[0002] Prefabricated stairs are one of the commonly used components in prefabricated buildings. They are produced in the component factory and then transported to the construction site for installation. After installation, they can be used immediately as on-site construction passages. They are convenient and fast. In the production of prefabricated stairs, handrail embedded parts can be buried in advance, and anti-slip strips, drip lines and other structures can be cast in one time through fixed mold production, reducing the secondary processing process of the on-site stairs.

[0003] After searching, the utility model patent with Chinese patent application number "202121442078.0" discloses "a prefabricated staircase and ladder beam connection device", which "includes ladder beams, prefabricated stairs, and also includes screws, bolt anchor heads, steel plates, and anchor hooks; one side of the steel plate is provided with a bolt anchor head, and the bolt anchor head is cooperatively connected with the screw, and the other side of the steel plate is provided with an anchor hook; the anchor hook is connected to the ladder beam, and the screw is connected to the prefabricated staircase. In the utility model, the prefabricated stairs are connected by welding screws on the upper part of the steel plate in the later stage, which effectively compensates for the defect that the embedded bolts are prone to displacement. By welding the bolt anchor heads on site according to the actual position of the reserved holes of the stairs, there is no need to adjust the position or embed reinforcement like traditional embedded bolts, thereby avoiding the damage to the main structure caused by re-embedding reinforcement in the later stage.

[0004] The utility model patent with Chinese patent application number "CN202322157270.0" discloses "a prefabricated staircase building structure and its assembly connection node", wherein the assembly connection node of the prefabricated staircase building structure includes a first embedded component, a second embedded component and a connector; the first embedded component is embedded in the shear wall, and one end is exposed outside the shear wall; the second embedded component is embedded in the prefabricated staircase, and one end is exposed outside the prefabricated staircase; the connector is an integral component, and the two ends of the connector are respectively fixed to the exposed end of the first embedded component and the exposed end of the second embedded component.

[0005] However, the above patent still has the following defects: the defect of bolt offset can be compensated by welding the screw rod to the steel plate at a later stage, but before hoisting the prefabricated stairs, measurement activities and welding activities need to be carried out in sequence, which is cumbersome and labor-intensive and time-consuming, and will affect the installation efficiency of the prefabricated stairs.
