Abstract
A removable press anchor is formed of a tubular sheathing with a traction element carried for longitudinal movement within the sheathing. An anchor body is releasably connected to the traction element and is embedded in a press body which is formed by pressing in hardening material. The anchor body is formed of glass fibers so as to be destructible by cutting forces extending transverse to the longitudinal axis thereof and able to absorb large forces in the direction of its longitudinal length and only small forces in the direction transverse to its longitudinal length. In one embodiment, the anchor body is formed as a pressure member, and in a further embodiment it is formed as a traction member.
Claims6
A removable press anchor comprising a tubular sheathing, a traction element removably carried and arranged for longitudinal movement within said tubular sheathing, and a destructible anchor body releasably connected with said traction element, said anchor body being embedded in a press body formed by pressing in hardening material, said anchor body comprising a head and a plurality of rods connected thereto being formed of glass fibers, whereby said anchor body is destructible by exerting forces extending transverse to the longitudinal axis thereof so as to be capable of absorbing large forces in the direction of its longitudinal length and only small forces in the direction transverse to its longitudinal length.
