Roof Pitch

Roof pitch for solar panels at 28° to be calculated at:

  • Right angle Triangle calculator
  • 1.5m higher centre over side posts offers: 2.8m width to side, pitched at 28°.
  • 1.6m higher … offers: 3m width …
  • 2.1m higher … offers: 4m width …

Caravan Deck

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)
  • 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

Living Fence

A living fence or a green fence uses natural growing vegetation as a fence barrier.

Tree Posts

Using trees as living fence posts saves you time and money when putting up a fence. A disadvantage is you don’t get to pick where the posts should go and you can’t be obsessed with straight lines.

Take a pressure treated board and attach that to the tree, then add your fence hardware to the board that you’ve attached to the tree. What that does is it allows the tree to grow against the board without consuming all that hardware over time.

Infrared Cooling Paint

Infrared Cooling Paint, using home made ingredients, reflects maximum radiant heat, directed upwards back towards the sky and the cold of outer space. Keeping objects behind it cooler than ambient temperature.

Practical applications could include cold storage rooms, or protect heat sensitive devices.
