Variable cross-section corrugated bulkhead assembly and ship including same

Abstract

The invention discloses a variable cross-section corrugated bulkhead assembly and a ship including same. The variable cross-section corrugated bulkhead assembly comprises a first corrugated bulkhead which is vertically arranged between a main deck of a ship and the internal bottom plate of a cabin, wherein the cross section of the first corrugated bulkhead in the vertical direction is invariable;and the two ends of the first corrugated bulkhead in the vertical direction are correspondingly connected with the main deck and the internal bottom plate through a second corrugated bulkhead, whereinthe cross section of the second corrugated bulkhead in the vertical direction is gradually increased from one end close to the first corrugated bulkhead to one end far away from the first corrugatedbulkhead. Through adoption of the variable cross-section second corrugated bulkhead, the supporting strength of the whole variable cross-section corrugated bulkhead assembly can be met by using the variable cross-section structure, and the variable cross-section corrugated bulkhead assembly directly replaces a structure with an upper wall pier and a lower wall pier; and therefore, the manufacturing steps are simplified, the manufacturing difficulty is reduced, the large-area stress concentration situation is avoided, and the potential safety hazard is reduced; and moreover, an independent cabin structure does not need to be divided for the second corrugated bulkhead, the volume of the cabin is made large, and the loading capacity is greatly enhanced.

Description

Technical field [0001] The present invention relates to the technical field of ships, in particular to a variable cross-section trough wall assembly and a ship containing the same. Background technique [0002] Existing tankers generally use vertical trough-shaped walls with upper and lower piers. The upper end of the trough-shaped wall is connected to the deck through the upper-wall pier, and the lower end of the trough-shaped wall passes through the lower pier. The wall pier is connected with the inner bottom of the cargo tank of the tanker. The trough wall in the cargo hold is mainly used as the watertight (or oiltight) partition wall of the cargo hold. [0003] The existing vertical trough-shaped walls have the following defects: 1. Because the upper and lower piers mainly increase the supporting strength of the trough-shaped walls, the structural size is relatively large, and there are usually independent cabins in them. A set of independent ventilation, ventilation and main...

Problems solved by technology

[0003] The existing vertical grooved walls have the following defects: 1. Since the upper wall piers and the lower wall piers are mainly to increase the supporting strength of the grooved walls, the structural size is relatively large, and there are usually independent cabins in them, which generally require a A set of independent ventilation, ventilation and maintenance equipment increases the equipment cost of the ship; 2. The structure of the upper wall pier and the lower wall pier is complex, the weight of the steel is large, and the cost is high, and the cabin inside the lower wall pier is usually used as a ballast water tank. The internal structure is complex, requiring welding, grinding, painting, etc., and the manufacturing and construction costs are very high; 3. There is generally a large stress concentration at the connection between the upper wall pier, the lower wall pier and the groove wall, resulting in the The structure at the intersection of the molded walls is damaged, and there is a big safety hazard
