本発明は例えば鋼構造物における鉄骨柱のダイヤフラムと梁鋼材のフランジとを溶接する際に用いられ、ダイヤフラムと梁鋼材のフランジとの突き合わせ部に生じている食い違いを修正する食い違い修正用治具に関するものである。 The present invention relates to a misalignment correcting jig that is used when, for example, a steel column diaphragm and a beam steel flange in a steel structure are welded, and corrects a misalignment occurring at a butt portion between the diaphragm and the beam steel flange. Is.
従来、この種の食い違い修正用治具として、例えば、突き合わせ状態の一対のＨ形鋼のフランジ間溶接に際し、フランジ突き合わせ部分の相互の芯ずれやウエブ幅方向における各直角度の不具合など、いわゆる食い違いを修正するため、一方のフランジに治具本体を挟着状態に取り付け、この治具本体に他方のフランジを変位させる変位可動部を設けた構造のものが知られている。 Conventionally, as this kind of misalignment correction jig, for example, when welding a pair of butted H-shaped steels between flanges, so-called misalignment such as misalignment of flange butted portions and defects in each perpendicularity in the web width direction, etc. In order to correct this, there is known a structure in which a jig main body is attached to one flange in a sandwiched state, and a displacement movable portion for displacing the other flange is provided on the jig main body.
しかしながら上記従来構造の場合、食い違い修正作業にあっては、食い違い量を目視等により確認しながら変位可動部による移動量を調節する必要があり、それだけ、修正作業が厄介であると共に修正のための作業時間が掛かることがあり、又、変位可動部のフランジの内面を押圧する部位は構造上比較的大きくなり易く、これに対し、鉄骨柱からのダイヤフラムの突出量は例えば２５ｍｍ程度と小さく、しかも、ダイヤフラムの板面には隅肉溶接によるビードも存在していて変位可動部が押圧する部位の接触面積は更に狭くなっており、それだけ、使用し難かったり、使用できないことがあるという不都合を有している。 However, in the case of the conventional structure, in the misalignment correction work, it is necessary to adjust the amount of movement by the displacement movable part while visually confirming the misalignment amount. It may take time to work, and the portion that presses the inner surface of the flange of the movable displacement part is relatively large in structure. On the other hand, the projection of the diaphragm from the steel column is as small as about 25 mm, for example. In addition, there is a bead due to fillet welding on the plate surface of the diaphragm, and the contact area of the part pressed by the movable displacement part is further narrowed, which has the disadvantage that it may be difficult or impossible to use. doing.
本発明はこれらの不都合を解決することを目的とするもので、本発明のうちで、請求項１記載の発明は、鉄骨柱のダイヤフラムと梁鋼材のフランジとの突き合わせ部分に生じているダイヤフラムの板面とフランジの板面との間の食い違いを修正する治具であって、上記フランジに嵌脱自在な治具本体からなり、該治具本体は該フランジの食い違いを修正すべき板面に接触可能な接触部をもつ受け部材及び該フランジの修正すべき板面と背中合わせの反対側の板面を押圧して該フランジの修正すべき板面を該接触部に接触させる押圧ボルトが螺着された保持部材を備えてなり、上記押圧ボルトの先端部に球状運動可能な接面部を設け、上記治具本体に該フランジの修正すべき板面の基準面となる上記ダイヤフラムの板面に当接可能な支点部材を設け、該ダイヤフラムの基準面となる板面に当接する支点部材の当接部位と該フランジの修正すべき板面に接触する接触部との変位を零を含む所定寸法に設定し、上記押圧ボルトは上記フランジの長手方向に並列して二個設けられ、上記支点部材の当接部位は先尖り状に形成され、上記治具本体に略Ｃ形状の補強部材を配設してなることを特徴とする食い違い修正用治具にある。 The present invention aims to solve these disadvantages. Among the present inventions, the invention described in claim 1 relates to a diaphragm formed at a butt portion between a steel column diaphragm and a beam steel flange. A jig for correcting a discrepancy between a plate surface and a plate surface of a flange, the jig main body comprising a jig body that can be fitted to and detached from the flange, the jig main body being a plate surface to be corrected for the discrepancy of the flange A receiving member having a contactable contact portion and a pressure bolt that presses the plate surface opposite to the back surface of the flange to be corrected and makes the plate surface of the flange to be corrected contact the contact portion is screwed. And a contact surface that can be moved in a spherical shape at the tip of the pressing bolt, and the jig body contacts the plate surface of the diaphragm, which serves as a reference surface of the plate surface to be corrected of the flange. Supporting fulcrum member Only, the displacement of the contact portion in contact with the plate surface to be modified abutment portion and the flange abutting the fulcrum member to the plate surface as a reference surface of the diaphragm is set into a predetermined size including zero, the pressing bolt Is provided in parallel with the longitudinal direction of the flange, the contact portion of the fulcrum member is formed in a pointed shape, and a substantially C-shaped reinforcing member is disposed on the jig body. It is in the jig for correcting the discrepancy.
