1.0 INTRODUCTION

2.0 ATTACHING TO AN EXISTINGSTRUCTURE

2.1 ATTACHING ON SIDE TO HOUSE

2.1.1 RAFTER STRENGTHENING

Please read these assembly instructions thoroughlybefore commencing the construction. Double checkall dimensions, levels and bolting locations beforecutting, screwing or bolting structural members. It isrecommended that the persons erecting the structurehave had some previous building experience becausesome modifications to the existing house structureare required.

The builder is to ensure the existing house/structureis of a suitable structural integrity and complies withall the relevant Australian Building codes andstandards. For more information regarding thesuitability of the house structure to accommodate theStratco Attached Multispan Gable, consult a structuralengineer or a building authority. It is the buildersresponsibility to ensure that the existing house roofstructure is strengthened correctly.

Refer to Section 2.1 if attaching Multispan Gable onit’s side to a house, Section 2.2 if attaching on it’s endto a house or refer to both Sections if attaching thegable on it’s side and end.

A Stratco Multispan attached on it’s side to a house isattached to the existing eaves overhang at the fasciaor to an existing wall if height permits.

The first objective in the construction is to fix astructural side beam along the fascia or wall, to whichthe Gable Unit is attached. Most existing houses havenot been designed for the attachment of portalframed gables to their side, therefore additionalstrengthening of the house rafters must beperformed.

In order to strengthen the existing house rafters, theroof tiles or roof sheets need to be lifted, to exposethe roof frame. Steel rafter brackets and channels arethen bolted along the house rafters. Refer to Section2.1.1.

A 150mm Outba beam is bolted to thestrengthening brackets at the fascia. Once the 150attachment beam is secured to the house, the GableUnit can be erected and fastened to the beam.

The first step is to determine the number of rafterswhich need to be strengthened and their locationrelative to the unit. You will have to lift some roof tilesor roof sheets to discover the rafter positions andspacings. The number of rafters which need to bestrengthened is determined by the builder, however,spacing is recommended not to exceed 1200mm.

ck

Note: It is the builders responsibility to ensure theexisting rafters and fascia are adequately reinforcedand strengthened to accommodate any additionalattached structure. The reinforcing method must beapproved by the appropriate council or engineer.

It is recommended an adjustable rafter strengtheningbracket is used in conjunction with an extensionchannel, as shown in Figure 4.

The adjustable rafter strengthening bracket is shownin Figure 3. Please note that this bracket may not besuitable for applications where the front face of thehouse gutter is higher than 120 mm. In these casesplease contact Stratco for alternative solutions.

ADJUSTABLE RAFTER STRENGTHENINGBRACKET 3

Fixing Rafter Strengthening Brackets andChannels

The adjustable rafter strengthening bracket allows foran adjustment of pitch in the range of 15 to 30degrees. The distance the bracket extends past thefascia is also adjustable to allow for standard gutters(minimum extension) or box gutters with a width ofup to 200mm.

In conjunction with rafter strengthening brackets, achannel is fixed to the side of the house rafter (Figure4). The bottom end of the channel will be located atthe base of the house rafter. Holes should be markedand pre-drilled in the channel to suit the location ofexisting holes in the bracket. The channel will extendbeyond the bracket so additional holes are to bedrilled in the channel at approximately 500mmcentres.

Fixing the 150 Attachment 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 locatedat a height on the bracket which allows clearancebetween the gable roof sheets and the gutter. Fix tothe end plates of the rafter bracket using two M12bolts, with the bolt head on the 150 attachment beamside. Insert spacers to prevent the beam fromcrushing, and bolt in position, using nuts and washers(only use washers to the outside face of the beam).

Do not over tighten bolts as this can lead to avisible indentation due to the high gloss nature of thematerial. Refer to Figure 8 for fixing spacers.

To insert spacers drill 13mm holes through the 150attachment beam. Then drill 16mm holes on theoutside face only, ie, this time do not drill all the waythrough. This will allow the spacer to slide in from theoutside and stop at the other side as shown in Figure8.

Tpiece connection bolts are to be tightened to aminimum 50Nm torque.

Fix the bracket as close to the base of the gutter aspossible (recommended minimum distance 10mmfrom lowest end of gutter), as shown in Figure 6.

The 150 attachment beam is to be fixed to the endplate to ensure the carport roof sheets drain into theexisting house gutter (Figure 6).

Initially the bracket T piece shall be fixed to thebracket arm with two M12 cup head bolts (handtighten only), a spring washer is to be located betweenthe standard M12 washer and nut (Figure 5). Mark theposition of the bracket on the fascia and notch arectangular hole in the fascia allowing the bracket tobe fed through the front of the fascia. The hole mayneed to be enlarged slightly if the M12 cup head boltsinterfere with the fascia.

