Apparatus for assembling blocks of a hull which comprises as many carriages as there are floor plates to be welded, the carriages being arranged on at least one pair of parallel rails fixedly mounted on a standard bed, each carriage comprising a pair of wheel frames, a horizontal frame, a vertical frame, and a tiltable frame. The horizontal frame is provided with as many longitudinal member sockets and fixing devices as there are lower longitudinal members to be welded, and first and second floor plate sockets and a floor plate fixing device. The vertical frame is provided with a pivotable jig on its upper portion. The tiltable frame is pivotable about the upper end of the vertical frame and is provided with as many longitudinal member socket and fixing devices as there are upper longitudinal members to be welded. When respective cylinders for the first and second floor plate sockets, the pivotable jigs, the floor plate fixing devices and the longitudinal member socket and fixing devices are actuated, a girder, the floor plates and the upper and lower longitudinal members are located in proper alignment and position, and they are then directly subjected to the process of regular welding. |
