Description

本発明は、コンクリートの打設を行う建築現場や土木現場等で組立施工されるコンクリートを型取るための型枠パネルを支持するセパレータ軸接続金具に関する。 The present invention relates to a separator shaft connecting bracket that supports a formwork panel for casting concrete to be assembled and constructed at a construction site or a civil engineering site where concrete is placed.

建築や土木の分野における基礎として、鉄筋をベースとしたコンクリート基礎が用いられている。この様なコンクリート基礎の施工は、型枠パネルと型枠パネルとの間を現場に応じた形で一定の距離に保ち、その距離をセパレータ軸で固定する。次に、この型枠パネルと型枠パネルの間にコンクリートを流しこんで固化させ、コンクリートに十分な強度が出た段階で型枠パネルを解体し、コンクリート基礎を造り上げるといった工程がとられる。 As a foundation in the field of architecture and civil engineering, a concrete foundation based on steel bars is used. In the construction of such a concrete foundation, the distance between the formwork panel and the formwork panel is kept at a certain distance according to the site, and the distance is fixed by the separator shaft. Next, the concrete is poured between the formwork panels and solidified to solidify, and when the concrete has a sufficient strength, the formwork panels are disassembled and the concrete foundation is built up.

また、この様なコンクリート基礎の厚さは一定ではなく、例えば、高所から低所にかけて厚みが増す等の断面形状の厚さが不均一な壁の場合には、使用するセパレータ軸の長さが地上からの高さに応じて変化するので、様々な長さのセパレータ軸が必要となる。しかし、セパレータ軸の長さはそれに対応できるほど多様ではなく、長さが５ミリも違えば使用ができなくなることも多く、この様な場合は、双方の型枠パネル間の各々の接続箇所でセパレータ軸に必要な正確な長さを図面上で求めるのは大変困難であり、ほとんどが各々の現場で長さを調整することが現状である。そのため、一般的には双方の型枠パネルにそれぞれ少し長めのセパレータ軸の一方端を接続し、さらに双方の型枠パネルの中間でお互いのセパレータ軸の他方端を平行に重なり合わせて、溶接又は結合金具を用いて、双方の型枠パネルを所望の距離に保つ施工方法が用いられている。 Also, the thickness of the concrete foundation is not constant. For example, in the case of a wall with a non-uniform cross-sectional thickness such as an increase in thickness from high to low, the length of the separator shaft used Since it changes according to the height from the ground, separator shafts of various lengths are required. However, the length of the separator shaft is not so diverse that it can be accommodated, and if the length is different by 5 mm, it is often impossible to use it. In such a case, at each connection point between both formwork panels It is very difficult to obtain the exact length required for the separator shaft on the drawing, and in most cases, the length is adjusted at each site. Therefore, generally, one end of a slightly longer separator shaft is connected to both formwork panels, and the other end of each separator shaft is overlapped in parallel in the middle of both formwork panels. A construction method is used in which both the formwork panels are kept at a desired distance by using a coupling metal fitting.

これらの施工方法の従来技術として、建築に使用する２本のセパレータ軸の必要寸法を簡単に調節でき、しかも、それにかかる時間や日数の短縮を目的とした技術が開示されている（特許文献１）。また、その他にも、現場で使用される一つの例として、結合金具の本体に２本のセパレータ軸を若干の間隔を開けて通すことができる孔を設け、この孔と交差する方向に締付部材を取り付けたセパレータ結合金具が開示されている。このタイプの接続金具は、２本のセパレータ軸を本体の一つの貫通孔に同時に挿し通し、２本のセパレータ軸を適宜前後に調整しつつ所望の長さに調整し、その後に締付部材を２本のセパレータ軸の間に楔をボルトで縦方向に２本のセパレータ軸と交差する形で締め込むことによりセパレータ軸を締付接続させるものである。 As a conventional technique of these construction methods, a technique for easily adjusting the required dimensions of two separator shafts used for construction and reducing the time and the number of days required is disclosed (Patent Document 1). ). In addition, as one example used in the field, a hole that allows two separator shafts to pass through at a slight interval is provided in the main body of the fitting, and tightened in a direction crossing the hole. A separator coupling fitting having a member attached thereto is disclosed. This type of connection fitting is used to insert two separator shafts into one through-hole of the main body at the same time, adjust the two separator shafts to the desired length while adjusting the front and rear, and then tighten the fastening member The separator shaft is tightened and connected by tightening a wedge between the two separator shafts with bolts so as to intersect the two separator shafts in the vertical direction.

しかしながら、上記特許文献1に記載の技術内容では、２本のセパレータ軸を接続できるものの、接続強度を出すためにセパレータ軸を通すための貫通孔がセパレータ軸の本体部の直径と同程度の大きさである。従って、セパレータ軸端部の雄ねじ部は本体部分より円周が大きいので端部に雄ねじが形成されているセパレータ軸はそのままの状態で貫通孔に通すことができないため、施工時にはセパレータ軸端部の雄ねじ部分を切り落とす必要があり手間が掛かる。また、コンクリートの打設の際に十分な引っ張り強度を出すためにセパレータ軸を固定するためのねじ部を２つ設ける必要があり、コンクリート打設の際にも、ねじ部の露出部分が邪魔になり、厚みの無いコンクリート打設の現場及び型枠パネルの上場での接続にはヒビが入らず剥離させない程度のコンクリートの厚み確保へ支障をきたすことがある。さらに、前述の一つの孔にセパレータ軸を２本通して接続するタイプのセパレータ軸結合金具は、２本の左右のセパレータ軸を接続できるものの、セパレータ軸を接続する際の作業性が問題となる場合もある。例えば、２本の左右のセパレータ軸を双方の型枠パネルの中央で互い違いに一つの孔に通しつつ、２本のセパレータ軸の長さを同時に調整するのは長いセパレータ軸を２本同時に取り扱うことになる。その後に、締付部材を２本のセパレータ軸の間に交差する形で楔をボルトで縦方向に締め込むことによりセパレータ軸を締付接続させる構造であるため、締め込み後本体部分に縦方向にボルトの露出部分があり、コンクリート打設の際に、ボルトの露出部分が邪魔になり、厚みのないコンクリート打設現場及び型枠パネルの上場での接続にはヒビが入らず剥離させない程度のコンクリートの厚み確保へ支障をきたすことがある。また、２本のセパレータ軸を挿し通す本体の一つの貫通孔の大きさは狭く、セパレータ軸本体部分より円周が大きい端部の雄ねじ部分をそのままの状態で一つの貫通孔に通すことが困難であり、施工時にはセパレータ軸端部の雄ねじ部分を切り落とす必要がある等の手間が掛かり、また狭い場所での作業は非常に作業性が悪く時間がかかってしまうものである。さらに、一般的なセパレータ軸結合金具では、２本のセパレータ軸を仮止めすることが出来ず、締め付け固定する際にセパレータ軸が締め付け作業中に動いてしまい、所望の長さを保持するのが困難となってしまう場合がある。また、従来の製品は２本を同時に固定し本締めして止める構造であり、本締め後は緩めることが出来ず再利用が困難な構造のため、セパレータ軸を仮止めすることが出来ず、左右２本のセパレータ軸を同時に正確な長さに調整するのが難しいため、作業時間もかかり、長さ調整を間違えた場合は左右２本のセパレータ軸及び接続金具の使った部材全てが再利用できなくなるため、コストが高くついてしまうことがある。 However, in the technical content described in Patent Document 1 above, although two separator shafts can be connected, the through hole for passing the separator shaft to provide connection strength is as large as the diameter of the main body portion of the separator shaft. That's it. Therefore, since the male screw part at the end of the separator shaft is larger in circumference than the main body part, the separator shaft on which the male screw is formed cannot be passed through the through hole as it is. It takes time and effort to cut off the male thread. In addition, it is necessary to provide two screw parts for fixing the separator shaft in order to provide sufficient tensile strength when placing concrete, and the exposed part of the thread part is also obstructive when placing concrete. Therefore, there is a case where the concrete is not cracked and the concrete thickness is prevented from being peeled off at the site where the concrete is cast without thickness and at the listing of the formwork panel. Furthermore, although the separator shaft coupling fitting of the type in which two separator shafts are connected to the one hole described above can connect two left and right separator shafts, workability when connecting the separator shafts becomes a problem. In some cases. For example, adjusting the length of two separator shafts simultaneously while passing two left and right separator shafts alternately through one hole in the center of both mold panels is to handle two long separator shafts simultaneously. become. After that, since the separator shaft is tightened and connected by tightening the wedge in the vertical direction with bolts so that the clamping member intersects between the two separator shafts, There is an exposed part of the bolt, and when the concrete is placed, the exposed part of the bolt gets in the way, and the connection at the concrete placement site and the formwork panel where there is no thickness will not crack and will not peel off It may interfere with securing the thickness of concrete. Also, the size of one through hole in the main body through which the two separator shafts are inserted is narrow, and it is difficult to pass the male screw portion at the end having a larger circumference than the separator shaft main body portion through one through hole as it is. Therefore, it takes time and labor to cut off the male screw portion at the end of the separator shaft, and work in a narrow place is very inefficient and time consuming. Furthermore, in a general separator shaft coupling metal fitting, the two separator shafts cannot be temporarily fixed, and the separator shaft moves during the tightening operation when tightening and fixing, and the desired length is maintained. It can be difficult. In addition, the conventional product has a structure in which two are fixed at the same time and are tightened and tightened. After the final tightening, the separator shaft cannot be temporarily fixed because it cannot be loosened and is difficult to reuse. Since it is difficult to adjust the two left and right separator shafts to the exact length at the same time, it takes time to work, and if the length adjustment is incorrect, all the parts that use the two left and right separator shafts and the fittings are reused. Since it cannot be done, the cost may be high.

