てもよい。[Means for Solving the Problems] In order to achieve the above object, the present invention provides a heat insulating structure for a cargo refrigerating barge of a refrigerating freighter, which is used as a face material for a stiffener of a ship side outer plate and a horizontal bulkhead. A steel support leg with a trapezoidal cross section is welded, and a hard rubber heat insulating bolt joint with a square cross section is attached to the support leg by bolts and nuts. -Shaped joist steel is formed into a flat surface by several sets of joist steel pivotally attached with bolts and nuts, and wooden joist board is fastened to the joist steel with wood screws, and urethane foam is sprayed on the outer shell of the ship. Instead of tightly plywood, wooden joists of appropriate width may be applied at appropriate intervals.
