Title: Anchor bolt assembly

Abstract: An anchor bolt assembly for supporting an anchor bolt to be embedded in a concrete structure is disclosed. In a first embodiment, the assembly includes a cup-shaped washer which is threadedly mated with the anchor bolt. A concrete form is provided with a through-bore through which the free end of the bolt passes while the washer is disposed in abutting contact with one surface of the form. Nails are driven through the washer and into the form so as to secure the washer-bolt assemblage to the form. Nuts may be threadedly mated upon both ends of the bolt in order to provide rigidifying forces to the assembly and additional anchor retaining forces for the bolt when the latter is embedded in the concrete. The assembly may be utilized in forming concrete ceilings, floors, walls, or columns. In a second embodiment, two washers are employed. The washers are disposed upon opposite surfaces of the concrete form and in conjunction with one of the washers, locator pins or spikes are provided in order to pre-locate the washer relative to the form through-bore so as to facilitate assemblage of the anchor bolt assembly. The dual washer assembly also readily facilitates the repetitive formation of the concrete ceilings, floors, walls, or columns.
