AI Technical Summary

Technical Problem

The elbow plates at the support bulkheads of existing container ships are prone to cracks when subjected to transverse water pressure, and conventional methods to increase the size of the elbow plate or partially increase the bulkhead will lead to structural heaviness and complex construction.

Description

Technical Field

[0001] The present invention relates to the technical field of ships, and in particular to a diagonal bracing structure for supporting bulkheads of container ships. Background Art

[0002] In order to reduce the direct cross-orthogonal stress concentration, brackets are generally installed at the joints between the platform and the inner shell of the container ship supporting bulkhead. When the ship is subjected to transverse water pressure, the stress level on the bracket is high, and cracks are easily generated at the toe end of the bracket.

[0003] To solve such problems, the conventional approach is to increase the size of the bracket and partially thicken the transverse strength frame. The thickness of the thickened plate often exceeds twice the thickness of the base plate. According to the requirements of the specification, the transition of the plate thickness needs to be considered, which will cause problems such as excessive structural reinforcement and many plate seams that are difficult to construct. For wide-body container ships, these problems are more significant. The method of increasing the bracket is no longer applicable. It is necessary to partially increase the bulkhead and increase the structural strength to reduce the force on the bracket at the connection between the platform and the side to ensure the safety of the structure. However, this method increases the structure and causes an increase in weight. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior art and provide a diagonal bracing structure for supporting bulkheads of a container ship.

[0005] The present invention solves the above technical problems through the following technical solutions:

[0006] A container ship supporting bulkhead diagonal bracing structure is arranged at the connection between the lower end platform and the inner shell in the container ship; it comprises a reinforced bulkhead, and the reinforced bulkhead is fixedly connected to the lower end platform and the inner shell at the same time; the reinforced bulkhead has a diagonal bracing portion and a hollow portion, and the hollow portions are arranged on both sides of the diagonal bracing portion; the upper end of the diagonal bracing portion is fixedly connected to the inner shell, and the lower end of the diagonal bracing portion is fixedly connected to the lower end platform; a plurality of reinforcing frame materials are fixedly arranged on the diagonal bracing portion.

[0007] The reinforced bulkhead is a rectangular plate, and two adjacent end edges of the reinforced bulkhead are respectively fixed to the lower end platform and the inner shell.

[0008] The diagonal braces are distributed along the diagonal direction of the reinforced bulkhead.

[0009] One of the hollow parts is located between the lower end platform, the inner shell and the diagonal support part.

[0010] The reinforcing members are distributed along the length direction of the diagonal bracing part.

[0011] One of the reinforcing frames coincides with the diagonal line of the reinforced bulkhead.

[0012] The reinforcing frames are parallel to each other.

[0013] The number of reinforcing frames is 3.

[0014] A first bracket is provided between the top of the reinforced bulkhead and the inner shell.

[0015] A second bracket is provided between the outer end edge of the reinforced bulkhead and the lower end platform.

[0016] The beneficial effects of the present invention are as follows: the container ship supporting bulkhead diagonal bracing structure of the present invention is provided with a bulkhead with a diagonal bracing structure at the connection between the lower end platform and the inner shell in the container ship, which can not only meet the structural strength safety, but also maximize the use of the structural bearing capacity. The present invention can reduce the weight increased by structural reinforcement, reduce structural plates, and facilitate construction. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is a structural schematic diagram of a preferred embodiment of the present invention. DETAILED DESCRIPTION

[0018] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0019] like Figure 1 As shown, a container ship supporting bulkhead bracing structure is provided at the connection between the lower end platform 10 and the inner shell 20 in the container ship; it includes a reinforced bulkhead 30, and the reinforced bulkhead 30 is fixed to the lower end platform 10 and the inner shell 20 at the same time. In this embodiment, the reinforced bulkhead 30 is a rectangular plate, and two adjacent end edges of the reinforced bulkhead are respectively fixed to the lower end platform and the inner shell.

[0020] The reinforcement bulkhead 30 has a diagonal bracing portion 31 and a hollow portion 32 .

[0021] The upper end of the diagonal bracing portion 31 is fixed to the inner shell 20, and the lower end of the diagonal bracing portion 31 is fixed to the lower end platform 10. The diagonal bracing portions 31 are distributed along the diagonal direction of the reinforced bulkhead.

[0022] Hollow parts 32 are provided on both sides of the diagonal support part 31. One of the hollow parts is located between the lower platform, the inner shell and the diagonal support part.

[0023] A plurality of reinforcing frames 33 are fixedly arranged on the diagonal bracing portion. The reinforcing frames are distributed along the length direction of the diagonal bracing portion. One of the reinforcing frames coincides with the diagonal line of the reinforced bulkhead.

[0024] The reinforcing frames are parallel to each other. In a preferred embodiment, the number of the reinforcing frames is 3.

[0025] A first bracket 41 is provided between the top of the reinforced bulkhead 30 and the inner shell 20. A second bracket 42 is provided between the outer end edge of the reinforced bulkhead 30 and the lower end platform 10. By providing the first bracket and the second bracket, the structural strength is further improved.
