Bottom structure of a container ship with concentrated arrangement of bottom girders

Abstract

The invention discloses a bottom structure of a container ship with bottom longitudinal girders arranged in a concentrated manner, comprising an outer bottom plate and an inner bottom plate arranged from bottom to top, a number of containers are arranged on the upper surface of the inner bottom plate, and several containers pass through a plurality of equally spaced holes in the inner bottom plate. The set box feet are fixed on the inner bottom plate, longitudinals are arranged at equal intervals at several box feet on the lower end surface of the inner bottom plate, and several longitudinals corresponding to the upper and lower positions of the longitudinals arranged on the lower end surface of the inner bottom plate are arranged on the outer bottom plate, Several longitudinals are arranged parallel to the ship’s breadth centerline; several heavy bottom longitudinal girders are arranged transversely on the upper end of the outer bottom plate; several light bottom longitudinal girders are arranged in parallel between several heavy bottom longitudinal girders; Several solid ribs. The bottom structure of the container ship provided by the present invention can increase the modulus margin of the bottom and increase the rigidity of the bottom through the spaced longitudinal girders arranged near the midship area and the solid floors arranged near the side area, and has low cost and high strength. high merit.

Description

technical field [0001] The invention relates to the field of ship design and manufacture, in particular to a bottom structure of a container ship with bottom longitudinal girders arranged in a concentrated manner. Background technique [0002] The bottom of the ship can be divided into single bottom and double bottom, and can be divided into transverse frame type and longitudinal frame type according to the frame form. The single-layer bottom structure has only one layer of bottom plate, which is simple in structure and convenient in construction, but has poor sinking resistance. It is mostly used for small ships, small civil ships and the bow and tail of civil ships. In addition to the bottom plate of the double bottom, there is also an inner bottom plate. When the bottom of the ship is damaged due to accidents such as hitting a rock or running aground, the double bottom can ensure the safety of the ship. The space in the double bottom tank can be loaded with fuel oil, lub...
