Description

本発明は、２部材構成の管材クランプで異径管の確実な締結ができるようにした管材クランプの異径管対応構造に関する。   The present invention relates to a structure for handling different diameter pipes of a tube clamp that enables reliable fastening of different diameter pipes with a two-part tube clamp.

従来、建築又は建設用の足場を組むような場合に用いられる管材用のクランプとして、円弧状に形成された一対の挟持片の各一端をヒンジ部を介して連結し、他端に突片を対設し、両突片に形成された通し孔に貫通したボルトで締結するものが知られている。これは、上記ヒンジ部によって２つの挟持片を開閉する構造になっており、管材の径が多少異なっても、両挟持片に設けられた突片をボルト、ナットで強く締め付けることによってクランプすることはできる。   Conventionally, as a clamp for a pipe material used when building a scaffold for construction or construction, one end of a pair of holding pieces formed in an arc shape is connected via a hinge portion, and a projecting piece is connected to the other end. It is known that a bolt is provided that is opposed to each other and penetrates through holes formed in both projecting pieces. This is a structure in which the two clamping pieces are opened and closed by the hinge part, and even if the diameters of the pipe materials are slightly different, clamping is performed by strongly tightening the projecting pieces provided on both clamping pieces with bolts and nuts. I can.

ところが、小さな径の管材をクランプする場合と、大きな径の管材をクランプする場合は、対設された突片は非平行になっている。つまり、小さな径の管材をクランプする場合は、両突片が成す角度は先端が閉じ気味になり、大きな径の管材をクランプする場合は、両突片の成す角度は先端が開き気味になる。その状態でボルトで締めると、ボルトの裏面はぴったりと突片の表面に面接触せず、ボルトの裏面の周縁の一部が突片の表面に点又は線接触するだけとなる。このため、ボルトを締めたときにその軸部に加えられる力は偏在するので、強く締め付けすぎると、折損してしまう可能性がある。   However, when clamping a pipe material with a small diameter and when clamping a pipe material with a large diameter, the opposing projecting pieces are non-parallel. That is, when clamping a pipe material with a small diameter, the angle formed by the two protruding pieces is close to the tip, and when clamping a pipe material with a large diameter, the angle formed by the two protruding pieces is slightly open at the tip. When the bolt is tightened in this state, the back surface of the bolt does not exactly come into surface contact with the surface of the projecting piece, and only a part of the periphery of the back surface of the bolt makes point or line contact with the surface of the projecting piece. For this reason, since the force applied to the shaft portion is unevenly distributed when the bolt is tightened, if the bolt is tightened too much, it may break.

このため、異径管締結用脚部の先端に閉鎖エレメントの基部を枢着し、この閉鎖エレメントの先端側には横方向に長い楔孔を設けて、この部分を他方の脚部の先端に形成した切欠に係合させ、脚部の側面へ接するよう上記楔孔へ楔を挿し込むことで、斜面の作用により一対の脚部を圧接させて広範囲にわたる異径管の挟持も可能となるようにしている。
特開平６−２０７４６１号公報 Therefore, the base of the closure element is pivotally attached to the tip of the leg for fastening the different diameter pipe, and a long wedge hole is provided in the lateral direction on the tip of the closure element, and this part is provided at the tip of the other leg. By engaging the formed notch and inserting the wedge into the wedge hole so as to contact the side surface of the leg, the pair of legs are pressed by the action of the inclined surface so that a wide range of different diameter pipes can be held. I have to.
JP-A-6-207461

しかしながら、上記管材クランプは基材に一対の脚片を枢着して、これら一対の脚片を楔穴に楔を挿す閉鎖エレメントで締め付ける３部材構成を採用するため、２部材構成の管用クランプに比べて高価であって、使い勝手も良くないためる市場提供されるに至っていない。   However, the pipe clamp employs a three-member configuration in which a pair of leg pieces are pivotally attached to a base material, and the pair of leg pieces are fastened with a closing element that inserts a wedge into a wedge hole. Compared to the above, it has not been provided in a market that is expensive and not easy to use.

本発明は前記問題点を解消し、異径管であっても容易かつ安定、確実に締結できる管材クランプの異径管対応構造を提供することをその課題とする。   An object of the present invention is to solve the above-mentioned problems and to provide a pipe clamp-compatible structure for a pipe clamp that can be easily, stably and reliably fastened even with a different diameter pipe.

