INTEGRATED FORMWORKS
This invention relates to the technology of formworks for
placing concrete in elements, structures, etc., in all kinds of
- buildings: highrise, residential, industrial, public, bridges, etc.
In the existing technology the formworks for placing concrete are
made mostly of wood, steel, aluminium, etc. The wood forms are
made mostly of:
- panels comprising boards, and pieces 2x4, etc.
- panels of plywood strengthened with studs 2x4, etc.
- the widths and lengths may vary from one foot to many feet.
/O The steel formworks are made mostly of:
- panels (plates) with standard dimensions of several feet
reinforced with steel beams.
- flying formworks build in sets fitting the dimensions of whole
walls and floor slabs.
- self-erecting formworks for high structures like silo, chimney.
The aluminium formworks are similar to those made of steel.
All these kinds of formwork have many disadvantages:
~ - the cost of labour and materials for producing a formwork unit
is high because it requires high standards for processing it:
20 very costly materials and highly qualified labour.
- the cost of erecting formworks made of wood, steel, aluminium
for a structure is high because:
The high qualified labour required.
2120957
Many improvisations required.
The curve or other complicated shapes are time consuming.
Dismantling, cleaning and maintenance are time consuming.
The rhythm of erection is slow.
After dismantling the surface of the concrete needs many
corrections.
The inventive idea is a product called INTEGRATED FORMWORK
that is a thin plate of concrete or of other material that is
used as a formwork for placing concrete. The shape of this
product may be plane, curved or any three dimensional shape
according to necessities. In the process of its production
this plate gets, in most cases, a finished surface. The width
and length of this plate may be equal to those of a whole
element: wall, floor slab, etc. After placing the concrete in
this formwork the INTEGRATED FORMWORK remains integrated
permanently in the element or in the structure, etc.
The advantages of this invention are:
- the labour is cheap because all the operations may be
performed by low qualified workers.
- 2~ - the material, usually concrete, is cheap and is included
in the element or the structure so there is no waste.
- the fact that the surfaces of this formwork are already
finished is saving time and money, eliminating further
work.
~b ~
2120957
- the erection of the Integrated formwork is very simple and
fast.
The summary of the advantages:
- eliminates some operations: dismantling the formworks and
- maintenance works.
- repairing the surface of the concrete.
- performing the finishing works on concrete surface.
- it is very easy to place in the elements (walls, etc) all
kinds of materials (insulations, piping, cables, etc),
devices, inserts, etc.
- the rhythm of erection of a structure is fast therefore
the time is shortened.
- the works on the exterior side of the structure is
eliminated almost completely.
All these advantages lower the costs.

Detailed description
Referring to the drawings, the embodiment of the invention shown a
T INTEGRATED FORMWORK consists of one or more panels that may have
any shape, plane or curve or any three dimensional shape.
T INTEGRATED FORMWORK may be made of concrete or reinforced
concrete or prestressed concrete or posttensioned concrete or of
any material with suitable properties. The T INTEGRATED FORMWORK
is a thin plate made of reinforced concrete having the dimensions,
width and length, that may be equal to the dimensions of the whole
element such as a wall, a floor slab, a beam, a column, etc., or
may be smaller depending on many factors, conditions, etc. The
thickness may range, but is not limited to, between several
milimeters to several centimetres. A T INTEGRATED FORMWORK may
comprise inserts made of a piece of sheet metal 54 fig. l, 2, 3, 4
and a nut 56 fig. 1, 2, 3 welded together. The piece 54 has a hole
that will preferably be in the middle. The nut 56 will be centred
on this hole. The inserts, 54 and 56, may be placed on a base
surface 51 of a work table 50 fig. 1 in a grid pattern as seen in
fig. 4. The T INTEGRATED FORMWORK comprises also a reinforcement
20 for the concrete that may be a steel welded wire mesh 60 fig. 1.
