Injection anchors are produced using a cold rolled thread which not only enhances the strength of the bar, but also provides a self cleaning, robust thread which is easy to use on construction sites. The ISO standard rope thread, which is continuous along the length of the bar, permits site cutting of the bar without the need for special tools or dressing procedures, whilst also fitting the majority of rock drilling machines.
The bond of the injection anchor is in accordance with BS 8110 and BS 6744, the continuous thread provides a key for the grout.
Stainless steel injection anchors can be supplied with a range of accessories, which can be manufactured to meet individual contract requirements.
The selection of any drill bit is based on experience, but a trialanchor must be satisfactorily tested before the project is finally commenced.
SACRIFICIAL DRILL BITS
Drill bits to suit all applications and ground conditions.
Available in ductile iron or fabricated to customers specific requirements. Please see Pattress Plates Data sheet.
Manufactured either flat which can take up to 8 degree misalignments or dished to suit up to 45 degree misalignment. Can be supplied with a hemi nut or washer to suit.
Allows a small diameter bar to be used with a larger pattress or washer plate.
COUPLERS / NUTS
Load nuts and couplers have been designed to provide a strength of anchorage equal to the theoretical minimum required by the threaded bar. Lock nuts are for locking purpose only
To be fitted to the end of the bar for passing rock netting wire through and many other uses.
