Description
BACKGROUND OF THE INVENTION
[0001] The present invention refers to a disposable casing for
thermally insulated walls in reinforced concrete.
[0002] In the field of the construction industry in general,
disposable casings for thermally insulated walls in reinforced
concrete are well-known, comprising two polystyrene panels which
face each other and which are limited from the outside by
respective lateral surfaces, and at least two casing spacers which
are interposed between the two polystyrene panels themselves at a
determined distance from each other.
[0003] Casings of the kind which have been described above may be
mutually and speedily connected to each other in order to make up a
structure, which is suitable for receiving a jet of cement within
its interior, and once the cement has set it is capable of
guaranteeing, in a single solution, both the cement's capacity for
mechanical resistance, as well as the polystyrene's capacity for
thermal insulation.
SUMMARY OF THE INVENTION
[0004] The aim of the present invention is to produce a disposable
casing for thermally insulated walls in reinforced concrete which,
while presenting a base structure of standard dimensions, will also
permit the production of different thermal insulation
capacities.
[0005] According to the present invention a disposable casing for
thermally insulated walls in reinforced concrete will be
produced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0015] With reference to FIGS. 1 and 2, the number 1 indicates a
disposable casing for thermally insulated walls in reinforced
concrete in its entirety.
[0016] The casing 1 presents an longer longitudinal axis A, and
comprises two main panels 2, which are made of polystyrene,
presenting a standard thickness, and which are arranged facing and
parallel to each other and to the axis A.
[0017] The term "standard thickness" is herein taken to mean the
thickness which is commonly adopted for this kind of panelling
with, however, the difference that, in the casing 1 which is the
subject of the present invention, the two panels 2 might not
present the same thickness for reasons which shall be explained in
the following description.
[0018] The panels 2 are delimited towards the outside of the casing
1 by respective lateral surfaces 2e, while they are delimited
towards the inside of the casing 1 by respective lateral surfaces
2i which define a compartment 6 which is suitable for being filled
with cement.
[0019] In addition, each panel 2 presents a preferably
parallelepiped shape, and is further delimited by an upper surface
2s and by a lower surface 2f, which are parallel to each other and
which are transverse to the relative surfaces 2i and 2e.
[0020] In addition, the casing 1 comprises two or more casing
spacers 3 which in turn each comprise two respective intermediate
slats 31, and two anchoring portions 32, which are assembled,
preferably but not necessarily, by means of co-moulding with the
panels 2, and which are arranged at opposite ends of each pair of
slats 31. The anchoring portions 32 face the interior of the
compartment 6, and may be rigidly connected to the relative slat 31
in such a way as to form a single body together with the slat 31
itself as is illustrated in FIGS. 1 and 2, or, as is alternatively
illustrated in FIGS. 3 and 4, may be provided with respective pairs
of coupling tracks 33 for rapid coupling with the relative slat 31
as well as to permit the "in situ" assembly of the casing 1, or, as
is alternatively illustrated in FIGS. 5 and 6, may be provided with
respective pairs of hinges 34 for relative rotation with the
relative slats 31 and to permit the collapse of the casing 1 itself
into a transport configuration.
[0021] In addition, the casing 1 comprises a supplementary panel 5
which is arranged abutting an external lateral surface 2e of a main
panel 2 and a connecting component 7 which is interposed between
the supplementary panel 5 and the relative main panel 2 in order to
render the supplementary panel 5 and the relative main panel 2
themselves integral in relation to each other.
[0022] While the main panel 2 presents a standard thickness as has
already been specified above, the supplementary panel 5 presents,
instead, a thickness which may be adapted on the building site to
any installation demands and as a means of increasing both the
thermal insulation capacity of the casing 1, as well as permitting
the production of various thermal insulation capacities.
[0023] According to a form of embodiment which is not illustrated,
but which is easily understandable from the description so far
herein, the casing 1 may also be provided with two supplementary
panels 5 which are arranged abutting the outer surfaces 2e or the
relative main panels 2 and such supplementary panel 5 may also have
different thicknesses from each other in accordance with the levels
of thermal insulation which are to be reached according to
necessity.
[0024] In addition, the supplementary panel 5 may also be made of
the same material as the main panels 2, as it may also be made of
other materials which present different thermal insulation
capacities.
[0025] The connecting component 7 comprises a number of shaped
projections 71 which are integral with the supplementary panel 5
and which are arranged parallel to each other and transverse to the
axis A, and, for each shaped projection 71, a respective housing 72
with undercuts which are obtained through the outer surface 2e of
the relative main panel. Alternatively, the arrangement of the
projections 71 and of the housings 72 may be inverted in relation
to what has just been described.
[0026] In particular, each shaped projection 71 is defined by a
respective dovetailed moulding which extends for an entire height
of the supplementary panel 5, while the relative housing 72 extends
from a surface 2s to a surface 2f and presents a shape which is
complementary to the relative projection 71 and is such as to
permit the connection of the panel 15 to the panel 2 by means of
reciprocal sliding without any successive consequent possibility
whatsoever of detachment, or of any separation in a transverse
direction of the surface 2e.
[0027] The supplementary panels 6 which have been described above
present the advantage of being able to calibrate the thermal
insulation capacity of the casing 1 directly on site and in
accordance with local weather and climate conditions without the
need to vary the thickness of the main panels 2 with obvious
positive consequences on the production costs of these products, as
well as on the standardisation of the latter.
[0028] It is obvious from the foregoing description that in the
case that the casing 1 is provided with a single supplementary
panel 5, the relative panel 2 will present a thickness which is
greater than the other panel 2 in that it is able to contain the
housings 72, while, whenever the casing 1 is provided with two
supplementary panels 5, both the panels 2 can present the same
thickness.
[0029] AS stated above, FIGS. 3 and 4, like FIGS. 5 and 6,
illustrate different connection methods between the two panels 2 of
the casing 1, which, in the shape of its basic embodiment, provides
for the use of spacers 3 which are produced in a single piece,
while in the alternative form of embodiment which is shown in FIGS.
3 and 4 it provides for the use of spacers which are detachable
transverse to the axis A from the respective anchoring portions by
means of the relative tracks 33 permitting the supply of the casing
1 in an unassembled configuration, and in the alternative form of
embodiment which is shown in FIGS. 5 and 6 it provides for the use
of spacers 3 in which, between the slats 31 and the anchoring
portions 32, hinges 33' are arranged to permit the supply of the
casing 1 in a collapsed condition with the panels 2 arranged one
abutting the other.
[0030] FIGS. 7 and 8 illustrate a casing 1' which is substantially
similar to the casing 1, from which the casing 1' differs due to
the fact that the connecting component 7 is defined by a layer 7'
of adhesive material which is interposed between the main panel 2
and the relative supplementary panel 6 in such a way as to stick
the latter to the former in order to render them integral in
relation to each other.
[0031] The layer 7' may be used exclusively for the connection of a
supplementary panel 5 to the relative secondary main panel 2, or,
according to need, may also be used together with the projections
71 which have been described above.