The inserts 54 and 56 may be secured to the steel mesh 60 in order
to remain as positioned. The threaded rod 58 fig 1, 2, 3, 4, 5 is
screwed into the nut 56 before the concrete 62 fig 1, 6, will be
placed. The threaded rod 58 is not a part of the T INTEGRATED
FORMWORK but it has a temporary purpose: to help attaching steel
28
21209S7
products (like U channel shaped) or wood pieces, etc., to the T
INTEGRATED FORMWORK in order to strengthen it so it would be ready
for manipulations, installation, transportation, etc.
The process for producing a T INTEGRATED FORMWORK exemplified
by a preferred embodiment is described with reference to the
drawings and comprises the following steps:
- preparing a base surface 50 fig 1, 6 having any shape: plane or
curved or any three dimensional shape, according to the shape
of T INTEGRATED FORMWORK. The base may have a mechanism for
vibrating the fresh concrete placed on it. The base surface
may be covered with a layer that will not allow the fresh
concrete to stick to the base surface. For this purpose may
be used a special paint, etc.
- placing shutters 52 fig 4, 5, 6 made of steel products U
channel shaped, wood products 2x4, etc., on the base surface
50 along the perimeter of the T INTEGRATED FORMWORK according
to its shape and its dimensions.
- placing also shutters 90 fig 10 made of steel, wood, etc.,
on the base surface along the perimeter of the opening (doors,
20 windows, ducts).
- placing the reinforcement for the concrete or for another
material used that may be a steel welded wire mesh 60 or
etc.
- placing the insert 54 and 56 and securing them preferably to
the wire mesh 60.
29
21209S7
placing the fresh concrete 62 or other material on the base
surface between shutters and processing it. One face or both
faces of the T INTEGRATED FORMWORK may be unfinished. However
it is possible to finish the top face or the bottom face or
both sides, bottom and top. ~inishing the upper surface of
the concrete may be performed in various ways according to the
design:
- getting a rough surface or a smooth fine surface.
- imprinting a pattern.
_placing ornamental lumber boards in patterns, etc.
_placing tiles or marble, etc., in patterns, etc.
_placing ornamental bricks 118 fig. 20 in order
to get a pattern similar to one used currently
for exterior walls in residential or highrise construction.
Such a T INTEGRATED FORMWORK may be pre-manufactured
completely and installed in the construction. Many
other kinds of finish may be executed on the
T INTEGRATED FORMWORKS top surface 64 fig. 1.
To execute a finish on the bottom surface 66 fig. 1 of the
20 T INTEGRATED FORMWORK the following steps may be necessary:
preparing a base surface 51 having a shape that fits the shape
of T INTEGRATED FORMWORK: plane or curved or any three
dimensional shape.
placing shutters 52 fig 5, 6 made of steel, wood, etc., on
the base surface 51 along the perimeter of the T INTEGRATED
~,~, lj
2120957
FOR~ORK according to its dimensions and shape.
- placing shutters 90 fig. 10 on the base surface along the
perimeter of the openings (doors, windows, etc).
- processing the finish on the bottom side of T INTEGRATED
FORMWORK facing the base surface by:
_ placing ornamental bricks 118 fig. 19 or
_ placing tiles or ornamental stones or marble, or
_ placing ornamental lumber boards in patterns or
other materials on the base surface 51 fig. 19
lo - placing inserts 54 and 56 fig. 1 having threaded rods 58
screwed in.
- placing the reinforcement: steel welded wire mesh 60 fig. 1
or steel bars, etc.
- placing the fresh concrete 62 fig. 1, 19.
- processing the surface of the concrete as designed.
