H5 - Plan Winder Stairs - LT #2 Flashcards
Given the minimum run at the inside of the tread, what is the dimension of the offset to the convergence point for a 30 degree winder tread?
260 MM
Given the minimum run at the inside of the tread, what is the dimension of the offset to the convergence point for a 45 degree winder tread?
150 MM
What is the first step in designing winder stairs?
Calculate the number of risers and rise per step based on total rise from finished floor to finished floor
When will you design an L-Shaped stairwell opening?
When length of stairwell opening is more than the run of the upper flight.
Good stair builders spend their time how?
Planning takes almost as much time as the building.
What is the purpose of winder stairs?
Design a total flight of stairs so that the run taken at the line of travel on the three angular treads is close to or the same as the run on the conventional treads landing to and from the winder section.
Section above winders is referred to as:
Upper flight of stairs
Section below winders is referred to as:
Lower flight of stairs
When the design of a building fixes the run of either upper or lower flight, this is called a:
Trapped Run
Direction of joists relative to the opening derminesL:
The framing requirements,
Rectangular openings are used when:
If minimum headroom is achieved within the run of the upper flight, the opening will be rectangular.
L-Shaped openings are used when:
If the minimum headroom is not achieved within the run of the upper flight, the opening will be L-Shaped.
Framing an L-Shaped opening is more difficult than for a rectangular opening and depends on:
Direction on which joists are running.
What is a skirt board?
Term used for the baseboard that follows the slope of the stairs. It needs to miter to the baseboard at the top and bottoms of the staircase.
