<p>A hoarding system comprises a hoarding panel extending vertically and having at least one upright post (12) and a foot tie tube (24) extending horizontally, close to the ground and perpendicular to the post, and connected to a lower end of the post. The system may include an antilift mounting device (40) for standing the post on the ground and for mounting one end of the foot tie tube to the post and having means for inhibiting the panel from lifting off the ground. Alternatively or additionally, the system may include a backstay tube (20) adjustably mounted at one end to a point on the upper part (29) of the post, and adjustably mounted at its other end to an adjustable backstay bracket (30) and/or to a point (21) on the foot tie tube (24) so that the backstay tube, the foot tie tube and the post together form a right-angled triangle. In this case the adjustable backstay bracket (30) comprises a base for receiving ballast and seating the foot tie tube on the ground, and is adapted to be mounted at any point along the foot tie tube so as to vary the distance behind the panel at which the ballast is loaded in accordance with the amount of working space behind the hoarding panel.</p> |
