[0001] The present invention relates to an apparatus for on-site production of components
for concrete building.
[0002] Examples of such cementitious components or artefacts can be slabs, panels, curbs,
urban building components of different shape and size, and the like.
[0003] The present invention is used in the construction field, for example in the field
of prefabricated buildings, where various concrete components, in particular panels,
are assembled together to form living spaces, storage spaces and the like.
[0004] As is known, the production process of components for concrete building is characterised
by the use of large quantities of materials and the use of particularly bulky and
expensive machinery which are difficult to transport comfortably from one production
site to another. For these reasons, the building components are usually manufactured
in a single production site and only subsequently transported to the place where they
are assembled together, for example to form pre-fabricated buildings.
[0005] Such a production and transport method is particularly inconvenient and impracticable
in low-industrialised countries such as the countries of Africa.
[0006] A first difficulty encountered in such countries is usually that of geographic conformation.
In fact, in such countries, the connections between different places are particularly
difficult due to the scarce infrastructure and the roughness of the territory. The
transport of materials and machinery suitable for the creation of components is in
fact difficult and expensive.
[0007] This implies an increase in construction times and the necessary resources.
[0008] A second difficulty is also linked to the preparation of a suitable and practical
site for carrying out the concrete pouring.
[0009] Very often, in fact, in less industrialised countries there is difficulty installing
a suitable structure for carrying out the pouring to create the components in a reliable
and fast manner.
[0010] A further difficulty is given by the storage of the components made and waiting for
use.
[0011] As is known, in order to be able to use a concrete component, after pouring it is
necessary to wait for a period of at least partial drying of the latter. More in detail,
it is best for the concrete to undergo a first drying within the moulds in which it
has been poured to form a component. Subsequently, the concrete component is extracted
so as to undergo a second drying so that the component has the correct mechanical
properties.
[0012] This implies the need to have adequate spaces (in terms of size but also in terms
of environmental conditions) in which to carry out at least the first drying.
[0013] A further difficulty arises from the fact that in less industrialised countries,
it is difficult to find a highly specialised workforce capable of best exploiting
specific innovative technologies.
[0014] The object of the present invention is thus to provide an apparatus for on-site production
of components for concrete building capable of overcoming the prior-art drawbacks
which have emerged.
[0015] A further object of the present invention is therefore to provide an apparatus for
on-site production of components for concrete building which allows to produce the
components in the same place where they must be assembled, i.e., which allows a decentralisation
of the production of such products.
[0016] A further object of the present invention is therefore to provide an apparatus for
on-site production of components for concrete building which allows to reduce the
time and the costs related to the transport of the concrete products and components.
[0017] A further object of the present invention is therefore to provide an apparatus for
on-site production of components for concrete building which are easy to use even
by low-skilled workers.
[0018] A further object of the present invention is to provide an apparatus for on-site
production of components for concrete building which allows to avoid having to build
on-site ad hoc structures to perform the pouring of concrete and/or to allow the latter
to dry once poured.
[0019] A further object of the present invention is to provide an apparatus for on-site
production of components for concrete construction which allows to reduce the costs
and production times of the components themselves.
[0020] The specified technical task and the specified aims are substantially achieved by
an apparatus for on-site production of components for concrete building comprising
the technical features set forth in one or more of the appended claims. The dependent
claims correspond to possible embodiments of the invention.
[0021] Further features and advantages of the present invention will become more apparent
from the following indicative, and hence non-limiting, description of an apparatus
for on-site production of components for concrete building.

[0023] With reference to the appended drawings, 100 denotes an apparatus for the on-site
production of components for concrete building, such as slabs, curbs and the like,
according to the present invention.
[0024] In accordance with an aspect of the present invention, the apparatus 100 can further
allow the production of components for construction in pre- compressed concrete.
[0025] The apparatus 100 comprises a box-like containing structure 10 suitable for conveying.
[0026] The term "suitable for conveying" means that the containing structure 10 is suitable
for being loaded onto a ship, a train, a truck, a helicopter and the like so that
the entire apparatus 100 is transportable to the place where it is intended to start
a production of the concrete components and, subsequently, a construction by means
of such components.
[0027] Preferably, the apparatus 100 has an overall weight comprised between 15 tonnes and
30 tonnes.
[0028] Even more preferably, the apparatus 100 has an overall weight comprised between 20
tonnes and 25 tonnes.
