Description

本考案は、例えば、コンクリート用型枠の組み立て・解体に使用可能な型枠用工具に関する。 The present invention relates to, for example, a formwork tool that can be used for assembling and disassembling a concrete formwork.

例えば、コンクリート用型枠の組み立てにおいては、型枠板の内面から外面へとＰコンのボルト（ネジ軸部）を貫通させつつ型枠板の内面に対してＰコンを固定するとともに、型枠板の内面側において対向する一対のＰコンをセパレータで互いに連結し、さらに、型枠緊結部材のネジ穴（タイロッドの基端部）をＰコンのボルトに螺合させることで型枠緊結部材がＰコンと締結された状態で型枠板の外面に組み付けられる（例えば、特許文献１の図５参照）。このような型枠板に対するＰコンの固定や型枠緊結部材の組み付けは、各々に適した専用ソケットなどの型枠用工具に交換した上で電動ドライバを用いて作業が行われる。 For example, when assembling a concrete formwork, the P-con is fixed to the inner surface of the formwork while penetrating the P-con bolt (screw shaft) from the inner surface to the outer surface of the formwork, and the formwork is used. A pair of P-cons facing each other on the inner surface side of the plate are connected to each other with a separator, and the screw holes (base end of the tie rod) of the formwork binding member are screwed into the bolts of the P-con to form the formwork binding member. It is assembled to the outer surface of the mold plate in a state of being fastened to the P-con (see, for example, FIG. 5 of Patent Document 1). Fixing the P-con to the formwork plate and assembling the formwork binding member is performed by using an electric screwdriver after exchanging with a formwork tool such as a dedicated socket suitable for each.

以下、本考案の一実施形態を図面に基づいて説明する。以下の説明において、同一又は類似の構成には同一の符号を付し、その説明を省略又は簡略化する。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, the same or similar configurations are designated by the same reference numerals, and the description thereof will be omitted or simplified.

図１は、本考案の一実施形態に係る型枠用工具１の適用例を示す斜視図、図２は、型枠用工具１の外観全体を示す斜視図、図３は、型枠用工具１の縦断面を示す断面図、図４は、型枠用工具１の底部を示す底面図である。図１に示すように、本実施形態の型枠用工具１は、電動ドライバ本体２に対して取り替え可能に取り付けられるソケットビットであり、例えば、コンクリート用型枠の組み立て・解体に際して好適に用いられるものである。具体的にいうと、型枠用工具１は、図５〜８を参照して後述するように、型枠パネルＰに対してＰコンＣの固定又は取り外しとともに型枠緊結部材（例えば、フォームタイ（登録商標））Ｆの組み付け又は取り外しにも兼用可能なものである。なお、型枠用工具１は、電動ドライバ本体２に取り付けられた状態で時計回り・時計逆回りのいずれか一方向に回転させられるが、以下の図示説明においては、電動ドライバ本体２を図示略しつつも当該電動ドライバ本体２によって型枠用工具１が回転させられるものとして説明する。 FIG. 1 is a perspective view showing an application example of the formwork tool 1 according to the embodiment of the present invention, FIG. 2 is a perspective view showing the entire appearance of the formwork tool 1, and FIG. 3 is a formwork tool. FIG. 4 is a cross-sectional view showing a vertical cross section of No. 1, and FIG. 4 is a bottom view showing a bottom portion of the formwork tool 1. As shown in FIG. 1, the formwork tool 1 of the present embodiment is a socket bit that is replaceably attached to the electric screwdriver main body 2, and is suitably used, for example, when assembling and disassembling a concrete formwork. It is a thing. Specifically, as will be described later with reference to FIGS. 5 to 8, the formwork tool 1 fixes or removes the P-con C to the formwork panel P and a formwork binding member (for example, a foam tie). (Registered trademark)) It can also be used for assembling or removing F. The formwork tool 1 can be rotated in either clockwise or counterclockwise direction while being attached to the electric screwdriver main body 2. However, in the following illustration, the electric screwdriver main body 2 is not shown. However, it is assumed that the formwork tool 1 is rotated by the electric screwdriver main body 2.

