To provide a frame of a construction machine capable of improving rigidity of a support member.SOLUTION: A frame 2 includes a bottom plate 4, a pair of vertical plates 6 which are arranged on the upper surface of the bottom plate 4 at an interval in a width direction and extend in a longitudinal direction and a vertical direction, and a plurality of support members 8 extending to the outside in a width direction from the outside surface in the width direction of the pair of vertical plates 6. At least one of the plurality of support members 8 includes a vertical wall 20 perpendicular to the bottom plate 4. The inside end in the width direction of the vertical wall 20 is welded to the outside surface in the width direction of one of the pair of vertical plates 6. Lower ends of the pair of vertical plates 6 are intermittently welded to the upper surface of the bottom plate 4, and a non-welding part 34 where the lower end of the vertical plate 6 is not welded to the upper surface of the bottom plate 4 is present in the lower part of the inside end in the width direction of the vertical wall 20.SELECTED DRAWING: Figure 4
【課題】サポート部材の剛性を向上させることができる建設機械のフレームを提供する。【解決手段】フレーム2は、底板4と、幅方向に間隔をおいて底板4の上面に配置され前後方向および上下方向に延びる一対の縦板6と、一対の縦板6の幅方向外側面から幅方向外側に延びる複数のサポート部材8とを備える。複数のサポート部材8の少なくとも1個は底板4に対して垂直な垂直壁20を含む。垂直壁20の幅方向内側端部は一対の縦板6の一方の幅方向外側面に溶接されている。一対の縦板6の下端は底板4の上面に断続的に溶接され、垂直壁20の幅方向内側端部の下方に縦板6の下端が底板4の上面に溶接されていない非溶接部34が存在する。【選択図】図4
