Description

Technical Field

[0001] The invention relates to the technical field of ships, and in particular to a bulk carrier hatch deck structure. Background Art

[0002] The hatch deck structure of existing bulk carriers, such as Figure 1 and Figure 2 As shown, it comprises a hatch deck 50, a cantilever beam support bracket 51 and a transverse stiffener 52 are fixedly arranged at the bottom of the hatch deck 50, and the transverse stiffener 52 passes through the cantilever beam support bracket 51 and is connected to the topside tank vertical plate 53. Due to the existence of hard points, in order to avoid stress concentration, transverse stiffener end brackets 54 and transverse stiffener back brackets 55 are respectively fixedly arranged on both side end surfaces of the topside tank vertical plate 53, the transverse stiffener end bracket 54 is arranged below the transverse stiffener 52, and the transverse stiffener back bracket 55 is arranged between the topside tank vertical plate 53 and the topside tank inclined plate 56.

[0003] Disadvantages of the prior art: complex structural strength, waste of materials, increased structural weight and construction process. 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 bulk carrier hatch deck structure.

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

[0006] A bulk carrier hatch deck structure comprises a hatch deck, a topside tank vertical plate is fixedly arranged at the bottom of the hatch deck, a transverse stiffener and a plurality of supporting brackets are also fixedly arranged at the bottom of the hatch deck; a longitudinal bone is arranged between the supporting bracket closest to the topside tank vertical plate and the topside tank vertical plate, the longitudinal bone is fixedly connected to the bottom of the hatch deck, and the end of the transverse stiffener is fixedly connected to the longitudinal bone; no brackets are arranged on the end faces of both sides of the topside tank vertical plate.

[0007] Furthermore, the transverse stiffeners do not extend to the area between the topside tank vertical plating and the longitudinals.

[0008] Furthermore, no transverse stiffener end bracket is provided on the end surface of the topside tank vertical plate facing the centerline.

[0009] Furthermore, no transverse stiffener back bracket is provided on the end surface of the topside tank vertical plate facing outboard.

[0010] Furthermore, the supporting bracket is a cantilever supporting bracket.

[0011] The beneficial effects of the present invention are as follows: in the present invention, the structural strength and deformation requirements can be met by adding a longitudinal bone. The structure of the present invention eliminates hard points and does not have the problem of stress concentration. The present invention can save steel, reduce structural weight, and reduce costs; it can also reduce the number of components, simplify the construction process, and make construction easier.

[0016] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0017] like Figure 3 and Figure 4 As shown, a bulk carrier hatch deck structure comprises a hatch deck 10, a topside tank vertical plate 20 is fixedly arranged at the bottom of the hatch deck 10, a transverse stiffener 11 and a plurality of support brackets 12 are also fixedly arranged at the bottom of the hatch deck 10. The support brackets are cantilever support brackets.

[0018] A longitudinal bone 30 is provided between the supporting bracket 13 closest to the topside tank vertical plate and the topside tank vertical plate 20 , and the longitudinal bone 30 is fixed to the bottom of the hatch deck 10 .

[0019] The ends of the transverse stiffeners 11 are fixed to the longitudinals 30 ; the transverse stiffeners 11 do not extend to the area between the topside tank vertical plating 20 and the longitudinals 30 .

[0020] No brackets are provided on both side end faces of the topside tank vertical plate 20. Specifically, no transverse stiffener end brackets are provided on the end face of the topside tank vertical plate facing the centerline; no transverse stiffener back brackets are provided on the end face of the topside tank vertical plate facing outboard.

[0021] In the present invention, a longitudinal bone is added to the bottom of the hatch deck; the transverse stiffener at the bottom of the hatch deck is connected to the longitudinal bone, and the transverse stiffener is interrupted on the longitudinal bone; the transverse stiffener end bracket and the transverse stiffener back bracket originally arranged on both sides of the vertical plate of the top side tank are cancelled.

[0022] In the present invention, the structural strength and deformation requirements can be met by adding a longitudinal bone.

[0023] The structure of the present invention eliminates hard points and eliminates the problem of stress concentration.

[0024] The present invention can save steel, reduce structural weight and reduce costs.

[0025] The present invention can reduce the number of components, simplify the construction process, and facilitate construction.

[0026] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
