Elastic connecting structure for small waterplane area catamaran

The elastic connecting structure comprises a connecting assembly, a cover plate assembly and padding, the two sides of the connecting assembly are connected with a ship deck respectively, an opening is formed in one end of the connecting assembly, and a plug welding hole is formed in the other end of the connecting assembly; the cover plate assembly is arranged on the opening and the plug welding hole; the space defined by the connecting assembly and the cover plate assembly is filled with the filler. According to the connecting structure, the transverse rigidity of the deck house and the main hull structure can be weakened, the degree that the deck house structure participates in the total transverse bending of the hull is further reduced, and the lightweight design of the ship structure is achieved. 本实用新型提供了一种用于小水线面双体船的弹性连接结构，包括连接组件、盖板组件以及填料，所述连接组件两侧分别与船舶甲板连接，所述连接组件一端设置有开口，另一端设置有塞焊孔；所述盖板组件设置在所述开口和所述塞焊孔上；所述填料填充在所述连接组件与所述盖板组件围合而成的空间内。在本实用新型中，通过设置上述连接结构，能够削弱甲板室与主船体结构的横向刚度，进而降低甲板室结构参与船体总横弯曲的程度，达到船舶结构的轻量化设计。
