Anti-falling safety net

The invention relates to a safety device for architectural engineering construction, in particular to an anti-falling safety net. The traditional anti-falling net needs to use a great number of steel pipes with heavy weight, and large-scale horizontal and perpendicular transportation equipment is needed to install the traditional anti-falling net; safety can not be ensured during erection, and the time for the erection is long; and when a falling object is too large, a hanging steel pipe support is easily pulled to deform. The invention relates to an anti-falling safety net which comprises a net frame, wherein the net frame is connected with a building, and the net frame comprises trusses; the trusses are connected with a building structure, and the anti-falling net is arranged between the trusses; connecting steel plates are installed at the inner ends of the trusses, and are fixed on the building structure through connecting pieces; and a steel wire rope threading ring I is arranged at the outer end of each