When the concrete has hardened enough the T INTEGRATED
FORMWORK may be used. Generally a T INTEGRATED FORMWORK is very
thin in comparison with its widths and lengths and therefore is
fragile and may need temporary reinforcement. This reinforcement
~ 20 may have multiple purposes: for strengthening, manipulation,
transportation, assembling, installation, connections, support,
etc. First a thin protective layer 65 fig. 1 of cardboard or
plastic sheet, etc., will be placed on the finished surface of
T INTEGRATED FORMWORK, then steel products (U channel shaped)
68 and 70 fig. 1 or wood 2x4, etc., will be placed in a grid
31
21209~7
-
pattern fig. 5 on the T INTEGRATED FORMWORK surface. The U channel
shaped pieces 68, 70 have holes centred on the rods 58. By
tightening the nuts 72 fig. 1 on the washers 74 fig. 1 the steel U
channel 6~ and 70 (in both directions) will be fastened to the T
- INTEGRATED EORMWORKS giving it enough strength to be manipulated
for further operations.
Building an interior or exterior wall
The T INTEGRATED FORMWORK may be put in a vertical position or
in any other convenient position in order to attach to it
lO insulation material 98 fig. 13, 14 and/or reinforcement steel bars
82 fig. 13, 14 or steel welded wire mesh and/or piping 102 fig. 13,
14 and/or cables 106 fig. 13, wires 104 fig. 13 and/or
shutters for openings 90 fig. 10 and/or steel U channel shaped 120
and/or wood 2x4 126. etc. After placing all this materials,
devices, etc., a second T INTEGRATED FORMWORK will be placed at a
certain distance near the first T INTEGRATED ~ORMWORK as seen in
fig. 7, 13, 14. The threaded rods 58 will be removed in both
T INTEGRATED FORMWORKS and longer threaded rods 76 fig. 7 Will be
introduced instead as wall ties. The rods 78 will pass through
~ 2~ both T INTEGRATED FORMWORKS 63 fig. 7 and their steel U channel
shaped 68 and 70 fig. 7. The threaded rod 76 will be placed inside
the plastic pipe 78 fig. 7 so it will not come in contact with the
fresh concrete and so the rod will be removable. The plastic pipe
78 Will act as a spacer maintaining the distance between the two T
INTEGRATED FORMWORKS while they are tightened to each other when
32
2120957
-
the nut 84 fig. 7 is fastened against the washer 86 fig. 7. At the
other end of the rod may be either another nut 84 fig. 7 or a fixed
head 80 fig. 7 and a washer 86 fig. 7. After the two T INTEGRATED
FO~WORKS are fastened they constitute a strong assembly that may
- be transported to be installed in the structure by connecting it to
neighbouring elements. The procedure of assembling the two T
INTEGRATED FORMWORKS may be executed also in the structure bringing
there T INTEGRATED FORMWORKS separately and tightening them
together as explain above. Assembling two T INTEGRATED FORMWOR~S
lo in order to produce a wall or other element may be performed also
by placing steel products U channel shaped 120 fig 22 or wood
products 126 fig 22 2x4, etc., between the two T INTEGRATED
FORMWORKS. By tightening the nuts 84 on the threaded rod 76 fig.
22 the two T INTEGRATED FORMWORKS will be fastened to each other.
Another possibility to produce a wall, etc., is to use
T INTEGRATED FORMWORK having little exterior concrete beams 122
fig. 23 or having little interior concrete beams 124 fig. 24.
These little beams are intended to strengthen the T INTEGRATED
FOR~ORKS. The two T INTEGRATED FORMWORKS will be fastened to each
20 other by tightening the nuts 84 on the threaded rod 76 fig. 23, 24.
After the assembly of the T INTEGRATED FORMWORK is installed and
supported the fresh concrete 88 fig. 7 will be placed inside and
processed. After the concrete has hardened enough according to the
regulations, the rod 76 and the U channel shaped pieces 68 and 70
33
' -7
2120957
and all the supports will be dismantled and removed. The inside of
the plastic pipe 78 may be filled with grout. The two T INTEGRATED
~ORMWORKS 63 fig. 7 will remain integrated permanently in the wall
having the faces already finished so that money and time are saved.
