ABSTRACT:
A ground anchor for resisting uplift loads is installed by forming a hole in the earth with an enlargement at the bottom, placing an anchor plate in the bottom of the hole with projectable toggle arms extending out into the hole enlargement and with at least one tension member extending up through the hole from the anchor plate and pouring concrete into the hole to fill at least the enlargement. The toggle arms effectively increase the size of the anchor plate and the effective size of the concrete enlargement so that a larger cone of earth above the anchor plate is utilized for uplift load resistance.
