Description
本発明は、管体に設けられたフランジ部の接合部構造の改良に関する。 The present invention relates to an improvement in a joint structure of a flange portion provided in a pipe body.
一般に、管等の接合部材及び被接合部材を接合する場合、接合部材及び被接合部材に夫々形成されたフランジ部等の接合片部に設けられた固定用孔部内を介して、ボルト及びナット等の固定部材により上記各接合片部を固定する接合部固定構造が使用されている。 In general, when joining a joining member such as a tube and a member to be joined, a bolt, a nut, or the like is provided through a fixing hole provided in a joining piece portion such as a flange portion formed on the joining member and the member to be joined. A joint fixing structure is used in which each of the joint pieces is fixed by the fixing member.
ここで、管の変形又は破断可能性を低減させるための接合部固定構造として、例えば特許文献１（特開２００５−１４７２４３号公報）に記載された接合部固定構造が提案されている。 Here, as a joint fixing structure for reducing the possibility of deformation or breakage of the pipe, for example, a joint fixing structure described in Patent Document 1 (Japanese Patent Laid-Open No. 2005-147243) has been proposed.
そして、特許文献１には、接合部材である管の端部に形成された接合片部であるフランジ部、及び、被接合部材であるバルブの接合片部であるフランジ部とが、同心円上に配設されたボルト及びナット等の複数の固定部材で固定され、前記固定部材の間で前記接合片部を取り囲み、かつ、バルブの接合片部であるフランジ部の端面に当接する内周面を有する複数の補強治具と、前記固定部材よりも内周側で前記補強治具に螺合されて前記管の接合片部に当接するボルトを有することを特徴とする接合部固定構造が開示されている。 And in patent document 1, the flange part which is the joining piece part formed in the edge part of the pipe | tube which is a joining member, and the flange part which is the joining piece part of the valve | bulb which is a to-be-joined member are on a concentric circle. An inner peripheral surface that is fixed by a plurality of fixing members such as bolts and nuts arranged, surrounds the joining piece portion between the fixing members, and contacts an end face of the flange portion that is a joining piece portion of the valve. There is disclosed a joint fixing structure comprising a plurality of reinforcing jigs and bolts that are screwed into the reinforcing jigs on the inner peripheral side of the fixing member and come into contact with the joint pieces of the pipe. ing.
上記接合部固定構造は、接合部材等である管の端部に形成された接合片部であるフランジ部と、バルブの接合片部であるフランジ部とが、同心円上に配設されたボルト及びナット等の複数の固定部材で固定され、さらにその固定部が補強治具により固定部材よりも内周側で締付けられるので、接合部に地震などによる大きな荷重が作用した場合でも接合片部であるフランジ部の変形又は破断可能性を低減させることができる。 The joint fixing structure includes a bolt in which a flange portion which is a joint piece portion formed at an end portion of a pipe which is a joint member or the like, and a flange portion which is a joint piece portion of a valve are arranged on a concentric circle, and Since it is fixed by a plurality of fixing members such as nuts, and the fixing portion is further tightened on the inner peripheral side of the fixing member by a reinforcing jig, it is a joint piece even when a large load due to an earthquake or the like acts on the joint The possibility of deformation or breakage of the flange portion can be reduced.
しかしながら、特許文献１に係る接合部固定構造においては、固定部材であるボルト及びナットの締結力で接合片部であるフランジ部を固定しているから、地震等が発生し、ボルト部分に、ボルトに直交する方向のせん断応力が働き、ボルトが破断した場合には、上記ボルト及びナットの締結力が解除され、その結果、接合片部であるフランジ部が移動し、管の変形又は破断が生じるという不具合がある。 However, in the joint fixing structure according to Patent Document 1, since the flange portion that is the joint piece portion is fixed by the fastening force of the bolt and nut that is the fixing member, an earthquake or the like occurs, and the bolt portion When the bolt is broken due to the shear stress in the direction orthogonal to the bolt, the fastening force of the bolt and nut is released, and as a result, the flange portion, which is the joining piece, moves and the tube is deformed or broken. There is a problem that.
また、特許文献１に係る接合部固定構造においては、フランジ部等の接合片部に複数の補強治具を打ち込むものであり、複数の補強治具を打ち込む作業は施工作業上煩雑であると共に、施工コストを増大させるという不具合がある。
本発明はこのような従来からの不具合を解決するためのものであって、その課題は、施工作業を容易にすると共に施工コストを低減しつつ、地震等による固定部材に直交する方向のせん断応力による固定部材の破断可能性を低減させることで、接合片部の移動を防止し、管の変形又は破断可能性を低減させることを可能とある接合部構造を提供することにある。 The present invention is for solving such a conventional defect, and the problem is that the shear stress in the direction perpendicular to the fixed member due to an earthquake or the like is reduced while making the construction work easy and reducing the construction cost. It is an object of the present invention to provide a joint structure capable of preventing the movement of the joining piece portion and reducing the possibility of deformation or breakage of the tube by reducing the possibility of the breaking of the fixing member.
