BOOM FOOT PART FOR WORK MACHINE
PROBLEM TO BE SOLVED: To mitigate stress at junction between a longitudinal plate and a rear side connection plate (lateral plate) without increasing height of the rear side connection plate while preventing the size of an aperture for fitting a revolving motor, piping, etc. from being decreased.SOLUTION: A longitudinal plate projection 21 extending upward higher than the upper end of a rear side connection plate 16 is provided on a longitudinal plate 12. The upper face of the rear end of a doubling plate 12a and an upper face 16a of the rear side connection plate 16 are butted to each other so that the faces are flush with each other. A weld between the side face of the longitudinal plate 12 and the upper face of the rear end of the doubling plate 12a and a weld between a rear end face 12b of the longitudinal plate 12 and the upper face 16a of the rear side connection plate 16 are connected by a continuous weld 30 without a step.SELECTED DRAWING: Figure 5
【課題】旋回モータ、配管類等を取り付けるための開口部を小さくしないようにしながら後側連結板の高さを上げることなく、縦板と後側連結板（横板）との接合部の応力を緩和する。【解決手段】縦板１２に後側連結板１６の上端よりも上方に延びる縦板突出部２１を設け、ダブリングプレート１２ａの後端部の上面を後側連結板１６の上面１６ａと面一となるように突き合わせ、縦板１２の側面とダブリングプレート１２ａの後端部上面との溶接と、縦板１２の後端面１２ｂと後側連結板１６の上面１６ａとの溶接とを段差なく連続溶接３０で接合する。【選択図】図５
