<p>The hinge (1) has a square shaped section (2) presenting pawls (4, 5), regularly distributed along walls (9, 11) of a core (3), where the hinge is manufactured by pressing. An anchoring unit is anchored in a ground, and each of the pawls maintains a network of wires. The pawls form clamps turned towards a lower end (6) of the hinge. The pawls (4) of an upper part (7) of the hinge are anchored with a grid, while the pawls (5) of a lower part (8) of the hinge are intended to be inserted in the ground since the pawls (5) contribute to increase the resistance at the wrenching of the hinge.</p> |
