A room unit (1) and a method for the construction and the position mounting of the box-like room unit (1), for instance a cabin, a module assembled from room elements or the like. The room unit intended for an arrangement operable in marine enviroments, for instance for a ship, an offshore construction or the like. The room unit is located on an at least mainly even underlaying (14) of the arrangement, for instance on a ship's deck (14). The method comprises the inclusion of the room unit (1) with a roof (4), walls (2,3) and a floor (12), the lower portion of the wall (2,3) being attached at the outer edge of the self-supporting floor (12). The floor (12) is provided by adjustable damping appliances (21) operable from the interior of the room unit (1). The moving of the room unit (1) is carried out by supporting the unit (1) temporarily at a bag-like air cushion device and at one stabilizing device at least. The room unit ( 1) is after the removal of the temporary support mounted at its position by attaching the damping appliances (21) at said even underlaying (14). The floor (12) of the room unti (1) is adjusted in a desired orientation by trimming the room unit (1) supported by the damping appliance (21) and said floor (12) is adjusted at least mainly out of contact with the underlaying (14) by means of the adjustment of the damping device (21).
A method of providing a floor on a substantially even underlaying, comprising:
A room unit which can be installed on a substantially even underlaying, comprising a self-supporting floor structure having a top, a bottom and a periphery, walls attached to the floor structure about the periphery thereof, and at least one damper appliance which is attached to the floor structure and projects beyond the bottom of the floor structure by an amount which is adjustable from on top of the floor structure, whereby when the room unit is installed on the underlaying, the floor structure can be brought to a position in which it is out of direct mechanical contact with the underlaying over substantially the entire area of the bottom of the floor structure.
A construction having a substantially even underlaying made of metal, a self-supporting floor structure disposed on the underlaying and having a top and a bottom, and at least one damper appliance attached to and effective between the floor structure and the underlaying, the damper appliance maintaining the floor structure in a position in which it is out of direct mechanical contact with the underlaying over substantially the entire area of the bottom of the floor structure, and the damper appliance having adjustment means which are accessible from the top of the floor structure for adjusting the position of the floor structure relative to the underlaying.
