Description of the Related Art Conventionally, in the stairway portion of a constructed building, the riser surface and the tread surface of the staircase in which concrete is cast in situ are surface-finished with mortar. In this surface finish, it is difficult to finish the mortar with the iron on the riser that intersects the horizontal tread almost vertically.Therefore, the veneer formwork formed in the same shape as the length of the riser faces the riser with a gap. It stands upright and both ends of this veneer formwork are locked with battens nailed to both side walls. After that, mortar is filled in the inner gap between the veneer formwork and the riser surface, and after the filled mortar is solidified, the mortar is fixed to the surface of each riser face while demolding the veneer formwork, and finally, horizontal. Mortar is spread on the tread and finished with a trowel.

Veneer formwork with a mortar finish on the riser surface is manufactured one after another according to the shape of the riser surface of the stairs, and the stairs are fixed while the both ends of the veneer formwork are secured to the battens nailed to both side walls of the stairs. Since the veneer formwork is assembled facing the surface, these operations are complicated, and it takes time and effort to repair the holes made of batten nails with mortar when the veneer formwork is demolded. . Furthermore, the veneer mold is difficult to remove because the solidified mortar adheres firmly, and the accuracy tends to decrease when the veneer mold is reused due to the adhesion and deformation of the mortar on the veneer mold, and repeated use. However, there was a problem that the construction cost was high because it could not be done.
