Abstract
A tie rod assembly for use with forms for forming a wall of pourable, curable material. Each assembly has a rod having opposite threaded ends and two spacers. Each of the spacers has a first conical section having a recessed opening at an apex region of a concave conical guide surface and a hexagonal recess surrounding the apex region, and a second conical section having a threaded bore communicating with the apex opening. The threaded bore has a coil thread nut integrated with the conical second section. The concave conical guide presents a target for directing a remotely inserted bolt towards the apex region for engagement with the coil thread nut.
Claims12
A tie rod assembly for use in assembling at least two opposed wall forms for forming a mold for a wall of pourable, curable material comprising
- a rod having opposite threaded ends, and fastener means for attaching the rod to a first wall form through an aperture therein;
- a nut spacer for attaching to an end of said rod, said nut spacer having a first section having a substantially conical, recessed guide surface for directing a probing rod extending through an aperture in an opposed wall form towards an opening at an apex region of said guide surface, said guide surface presenting a guide opening larger than said apex opening, and a second section axially extending from the first section and having a threaded bore communicating with said apex opening for engaging said rod at an end of the threaded bore opposite the apex opening.
A tie rod assembly for use with wall forms for forming a mold for a wall of pourable, curable material comprising a rod having opposite threaded ends and two spacers threadingly engaging said opposite threaded ends, each of said spacers having
- a first conical section having a recessed opening at an apex region of a concave conical guide surface and a shaped recess near the apex region, and
- a second conical section having a threaded bore communicating with said recessed opening and engaging said rod, said threaded bore comprising a threaded nut integrated with said conical second section.
A spacer for use with a tie rod assembly for use with wall forms for forming a mold for a wall of pourable, curable material, said spacer having a first section having a substantially conical, recessed opening at an apex region of a guide surface and a second section having a threaded bore communicating with said recessed opening, wherein said guide surface directs a remotely inserted threaded rod towards said apex opening for threadingly engaging with said threaded bore.
A wall form assembly for forming a mold for a wall of pourable, curable material, comprising:
- a first wall form having a plurality of apertures therethrough;
- a second wall from, opposed to said first wall form, having corresponding apertures therethrough;
- tie rods, each having opposite threaded ends and fastener means for attaching said rods to said first wall form through said apertures in said first wall form;
- nut spacers for attaching to an end of each said rod, said nut spacers each having a first section having a substantially conical, recessed guide surface for directing a probing rod extending through a corresponding aperture in said second opposed wall form towards an opening at an apex region of said guide surface, said guide surface presenting a guide opening larger than said apex opening, and a second section axially extending from the first section and having a threaded bore communicating with said apex opening for engaging said rod at an end of the threaded bore opposite the apex opening.
