scale

[F.Devis]

good morning, I'm trying to develop this scale with a central mount, which is a tube ø 133mm, the steps are 950 mm wide and raised 172,105 mm and pedestrian 320 mm, I can't do properly the steps in the curve

 

[Marco F inox]

I can't see the drawing: because there is a central tube, is it a spiral staircase? If so, how do you say the pawn is 320 mm. What is the difference in height between the two floors?
What is the total angle rotation?

 

[F.Devis]

No, it's not a spiral staircase. Can't open the step format of the drawing? to see you need some other format?

 

[infallibile_GF]

the steps of the curve do not go, since the pawn within the curve is reduced almost to zero, instead it should always remain at least 200-250mm.

 

[F.Devis]

that would be the optimal, but for the shape and lengths of the pipe you do not succeed, and therefore the step is reduced in the inner tip up to about 60 mm, but the problem is not that and 'to be able to draw the under steps equal to the other steps using references that make them look equal

I suggest you get the shape of the step with the surface controls and convert to sheet when you have already got the correct shape.

I am curious, do you want to show a design to me, with another format like so many?

 

[F.Devis]

Can you tell me what size you like?

Can you tell me what size you like?

I don't have winrar, so I can't open it. It would also be enough for a scanned design, so much to understand the problem, because it seems very interesting.
thinks that sometimes the solution is not found, only because you consider it an extra step.

 

[Cooperman]

As winrar, this is not all other things. What do you think about it as fast as possible?
Let me tell you, I tell you what I say, let me tell you what is a story.

The same is very difficult at the static level, the only thing that comes to my mind is to make the support brackets equal but tilted/folded differently. cmq beautiful ladder, insists ,

 

[Marco F inox]

Thank you, I can see it perfectly. Sure would have created fewer problems, if the internal radius of the curve had been wider.
to have a larger pawn, you have to bring to three the curved pawns that are now 4.
you have to recalculate the lifts (with the step less), then you have to think of a curved tube on the development of the 90°, which will be less inclined than the terminals rights.
in substance the support tube, cannot be obtained from a simple bending, but the set of three thick tubes results.

 

[F.Devis]

yes of this you are right, but the pipe is already there because made by an elderly customer, that about 20 years ago had already made it do so and so now is this the current situation

 

[fgmec]

If I put the file on the table, I see that until the 10th step the lift is correct (about) , then there are high values

 

[F.Devis]

total height is 3490 mm
