Abstract
Abstract An installation for assemblying ship hull subassemblies each consisting of a pair of vertical subblocks which are assembled in parallel with each other in the longitudinal direction and in transversely spaced apart relation and a horizontal subblock joined to the upper or lower sides of the pair of vertical subblocks. In the parallelepiped structure of the installation, there are provided apparatus for positioning the vertical subblocks, apparatus for holding them in vertical position, and a plurality of carriages with vertically movable scaffolds which are movable on the floor or ride on rails laid within the structure at a predetermined height from the floor.

Claim 1
Independent Claim
220 words
An installation for assemblying ship hull subassemblies each consisting of a pair of vertical subblocks which are to be assembled in parallel with each other in the longitudinal direction and in transversely spaced apart relation and a horizontal subblock to be joined to the upper or lower side edges of said pair of vertical subblocks, said installation comprising a. a parallelepiped structure whose ceiling and at least one side are opened, b. means for separately carrying said subblocks into said structure, c. means for positioning said subblocks in said structure, said positioning means comprising stopper means which is disposed adjacent to one end wall of said structure for abutting against one vertical end of said subblock, and means for pushing said subblock in the longitudinal direction so as to abut said subblock against said stopper means, d. means for releasably engaging with the vertical ends of said vertical subblocks, thereby holding said vertical subblock in vertical position, e. scaffold carriage means which is provided with a plurality of vertically movable scaffolds and which is adapted to travel in the horizontal direction in a lower or upper portion, and f. a carriage adapted to travel upon the floor of said structure, to carry an assembled subassembly thereupon and to move said subassembly out of said structure through said opened side thereof.
Claim 2
Dependent Claim
220 words
An installation for assemblying ship hull subassemblies each consisting of a pair of vertical subblocks which are to be assembled in parallel with each other in the longitudinal direction and in transversely spaced apart relation and a horizontal subblock to be joined to the upper or lower side edges of said pair of vertical subblocks, said installation comprising a. a parallelepiped structure whose ceiling and at least one side are opened, b. means for separately carrying said subblocks into said structure, c. means for positioning said subblocks in said structure, said positioning means comprising stopper means which is disposed adjacent to one end wall of said structure for abutting against one vertical end of said subblock, and means for pushing said subblock in the longitudinal direction so as to abut said subblock against said stopper means, d. means for releasably engaging with the vertical ends of said vertical subblocks, thereby holding said vertical subblock in vertical position, e. scaffold carriage means which is provided with a plurality of vertically movable scaffolds and which is adapted to travel in the horizontal direction in a lower or upper portion, and f. a carriage adapted to travel upon the floor of said structure, to carry an assembled subassembly thereupon and to move said subassembly out of said structure through said opened side thereof.
Claim 3
Dependent Claim
42 words
An installation as defined in claim 1 wherein the spacing between said two positioning means in the transverse direction is adjustable, and said four holding means are so arranged that the spacings therebetween in both longitudinal and transverse directions may be adjusted.
Claim 4
Dependent Claim
17 words
An installation wherein two installations as defined in claim 1 are constructed symmetrically in the longitudinal direction.
Claim 5
Dependent Claim
182 words
An installation as defined in claim 2 further comprising a. a pair of pallets each provided with a longitudinal groove into which is slidably fitted the lower side of said vertical subblock, b. a pair of horizontal bases disposed upon the floor of said structure for supporting said pair of pallets horizontally at the same level and in parallel in the longitudinal direction, one of said horizontal bases being adapted to adjust the transverse position of one of said pallets, c. two stopper means each disposed at one end of each of said pallet so as to receive one vertical end of each of said vertical subblocks, d. two hydraulic cylinder means each disposed at the other end of each of said pallets so as to push each of said vertical subblocks toward said stopper means, e. a pair of parallel rails extended upon the floor of said structure in the longitudinal direction between said pair of horizontal bases, and f. a plurality of carriages each riding upon said pair of rails and having a plurality of vertically movable Scaffolds mounted thereupon.
Claim 6
Dependent Claim
208 words
An installation as defined in claim 2 further comprising a. a first horizontal base disposed upon the floor of said structure along one end wall thereof, b. a second horizontal base movable in the longitudinal direction upon the floor of said structure in parallel with said first horizontal base so that the spacing therebetween may be adjusted, c. means for moving said second horizontal base toward or away from said first horizontal base, d. a plurality of supporting roller means disposed upon the top of said first horizontal base, e. stopper means disposed adjacent to said one end wall for receiving the vertical subblocks, f. hydraulic cylinders mounted upon said second horizontal base for pushing the vertical ends of said vertical subblocks remote from said one end wall, thereby abutting said vertical subblocks against said stopper means, g. a pair of parallel rails laid in the transverse direction within said structure at a predetermined height from the floor along said one end wall and an end wall in opposed relation with said one end wall, respectively, and h. two scaffold assemblies which ride on said pair of parallel rails for movement in the transverse direction and each of which has a plurality of vertically movable scaffolds suspended therefrom.
