Patent ID: 8518314

Claim:
A method of anchoring an element in a construction object, a surface of which object has pores or structures and/or in which surface pores are creatable by a liquid under hydrostatic pressure and/or in which a cavity is defined, the method comprising the steps of providing a first element and a second element, the first element comprising a thermoplastic material; positioning the first element in a vicinity of said surface and/or of said cavity, respectively, and positioning the second element in contact with the first element; causing a third element to vibrate while loading the first element with a force, thereby applying mechanical vibrations to the first element, and simultaneously loading the first element with a counter-force by the second element; by the joint application of the mechanical vibrations and the load, liquefying at least some of the thermoplastic material, thereby creating liquefied material; causing, by the joint application of the mechanical vibrations and the load from the second and third element, the first element to be compressed and thereby causing the liquefied material to flow into pores and/or structures and/or the cavity; letting the liquefied material re-solidify so that the first element is anchored in the object, and wherein the force in the third element is a tensile force.