前記課題を解決するため、請求項１に係る発明は、円弧状に形成された一対の挟持片の各一端をヒンジ部を介して連結し、他端に突片を対設し、両突片に形成された通し孔に貫通したボルトで締結する管材用のクランプにおいて、上記ボルトの頭部側の突片には、上記通し孔をはさんで上記突片の幅方向の両側表面に、上記突片の突出方向に沿って上記ボルトの頭部裏面を受ける受け部を円弧状に盛り上げ形成したことを特徴とする。   In order to solve the above-mentioned problem, the invention according to claim 1 is characterized in that one end of a pair of sandwiching pieces formed in an arc shape is connected via a hinge portion, and a protruding piece is provided at the other end. In the clamp for a pipe member fastened with a bolt penetrating the through hole formed in the projecting piece on the head side of the bolt, the both side surfaces in the width direction of the projecting piece sandwiching the through hole, The receiving portion for receiving the back surface of the head of the bolt is formed so as to rise in an arc shape along the protruding direction of the protruding piece.

請求項２に係る発明は、上記ボルトには、抜け止め片が取り付けられていることを特徴とする。   The invention according to claim 2 is characterized in that a retaining piece is attached to the bolt.

請求項１に係る発明によれば、管材をクランプする場合、一方の突片の通し穴を貫通したボルトの頭部裏面は通し穴の両側の受け部に接触するが、受け部は円弧状に盛り上げ形成されているから、ボルトの軸部の角度に応じて接触位置は変わっていく。そして、いずれの場合も、通し穴の両側に等距離に設けられた受け部において接触位置を結ぶ線はボルトの中心を通ることになる。したがって、ボルトを締め付けたとき、ボルトの軸部に加えられる力は偏らない。このため、簡単な構造でありながら、ある程度の範囲内ある異径管を容易かつ安定、確実に締結することができる。   According to the first aspect of the present invention, when clamping the pipe material, the back surface of the head of the bolt penetrating the through hole of one of the projecting pieces comes into contact with the receiving portions on both sides of the through hole, but the receiving portion has an arc shape. Since it is formed so as to rise, the contact position changes according to the angle of the bolt shaft. In either case, the line connecting the contact positions in the receiving portions provided at equal distances on both sides of the through hole passes through the center of the bolt. Therefore, when the bolt is tightened, the force applied to the bolt shaft is not biased. For this reason, it is possible to easily, stably and surely fasten different diameter pipes within a certain range while having a simple structure.

請求項２に係る発明によれば、ボルトには抜け止め片が取り付けられているので、一方の通し穴から挿通されたボルトは脱落することがない。したがって、クランプの保管、輸送や管材の締結作業等の能率が向上する。   According to the second aspect of the present invention, since the retaining piece is attached to the bolt, the bolt inserted from one through hole does not fall off. Therefore, the efficiency of storage, transportation, and fastening work of pipe materials is improved.

以下に本発明に係る管材クランプの異径管対応構造の実施形態を図面について説明する。   Embodiments of the pipe clamp structure for different diameter pipes according to the present invention will be described below with reference to the drawings.

図１〜図３において符号１は、管材２と管材３とを図１に示す通り締結する管材クランプを示す。このクランプ１は、２個のクランプ１によって２個の管材を組むためのもので、各クランプ１は、挟持片４と挟持片５の一端をヒンジ部６で連結し、他端に突片８と突片９を対設した構成となっている。   1-3, the code | symbol 1 shows the pipe material clamp which fastens the pipe material 2 and the pipe material 3 as shown in FIG. This clamp 1 is for assembling two pipe members by two clamps 1. Each clamp 1 connects one end of the holding piece 4 and the holding piece 5 with a hinge portion 6 and the other end is a protruding piece 8. And the projecting piece 9 is provided in a configuration.

両クランプ１の挟持片４は互いに結合軸１２を介して連結されているので、ここでは挟持片４を固定挟持片とし、挟持片５を可動挟持片として説明する。   Since the sandwiching pieces 4 of both clamps 1 are connected to each other via the coupling shaft 12, the sandwiching piece 4 will be described as a fixed sandwiching piece and the sandwiching piece 5 will be described as a movable sandwiching piece.