[0029] In the case of transport by helicopter, the apparatus 100 has a weight of about 21
tonnes.
[0030] In accordance with a possible embodiment, the containing structure 10 comprises a
container of standard dimensions, preferably of the 20', 40' or 45' type (the symbol'
indicates the unit of measurement feet).
[0031] Preferably, the container can be of the HCC High Cube Container type.
[0032] Advantageously, the use of the container contributes to making the entire apparatus
100 easily movable and handleable so as to be transported where necessary.
[0033] As shown in the accompanying drawings, the containing structure 10 defines a containing
volume "V" with preferably horizontal extension.
[0034] The containing volume "V" comprises a first subvolume "V1" and a second subvolume
"V2" placed alongside one another.
[0035] The apparatus 100 further comprises a support frame 20 housed in the first subvolume
"V1" and defining a plurality of support areas juxtaposed on one another along a vertical
stacking direction "Y".
[0036] That is, the support frame 20 defines a sort of shelving or vertical warehouse provided
with shelves one juxtaposed to the other vertically along the stacking direction "Y".
[0037] In accordance with an embodiment, the support frame 20 is a frame of lattice type.
[0038] Advantageously, the use of the lattice frame makes the entire apparatus 100 lighter
and more easily transportable to the place where it is intended to start the production
of the components for building.
[0039] Preferably, the support frame 20 is formed by a plurality of rectangular-section
pipes made of metal material, preferably iron or stainless steel, and welded together
by means of MIG (Metal-arc Inert Gas) welds.
[0040] Even more preferably, such pipes are surface treated to preserve the mechanical properties
thereof.
[0041] In a preferred embodiment, the support frame 20 is sized to be inserted to measure
in the containing structure 10.
[0042] As shown in the accompanying drawings, in fact, the support frame 20 is adherent
to the walls of the containing structure 10 so that it is possible to best exploit
the containing volume "V".
[0043] As shown in the accompanying drawings, the apparatus 100 comprises at least two formworks
30a, 30b, 30c each configured to contain a preset quantity of concrete for forming
at least one respective component.
[0044] In the embodiment shown in the accompanying drawings by way of non-limiting example,
the apparatus 100 comprises three formworks 30a, 30b, 30c.
[0045] Each formwork 30a, 30b, 30c is slidably housable in a respective support area of
the support frame 20.
[0046] Preferably, each formwork 30a, 30b, 30c is slidably movable at least along an extraction
direction "E", preferably horizontal.
[0047] As shown in the accompanying drawings, each formwork 30a, 30b, 30c is slidably movable
to assume a storage configuration (figure 1A, 1B), in which the formwork 30a, 30b,
30c is inserted into the support frame 20, and an extraction configuration (figure
2), in which the formwork 30a, 30b, 30c is at least partially extracted from the support
frame 20.
[0048] In particular, as will be described in detail below, each formwork 30a, 30b, 30c
assumes the storage configuration when it is filled with liquid concrete so that the
latter can at least partially dry while the formwork 30a, 30b, 30c is placed inside
the containing structure 10. Each formwork 30a, 30b, 30c assumes the storage configuration
even when it is empty and must be filled with liquid concrete.
[0049] Advantageously, the presence of the support frame 20 allows a filling of the formworks
30a, 30b, 30c directly inside the apparatus 100 without the need to build ad hoc structures
or supports for filling the formworks 30a, 30b, 30c.
[0050] Advantageously, the presence of the support frame 20 allows a storage (at least during
a partial drying period) of the forming components within the formworks 30a, 30b,
30c without there being a need to create an ad hoc structure outside the apparatus
100.
[0051] According to an aspect of the present description, as shown in the accompanying drawings,
each formwork 30a, 30b, 30c is housed within a respective support area so as to have
a main dimension arranged along the extraction direction "E" and parallel to the main
dimension of the containing structure 10.
[0052] That is, each formwork 30a, 30b, 30c is housed within a respective support area so
as to act as a drawer or a removable shelf, along the extraction direction "E", for
the support frame 20.
[0053] As shown in figure 3, each formwork 30a, 30b, 30c has the shape of a tank, for example
a rectangular-section tank, with a bottom wall 31, a pair of side walls 32 opposite
each other and a pair of partitions 34 opposite each other.
[0054] As shown in the accompanying drawings, each formwork 30a, 30b, io 30c is housed within
a respective support area so as to have the side walls 32 arranged along the extraction
direction "E".
