Description

本発明はパイプ取り付け用クランプに関するものである。 The present invention relates to a pipe mounting clamp.

建築資材を予め保管しておくための資材テントや、野外イベントなどで設置される仮設ステージなど仮設建物の組立式枠体や建設工事現場における足場などに単管パイプ（以下、「パイプ」と記す。）が広く用いられている。そしてパイプ同士を接続固定する部材として種々のクランプが提案され市販もされている（例えば特許文献１〜３など）。 Single pipes (hereinafter referred to as "pipes") are used for assembly-type frames of temporary buildings such as material tents for storing building materials in advance, temporary stages installed at outdoor events, and scaffolding at construction sites. .) Is widely used. Various clamps have been proposed and commercially available as members for connecting and fixing pipes to each other (for example, Patent Documents 1 to 3).

図１１に、従来のクランプの一例を示す斜視図に示す。この図に示すクランプＣＬは、２本のパイプＰａ，Ｐｂを直交状態に接続固定するものであって、２つのクランプ部Ｃａとクランプ部Ｃｂの本体の底部が直交方向に連結されている。２つのクランプ部Ｃａ，Ｃｂは同一の構造を有し、略Ｌ字形状で内周面が円弧状の凹部４１１とされたクランプ本体４１と、クランプ本体４１の一方端に回動自在に取り付けられ、内周面が円弧状の凹部４２１とされた蓋体４２と、クランプ本体４１の他方端に回動自在に取り付けられた締結ボルト４３とを備え、蓋体４２の他方端には締結ボルト４３の先端部分を係合しナット４４で締め付けるためのナット受け部４２２が形成されている。 FIG. 11 is a perspective view showing an example of a conventional clamp. The clamp CL shown in this figure connects and fixes two pipes Pa and Pb in an orthogonal state, and the two clamp portions Ca and the bottom portion of the main body of the clamp portion Cb are connected in the orthogonal direction. The two clamp portions Ca and Cb have the same structure, and are rotatably attached to one end of the clamp main body 41 having a substantially L-shaped inner peripheral surface having an arc-shaped recess 411 and the clamp main body 41. A lid body 42 having an arcuate concave portion 421 on the inner peripheral surface and a fastening bolt 43 rotatably attached to the other end of the clamp body 41 are provided, and a fastening bolt 43 is provided at the other end of the lid body 42. A nut receiving portion 422 for engaging and tightening the tip portion of the nut 44 is formed.

このような構成のクランプＣＬでは、クランプ本体４１の凹部４１１と蓋体４２の凹部４２１とでパイプＰａ，Ｐｂを外周を囲み込み締結ボルトＢとナットＮとで締め付けることでパイプＰａ，Ｐｂを直交状態に固定する。 In the clamp CL having such a configuration, the pipes Pa and Pb are surrounded by the recess 411 of the clamp body 41 and the recess 421 of the lid 42, and the pipes Pa and Pb are orthogonal to each other by tightening the fastening bolts B and nuts N. Fix to state.

特開平０８−１２８１９４号公報Japanese Unexamined Patent Publication No. 08-128194 特開平１０−１０２７６５号公報Japanese Unexamined Patent Publication No. 10-102765 特開２０００−２６６０１４号公報Japanese Unexamined Patent Publication No. 2000-266014

このような構成の従来のクランプＣＬによれば２本のパイプＰａ，Ｐｂの接続固定は確実に行うことはできるが、クランプＣＬを用いてパイプＰａ，Ｐｂを接続固定して組み立てられた組立体では、パイプＰａ，Ｐｂの接続部分はクランプ部分４１，４２がパイプＰａ，Ｐｂの外周面から外方に突出しているため、例えば、複数のパイプがその外周面が同一平面に接するように配置され、当該複数のパイプ上に平板が取り付けられるとき、平板の表面のクランプ部分に対応する位置に凸部が不可避的に生じる。これを避けるためにはクランプに当たる部分を切り欠いて平板がクランプに当接しないようにする必要がある。 According to the conventional clamp CL having such a configuration, the connection and fixing of the two pipes Pa and Pb can be reliably performed, but the assembly assembled by connecting and fixing the pipes Pa and Pb using the clamp CL. Then, in the connecting portion of the pipes Pa and Pb, since the clamp portions 41 and 42 project outward from the outer peripheral surface of the pipes Pa and Pb, for example, a plurality of pipes are arranged so that the outer peripheral surfaces are in contact with the same plane. When the flat plate is mounted on the plurality of pipes, a convex portion is inevitably generated at a position corresponding to the clamp portion on the surface of the flat plate. In order to avoid this, it is necessary to cut out the portion that hits the clamp so that the flat plate does not come into contact with the clamp.

また、従来のクランプは部品点数が多くまた重いためパイプの接続組立作業には労力を要していた。 In addition, since the conventional clamp has a large number of parts and is heavy, it takes a lot of labor to connect and assemble the pipe.

本発明はこのような従来の問題に鑑みてなされたものであり、その目的は、パイプの接続部分においてパイプの一部を覆うことなく２本のパイプを直交状態に接続固定できるクランプを提供することにある。 The present invention has been made in view of such conventional problems, and an object of the present invention is to provide a clamp capable of connecting and fixing two pipes in an orthogonal state without covering a part of the pipes at a connecting portion of the pipes. There is.

また本発明の他の目的は、従来のクランプに比べて軽量化することにある。 Another object of the present invention is to reduce the weight as compared with the conventional clamp.

