Description

Technical Field

[0001] This utility model relates to the field of extended bulkhead installation technology, specifically to a B-15 class bulkhead extension structure and a bulkhead containing the structure. Background Technology

[0002] In the shipbuilding industry, due to requirements for bulkhead strength, weight, and wiring, bulkheads are generally composed of a lower bulkhead panel and an upper bulkhead extension structure. This type of bulkhead construction is particularly common on luxury cruise ships. The main function of the bulkhead extension structure is to enhance the overall structural strength and sealing of the hull by expanding the boundaries of the enclosed space. In the event of a collision, grounding, or other accidents, it effectively prevents seawater or other media from intruding into the core area of ​​the hull, providing additional safety protection for the equipment and personnel inside. Simultaneously, the extended bulkhead can be divided into more independent compartments according to functional needs for arranging equipment, storing supplies, or optimizing the internal space layout, thereby improving the space utilization and operational safety of the vessel.

[0003] The existing extended bulkhead installation structure has poor sealing performance at the joints, and the sealing materials used mostly lack flame retardant properties, making it difficult to meet both sealing and fire protection requirements. The joint structure design is unreasonable, and the complex fixing methods, such as relying heavily on screws for fastening, often lead to difficulties in splicing and low efficiency.

[0004] Based on this, a B-15 class bulkhead extension structure is now offered, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide a B-15 class bulkhead extension structure to solve the problems in the prior art where the splicing structure design is unreasonable, and the splicing is difficult and inefficient due to the complex fixing method, such as the heavy reliance on screw fastening.

[0006] To achieve the above objectives, this utility model provides the following technical solution: The B-15 class bulkhead extension structure includes a first bulkhead panel and a second bulkhead panel. One end of the first bulkhead panel and the second bulkhead panel are chamfered, and a first sealant is filled between the two chamfers. The top of both the first and second bulkhead panels is provided with a first positioning hole, and a splicing mechanism is provided between the first and second bulkhead panels.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative: the splicing mechanism includes a stud, the two ends of which pass through the first bulkhead and the second bulkhead respectively through two first positioning holes, and locking plates are fitted on the outside of both ends of the stud, and the two ends of the stud are bent after passing through.

[0008] In one alternative: the first bulkhead panel includes a base layer, a fireproof layer is provided on one side of the base layer, and a reinforcing layer is provided on one side of the fireproof layer.

[0009] In one alternative: the base layer is made of rock wool, the fireproof layer is made of intumescent fireproof coating, and the reinforcing layer is made of aluminum foil.

[0010] A bulkhead includes a third bulkhead panel, above which a B-15 class bulkhead extension structure is provided.

[0011] In one alternative: a first reinforcing plate and a second reinforcing plate are respectively provided on both sides of the connection between the third bulkhead and the B-15 class bulkhead extension structure.

[0012] In one alternative: a second sealant is used to fill the space between the third bulkhead panel and the B-15 class bulkhead extension structure.

[0013] In one alternative: dovetail nails are passed through both the first and second reinforcing plates, and the dovetail nails are inserted into the third bulkhead.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention achieves both excellent sealing and flame retardant properties through chamfered splicing combined with non-combustible sealant filling. The splicing mechanism uses a pin penetrating the first positioning hole, along with locking plates and bending for fixation, increasing the contact area and making the splicing of the first and second bulkhead panels stable, reducing splicing difficulty and improving splicing efficiency and quality. In addition, the first bulkhead panel adopts a composite structure of rock wool base layer, intumescent fireproof coating fireproof layer and aluminum foil facing reinforcement layer. Through the multiple effects of heat insulation, carbonization layer heat insulation and reflection of radiant heat, it achieves the B-15 fire resistance standard, significantly improving flame retardancy and heat insulation effect.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] First embodiment: In one embodiment, such as Figures 1-3 As shown, the B-15 class bulkhead extension structure includes a first bulkhead panel 1 and a second bulkhead panel 2. One end of the first bulkhead panel 1 and the second bulkhead panel 2 is provided with a chamfer 3, and a first sealant 4 is filled between the two chamfers 3. The top of both the first bulkhead 1 and the second bulkhead 2 is provided with a first positioning hole 5, and a splicing mechanism is provided between the first bulkhead 1 and the second bulkhead 2.

