Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to an integrated log structure for ships and its manufacturing and installation method. Background Technology

[0002] A hull stilt is an appendage structure installed on the hull of a ship. It generally does not serve a structural function and is mainly used to fill or transition the shape of the hull. The stern stilt does not participate in the main load-bearing or structural support of the hull and is usually used to optimize the hydrodynamic performance of the underwater sections.

[0003] In existing technology, the stern stern post is generally spindle-shaped, a streamlined structure that is slender at the front and rear and wide in the middle. It is made of the same material as the hull and welded separately to the outer plating. Due to its slender structure, its fabrication and installation are very difficult, especially the transition connection between the bow and the bottom of the hull. Furthermore, the stern post is large in volume and has a dense internal structure, not only consuming a portion of the hull's weight but also being unconnected to the hull, resulting in wasted space. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated ship hull structure and its manufacturing and installation method. The hull structure is connected to the ship hull structure as one unit, which increases structural strength, reduces construction difficulty, improves installation efficiency, and increases the bottom volume of the ship hull.

[0005] To achieve the above objectives, the present invention provides an integrated log structure for ships, comprising a bottom plate, side plates, end plates, a top plate, longitudinal bulkheads, a first transverse bulkhead, and a second transverse bulkhead. Two side plates are provided and respectively disposed on both sides of the bottom plate. The end plate is disposed at the end of the bottom plate. A log cavity is formed between the two side plates, the bottom plate, and the end plate. The front end of the bottom plate is connected to the hull hull plating. The bottom plate is flush with the bottom surface of the ship. The width of the rear section of the bottom plate gradually decreases. The longitudinal bulkheads are disposed along the longitudinal direction of the bottom plate in the middle of the bottom plate. The longitudinal bulkheads include a front section and a rear section, with the height of the front section being higher than the height of the rear section.

[0006] Multiple first transverse bulkheads are provided and spaced apart on the front section of the longitudinal bulkhead. The first transverse bulkheads and the front section of the longitudinal bulkheads are at the same height. The upper parts of the front section of the longitudinal bulkheads and the upper parts of the first transverse bulkheads both extend out of the wooden cavity and into the hull. The proximal end of the front section of the longitudinal bulkheads is connected to the inner keel of the hull. The upper two sides of the first transverse bulkheads are respectively connected to the hull ribs. The proximal ends of the side plates are connected to the longitudinal structure of the hull. Multiple second transverse bulkheads are provided and spaced apart on the rear section of the longitudinal bulkheads. The two sides of the second transverse bulkheads are respectively connected to the inner sidewalls of the two side plates. The top plate is installed on the rear section of the wooden cavity and faces the rear section of the longitudinal bulkheads. The side plates and the sealing plate are connected to the outer hull plates.

[0007] As a preferred embodiment of the present invention, the top plate matches the shape of the hull hull plating, the top surface of the top plate is connected to the inner keel of the hull, and the bottom surface of the top plate is connected to the second transverse bulkhead and the rear section of the longitudinal bulkhead.

[0008] As a preferred embodiment of the present invention, the rear part of the wooden cavity is provided with a plurality of horizontal partitions arranged at intervals along the height direction of the wooden cavity, the front end of the horizontal partitions is connected to the second horizontal partition, and the rear end of the horizontal partitions is separate from the sealing plate.

[0009] As a preferred embodiment of the present invention, the first transverse bulkhead includes a plurality of first bulkheads disposed in the front section of the front section of the longitudinal bulkhead and a plurality of second bulkheads disposed in the rear section of the front section of the longitudinal bulkhead. The first section of the side plate is provided with a raised portion, and the upper sides of the first bulkhead are respectively connected to two of the raised portions. The first bulkhead is connected to the hull ribs through the raised portions.

[0010] As a preferred embodiment of the present invention, the upper width of the second partition is greater than the width of the bottom plate, the second partition has a slot for inserting into the top of the side plate, and the upper two sides of the second partition are connected to the ribs of the hull.

[0011] As a preferred embodiment of the present invention, the second partition is provided with reinforcing ribs.

