Abstract
Description
Technical Field
[0001] This invention relates to the field of ship structural design technology, and in particular to a deck structure for an automobile transport ship and the ship itself. Background Technology
[0002] To ensure the stability of car carriers (PCTC vessels), reduce the ship's weight, and lower the center of gravity, thin plates or high-strength steel plates with a thickness of only 5.5~7mm are extensively used above the main deck. However, thin plates are prone to deformation during processes such as cutting, assembly and welding, placement, transportation, and tilting and hoisting, inevitably leading to a large amount of repair work. This not only increases shipbuilding time and costs but also makes it more difficult to control various precision indicators and quality requirements, resulting in poor structural safety and economy of the ship. Summary of the Invention
[0003] In view of the above-mentioned problems existing in the prior art, the present invention provides a deck structure and vessel for a car carrier to solve the technical problems existing in the prior art, such as the thin plates being prone to deformation during assembly and welding, and the increased difficulty in controlling various precision indicators and quality requirements.
[0004] This invention provides a deck structure for a car carrier: The lower deck area of the cargo hold is constructed using a continuous thin-plate deck. The deck above the cargo hold is constructed with a steel frame and steel plate. Furthermore, the hull structure strength meets the design requirements.
[0005] In one embodiment, the deck in the upper region includes longitudinal beams, transverse beams, and block steel plate units. The longitudinal beams and transverse beams are arranged along the length and width of the ship, respectively. Several longitudinal beams and transverse beams are fixedly intersected to form a cross beam system with a frame structure. The block steel plate units are laid and fixed on the frame structure of the cross beam system. Several block steel plate units are connected to each other to form a closed deck surface.
[0006] In one embodiment, it also includes, Several pillars are arranged at intervals in the cargo hold area along the direction perpendicular to the deck, and the pillars are arranged along the length of the ship.
[0007] In one embodiment, the support is arranged at the intersection of the longitudinal beam and the transverse beam.
[0008] In one embodiment, the dimensions of the block steel plate unit are adapted to the grid dimensions of the cross beam system.
[0009] In one embodiment, the lower deck area is structurally reinforced by thickening or reinforcing steel plates.
[0010] In addition, embodiments of the present invention also provide a vessel, the vessel including a car carrier deck structure as described in any embodiment of the present invention.
[0011] Compared with the prior art, the beneficial effects of the car carrier deck structure and ship provided by the embodiments of the present invention are as follows: The embodiments of the present invention reduce the number of continuous upper decks and change them to a frame structure. Small thin plates are laid on the frame and the structure is reinforced. Under the premise of meeting the structural strength requirements of the hull, the unavoidable large amount of repair work caused by deformation during the cutting, assembly and welding, placement, transfer and overturning hoisting of the thin plates is avoided. This reduces construction costs, reduces construction time, and improves the structural safety and economy of the ship. Attached Figure Description

[0020] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.
[0021] The principles and features of the present invention are described below with reference to the accompanying drawings. The embodiments described are for illustrative purposes only and are not intended to limit the scope of the invention. The following description, in conjunction with... Figure 1-2 The preferred embodiments of the present invention will be described in further detail below: like Figure 1-2 As shown, an embodiment of the present invention provides a deck structure for a car carrier: The lower deck area of the cargo hold is constructed using a continuous thin-plate deck. The deck above the cargo hold is constructed with a steel frame and steel plate. Furthermore, the hull structure strength meets the design requirements.
[0022] In one embodiment, the deck in the upper region includes longitudinal beams 1, transverse beams 2, and block steel plate units 4. The longitudinal beams 1 and transverse beams 2 are arranged along the length and width of the ship, respectively. Several longitudinal beams 1 and transverse beams 2 are fixed in a cross beam system with a frame structure. The block steel plate units 4 are laid and fixed on the frame structure of the cross beam system. Several block steel plate units 4 are connected to each other to form a closed deck surface.
[0023] In one embodiment, to improve the structural safety of the ship, it also includes: Several pillars 3 are arranged at intervals in the cargo hold area along the direction of the vertical deck and are arranged along the length of the ship. Furthermore, the pillars 3 are arranged at the intersection of the longitudinal beam 1 and the transverse beam 2.
[0024] In one embodiment, the size of the block steel plate unit 4 is adapted to the grid size of the cross beam system to ensure that each block steel plate unit 4 can be welded to the cross beam system on all four sides, and that each beam can be welded to the block steel plate unit 4, thereby improving the structural integrity of the deck.
[0025] In one embodiment, the lower deck area is reinforced with thickened or stiffened steel plates to meet the structural strength design requirements of the ship or to further improve the structural safety of the ship.
[0026] In addition, embodiments of the present invention also provide a vessel, the vessel including a car carrier deck structure as described in any embodiment of the present invention.
[0027] In one embodiment, a number of longitudinal beams 1 and transverse beams 2 are provided in the upper area of the cargo hold. The longitudinal beams 1 and transverse beams 2 intersect to form a cross beam system. Small block-shaped steel plate units 4 are arranged on the frame structure of the cross beams. A number of pillars 3 are provided vertically in the cargo hold area. The pillars 3 intersect with the longitudinal beams 1 and transverse beams 2.
[0028] In this embodiment of the invention, the continuous thin-plate deck in the upper region of the cargo hold is replaced with a steel frame structure with intersecting longitudinal and transverse beams. Small steel plates are laid on the steel frame, that is, small steel plates are arranged on the frame structure with intersecting beams to replace the continuous thin-plate deck design, thereby avoiding the bending deformation of the thin plates. At the same time, the deck and related components are strengthened to meet the structural strength requirements of the hull. The thin-plate deck is a continuous deck and participates in the longitudinal strength calculation of the ship. By changing it to a frame structure, the upper thin plate becomes discontinuous and does not participate in the longitudinal strength calculation of the ship. However, due to the large number of deck layers, all of which are continuous decks, the section modulus of the car carrier can still meet the requirements. Due to the small block coefficient, the still water bending moment of the car carrier under various loading conditions is a central camber. After combining with the wave bending moment, the bottom area may be subjected to large bending compressive stress, while the compressive stress on the deck is relatively small after combination. The structural layout scheme of this embodiment of the invention still meets the structural strength requirements of the hull.
[0029] The embodiments of the present invention avoid bending deformation of thin plates, reduce difficulties in the transportation, storage and construction of steel plates, and reduce repeated correction operations due to failure to meet deck flatness requirements, thereby reducing construction costs, reducing construction time, and improving the safety and economy of ship structure.
[0030] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
