【0001】0001
この考案は、コンクリート型枠を所定の間隔に固定するセパレータ、更に詳し くは長さの調整が簡単に行なえるコンクリート型枠用のセパレータに関する。 This idea is based on a separator that fixes concrete formwork at predetermined intervals. This invention relates to a separator for concrete formwork whose length can be easily adjusted.
【0002】0002
コンクリート型枠を用いてコンクリート構造物を構築するには、図6に示すよ うに、両端にコーン1、1を取付けたセパレータ2を型枠3と3間に配置し、型 枠3、3の外面に突出するコーン1、1の螺軸4にカプラー5、5を螺合連結し 、型枠3、3を外面側から端太材で支持することにより、両型枠3、3を対向面 間にコーン1、1間の距離に等しい対向間隔を保持して固定し、型枠3、3間に コンクリートを打設することにより行なわれる。 To construct a concrete structure using concrete formwork, the steps shown in Figure 6 are as follows. Then, separator 2 with cones 1 and 1 attached to both ends is placed between formworks 3 and 3, and the Couplers 5, 5 are screwed and connected to the screw shafts 4 of the cones 1, 1 protruding from the outer surfaces of the frames 3, 3. , by supporting the formworks 3, 3 from the outside with thick timbers, both formworks 3, 3 are placed on opposite sides. Cones 1 and 1 are fixed with a facing interval equal to the distance between them, and between formworks 3 and 3. This is done by placing concrete.
【0003】 ところで、従来のセパレータ2は図6で示したように、一本の金属棒を用い、 両端にねじを設けてコーン1、1を螺合連結する構造になっている。0003 By the way, as shown in FIG. 6, the conventional separator 2 uses a single metal rod, It has a structure in which screws are provided at both ends and the cones 1, 1 are screwed together.
【0004】0004
上記のように従来のセパレータ2はその長さによって型枠3、3の支持間隔が 決まり、型枠の間隔の変化に対応するには長さの異なるセパレータを用意しなけ ればならないという問題がある。 As mentioned above, the conventional separator 2 has a support interval between the formworks 3 and 3 depending on its length. Separators of different lengths must be prepared to accommodate changes in formwork spacing. The problem is that it has to be done.
【0005】 また、長さの調整が可能なセパレータとして、二本の金属棒を用い、ターンバ ックル方式で両金属棒を結合して長さを変化させるものも提案されているが、長 さの調整範囲が極めて狭いうえに調整作業に手間がかかるという問題がある。[0005] In addition, two metal rods are used as separators whose lengths can be adjusted. It has also been proposed that the length can be changed by joining both metal rods using the buckle method, but There is a problem that the adjustment range for the height is extremely narrow and the adjustment work is time-consuming.
【0006】 そこでこの考案は、長さの調整が広範囲に行なえ、しかも調整作業が簡単なコ ンクリート型枠用のセパレータを提供することを課題としている。[0006] Therefore, this idea was developed to allow the length to be adjusted over a wide range, and the adjustment work is easy. Our goal is to provide separators for concrete formwork.
【0007】[0007]
上記のような課題を解決するため、この考案は、外周面にねじ形成した複数本 の螺軸と、前記螺軸を軸方向に平行する状態で結合する止め金具とからなり、止 め金具は、螺軸の重ね合わせた部分を外周面のねじが互に噛み合うように固定化 する構造になっている構成を採用したものである。 In order to solve the above problems, this idea uses multiple threads formed on the outer circumferential surface. The fastener consists of a screw shaft and a stopper that connects the screw shaft in parallel to the axial direction. The metal fitting fixes the overlapping parts of the screw shaft so that the screws on the outer circumferential surface engage with each other. This system adopts a structure that allows for

二本の螺軸を平行状態で重ね合わせ、この重ね合わせ部分を止め金具で結合す ると両螺軸は外周面のねじが互に噛み合い、結合一体化されてセパレータが組上 ると共に、両螺軸の重ね合わせ位置を選ぶことにより、長さの調整が簡単に行な える。 Lay the two screw shafts parallel to each other and connect the overlapping parts with a stopper. Then, the screws on the outer circumferential surfaces of both screw shafts engage with each other, and the separator is assembled into a single unit. In addition, the length can be easily adjusted by selecting the overlapping position of both screw shafts. I can do it.