Buildinq a floor slab
While processing the surface of the fresh concrete the T INTEGRATED
FORMWORK may get the upper face finished as a smooth fine surface
similarly to the quality of a dry wall panel. Then this finished
face will be protected with a thin layer of cardboard or paper or
plastic sheet, etc. Then the following steps may be performed:
- placing steel U channel shaped 68 and 70 fig. 5 on the
protective layer and tightening them to the T INTEGRATED
FORMWORKS by using rods 58 fig. 1, nuts 72 and washers 74
fig. 1.
- transporting, installing and supporting the T INTEGRATED
FORMWORK in the structure.
- installing reinforcement 100 fig. 9 for the fresh concrete
that will be placed on the upper side of the T INTEGRATED
FORMWORKS.
- 2O - connecting the steel welded wire mesh 60 fig. 1 with the
reinforcement bars 100 fig. 9 in order to achieve cooperation
between the T INTEGRATED FORMWORK 67 fig. 9 and the concrete
88 fig. 9 in the slab.
- installing cables 106 fig. 9, piping 102 fig. 9, wiring, etc.,
on the upper face of the T INTEGRATED FORMWORK.
34
21209~7
- placing fresh concrete and processing it.
- finishing the upper face of the fresh concrete as designed.
- dismantling the steel U channel shaped 68 and 70 that
supported the T INTEGRATED FORMWORK from below, by removing
the rod 58, etc.
- filling with grout the holes left after removing the rod 58.
Building a column or a beam
According to the conditions the process may comprise the
following steps:
- manufacturing T. INTEGRATED FORMWORKS having the shape fitting
the sections of the column. For instance: for a rectangular
section the T. INTEGRATED FORMWORK may be shaped as follows:
4 T. INTEGRATED FORMWORKS 92 fig. 11, 12 assembled in
a rectangular shape; or
2 L shaped T. INTEGRATED FORMWORKS assembled in a
rectangular shape: or
1 U shaped T. INTEGRATED FORMWORKS assembled together
with one plane shaped T. INTEGRATED FORMWORKS in a
rectangular shape.
There may be other ways, too, for forming the columns or the
beams.
- before assembling the parts all the reinforcing steel bars,
piping, wiring, etc., may be attached to one or more
T. INTEGRATED FORMWORKS or introduced between them.
The T. INTEGRATED FORMWORKS will be assembled by using
2120957
steel products, rods 76 fig 11, 12, etc., to form the column or the
beam that will be installed in the structure and supported in the
final position.
Fresh concrete 88 fig. 11, 12 will be placed inside the hollow
section.
After the concrete has hardened enough all the supports, etc.,
will be dismantled. The T. INTEGRATED FORMWORKS will remain
integrated having all the exterior sides already finished.
Buildinq a high column such as for a bridqe or a hiqhway or TV
antenna
The height of such a structure may range, but is not limited
to, 60-100 m high or more. The structure may have a rectangular or
circular, etc., shaped section with a surface of several meters
square. According to the shape and the dimensions of the structure
the following steps may be necessary:
- manufacturing T. INTEGRATED FORMWORKS having the shape of
the structure: plane, curve, etc., such as in the procedure
explained above for building a wall in any concrete structure.
The height of T. INTEGRATED FORMWORKS may be chosen
2~ conveniently and may be about 100 cm but may be also another
dimension.
- after having the base floor ready the erection of the wall will
begin, see the fig 15, 16.
- the first base row of the T. INTEGRATED FORMWORKS 114 fig 15
will be installed to build the base perimeter of the structure.
36
21209S7
The row comprises the T. INTEGRATED FORMWORKS 112 fig 16
assembled together by using steel U channel shaped in both
directions: horizontal pieces 110 fig 16 and vertical pieces
108 fig 16, or other means. All the pieces are tightened with
rods 76 fig 16, nuts, etc., as seen in fig 7.
- after having the first row of T. INTEGRATED FORMWORK placed and
supported, the reinforcement steel bars 117 fig 16 for the
concrete will be installed in the section. Also inserts,
piping 102 fig 16, cables 106 fig 16, etc., will be introduced.
lo The fresh concrete 88 fig 16 will be placed inside and
processed so it will fill the section until about 15-20 cm
under the top.
