The invention discloses a separated ship upper deck bulwark comprising a bulwark plate arranged above an upper deck, a broadside outer plate fixedly arranged on the edge of the upper deck, and a bulwark plate arranged above the broadside outer plate. The bulwark plate is not directly connected with the broadside outer plate; a strip-shaped gap is formed between the bulwark plate and the broadsideouter plate; the strip-shaped gap is a hollow part between the bottom end line of the bulwark plate and the top end line of the broadside outer plate; the strip-shaped gaps extend in the length direction of the ship; the width of the strip-shaped gap is 30-200 mm; the top end line of the broadside outer plate is positioned above the upper deck; a toggle plate is fixedly arranged on the bulwark plate, and the bottom of the toggle plate is fixedly arranged on the upper deck; and the toggle plate is not directly connected with the broadside outer plate. The bulwark plate is separated from the broadside outer plate, the bulwark plate does not participate in total longitudinal deformation of a ship body beam any more, stress caused by total longitudinal deformation of a deck bulwark is obviously reduced, so that the designed plate thickness of the bulwark and the size of reinforcing ribs are effectively reduced, and the structural weight of a ship is reduced.
本发明公开了一种分离式船舶上甲板舷墙,其包括设于上甲板上方的舷墙板;上甲板的边缘固设有舷侧外板;舷墙板设于舷侧外板的上方;舷墙板和舷侧外板之间不直接连接;舷墙板和舷侧外板之间具有条状间隙;条状间隙为舷墙板的底端线和舷侧外板的顶端线之间的镂空部;条状间隙沿船长方向延伸;条状间隙的宽度为30~200毫米;舷侧外板的顶端线位于上甲板的上方;舷墙板固设有肘板,肘板的底部固设于上甲板;肘板与舷侧外板之间不直接连接。本发明使舷墙板与舷侧外板分离,舷墙板自身不再参与船体梁总纵变形,明显降低甲板舷墙总纵变形引发的应力,从而有效减小舷墙设计板厚及加强筋尺寸,减轻船舶结构重量。
