Quarter-turn staircase

3D Design Volume Model
1

Good evening to you.

 

I'm tearing my hair out to draw a quarter turn staircase. I can't do it, it's simple.

It's a request from a craftsman who doesn't know how to design a staircase. At first I told myself that it was going to be done without too much worry, but what a neni!

I row from 5:00 p.m. and then it almost rings 10:00 p.m.

Can anyone help me?

To avoid taking time, I immediately attach what I have done

Thank you for your support.

Good evening

Can you make an imrpim screen so that we can see. There you put an assembly without parts. I ask for a screen print because right now I'm on a PC without SW.

Yes, it is possible to help you

but give information about your problem

via screenshots for all the players 

we don't all have the same version or the same log

It is a 1/4 spiral staircase swing 

This is a subject that has already been answered quite a bit on the site

do a stair search. 1/4 winding staircase on the site 

as well as on the Solidagora  website you will already find some answers 

among other things on my nickname I worked on it

waiting for + info and screenshots

So that everyone can see you can also make us an edrawing in exe so that there will be no version problem.

Thanks in advance

Rather than an assembly, preferably use the welded construction module, it is much more suitable for this type of study.

Hello
Use a 3D sketch, then create your shapes in welded construction for your steps...
Good luck

@ Franck51 is a specialist in the field he designs industrial staircases

With that you should already have something to move forward with

Good evening to you.

 

Yesterday when everyone seemed lost, and after hours of interruptions, I found how to do it. Now it's almost finished, it remains to be seen with the client how he wants the steps, but otherwise the rest works fine. I managed to distribute the swinging of the chews well

 

If anyone wants advice, I can help.

There seems to me to be several problems on your staircase

The angle is quite large 

the low number of steps

the height of these said high steps

The stride may not be in line

Have you taken the refs following this link

http://lionel.ponnelle.pagesperso-orange.fr/Page2.htm

otherwise yes he looks good except my remarks above

explain how you designed this staircase

awaiting completion

I agree with gt22 and we must not forget the guardrail. Look at the file I put in PC. I had downloaded it a few years ago when I did my 1st staircase.

you are unfortunately not wrong.

I followed the Philippe Berger method,

http://philippe.berger2.free.fr/Bois/Systemes%20Constructifs/Escaliers/les_escaliers.htm

And it looks like this. The temia is not big, and I don't really have a choice because it's a staircase that will go in an Alsatian house renovation, i.e. small.

The ceiling height is 2300 mm, the hopper is 2050 mm and 1550 mm width is 900 mm.

I also used your excel file Manu 67, but it tells me that a value is too high, so I started as the craftsman asked me on 11 steps.

Here I have 209.1mm of step height and a tread of 204.14 mm.

It must be said that I preferred to put a larger tread, since the descent is quite steep, so that the foot rests better, at least on a larger surface.

Is it good or not?

Thank you for your feedback.

204 step height it is a steel industrial workshop   type staircase

it's steep to go up and down  it's guaranteed to be a pain in the ass for domestic use

but since you have no choice and you still stay within the limits

So  it's okay you have responded to the wish of your craftsman

Well done

Hello

I followed this post without participating because I have no knowledge in the matter, but I realize that 2 days ago @f1b didn't know how he was going to get out of it with his staircase and today it's done. Well that's what the lynkoa community is all about, congratulations to all the participants.

May the force be with you.

For my part, I always try to stay in 18 and 19.5 cm step height. You also have to think that children could ride them.

yes I know, and so you think it's too high 209 mm?

Do we agree that if I make it smaller, it will add steps, and therefore the tread will be smaller?

If it really doesn't look good, I redo my calculations, no problem.

other people agree with Manu67?

Helo the company.

 

I redid my calculations by adding a step, so 12 steps in all with a 100 mm landing step (included in the 12)

I go from a 240 mm tread to 217.9 and the step height is no longer 209.1 but 191.6 mm.

That's better, isn't it?

that's what some people were advocating...

Am I going like this?

YES IT'S MUCH BETTER FOR ME 

YOU ALSO HAVE THE OPTION TO CREATE YOUR OWN STAIR NOSING

TO ENLARGE THE DEPTH OF STEP

and/or limit again even if it means skipping the finish  step and leaving only the stair nose which will give a little more comfort 

it's a subject;-)

The comfort of a staircase is appreciated when going down, not going up.

@+

you make us some screenshots with the sides

and show us your way of proceeding

thank you @+

So yes I'm done. Yes, I managed to do it when all seemed lost!.

I went to the site this afternoon, to take the real sides, (hourly) because it didn't exactly correspond to what the arisant had taken. In addition, the house is not a mess but I am sitting there. (I hope).

So it looks like this:

 

As for the 2D plans I made to draw each step seen from above, here is the detail. Explaining the whole thing would take a long time, but that's the method

http://philippe.berger2.free.fr/Bois/Systemes%20Constructifs/Escaliers/les_escaliers.htm.

 

A few shots? Here we go.

 

That's the work.

I contacted the laser cutter, just give him the files of the steps in *.step, and roll my hen..

It has a lot more faces like that. And there I think you find yourself better in step height (if you managed to get  191.6 mm) ..
