Description

この発明は、配管を拘束しつつ支持する配管固定装置に関し、特に配管を伝わる高周波振動を減衰させて拘束力を維持するものである。   The present invention relates to a pipe fixing device that supports a pipe while restraining it, and in particular, attenuates high-frequency vibration transmitted through the pipe to maintain the restraining force.

従来、配管を強固に固定する配管固定装置として特許文献１に記載の配管固定装置がある。この装置は、配管を支持する支持部材に固定される第１の把持部材と、この第１の把持部材との間に配管を挟む第２の把持部材と、両把持部材を締結するボルトとを具備する。両把持部材に配管の外周面を受け入れる把持溝を備え、さらに把持溝は、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を有する。接触部は、把持溝の両側縁部から底部に向かう一対の傾斜面にそれぞれ配置する。傾斜面は、断面略円弧状に湾曲する外側膨らみの湾曲面に形成する。
また、ボルトの緩みの防止手段として、皿ばね座金や舌片付座金等の回り止め対策の各種座金を用いたり、ハードロックナットと称する緩み止め対策を施したナットを用いる方法（非特許文献１参照）がある。 Conventionally, there is a pipe fixing apparatus described in Patent Document 1 as a pipe fixing apparatus that firmly fixes a pipe.

特開2013-080998号公報JP2013-080998A ハードロック工業株式会社のＷｅｂページ（ｈｔｔｐ：／／ｗｗｗ．ｈａｒｄｌｏｃｋ．ｃｏ．ｊｐ／ｈｌ／）に掲載の製品紹介記事Product introduction article posted on the website of Hard Rock Industry Co., Ltd. (http://www.hardlock.co.jp/hl/)

上記特許文献1に記載の装置においては、配管を挟み込む対向一対の把持部材で締結するボルトの締め付け強度を高めることで配管を拘束するが、配管に対する拘束性能の低下をもたらすボルトの緩みを防止する必要がある。これに対して非特許文献１に掲載されたボルト（ナット）などの緩み防止手段を配管固定装置に適用するとしても、配管からの振動が把持部材を介してボルト（ナット）に伝達されて、ボルトの緩みを生じることがあり、これに対して振動の伝達過程の最終位置のボルトの回り止めを行っても、ボルトに加わる振動的な外力による緩みを防止できない。被締結体である配管と把持部材とのなじみ（へたり）が振動により進行し、ボルトの軸力を維持することが困難になることもある。すなわち、配管系の中で生じる比較的高い振動数での微振動（高周波微振動）による配管の拘束手段においてボルトの回り止めのみに頼ることは継続的な配管の固定に十分でない。また、配管を通じて伝達される振動の配管系への拡散を防止する必要がある。
そこで、この出願に係る発明は、配管に生じる比較的高い振動数の微振動に対してボルトの緩みを防止して、継続的な配管の拘束性能を向上させると共に、配管系への振動の拡散を防止することを課題としている。 In the device described in Patent Document 1, the piping is restrained by increasing the tightening strength of the bolts fastened by the pair of opposed gripping members sandwiching the piping, but the bolts are prevented from loosening which causes a reduction in the restraining performance of the piping. There is a need. On the other hand, even if the loosening prevention means such as a bolt (nut) described in Non-Patent Document 1 is applied to the pipe fixing device, vibration from the pipe is transmitted to the bolt (nut) via the gripping member, In some cases, the bolt may be loosened. Even if the bolt is prevented from rotating at the final position in the vibration transmission process, the bolt cannot be prevented from loosening due to the vibrational external force applied to the bolt. The fitting (sagging) between the pipe to be fastened and the gripping member may proceed due to vibration, and it may be difficult to maintain the axial force of the bolt. That is, it is not sufficient for continuous fixing of the piping to rely only on the bolt detent in the piping restraining means by the micro vibration (high frequency micro vibration) at a relatively high frequency generated in the piping system. In addition, it is necessary to prevent diffusion of vibrations transmitted through the piping to the piping system.
Therefore, the invention according to this application prevents loosening of bolts against slight vibrations of a relatively high frequency generated in the piping, improves continuous piping restraint performance, and spreads vibration to the piping system. The challenge is to prevent this.