前記目的を達成する本発明に係るパイプ用のクランプは、２本のパイプを直交状態で接続固定するクランプであって、離隔対向して配置された一対の挟持板と、前記一対の挟持板の対向する一方側部を互いに近づく方向に締め付けるネジ式締結部材とを備え、前記一対の挟持板の前記一方側部と反対側の他方側部の各々に、一方のパイプが挿通可能で、周縁開口部が前記一方のパイプの外径よりも短く、前記一方のパイプが挿通されると前記一方のパイプの一部が外方に突出する切欠き部が形成され、前記切欠き部と前記ネジ式締結部材との間の距離が、前記一対の挟持板の間で且つ前記切欠き部と前記ネジ式締結部材との間に他方のパイプが挿通可能な距離とされ、前記切欠き部に前記一方のパイプを挿通し、前記一対の挟持板の間で且つ前記切欠き部と前記ネジ式締結部材との間に他方のパイプを挿通し、前記ネジ式締結部材を締め付けることによって前記一方のパイプと前記他方のパイプとを直交状態に接続固定することを特徴とする。 The pipe clamp according to the present invention that achieves the above object is a clamp that connects and fixes two pipes in an orthogonal state, and is a pair of holding plates arranged so as to be separated from each other and the pair of holding plates. It is provided with a screw type fastening member that tightens one side portion facing each other in a direction approaching each other, and one pipe can be inserted into each of the other side portion on the opposite side to the one side portion of the pair of holding plates, and a peripheral opening is provided. The portion is shorter than the outer diameter of the one pipe, and when the one pipe is inserted, a notch portion is formed in which a part of the one pipe protrudes outward, and the notch portion and the screw type The distance between the fastening members is such that the other pipe can be inserted between the pair of holding plates and between the notch and the screw type fastening member, and the one pipe is inserted into the notch. The other pipe is inserted between the pair of holding plates and between the notch and the screw type fastening member, and the screw type fastening member is tightened to tighten the one pipe and the other pipe. It is characterized in that and is connected and fixed in an orthogonal state.

前記構成のパイプ用クランプにおいて、前記切欠き部と前記ネジ式締結部材との間の距離が、前記他方のパイプの外径と略同一である構成とするのが好ましい。 In the pipe clamp having the above configuration, it is preferable that the distance between the notch and the screw type fastening member is substantially the same as the outer diameter of the other pipe.

前記構成のパイプ用クランプにおいて、前記ネジ式締結部材が締結ボルトとナットとを有し、前記一対の挟持板は一方側部の対向する位置に貫通孔を有し、前記締結ボルトが前記貫通孔の各々を挿通し、前記締結ボルトの先端にナットが螺合されることによって前記一対の挟持板が互いに近づく方向に締め付けられる構成としてもよい。 In the pipe clamp having the above configuration, the screw type fastening member has a fastening bolt and a nut, the pair of holding plates have through holes at opposite positions on one side, and the fastening bolt has the through holes. The pair of holding plates may be tightened in a direction approaching each other by inserting each of the above and screwing a nut into the tip of the fastening bolt.

前記構成のパイプ用クランプにおいて、前記一対の挟持板が長方形状で、前記一対の挟持板の長手方向一方側にネジ式締結部材が設けられ長手方向他方側の側縁に前記切欠き部の周縁開口部が形成されている構成としてもよい。 In the pipe clamp having the above configuration, the pair of holding plates are rectangular, and a screw type fastening member is provided on one side in the longitudinal direction of the pair of holding plates, and the peripheral edge of the notch is provided on the side edge on the other side in the longitudinal direction. The configuration may be such that an opening is formed.

ここで、前記一対の挟持板の各々が、長手方向一方側の側縁から前記切欠き部に至る部分において分割及び合体可能である構成としてもよい。 Here, each of the pair of holding plates may be configured to be able to be divided and combined at a portion extending from a side edge on one side in the longitudinal direction to the notch portion.

そして、二分割された挟持板の一方の分割片に形成された第１の凹凸部と、他方の分割片に形成された第２の凹凸部とが係合することによって２つの分離片が合体し、第１の凹凸部と第２の凹凸部とは前記挟持板の厚み方向からのみ挿脱可能である構成としてもよい。 Then, the two separated pieces are united by engaging the first uneven portion formed on one divided piece of the two-divided holding plate and the second uneven portion formed on the other divided piece. However, the first concavo-convex portion and the second concavo-convex portion may be configured to be removable only from the thickness direction of the holding plate.

また前記構成のパイプ用クランプにおいて、前記一対の挟持板における所定方向一方側にネジ式締結部材が設けられ、所定方向他方側で所定方向に交差する方向一方側の側縁に前記切欠き部の周縁開口部が形成されている構成としてもよい。 Further, in the pipe clamp having the above configuration, a screw type fastening member is provided on one side in a predetermined direction of the pair of holding plates, and the notch portion is provided on one side edge in a direction intersecting the predetermined direction on the other side in the predetermined direction. A peripheral opening may be formed.

ここで、水平方向一方側にネジ式締結部材が設けられ、水平方向他方側で鉛直方向上側の側縁に前記切欠き部の周縁開口部が形成され、鉛直方向最も上側のネジ式締結部材の軸中心が、前記切欠き部の軸中心よりも鉛直方向上方に位置している構成としてもよい。 Here, a screw type fastening member is provided on one side in the horizontal direction, and a peripheral opening of the notch portion is formed on the upper side edge in the vertical direction on the other side in the horizontal direction. The shaft center may be located above the shaft center of the notch portion in the vertical direction.

本発明に係るパイプ用クランプでは、パイプの接続部分においてパイプの一部を覆うことなく２本のパイプを直交状態に接続固定できる。これにより、クランプで覆われていないパイプの部分に接触するように板状体を取り付けることで、クランプに起因する凸部が板状体に生じることがなく、また従来のようにクランプとの当接を避けるための切欠きを板状体に形成する必要もなくなる。 In the pipe clamp according to the present invention, two pipes can be connected and fixed in an orthogonal state without covering a part of the pipe at the connecting portion of the pipe. As a result, by attaching the plate-shaped body so as to come into contact with the portion of the pipe that is not covered by the clamp, the convex portion due to the clamp does not occur on the plate-shaped body, and the contact with the clamp is performed as in the conventional case. It is no longer necessary to form a notch in the plate-like body to avoid contact.

また本発明に係るパイプ用クランプは、従来のクランプに比べて部品点数が少なく軽量化が可能となる。 Further, the pipe clamp according to the present invention has a smaller number of parts and can be reduced in weight as compared with the conventional clamp.

以下、本発明に係るパイプ用クランプ（以下「クランプ」と記すことがある。）について図に基づいて説明するが本発明はこれらの実施形態に何ら限定されるものではない。 Hereinafter, the pipe clamp according to the present invention (hereinafter, may be referred to as “clamp”) will be described with reference to the drawings, but the present invention is not limited to these embodiments.

