1.0 INTRODUCTION
2.0 ATTACHING TO AN EXISTINGSTRUCTURE
2.1ATTACHING ON SIDE TO HOUSE
Please read these assembly instructions thoroughly beforecommencing the construction. Double check alldimensions, levels and bolting locations before cutting,screwing or bolting structural members. It is recommendedthat the persons erecting the structure have had someprevious building experience because some modificationsto the existing house structure are required.
The builder or council is to ensure the existinghouse/structure is of a suitable structural integrity andcomplies with all the relevant Australian Building codes andstandards. For more information regarding the suitability ofthe house structure to accommodate the Stratco AttachedMultispan Gable, consult a structural engineer or a buildingauthority. It is the builders responsibility to ensure that theexisting house roof structure is strengthened correctly.
Refer to section 2.1 if attaching Multispan Gable on it’s sideto a house, section 2.2 if attaching on it’s end to a house orrefer to both sections if attaching the gable on it’s side andend.
A Stratco Multispan attached on it’s side to a house isattached to the existing eaves overhang at the fascia.
The first objective in the construction is to fix a structuralside beam along the fascia or wall, to which the Gable Unitis attached.
Most existing houses have not been designed for theattachment of portal framed gables to their side, thereforeadditional strengthening of the house rafters must beperformed.
In order to strengthen the existing house rafters, the rooftiles or roof sheets need to be lifted to expose the roofframe. Steel rafter brackets and channels are then boltedalong the house rafters. Refer to section 2.1.1.
A 150 mm Outba beam is bolted to the strengtheningbrackets at the fascia. Once the 150 attachment beam issecured to the house, the Gable Unit can be erected andfastened to the beam.
The first step is to determine the number of rafters whichneed to be strengthened and their location relative to theunit. You will have to lift some roof tiles or roof sheets todiscover the rafter positions and spacings. The number ofrafters which need to be strengthened is determined by thebuilder.
: It is the builders responsibility to ensure the existingrafters and fascia are adequately reinforced andstrengthened to accommodate any additional attachedstructure. The reinforcing method must be approved by theappropriate council or engineer.
Use an adjustable rafter strengthening bracket and onechannel for eaves overhangs up to 450 mm. Use anadjustable rafter strengthening bracket and two channelsfor eaves overhangs over 450 mm and up to and including600 mm, as shown in figure 4.
The adjustable rafter strengthening bracket is shown infigure 3. Please note that this bracket may not be suitablefor applications where the front face of the house gutter ishigher than 120 mm. In these cases please contact Stratcofor alternative solutions.

Fixing the 150Attachment Beam in Place
After fixing all the brackets and channels, the 150attachment beam is fixed in place.
Prop up the 150 attachment beam in position with thedouble flange on top, the beam will need to be located at aheight on the bracket which allows clearance between thegable roof sheets and the gutter. Fix to the end plates of therafter bracket using two M12 bolts, with the bolt head on the150 attachment beam side. Insert spacers to prevent thebeam from crushing, and bolt in position, using nuts andwashers.
Do not over tighten bolts as this can lead to a visibleindentation due to the high gloss nature of the material.Refer to Figure 8 for fixing spacers.
Note:

Fixing Rafter Strengthening Brackets andChannels
The adjustable rafter strengthening bracket allows for anadjustment of pitch in the range of 15 to 30 degrees. Thedistance the bracket extends past the fascia is alsoadjustable to allow for standard gutters or box gutters with awidth of up to 200mm.
In conjunction with rafter strengthening brackets, channelsare fixed to the side of the house rafter (Figure 4). Thebottom end of the channel will be located at the base of thehouse rafter. Holes should be marked and pre-drilled in thechannels to suit the location of existing holes in the bracket.The channel will extend beyond the bracket so additionalholes are to be drilled in the channel at approximately500mm centres.
Initially the bracket T piece shall be fixed to the bracket armwith two M12 cup head bolts (hand tighten only), a springwasher is to be located between the standard M12 washerand nut (Figure 5). Mark the position of the bracket on thefascia and notch a rectangular hole in the fascia allowingthe bracket to be fed through the front of the fascia. The holemay need to be enlarged slightly if the M12 cup head boltsinterfere with the fascia.

