For the development of the constructive system,
three basic materials were used: wood, guadua and a mortar
for lining.
Wood
Wood was used as the panels’ structural
material formed by studs, and headers (top and bottom), creating
this way, a structure able to support the vertical and horizontal
forces affecting the houses.
Characteristics
- Common Name: Chontilla
- Color: Light brown with dark longitudinal
veins.
- Qualification: Type TO (hard)
- Immunization: Nebubon + Kerex
Guadua Cane
Chopped cane was used to cover the wooden structural
panels, fixing it to the wood by means of nails and galvanized
wires.
Guadua is fit for use once it reaches maturity
that is between 3 and 5 years.
It is necessary that before it is used, the
soft part or "gut” must be removed from the interior
face of the cane, preventing this way the attack of moths,
fungus and mildew.
Characteristics
- Common Name: Guadua Cane, (chopped cane,
cane sheat)
- Color: Yellowish Green with white stains
(3-5 years)
- Size: Variables
- Immunization: Pentachlorophenol at 5% +
kerex (immersion). traditional norms should be complied
with (age, waning, tide, cleaning of the soft part)
Mortar
The mortar was applied, as coating, to interior
and exterior house walls, isolating wood and guadua from the
environment, protecting it from fire and providing sturdiness,
as well as an acceptable quality and durability finish.
Mixture Proportion.
1: 2 1/2 (cement and sand) applied in two layers.
Other materials
Iron
Iron was used, in the constructive system,
in the following ways:
- Wire rod ties in subflooring; 30-centimeter
Ø 6 mm bars, were used to strap the bottom header
of the panel.
- Foundation Reinforcement; 30-centimeter
Ø 8 mm bars were placed in the corners of the foundation.
Panel connection
The panels were connected by means of Ø
6 mm bars nailed to the studs of the connecting panels.
- Wire Rods in reinforced concrete pillars
for vertical strapping of panels (joining of two constructive
systems)
- Support in the conventional constructive
system reinforced concrete structures.