（第１実施形態）
図１に、第１実施形態に係るクランプＣ１の正面図及び右側面図を示す。図１のクランプＣ１は、一対の長方形状の挟持板１ａ，１ｂと、挟持板１ａ，１ｂを連結するボルトＢと、ナットＮとから構成される。本実施形態ではボルトＢとナットＮがネジ式締結部材を構成する。 (First Embodiment)
FIG. 1 shows a front view and a right side view of the clamp C1 according to the first embodiment. The clamp C1 of FIG. 1 is composed of a pair of rectangular holding plates 1a and 1b, a bolt B connecting the holding plates 1a and 1b, and a nut N. In this embodiment, the bolt B and the nut N form a screw type fastening member.

挟持板１ａ，１ｂは同一形状であるので、代表して挟持板１ａについて説明する。挟持板１ａは長方形状の板部材であって四隅は丸み処理されている。挟持板１ａの上下方向（長手方向）上側の側縁の前後方向（短手方向）中央部には円弧状の切欠き部１３が形成され、また挟持板１ａの下側の前後方向中央部にはボルトＢの軸部が挿通可能な貫通孔１４が形成されている。切欠き部１３の半径はパイプＰ１（図２に図示）の半径と同一又は若干大きく、切欠き部１３の周縁開口部１１の幅ＤはパイプＰ１の直径よりも短く設定されている。また切欠き部１３の下端から貫通孔１４の上端すなわちボルトＢの軸部の上端までの距離ＬはパイプＰ２（図２に図示）の直径と同一又は若干大きく設定されている。 Since the holding plates 1a and 1b have the same shape, the holding plate 1a will be described as a representative. The holding plate 1a is a rectangular plate member, and the four corners are rounded. An arcuate notch 13 is formed at the center of the upper side edge of the holding plate 1a in the vertical direction (longitudinal direction) in the front-rear direction (short direction), and in the central part of the lower front-rear direction of the holding plate 1a. Is formed with a through hole 14 through which the shaft portion of the bolt B can be inserted. The radius of the notch 13 is the same as or slightly larger than the radius of the pipe P1 (shown in FIG. 2), and the width D of the peripheral opening 11 of the notch 13 is set shorter than the diameter of the pipe P1. Further, the distance L from the lower end of the notch portion 13 to the upper end of the through hole 14, that is, the upper end of the shaft portion of the bolt B is set to be the same as or slightly larger than the diameter of the pipe P2 (shown in FIG. 2).

クランプＣ１は、離隔対向した挟持板１ａ，１ｂに形成された貫通孔１４にボルトＢの軸部が挿通され、ボルトＢの軸部の先端にナットＮが螺合されて組立られる。 The clamp C1 is assembled by inserting the shaft portion of the bolt B into the through holes 14 formed in the holding plates 1a and 1b facing each other and screwing the nut N to the tip of the shaft portion of the bolt B.

図２に示すように、このような構成のクランプＣ１によってパイプＰ１とパイプＰ２とを接続固定する場合、まず、離隔対向した挟持板１ａ，１ｂの切欠き部１３にパイプＰ１が左右方向から挿通される。次いで、パイプＰ２が、パイプＰ１の下端とボルトＢの軸部の上端との間に前後方向から挿通される。この状態ではクランプＣ１はパイプＰ１，Ｐ２に対して相対移動可能であり、パイプＰ１，Ｐ２の所定の固定位置に移動設置される。なお、パイプＰ１とパイプＰ２とのクランプＣ１への挿通順序は逆にしても勿論かまわない。 As shown in FIG. 2, when connecting and fixing the pipe P1 and the pipe P2 by the clamp C1 having such a configuration, first, the pipe P1 is inserted into the notch 13 of the holding plates 1a and 1b facing each other from the left and right directions. Will be done. Next, the pipe P2 is inserted between the lower end of the pipe P1 and the upper end of the shaft portion of the bolt B from the front-rear direction. In this state, the clamp C1 can move relative to the pipes P1 and P2, and is moved and installed at a predetermined fixed position of the pipes P1 and P2. Of course, the insertion order of the pipe P1 and the pipe P2 to the clamp C1 may be reversed.

次いで、クランプＣ１のボルトＢに対してナットＮが相対的に締め付けられる。これによって、ボルトＢの頭部とナットＮとの間隔が狭くなり、一対の挟持板１ａ，１ｂの下側部は接近する方向に移動し、一対の挟持板１ａ，１ｂは“てこの原理”によってパイプＰ１とパイプＰ２とを挟持し固定する。すなわち、一対の挟持板１ａ，１ｂとボルトＢ、ナットＮとの接触部が力点、一対の挟持板１ａ，１ｂとパイプＰ２との接触部が支点、一対の挟持板１ａ，１ｂの切欠き部１３とパイプＰ１との接触部が作用点となって、一対の挟持板１ａ，１ｂの下側部が接近する方向に移動することによって、一対の挟持板１ａ，１ｂの上側部が互いに離れる方向に移動して、切欠き部１３の周縁開口部１１の両端及び切欠き部１３の内周面がパイプＰ１の表面を摺動してパイプＰ１の表面に圧接しパイプＰ１は一対の挟持板１ａ，１ｂによって固定される。また同時に、パイプＰ２は挟持板１ａ，１ｂによる圧接挟持によって固定される。加えて、挟持板１ａ，１ｂによってパイプＰ１に対して下方向に力が加わり、パイプＰ１とボルトＢの軸部との間でパイプＰ２は挟持され固定され、その反作用としてパイプＰ２と一対の挟持板１ａ，１ｂの切欠き部１３の内周面との間でパイプＰ１は挟持され固定される。 Next, the nut N is tightened relative to the bolt B of the clamp C1. As a result, the distance between the head of the bolt B and the nut N is narrowed, the lower portions of the pair of holding plates 1a and 1b move in the approaching direction, and the pair of holding plates 1a and 1b are "lever principle". The pipe P1 and the pipe P2 are sandwiched and fixed by the pipe P1 and the pipe P2. That is, the contact portion between the pair of holding plates 1a and 1b and the bolt B and the nut N is the force point, the contact portion between the pair of holding plates 1a and 1b and the pipe P2 is the fulcrum, and the notch portion of the pair of holding plates 1a and 1b. The contact portion between the 13 and the pipe P1 serves as an action point, and the lower portions of the pair of holding plates 1a and 1b move in the approaching direction, so that the upper portions of the pair of holding plates 1a and 1b are separated from each other. The both ends of the peripheral edge opening 11 of the notch 13 and the inner peripheral surface of the notch 13 slide on the surface of the pipe P1 and press-contact with the surface of the pipe P1, and the pipe P1 is a pair of holding plates 1a. , 1b. At the same time, the pipe P2 is fixed by pressure welding and sandwiching by the sandwiching plates 1a and 1b. In addition, a downward force is applied to the pipe P1 by the holding plates 1a and 1b, and the pipe P2 is sandwiched and fixed between the pipe P1 and the shaft portion of the bolt B. The pipe P1 is sandwiched and fixed between the inner peripheral surface of the notch 13 of the plates 1a and 1b.