[0055] In accordance with an aspect of the present invention, the pair of side walls 32
is fixed, preferably welded, to the bottom wall 31.
[0056] In accordance with a further aspect of the present invention, the partitions 34 of
the pair of partitions are movable towards and away from each other along the extraction
direction "E" so as to vary a containing volume of the formwork 30a, 30b, 30c.
[0057] Advantageously, the possibility of adjusting the mutual position of the partitions
34, and therefore the dimensions and volume of the formwork 30a, 30b, 30c, allows
the apparatus 100 to be flexible and to produce different types of components.
[0058] Preferably, each formwork 30a, 30b, 30c is made of metal material and, even more
preferably, sheet metal.
[0059] In accordance with an aspect of the invention, each formwork 30a, 30b, 30c comprises
at least one indicator device (not depicted), for example a laser, configured to project
a filling diagram for the formwork 30a, 30b, 30c.
[0060] In detail, the indicator device is configured to identify the positioning regions
within the formwork 30a, 30b, 30c indicating the points where an operator, before
the concrete pouring, must position outlines (for example of box-like elements, wedges
or the like) so as to obtain a shaped component. If, for example, it is necessary
to make a component bearing, in a preset position (i.e., at a preset distance from
the external edges), a hole, the indicator device will project a diagram on the formwork
30a, 30b, 30c indicating the point where it is necessary to position an outline having
the form and size of the hole to be obtained. In such a situation, following the positioning
of the outline, the concrete can be poured in the formwork 30a, 30b, 30c obtaining
the desired perforated component.
[0061] Preferably, the outlines are magnetic so as to be able to reversibly but stably adhere
to the side walls 32a and/or the partitions 34 and/or the bottom wall 31 of the formwork
30a, 30b, 30c.
[0062] In accordance with a possible embodiment, on a partition 34, each formwork 30a, 30b,
30c comprises a feeding opening 32a and a cap 32b movable between a closing position,
in which it occludes the feeding opening 32a so as to prevent a leakage of the liquid
concrete contained in the formwork 30a, 30b, 30c, and an opening position, in which
it is distal from the feeding opening 32a to allow a filling of the formwork 30a,
30b, 30c with the concrete, as will be described in detail below.
[0063] Preferably, the feeding opening 32a is made on the partition 34 near the bottom wall
31 so as to fill the formwork 30a, 30b, 30c from below.
[0064] Advantageously, the fact of filling each formwork 30a, 30b, 30c from below prevents
a massive formation of air bubbles during pouring.
[0065] In accordance with an aspect of the present description, the apparatus 100 further
comprises liquid concrete feeding means 50 arranged at least in part in the second
subvolume "V2" and configured to dispense the preset quantity of concrete to each
formwork 30a, 30b, 30c while the latter is housed in the respective support area.
[0066] According to a further aspect of the present description, the feeding means 50 comprises
at least one pump 51.
[0067] The pump 51 is selectively connectable, by means of a feeding pipe 51a, preferably
flexible, to each formwork 30a, 30b, 30c housed in the first subvolume "V1", i.e.,
in the support frame 20, so as to dispense the preset quantity of concrete in the
formwork 30a, 30b, 30c.
[0068] More in detail, as shown in figure 5, to perform the filling of each formwork 30a,
30b, 30c housed in the support frame 20, the feeding pipe 51a is reversibly connected
to the feeding opening 32a of a first formwork 30a, 30b, 30c to dispense the preset
quantity of concrete therein. At the end of such dispensing, the feeding pipe 51a
is removed from the feeding opening 32a and the cap 32b is brought into the closing
position. Subsequently, the feeding pipe 51 a is connected to the feeding opening
32a of a second formwork 30a, 30b, 30c to perform the filling thereof by means of
the concrete.
[0069] The operations of removing and connecting the feeding pipe 51a to the feeding opening
32a of the formworks 30a, 30b, 30c are repeated for each formwork 30a, 30b, 30c housed
within the support frame 20 so that each formwork 30a, 30b, 30c is filled with the
liquid concrete.
[0070] In the preferred embodiment, the pump 51 is arranged in a fixed position.
[0071] In particular, as shown in the accompanying drawings, the pump 51 is housed within
the second subvolume "V2".
[0072] Preferably, the pump 51 is positioned so as to face the formworks 30a, 30b, 30c housed
within the respective support areas of the support frame 20, and in particular, facing
their feeding openings 32a.
