ABSTRACT:
A simplified anchor for firmly connecting wood or the like to concrete. The anchor includes a pair of connector elements. One element comprises a fluted concrete nail having the usual head and is made of hard metal. The other element comprises a headless pin of soft malleable metal having a notch spaced from but adjacent one end to form a top portion. The tip of the nail is initially overlappingly joined to the notched top portion of the pin by an encircling retaining band. A hole is drilled through the wood and into the concrete to be joined and to a depth equal to the bottom end of the pin below the notch. The pin is inserted into the hole and the nail is then driven into the hole alongside the pin. When the nail head engages the notched top portion of the pin, the pin breaks away at the notch. The nail is then driven further until its head is engaged with the wood surface and the upper pin tip. During driving, the nail cuts into and deforms the pin within the hole in a tightening action.
