Slotted Fence Posts for Shelter Ground Resting Foundations & Strength Test. Slotted Crank Bent Arm Post Idea For Hexayurt

Slotted Fence Posts for Shelter Ground Resting Foundations & Strength Test. Slotted Crank Bent Arm Post Idea For Hexayurt



Pics of other types of concrete fence  posts, apart from slotted ones already experimented with.

When used for foundation beams, vertical frame beams can be slotted in or rebar to fix to the soil, can be threaded through small holes. Also, these holes can be used to join slotted crank arms posts (post with bent top on the right in pic) together to form a hexayurt type shelter base (see rough drawing below)


 slotted crank arms posts (post with bent top on the right in pic 1) may be able to be joined together to form a base together to form a hexayurt type shelter base, The angle looks  the same , but a web sch or mnftr email has not confirmed.

Rebar loops could be used to secure further to the ground

Strength Test for slotted fence post of 150 kg added weight , 9m suspended from edge of both ends. small cracks appears but no failure. (see pic)

Idea was to establish whether galv. purlin was needed underneath to support. I think this is best as if beam cracks,  galn metal skin will contain it & it still function in compression

 PROBLEM. (Pic 1 & 2 ) Due to thickness of roof sandwich panels, flashing is too short. SOLUTION . If longer flashing is not available, add a second row of flashing to extend ( Pic 3) .

Experiment using steel Rebar to attach your shelter to a heavy foundation made from a concrete fence post







Hexayurt & Shelter Footings Design using 3 way treble slot concrete fence posts with Extenson for Decking

Hexayurt & Shelter Footings Design using 3 way treble slot concrete fence posts with Extension for Decking.

Note: this design is not tested in the field yet, whether a buidings weight will crack the fence post is yet to be tested. If it does crack, a galvanised metal purlin can be inserted underneath fence post to spread weight. It is assumed foundation will be on soil / sand or similar


The ain is to avoid digging labour intensive footings, and have a movable low impact system, compatible with the hexayurt. It is heavy to avoid structure tipping over.

Experiments with rebar sunk over fence post into ground for extra stabilisation, are in last pics



The drawing show 4 ft 6" fence posts used, but I would use 9 ft ones as 9ft posts are not much more expensive than 4ft 6" ones.

Overlap can be covered with decking,. 4 ft bottom edge of 6 x 8' x 4' sheets used as walls in hexayurt design)

.  The drawing is for having an extra inside frame if required (black sq in hexayurt drawing) . upright can be attached to edge of post underneath fence post or perhaps rebarred.

If the 3 way fence post is placed with  its flat end on floor, this has 2 side slots & 1 on top to attach a resting floor & upright wall.
