Abstract
In a structure where a floor plate (10) is mounted above a bottom plate (9) of an upper frame while being supported by a plurality of pillars, a left-rear pillar (16) required to be demounted and re-mounted, among the plurality of pillars, is provided with a spacer (35) adapted to increase a height dimension of the pillar (16), and a combination of a screw hole and a bolt (39) which serve as screw unit adapted to support a load to be applied to the spacer (35), in place of the spacer (35). Under a condition that the load is supported by the screw unit, the spacer (35) is detached to reduce the height dimension of the pillar (16). Then, under a condition that the load is supported by the remaining pillars, the left-rear pillar (16) is demounted.
