Problems solved by technology

At present, the channel steel is usually welded on the segment to strengthen its structure, but the channel steel is directly attached and welded to the outer plate and the inner bottom plate of the segment. It is also easy to cause local damage to the segmented structural members

Abstract

The invention discloses a method for segmental strengthening of a weakly rigid double bottom of a ship, comprising the following steps: respectively installing a first reinforcement structure in the bow and stern direction of the segment; installing a second reinforcement structure on the side of the segment, and the second reinforcement The structure is staggered with the longitudinal girders of the first reinforcement structure to form a reinforcement main body; the first reinforcement structure rests on the gantry by inverting the segments. The first reinforcement structure and the second reinforcement structure of the present invention form a "well"-shaped reinforcement body, the reinforcement body is far away from the neutral axis of the deformation of the hull, and can have a significant effect on the reinforcement of the segmented structure.

Description

technical field [0001] The invention relates to the technical field of ship construction, in particular to a method for strengthening the sections of a weakly rigid double bottom of a ship. Background technique [0002] The construction method of modern shipbuilding is divided into sub-units. After the segmented manufacturing is completed and the outfitting is completed, it enters the dock for the production process of combined molding. The whole ship is divided into sections due to the comprehensive consideration of factors such as ship type, structural form, construction efficiency, construction technology, etc., often resulting in some sections with weaker structural rigidity. At present, the channel steel is usually welded on the segment to strengthen its structure, but the channel steel is directly attached and welded on the outer plate and the inner bottom plate of the segment. It is also easy to cause local damage to the segmented structure. SUMMARY OF THE INVENTI...
