Longitudinal and transverse mixed type framework of cargo ship
Technical Field
The utility model relates to a longitudinal and transverse mixed type framework, in particular to a longitudinal and transverse mixed type framework of a cargo ship.
Background
The hull is a basic part of the ship and can be divided into a main hull part and an upper building part. The main hull part is composed of a plurality of plate frame structures, and can be divided into three forms, namely a transverse framework, a longitudinal framework and a mixed framework (a longitudinal-transverse mixed framework) according to the arrangement direction of the main beam.
When a cargo ship, particularly a bulk cargo ship, is designed into a double-layer shell, a longitudinal and transverse mixed skeleton type ship body structure is generally adopted, a transverse skeleton type skeleton is generally adopted in the middle of a broadside of the cargo ship, a longitudinal skeleton type skeleton is adopted in the upper and lower parts of the broadside of the cargo ship, and the cargo ship is well adapted to the stress characteristics of all parts of the ship body through different skeleton structures. However, the hull structure is complex, the sectional welding difficulty is high, particularly, the transition joint of the longitudinal and transverse frameworks is required to be subjected to proper continuous transition treatment, and the problem of stress concentration is easy to occur at the transition joint of the longitudinal and transverse frameworks. In addition, the transformation of the longitudinal and transverse skeletons cannot structurally make maximum use of the bilge.
