[0015] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0017] like Figures 1 to 3 As shown, a combined parapet edge protection device includes: two support frames, and a protection system fixed between the two support frames, wherein the support frames include: a column screw 1, an L-shaped steel bar 2, and a first nut 3, wherein the column screw 1 is screwed to the first nut 3, and the L-shaped steel bar 2 is formed by folding the steel bar in half and passing around the first nut 3 and fixedly connected to the outer wall of the first nut 3, wherein the column screw 1 is closely attached to the outside of the parapet 4, the transverse portion of the L-shaped steel bar 2 spans the top of the parapet 4, and the vertical portion of the L-shaped steel bar 2 is placed inside the parapet 4. The support frames and the protection system form a protective whole for edge protection of the parapet 4. The length of the cantilevered portion of the column screw 1 above the parapet can be adjusted by rotating the column screw 1 and the first nut 3.

[0018] The protection system includes a second nut 5, a fixing ring 6, a steel wire rope 7, and a dense mesh safety net 8. Two second nuts 5 are screwed onto each column screw 1. The two second nuts 5 are respectively placed at the middle and top of the column screw 1 cantilevered above the parapet 4. The outer wall of the second nut 5 is fixedly welded with the fixing ring 6. The two ends of the steel wire rope 7 are respectively fixed through the fixing rings 6 corresponding to the two support frames. The dense mesh safety net 8 is fixed to the steel wire rope 7 and the column screw 1 with a wire tie. The protection system is used to prevent objects and people from falling. By rotating the second nut 5, the height position of the fixing ring 6 relative to the column screw 1 can be adjusted, thereby adjusting the position of the steel wire rope 7.

[0019] The support frame also includes a mountain clip 9, a third nut 10, and a bolt 11. The two ends of the mountain clip 9 are welded to the two sides of the vertical portion of the L-shaped steel bar 2. The third nut 10 is welded to the mountain clip 9. The bolt 11 passes through the mountain clip 9 and is screwed onto the third nut 10. The bottom of the bolt 11 abuts the inner side of the parapet 4. The bolt 11 presses against the inner side of the parapet 4, and the column screw 1 abuts against the outer side of the parapet 4, firmly fixing the support frame to the parapet.

[0020] It also includes an edge alarm 12, which is fixed on one of the column screws 1.

[0021] The distance between the support frames is not less than 2m. The length of the column screw 1 is generally greater than 1.2m.

[0022] The installation process of the present invention is as follows: first, install the support frame, screw the column screw 1 with the first nut 3, adjust it to a suitable cantilever length, place the column screw 1 close to the outside of the parapet 4, and the L-shaped steel bar 2 crosses the parapet 4. Screw the bolt 11 with the third nut 10 and pass it through the mountain-shaped buckle 9 to press against the inside of the parapet 4 to firmly fix the support frame to the upper end of the parapet 4; then use the same steps to install another support frame at a distance of not less than 2m; each column screw 1 is screwed with two of the second nuts 5, and the second nuts 5 are adjusted to the middle and top of the part of the column screw 1 that is higher than the parapet 4, and the wire rope 7 is wound around and fixed on the fixing ring 6, and the dense safety net 8 is fixedly connected to the wire rope 7 and the column screw 1 with a wire tie; finally, the edge alarm 12 is installed to complete the edge protection of the parapet 4.

[0023] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or they are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