本発明は上述の如く、請求項１記載の発明にあっては、治具本体をフランジに嵌合し、支点部材の当接部位を修正すべきフランジの板面の基準面となるダイヤフラムの板面に当接させると共に押圧ボルトを締付回動すると、受け部材の接触部の辺縁が修正すべきフランジの板面に当接して治具本体は若干斜め状に配置され、この状態で押圧ボルトを締付回動してフランジの修正すべき板面を上記接触部に強制的に接触させ、このとき、支点部材の当接部位と接触部との変位は零を含む所定寸法に設定されているので、変位を零とすれば、フランジの修正すべき板面とダイヤフラムの基準面となる板面とは面一状となり、変位を所定寸法にすれば、ダイヤフラムの板面よりフランジの板面が所定寸法下がった段差状となり、これによりフランジとダイヤフラムとの突き合わせ部分に生じている食い違いを容易に修正することができ、支点部材の存在により接触面積の狭いダイヤフラムと梁鋼材との食い違い修正にも適用することができ、食い違い修正の作業性を向上することができ、かつ、上記押圧ボルトの先端部に球状運動可能な接面部を設けてなるから、フランジの押圧される板面と押圧ボルトのボルト軸線との傾き角度に応じて接面部が球状運動して両者の接触状態を良好に保持することができ、上記押圧ボルトは上記フランジの長手方向に並列して二個設けられているから、フランジの押圧される板面の押圧を良好に行うことができると共に二個の押圧ボルトを交互に締付回動することによりフランジからの治具本体の不測の離脱を防ぐことができ、上記支点部材の当接部位は先尖り状に形成されているから、ダイヤフラムの幅狭い板面と支点部材との当接状態を良好にすることができると共に当接を容易に行うことができて作業性を向上することができ、上記治具本体に略Ｃ形状の補強部材を配設してなるから、治具本体の剛性及び機械的強度を高めることができ、食い違い修正精度を高めることができる。 As described above, according to the first aspect of the present invention, the diaphragm plate is used as the reference surface of the flange plate surface in which the jig body is fitted to the flange and the contact portion of the fulcrum member is to be corrected. When the pressing bolt is tightened and rotated while being brought into contact with the surface, the edge of the contact portion of the receiving member comes into contact with the plate surface of the flange to be corrected, and the jig body is arranged slightly obliquely. By tightening and rotating the bolt, the plate surface to be corrected of the flange is forcibly brought into contact with the contact portion. At this time, the displacement between the contact portion of the fulcrum member and the contact portion is set to a predetermined dimension including zero. Therefore, if the displacement is set to zero, the plate surface to be corrected of the flange and the plate surface serving as the reference surface of the diaphragm are flush with each other, and if the displacement is set to a predetermined dimension, the flange plate from the diaphragm plate surface. The surface becomes a stepped shape with a predetermined dimension down, which The discrepancy occurring at the butt portion of the diaphragm can be easily corrected, and the presence of the fulcrum member can also be applied to correct the discrepancy between the diaphragm and the beam steel with a narrow contact area. Since the contact surface portion that can be improved and is spherically movable is provided at the tip of the pressing bolt, the contact surface portion is provided in accordance with the inclination angle between the plate surface pressed by the flange and the bolt axis of the pressing bolt. It can be held in a spherical motion to maintain a good contact state between them, and since the two pressing bolts are provided in parallel in the longitudinal direction of the flange, the pressing of the plate surface pressed by the flange is excellent. It is possible to prevent unintentional detachment of the jig body from the flange by alternately tightening and rotating the two pressing bolts. Since it is formed in a pointed shape, the contact state between the narrow plate surface of the diaphragm and the fulcrum member can be improved, and the contact can be easily performed to improve workability. Since the substantially C-shaped reinforcing member is disposed on the jig body, the rigidity and mechanical strength of the jig body can be increased, and the misalignment correction accuracy can be increased.