[0073] Even more preferably, the pump 51 is supported on a protrusion obtained in the support
frame 20 so as to be positioned at a level from the ground equal to about half the
height of the support frame 20 itself (figure 5).
[0074] Such positioning is advantageous in that it allows the feeding pipe 51 a to comfortably
reach all the feeding openings 32a of the formwork 30a, 30b, 30c placed in the support
frame 20 without there being the need to lift or lower the pump 51 within the second
subvolume "V2".
[0075] As shown in figure 1A and 1B, the feeding means 50 further comprises a mixer or cement
mixer 52 arranged in the second subvolume "V2" and connected to the pump 51 by means
of a connecting pipe 54, preferably of the flexible type.
[0076] In such a situation, the liquid concrete processed by the mixer 52 is brought, through
the connecting pipe 54, to the pump 51 which selectively dispenses it, by means of
the feeding pipe 51a, to the formwork 30a, 30b to perform the filling thereof.
[0077] In the preferred embodiment, the mixer 52 defines a mixing chamber in which a cement
mixture is mixed to form liquid concrete.
[0078] In the preferred embodiment, shown in figure 6, the feeding means 50 further comprises
a feeding hopper 52a arranged above the mixer 52 and configured to allow an insertion
into the mixer 52 of the components of the cementitious mixture such as sand, gravel,
water and the like.
[0079] In such a situation, the liquid concrete is dispensed into the connecting pipe 54
so that it reaches the pump 51 and is dispensed to each of the formworks 30a, 30b,
30c.
[0080] As shown in figures 7A, 7B, the mixer or cement mixer 52 is operatively movable outside
the containing structure 10.
[0081] The possibility of moving the mixer or cement mixer 52 inside or outside the containing
structure 10, and in particular, from the second subvolume "V2", makes the apparatus
100 easily and conveniently transportable.
[0082] To further facilitate such movement, the mixer or cement mixer 52 is provided with
a lattice and/or box-like frame 53.
[0083] Advantageously, the lattice and/or box-like frame 53 allows to engage, for example
by means such as a forklift, crane or the like, the mixer or cement mixer 52 to easily
extract or retract it within the second subvolume "V2" without however excessively
weighing down the apparatus 100.
[0084] Alternatively, the apparatus 100 could provide, within the second subvolume "V2",
a framing configured to support the mixer or cement mixer 52. Such a framing is movable,
for example by means of hydraulic pistons, in an automated manner in extraction or
retraction from the second subvolume "V2" to extract or retract the mixer or concrete
mixer 52.
[0085] Advantageously, the movable framing allows the mixer or cement mixer 52 to be extracted
or retracted without the aid of forklifts, cranes or the like.
[0086] Advantageously, the movable framing allows the mixer or cement mixer 52 to be extracted
or retracted more safely, avoiding damage to the mixer or cement mixer 52 itself and
to the operators.
[0087] In accordance with an aspect of the present description, the apparatus 100 further
comprises a generator set 80 configured to electrically supply at least the pump 51.
[0088] Like the mixer 52, the generator set 80 is also configured to be arranged in the
second subvolume "V2".
[0089] Preferably, the generator set 80 is operatively movable outside the containing structure
10.
[0090] Therefore like the mixer 52, the generator set 80 can also be extracted from the
containing structure 10 when the apparatus 100 is in use or can be contained in the
containing structure 10 when the apparatus 100 is transported.
[0091] Preferably, the mixer 52 and the generator set 80, when they are both placed within
the second subvolume "V2", are mutually side by side.
[0092] As shown in the accompanying drawings, the generator set 80 is also provided with
a lattice and/or box-like frame 53.
[0093] Advantageously, the lattice and/or box-like frame 53 allows to engage, for example
by means such as a forklift or the like, the generator set 80 to extract or retract
it comfortably within the second subvolume "V2" without however excessively weighing
down the apparatus 100.
[0094] Advantageously, the lattice and/or box-like frame 53 also makes it possible to avoid
that, when the apparatus 100 is transported and the generator set 80 and the mixer
52 are both housed within the second subvolume "V2", the latter collide damagingly.
[0095] Alternatively, if the apparatus 100 provides the movable framing within the second
subvolume "V2", the generator set 80 could also be mounted therein so as to be moved
in an automated manner in extraction or retraction from the second subvolume "V2".
