Abstract
Abstract A reinforcing bar aligner and clamp is herein disclosed. The reinforcing bar aligner and clamp has a square cross-section tubular support arm. A pair of clamps is attached to the tubular arms. Each clamp of said pair is connected to the support arm adjacent an end of the support arm. Each of the clamps is a hinged clamp having an inner right angle jaw and an outer cover jaw. A latch selectively connects the outer cover jaw to the inner right angle jaw. The hinged clamps are adapted to hold a first reinforcing bar in fixed end-to-end proximity to a second reinforcing bar.

Claim 1
Independent Claim
502 words
A reinforcing bar aligner and clamp for holding reinforcing bars substantially vertical during splicing, comprising: a first clamp adapted for releasable connection to a fixed lower reinforcing bar, said first clamp having a first inner V-jaw, a first outer jaw and a first latch selectively connectable between said first inner V-jaw and said first outer jaw, said first inner V-jaw having a first inner jaw plate and a second inner jaw plate formed integral with and perpendicular to said first inner jaw plate, said first outer jaw being rotatable about a pivot toward and away from said first inner V-jaw, said first inner V-jaw and said first outer jaw each having a first shim pin aperture and a first shim slot, said first latch having a first threaded rod having a first rotatable threaded connector connected thereto which is selectively pivotable into engagement with said first outer jaw to hold said lower reinforcing bar in fixed engagement with said first clamp; a first plurality of elongated rectangular removable shims, each elongated rectangular removable shim of said first plurality having a shim pin fitted into one of said first shim pin apertures and a threaded shim connector fitted to one of said first shim slots; a first pair of rectangular mounting plates rigidly connected to said first clamp; a square cross-section elongated support art rigidly connected to said first pair of rectangular mounting plates at a first end; a second pair of rectangular mounting plates rigidly connected to said square cross-section elongated support arm adjacent a second end of said square cross-section elongated support arm; and a second clamp rigidly connected to said second pair of mounting plates, said second clamp having a second inner V-jaw, a second outer jaw and a second latch selectively connectable between said second inner V-jaw and said second outer jaw, said second inner V-jaw having a first inner jaw plate and a second inner jaw plate formed integral with said perpendicular to said first inner jaw plate, said second outer jaw being rotatable about a second pivot toward and away from said second inner V-jaw, said second inner V-jaw and said second outer jaw each having a second shim pin aperture and a second shim slot, said second latch having a second threaded rod having a second rotatable threaded connector connected thereto which is selectively pivotable into engagement with said second outer jaw to hold an upper reinforcing bar substantially vertical in fixed substantially abutting end-to-end proximity with said lower reinforcing bar, said second clamp being identical to, and collinear with, said first clamp, said second clamp being separated from said first clamp by a center-to-center distance greater than 0.05 of a length of the longer of said upper and lower reinforcing bars; and a second plurality of elongated rectangular removable shims, each elongated rectangular removable shim of said second plurality having a shim pin fitted into one of said second shim pin apertures and a threaded shim connector fitted to one of said second shim slots.

A reinforcing bar aligner and clamp for holding reinforcing bars substantially vertical during splicing, comprising: a first clamp adapted for releasable connection to a fixed lower reinforcing bar, said first clamp having a first inner V-jaw, a first outer jaw and a first latch selectively connectable between said first inner V-jaw and said first outer jaw, said first inner V-jaw having a first inner jaw plate and a second inner jaw plate formed integral with and perpendicular to said first inner jaw plate, said first outer jaw being rotatable about a pivot toward and away from said first inner V-jaw, said first inner V-jaw and said first outer jaw each having a first shim pin aperture and a first shim slot, said first latch having a first threaded rod having a first rotatable threaded connector connected thereto which is selectively pivotable into engagement with said first outer jaw to hold said lower reinforcing bar in fixed engagement with said first clamp; a first plurality of elongated rectangular removable shims, each elongated rectangular removable shim of said first plurality having a shim pin fitted into one of said first shim pin apertures and a threaded shim connector fitted to one of said first shim slots; a first pair of rectangular mounting plates rigidly connected to said first clamp; a square cross-section elongated support art rigidly connected to said first pair of rectangular mounting plates at a first end; a second pair of rectangular mounting plates rigidly connected to said square cross-section elongated support arm adjacent a second end of said square cross-section elongated support arm; and a second clamp rigidly connected to said second pair of mounting plates, said second clamp having a second inner V-jaw, a second outer jaw and a second latch selectively connectable between said second inner V-jaw and said second outer jaw, said second inner V-jaw having a first inner jaw plate and a second inner jaw plate formed integral with said perpendicular to said first inner jaw plate, said second outer jaw being rotatable about a second pivot toward and away from said second inner V-jaw, said second inner V-jaw and said second outer jaw each having a second shim pin aperture and a second shim slot, said second latch having a second threaded rod having a second rotatable threaded connector connected thereto which is selectively pivotable into engagement with said second outer jaw to hold an upper reinforcing bar substantially vertical in fixed substantially abutting end-to-end proximity with said lower reinforcing bar, said second clamp being identical to, and collinear with, said first clamp, said second clamp being separated from said first clamp by a center-to-center distance greater than 0.05 of a length of the longer of said upper and lower reinforcing bars; and a second plurality of elongated rectangular removable shims, each elongated rectangular removable shim of said second plurality having a shim pin fitted into one of said second shim pin apertures and a threaded shim connector fitted to one of said second shim slots.
Claim 3
Dependent Claim
86 words
A reinforcing bar aligner and clamp for holding reinforcing bars substantially vertical during splicing as defined in claim 1, in which each of said outer jaws is a unitary plate jaw having a latch slot formed therein, each of said outer jaws being connected to its respective inner V-jaw by a removable connector pin, each of said outer jaws being pivotable about its respective removable connector pin and each threaded rod having a stop positioned adjacent thereto, said stop limiting arcuate travel of said threaded rod.