そこで本発明の主たる課題は、コンクリートを型取るための型枠パネルの組み立て作業の際に、セパレータ軸の端部に雄ねじを有したままの状態でセパレータ軸調整金具の貫通孔に容易に挿し通して、仮止めが幾度も出来て容易に調整し所望の長さを求めることが出来きて再利用も可能となる。また、コンクリート打設の際にも締め込みねじ部の露出部分が邪魔にならずコンクリートの厚み確保へ支障をきたすことがないコンパクト設計を実現した。従来製品と比べ、同等若しくはそれ以上の接続強度を有し、施工時間の短縮と材料費削減にも貢献できる今までにない新しい接続方法であるセパレータ軸接続固定金具を提供することである。 Therefore, the main problem of the present invention is that when assembling a formwork panel for molding concrete, it is easily inserted into the through hole of the separator shaft adjusting bracket with the male screw at the end of the separator shaft. Thus, the temporary fixing can be performed many times, and the desired length can be easily adjusted and reused. In addition, a compact design has been realized in which the exposed portion of the tightening screw part does not get in the way even when placing concrete and does not interfere with securing the concrete thickness. It is to provide a separator shaft connection fixing metal fitting which is a new connection method which has a connection strength equal to or higher than that of conventional products and can contribute to shortening of construction time and material cost.

(1) A separator shaft adjusting bracket, in which a through hole is formed in the separator shaft adjusting bracket, a spiral projection is formed in the through hole, and an inner diameter of the through hole is adjusted for use during construction.

And is connected to the female screw hole by a screw for stopping the movement of the adjusting separator shaft inserted into the through hole, and the screw screw is connected to the female screw. And the bottom of the end portion of the tightening screw is recessed in a mortar shape, and the spiral protrusion of the through hole and the female screw hole are attracted to one end of the adjustment separator shaft. When the through-hole is spiraled The separator shaft is characterized in that a rotational force is generated in the adjustment separator shaft along the projection orbit, and the tightening screw holding the adjustment separator shaft by the rotation rotates itself in the tightening direction.

(6) In any one of (1) to (5), a gagged surface is provided on the outer surface of the protruding portion at the end of the tightening screw to be screwed into the female screw through hole of the tightening screw. The separator shaft adjusting bracket as described. (7) A substantially conical pointed portion is provided at the mortar-shaped central portion of the bottom of the protruding portion at the end of the end of the tightening screw to be screwed into the female screw through hole of the tightening screw. (6) The separator shaft adjusting bracket according to any one of (6).

本願第１の発明によれば、締込ねじでセパレータ軸を固定する際に、締込ねじ先端が突出構造でかつ底部がすり鉢状となっていることにより、セパレータ軸に食い込ませてしっかりと固定することが可能となる。また、セパレータ軸調整金具の貫通孔に螺旋状の突起物を設けることにより、さらに強い固定力を実現することが可能となる。これら締込ねじの先端形状と貫通孔の形状による相乗効果で、調整セパレータ軸を貫通孔に挿通する際に雄ねじ部を切断せずにそのままの状態で一本の調整セパレータ軸だけを、一本の締込ねじでも接続固定する事ができ、さらに仮止めが幾度も出来て容易に調整し所望の長さを求めることが出来きて再利用も可能となる。以上のように、今までに無い新しい使用の仕方と接続方法で、双方のセパレータ軸の連結が容易でトラブル解決と材料費削減や作業効率の向上が可能となる、今までに無い新しいセパレータ軸接続固定金具を提供することが可能となる。 According to the first invention of the present application, when the separator shaft is fixed with the tightening screw, the tip of the tightening screw has a protruding structure and the bottom portion has a mortar shape, so that the separator shaft is bitten and firmly fixed. It becomes possible to do. Further, by providing a spiral projection in the through hole of the separator shaft adjusting bracket, it is possible to realize a stronger fixing force. Because of the synergistic effect of the shape of the end of the tightening screw and the shape of the through hole, when inserting the adjusting separator shaft into the through hole, only one adjusting separator shaft is left as it is without cutting the male screw portion. It is possible to connect and fix even with a tightening screw, and further, temporary fixing can be performed several times, and the desired length can be easily adjusted and reused. As described above, a new separator shaft that has never been used, which can be used to connect the two separator shafts easily and solve problems, reduce material costs, and improve work efficiency, with new ways of use and connection methods. It is possible to provide a connection fixture.

本願第２の発明によれば、セパレータ軸端部の雄ネジの後ろにねじ止めとして窪んで細くなり曲がりへの強度に弱い首部分がすぐに折れて破断してしまうのを防ぐことが可能となる。強度の無い首部分が当該セパレータ軸接続金具に形成された貫通孔端部の内径壁面に囲われて保護されて、当該セパレータ軸本体部まで少し当該貫通孔に入り込んでいる事により、コンクリートを打設する際には通常だとセパレータ軸の両端部に左右異なる方向へ引っ張りの力が掛かり、セパレータ軸の接続部分に回転力が生じて強度の無い首部分が曲がりだし折れて直ぐに破断してしまうが、本発明によればアンカーセパレータ軸の本体部分が曲りだし破断せずに、本来のアンカーセパレータ軸の強度が保つことが可能となる。 According to the second invention of the present application, it is possible to prevent the neck portion, which is recessed and thinned behind the male screw at the end of the separator shaft end, from becoming narrow and weak against bending strength, from being immediately broken and broken. Become. The non-strength neck portion is protected by being surrounded by the inner wall surface of the end of the through-hole formed in the separator shaft connection fitting, and the concrete is struck by entering the through-hole to the separator shaft body. When installing, usually both ends of the separator shaft will be pulled in different directions, and a rotating force will be generated at the connecting portion of the separator shaft, and the neck portion with no strength will bend and break immediately. However, according to the present invention, it is possible to maintain the strength of the original anchor separator shaft without bending and breaking the main body portion of the anchor separator shaft.

