The construction scheme of the prior art is shown in Figure 1 and Figure 1 Shown in 2: The rectangular shear wall steel column 1 is fixed with a stiffening plate 2 extending to the outside. The support structure adopts the form of template 3 + secondary beam 4 + main beam 5 + pair of tension screws 6, and the template 6 is fixed on the stiffener. On the outside of the plate 2 and the outside of the formwork 6, several secondary beams 4 are fixed, and several main beams 5 are fixed on the outside of the secondary beams 4.
