Are the stairs cast-in-place or customized?

The concrete staircase is a staircase which is cast and mixed with formwork on site. Concrete stairs are made and installed with formwork below, and the firmness is not as good as that of on-site pouring.

Cast-in-place reinforced concrete stairs are cast into a whole step, platform and platform beam on site, which has good integrity and strong earthquake resistance. According to the different structures, it can be divided into slab stairs and beam stairs.

1. Slab staircase: it is a sloping slab, with both ends supported on the platform beam, and the platform beam is supported on the brick wall.

2. Beam stairs: inclined beams are set on both sides of the stair section, and the inclined beams are placed on the platform beams. The load is transmitted from the pedal to the inclined beam and then from the inclined beam to the platform beam.