[0023] In this embodiment, the first bulkhead panel 1 and the second bulkhead panel 2 are first spliced ​​together by chamfering 3. Then, the joint between the first bulkhead panel 1 and the second bulkhead panel 2 is filled with a first sealant 4. The first sealant 4 is made of non-flammable sealant, which has flame-retardant function while sealing. Then, the first bulkhead panel 1 and the second bulkhead panel 2 can be quickly and stably fixed by the splicing mechanism, which reduces the splicing difficulty and improves the efficiency and quality of splicing.

[0024] In one embodiment, such as Figure 1 and Figure 2 As shown, the splicing mechanism includes a rivet 6. The two ends of the rivet 6 pass through the first bulkhead 1 and the second bulkhead 2 respectively through two first positioning holes 5. Locking pieces 7 are fitted on the outside of both ends of the rivet 6. After the two ends of the rivet 6 pass through, they are bent. After the first sealant 4 is filled, the two ends of the rivet 6 pass through the first positioning holes 5 respectively through the first bulkhead 1 and the second bulkhead 2. Then, locking pieces 7 are fitted on the outside of both ends of the rivet 6, so that the two locking pieces 7 are tightly attached to the bottom of the first bulkhead 1 and the second bulkhead 2 respectively. Finally, the two ends of the rivet 6 are bent. The setting of the locking pieces 7 increases the contact area between the bent end of the rivet 6 and the first bulkhead 1 or the second bulkhead 2, making the splicing more stable.

[0025] In one embodiment, such as Figure 1 and Figure 3As shown, the first bulkhead panel 1 includes a base layer 101, a fireproof layer 102 is provided on one side of the base layer 101, and a reinforcing layer 103 is provided on one side of the fireproof layer 102. The base layer 101 is made of rock wool, the fireproof layer 102 is made of intumescent fireproof coating, and the reinforcing layer 103 is aluminum foil facing. The base layer 101 provides core heat insulation, the fireproof layer 102 forms a dense carbonized layer at high temperature, which slows down heat transfer and further improves the heat insulation effect, and the reinforcing layer 103 reflects radiant heat and slows down temperature rise, which further improves flame retardancy, so that it meets the B-15 fire resistance standard.

[0026] Second embodiment: In one embodiment, such as Figures 4-5 As shown, a bulkhead includes a third bulkhead panel 11, with a B-15 class bulkhead extension structure above the third bulkhead panel 11. A first reinforcing plate 12 and a second reinforcing plate 13 are respectively provided on both sides of the connection between the third bulkhead panel and the B-15 class bulkhead extension structure.

[0027] In this embodiment, the first bulkhead panel 1 can be made of rock wool, glass wool, or other fiber insulation board; the second bulkhead panel 2 can be made of rock wool, glass wool, or other fiber insulation board; and the third bulkhead panel 11 can be made of wood, aluminum, steel, or other high-strength sheet material. Both the first reinforcing plate 12 and the second reinforcing plate 13 can be made of galvanized sheet.

[0028] Among them, such as Figure 5 As shown, a second sealant 15 is filled between the third bulkhead panel and the B-15 class bulkhead extension structure. The second sealant 15 is made of non-flammable sealant, providing both sealing and flame-retardant properties. The connection between the B-15 class bulkhead extension structure and the third bulkhead panel is a flexible connection, using non-flammable sealant for bonding and fixing. This non-rigid connection provides vibration resistance and noise reduction. Furthermore, in the event of a fire, the connection between the B-15 class bulkhead extension structure and the third bulkhead panel is prone to severe deformation due to high temperatures; this non-rigid connection structure prevents the overall structural collapse or damage caused by stress concentration due to deformation.

[0029] Dovetail nails 14 are passed through both the first reinforcing plate 12 and the second reinforcing plate 13, and the dovetail nails 14 penetrate into the third bulkhead plate 11. Therefore, the first reinforcing plate 12 and the second reinforcing plate 13 can be connected to the third bulkhead plate 11 through the dovetail nails 14 to ensure the effectiveness of the bulkhead.

[0030] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