図２〜４に示すように、型枠用工具１は、円錐台状のソケット部１０と、電動ドライバ本体２のチャック部に対して着脱可能に装着される六角軸２０とを備える。六角軸２０は、ソケット部１０の台頭部に突設している。 As shown in FIGS. 2 to 4, the formwork tool 1 includes a truncated cone-shaped socket portion 10 and a hexagonal shaft 20 that is detachably attached to the chuck portion of the electric driver main body 2. The hexagonal shaft 20 projects from the pedestal of the socket portion 10.

ソケット部１０は、後述するＰコン本体Ｃ１の外周面（図５参照）に沿うように形成された円錐状の嵌合凹部１１と、後述する型枠緊結部材ＦのタイロッドＦ１の先端部Ｆ１ａ（図５参照）を回転可能に嵌合凹部１１の奥方の底部に形成された溝穴１２とを有する。 The socket portion 10 includes a conical fitting recess 11 formed along the outer peripheral surface (see FIG. 5) of the P-con main body C1 described later, and a tip portion F1a of the tie rod F1 of the formwork binding member F described later. (See FIG. 5) is rotatably provided with a groove hole 12 formed at the inner bottom of the fitting recess 11.

嵌合凹部１１は、周方向に沿って等ピッチ（例えば、六角ボルトや六角ナットの外形と係合可能なピッチ）で交互に複数の凸部１１ａと凹部１１ｂとが形成されている。複数の凸部１１ａは、Ｐコン本体Ｃ１の外周面に対して概ね線接触するように形成されている。複数の凹部１１ｂは、基本的にＰコン本体Ｃ１の外周面に接触しない。これらの凸部１１ａ及び凹部１１ｂは、好ましくは各々１２個ずつ形成されている。 In the fitting recess 11, a plurality of convex portions 11a and recesses 11b are alternately formed at equal pitches (for example, a pitch that can be engaged with the outer shape of a hexagon bolt or a hexagon nut) along the circumferential direction. The plurality of convex portions 11a are formed so as to be substantially in line contact with the outer peripheral surface of the P-con main body C1. The plurality of recesses 11b basically do not come into contact with the outer peripheral surface of the P-con main body C1. Twelve convex portions 11a and 12 concave portions 11b are preferably formed.

図５に示すように、Ｐコン本体Ｃ１の外形寸法として、例えば、底部外径ｄ１を３０ｍｍ、頭部外径ｄ２を２４ｍｍ、高さｈを２５ｍｍとした場合、ソケット部１０の概ね外形寸法は、底部の外径Ｄ０が３０ｍｍ、高さＨ０が４０ｍｍとされ、嵌合凹部１１の概ね寸法は、ソケット部１０の底部開口面に沿う最大内径Ｄ１が２６ｍｍ、嵌合凹部１１の底部に沿う最小内径Ｄ２が２１ｍｍ、ソケット部１０の底部開口面から嵌合凹部１１の底部までの深さＨ１が２０ｍｍとされる。このような嵌合凹部１１は、型枠パネルＰの内面から外面へとＰコンＣのネジ軸部Ｃ２を貫通させつつ型枠パネルＰの内面に対してＰコン本体Ｃ１を固定する際に用いられる。 As shown in FIG. 5, when the external dimensions of the P-con main body C1 are, for example, the bottom outer diameter d1 is 30 mm, the head outer diameter d2 is 24 mm, and the height h is 25 mm, the approximate external dimensions of the socket portion 10 are The outer diameter D0 of the bottom portion is 30 mm, the height H0 is 40 mm, and the approximate dimensions of the fitting recess 11 are that the maximum inner diameter D1 along the bottom opening surface of the socket portion 10 is 26 mm and the minimum fitting recess 11 is along the bottom. The inner diameter D2 is 21 mm, and the depth H1 from the opening surface at the bottom of the socket portion 10 to the bottom of the fitting recess 11 is 20 mm. Such a fitting recess 11 is used when fixing the P-con main body C1 to the inner surface of the form panel P while penetrating the screw shaft portion C2 of the P-con C from the inner surface to the outer surface of the form panel P. Be done.

