A combined grooved bulkhead structure and its manufacturing method

Abstract

The invention discloses a combined trough bulkhead structure and a manufacturing method thereof, which are applied to ships, and include a bent trough bulkhead section and a welded trough bulkhead section, both of which are along the combined trough bulkhead structure The two side sides close to each other in the extension direction of the ship are fixedly connected, the welded corrugated bulkhead section is located in the middle of the combined corrugated bulkhead structure along the ship's width direction, and the vertical panels forming the welded corrugated bulkhead section can be replaced . The combined trough bulkhead structure and its manufacturing method provided by the present invention add a welded trough bulkhead section on the basis of using the press-bent trough bulkhead section, and utilize the panels and cladding of the welded trough bulkhead section. Each plate is a single groove, so that the grooves located on the panel can be replaced, and a structure with higher strength can be used, which changes the structure of the combined bulkhead, especially the parts with higher strength requirements located in the middle along the ship's width direction , not only the production speed is fast, the welding points are few, but also the strength of some areas is guaranteed.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a combined trough bulkhead structure and a manufacturing method thereof. Background technique [0002] The existing vertical trough bulkhead will use the press-bending manufacturing process, because the manufacturing process of the press-bending trough bulkhead is relatively simple. It only needs to use a template to make many identical trough structures connected end to end for welding. And the amount of welding is less, saving time and manpower. However, since some of the panels and webs that form the grooves are the same steel plate, that is, one groove can only use the same plate thickness, there are many restrictions on structural design, and crack defects are also prone to occur during cold-bending manufacturing. Especially for the position near the middle of the ship where the structural stress is relatively high, the buckling strength of the corrugated panel is very high. The...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome the defects in the prior art that the use of the bending groove type bulkhead saves production time and cost, but cannot guarantee the strength of the bulkhead at the position where the buckling strength of the midship is required to be high, and provides a A kind of combined groove type bulkhead structure and manufacturing method thereof
