Calculation of spiral stairs Enter the required dimensions - The height of the stairs - outer diameter - Internal diameter - Number of steps - The thickness of the treads - The rotation angle of the stairs Help The length of steps in the spiral staircases should not be less than 80 cm Step width in the central part should not be less than 20-25 cm at the widest part - nor more than 40 cm. Spiral staircase step height can be greater than the height recommended for mid-flight of stairs. Normal step height for straight stairs is 16 cm, for spiral stairs - 18 cm In the place where the leg begins, step spiral staircase to be about 25-30 cm, on the edge - not less than 30-35 cm. The depth level is quite convenient. Then foot man will be on stage in full, not hanging over the edge. Step size spiral staircases. - length of the stage - step width in the widest part of - width of the workpiece stage - bank angle step

Ríomh an méid de na staighre adhmaid le withs Sonraigh na gnéithe de dhíth i milliméadair - Fad oscailt staighre - Ní rachaidh airde an dréimire - Leithead an staighre - Líon na céimeanna - An tiús na céimeanna - céimeanna Ledge - an tiús na sreinge nó an kosoura - risers thaispeáint LR - ardaitheoir dréimire treo SP - le seasamh an chéad chéim go dtí an leibhéal urlár an dara hurlár Gnéithe. Ríomh dearadh staighre adhmaid éasca le húsáid ar an teaghrán. Chinneadh an méid na n-ábhar. Na toisí cruinn na sonraí go léir. Líníochtaí mionsonraithe agus léaráidí de gach gné den dréimire. Treoirlínte mar áis staighre. Is é a ríomh staighre áise ríomh trí foirmle atá bunaithe ar fhad na páirce. Is é an fad an fear pháirc 60-66 cm, ar an meán - 63 cm Freagraíonn dréimire Compordach na foirmle: 2 chéim airde + leibhéal an doimhneacht = 63±3 cm. An Dréimire tilt is áisiúla - ó 30 ° 40 °. Ní mór chéimeanna staighre Doimhneacht freastal ar mhéid an 45 bróga - nach lú ná 28-30 cm Easpa féidir doimhneacht mar chúiteamh ar an chéim teilgean. Ba chóir go mbeadh airde Céim 20-25 cm
