10. A fabricated staircase production method using the ribbed thin-shelled staircase moving mold system according to any one of claims 1 to 9, characterized in that the fabricated staircase production method comprises the steps of:

a. driving the second die main body to approach the first die main body to a mold clamping state by a first telescopic driving device, enclosing the first die main body, the second die main body and the rib mold into a concrete pouring space, and fixing the first die main body and the second die main body to each other;

b. installing a hole-opening tool for forming a reinforcing rib of the prefabricated staircase and a lifting hole on the tread;

c. applying a concrete release agent to respective working surfaces of the first die body, the second die body and the rib die;

d. pouring concrete materials in a pouring space defined by the first die main body, the second die main body and the rib dies, uniformly vibrating, and then trowelling the upper surface of the poured concrete materials after the pouring space is filled;

e. waiting for the concreted concrete material to be hardened to the demolding strength, forming the prefabricated staircase with the reinforcing rib, wherein hoisting holes are formed in the reinforcing rib and the tread of the prefabricated staircase;

f. removing the hole opening tool, fixing the formed prefabricated staircase with the reinforcing ribs and the second die main body together, enabling the first telescopic driving device to retract, demolding the prefabricated staircase and the first die main body, stopping after the first telescopic driving device retracts to a preset distance, and locking the first telescopic driving device;

g. the prefabricated staircase and the second mould main body are released from being fixed, and corresponding to the above, the bolt for connecting the prefabricated staircase and the second mould main body can be specifically removed, so that the second telescopic driving device retracts, and the rib mould and the prefabricated staircase are demoulded;

h. controlling a third telescopic driving device to extend, penetrating through the second mould main body and pushing the prefabricated staircase, so that the prefabricated staircase is separated from the second mould main body;

i. and a lifting appliance is arranged aiming at lifting holes formed on the reinforcing ribs of the prefabricated staircase, and the prefabricated staircase is lifted away.
