The invention discloses a transverse strong frame trepanning structure of a bottom side tank of a double-hull ship. The transverse strong frame trepanning structure comprises a transverse non-watertight strong frame arranged on the bottom side tank. The bottom side tank comprises a bottom side tank inclined plate arranged between the broadside inner shell plate and the inner bottom plate; the transverse non-watertight strong frame comprises a strong frame web plate arranged between the bottom side tank inclined plate and the broadside outer plate; a large circular opening is formed in the strong frame web; the left end and the right end of the large hole are located on the left side and the right side of the broadside inner shell plate respectively, and the upper end and the lower end of the large hole are located on the upper side and the lower side of the inner bottom plate respectively. And a ring rib panel is arranged at the edge of the large opening. The stress of the bottom side tank structure is relatively more uniform after the bottom side tank structure is stressed, the stress concentration of the structure is improved, and the structure is safer; the structural weight is lighter, and the construction cost can be reduced.
本发明公开了一种双壳船底边舱横向强框开孔结构,其包括设于底边舱的横向非水密强框;底边舱包括设于舷侧内壳板和内底板之间的底边舱斜板;横向非水密强框包括设于底边舱斜板和舷侧外板之间的强框腹板;强框腹板上开设有圆形的大开孔;大开孔的左端和右端分别位于舷侧内壳板的左侧和右侧,大开孔的上端和下端分别位于内底板的上侧和下侧;大开孔的孔边缘设有圈筋面板。本发明使底边舱结构在受力后应力相对更加均匀,改善结构应力集中,使得结构更安全;使结构重量更轻,还可以降低施工成本。