[0096] In use, therefore, the apparatus 100 is transported to the place where it is intended
to produce and assemble the concrete components.
[0097] During such transport, the formworks 30a, 30b, 30c, the generator set 80 and the
mixer 52 are housed within the containing structure 10 respectively within the support
frame 20 and within the second subvolume "V2".
[0098] Once the apparatus 100 is positioned, the generator set 80 and the mixer 52 are extracted
from the second subvolume "V2". In such a situation, gravel, sand and the like for
making the concrete are introduced, by means of the feeding hopper 52a, into the mixing
chamber where they are mixed to form liquid concrete.
[0099] Subsequently, such liquid concrete is sent to the pump 51 by means of the connecting
pipe 54. In such a situation, the feeding pipe 51a is connected to the feeding opening
32a of a first formwork 30a, 30b, 30c so that the liquid concrete can be dispensed
by the pump 51 to fill the formwork 30a, 30b, 30c itself.
[0100] At the end of the filling of the first formwork 30a, 30b, 30c, the feeding pipe 51a
is disconnected, the cap 32b is brought to the closing position to occlude the feeding
opening 32a and the pump 51 suspends the dispensing. Subsequently, the supply pipe
51 a is connected to the feeding opening 32° of a second formwork 30a, 30b, 30c and
the pump 51 is activated so as to feed the liquid concrete therein.
[0101] The aforesaid operations for connecting the feeding pipe 51a and for filling are
repeated for each formwork 30a, 30b, 30c housed in the support frame 20.
[0102] To ensure that the concrete components formed within the formworks 30a, 30b, 30c
are of good quality and are provided with the correct mechanical properties, the apparatus
100 comprises at least one vibrating support 60 selectively associated or associable
with one of the formworks 30a, 30b, 30c, in particular the bottom wall 31 of the formwork
30a, 30b, 30c, to generate a vibration of the formwork 30a, 30b, 30c when the latter
is housed in the respective support area.
[0103] In particular, the vibrating support 60 generates vibration on the formwork 30a,
30b, 30c when the latter has just been filled with liquid concrete so as to encourage
the exit of air contained therein.
[0104] As shown in figure 4, the vibrating support 60 is mounted on the support frame 20.
[0105] More in detail, the vibrating support 60 has four vertices defining respective anchoring
points "P1", "P2", "P3", "P4" of the vibrating support 60 to the support frame 20.
[0106] In a preferred embodiment, the vibrating support 60 has an extension, in plan, at
least partially overlapping each formwork 30a, 30b, 30c.
[0107] Preferably, the vibrating support 60 has an extension, along the extraction direction
"E" of the formworks 30a, 30b, 30c, comprised between 50% and 90% of the length of
the formworks.
[0108] Even more preferably, as shown in figure 3, the vibrating support 60 comprises an
elongated portion 60a of substantially rectangular shape and extending along the extraction
direction "E" of the formworks 30a, 30b, 30c. The vibrating support 60 further comprises,
near the ends of the elongated portion 60a, a first shaped portion 60b and a second
shaped portion 60c extending transversely to the elongated portion 60a and projecting
laterally therefrom to define the four anchoring points "P1", "P2", "P3", "P4" of
the vibrating support 60.
[0109] As shown in figure 3, in a preferred embodiment, each formwork 30a, 30b, 30c comprises,
on an outer surface of the bottom wall 31, an engagement structure 33 counter-shaped
to the vibrating support 60 to reversibly constrain the formwork 30a, 30b, 30c to
the vibrating support 30 so that they vibrate simultaneously.
[0110] That is, the outer surface of the bottom wall 31 of each formwork 30a, 30b, 30c and
the vibrating structure 60 are engageable with each other by means of a shape connection
so that the formwork 30a, 30b, 30c is made integral with the vibrating support 60
so as to vibrate together therewith.
[0111] Advantageously, the presence of the engagement structure 33 prevents that, during
vibration, there is relative movement between the formwork 30a, 30b, 30c and the vibrating
support 60 capable of causing a sliding of the formwork 30a, 30b, 30c on the vibrating
support 60 itself.
[0112] In use, therefore, once a formwork 30a, 30b, 30c is filled with the liquid concrete,
the vibrating support 60 is associated with the bottom wall 31 of the formwork 30a,
30b, 30c by means of the engagement structure 33 and is activated in vibration.
