Referring to fig. 1 and 2, the clamp 10 includes two semicircular hoops 11, one ends of the two hoops 11 are rotatably connected, the other ends of the two hoops 11 are respectively extended with a lug 110, the two lugs 110 are fixedly connected through a locking piece 13, one of the hoops 11 is horizontally and outwardly provided with a sliding rail joint 12, and the sliding rail joint 12 is provided with a screw hole.

As shown in fig. 2, the locking member 13 includes a locking screw 131, one end of the locking screw 131 is rotatably connected to a lug 110, and the other end of the locking screw 131 is movably screwed with a locking nut 132, wherein: after the locking screw 131 is inserted into the locking groove (not shown) of the other lug 110, the locking nut 132 is screwed to make the locking nut 132 tightly abut against the locking groove of the lug 110, so as to fix the two hoops 11 by the locking piece 13.

In practical implementation, the clamp 10 may also adopt other structures without limitation.

In practical designs, the rail 20 is secured to the clip 10 by the threaded engagement of the fastener 30 to the rail connector 12, wherein: as shown in fig. 3, the fastening member 30 includes a fastening bolt 31 movably disposed on the rail bottom surface 21 of the slide rail 20, a through hole (not shown) for passing the fastening bolt 31 is disposed on the rail bottom surface 21 of the slide rail 20, a bolt head of the fastening bolt 31 is disposed inside the slide rail 20, a fastening nut 32 is screwed on a portion of a screw rod of the fastening bolt 31 extending out of the slide rail 20, the fastening nut 32 is fixedly welded on the fastening bolt 31, and the fixing welding of the fastening nut 32 is aimed at only allowing the fastening bolt 31 to rotate relative to the rail bottom surface 21 of the slide rail 20, and generally, the bolt head of the fastening bolt 31 and the fastening nut 32 are respectively disposed close to the inner side and the outer side of the rail bottom surface 21 of the slide rail 20; as will be understood with reference to fig. 2, the slide rail 20 is fixed to the clip 10 by the screw of the fastening bolt 31 protruding out of the slide rail 20 and the screw of the fastening nut 32 being screwed into the slide rail joint 12.

As shown in fig. 3, the C-shaped slide rail 20 includes a rail bottom 21 and two rail side walls 22, and the two rail side walls 22 are bent inward.

As shown in fig. 4, the sliding hook 40 includes a hook frame 41 in a form of a lying T, wherein: the hook frame 41 is composed of a horizontal bar 411 and a vertical bar 412 which are vertically connected to each other; the end of the horizontal rod 411 is provided with a hook 42 with an upward opening, the upper and lower ends of the vertical rod 412 are provided with sliders 44 for abutting against the inner sides of the rail side walls 22 of the slide rail 20, and the upper and lower sliders 44 respectively abut against the inner sides of the upper and lower rail side walls 22 of the slide rail 20, so that the sliding hook 40 can only slide but cannot be separated from the slide rail 20.

As shown in fig. 4, a stopper 43 is elastically and rotatably installed at the opening position of the hook 42. When an external force is applied to the flap 43, the flap 43 rotates to open the opening of the hook 42. When no external force is applied to the flap 43 or the external force is removed, the flap 43 seals the opening of the hook 42. Due to the design, after the rope joint of the safety net is hung in the hook 42, the falling-off phenomenon of the rope joint can be effectively prevented through the blocking piece 43.

In practical designs, the slider 44 is preferably a resilient slider, such as a rubber slider. The elastic block is designed to ensure that the sliding hook 40 can flexibly slide in the sliding rail 20, and at the same time, the two sliding blocks 44 can be more closely attached to the inner sides of the upper and lower rail side walls 22 of the sliding rail 20, so as to effectively prevent the sliding hook 40 from being separated from the sliding rail 20.

In practical implementation, if the length of the slide rail 20 is not enough, two adjacent slide rails 20 can be spliced together through a connecting member, so as to meet the requirement.

During construction, a plurality of clips 10 are fixed to each truss 50. The rail joint 12 of each clip 10 should be maintained at the same horizontal straight line for the same truss 50, and then the rail 20 having the plurality of sliding hooks 40 mounted thereon is fixed to each clip 10 by the fastening member 30, and the rail 20 should be in a horizontal state.

When in use, the rope joints on the two sides of the safety net are respectively hung in the hooks 42 of the corresponding sliding hooks 40 on the sliding rails 20 arranged on the trusses 50 on the two sides. When roof construction is required, the safety net can be quickly tensioned and fully paved between the trusses 50 on the two sides by sliding the sliding hooks 40 on the sliding rails 20. When the gap between the trusses 50 needs to be used as a temporary hoisting channel, the safety net can be quickly folded and retracted by sliding the sliding hooks 40 on the sliding rails 20, so that the hoisting requirement is met. After the hoisting is finished, the safety net can be immediately restored to the full state by sliding the sliding hook 40 on the sliding rail 20, so that the roof construction is continued.
