REVERSIBLE, THERMO-ACOUSTIC PANEL FOR REVERSIBLE,
VARIABLE-GEOMETRY FORMWORK
This invention pertains to a reversible,
thermo-acoustic panel intended for variable-:
geometry formwork.
Notedly, a formwork is a structure used in the
building and construction trade to build the
reinforced concrete =works. It provides a casing
into which the additional concrete in the liquid
state is cast, after the reinforcement irons have
been properly positioned, where the concrete stays
until the=completion of the setting process and
after the cast has, once the hardening phase has
started, achieved such mechanical strength as to
guarantee the absorption of the stress which the
structure has to withstand soon after the formwork
itself has been taken apart.
Formworks can be made of several materials; in
particular, formworks are currently available,
which are made up of polystyrene foam panels made
by means of the technique generally referred to as
1
CA 02861147 2014-07-14
WO 2012/095885 PCT/1T2012/000010
Insulated Concrete Form (ICE'), as well as of their
respective spacing connectors, which are disposable
items needed for the assembling and internal
blocking of the various aforesaid panels making up
the shuttering mould of a reinforced concrete wall.
In particular, the existing polystyrene panels
feature, along their upper and lower edges, a
plurality of engaging teeth and/or corresponding
,recesses suited to allow several such panels to be
connected by stacking. The arrangement of such
known teeth and recesses makes, however, it
possible to connect such panels by stacking in
mutually co-planar or orthogonal positions, whereas
as regards their mutual connection at different
angles, special connectors shall be used, which
require some time in order to be installed.
Moreover, all of the formwork systems
featuring polystyrene foam panels pose serious
transpiration problems, which may lead to building
reinforced concrete construction structures that
will, especially in case of civil buildings, give
rise to the well-known causes of SBS (Sick Building
Syndrome).
Furthermore, the "disposable" formwork systems
featuring polystyrene foam panels, generally
2
CA 02861147 2014-07-14
WO 2012/095885
PCT/1T2012/000010
referred to by the term "Insulated Concrete Form"
(ICF), of American or Canadian origin, still pose
sound-proofing problems since they are not able to
adequately break and dissipate the noise from the
outside.
Thus, the aim of this invention is to solve
the above-mentioned problems relative to the older
"Insulated Concrete Form" (ICF) method, by
providing a reversible, thermo-acoustic panel for
thermo-acoustic, disposable variable-geometry
formwork, which will make it possible to connect
several panels themselves by stacking, both in
mutually co-planar or orthogonal positions and in
mutually sloping positions.
One further aim of this invention is to
provide a .reversible, thermo-acoustic panel for
thermo-acoustic, "disposable" variable-geometry
formwork, equipped with lock-in profiles that will
make it possible to insert junction bridles both
inside and outside the formwork featuring multiple
pitches of 1.25 cm and 2.5 cm.
One further aim of this invention is to
provide a reversible panel for thermo-acoustic,
"disposable" variable-geometry formwork, which will
be able to create several formworks joined to one
3
CA 02861147 2014-07-14
WO 2012/095885 PCT/1T2012/000010
another through variable sections, in order to
contribute either structurally joint or separated
from one another according to calculation needs.
Furthermore, one aim of this invention is to
provide a reversible, _thermo-acoustic panel for
thermo-acoustic, "disposable" variable-geometry
formwork, equipped with lock-in profiles that will
make it possible to insert elements of the IPE or
"T" type as well as the assembling, inside and/or
outside, of ventilated walls or any other panel, by
guaranteeing the structural strength thereof even
in seismic areas.
One further aim of this invention is to
provide a reversible, thermo-acoustic panel for
thermo-acoustic, "disposable" variable-geometry
formwork, equipped with lock-in profiles that will
make it possible to insert any one structural
element of the ICF systems available on the market,
and also the various profiles made of steel alloy,
aluminum and structural fibre-composite plastics
produced especially for structural needs, with no
shape constraint at all.
One further aim of this invention is to
provide a reversible panel for thermo-acoustic,
"disposable" variable-geometry formwork, equipped
4
CA 02861147 2014-07-14
WO 2012/095885
PCT/1T2012/000010
with lock-in profiles that will make it possible to
insert any one structural element, that is to say,
oblong profiles made of steel alloy, aluminum and
structural fibre-composite plastics produced
especially for structural needs, with no shape
constraint at all, including reticular brackets to
be fitted as a constraint to the profiles
themselves, both at the bottom and the top.
Moreover, one further aim of this invention is
to provide a reversible, thermo-acoustic panel for
thermo-acoustic, "disposable" variable-geometry
formwork, which will make it possible to facilitate
the transpiration process inside the formwork
itself.
Furthermore, one aim of this invention is to
provide a =reversible, thermo-acoustic panel for
thermo-acoustic, "disposable" variable-geometry
formwork, which will make it possible to obtain
better sound-proofing of the formwork itself during
the entire service life thereof.
The above and the other aims and advantages of
the invention, as detailed in the description
hereafter, will be obtained by means of a
reversible, thermo-acoustic panel for reversible,
thermo-acoustic "disposable" variable-geometry

