Abstract

The invention provides a longitudinal grillage structure applied to a large container ship. A lower edge of a longitudinal member web plate is welded with a sheer strake of a ship body, and the longitudinal member web plate and the sheer strake are located on the same one plane; the edge at one side of the longitudinal member web plate is in deep penetration welding with the upper edge of the longitudinal member web plate, and a longitudinal continuous top plate is perpendicular to the longitudinal member web plate; the upper edge of a top plate reinforcing rib is welded to the edge at one side of the longitudinal continuous top plate back to the longitudinal continuous web plate, and the top plate reinforcing rib is in parallel to the longitudinal continuous web plate; the edge of one side of the web plate reinforcing rib is welded with one face of the longitudinal continuous web plate facing to the ship body, and the web plate reinforcing rib is arranged at half in height of the longitudinal continuous web plate; the upper end of every rib plate is in rounding connection with the top plate reinforcing rib, and the lower end of the rib plate is connected with an upper deck. The longitudinal grillage structure can effectively improve the total longitudinal strength of the large container ship; especially, the rigidity of the ship beam can be increased by about 10%.

Description

technical field [0001] The invention relates to the technical field of large container ships, in particular to the technical field of a longitudinal plate frame structure applied to large container ships. Background technique [0002] Due to the continuous pursuit of ship owners for the economies of scale of ships, the ordering of ultra-large container ships has continued to flourish in recent years. International liner companies have accelerated alliances and increased their efforts to order ultra-large container ships. The container space has exceeded 20000TEU. [0003] Generally, the width of the opening of the cargo hold of a large container ship has reached or even exceeded 85% of the ship's width, and the length has reached 90% of the bulkhead spacing. For the 20000TEU ultra-large container, the transverse opening scale has reached 90.37%, the rigidity of the superstructure is very weak, and the problem of the longitudinal strength of the hull girder is particularly p...
