General Guideline

maszu650 — 2019-02-15 01:43:57 UTC

The following are some of the general guidelines to be considered while planning a staircase:

1)The respective dimensions of tread and riser for all the parallel steps should be the same in consecutive floor of a building.

2) The minimum vertical headroom above any step should be 2 m.

4)Generally, the number of risers in a flight should be restricted to twelve.

5) The minimum width of stair should be 850 mm, though it is desirable to have the width between 1.1 to 1.6 m. In public building, cinema halls etc., large widths of the stair should be provided.

Staircase terminologies

maszu650 — 2019-02-15 01:44:40 UTC

The different terminologies used in the staircase are given below:

1) Tread: The horizontal top portion of a step where foot rests is known as tread. The dimension ranges from 270 mm for residential buildings and factories to 300 mm for public buildings where large number of persons use the staircase.

2) Nosing: In some cases the tread is projected outward to increase the space.

3) Riser: The vertical distance between two successive steps is termed as rise. The dimension of the riser ranges from 150 mm for public buildings to 190 mm for residential buildings and factories.

4) Going/ flight: Going/flight is the horizontal projection between the first and the last riser of an inclined flight

Draw TWO sections.

1) One section contains a cross section from roof to floor showing a type of timber frame construction

and

2) One section contains a cross section from floor to foundation showing a type of timber staircase in masonry construction

Question 2

maszu650 — 2019-02-15 01:57:18 UTC

What is staircase terminologies?

Question 3

maszu650 — 2019-02-15 01:58:01 UTC

How many basic types of staircase available in construction?

Question 4

maszu650 — 2019-02-15 01:58:29 UTC

A builder recommends a ‘rule of thumb’ for building a staircase: keep the dimensions for the ‘rise’ between 150mm and 175mm if possible and around 255mm-300mm for the ‘thread’.

1. Using this rule, design a simple staircase suitable for an exact distance of 3500mm from the ground floor to the first floor of a house with a horizontal distance available of 5m.

2. How many ‘threads’ and rises would you use?

3. What dimensions of ‘threads’ and rises would you use and why?

4. What assumptions do you make?

5.What other factors you need to consider in a staircase design?

Question 3. How many basic type of staircase available in construction ?

2023-12-27 03:45:16 UTC

There are three types of stairs in construction which are :
1. Straight stairs
2.Turning stairs
3.Continuous stairs

1. Straight stairs
-is the most basic and common stair design available in construction
-the easiest to build, easiest installation of railings and handrails

2.Turning stairs
-are sub classifieds into :
1. Quarter turn stairs (L-shaped)
2.Half turn stairs (U-shaped)
3.Three-quarter turn stairs
4.Bifurcated stairs

•Quarter turn stairs
-change its direction whether left of right which turns 90 degree art landing
-two type: newel quarter turn stair and geometrical quarter turn stair

•Half turn stairs
-its direction reversed, or changed for 180 degree
-three types: dog-legged stairs, open newel half turn stairs and geometrical half turn stairs

•Three quarter turn stairs
-The direction of stairs changed three times with its upper flight crossing the bottom one in the case of three quarter turn stairs

•Bifurcated
-wider flight at the bottom, which bifurcates into two narrower flights, one turning to the left and other to the right

3. Continuous stairs
- neither have any landing nor any intermediate newel post

These are may be of following types.

•Circular stairs

•Spiral stairs

•Helical stairs

Question 2

2023-12-27 04:11:13 UTC

Stairwell: The spatial opening, usually a vertical shaft, containing an indoor stairway; by extension it is often used as including the stairs it contains.

Flight: A flight is an uninterrupted series of steps

Closed Stair: A closed stair has both treads and risers.

Open Stair: Is a stair that doesn't have risers. Stairs with open risers are built with only the treads, leaving the vertical spaces between them uncovered. This style is mpst common in contemporary interiors where the stairway may be freestanding.

This design can be dramatic and attractive.
