(See FIG. 3) (B) shows the structure of the ramen frame in which the wall slab (A) is to be built, and the joining hardware (5) is attached to the columns (3) and beams (4) constituting the same structure. Has been established. In the figure, (6) is an anchor bar of the metal fitting (5) (see FIG. 4). Therefore, the precast concrete wall slab (A) is built between the column (3) and the beam (4). And the above-mentioned hook-shaped reinforcing bar (2) is welded to the metal fitting (5) for joining the pillar (3) and the beam (4).
After joining by other means, the gap between the columns (3) and (4) and the precast concrete wall slab (A) is filled with mortar or concrete (7) to form a precast concrete earthquake-resistant wall. To construct.
