Stairs Types and Design for your new House

In general, the shape of the steps determines the stair types utilised in building construction. There are several sorts of stairs, including Straight stairs, Turning stairs, and Continuous steps. A staircase is a set of stairs that leads from one floor to another, generally within a structure. The chamber or inclosure in which a building’s staircase is placed is known as the staircase. A stairway is the aperture or area occupied by the stair.

Types of Stairs – Staircase Classification:

There are three major classifications for stairs:

  1. Direct stairway
  2. curved stairs
  3. Continuous stairs

Straight stairway

In most cases, the width provided for compact homes is very retractable. Therefore, this form of straight stair is employed in situations when there is a direct connection between two floors. This staircase may consist of a single flight or many flights with landings.

Turning staircase

Turning stair treads are subcategorized as:

  1. Stairs with a quarter turn rise and run
  2. Half twist stairway ( dog legged stairs)
  3. Three-and-a-quarter turn stairway
  4. Separated stairways

Quarter turn stairway

A quarter turn stair is one that changes direction either to the right or to the left, but the turn is achieved by incorporating a quarter space landing or winders. In these kind of stairs, the flight of steps rises and rotates 90 degrees at the landing as it connects two distinct levels. Thus, it is also known as an L-stair. Again, there are two sorts of quarter turn staircases.

3.1. Quarter turn newel stairs

This form of staircase has visible newel posts at both the beginning and finish of the flight. At the quarter turn, either quarter space landing or winders are possible.

3.2. Stairs with a geometric quarter turn

In geometrical stairs, the stringer and railing are continuous and there is no newel post at the landing.

In the case of half-turn stairs, the direction is reversed or 180 degrees modified. Such staircases are extremely frequent. There are three sorts again.

4.1. Dog-legged stairs

This term is given because to its appearance in sectional elevation. It belongs to the genre of newel stairs, which have newel posts at the start and finish of each flight.

4.2. Open half-turn newel stair

In this form of open newel half turn stairs, the outer strings are separated by a gap or well. This is the sole difference between it and the doglegged stair.

4.3. Half turn geometric stairs

In the case of geometrical half turn stairs, the stringers and handrails are uninterrupted by a newel post. These stairs may feature a half-space landing or no landing at all.

Stairs with quarter turn

In the case of three quarter turn stairs, the stair direction changed three times, with the higher flight crossing the lower flight. These staircases may have either newels or open newels. This style of stair is typically employed when the vertical difference between two stories is greater and the stairwell length is limited.

Separated stairways

Commonly found in the entry halls of public buildings are staircases with two separate sections. At the landing, the bottom flight splits into two smaller flights, with one going to the left and the other to the right. It may be newel-type with a newel post or geometrical with a continuous stringer and handrails.

Continuous stairs

This form of staircase has neither an intermediate landing nor a newel post. They have a geometric form. These may be of the following varieties:

  1. spiral stairways
  2. Spiral stairs
  3. spiral stairways

Circular or spiral staircases are often constructed of R.C.C. or metal and are installed in locations with limited space. These are sometimes used as emergency stairways and are located at the rear of a structure. These are not comfortable because each step is spiral and causes soreness.

The structural design and construction of a helical stair is quite complex, despite its attractive appearance. It is composed of R.C.C, which requires a substantial amount of steel to resist bending, shear, and torsion.
