[0002] With the rapid development of the modern ship shipping industry and shipbuilding industry, the requirements for installation accuracy during the shipbuilding process are also continuously increasing. For the installation between the corrugated bulkhead and the upper and lower decks, there are certain accuracy requirements. However, during the existing shipbuilding process, when installing the corrugated bulkhead, on-site positioning and welding are often directly carried out, which results in a complex actual operation process, poor installation accuracy, low installation efficiency, and cannot meet the requirements of shipbuilding.

The installation method of the ship corrugated bulkhead provided by this technology is to first fabricate the corrugated bulkhead, then erect the corrugated bulkhead, and finally weld the corrugated bulkhead to the deck. Among them, before erecting the corrugated bulkhead 1, the upper deck to be welded to the corrugated bulkhead is divided into a connecting part 2 and a main part 3 to be welded to the corrugated bulkhead, and the deck of the connecting part is welded to the upper end of the corrugated bulkhead in the state where the corrugated bulkhead lies horizontally. After erecting the corrugated bulkhead welded with the deck of the connecting part, the main part of the deck is then joined with the connecting part. Compared with the prior art, the safety of this welding process is greatly improved, the operation difficulty is greatly reduced, and accordingly, its welding efficiency and welding quality are improved, enabling the corrugated bulkhead to be well formed, saving materials, improving the welding quality, and shortening the dock closing period.

[0012] S5. The centerlines of the bulkhead side plates of the ship bulkhead coincide with the centerlines of the corresponding bulkhead side plates, and the centerlines of the bulkhead middle plates coincide with the centerlines of the corresponding bulkhead middle plates.

[0013] The centerlines of the bulkhead middle plates include multiple lines, and each centerline 4 of the bulkhead middle plates forms an acute angle structure with the centerline of the bulkhead side plate; the 100MK lines of the bulkhead middle plates include multiple lines, and each 100MK line of the bulkhead middle plates forms an acute angle structure with the centerline of the bulkhead side plate.

[0014] Each centerline of the bulkhead side plate is arranged parallel to the corresponding 100MK line of the bulkhead side plate; each centerline of the bulkhead middle plate is arranged parallel to the corresponding 100MK line of the bulkhead middle plate.

[0015] The centerlines of the bulkhead side plates include the first centerline of the bulkhead side plate and the second centerline of the bulkhead side plate, and the first centerline of the bulkhead side plate and the second centerline of the bulkhead side plate are arranged parallel; the bulkhead side plates include the first bulkhead side plate and the second bulkhead side plate.

[0016] The distance between each centerline of the bulkhead side plate and the corresponding parallel 100MK line 5 of the bulkhead side plate is equal to half of the thickness dimension of the bulkhead side plate.

[0017] The distance between each centerline of the bulkhead middle plate and the corresponding parallel 100MK line 6 of the bulkhead middle plate is equal to half of the thickness dimension of the bulkhead middle plate.

[0018] A plurality of marking points are respectively set at the positions of the 100MK lines of the middle plate members of each bulkhead, and the multiple marking points of the 100MK lines of the middle plate members of each bulkhead are in the same straight line position.

Then, the segment plates are welded. After the deck is formed, the ship bulkhead is transported between the corresponding upper and lower decks. Then, the ship bulkhead is positionally adjusted according to the drawn lines. Because there are lines and marking points to rely on, the positional adjustment of the ship bulkhead is fast and accurate. Then welding is carried out. In this way, it is not necessary to repeatedly adjust the position of the ship bulkhead, reducing the complexity of the operation. When welding the ship bulkhead, not only the position with the lower deck is adjusted, but also the position with the upper deck is adjusted to ensure accurate positioning of both the upper and lower decks.

[0030] The following is a further detailed description of the specific implementation manners of the present invention, such as the shapes, structures of the components involved, the mutual positions and connection relationships between the various parts, the functions and working principles of the various parts, etc., with reference to the accompanying drawings and through the description of the embodiments:

[0031] As shown in the attached Figure 1 - attached Figure 5 figures, the present invention is a method for installing a ship bulkhead, and the installation steps of the ship bulkhead installation method are as follows:

[0032] S1. Mark the centerlines 3 of the bulkhead side plates and 4 of the bulkhead middle plates on the upper surface of the bottom deck segment plate 2 of the bottom deck 1. Draw the 100MK lines 5 of the bulkhead side plates parallel to the centerline 3 of the bulkhead side plates, and draw the 100MK lines 6 of the bulkhead middle plates parallel to the centerline 4 of the bulkhead middle plates. Mark multiple marking points 7 at intervals along the 100MK lines 5 of the bulkhead side plates, and mark multiple marking points 7 at intervals along the 100MK lines 6 of the bulkhead middle plates; S2. Mark the centerlines 3 of the bulkhead side plates and 4 of the bulkhead middle plates on the lower surface of the top deck segment plate 9 of the top deck 8. Draw the 100MK lines 5 of the bulkhead side plates parallel to the centerline 3 of the bulkhead side plates, and draw the 100MK lines 6 of the bulkhead middle plates parallel to the centerline 4 of the bulkhead middle plates; S3. The ship bulkhead includes the bulkhead side plates 10 and the bulkhead middle plates 11; S4. After the ship is built, weld the ship bulkhead between the bottom deck 1 and the top deck 8 with the bottom deck segment plate 2 of the bottom deck 1 and the top deck segment plate 9 of the top deck 8; S5. The centerline of the bulkhead side plate 10 of the ship bulkhead coincides with the centerline 3 of the bulkhead side plates, and the centerline of the bulkhead middle plate 11 coincides with the centerline 4 of the bulkhead middle plates. The above steps propose an improved technical solution for the deficiencies in the prior art. During the shipbuilding process, to improve the installation accuracy of the ship bulkhead between the upper and lower decks, the installation method of the present invention is used. The key point of the installation method of the present invention is that before the deck is formed, pre-scribe lines on the segment plates where the ship bulkhead needs to be welded respectively. The lines include the centerline 3 of the bulkhead side plates, the centerline 4 of the bulkhead middle plates, the 100MK lines 5 of the bulkhead side plates, and the 100MK lines 6 of the bulkhead middle plates, and mark the marking points 7 on different lines respectively. When the centerline 3 of the bulkhead side plates, the centerline 4 of the bulkhead middle plates, the 100MK lines 5 of the bulkhead side plates, and the 100MK lines 6 of the bulkhead middle plates are drawn, they are drawn according to the model and size of the ship bulkhead of the specific ship. Then, the segment plates are welded. After the deck is formed, the ship bulkhead is transported between the corresponding upper and lower decks, and then the position of the ship bulkhead is adjusted according to the drawn lines. Because there are lines and marking points to rely on, the position adjustment of the ship bulkhead is fast and accurate, and then welding is carried out. In this way, it is not necessary to repeatedly adjust the position of the ship bulkhead, reducing the complexity of the operation. When the ship bulkhead is welded, not only the position with the lower deck is adjusted, but also the position with the upper deck is adjusted to ensure accurate positioning of both the upper and lower decks. The ship bulkhead installation method described in the present invention has simple steps. When the ship bulkhead is connected to the deck, it effectively guarantees the positioning accuracy between the ship bulkhead and the deck, improves the installation efficiency, and simplifies the operation process.

[0033] The center lines 4 of the middle plates of the bulkhead include multiple lines, and each center line 4 of the middle plates of the bulkhead forms an acute angle structure with the center line 3 of the side plates of the bulkhead; the 100MK lines 6 of the middle plates of the bulkhead include multiple lines, and each 100MK line 6 of the middle plates of the bulkhead forms an acute angle structure with the center line 3 of the side plates of the bulkhead. The above steps define the layout relationship between the center line 4 of the middle plates of the bulkhead and the center line 3 of the side plates of the bulkhead, and define the layout relationship between the 100MK line 6 of the middle plates of the bulkhead and the center line 3 of the side plates of the bulkhead, adapting to the structure of the ship bulkhead.

[0034] Each center line 3 of the side plates of the bulkhead is arranged in parallel with a corresponding 100MK line 5 of the side plates of the bulkhead; each center line 4 of the middle plates of the bulkhead is arranged in parallel with a corresponding 100MK line 6 of the middle plates of the bulkhead. The above steps define the layout of the center line 3 of the side plates of the bulkhead and the corresponding 100MK line 5, and define the layout of the center line 4 of the middle plates of the bulkhead and the corresponding 100MK line 6 arranged in parallel, adapting to the structure of the ship bulkhead.

[0035] The center line 3 of the side plates of the bulkhead includes the first center line 12 of the side plates of the bulkhead and the second center line 13 of the side plates of the bulkhead, and the first center line 12 of the side plates of the bulkhead and the second center line 13 of the side plates of the bulkhead are arranged in parallel; the bulkhead side part 10 includes the first bulkhead side plate 14 and the second bulkhead side plate 15. The above steps define the center line. Ensure the cooperation between the center line and the 100MK line to achieve precise limitation of the position during the layout of the ship bulkhead.

