PROVISIONAL PATENT APPLICATION
INVENTOR: BEN DEVINO
FORMWORK AND REINFORCING TO BUILD NEW COLUMNS INSITU
DESCRIPTION OF THE INVENTION
This invention is a formwork to build a concrete column to support an overhead
load and said column to rest on a foundation footing, or pier or other base
structure, so that said formwork acts both as a confining member to receive
the
poured concrete and as a strengthening member.
This invention is manufactured by producing a cylindrical cardboard outer
layer
of various thickness of cardboard and various diameters and length, lined with
varying layers of high tensile strength, high modulus Fiber Reinforced
Plastic.
The manufacturing process will require incorporating the existing
manufacturing
process of producing cylindrical cardboard forms for confining the space
within
which new concrete columns are poured, together with a new process that will
laminate layers of Fiber Reinforced Plastic fibers of glass, carbon, aramid or
basalt to the inner lining of the cardboard formwork.
The finished product will not only have the confining property of a typical
form
but will have a large capability to provide external reinforcement to the
newly
poured and cured column.
The advantage of this system will be to reduce the amount of internal
reinforcement required and to reduce the design size of the columns. This in
turn reduces dramatically the weight of the structure, thus reducing the
weight
on the foundation, which then in turn reduces the overall cost of building the
structure.
