C. connecting plate (3-1-5) between beam upper plate is placed on internal ground beam slab (2), Shi Ding area (3-1- is connected between beam upper plate 19) nail is applied, is docked on ground beam slab (2) with longitudinally adjacent plate；Beam slab (2) and bottom modularization building cover board B class plates (3- on ground 2) postposition is set to add beam slab connection reinforcement plate (3-1-9) between, nail is applied in ground beam slab Shi Ding areas, using scene bottom injection Nail (5-2) will add beam slab connection reinforcement plate (3-1-9), bottom modularization building cover board B classes plate (3-2) with ground beam slab (2), postposition Lower beam connecting plate (3-1-7) connection；

D. Shi Ding areas (3-1-19) is connected between lateral plate between the beam upper plate of connecting plate (3-1-3) and applies nail, is connected with laterally adjacent plate It connects.