溝穴１２は、嵌合凹部１１の底部を正面から見て一対の長矩形が交差するように十字状に形成されている。溝穴１２は、型枠緊結部材ＦのタイロッドＦ１の先端部Ｆ１ａを軸方向に挿嵌可能とするように形成されている。 The groove hole 12 is formed in a cross shape so that a pair of oblong rectangles intersect when the bottom of the fitting recess 11 is viewed from the front. The groove hole 12 is formed so that the tip end portion F1a of the tie rod F1 of the formwork binding member F can be inserted in the axial direction.

溝穴１２の概ね寸法は、長手方向の長さＬが１６ｍｍ、短手方向の幅Ｗが９ｍｍ、嵌合凹部１１の底部から六角軸２０の方へと向かう深さＨ２が１０ｍｍとされる。このような溝穴１２は、型枠パネルＰの外面側において型枠緊結部材ＦのタイロッドＦ１の基端部Ｆ１ｂをＰコンＣのネジ軸部Ｃ２に螺合させつつ型枠パネルＰの外面に対して型枠緊結部材Ｆを組み付ける際に用いられる。 The general dimensions of the groove hole 12 are such that the length L in the longitudinal direction is 16 mm, the width W in the lateral direction is 9 mm, and the depth H2 from the bottom of the fitting recess 11 toward the hexagonal shaft 20 is 10 mm. Such a groove hole 12 is formed on the outer surface of the form panel P while screwing the base end portion F1b of the tie rod F1 of the form binding member F to the screw shaft portion C2 of the P-con C on the outer surface side of the form panel P. On the other hand, it is used when assembling the formwork binding member F.

次に、型枠用工具１の使用方法について、図面を参照して説明する。図５は、型枠組み立て時においてＰコンＣを型枠パネルＰの内面に固定する際の型枠用工具１の使用例を示す断面図、図６は、その際の型枠用工具１の底面図、図７は、型枠組み立て時において型枠パネルＰの外面に型枠緊結部材Ｆを組み付ける際の型枠用工具１の使用例を示す断面図、図８は、その際の型枠用工具１の底面図、図９は、型枠組み立て時とは別の型枠用工具１の別途使用例を示す底面図である。 Next, how to use the formwork tool 1 will be described with reference to the drawings. FIG. 5 is a cross-sectional view showing an example of using the formwork tool 1 when fixing the P-con C to the inner surface of the formwork panel P at the time of assembling the formwork, and FIG. 6 is a cross-sectional view of the formwork tool 1 at that time. The bottom view and FIG. 7 are cross-sectional views showing an example of using the formwork tool 1 when assembling the formwork binding member F to the outer surface of the formwork panel P at the time of assembling the formwork, and FIG. 8 shows the formwork at that time. The bottom view and FIG. 9 of the tool 1 are bottom views showing a separate usage example of the formwork tool 1 different from that at the time of assembling the formwork.

図５及び図６に示すように、型枠組み立て時においては、型枠用工具１を用いてＰコンＣを型枠パネルＰの内面に固定する。その際、型枠パネルＰの内面から外面へとＰコンＣのネジ軸部Ｃ２を貫通させつつ、型枠パネルＰの内面側においてＰコン本体Ｃ１にソケット部１０の嵌合凹部１１を嵌め合わせた状態とし、図示しない電動ドライバ本体２をスイッチ操作することでソケット部１０を六角軸２０の軸回り所定方向に回転させる。 As shown in FIGS. 5 and 6, when assembling the formwork, the formwork tool 1 is used to fix the P-con C to the inner surface of the formwork panel P. At that time, the fitting recess 11 of the socket portion 10 is fitted to the P-con main body C1 on the inner surface side of the form panel P while penetrating the screw shaft portion C2 of the P-con C from the inner surface to the outer surface of the form panel P. The socket portion 10 is rotated in a predetermined direction around the hexagonal shaft 20 by operating a switch on the electric driver main body 2 (not shown).

