【考案の詳細な説明】
この考案はコンクリート構造物の型枠工事に使
用するコンクリート型枠締付金具に関する。[Detailed Description of the Invention] This invention relates to a concrete formwork fastening fitting used in formwork work for concrete structures.
従来、型枠工事に当つて予め、当金を締付杆本
体に組込んだこの種型枠締付金具には、第６図に
示すように外側に雄ねじａを設けた締付杆本体Ａ
に当金Ｂ及び締付ナツトＣを一体的に組込んだも
のであるため、型枠内にコンクリートを打込む
時、雄ねじの表面にコンクリートが付着すること
が多い。 Conventionally, this type of formwork clamping fitting, in which a stopper is assembled into the clamping rod body in advance during formwork work, has a clamping rod body A with a male thread a provided on the outside, as shown in Fig. 6.
Since the bolt B and the tightening nut C are integrated into the mold, concrete often adheres to the surface of the male thread when pouring concrete into the formwork.
このため型枠解体に当つてねじ操作が困難で外
れないことが多々あり、さらに再使用に当つて補
修を要する等、実用上大変不便であつた。 For this reason, when dismantling the formwork, it was often difficult to operate the screws and they did not come off, and furthermore, repairs were required before reuse, which was very inconvenient in practice.
この考案は上記の欠点に鑑みなされたもので、
コンクリート型枠の組立、解体に当つて再使用を
可能にし、合理的で実用価値の高いコンクリート
型枠締付金具を提供することを目的とするもので
ある。 This idea was made in view of the above drawbacks,
The purpose of the present invention is to provide a concrete formwork fastening fitting that is rational and of high practical value and that enables reuse when assembling and dismantling concrete formwork.
次にその構成を第１実施例を示す第１図と共に
説明すると、１はセパレーターＳと連結する型枠
締付杆で、基端部の軸心に沿つて雌ねじ２を、後
方外周に雄ねじ３を、それぞれ設けてある。 Next, the structure will be explained with reference to FIG. 1 showing the first embodiment. 1 is a formwork tightening rod connected to the separator S, which has a female thread 2 along the axis of the base end and a male thread 3 on the rear outer periphery. are provided for each.
４はバタ押え金（この例では単管パイプに適合
した形態とした）で、前記型枠締付杆１の後方が
自由に挿通するための通孔５を設けてある。 Reference numeral 4 denotes a butterfly presser foot (in this example, it has a shape suitable for a single pipe), and is provided with a through hole 5 through which the rear of the formwork clamping rod 1 can be inserted freely.
６は締付ナツトで、貫通した雌ねじ６ａを有す
る筒状体７の一端に膨出係合部８（通常六角形状
が望しいが、スパナ掛けのできる形状であれば他
の方法でもよい）を設けてある。 Reference numeral 6 denotes a tightening nut, and a bulging engagement portion 8 (normally hexagonal shape is desirable, but any other shape is acceptable as long as it can be attached with a wrench) is attached to one end of a cylindrical body 7 having a female thread 6a extending therethrough. It is provided.
次に上記構造のこの考案は、第２図に示すよう
に型枠Ｐに挿通したセパレーターＳに型枠締付杆
１の基端側を螺入して取付け、さらに型枠Ｐ外側
に縦バタＢ及び横バタB′をそれぞれ配する。 Next, in this invention of the above structure, as shown in Fig. 2, the proximal end of the formwork clamping rod 1 is screwed into the separator S inserted into the formwork P, and the vertical bar is attached to the outside of the formwork P. B and horizontal butterfly B' are arranged respectively.
続いてバタ押え金４を横バタB′に押当て、締
付ナツト６をその筒状体７の他端側からバタ押え
金４の通孔５を通して型枠締付杆１の雄ねじ３に
螺入して締付けるものである。 Next, press the butterfly foot 4 against the horizontal butterfly B', and screw the tightening nut 6 from the other end of the cylindrical body 7 into the male thread 3 of the formwork clamping rod 1 through the through hole 5 of the butterfly foot 4. It is inserted and tightened.
また、横バタB′のみを配して型枠を締付ける
場合には、第３図に示すように、横バタB′に押
付けたバタ押え金４に対し、締付ナツト６をその
膨出係合部側から型枠締付杆１の雄ねじ３に螺入
して締付けるものである。 In addition, when tightening the formwork with only the horizontal flap B', as shown in Fig. 3, the tightening nut 6 is pressed against the flap presser foot 4 pressed against the horizontal flap B' by its bulging part. It is screwed into the male screw 3 of the formwork clamping rod 1 from the joint side and tightened.
このため型枠締付杆１の雄ねじ３は締付ナツト
６によつて保護されているので、コンクリート打
設時のコンクリートが付着しない。 Therefore, since the male thread 3 of the formwork clamping rod 1 is protected by the clamping nut 6, concrete does not adhere to it during concrete pouring.
従つて再使用が可能である。 Therefore, reuse is possible.
また施工中や取扱い中にねじ部が損傷すること
もない。 Further, the threaded portion will not be damaged during construction or handling.
さらに締付ナツトのねじ込み方向を変更するこ
とによつて縦バタ及び横バタを配して締付ける場
合と、横バタあるいは縦バタのみを配して締付け
る場合とに兼用できるから実用的価値の高いもの
である。 Furthermore, by changing the screwing direction of the tightening nut, it can be used both for tightening with vertical and horizontal flaps and for tightening with only horizontal or vertical flaps, so it has high practical value. It is.
この考案の第２実施例としては第４図に示すよ
うに、締付ナツト２６の他端側外周に別の係合部
７ａを設けることにより、第３図のような使用状
態に当つて後端からスパナ掛けとして利用できる
効果がある。 As a second embodiment of this invention, as shown in FIG. 4, another engaging portion 7a is provided on the outer periphery of the other end of the tightening nut 26, so that the tightening nut 26 can be used after the use as shown in FIG. It has the effect of being used as a wrench from the end.
また、第３実施例としては第５図に示すように
締付ナツト３６の他端部端面に凹状の別の係合部
７ａを設けることもできる。 Further, as a third embodiment, as shown in FIG. 5, another concave engaging portion 7a may be provided on the other end surface of the tightening nut 36.
