Abstract

Expandable anchor bolt, of the type comprising an elongated cylindrical bolt comprising a wedge-shaped expansion element, whose diameter, initially reduced, increases towards the end of the cusp, substantially up to its main diameter, including expansion devices located at length of a part of the expansion element, substantially inside the periphery of the bolt, being related to each other by a strut passing over said limb of the bolt and forming an integral part of the expansion devices, characterized in that the brace and the expansion devices are made of laminar structure material and have branches whose ends are widened in the form of wings that substantially surround, in the form of a sleeve, the cone-shaped expansion element of the bolt, constituting the front edge areas, tightening and anchoring devices, and its rear interlocking devices they exceed the outer circumference of the bolt and whose lower part is separated from the expansion element of the bolt.
