Abstract Device for anchoring tensioning elements, such as strands, bundles of metal strands or cables with metal or concrete structures, comprising one or more tensioning elements, a plate for load distribution, the plate being perforated for the passage of said tensioning elements, and clamping means for each of the tensioning elements, according to which there are further provided: a box for receiving all said tensioning elements so as not to contact the box walls, the box being provided with opposite openings of a sufficient size to allow the passage of said tensioning elements; a plurality of tubes of sufficient inner size to accommodate with clearance each of the tensioning elements; a packing of epoxy resin in said tubes and said box about said tensioning elements. Provision is also made for adjustment of the strain by means of a ring nut, as well as interchangeability of the tensioning elements.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
114 words
A device for anchoring a plurality of tensioning strands to a structure, which device comprises: (a) a box encasing intermediate portions of the strands therein; (b) a plate spaced from the box for securing the free ends of the strands and distributing tension loading; (c) corrugated sheaths extending from the plate to the box, each sheath encasing a strand, each sheath being filled with epoxy resin for embedding the strand therein and spacing same from adjacent strands, said sheath being embedded in concrete; (d) the box including a packing of epoxy resin embedding the portions of the strands contained therein and avoiding load peaks in the transition area where strands depart from the box.
