[0023] In actual use, the operator can build the cross support frame 1 layer by layer from bottom to top on one side of the already built steel cage. After each layer of cross support frame 1 is built, the cross support frame 1 in the horizontal direction is first welded and fixed, and then the foam concrete insulation layer 2 is inserted. After the insertion is completed, the upper layer of cross support frame 1 is built and the foam concrete insulation layer 2 is inserted. At this time, the upper and lower layers of cross support frames 1 should be welded and fixed first, and then the horizontal welding should be performed. After all the construction is completed, the tension bolts are installed through the through holes 111 to tie the formwork on both sides of the steel cage, and then subsequent work such as pouring concrete is performed. After the tension bolts are removed later, the curtain wall and other exterior wall enclosures can be hung through the through holes 111.
