Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ships, in particular to a topside tank transverse frame structure of a bulk carrier. Background Art
[0002] The production of the topside tank transverse frame structure of a bulk carrier has high labor costs due to the processes of rounding and panel bending, or high material costs due to the excessive thickness of the plate. How to reduce the production cost of the topside tank transverse frame structure of a bulk carrier is a problem that needs to be solved.
[0003] Existing bulk carrier topside tank transverse frame structures, such as Figure 1 and Figure 2 As shown in the figure, the topside tank is formed by the hull outer plating 41, deck 42, vertical plates 43, and inclined plates 44. The existing topside tank transverse frame structure of a bulk carrier includes a transverse plate 45 installed within the topside tank. A triangular through-hole 46 is formed within the transverse plate 45. The edge of the through-hole is composed of three straight lines and three circular arcs. The through-hole requires rounding.
[0004] To improve the structural strength, Figure 1 A panel 47 is fixed to the edge of the through hole of the middle transverse plate; Figure 2 A flash 48 is provided on the transverse plate, and the flash is close to the edge of the through hole.
[0005] right Figure 1 For the medium structure, the production of this structure requires rounding and panel bending, which is difficult and labor-intensive. Figure 2 For medium structures, not only does it require chamfering, but because there is a 15mm burr, the plate thickness needs to be significantly increased during local structural strength analysis to meet the specification requirements. The steel material is heavy, the processing is difficult, and the material cost is higher. Utility Model Content