[0113] In accordance with an aspect of the present description, to abut against the bottom
wall 31 of the formworks 30a, 30b, 30c, the vibrating support 60 is slidingly movable
in the first subvolume "V1" along the stacking direction "Y".
[0114] In particular, the vibrating support 60 is configured to be arranged in a space left
free from a formwork 30a, 30b, 30c extracted from the first subvolume "V1" and to
abut below the formwork 30a, 30b, 30c so as to raise the latter and place it in vibration.
[0115] The vibrating support 60 is further configured to move vertically so as to actuate
a temporary support of the formwork 30a, 30b, 30c, as will be described in detail
below.
[0116] Preferably, the vibrating support 60 comprises lifting actuators 70, in particular
cylinders or chains, configured to move the vibrating support 60 along the support
frame 20 towards a formwork 30a, 30b, 30c to be vibrated or away therefrom at the
end of the vibration generating operation.
[0117] In the embodiment shown in figure 4, the support frame 20 comprises vertical rails
or guides 21 within which chains act to move the vibrating support 60 along the stacking
direction "Y".
[0118] Preferably, the vertical rails or guides 21 are isolated relative to the vibratory
movement of the vibrating support 60 so as to avoid damage to the support frame 20.
[0119] In the preferred embodiment, in order to perform a vibration of each formwork 30a,
30b, 30c containing liquid concrete, the support frame 20 is populated with formworks
30a, 30b, 30c starting from its top so that the vibrating support 60 can progressively
be arranged below each formwork 30a, 30b, 30c as they are housed in the support frame
20.
[0120] That is, by way of non-limiting example, a first formwork 30a, 30b, 30c is housed
within a respective support area near the top of the support frame 20 and the preset
quantity of concrete is dispensed by the pump 51. At the end of the dispensing, the
vibrating support 60 is slidingly moved vertically so as to abut against the bottom
wall 31 of the first formwork 30a, 30b, 30c. In such a situation, the vibrating support
60 is located in a free space of the support frame 20, i.e., in a support area of
a formwork 30a, 30b, 30c not occupied by any formworks 30a, 30b, 30c. In such a position,
the vibrating support 60 engages the formwork 30a, 30b, 30c thereabove, temporarily
supports it and causes a vibration thereof adapted to let the air exit from the concrete.
[0121] Subsequently, the vibrating support 60 rests the formwork 30a, 30b, 30c within the
support frame 20 again and disengages the formwork 30a, 30b, 30c moving away therefrom
along the stacking direction "Y".
[0122] Subsequently, a second formwork 30a, 30b, 30c is housed in the support frame 20 below
the first formwork 30a, 30b, 30c and is filled with concrete.
[0123] In such a situation, the vibrating support 60 is again activated to abut against
the bottom wall 31 of the second formwork 30a, 30b, 30c and cause the vibration thereof.
The operations of inserting the formworks 30a, 30b, 30c into the support frame 20,
the operations of filling the formworks 30a, 30b, 30c and the operation of moving
the vibrating support 60 are repeated for each formwork 30a, 30b, 30c which is progressively
inserted into the support frame 20 and filled with concrete.
[0124] At the end of filling the formworks 30a, 30b, 30c and the action of the vibrating
support 60 on each one thereof, the concrete begins its drying within the formworks
30a, 30b, 30c housed in the support frame 20.
[0125] In order to extract the concrete components from each formwork 30a, 30b, 30c and/or
in order to re-insert each empty formwork 30a, 30b, 30c within the support frame 20
to perform new concrete pourings, the apparatus 100 comprises an extractor device
40.
[0126] The extractor device 40 is configured to withdraw at least one formwork 30a, 30b,
30c from a respective support area by moving the formwork 30a, 30b, 30c at least along
an extraction direction "E" between the storage and extraction configurations.
[0127] In accordance with an aspect of the present description, as shown for example in
figures 1A-2, the extractor device 40 has a rest base 41, preferably made in the form
of two mutually parallel skids.
[0128] The extractor device 40 also has a vertically movable support platform 42 to be brought
to the level of a formwork 30a, 30b, 30c to be extracted (or possibly to the level
of a support area in which it is intended to insert a formwork 30a, 30b, 30c).
[0129] In use, in fact, the support platform 42 is lowered or lifted parallel to the stacking
direction "Y" so as to be arranged at a height equal to the height of the formwork
30a, 30b, 30c which is intended to be extracted (or inserted) from the support frame
20. In such a situation, during the extraction (or insertion), the formwork 30a, 30b,
30c is progressively slid onto the support platform 42, as will be described in detail
below.
