Abstract

Abstract A method of installing form-tie rods in a pair of substantially aligned holes in an opposed pair of spaced-apart concrete forms is disclosed to comprise the steps of inserting and visually aligning a hollow or tubular member in said holes, then the step of withdrawing the tubular member from the holes in one direction or the other while the tubular member leads or guides a form-tie through the holes.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 115 words
The method of installing a form-tie in substantially aligned holes in facing, spaced-apart form panels comprising the steps of: introducing a straight, open ended, internally unobstructed, tubular member through a first of said holes from its outer end and passing the same across the space between said forms; sighting through said tubular member toward the inner end of the second of said holes and aligning the tubular member therewith; inserting said tubular member into the second hole; introducing a form-tie into an end of the tubular member; and applying pressure on said form-tie to cause movement of said tubular member and the following of said form-tie across said space and into and through said holes.
Claim 2
Independent Claim 115 words
The method of installing a form-tie in substantially aligned holes in facing, spaced-apart form panels comprising the steps of: introducing a straight, open ended, internally unobstructed, tubular member through a first of said holes from its outer end and passing the same across the space between said forms; sighting through said tubular member toward the inner end of the second of said holes and aligning the tubular member therewith; inserting said tubular member into the second hole; introducing a form-tie into an end of the tubular member; and applying pressure on said form-tie to cause movement of said tubular member and the following of said form-tie across said space and into and through said holes.
Claim 3
Dependent Claim 32 words
The method of claim 1 in which the form-tie is inserted into the tubular member from a direction opposite the direction of insertion of the tubular member and the latter is withdrawn.
Claim 4
Dependent Claim 39 words
The method of claim 1 in which the form-tie is inserted into the tubular member in the same direction as the tubular member was inserted and the latter is passed on through said holes leading the form-tie into place.
