Anchoring, splicing and tensioning elongated reinforcement members

An anchor system comprising:

• a front-end surface configured to face a static structure;
• at least one bore extending in an axial direction and generally perpendicular to said front end surface;
• a clamp side surface having a plurality of clamping holes formed therein, said plurality of clamping holes being formed to extend such that said plurality of clamping holes are substantially parallel to said front-end surface;
• a plurality of axial slits extending from said front-end surface to said at least one bore, said plurality of axial slits including at least an intermediate slit and two external slits, said plurality of axial slits forming at least two clamping members;
• a plurality of fasteners positioned in said clamping holes and adapted to clamp said at least two clamping members together, wherein clamping said at least two clamping members together contracts said at least one bore, and wherein said plurality of fasteners are offset from said front-end surface such that as said plurality of fasteners are clamped to said at least two clamping members, a taper is formed wherein said bore and said axial slit are larger at said front-end surface and decrease in size towards a back-end surface;
• a first elongated reinforcement member inserted within said at least one bore, said first elongated reinforcement member having a first end;
• and
• a second elongated reinforcement member inserted within said at least one bore, said second elongated reinforcement member being at least parallel to said first elongated member,
• wherein said plurality of fasteners exert a clamping force on said at least two clamping members to secure both of said first and second elongated reinforcement members within said at least one bore.

Au anchor system for imparting a compressive stress into a static structure, comprising:

• a front-end surface configured to lace a static structure;
• at least one bore extending in an axial direction and generally perpendicula to said front-end surface, wherein said bore has a tapered opening proximate said front-end surface, said tapered opening decreasing in size from said front-end surface;
• a fibre reinforced polymer (FRP) rod disposed within said at least one bore;
• a clamp side surface having a plurality of clamping holes formed therein, said plurality of clamping holes including at least four openings equally spaced along an axial length of the anchor system and being formed to extend such that said plurality of clamping holes are substantially parallel to said front-end surface;
• a plurality of axial slits extending from said front-end surface to said at least one bore, said plurality of axial slits including at least an intermediate slit and two external slits, said plurality of axial slits forming at least two clamping members;
• and
• a plurality of fasteners including at least four substantially identical fasteners positioned in said clamping holes and adapted to clamp said at least two clamping members together, wherein clamping said at least two clamping members together contracts said at least one bore.
