[0020] Please refer to Figures 1 to 5, the present utility model provides a technical solution: a safety fence for construction, including three base plates 1. A plurality of guardrail bars 2 are fixed on the top surface of the base plate 1. Assembly columns 7 are fixed at both ends of the top surface of the base plate 1. Warning reflective stickers 5 are fixed on both sides of the base plate 1. The tops of the plurality of guardrail bars 2 are fixed to the bottom surface of the connecting rod 3. The two ends of the connecting rod 3 are respectively fixed to the tops of the two assembly columns 7; a threaded semi-cylinder 8 is fixed to the top of the connecting rod 3. Two adjacent base plates 1 are hinged by a hinge 6. The threaded semi-cylinders 8 at the ends of the two base plates 1 are assembled into a stud, and a nut 9 is sleeved and screwed on the stud; two identification plates 4 are provided above the base plate 1. The two identification plates 4 are symmetrically distributed with respect to the guardrail bars 2, and the identification plates 4 are fixed on the surfaces of the plurality of guardrail bars 2; the threads of the two threaded semi-cylinders 8 on both sides of the base plate 1 are connected.

[0021] When three base plates 1 need to be placed side by side, arrange the three base plates 1 in a row, and then sleeve and screw the nut 9 on the threaded semi-cylinders 8 above two adjacent base plates 1, so as to realize the anti-bending limit of two adjacent base plates 1; when three base plates 1 need to be placed in a "匚" shape, unscrew the nut 9 from the threaded semi-cylinder 8, and then move the two side base plates 1 to make the three base plates 1 in a "匚" shape.

[0022] A fixing bracket 10 is sleeved at one end of the base plate 1. The fixing bracket 10 is connected to the base plate 1 by a bolt 12. The fixing bracket 10 is in an "L" - shaped plate structure.
