Abstract
A method of assembling a floor structure of a construction machine is based upon the machine with a stepwise part that is located at a lower level on the outside is formed on the end edge of a floor plate as a floor structure. In case of a cabin specification with a cabin mounted, a device for opening and closing a door is housed in the stepwise part with the stepwise part filled in, and a first floor mat having a substantially constant thickness is mounted on the floor plate. In case of a canopy specification having a canopy, a second floor mat having on its end edge a protrusion which is fitted into the stepwise part instead of the device to fill the part is mounted on the floor plate. Accordingly, the same floor plate can be employed in both cabin and canopy specifications, regardless of the specification, thereby reducing the number of parts constituting the floor structure.