[0130] Preferably, the support platform 42 comprises a pair of sliding partitions 42a, 42b
extending along opposite edges of the support platform 42 itself. The pair of sliding
partitions 42a, 42b is configured to guide a 17 formwork 30a, 30b so that the latter,
passing from the storage configuration to that of extraction or vice versa, does not
slide or deviate with respect to the extraction direction "E".
[0131] In accordance with an aspect of the present description, the extractor device 40
comprises, interposed between the support platform 42 and the rest base 41, a movement
mechanism 45 configured to raise or lower the support platform 42 so as to place the
latter at the level of the formwork 30a, 30b, 30c which is to be extracted (or possibly
insert within the respective support area).
[0132] Preferably, the movement mechanism 45 is made in the form of a scissor lift provided
with a plurality of actuators, for example hydraulic actuators, configured to allow
a lifting or lowering of the support platform 42.
[0133] Preferably, the actuators for the movement of the movement mechanism 45 are powered
by the generator set 80.
[0134] Alternatively, the actuators for the movement of the movement mechanism 45 are powered
by a dedicated motor.
[0135] To perform the actual extraction, and therefore to bring the formwork 30a, 30b, 30c
from the storage configuration to the extraction configuration, the extractor device
40 comprises a gripping hook 43 protruding from the support platform 42 and configured
to engage an edge of the formwork 30a, 30b, 30c.
[0136] The gripping hook 43 is slidably movable parallel to the extraction direction "E"
of the formworks 30a, 30b, 30c to extract a formwork 30a, 30b, 30c from the respective
support area and to transfer the formwork 30a, 30b, 30c onto the support platform
42.
[0137] The gripping hook 43 is also slidably movable parallel to the extraction direction
"E" of the formworks 30a, 30b, 30c to insert a formwork 30a, 30b, 30c within the respective
support area, transferring it from the support platform 42 to the support area itself.
[0138] In the preferred embodiment, the gripping hook 43 is slidably movable within a longitudinal
guide 44 obtained in a centre line of the support platform 42.
[0139] Preferably, the gripping hook 43 is slidably moved by means of a chain, a belt or
a ball screw extending within the longitudinal guide 44 and activatable by means of
a motor (for example by the same motor which starts the actuators of the movement
means 45) or by the generator set 80.
[0140] In use, therefore, when there is a need to extract a formwork 30a, 30b, 30c, the
movement means 45 is activated so as to bring the support platform 42 to the level
of the formwork 30a, 30b, 30c to be extracted (figure 1A, 1B).
[0141] Preferably, the support platform 42 is moved vertically so as to lie at the same
height as the bottom wall 31 of the formwork 30a, 30b, 30c to be extracted.
[0142] After the movement of the support platform 42, the gripping hook 43 is slid along
the longitudinal guide 44 approaching the edge, preferably the lower edge, of the
formwork 30a, 30b, 30c to be extracted and firmly engages the latter. In such a situation,
the gripping hook 43 is again slid, in the opposite direction relative to the previous
one, so as to drag the formwork 30a, 30b, 30c therewith, which is thus extracted from
the respective support area passing to the extraction configuration (figure 2).
[0143] During the extraction of the formwork 30a, 30b, 30c, the latter, as shown in figure
2, is progressively made to rest on the support platform 42 until the gripping hook
43 ends its sliding motion and the entire lower wall of the formwork 30a, 30b, 30c
is found resting on the support platform 42.
[0144] Following the positioning of the formwork 30a, 30b, 30c on the support platform 42,
the extractor device 40 can be moved away from the containing structure 10 and, possibly,
the support platform 42 can be lowered so as to be able to perform a removal of the
concrete component from the formwork 30a, 30b, 30c.
[0145] In accordance with a further aspect of the present invention, as shown in figure
7A, the extractor device 40 is configured to assume a collapsed configuration defining
a minimum encumbrance.
[0146] In such a situation, the first subvolume "V1" has, in a lower portion thereof arranged
below the support areas, a housing "A" intended for containing the extractor device
40 in the collapsed configuration.
[0147] That is, when there is no need to extract and/or move the formworks 30a, 30b, 30c
from the support frame 20, the extractor device 40 is brought into a collapsed configuration
and is inserted into the housing "A" below the support areas occupied by the formworks
30a, 30b, 30c.
