Abstract

A shrinkable drum device for deck construction, comprising an elongated rotatable shaft; a first series of segments that are arranged in angularly spaced relationship around the axis and each of which has an arcuate outer surface that is arranged concentrically with respect to the geometric axis of rotation of the mechanical axis; a second series of segments that are arranged around said geometric axis, the segments of said second series being interposed respectively between the segments of said first series and each having an arcuate external surface that is arranged concentrically with respect to the geometric axis of the mechanical axis and forming, with said external surfaces of the segments of said first series, a continuous cylindrical surface of construction that is arranged concentrically with respect to said geometric axis, and means to produce the movement of said segments radially with respect to said geometric axis and that they include a pair of links that are associated with each of said segments, one end of each link being rotatably connected to its respective associated segment, a pair of members each of which is movable longitudinally with respect to said geometric axis between said first position and said second position, while the other ends of the links of each one of said pairs thereof are respectively rotatably connected in said pair of members, passing the links, associated with said first series of segments, through the center during movement of said members between said first position and said second position, the links, associated with said second series of segments, being on the center in the first position of said members, and means for simultaneously moving said members longitudinally with respect to said geometric axis.
