Installation Data





 Before placing the anchor checks to be made to ensure the strength class of the concrete is not lower than that to which the characteristic loads apply.
 The concrete to be well compacted, e.g. without significant voids.
 Base material temperatures during installation: -5 / + 40 ºC (80 ºC in a short period of time)
 Anchors to be installed ensuring not less than the specified embedment depth, The edge distance and spacing to be kept to the specified values, no minus tolerances to be allowed.
 Drill to the minimum depth and diameter specified, maintaining perpendicular to the surface of the base material. Fixture holes themselves can be used as template.
 When drilling holes, care to be taken not to damage reinforcement in close proximity to the hole position. Action to be taken in the event that drilling is aborted, e.g. due to encountering reinforcement. It is recommended to either install the anchors immediately beside the aborted drill hole, provide that anchoring depth is increased by the depth of the aborted drill hole, or make a new drilling at a minimum distance away of two the depth of the aborted hole. Alternatively, a smaller distance may be chosen, provided the aborted drill hole is filled with high strength mortar. However, unless the aborted drill hole is filled with mortar, it is not permissible a shear or oblique tension load in the direction of the aborted hole.
 Thoroughly clean hole from dust and drilling fragments.
 For holes to be subjected to temperatures below 0 ºC, measures to be taken to avoid the ingress of water into the hole and subsequent risk of local cracking of the concrete due to ice expansion.
 To introduce the anchor into the hole up to the embedment depth through the fixture. A hammer can be use to assure this depth. Do not apply any intermediate lay between the fixture and the washer (sealant, etc.). Apply the specified torque with a torque wrench.
 In case of holes with diameters higher than specified use washers of bigger diameter and thickness, but in this case it is not assured a correct distribution of shear loads amongst all the anchors of a same group. The shear load will be applied on those anchors with the correct diameter on the fixture.
The inviolability of CH Anchors: ACHINB and ACHINN, it is achieved by placing an inviolate zamak star in the screw’s head with a hammer. This zamak alloy star is provided with the anchor in the same box.

Characteristic resistances 


1KN ≈ 100 kg 

* The characteristic resistance of an anchor is that with a 95% probability to be achieved in a tension test. It depends on the mean ultimate resistance, the number of tests and the scatter of the results. 

** Concrete C20/25 per ENV206: characteristic resistance for a specimen ≥ 28 days old:

• Cylindrical sample ø 150 mm. x 300 height ≥ 200 N/mm2

• Cubic sample 150 mm. side ≥ 250 N/mm2

Underline and cursive values correspond to steel failure.

Characteristic resistance for tension and shear must be considered separately.
