A hoarding for use as a temporary barrier around construction sites comprises two vertical members <B>12</B>, <B>14</B>, a horizontal member <B>16</B> fixed between the vertical members <B>12</B>, <B>14</B> at or adjacent their upper ends and a lower channel member <B>18</B> fixed between the vertical members <B>12</B>, <B>14</B> towards their lower ends. An upper channel member <B>20</B> is located horizontally between the horizontal member <B>16</B> and the lower channel member and extends between the vertical members <B>12</B>, <B>14</B>. The channels of the upper channel member <B>20</B> and the lower channel member <B>18</B> are open towards each other. The upper channel member has an opening at each end through which the vertical members <B>12</B>, <B>14</B> fit allowing the upper channel member <B>20</B> to slide vertically between the lower channel member <B>18</B> and the horizontal member <B>16</B>. Locking means <B>28</B> are provided for locking the upper channel member <B>20</B> in a desired vertical position. An infill panel <B>30</B> may be provided having a lower edge fitted in the lower channel <B>18</B> and an upper edge fitted in the upper channel <B>20</B>. The vertical members <B>12</B>, <B>14</B> and the horizontal member may be formed from a continuous piece of material. The channel members may be of metal. The lower channel may be fixed by welding. The locking means <B>28</B> may comprise components fitting through holes in the vertical members 12, <B>14</B> and in the upper channel member. The infill panel <B>30</B> may be a mesh, wooden or steel panel. Two or more such hoardings may be connected to form a hoarding system using a coupler immediately above the upper channel of each hoarding. |
