Description

本発明は、板状部材に横から嵌合して固定出来るコ形クランプと鋼管に対して把持固定出来るパイプクランプとを互いに連結して成るパイプクランプ装置に関するものである。 The present invention relates to a pipe clamp device in which a U-shaped clamp that can be fitted and fixed to a plate-like member from the side and a pipe clamp that can be held and fixed to a steel pipe are connected to each other.

この種のパイプクランプ装置は、建設現場での足場の組立てなどに活用されているもので、コ形クランプに対してパイプクランプが一定向きに固定された向き固定型と、特許文献１に記載のように、コ形クランプに対するパイプクランプの取付け向きを９０度の範囲で切り換えられる向き可変型のものが知られている。この向き固定型、向き自在型の何れにおいても、コ形クランプに対してパイプクランプが、両者を連結する連結用軸体の周りで自由に回転できるパイプクランプ遊転型と、パイプクランプを連結用軸体の周りに回転させることが出来ないパイプクランプ完全固定型と、特許文献１に記載されるように、連結用軸体の周りにパイプクランプを９０度間隔で角度変更できるようにしたパイプクランプ角度可変型が使い分けられている。 This type of pipe clamp device is used for assembling a scaffolding at a construction site, and the orientation fixing type in which the pipe clamp is fixed in a fixed direction with respect to the U-shaped clamp, and the method described in Patent Document 1.

In both the fixed orientation type and the free orientation type, the pipe clamp can be rotated freely around the connecting shaft that connects the two to the U-shaped clamp, and the pipe clamp can be connected. Pipe clamp completely fixed type that cannot be rotated around the shaft body, and a pipe clamp that can change the angle of the pipe clamp around the connecting shaft body at intervals of 90 degrees as described in Patent Document 1. Variable angle type is used properly.

即ち、作業現場では、梁や柱用の形鋼に鋼管を取り付けて、足場や安全手摺りなどの枠組み構造体を組み立てる場合には、パイプクランプ完全固定型又はパイプクランプ角度可変型を使用し、枠組み構造体の補強のために斜めに鋼管を取り付ける場合には、パイプクランプ遊転型を使用することになるので、少なくとも二種類のパイプクランプ装置を準備しておかなければならず、結果的に数多くのパイプクランプ装置が必要になり、選択の手間もかかる。 That is, at the work site, when assembling a framework structure such as a scaffold or safety handrail by attaching a steel pipe to the beam or column shape steel, use the pipe clamp fully fixed type or the pipe clamp angle variable type, When steel pipes are installed at an angle to reinforce the frame structure, a pipe clamp free-rolling type is used, so at least two types of pipe clamp devices must be prepared, and as a result A large number of pipe clamping devices are required, and the selection is troublesome.

本発明は、上記のような従来の問題点を解消することのできるパイプクランプ装置を提案するものであって、請求項１に記載の本発明に係るパイプクランプ装置は、後述する実施例との関係を理解し易くするために、当該実施例の説明において使用した参照符号を括弧付きで付して示すと、コ形クランプ(1)とパイプクランプ(2)とを互いに連結して成るパイプクランプ装置であって、パイプクランプ(2)のベース部材(10)とコ形クランプ(1)のコ形本体(6)とは、連結用軸体(16,27)の軸心の周りの相対回転と当該連結用軸体(16,27)の軸心方向の一定範囲内の接近離間移動とが可能に、当該連結用軸体(16,27)を介して連結され、前記ベース部材(10)と前記コ形本体(6)には、この両者が前記連結用軸体(16,27)の軸心方向の接近限位置にあるときに互いに嵌合してこの両者の相対回転を不能にする嵌合部(22a,22b,24a,24b)が設けられ、前記ベース部材(10)と前記コ形本体(6)との間には、この両者を前記嵌合部(22a,22b,24a,24b)が互いに嵌合する接近限位置に付勢保持する圧縮バネ(25)が介装され、この圧縮バネ(25)の付勢力に抗して前記ベース部材(10)と前記コ形本体(6)を互いに離間移動させたとき、前記嵌合部(22a,22b,24a,24b)が互いに離脱してこの両者の相対回転が可能になる構成となっている。 The present invention proposes a pipe clamp device capable of solving the above-mentioned conventional problems, and the pipe clamp device according to the present invention according to claim 1 is provided with the embodiments described later. In order to facilitate understanding of the relationship, the reference numerals used in the description of the embodiment are shown in parentheses, and a pipe clamp formed by connecting a U-shaped clamp (1) and a pipe clamp (2) to each other. The base member (10) of the pipe clamp (2) and the U-shaped body (6) of the U-shaped clamp (1) are relative rotations about the axis of the connecting shaft body (16, 27). And the connecting shaft body (16, 27) are connected via the connecting shaft body (16, 27) so as to be able to approach and move within a certain range in the axial direction of the connecting shaft body (16, 27), and the base member (10) And the U-shaped body (6) are fitted to each other when they are at the approach limit position in the axial direction of the connecting shaft (16, 27). A fitting portion (22a, 22b, 24a, 24b) that disables relative rotation of both is provided, and between the base member (10) and the U-shaped body (6), the both are fitted. A compression spring (25) that biases and holds the portion (22a, 22b, 24a, 24b) in an approaching limit position where the parts (22a, 22b, 24a, 24b) are fitted to each other is interposed, and the base member ( When the 10) and the U-shaped main body (6) are moved away from each other, the fitting portions (22a, 22b, 24a, 24b) are separated from each other and can be rotated relative to each other. .

