10. The use method of the adjustable prefabricated staircase mold is characterized by comprising the following steps:
s1, installing anti-slip strips and chamfer cushion blocks with specified thickness on one side of the step module for forming the stair tread; 2n step modules are required to be installed, wherein n is the number of the stair steps;
s2, hoisting the n stepping modules to the first supporting beam to form a first section mould, and hoisting the rest stepping modules to the second supporting beam to form a second section mould; adjusting the angle position by using a mark time corrector, locking a mark time module on the first section die by using an anti-tilting device on the die support, and locking a mark time module on the second section die by using an anti-tilting device on the movable support to prevent inclination;
s3, screwing a fixing plate on the mold support with a stepping module on a first adjacent section mold, and screwing a fixing plate on the movable support with a stepping module on a second adjacent section mold;
s4, hoisting the first bottom die and the second bottom die to enable the first bottom die and the second bottom die to be in threaded connection with the first hydraulic cylinders and the second hydraulic cylinders which are located on the two sides of the supporting column respectively; controlling the first hydraulic cylinder and the second hydraulic cylinder to ascend to a specified position;
s5, hoisting the backboard module, enabling the backboard module to be in threaded connection with the support column, hoisting the two corner modules and respectively in threaded connection with two ends of a backboard module formed by splicing the backboard module; hoisting the end part module, and respectively connecting and fixing two ends of the first section die and the second section die with the two corner modules through the end part module;
s6, the die sinking hydraulic cylinder contracts to clamp the second section mould, the second bottom mould, the back plate module, the first bottom mould and the first section mould;
s7, clamping the upper part by using an upper counter-pulling device, and locking the lower part by using a lower counter-pulling device;
s8, pouring and shaping;
s9, opening the mould, and loosening the upper counter-pulling device and the lower counter-pulling device; disassembling end modules at two ends of the second mould, extending the mould opening hydraulic cylinder, driving the second mould to open by the movable support, and taking out the stairs poured on the second bottom mould;
s10, closing the die, opening the die and contracting the hydraulic cylinder, and fixing the end modules at the two ends of the second die with the corner modules again;
and S11, opening the mould, disassembling the end modules at the two ends of the first mould, extending the mould opening hydraulic cylinder, driving the first mould and the backboard module to be opened simultaneously by the movable support, and taking out the stairs poured on the first bottom mould.