このとき、Ｐコン本体Ｃ１の底部外径ｄ１（３０ｍｍ）よりもソケット部１０の底部開口面に沿う嵌合凹部１１の最大内径Ｄ１（２６ｍｍ）の方が小さいため、Ｐコン本体Ｃ１の底部は、ソケット部１０の底部開口面よりも外方に露出している。また、Ｐコン本体Ｃ１の外周面は、嵌合凹部１１の複数の凸部１１ａに概ね線接触することにより、Ｐコン本体Ｃ１は、嵌合凹部１１に咬み合った状態で保持される。これにより、Ｐコン本体Ｃ１の底部が型枠パネルＰの内面に接触するまでソケット部１０が型枠パネルＰに接することなく確実に回転させられ、そうして最終的には、Ｐコン本体Ｃ１の底部が型枠パネルＰの内面に接触した状態でＰコンＣが型枠パネルＰに対して固定される。また、図示しない電動ドライバ本体２のスイッチ操作により、型枠用工具１を逆回転させることで、ＰコンＣを取り外すことができる。 At this time, since the maximum inner diameter D1 (26 mm) of the fitting recess 11 along the bottom opening surface of the socket portion 10 is smaller than the bottom outer diameter d1 (30 mm) of the P-con main body C1, the bottom of the P-con main body C1 is , It is exposed to the outside from the bottom opening surface of the socket portion 10. Further, the outer peripheral surface of the P-con main body C1 is substantially in line contact with the plurality of convex portions 11a of the fitting recess 11, so that the P-con main body C1 is held in a state of being engaged with the fitting recess 11. As a result, the socket portion 10 is reliably rotated without contacting the mold panel P until the bottom portion of the P-con main body C1 contacts the inner surface of the form panel P, and finally, the P-con main body C1 The P-con C is fixed to the mold panel P in a state where the bottom portion of the mold is in contact with the inner surface of the mold panel P. Further, the P-con C can be removed by rotating the mold tool 1 in the reverse direction by operating a switch of the electric screwdriver main body 2 (not shown).

次に、図７及び図８に示すように、型枠パネルＰの外面に突出したＰコンＣのネジ軸部Ｃ２に対して型枠緊結部材ＦのタイロッドＦ１の基端部Ｆ１ｂを螺合させることにより、型枠パネルＰの外面に型枠緊結部材Ｆを仮組として組み付ける。型枠緊結部材Ｆは、タイロッドＦ１に管押え部材Ｆ２及びナットＦ３が仮組された状態にある。タイロッドＦ１の先端部Ｆ１ａは、押圧加工などによって軸方向断面が長矩形状に形成されている。タイロッドＦ１の先端部Ｆ１ａから中央部にかけては、ナットＦ３に螺合する雄ネジが形成されている。タイロッドＦ１の基端部Ｆ１ｂには、ＰコンＣのネジ軸部Ｃ２に螺合する雌ネジが形成されている。 Next, as shown in FIGS. 7 and 8, the base end portion F1b of the tie rod F1 of the form binding member F is screwed into the screw shaft portion C2 of the P-con C protruding from the outer surface of the form panel P. As a result, the formwork binding member F is temporarily assembled on the outer surface of the formwork panel P. The formwork binding member F is in a state in which the pipe holding member F2 and the nut F3 are temporarily assembled to the tie rod F1. The tip portion F1a of the tie rod F1 has an elongated cross section in the axial direction formed by pressing or the like. A male screw screwed into the nut F3 is formed from the tip portion F1a to the center portion of the tie rod F1. A female screw screwed into the screw shaft portion C2 of the P-con C is formed on the base end portion F1b of the tie rod F1.