上記の本発明の構成によれば、パイプクランプの前記ベース部材とコ形クランプの前記コ形本体とは、この両者の前記嵌合部が圧縮バネの付勢力によって互いに嵌合している状態では、この両者を連結する連結用軸体の周りに相対回転することが出来ないので、従来のパイプクランプ固定型として使用することが出来る。このとき、パイプクランプとコ形クランプとの間に前記連結用軸体の周りに多少の回転力が作用しても、前記嵌合部は、パイプクランプとコ形クランプとが前記連結用軸体の軸心方向に相対的に一定距離だけ互いに離間移動しない限り外れることはないので、従来のパイプクランプ固定型と変わりなく安全に使用することが出来る。 According to the configuration of the present invention described above, the base member of the pipe clamp and the U-shaped main body of the U-shaped clamp are in a state where the fitting portions of both are fitted to each other by the urging force of the compression spring. Since it cannot rotate relative to the connecting shaft that connects the two, it can be used as a conventional pipe clamp fixing type. At this time, even if a slight rotational force acts around the connecting shaft between the pipe clamp and the U-shaped clamp, the fitting portion has the pipe clamp and the U-shaped clamp connected to the connecting shaft. As long as they do not move apart from each other by a relatively fixed distance in the axial direction, they can be used safely without changing from the conventional pipe clamp fixed type.

そして、パイプクランプ遊転型として使用するときは、例えばコ形クランプを先に形鋼などの板状部材に固定した状態でパイプクランプを鋼管に把持固定し、係る状態で当該鋼管を利用してパイプクランプをコ形クランプから離す方向、即ち、両者を連結している連結用軸体の軸方向に沿ってコ形クランプから離すように力を掛けることにより、前記嵌合部を圧縮バネの付勢力に抗して互いに離間移動させ、コ形クランプに対してパイプクランプを前記連結用軸体の周りに回転可能な状態に切り換えることが出来る。この状態で前記鋼管をパイプクランプと一体に前記連結用軸体の周りに自由に回転させ、当該鋼管を任意の角度に設定して取り付けることが出来る。即ち、従来のパイプクランプ遊転型と全く同様に使用することが出来る。 And when using it as a pipe clamp free-rolling type, for example, the pipe clamp is held and fixed to a steel pipe in a state where the U-shaped clamp is first fixed to a plate-like member such as a shape steel, and the steel pipe is used in such a state. By applying a force so as to separate the pipe clamp from the U-shaped clamp, that is, along the axial direction of the connecting shaft that connects the two, the fitting portion is attached with a compression spring. The pipe clamp can be switched to a state in which the pipe clamp can be rotated around the connecting shaft relative to the U-shaped clamp. In this state, the steel pipe can be freely rotated around the connecting shaft integrally with the pipe clamp, and the steel pipe can be set at an arbitrary angle and attached. That is, it can be used in exactly the same manner as a conventional pipe clamp free-running type.

上記のように本発明のパイプクランプ装置は、パイプクランプ固定型とパイプクランプ遊転型の何れのタイプとしても切り換えて使用することが出来、従来のように、現場に二種類のパイプクランプ装置を準備しておく必要がなくなり、結果的に数少ないパイプクランプ装置で対応できると共に、選択の手間も不要になる。しかも、固定型・遊転型の切り換えに際して特別な部品の着脱作業なども不要であり、極めて簡単な操作で切り換えることが出来る。 As described above, the pipe clamp device of the present invention can be used by switching between the pipe clamp fixed type and the pipe clamp free-running type. It is not necessary to prepare, and as a result, it is possible to cope with a few pipe clamping devices, and it is not necessary to select. Moreover, there is no need to attach or detach special parts when switching between the fixed type and the idle type, and the switching can be performed with an extremely simple operation.

