  • Patent number: 3974603
    Abstract: For a poured concrete basement wall, horizontally spaced rectangular plates are secured to the inner face of the outer wall form in parallel spaced relationship thereto. The inner wall form is then space from the inner face of the plates. Temporary fasteners are inserted through the outer wall form and secured to the plates and shielded from concrete which is then poured into the space between the forms. After setting, the fasteners are removed, the forms removed, and long rods having L-shaped ends remote from the wall are disposed in trenches directed outwardly from the wall, the inner ends being secured to the plates replacing the fasteners. The L-shaped ends are set in concrete poured in the ground and serve as anchors. The rods, anchors, and trenches are then covered up with backfill against the wall.
