The invention discloses a deck grillage structure suitable for oil tankers and bulk cargo ships, which comprises a main deck, longitudinal ribs and strong cross beams are arranged below the main deck, the longitudinal ribs and the strong cross beams are distributed in a transverse and longitudinal array mode, the longitudinal ribs continuously penetrate through the strong cross beams, the deck grillage structure is characterized in that the strong cross beams comprise webs and panels, the webs are perpendicular to the main deck, the webs are fixedly connected with the main deck, and the panels are fixedly connected with the webs. The panel is perpendicular to the web plate and fixed to the bottom of the web plate, one side of the strong cross beam is connected with an anti-inclination toggle plate, the anti-inclination toggle plate is located between the adjacent longitudinal bones, and the three side edges of the anti-inclination toggle plate are fixedly connected with the main deck, the web plate of the strong cross beam and the panel respectively. Transverse flat steel is arranged between the two deck longitudinal bones in the width direction of the ship, and the toe end of the anti-toppling toggle plate is in a circular arc shape and is welded to the transverse flat steel. Compared with the prior art, the stress concentration phenomenon of the deck longitudinal bone can be relieved, so that the fatigue strength of the longitudinal bone is improved, and the thickness of the main deck is reduced. And a back toggle plate of the anti-tilting toggle plate can be omitted, so that good economical efficiency and practicability are achieved.

    本申请公开了一种适用于油船和散货船的甲板板架结构,包括主甲板,主甲板下设有横纵阵列分布的纵骨和强横梁,所述纵骨保持连续穿过所述强横梁,其特征在于,所述强横梁包括腹板和面板,腹板垂直于主甲板、腹板与主甲板固定连接,面板垂直于腹板、面板固定于腹板底部,所述强横梁一侧连接有防倾肘板,所述防倾肘板位于相邻的纵骨之间,防倾肘板的三个侧边分别与主甲板、强横梁的腹板以及面板固定连接。在两根甲板纵骨之间,设置沿船宽方向的横向扁钢,防倾肘板的趾端呈圆弧形并与横向扁钢焊接。与现有技术相比本发明可缓解甲板纵骨的应力集中现象,从而提高纵骨的疲劳强度,减小主甲板的厚度。并可省去防倾肘板的背肘板,故有良好的经济性和实用性。
