Hollow Core Anchor AN Easy

Application

Internal thread anchor to be used in pre-stressed hollow concrete slabs.
Suitable for suspension of pipe lines, channels, etc. considering the approval regulations for the use with threaded rods or screw. Only to be used with construction components under dry indoor conditions. The general technical approval allows the anchor to be installed even if the drill hole does not hit the cavity.

Installation

Tightening the screw or nut pulls the expansion cone inside the anchor sleeve which keys into the cavity. The anchor spreads Y-shaped inside the hollow space and using the specified torque gives secure form closure.

1)
For edge distances cmin < c ≤ ccr the recommended loads can be determined by linear interpolation.
2)
Using lower strength classes, the value is to be reduced accordingly.
3)
The required screw length is determined by the minimum length of screw + the thickness of the fixture tfix (total length = ls + tfix )
4)
Approved load Fmax / Anchor ≤ Fmax single anchor. On double anchorage with spacing smin < s ≤ scr the recommended load may be determined by linear interpolation, assuming the limiting value s = scr for the double anchorage exposed to tension is twice the recommended load of a single anchor.
