The invention relates to the technical field of ship body structure design, and discloses a large-span double-deck supporting enclosure bulkhead trepanning type and reinforcing structure which comprises a longitudinal bulkhead, adjacent longitudinal girders, channel trepanning, a double-deck, a transverse supporting enclosure bulkhead, a strong cross beam and a transverse weak plate reinforcement structure. The transverse supporting enclosure bulkhead is arranged between the lower deck and the upper deck, the channel open hole is formed in the transverse supporting enclosure bulkhead, the bottom of the channel open hole is connected with the lower deck, the end of the strong cross beam is provided with an embedded thick plate reinforced structure, and the embedded thick plate reinforced structure is located below the channel open hole. According to the reinforced structure, traditional trepanning bottom reserved roots are removed, the smoothness and applicability of a trepanning channel are improved, the embedded thick plate reinforced structures and the transverse weak plate reinforced structures are arranged on the strong cross beams, local stress concentration is reduced, the structure is simple, the structure is compact, the structure is simple, the structure is compact, the structure is compact, and the structure is suitable for large-scale production and large-scale production of the large-scale production of the large-scale production of the large-scale production of the large-scale production of large-scale production. And the strength of the joint is improved.
本发明涉及船舶船体结构设计技术领域,公开了一种大跨度双层甲板支撑围壁开孔型式及加强结构,包括纵舱壁、相邻纵桁、通道开孔、双层甲板、横向支撑围壁、强横梁和横向弱板加筋结构,所述双层甲板包括上甲板和下甲板,所述横向支撑围壁设在下甲板和上甲板之间,所述通道开孔设在横向支撑围壁上,且所述通道开孔底部与下甲板连接,所述强横梁端部设有嵌厚板加筋结构,所述嵌厚板加筋结构位于通道开孔下方,所述横向弱板加筋结构沿船长方向设置在强横梁两侧且与纵舱壁和相邻纵桁连接,本发明将传统的开孔底部留根去除,提高开孔通道的通畅性和适用性,且在强横梁上设置嵌厚板加筋结构和横向弱板加筋结构减小局部应力集中,增加连接处的强度。