尚、前記連結用軸体(16)が、前記コ形本体(6)の１つの角部に、当該角部の一方の側壁部(3)から直角に突出する第一の向きと、当該角部の他方の側壁部(5)から直角に突出する第二の向きとの間で揺動のみ可能に取り付けられた向き可変型のパイプクランプ装置に本発明を実施する場合、請求項２に記載のように、前記連結用軸体(16)に前記ベース部材(10)を支持する支持座板(21)を相対回転不能に設け、前記ベース部材(10)は、前記連結用軸体(16)に、その軸心の周りに相対回転自在に嵌合させると共に前記支持座板(21)に支持させ、前記圧縮バネ(25)は、前記連結用軸体(16)の先端螺軸部(18)に螺嵌したナット(26)と前記ベース部材(10)との間に介装し、前記嵌合部(22a,22b,24a,24b)は、前記支持座板(21)と前記ベース部材(10)とに設けることが出来る。この構成によれば、本発明を従来の向き可変型パイプクランプ装置にも簡単に実施することが出来る。しかも、この向き可変型では、コ形クランプのコ形本体の角部にパイプクランプのベース部材が取り付けられるので、前記コ形本体とベース部材との間の互いに隣接する面が非常に小さくなるが、コ形クランプ側の前記嵌合部を前記連結用軸体に設けられた支持座板に設けるのであるから、当該嵌合部を無理なく容易に構成することが出来る。 The connecting shaft (16) has a first direction projecting perpendicularly from one side wall (3) of the corner at one corner of the U-shaped body (6), and the corner. When the present invention is applied to a variable-direction pipe clamp device that is mounted so as to be able to swing only between a second direction protruding at right angles from the other side wall portion (5) of the portion, the present invention is described in claim 2. As described above, the connecting shaft (16) is provided with a support seat plate (21) for supporting the base member (10) so as not to be relatively rotatable, and the base member (10) is connected to the connecting shaft (16 ), And the support seat plate (21), and the compression spring (25) is fitted to the tip screw shaft portion (16) of the connecting shaft body (16). 18) is interposed between the nut (26) screwed into the base member (10), and the fitting portions (22a, 22b, 24a, 24b) are provided between the support seat plate (21) and the base. It can be provided on the member (10). According to this configuration, the present invention can be easily implemented in a conventional direction variable pipe clamp device. In addition, in this variable orientation type, since the base member of the pipe clamp is attached to the corner of the U-shaped main body of the U-shaped clamp, the adjacent surfaces between the U-shaped main body and the base member become very small. Since the fitting part on the U-shaped clamp side is provided on the support seat plate provided on the connecting shaft body, the fitting part can be easily configured without difficulty.

前記支持座板(21)は、前記連結用軸体(16)に溶接により取り付けることもできるが、前記連結用軸体(16)の角軸部(17)に相対回転不能に嵌合支持させるときは、前記支持座板(21)の取付けが簡単になり、安価に実施することが出来る。 The support seat plate (21) can be attached to the connecting shaft body (16) by welding, but is fitted and supported on the angular shaft portion (17) of the connecting shaft body (16) so as not to be relatively rotatable. Sometimes, the mounting of the support seat plate (21) is simplified and can be carried out at a low cost.

向き固定型のパイプクランプ装置に本発明を実施する場合は、請求項３に記載のように、前記連結用軸体は、前記コ形本体(6)の１つの側壁部(3)と前記ベース部材(10)とを相対回転自在に連結するボルトナット(27,26)で構成し、そのボルト(27)は、その頭部が隣接する前記側壁部(3)又は前記ベース部材(10)に対しては相対回転不能に貫通させ、前記圧縮バネ(25)は、前記ボルト(27)の頭部又はナット(26)とその内側に隣接する前記側壁部(3)又は前記ベース部材(10)との間に介装することが出来る。この場合、請求項４に記載のように、前記ボルト(27)には、前記側壁部(3)と前記ベース部材(10)との間に挟まれる支持座板(21)を相対回転不能に設け、前記嵌合部(22a,22b,24a,24b)は、前記ボルト(27)に対して相対回転自在な前記ベース部材(10)又は側壁部(3)と前記支持座板(21)との間に設けることが出来る。更に、請求項５に記載のように、前記ボルト(27)には、前記側壁部(3)又は前記ベース部材(10)に設けられた角孔(28)を相対回転不能に貫通する角軸部(29)を設け、前記支持座板(21)は、前記ボルト(27)の角軸部(29)に相対回転不能に嵌合支持させることが出来る。 When the present invention is applied to a direction-fixed type pipe clamp device, as described in claim 3, the connecting shaft body includes one side wall portion (3) of the U-shaped main body (6) and the base. The bolts and nuts (27, 26) are connected to the member (10) so as to be relatively rotatable.The bolts (27) are connected to the side wall (3) or the base member (10) adjacent to the head. On the other hand, the compression spring (25) is passed through in a relatively non-rotatable manner, and the compression spring (25) includes the head or nut (26) of the bolt (27) and the side wall (3) or the base member (10) adjacent to the inside thereof. Can be intervened between. In this case, as described in claim 4, the bolt (27) is provided with a support seat plate (21) sandwiched between the side wall (3) and the base member (10) so as not to be relatively rotatable. The fitting portion (22a, 22b, 24a, 24b) includes the base member (10) or the side wall portion (3) and the support seat plate (21) that are rotatable relative to the bolt (27). Can be provided. Furthermore, as described in claim 5, the bolt (27) has a square shaft that passes through a square hole (28) provided in the side wall (3) or the base member (10) in a relatively non-rotatable manner. A portion (29) is provided, and the support seat plate (21) can be fitted and supported on the angular shaft portion (29) of the bolt (27) so as not to be relatively rotatable.

