<p>The reinforcement for concrete fence posts, produced in a mould, consists of several metal rods (1, 2, 3, 4) parallel to each other and extending in the lengthwise direction of the post. The bars are joined together by at least two metal cross-pieces (6), spaced along them. The cross-pieces (6) have ends (10, 11) which protrude outwards from the polygonal outline of the reinforcement and enable the reinforcement to be positioned correctly inside the mould (16). The outer ends of the protruding sections (10, 11) are preferably situated on a surface which is identical or can be placed on one of the mould surfaces, preferably the inside surface of the mould (16). The cross-pieces (6) are preferably U-shaped with a flat piece in the middle. Alternatively, they may be M shaped.</p> |