このようなクランプＣ１によるパイプＰ１，Ｐ２の接続固定によれば、切欠き部１３から上方にパイプＰ１の一部が突出した状態でパイプＰ１とパイプＰ２とが直交に接続固定されるので、例えば図３に示すように、複数本のパイプＰ１が共通のパイプＰ２上に前後方向に所定間隔でその上端が同一平面上に位置するようにクランプＣ１で接続固定されると、クランプＣ１に起因する凸部を生じさせることなく複数本のパイプＰ１上に平板ＰＬを設置することが可能となる。 According to the connection and fixing of the pipes P1 and P2 by the clamp C1, the pipe P1 and the pipe P2 are connected and fixed orthogonally with a part of the pipe P1 protruding upward from the notch portion 13, for example. As shown in FIG. 3, when a plurality of pipes P1 are connected and fixed on a common pipe P2 with a clamp C1 so that their upper ends are located on the same plane at predetermined intervals in the front-rear direction, the cause is caused by the clamp C1. It is possible to install the flat plate PL on a plurality of pipes P1 without causing a convex portion.

（変形例）
図４にクランプＣ１の変形例を示す。この図に示すクランプＣ２は、図１に示したクランプＣ１と基本的な構成は同一であるが、クランプＣ２を構成する一対の挟持体１ｃ，１ｄの各々が２つの分割片１２ａ，１２ｂに分離・合体可能である点が相違する。以下、挟持板１ｃ，１ｄについて説明するが、挟持体１ａ，１ｂと同一の構成については説明を省略し挟持体１ａ，１ｂと異なる構成についてのみ説明する。 (Modification example)
FIG. 4 shows a modified example of the clamp C1. The clamp C2 shown in this figure has the same basic configuration as the clamp C1 shown in FIG. 1, but each of the pair of sandwiching bodies 1c and 1d constituting the clamp C2 is separated into two split pieces 12a and 12b.・ The difference is that they can be combined. Hereinafter, the sandwiching plates 1c and 1d will be described, but the same configuration as the sandwiching bodies 1a and 1b will be omitted and only the configuration different from the sandwiching bodies 1a and 1b will be described.

クランプＣ２を構成する挟持体１ｃ，１ｄは、下側縁の前後方向（短手方向）中央から円弧状の切欠き部１３の下部に至る波形状の分割ラインＬＮで２つの分割片１２ａ，１２ｂに分割及び合体可能とされている。分割片１２ａ及び分割片１２ｂの分割ラインＬＮにはそれぞれ第１の凹凸部１５及び第２の凹凸部１６が形成されている。第１の凹凸部１５及び第２の凹凸部１６とは同一で円弧形状の凸部１５１と凹部１６１とが交互に連続して形成されてなる。図４の楕円で囲まれた拡大図に示すように、凸部１５１は円弧状の頭部１５１ａと首部１５１ｂとを有し、頭部１５１ａの直径Ｄ１は首部１５１ｂの最小幅Ｄ２よりも長く設定されている。また、凹部１６１は凸部１５１と同一形状を有している。 The sandwiching bodies 1c and 1d constituting the clamp C2 are two dividing pieces 12a and 12b along a wave-shaped dividing line LN extending from the center of the lower edge in the front-rear direction (short direction) to the lower part of the arc-shaped notch 13. It is possible to divide and combine into. A first concavo-convex portion 15 and a second concavo-convex portion 16 are formed on the division line LN of the division piece 12a and the division piece 12b, respectively. The first concavo-convex portion 15 and the second concavo-convex portion 16 are the same, and the arc-shaped convex portion 151 and the concave portion 161 are alternately and continuously formed. As shown in the enlarged view surrounded by the ellipse of FIG. 4, the convex portion 151 has an arcuate head portion 151a and a neck portion 151b, and the diameter D1 of the head portion 151a is set longer than the minimum width D2 of the neck portion 151b. Has been done. Further, the concave portion 161 has the same shape as the convex portion 151.

分割片１２ａ，１２ｂとは、第１の凹凸部１５の凸部１５１及び凹部１６１が、第２の凹凸部１６の凹部１６１及び凸部１５１にそれぞれ係入することによって合体する。なお、凸部１５１と凹部１６１との係入は挟持体１ｃの厚み方向（図４において紙面垂直方向）からのみ係入可能である。換言すると、合体した分割片１２ａ，１２ｂは図４において前後方向で互いに離れる方向に外力が加わっても分離することはない。 The divided pieces 12a and 12b are united by engaging the convex portion 151 and the concave portion 161 of the first uneven portion 15 with the concave portion 161 and the convex portion 151 of the second uneven portion 16, respectively. The convex portion 151 and the concave portion 161 can be engaged only from the thickness direction of the sandwiching body 1c (the direction perpendicular to the paper surface in FIG. 4). In other words, the combined split pieces 12a and 12b do not separate in FIG. 4 even if an external force is applied in the direction away from each other in the front-rear direction.

