JOINT STRUCTURE AND CONSTRUCTION METHOD OF BEAM END JOINT PORTION
To maximize an effect of preventing breakage of an upper flange when dividing a backing metal at an upper flange side at a beam end joint portion.SOLUTION: In a joint structure of a beam end joint portion in which an H-shaped cross-sectional beam having an upper flange, a lower flange, and a web is joined to a member to be joined: an end of the upper flange in a material axis direction is joined to the member to be joined by a first weld; an end of the lower flange in the material axis direction is joined to the member to be joined by a second weld; a backing metal brough into contact with a bottom of an external beveling formed in the first weld is divided into both sides in a width direction of the web; an end surface at the upper flange side of the web constitutes the beveling bottom in a part where the end at the upper flange side of the web is in contact with the first weld; and a scallop avoiding the second weld is formed at the end at the lower flange side of the web.SELECTED DRAWING: Figure 1
【課題】梁端接合部において上フランジ側の裏当て金を分割する場合に、上フランジの破断を防止する効果を最大化する。【解決手段】上フランジ、下フランジおよびウェブを有するＨ形断面梁を被接合部材に接合する梁端接合部の接合構造であって、上記上フランジの材軸方向の端部は第１の溶接部によって上記被接合部材に接合され、上記下フランジの材軸方向の端部は第２の溶接部によって上記被接合部材に接合され、上記第１の溶接部に形成される外開先の底部に当接される裏当て金は上記ウェブの幅方向両側に分割され、上記ウェブの上記上フランジ側の端部が上記第１の溶接部に接する部分では上記ウェブの上記上フランジ側の端面が上記開先底部を構成し、上記ウェブの上記下フランジ側の端部には上記第２の溶接部を避けるスカラップが形成される、梁端接合部の接合構造が提供される。【選択図】図１
