Description

Technical Field

[0001] This invention relates to the field of marine technology, and in particular to an integrated double-bottom lashing and fixing structure for multipurpose vessels. Background Technology

[0002] Multipurpose vessels offer great flexibility in cargo loading, capable of transporting bulk cargo, steel coils, and containers. Since containers need to be loaded in the cargo holds, lashing devices are installed on the double bottom to secure the containers within the holds.

[0003] Due to the requirements for loading and packaging cargo, the inner surface of the cargo hold on multipurpose vessels must remain smooth and free of any protruding structures. Therefore, the lashing fasteners of the double bottom feature two downward-recessed bowl-shaped structures. To support the lashing fasteners, longitudinal stiffeners or longitudinal reinforcement structures are required between the two bowl-shaped structures. The gap d between the two bowl-shaped structures of the lashing fasteners is a fixed value, typically around 58mm. The longitudinal stiffeners or longitudinal reinforcement structures are limited by the distance d, and their structural dimensions cannot be too large; otherwise, welding will be impossible, and the fasteners will be damaged due to insufficient reinforcement.

[0004] The dimensions of longitudinal stiffeners or longitudinal reinforcing structures need to be determined based on the stress on the container and the deformation of the hull structure. In some areas, the thickness exceeds 40mm, making welding difficult and the welding quality cannot be effectively guaranteed, resulting in insufficient structural strength of the lashing fasteners and damage. Summary of the Invention

[0005] In order to overcome the above-mentioned defects in the existing technology, the present invention provides an integrated double-bottom binding and fixing structure for multipurpose vessels.

[0006] The present invention solves the above-mentioned technical problems through the following technical solution: An integrated double-bottom lashing and fixing structure for a multi-purpose vessel is provided on the double bottom of the vessel. It includes a shell fixed to the double bottom, the top of which is not higher than the double bottom. The shell extends laterally along the vessel, and its projection in the lateral direction is semi-circular. End plates are provided at both ends of the shell. The top of the end plates is not higher than the double bottom. The top of the shell and the top of the end plates form a rectangle. A supporting structure is provided inside the shell. The supporting structure is semi-circular. A longitudinal reinforcement is fixed at the bottom of the shell, and the center line of the supporting structure is aligned with the center line of the longitudinal reinforcement.

[0007] Furthermore, the supporting structural components are located in the middle of the shell.

[0008] Furthermore, the top of the supporting structural member is not higher than the double bottom.

[0009] Furthermore, the supporting structural components are plate-shaped.

[0010] Furthermore, the thickness of the supporting structural components shall not be less than 20mm.

[0011] Furthermore, the thickness of the longitudinal reinforcement at the connection with the shell is not less than the thickness of the supporting structure.

[0012] Furthermore, the longitudinal reinforcement is a longitudinal skeleton or a longitudinal strong structure.

[0013] Furthermore, the sealing plate is a semi-circular flat plate.

[0014] Furthermore, the shell is semi-cylindrical.

[0015] Furthermore, the sealing plate is a curved panel, which is semi-circular in the transverse projection of the ship.

[0016] The beneficial effects of this invention are as follows: Compared with the prior art, this invention integrates two independent lashing bowl structures into a single integrated shell structure, solving the problem of construction limitations due to excessively large longitudinal reinforcements. This improves the structural strength of the lashing fasteners and reinforcements, making construction and operation more convenient and allowing for flexible adjustments based on container layout. In this invention, the longitudinal stiffeners or longitudinal reinforcing structures can be effectively fixed to the shell, ensuring the structural strength of the lashing fasteners. This invention's integrated double-bottom lashing fastener for multipurpose vessels, while meeting structural strength requirements, also offers ease of construction and operability, improving the structural safety of the lashing fasteners.

[0022] The present invention will be described more clearly and completely below with reference to a preferred embodiment and the accompanying drawings.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an integrated double bottom lashing and fixing structure for a multipurpose vessel is provided on the double bottom 10 of the multipurpose vessel; it includes a shell 11 fixed to the double bottom 10, the top of the shell 11 is not higher than the double bottom 10; the shell 11 extends laterally along the vessel, and the projection of the shell 11 in the lateral direction of the vessel is semi-circular.

[0024] In the field of shipbuilding, the length direction is described as the longitudinal direction of the ship, and the beam direction is described as the transverse direction of the ship.

[0025] The shell 11 has end plates 12 at both ends; the top of the end plates 12 is not higher than the double bottom. The top of the shell 11 and the top of the end plates form a rectangle.

[0026] The housing 11 is provided with a support structure 13; the support structure 13 is semi-circular.

[0027] The supporting structure 13 is located in the middle of the shell. The top of the supporting structure 13 is not higher than the double bottom. The supporting structure 13 is plate-shaped. The thickness of the supporting structure 13 is not less than 20 mm.

[0028] A longitudinal stiffener 14 is fixed to the bottom of the shell 11, and the centerline of the supporting structure 13 is aligned with the centerline of the longitudinal stiffener 14. The longitudinal stiffener 14 is a longitudinal skeleton or a longitudinal reinforcement structure.

[0029] The thickness of the longitudinal stiffener 14 at the connection with the shell is not less than the thickness of the supporting structure 13.

[0030] The sealing plate 12 is a semi-circular flat plate; the shell is semi-cylindrical.

[0031] In another implementation, such as Figure 5 As shown, the sealing plate 12 is a curved panel, which is semi-circular in the transverse projection of the ship.

[0032] Compared with the prior art, the present invention integrates two independent binding bowl structures into a single shell structure, which solves the problem of construction being impossible due to the excessive size of the longitudinal reinforcement, improves the structural strength of the binding fasteners and reinforcement structure, makes construction and operation more convenient, and can be flexibly adjusted according to the container layout.

[0033] In this invention, the longitudinal stiffener or longitudinal reinforcing structure, which serves as a longitudinal reinforcement, can be effectively fixedly connected to the shell, ensuring the structural strength of the binding and fixing structure.
