Drawing of stairs

[nimhed]

Hello
Does anyone have a drawing of a staircase with 90 degrees without a landing?

Preferably a comfortable staircase, not a very steep attic staircase.

I would like to have an idea of how much space such a staircase takes up.

What size the hole in the ceiling should be, etc.

My basement stairs are 80 cm wide, 170 cm on the long side and 120 cm on the short side, at a 90-degree angle without a landing. 12 steps long with a step depth of 19 cm from nose to nose and a step height of 21 cm. This is not comfortable to walk in, rather steep, but it works. I go up and down it about ten times a day. I would recommend increasing both the step depth by a few cm and decreasing the step height by a few cm. It's often said that step height + step depth + step height should be about 63 cm. As such, it's not really that but 61 cm. In any case, this takes up an 80 x 170 cm hole in the floor. How have you thought about building the stairs?

The most important task that one needs to know to be able to provide a sensible answer is the floor height, i.e., the distance between the two floor levels that the staircase needs to bridge.

BBR says a step depth of at least 25cm if I remember correctly.

 

[justusandersson]

Yes, in the outer walking line for stairs to one or more apartments. Within an apartment, it is 22 cm.

Yes, the idea is to build it myself. In my head, it's going to go just fine

I don't have the measurements in front of me, but it's a bit in the future. I guess the height is around 3m and that I have about 3m straight staircase before I have to turn 90 degrees.

I'll measure next time I get the chance, and we'll see where it ends up.

Just write to me on Pm and I can help with how to think

Unfortunately, I think it won't be a good staircase if you follow that model. There will be different tread depths in the walking line, which is very annoying. You cannot limit the angled treads to the corner itself but must start earlier and end later. The difficult part is drawing the staircase, not building it.

Many thanks!
Everything is of interest

I sadly believe that it won't be a good staircase if you follow that model. There will be different tread depths in the walking line, which is very annoying. You cannot limit the angled treads to just the corner but must start earlier and end later. The difficult part is drawing the staircase, not building it.

I think unfortunately you are right

Hmm, went like this

Then let's try this one instead

If you remove http:// from the mastodon link, it also works and shows another example.

 

[justusandersson]

Great example showing how the inclination spreads over a larger distance. Note that the stringer on the right side is slightly curved upwards.

Perhaps the best thing would have been to find a demolition object with a stylish staircase and dismantle and modify it. Or does it seem unreasonable to have such luck?

There is a nice book on how to make curved stairs written by Hans Nilsson.

It can probably be borrowed from your local library.
