Embodiment Construction

[0036] The present invention will be further described by means of embodiments below in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the following embodiments.

[0037] like Figure 2-3 As shown, the asymmetric watertight corrugated bulkhead 10 includes: a first panel 11 , a second panel 12 , and a web 13 .

[0038] The first panel 11 faces the interior of the cabin, and the second panel 12 faces the outside of the cabin; the width B1 of the first panel 11 is smaller than the width B2 of the second panel 12 , and the width W of the web 13 is equal to the width B2 of the second panel 12 .

[0039] The panel of the watertight grooved bulkhead is set asymmetrically, and on the premise of ensuring its bending capacity, it meets the requirement of yield strength and enhances the buckling resistance, so as to achieve the purpose of reducing the structural weight. The width W of the web 13 is set to be equal to the width B2 of ...

Abstract

The invention discloses an asymmetric watertight corrugated bulkhead and a bulk cargo ship heavy ballast tank. The asymmetric watertight corrugated bulkhead comprises a web, a first faceplate and a second faceplate, wherein the first faceplate faces the interior of a cabin; the second faceplate faces the exterior of the cabin; the width of the first faceplate is less than the width of the second faceplate; and the width of the web is equal to the width of the second faceplate. The bulk cargo ship heavy ballast tank comprises the asymmetric watertight corrugated bulkhead. The faceplates of the watertight corrugated bulkhead are asymmetrically arranged, so that on the premise of ensuring the bending ability of the faceplates, the yield strength requirement is met, and the ability of resistance to buckling is improved, and thus, the purpose of reducing the structural weight is achieved. The weight of the bulk cargo ship heavy ballast tank can be reduced.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to an asymmetrical watertight groove bulkhead and a bulk carrier heavy ballast tank. Background technique [0002] The watertight grooved bulkhead of the heavy ballast tank not only serves as the transverse bulkhead of the ordinary cargo hold to divide the cabin, but also needs to withstand the lateral water pressure under the heavy ballast condition, and the load condition is similar to that of the ordinary cargo hold. The ratio is more complicated, so the watertight corrugated bulkheads of heavy ballast tanks have higher requirements than ordinary watertight bulkheads. At the same time, in the latest common structural code, there is a higher requirement for the buckling capacity of the panel, which leads to very serious buckling results of the panel facing the heavy ballast tank of the watertight corrugated bulkhead under the heavy ballast condition. If the structural form of the conv...
