Abstract
An apparatus may include a bracket having a post-tensioned cable tunnel and a pair of tabs configured to receive a post-tensioned cable and to prevent rotation of the bracket relative to the post-tensioned cable. An apparatus may include a plasma torch attachment member configured to releasably engage with the head of a plasma cutting torch of the type having a plasma cutting tip attached thereto, and to rotatably attach to the bracket such that the plasma cutting tip may be moved in an arc relative to the post-tensioned cable.
Claims18
A plasma torch attachment device comprising:
- a bracket comprising a proximal end and a distal end;
- wherein the proximal end comprises a plasma torch attachment member to engage with a plasma torch cutting head;
- and
- wherein the distal end comprises a releasably engageable positioning device to releasably hold a cable to be cut.
An apparatus for positioning a plasma cutting torch to cut off a free end of a post-tensioned cable embedded in a concrete body, said apparatus comprising:
- a bracket having a post-tensioned cable tunnel and a pair of tabs configured to receive the post-tensioned cable and to prevent rotation of the bracket relative to the post-tensioned cable;
- and
- a plasma torch attachment member configured to:
- releasably engage with a head of a plasma cutting torch of the type having a plasma cutting tip attached thereto;
- and
- rotatably attach to the bracket such that the plasma cutting tip may be moved in an arc relative to the post-tensioned cable.
A method for cutting a tensioned cable comprising:
- attaching a proximal end of a bracket to a plasma torch cutting head and attaching a distal end of a bracket to the tensioned cable to be cut;
- and
- cutting the tensioned cable with the plasma torch cutting head;
- wherein the proximal end of the bracket comprisesa plasma torch attachment member to engage with the plasma torch cutting head;
- and
- wherein the distal end of the bracket comprises a releasably engageable positioning device to releasably hold the tensioned cable to be cut.
A method for utilizing a plasma cutting torch to cut off a free end of a post-tensioned cable embedded in a concrete structure, said method comprising:
- pushing a plasma cutting apparatus onto the post-tensioned cable, the plasma cutting apparatus comprising:
- a bracket having a post-tensioned cable tunnel and a pair of tabs configured to receive the post-tensioned cable and to prevent rotation of the bracket relative to the post-tensioned cable;
- and
- a plasma torch attachment member configured to releasably engage with a head of a plasma cutting torch of the type having a plasma cutting tip attached thereto and rotatably attach to the bracket such that the plasma cutting tip may be moved in an arc relative to the post-tensioned cable;
- positioning the bracket along a longitudinal axis of the post-tensioned cable, such positioning defining a cutting point on the post-tensioned cable;
- and
- rotating the plasma cutting torch as the torch is engaged to cut a full diameter of the post-tensioned cable.
