Abstract

PURPOSE:To raise the efficiency of production of heat-insulating panels by a method in which an injection tube is pierced through holes provided almost linearly from sides in a frame member and a reinforcing member, an expandible material is injected into the internal space and then into near-side corners in such a way as to inject the expandible material uniformly. CONSTITUTION:Holes 8 and 9 are drilled almost linearly in the sides of a frame member 1 and a reinforcing member 2, and then in injection tube 5 is pierced through the holes 8 and 9. In this case, a guide tube is provided in advance for convenience in order to give support to the insertion of the injection tube. Then, an expandible filler is injected first into the internal space S1 from an injection nozzle 7 until a given amount of the expandible filler is packed, the injection tube 5 is pulled back, the injection nozzle 7 is positioned in an internal space S2, and then a given amount of the expandible filler is injected into the space S2. In such a manner, the filler is injected orderly into spaces S3, S4, S5...S9 to obtain a heat-insulating panel filled with a given amount of the expandible filler.
