[0027] The technical solutions of the present utility model will be described in detail below with reference to the drawings and embodiments.

[0028] Embodiment

[0029] Provide a quick-assembly safety railing for the edge of a cantilever slab, and the installation schematic diagram is as Figure 1 shown Figure 2 is Figure 1 the enlarged view of the safety railing for the quick assembly of the edge of the cantilever slab in

[0030] Among them, the vertical rod main body module 7 is an inverted F shape, including a vertical column 1, an upper horizontal rod 2 and a lower horizontal rod 3. The lower horizontal rod 3 is fixedly welded to the end of the vertical column 1. The upper horizontal rod 2 is connected to the vertical column 1 through a first bolt 4 and is parallel to the lower horizontal rod 3. By tightening the second bolt 5 on the upper horizontal rod 2, the upper horizontal rod 2 and the lower horizontal rod 3 are fixed on the edge of the concrete slab, and then the vertical column 1 is fixed on the concrete slab;

[0031] A vertical column connector 6 is arranged on the vertical column 1 and is installed and fixed with the railing 8.

[0032] As Figure 3 shown is the installation top view of the safety railing for the quick assembly of the edge of the cantilever slab, Figure 4 is the schematic diagram of the railing.

[0033] The lower horizontal rod 3, the vertical column 1, the upper horizontal rod 2 (the screw hole has threads), the bolt, the bolt with threads. Specifically as follows:

[0034] Railing vertical column: Use a steel pipe vertical column (or use square steel, etc.), and set 1 vertical column 1 every 2 - 3m. The vertical column 1 is firmly welded and connected to the lower horizontal rod 3 and is connected to the upper horizontal rod 2 through a first bolt 4 to form a fixed railing vertical column main body; the total height of the vertical column 1 is about 1.55m (to ensure the height of the edge railing is 1.2m). It should be noted that this is only for illustration and can be adjusted according to the specific height of the edge railing, without limitation.

[0035] Lower horizontal rod 3: The horizontal support uses a steel pipe (or uses square steel), the length of the horizontal rod is 300 - 500mm, and is firmly welded to the vertical column 1;

[0036] Upper horizontal rod 2: Use a steel pipe (or square steel), the length of the horizontal rod is 300 - 500mm; a vertical fixing piece is welded at the end of the upper horizontal rod 2 and is fixed firmly with the vertical column 1 by 2 bolts (the height of the upper horizontal rod can be adjusted according to the thickness of the slab). Two threaded screw holes are arranged on the upper horizontal rod 2, and two long bolts, that is, the second bolt 5, are inserted. After the vertical rod main body module 7 is placed at the edge of the slab, the second bolt 5 is tightened to fix the upper horizontal rod 2, the lower horizontal rod 3 and the vertical column 1 on the concrete slab to play a fixing role.