[0012] As a preferred embodiment of the present invention, the top of the side plate extends into the hull.

[0013] As a preferred embodiment of the present invention, the longitudinal partition, the first transverse partition, and the second transverse partition all have manholes, drainage holes, and ventilation holes.

[0014] This invention also provides a method for manufacturing and installing an integrated shipboard log structure, comprising the following steps:

[0015] Step 1: Place the base plate on the installation platform, first position and install the rear section of the longitudinal partition on the base plate, and then install the second transverse partition.

[0016] Step 2: First, position and install the front section of the longitudinal diaphragm on the base plate, then install the first transverse diaphragm located at the front section of the longitudinal diaphragm, then install the two side plates, and then install the remaining first transverse diaphragms.

Detailed Implementation

[0039] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0040] In the description of this invention, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0041] like Figures 1 to 13 As shown, a preferred embodiment of the present invention provides a ship integrated log structure, including a bottom plate 1, side plates 2, sealing plates 3, a top plate 4, longitudinal bulkheads 5, a first transverse bulkhead 6, and a second transverse bulkhead 7. Two side plates 2 are provided and respectively disposed on both sides of the bottom plate 1. The sealing plate 3 is disposed at the end of the bottom plate 1. A log cavity is formed between the two side plates 2, the bottom plate 1, and the sealing plate 3. The bow end of the bottom plate 1 is connected to the hull outer plate 91. The bottom plate 1 is flush with the bottom base surface. The width of the rear section of the bottom plate 1 gradually decreases, and the log structure gradually transitions into a hull structure from the end to the bow. The longitudinal bulkheads 5 are disposed in the middle of the bottom plate 1 along the longitudinal direction of the bottom plate 1. The longitudinal bulkhead 5 includes a front section 51 and a rear section 52, with the height of the front section 51 being higher than the height of the rear section 52.

[0042] Multiple first transverse bulkheads 6 are provided and spaced apart on the front section 51 of the longitudinal bulkhead. The first transverse bulkheads 6 are symmetrically arranged on the left and right sides of the front section 51 of the longitudinal bulkhead. The first transverse bulkheads 6 are at the same height as the front section 51 of the longitudinal bulkhead. The upper parts of the front section 51 of the longitudinal bulkhead and the upper parts of the first transverse bulkheads 6 both extend out of the wooden cavity and into the hull. The bow end of the front section 51 of the longitudinal bulkhead is connected to the inner keel 92 of the hull. The upper sides of the first transverse bulkheads 6 are respectively connected to the hull... The ribs 93 of the body are joined together, and the front end of the side plate 2 is connected to the longitudinal structure of the hull; multiple second transverse bulkheads 7 are provided and spaced apart on the rear section 52 of the longitudinal bulkhead. The second transverse bulkheads 7 are symmetrically arranged on the left and right sides of the rear section 52 of the longitudinal bulkhead. The two sides of the second transverse bulkheads 7 are respectively connected to the inner sidewalls of the two side plates 2. The top plate 4 is installed on the rear section of the wooden cavity and faces the rear section 52 of the longitudinal bulkhead. The side plates 2 and the sealing plate 3 are connected to the outer plate 91 of the hull.

[0043] For example, the top plate 4 matches the line shape of the outer hull plate 91, the top surface of the top plate 4 is connected to the inner keel 92 of the hull, and the bottom surface of the top plate 4 is connected to the second transverse bulkhead 7 and the rear section 52 of the longitudinal bulkhead, thereby improving the connection strength between the log structure and the hull.

[0044] For example, the rear part of the wooden cavity is provided with a plurality of horizontal partitions 8 arranged at intervals along the height direction of the wooden cavity. The front end of the horizontal partition 8 is connected to the second transverse partition 7, and the rear end of the horizontal partition 8 is separated from the sealing plate 3. Figure 6 As shown, the horizontal partition 8 and the sealing plate 3 maintain a 35mm gap. Specifically, the two sides of the horizontal partition 8 are welded to the side plate 2 to ensure the structural strength of the rear of the log structure.