本願第３の発明によれば、第１の発明の効果に加えて、調整セパレータ軸を通すためのセパレータ軸調整金具とアンカーセパレータ軸を互いの側面同士を直接接続して一体型構造とすることにより、セパレータ軸の両端に左右異なる方向へ強い引く力が掛かった場合に、一本のセパレータ軸ならば軸心が同じため平行に引っ張られるが、左右別々の２本のセパレータ軸を接続固定した場合は、双方の軸心が違いずれている為に、左右２本のセパレータ軸が平行になろうとして、双方の接続部分のセパレータ軸に回
転力が生じてセパレータ軸が曲がりだし、左右２本のセパレータ軸の全体の長さが伸びることになる。この回転率は双方のセパレータ軸を接続するために平行に並べた場合に、互いの間隔が広ければ広いほど回転が大きく生じるので、回転率を抑えるには互いのセパレータ軸の間隔を極力狭くする必要があるため、セパレータ軸調整金具とアンカーセパレータ軸を直接接続し一体構造とし、セパレータ軸調整金具に接続固定された調整セパレータ軸とアンカーセパレータ軸の曲がりと伸び率を最大限に抑え防ぐことが可能となる。また、アンカーセパレータ軸とセパレータ軸調整金具を直接接続して一体型とすることにより製品の縦の高さを低くすることができ、また、一本の調整セパレータ軸だけで接続固定できることを実現したことにより接続固定部が単軸となり、従来の製品では出来なったセパレータ軸接続固定金具を、横向きに回転させて倒すことが容易に可能となる。これにより、セパレータ軸接続固定金具の***に接続している締込ねじも一緒に横向きに倒すことができ、高さ方向への影響がほとんど無いためセパレータ軸接続作業の邪魔にならず、コンクリート打設の際にもヒビが入らず剥離させない程度のコンクリートの厚み確保（一般的は鉄筋上に１０〜２０ｃｍが良いが、最低でも５ｃｍの厚みを確保 ）へ支障をきたすことなく施工することが可能となる。 According to the third invention of the present application, in addition to the effect of the first invention, the separator shaft adjusting bracket for passing the adjusting separator shaft and the anchor separator shaft are directly connected to each other to form an integrated structure. Therefore, when a strong pulling force is applied to both ends of the separator shaft in different directions on the left and right sides, if one separator shaft is used, the two shafts on the left and right are connected and fixed. In this case, since the two shaft centers are different, the two left and right separator shafts try to be parallel, a rotational force is generated in the separator shafts of both connecting portions, and the separator shaft begins to bend. The entire length of the separator shaft is extended. When the rotation rates are arranged in parallel to connect both separator shafts, the larger the distance between each other, the larger the rotation. Therefore, in order to suppress the rotation rate, the interval between the separator shafts is made as narrow as possible. Because it is necessary, the separator shaft adjusting bracket and anchor separator shaft are directly connected to form an integral structure, and the bending and elongation of the adjusting separator shaft and anchor separator shaft fixed to the separator shaft adjusting bracket can be minimized and prevented. It becomes possible. In addition, the anchor separator shaft and the separator shaft adjustment fitting are directly connected to form an integral type, so that the vertical height of the product can be lowered, and it is possible to connect and fix with only one adjustment separator shaft. As a result, the connection fixing portion becomes a single shaft, and the separator shaft connection fixing metal fitting made in the conventional product can be easily rotated and turned down. As a result, the fastening screw connected to the upper center of the separator shaft connection fixing bracket can be tilted sideways together, and there is almost no influence on the height direction, so it does not interfere with the separator shaft connection work, and concrete It is possible to construct the concrete without disturbing the securing of the concrete thickness to the extent that it will not crack and be peeled off when placing (generally 10-20 cm is good on the reinforcing bar, but at least 5 cm is ensured). It becomes possible.

本願第４の発明によれば、六角穴付き止めねじ（ホーローセット）を採用することにより、従来製品と比較してねじの頭部にねじ頭部形状が無いので、セパレータ軸調整金具と同一面近くまで埋め込む事が可能で頭部が露出しないので他の部材への引っかかりの可能性が低くさらなる作業性の向上に繋がる。また、ねじの長さが短くて施工時のセパレータ軸接続固定金具の高さを低く抑えることが可能となり、コンクリート打設の際にも厚み確保へ支障をきたすことなく施工することが可能となる。さらに、ねじ部先端の突出構造の中央が窪んでいて相手部材を押し付けて円で接触し食い込む形となるので、円形軸の固定や調整等の作業に優れ、調整セパレータ軸の仮止めが幾度も出来て容易に調整し所望の長さを簡単に求めることが可能となり一般的なボルト類及びねじ類等と比較して硬度や強度区分が高いため再利用も可能となり、より高トルクで強固にねじ先端で押し付けて絞め込むことが可能となった事で、ねじ先端突出部が深く食い込んで一本の調整セパレータ軸だけを接続固定することが可能となる。 According to the fourth invention of the present application, by adopting a hexagon socket set screw (enamel set), the screw head has no screw head shape compared to the conventional product, so the same surface as the separator shaft adjusting bracket Since it can be embedded close to the head and the head is not exposed, the possibility of catching on other members is low, leading to further improvement in workability. In addition, since the screw length is short, it is possible to keep the height of the separator shaft connection fixture at the time of construction low, and it is possible to construct without impeding the thickness securing even when placing concrete. . Furthermore, since the center of the protruding structure at the tip of the threaded portion is recessed and the mating member is pressed into contact with a circle, it will be in a shape to bite, so it is excellent for work such as fixing and adjusting the circular shaft, and the temporary fixing of the adjusting separator shaft is repeated several times It can be easily adjusted and the desired length can be easily obtained, and it can be reused because of its high hardness and strength classification compared to general bolts and screws, etc. Since the screw tip can be pressed and tightened, the protruding portion of the screw tip can be deeply cut and only one adjusting separator shaft can be connected and fixed.

以下、本発明の実施の形態について図面を参照して説明する。図１は本発明のセパレータ軸接続固定金具の第１の実施形態の概略図を示すものである。本実施形態では、セパレータ軸調整金具１とセパレータ軸接続金具２の側面同士を固定させてセパレータ軸接続固定金具１００とする。締込ねじ３は、セパレータ軸調整金具１に形成した雌ねじ孔４に先端を螺合して接続される。当該雌ねじ孔はセパレータ軸調整金具１の上面の略中央に形成する。また、セパレータ軸調整金具１の貫通孔５の内部には螺旋状の突起物を形成する。当該貫通孔５の形状は特に限定されるものではないが略円筒状のものが好ましく、内部形状は特に限定する物ではないが、挿し通された調整セパレータ軸７が常に当該貫通孔5の底面中央に自然と位置させるため、当該貫通孔５の底面がすり鉢状で丸みをおびた形にすることが好ましい。当該螺旋状の突起物の形状は貫通孔５内部の一方端から他方端までいずれかの場所に形成されていれば良いが、締込ねじの下部周辺に形成することがより好ましく、調整セパレータ軸７をより強固に固定するためには貫通孔５すべてに形成することがより好ましい。螺旋状の突起物は、螺旋を形成する突起物の間隔や突起物の先端形状等を特に限定するものではないが、ねじ山の間隔が狭くて、突起物の角度がきつく鋭利なものがより好ましい。施工時にセパレータ軸を接続固定する際には、前記貫通孔５には両端に雄ねじが形成されたままの調整セパレータ軸７を挿し通して締込ねじ３を軽く締め込んで仮止めしておき、長さを調整した後に六角レンチや六角レンチインパクト等でしっかりと締め込んで調整セパレータ軸７を固定させるものである。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a schematic view of a first embodiment of a separator shaft connection fixture according to the present invention. In the present embodiment, the side surfaces of the separator shaft adjusting bracket 1 and the separator shaft connecting bracket 2 are fixed to form the separator shaft connecting fixing bracket 100. The tightening screw 3 is connected to a female screw hole 4 formed in the separator shaft adjusting bracket 1 by screwing the tip. The female screw hole is formed at substantially the center of the upper surface of the separator shaft adjusting bracket 1. A spiral projection is formed inside the through hole 5 of the separator shaft adjustment fitting 1. Although the shape of the through hole 5 is not particularly limited, a substantially cylindrical shape is preferable, and the internal shape is not particularly limited, but the inserted adjustment separator shaft 7 always has a bottom surface of the through hole 5. In order to be naturally positioned in the center, it is preferable that the bottom surface of the through hole 5 has a mortar shape and is rounded. The shape of the spiral protrusion may be formed anywhere from one end to the other end inside the through-hole 5, but is more preferably formed around the lower part of the tightening screw. In order to fix 7 more firmly, it is more preferable to form in all the through-holes 5. The spiral protrusions do not particularly limit the interval between the protrusions forming the spiral or the tip shape of the protrusions, but sharper ones with narrower screw thread intervals and tight protrusion angles. preferable. When connecting and fixing the separator shaft at the time of construction, the adjustment separator shaft 7 with the male screw formed on both ends is inserted into the through hole 5 and the fastening screw 3 is lightly tightened and temporarily fixed. After adjusting the length, the adjusting separator shaft 7 is fixed by firmly tightening with a hex wrench or hex wrench impact.

