JUNCTION STRUCTURE OF HEAT INSULATION PANEL FOR ARCHITECTURAL STRUCTURE

PROBLEM TO BE SOLVED: To join heat insulation panels at upper and lower stages and to sharply improve junction workability of a plurality of heat insulation panels even when a position of a joint for joining the heat insulation panels at the upper and lower stages is changed by inverting the joint in any of a vertical direction or a horizontal direction to the heat insulation panels in a heat insulation form for construction which is formed by sequentially building the plurality of heat insulation panels in a vertical direction via the joint.SOLUTION: A joint J for joining heat insulation panels Pu, Pd at upper and lower stages is formed in a cross shape of a transverse section of: a horizontal part 10; upper and lower vertical parts 11, 12 to be extended upward and downward at right angles from the center of a width direction of the horizontal part 10, in which the horizontal part 10 is sandwiched between junction surfaces 3, 4 of the heat insulation panels Pu, Pd, and the upper and lower vertical parts 11, 12 are inserted into and joined to lower part and upper surface insertion grooves 6, 5 formed at the center of thickness directions of the junction surfaces 3, 4, respectively.
