<p>Two panel edges 1, 2 are joined by a series of brackets 3 on each of the panels protruding beyond the edge which is to be joined to the other panel. Each bracket has a main body generally parallel locally to the plane of the panel and an upstanding flange 11 on its free end, facing away from the plane of the panel, the brackets being arranged so that when the two edges are pushed together the two series of brackets on the two panels interleave. The panels can then be held together by passing a bar down the channel formed by the flanges 11, or by encasing the flanges in concrete 22, or both. The method can be used for instance to repair a corroded post such as a lamp post, by applying sleeve sections around the posts, joining them and filling the annular gap with concrete. <IMAGE></p> |
