Prototype For Adjustable Height Footing Base Plate & Leg for Small & Light OutBuilding / Shelter Mk 1 & Mk 2. (untested)

MK 1


To design a footing  base plate with adjustable height. This is to cope with uneven ground or a flood risk area


Using a scaffolding 4 tonne  Base Jack (cost £6.5) , turned upside down & inserted into a tube clamp hand rail holder. Then carrying on into a hole, so end is inserted into soft ground.

The base plate is made of 2 layers of cross facing composite door offcuts (top & bottom)  nailed gunned with 75mm nails & glued with Everlast Lumberjack Pu glue (5 min cure)

 A longer section of rebar is inserted as well. to a deeper depth.

Seperate 10-12mm rebar rods may be inserted at an angle if required. Alternatively a concrete fence post beam can be placed on top of the base plate. The concrete beam could be used as thermal mass, perhaps with a heat harvesting fluid pipe system from the roof.

 The base or frame of shelter can be screwed. or preferably bolted to base jack via 4 holes

Mk. 2 

30cm long 48.3mm Dia. aluminium  scaffolding pole with m24mm nuts inserted with hammer / hydraulic press at bothe end. 

3 x  scaffolding base plates have their centre removed with a hammer, and the bolts are threaded though nuts ateither end

Shows nut hammered into tube. Although a tight fit, edges have been bashed over to  stop nut from coming out (testing will determine if thsi is necessary )

  1. You're a best!! Very well done and explained because i'm trying to set up a aluminium scaffold and it seems a bit difficult... Thanks for the tips Cabinz

Plan to make a low cost hardware kit to allow low income groups to build locally sourced (preferably reused) panels to make foldable shelters like Hexayurts, or for childrens play dens, animals pens or room dividers to reduce heating costs and noise
