[0002] In terms of the technical indicators for the construction of large cruise ships, the perfection of the vibration and noise reduction measures of the actual ship is very important, especially in the cabins and public areas with huge passenger flow, which have higher requirements for performance indicators such as vibration absorption, ball rebound, friction coefficient, rolling load and impact resistance. In order to isolate and suppress the transmission path of vibration and noise, the deck and bulkhead of the cruise ship need to be treated for vibration and noise reduction.

[0003] In the existing shipbuilding technology, the method of installing insulating rock wool boards on bulkheads and decks is usually used to reduce vibration and noise. However, for large cruise ships and other ship products with strict noise control, the single use of traditional insulating rock wool boards can no longer meet the noise control requirements. Summary of the invention

[0004] In view of this, the purpose of the present application is to provide a damping wall panel for ships and an installation method thereof, so as to solve the problem of how to meet the vibration and noise reduction requirements of the deck and bulkhead of the ship.

[0010] According to a second aspect of the present invention, a method for installing a damping wall panel for a ship is provided, wherein the damping wall panel for a ship is the damping wall panel for a ship as described above, and the method for installing the damping wall panel for a ship comprises: inspecting a bulkhead or a deck of a ship; prefabricating the metal plate layer; laying the damping material layer on the bulkhead or the deck of the ship; and installing the metal plate layer on the damping material layer.

[0011] Preferably, inspecting the bulkhead or deck of the ship includes: inspecting whether the surface of the bulkhead or deck is contaminated, rusted, or significantly deformed; if construction is required on the bulkhead, performing stud welding, and the stud welding includes: measuring the area size of the bulkhead; welding the studs at preset intervals;

In addition, although the examples described herein have various configurations, other configurations are possible as will be apparent after understanding the disclosure of the present application.

[0033] like Figures 1 to 4 As shown, according to a first aspect of the present invention, a damping wall panel for a ship is provided. The damping wall panel for a ship comprises a damping material layer 2 and a metal plate layer 1 .

[0034] In the following description, reference will be made to Figures 1 to 4 The specific structure of the above components of the damping wall plate for ships and the connection relationship of the above components are described in detail.

[0035] like Figures 1 to 4As shown, in an embodiment, the first side of the damping material layer 2 can be installed on the bulkhead 4 or deck (not shown) of the ship, and the metal plate layer 1 can be installed on the second side of the damping material layer 2 to absorb noise and isolate vibration. The insulating rock wool board is then installed on the outside of the metal plate layer 1 to form a composite sound insulation system, which can greatly suppress the transmission of noise. When the damping wall panel for the ship is installed on the bulkhead 4, it can play a role in reducing vibration and noise in the horizontal direction; and when the damping wall panel for the ship is installed on the deck, it can play a role in reducing vibration and noise in the vertical direction, thereby meeting the vibration and noise reduction requirements of the deck and bulkhead 4 of the ship.

[0036] Preferably, Figures 1 to 4 As shown, in the embodiment, the metal plate layer 1 can be a galvanized aluminum alloy plate to improve the overall strength of the damping wall plate for the ship, and can play the role of vibration reduction and noise reduction together with the damping material layer 2. Since the weight of aluminum alloy material is light, the use of galvanized aluminum alloy plate can effectively reduce the overall weight of the damping wall plate for the ship. In order to make the damping wall plate for the ship cover the entire bulkhead 4 and deck as much as possible, the size of the metal plate layer 1 can be standardized and customized, and the standard size can be: 400mm×400mm, and the thickness can be 2mm.

[0037] Preferably, the damping material layer 2 can be a viscoelastic damping material (which can be a viscoelastic damping material currently available on the market for vibration reduction and noise reduction), which can be bonded and fixed to the bulkhead 4 or deck of the ship, and can fix the metal plate layer 1. At the same time, the viscoelastic damping material can play a role in vibration reduction and noise reduction.

