ANCHOR
An anchor includes an anchor body and an insert at least partially within the anchor body. The anchor also includes a coupler body, the coupler body mechanically coupled to the insert, and a coupler nut, the coupler nut coupled to the coupler body.
1 . An anchor for a post-tensioning tendon comprising:
an anchor body;
an insert at least partially within the anchor body;
a coupler body, the coupler body mechanically coupled to the insert; and
a coupler nut, the coupler nut coupled to the coupler body.
2 . The anchor of claim 1 , wherein the coupler body further comprises an anchor coupling flange having coupling features formed thereon and the insert further comprises corresponding coupling features formed thereon for mechanically coupling the coupler body to the insert.
3 . The anchor of claim 2 , wherein the coupling features and corresponding coupling features comprise one or more of a threaded connection or bayonet ramps.
4 . The anchor of claim 1 , wherein the coupler body further comprises an anchor coupling flange having bayonet ramps formed thereon, and the insert further comprises corresponding bayonet ramps formed thereon for mechanically coupling the coupler body to the insert.
5 . The anchor of claim 1 , wherein the coupler body further comprises threads formed on an exterior surface thereof for coupling the coupler body to the coupler nut.
6 . The anchor of claim 1 , further comprising a pocket former, the pocket former positioned about the coupler body.
7 . The anchor of claim 1 , wherein the coupler body is threadedly coupled to the anchor body.
8 . The anchor of claim 1 , wherein the insert is mechanically coupled to the anchor body by press fitting, mechanical welding, chemical welding, friction welding, thermal coupling or welding, electrical welding, optical welding, or beam-energy welding.
9 . The anchor of claim 1 , wherein the insert is formed from a flame resistant material.
10 . The anchor of claim 1 , wherein the insert is formed from metal.
11 . The anchor of claim 1 , wherein the insert is formed from at least one of steel, aluminum, or zinc.
12 . A method of forming a post-tensioned concrete member comprising:
positioning a post-tensioning tendon within a concrete form, the post-tensioning tendon including a tension member, a fixed anchor, and a stressing anchor, the fixed anchor positioned at a first position within the concrete form, the stressing anchor positioned at a second position within the concrete form, the tension member extending between the fixed anchor and the stressing anchor, one or both of the fixed anchor and stressing anchor including:
an anchor body, the anchor body including an insert;
a coupler body; and
a coupler nut;
mechanically coupling the coupler body to the insert;
positioning the coupler body through an end of the concrete form;
threadedly coupling the coupler nut to the coupler body;
placing concrete into the concrete form; and
tensioning the tension member.
13 . The method of claim 12 , further comprising:
removing the coupler nut;
removing the end of the concrete form; and
removing the coupler body from the anchor body.
14 . The method of claim 12 , wherein the coupler body further comprises an anchor coupling flange having coupling features formed thereon and the insert further comprises corresponding coupling features, and wherein mechanically coupling the coupler body to the insert comprises coupling the coupler body to the insert.
15 . The method of claim 14 , wherein the coupling features and corresponding coupling features comprise one or more of a threaded connection or bayonet ramps.
16 . The method of claim 12 , wherein the coupler body further comprises an anchor coupling flange having bayonet ramps formed thereon and the insert further comprises corresponding bayonet ramps, and wherein mechanically coupling the coupler body to the insert comprises engaging the bayonet ramps of the coupler body with the bayonet ramps of the insert.
17 . The method of claim 12 , wherein the insert is formed from a flame resistant material.
18 . The method of claim 12 , wherein the coupler body further comprises threads formed on an exterior surface thereof for coupling the coupler body to the coupler nut.
19 . The method of claim 18 , wherein the threads formed on the exterior surface of the coupler body are one or more of straight threads, tapered threads, continuous threads, discontinuous threads, threads of varying density, threads of varying angles, and threads of varying pitch.
20 . The method of claim 12 , wherein the insert is formed from metal.
21 . The method of claim 12 , wherein the insert is formed from at least one of steel, aluminum, or zinc.
22 . The method of claim 12 , further comprising:
positioning a pocket former about the coupler body before the coupler body is positioned through the end of the concrete form.
