Regularly decide people and control individual layer engineering time, the assembled interior decoration inserts in advance, can prolong single process operating time, can reduce the operation number simultaneously, is favorable to improving workman's operation proficiency, improves construction quality.

The assembled main structure, the secondary structure, the aluminum alloy outer window and the outer wall coating adopt laminar flow water, and the assembled internal decoration adopts sleeve flow water; the outer decoration (including balcony and garden), indoor assembled interior decoration, public staircase (including people and goods elevator) are not crossed in the plane, and the self-flowing water is not crossed; each laminar flow section is in the sequence of exterior decoration (including balconies and garden entering the home) → interior fitting → public stairwells (including the home where the people and goods elevator is located).
Inserting nodes for N-21 penetration construction:
1) when the structure is constructed to 4 layers, the aluminum alloy template quick-release system, the attached lifting scaffold system and the construction external elevator are put into use, the construction external elevator is immediately erected along with the construction progress of the secondary structure, and the height of each time is always separated from the bottom end of the attached lifting scaffold by one layer;
2) starting inserting assembly type interior decoration construction when the structure is constructed to 4 layers;
3) when each layer of structure is constructed, a secondary structure and a smoke duct of the lower three layers are constructed, and the secondary structure masonry and the smoke duct are hoisted in advance by utilizing a tower crane before the construction laminated plywood is hoisted.
