Description

Ship structure reinforcement and ship manufacturing method

Technical Field

The invention belongs to the technical field of ship design and manufacture, and particularly relates to a ship structure reinforcing and ship manufacturing method.

Background

In the design or construction process of a ship structure, bulkheads are usually added in cabins or public places to reinforce the ship structure due to insufficient strength, severe vibration, excessive deformation between upper and lower deck boards and the like; for example, when the passenger roller is subjected to full load test or test under severe working conditions before outfitting, when the total longitudinal strength of the ship body does not meet corresponding standards, that is, when the deformation of the ship body is too large, the deformation of a cabin on the ship is too large, the cabin door is not opened and closed well, and even the cabin window is damaged due to the too large deformation of the cabin; for another example, when the strength of the deck of the ship is insufficient, the power equipment used for loading the cargo may generate large vibration and conduct through the deck.

In the prior art, a conventional mode of plate reinforcement (steel wall) is generally adopted, and a partition is formed at the position where the bulkhead is arranged in the conventional mode, so that the space is divided; the bulkhead of this type has the problems that the position where the bulkhead is arranged is divided, the space is divided into two parts, or a barrier similar to a screen is formed, the arrangement and the space utilization of the cabin interior are greatly influenced, especially for passenger ships with high aesthetic requirements, the arrangement of the bulkhead can greatly influence the aesthetic property and the permeability of the cabin or a public area, the ventilation, the lighting, the illumination and the like are greatly influenced, and the reinforcement of the form cannot be realized due to the aesthetic property and the artistic requirement of partial positions, so that a more permeable structural form is required to replace the position. Further, although the steel wall in the above form can solve the structural strength problem, the permeability and the aesthetic property of the superstructure are often greatly affected due to the small number of openings (the structural strength of the steel wall is affected by too many openings) and the shielding, especially in the position with a large-area public area, the traditional steel wall can greatly affect the space and arrangement of the whole public area, and the redesign of the whole public area is often caused.

Disclosure of Invention

In view of the above, the present invention provides a method for strengthening a ship structure and manufacturing a ship without changing the original cabin layout and the requirements of ventilation and lighting.

In order to solve the technical problems, the technical scheme adopted by the invention is as follows:

a ship structure strengthening method comprises the steps of determining a cabin needing structure strengthening in a ship, arranging a truss unit in the cabin, wherein the truss unit is arranged between a top wall and a bottom wall in the cabin, the truss unit at least comprises two first cylinders and two second cylinders, the first cylinders are arranged at intervals in the transverse direction, two ends of each first cylinder are fixedly connected with the top wall and the bottom wall of the cabin respectively, two ends of each second cylinder are fixedly connected with the two first cylinders respectively, and the second cylinders are crossed.

As a further improvement of the ship structure reinforcing method, a first wall plate is arranged between the top wall of the cabin and the second column, and a first end of the first wall plate is fixedly connected with the top wall of the cabin in the longitudinal direction, and a second end of the first wall plate extends towards the bottom wall of the cabin.

As a further improvement of the ship structure reinforcing method, one end of the second column is close to the second end of the first wall plate, and the other end is far away from the first wall plate.

As a further improvement of the ship structure reinforcing method, the ship structure reinforcing device further comprises a first toggle plate, wherein one end of the first toggle plate is fixed with the second column, and the other end of the first toggle plate is fixedly connected with the first wall plate or the top wall of the cabin.

As a further improvement of the ship structure reinforcing method, one end of the second column is close to the second end of the second wall plate, and the other end is far away from the second wall plate.

As a further improvement of the ship structure reinforcing method, the ship structure reinforcing method further comprises a second toggle plate, wherein one end of the second toggle plate is fixed with the second column body, and the other end of the second toggle plate is fixedly connected with the second wall plate or the bottom wall of the cabin.

As a further improvement of the ship structure reinforcing method, the intersection of the two second columns is fixed with each other.

Detailed Description

The present invention will be described in further detail with reference to the drawings and specific examples so that those skilled in the art can better understand the present invention and can implement the present invention, but the examples are not intended to limit the present invention, and in the present examples, it should be understood that the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element and be integral therewith, or intervening elements may also be present. The terms "mounted," "one end," "the other end," and the like as used herein are for illustrative purposes only.

