<p>The subject matter of the invention is that of the construction of extendible structures fabricated in aluminium or steel of double or triple telescopic quadrangular tube, of precisely the same dimensions as those laid down for the construction of cages and maritime containers, with a view to facilitating transportation thereof overland and by sea. The invention lies in the novelty of using telescopic tube in order to make it possible to expand in terms of length, width and height; by removing the securing devices that immobilize the structure - screws, pins and clamps - said structure is extended, one side being anchored down and the opposite side being pulled with a vehicle, and the columns move with the telescopic tubes that connect them in order to close the new part of the expanded structure. The structure is extended upwards by means of a jib crane pulling up on the upper frame that connects the interior telescopic columns, which, upon reaching the planned height, are fastened with umbrella-type spring catches. This invention is of use in the prefabricated construction of dwellings, schools, agricultural buildings, greenhouses, warehouses, offices, gymnasiums, factories, military installations, field hospitals, disaster-relief shelters, etc. The technical solution provided by this invention is that the latter may be adapted to the standard of the future European container, although that was not the intention of this invention, the intended purpose being, rather, that of obtaining a great deal more space - up to eight times the volume of the container selected. The current alternative is to stack eight identical containers on two levels in order to achieve the same result.</p> |
