Title (EN) A TENSILE FORCE ABSORBING ANCHORING IN CONCRETE
(FR) ANCRAGE D"ABSORPTION D"UNE FORCE DE TRACTION DANS LE BETON
Abstract: front page image
(EN)For anchoring in concrete, plugs and/or expanders are used, which require relatively deep holes for providing the strength required. In order to reduce the necessary hole depth without deteriorating the strength, and in general to facilitate and render cheaper the anchoring in concrete and other hard material, the present tensile force absorbing anchoring comprises an anchoring member (1) formed integral of music-wire, with an anchoring portion (2) located in a hole in the material, which portion (2) comprises two gripping members (6), each with a free end (7) engaging with the hole wall, which members are formed integral, with each of their two shanks (5) abutting an opposed side of the hole wall against the engaging surface of the free end of the respective gripping member (6) and extending axially out of the hole, which shanks (5) constitute parts of the leg portion of the anchoring member (1) and form and acute angle with the respective gripping member (6), and that each gripping member (6) has a length between its free end and the associated shank which exceeds the hole diameter, and is stiff against bending along its entire length, and that the free end (7) of the respective gripping member (6) prior to the application of the anchoring member (1) in its hole is located at a perpendicular distance from the associated shank (5) which exceeds the hole diameter, for obtaining an initial clamping force at the application of the anchoring member in its hole.
(FR)Dans la realisation d"ancrages effectue dans le beton, des chevilles et/ou des systemes a expansion sont utilises qui necessitent des trous profonds pour obtenir la resistance requise. De maniere a reduire la profondeur necessaire de trou sans diminuer la resistance, et d"une maniere generale pour faciliter et diminuer les couts de l"ancrage dans le beton et dans d"autres materiaux durs, le present ancrage d"absorption de force de traction comprend un organe d"ancrage (1) forme integralement avec du fil metallique musical, avec une portion d"ancrage (2) positionnee dans un trou effectue dans le materiau, laquelle portion (2) comprend deux organes de prehension (6), ayant chacun une extremite libre (7) s"engageant dans la paroi du trou, lesquels organes sont monoblocs, chacune de leurs deux tiges (5) s"appuyant contre une paroi opposee du trou contre la surface d"engagement de l"extremite libre de l"organe respectif de prehension (6) et s"etendant axialement hors du trou, lesquelles tiges (5) constituent des parties de la jambe de l"organe d"ancrage (1) et forment un angle aigu avec l"organe respectif de prehension (6), et chaque organe de prehension (6) possede une longueur entre son extremite libre et la tige associee, laquelle longueur est superieure au diametre du trou, et resiste a la flexion sur toute sa longueur, et l"extremite libre (7) de l"organe respectif de prehension (6) avant le montage de l"organe d"ancrage (1) dans le trou est situee a une certaine distance perpendiculairement a la tige associee (5), laquelle distance est superieure au diametre du trou, de maniere a obtenir une force initiale de fixation lors du montage de l"organe d"ancrage dans le trou.
