- Screws or threaded rods can be used
- The anchor can also be mounted outside the cavity axis, up to 50 mm from the prestressed strand – maximum flexibility
- Quick, easy installation – no special tool required
- Immediate load-bearing capacity – no waiting
- DIBt National technical approval Z-21.1-1832
- Fire resistance (base material: concrete C45/55 or C50/60): R30, R60, R90, R120: DIBt National technical approval Z-21.1-1832, fire protection test report no. (3526/3426)
- The cone is separated from the expansion sleeve when the screw or hexagon nut is tightened. - Important: At least three screw/nut rotations are required. Applying the installation torque pulls the cone into the expansion sleeve and expands it
- Anchoring is only permissible in hollow-core prestressed concrete ceilings with a hollow space width that does not exceed 4.2 times the web width (bH <= 4.2 x bSt)
Key:
tfi x = thickness of the attachment
du = mirror thickness
bH = cavity width
bSt = web width
sSp = axis distance to pre-stressed strand
c = edge distance
Tinst = installation torque
