The invention discloses a marine steel gate body which comprises outer wall plates, inner wall plates, horizontal longitudinal ribs, vertical T-shaped profiles, horizontal T-shaped profiles, a top platform and a bottom platform, the outer wall plates and the inner wall plates are arranged at intervals, and the outer wall plates and the inner wall plates are connected through the horizontal longitudinal ribs. The near top end and the bottom end of the outer wall plate extend towards the side close to the inner wall plate to form a top platform and a bottom platform, a cavity between the outer wall plate and the inner wall plate is sealed through the top platform and the bottom platform, and a plurality of vertical T-shaped profiles and a horizontal T-shaped profile are arranged between the top platform and the bottom platform. And wing plates of the vertical T-shaped section bar and the horizontal T-shaped section bar are fixedly connected with the outer wall plate and the inner wall plate. According to the steel gate body for the ship, the gate body has good strength and rigidity, the impact load possibly encountered by the ship in the sailing process and the inertial load effect caused by the sailing posture change of the ship can be borne, and meanwhile the interior of the ship is isolated from the external complex marine environment.

本发明公开了一种船用钢质大门本体，包括外壁板、内壁板、水平纵骨、垂向T型材、水平向T型材、顶部平台和底部平台，外壁板和内壁板间隔设置，外壁板和内壁板之间通过多根水平纵骨连接，外壁板的近顶端和底端分别向靠近内壁板一侧延伸有顶部平台和底部平台，顶部平台和底部平台将外壁板和内壁板之间的腔体封闭，顶部平台和底部平台之间设置有多根垂向T型材和一根水平向T型材，垂向T型材和水平向T型材的翼板均与外壁板及内壁板固定连接。本船用钢质大门本体，其大门本体具有良好的强度、刚度，能够承受船舶在航行中可能遭遇的冲击载荷以及由于船舶航行姿态变化引起的惯性载荷作用，同时实现船内与外界复杂海洋环境相隔离。
