rotation stops 48 and could be formed or positioned on the upper surface 12 of support plate 10 at any location of choice but preferably they would be centrally located so that the upper threaded end 52 of anchor bolt 40 would extend upwardly in a uniform location and orientation as multiple anchor bolts would be used to secure a sill plate fig9 is a cross sectional side view of support plate 10 with anchor bolt 40 positioned thereon being positioned between foundation blocks the foundation blocks 60 are secured to a footing by mortar or cement they are positioned in rows atop one another and the adjacent upper block is normally staggered with respect to the two blocks below it such that the upper block sits evenly divided on the seam between the two adjacent lower blocks in fig9 lower blocks 60 a and 60 b are topped by an upper block 60 c shown in cross section prior to positioning block 60 c a support plate 10 would have been positioned atop block 60 a such that edges 16 18 20 and 22 of support plate 10 would be sandwiched between block 60 a and block 60 c when it is positioned atop block 60 a and 60 b and secured by mortar or cement 61 in the preferred embodiment support plate would have a plurality of perforations 11 proximate its peripheral edges 16 18 20 and 22 this would further assist in stabilizing the support plate and the resultant anchor bolt in that as mortar would be applied to the tops.
