The common calculation of folded-beam stairs is as follows: 1, the total steps of stairs, the length, width and height of steps 2, the standard density calculation of structural columns and intermediate information platforms 3, the calculation of beam edges before and after inclined spans 4, the space length of inclined spans and the length of inclined spans on each floor (it can be used equally when laying steel bars and installing treads).
Folded-plate stairs and folded-beam stairs are exactly the same. The only difference is that the actual formwork support size of the rest platform is flexibly calculated according to the step width and cement thickness.
