The inner and outer base member combined formwork heat insulating panel Y is more easily bent by the grooves 33 and 34 of the heat insulating plate 30 and the gap 45 of the inner and outer base member 40. That is, as shown in the figure, when forming a concave curved surface, the groove 33 formed on the platen surface is deformed to expand, and the groove 34 formed on the surface side is deformed to narrow. The heat insulating plate 30 is easily bent, and the gap 45 between the inner and outer base members 40 is narrowed, so that the inner and outer base members 40 are easily bent. On the other hand, when the protruding curved surface is formed, the groove 33 formed on the platen surface is deformed so as to be narrowed, and the groove 34 formed on the surface side is deformed so as to be widened, whereby the heat insulating plate 30 is curved. The clearance 45 between the inner and outer base members 40 becomes wider, so that the inner and outer base members 40 are easily bent.
Thereafter, the separator S is passed through the heat insulating plate separator hole 32 and the protruding strip separator hole 33 overlapped with each other, and the foam fixing tool F is fixed to the end of the separator S, so that the heat insulating plate 30 and the inner and outer base members 40 are firmly attached. Fix and reinforce the support using foam fixtures. At this time, again, the vertical end thick material can be omitted by the ridge 41a and the like. When the formwork is completed, concrete is cast, cured and hardened, then the support is disassembled, and the nut is engaged with the end of the separator from which the foam fixture is removed, and the inner and outer base members 40 are insulated by the nut. Secure to the plate 30. Thereafter, the inner and outer base materials are fixed to the inner and outer base member 30, and the operation is completed. As in the first embodiment, when it is desired to use an inner / outer base member other than the inner / outer base member 40, the inner / outer base member 40 is removed from the heat insulating plate 30, and another inner / outer base member is placed in the vertical groove 41a, etc. It is also possible to fix the separator using a separator.
