  • Patent number: 8567151
    Abstract: A device for connecting an exterior deck structure to a contiguous building via a bore-hole through the deck ledger and building header retains the deck in place in the event of earthquake or similar stresses. A pair of tension members comprising interlocked tensile links, are encapsulated in a generally cylindrical plastic plug to maintain ½ to 2 inches separation, to provide a thermal barrier. A pivoting toggle pin on the end of one link pivots between a first position aligned with the axis of the link and a second position transverse to the axis. The plastic plug may have an extending lip supporting the pivot pin in axially alignment. The second link may be rigid or flexible, has a sealing member adapted to slide thereon to seal the bore-hole. The second link is adapted to be fastened securely to a joist or other appropriate member of the deck.

  • Patent number: 8555597
    Abstract: A connector device for connecting an exterior deck structure to a contiguous building the connector having a pair of interlocked non-contacting cable loops, with a plastic plug encapsulating the interlocked ends of the cables and separating the cables to act as a thermal barrier. An expanded head at one end of the plug, with associated foam washer seals against a deck header. The exterior cable end of the connector is attached to a deck joist and the interior end of the connector is attached to a building joist, wherein the respective joists may be laterally offset. The connector prevents detachment of the deck from the building during severe tectonic of weather activities.
