It is laterally lifted on the predetermined position of prefabricated middle shear wall, is overlapped on full precast floor slab bottom on angle steel, and make overhanging rectangle muscle
The transverse steel interlaced arrangement exposed with full precast floor slab；Then channel steel is passed through into overhanging rectangle muscle and full precast floor slab is exposed
The rectangle that transverse steel is formed；Junction between prefabricated middle shear wall and full precast floor slab pours into grouting material, to grouting material
After reaching expected intensity, the connection between prefabricated middle shear wall and full precast floor slab is completed.
