TOWER FOUNDATION GUIDE ROD NUT

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 lower ends (16) configured, to receive internally threaded guide rod mounting nuts (17) which have a metal mounting plate (20) with a guide rod hole (21) therethrough, a main body portion (22) welded to the mounting plate and having a threaded channel (23) therethrough, and a sealing plate (24) coupled to bottom of the main body portion through a peripheral weld (25) so as to seal the bottom opening of the threaded channel.
