The invention discloses a mixed cargo hold transverse bulkhead structure of an LNG (liquefied natural gas) ship. The transverse bulkhead structure comprises a top reinforcing module, a middle reinforcing module, a middle reinforcing module and a bottom reinforcing module, the top reinforcing module comprises a top local longitudinal girder, a top horizontal reinforcing rib and a top inclined supporting plate; the middle reinforcing module comprises a first side longitudinal girder, a second side longitudinal girder and a middle horizontal reinforcing rib; the middle reinforcing module comprises a bottom platform, a middle platform plate, a first local platform, a second local platform, a top platform and middle vertical reinforcing ribs; the bottom reinforcing module comprises a middle longitudinal girder, a bottom local longitudinal girder, a bottom horizontal reinforcing rib and a bottom inclined supporting plate. Through the arrangement of the mixed reinforcing ribs, the buckling strength of the transverse bulkhead is improved, the weight of the reinforcing ribs is prevented from being increased, the structural strength of the transverse bulkhead is improved, the structural weight is reduced, and the construction cost is saved; the side stringers are completely vertically arranged, and the ends of the side stringers are terminated at the horizontal reinforcing ribs, so that the processing and welding workload is reduced, and the construction efficiency is improved.

    本发明公开了一种LNG船混合式货舱横舱壁结构,该横舱壁结构顶部加强模块、中部加强模块、中间加强模块和底部加强模块;所述顶部加强模块包括顶部局部纵桁、顶部水平加强筋、顶部斜撑板;所述中部加强模块包括第一边纵桁、第二边纵桁和中间水平加强筋;所述中间加强模块底部平台、中间平台板、第一局部平台、第二局部平台、顶部平台和中间垂直加强筋;所述底部加强模块包括中纵桁、底部局部纵桁、底部水平加强筋和底部斜撑板。本发明通过混合式加强筋布置,既增加了横舱壁的屈曲强度,也避免了增加加强筋重量,提高了横舱壁结构强度,减少结构重量,节约了建造成本;边纵桁采用完全垂直设置,端部终止在水平加强筋处,减少了加工焊接工作量,提高了建造效率。
