Pithouse concept, four pole "tripod?"

I wonder if most people would be confused by the proper term for a four pole support structure called a quadripod  (sp?)?   Interesting and workable alternative to the tripod so commonly used on tipis.

I like to think of a "tripod" as having 3 legs but joined at the apex.

All the 4-post houses that I've seen or been in use the posts as the 4 corners of the world.
They hold up the roof beam structure.

You could join all 4 posts at an apex but I can't see how that holds up a roof

Hello RV

Earlier in this thread you will find two resources, one is the four pole tie system (illustrated) used by some Plains Indians and a Reindeer people who used a three forked pole system(see video) ...the Hidatsa people used a similar forked pole system but added fourth pole to create what they thought was a tighter lock of the poles(per Buffalo Bird Woman).

Both systems supported skin lodges, grass and turf roofing.

Hello Folks

Here is an article about the Crow Tipi which has a four pole base system fully explained and the tie of the poles illustrated.

If one wished a four pole base you could probably not due better than the women of the Crow People.

You will see, from both old and contemporary examples in the Pacific Northwest, 
that the four corner posts support a frame which support the roof logs.

In the interior, the roofing material is the spoil from excavating the pit.
On the coast, the house boards are split from the multipurpose western red cedar.  
The biggest house that Franz Boas measured was a Haida dwelling, 40' wide and 100' long.
The biggest single house board was a split of western red cedar, 14' tall x 36" wide x 3/4" thick ( no mean accomplishment.)
Haida stripped their houses and carried those house boards by boat as they moved around seasonal camp villages.
Regional differences in design and construction.

i read an article that said the usual Pit River pit house had 3 support posts. With that quadripod model I made pictured ahove, could it have four support post to hold up those rafters?

I'm thinking about making a pithouse too, I found a spot that I think has deep enough soil. There are a lot of ponderosa pine poles growin there though so I will have to rip out some 4" diameter stumps. And hopefully the water table is low enough. It's a high spot in a riparian area

Dead incense cedar trees have nice poles and the bark is easy to pull off. Juniper would also work but I'm not as farmilar with juniper. I would use fresh trees(or recently killed trees) for the support posts and the cross pieces and I would use dead trees for the roof. I can collect only green juniper, harvesting green cedar, pine, or white fir is not allowed in the nat'l forest.

How thick should the roof poles be for a maybe 10' diameter pithouse?