[0045] Specifically, the first transverse bulkhead 6 includes several first bulkheads 61 disposed at the front section of the front section 51 of the longitudinal bulkhead and several second bulkheads 62 disposed at the rear section of the front section 51 of the longitudinal bulkhead. The first section of the side plate 2 is provided with a raised part 21. The upper sides of the first bulkhead 61 are respectively connected to two raised parts 21. The first bulkhead 61 is connected to the hull rib 93 through the raised part 21. The side plate 2 extends forward and penetrates into the hull. The forward end of the side plate 2 is connected to the longitudinal structure of the hull (side inner keel 94) to increase the structural strength.

[0046] For example, the upper width of the second partition 62 is greater than the width of the bottom plate 1. The second partition 62 has a slot 621 that is inserted into the top of the side plate 2, which facilitates the positioning and installation of the second partition 62 and the side plate 2. The upper two sides of the second partition 62 are directly connected to the rib plate 93 of the hull, which improves the connection stability between the log structure and the hull.

[0047] Furthermore, each of the second bulkheads 62 is provided with reinforcing ribs 622, and the second bulkheads 62 also serve as ribs 93 of the hull structure, ensuring high structural strength of the second bulkheads 62.

[0048] For example, such as Figure 10 and 11 As shown, the top of the side plate 2 extends into the hull, and the distance between the top surface of the side plate 2 (the top surface of the sealing plate 3) and the top plate 4 is 25mm, which improves the connection stability between the log structure and the hull.

[0049] Specifically, the longitudinal partition 5, the first transverse partition 6, and the second transverse partition 7 all have manholes, drainage holes, and ventilation holes.

[0050] This invention also discloses a method for manufacturing and installing an integrated shipboard log structure, comprising the following steps:

[0051] Step 1: Place the base plate 1 on the installation platform, first position and install the rear section 52 of the longitudinal partition plate on the base plate 1, and then install the second transverse partition plate 7.

[0052] Step 2: First, position and install the front section 51 of the longitudinal partition plate on the base plate 1, then install the first transverse partition plate 6 located at the front section of the longitudinal partition plate 51, then install the two side plates 2, and then install the remaining first transverse partition plates 6; specifically, first install the first partition plate 61, then install the two side plates 2, and finally install the second partition plate 62.

[0053] Step 3: Install the top plate 4 to complete the construction of the log structure;

[0054] Step 4: The log structure is flipped and hoisted onto the inverted hull section. The outer hull plate 91 of the reserved perimeter of the log structure on the hull section is not installed yet. The hull section is constructed in an inverted manner. After the log structure is flipped, it is installed onto the inverted hull section to improve the installation efficiency of the log structure.

[0055] Step 5: Align the bottom plate 1 with the flat keel 911 of the outer hull plate 91, align the side plate 2 with the side inner keel 94, align the longitudinal bulkhead 5 with the central inner keel 92, and align the first transverse bulkhead 6 and the second transverse bulkhead 7 with the hull ribs 93 one-to-one, and weld them together; the flat keel 911 is part of the outer hull plate 91, referring to a row of longitudinal steel plates located on the centerline surface of the bottom of the ship; the longitudinal hull frame includes the central inner keel 92, the side inner keel 94, and the longitudinal keel, and the longitudinal hull frame is used to enhance the longitudinal strength of the hull;

[0056] Step 6: Install the outer hull plating 91 of the wooden structure perimeter.

[0057] Specifically, in step 2, after the first transverse partition 6 is installed, the horizontal partition 8 is installed inside the rear of the wooden cavity.

[0058] In summary, the log structure of the present invention is integrated with the hull structure, and the first transverse bulkhead 6 and the rib plate 93 are connected to form an integral unit. This not only increases the structural strength, but also changes the pointed and slender shape of the existing log structure, reduces the construction difficulty, and improves the installation efficiency. Moreover, the internal space of the log structure is connected to the internal space of the hull, and the log structure space can serve as part of the ballast tank at the bottom of the hull, thereby expanding the ballast volume of the bottom compartment of the hull.

[0059] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0060] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
