Horizontal cantilever protective net construction method suitable for irregular building facade

The invention relates to a construction method of a horizontal cantilever protective net suitable for an irregular building facade. Comprising the steps that 1, two steel wire ropes are fixed to the upper portion of a cantilever protective net; 2, calculating the position of a lifting point according to the gravity center position of the cantilever protective net; 3, fixing the free end of the steel wire rope at the position of the lifting point by using a rope clamp; 4, the horizontal overhanging protective net is hoisted in a two-point mode; 5, the cantilever net is installed; 6, after the cantilever net is hoisted in place, unhooking is conducted; and 7, removing the horizontal cantilever protection. The construction method of the protective net is simple in process principle and convenient to operate; the cantilever protection angle can be automatically adjusted, and the safety risk of college entrance examination operation is reduced; furthermore, the hanging point is located in the middle of the cantile
