PIPE SUPPORTING DEVICE FOR CONSTRUCTION MACHINE
A pipe supporting device is provided which allows a finishing treatment to be easily performed on a terminating end of grinding performed on a weld formed on an attachment. A pipe supporting device 12 includes a support portion 15 for supporting a hydraulic pipe 11 along an axis D2 of the hydraulic pipe 11 extending along a length D1 of a boom 5, and a weld portion 13 joining the support portion 15 and to be connected with an outer surface of the boom 5 by fillet welding. The weld portion 13 has a plurality of peripheral surfaces standing on the outer surface of the boom 5 for the fillet welding, the plurality of peripheral surfaces including: a pair of opposite perpendicular standing surfaces 13a and 13b extending in a direction substantially perpendicularly intersecting a first stress direction D3 along the axis D2 of the hydraulic pipe 11; and a pair of oblique standing surfaces 13c and 13d extending from respective leading ends of the pair of opposite perpendicular standing surfaces 13a and 13b to join each other. Each of the oblique standing surfaces 13c and 13d extends in a direction oblique to the first stress direction D3 and joins the corresponding one of the perpendicular standing surfaces 13a and 13b at an acute angle.
