The present embodiment relates to the field of prefabricated houses, and more
particularly relates to the modular prefabricated houses.
BACKGROUND OF INVENTION
5 Prefabricated houses have been in use from a long time. Prefabricated houses
include a plurality of modules that are joined together to give a proper structure of
a building. Prefabricated houses also include areas such as, but not limited to, a
bedroom, a kitchen, a bathroom, and a stair.
Traditionally, the prefabricated homes were designed at the factory, however, a lot
10 of work was done at the construction site. The work at the construction site is timeconsuming and expensive since many workers must be hired to finish the interiors.
Also, the electricity and the sanitation fittings are carried out at the site leading to
an increased cost. Also, the quality of the houses may vary depending on the
workers at every construction site.
15 Later, the prefabricated homes were designed wherein most of the work was done
at the factory and the modules were transported as a whole. This leads to an
increased cost in the transportation as a single module will require one
transportation vehicle and therefore, the multiple modules will require
transportation vehicles accordingly. Also, the electricity and the sanitation fittings
20 are visible and are installed at the site and therefore, the cost further increases.
The existing prefabricated homes includes many disadvantages vis-à-vis
prefabricated homes are not wind, earthquake and termite resistant, higher cost due
3
to transportation and working labour, increased risk of damage during transport,
requires civil work and use of cement etc for the construction.
Therefore, there is a need of a prefabricated house wherein the house is completely
designed with the electrical fittings and sanitation at the factory and requires
5 minimum installation at the site. Further, there is a need of the prefabricated house
that can be easily transported for reducing the transportation costs.
SUMMARY OF INVENTION
As mentioned, there is a need of a prefabricated house that can be constructed at a
factory and can be easily transported without any damage to the construction site.
10 In an aspect, a method of constructing/installing a prefabricated house is provided,
The method of constructing/installing the prefabricated house includes the
following steps: assembling of a plurality of modules having an electrical and a
sanitation fitting to form a prefabricate house, wherein the plurality of modules
includes a plurality of panels; dis-assembling the plurality of panels for the easy
15 transport, wherein the plurality of panels includes a wall panel, a roof panel and a
floor panel; transportation of the wall panel, the roof panel, and the floor panel at
the construction site; and re-joining of the wall panel, the roof panel, and the floor
panel at the construction site to form the prefabricated house, wherein the electrical
wires of a plurality of panels are joined to form an electrical circuit.
20 The plurality of panels includes a plurality of layers. The plurality of layers includes
a rectangular frame, an insulating layer, a vegetation board, a waterproofing layer
and a wooden cladding. The rectangular frame of light gauge steel has a bar of
4
heavy steel at a plurality of sides of the rectangular frame. The rectangular frame is
configured to provide structural stability to the prefabricated house. The insulating
layer covers the rectangular frame and provides insulation from extreme weather
conditions. The vegetation board is placed at the longitudinal sides of the
5 rectangular frame and provides rigidity to the prefabricated house. The
waterproofing layer is applied at a side of the frame that is exposed to the outside
environment to prevent the plurality of panels from water and moisture. The
wooden cladding is coated with a weather-proof oil and is placed at the longitudinal
sides of the rectangular frame to provide aesthetic value to the prefabricated house.