Insert the bracket through the fascia and fix with thechannel(s) to the house rafter using M12 hex head boltsthrough the existing holes in the bracket and further up thechannel(s) (Figure 7). Adjust the T piece so it is horizontaland has the appropriate extension past the fascia to allowfor fixing of the attachment beam. T piece connection boltsare to be tightened to a minimum 35Nm torque.
Fix the bracket as close to the base of the gutter as possible(recommended distance 10mm from lowest end of gutter),as shown in figure 6.
The 150 attachment beam is to be fixed to the end plate toensure the carport roof sheets drain into the existing housegutter (Figure 6).
The 150 attachment beam becomes the base for the attachment of the Multispan gable unit. Figure 7 shows a unit attached atthe side.

You would have ordered and received your custom madeflashings to cover the exposed brackets and holes throughfascia. Rivet flashings in place, figure 9 suggests asimplified flashing. You may however use your imaginationand design a flashing that suits your individual taste.
Note: It is the builders responsibility to ensure the existingrafters and fascia are adequately reinforced andstrengthened to accommodate any additional attachedstructure. The reinforcing method must be approved by theappropriate council or engineer.
If fixing a Multispan Gable on its end to a wall, twoalternatives are available. Purlins are fixed directly to thewall using 68mm wall brackets and valley beams using 150beam to wall brackets. This option will not require a reargable frame and back channel is fixed to the wall toaccommodate sheets running along the wall. The otheralternative requires valley beams be fixed to the wall and arear gable frame installed for fixing purlins. The rear gableframe will need to be slightly offset from the wall to allow theappropriate bracket fixing.
If fixing a Multispan Gable on its end with suspensionbrackets to a fascia (Figure 10), typically a soaker flashingis used. In this case the gable rafter at the rear of the unit

6.2. REAR INFILL
A rear header beam will be required if the unit includes infillto the rear gable frame. For units attached at the rear withsuspension brackets, the rear header is fixed betweenvalley beams using beam to beam brackets. If fixed at therear to an attachment beam (Figure 26), the attachmentbeam becomes the header (valley beams are fixed to theheader beam) and if attached on the side the rear header isfixed to the attachment beam with beam to beam brackets.
Attach end rafter brackets to the rear header beam atspacing, O, as determined in section 3 using six 10x16hex head self drilling screws (Figure 23).
Fasten the rafters that form the end gable frame over theend rafter brackets with a minimum of two 10x16 hexhead screws either side (Figure 23).
Refer section 14 for details of fixing infill panels to gableframes.
6.2.1 SOAKER FLASHING
In the case of a rear infill panel, a soaker flashing is used toconceal the existing house gutter, waterproof the rear endof the gable and neatly finish the base of the infill panel(Figure 24).
The rear gable frame and header beam are positioned 153mm from the house fascia in order to accommodate thestandard soaker flashing which is optional with theOutback unit (Figure 25). The frame is fixed on the rearheader over end rafter brackets (Figure 23).
Fix the standard soaker flashing into position on top of theback channel and underneath the gutter. Infill panels mustbe fixed with split tail soft pull rivets at 500mm centres aminimum of 20 mm above the pan of the soaker flashing.This will reduce the possibility of moisture being absorbedinto the sheet.
Refer section 14 for details of fixing infill panels to gableframes.

2. Do not form stop ends at either end of the soaker flashing.
3. Soaker flashing is not to come in contact with the base ofthe house gutter.
6.2.2 HEADER FLASHING
When a gable is fixed at the rear to an attachment beam,elevated to the existing house gutter height, typically aheader flashing is used in conjunction with the rear infill. Inthis case, the rear attachment beam is considered aheader, and along with the rear gable frame is fixed as closeas possible (within 5mm) to the existing gutter in order toaccommodate the header flashing. The gable frame is fixedon the rear header over end rafter brackets (Figure 23).
Fix the header flashing into position over the existing gutterlip with rivets. Infill panels are located behind the headerflashing and fixed with split tail soft pull rivets at 500mmcentres (Figure 26).
Refer section 14 for details of fixing infill panels to gableframes.

