Description
Complete set of CAD dwg drawings for Reinforced Concrete Spiral Helical Staircases Reinforcement Details. One of the most difficult design tasks, is now ready and available to use with every project.
Curved circular grand staircases or helical floating staircases are somehow difficult both to design and draw due to the geometry complexity.
Curved circular helical staircases are usually used architecturally to offer an iconic feature to a building, in contrast to a regular straight L or U shaped staircase. The most attractive feature is that they seem to floating ( thus the name ) without a centre or edge support. That is the reason that in some cases they are referred to as GRAND staircases.
Complex design made easy
Design of such floating continuous staircases is mainly done as if each staircase is a two-way slab or as a cantilever span with half the span of the staircase, with continuous top and bottom reinforcement. Unlike regular staircases where top reinforcement can be discontinued in the mid-span.
The drawing provides a clear and detailed depiction of the staircase helical layout, complete with all necessary reinforcement details.
- top & bottom reinforcement
- support reinforcement anchorage detailing
- steps secondary reinforcement
- starter bars, stirrups requirements

Generic and Adaptable Details
All staircase types can be used as is for any type of project as generic detailing drawings to illustrate the methodology for correct reinforcemnt.
Plans, Cross Sections & Elevation Views
Included with this set are plan views for every staircase type, reinforcement detailing both in plan view, cross section and elevation view as well as elevation views of the staircase.
