  • Concrete anchor and method of attaching elements to concrete slabs
    Patent number: 4945704
    Abstract: A cup-shaped anchor is provided which has a large pullout resistance because it translates vertical pullout force placed on the anchor into lateral stress within the concrete slab. Preferably, the anchor is frustoconical and provided with two pairs of oppositely aligned holes located in the walls of the anchor which slant generally outwardly from its base. Bracing bars are preferably inserted through the holes to both reinforce the concrete slab and further increase the pullout resistance of the anchor. Preferably the bracing bars are separate, electrically non-conducting bars to electrically isolate the anchor and support members. The anchor permits elements to be attached to a face of a concrete slab by means of a threaded hole which is sealed against concrete entering during pouring.
