Abstract
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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
110 words
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.
Claim 2
Dependent Claim
110 words
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.
Claim 3
Dependent Claim
65 words
The removable press anchor according to claim 1 wherein said anchor body is formed as a pressure member and comprises a plurality of individual rods radially arranged about said traction element, and a distributor head located at the ground-side end of said anchor being removably connected to one end of said traction element, said rods being connected at one end thereof to said distributor head.
Claim 4
Dependent Claim
19 words
The removable press anchor according to claim 2 wherein said rods are provided with surface profilations to increase adhesion.
Claim 5
Dependent Claim
39 words
The removable press anchor according to claim 1 wherein said anchor body is formed as a traction member and comprises a bundle of rods secured at one end thereof to an anchor head releasably connected to said traction element.
Claim 6
Dependent Claim
26 words
The removable press anchor according to claim 4 wherein each of said rods of said bundle extends in an undular form with respect to each other.
Claim 7
Dependent Claim
38 words
The removable press anchor according to claim 5 further comprising spacer elements located in the regions of greatest separation between said rods, and tie cords wound about said rods in the regions of least separation between said rods.
