By sandwiching the floorboard between the step board part of the frame, the floorboard can be attached to the bottom frame without causing the floorboard to float upward, and it is possible to install the floorboard only from above the bottom frame. Because only the bolts are operated, it is very easy to install the floorboard, and there is no need for nuts, so there is an effect that the installation members can be omitted.

For example, when attaching a floor plate to the lower frame, concentric holes are formed in advance across the stepped plate part of the lower frame, the floor plate, and the holding metal fittings, and nuts are installed on the lower surface side in correspondence with the holes in the stepped plate part. It is conceivable to weld the holes and then screw the bolts into the nuts through the holes, but this would cause damage to the floorboards and make it difficult to align the holes due to manufacturing and assembly errors. In this respect, the present invention makes it easy to align the bolts by simply aligning the bolt insertion holes in the top plate with the screw holes in the holding metal fittings. Since it is clamped between the floor board and the stepped board part, manufacturing errors and assembly errors can be absorbed by the clamping part, and the work of installing the floor board is facilitated in this respect as well.

In addition, in the embodiment, a floor presser is interposed between the floor plate and the presser metal fitting, but this floor presser may be omitted and the presser metal fitting may be configured to directly contact the upper surface of the floor plate. good.
