The invention provides an upper frame (23) for a construction machine which has a side deck (B') on which a cabin (4) is loaded, and allows the side deck to be effectively reinforced. The side deck includes a front beam (11), a rear beam (10), a left vertical beam (12), a right vertical beam (13), left and right mount holding members (16,17) disposed on inner sides of left corner portion formed by the front beam and the left vertical beam and the right corner portion formed by the front beam and the right vertical beam respectively to hold cabin mounts, and a reinforcement member (25) extending longitudinally of the side deck to be joined to an inner lateral surface of a beam to be reinforced, the beam to be reinforced selected from the left and right vertical beams. The mount holding member (24) of the left and right mount holding members to be attached to the beam to be reinforced is a cross allowing member which has a shape avoiding the reinforcement member so as to allow the reinforcement member to extend across the mount holding member longitudinally of the side deck. A front end of the reinforcement member is directly joined to the front beam while the reinforcement member extends longitudinally across the cross allowing member. |
