ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an expandable, rile accommodation structure.
An accomodation of this kind is known from the patent SE 9603266-9 and has proved operable in the intended way up to a specific size. One of its advantages is that it can maintain a decided width determined with a knowledge of the regulations in different countries. The maximum height is decided by the free height of viaducts to pass under. If the size of the roof sections exceeds the width of the central structure it is necessary to pile up a plurality of roof sections on the central structure, and in this case the total height easily becomes too large, which limits the size of the accomodation.
OBJECT OF THE INVENTION
The object of the invention is to provide a solution of this problem that permits the arrangement of essentially larger units in a simple way without increase of the height of transportation.
This object has been achieved in accordance with the invention in that the accomodation comprises a central structure having a roof that is arranged to be vertically adjustable so as permit foldable roof sections, in the folded state, to be kept folded like an accordion and laying with one side surface supported by the roof of the central structure when the roof is in a lowered position. The outermost roof sections are constantly joined, one of them with the roof edge of the central structure and the other with the top edge of the completely retracted, longitudinal side wall. At enlarging, the package of roof sections is pivoted around the two hinged edges during raising of the roof of the central structure and moving of the longitudinal side wall outwards until the bottom hinges of the roof sections are positioned in a horizontal level and can slide into corresponding guide rails when the roof sections are pulled apart from each other. The dimensions may be such that a plane roof is obtained, but preferably the roof sections are arranged such, that a roof having a number of identical ridges is obtained, which has a larger ceiling height and a larger mechanical strength with respect to snow load, for instance. The ceiling height is limited by the height of the walls, which, in turn, is limited by the permitted maximum height of transportation. This is a disadvantage, because there is a need of ceiling heights of up to 4-5 meters.
This problem has been solved by providing the side walls with longitudinal, hinged sections and the roof of the central structure with an extended movability in, the vertical direction, so that an essential increase of the ceiling height has been obtained in a simple way. The movability of said roof is suitably achieved by four hydraulic cylinders acting upon the roof.