formwork, like the one described under claim 1.
Preferred embodiment designs and original variants
of this invention will be the object of the
relevant claims.
It is obvious that a number of variants and
modifications can be made to the described items
(e.g. variants and modifications concerning the
dimensions, that is to say, height, length and
thickness, and also the shape, as well as the
arrangements and the parts performing similar
functions) without departing from the scope of

invention, in their operating configurations;

FIGURES 15 to 19 show perspective views of
other preferred embodiments of the reversible
thermo-acoustic panels referred to in the present
invention, in their operating configurations.
By referring to the Figures, you can notice
that the reversible, thermo-acoustic panel 1
intended for reversible, thermo-acoustic
"disposable'! variable-geometry formwork, as
referred to in the present invention, is made up of
a vertical body 3 featuring one upper surface 5 and
one lower surface 7, both of them delimiting such
body 3, said upper surface 5 being equipped with a
plurality of engaging teeth 9 and/or engaging
recesses 10, and said lower surface 7 being
equipped with a plurality of such engaging teeth
and/or such engaging recesses 10 corresponding with
such engaging teeth 9 and/or engaging recesses 10

=
of upper surface 5.
As you can notice in FIGURE 5 in particular,
such plurality of engaging teeth 9 and/or engaging
recesses 10 is geometrically arranged in accordance
with a grid made up of the crossing between one
first distribution mode and one second distribution
mode relative to said teeth 9 and/or recesses 10:
in particular, the first distribution mode consists
of a plurality of first rows 11 of such teeth 9
and/or recesses 10 placed side by side in parallel
and also inclined by an angle a relative to the
longitudinal plane L-L of panel 1, such angle a
being preferably equal to 450
.
Furthermore, the second distribution mode
consists of a plurality of second rows 13 of such
teeth 9 and/or recesses 10 placed side by side in
parallel and also perpendicular to the longitudinal
plane L-L of panel 13, such second rows 13 being
mutually offset by at least the width of one such
tooth 9 and/or recess 10.
The reversible, thermo-acoustic panel 1
referred to in the present invention and described
above will therefore make it possible to connect
several panels 1 themselves by stacking, by locking
together the engaging teeth 9 and/or the recesses
9
CA 02861147 2014-07-14
WO 2012/095885
PCT/1T2012/000010
of the respective upper surfaces 5 and lower
surfaces 7 both in mutually co-planar or orthogonal
positions and in positions mutually inclined by the
aforesaid angle a: please note that if a = 450
,
5 panels 1 can be stacked onto one another in
parallel by subtending 45 angles among the
respective longitudinal planes L-L.
In addition, vertical body 3 may be equipped
with a plurality of first all-purpose lock-in
m profiles 15, preferably featuring a male or female
dovetail shape, suited to make it possible to
connect the reversible, thermo-acoustic panel 1
referred to in the present invention with any other
structural element needed for assembling a
reversible, thermo-acoustic "disposable" variable-
geometry formwork, such as, for instance, spacing
connectors, other panels 1 or made from known
methods, ventilated panels, junction bridles, and
so on, usually employed in the building and
construction trade. Please note that such first
all-purpose lock-in profiles 15 are productively
arranged preferably in a vertical direction, on at
' least both of the side walls of body 3 in such a
manner that the aforesaid structural elements can
be connected both inside and outside to the
CA 02861147 2014-07-14
WO 2012/095885 PCT/1T2012/000010
reversible, thermo-acoustic "disposable" variable-
geometry formwork made up of such reversible
thermo-acoustic panels 1.
Still more preferably - and in order to allow
full reversibility of the panel 1 referred to in
the present invention - at least one first wall of
body 3 is equipped with a plurality of first all-
purpose lock-in profiles 15 featuring a male
dovetail shape, whereas the second wall of body 3
opposite the first one is equipped with a
corresponding plurality of first all-purpose lock-
in profiles 15 featuring a female dovetail shape,
so as to allow co-planar connection of several
panels 1 referred to in the present invention,
without having to use other external connecting
elements. Thus, by connecting two or several
reversible thermo-acoustic panels 1 referred to in
the present invention with one another and, if
necessary, by connecting also other layers made of
different materials (such as, for instance, bricks,
shards, stone, and so on) with one another, the
formwork wall thickness can be increased and, also,
an increase can be achieved in the noise breaking
along the junction lines among such reversible
thermo-acoustic panels 1.