このような分割合体可能な挟持板１ｃ，１ｄからなるクランプＣ２によれば、予め切欠き部１３にパイプを挿通させていない場合であっても、挟持板１ｃ，１ｄを分割片１２ａ，１２ｂに分割して切欠き部１３を構成する内周部でパイプを挟み込み、次いで分割片１２ａ，１２ｂを合体させることによりパイプの所望位置に挟持板１ｃ，１ｄを後から取り付けることが可能となる。 According to the clamp C2 composed of the holding plates 1c and 1d which can be divided into different parts, the holding plates 1c and 1d are divided into the divided pieces 12a and 12b even when the pipe is not inserted through the notch 13 in advance. By sandwiching the pipe between the inner peripheral portions that are divided and forming the notch portion 13 and then combining the divided pieces 12a and 12b, the holding plates 1c and 1d can be attached to the desired positions of the pipe later.

図４に示した実施形態例では凸部及び凹部はいずれも円弧形状であったが、これに限定されるものではなく、凸部と凹部とは同一形状であって挟持板の厚み方向からのみ挿脱可能な形状であればよい。 In the embodiment shown in FIG. 4, both the convex portion and the concave portion have an arc shape, but the present invention is not limited to this, and the convex portion and the concave portion have the same shape and only from the thickness direction of the holding plate. Any shape may be used as long as it can be inserted and removed.

（第２実施形態）
図５に、第２実施形態に係るクランプＣ３の正面図及び右側面図を示す。図５のクランプＣ３は、一対の長方形状の挟持板２ａ，２ｂと、挟持板２ａ，２ｂを連結する２本のボルトＢ１，Ｂ２と、２個のナットＮとから構成される。この実施形態では、２本のボルトＢ１，Ｂ２と、２個のナットＮとがネジ式締結部材を構成する。 (Second Embodiment)
FIG. 5 shows a front view and a right side view of the clamp C3 according to the second embodiment. The clamp C3 of FIG. 5 is composed of a pair of rectangular holding plates 2a and 2b, two bolts B1 and B2 connecting the holding plates 2a and 2b, and two nuts N. In this embodiment, two bolts B1 and B2 and two nuts N form a screw type fastening member.

挟持板２ａ，２ｂは同一形状であるので、代表して挟持板２ａについて説明する。図５（ｂ）に示されるように、挟持板２ａは、直線状で略平行な前側縁２１１と後側縁２１２と、前後方向途中部において前側が後側より下がる段差２１３ａを有する上側縁２１３と、前後方向途中部において前側から後側に向かって上方に傾斜した傾斜部２１４ａを有する下側縁２１４とを有する。挟持板２ａの後側部には上下方向に所定間隔隔てて、ボルトＢ１，Ｂ２の軸部が挿通可能な大きさの２つの貫通孔２４が形成されている。また、上側縁２１３の段差２１３ａよりも前方には円弧状の切欠き部２３が形成されている。切欠き部２３の半径はパイプＰ１の半径と同一又は若干大きく、切欠き部２３の周縁開口部２１の幅ＤはパイプＰ１の直径よりも短く設定されている。また切欠き部２３の後端から貫通孔２４の前端すなわちボルトＢ１，Ｂ２の軸部の前端までの距離ＬはパイプＰ３の直径と同一又は若干大きく設定されている。 Since the holding plates 2a and 2b have the same shape, the holding plate 2a will be described as a representative. As shown in FIG. 5B, the holding plate 2a has an upper edge 213 having a linear and substantially parallel front side edge 211 and a rear side edge 212, and a step 213a in which the front side is lower than the rear side in the middle of the front-rear direction. And a lower edge 214 having an inclined portion 214a inclined upward from the front side to the rear side in the middle portion in the front-rear direction. Two through holes 24 having a size through which the shaft portions of the bolts B1 and B2 can be inserted are formed in the rear side portion of the holding plate 2a at predetermined intervals in the vertical direction. Further, an arc-shaped notch 23 is formed in front of the step 213a of the upper edge 213. The radius of the notch 23 is the same as or slightly larger than the radius of the pipe P1, and the width D of the peripheral opening 21 of the notch 23 is set shorter than the diameter of the pipe P1. Further, the distance L from the rear end of the notch 23 to the front end of the through hole 24, that is, the front end of the shaft portion of the bolts B1 and B2 is set to be the same as or slightly larger than the diameter of the pipe P3.

なお、クランプＣ３を構成する挟持板２ａ，２ｂの上端縁２１３に段差２１３ａが形成されているのは、ボルトＢ１の軸中心Ｏ２が切欠き部２３の軸中心Ｏ１よりも鉛直方向上方に位置するようにするためである。図６に示すように、ボルトＢ１の軸中心Ｏ２が、切欠き部２３の軸中心Ｏ１よりも鉛直方向上方に位置することによって、垂設されたパイプＰ３にクランプＣ３によってパイプＰ１を水平に取り付ける際に、パイプＰ１及びクランプＣ３の自重によってポルトＢ１とパイプＰ３との接触部を中心として図６（ｂ）において反時計回りの回転モーメントがクランプＣ３に生じてパイプＰ１とパイプＰ３とが圧接するので、クランプＣ３がパイプＰ３に沿って下方にずり落ちることがパイプＰ１とパイプＰ３との摩擦抵抗によって抑制されクランプＣ３のパイプＰ３への接続固定作業が容易になる。もちろんこのような作用効果を必要としない場合には挟持板２ａ，２ｂの上端縁２１３は直線状としてもよい。 The step 213a is formed on the upper end edges 213 of the holding plates 2a and 2b constituting the clamp C3 so that the shaft center O 2 of the bolt B1 is vertically above the shaft center O 1 of the notch 23. This is to ensure that it is located. As shown in FIG. 6, the shaft center O 2 of the bolt B1 is located vertically above the shaft center O 1 of the notch 23, so that the pipe P1 is horizontal to the vertically installed pipe P3 by the clamp C3. Due to the weight of the pipe P1 and the clamp C3, a counterclockwise rotational moment is generated in the clamp C3 around the contact portion between the port B1 and the pipe P3 in FIG. Since the clamp C3 is pressure-welded, the fact that the clamp C3 slides downward along the pipe P3 is suppressed by the frictional resistance between the pipe P1 and the pipe P3, and the connection and fixing work of the clamp C3 to the pipe P3 becomes easy. Of course, when such an action effect is not required, the upper end edges 213 of the holding plates 2a and 2b may be linear.

