lower ends it will be appreciated that such support beam clips may be used to operatively connect a pair of blocks to a support bracket 534 by positioning the clips so that they span the interface between two adjacent blocks it will also be appreciated that the support beam clip may be longer than a side of a block to which it is operatively connected so that it may operatively connect more than two blocks to a bracket the span 538 of the bracket 534 serves to position the support beam 116 a predetermined distance from a substructure u201c s u201d while the substructure engaging portion 536 serves to attach the bracket 534 onto a substructure u201c s u201d as with the aforementioned embodiment the bracket 534 may be operatively connected to a substructure u201c s u201d using a variety of fastening elements it will be appreciated that the support beam 116 of this embodiment may be used with oppositely facing brackets if desired to form a more robust connection between the wall structure and a substructure u201c s u201d referring now to fig3 and 18 the support beam 116 does not have an extension rather as best shown in fig1 the beam 116 terminates at a first attachment member 512 that includes two spaced apart resilient walls 550 552.
