The invention relates to a hatch coaming structure with total longitudinal strength being taken into account. The hatch coaming structure on a deck is of a continuous pipeline structure. The coaming of the pipeline structure comprises first longitudinal hatch coaming bodies, second longitudinal hatch coaming bodies, hatch coaming top plates and curvature plates, wherein the first longitudinal hatch coaming bodies are located on the left side and the right side of a hatch respectively and close to a ship; the second longitudinal hatch coaming bodies are located on the sides, close to the ship, of the left side and the right side of the ship; the hatch coaming top plates are located on the tops of the first longitudinal hatch coaming bodies and the second longitudinal hatch coaming bodies; the surface plate is connected with the curvature plate; and lightening holes are formed in the first longitudinal hatch coaming and the second longitudinal hatch coaming. The highest point positions of the longitudinal continuous components are not increased, the hatch coaming top plate and the longitudinal continuous components on the left and right sides are additionally arranged to jointly participate in the total longitudinal strength, compared with an existing scheme, construction is simpler and more convenient, the total longitudinal strength and local strength of the structure are further improved, and the ideal weight reduction effect is achieved.

    本发明涉及一种计入总纵强度的舱口围结构,甲板上的舱口围结构呈一连续的管道结构;所述管道结构的围板包括:位于舱口处的左右舷各一道靠船中的第一纵向舱口围板、左右舷各一道靠舷侧的第二纵向舱口围板、位于所述第一纵向舱口围板与第二纵向舱口围板顶部的舱口围顶板、与舱口围顶板平滑过渡相连的曲率板、与曲率板连接的平面板;所述第一纵向舱口围板、第二纵向舱口围板上开设减重孔。本发明不增加纵向连续构件的最高点位置,额外增加了舱口围顶板、左右舷各一道纵向连续构件来共同参与总纵强度,施工上相对现有方案更为简便,并且结构的总纵强度和局部强度都有了进一步的改善,也实现了比较理想的减重效果。
