and a sixth step: and after grouting materials and/or impervious fine stone concrete are/is solidified, reserving a gap of 20-40mm close to the waterproof side of the roof, coating and embedding waterproof paint or factice in the gap, pouring a laminated panel and a reverse edge after the laminated panel and the reverse edge reinforcing steel bar are coated, and finishing the installation of the unitized assembled reinforced concrete building main body structure.
10. The installation and construction method of the assembly-type reinforced concrete building main body structure according to claim 9, wherein: in the third step, when the partition wall adopts a large assembled reinforced concrete slab, the foundation, the buttress and the lower beam with the lower parts fixed are fixed on the foundation, the buttress and the lower beam according to the steps from the first step to the third step, the upper part of the inner partition wall enters the fourth step after being temporarily supported and fixed, and after the fourth step is completed, the upper part of the partition wall is fixed on the upper beam, the slab and the column; when the partition wall adopts the conventional light partition wall and the light interior trim integrated partition wall, the light interior trim integrated partition wall does not need secondary decoration, the weight of the single body is not large, the single body can be arranged on a beam or a simple foundation, and the single body can be manually and directly installed after the main body structure is installed without large-scale hoisting equipment.