また、挟持板２ａ，２ｂの下端縁２１４に傾斜部２１４ａが形成されているのは、クランプＣ３の下側に別のクランプを取り付けて他のパイプを接続固定する際に、クランプＣ３と当該別のクランプとを近設可能とするためであり、下端縁２１４に傾斜部２１４ａを設けることなく直線状としても構わない。 Further, the reason why the inclined portion 214a is formed on the lower end edges 214 of the holding plates 2a and 2b is that when another clamp is attached to the lower side of the clamp C3 and another pipe is connected and fixed, the clamp C3 and the other are different. This is because the clamp of the above can be installed close to the clamp, and the lower end edge 214 may be linear without providing the inclined portion 214a.

クランプＣ３は、離隔対向した挟持板２ａ，２ｂに形成された貫通孔２４の各々にボルトＢの軸部が挿通され、ボルトＢの軸部の先端にナットＮが螺合されて組立られる。 The clamp C3 is assembled by inserting the shaft portion of the bolt B into each of the through holes 24 formed in the holding plates 2a and 2b facing each other and screwing the nut N to the tip of the shaft portion of the bolt B.

図６に示すように、このような構成のクランプＣ３によってパイプＰ１とパイプＰ３とを接続固定する場合、まず、離隔対向した挟持板２ａ，２ｂの切欠き部２３にパイプＰ１が左右方向から挿通される。次いで、パイプＰ３が、パイプＰ１の後端とボルトＢの軸部の前端との間に上下方向から挿通される。この状態ではクランプＣ３はパイプＰ１，Ｐ３に対して相対移動可能であり、パイプＰ１，Ｐ３の所定の固定位置に移動設置される。 As shown in FIG. 6, when connecting and fixing the pipe P1 and the pipe P3 by the clamp C3 having such a configuration, first, the pipe P1 is inserted into the notch 23 of the holding plates 2a and 2b facing each other from the left and right directions. Will be done. Next, the pipe P3 is inserted between the rear end of the pipe P1 and the front end of the shaft portion of the bolt B from the vertical direction. In this state, the clamp C3 can move relative to the pipes P1 and P3, and is moved and installed at a predetermined fixed position of the pipes P1 and P3.

次いで、クランプＣ３のボルトＢに対してナットＮが相対的に締め付けられる。これによって、ボルトＢの頭部とナットＮとの間隔が狭くなり、一対の挟持板２ａ，２ｂの後側は接近する方向に移動し、一対の挟持板２ａ，２ｂは“てこの原理”によってパイプＰ１とパイプＰ３とを挟持し固定する。すなわち、図７に示すように、一対の挟持板２ａ，２ｂとボルトＢ、ナットＮとの接触部が力点、一対の挟持板２ａ，２ｂとパイプＰ３との接触部が支点、一対の挟持板２ａ，２ｂの切欠き部２３とパイプＰ１との接触部が作用点となって、一対の挟持板２ａ，２ｂの後側が接近する方向に移動することによって、一対の挟持板２ａ，２ｂの前側が互いに離れる方向に移動して、切欠き部２３の周縁開口部２１の両端及び切欠き部２３の内周面がパイプＰ１の表面を摺動してパイプＰ１の表面に圧接しパイプＰ１は一対の挟持板２ａ，２ｂによって固定される。また同時に、パイプＰ３は挟持板２ａ，２ｂによる挟持によって固定される。加えて、挟持板２ａ，２ｂによってパイプＰ１に対して後方向に力が加わり、パイプＰ１とボルトＢの軸部との間でパイプＰ３は挟持され固定されると共に、その反作用としてパイプＰ３と一対の挟持板２ａ，２ｂの切欠き部２３の内周面との間でパイプＰ１は挟持され固定される。 Next, the nut N is tightened relative to the bolt B of the clamp C3. As a result, the distance between the head of the bolt B and the nut N is narrowed, the rear sides of the pair of holding plates 2a and 2b move in the approaching direction, and the pair of holding plates 2a and 2b are based on the "lever principle". The pipe P1 and the pipe P3 are sandwiched and fixed. That is, as shown in FIG. 7, the contact portion between the pair of holding plates 2a and 2b and the bolt B and the nut N is the force point, the contact portion between the pair of holding plates 2a and 2b and the pipe P3 is the fulcrum, and the pair of holding plates. The contact portion between the notch 23 of 2a and 2b and the pipe P1 serves as an action point, and the rear side of the pair of holding plates 2a and 2b moves in the approaching direction, whereby the front of the pair of holding plates 2a and 2b As the sides move away from each other, both ends of the peripheral edge opening 21 of the notch 23 and the inner peripheral surface of the notch 23 slide on the surface of the pipe P1 and press contact with the surface of the pipe P1, and the pipe P1 is paired. It is fixed by the holding plates 2a and 2b of. At the same time, the pipe P3 is fixed by being sandwiched by the sandwiching plates 2a and 2b. In addition, a force is applied to the pipe P1 in the rear direction by the holding plates 2a and 2b, and the pipe P3 is sandwiched and fixed between the pipe P1 and the shaft portion of the bolt B, and as a reaction, the pipe P3 is paired with the pipe P3. The pipe P1 is sandwiched and fixed with the inner peripheral surface of the notch 23 of the sandwiching plates 2a and 2b.

このようなクランプＣ３によるパイプＰ１，Ｐ３の接続固定によれば、切欠き部２３から上方にパイプＰ１の一部が突出した状態でパイプＰ１とパイプＰ３とが直交に接続固定される。これにより、例えば図８に示すように、左右方向に所定距離隔てて立設された２本のパイプＰ３の各々の所定の高さ位置に、切欠き部２３が互いに対向するように取り付けられたクランプＣ３によって、２本のパイプＰ１がパイプＰ３に直交して水平に接続固定されると、クランプＣ３に起因する凸部を生じさせることなく２本のパイプＰ１間に平板ＰＬを設置することが可能となる。 According to the connection and fixing of the pipes P1 and P3 by the clamp C3, the pipe P1 and the pipe P3 are connected and fixed orthogonally with a part of the pipe P1 protruding upward from the notch 23. As a result, as shown in FIG. 8, for example, the notch portions 23 are attached to face each other at predetermined height positions of the two pipes P3 erected at a predetermined distance in the left-right direction. When the two pipes P1 are connected and fixed horizontally by the clamp C3 at right angles to the pipe P3, the flat plate PL can be installed between the two pipes P1 without causing a convex portion due to the clamp C3. It will be possible.