セパレータ軸接続金具２の貫通孔６の内部にはセパレータ軸の雄ねじを螺合可能な雌ねじが形成されており、既存のセパレータ軸８Ａ端部の雄ねじを貫通孔６に挿し込み、雌ねじと螺合してセパレータ軸接続固定金具１００と固定する。調整セパレータ軸７と既存のセパレータ軸８Ａのセパレータ軸接続固定金具１００に固定されていない方の端部にも雄ねじが形成されており、施工現場の状況に応じて他の構造物に取り付けることができる。例えば、コンクリート型枠の施行であれば、この雄ねじをピーコン軸に形成された雌ねじに螺合させ、さらにピーコン軸の端部に設けられた雄ねじをコンクリート型枠パネルの孔に挿し込んで、型枠パネルの裏側から締付金具をピーコン軸の雄ねじに捻じ込んで螺合してピーコン軸をコンクリート型枠パネルに固定するような工程をとる。 Inside the through hole 6 of the separator shaft connection fitting 2, a female screw capable of being screwed into the male screw of the separator shaft is formed. The male screw at the end of the existing separator shaft 8A is inserted into the through hole 6 and screwed into the female screw. Then, the separator shaft connection fixing metal fitting 100 is fixed. Male screws are also formed at the ends of the adjustment separator shaft 7 and the existing separator shaft 8A that are not fixed to the separator shaft connection fixture 100, and can be attached to other structures according to the situation at the construction site. it can. For example, in the case of concrete formwork enforcement, this male screw is screwed into the female screw formed on the peakon shaft, and the male screw provided at the end of the peakon shaft is inserted into the hole of the concrete formwork panel, From the back side of the frame panel, the fastening metal fitting is screwed into the male screw of the peakon shaft and screwed to fix the peakon shaft to the concrete formwork panel.

図２は本実施形態の締込ねじ３の断面図を示す。本実施形態の締込ねじ３としては、全ねじ状の六角穴付き止めねじ（ホーローセット）を採用した。当該締込ねじ３の先端構造は、雌ねじ孔４に螺合させる方の端部が突出した構造（突出部）、かつ、この突出部の底部がすり鉢状に窪んだ形状を有する。突出部の構造としては、全ねじ部から先端部の先に向かうにつれて、徐々に全ねじ部の直径より小さな径となる構造である。締込ねじ３の先端をこの様な構造にすることにより、貫通孔５に挿し込まれた調整セパレータ軸上部の面にしっかりと食い込んだ状態とすることができ、平らな先端構造等と比較してより強い固定力を実現することが可能となる。また、この突出部と反対の他方端部上面には六角形の穴が形成されており、調整セパレータ軸を固定する際に六角レンチや六角レンチインパクトなどで締め付けることが可能となる。この様な構造とすることにより、締め付け作業が簡易になり、作業性も向上し、さらにプラスやマイナスのドライバー等で締め付けるタイプのねじよりも、より強固に締め付けることが可能となる。 FIG. 2 shows a sectional view of the fastening screw 3 of the present embodiment. As the tightening screw 3 of the present embodiment, an all-screw hexagon socket set screw (enamel set) was employed. The distal end structure of the tightening screw 3 has a structure in which an end portion to be screwed into the female screw hole 4 protrudes (protrusion portion), and a shape in which the bottom portion of the protrusion portion is recessed in a mortar shape. As the structure of the protruding portion, the diameter gradually becomes smaller than the diameter of the entire screw portion as it goes from the entire screw portion to the tip of the tip portion. By making the tip of the tightening screw 3 into such a structure, it is possible to ensure that it is firmly intruded into the upper surface of the adjusting separator shaft inserted into the through-hole 5, compared with a flat tip structure, etc. It is possible to realize a stronger fixing force. In addition, a hexagonal hole is formed on the upper surface of the other end opposite to the protruding portion, and when the adjustment separator shaft is fixed, it can be tightened with a hex wrench or a hex wrench impact. By adopting such a structure, the tightening work is simplified, workability is improved, and it is possible to tighten more firmly than the type of screws that are tightened with a plus or minus screwdriver.

締込ねじ３の先端構造としては、本実施形態で用いた形状に限定されるものではなく、セパレータ軸調整金具１の雌ねじ孔４に螺合させる締込ねじ３の端部の突出部の側面にギザ状面を設けた形状や、先端の突出部底部のすり鉢状中央部に略円錐状の尖端部を設けた形状のもの、またはこれらの形状を併用した先端構造が使用できる。これらの形状の締込ねじ３を用いることにより、施工時に調整セパレータ軸で双方の型枠パネルの距離を調整する際に、軽く締め込んで仮止めを幾度とすることが可能となり、所望の長さを容易に得ることができる。また、 調整セパレータ軸７をセパレータ軸調整金具１の貫通孔５の内部で底面に上部からしっかり押し付けて止めることができる点でより優れた固定力を実現することが可能である。 The tip structure of the tightening screw 3 is not limited to the shape used in the present embodiment, and the side surface of the protruding portion at the end of the tightening screw 3 to be screwed into the female screw hole 4 of the separator shaft adjusting bracket 1. A shape having a serrated surface, a shape having a substantially conical point at the mortar-shaped central portion at the bottom of the protruding portion at the tip, or a tip structure using these shapes in combination can be used. By using the tightening screws 3 of these shapes, when adjusting the distance between the two form panel panels with the adjusting separator shaft at the time of construction, it is possible to temporarily tighten and temporarily fix the desired length. Can be easily obtained. Further, it is possible to realize a better fixing force in that the adjustment separator shaft 7 can be firmly pressed from the upper part to the bottom surface inside the through hole 5 of the separator shaft adjustment fitting 1 and stopped.

本実施形態で用いる締込ねじ３の硬さは特に限定されるものではなく一般的に使用されているねじ類の硬度のものが使用できる。なお、より強固にセパレータ軸を接続固定させるためには、材質が鋼製の場合は表面処理及び熱処理をされた強度区分が４５ＨＲＣ以上で、ステンレス製の場合は１２Ｈ又２１Ｈ等、その他にもより強度区分が高いものを使うことが好ましい。これにより、六角レンチや六角レンチインパクト等で締め込む際により高トルクで締め付けることが可能になり、結果として調整セパレータ軸を強固に固定することが可能となる。 The hardness of the tightening screw 3 used in the present embodiment is not particularly limited, and one having a hardness of generally used screws can be used. In order to more firmly connect and fix the separator shaft, the strength classification after surface treatment and heat treatment is 45HRC or more when the material is steel, and 12H or 21H when stainless steel is used. It is preferable to use one having a high strength category. This makes it possible to tighten with higher torque when tightening with a hexagon wrench or a hexagon wrench impact, and as a result, the adjustment separator shaft can be firmly fixed.

