Horizontal connection structure between deck steel profiles and hangar titanium alloy structure

Abstract

This invention relates to the field of ship structural design technology, and discloses a horizontal connection structure between steel deck profiles and a titanium alloy hangar structure in the design of dissimilar metal connections. By setting horizontally arranged titanium plates and vertically arranged titanium web plates within the hangar structure, serving as fixing points for the connection between the hangar structure and the deck's deck plates and web plates respectively, the connection between the hangar structure and the deck is achieved in both horizontal and vertical directions, ensuring the stability and reliability of the horizontal connection between the deck and the hangar structure. Since the hull deck and superstructure decks are made of steel, and the hangar structure is made of titanium alloy, titanium-steel composite joints are installed as intermediate components between the contact surfaces of the hangar structure and various parts of the hull. These titanium-steel composite joints are formed by explosive bonding of titanium plates and steel plates. One side of the titanium-steel composite joint is welded to the deck or sill, and the other side is welded to the hangar structure, thereby achieving effective fixation of the hangar structure to the hull.

Description

Technical Field

[0001] This invention relates to the field of ship welding structure technology, specifically to a horizontal connection structure between deck steel profiles and hangar titanium alloy structure. Background Technology

[0002] Helicopter hangars on surface ships are used for parking helicopters and for related support operations. Hangars are typically located aft of the superstructure, forward of the helicopter landing platform. The hangar structure is generally made of steel, the same material as the superstructure. In the overall ship design, the hangar structure is designed for a specific helicopter model. To accommodate the deployment of new shipborne helicopters, the hangar also needs adjustment. To achieve the deployment of new helicopters within limited overall resources and minimize risks, an embedded, fixed titanium alloy hangar structure is proposed. This structure allows for the parking of new helicopters while maintaining controllable risks and minimal weight.

[0003] In the design of the hangar structure embedded in the superstructure, the horizontal connection between the titanium alloy hangar structure and the steel deck is involved. In order to ensure the fixed connection of the embedded, fixed titanium alloy hangar structure on the deck, a horizontal connection structure is urgently needed to connect the side walls of the deck and the hangar structure. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, a horizontal connection structure between the deck steel profile and the hangar titanium alloy structure is provided, solving the problem of horizontal connection between the titanium alloy hangar and the steel deck at the deck steel profile.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0006] The horizontal connection structure between the deck steel profile and the hangar titanium alloy structure is characterized in that: the deck steel profile includes a horizontally arranged deck plate and a deck web plate protruding below the deck plate; a horizontal gap is left between the end of the deck steel profile and the side wall of the hangar structure;

[0007] The horizontally welded structure includes a titanium plate horizontally arranged above the deck plate, a titanium web plate vertically arranged in the horizontal gap, a first titanium-steel composite joint welded between the titanium plate and the deck plate, and a second titanium-steel composite joint welded between the titanium web plate and the deck web plate; the first titanium-steel composite joint and the second titanium-steel composite joint are divided into two layers, each layer being made of the same material as the contacting component;

[0008] One end of the titanium plate is fixed to the hangar structure, and the other end spans the horizontal gap above the deck. The thickness of the first titanium-steel composite joint matches the vertical gap between the titanium plate and the deck plate. The upper and lower surfaces of the first titanium-steel composite joint are welded and fixed to the lower surface of the titanium plate and the upper surface of the deck plate, respectively.

[0009] The titanium web is vertically arranged within the horizontal gap. One side of the titanium web is welded to the hangar sidewall, and the other side of the titanium web is welded to a vertically arranged second titanium-steel composite joint. The other end of the second titanium-steel composite joint is welded to the end of the deck web. The width of the deck web and the titanium web matches the size of the horizontal gap.

[0010] According to the above technical solution, the top of the titanium web is welded and fixed to the bottom of the titanium plate.

[0011] According to the above technical solution, an installation gap is left between the first titanium-steel composite joint and the second titanium-steel composite joint, and sealant is injected into the installation gap.

[0012] According to the above technical solution, the hangar structure adopts a layered design. Titanium plates are installed between two adjacent hangar structures and in the horizontal gap section. The top and bottom of the titanium plates are welded to the adjacent two hangar structures respectively. A welded titanium plate is installed on the top of the top hangar structure and in the horizontal gap section.

[0013] According to the above technical solution, the deck steel profile presents a bulbous flat steel structure, and an elbow plate is provided at the bottom of the bulbous flat steel structure; the second titanium steel composite joint is connected between the bulbous flat steel structure and the titanium web, as well as between the elbow plate and the titanium web, and the length of the second titanium steel composite joint is greater than the total thickness of the bulbous flat steel structure and the elbow plate.

[0014] According to the above technical solution, the deck steel profile is composed of a vertically arranged web body and an arc-shaped plate located at the bottom of the web, and a second titanium-steel composite joint is connected between the web body and the titanium web.