As shown in fig. 1-2, the present embodiment provides a ship structure strengthening method, which determines a cabin in a ship that needs to be structurally strengthened, for example, after comprehensively testing the total longitudinal strength, the torsional strength, or the transverse strength of a ship before outfitting, it is found that the ship body structure needs to be further improved or strengthened during the building process; at this time, the truss units 1 are arranged in the cabin interior or the common area between two decks which need to be structurally reinforced in the ship body, and the truss units 1 are arranged between the top wall and the bottom wall in the cabin, wherein the top wall and the bottom wall in the cabin refer to an upper deck 2 and a lower deck 3 in the ship body respectively. Every truss unit 1 includes two piece at least first cylinders 11 and second cylinders 12, and in the transverse direction, first cylinder 11 sets up at interval each other, and the both ends of first cylinder 11 respectively with the roof and the diapire of cabin through welding or bolt fastening, the one end of first cylinder 11 is fixed with upper deck 2 promptly, the other end of first cylinder 11 is fixed with lower deck 3, the both ends of second cylinder 12 respectively with two first cylinders 11 fixed connection, and form X type alternately between the second cylinder 12. Of course, a plurality of truss units 1 may be provided with respect to the length or width direction of the cabin, and when there are a plurality of truss units 1, the truss units 1 adjacent to each other may share one first column 11. In particular, the two perpendicular first columns 11 function to provide longitudinal support while adding local stiffness to solve problems such as deck vibration, and in addition together with the two intersecting second columns 12 resist relative displacement between the upper deck 2 and the lower deck 3 in the "X" direction as shown. The effect of the two intersecting second columns 12 is to resist the relative displacement between the decks 1 and 2 in the direction "X" as shown, and if there are no intersecting columns to resist the relative displacement, the relative misalignment of the decks 1 and 2 during the overall longitudinal deformation of the ship will result in increased stress on the openings of windows, doors, etc. on the perimeter walls connected between the upper deck 2 and the lower deck 3, i.e. when the deformation is increased, the windows and door openings will be distorted from square to parallelogram, which will cause the hull structure to be damaged, and the windows and doors will also be damaged, so the deformation control function is very critical. The cross truss type combined structure is provided for strengthening the hull structure in public areas inside or outside the ship cabin due to requirements of strength, deformation, vibration and the like of the hull structure, and has the advantages that on the premise that the strength and the rigidity of the cabin wall with common plates for reinforcement are the same, shielding of the space is reduced as much as possible, influence on attractiveness, permeability and usability is reduced as little as possible under the condition of solving the problem of results, and the problem that cabin arrangement needs to be greatly modified due to structural strength is avoided, so that the usability of the cabin is reduced.

As shown in fig. 1-2, in the preferred embodiment, a first wall plate 4 is disposed between the top wall of the cabin and a second column 12, and a first end of the first wall plate 4 is fixed to the top wall of the cabin or the upper deck 2 by welding in the longitudinal direction, and a second end of the first wall plate 4 extends toward the bottom wall of the cabin; further, the second post 12 has one end near the second end of the first wall 4 and the other end away from the first wall 4. Further, a second wall plate 5 is arranged between the bottom wall of the cabin and the second column 12, in the longitudinal direction, a first end of the second wall plate 5 is fixed with the bottom wall of the cabin or the bottom deck 3 through welding, and a second end of the second wall plate 5 extends towards the top wall of the cabin; further, the second post 12 has one end near the second end of the second wall 5 and the other end away from the second wall 5. Specifically, the combined structure includes a combined cross truss and a partial wall plate, wherein the partial wall plate or the first wall plate 4 and the second wall plate 5 are generally located between the top and bottom second columns 12 of the truss unit 1, and the two vertical square tube columns and the structure between the two vertical square tube columns form a truss unit, and the units can be combined according to actual conditions in the specific use process, for example, the combined structure shown in the drawing is formed by 3 truss combined units. The first wall plate 4 and the second wall plate 5 at the upper end and the lower end are used for increasing the rigidity and the strength of the end part of the truss unit 1, reducing the stress concentration to a certain extent, and flexibly adjusting the size (such as the height) according to specific conditions. Usually, the first wall plate 4 at the upper end is as high as deck beams or stringers at other positions, so that the arrangement of a cabin is not influenced, when the second wall plate 5 at the lower end is furniture such as a table, a chair and the like on the ground, the furniture is arranged in a wall plate sticking mode, and the wall plate can be hidden only if the height of the second wall plate 5 is lower than that of the furniture, so that the effect of meeting the strength requirement and not influencing the arrangement is achieved. The upper or lower first wall 4 or second wall 5 may be omitted if it is not possible to add it for reasons of layout.

As shown in fig. 1-2, in the preferred embodiment, a first toggle plate 6 is further included, and one end of the first toggle plate 6 is fixed to the second column 12, and the other end is fixed to the first wall plate 4 or the top wall of the cabin by welding. Furthermore, the device also comprises a second toggle plate 7, wherein one end of the second toggle plate 7 is fixed with the second column body 12, and the other end is fixed with the second wall plate 5 or the bottom wall of the cabin through welding. In particular, the first and

second toggle plates

6 and 7 function to solve the problem of stress concentration at the intersection of the second column 12 and the first column 11, and if there is no first or second wall plate 4 or 5, the first and

second toggle plates

6 and 7 can be attached to the upper deck 2 and the lower deck 3, respectively. Furthermore, the intersection of the two second columns 12 is fixed to each other, and the first columns 11 and the upper and lower decks are matched to form a plurality of triangles for the truss unit 1, so that the structural rigidity of the truss unit 1 is further improved.
