First, rebar (not shown) construction is performed at a predetermined place on the installation surface prior to the formwork, and the rebar construction is performed in a state in which the outer and inner insulation molds (Mo, Mi) do not exist, and the work is easy. .

Subsequently, outer side and inner side insulation molds Mo and Mi are constructed using the thermal insulation panel P, the T bar J, and the assembly tie A. As shown in FIG.

The plurality of insulation panels P and the T bars J are transported separately to the construction site.

Next, the installation procedure of the inside and outside heat insulation formwork Mi, Mo is demonstrated.

(1) As shown in Fig. 8A, the first stage (lowest stage) on the starting base B (see Fig. 1) fixed on the inner and outer mounting surfaces (concrete foundation or concrete slab). The plurality of heat insulation panels P) are horizontally sequentially arranged in the vertical direction with their longitudinal directions laterally facing each other. In the half end part which arises between the total dimension L1 of the several insulation panel P horizontally laid, and the horizontal dimension L2 of the heat insulation formwork M to be built,材) P 'is cut out, and the end material P' is transversely cut in half.

Insert the bottom half of) and connect. Since the long T bar J spans the plurality of joints 10 of the cutting material P 'and the plurality of heat insulating panels P, the joint 10 is shifted by the T bar J or the glass is formed. The joint 10 of the heat insulation panel P and the end material P 'can be firmly combined. At this time, the plurality of locking hooks 14 formed on the T bar J are embedded in the heat insulation panel P, and the bonding strength thereof is further increased. In addition, the T bar J can slide in the longitudinal direction with respect to the heat insulation panel group P (1) of a 1st step | paragraph, and the position adjustment of the longitudinal direction with respect to the said heat insulation panel group P (1) is possible.
