Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulation method for a cargo hold.

[0002]

2. Description of the Related Art For example, the freezer hold is
Conventionally, it has been required to have a wall structure having high heat insulation properties. The heat insulation wall has conventionally been a plate material for forming a room and a component of a cargo hold (a deck for floors and ceilings, a side skin or partition for side walls).
It was formed by filling glass wool, urethane foam, etc. between However, in this method, since the glass wool is installed with a thickness enough to fill the beams and girders protruding from the deck, the thickness of the glass wool varies depending on the location. Further, since the side wall is formed by providing a joist on a frame projecting from the hull to the inside of the ship and fixing a plate material such as a plywood plate to the frame, the amount of heat conduction from the outside of the ship through the frame was large. As a result of these, it is difficult to accurately design the heat insulation because there are large variations due to the location of heat insulation.
To obtain sufficient heat insulation, there was a problem of having to perform excessive heat insulation work. In addition, due to the difficulty of this heat insulation design, proper construction required high technical skills and experience. Further, since it is necessary to install a large amount of glass wool, there is a problem that the construction requires a lot of time and labor, and the working environment tends to deteriorate.

[0003]

SUMMARY OF THE INVENTION The present invention solves the conventional problems described above, enables easy and accurate heat insulation design, enables necessary and sufficient heat insulation work, and reduces the time and labor required for the work. The purpose is to provide a heat insulation method that is reduced and has a good working environment.

[0004]

The above-mentioned object of the present invention is a method of heat-insulating a cargo hold partitioned into a plurality of layers by a deck, and a ceiling is formed by suspending and fixing a heat insulating panel below the deck. However, inside the side wall of the hull, a heat insulation panel is vertically installed and fixed to a frame or a deck along the side wall to form a side wall, thereby forming a heat insulation chamber. It is achieved by the heat insulation method.

In the panel-type heat insulation method for a hold according to the present invention, a heat insulating panel is hung and fixed on the lower side of the deck to form a heat insulating ceiling, and inside the side wall of the hull, a frame or deck along the side wall is formed. On the other hand, since the heat insulation panel is vertically installed and fixed in the vertical direction to form the side wall to form the heat insulation chamber, the heat insulation panel has a uniform thickness regardless of the presence of beams or girders protruding from the deck. Is obtained. Further, since the side wall is provided in the vertical direction even on the inclined ship side, it is possible to stably store the load, and a vertical wall forming member (a load collapse prevention device) which is separate from the inclined surface as in the conventional case. Need not be fixed. Further, since the vertical wall is independently provided with respect to the outer shell of the ship, heat transfer from the ship can be prevented. In this way, the uniform thickness of the heat insulation wall and the excellent heat insulation make it possible to accurately grasp the heat insulation characteristics of the entire heat insulation chamber, and as a result, the heat insulation design of the cargo hold can be performed easily and accurately. The necessary and sufficient heat insulation can be done. Moreover, since most of the construction can be performed by installing the panel, the construction is simple and quick, and there is no deterioration of the working environment such as when glass wool is frequently used.

Further, since there is a space for installing the panel between the heat shield panel and the deck of the hull or the ship side,
It is possible to construct electric wires and various pipes using this space. In particular, it is advantageous that the heat insulating panel can be installed before it is attached to the deck or the ship side.
