What are the angles of sloping roofs of buildings? How much does the height of 45% sloping roof scaffolding increase for every meter of lateral movement?
There are three ways to express the slope of the roof. There used to be the expression "a little water", but now it's not used.
1, angle method: expressed by the angle between the sloping roof and the horizontal plane, usually expressed as 5, 12, 30, etc. 45%≈24.2
2. Percentage method: when the elevation is 100 m and the elevation is n m, it means n%, such as 30% and 45%.
3. Ratio method: expressed by 1: n, and the ratio of N grade to height, such as 1: 3, indicates that the grade is 3m and the elevation is 1 m.. 45%≈ 1:2.2
4, 45% of the sloping roof, said elevation 100, up 45. If you move horizontally 1 m, the height will increase = 45/ 100 * 1 = 0.45 m.
