Fireproof fabricated wall

The fireproof fabricated wall comprises a shell, a cover plate and a water tank, a mounting cavity is inwards formed in the wall face of one side of the shell, connecting rods are mounted on the wall faces of the two sides of the mounting cavity correspondingly, and the other ends of the connecting rods extend out of the mounting cavity and are hinged to the inner side wall face of the cover plate; the water tank is installed in the installation cavity, a flow direction control valve is installed in the installation cavity, and the trigger end of the flow direction control valve is located below the connecting rod. By arranging the connecting rods and the cover plates hinged to the connecting rods, the wall can be assembled in a normal state, and when a fire occurs, the cover plates can be automatically opened and keep a certain distance from the shell, so that heat transfer to an external structure is reduced, the situation that an outer layer structure and the shell are excessively deformed and cannot be us