図３はセパレータ軸接続固定金具１００を側面からみた断面図を示す。セパレータ軸調整金具１の貫通孔５は前述の通り螺旋状の突起物を形成する。貫通孔５の径の大きさは、調整セパレータ軸の端部に雄ねじを有したままの状態で容易に挿し通すことができ、自由に前後にスライドさせて動かすことができる程度の大きさである。これにより、施工時に調整セパレータ軸で双方の型枠パネルの距離を調整する際にわざわざ雄ねじ部分を切り取らずにそのままの状態で容易に差し込み利用できるため、作業の手間や時間を短縮することが可能となる。また、セパレータ軸調整金具１の上面には、貫通孔５まで到達するように雌ねじ孔４を形成する。この雌ねじ孔４は締込ねじ３を螺合させるものであり、これにより、貫通孔５に挿通した調整セパレータ軸７を、締込ねじ３と貫通孔５に設けた螺旋状の突起物でしっかりと固定させることができる構造となる。より具体的には、締込ねじ３を締め付ける際に、押し付けられ固定される調整セパレータ軸７の下部が貫通孔５の螺旋状の突起物に食い込んだ状態となり、突起痕が出来きて、調整セパレータ軸７の滑りへの抵抗力を生ませることが可能となる。また、コンクリート打設の際に調整セパレータ軸７の一方端に強い引力が掛かると、貫通孔の螺旋状の突起物の軌道に沿って調整セパレータ軸７に回転力が生じ、その回転により同時に調整セパレータ軸７を押さえ付けている締込ねじ３が自らを締め付け方向に回転することになり、調整セパレータ軸７は自ら締め込みねじ３に向かい、より締込ねじ３の先端部が食い込んだ状態となり、調整セパレータ軸７の上下面でさらに強い固定力を実現することが可能となる。 FIG. 3 shows a cross-sectional view of the separator shaft connection fixture 100 as viewed from the side. As described above, the through hole 5 of the separator shaft adjustment fitting 1 forms a spiral projection. The size of the diameter of the through-hole 5 is such a size that it can be easily inserted with the male thread at the end of the adjustment separator shaft and can be freely slid back and forth. . As a result, when adjusting the distance between the two formwork panels with the adjustment separator shaft at the time of construction, it is possible to easily insert and use as it is without cutting off the male screw part, so it is possible to reduce the labor and time of work. It becomes. Further, a female screw hole 4 is formed on the upper surface of the separator shaft adjusting bracket 1 so as to reach the through hole 5. The female screw hole 4 is used for screwing the tightening screw 3, whereby the adjustment separator shaft 7 inserted into the through hole 5 is firmly fixed by a helical protrusion provided in the tightening screw 3 and the through hole 5. It becomes a structure that can be fixed. More specifically, when the tightening screw 3 is tightened, the lower part of the adjustment separator shaft 7 that is pressed and fixed bites into the spiral protrusion of the through hole 5, and a protrusion mark is formed, thereby adjusting. It is possible to generate resistance against the slip of the separator shaft 7. In addition, if a strong attractive force is applied to one end of the adjusting separator shaft 7 during concrete pouring, a rotational force is generated in the adjusting separator shaft 7 along the trajectory of the spiral projection of the through hole, and the adjustment is simultaneously performed by the rotation. The tightening screw 3 holding the separator shaft 7 rotates itself in the tightening direction, and the adjusting separator shaft 7 faces the tightening screw 3 itself, and the tip of the tightening screw 3 is further bitten. Further, a stronger fixing force can be realized on the upper and lower surfaces of the adjusting separator shaft 7.

セパレータ軸接続金具２の貫通孔６には雌ねじを形成する。セパレータ軸接続金具２の貫通孔６の内径は、左右端部が差し込まれる既存のセパレータ軸８Ａ端部の雄ねじがそのまま入る程度の大きさの無ねじの孔であり、差し込まれる既存のセパレータ軸８Ａの端部の雄ねじと本体部の間にあるねじ止めの役割と、叩き折る目的の本体部より凹んで細くなり曲がりへの強度に弱く折れて破断しやすいセパレータ軸の首部１３が入り込むとともに、本来の強度がある本体の軸部分を少し入れ込むことができる。この様に、貫通孔６の内径壁面に囲われて保護される程度の深さの孔を貫通孔６の左右端部に形成する事によって、コンクリートを打設する際にセパレータ軸の両端部に左右異なる方向へ引っ張りの力が掛かり、セパレータ軸の接続部分に回転力が生じて本体部分が曲がりだした際にも、差し込まれた既存のセパレータ軸は、破断することなくセパレータ軸本来の強度を発揮し実現することができる。また、中央部には雌ねじを形成しているため、差し込まれる既存のセパレータ軸８Ａの端部の雄ねじと螺合することができ、簡単にセパレータ軸接続固定金具１００を接続固定させる事が可能となる。これにより、長さを問わずすべての長さに対応が可能で、簡単にセパレータ軸接続固定金具１００を接続固定させる事が可能となることで、何らかの要因で寸法が合わなくなったトラブルを容易に解決することが出来る。さらに貫通孔６の左右に無ねじの孔を形成することで、施工時に左右どちらからでも既存のセパレータ軸を差し込み螺合することが出来ることで、取り付け方にとらわれず作業性の向上に繋がる。 An internal thread is formed in the through hole 6 of the separator shaft connection fitting 2. The inner diameter of the through-hole 6 of the separator shaft connection fitting 2 is a non-threaded hole that is large enough to accept the male screw at the end of the existing separator shaft 8A into which the left and right ends are inserted. The threaded part between the male screw at the end of the body and the body part, and the neck part 13 of the separator shaft that enters the body part intended to be struck and that is recessed and thin, weak against bending strength and easy to break, The shaft part of the main body with the strength of can be inserted a little. In this way, by forming holes with a depth that is protected by being surrounded by the inner wall surface of the through-hole 6 at the left and right ends of the through-hole 6, Even when a pulling force is applied in different directions on the left and right, and a rotating force is generated at the connecting part of the separator shaft and the main body part begins to bend, the existing separator shaft inserted does not break, and the original strength of the separator shaft is maintained. It can be demonstrated and realized. In addition, since a female screw is formed in the central portion, it can be screwed with a male screw at the end of the existing separator shaft 8A to be inserted, and the separator shaft connecting fixture 100 can be easily connected and fixed. Become. As a result, it is possible to handle all lengths regardless of the length, and it is possible to easily connect and fix the separator shaft connection fixture 100, so that it is easy to troubleshoot dimensions that are not suitable for some reason. It can be solved. Furthermore, by forming screw-free holes on the left and right sides of the through-hole 6, the existing separator shaft can be inserted and screwed from either the left or right during construction, leading to improved workability regardless of the mounting method.

