The invention discloses a marine anti-fatigue sectional material through hole structure which comprises a through hole body formed in a mother board, and a sectional material is arranged in the through hole body in a penetrating mode. The stress dispersion hole and the through hole body are integrally formed, the stress dispersion hole is located in the side, close to the top of the sectional material, of the through hole body, the stress dispersion hole comprises a linear part and a buffering arc part, one side of the linear part makes contact with the side wall of the sectional material, and the other side of the linear part makes contact with the side wall of the sectional material. And the other side of the direct part is connected with the top hole edge of the through hole body through the buffer arc part. No high stress concentration point exists, and the risk of fatigue damage of the through hole body is reduced. And the device also has the advantages of reasonable design, simple structure, high efficiency, low cost and the like.

    本发明公开了一种船用防疲劳型材贯穿孔结构,包括:贯穿孔本体,开设在所述母板上,所述贯穿孔本体的内部穿设有型材;应力分散孔,与所述贯穿孔本体一体式成型,所述应力分散孔位于所述贯穿孔本体靠近所述型材顶部的一侧,所述应力分散孔包括直线部和缓冲圆弧部,所述直线部的一侧与所述型材的侧壁相接触,所述直接部的另一侧经所述缓冲圆弧部与所述贯穿孔本体的顶部孔缘相连接。本发明没有高应力集中点,降低了贯穿孔本体疲劳破坏的风险。且其还具有设计合理、结构简单、效率高、成本低等优点。
