FIRST SIDE GUTTER ASSEMBLY
After fixing a gutter mitre bracket to the corner of the first
side gutter, lift the gutter into place so the stop end slides
up behind the back channel. Use rivets to fasten the gutter’s
back lip to the roofing at the maximum spacing of one metre
(Figure 9.3). Waterproof the rivets with silicone. Ensure the
front face of the gutter remains vertical and even.
FRONT GUTTER ASSEMBLY
On the front gutter, attach a gutter mitre to the end opposite
the side gutter. Slide the flat end of the gutter straps inside
the rib of the roof sheets every metre. Hang the front gutter
on the gutter straps and using a rolling action, lift the back
of the gutter into the corner mitre of the side gutter. Check
the roof sheets overhang into the gutter by 50mm and the
gutters are square in relation to the framework. Fix the front
gutter with rivets at one metre spacings through the end
of the roof sheets into the gutter’s back lip. For units with
a deck overhang, fix the gutter to the roof sheets with two
rivets per pan. Rivet and seal the front gutter to the mitre and
the gutter straps to the roof sheets. Lift the final side gutter
so that its front end slides into the mitre and the stop end
slides up behind the back channel. Fix the gutter in position
as previously described and waterproof with silicone.
DOWNPIPES
Before attaching the downpipes, rivet the downpipe brackets
to the column. Slide the downpipe over the downpipe outlet
and rivet into position. Rivet the downpipe to the brackets.
Weatherproof all the fasteners with silicone.
FINAL FIXING
FIXING INTO THE CONCRETE FOOTING
Thoroughly check the posts with a spirit level. When plumb,
fill the post hole with approximately 150mm of concrete and
use a shovel or pole to agitate the concrete to remove any air
pockets. Repeat this process until the hole is full, continually
checking the posts as you go. The concrete must have a
slight slope that runs away from the column to ensure any
water does not pool around the base (Figure 10.0). Once the
concrete is set remove any temporary bracing or props.
FIXING ONTO EXISTING CONCRETE
68 OUTBACK COLUMN
If the 68 Outback Columns are to be fixed to an existing
concrete slab with a footing plate, each plate must be fixed
to the concrete with two M12x75 masonry anchors or two
M12x75 screwbolts (Figure 10.1).
