Valley and hip framing detial

Lean to seperate to existing dwelling.

No joist hangers, multi grips therefore all joins had to be very accurate. iron sand colour steel and clear-light roofing was used.

Barge flashings and apex flashing installation.

Exterior Envelope / Frames and Structures

Re-framing and straightening exterior, gable-end wall. Preparing to be wrapped in flexible wall underlay (wrap) and clad with fibre-cement weatherboard. Structure is an existing lock wood style build, with battens that cladding is directly fixed too. 

New cladding is required to be fixed off at 600mm centres. Existing battens varied in spacings and straightness therefore were removed.

I plumbed and straightened each end ‘stud’ then used string-lines to straighten top and bottom battens. Once window openings were framed up I installed and straightened stud battens at 600mm centres and framed around window openings. I then installed top jack battens and made sure they were straight and plumb. 

Health and Safety - Extra caution as working from heights, be aware of people and falling debris.

Materials - h1.2 90x45mm pine, 90mm galv nails, damp proof course (packing)

Frames and Structures / Interior Lining and Finishing

Building an in-situ wing-wall running up to a raking ceiling. Wall was built in relation to kitchen plan to allow for cabinets, etc. to be built around it. Wall also frames around the tight staircase and had a 39° slope to prevent anyone from hitting their head when using stairs. Frame was made using h1.2 treated 90x45mm pine timber with 90mm galv hot dip nails. Once posioton of frame had been worked out and marked in accordance with kitchen plan we used a laser level to plumb a mark up on the ceiling to position our top plate correctly.

Before ceiling was framed we installed extra nogs between ceiling battens for fixing for our top plate. Frame was then lined with untreated 90mm groove ply. Skirting, scotia and beads were then fixed in to position.

Roof framing - installing h1.2 70x45mm purlins with strap bracing as required according to roof frame plan.

Frames and Structures 

A lot of straightening and adding extra fixing for sheet joins etc. Clients decided on 150mm grooved ply running horizontally along walls with 90mm trim (architraves, scotia, skirting and join batterns). Central internal wall we kept as exisiting only to find out it had a 14mm bow in the middle therefor we had to pack each side out to suit. In hindsight a complete rebuild of wall would have been for sufficient. To straighten I used a laser level to check each 4 corners of wall and pack/plane to suit. Once corners are the same I set up string lines to work my way along the top and bottom plates until they were all straight and plumb. Each stud was then packed and nogs accordingly.

Frames and Structures

Building stringer to attach to exterior house with 15mm packers to allow for any water run off. We also used EPDM washers when coach screwing stringer to wall to seal any potential water leeks. Glulam beam bearers were etched into the side of our piles and then coach bolted on as per required in the plan. 190mmx45mm h3.2  joists were used at 450mm centres to prevent any bounce in floor. 140mm Purple heart decking boards will be used. We used the dumpy laser level to find the height at which to cut the piles so that top of decking floor boards will be flush with rebated slider door.

Frames and structures / Exterior envelope

Installing rafters for rasied pitch roof plane. Pitch was been raised from 15° to 3°. Rafters are all 240mmx45mm h1.2 pine. We used 90x45mm purlins to allow for a longer cantilever span. Strap bracing was installed We laid self supporting roofing underlay horizontally, ensuring laps where at least 150mm and we worked form the bottom up.
