Description of the Domo system
The system allows
for the construction of reinforced concrete shell structures
using a pressurised PVC airform
to act as outer
formwork.
The dome, a
structure used from the antiquity, acquires with Domo a
modern, economic and respectful application with the
environment.
The structures Domo are structures of armed
concrete, which allow the execution of a rapid and simple
way of structures of simple or double curvature, specially
adapted for the resolution of big lights and powerful
horizontal charges, which joined your staunchness makes them
ideal for the construction of big stores for bulks specially.
The constructive process is evolutionary and a self
balance, using as auxiliary element a sheet pressurized
of pvc, pre-stressed and of high resistance that remains
incorporated into the construction as ended in your exterior
face.
For the geometries that can be
obtained and for your out finished they present a very
aesthetic aspect.
Your existence covers needs of
storage, especially of changeable products for changes of
temperature like they can be the cereals, the sugar, the
water, the cement, the coal and other prime matters. This
faculty almost microclimatic turns also to the structures
Domo in perfect candidates for the projection of wines
cellars, since your inscrutability supports also the
conditions of dampness needed. Your utilization in North
America has been extended, besides, to architectural as
sports centres, stadiums, religious buildings, audiences,
complexes of leisure and enclosed housing.
The resistance of these
constructions to the atmospheric phenomena is also notable:
nobody has forgotten that the stadium Superdome of
New Orleans turned into the principal refuge of harmed of
the Katrina hurricane.
PROPERTIES
The structures Domo they are
sheets of concrete shaped by surfaces of simple or double
curvature, which grants to the vault an excellent behavior
opposite to punctual and distributed charges. This improves
the response before the seismic, atmospheric phenomena and
other natural contingencies.
The possibility of incorporating polyurethane foam in the
process of construction optimizes the thermal isolation of
the interior. There diminishes the possibility of phenomena
of condensation, an aspect that makes possible the storage
of cement, sugar, cereals...
Besides, the exterior airform
is impermeable, which reinforces the waterproof capacity of
the polyurethane (for not speaking about the thick cap of
concrete that supposes the own vault). In the constructive
process the concrete projects in successive caps of between
3 and 4 cm, which diminishes the retractions and improves
the impermeability.
They eliminate the concepts of
shaft and cover of the conventional siloes in favour of the
only monolithic structure of armed concrete. This guarantees
a perfect airtight and eliminates the complicated
auctions and maintenance costs that present the conventional
structures generally crowned with metallic structures.
The monolithic union of shaft
and covered it does that the structure presents a better
structural behavior.
The possibility of increasing,
practically without limit, the diameter of support of the
structure, allows to reduce the value of load for square
meter on grouds of few resistance, the height to be
diminished, etc. This characteristic turns to Domo in an
alternative to considering in zones with limitation of
height.
Excellent capacity of adequacy to the differential seats.
The aesthetics improve the environmental impact of the
industrial sets to which they join.
Your form improves the utilization of the interior volume
and your total filling is possible.
The structure of double curvature allows the installation of
automatic systems of extraction produced from the exterior.
The construction allows that there should be extracted 100 %
of the stored material and a capacity of wealth of up to 500
Tn/h (according to the density of the material).
The system allows to adopt solutions with very diverse
geometries that solve a wide variety of problems. The
versatility, together with the possibility of loading on the
whole surface of the structure, allows an ideal utilization
of the surface in available plant and to reduce the volume
of the construction with a maximum adjustment to the
capacity of storage needed.
AN ECONOMIC BET
Minor investment for
better utilization of the occupied surface.
Minor investment for
optimization of the interior useful volume (minor cost for
stored ton)
Minor cost for elimination of losses of material (be for
pollution, condensation or alteration of the characteristics
of the same one).
Elimination of necessary costs of maintenance in the
conventional structures (that use covers of sheet and metals).
The speed with which these varied forms get up constitutes
also an important advantage (they can be constructed in a
period of between four and six months). Your execution does
not need any more space than that it will occupy the future
dome, without need of operation of machinery and workforce
in your exterior.
DIVERSITY OF GEOMETRIES
The system allows to adopt
solutions with very diverse geometries that solve a wide
variety of problems. The versatility, together with the
possibility of loading on the whole surface of the structure,
allows an ideal utilization of the surface in available
plant and to reduce the volume of the construction with a
maximum adjustment to the capacity of storage needed.
The most representative forms:
* Spheres and semispheres (reduced spheres and
highlighted spheres)
* Cylinders of vertical axis crowned generally by
spheres
* Elipsoides
* Cylinders of vertical axis
The disposition, in turn, can
settle also directly in the foundations or on other
architectural elements.
