[0002] Prefabricated stairs are one of the commonly used components in prefabricated buildings. The prefabricated components of prefabricated stairs are mainly prefabricated concrete pedals, platform plates and supporting structures. The main support methods of stairs are wall-bearing, cantilever stepping and beam-bearing. They have the advantages of high efficiency, fast construction speed and high quality controllability. As escape routes, prefabricated stairs also have high quality requirements, so they need to be tested after production.
