Abstract
Abstract The present invention relates to improvements in the system of fixing braided cables and rods subjected to stress, which essentially consist in a truncated-conic crown of adequate thickness whose contour includes regularly spaced and sensibly semicircular recesses each of which is aimed to have housed therein the corresponding braided cable. Radially disposed and in front of the said recesses the same crown, but by its inner contour, includes triangular grooves weakening by that part the cross section of the crown in order to allow a deformation thereof permitting it to have a close adaptation to the necessary form and to obtain a retention pressure being practically uniform for all the cables.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
113 words
An anchor for tension members subjected to tensile stress comprising: an external ring having a conical inner surface; an internal wedging crown having an inner surface and an outer surface, said outer surface having a truncated-conical configuration conforming with said conical inner surface of said ring and having longitudinal recesses therein for receiving said tension members, said inner surface of said crown having longitudinal deformation grooves therein to allow said crown to deform sufficiently to conform said recesses to said tension members when subjected to said stresses, whereby said tension members are held between said external ring and said internal crown by radial wedging stresses and tangential stresses resulting from said tensile stress.
Claim 2
Dependent Claim
113 words
An anchor for tension members subjected to tensile stress comprising: an external ring having a conical inner surface; an internal wedging crown having an inner surface and an outer surface, said outer surface having a truncated-conical configuration conforming with said conical inner surface of said ring and having longitudinal recesses therein for receiving said tension members, said inner surface of said crown having longitudinal deformation grooves therein to allow said crown to deform sufficiently to conform said recesses to said tension members when subjected to said stresses, whereby said tension members are held between said external ring and said internal crown by radial wedging stresses and tangential stresses resulting from said tensile stress.
Claim 3
Dependent Claim
24 words
The anchor as claimed in claim 1 wherein said deformation grooves are of triangular cross-section and are disposed in radial alignment with said recesses.
