How many degrees of stairs are the most suitable for the stairs?
The applicable slope of the stairs is 25 to 40 degrees and the suitable slope is about 30 degrees.
Stairway aspect ratio is based on staircase slope requirements and different types of natural body steps (step) requirements to determine, in line with safety and convenience and comfort requirements. Slope is generally controlled at about 30 °, for only a few people use the service staircase is relaxed requirements, but not more than 45 °.
The applicable slope for the stairs is 23 to 45 degrees and the suitable slope is about 30 degrees
Safety stairs here only as a evacuation, generally less than 45 degrees and greater than 30 degrees is appropriate.
Ordinary indoor staircase slope is generally 20 degrees -45 degrees is appropriate, the best slope of about 30 degrees.
Special ladder
Safety ladder: slope is not greater than 45 °
Fire ladder: tilt slope of 60 ° ~ 80 °
Escalator: The gradient of the escalator is about 30 °
Stairs form
Stairs can be divided into single stairs, double stairs and multi-run stairs. The plane shape of the ladder has a straight line, a broken line and a curve.
Single run stairs the most simple, suitable for high-rise buildings;
Double run stairs the most common, there are double running straight, double running twists and turns, double run fold (parallel), etc., for general civil construction and industrial buildings;
Three scooters are three fold, T-style, split, etc., used for public buildings; scissors staircase by a pair of opposite pairs of double-running parallel ladder, or by a pair of overlapping and not connected single run straight up the ladder , The cross-section of the scissors-shaped cross-section, can also be more people through the flow and save space; spiral staircase is fan-shaped support in the neutral column, although walking less comfortable, but save space for less flow, ; Round, semi-circular, curved staircase, by the curved beam or curved plate support, step by step fan-shaped, fancy variety, modeling lively, full of decorative, suitable for public buildings.
