Description

この発明は、配管を拘束しつつ支持するための配管固定装置に関する。   The present invention relates to a pipe fixing device for supporting a pipe while restraining it.

発電設備などに備えられる配管が、自重、機械荷重、流体振動、熱膨張及び地震などの外力を受けたときに、いずれの方向へも変位しないように固定する配管固定装置として、特許文献１に記載されたライニング管のクランプ装置が知られている。この装置は、両側部に締付片を張り出させた半円形断面形状の一対のクランプ具をライニング管の両側外面に当てて、締付片に通したボルトにて締め付けてクランプするものである。クランプ具の内面には、円周方向の溝と突起とからなる凹凸を形成して、ライニング管の軸方向の移動に大きな摩擦力を付与している。
また、配管を間に挟んで固定する第１及び第２の把持部材を具備し、これら把持部材の断面円弧状の把持溝に左右回転方向の異なる二条の螺旋溝を形成したものが知られている（特許文献２）。 Patent Document 1 discloses a pipe fixing device that fixes a pipe provided in a power generation facility so as not to be displaced in any direction when it receives external forces such as its own weight, mechanical load, fluid vibration, thermal expansion, and earthquake.

上記従来の装置においては、上下の両把持部材を配管に直接あてがい、ボルト等の締付けによって固定するので、 配管の外径公差に対応させるため、配管の外周面に沿った両把持部材が配管の外径より大きな円弧を形成する。このため実質的に両把持部材の上下頂部を中心とする二箇所だけが接触する構造となっている。この場合、両把持部材をボルトによって締め付けるため、両把持部材が配管に与える応力が集中してしまう。また、このような二箇所で接触する構造では、接触抵抗が小さく配管の軸方向の変位、配管の円周方向の変位及び両把持部材の対向方向の中心軸周りのモーメントを容易に許容してしまうため、確実な固定が困難である。
そこで、この出願に係る発明は、配管との接触位置を四点として、固定時の応力を低減させると共により強固に固定する配管固定装置を提供することを課題としている。 In the above conventional apparatus, the upper and lower gripping members are directly attached to the pipe and fixed by tightening bolts or the like. Therefore, in order to cope with the outer diameter tolerance of the pipe, the two gripping members along the outer peripheral surface of the pipe are connected to the pipe. An arc larger than the outer diameter is formed. For this reason, it has the structure which only two places centering on the up-and-down top part of both holding members contact substantially. In this case, since both the gripping members are tightened with the bolts, the stress exerted on the pipe by the both gripping members is concentrated. In addition, in such a structure where contact is made at two places, the contact resistance is small, and the displacement in the axial direction of the pipe, the displacement in the circumferential direction of the pipe, and the moment around the central axis in the opposing direction of both gripping members are easily allowed. For this reason, it is difficult to reliably fix.
Then, the invention concerning this application makes it a subject to provide the piping fixing device which fixes more firmly while reducing the stress at the time of fixing by making the contact position with piping into four points.

上記課題を解決するため、この出願に係る発明においては、配管Ｐを支持する支持部材２に固定される第１の把持部材３と、この第１の把持部材３との間に配管Ｐを挟む第２の把持部材４とを具備させ、これら両把持部材３，４に配管Ｐの外周面を受け入れる把持溝６，９を設け、両把持部材３，４をボルト５で締結する配管固定装置１を構成する。把持溝６，９は、受け入れた配管Ｐに周方向に異なる二箇所でそれぞれ接触する接触部Ｃ１，Ｃ２を設けた。
接触部Ｃ１，Ｃ２は、把持溝の両側縁部から底部に向かう一対の傾斜面６ｂ，９ｂにそれぞれ配置した。
傾斜面６ｂ，９ｂは、断面略円弧状に湾曲する外側膨らみの湾曲面に形成した。
把持溝６，９の底部及び縁部は切削により断面略円弧状に形成し、接触部Ｃ１，Ｃ２は底部及び縁部の境界を形成する稜線で形成した。
把持溝２０，２１は一対の平坦な傾斜面を有する断面略三角形状の溝に形成した。
両把持部材２２，２３は、湾曲した鋼板材で構成した。
第１の把持部材３及び第２の把持部材４には、互いに係合して、配管の軸線方向の変位時の第１の把持部材の滑りに伴う第２の把持部材の相対変位を阻止する係合部１４をそれぞれ具備させた。 In order to solve the above problem, in the invention according to this application, the pipe P is sandwiched between the first gripping member 3 fixed to the support member 2 that supports the pipe P and the first gripping member 3. A pipe fixing device 1 provided with a second gripping member 4, provided with gripping grooves 6, 9 for receiving the outer peripheral surface of the pipe P in the both gripping members 3, 4, and fastening both the gripping members 3, 4 with bolts 5. Configure. The gripping grooves 6 and 9 are provided with contact portions C1 and C2 that respectively contact the received pipe P at two different locations in the circumferential direction.
The contact portions C1 and C2 were respectively disposed on the pair of inclined surfaces 6b and 9b from the both side edges of the gripping groove toward the bottom.
The inclined surfaces 6b and 9b were formed on curved surfaces of outer bulges that are curved in a substantially arc shape in cross section.
The bottoms and edges of the gripping grooves 6 and 9 were formed in a substantially arc shape in cross section by cutting, and the contact parts C1 and C2 were formed by ridge lines forming the boundary between the bottom and edges.
The gripping grooves 20 and 21 were formed in a substantially triangular groove having a pair of flat inclined surfaces.
Both gripping members 22 and 23 are made of curved steel plate materials.
The first gripping member 3 and the second gripping member 4 are engaged with each other to prevent relative displacement of the second gripping member due to slippage of the first gripping member when the pipe is displaced in the axial direction. Each of the engaging portions 14 was provided.

