C-002里关于Stairs这块,好像楼梯宽有明确限制,但是爬高,没太看懂,请大神解释一下:
5.3 Stair pitch and proportion
The maximum pitch of stairs shall not exceed 38°.
The following formula shall be used in determining the stair proportion:
GOING + TWICE THE RISE = 630 mm +/- 30 mm
The maximum rise shall be 190 mm.
Treads shall be evenly spaced. The maximum allowable deviation of the rise dimension in a single flight of
stairs is +/-5 mm, including the first and last riser of every flight. Stairs for areas requiring installation
contingency, may incorporate an adjustment facility. The projection of the treads shall overlap one another
with minimum 20 mm.
5.5 Flight
There shall be a maximum of 16 risers in any single stair flight.
There shall be a minimum of two risers for any flight in a stair that has more than one flight.
In long, straight stairways, after a maximum of 36 risers in consecutive flights, there shall be a change in
direction of minimum 30°, or a landing of minimum 2 000 mm length.
