Abstract A movable building structure surrounds a ship during its construction and is composed of a front frame and a rear frame each including pillar members supporting the building structure which spans across rails, one or more of which are laid on both sides of a building dock building the ship and also to one side of an area accommodating surface plates for assembling parts of the ship structure. The front and rear frames are combined into a boxlike construction and a plurality of overhead traveling cranes are supported inside of the building structure by the frames and pillars. The whole building structure rests on wheels or rollers which rotate on the rails, allowing the building structure to be moved along the rails in accordance with the progress of the shipbuilding works by a hydraulic winch.
A building structure for a ship constructed in a building dock and provided with assembling areas alongside thereof comprising a plurality of pillar support members; a plurality of lateral frames carrying the plurality of pillar support members thereon and spanning across the building dock; a pair of rails laid on both sides of the building dock; means connecting the lateral frames with the rails to permit movement along the rails; longitudinal structural members interconnecting the lateral frames so that a boxlike construction of the building structure is formed which extends partially along the rails; a plurality of overhead traveling cranes supported for lateral movement by the frames and the pillar members, and a pair of conveyors adapted to transport building material into the building structure, said conveyors running parallel to and being disposed between the pairs of rails on each side of the building dock.