この出願に係る発明の装置によれば、配管との接触位置を四点としたので、配管に与える応力を低減することができ、配管への負担を減らすことができるし、配管の着座性能が安定し二点の接触に比べて配管の軸方向の変位、円周方向の変位及び両把持部材の対向方向の中心軸周りのモーメントに対して大きな接触抵抗を与え、強固に固定することができる。   According to the apparatus of the invention relating to this application, since the contact position with the piping is set to four points, the stress applied to the piping can be reduced, the burden on the piping can be reduced, and the seating performance of the piping is reduced. Compared to two points of contact, it provides a large contact resistance against the axial displacement of the pipe, the circumferential displacement, and the moment around the central axis in the opposite direction of both gripping members, and can be firmly fixed. .

図面を参照してこの発明の実施の形態を説明する。
図１ないし図４において、配管固定装置１は、配管Ｐを支持する支持部材２と、この支持部材２に固定される第１の把持部材３と、この第１の把持部材３との間に配管Ｐを挟んで第１の把持部材３にボルト５で締め付けられる第２の把持部材４とを具備する。以下、便宜上、配管Ｐに対して、支持部材２側を「下方」、その反対側を「上方」として説明するが、配管の延長方向によって、現実の上方、下方とは必ずしも一致しない。 Embodiments of the present invention will be described with reference to the drawings.

And a second gripping member 4 that is fastened to the first gripping member 3 with a bolt 5 across the pipe P. Hereinafter, for the sake of convenience, the support member 2 side will be described as “downward” and the opposite side as “upward” with respect to the pipe P.

第１の把持部材３は、角パイプやＨ型鋼材などで構成される既設の支持架構である支持部材２に溶接やボルト接合などの周知の固定方法により固着される。第１の把持部材３は直方形状の鋼材からなり、配管Ｐのほぼ半部を受け入れる把持溝６と、第２の把持部材４にボルト止めする接続部７とを備えている。把持溝６は、外側膨らみに湾曲した断面略円弧状の底部６ａと、縁部から底部６ａに向かう外側膨らみに湾曲した断面略円弧状の一対の傾斜面６ｂとで形成される。傾斜面６ｂには、配管Ｐとの接触部Ｃ１を有する。接続部７には、第２の把持部材４との対向方向に四本のボルト５を挿通させるために軸線方向に間隔をおいた四つのボルト穴８をそれぞれ備えている。   The first gripping member 3 is fixed to a support member 2 that is an existing support frame composed of a square pipe, an H-shaped steel material, or the like by a known fixing method such as welding or bolt joining. The first gripping member 3 is made of a rectangular steel material, and includes a gripping groove 6 that receives substantially half of the pipe P and a connection portion 7 that is bolted to the second gripping member 4. The grip groove 6 is formed by a bottom portion 6a having a substantially arc-shaped cross section curved to the outer bulge and a pair of inclined surfaces 6b having a substantially arc-shaped section curved to the outer bulge from the edge toward the bottom portion 6a. The inclined surface 6b has a contact portion C1 with the pipe P. The connecting portion 7 is provided with four bolt holes 8 spaced in the axial direction so that the four bolts 5 are inserted in the direction facing the second gripping member 4.

