Description

Main layer plywood of film cabin enclosure system Technical Field The invention relates to the technical field of ship and ocean engineering, in particular to a main layer plywood of a film cabin enclosure system. Background The membrane cabin enclosure system is a core safety structure of high-end equipment such as Liquefied Natural Gas (LNG) transport vessels, large liquid cargo tanks and the like, and a main layer plywood is used as a key bearing member and is mainly used for supporting a main screen wall membrane, transmitting structural stress and realizing fixation with a hull inner shell plate in a metal plate anchoring and bolting mode. In the prior art, the main screen wall film is usually in sealed connection by adopting a welding process, meanwhile, the support of the film corrugated pipeline is completed by embedding the corrugated wedge blocks into the side gaps of the plywood, and the metal plate is fixed on the surface of the plywood by a door nail or a screw connection mode so as to ensure the reliable connection between the enclosure system and the ship body structure. However, in the prior art, the heat protection top surface and the plywood are in contact with the welding part of the edge of the upper corrugated board, and the heat conduction is large during welding because the heat protection is directly in contact with the corrugated board. Disclosure of Invention The present invention has been made in view of the above-mentioned problems occurring in the prior art. In order to solve the technical problems, the invention provides a main layer plywood of a film cabin enclosure system, which comprises a metal foil, wherein the metal foil is arranged on one side of the main layer plywood, which is close to a main screen wall film, and is used for thermal protection; A placing groove for detachably mounting the metal foil is formed in one side of the main layer plywood, and the placing groove penetrates through two sides of the main layer plywood; The metal foil is not fixedly attached to the upper surface of the main layer of plywood.
