摘要:
A modified construction for a non-linear or curved staircase employs a technique in which the treads (l7, 30) for the staircase are initially cut to the required shape and size. Flexible plywood boards (l5) of the same length and height as the required stringers are then attached to the treads with the treads positioned in the required locations and orientations so as to create a rigid self-supporting structure formed by the flexible boards (l5) and the attached treads (l7) and risers (l4) where required. The self-supporting structure is then finished by the attachment to the flexible boards of suitable laminations (l9, 20). Housed treads (l7) have the laminations applied to the outer surface of the boards. Exposed end treads (30) have the laminations applied to the inner side of the boards.