第２の把持部材４は直方形状の鋼材からなり、第１の把持部材３の把持溝６に対向し配管Ｐのほぼ半部を受け入れる把持溝９と、第１の把持部材３にボルト止めする接続部１０とを具備する。把持溝９は、把持溝６と同様に、外側膨らみに湾曲した断面略円弧状の底部９ａと、縁部から底部９ａに向かう外側膨らみに湾曲した断面略円弧状の一対の傾斜面９ｂとで形成される。傾斜面９ｂには、配管Ｐとの接触部Ｃ２を有する。接続部１０には、第１の把持部材３との対向方向に四本のボルト５を挿通させるために軸線方向に間隔をおいた四つのボルト孔１１をそれぞれ備えている。   The second gripping member 4 is made of a rectangular steel material, and is bolted to the first gripping member 3 and the gripping groove 9 that faces the gripping groove 6 of the first gripping member 3 and receives almost half of the pipe P. And a connection unit 10. As in the case of the gripping groove 6, the grip groove 9 includes a bottom portion 9a having a substantially arc-shaped cross section curved to the outer bulge, and a pair of inclined surfaces 9b having a substantially arc-shaped section curved to the outer bulge from the edge toward the bottom portion 9a. It is formed. The inclined surface 9b has a contact portion C2 with the pipe P. The connecting portion 10 is provided with four bolt holes 11 spaced in the axial direction in order to allow the four bolts 5 to be inserted in the direction facing the first gripping member 3.

第１，第２の把持部材３，４の相互間にわたる係合部１４は、図１，図２に示すように、接合面１２，１３に形成されたキー溝１５，１６と、これらに嵌合する係合キー１７とを具備する。キー溝１５，１６は、接合面１２，１３の中央部に把持状態の配管Ｐの軸線直交方向に設けられ、第１，第２の把持部材３，４の側面から把持溝６，９の近傍位置で終結している。キー１７は、第１の把持部材３と第２の把持部材４との結合状態において、キー溝１５，１６間に差し込まれるように四角柱状をなし、先端部が先細りの円弧状に形成されている。   As shown in FIGS. 1 and 2, the engaging portion 14 between the first and second gripping members 3 and 4 is fitted with key grooves 15 and 16 formed on the joint surfaces 12 and 13, and fitted into these. And a mating engagement key 17. The key grooves 15 and 16 are provided in the center part of the joint surfaces 12 and 13 in the direction orthogonal to the axis of the pipe P in the grip state, and in the vicinity of the grip grooves 6 and 9 from the side surfaces of the first and second grip members 3 and 4. Ends in position. The key 17 is formed in a quadrangular prism shape so as to be inserted between the key grooves 15 and 16 in the coupled state of the first gripping member 3 and the second gripping member 4, and the tip portion is formed in a tapered arc shape. Yes.

この配管固定装置１は、配管Ｐを把持部材３，４により上下に挟み込み、ボルト５を規定のトルクで締結することにより、把持溝６，９の傾斜面６ｂ，９ｂの接触部Ｃ１，Ｃ２でそれぞれ配管Ｐに接触する。このため、把持溝６，９が配管Ｐの外周面に均一に密着することなく、実質的に四箇所で配管Ｐを固定することになり、従来のような限定された二箇所で接触する場合に比較して配管Ｐに与える応力を低減することができ、また配管Ｐの軸方向及び周方向の変位に対して大きな接触抵抗を与えることになる。さらに両把持部材３，４を上下に貫通する軸周りのモーメントに対し、強力に固定できることになる。把持部材３，４をボルト５で締結後、キー１７をキー溝１５，１６内に差し込めば、把持部材３，４間の軸線方向の相対変位が阻止され、配管Ｐを確実に固定する。   In this pipe fixing device 1, the pipe P is sandwiched up and down by the gripping members 3 and 4, and the bolt 5 is fastened with a specified torque, whereby the contact portions C1 and C2 of the inclined surfaces 6b and 9b of the gripping grooves 6 and 9 are obtained. Each is in contact with the pipe P. For this reason, the gripping grooves 6 and 9 do not uniformly adhere to the outer peripheral surface of the pipe P, and the pipe P is substantially fixed at four places, and contact is made at two limited places as in the prior art. As compared with the above, the stress applied to the pipe P can be reduced, and a large contact resistance is given to the displacement of the pipe P in the axial direction and the circumferential direction. Further, it is possible to strongly fix the moment around the axis passing through both the gripping members 3 and 4 up and down. If the key 17 is inserted into the key grooves 15 and 16 after the gripping members 3 and 4 are fastened with the bolts 5, relative displacement in the axial direction between the gripping members 3 and 4 is prevented, and the pipe P is securely fixed.
