Hybrid cargo hold transverse bulkhead structure of LNG (Liquefied Natural Gas) ship

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
