[0028] Specifically, when the high-strength concrete sandwich insulation board is poured and constructed, the concrete outer layer 4 and the concrete inner layer 3 are first poured and formed at the high-strength concrete sandwich insulation board construction site, then the insulation layer 2 is inserted into the installation space reserved between the concrete outer layer 4 and the concrete inner layer 3, the screw rod 63 is rotated by rotating the rotating disc 61, the linkage rod 68 is lowered along the guide sleeve 69 after the screw rod 63 is rotated and cooperates with the screw groove 67, and the limiting rod 66 is inserted into the limiting sleeve 62 on the reinforcing net rack 5 by means of the connecting rod 64 while the linkage rod 68 is lowered, so as to realize the quick limiting installation between the insulation layer 2 and the concrete outer layer 4 and the concrete inner layer 3.
