Background technique

During cross-working operations, safety protective sheds and isolation measures should be set up within the fall radius. The safety protection shed is a protective scaffold erected to prevent falling objects from causing injury to people or damage to materials and equipment within the falling radius when working at high altitudes and at three-dimensional intersections. When constructing high-rise buildings, safety protection sheds with a width greater than 5 meters should be erected around the building with a vertical spacing of no more than 30 meters.

Safety protection shed construction sites generally use fastener-type steel pipe scaffolding to erect. First, cantilever steel pipes around the building floors, and fix them to the superstructure with cable-stayed wire ropes at the cantilevered ends. Then, horizontal steel pipe frames are erected on the steel pipes, and vertical steel pipe frames are erected at the outer ends. The steel pipe frame is then tied with bamboo skewers on the horizontal steel pipe frame, and plywood is tied on the vertical steel pipe frame to seal it.

Safety protection sheds built with fastener-type steel pipe scaffolding must be erected every 30 meters at a construction height, which consumes a lot of materials and labor. The erection and dismantling of the safety shelter is carried out at high altitudes, where there is a great risk of falling and being hit by objects; multiple erection and dismantling operations increase the probability of safety accidents.
