ABSTRACT:
A hold-down anchor device for securing reinforcing strands in a mold while the strands are tensioned, the mold filled with concrete, and the concrete allowed to set, is held in place by an anchor means traversing the mold wall. The hold-down anchor device includes a pair of side frame elements which are disposed parallel to each other and positioned generally vertically in the mold. A number of strand hold-down means extend transversely between the side frame elements. A swivel means is pivotally secured to the lower ends of the side frame elements and includes means for engaging the anchor means. The swivel means further includes means for retaining one or more reinforcing strands near the lower ends of the side frame elements in corresponding closely spaced relation with the mold. The swivel means may include either grooves or rollers for retaining the reinforcing strands near the lower ends of the side frame elements.
