Method for manufacturing heat-insulating member and device therefor

A method for manufacturing a heat-insulating member including a shell filled with a foamed heat-insulating material, which comprises the steps of:

• providing first and second jigs, each including a jig body substantially formed of a heat-insulating material and having its inside contour substantially complementary to the outside shape of said shell, and a reinforcing frame arranged at the periphery of said jig body for reinforcing said jig body;
• laying said shell which has not yet been filled with the heat-insulating material and is hollow, on the jig body of said first jig;
• putting said second jig on said shell, thereby preventing said shell from being deformed when a foamable liquid composition is foamed within said shell in the step to follow;
• injecting the foamable liquid composition into said shell to foam said composition therein;
• and,
• removing a resultant heat-insulating member from said first and second jigs.