更に、請求項６に記載のように、前記嵌合部は、バーリング加工により形成された筒状突起(24a,24b)と、当該筒状突起(24a,24b)が嵌合する貫通孔(22a,22b)とで構成することが出来る。この種のパイプクランプ装置のパイプクランプのベース部材は、コ形クランプのコ形本体又は支持座板を構成する板材よりも薄い板材のプレス加工により構成されるので、このパイプクランプのベース部材側にバーリング加工により筒状突起を形成させ、相手側のコ形本体又は支持座板に前記貫通孔を形成することになる。この構成によれば、突起をプレス加工により形成することが出来るので、他のピン状部材を取り付けて構成する場合よりも安価に実施することが出来る。しかも、突起の先端が円弧面になる場合と比較して、コ形クランプとパイプクランプとの間に、その両者間の連結用軸体の周りの回転力が作用しても、嵌合部を構成する突起が相手側の貫通孔内から容易に抜け出してしまう恐れが少なく、パイプクランプ固定型として安定的に使用することが出来る。 Furthermore, as described in claim 6, the fitting portion includes a cylindrical projection (24a, 24b) formed by burring and a through hole (22a) into which the cylindrical projection (24a, 24b) is fitted. 22b). The base member of the pipe clamp of this type of pipe clamp device is formed by pressing a plate material that is thinner than the plate material constituting the U-shaped main body or the support seat plate of the U-shaped clamp. A cylindrical protrusion is formed by burring, and the through hole is formed in the opposite U-shaped main body or support seat plate. According to this configuration, since the protrusion can be formed by press working, it can be implemented at a lower cost than the case where the other pin-shaped member is attached. In addition, compared with the case where the tip of the protrusion is an arcuate surface, even if the rotational force around the connecting shaft between the U-shaped clamp and the pipe clamp acts, the fitting portion is There is little possibility that the constituent protrusions will easily come out of the counterpart through-hole, and it can be used stably as a pipe clamp fixing mold.

以下に本発明の好適実施形態を添付図に基づいて説明すると、１は、鉄骨などのフランジ部を挟持するコ形クランプであり、２は鋼管などを抱持固定するパイプクランプである。コ形クランプ１は、一対の並列する側壁部３，４とこの両側壁部３，４を連結する側壁部５とから成るコ形本体６と、側壁部４を螺合貫通する締結用螺軸７とから成り、コ形本体６には、一方の側壁部３の先端近傍位置から他方の側壁部４の先端近傍位置までコの字形に連続して外側に張り出す突曲部８が形成され、更に、側壁部３，５間の角部には、前記突曲部８の巾よりも小巾で且つ両側壁部３，５間にわたって連続するＬ形貫通孔９が設けられている。尚、締結用螺軸７の内端には、皿バネ７ａが当該螺軸７の軸心の周りに回転可能に装着されている。 A preferred embodiment of the present invention will be described below with reference to the accompanying drawings. Reference numeral 1 denotes a U-shaped clamp that holds a flange portion such as a steel frame, and 2 denotes a pipe clamp that holds and fixes a steel pipe or the like. The U-shaped clamp 1 includes a U-shaped main body 6 including a pair of side wall portions 3 and 4 and side wall portions 5 that connect both side wall portions 3 and 4, and a fastening screw shaft that is threaded through the side wall portion 4. The U-shaped main body 6 is formed with a protruding portion 8 that continuously protrudes outward in a U-shape from a position near the tip of one side wall 3 to a position near the tip of the other side wall 4. Furthermore, an L-shaped through hole 9 is provided at the corner between the side wall portions 3 and 5, which is smaller than the width of the bent portion 8 and continuous between the side wall portions 3 and 5. A disc spring 7 a is mounted on the inner end of the fastening screw shaft 7 so as to be rotatable around the axis of the screw shaft 7.

