Initially the bracket T piece shall be fixed to the bracket arm with
two M12 cup head bolts (hand tighten only), a spring washer is to be
located between the standard M12 washer and nut (Figure 4). Mark
the position of the bracket on the fascia and notch a rectangular
hole in the fascia allowing the bracket to be fed through the front
of the fascia.
The hole may need to be enlarged slightly if the M12 cup head
bolts interfere with the fascia. Insert the bracket through the fascia
and fix with the channel to the house rafter using M12 hex head
bolts through the existing holes in the bracket and further up the
channel (Figure 6). Adjust the T piece so it is horizontal and has
the appropriate extension past the fascia to allow for fixing of the
attachment beam. T piece connection bolts are to be tightened to a
minimum 50Nm torque.
Fix the bracket as close to the base of the gutter as possible
(recommended minimum distance 10mm from lowest end of gutter),
as shown in (Figure 50).
The 150 attachment beam is fixed to the end plate to ensure the
carport roof sheets drain into the existing house gutter (Figure 5).
After fixing all the brackets and channels, the 150 attachment beam
is fixed in place.
Prop up the 150 attachment beam in position with the double flange
on top, the beam will need to be located at a height on the bracket
which allows clearance between the gable roof sheets and the gutter.
Fix to the end plates of the rafter bracket using two M12 bolts, with
the bolt head on the 150 attachment beam side. Insert spacers to
prevent the beam from crushing, and bolt in position, using nuts
and washers.
The 150 attachment beam becomes the base for the attachment of
the Clearspan Gable unit. (Figure 6) shows a unit attached at the side.
Note: Do not over tighten bolts as this can lead to a visible
indentation due to the high gloss nature of the material. Refer to
(Figure 7) for fixing spacers.
To insert spacers drill 13mm holes through the 150 attachment
beam. Then drill 16mm holes on the outside face only, ie, this time
do not drill all the way through. This will allow the spacer to slide in
from the outside and stop at the other side as shown in (Figure 7).
A cover flashing may be ordered as an additional option and custom
made to cover the exposed brackets and holes through fascia. Rivet
flashings in place, (Figure 8) suggests a simplified flashing.
