Flange Plate

Flange Plate Installation Method

1. Excavate as per recommended area and depth.
2. Shutter off top edge level and place ducting - ensure that all shuttering is supported.
3.Assemble bolts through template and screw nuts on so that recommended thread is protruding through template to give the relevant 'P' dimension when bolts are set in foundation, as noted in table.
4. If using bolt frame, ensure that the nut below the top template will be clear of the finished concrete surface level when the 'P' dimension is achieved.
5. For bolt frame method, position the assembled bolt frame in place within foundation pit, using cross slats to bridge pit and position service ducting so that a minimum of 50mm of duct will be proud of the finished concrete surface level.
6. Pour concrete level with top of shuttering, tamp down and level surface.
7. For bolt frame method, use a vibrating poker whilst pouring concrete to ensure no air traps around bolt frame lower locating plate.
8. For template method, push bolts down into concrete so that template is flat on concrete and nuts are against template with bolts vertical. Ensure that cable duct end is through entry hole in template and protrudes by 50mm min.
9. Allow 72 hours for concrete to cure before placing pole/column
10. Remove template before placing pole. Note: Where back nuts are used to level pole/column it is essential that a load bearing grout is used to fill the void between base plate and concrete. Failure to do this may cause excessive deflection in pole.

Embedded Base

Embedded base installation method

1. Excavate as per recommended area and depth
2. Set socket into excavated pit on 2no 1 inch thick slabs or suitable hardcore
3. Ensure socket verticality and that it is supported centrally.
4. Position service duct so that 100mm enters the socket, ensuring correct orientation with service entry point on pole.
5. Pour concrete on the outside of the pipe and fill pit to just below the top level of the socket.
6. Allow to cure for minimum of 72 hours
7. Lower pole into socket and support in position for operations 8-11
8. Fill hardcore and sand around the base of the pole to a depth of approx 150mm
9. Pack this down so that it is well compressed
10. Select timber wedges and wedge pole in 3 places ensuring pole is vertical
11. For poles up to 7 metres in height pour concrete into open socket. For poles over 7 metres in height use a cementitious grout instead of concrete. Use a vibrating poker to ensure no voids or air traps.
12. Allow 72 hours to cure
13. Remove wedges and fill gaps with grout
