Description

Technical Field

[0001] This utility model relates to the field of ship cabin wall panel technology, and in particular to a lightweight fire-resistant ship cabin wall panel. Background Technology

[0002] Ship bulkheads primarily serve to separate cabin spaces, provide sound insulation, heat insulation, and fire protection. Traditionally, ship bulkheads are rigidly connected, resulting in direct contact between steel plates. This increases vibration and sound transmission, leading to poor sound insulation. Furthermore, the weight of the bulkheads directly affects ship performance, including speed, fuel consumption, and overall load-bearing capacity. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a lightweight fire-resistant ship cabin wall panel, which more precisely solves the problems described above.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model proposes a lightweight fire-resistant ship cabin wall panel, including a cabin wall panel body. The cabin wall panel body includes a buffer layer. A first reinforcing layer and a second reinforcing layer are respectively connected to the upper and lower surfaces of the buffer layer. The first reinforcing layer and the buffer layer are surrounded by a wall panel shell. The buffer layer includes an elastic substrate. The elastic substrate is a plate body shaped by an "S" bend. A wrinkled buffer part is provided in the middle of the elastic substrate. Sound-absorbing plate layers are connected to both the upper and lower parts of the elastic substrate.

[0006] Furthermore, the sound-absorbing panel is a sound-absorbing foam panel, and the sound-absorbing panel has air bubbles inside, with the pore size of the air bubbles being 1-2 mm and the volume ratio of the air bubbles being greater than 35%.

[0007] Furthermore, a buffer gap of 2-3 mm is left between the two sound-absorbing panels in the buffer layer.

[0008] Furthermore, both the first reinforcing layer and the second reinforcing layer use a flat plate as a substrate, and honeycomb grooves are formed on the substrate.

[0009] Furthermore, several dovetail grooves are provided on the upper and lower surfaces of the two sound-absorbing panels in the buffer layer, and several dovetail strips are integrally formed on the bonding surfaces of the first reinforcing layer, the second reinforcing layer and the sound-absorbing panel, and the dovetail strips and dovetail grooves are engaged and locked together.

[0010] Furthermore, the wall panel shell is composed of two interlocking shells, one of which has a telescopic groove on its side and the other has a telescopic sliding edge on its side, and the telescopic sliding edge is engaged with and locked in the telescopic groove.

[0011] The beneficial effects of this utility model are:

[0012] 1. The elastic substrate in the buffer layer of this utility model is a plate body formed by bending in an "S" shape. The middle part of the elastic substrate is provided with a wrinkled buffer part, so that the buffer layer has good buffering and shock absorption performance for the vibration impact of the panel. The upper and lower parts of the elastic substrate are connected with sound-absorbing board layers. The sound-absorbing board layers are sound-absorbing foam boards. The sound-absorbing board layers have air bubbles inside. The porous structure effectively absorbs and reflects sound waves and reduces noise.

[0013] 2.

The elastic substrate 1021 is a plate body formed by bending in an "S" shape. A wrinkled buffer part 1022 is provided in the middle of the elastic substrate 1021. A buffer gap of 2-3mm is left between the two sound-absorbing board layers 1023 in the buffer layer 102, so that the buffer layer 102 has good buffering and shock absorption performance for the vibration impact of the panel.

[0022] The upper and lower parts of the elastic substrate 1021 are connected to sound-absorbing panels 1023. The sound-absorbing panels 1023 are sound-absorbing foam panels.

The telescopic sliding edge 1032 slides and engages with the telescopic groove 1031, so that the wall panel shell 103 can adapt to the deformation buffer of the buffer layer 102.

[0026] The upper and lower surfaces of the two sound-absorbing board layers 1023 in the buffer layer 102 are provided with several dovetail grooves 1024. Several dovetail strips 1013 are integrally formed on the bonding surfaces of the first reinforcing layer 101, the second reinforcing layer 1011 and the sound-absorbing board layer 1023. The dovetail strips 1013 and the dovetail grooves 1024 are engaged and locked together, so that the first reinforcing layer 101, the second reinforcing layer 1011 and the buffer layer 102 have a good structural connection, effectively preventing the layers from falling off.

[0027] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: In this utility model, both the first reinforcing layer 101 and the second reinforcing layer 1011 are provided with honeycomb grooves 1012, which makes the cabin wall panel body 1 have good lateral pressure resistance performance, while ensuring the lightweight of the cabin wall panel body 1. The first reinforcing layer 101, the second reinforcing layer 1011 and the buffer layer 102 are connected by dovetail slide strips 1013 and dovetail slide grooves 1024, which makes the first reinforcing layer 101, the second reinforcing layer 1011 and the buffer layer 102 have a good structural connection, effectively preventing the layers from peeling off.
