BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a heat insulation method in a cargo ship of a freezing ship, and more specifically, in a multi-layered structure partitioned into a plurality of levels by a deck, a hull comprising a plurality of decks branched laterally from the inner side of a ship-side outer wall. The present invention relates to a thermal insulation method for spraying inside a ship that forms a continuous branch heat insulation surface from the inside of the outer deck of the ship side to the lower side of the exposed deck deck and the middle deck to the structure to enable complete insulation for each level.
[0002]
[Prior art]
In the conventional thermal insulation method for freight vessels of frozen ships, the heat insulation structure inside the ship side outer wall, the horizontal partition wall inside the ship and the bottom of the heat insulation deck is made of glass wool or foamed polyurethane molded stiffeners. Cut into predetermined dimensions between (frames), stack and spread multiple sheets, and provide vertical and horizontal vertical wooden joists through bolts welded to the surface of the stiffener face. It is known that a glass wool or polyurethane foam molded article is inserted between them and nailing with a wooden plywood to form a lining board, and a protective sparring is provided thereon.
[0003]
In the conventional method described above, there are problems in that the work is complicated, man-hours are required, and a large amount of heat insulating material is used.
Further, since the molded glass wool or foamed polyurethane is cut and fixed to the stiffener interval, a gap is formed at the joint of the laminated heat insulating material, and there is a problem of lowering the heat insulating effect.
Furthermore, there has been a problem that intrusion heat is transmitted from the ship side outer wall, the upper deck, the horizontally placed bulkhead, etc. through the stiffeners of the hull member and the wooden plywood mounting bolts to raise the temperature inside the ship.
[0004]
On the other hand, a large refrigerated cargo ship is composed of a plurality of hierarchies. For example, in the case of a multi-tier structure partitioned by a plurality of deck decks, each tier may be placed in a separate cooling mode. Therefore, it is necessary to form a heat insulation space that is thermally isolated.

It is intended to establish the airtightness and thermal insulation of another ship. Therefore, heat insulation mainly composed of glass wool, maintenance of the filling surface of the glass wool by spraying of foamed resin, and thermal insulation of the exposed hull member can be achieved. This enables time and low cost construction.
[0006]
The above holding structure is made by a bolt and a wood root supported by the bolt on the inner side of the ship side outer wall, and a light groove supported together with the bolt and the bolt on each lower side of the exposed deck deck and the middle deck deck.
