<p>Both the posts (1) and the grid units (2) for the fencing are prefabricated from reinforced concrete. Posts are of I-shaped profile cross-section, with profile compartments (3) open upwards. Grid units have upper and lower chords (4, 5), intermediate fence bars (6), and side bars (7) monolithically joined to the chords. The side bars are insertable in the compartments in the posts. There can also be prefabricated reinforced, concrete base components in the form of sleeve foundations, with a sleeve recess (9) shaped to hodl posts. All components are in ready-made reinforced-concrete form, and easily assembled to produce a fence.</p> |