パイプクランプ２は、ベース部材１０、このベース部材１０の一端に支軸１１で開閉自在に軸支された押さえ部材１２、ベース部材１０の他端に支軸１３で揺動自在に軸支された締結用螺軸１４、及び当該締結用螺軸１４に螺嵌された締結用ナット１５から構成され、ベース部材１０と押さえ部材１２との間に鋼管などを挟んだ状態で締結用螺軸１４を押さえ部材１２の先端二股部１２ａに嵌合させ、ナット１５で押さえ部材１２をベース部材１０側へ押圧することにより、前記鋼管などをベース部材１０と押さえ部材１２との間に抱持固定するものである。 The pipe clamp 2 is pivotally supported by a base member 10, a pressing member 12 pivotally supported by one end of the base member 10 with a support shaft 11, and a pivot shaft 13 by another end of the base member 10. The fastening screw shaft 14 is composed of a fastening screw shaft 14 and a fastening nut 15 screwed into the fastening screw shaft 14. The fastening screw shaft 14 is sandwiched between a base member 10 and a pressing member 12. The steel pipe or the like is held and fixed between the base member 10 and the pressing member 12 by being fitted to the forked portion 12a of the pressing member 12 and pressing the pressing member 12 toward the base member 10 with a nut 15. It is.

１６はコ形クランプ１とパイプクランプ２とを連結する断面長方形の角柱状棒状体利用の連結用軸体であって、その短辺側の厚さが前記Ｌ形貫通孔９の巾より若干小さく、外端には、角軸部１７と当該角軸部１７から突出する螺軸部１８が一体に設けられ、更に外端近傍位置の長辺側両側面に、コ形本体６のＬ形貫通孔９を有する角部の内側面（突曲部８の内側面）に近接する抜け止め用ピン１９が同心状に突設されている。 Reference numeral 16 denotes a connecting shaft body that uses a rectangular rod-like body having a rectangular cross section for connecting the U-shaped clamp 1 and the pipe clamp 2, and the thickness on the short side thereof is slightly smaller than the width of the L-shaped through hole 9. The outer end is integrally provided with a square shaft portion 17 and a screw shaft portion 18 projecting from the angular shaft portion 17, and the L-shaped through-hole of the U-shaped main body 6 is formed on both side surfaces on the long side near the outer end. A retaining pin 19 that is close to the inner side surface of the corner having the hole 9 (inner side surface of the bent portion 8) is provided concentrically.

前記連結用軸体１６をコ形本体６の内側からＬ形貫通孔９に挿通して角軸部１７と螺軸部１８をＬ形貫通孔９から外側に突出させ、角軸部１７に支持座板２１の角孔２０を嵌合させることにより、コ形本体６から突出する連結用軸体１６に支持座板２１を回転不能に支持させている。このとき角軸部１７は支持座板２１の角孔２０からは突出しておらず、螺軸部１８のみが支持座板２１から突出している。この支持座板２１は矩形状のもので、その隣り合う２つの角部の内側に貫通孔２２ａ，２２ｂが設けられている。一方、パイプクランプ２のベース部材１０には、前記螺軸部１８に嵌合させる貫通孔２３と、支持座板２１の２つの貫通孔２２ａ，２２ｂに嵌合させることが出来る２つの突起２４ａ，２４ｂが設けられている。 The connecting shaft body 16 is inserted into the L-shaped through hole 9 from the inside of the U-shaped main body 6, and the rectangular shaft portion 17 and the screw shaft portion 18 are projected outward from the L-shaped through hole 9 and supported by the rectangular shaft portion 17. By fitting the square hole 20 of the seat plate 21, the support seat plate 21 is non-rotatably supported by the connecting shaft 16 protruding from the U-shaped main body 6. At this time, the square shaft portion 17 does not protrude from the square hole 20 of the support seat plate 21, and only the screw shaft portion 18 protrudes from the support seat plate 21. The support seat plate 21 has a rectangular shape, and through holes 22a and 22b are provided inside two adjacent corners. On the other hand, the base member 10 of the pipe clamp 2 has a through hole 23 fitted into the screw shaft portion 18 and two protrusions 24a that can be fitted into the two through holes 22a and 22b of the support seat plate 21. 24b is provided.

