13 are formed by pouring concrete into the holes the base plates 15 are then embedded in the concrete of piers 13 such that the top of base plate 15 is flush with surface of the concrete anchor bolts 17 are connected to base plates 15 and extend into the concrete a distance below base plate 15 a plurality of supporting members or supporting pipes 19 are positioned such that a first end portion of each supporting pipe 19 rests on a corresponding base plate 15 supporting pipes 19 extend upwardly a selected distance from each base plate 15 the length of supporting pipes 19 can be varied to accommodate various desired slab 11 heights referring to fig3 a support sleeve 21 with a greater diameter than supporting pipe 19 and cut with a length equal to the desired thickness of the concrete slab 11 is constructed so that it may slide over supporting pipe 19 the inner surface 23 of sleeve 21 has threads 25 formed therein and extending along a length of sleeve 21 reinforcing bars rebar 27 are connected to the outer surface of sleeve 21 in this embodiment a first portion 29 of rebar 27 is welded to sleeve 21 vertically along the length of sleeve 21 a second portion 31 of rebar 27 is connected to and extends outwardly and downwardly at an angle from first portion 29 of rebar 27 a third portion 33 of rebar 27 is substantially perpendicular to support sleeve 21 and extends between first portion 29 and second portion 31 of rebar 27 rebar 27 is welded around the outer peripheries of sleeve 21 at 60 degree intervals two nuts 35 offset from rebar 27 are welded to opposite.
