Key Points
It is essential that all Anchors are installed correctly in accordance with manufacturer’s installation instructions. Basic points to remember are:
- Ensure suitability of anchor for type of substance.
- Assess local factors e.g. proximity to edge, reinforcement etc.
- Use a drill bit in good condition.
- Drill hole to correct diameter and depth.
- Clean out the hole thoroughly - especially critical for chemical bonded anchors.
- Ensure that the correct setting equipment and procedure is used.
- Tighten to correct torques recommended by manufacturers.
Direction of Loading
The most suitable Anchor for the application concerned can be selected after considering the direction of the applied load. The tension and shear values must be less than the safe working loads in the direction concerned. Other factors to be considered are centre to centre distances, centre to edge distances and proximity of reinforcement etc.
Tensile Loads
Common examples of Tensile Load situations include suspension of ductwork and pipework, mechanical services and suspended ceiling applications. These are loads which are applied along the axis of the fixing.
