STAIRS STAIRS, TYPES, AND HOW THEY WORK
What are Stairs? A flight of steps is known as a stair. Stairs provide easy access to various levels of the home. All styles of homes, except the ranch with no basement have stairs. ranch A flight is a stairway or set of steps between one floor or landing and the next.
Types of stairs Six general types of stairs are commonly used in residential construction. They are: Straight flight stairs L stairs (or dog-leg) Double L stairs U stairs Winder stairs Spiral stairs
The Straight flight stairs The straight flight or straight run stairs are the stairs used most in new home construction. Straight stairs, as the name implies, have no turns. These stairs are not as expensive to construct as other types of stairs.
The Straight flight stairs
L-Stairs (Dog-leg) The L stairs has one landing at some point along the flight of steps. If the landing is near the top or bottom of the stairs, the term Long L is used to describe the difference
Double L Stairs Double L stairs require two 90 degree turns along the flight. They may be used when space is not available for either the straight or L stairs. Double L stairs are not frequently used in residential construction.
Double L Stairs
U-Stairs U Stairs may be constructed may be either as wide U or narrow U stairs. Both have two flights of steps parallel to each other with a landing between. The difference between wide and narrow U stairs is the space between the two flights.
Winder Stairs Winder stairs have “pie-shaped” steps which are substituted for a landing. This type is used when the space is not sufficient for the L stairs.
Spiral or Circular Stairs Spiral stairs, as a rule, are not very safe since they generally have winder steps. They may be used where little space is available.
