Description

Technical Field

[0001] This utility model relates to the field of ship bulkheads, and in particular to a layered weight-reducing trough-type bulkhead. Background Technology

[0002] Channel bulkheads are ship bulkhead structures formed by pressing steel plates into specific channel-shaped cross-sections, consisting of concave-convex bulkhead plates and a frame. This structure is approximately 20% lighter than flat bulkheads while maintaining the same strength, offering advantages such as steel savings and reduced welding workload. Building on this, further reducing the structural weight while ensuring structural strength is a key research direction for channel bulkheads. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a layered weight-reducing trough-shaped bulkhead, which solves the current pain points in this field.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A layered weight-reducing trough-shaped bulkhead is formed by two layered structural plates joined back to back. The thickness of the layered structural plates is half that of a typical trough-shaped bulkhead. The layered structural plates are divided into short-pitch grooves and long rectangular grooves, which are arranged at intervals with opposite orientations. When the two layered structural plates are joined, the outer ridge of the short-pitch groove of one layered structural plate is joined with the inner groove of the long rectangular groove of the other layered structural plate.

[0006] The short-pitch groove is equidistant from the two sides of the long rectangular groove.

[0007] A reinforcing plate is fixedly installed between the inner corners of the two opposing long rectangular grooves of the two layered structural plates as reinforcement.

[0008] In summary, the advantages of this utility model compared to the prior art are as follows: compared to a general trough-shaped bulkhead, the layered spliced ​​trough plate has the same total thickness of the flat plate on the same cross section, and both have two layers of the layered structural plate. The groove walls of the layered spliced ​​trough plate have the same number of grooves in the same length as a general trough-shaped bulkhead with the same groove width as the short-pitch groove, but the groove walls of the layered structural plate are thinner, thus requiring less material.

[0012] The utility model will be further described in detail below with reference to the accompanying drawings.

[0013] A layered weight-reducing trough-shaped bulkhead is formed by two layered structural plates 1 joined back to back. The thickness of the layered structural plates 1 is half that of a typical trough-shaped bulkhead. The layered structural plates 1 are divided into short-pitch grooves 2 and long rectangular grooves 3, which are arranged alternately with opposite orientations. When the two layered structural plates 1 are joined, the outer ridge of the short-pitch groove 2 of one layered structural plate 1 is joined with the inner groove of the long rectangular groove 3 of the other layered structural plate 1. The short-pitch groove 2 is equidistant from the two side walls 4 of the long rectangular groove 3. The two layered structural plates 1 are fixed together by bolts. A reinforcing plate 5 is fixedly installed between the inner corners of the two opposing long rectangular grooves 3 of the two layered structural plates 1 for reinforcement.

[0014] Compared to a typical trough-shaped bulkhead, the layered trough plate has the same total thickness of flat plates on the same cross section, and both have two layers of the layered structural plate 1. The groove wall 4 of the layered trough plate has the same number of grooves as a typical trough-shaped bulkhead with the same width as the short-pitch groove 2 over the same length, but the groove wall 4 of the layered structural plate 1 is thinner, thus requiring less material.

[0015] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the scope of protection of the present invention. The scope of protection of the present invention is determined by the appended claims.