図４はセパレータ軸接続固定金具１００を正面からみた断面図を示す。本
実施形態のセパレータ軸調整金具１とセパレータ軸接続金具２は円形の貫通孔を有する六角形の筒状のものを用いる。これらは、この様な形状の金具を製造して使用しても良いし、市販の六角高ナットを使用しても良い。本実施形態のセパレータ軸調整金具１とセパレータ軸接続金具２は六角形の一つの側面同士を溶接にて接続する。本実施形態では、溶接を用いたが接続方法はこの方法に限られるものではない。本実施形態のように、金具の外形を六角形とすることにより、内形が円形の貫通孔の全面に対して、強度的にバランスが良い外壁肉厚の確保ができて、均等な対角がある構造なので、掛かる力を均等に分散吸収ができて強度的に非常に強くなる。また、安価な部材で一般的なボルト類及びねじ類等と比較して硬度や強度区分が高い、締込ねじをより高トルクで強固に絞め込むことが可能となる。さらに６面全てに対辺が略均等にあるため、２つの金具の平面同士を接続することが可能となり、接着面が多い為ねじれ等の力にも強く、強力に接続固定することができる。また金具の内形を円形の貫通孔とすることにより、本実施形態のセパレータ軸調整金具１においては、施工の際に貫通孔５に調整セパレータ軸７が容易に挿し通され常にこの貫通孔の底面中央に自然と位置させるのを可能とした。さらに本実施形態のセパレータ軸接続金具２の貫通孔６においては、内部には既存のセパレータ軸８Ａ端部の雄ねじをそのままの状態で挿し込める程度の大きさで当該既存のセパレータ軸の首部１３が入り込むとともに、本体の軸部分が少し入り込む深さの無ねじの孔を左右端部に形成し、中央部には当該既存のセパレータ軸８Ａの雄ねじを螺合可能な雌ねじが形成されておるが、このようは形体の構造物を製作するにあたっては、外形が六角形の六角高ナットに細工を加え造る方が、他の部材よりはるかに製造コストが安くなることができる。新製品の開発においては、従来の製品に比べ、機能的には同等もしくはそれ以上に良い物で、安価な物を要求され、そうでないと新製品は売れないという過酷な状況の中、本願発明のセパレータ軸接続固定金具も、安価な部材に、独創的な思考と、セパレータ軸調整金具１とセパレータ軸接続金具２と締込ねじ３のこれらの総合的なコンビネーションを加え、改良に改良を重ねて研究し、機能的に優れた製品を開発するものである。本発明は創意工夫を重ね、これらの課題解決に成功し、十分な引張強度を実現できるセパレータ軸接続金具を開発するに至ったものであり、安価な部材で従来製品と比べ同等若しくはそれ以上の強度を有する商品の製品化が可能となることで、今までに無い新しい使用の仕方と接続方法で施工時間の短縮と材料費削減にも貢献できる。 FIG. 4 shows a cross-sectional view of the separator shaft connection fixture 100 as seen from the front. The separator shaft adjusting bracket 1 and the separator shaft connecting bracket 2 of this embodiment are hexagonal cylinders having circular through holes. For these, a metal fitting having such a shape may be manufactured and used, or a commercially available hexagonal high nut may be used. The separator shaft adjusting bracket 1 and the separator shaft connecting bracket 2 of the present embodiment connect one side of the hexagon by welding. In this embodiment, welding is used, but the connection method is not limited to this method. As in the present embodiment, the outer shape of the metal fitting is a hexagonal shape, so that the outer wall thickness with a good balance in strength can be secured with respect to the entire surface of the through hole having a circular inner shape, and a uniform diagonal Since there is a structure, the applied force can be dispersed and absorbed evenly and the strength becomes very strong. In addition, it is possible to tighten the tightening screw firmly with higher torque, which is an inexpensive member and has higher hardness and strength classification than general bolts and screws. Furthermore, since the opposite sides are substantially even on all six surfaces, it is possible to connect the two metal plates to each other, and since there are many bonding surfaces, they are strong against forces such as torsion and can be strongly connected and fixed. Further, by making the inner shape of the metal fitting a circular through hole, in the separator shaft adjusting metal fitting 1 of the present embodiment, the adjustment separator shaft 7 is easily inserted into the through hole 5 at the time of construction, and the through hole is always inserted. It was possible to position it naturally in the center of the bottom. Furthermore, in the through-hole 6 of the separator shaft connection fitting 2 of the present embodiment, the neck portion 13 of the existing separator shaft is large enough to insert the male screw at the end of the existing separator shaft 8A as it is. While entering, and forming a screw-free hole with a depth that the shaft portion of the main body slightly enters in the left and right ends, a female screw capable of screwing the male screw of the existing separator shaft 8A is formed in the center, Thus, when manufacturing the structure of a form, the manufacturing cost can be made much cheaper than other members by making a hexagonal hexagonal high nut with a work. In the development of new products, the invention of the present application is in a harsh situation in which new products cannot be sold unless they are required to be cheaper and functionally equivalent or better than conventional products. Separator shaft connection fixing brackets are also improved by adding original ideas and a comprehensive combination of separator shaft adjustment bracket 1, separator shaft connection bracket 2 and tightening screw 3 to an inexpensive member. To develop functionally superior products. The present invention has been invented, succeeded in solving these problems, and has developed a separator shaft connecting bracket that can realize sufficient tensile strength, and is equivalent to or higher than conventional products with inexpensive members. By making it possible to commercialize products with strength, it is possible to contribute to shortening construction time and material costs with new ways of using and connecting methods that have never existed before.

図５は本発明のセパレータ軸接続金具の第２の実施形態を示す概略図、図６は第２の実施形態の断面図、図７は第２の実施形態を正面から見た図である。第１の実施形態と異なる点としては、セパレータ軸接続固定金具１００を、セパレータ軸調整金具１とアンカーセパレータ軸８Ｂから構成する点である。セパレータ軸調整金具１の構成は第１の実施形態と同様である。本第２の実施形態では、セパレータ軸調整金具１の底面にアンカーセパレータ軸８Ｂの側面を溶接することにより接続させてセパレータ軸接続固定金具１００を形成する。なお、本実施形態では溶接で接続したがそれに限られるものではない。 FIG. 5 is a schematic view showing a second embodiment of the separator shaft connection fitting of the present invention, FIG. 6 is a sectional view of the second embodiment, and FIG. 7 is a view of the second embodiment as viewed from the front. The difference from the first embodiment is that the separator shaft connection fixture 100 is composed of the separator shaft adjustment fixture 1 and the anchor separator shaft 8B. The configuration of the separator shaft adjustment fitting 1 is the same as that of the first embodiment. In the second embodiment, the separator shaft connection fixing bracket 100 is formed by welding the side surfaces of the anchor separator shaft 8B to the bottom surface of the separator shaft adjustment bracket 1 by welding. In addition, in this embodiment, although connected by welding, it is not restricted to it.

本第２の実施形態のように、セパレータ軸調整金具１の底面にアンカーセパレータ軸８Ｂの側面を溶接することにより、施工の際に調整セパレータ軸７の１本のみで長さを調整して接続固定させることを実現できる。本第２の実施形態をとることにより、接続固定部を単軸とすることができ、セパレータ軸接続固定金具１００自体を横向きに回転させて倒すことが容易となる。これにより、接続固定金具の上部に螺合されている締込ねじも横向きに回転し倒すことができ、コンクリート打設時の高さ方向上部への出っ張りをなくすことができ、高さへの影響をほぼ無くすことが可能となる。このため、施工の際に他の部材への引っかかりが少なく作業の邪魔にならず、コンクリート打設の際にもコンクリートの厚み確保へ支障をきたすことなく施工することが可能となる。 As in the second embodiment, by welding the side surface of the anchor separator shaft 8B to the bottom surface of the separator shaft adjustment fitting 1, the length is adjusted by only one of the adjustment separator shafts 7 at the time of construction. It can be fixed. By adopting the second embodiment, the connection fixing portion can be a single axis, and the separator shaft connection fixing metal fitting 100 itself can be easily rotated and tilted down. As a result, the tightening screw that is screwed onto the upper part of the connection fixing bracket can also be rotated sideways, and the protrusion to the upper part in the height direction when placing concrete can be eliminated, affecting the height. Can be almost eliminated. For this reason, there is little catching on other members at the time of construction, and it does not interfere with the work, and it is possible to construct the concrete without disturbing the securing of the concrete thickness.

