6. Setting up the wire saw system
6.1 Through-holes for the diamond wire
– Plan the working procedure carefully and precisely before beginning to install the system and before drilling the
through-holes.
– Drill the through-holes for the diamond wire (see fig. 6.1, no.
).
Use a suitable drilling machine, depending on the situation and the base material:
킞
Combihammer TE 70 with 16 mm dia. drill bit
킞
Diamond drilling machine DD 200 with the core bit DD-BS 52
6.2 Fastening to the base material
WARNING
Use an anchor suitable for the material on which you are working and observe the anchor manufactu-
rer’s instructions.
NOTE
Hilti M12 metal expansion anchors are usually suitable for fastening diamond core drilling equipment
to uncracked concrete. Under certain conditions it may be necessary to use an alternative fastening
method. Please contact Hilti Technical Service if you have any questions about secure fastening.
– Rigid and secure fastenings are the basic prerequisite for efficient and safe sawing. We recommend the use of
Hilti drilling and anchoring systems.
– Fasteners suitable for the base material in question should be used to fasten the rail supports and single-pair
pulley stands. For example, a minimum edge distance of 18 cm must be observed when setting the Hilti HKD
M12 metal expansion anchor. As a general rule, this anchor should be set
≥
5 mm below the surface of the con-
crete. After drilling the hole, the dust should be blown out.
– Hilti HIT adhesive anchors can be used in masonry etc. or, alternatively, through-holes drilled and threaded rods
used.
6.3 Recommended fastening method using the clamping spindle and clamping nut
For fastening the rail supports and single-pair pulley stands, Hilti recommends use of the HKD-D anchor in con-
junction with the double-thread clamping spindle and clamping nut with pivoting baseplate.
Advantages
1. Flexible clamping nut / baseplate provides secure fastening even on uneven surfaces and when anchor holes
are drilled at an angle.
2. Coarse thread pitch for rapid assembly and disassembly
3. The anchor can be set deeper.