而して、支持座板２１から突出している連結用軸体１６の螺軸部１８に貫通孔２３を嵌合させたパイプクランプ２のベース部材１０を、２つの突起２４ａ，２４ｂを支持座板２１側の２つの貫通孔２２ａ，２２ｂに嵌合させて支持座板２１に当接させ、この状態で、当該ベース部材１０の貫通孔２３から突出している螺軸部１８に圧縮バネ２５を嵌合させると共に、当該圧縮バネ２５の外側で螺軸部１８にナット２６を螺合して、連結用軸体１６にパイプクランプ２を取り付けている。尚、圧縮バネ２５は、基本的には圧縮コイルバネでも良いが、ナット２６と共にベース部材１０の内側凹部に収める必要があるところから、軸方向の厚さが出来る限り薄いものが望ましい。従ってこの実施例では、図８に示すように、支持座板２１に当接する環状座部２５ａの内周辺から斜め内側に立ち上がる周方向多数のバネ片２５ｂを備えた皿バネ状のものを使用しているが、例えば、環状平板を周方向に凹凸をつけるように波形にプレス加工させたものなど、従来周知の各種の環状圧縮バネが利用出来る。ナット２６は、ベース部材１０との間で圧縮バネ２５を圧縮変形させない程度に挟んだ状態で螺軸部１８にカシメなどにより固定しておくのが望ましい。 Thus, the base member 10 of the pipe clamp 2 in which the through-hole 23 is fitted into the screw shaft portion 18 of the connecting shaft 16 projecting from the support seat plate 21 is used, and the two projections 24a and 24b are used as the support seat plate. The compression spring 25 is fitted to the screw shaft portion 18 protruding from the through hole 23 of the base member 10 in this state by being fitted into the two through holes 22a and 22b on the 21 side and brought into contact with the support seat plate 21. At the same time, a nut 26 is screwed onto the screw shaft portion 18 outside the compression spring 25, and the pipe clamp 2 is attached to the connecting shaft body 16. The compression spring 25 may basically be a compression coil spring, but it is desirable that the axial thickness is as thin as possible because it needs to be housed in the inner recess of the base member 10 together with the nut 26. Therefore, in this embodiment, as shown in FIG. 8, a disc spring-like one having a large number of circumferentially extending spring pieces 25b rising obliquely inward from the inner periphery of the annular seat portion 25a contacting the support seat plate 21 is used. However, for example, various well-known annular compression springs such as those obtained by pressing an annular flat plate into a corrugated shape so as to be uneven in the circumferential direction can be used. It is desirable that the nut 26 is fixed to the screw shaft portion 18 by caulking or the like with the compression spring 25 being sandwiched between the nut 26 and the base member 10 so as not to compress and deform.

上記構成のパイプクランプ装置では、コ形クランプ１に連結用軸体１６、支持座板２１、圧縮バネ２５、及びナット２６を介して取り付けられたパイプクランプ２は、連結用軸体１６に対して当該連結用軸体１６の周りに回転することが、コ形クランプ１側の嵌合部である支持座板２１の２つの貫通孔２２ａ，２２ｂと、パイプクランプ２側の嵌合部であるベース部材１０の２つの突起２４ａ，２４ｂとの嵌合により阻止されており、当該パイプクランプ２のベース部材１０と押さえ部材１２との間で把持固定される鋼管の向きが、コ形クランプ１のＬ形貫通孔９内を９０度の範囲で揺動可能な連結用軸体１６の揺動方向と平行な向き（抜け止め用ピン１９と直交する向き）となるように、前記嵌合部（貫通孔２２ａ，２２ｂと突起２４ａ，２４ｂ）が設けられている。勿論、ベース部材１０の２つの突起２４ａ，２４ｂを支持座板２１側の２つの貫通孔２２ａ，２２ｂに嵌合させたとき、パイプクランプ２で把持固定される鋼管の向きが、連結用軸体１６の揺動方向に対して直交する向き（抜け止め用ピン１９と平行な向き）となるように構成することも可能であるし、支持座板２１側の２つの貫通孔２２ａ，２２ｂを９０度位相を変えて二組設け、コ形クランプ１に対してパイプクランプ２を上記何れの向きにも取り付けることが出来るように構成することも可能である。 In the pipe clamp device having the above-described configuration, the pipe clamp 2 attached to the U-shaped clamp 1 via the coupling shaft 16, the support seat plate 21, the compression spring 25, and the nut 26 is connected to the coupling shaft 16. Rotating around the connecting shaft 16 is the two through holes 22a and 22b of the support seat plate 21 that is the fitting portion on the U-shaped clamp 1 side and the base that is the fitting portion on the pipe clamp 2 side. The direction of the steel pipe which is blocked by the fitting between the two protrusions 24a and 24b of the member 10 and is held and fixed between the base member 10 and the pressing member 12 of the pipe clamp 2 is L of the U-shaped clamp 1. The fitting portion (penetration) is formed so as to be in a direction parallel to the swinging direction of the connecting shaft body 16 that can swing in the shape of the through hole 9 within a range of 90 degrees (a direction orthogonal to the retaining pin 19). Holes 22a, 22b and protrusions 24a, 4b) is provided. Of course, when the two protrusions 24a and 24b of the base member 10 are fitted into the two through holes 22a and 22b on the support seat plate 21 side, the orientation of the steel pipe held and fixed by the pipe clamp 2 depends on the connecting shaft body. It is also possible to configure such that the direction is perpendicular to the swinging direction of 16 (the direction parallel to the retaining pin 19), and the two through holes 22a and 22b on the support seat plate 21 side are provided with 90. It is also possible to provide two pairs with different degrees of phase so that the pipe clamp 2 can be attached to the U-shaped clamp 1 in any of the above directions.

