The invention relates to the technical field of ocean engineering semi-submerged platforms, and discloses a cross brace structure for a high-sea-condition high-navigational-speed semi-submerged platform, which comprises a plurality of vertically arranged stand columns and further comprises a cross brace, the cross brace is a step-shaped shaft of which the diameter is gradually reduced from two ends to the middle, two ends of the cross brace are horizontally connected between the two stand columns, and the cross brace is arranged between the two stand columns. The invention relates to a cross-brace structure, which is characterized in that the cross-brace structure comprises a stand column, a cross-brace is arranged on the stand column, a connecting toggle plate is arranged at the connecting position of the cross-brace and the stand column, a cross-shaped partition plate is arranged in the cross-brace, and a plurality of reinforcing ring ribs are uniformly arranged on the inner wall of the cross-brace, the rigidity of the cross section of the cross-brace is adjusted through five aspects of the toggle plate at the end of the cross-brace, the cross-brace section form, the cross-shaped partition plate in the cross-brace, the thickness of a cross-brace plate and the partition plate and the reinforcing ribs; the deformation of the cross brace is changed from being concentrated at the end part of the cross brace to being uniformly distributed along the length direction of the whole cross brace, so that the stress concentration phenomenon at the end part of the cross brace under high navigational speed and high sea conditions is reduced, the stress level of each section is uniformly distributed on the premise that the total deformation of a platform is not changed, and the overall strength of the cross brace is enhanced.
本发明涉及海洋工程半潜平台技术领域,公开了一种用于高海况高航速半潜平台的横撑结构,包括多个竖直设置的立柱,还包括横撑,所述横撑为由两端至中部直径递减的阶梯状轴,所述横撑两端水平连接在两根立柱之间,所述横撑与立柱连接处设有连接肘板,所述横撑内部设有十字形隔板,所述横撑内壁上均匀设置多个加强环筋,本发明通过横撑端部肘板、横撑截面形式、横撑内部的十字隔板、横撑板和隔板的板厚、加强筋五个方面调整横撑截面的刚度,使横撑的变形由集中在横撑端部改为沿着整个横撑长度方向均匀分布,减小了高航速高海况时横撑端部的应力集中现象,在平台总变形量不变的前提下,使各段应力水平平均分布,增强了横撑的整体强度。