（その他のクランプ例）
図９及び図１０に、その他のクランプ例を示す。これらの図に示すクランプＣ４は一対の長方形状の挟持板３ａ，３ｂと、挟持板３ａ，３ｂを連結する２本ボルトＢ１，Ｂ２と、２個のナットＮとから構成される。 (Other clamp examples)
9 and 10 show other examples of clamps. The clamp C4 shown in these figures is composed of a pair of rectangular holding plates 3a and 3b, two bolts B1 and B2 connecting the holding plates 3a and 3b, and two nuts N.

挟持板３ａ，３ｂは同一形状であるので、代表して挟持板３ａについて説明する。挟持板３ａは長方形状の板部材であって四隅は丸み処理されている。挟持板３ａの上下方向（長手方向）上側の側縁の前後方向（短手方向）中央部には円弧状の切欠き部３３が形成され、また挟持板３ａの下側の前後方向両端部にはボルトＢの軸部が挿通可能な２つの貫通孔３４，３５が形成されている。また、前後方向中央部で切欠き部３３の下方には上下方向に所定距離隔てて２つの貫通孔３６，３７が形成されている。切欠き部３３の半径はパイプＰ１の半径と同一又は若干大きく、切欠き部３３の周縁開口部３１の幅ＤはパイプＰ１の直径よりも短く設定されている。また挟持板３ａの下側の２つの貫通孔３４，３５の前後方向の間隔はパイプＰ４が挿通可能な長さに設定されている。なお、貫通孔３７はクランプＣ４を第１実施形態のクランプＣ１と同じ使用形態で使用可能とするためのものであり、本実施形態においては無くても構わない。 Since the holding plates 3a and 3b have the same shape, the holding plate 3a will be described as a representative. The holding plate 3a is a rectangular plate member, and the four corners are rounded. An arcuate notch 33 is formed at the center of the upper side edge of the holding plate 3a in the vertical direction (longitudinal direction) in the front-rear direction (short direction), and both ends in the front-rear direction on the lower side of the holding plate 3a. Is formed with two through holes 34, 35 through which the shaft portion of the bolt B can be inserted. Further, two through holes 36 and 37 are formed below the notch 33 in the central portion in the front-rear direction at a predetermined distance in the vertical direction. The radius of the notch 33 is the same as or slightly larger than the radius of the pipe P1, and the width D of the peripheral opening 31 of the notch 33 is set shorter than the diameter of the pipe P1. Further, the distance between the two through holes 34 and 35 on the lower side of the holding plate 3a in the front-rear direction is set to a length through which the pipe P4 can be inserted. The through hole 37 is for enabling the clamp C4 to be used in the same usage mode as the clamp C1 of the first embodiment, and may not be provided in the present embodiment.

クランプＣ４は、離隔対向した挟持板３ａ，３ｂに形成された２つ貫通孔３４にボルトＢ１，Ｂ２の軸部が挿通され、ボルトＢ１，Ｂ２の軸部の先端にナットＮが螺合されて組立られる。 In the clamp C4, the shaft portions of the bolts B1 and B2 are inserted into the two through holes 34 formed in the holding plates 3a and 3b facing each other, and the nut N is screwed into the tip of the shaft portion of the bolts B1 and B2. Assembled.

図９に示すように、このような構成のクランプＣ４によってパイプＰ１とパイプＰ４とを接続固定する場合、まず、離隔対向した挟持板３ａ，３ｂの切欠き部３３にパイプＰ１が左右方向から挿通される。次いで、パイプＰ４の上端が、挟持板３ａ，３ｂの間で且つボルトＢ１，Ｂ２との間に下側から上方に向かって挿入される。パイプＰ４の上端部には貫通孔９１が形成されている。挟持板３ａ，３ｂの間に挿入されたパイプＰ４は、貫通孔９１と貫通孔３６とが同軸上に位置するように調整され、不図示のボルトの軸部が貫通孔３６及び貫通孔９１に挿通され、不図示のボルトの先端からナットが螺合されることによって挟持板３ａ，３ｂの間に固定される。なお、貫通孔３６及び貫通孔９１の形成位置は、パイプＰ４の上端がパイプＰ１の下端に当接したときに貫通孔９１と貫通孔３６の中心軸が同軸上になるようにするのが好ましい。パイプＰ４が固定されたクランプＣ３はパイプＰ１に対して相対移動可能であり、パイプＰ１の所定の固定位置に移動設置される。なお、パイプＰ１とパイプＰ４とのクランプＣ１への挿通順序は逆にしても勿論かまわない。 As shown in FIG. 9, when connecting and fixing the pipe P1 and the pipe P4 by the clamp C4 having such a configuration, first, the pipe P1 is inserted into the notch 33 of the holding plates 3a and 3b facing each other from the left and right directions. Will be done. Next, the upper end of the pipe P4 is inserted between the holding plates 3a and 3b and between the bolts B1 and B2 from the lower side to the upper end. A through hole 91 is formed at the upper end of the pipe P4. The pipe P4 inserted between the holding plates 3a and 3b is adjusted so that the through hole 91 and the through hole 36 are positioned coaxially, and the shaft portion of the bolt (not shown) is formed in the through hole 36 and the through hole 91. It is inserted and fixed between the holding plates 3a and 3b by screwing a nut from the tip of a bolt (not shown). It is preferable that the through hole 36 and the through hole 91 are formed so that the central axes of the through hole 91 and the through hole 36 are coaxial when the upper end of the pipe P4 abuts on the lower end of the pipe P1. .. The clamp C3 to which the pipe P4 is fixed can move relative to the pipe P1 and is moved and installed at a predetermined fixed position of the pipe P1. Of course, the insertion order of the pipe P1 and the pipe P4 into the clamp C1 may be reversed.