各クランプ１において、一方の突片９にはボルト７の通し孔１０が設けられ、他方の突片８にはボルト７を螺合させる雌ねじ１１が設けられている。クランプ1とクランプ１とを直交させるか、平行にするかあるいは斜めにするかによって管材の組み方を適宜選択すればよい。   In each clamp 1, one projecting piece 9 is provided with a through hole 10 for a bolt 7, and the other projecting piece 8 is provided with a female screw 11 for screwing the bolt 7. The method of assembling the pipes may be appropriately selected depending on whether the clamp 1 and the clamp 1 are orthogonal, parallel, or oblique.

ボルト７の頭部７ａ側の可動挟持片５における突片９には、上記通し孔１０をはさんで上記突片９の幅方向の両側表面に、上記突片９の突出方向に沿って上記ボルト７の頭部裏面を受ける受け部１３が円弧状に盛り上げ形成されている。これらの受け部１３は、中央部分が最も高くなり、挟持片５をプレス成形する際にこの受け部１３も同時成形される。   The projecting piece 9 of the movable sandwiching piece 5 on the head 7a side of the bolt 7 is formed on the both side surfaces in the width direction of the projecting piece 9 across the through hole 10 and along the projecting direction of the projecting piece 9. A receiving portion 13 for receiving the back surface of the head of the bolt 7 is formed so as to be raised in an arc shape. These receiving portions 13 have the highest central portion, and when the holding piece 5 is press-molded, the receiving portions 13 are simultaneously formed.

上記の通り受け部１３を配設すると、図５（ａ）（ｂ）（ｃ）のように、固定挟持片４と可動挟持片５とにより管材２をボルト７で締結して挟持させると、一方の突片８の雌ねじに対してボルト７をねじ込んだとき、管材２の直径が、図５（ａ）に示すように標準直径よりも小さい場合は、両突片８、９が成す角度は先端が閉じ気味になるから、ボルト７は突片９に対して傾き、ボルト７の頭部７ａの裏面は受け部１３の基部側に接触することになる。同図（ｂ）に示すように標準直径の場合には、両突片８、９が成す角度は平行となるから、ボルト７の頭部７ａの裏面は受け部１３の中央の頂部に接触することになる。また、同図（ｃ）に示すように標準直径よりも大きい場合には、両突片８、９が成す角度は先端が開き気味になり、傾いたボルト７の頭部７ａの裏面は受け部１３の先端側に接触することになる。   When the receiving portion 13 is disposed as described above, as shown in FIGS. 5A, 5 </ b> B, and 5 </ b> C, when the tubular material 2 is fastened and clamped by the bolt 7 with the fixed clamping piece 4 and the movable clamping piece 5, When the bolt 7 is screwed into the female thread of one of the projecting pieces 8 and the diameter of the tube material 2 is smaller than the standard diameter as shown in FIG. 5 (a), the angle formed by both projecting pieces 8 and 9 is Since the tip is closed, the bolt 7 is inclined with respect to the protruding piece 9, and the back surface of the head 7 a of the bolt 7 comes into contact with the base side of the receiving portion 13. In the case of a standard diameter as shown in FIG. 5B, the angle formed by the two projecting pieces 8 and 9 is parallel, so that the back surface of the head 7a of the bolt 7 is in contact with the central top of the receiving portion 13. It will be. In addition, when the diameter is larger than the standard diameter as shown in FIG. 5C, the angle formed by the two projecting pieces 8 and 9 becomes open and the back surface of the head 7a of the tilted bolt 7 is the receiving portion. 13 is in contact with the tip side.

いずれの場合も、通し穴１０の両側に等距離に設けられた受け部１３において接触位置を結ぶ線はボルト７の軸部の中心を通ることになる。したがって、ボルト７を締め付けたとき、ボルト７の軸部に加えられる力は偏らない。このため、簡単な構造でありながら、ある程度の範囲内ある異径管を容易かつ安定、確実に締結することができる。   In any case, the line connecting the contact positions in the receiving portions 13 provided at equal distances on both sides of the through hole 10 passes through the center of the shaft portion of the bolt 7. Therefore, when the bolt 7 is tightened, the force applied to the shaft portion of the bolt 7 is not biased. For this reason, it is possible to easily, stably and surely fasten different diameter pipes within a certain range while having a simple structure.

