TOWER FOUNDATION

摘要

A tower foundation (10) has a base slab (11), pillar slabs (12), and a crown stab (13), all of which are made of precast concrete structures. The slabs are all retained in position by steel guide rods (15) that extend upwardly from the base slab. The guide rods have externally threaded ends (16) configured to receive internally threaded mounting nuts (17). The crown slab has guide rod mounting holes (22) through which the guide rods extend. The crown slab also has compression washer assemblies (25) which include a pressure plate (26) and anchor legs (27). The pressure washer has a central mounting hole (28) coaxially aligned with the crown slab guide rod mounting holes. The pressure washer has a top surface (29) which is flush with the crown slab top surface (30). The mounting nuts bear against the pressure washer and not against the concrete.

主权项

1. A tower foundation slab for a tower having guide rod mounting nuts adapted to mate with guide rods coupled to said tower foundation slab comprising:
a concrete body portion having a top surface, a bottom surface opposite said top surface, and a plurality of guide rod mounting holes extending vertically between said bottom surface and said top surface, and a plurality of horizontally oriented metal pressure plates partially embedded within said body portion such that each said pressure plate has a top surface which is positioned so that said pressure plate top surface is generally flush with said body portion top surface and configured to contact a threaded mounting nut coupled to a guide rod extending through said concrete body portion guide rod mounting hole, each said pressure plate having a vertically extending guide rod mounting hole therethrough configured to receive a guide rod therethrough, each said pressure plate guide rod mounting hole being coaxially aligned with one said body portion guide rod mounting hole.