上記構成のパイプクランプ装置は、次のように使用することが出来る。即ち、パイプクランプ２に把持固定させる鋼管の向きを、コ形クランプ１が嵌合する鉄骨などのフランジ部に対して平行な向きにするときは、図１及び図２に示すように、パイプクランプ２を、コ形本体６の側壁部３，５間の角部を中心にして連結用軸体１６と共に側壁部３の方へ回動させ、連結用軸体１６を側壁部５における突曲部８の内側凹部内に嵌合させる。又、パイプクランプ２に把持固定させる鋼管の向きを、コ形クランプ１が嵌合する鉄骨などのフランジ部に対して垂直な向きにするときは、図１に仮想線で示すように、パイプクランプ２を、コ形本体６の側壁部３，５間の角部を中心にして連結用軸体１６と共に側壁部５の方へ回動させ、連結用軸体１６を側壁部３における突曲部８の内側凹部内に嵌合させる。係る状態で、鉄骨などのフランジ部にコ形本体６を嵌合させると共に締結用螺軸７を螺進させ、当該締結用螺軸７の先端皿バネ７ａとコ形本体６の側壁部３との間で当該フランジ部を挟持固定する。 The pipe clamp device having the above configuration can be used as follows. That is, when the direction of the steel pipe to be gripped and fixed to the pipe clamp 2 is made parallel to the flange portion such as a steel frame with which the U-shaped clamp 1 is fitted, as shown in FIGS. 2 is rotated about the corner between the side wall portions 3 and 5 of the U-shaped main body 6 together with the connecting shaft 16 toward the side wall 3, and the connecting shaft 16 is bent at the side wall 5. 8 is fitted into the inner recess. When the direction of the steel pipe to be gripped and fixed to the pipe clamp 2 is set to be perpendicular to the flange portion such as a steel frame with which the U-shaped clamp 1 is fitted, as shown by the phantom line in FIG. 2 is rotated toward the side wall portion 5 together with the connecting shaft body 16 around the corner between the side wall portions 3 and 5 of the U-shaped main body 6, and the connecting shaft body 16 is bent at the side wall portion 3. 8 is fitted into the inner recess. In this state, the U-shaped main body 6 is fitted into a flange portion such as a steel frame and the fastening screw shaft 7 is screwed, and the tip disc spring 7a of the fastening screw shaft 7 and the side wall portion 3 of the U-shaped main body 6 The flange portion is clamped and fixed between.

この結果、連結用軸体１６は、コ形本体６の側壁部５又は側壁部３における突曲部８の内側面と鉄骨などのフランジ部との間で挟持され、パイプクランプ２は当該連結用軸体１６を介してコ形クランプ１に所定向きで固定されることになるので、当該パイプクランプ２のベース部材１０と押さえ部材１２との間に鋼管を挟み込むと共に、締結用螺軸１４と締結用ナット１５とで押さえ部材１２をベース部材１０側に締結することにより、当該パイプクランプ２とコ形クランプ１とを介して鋼管を鉄骨などのフランジ部に所定向きで固定することが出来る。 As a result, the connecting shaft body 16 is sandwiched between the inner surface of the curved portion 8 in the side wall portion 5 or the side wall portion 3 of the U-shaped main body 6 and a flange portion such as a steel frame, and the pipe clamp 2 is used for the connection. Since it is fixed to the U-shaped clamp 1 through the shaft 16 in a predetermined direction, the steel pipe is sandwiched between the base member 10 and the pressing member 12 of the pipe clamp 2 and is fastened to the fastening screw shaft 14. By fastening the pressing member 12 to the base member 10 side with the nut 15, the steel pipe can be fixed to a flange portion such as a steel frame in a predetermined direction via the pipe clamp 2 and the U-shaped clamp 1.

尚、上記のように本発明のパイプクランプ装置により鋼管を鉄骨などのフランジ部に取り付けるとき、鋼管に作用する外力によってパイプクランプ１には、連結用軸体１６の周りの回転力が作用するときがある。この回転力によって、パイプクランプ２側の嵌合部である突起２４ａ，２４ｂがコ形クランプ１側の嵌合部である貫通孔２２ａ，２２ｂから、圧縮バネ２５の付勢力に抗して支持座板２１からベース部材１０が離間する方向の移動を伴って離脱するのを極力抑えるため、前記突起２４ａ，２４ｂは、図３及び図５に示すように、ベース部材１０に予め穿設した貫通孔の周囲を片側に筒状に突出させるバーリング加工により形成した筒状突起とし、支持座板２１とベース部材１０との間に連結用軸体１６の螺軸部１８の周りの相対回転力が作用しても、支持座板２１に対してベース部材１０を螺軸部１８の軸方向に押し出す分力が作用しないように構成するのが望ましい。 When the steel pipe is attached to the flange portion such as a steel frame by the pipe clamp device of the present invention as described above, when the rotational force around the connecting shaft 16 is applied to the pipe clamp 1 by the external force acting on the steel pipe. There is. By this rotational force, the protrusions 24a and 24b which are fitting portions on the pipe clamp 2 side are supported from the through holes 22a and 22b which are fitting portions on the U-shaped clamp 1 side against the urging force of the compression spring 25. In order to suppress the separation of the base member 10 from the plate 21 with movement in the direction away from the plate 21 as much as possible, the protrusions 24a and 24b are through holes formed in the base member 10 in advance as shown in FIGS. A cylindrical projection formed by a burring process in which the periphery of the connecting member 16 is protruded in a cylindrical shape on one side, and a relative rotational force around the screw shaft portion 18 of the connecting shaft body 16 acts between the support seat plate 21 and the base member 10. Even so, it is desirable that the component force that pushes the base member 10 in the axial direction of the screw shaft portion 18 does not act on the support seat plate 21.

