The present invention proposes a PCF board installation structure, including floor slab, upper wall body, lower wall body, lower PCF board, outer back panel, inner back panel, fixing screw, nut, upper PCF board, thread hole, adjusting screw; fixing Screws include outside screws, inside board screws, inside walls and inside screws. The advantages of the present invention: there is no need to construct L-shaped angle irons in the shear wall reinforcement, which improves the construction efficiency; the U-shaped back corrugation can adjust the verticality and positioning of the PCF board, and at the same time play the role of temporary fixation, before the formwork back corrugated reinforcement It effectively plays the role of positioning and fixing; on-site construction is convenient, avoiding possible collisions during hoisting of special connectors, and hidden dangers of water leakage caused by later sealing screw holes, and the screw rods at both ends can be used in turnover. On the premise of ensuring the safety of the connection, it is as convenient as possible to facilitate the hidden dangers of on-site construction and later maintenance.
