The overlapping portion of the piece 5 and the riser plate 3 is fixed with a tapping screw 17 or the like and assembled. This procedure is sequentially repeated to form the staircase base 11 having a required size.
After the stair base 11 is completed, the stair nosing member 8 is attached as shown in FIG. 3 from a design standpoint or a functional standpoint such as tread size. Further, a surface finish 12 such as a decorative board material or a carpet is stretched on the surface of the stair base 11, thereby producing the residential staircase 10.

In the residential staircase of this embodiment, as shown in FIG. 4, a stair foundation is formed by a plurality of steel step members on which a gypsum plate 4 is stuck near the longitudinal center of the back surface of the riser plate portion 3. Therefore, even if the riser plate portion 3 vibrates due to elevating and lowering, the gypsum plate 4 functions as a vibration damping material and a sound absorbing material for the riser plate portion 3, so that the stepping sound and the like can be reduced. Also, especially when going up and down stairs
Is performed near the center of the stairs,
Although it often vibrates, the plaster plate 4 is moved in the longitudinal direction of the riser plate 3.