Having all the Perimeter Brackets in place will allow raftersto be located. The two shorter rafters are to be positionedclosest to the end gable frame on either side. It is importantthat rafters are firstly fixed at the apex, position rafters overthe apex bracket tabs so the cut face of the rafter is flushwith the face of the bracket.
Two 12x20 hex head screws are used to fix the rafter to thetab with the first screw being located 20mm from the frontface of the bracket and the second 20mm from the firstscrew (Figure 28). This process is repeated for the twointernal gazebo hip rafters.

With all gazebo rafters fixed at the apex they can befastened to the perimeter brackets. Fix rafters through thebase of the perimeter brackets using two 12x20 hex headscrews at a minimum spacing of 30mm. As a smalltolerance is allowed for at this bracket it is important that thescrews are located at least 20mm from the bracket edgeand the bottom edge of the rafter (Figure 29).
9.0 PURLINS
9.1 CUTTING PURLINS
The location of all the purlins must be known before anypurlins are to be cut. The top purlin is positioned a maximumof 100mm from the gable ridge (Figure 30) and ends at thefront edge of the gable frame on either side. The end of thispurlin is cut straight to be left flush with the top of the rafterchamfer (Figure 31).
The lowest purlin shall be a maximum 50mm from the valleybeam (Figure 30) and any intermediate purlins are spacedevenly on rafters, ensuring maximum recommended deckend spans are not exceeded. Both the lowest purlin andintermediate purlin/s will follow the shape of the gazebo endand therefore purlins will need to be mitred at 67.5 to lengthto suit this shape. The highest edge of the gazebo endpurlins will end at the centre of the top face of gazebo hiprafters. Refer to Figure 31 for further details.
It is recommended the three lowest purlins aroundthe front of the gable end are set as low as possible on thehip rafters to eliminate any gap between purlins and gazebofascia beams. It is not critical that the level of the lowestpurlins exactly match the purlins adjacent to the valleybeams.

9.2 ATTACHING PURLINS
Where purlins are continuous over rafters they are fixed inposition using 14x95 hex head self drilling screws. If it isnecessary for purlins to be broken over standard gableframes (ie, purlins continue in the same direction past a join)a 68mm in-line purlin connector is used.
By drilling pilot holes and screwing through the top ofthe purlin before lifting it into position, the process ofscrewing into the rafters is made easier. Pilot holes shouldalso be drilled through rafters at the fixing location.
In the case of purlin joins which occur over a gazebo hiprafter an angled purlin connector will be required. Fix purlinstogether using 12x20 hex head screws. A 14x95 hex headself drilling screw is fastened through the connector to holdpurlins to the rafter (Figure 32). A gap will be noticed at thelower edge of the purlin join but this will not be seen afterinstallation of the purlin intersection cover.
If purlins do not align (ie, lowest gazebo end purlins andlowest gable purlins) they may be screwed directly into hiprafters.

Note: Purlin Intersection Caps are available as an optionalextra and can be used to fill the small gap between the purlinand the template cut out. Caps are riveted to the side of thepurlin cover.
With the exception of Gazebo Ends with Outback®
deck, hipsupport flashings ( Figure 2) are secured directly over purlinintersection covers to hide roof sheeting cuts. Fix theflashing to purlins at each purlin junction using a single riveteither side of the flashing.
Mitre hip support flashings at the apex for a neat finish.
Connect the gutter to the flat roof Outbacks as described in
Assemble the remaining framework of the verandah as perthe installation guide ‘Outback Flat Attached Verandahs,Patios & Carports’.
Fix the posts, as described in the instruction brochure under"COLUMNS AND FOOTINGS” or "ALTERNATIVEFOOTING".
Note: All adjustable construction props are to be left inposition until decking is attached and concrete is set.
‘Outback Flat Attached Verandahs, Patios & Carports’.Gutters will need to be mitred at the point the flat roof unitmeets the gable and around the front of the gazebo end. Allgutter joins are to be waterproofed with silicon.
Where there is no flat roof adjacent to the gable, the gutter isattached with gutter straps and flat connecting strips whichare fixed to the valley beam. Cut the strip into sections andrivet at 1000 mm intervals to the valley beam. Fix the gutterto the strip with rivets as shown in figure 34. Once decking isattached (Section 12.0) the gutter is secured to the roofsheeting using gutter straps at maximum 1200mmintervals. Gutter straps may need to be bent slightly so theycan be rivetted to the roof sheets. Waterproof rivets withsilicone.
The above method is also used to fix gutter around the frontof the gazebo perimeter beams.

