PCT No. PCT/SE80/00248 Sec. 371 Date Jun. 10, 1981 Sec. 102(e) Date Jun. 10, 1981 PCT Filed Oct. 10, 1980 PCT Pub. No. WO81/01036 PCT Pub. Date Apr. 16, 1981.At 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 formed integral of steel wire, with an anchoring portion located in a hole in the material, which portion comprises two gripping members, each with a free end engaging with the hole wall. The members are formed integral, with each of their two shanks abutting an opposed side of the hole wall against the engaging surface of the free end of the respective gripping member and extending axially out of the hole. The shanks constitute parts of the leg portion of the anchoring member and form an acute angle with the respective gripping member, and each gripping member 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. The free end of the respective gripping member prior to the application of the anchoring member in its hole is located at a perpendicular distance from the associated shank which exceeds the hole diameter, for obtaining an inital clamping force at the application of the anchoring member in its hole. |
