Description

Technical Field

[0001] This utility model belongs to the field of ceiling technology and relates to a marine ceiling with an inspection door structure. Background Technology

[0002] With the development of the shipbuilding industry, the requirements for ships in all aspects are becoming increasingly higher. For example, in terms of sound insulation, due to the special structure of ships, there are inspection doors on the ceiling of the interior space. The inspection doors are usually made of single-panel structure, which has a very poor sound insulation effect. Moreover, in the current technology, the inspection doors are usually installed later, which requires drilling holes in the ceiling on site, and then installing the door frame and other components on the ceiling. During the construction process, the flatness of the ceiling and the sealing between the inspection door and the ceiling cannot be guaranteed. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a prefabricated marine ceiling with an inspection door structure.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0005] A marine ceiling with an inspection door structure includes:

[0006] The plate has an installation hole at one end, and a mounting reinforcement frame is provided inside the plate outside the installation hole; the inner sidewall of the mounting reinforcement frame has evenly distributed connection holes.

[0007] The door frame is fixedly installed inside the mounting reinforcement frame using connectors. The connectors can mate with the connection holes. A sound-absorbing washer is provided between the door frame and the mounting reinforcement frame. A connecting plate is provided on one side of the door frame, and a baffle is provided on the other side of the door frame.

[0008] The door panel is connected to the door frame by hinges and can cooperate with a baffle; the inner surface of the baffle is provided with a sound-absorbing strip that can cooperate with the door panel; the interior of the door panel is filled with sound-insulating cotton.

[0009] Preferably, the board has a composite structure, with the middle layer made of fireproof cotton.

[0010] Preferably, the interior of the mounting reinforcement frame is filled with sound-insulating cotton.

[0011] Preferably, the outer side of the connecting panel is provided with a bending strip that can cooperate with the sheet material.

[0012] Preferably, the mounting reinforcement frame is fixedly connected to the plate.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] The door frame and door panel of this utility model are directly assembled with the board material, eliminating the need for additional drilling during ceiling installation and improving work efficiency. By filling the door panel and the installation reinforcement frame with sound insulation cotton, and in conjunction with sound-absorbing washers and sound-absorbing strips, multiple sound absorptions are formed to reduce noise and improve the comfort of the ship's interior space.

[0019] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] This embodiment proposes a marine ceiling with an inspection door structure, including a panel 1, a door frame 6, and a door panel 9. The panel 1 serves as the main body of the ceiling, and the door panel 9 is installed on the panel 1 through the door frame 6.

[0021] like Figures 1-2 As shown, a mounting hole 2 is provided at one end of the plate 1, and a mounting reinforcement frame 3 is provided inside the plate 1 outside the mounting hole 2. The mounting reinforcement frame 3 is used to improve the connection strength of the plate 1.

[0022] The inner wall of the mounting reinforcement frame 3 has evenly distributed connection holes 4;

[0023] The door frame 6 is fixedly installed inside the mounting reinforcement frame 3 using a connector 15 that can mate with the connection hole 4. A sound-absorbing washer 14 is provided between the door frame 6 and the mounting reinforcement frame 3. The sound-absorbing washer 14 is made of rubber material and can reduce the friction noise between the door frame 6 and the mounting reinforcement frame 3.

[0024] One side of the door frame 6 is provided with a connecting plate 7, which makes the installation of the door frame 6 aesthetically pleasing; the other side of the door frame 6 is provided with a baffle 8.

[0025] The door panel 9 is connected to the door frame 6 by hinge 10. The door panel 9 can cooperate with the baffle 8. The baffle 8 ensures that the door panel 9 will not move out of place and can seal the door frame 6.

[0026] The inner surface of the baffle 8 is provided with a sound-absorbing strip 11 that can cooperate with the door panel 9. The sound-absorbing strip 11 prevents friction noise between the door panel 9 and the baffle 8. The interior of the door panel 9 is filled with sound-absorbing cotton, which gives the door panel 9 good sound insulation performance.

[0027] Furthermore, the board 1 is a multi-layer board, with the middle layer made of fireproof cotton, and the reinforcing installation frame 3 is clamped between the two layers of the board 1.

[0028] Furthermore, the interior of the mounting reinforcement frame 3 is filled with sound-insulating cotton, which further weakens the noise transmitted from the access door.

[0029] Furthermore, the outer side of the connecting panel 7 is provided with a bending strip 13 that can cooperate with the plate 1. The bending strip 13 can abut against the lower surface of the plate 1 without leaving gaps, providing a certain sealing effect while also appearing more aesthetically pleasing.

[0030] Furthermore, the mounting reinforcement frame 3 and the plate 1 are fixed together by adhesive bonding, which makes the connection between the mounting reinforcement frame 3 and the plate 1 quick and firm.

[0031] Working principle: When in use, the plate 1 can be directly fixed to the keel on the top of the cabin by bolts. By pre-installing the inspection door on the plate 1, no additional holes need to be drilled during assembly, ensuring flatness and sealing of the inspection door. The door panel 9 and the installation reinforcement frame 3 are filled with sound insulation cotton, which makes the overall sound insulation effect of the inspection door better.

[0032] It is understood that the above embodiments are merely exemplary models used to illustrate the principles of this utility model, and this utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