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との間に配管を挟む第２の把持部材４とを具備し、これら両把持部材３，４をボルト５で締結する配管固定装置１を構成する。両把持部材３，４は、配管Ｐに接触する接触部の配管Ｐの延長方向両端部に配管Ｐとの間に制振部材１６を介在させる制振部１２，１３を具備させる。
制振部１２，１３は、両把持部材３，４の配管延長方向両端部に突出し、制振部材１６が充填される断面半円弧状の収容溝１４ａ，１５ａを備えるホルダー片１４，１５を具備させる。 In order to solve the above problem, in the invention according to this application, the first gripping member 3 fixed to the support member 2 that supports the pipe P and the first gripping member 3 sandwich the pipe between the first gripping member 3 and the first gripping member 3. 2, and a pipe fixing device 1 for fastening both the holding members 3 and 4 with bolts 5 is provided. Both the gripping members 3 and 4 are provided with damping parts 12 and 13 for interposing a damping member 16 between the pipes P at both ends in the extending direction of the pipe P of the contact part that contacts the pipes P.
The damping parts 12, 13 include holder pieces 14, 15 provided with receiving grooves 14 a, 15 a having a semicircular arc cross section that protrudes at both ends in the pipe extending direction of the gripping members 3, 4 and is filled with the damping member 16. Let

この出願に係る発明の装置によれば、配管を挟み込む把持部材と配管との間に介在する制振部材により、配管から把持部材を通じてボルトに加わる振動に対して振動を抑制するので、ボルトへの振動の伝達が低減して、ボルトの緩みを防止することができ、継続的な配管の拘束性能を向上させることができる。また、配管系への振動の拡散を防止することができる。   According to the apparatus of the invention relating to this application, the vibration control member interposed between the gripping member sandwiching the pipe and the pipe suppresses vibration against vibration applied to the bolt from the pipe through the gripping member. Transmission of vibration can be reduced, bolt loosening can be prevented, and continuous piping restraint performance can be improved. Further, it is possible to prevent the vibration from diffusing into the piping system.

The first gripping member 3 is made of a rectangular steel material, and includes a gripping groove 6 having a semicircular cross section for receiving almost a half of the pipe P, and a connection portion 7 that is bolted to the second gripping member 4. . 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断面半円弧状の把持溝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。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, has a semicircular arc-shaped gripping groove 9 that opposes the gripping groove 6 of the first gripping member 3 and receives almost half of the pipe P, and the first gripping member 3 and a connecting portion 10 to be bolted. 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.

The damping units 12 and 13 include holder pieces 14 and 15 and damping members 16 held by the holder pieces 14 and 15. The holder pieces 14 and 15 have a semicircular cross-sectional shape in which one side of a continuous rectangular shape that projects from the end walls of the connection portions 7 and 10 of the first and second gripping members 3 and 4 receives the half of the pipe P It is made of steel material that is curved. The curved surfaces of the holder pieces 14, 15 are provided with receiving grooves 14 a, 15 a having a semicircular arc shape in cross section that form a gap with the received pipe P and are filled with the damping member 16. When the pipe 5 is sandwiched between the first and second gripping members 3 and 4 and the bolt 5 is tightened, the damping member 16 contacts the outer peripheral surface of the pipe P together with the gripping grooves 6 and 9, and the high frequency generated in the pipe P Damping the vibration. As the damping member 16, a member that performs a vibration-proofing operation such as a viscoelastic material (VEM = Visco Elastic Materials), an elastic mesh, or a vibration-proof rubber is applied.

この配管固定装置１は、配管Ｐを把持部材３，４で上下に挟み込み、ボルト５を規定のトルクで締結することにより、配管Ｐを拘束する。この状態で制振部１２，１３は、配管Ｐを受け入れて、把持溝６，９の内面と共に配管Ｐの外周面に接触する。配管Ｐに接続された設備機器から配管Ｐに伝達され、または配管Ｐ自体に生じた高周波振動が配管固定装置１に到達すると、配管Ｐに接触している制振部１２，１３の制振部材１６が振動を受けてこれを吸収し、本来配管Ｐに接触している把持部材３，４の把持溝６，９の内面から接続部７，１０を通じてボルト５に伝達されるべき振動を減衰させて、把持部材３，４のボルト５の緩みを抑制し、また配管固定装置１からさらに延びる配管Ｐに伝達される振動を減衰させ配管系の振動の拡散の低減させる。   The pipe fixing device 1 restrains the pipe P by sandwiching the pipe P up and down with gripping members 3 and 4 and fastening the bolt 5 with a specified torque. In this state, the damping units 12 and 13 receive the pipe P and contact the outer peripheral surface of the pipe P together with the inner surfaces of the gripping grooves 6 and 9. When high-frequency vibrations transmitted from the equipment connected to the pipe P to the pipe P or generated in the pipe P itself reach the pipe fixing device 1, the damping members of the damping parts 12 and 13 that are in contact with the pipe P 16 receives vibration and absorbs this, and attenuates vibration to be transmitted to the bolt 5 from the inner surfaces of the gripping grooves 6 and 9 of the gripping members 3 and 4 that are originally in contact with the pipe P through the connection portions 7 and 10. Thus, loosening of the bolts 5 of the gripping members 3 and 4 is suppressed, and vibration transmitted to the pipe P extending further from the pipe fixing device 1 is attenuated to reduce diffusion of vibration in the pipe system.
