Important Measurements: Math, Physics, and Stair Safety
http://www.mccarthyhomes.com.au/
The stairs are normal fixtures of a home’s architecture. Apart from being the place forphotographs for prom nights and wedding
days,
it
is
also
a
day-to-day
utilitarian component of any property that dictates the natural flow of a home.
This is why every home builder must take a look at the scientific side of the staircase
before
building
one.
Explained
below are the math, physics, and safety standards of staircases.
Angle matters The
International
Residential
Code
allows each step to be only as high as 7 ž inches. This measurement plays a key role in finding out how many steps there will be in a home
and the
architecture.
The
angle math
of
the
here
staircase’s takes
into
consideration the total rise from the first floor to the second floor in inches
. This number goes through division with the industry standard of 7 ¾ inches (it could be smaller, depending on the architect’s preferences).
This is just the vertical side. To measure
the
horizontal
angle,
the
architect has to take into account the carriage – or in other terms, total run – of the staircase. Only after defining this figure can the architect plot out the total area the staircase would take.
Weight issues Another point of consideration is the amount support.
of
weight
This
is
the
staircase
something
can
builders
address through the use of standardcompliant stringers – or the sawtooth structure that holds together the steps of a staircase. The stringers alone, however, cannot
do
all
the
work.
Thus,
it
is
important that this frame has a sturdy structural element to attach onto.
Tread measurements Once the two things above have been
taken into account, the
final
touches would involve three things: the tread, the riser, and the rail. The tread is the surface people step on – the horizontal area of the step. The riser pertains to the vertical side. Lastly, the rail is the bar on the side that prevent falls.
The tread should be around 12 inches in measurement. The riser, as mentioned earlier, cannot go beyond 7 ž
inches.
The
rail
should
be
somewhere around 34 to 38 inches from
the
tread,
and
it
should
encompass the entire staircase.
Do
note
that
international
standards require at least 80 inches of headroom in all staircases.
There is a lot more thought into staircases than what most people would think. This is not just about putting together wood planks that act as steps. As a matter of fact, builders take mathematical into
and
consideration
physical to
concepts
create
safe
staircases for any property’s residents. Resources: http://www.mccarthyhomes.com.au/ http://www.practicaldiy.com/carpentry/ staircase/staircase.php https://archive.org/stream/gov.law.icc.i rc.2012/icc.irc.2012_djvu.txt