If fixing a Multispan Gable on its end to a wall, twoalternatives are available. Purlins are fixed directly tothe wall using 68mm wall brackets and valley beamsusing beam to wall brackets. This option will notrequire a rear gable frame and back channel is fixed tothe wall to accommodate sheets running along thewall. The other alternative requires valley beams befixed to the wall and a rear gable frame installed forfixing purlins. The rear gable frame will need to beslightly offset from the wall to allow the appropriatebracket fixing.

If fixing a Multispan Gable on its end with suspensionbrackets to a fascia (Figure 10), typically a soakerflashing is used. In this case the gable rafter at the rearof the unit is to be set back sufficiently from the housefascia to accommodate the house gutter and infillpanel (refer Figures 20 and 21).

If fixing a Multispan Gable on its end to an attachmentbeam, elevated to the existing house gutter height,the attachment beam is to be as close as possible

5.2.2.2 HEADER FLASHING

When a gable is fixed at the rear to an attachmentbeam, elevated to the existing house gutter height,typically a header flashing is used in conjunction withthe rear infill. In this case, the rear attachment beamis considered a header, and along with the rear gableframe is fixed as close as possible (within 5mm) to theexisting gutter in order to accommodate the headerflashing. The gable frame is fixed on the rear headerover end rafter brackets (Figure 19).

Fix the header flashing into position over the existinggutter lip with rivets. Infill panels are located behindthe header flashing and fixed with split tail soft pullrivets at 500mm centres (Figure 22).

SETBACK

5.2.2.1 SOAKER FLASHING

In the case of a rear infill panel, a soaker flashing isused to conceal the existing house gutter, waterproofthe rear end of the gable and neatly finish the base ofthe infill panel (Figure 20).

The rear gable frame and header beam are set back toaccommodate the standard soaker flashing which isoptional with the Outback unit (Figure 21). The frameis fixed on the rear header over end rafter brackets(Figure 19).

Fix the standard soaker flashing into position on topof the back channel and underneath the gutter. Infillpanels must be fixed with split tail soft pull rivets at500mm centres a minimum of 20 mm above the panof the soaker flashing. This will reduce the possibilityof moisture being absorbed into the sheet.


6.0 PURLINS

The top purlin is positioned a maximum of 100mmfrom the gable ridge (Figure 23). The lowest purlinshall be a maximum 50mm from the valley beam(Figure 23) and any intermediate purlins are spacedevenly on rafters, ensuring maximum recommendeddeck end spans are not exceeded. Where there is nopurlin overhang ensure that the end of the purlins areflush with the top of the rafter chamfer, as in Figure39.

Top purlins must to be positioned 100mm fromthe gable ridge when fitting a Ventridge.

Where purlins are continuous over rafters they arefixed in position using 14x95 hex head self drillingscrews. If it is necessary for purlins to be broken overstandard gable frames (ie, purlins continue in thesame direction past a join) a 68mm in-line purlinconnector is used.

By drilling pilot holes and screwing through thetop of the purlin before lifting it into position, theprocess of screwing into the rafters is made easier.Pilot holes should also be drilled through rafters at thefixing location.

To prevent moisture from entering the beams and foraesthetics, any beams with exposed ends requireendcaps be fitted. Align the endcap and push into theexposed beam end.

The postcaps can be fitted over the post-beamconnection. Align the two lugs with the two exposedholes of the post bracket and push firmly.

. Gutters willneed to be mitred if they continue around a corner. Allgutter joins are to be waterproofed with silicon.

Where there is no flat roof adjacent to the gable, thegutter is attached with gutter straps and flatconnecting strips which are fixed to the valley beam.Cut the strip into sections and rivet at 1000 mmintervals to the valley beam. Fix the gutter to the stripwith rivets as shown in Figure 28. Once decking isattached (Section 12.0) the gutter is secured to theroof sheeting using gutter straps at maximum1000mm intervals. Gutter straps may need to be bentslightly so they can be rivetted to the roof sheets.Waterproof rivets with silicone.

If a flat verandah is included connect the gutter to theflat roof Outback as described in ‘Outback FlatAttached Verandah Patios & Carports’

12.0 ATTACH DECKING

12.1 FLAT ROOF (IF APPLICABLE)

Attach the decking to the flat roof verandah first aslaid out under "DECKING" (‘Outback Flat AttachedVerandah, Patios & Carports’), starting from the valleybeam and working away, on both sides.