[0036] The distance between each center line 3 of the side plates of the bulkhead and a corresponding parallel 100MK line 5 of the side plates of the bulkhead is equal to half of the thickness dimension of the bulkhead side part 10. In the above steps, when arranging the ship bulkhead, the center line of the ship bulkhead coincides with the center line 3 of the side plates of the bulkhead, achieving precise position limitation and ensuring the accuracy of the overall layout of the ship bulkhead.

[0037] The distance between each center line 4 of the middle plates of the bulkhead and a corresponding parallel 100MK line 6 of the middle plates of the bulkhead is equal to half of the thickness dimension of the bulkhead middle part 11. In the above steps, when arranging the ship bulkhead, the center line of the ship bulkhead coincides with the center line of the bulkhead middle part 11, achieving precise position limitation and ensuring the accuracy of the overall layout of the ship bulkhead.

[0038] A plurality of marking points 7 are respectively arranged at the positions of each 100MK line 6 of the middle plates of the bulkhead, and the plurality of marking points 7 of each 100MK line 6 of the middle plates of the bulkhead are in the same straight line position. After the marking points of the sectional plate of the present invention are defined, they need to be protected with tape to avoid abrasion and removal of the protection points during the transportation or welding of the sectional plate. Before the ship bulkhead is moved into place, the tape is removed.

[0039] A plurality of intermediate decks 16 are provided between the underlying deck 1 and the top deck 8. On the upper and lower surfaces of the intermediate deck sectional plate 17 of each intermediate deck 16, the center lines 3 of the bulkhead edge plates and the center lines 4 of the bulkhead middle plates are respectively marked. On the upper and lower surfaces of the intermediate deck sectional plate 17 of each intermediate deck 16, the 100MK lines 5 of the bulkhead edge plates are drawn parallel to the center line 3 of the bulkhead edge plates, and the 100MK lines 6 of the bulkhead middle plates are drawn parallel to the center line 4 of the bulkhead middle plates. A plurality of marking points 7 are marked on the 100MK line 6 of the bulkhead middle plates. In the above structure, according to the height requirements of different ships, the storey height of the ship is different. Therefore, according to actual needs, different numbers of intermediate decks can be set, and the corresponding number of ship bulkheads are welded between the upper and lower adjacent decks. For the surfaces of the clamping plates where the ship bulkheads need to be welded, scribing needs to be carried out in advance.

[0040] When the ship bulkhead 18 is welded, the bottom of the bulkhead edge plate 10 and the bulkhead middle plate 11 are welded to the corresponding underlying deck, the top of the bulkhead edge plate 10 and the bulkhead middle plate 11 of the ship bulkhead 18 are welded to the corresponding upper deck, and the ends of the adjacent bulkhead middle plates 11 of the ship bulkhead are welded and connected. In the above structure, when different ship bulkheads are connected to the ship deck, reliable connection is achieved through welding. The upper and lower parts of the adjacent bulkhead middle plates are respectively welded to the corresponding decks, and the end welding also improves the welding strength of the bulkhead middle plates.

[0041] For the ship bulkhead installation method of the present invention, during the ship construction process, in order to improve the installation accuracy of the ship bulkhead between the upper and lower decks, the installation method of the present invention is adopted. The key point of the installation method of the present invention is that before the deck is formed, scribing is respectively carried out in advance on the sectional plates where the ship bulkheads need to be welded. The scribing includes the center line 3 of the bulkhead edge plates, the center line 4 of the bulkhead middle plates, the 100MK line 5 of the bulkhead edge plates, the 100MK line 6 of the bulkhead middle plates, and marking points 7 are respectively marked on different lines. When the center line 3 of the bulkhead edge plates, the center line 4 of the bulkhead middle plates, the 100MK line 5 of the bulkhead edge plates, and the 100MK line 6 of the bulkhead middle plates are defined, they are defined according to the model and size of the ship bulkheads of the specific ship. Therefore, the present invention can be used for different ships. Then sectional plate welding is carried out. After the deck is formed, the ship bulkheads are transported to between the corresponding upper and lower decks, and then the ship bulkheads are position-adjusted according to the defined lines. Because there are scribing and marking points to rely on, the position adjustment of the ship bulkheads is fast and accurate. Then welding is carried out. In this way, it is not necessary to repeatedly adjust the position of the ship bulkheads, reducing the complexity of the operation. When the ship bulkheads are welded, not only the position with the underlying deck is adjusted, but also the position with the upper deck is adjusted to ensure accurate positioning of both the upper and lower decks.

[0042] The present invention has been described exemplarily in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above-mentioned manner. As long as various improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
