に型枠パネル11の通し孔11aが雄ねじ部4aによって損傷され易くなるものであった。本発明は、ホルダの軸心部にねじ孔を貫通形成し、ホームタイ側にホルダのねじ孔と螺合する雄ねじ部を設けることにより、上記不具合を解消した新規な型枠パネルの支持装置を得ることを目的とする。
【0008】
【課題を解決するための手段】
本発明は、上記目的を達成するために以下の如く構成したものである。即ち、軸心部にねじ孔が貫通形成された円錐台状のホルダを設け、該ホルダを、その大径側にて相対する各型枠パネルの内面に対面させ、各型枠パネル間に介装したセパレーターの両端部を前記各ホルダの小径側のねじ孔に螺合させ、一端部に大径のフランジ部及び該フランジ部の軸心部から軸方向に突出する雄ねじ部を有するホームタイを設け、該ホームタイの雄ねじ部を前記各型枠パネルの外側から挿通して前記各ホルダの大径側のねじ孔に螺合させるとともに、前記フランジ部を各型枠パネルの外面に当接させる構成にしたものである。

【0013】
次いで、ホームタイ25を各型枠パネル11の外側に配置し、その雄ねじ部25aを外側から上記各型枠パネル11の通し孔11aに挿通し、その端部を上記ホルダ20の大径側のねじ孔23aにねじ込み、各型枠パネル11を上記ホームタイ25のフランジ部25bとホルダ20の大径側の端面とで挟持する。次いで、上記ホームタイ25の外端部に形成した長孔25cに楔26を打込み、各型枠パネル11の外面側に取り付けた補強用の横管13、たて桟14を介して各型枠パネル11の外面を補強し、図2に示すような型枠10を形成する。この状態で各型枠パネル11間に生コンクリートを充填し、これを硬化させてコンクリート躯体15を形成する。
【0014】
上記型枠10をコンクリート躯体15から離型する際には、図3に示すように、楔26をホームタイ25の長孔25cから取り外し、又は緩め、該楔26または工具を使用して上記ホームタイ25を緩み方向に回転させ、これをホルダ20のねじ孔23aから取り外した後、横管13を型枠パネル11から取り外す。次いで、図4に示すように、型枠パネル11をコンクリート躯体15から外す。この場合、ホルダ20の外側の端面はコンクリート躯体15と同一面となっているため、上記型枠パネル11は、コンクリート躯体15の面に対して傾斜させながら外すことができ、型枠パネル11とコンクリート躯体15間にバール等を差し込んで容易に外すことができる。
【0015】
次いで、ホルダ20の工具係合部23bにスパナ等の工具を係合させ、これを緩み方向に回転させてセパレーター12のねじ軸12a、従ってコンクリート躯体15から外す。その後、上記ホルダ20の離脱によって発生したコンクリート躯体15の凹部にモルタルを詰めてこの部を平滑にする。
【0016】
【発明の効果】
以上の説明から明らかな如く、本願に係る発明は、ホルダの軸心部にねじ孔を貫通形成し、ホームタイの端部に雄ねじ部を形成し、この雄ねじ部を型枠パネルの外側から上記ホルダの大径側のねじ孔に螺合させるようにしたので、型枠パネルをコンクリート躯体から取り外す際に、上記ホルダにコンクリート躯体の面から外側方に突出する突起物が存在しなくなり、各型枠パネルをコンクリート躯体から容易かつ迅速に取り外すことができる。