[0015] The present invention has the following beneficial effects:

[0016] By installing horizontally arranged titanium plates and vertically arranged titanium web plates within the hangar structure, serving as fixing points for the connection between the hangar structure and the deck plates and deck web plates respectively, the connection between the hangar structure and the deck is achieved in both horizontal and vertical directions, ensuring the stability and reliability of the horizontal connection between the deck and the hangar structure. Furthermore, since the hull deck and superstructure decks are made of steel, while the hangar structure is made of titanium alloy, titanium-steel composite joints are installed as intermediate components between the contact surfaces of the hangar structure and various parts of the hull. These titanium-steel composite joints consist of two layers: one layer of steel and the other of titanium alloy. The steel side of the titanium-steel composite joint is welded to the deck or sill, while the titanium alloy side is welded to the hangar structure, thus achieving effective fixation of the hangar structure to the hull.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Reference Figures 1-4 As shown, the present invention provides a horizontal connection structure between the deck steel profile and the hangar titanium alloy structure.

[0024] Example 1

[0025] The deck steel profile includes a horizontally arranged deck plate 1 and a deck web plate 2 protruding below the deck plate; a horizontal gap is left between the end of the deck steel profile and the side wall 3 of the hangar structure.

[0026] The horizontally welded structure includes a titanium plate 4 horizontally arranged above the deck plate, a titanium web 5 vertically arranged in the horizontal gap, a first titanium-steel composite joint 6 welded between the titanium plate and the deck plate, and a second titanium-steel composite joint 7 welded between the titanium web and the deck web; the first titanium-steel composite joint and the second titanium-steel composite joint are divided into two layers, each layer being made of the same material as the contacting components; the first titanium-steel composite joint and the second titanium-steel composite joint specifically refer to a titanium-steel composite structure in which the titanium plate and the steel plate are explosively joined together by means of an explosive process.

[0027] One end of the titanium plate is fixed to the hangar structure, and the other end spans the horizontal gap above the deck. The thickness of the first titanium-steel composite joint matches the vertical gap between the titanium plate and the deck plate. The upper and lower surfaces of the first titanium-steel composite joint are welded and fixed to the lower surface of the titanium plate and the upper surface of the deck plate, respectively.

[0028] The titanium web is vertically arranged within the horizontal gap. One side of the titanium web is welded to the hangar sidewall, and the other side of the titanium web is welded to a vertically arranged second titanium-steel composite joint. The other end of the second titanium-steel composite joint is welded to the end of the deck web. The width of the deck web and the titanium web matches the size of the horizontal gap.

[0029] In this embodiment, by setting horizontally arranged titanium plates and vertically arranged titanium web plates within the hangar structure, serving as fixing points for the connection between the hangar structure and the deck plate and deck web plate respectively, the connection between the hangar structure and the deck is achieved in both horizontal and vertical directions, ensuring the stability and reliability of the horizontal connection between the deck and the hangar structure. Furthermore, since the hull deck and superstructure decks are made of steel, while the hangar structure is made of titanium alloy, titanium-steel composite joints are installed as intermediate components between the contact surfaces of the hangar structure and various parts of the hull. These titanium-steel composite joints consist of two layers: one layer of steel and the other of titanium alloy. The steel side of the titanium-steel composite joint is welded to the deck or sill, while the titanium alloy side is welded to the hangar structure, thereby achieving effective fixation of the hangar structure to the hull.

[0030] In Example 1, preferably, in order to ensure the robustness of the horizontal welded structure, the top of the titanium web is welded and fixed to the bottom of the titanium plate.

[0031] In Example 1, preferably, in order to facilitate the welding of the first and second titanium-steel composite joints between the hangar structure and the deck, an installation gap 8 is left between the first and second titanium-steel composite joints, and sealant is injected into the installation gap.

[0032] Example 2

[0033] The structure and principle of Example 2 are similar to those of Example 1, except that a preferred hangar structure is adopted to improve the stability of the connection between the hangar structure and the steel plate.

[0034] Specifically, the hangar structure adopts a layered design, with titanium plates installed between two adjacent hangar structures at the horizontal gap section, and the top and bottom of the titanium plates welded to the adjacent two hangar structures respectively; a welded titanium plate is installed at the top of the top hangar structure at the horizontal gap section.

[0035] like Figure 1-2 As shown, in Examples 1 and 2, the deck steel profile presents a bulbous flat steel structure 2-1A, and an elbow plate 2-2A is provided at the bottom of the bulbous flat steel structure; the second titanium-steel composite joint connects the bulbous flat steel structure and the titanium web, as well as the elbow plate and the titanium web, and the length of the second titanium-steel composite joint is greater than the total thickness of the bulbous flat steel structure and the elbow plate.

[0036] like Figure 3-4 As shown, in Examples 1 and 2, the deck steel profile is composed of a vertically arranged web body 2-1B and an arc-shaped plate 2-2B located at the bottom of the web, and a second titanium-steel composite joint is connected between the web body and the titanium web.

[0037] The above are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent changes made in accordance with the claims of the present invention shall still fall within the protection scope of the present invention.
