Ship hatch negative corner packaging structure

Abstract

The invention relates to a ship hatch negative corner packaging structure. The ship hatch negative corner packaging structure comprises a negative corner (1) fixedly arranged at a position of a hatch, wherein the negative corner is used for dividing a liquid tank (2) from a cargo compartment (3); the negative corner is packaged by adopting a bevel (5); the bevel extends from the top of the liquid tank to the lower part of the cargo compartment; an included angle formed between the bevel and a vertical direction is 30 degrees to 60 degrees; and a reinforcing bar (7) is fixedly arranged at a connection position of the liquid tank (2) and the cargo compartment (3), and the trend of the reinforcing bar is parallel to the bevel. According to the ship hatch negative corner packaging structure disclosed by the invention, a design of a bevel structure is adopted, the negative corner is packaged in a beveled packaging form instead of a conventional rectangular sealing form, and the tank capacity loss of the liquid tank is reduced. Stock is not easy to be produced in the bevel structure, and the consumption of plates is less than that of a conventional form, so that the mounting of the reinforcing bar at the back is facilitated, and a triangular beveled bracing form is firmer than a conventional rectangular packaging form in local strength, and is more beautiful.

Description

technical field [0001] The invention relates to a packet structure for a negative corner of a hatchway of a ship, and belongs to the technical field of hatchway corner structure design. Background technique [0002] In the hull structure, the hatch corners are serious high-stress areas because of structural mutations, which will cause stress concentration. In order to alleviate this stress concentration, reduce the stress of the hatch corners, prevent structural cracks, and improve the safety of the hull; at the corners, the deck is usually made into a negative corner. The negative corners ensured the capacity and integrity of the cargo area, but the integrity of the deck strips was compromised. Therefore, it is necessary to additionally set up a packet structure to ensure the structural integrity and tightness of the deck strip (tank). [0003] like Figure 1 to Figure 3 As shown, the traditional packet structure is a rectangular structure, which seals the depression in t...

Problems solved by technology

but by Figure 4 and Figure 5 It can be seen that this kind of packing structure encroaches a lot on the tank capacity, and the cargo tank has a flat bottom, which is easy to cause accumulation of cargo; in addition, the construction process of this structure is complicated, and the installation of the reinforcing ribs on the back is difficult
