Abstract
A fastener for a high strength connection with a substructure with a straddling dowel, drilling cylinder or nail for insertion into a substructure material, for example, of concrete, rock, wood or the like, is disclosed. At least a portion of an outer surface of the fastener means is coated with a curable adhesive.
Claims15
An expandible dowel for insertion into a hole drilled within a substructure, comprising:
- a body member;
- a radially expandible member disposed upon said body member;
- means operatively connected to said body member and movable relative to said body member and said radially expandible member for causing said radially expandible member to be radially expanded into contact with interior wall portions of a substructure, which define a hole into which said expandible dowel is to be inserted, when said means is moved relative to said body member and said radially expandible member;
- and
- coating means comprising a curable adhesive disposed upon an outer peripheral surface portion of said radially expandible member for adhesively bonding said expandible dowel within a hole defined within a substructure into which said expandible dowel is to be inserted.

An expandible dowel for insertion into a hole drilled within a substructure, comprising:
- a threaded shaft member having a longitudinal axis;
- a radially expandible sleeve member disposed upon said body member;
- an expansion cone member threadedly engaged with said threaded shaft member, and having a portion thereof interposed between said threaded shaft member and said radially expandible sleeve member, so as to undergo axial movement relative to said threaded shaft member, and thereby cause radially outward expansion of said radially expandible sleeve member into contact with interior wall portions of a substructure which define a hole into which said expandible dowel is to be inserted, when said threaded shaft member is rotated relative to said expansion cone;
- and
- coating means comprising a curable adhesive disposed upon an outer peripheral surface portion of said radially expandible sleeve member for adhesively bonding said expandible dowel within a hole, defined within a substructure into which said expandible dowel is to be inserted, when said expandible sleeve member is expanded radially outwardly into contact with the interior wall portions of the substructure by said expansion cone member.
