The invention discloses an
assembly type building stair mold, and relates to the technical field of stair molds, the
assembly type building stair mold comprises a mold mechanism, the side face of the mold mechanism is provided with a transverse
steel bar limiting mechanism, and the transverse
steel bar limiting mechanism is used for limiting and fixing transverse steel bars in a prefabricated stair. According to the longitudinal reinforcement limiting mechanism, the height of a clamping head is accurately adjusted through a third mounting bolt, the clamping head can be flexibly selected according to the
diameter of a longitudinal reinforcement, the mounting height and position of the longitudinal reinforcement can be accurately controlled, the overall positioning accuracy of a reinforcement framework is guaranteed, and then the
mechanical property of the prefabricated stair is improved; the sleeve plays a role in protecting the end, inserted into the mold mechanism, of the third mounting bolt, it is avoided that concrete adhesion affects bolt disassembly, meanwhile, due to the detachable design of the third mounting bolt and the
modular structure of the
steel bar limiting mechanism, the demolding difficulty is lowered, damage to
stairs after a component is formed is reduced, and the demolding efficiency and the finished product quality are improved.