[0038] Further, preferably, in an embodiment, the viscoelastic damping material may be an artificially prepared two-component chemical material. The viscoelastic damping material may include a first component and a second component. The first component may be a polyol compound (such as a polyether polyol). The density of the polyol compound may be about 1.3 kg / L, and the color may be red, which is used to reduce vibration and noise. The second component may be an isocyanate derivative (such as a diisocyanate), and the density of the isocyanate derivative may be about 1.2 kg / L, and the color may be brown, which is used to thicken and promote curing during the preparation process. The mixing ratio of the first component to the second component may be 6:1, and the density of the viscoelastic damping material formed after mixing may be about 1.3 kg / L, in a liquid state, brick red in color, and without obvious irritating odor. When prepared in this way, the viscoelastic damping material has a good effect of absorbing noise and isolating vibration and has no shrinkage after curing. In addition, since the viscoelastic damping material does not use water as a solvent, it will not cause rust on the steel deck. Furthermore, since the viscoelastic damping material has a certain viscosity, it is easy to be laid on the steel during construction.

[0039] Preferably, Figure 1 , Figure 3 and Figure 4 As shown, in an embodiment, when the damping wall panel for a ship is installed in an area where severe noise is generated, an insulating rock wool board (not shown) can also be installed on the outer side of the damping wall panel for a ship to form a composite sound insulation system. Specifically, the insulating rock wool board can be installed on the side of the metal plate layer 1 away from the damping material layer 2. The side of the metal plate layer 1 away from the damping material layer 2 can be fixed with a plurality of rivets 3 (specifically, insulating rivets) by welding. The rivets 3 can be formed into a strip shape and bent in a direction close to the metal plate layer 1 to fix the insulating rock wool board.

[0040] Preferably, Figure 4 As shown, in the embodiment, the number of the studs 3 can be four, and the four studs 3 can be arranged at intervals along the circumferential direction, that is, with the center of the metal plate layer 1 as the center of the circle, the angle between two adjacent studs 3 is 90°. The metal plate layer 1 can be a square plate, and the four studs 3 can be arranged on the diagonal of the metal plate layer 1. When installing the insulating rock wool board, the studs 3 can be embedded in the insulating rock wool board, and then the insulating rock wool board is fixed to the damping wall panel for the ship.

[0041] Preferably, Figure 1 , Figure 3 and Figure 4 As shown, in the embodiment, since the damping material layer 2 is made of a viscous viscoelastic damping material, after the viscoelastic damping material is cured, the metal plate layer 1 can be attached to the damping material layer 2 without the need to be fixed again with bolts. However, when the damping wall panel for a ship is installed on the bulkhead 4, in order to ensure that the metal plate layer 1 will not fall off due to gravity during the curing stage of the viscoelastic damping material, and to provide the damping wall panel for a ship with a certain degree of ability to resist the vibration of the bulkhead 4, the metal plate layer 1 can be fixed to the bulkhead 4 by means of studs 5 and gaskets 6.

[0042] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, in an embodiment, a circular opening may be provided in the center of the metal plate layer 1. The damping wall panel for a ship may also include a stud 5 and a gasket 6. The stud 5 may be first fixed to the bulkhead 4 of the ship by butt welding, and then the stud 5 may be passed through the opening of the metal plate layer 1. An external thread is formed on the surface of the stud 5, and the gasket 6 may be threadedly connected to the stud 5. Since the diameter of the gasket 6 is larger than the diameter of the opening, when the gasket 6 is screwed to fit tightly against the metal plate layer 1, the metal plate layer 1 will be pressed against the damping material layer 2, thereby fixing the metal plate layer 1.

[0043] In addition, according to a second aspect of the present invention, a method for installing a damping wall panel for a ship is provided, wherein the damping wall panel for a ship can be the damping wall panel for a ship as described above. The method for installing the damping wall panel for a ship can include inspecting a bulkhead 4 or a deck of a ship; prefabricating the metal plate layer 1; laying the damping material layer 2 on the bulkhead 4 or the deck of the ship; and installing the metal plate layer 1 on the damping material layer 2.