ＰコンＣのネジ軸部Ｃ２に対して型枠緊結部材ＦのタイロッドＦ１の基端部Ｆ１ｂを螺合させる際には、型枠パネルＰの内面側においてＰコン本体Ｃ１に型枠用工具１の嵌合凹部１１を嵌め合わせてＰコン本体Ｃ１を固定した状態とする一方、型枠パネルＰの外面側において別の型枠用工具１を用いて、この別の型枠用工具１の溝穴１２にタイロッドＦ１の先端部Ｆ１ａを嵌め合わせた状態とし、図示しない電動ドライバ本体２をスイッチ操作することで当該型枠用工具１のソケット部１０を六角軸２０の軸回り所定方向に回転させる。これにより、タイロッドＦ１の基端部Ｆ１ｂがＰコンＣのネジ軸部Ｃ２と螺合しつつ締結され、型枠緊結部材ＦがＰコンＣと連結された状態で型枠パネルＰの外面に仮組される。 When screwing the base end portion F1b of the tie rod F1 of the formwork binding member F to the screw shaft portion C2 of the formwork C, the formwork tool 1 is attached to the formwork body C1 on the inner surface side of the formwork panel P. While the fitting recess 11 of the above is fitted to fix the P-con main body C1, another formwork tool 1 is used on the outer surface side of the formwork panel P to form a groove of the other formwork tool 1. With the tip F1a of the tie rod F1 fitted in the hole 12, the socket portion 10 of the formwork tool 1 is rotated in a predetermined direction around the hexagonal shaft 20 by operating a switch on the electric driver body 2 (not shown). .. As a result, the base end portion F1b of the tie rod F1 is fastened while being screwed to the screw shaft portion C2 of the P-con C, and the formwork binding member F is temporarily attached to the outer surface of the formwork panel P in a state of being connected to the P-con C. To be assembled.

このとき、Ｐコン本体Ｃ１が嵌合凹部１１に咬み合った状態で回転不能に保持されているため、型枠緊結部材ＦのタイロッドＦ１は、回転しないＰコンＣのネジ軸部Ｃ２に対して別の型枠用工具１を用いて確実に回転させられ、型枠緊結部材ＦがＰコンＣに対して強固に締結される。また、溝穴１２は、十字状に形成されているため、タイロッドＦ１に対して型枠用工具１を軸回りいずれかの方向に概ね最大４５度程度回すだけで溝穴１２に対してタイロッドＦ１の先端部Ｆ１ａを容易に嵌め合わせることができる。なお、特に図示しないが、このようにしてＰコンＣと型枠緊結部材Ｆとが締結された後、型枠パネルＰの内面側において互いに対向する一対のＰコンＣをセパレータで互いに連結するとともに、型枠パネルＰの外面に仮組された型枠緊結部材Ｆを介して単管パイプが保持される。また、図示しない電動ドライバ本体２のスイッチ操作により、型枠用工具１を逆回転させることで、型枠緊結部材Ｆを取り外すことができる。 At this time, since the P-con main body C1 is held in a non-rotatable state in a state of being engaged with the fitting recess 11, the tie rod F1 of the formwork binding member F with respect to the screw shaft portion C2 of the non-rotating P-con C. It is reliably rotated by using another formwork tool 1, and the formwork binding member F is firmly fastened to the P-con C. Further, since the groove hole 12 is formed in a cross shape, the tie rod F1 with respect to the groove hole 12 can be obtained by simply turning the mold tool 1 about 45 degrees in any direction around the axis with respect to the tie rod F1. The tip portion F1a of the above can be easily fitted. Although not particularly shown, after the P-con C and the form-binding member F are fastened in this way, a pair of P-con Cs facing each other on the inner surface side of the form panel P are connected to each other with a separator. , The single pipe is held via the formwork binding member F temporarily assembled on the outer surface of the formwork panel P. Further, the formwork binding member F can be removed by rotating the formwork tool 1 in the reverse direction by operating a switch of the electric screwdriver main body 2 (not shown).

また、型枠用工具１の別途使用例としては、図９に示すように、嵌合凹部１１に嵌まる外径寸法の六角ボルトＢ（六角ナットでもよい）であれば、当該六角ボルトＢを嵌合凹部１１に嵌め合わせた状態で型枠用工具１を電動ドライバ本体２で回転させるようにして用いることも可能である。 Further, as a separate use example of the formwork tool 1, as shown in FIG. 9, if the hexagon bolt B (which may be a hexagon nut) having an outer diameter that fits in the fitting recess 11, the hexagon bolt B can be used. It is also possible to use the formwork tool 1 so as to be rotated by the electric driver main body 2 in a state of being fitted into the fitting recess 11.