WO 2012/095885 PCT/1T2012/000010
In addition, the vertical body 3 may be
equipped with a plurality of second lock-in
profiles 17, the latter too being preferably
arranged in a vertical direction, suited to make it
possible to insert elements of the IPE or "T" types
19. Obviously, such elements 19 may be made of any
one material suitable for the purpose, such as, for
instance, steel, another metal or plastic
materials. As an alternative - and in order to
obtain significant weight reduction - such elements
19 may be made of a composite material such as, for
instance, carbon fibre.
In addition, at least the lower surface 7 of
body 3 of panel I referred to in the present
invention may be equipped with at least one first
transpiration groove 21 parallel with the
longitudinal plane L-L, which will make it possible
to form a transpiration grid when several panels I
referred to in the present invention are stacked
onto one another. Obviously, it can be anticipated
that also the upper surface 5 of body 3 of the
reversible, thermo-acoustic panel 1 referred to in
the present invention will be equipped with at
least one second transpiration groove 23 parallel
with the longitudinal plane L-L, pursuing a similar
12
CA 02861147 2014-07-14
WO 2012/095885
PCT/1T2012/000010
technical aim.
The vertical body 3 (obviously featuring
varying shapes, thicknesses and forms to adapt to
the various building and construction requirements
known in the building trade) shall preferably be
made of polystyrene foam suitable for use according
to the Insulated Concrete Form (ICF) method:
obviously, it can be anticipated that the vertical
body 3 will be made of any other material (which
may be a plastic one) suitable for the purpose,
without therefore departing from' the scope of
protection of this invention.
Furthermore, the body 3 of the reversible,
thermo-acoustic panel 1 may obviously feature any
one shape relative to its plan other than the
essentially rectangular one shown in FIGURES 1 and
2. In fact, as you can notice in FIGURE 6 by way of
example, the reversible, thermo-acoustic panel I
referred to in the present invention may be adapted
to an angular element, such that it will connect
with other thermo-acoustic panels 1 by means of the
respective lock-in profiles and also determine the
final closing of a reversible, thermo-acoustic
"disposable" variable-geometry formwork.
Obviously, as you can notice in FIGURES 7 and
13
CA 02861147 2014-07-14
WO 2012/095885 PCT/1T2012/000010
8 by way of example, the mutual connection and/or
the stacking of a plurality of reversible thermo-
acoustic panels 1 referred to in the present
invention make it possible to make, in a simple,
cost-effective, quick and convenient manner, any
one formwork 30 featuring the desired dimensions
and shapes (even complex ones).
Furthermore, by thus connecting two or several
panels 1 referred to in the present invention with
one another and, if necessary, by connecting also
other layers made of different materials (such as,
for instance, raw bricks, shards, stone, and so on)
with one another, the thickness of the walls of
reversible, thermo-acoustic "disposable" variable-
geometry formwork 30 can be increased and, also, an
increase can be achieved in the noise breaking
along the junction lines among such panels 1.
In addition, the vertical body 3 may be
equipped with a plurality of surface score lines
arranged by multiple pitches, in order to be able
to be partitioned to measure by mere manual effort.
FIGURES 9 to 12 and 15 to 19 show perspective
views of other preferred embodiments of panels
referring to this invention, in their operating
configurations. These Figures show two pairs of
14
CA 02861147 2014-07-14
WO 2012/095885 PCT/1T2012/000010
panels 1, placed side by side and separated by a
plurality of brackets 80 and a plurality of spacers
82, both such brackets 80 and connectors 82 being
supported by a plurality of connectors 81 and also
being suited to support respective reinforcement
irons 84. FIGURE 16 shows, moreover, a
configuration featuring new conical supports 86 for
orientation and diagonal arrangement of irons 84.
Finally, FIGURES 13 and 14 show perspective
views of an application relative to the inventive
reversible, thermo-acoustic panel 1 for the
ornamental, monolith capitals 100, the latter being
preferably made of polystyrene foam, too.
