摘要

A set of members (15a) forming an upper frame (15) of a construction machine 10) includes a center section (20), a left side deck (30L), and a right side deck (30R). The left side deck (30L) has a left deck beam (32). The right side deck (30R) has a right deck beam (32R). At least one of the left deck beam (32L) or the right deck beam (32R) is adjustment deck beams. The adjustment deck beam (32R, 32L) has a contacting part(32c) that is adapted to be brought into contact with and is also adapted to be welded to an external side surface (22a) of an adjustment-side longitudinal plate (22L), a first opposing part (32b) that is adapted to be opposed to a side surface (21b) of the bottom plate (21) and is also adapted to be welded to the side surface (21b), and a second opposing part (32a) that is adapted to be opposed to an upper surface (21a) of the bottom plate with a height-adjustment gap therebetween.
