Nta ntawm qhov kev pab cuam.

Muab xam saib loj, ntoo stairs uas kaw cov hlua.
Khom cov nqi ntawm cov khoom tawg yooj yim.
Lub caij nyoog qhov ntev ntawm tes taw.
Drawings xav paub thiab schematics ntawm lub stairs txhua yam.
Tswv yim rau zoojyim stairs.

Xam thaumtwg stairs calculated ntawm lub mis, raws li qhov ntev ntawm cov kauj ruam.
Stride ntev yog li ntawm 60 rau tibneeg 66 cm-63 cm thaj tsam li ntawm.
Kab ntsab ntaiv mis match: 2 theem siab + le theem = 63±3 saib.

Rau feem ntau nyiam inclination of ntaiv-ntawm 30 ° rau 40 °.
Rau ntawm qhov stair le yuav tsum 45 loj khau-tsis tsawg tshaj 28-30 cm.
Koj yuav tau compensate rau le ntawm lub notch qhov tsis muaj.
Nws muaj cov kauj ruam yuav tsum muaj li 20-25 cm.