上記構成のパイプクランプ装置をパイプクランプ遊転型として使用するときは、上記のようにコ形クランプ１を鉄骨などのフランジ部に挟持固定すると共にパイプクランプ２を鋼管に把持固定した状態で、当該鋼管を利用してパイプクランプ２をコ形クランプ１から連結用軸体１６の軸方向に引き離すように操作し、図５に示すように、ベース部材１０とナット２６との間の圧縮バネ２５を圧縮変形させて、コ形クランプ１側の支持座板２１に対してパイプクランプ２のベース部材１０を離間移動させ、パイプクランプ２側の嵌合部である突起２４ａ，２４ｂをコ形クランプ１側の嵌合部である貫通孔２２ａ，２２ｂから離脱させる。この結果、パイプクランプ２は、コ形クランプ１側の連結用軸体１６の螺軸部１８の周りに回転させることが出来る状態になるので、そのまま鋼管をパイプクランプ２と共に連結用軸体１６の螺軸部１８の周りに回転させ、任意の角度に調整することが出来る。 When the pipe clamp device having the above configuration is used as a pipe clamp free-rolling type, the U-shaped clamp 1 is clamped and fixed to a flange portion such as a steel frame and the pipe clamp 2 is held and fixed to a steel pipe as described above. Using the steel pipe, the pipe clamp 2 is operated so as to be pulled away from the U-shaped clamp 1 in the axial direction of the connecting shaft 16, and as shown in FIG. 5, the compression spring 25 between the base member 10 and the nut 26 is moved. By compressing and deforming, the base member 10 of the pipe clamp 2 is moved away from the support seat plate 21 on the U-shaped clamp 1 side, and the projections 24a and 24b which are fitting portions on the side of the pipe clamp 2 are moved to the U-shaped clamp 1 side. It is made to detach | leave from the through-holes 22a and 22b which are the fitting parts. As a result, the pipe clamp 2 can be rotated around the screw shaft portion 18 of the connecting shaft 16 on the U-shaped clamp 1 side. It can be rotated around the screw shaft portion 18 and adjusted to an arbitrary angle.

この鋼管の他の箇所を鉄骨などのフランジ部に本発明のパイプクランプ装置を利用して固定するときは、当該鋼管の所定位置にパイプクランプ２を把持固定し、このパイプクランプ２に対してコ形クランプ１を連結用軸体１６の軸方向に引っ張り、前記のようにパイプクランプ２とコ形クランプ１とを連結用軸体１６の螺軸部１８の周りに相対回転自在な状態に切り換え、係る状態でコ形クランプ１を鉄骨などのフランジ部に嵌合させることが出来る向きに回転させて、当該鉄骨などのフランジ部に嵌合固定させれば良い。尚、コ形クランプ１とパイプクランプ２とを互いに離間させるように作用させた操作力を解除したとき、パイプクランプ２側の嵌合部である突起２４ａ，２４ｂの先端がコ形クランプ１側の支持座板２１の表面に圧接することになる。 When the other portion of the steel pipe is fixed to a flange portion such as a steel frame using the pipe clamp device of the present invention, the pipe clamp 2 is held and fixed at a predetermined position of the steel pipe, and the pipe clamp 2 is connected to the pipe clamp 2. The shape clamp 1 is pulled in the axial direction of the connecting shaft body 16, and the pipe clamp 2 and the U-shaped clamp 1 are switched to a state in which they can be relatively rotated around the screw shaft portion 18 of the connecting shaft body 16, as described above. In this state, the U-shaped clamp 1 may be rotated in a direction in which it can be fitted to a flange such as a steel frame, and fitted and fixed to the flange such as the steel frame. When the operating force that causes the U-shaped clamp 1 and the pipe clamp 2 to be separated from each other is released, the tips of the protrusions 24a and 24b that are fitting portions on the side of the pipe clamp 2 are on the U-shaped clamp 1 side. The surface of the support seat plate 21 is pressed.
