Prefabricated concrete assembly houses have become the choice of many people due to their low cost, inherent advantages of manufacturing materials, quick installation, short construction period, environmental protection and energy saving. Prefabricated stairs, as an assembly project, are one of the indispensable prefabricated components. Usually, after the prefabricated stairs are cast, the roughcast needs to be sorted and repaired. The traditional construction method is to randomly lift and repair the prefabricated stairs on site after the mold is removed after casting. This construction method can easily cause the product to tilt or fall, causing the prefabricated stairs to be damaged by bumps and may also affect construction safety.