また、図１〜図５において符号１４は抜け止め片である。この抜け止め変１４は合成樹脂などの薄片で、図４に示す通り、内側にねじ溝へ係合させる突部１４ａを間隔を置いて複数設けることで、抜け止め片１４をボルト７へ押し付けると上記突部１４ａが変形してねじ溝へ嵌まり込んで復元し、ボルト７の軸部のねじと噛み合うので、ボルト７がその通し孔１０から抜けなくなるものであり、この抜け止め片１４を取り付けられたボルト７は、クランプ１がどのような姿勢に置かれる場合もボルト７を固定部９に止め着けられ脱落を生じない。   1 to 5, reference numeral 14 denotes a retaining piece. This retaining deformation 14 is a thin piece of synthetic resin or the like, and as shown in FIG. 4, when a plurality of protrusions 14 a that are engaged with the screw grooves are provided at intervals, the retaining piece 14 is pressed against the bolt 7. The protrusion 14a is deformed and fitted into the screw groove to be restored, and meshes with the screw of the shaft portion of the bolt 7, so that the bolt 7 cannot be removed from the through hole 10, and the retaining piece 14 is attached. When the clamp 1 is placed in any posture, the bolt 7 is fixed to the fixing portion 9 and does not fall off.

次に、図６〜図８は他の実施形態で、同図において符号１は、垂木１５と管材２の結合を行なう管材クランプを示す。このクランプ１は、固定挟持片４と可動挟持片５の一端をヒンジ部６（図示せず）で連結し、他端にボルト７で連結するための突片８と９を対設して、一方の突片９にはボルト７の通し孔１０をあけ、他方の突片８にはボルト７を螺合させる雌ねじ１１を設ける構造としたものであって、このクランプ１における固定挟持片５をＬ形をなす垂木１５への取付金具１６における水平片１６ａへ結合軸１２で結合することで構成する。そして、取付金具１６とクランプ１の固定挟持片４との結合状態は、図６に示す通り垂木１４と管材２が直交するか、図面には示してないが垂木１５と管材２とが平行するか、必要に応じては垂木１５と管材２が直交又は平行に結合変換されるようにする。   Next, FIGS. 6 to 8 show other embodiments. In the figure, reference numeral 1 denotes a pipe clamp for coupling the rafter 15 and the pipe 2. The clamp 1 has one end of a fixed sandwich piece 4 and one end of a movable sandwich piece 5 connected by a hinge portion 6 (not shown), and a projecting piece 8 and 9 for connection by a bolt 7 to the other end. One projecting piece 9 is provided with a through-hole 10 for a bolt 7, and the other projecting piece 8 is provided with a female screw 11 for screwing the bolt 7. It is configured by connecting to the horizontal piece 16a of the mounting bracket 16 to the L-shaped rafter 15 with the connecting shaft 12. And as for the connection state of the attachment metal fitting 16 and the fixed clamping piece 4 of the clamp 1, as shown in FIG. 6, the rafter 14 and the tube material 2 are orthogonal, or although not shown in the drawing, the rafter 15 and the tube material 2 are parallel to each other. Alternatively, the rafters 15 and the pipe material 2 are coupled and converted orthogonally or in parallel as necessary.

この実施例２のクランプ１における可動挟持片４に設けた突片８も、その表面側に円弧状をなす一対の受け部１３をボルト７の通し孔１０を挟むようにその両側に設けられ、この受け部１３によって図５（ａ）（ｂ）（ｃ）に示したものと同様にボルト７を受けることにより、管材の直径がある程度の範囲内にあれば、異径管を容易かつ安定、確実に締結することができる。   The projecting piece 8 provided on the movable holding piece 4 in the clamp 1 of the second embodiment is also provided with a pair of receiving portions 13 having an arc shape on the surface side so as to sandwich the through hole 10 of the bolt 7, By receiving the bolt 7 in the same manner as shown in FIGS. 5 (a), 5 (b) and 5 (c) by this receiving portion 13, if the diameter of the pipe material is within a certain range, the different diameter pipe can be easily and stably. It can be securely fastened.

この実施例においても、可動挟持片５における突片９に設けた通し孔１０にボルト７を通すとき、ボルト７の軸部に抜け止め片１４を圧嵌することで、ボルト７が通し孔から抜け落ちることがないようにすることができる。   Also in this embodiment, when the bolt 7 is passed through the through hole 10 provided in the projecting piece 9 of the movable holding piece 5, the bolt 7 is removed from the through hole by press fitting the retaining piece 14 into the shaft portion of the bolt 7. It can be prevented from falling out.