以下、この考案の実施例を添付図面の図1乃至図5に基づいて説明する。 Embodiments of this invention will be described below with reference to FIGS. 1 to 5 of the accompanying drawings.
【0010】 図1のように、セパレータ11は、適当な長さの二本の螺軸12、13と、両 螺軸12、13を軸方向に平行する状態で結合する止め金具14からなり、セパ レータ11は螺軸12、13の端部にコーン15、15を螺合連結し、対向する 型枠16、16の内面をコーン15、15で支持することにより対向面間に所定 の間隔を保持すると共に、型枠16、16の外面に突出するコーン15、15の 螺軸17にカプラー18、18が連結されることになる。0010 As shown in FIG. 1, the separator 11 has two screw shafts 12 and 13 of appropriate length, and It consists of a stopper 14 that connects the screw shafts 12 and 13 in parallel to the axial direction, and is separated. In the rotor 11, cones 15, 15 are screwed and connected to the ends of screw shafts 12, 13, and are opposed to each other. By supporting the inner surfaces of the formworks 16, 16 with the cones 15, 15, a predetermined gap is formed between the opposing surfaces. of the cones 15, 15 protruding from the outer surfaces of the formworks 16, 16. Couplers 18, 18 are connected to the screw shaft 17.
【0011】 両螺軸12と13は、外周面の全長にわたって等しいピッチ及び傾斜方向のね じ12a、13aが形成され、平行状態で重ね合わせたとき互のねじ12a、1 3aが噛合うようになっている。[0011] Both screw shafts 12 and 13 have the same pitch and slope over the entire length of the outer circumferential surface. The same screws 12a, 13a are formed, and when stacked in parallel, the mutual screws 12a, 1 3a are designed to mesh.
【0012】 前記止め金具14は、図2乃至図5のように、重ね合わせた二本の螺軸12、 13に丁度外嵌する断面形状の角筒体21と、この角筒体21内に打込むクサビ 体22の組合せからなり、角筒体21には両側面の一方端部寄りの位置にクサビ 体22の打込み孔23、23が設けられている。0012 As shown in FIGS. 2 to 5, the stopper 14 has two overlapping screw shafts 12, 13, and a wedge driven into this square cylinder 21. It consists of a combination of bodies 22, and the square cylinder body 21 has a wedge near one end of both sides. Driving holes 23, 23 in the body 22 are provided.
【0013】 この考案のセパレータは上記のような構成であり、二本の螺軸12、13を両 端のコーン15と15の間隔が型枠16、16の支持間隔になるよう平行状に重 ね合わせ、両螺軸12と13の重ね合わせ部分に角筒体21を外嵌挿し、図2と 図3のように角筒体21内の一方端部と一方螺軸12の隙間に対してクサビ体2 2を打込み、両螺軸12と13の重なり部分を圧着させる。[0013] The separator of this invention has the above-mentioned configuration, and the two screw shafts 12 and 13 are connected to each other. The cones 15 at the ends are stacked in parallel so that the distance between them is the support distance between the formworks 16 and 16. After screwing together, the square cylinder body 21 is externally inserted into the overlapping part of both screw shafts 12 and 13, and as shown in FIG. As shown in FIG. 3, the wedge body 2 2 to press the overlapping portions of both screw shafts 12 and 13 together.
【0014】 両螺軸12と13は、重なり合う部分のねじ12aと13aが噛み合った状態 で圧着し、結合一体化することによってセパレータ11は組上がることになる。[0014] Both screw shafts 12 and 13 are in a state where the overlapping parts of screws 12a and 13a are engaged. The separator 11 is assembled by crimping and joining together.
