ところで、このような管状体には、該管状体を接続対象等の取付対象に固定するボルトが挿通されるボルト孔を設けた取付部が設けられる場合がある。このような場合に、上記のような互いに接合されるフランジを設けた構成とすれば、取付対象側のボルトが挿通されるボルト孔やボルトが締め付けられる雌ねじ穴の位置の制約等によっては、このフランジが取付部やボルトを締結する工具に干渉する場合が考えられる。 By the way, such a tubular body may be provided with a mounting portion provided with a bolt hole through which a bolt for fixing the tubular body to a mounting target such as a connection target is inserted. In such a case, if the structure is provided with flanges that are joined to each other as described above, depending on the restriction of the position of the bolt hole through which the bolt on the mounting target side is inserted and the female screw hole to which the bolt is tightened, this It is conceivable that the flange interferes with the tool for fastening the mounting portion and the bolt.

本発明は、上記実情に鑑みなされたものであり、径方向に分割された半管状部同士を接合する接合突部を設けながらも、接合突部によるボルトの締結性の低下を抑制し得る管状体を提供することを目的としている。 The present invention has been made in view of the above circumstances, and has a tubular shape capable of suppressing a decrease in fastening performance of a bolt due to a joining projection while providing a joining projection for joining semi-tubular portions divided in the radial direction. The purpose is to provide a body.

前記目的を達成するために、本発明に係る管状体は、径方向に分割された２つの半管状部同士が接合され、取付対象に固定するボルトが挿通されるボルト孔が設けられた取付部を有した管状体であって、前記２つの半管状部の互いに接合された縁部には、径方向に突出する接合突部が設けられており、これら半管状部の接合突部が突き合わせられて形成される接合部の一部を、前記取付部と一体としたことを特徴とする。 In order to achieve the above object, the tubular body according to the present invention has two semi-tubular portions divided in the radial direction joined together, and a mounting portion provided with a bolt hole through which a bolt to be fixed to the mounting target is inserted. The two semi-tubular portions are joined to each other at the edge of the two semi-tubular portions, which are provided with joint protrusions protruding in the radial direction, and the joint protrusions of these semi-tubular portions are abutted against each other. A part of the joint formed is integrated with the mounting part.

本発明によれば、径方向に分割された２つの半管状部の互いに接合された縁部に設けられた接合突部同士が突き合わせられて接合部が形成される。従って、このような接合突部を設けていないものと比べて接合強度を向上させることができる。また、接合部の一部を、ボルト孔を設けた取付部と一体としている。従って、例えば、取付部近傍の別位置に接合部の一部が配されるようなものと比べて、ボルトを締結する工具に接合部が干渉するようなことを抑制することができる。また、例えば、工具に干渉しないように接合部を軸心側に迂回させるような必要が生じず、流路が狭められるようなことを抑制することができる。 According to the present invention, the joining projections provided at the joined edges of the two semi-tubular parts divided in the radial direction are abutted to form a joined part. Accordingly, the bonding strength can be improved as compared with the case where such a bonding protrusion is not provided. Further, a part of the joint portion is integrated with the attachment portion provided with the bolt hole. Therefore, for example, it is possible to suppress the joint portion from interfering with the tool for fastening the bolt, as compared with a case where a part of the joint portion is disposed at another position near the attachment portion. Further, for example, it is not necessary to detour the joint to the axial center side so as not to interfere with the tool, and it is possible to suppress the narrowing of the flow path.

本発明においては、前記取付部と一体とされた前記接合部の一部は、前記２つの半管状部の周方向縁部に軸方向に延びるように設けられた接合突部が突き合わせられて形成されていてもよい。

本発明によれば、第１半管状部の少なくとも軸方向一端部が当該管状体の一端部を構成するように管状に一体的に形成されているので、管状体の一端部の開口周縁部が第１半管状部によって一体的に形成されることとなる。これにより、例えば、管状体の一端部の開口周縁部が第１半管状部と第２半管状部との接合によって形成されたものと比べて、一端部の開口側の面における段差等の発生を抑制することができる。
また、第１半管状部の管状とされた一端部の接合突部とこれに対向される他方の第２半管状部の軸方向一端部の接合突部とが突き合わせられて形成される端部接合部を、取付部と一体とすることができる。従って、管状体の軸方向一端部の近傍に取付対象のボルト孔や雌ねじ穴が設けられているような場合に好適な態様となる。 In the present invention, at least one axial end portion of one of the two semi-tubular portions is integrally formed in a tubular shape so as to constitute one end portion of the tubular body, One end of the first semi-tubular portion that is tubular and one end in the axial direction of the other second semi-tubular portion that opposes the one end are joined to each other to form an end joint. A part of the end joint portion may be integrated with the mounting portion.
According to the present invention, since at least one axial end portion of the first semi-tubular portion is integrally formed in a tubular shape so as to constitute one end portion of the tubular body, the opening peripheral edge portion of the one end portion of the tubular body is formed. The first semi-tubular portion is integrally formed. Thereby, for example, compared with the case where the opening peripheral edge portion of the one end portion of the tubular body is formed by joining the first semi-tubular portion and the second semi-tubular portion, a step or the like is generated on the opening side surface of the one end portion. Can be suppressed.
Further, an end portion formed by abutting a joining projection at one end of the first semi-tubular portion and an joining projection at one end in the axial direction of the other second semi-tubular portion facing each other. The joint portion can be integrated with the attachment portion. Therefore, this is a preferred embodiment in the case where a bolt hole or a female screw hole to be attached is provided in the vicinity of one axial end portion of the tubular body.

また、本発明においては、前記取付部のボルト孔は、当該取付部に埋込状に設けられた金属製の円筒状部材によって構成されていてもよい。
本発明によれば、ボルトの締結による取付部の破損等を抑制することができる。 Moreover, in this invention, the bolt hole of the said attachment part may be comprised by the metal cylindrical member provided in the said attachment part by embedding.
According to the present invention, it is possible to suppress damage to the mounting portion due to fastening of the bolt.

本実施形態に係る管状体１は、上述のような構成としたことで、径方向に分割された半管状部１０，２０同士を接合する接合突部（第１周縁接合突部）１２，２２を設けながらも、第１周縁接合突部１２，２２によるボルト９の締結性の低下を抑制することができる。
つまり、径方向に分割された２つの半管状部１０，２０の第１周縁接合突部１２，２２同士が突き合わせられて第１周縁接合部２が形成される。従って、このような第１周縁接合突部１２，２２を設けていないものと比べて接合強度を向上させることができる。また、本実施形態では、２つの半管状部１０，２０の互いに突き合わせられる縁部（周方向両縁部及び軸方向両端縁部）の全体に亘って接合突部１２，１３，１６，１７，２２，２３，２６，２７を設けているので、接合強度をより効果的に向上させることができる。 Since the tubular body 1 according to the present embodiment has the above-described configuration, the joining protrusions (first peripheral joining protrusions) 12 and 22 that join the semi-tubular parts 10 and 20 that are divided in the radial direction.
