Prepare all posts wood timber treatment against damp rot, fungus and termites.
- 6m x 3m deck with cover.
- 3m x 3m deck sections:
- 4 beam frame.
- Joists, w/2 hangers each.
- 6 EVEN joists every 430mm apart.
- [ | I | | I | ] but horizontally! OR
- 7 ODD joists 375mm apart. Never more than 450mm apart.
- [ | | | I | | | ] but horizontally!
- held by min; 12 EVEN or 9 ODD Support Posts in-ground. OR 1 post per joist through the middle.
- Joist Bridges to spread load to nearest Support Posts, through middle.
Roof
- Thick Posts may be spaced long upto 6m apart. Depth is impacted by roof pitch and need for solar panel mounting if required.
- Allow +10cm buffer on measurements to trim down after setting in.
- Calcs for roof pitch for solar panels, if needed/viable.
- 4.8m (level ground) Centre posts sunk 1m; w/ 3.8m above ground. 1.6m higher than side posts for a 3m span.
- Solar panel pitched roof and this post Heights may be unfeasible, due to southern coastal wind risks. Requiring posts and roof truss to sit just 50cm above caravan and separate steel frame on roof for panel angling.
- 3.2m (+gradient delta: ~4m?) Front posts sunk 90cm; w/ 2.2m above ‘level’ ground deck. (Ideally >2.4m above level ground deck)
- 4.8m (level ground) Centre posts sunk 1m; w/ 3.8m above ground. 1.6m higher than side posts for a 3m span.
- Affix with:
- 30cm Rebar with auger to pin together posts.
- Metal strapping to secure joints and cross bracing.
- Fence wire bracing supports.
- Roof bracing every xm
