<p>There is described a structural bearing including a bottom bearing plate and a top bearing plate. Sliding surfaces in mutual sliding contact are fixed against horizontal movement relative to the bottom bearing plate and the top bearing plate respectively. One of the bearing plates is provided with one or more spigots engaging in slots in the other bearing plate, the spigot or spigots substantially preventing relative rotation of the bearing plates about a vertical axis and substantially preventing relative horizontal movement of the plates in one direction but allowing relative horizontal movement of the plate in a direction normal thereto.</p> |