[0148] Advantageously, the possibility of inserting the extractor device 40, when not in
use, within the housing "A", allows to limit the dimensions of the apparatus 100,
making it particularly manageable and easy to transport towards the place where concrete
components must be produced.
[0149] In accordance with a possible embodiment shown in figures 7A, 7B, the housing "A"
extends, along the extraction direction "E", entirely below the support areas and
at least partially below the second subvolume "V2".
[0150] Preferably, the housing "A" extends to below the pump 51 which is thus raised as
aforesaid.
[0151] In use, therefore, during the transport of the apparatus 100, the extractor device
40 as well as the generator set 80 and the concrete feeding means 50 are contained
within the containing volume "V" delimited by the support structure 10.
[0152] Following the positioning of the apparatus 100 in the place where it is intended
to perform the production of the concrete components, the feeding means 50 and the
generator set 80 are extracted from the second subvolume "V2" while the extractor
device 40, which is in a collapsed configuration, is extracted from the housing "A".
[0153] Preferably, the extraction occurs by sliding the extractor device 40 parallel to
the extraction direction "E".
[0154] Even more preferably, the rest base 41 of the extractor device 40 is slidable, in
particular slidably fitted to the support frame 20, to move the extractor device 40
in extraction from the first subvolume "V1" to an operating position that is suitable
for extracting the formworks 30a, 30b, 30c from the support areas.
[0155] In particular, in the operating position, the extractor device 40 is aligned with
the containing structure 10 in the extraction direction "E" and facing the support
frame 20 where the formworks 30a, 30b are housed.
[0156] In such a situation, the movement means 45 can be activated so as to move the support
platform 42 vertically to bring it to the level of a formwork 30a, 30b, 30c to be
extracted (figure 1A, 1B, 7B), for example to the level of a formwork 30a, 30b, 30c
in which the liquid concrete has already been dispensed by the pump 51.
[0157] Following the positioning of the support platform 42, the gripping hook 43 is moved
to approach the edge of the formwork 30a, 30b, 30c and firmly engage such an edge
(figure 2).
[0158] Subsequently, the gripping hook 43 is moved in the opposite direction to the previous
one so as to drag the formwork 30a, 30b, 30c therewith, which is extracted from the
respective support area and is progressively arranged on the support platform 42.
During the extraction, the pair of sliding partitions 42a, 42b guides the formwork
30a, 30b, avoiding its slippage with respect to the extraction direction "E".
[0159] At the end of the extraction of the formwork 30a, 30b, 30c, the extractor device
40 is moved, by means of the rest base 41, away from the containing structure 10 and,
possibly, the supporting platform 42 is lowered vertically so as to allow an extraction
of the concrete component from the formwork 30a, 30b, 30c.
[0160] In accordance with an aspect of the present invention, the apparatus 100 could comprise
a plurality of containing structures 10 each suitable for housing machinery and/or
equipment suitable for the creation of concrete components.
[0161] In particular, the apparatus 100 could comprise a containing structure 10 for a washing
and sieving plant. The apparatus could further comprise a containing structure 10
for a crushing and sorting plant.
[0162] The present invention achieves the proposed objects, eliminating the drawbacks that
have emerged from the known art.
[0163] In particular, the apparatus 100 is compact and easily manageable and therefore particularly
suitable to be transported for the production of concrete components where necessary.
[0164] The apparatus 100 is complete in that it allows to create the concrete, to pour the
concrete in the formworks 30a, 30b, 30c, to store the formworks 30a, 30b, 30c for
drying the concrete and to move such formworks 30a, 30b, 30c so as to extract the
components obtained without the need for external interventions and/or the aid of
further devices/structures outside the io apparatus 100.
[0165] The apparatus 100 is highly easy to use, reducing human error during the creation
of the cement components. Therefore, such an apparatus 100 is particularly suitable
for use in less industrialised places where the workforce is scarcely specialised.
[0166] That is, the apparatus 100, while comprising in itself all the functions of a factory
for cementitious artefacts, is simple and convenient to transport where there is a
need. Furthermore, it is easy to use.
[0167] The possibility of filling the formworks 30a, 30b, 30c within the apparatus 100 and
the possibility of storing the formworks 30a, 30b, 30c within the apparatus 100 itself
allows to protect the concrete components from the external environment while preserving
the mechanical qualities thereof.
