Description
Technical Field
The invention relates to the technical field of ships, in particular to a deck barge cargo blocking coaming structure.
Background
Barge-on-board refers to a barge that is not self-propelled and carries cargo on the deck. As shown in fig. 1, the deck barge is provided with longitudinal retaining coamings 101 and transverse retaining coamings 102 on a deck 100. The cargo has a lateral compression of the cargo fencing, which is its local strength. Conventional fenders are continuous and uninterrupted in the longitudinal direction of the hull, which results in their full participation in the total longitudinal bending deformation of the hull, which is subject to large longitudinal bending stresses (i.e. total strength stresses) when the vessel is underway. For a cargo skirt structure, the structural dimensions required to meet local strength requirements are smaller, while the structural dimensions required to meet overall strength requirements are larger.
Since the longitudinal cargo baffle coamings are connected with the deck of the ship body, the coamings are longitudinally continuous and uninterrupted, which causes the longitudinal cargo baffle coamings to participate in total longitudinal bending deformation along with the ship body beams, and therefore, larger longitudinal bending stress is generated on the longitudinal cargo baffle coamings. In order to make the structural stress value smaller than the allowable value required by the specification, the size of the components of the cargo baffle plate structure needs to be increased. Therefore, the longitudinal cargo baffle boards are large in structural size, the weight of steel materials of the ship body is increased, the ship construction cost is increased, and the cargo carrying capacity of the ship is reduced.