[0044] Specifically, in an embodiment, the inspection of the bulkhead 4 or deck of the ship may include inspecting whether the surface of the bulkhead 4 or deck is contaminated, rusted, and significantly deformed. If construction is required on the bulkhead 4, stud welding may be performed first (if construction is performed on the deck, stud welding is not required). The stud welding work includes first measuring the area size of the bulkhead 4, then welding the studs 5 at preset intervals (which may be 405mm×405mm in the horizontal and vertical directions), and finally removing the weld nodules dripping on the bulkhead 4, grinding the roots of the studs 5, and repairing the epoxy primer.

[0045] Preferably, in an embodiment, prefabrication of the metal sheet layer 1 may include shearing the metal sheet layer 1 according to the structure of the bulkhead 4 or the deck; and then pre-installing the sheared metal sheet layer 1 on the bulkhead 4 or the deck for visual inspection. Since other structures (such as brackets, penetrations, etc.) may also be arranged on the deck and bulkhead 4, in order to ensure that more than 90% of the area of ​​the deck or bulkhead 4 is covered with the metal sheet layer 1, it is necessary to perform appropriate shearing treatment on the metal sheet layer 1 installed at the structure position according to the shape of the root of the structure. Thereafter, the metal sheet layer 1 may be pre-installed on the deck or bulkhead 4 through the studs 5 and the gaskets 6 for visual inspection. If there is no need to shear the thin plate again, the metal sheet layer 1 may be removed for subsequent operations.

[0046] Preferably, in an embodiment, laying the damping material layer 2 on the bulkhead 4 or deck of the ship may include checking the temperature and ambient humidity of the bulkhead 4 or the deck to ensure that the construction is carried out in an environment where the temperature is lower than 35°C and the humidity is lower than 80%. The surface of the bulkhead 4 or the deck is cleaned before laying the viscoelastic damping material. After mixing the viscoelastic damping material according to a preset ratio (i.e., the mixing ratio of the first component to the second component is 6:1) for 15 minutes, it is evenly laid on the surface of the bulkhead 4 or the deck with a scraper.

[0047] Preferably, in an embodiment, installing the metal sheet layer 1 on the damping material layer 2 may include pasting and installing the metal sheet layer 1 on the surface of the damping material layer 2 according to the arrangement during pre-installation. Since the viscoelastic damping material is sticky, the metal sheet layer 1 will be bonded to the surface of the damping material layer 2 after curing. If the construction is on the bulkhead 4, it is necessary to install the gasket 6 on the stud 5 immediately after the metal sheet layer 1 and the damping material layer 2 are attached, and press the gasket 6 on the surface of the metal sheet layer 1 to prevent the metal sheet layer 1 from falling off due to gravity. If the construction is on the deck, it is not necessary to drill holes in the metal sheet layer 1 and install the stud 5 and gasket 6.

[0048] During use, the ship's damping wall panel can be installed on the bulkhead 4 and the deck. It has a simple and strong structure, and combines the rivets 3 with the metal plate layer 1, thereby avoiding damage to the damping material layer 2 by the heat of the rivet 3 welding during construction. The metal plate layer 1 of the ship's damping wall panel adopts a galvanized aluminum alloy plate. The aluminum alloy has the advantages of high strength and light weight, which can effectively reduce the weight of the ship's damping wall panel. The galvanizing treatment makes the metal plate layer 1 corrosion-resistant and not easy to rust, and has a longer service life, which is advantageous for large cruise ships with strict weight control.

[0049] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them. The protection scope of the present application is not limited thereto. Although the present application is described in detail with reference to the above-described embodiments, ordinary technicians in the field should understand that any technician familiar with the technical field can still modify the technical solutions recorded in the above-described embodiments within the technical scope disclosed in the present application, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