第２の実施形態で使用するアンカーセパレータ軸８Ｂは、取り付け対象物に取り付けた際にアンカー的な機能も持つため、第１の実施形態で使用する既存のセパレータ軸８Ａと比較して短いものを使用することができる。特に使用できる長さは限定されるものではないが、施工現場の型枠間の距離などに応じて適切な長さの物を選択することができる。アンカー的な機能を発揮するための長さとしては、１０〜１００ｃｍ程度のものがより好ましい。この程度の長さであれば、セパレータ軸接続の作業性も良く、対象物に取り付けた際に取り付け部を損傷させない点でも優れる。 Since the anchor separator shaft 8B used in the second embodiment also has an anchor function when attached to an attachment object, the anchor separator shaft 8B is shorter than the existing separator shaft 8A used in the first embodiment. Can be used. Although the length which can be used especially is not limited, the thing of suitable length can be selected according to the distance between the molds of a construction site, etc. The length for exhibiting the anchor function is more preferably about 10 to 100 cm. If it is this length, the workability of the separator shaft connection is good, and it is excellent in that the attachment portion is not damaged when attached to the object.

First, as an example, one end of the existing separator shaft 8A is connected and fixed to the side surface of the mold frame with a pecon metal fitting or the like. Next, the male screw at the other end of the existing separator shaft 8A is screwed into and connected to the through hole 6 of the separator shaft connection fitting 2 of the separator shaft connection fixture 100 according to the first embodiment of the present invention. Thereafter, the adjustment separator shaft 7 is inserted into the through hole 5 of the separator adjustment fitting 1 with a male screw attached from one end, and temporarily fixed with the tightening screw 3, while the other end is attached to the other side of the formwork with a pecon fitting or the like. Connect and fix, adjust the distance between both molds appropriately, and then tighten the screw 3 at the top of the through hole that was loosely screwed together and temporarily connected with a hexagon wrench or hex wrench impact, etc. Tighten firmly to firmly connect and fix the adjustment separator shaft 7 and the separator shaft connection fixture 100. Similarly, at the stage where the separator shaft connection fixing metal fittings 100 are used to fix the required number and the distance between the molds can be kept constant, the concrete is finally placed to complete the construction. In addition, the separator shaft connection fixing metal fitting 100 of the first embodiment can be used, and two appropriate separator shafts remaining in other constructions can be used in the connection method, and can be connected to each other. One end of one suitable separator shaft (existing separator shaft 8A) is connected and fixed to the side surface of the mold frame with a pecon fitting or the like, and the male screw on the other end is screwed into the through hole 6 of the separator shaft connection fitting 2 for connection. The other suitable separator shaft (adjustment separator shaft 7) is inserted into the through hole 5 of the separator adjusting bracket 1 with a male screw attached from one end and temporarily fixed with the tightening screw 3, while the other end is connected to the peacon bracket. Etc., and connect the other mold side to the side of the mold, fix it properly, adjust the distance between the two molds properly, tighten the clamping screw 3 firmly, and the other appropriate separator shaft (adjustment separator shaft 7) The separator shaft connection fixing metal fitting 100 can be firmly connected and fixed. Therefore, regardless of the length of the appropriate separator shaft, it can be easily attached to the tip of the appropriate separator shaft at the required location in the same way as an attachment, and should be compatible with all lengths. It is possible to connect two separator shafts easily, and furthermore, the temporary fixing can be made several times, and it can be easily adjusted to obtain a desired length, which can be reused and contribute to material cost reduction. An unprecedented new separator shaft connection fixture can be provided.

また、コンクリートの打設を行う建築現場や土木現場等でコンクリート型枠組立施工する際、なんらかの要因により最初に組立てた寸法と双方の型枠パネルの間隔がくるってしまい当初用意していた既存のセパレータ軸の長さが合わないことが多分に発生する。このような場合、通常は新たに寸法の合ったセパレータ軸を準備する必要がある。または当初用意していた当該既存のセパレータ軸とは別に、所望の長さに必要な新たな調整セパレータ軸を準備して、２本のセパレータ軸を接続する必要があるが、接続する際に、双方の型枠パネルの真ん中で必ずしも繋ぐ必要はなく、長さが合わないと気が付いたどちらかの端で接続し繋ぐこと可能である。この様な場合、本発明の第１の実施形態に係るセパレータ軸接続固定金具１００によれば、一方端が型枠パネルに接続されている長さが合わなくなった既存のセパレータ軸８Ａの他方端の雄ネジ部分に、まずはセパレータ軸接続金具２の貫通孔６を挿し込み螺合させることで、当該既存のセパレータ軸８Ａにセパレータ軸接続固定金具１００が容易に接続され、当該既存のセパレータ軸が接続固定金具付のセパレータ軸となり、当該既存のセパレータ軸８Ａが、アンカーセパレータ軸８Ｂの役割を担うことで、当該アンカーセパレータ軸８Ｂが一方の型枠側面に接続固定されたことと同じことになり、その後、所望の長さに必要な新たな調整セパレータ軸７を用いて、他方型枠側面に接続して固定する。調整セパレータ軸７の基本的な固定方法は前述の第１の実施形態と同様である。このように、既存のセパレータ軸の長さを問わず全ての長さに対応が出来るセパレータ軸接続金具を必要とされる場所で当該既存のセパレータ軸の先端にアタッチメントのような考え方で、当該既存のセパレータ軸に螺合して接続することが可能となり、双方のセパレータ軸の連結が容易でトラブル解決と材料費削減や作業効率の向上が可能となる。 In addition, when assembling concrete formwork at a construction site or civil engineering site where concrete is placed, the dimensions of the first assembly and the distance between both formwork panels will be reduced due to some factors. Often the length of the separator shaft does not match. In such a case, it is usually necessary to prepare a separator shaft having a new size. Or, apart from the existing separator shaft that was originally prepared, it is necessary to prepare a new adjusting separator shaft necessary for the desired length and connect the two separator shafts. It is not always necessary to connect them in the middle of both formwork panels, and it is possible to connect and connect at either end where you noticed that the lengths do not match. In such a case, according to the separator shaft connection fixing metal fitting 100 according to the first embodiment of the present invention, the other end of the existing separator shaft 8A whose one end is no longer connected to the formwork panel. First, the through-hole 6 of the separator shaft connection fitting 2 is inserted into and screwed into the male screw portion, so that the separator shaft connection fixing fitting 100 is easily connected to the existing separator shaft 8A. It becomes a separator shaft with a connection fixing bracket, and the existing separator shaft 8A plays the role of the anchor separator shaft 8B, which is the same as the anchor separator shaft 8B being connected and fixed to the side surface of one mold. Then, using the new adjustment separator shaft 7 necessary for a desired length, the other side of the mold is connected and fixed. The basic fixing method of the adjustment separator shaft 7 is the same as that in the first embodiment. In this way, the existing separator shaft connection fitting that can accommodate all lengths regardless of the length of the existing separator shaft is used in a place like the attachment to the tip of the existing separator shaft. The separator shaft can be screwed and connected, and the separator shafts can be easily connected to each other, so that trouble can be solved, material costs can be reduced, and work efficiency can be improved.