次いで、図１０に示すように、クランプＣ４のボルトＢ１に対してナットＮが相対的に締め付けられる。一方、ボルトＢ２とナットＮとは挟持板３ａ，３ｂの離間する方向への移動を許容する位置に留まっている。ボルトＢ１の頭部とナットＮとの間隔が狭くなると、一対の挟持板３ａ，３ｂの下側部の前側は接近する方向に移動し、一対の挟持板３ａ，３ｂは“てこの原理”によってパイプＰ１を挟持し固定する。すなわち、一対の挟持板３ａ，３ｂとボルトＢ１、ナットＮとの接触部が力点、一対の挟持板３ａ，３ｂとパイプＰ４との接触部が支点、一対の挟持板３ａ，３ｂの切欠き部３３とパイプＰ１との接触部が作用点となって、一対の挟持板３ａ，３ｂの下側部の前側が接近する方向に移動することによって、一対の挟持板３ａ，３ｂの上側部の後側が互いに離れる方向に移動して、切欠き部３３の周縁開口部３１の両端及び切欠き部３３の内周面がパイプＰ１の表面を摺動してパイプＰ１の表面に圧接しパイプＰ１は一対の挟持板３ａ，３ｂによって固定される。 Next, as shown in FIG. 10, the nut N is tightened relative to the bolt B1 of the clamp C4. On the other hand, the bolt B2 and the nut N remain at positions that allow the holding plates 3a and 3b to move in the direction in which they are separated from each other. When the distance between the head of the bolt B1 and the nut N becomes narrower, the front side of the lower side of the pair of holding plates 3a and 3b moves in the approaching direction, and the pair of holding plates 3a and 3b are based on the "lever principle". The pipe P1 is sandwiched and fixed. That is, the contact portion between the pair of holding plates 3a and 3b and the bolt B1 and the nut N is the force point, the contact portion between the pair of holding plates 3a and 3b and the pipe P4 is the fulcrum, and the notch portion of the pair of holding plates 3a and 3b. The contact portion between the 33 and the pipe P1 serves as an action point, and the front side of the lower portion of the pair of holding plates 3a, 3b moves in the approaching direction, so that the rear portion of the upper portion of the pair of holding plates 3a, 3b is reared. As the sides move away from each other, both ends of the peripheral opening 31 of the notch 33 and the inner peripheral surface of the notch 33 slide on the surface of the pipe P1 and press-contact with the surface of the pipe P1, and the pipe P1 is paired. It is fixed by the holding plates 3a and 3b of.

一方、パイプＰ４については挟持板３ａ，３ｂに不図示のボルトで接続され、ボルトＢ１とナットＮによる締め付けによって挟持板３ａ，３ｂの間である程度は挟持固定されているが、ボルトＢ２とナットＮを締めることによって挟持板３ａ，３ｂの間での挟持固定がより強化される。 On the other hand, the pipe P4 is connected to the holding plates 3a and 3b with bolts (not shown), and is held and fixed between the holding plates 3a and 3b to some extent by tightening the bolts B1 and the nut N. By tightening, the holding and fixing between the holding plates 3a and 3b is further strengthened.

なお、図９及び図１０の実施形態ではボルトＢ１，Ｂ２と２つのナットＮによって一対の挟持板３ａ，３ｂを締め付けていたが、１本のボルトとナットで挟持板３ａ，３ｂを締め付けるようにしても構わない。 In the embodiment of FIGS. 9 and 10, the pair of holding plates 3a and 3b are tightened by the bolts B1 and B2 and the two nuts N, but the holding plates 3a and 3b are tightened by one bolt and nut. It doesn't matter.

（その他）
本発明で使用する挟持板の材質としてはパイプを挟持固定可能である限りにおいて限定はないが、例えばステンレス鋼や鉄鋼など高い強度を有するものが望ましい。また挟持板の成形加工は従来公知の加工方法を用いることができ、例えばレーザ加工や打ち抜き加工、切削加工などを用いることができる。 (Other)
The material of the holding plate used in the present invention is not limited as long as the pipe can be held and fixed, but a material having high strength such as stainless steel or steel is desirable. Further, a conventionally known processing method can be used for the forming process of the holding plate, and for example, laser processing, punching processing, cutting processing and the like can be used.

また本発明のクランプは、ステンレスパイプや鉄パイプ、樹脂パイプなど従来公知のパイプに適用することができる。また本発明のクランプは、挟持板に形成する切欠きの形状を調整することによって種々の外径のパイプの接続固定に対応できる。 Further, the clamp of the present invention can be applied to conventionally known pipes such as stainless steel pipes, iron pipes and resin pipes. Further, the clamp of the present invention can be used for connecting and fixing pipes having various outer diameters by adjusting the shape of the notch formed in the holding plate.

以上説明した実施形態ではパイプの断面形状は円形であったがこれに限定されるものではなく、楕円や多角形であっても構わない。ただし、挟持板に形成される切欠き部はパイプの断面形状に合わせた形状とするのが望ましい。 In the embodiment described above, the cross-sectional shape of the pipe is circular, but the present invention is not limited to this, and an ellipse or a polygon may be used. However, it is desirable that the notch formed in the holding plate has a shape that matches the cross-sectional shape of the pipe.

本発明のクランプは、パイプの接続部分においてパイプの一部を覆うことなく２本のパイプを直交状態に接続固定でき、これにより、クランプで覆われていないパイプの部分に接触するように板状体を取り付けることで、クランプに起因する凸部が板状体に生じることがなく、また従来のようにクランプとの当接を避けるための切欠きを板状体に形成する必要がなくなる。しかも従来のクランプに比べて部品点数が少なく軽量にすることが可能となる。 The clamp of the present invention can connect and fix two pipes in an orthogonal state without covering a part of the pipe at the connecting portion of the pipe, whereby it has a plate shape so as to come into contact with the portion of the pipe not covered by the clamp. By attaching the body, the convex portion due to the clamp does not occur in the plate-shaped body, and it is not necessary to form a notch in the plate-shaped body for avoiding contact with the clamp as in the conventional case. Moreover, the number of parts is smaller than that of the conventional clamp, and the weight can be reduced.