The back channel is attached upside down (the shorterleg on top) along valley beams to assist the fixing ofdecking. (Figures 30 and 31). The channel extends tothe end of the valley beams. Screw roofing through theback channel into the beam to standard fixingrequirements.

Figure 30 shows the back channel and Outback deckrunning parallel fixed to a 150 valley beam. Figure 31shows the back channel and Outback deck runningperpendicular to a 150 valley beam.

12.2 MULTISPAN GABLE

When attaching the decking to the gable, start fromthe front, aligning the sheets so as to avoid the purlinfixing screws.

If the deck of the flat roof section runs perpendicularto the valley beams, align the ribs of the gable deckingup with the flat roof section. Fix the decking so that itis level with the top of the flat deck, and so there is amaximum 100 mm gap at the ridge (Figure 32).

When using polycarbonate or corrugated roofing noback channel is required at the ridge. When Outbackdeck is used, back channel is required at the ridge,and is supplied with the unit (Figure 33).

For polycarbonate roofing, screws include special‘polycarbonate’ washers and 10mm holes are to bepre-drilled in the sheeting prior to fixing to allow forthermal expansion.

13.2 OUTBACK VENTRIDGE

Fit the vent ridge stop ends over either end of the ventridge base using their tabs to locate and hold them inplace. Secure the bottom tab of the stop ends to thebase from above with a 4-3 rivet either side.

Lift the base onto the apex of your gable unit. Securethrough the base and roofing sheets into the purlinbelow at maximum 900mm centres either side usingstandard CGI or polycarbonate roofing screws asrequired (Figure 35). For polycarbonate roofing, pre-drill 10mm diameter holes through the base and roofsheet prior to fixing.

Place the vent ridge cap on top of this assemblymaking sure to keep the ends flush with the outsidesurfaces of the stop ends.

Starting at one end, evenly space four 4-3 rivets (twoeither side of the apex) 5mm in from the edge. Ensurethat the top two rivet nearest the apex on either sidegoes through all three components to fasten the capto the stop end and the base; the outer rivet willfasten the cap to the stop end.

Repeat this on the other end and then secure the capto the base at maximum 900mm centres using a 4-3rivet 40mm out from the apex on both sides.

Waterproof all rivets with silicone.

14.0 INFILL PANELS

Two styles of header flashings are available to neatlyfinish the base of infill panels, one is used on headerbeams with gutter and the other for headers withoutgutter. Gable infill panels are to be cut in triangularshapes to fit the end frame. Panels can be painted tothe desired colour before installing.

End struts are fixed mid-span of the header to aheader beam bracket at the base and an end strutplate at the ridge (Figure 36).

15.0 ATTACHING BARGE CAPPING

If barge capping is required at the ends of the unit,attach the barge cap by screwing the lower lip to therafter and screw the top section to the purlin throughthe deck, as shown in Figure 39. Mitre the barge at theapex of the gable for a neat finish. Run the barge capalong the gable section to where it meets the flatverandah deck and finish neatly.

For polycarbonate roofing, pre-drill 10mmholes in the sheeting before fixing the barge.

If infill panels have been installed, the lower lip of thebarge capping should cover the panel screws to give aneat finish.

17.0 HELPFUL TIPS

18.0 MAINTENANCE

Thoroughly check posts with a spirit level. Whenplumb, fill the post hole with approximately 150mmof concrete and use a shovel or pole to agitate theconcrete to remove and air pockets. Repeat thisprocess until the hole is full, continually checking theposts. Once the concrete is set remove any temporarybracing or props. The concrete must be finishedslightly raised towards the column to ensure waterruns away from the column.

If fixing the columns to an existing concrete slab witha footing plate, each plate must be fixed to theconcrete as specified in Figures 26 or 27 asappropriate. The minimum distances from an anchorhole to the concrete edge is 75mm.

Before attaching the downpipes, rivet the downpipebracket to the column and bend the flanges along the‘break-line’ to accept the downpipe. Slide thedownpipe over the downpipe outlet and rivet intoposition. Rivet the downpipe to the brackets.Weatherproof all fasteners with silicone.

Leave plastic coating on members until they are aboutto be fastened to the structure. This will help preventscratching of the colorbond finish.

Sweep the roof and clean gutters after the completionof work. Ensure any swarf and rivet stubs are removedas they can cause unsightly rust stains.

Double check all measurements and drilling locationsbefore proceeding.

Regularly check framework for squareness andvertical alignment to make sure it hasn't movedduring construction.

Leave all construction props and/or bracing in placeuntil concrete is set or columns are bolted to the slab.