さらなるセパレータ軸接続固定金具１００の使用方法の使用例としては、先ずは、短い既存のセパレータ軸８Ａの一方端を、本発明の第１の実施形態に係るセパレータ軸接続固定金具１００のセパレータ軸接続金具２の貫通孔６に当該短い既存のセパレータ軸８Ａの一方端の雄ねじを螺合して接続させることで、当該短い既存のセパレータ軸８Ａにセパレータ軸接続固定金具１００が容易に接続され、当該短い既存のセパレータ軸が接続固定金具付のセパレータ軸となり、当該短い既存のセパレータ軸８Ａが、アンカーセパレータ軸８Bの役割を担うことで、アンカーセパレータ軸付きのセパレータ軸接続固定金具としての働きができることになり、本第２の実施形態のセパレータ軸接続固定金具１００と同様となり、本実施形も同じである。以上のように、一本の既存のセパレータ軸８Ａだけをセパレータ軸調整金具１と強固な接続強度をみたし接続することが可能となったことで、前記説明のような今までに無い新しい使用のしかたと接続方法で、双方のセパレータ軸の連結が容易でトラブル解決と材料費削減や作業効率の向上が可能となる。また、本発明の第１の実施形態のセパレータ軸接続固定金具は、前記説明のように寸法が合わなくて困った全ての場合、及び本発明の第2の実施形態のアンカーセパレータ軸8 Bとしての、二通りの利用法ができるため第１の実施形態のセパレータ軸接続固定金具があれば、全ての場面で対応ができるので、使用者のニーズにあった使用方法を提供することが可能となる。 As a further example of how to use the separator shaft connection fixture 100, first, one end of a short existing separator shaft 8A is connected to the separator shaft connection of the separator shaft connection fixture 100 according to the first embodiment of the present invention. By connecting a male screw at one end of the short existing separator shaft 8A to the through hole 6 of the metal fitting 2 and connecting it, the separator shaft connection fixing metal fitting 100 is easily connected to the short existing separator shaft 8A. The short existing separator shaft becomes a separator shaft with a connection fixing bracket, and the short existing separator shaft 8A serves as the anchor separator shaft 8B, thereby functioning as a separator shaft connection fixing bracket with an anchor separator shaft. Thus, the separator shaft connection fixing metal fitting 100 of the second embodiment is the same, and this embodiment is also the same. As described above, it is possible to connect only one existing separator shaft 8A to the separator shaft adjusting bracket 1 with a strong connection strength. With the method and connection method, the separator shafts on both sides can be easily connected to solve problems, reduce material costs, and improve work efficiency. In addition, the separator shaft connection fixing bracket of the first embodiment of the present invention is used in all cases where the dimensions do not match as described above, and as the anchor separator shaft 8 B of the second embodiment of the present invention. Since the separator shaft connection fixing bracket of the first embodiment can be used in all situations because it can be used in two ways, it is possible to provide a usage method that meets the needs of the user. Become.

次に、本発明の第２の実施形態に係るセパレータ軸接続固定金具１００について説明する。調整セパレータ軸７の固定方法としては、第１の実施形態と同様の手法が考えられる。第２の実施形態に係るセパレータ軸接続固定金具１００については、まずアンカーセパレータ軸８Ｂの雄ねじ部を、一方の型枠に固定することにより、一つのセパレータ軸とセパレータ軸接続固定金具１００も同時に設置する状態となる。次に、調整セパレータ軸７を一方端から雄ねじが付いたままの状態で切断せずに貫通孔５に挿し通して貫通させ、締込ねじ３で仮止めしつつ、調整セパレータ軸７をスライドしながら、双方の型枠間の距離を適切に調整し、他方端の雄ネジ部をもう片方の型枠に固定する。次に、締込ねじ３を締め付けて調整セパレータ軸７をしっかり接続固定する。また、本第２の実施形態のセパレータ軸接続固定金具１００を、コンクリート打設の際に、コンクリート厚を確保するために必要ならば当該打設する高さ方向から約９０°横向きに傾けた状態で固定することが出来
る。同様にセパレータ軸接続固定金具１００により必要なセパレータ軸の数だけ固定して型枠間の距離を一定に保つことができた段階で、最後にコンクリートを打設して施工終了とする。本第２の実施形態の施行においては、予めセパレータ軸接続固定金具１００を型枠等の取り付け対象物に必要な数だけ取り付けておき、その後にまとめて適正な距離の調整セパレータ軸７を用いて長さ調整と接続固定を行うこともできる点で、作業性や作業効率の向上が可能となる。 Next, a separator shaft connection fixture 100 according to a second embodiment of the present invention will be described. As a method of fixing the adjustment separator shaft 7, the same method as in the first embodiment can be considered. With respect to the separator shaft connection fixture 100 according to the second embodiment, by first fixing the male thread portion of the anchor separator shaft 8B to one mold, one separator shaft and the separator shaft connection fixture 100 are also installed at the same time. It becomes a state to do. Next, the adjustment separator shaft 7 is inserted through the through-hole 5 without being cut with the male screw attached from one end, and is passed through, and the adjustment separator shaft 7 is slid while temporarily tightening with the tightening screw 3. However, the distance between both molds is adjusted appropriately, and the male screw part at the other end is fixed to the other mold. Next, the tightening screw 3 is tightened to firmly connect and fix the adjusting separator shaft 7. In addition, the separator shaft connection fixture 100 of the second embodiment is inclined by about 90 ° laterally from the height direction of placement when necessary for securing the concrete thickness during concrete placement. It can be fixed with. Similarly, at the stage where the required number of separator shafts can be fixed by the separator shaft connecting fixture 100 and the distance between the molds can be kept constant, the concrete is finally placed to finish the construction. In the implementation of the second embodiment, the separator shaft connection fixture 100 is attached in advance to a necessary number of attachment objects such as a formwork, and then the adjustment separator shaft 7 having an appropriate distance is used together. The workability and work efficiency can be improved since the length can be adjusted and the connection can be fixed.

また、本第１の実施形態と同様に、双方の型枠間でセパレータ軸の寸法が合わないと気が付いたどちらかの端で、一方端が型枠パネルに接続固定されて長さが合わなくなった既存のセパレータ軸８Ａの他方端の雄ねじが付いたままの状態を本第２の実施形態のセパレータ軸接続固定金具１００の貫通孔５に差し込んで貫通させ当該セパレータ軸接続固定金具１００をスライドしながら、長さが合わない距離を適切に調整しアンカーセパレータ軸８Ｂの雄ねじ部を、他方端の型枠に接続固定し、締込ねじ３を締め付けてしっかり接続固定することにより、簡単に長さが合わない端の距離を補うことが可能となる。この様に、本第２の実施形態のセパレータ軸接続固定金具１００は、接続金具にアンカーセパレータ軸８Bとして、セパレータ軸が最初から付いている今までに無い新しい形体をしているため、わずかな距離で長さが合わなくても、本第２の実施形態のセパレータ軸接続固定金具１００を使用すれば当初用意していた既存のセパレータ軸を貫通孔５に刺し通せばアンカーセパレータ軸８Ｂが付いているので、新たなセパレータ軸を用意する必要が無くなり、アジャスターとしての機能を発揮し、直ちに双方の型枠パネルの連結工程にうつれ、作業工程も少なく取り付けも容易となる。以上のように、一本の既存のセパレータ軸８Ａだけをセパレータ軸調整金具１と強固な接続強度をみたし接続することが可能となったことで、前記説明のような今までに無い新しい使用の仕方と接続方法で、双方のセパレータ軸の連結が容易でトラブル解決と材料費削減や作業効率の向上が可能となる。 In addition, as in the first embodiment, one end that is noticed that the dimensions of the separator shaft do not match between the two molds, one end is connected and fixed to the mold panel, and the length does not match. Further, the state in which the external thread of the other end of the existing separator shaft 8A is still attached is inserted into the through hole 5 of the separator shaft connection fixing metal fitting 100 of the second embodiment, and the separator shaft connection fixing metal fitting 100 is slid. However, by adjusting the distance where the lengths do not match properly, the male threaded portion of the anchor separator shaft 8B is connected and fixed to the mold at the other end, and the fastening screw 3 is tightened to securely connect and fix the length. It is possible to compensate for the distance of the end where the two do not match. As described above, the separator shaft connection fixing metal fitting 100 according to the second embodiment has an unprecedented new shape in which the separator shaft is attached from the beginning as the anchor separator shaft 8B in the connection metal fitting. Even if the length does not match the distance, if the separator shaft connection fixing metal fitting 100 of the second embodiment is used, the anchor separator shaft 8B is attached if the existing separator shaft prepared at the beginning is inserted into the through hole 5. As a result, there is no need to prepare a new separator shaft, and the function as an adjuster is exhibited. As described above, it is possible to connect only one existing separator shaft 8A to the separator shaft adjusting bracket 1 with a strong connection strength. With this method and connection method, it is easy to connect both separator shafts, and it is possible to solve problems, reduce material costs and improve work efficiency.
