The invention discloses a construction fence. The construction fence solves the problem that a traditional fence is complicated in structure, poor in versatility and inconvenient to disassemble and assemble. Every three steel pipes are connected to form a right-angled triangular frame, the connecting ends of the two steel pipes on the horizontal sides and the bevel sides of the right-angled triangular frames are connected in a welded mode, the steel pipes on the vertical sides of the right-angled triangular frames are connected with the other ends of the corresponding two steel pipes through first rotating buckles and second buckles separately; and two steel pipes are adopted as crossbars, the crossbars are fixedly connected with the vertical steel pipes on the two right-angled triangularframes, and binding fixing pieces or fasteners or hooks fixedly connected with a fence panel are fixedly connected with the two crossbars. The first buckles and the second buckles are composed of first hoops and second hoops with the same structure and opposite directions, each hoop is rotatably connected by one end of an inner hoop body and an outer hoop body through a rotating shaft, and the other ends of the inner hoop bodies and the outer hoop bodies are connected by screws and a nuts, and the outer planes of the two inner hoop bodies are opposite to each other and rotatably connected through bearings.
