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.

A counterweight mounting structure for construction machine to which a counterweight is connected through a gap to an exterior constituting an upper rotating body is constituted such that a recessed groove is provided on an end on a connection side of the counterweight, an elastic soundproof material is installed in the recessed groove, and the soundproof material protruding from the recessed groove is brought in contact with, and pressed against an end on the connection side of the exterior when the counterweight is mounted. As a result, there is provided the counterweight mounting structure whose soundproof capability does not decrease even after the counterweight is mounted/dismounted.

In a construction machine having a working attachment, an operator's seat disposed on one side of a machine body, a devices receptacle portion disposed on the other side, and an operating member disposed sideways of the seat for operating the attachment, the machine is characterized in that a canopy comprises a front support post disposed in front of the seat, a rear support post disposed behind the seat, a side support post disposed sideways of the seat and on the side where an operator gets on and off the machine body, and a roof which connects the support posts with one another, the front support post being disposed close to the devices receptacle portion and the side support post being disposed outside the operating member to form an open portion obliquely in front of the seat where open portion is for ensuring a working vision for the attachment which is swung to the seat side.
