Abstract
Abstract A bearing for supporting a roofing tile comprises a base plate which is bushed to receive one end of one or more threaded members. The threaded members comprise bolts with threaded portions of opposite pitch carrying a toothed wheel between the threaded portions. The other end of each threaded member is received in a support plate which is received in a recess in a roofing slab. Each support plate has a fork on one side the lugs of which extends below the base of the support plate. Spacing pins on the base plate separate the roofing slabs and a locking pin on the base plate can be used to turn the toothed wheels and thus tighten or slacken the bolts.
