ABSTRACT:
An adjustable brick support ring (10) formed from a plurality of arcuate ring segments (16, 18) that are pivotally connected to each other in endwise fashion. Each ring segment includes a mating end (40) that is received between two connecting plates (36) that are secured on either side of an engaging end (38) of an adjacent ring segment and project therefrom. A pivot pin (56) is installed through aligned holes in the connecting plates and the overlapped mating end of the ring segment to enable adjacent segments to pivot with respect to each other for adjustment of the size of the arcuate ring. A locking pin (62) is inserted through a selected one of a sequence of locking holes (60) formed in the locking plate at a point radially inwards from the pivot pin, to pass through aligned locking holes (58) formed in the overlapped mating end of the ring segment to prevent rotation of the segments with respect to each other from an adjusted size. The ring is mounted on a slide rail assembly (72) to slide along the length of an adjustable scaffold (12).
