A small wood hut

A small wood hut

Something I'd been planning to do for a while. Not a big project, just needed to sit down and work out the basic dimensions and materials then throw it together. The main features are a reciprocal roof consisting of 6 beams supported on 6 poles for the walls. Some metal sheeting on the rainy, windward side and chip limestone on the floor. Rubber roof membrane with ferocement to top it all off.May 08, 2019

Reciprocal roof (self supporting)

Reciprocal roof (self supporting)

The reciprocal frame is a roof structure where each beam both supports and is supported by other beams in the roof structure. A minimum of 3 beams is required to create a reciprocal frame roof. As each beam supports the next in a reciprocal manner no internal support structure is required.  Only the outer end of each beam requires support which will normally be a post used for the wall.  The roof loads are transferred to these posts and in turn to the supporting foundation. The beams can be fabricated from timbers, laminated wood, steel or reinforced concrete. A very inexpensive roof structure can be made from logs.

While building it you need to support the first beam temporarily; when the support is removed the whole structure should neatly lock together.
