Description

Technical Field

[0001] The utility model belongs to the technical field of shipbuilding, and in particular relates to a ceiling hanging component structure of a ship cold storage. Background Art

[0002] At present, the ceiling hanging parts of cold storages on ships, especially large cruise ships, on the market have similar technical solutions such as patent publication number CN205475956U. They mostly use stainless steel screws to directly penetrate the cold storage ceiling and fix it, and then wrap the screws with rubber and plastic cotton from the back of the ceiling. Space should be reserved in the middle of the rubber and plastic cotton and polyurethane should be injected to reduce the heat transfer between the inside and outside of the cold storage. The cold storage area on the cruise ship is relatively large, so a large number of ceiling hanging parts are required. Since the space on the back of the cold storage ceiling on the ship is often restricted by pipes and cables, workers cannot enter the back to wrap the screws with rubber and plastic cotton and inject polyurethane after the ceiling is assembled. If the upper screw is not wrapped with rubber and plastic cotton, condensation water or even ice will be generated outside the ceiling hanging point due to excessive temperature difference when the cold storage is in a low temperature state, which will cause safety hazards to the pipes and cables in the space on the back of the cold storage ceiling on the ship.

[0003] The information disclosed in the above background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as admitting or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.

DETAILED DESCRIPTION

[0017] In order to explain the technical content, purpose and effect of the utility model in detail, the following is explained in combination with the embodiments and the accompanying drawings. In the description of this embodiment, it should be understood that the terms indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing this embodiment and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the utility model.

[0018] This embodiment discloses a ship cold storage ceiling hanging structure, which is used for the ceiling installation of the ship cold storage ceiling. Figure 1 As shown, this embodiment mainly includes a cold storage ceiling 1, a hull iron outfitting 2, an upper screw rod 3, a lower screw rod 16, a T-shaped bracket 6, and an L-shaped bracket 11.

[0019] The cold storage ceiling 1 is provided with a cold storage ceiling pre-opening 17, the upper screw rod 3 and the lower screw rod 16 are respectively arranged at the upper and lower ends of the cold storage ceiling 1, and the T-shaped bracket 6 and the L-shaped bracket 11 are arranged inside the cold storage ceiling pre-opening 17. The upper end of the upper screw rod 3 is fixedly connected to the hull iron fittings 2, which are used to provide the main stress points of the suspended ceiling, the lower end of the upper screw rod 3 extends into the cold storage ceiling pre-opening 17 and is fixedly connected to the T-shaped bracket 6; the upper end of the lower screw rod 16 extends into the cold storage ceiling pre-opening 17 and is fixedly connected to the L-shaped bracket 11.

[0020] The T-shaped bracket 6 and the L-shaped bracket 11 located inside the pre-opened hole 17 of the cold storage ceiling form a clamping portion with each other. Figure 1As shown, the T-shaped bracket 6 is placed sideways, and the L-shaped bracket 11 is placed upside down. At this time, an inner angle surface of the T-shaped bracket 6 corresponds to the outer angle surface of the L-shaped bracket 11 to form an angled clamping part, and the clamping parts are used to clamp the PVC insulating sheet 7 and fix it through a locking assembly. In this embodiment, the locking assembly can be in the form of bolts and nuts, specifically including fixing bolts 5 and fixing nuts 18. The T-shaped bracket 6, the PVC insulating sheet 7, and the L-shaped bracket 11 are provided with corresponding vertical through holes. The fixing bolts 5 pass through the corresponding vertical through holes of the T-shaped bracket 6, the PVC insulating sheet 7, and the L-shaped bracket 11 and are threadedly connected with the fixing nuts 18. The bolts and nuts are vertically locked to tighten the upper and lower brackets to clamp the PVC insulating sheet 7.

[0021] The middle of the pre-opening 17 of the cold storage ceiling is injected with polyurethane foam 15 for filling and sealing. The two ends of the pre-opening 17 of the cold storage ceiling are respectively provided with an upper cover plate 14 and a lower cover plate 13. The upper screw 3 and the lower screw 16 are respectively provided with a locking nut 4 and a lower locking nut 12. The upper locking nut 4 and the lower locking nut 12 apply force to the upper cover plate 14 and the lower cover plate 13 to clamp the two ends of the pre-opening 17 of the cold storage ceiling by rotating.

[0022] As a preferred technical solution of this embodiment, in order to enhance the insulation performance, the fixing bolt 5 passing through the T-shaped bracket 6, the PVC insulating sheet 7, and the L-shaped bracket 11 is also sleeved with a PVC insulating sleeve 10. A PVC insulating gasket 9 is also provided between the fixing bolt 5 and the T-shaped bracket 6.

[0023] The working principle of this embodiment is:

[0024] The traditional large cruise ship cold storage ceiling generates condensation water or even ice outside the ceiling hanging point due to excessive temperature difference when the cold storage is in a low temperature state, which poses a safety hazard to the pipes and cables in the back space of the cold storage ceiling on the ship. Therefore, the back construction usually requires the screw to be wrapped with rubber and plastic cotton, but because the back space of the ceiling is limited by pipes and cables, it is difficult to carry out the rubber and plastic cotton wrapping work. In this embodiment, a PVC insulating gasket is added at the middle connection position to isolate the pad transfer between the outside and inside of the cold storage. Heat is conducted to the inside of the cold storage along the hull iron outfitting 2 and the upper screw 3. When the heat reaches the customized L-shaped bracket 11, the insulation system composed of PVC insulating sheet 7, PVC insulating gasket 9 and PVC insulating sleeve 10 will block the pad conduction, thereby preventing the outside of the ceiling hanging point from generating condensation water or even ice due to excessive temperature difference when the cold storage is in a low temperature state. In addition, the hanging part cancels the rubber and plastic cotton wrapping procedure on the back, reduces the occupied space, and has the characteristics of convenient on-site construction, so the purpose of this embodiment is achieved.

[0025] During the overall installation, first weld the upper screw rod 3 to the hull iron outfitting 2, then pre-assemble the cold storage ceiling 1, determine the position of the hanging parts and open a cold storage ceiling pre-opening hole 17 with a diameter of about 50mm on the cold storage ceiling 1, adjust and determine the ceiling height, and then install the upper locking nut 4 and the upper cover plate 14; weld the customized T-shaped bracket 6 to the upper screw rod 3, and weld the lower screw rod 16 to the customized L-shaped bracket 11; tightly connect the T-shaped bracket 6 and the L-shaped bracket 11 through accessories such as fixing bolts 5, fixing nuts 18, PVC insulation sheets 7, PVC insulation gaskets 9, gaskets 8 and PVC insulation sleeves 10; formally install the cold storage ceiling and let the hanging parts pass through the position of the pre-opening hole 17 of the cold storage ceiling. The cold storage ceiling 1 is temporarily fixed by the tooling rack, and the space around the hanging parts is filled with polyurethane foam 15; install the lower cover plate 13, gasket 8 and round head lower locking nut 12.

[0026] Although the present invention has been described in detail above with specific implementation methods, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention are within the scope of protection claimed by the present invention.
