[0002] At present, prefabricated stairs are usually placed in layers on the square timber on the ground. This method has great disadvantages. Stairs are bending components. The stacked stairs transfer the load to the lower stairs layer by layer. Therefore, the lower stairs are prone to cracks at the bottom of the stair treads, especially at the junction of the stair treads and the platform. In addition, if the bearing capacity of the foundation is poor, the safety awareness of the factory construction workers and the management staff are negligent in management, it is easy to collapse due to uneven settlement of the foundation, causing safety problems. At the same time, since there is no standard stacking rack, the prefabricated stairs are only placed on the square timber, and the number of stairs that can be placed at the same position is limited. If a large number of stairs are produced in one batch, more space is needed to stack the stairs, resulting in a waste of space. Summary of the invention
