Integrated installation method for longitudinal hatch coaming and torsion-resistant box of container

Abstract

The invention discloses a container longitudinal hatch coaming and torsion-resistant box integrated installation method which comprises the following steps that a steel plate is cut to take needed plates, and a hatch coaming assembly is assembled; the precision of the hatch coaming assembly is measured and adjusted; the hatch coaming assembly is welded to a torsion box in the upper jig frame assembling stage, so that hatch coaming and torsion box integrated sections are formed; each precision of the integrated section of the hatch coaming torsion box is measured, analyzed and adjusted; in the segment assembling stage, the precision of a block formed by segment assembling is measured and adjusted, the datum line of each segment in the block is analyzed, and the deviation of the datum line is corrected; the datum line is matched with a dock grid line; and then each precision of the whole cabin is measured and adjusted. According to the invention, the use load of the crane is greatly reduced, and the construction period in the ship dock is shortened; and each precision is measured and is ensured to be within a standard tolerance range, so that the level of ship construction design is improved.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to an integrated installation method of a container longitudinal hatch coaming and a torsion box. Background technique [0002] At present, eight container ships of the 2700TEU Greek series and the 2750TEU Taikoo series have been built in batches in the sea factory area. During the construction of these eight ships, all the longitudinal hatch enclosures are assembled with the torsion boxes in the stage of the general assembly, that is, the longitudinal The sections of the hatch coaming and the torsion box are separately constructed, so each hatch coaming must be hoisted and positioned by a crane during the loading stage, and a single longitudinal hatch coaming starts from hoisting to trimming allowance-assembly-welding , the average construction period in the dock is about 0.5 days. Due to the large number of single-ship hatch enclosure hoisting, the load of the crane is greatl...
