Improvements relating to support assemblies

摘要

An upwardly extending structure is secured to a based support system comprising a series of individual blocks 25 interlocked with a linking beam 26. Each incorporates a groove in its top face which receives the linking beam 26. U-shaped bolts 29A are located in grooves formed in the two sides of the block 25 and running around the base. The ends of the bolts will be fixed to securing plates 29B. Each block has a pair of protrusions and a pair of recesses in both side walls so that the blocks can be interlocked with one another. This reduces the need for all of the blocks to be positively attached to the linking beam 26. Thus, pairs of blocks can be unsecured to the linking beam between two blocks which are positively attached to the beam 26. Attachment plates 32 can be secured to the sides of the linking beam 26. <IMAGE>
