landing for stairs to pioli (marinara)

[gil]

in the case of stairs to the marinara, I did not find indications on the distance to respect between the ramps when I have to put a landing between the two. or the distance indicated by the question mark in the photo below.
Does anyone have any idea about this? I do not think there are any indications in the norm uni en 1422-4.
thank you for the time you can dedicate me.

I don't think there's a specified distance, or at least I like you didn't find it. the common sense tells me that you could respect rule 14122-3 at the point where it speaks of the distance between the parapets that must be 75 mm (min) - 120 mm (max).

I thought I would do as a drawing under (100mm). but I haven't got a regulatory response.
Instead, the designer drew them at a distance of 1 meter if I propose variations I will have to justify it somehow.

is written as it must be done:

to ensure a secure grip of the hand between two consecutive vertical climbers of the scale ramps, a space should be provided > 75 and < 100 mm between the mounts or a handrail must be installed (see ISO 14122-3).
I think we can reason from here.
eye that if to put a parapet, the air between parapet and parapet should be correctly sized (depending on the shape of the parapet). if mounted straight, between 80 and 120 mm

thanks to all the answers.
