A plurality of brackets formed with female threaded holes provided on either side of the fixing bolt and the vertical bar to be fixed by pressing the slab by; Eye bolts having one end fastened to the female threaded hole of the bracket and supporting the wire at the other end; Wires that pivot around the plurality of brackets and are supported by eye bolts fixed to the brackets; Turnbuckles provided at both ends of the wire to adjust and fix the tension of the wire; And a network provided on the wire that turns the plurality of brackets and bound and fixed by a binding member; a technique consisting of a bar has been previously suggested.

In addition, in another prior art Publication Patent Publication No. 10-2018-0007838, a scaffolding pipe that is bound to the outside of a bracket fixed to the inner wall of a building; A support frame fastener coupled to the scaffold pipe as a clamp; a support frame coupled to the support frame fastener; In including a brace for supporting a support frame by fixing one end to an outer wall of an upper floor of a building and a safety net coupled to the support frame, the support frame includes a pair of vertical bars; The pair of vertical bars are interconnected and composed of a plurality of horizontal bars that are laid out at regular intervals, and the support frame is guided through a U-shaped guide ring installed inside the lowermost horizontal bar and the uppermost horizontal bar to the endless track A rope connected rotatably is installed, and a net detachable clip for attaching and detaching the safety net is installed at the top of the upper side of the rope, and the lower rope on the opposite side is connected to the support frame fastener as a connecting wire. Fastened with a clip for fixing the rope A technology for installing a fixing ring has been previously disclosed.

In addition, in Patent Registration No. 10-1049173, which is another prior art, two horizontal support bars provided to be opposed to each other in the longitudinal direction and each front side bent inwardly and having a reinforcing bar welded to the inside; Doedoe coupled to the upper part of the two horizontal support bars by welding, long in the longitudinal direction of the horizontal support bar and a guide frame having a drawing hole through one surface of the front end; A fixed pulley coupled to the inside of the front end of the guide frame; A movable pulley configured at a position corresponding to the fixed pulley, the movable pulley is coupled to the front end, and the locking part hinged to the rear end side by its own load is coupled with a pin, and a hook portion on which a safety net is hung at the top. A safety net hanger that is drawn into the inside of the guide frame and ascends and descends along the inside of the guide frame; A technology that includes a locking portion that hangs a locking portion configured at the rear end of the safety net hanging portion has been pre-registered.

However, the above conventional technologies are intended to prevent safety accidents caused by worker falls and falling objects at high construction sites, but due to the nature of being installed based on a scaffold structure, the construction of the scaffold structure must be preceded, and due to the heavy and complex installation structure, construction and During demolition, lifting equipment including a crane must be used, resulting in a significant increase in construction cost.

Therefore, there is a need for a new method capable of solving these problems.
