Specifically, the principle of field installation is as follows:
(1) the installation is carried out on the principle that the core tube is advanced, and concrete is poured into the shear wall and the outer frame column without occupying the time of the steel structure installation procedure. Specifically, the core tube is firstly advanced, and the key process time of steel structure installation is not occupied by concrete poured in the shear wall and the outer frame column, so that rapid installation is realized.
(2) The maximum free height of the core tube steel box shear wall exceeding the horizontal floor slab is 12-18 m. Specifically, the maximum free height of the core tube steel box shear wall exceeding the horizontal floor slab is calculated according to on-site wind pressure check, and the maximum free height of the core tube steel box shear wall exceeding the horizontal floor slab is controlled to be 12-18 m.
(3) The maximum free height of the outer frame column exceeding the horizontal floor slab is 6-9 m.

Specifically, the maximum lagging layer number of concrete poured in the core tube steel box shear wall and the outer frame column is checked and calculated according to on-site wind pressure and steel structure system correction factors, and the maximum lagging layer number is controlled to be lower than 1 floor or the installation height of the lagging core tube steel box shear wall is 16-22 m, and the installation height of the lagging outer frame column is 9-14 m. That is to say, the limitation of the maximum lagging layer number of the concrete poured in the core tube steel box shear wall and the outer frame column can be that the requirement of 'being lower than the floor deck 1 layer', the requirement of 'the installation height of the lagging core tube steel box shear wall is 16-22 m, and the installation height of the lagging outer frame column is 9-14 m', and the two limitation conditions are selected.
(5) The core tube steel box shear wall, the outer frame column and the steel beam plate of each layer form a mounting ring, after one mounting ring is mounted, 2 layers of units with the height of 4 floors are mounted in advance on the core tube steel box shear wall in the next mounting ring, 1 layer of units with the height of 2 floors are mounted in advance on the outer frame column, and concrete is poured into the core tube steel box shear wall and the outer frame column and lags behind by 1 floor.
