Primary Examiner: Ridgill, Jr.; James L.

Attorney, Agent or Firm: Bailey & Hardaway

A curved stairway is illustrated wherein the usual wooden components, including the stringers A, are provided with steel reinforcement, including metallic stringers B provided with cross bracing D and E in order to provide a composite structure affording rigidity with minimal reinforcement.

DETAILED DESCRIPTION It has been found that a curved stairway extending between a floor and a balcony may be provided wherein a pair of wooden stringers have steel reinforcement extending between them.
The reinforcement is such that flat bar stringer members may be curved to conform to the inner surfaces of the stringers and serve as a support for bracing affording rigidity to extend therebetween.
A number of structural sections, such as channel members, are spaced and extend between the flat bar stringers.
Suitable bracing is further provided by structural sections which extend diagonally as between corners of the channel members.