9.3 PURLIN INTERSECTION COVER
The purlin intersection covers are used to cover any gaps atpurlin joins and also to attach decking. The location ofpurlins are to be marked along each side of the purlinintersection cover and the cover is then cut with tin snips toallow a tight fit over purlins. The template provided will allowthe cut shape to be marked on the cover at the location ofeach purlin.
The purlin intersection cover is now riveted on either side tothe chamfer of the rafter, rivets are to be located a maximumof 50mm from purlins on both the higher and lower sidesand at spacings of no more than 300mm (Figure 33)
Each cover should be mitred at the apex to finish flush withthe gazebo apex flashing.

12.2 MULTISPAN GABLE
When attaching the decking to the gable, start from the rear(non gazebo end) on one side of the gable, aligning thesheets so as to avoid the purlin fixing screws.
If the deck of the flat roof section runs perpendicular to thevalley beams, align the ribs of the gable decking up with theflat roof section. Fix the decking so that it is level with the topof the flat deck, and so there is a maximum 100 mm gap atthe ridge (Figure 37).

12.3 GAZEBO END
At the point when less than one full sheet is required to passthe centreline of the front gable frame on one side, theGazebo End decking will need to be cut to suit. Refer tofigure 39 for cutting order and laying direction.
Continue laying deck past the end gable frame (Section 1,Figure 39) and cut the sheeting along the centreline of thepurlin intersection cover. The offcuts from this section areused in section 2 but deck is layed in the opposite directionas shown by the arrow in figure 39. When all offcuts areutilised begin with new sheeting.
This process is continued around the front of the GazeboEnd and back down the side of the Multispan Gable (i.e.Offcuts from section 2 are used in section 3 with deck beinglayed in the direction shown in figure 39, offcuts fromsection 3 are used in section 4 and so on).
The centreline of the purlin intersection covers areused to mark the sheets for cutting. Sheets are to be takendown from the framework to be cut. It is recommendedsheeting is supported in a horizontal plane off the ground ata comfortable height for cutting.
All sheeting which ends at the apex is to be cut to a point soit meets directly above the centre of the end gable frame.
Gazebo end decking will need to overhang the last purlinand gazebo fascia beams allowing water to flow directlyinto the gutter (Figure 34). It may be necessary to notch thetop of the backchannel on the valley beams to avoidinterference with roof sheets at the first gazebo corner.
The edge of roof sheeting, running along hips, is to be fixedthrough the hip support flashing and into the purlinintersection cover.
Note:
12.0 ATTACH DECKING
12.1 FLAT ROOF
Attach the decking to the flat roof verandah first as laid outunder "THE DECKING" (‘Outback Flat AttachedVerandahs, Patios & Carports’), starting from the valleybeam and working away, on both sides.
The back channel is attached upside down (the shorter legon top) along valley beams to assist the fixing of decking.(Figures 35 and 36). The channel extends to the end of thevalley beams.
Figure 35 shows the back channel and Outback deckrunning parallel fixed to a 150 valley beam. Figure 36shows the back channel and Outback deck runningperpendicular to a 150 valley beam.

16.0 HELPFUL TIPS
Leave plastic coating on members until they are about tobe fastened to the structure. This will help preventscratching of the coloured finish.
Sweep the roof and clean gutters after the completion ofwork. Ensure any swarf and rivet stubs are removed asthey can cause unsightly rust stains.
Do not allow soil to remain in permanent contact with thecolumns, as corrosion will result in the base of thecolumn. Refer to the “Selection, Use and Maintenance ofStratco Steel Products” brochure for complete details ofthe maintenance requirements.
Double check all measurements and drilling locationsbefore proceeding.
Regularly check framework for squareness and verticalalignment to make sure it hasn't moved duringconstruction.
