The invention relates to a single-plate and double-plate combined bilge keel, and belongs to the technical field of ship design and manufacturing. The single-plate and double-plate combined bilge keel comprises first plates, second plates and base plates. The ends, close to the hull, of the first plate and the second plate in the width direction are connected with the bilge of the ship through base plates. The first plate and the second plate are different in width size in the width direction of the ship body, the first plate is wider than the second plate, the other end of the second plate in the width direction is arranged in the middle of the first plate in the width direction, and the other end of the first plate in the width direction is a free end. An acute angle is formed between the first plate and the second plate. The total strength of the bilge keel participating in the hull is reduced, the manufacturing process is simplified, and the working efficiency is improved. The risk that the weld seam of the single-plate type bilge keel is torn is reduced, the possible damage type is the type that the middle intersection of the second plate and the first plate is bent, and the damage mode is easy to maintain and short in maintenance period.

    本发明涉及一种单双板组合型式舭龙骨,属于船舶设计制造技术领域。包括板一、板二和垫板;板一和板二沿宽度方向靠近船体的一端通过垫板与船的舭部连接;板一与板二沿船体宽度方向的宽度尺寸不同,板一的宽度大于板二的宽度,板二沿宽度方向的另一端设于板一沿宽度方向的中部,板一沿宽度方向的另一端设为自由端;板一与板二之间形成一锐角。通过本发明减少舭龙骨参与船体的总强度,简化制造工艺,提高工作效率。减少单板型式舭龙骨焊缝撕裂的风险,可能的破坏型式也是板二与板一在中部相交处发生折弯的型式,该破坏模式维修容易,维修工期短。
