homes are cleverly built and to some degree of complexity.
They are designed to withstand the weight of snow that
accumulates on the roof during winter. Most houses have
two pillars, with slight differences in their arrangement,
- the haystacks having just a central one.
Our house has a king post called esteo and smaller one
at the top. Between the two are beams which support the
caizo. (upper space) The main post is not in
the centre of the house but somewhat to one side which
makes room for the kitchen. Besides these main pillars
there are two braces, one next to the main post and the
other a little lower.
These braces and posts support most of the weight. Above
these are other beams called aiga or rafter (from
the caizo upwards) and cume which comes down
from the caizo) – from the centre of the
roof other beams known as tercias serve to distribute
the weight on the side of the roof.
Another element of the structure are the cangos,
rafters that rest on the wall and reach to the top of
the roof. At the top they are bound with pinos
(wooden blocks) to the beams mentioned above (aiga
and cume) and they are placed at a distance approximately
one meter apart.
On the cangas are placed the ripias,
which are wooden planks tied with pinos. The
thatch is tied to the cangas and to the ripias.
It is interesting to note that in the timer frame, the
wood used to join planks was always willow. A hole would
be bored in the planks to be joined, using a large manual
drill; a thick plug was passed throught the hole and joined
to the next. Later on iron nails were used but wooden
plugs were still used as the planks were influened by
changes in temperasture and humidity. If the whole building
is made of wood, these changes in temperature take place
all over, evenly, and prevents the wood from splitting..
