The sliding type safety net for installation and construction of the portal steel structure as claimed in claim 1, wherein the steel wire ropes (7) are respectively connected to each corner of the safety net (8) for laying and unfolding the safety net (8) to enable the safety net (8) to be in a flat and tensioned state.
8. The sliding type safety net for installation and construction of the portal steel structure according to claim 1, wherein two ends of the safety net (8) can be connected to the slide ways (9) through snap rings and can slide on the slide ways (9), due to the fact that the portal steel structure construction is not suitable for laying safety nets in a large area and construction personnel perform inserting construction in different areas in the construction process, the safety net (8) adopts a split safety net, and multipoint safety protection on the construction personnel in different areas can be achieved through sliding of the split safety net.