【0015】 両螺軸12と13の結合において、図2と図3はクサビ体22を螺軸12、1 3の軸方向から打込む例を示したが、スペース的に上記軸方向からの打込みが困 難な場合は、図4の如く、角筒体21に設けた窓孔23、23にクサビ体22を 一方螺軸12と交差する方向から打込み、両螺軸12と13を結合するようにし てもよい。[0015] 2 and 3 show that the wedge body 22 is connected to the screw shafts 12 and 13. Although we have shown an example of driving from the axial direction of 3, it is difficult to drive from the above axial direction due to space constraints. If this is difficult, insert the wedge body 22 into the window holes 23, 23 provided in the rectangular tube body 21, as shown in Fig. 4. On the other hand, drive from the direction intersecting the screw shaft 12 so as to connect both screw shafts 12 and 13. It's okay.
【0016】 このように、セパレータ11は、両螺軸12と13の重ね合わせ量を選ぶこと によりその長さを無段階的に調整することができ、型枠16、16の間隔の変化 に対して広範囲に対応できると共に、止め金具14はクサビ体22の打込み式で あるので、作業が簡単であり、螺軸12と13の重ね合わせ部分は互のねじ12 a、13aが噛み合った状態で結合されるため、荷重に対する十分な強度が得ら れることになる。[0016] In this way, the separator 11 can be created by selecting the amount of overlapping of both screw shafts 12 and 13. The length can be adjusted steplessly by changing the interval between the formworks 16, 16. It can be applied to a wide range of situations, and the stopper 14 is a wedge body 22 driven type. The overlapping part of the screw shafts 12 and 13 is the same as the other screw 12. Since a and 13a are connected in a meshed state, sufficient strength against the load can be obtained. It will be.
【0017】 なお、両螺軸12、13の重なり部分が長い場合、その複数個所を止め金具1 4で結合してもよいと共に、止め金具14は図示のようなクサビ体22の打込み 構造に限定されるものではなく、例えばボルトの締付けにより両螺軸12、13 を圧着させるようにしてもよい。[0017] In addition, if the overlapping parts of both screw shafts 12 and 13 are long, the multiple parts should be fixed with the stopper 1. 4, and the stopper 14 can be connected by driving a wedge body 22 as shown in the figure. It is not limited to the structure, but for example, both screw shafts 12 and 13 can be tightened by tightening bolts. It may also be made to be crimped.
【0018】 また、両螺軸12、13の端部は共にコーン15、15を取付けて型枠16、 16を支持するようにしたが、例えば端部にワッシャを取付けたり、一方螺軸の 端部を鋼矢板等に溶接固定するようにしてもよい。[0018] In addition, cones 15, 15 are attached to the ends of both screw shafts 12, 13, and the formwork 16, 16, but for example, by attaching a washer to the end, or by attaching a washer to the end of the screw shaft. The end portion may be fixed by welding to a steel sheet pile or the like.
【0019】 更に長尺のセパレータを構成する場合、三本以上の螺軸を止め金具で結合して 形成するようにしてもよい。[0019] When constructing a longer separator, three or more screw shafts can be connected with a stopper. It may also be formed.
【0020】[0020]
以上のように、この考案によると、複数本の螺軸を平行状態に重ね合わせ、こ の重ね合わせ部分を止め金具でロックするようにしたので、螺軸は重なり部分の ねじが互に噛み合い、強固な結合状態が得られると共に、螺軸の重なり量を選ぶ ことにより長さの調整が自由に行なえ、コンクリート型枠の間隔の変化に広範囲 に対応できる。 As described above, according to this invention, multiple screw shafts are superimposed in parallel, and this The overlapping part of the screws is locked with a stopper, so the screw shaft is attached to the overlapping part. The screws mesh with each other to create a strong connection, and the amount of overlap between the screw shafts is selected. This allows the length to be freely adjusted, allowing for a wide range of changes in the spacing of concrete formwork. Can correspond to