その際、六角ボルトＢの角部は、嵌合凹部１１における６箇所の凹部１１ｂに各々当接することにより、六角ボルトＢは、嵌合凹部１１に咬み合った状態で確実に回転させられる。このように、型枠用工具１は、型枠組み立て時以外のボルトＢやナットを締め付ける作業においても用いることができる。 At that time, the corners of the hexagon bolt B are in contact with each of the six recesses 11b in the fitting recess 11, so that the hexagon bolt B is reliably rotated in a state of being engaged with the fitting recess 11. As described above, the formwork tool 1 can also be used in the work of tightening the bolts B and nuts other than when assembling the formwork.

なお、型枠用工具１は、型枠組み立て作業やボルトＢなどの締め付け作業だけに限らず、型枠の解体作業においてもＰコンＣや型枠緊結部材Ｆの型枠パネルＰからの取り外しに際して用いることができる。 The formwork tool 1 is used not only for the formwork assembly work and the tightening work for bolts B, but also for the formwork disassembly work when the Pcon C and the formwork binding member F are removed from the formwork panel P. Can be used.

このような型枠用工具１によれば、嵌合凹部１１にＰコン本体Ｃ１を嵌合させることで型枠パネルＰの内面にＰコンＣを固定することができる一方、溝穴１２を用いて型枠緊結部材ＦのタイロッドＦ１の先端部Ｆ１ａを回転させることで当該タイロッドＦ１の基端部Ｆ１ｂをＰコンＣのネジ軸部Ｃ２に螺合させることにより、型枠パネルＰの外面に型枠緊結部材Ｆを仮組することできる。これにより、ＰコンＣの固定と型枠緊結部材Ｆの仮組との双方に共通して型枠用工具１を用いることができるので、型枠用工具１の交換・確認を要することなく型枠の組み立て・解体に係る作業を容易に行うことができる。 According to such a formwork tool 1, the P-con C can be fixed to the inner surface of the form panel P by fitting the P-con main body C1 into the fitting recess 11, while the groove hole 12 is used. By rotating the tip portion F1a of the tie rod F1 of the formwork binding member F, the base end portion F1b of the tie rod F1 is screwed into the screw shaft portion C2 of the P-con C, thereby forming a mold on the outer surface of the form panel P. The frame binding member F can be temporarily assembled. As a result, the formwork tool 1 can be used in common for both fixing the P-con C and temporarily assembling the formwork binding member F, so that the formwork tool 1 does not need to be replaced or confirmed. Work related to assembling and disassembling the frame can be easily performed.

また、円錐状の嵌合凹部１１の周方向に沿って交互に形成された複数の凸部１１ａにＰコン本体Ｃ１の外周面が線接触により確実に当接するので、ＰコンＣと嵌合凹部１１との接触摩擦力を高めてＰコンＣを確実に固定することができる。 Further, since the outer peripheral surface of the P-con main body C1 surely contacts the plurality of convex portions 11a alternately formed along the circumferential direction of the conical fitting recess 11 by line contact, the P-con C and the fitting recess 11 The contact frictional force with 11 can be increased to securely fix the P-con C.

また、十字状に形成された溝穴１２にタイロッドＦ１の先端部Ｆ１ａを挿入しやすくすることができるので、タイロッドＦ１を回転させてその基端部Ｆ１ｂをＰコンＣのネジ軸部Ｃ２に螺合させる作業を手間取ることなく容易に行うことができる。 Further, since the tip portion F1a of the tie rod F1 can be easily inserted into the groove hole 12 formed in a cross shape, the tie rod F1 is rotated and the base end portion F1b is screwed into the screw shaft portion C2 of the P-con C. The work of matching can be easily performed without any trouble.

なお、本考案は、上記の実施形態に限定されるものではない。 The present invention is not limited to the above embodiment.

例えば、嵌合凹部１１や溝穴１２の寸法は、ＰコンＣやタイロッドＦ１の先端部Ｆ１ａの寸法形状に合わせて適宜変更することができる。 For example, the dimensions of the fitting recess 11 and the groove hole 12 can be appropriately changed according to the dimensions and shape of the tip portion F1a of the P-con C and the tie rod F1.
