Abstract
An anchor assembly for use in raising tilt-up wall sections which are cast in a horizontal position. The assembly includes an elongated steel anchor member supported in a vertical position on a base. A horizontal steel pin extends through an opening in the lower portion of the anchor member, with the pin and anchor member being retained in the base by two pairs of opposing resilient members which extend partially around the pin. A recess former is positioned over the upper end of the anchor member and is detachably locked to the anchor member by another pair of opposing resilient members which are extendable into a second opening in the upper portion of the anchor member. After the wall section is cast, the recess former is unlocked from the anchor member and removed from the wall section thereby providing access to the second opening of the anchor member. A hoist apparatus is then attached to the anchor member and the wall section is lifted to a vertical position, with the anchor pin preventing the anchor member from being pulled out of the wall section during the lifting process.
