Deck barge cargo-blocking coaming structure

Abstract

The invention discloses a deck barge cargo-blocking coaming structure. The deck barge cargo-blocking coaming structure comprises a longitudinal cargo-blocking coaming, the longitudinal cargo-blockingcoaming comprises a plurality of longitudinal coaming sections, and the adjacent longitudinal coaming sections are not directly connected; the longitudinal coaming sections are discontinuously distributed on a ship deck; a coaming connector part is arranged between every two adjacent longitudinal coaming sections; the end part of each longitudinal coaming section comprises a vertical end and an inclined end; each coaming connector part comprises a connector part body, the end portions of the connector part bodies are matched with the end portions of the longitudinal coaming sections, a hollowed-out part is arranged between the end portion of each longitudinal coaming section and the end portion of the corresponding connector part body, and a butt strap is fixedly arranged on each connectorpart body; and the butt straps extend to the longitudinal coaming sections. The longitudinal cargo blocking coaming does not participate in total longitudinal bending deformation of the ship body, sothat the total strength requirement of the longitudinal cargo-blocking coaming does not need to be considered, the component size of the longitudinal cargo-blocking coaming can be reduced, and the aims of reducing the weight of the ship body structure and saving the construction cost are achieved.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a deck barge cargo coaming structure. Background technique [0002] Deck barges are non-self-propelled barges that carry cargo on deck. Such as figure 1 As shown, the deck barge is arranged with longitudinal cargo coamings 101 and transverse cargo coamings 102 on the deck 100 . The cargo has lateral extrusion on the cargo wall, which is its local strength. The conventional cargo coaming is continuous and uninterrupted in the longitudinal direction of the hull, which will cause it to fully participate in the overall longitudinal bending deformation of the hull, and will bear large longitudinal bending stress (ie, the total strength stress) when the ship is sailing. For the cargo coaming structure, the structural size required to meet the local strength requirements is small, while the structural size required to meet the overall strength requirements is large. [0003] Since the...

Problems solved by technology

This makes the structural size of the longitudinal cargo coaming often larger, thereby increasing the weight of the steel material of the hull itself, increasing the cost of ship construction, and reducing the cargo capacity of the ship
