[0022] The present invention will be further explained below in conjunction with the drawings.
[0023] The invention provides a welded structure for openings of the bulkhead panels of a ship and its matching patch panels, including the through-hole hole pattern of the ship's reinforcement and its matching patch panel structure. Such as figure 2 , image 3 As shown, the through hole includes a first arc, the first arc is connected to the first elliptic arc, the first elliptic arc is connected to the second arc, and the upper end of the second arc is connected to the upper half waist circle, and the lower left of the upper half waist circle Connect the ends to a straight line. Such as Figure 4 , Figure 5 As shown, the patch plate includes a third arc, the lower end of the third arc is connected to the second elliptical arc, the second elliptic arc is connected to the fourth arc, and the other end of the fourth arc is connected to the fifth arc. The five arcs are connected to ...