- the second row of T. INTEGRATED FORMWORK will be installed over
the first one and the same operations will be performed as in
the first row and so on. The structure will be erected row
- after row until the top. The speed of the erection of the
structure will depend on the strengths of each row that have
to support the weight of all the rows above it. The steel
U channel shaped that strengthen the T. INTEGRATED FORMWORKS
2~ will not be dismantled until the concrete of a row has reached
the necessary strength to support the weight of the structure
above it. The shutters for the openings, the inserts, etc.,
will be placed in the regular way similarly to the highrises.
When finally all the supports, etc., will be dismantled all the
concrete surface will be already finished, saving money and
37
212~957
time.
Buildinq a high (or low) structure such as a silo, chimney,
reservoir, water tower etc.
The height of such a structure may range, but is not limited
- to, between 50-200 m. The diameter of such a structure may range,
but is not limited to, between 10-100 m. The structure may have a
rectangular or circular, etc., section. According to the shape and
dimensions of the structure the following steps may be necessary:
- manufacturing T. INTEGRATED EORMWORK having the shape of the
structure: plane, curve, etc., like in the procedure
explained above for building a wall in any concrete structure.
The height of the T. INTEGRATED FORMWORK may be chosen
conveniently and may be about 100 cm but may also be other
dimensions.
- after having the base floor ready, the erection of the wall
will begin as seen in fig 17, 18.
- the first row of T. INTEGRATED FORMWORK 116 fig 17 will be
installed to build the base perimeter of the structure. The
row comprises the interior 116 fig 18 and the exterior 115
2~ fig 18 T. INTEGRATED FORMWORKS assembled together by using
horizontal U channel shaped 110 fig 18 and vertical steel
U channel 108 tightened with rods 76 fig 18, nuts, washers,
etc., as seen in fig 7.
- After having the first row of T. INTEGRATED FORMWORKS placed
and supported, the reinforcement steel bars 117 fig 18 for
38
~,~
21209S7
the concrete will be installed in the wall from the upper side.
Also piping 102 fig 18, cables 106 fig 18, etc., will be
introduced.
the fresh concrete 88 fig 18 will be placed inside the wall
all along the whole perimeter and processed so that it will
fill the T. INTEGRATED FORMWORK until about 15-20 cm under
the top.
the second row of T. INTEGRATED FORMWORKS will be installed
over the first one and the same operations will be repeated
as in the first row and so on. The structure will be erected
row after row until the top. The speed of the erection of
the structure will depend on the strength of each row that
have to support the weight of all the rows above it. The
steel U channel shaped that strengthens the T. INTEGRATED
FORMWORKS of one row will not be dismantled until the
concrete has reached the necessary strength to support the
weight of the structure above it. In high structures that
have openings, inserts, floors, they will be placed and
executed in the regular way similarly to the highrises. When
finally all the supports, etc., will be dismantled all the
concrete surface will be already finished saving money.

Reusable concrete form
Referring to the drawings the embodiment of the invention
shown REUSABLE CONCREl~E FORI~ consists of one or more panels that
may have any shape, plane or curve or any three dimensional shape.
- REUSABLE CONCRETE FORM may be made of concrete or reinforced
concrete or prestressed concrete or posttensioned concrete or of
any material with suitable properties.
The REUSABLE CONCRETE FORM is a thin plate having the
dimensions, widths and lengths, that may be equal to the dimensions
of the whole element such as wall, a floor slab, a beam, a column,
etc., or may be smaller depending on many factors and conditions,
etc. The thickness may range, but is not limited, between several
millimetres to several centimetres. A REUSABLE CONCRETE FORM may
comprise inserts made of a piece of sheet metal 54 fig 1, 2, 3, 4,
and a nut 56 fig 1, 2, 3 welded together. The piece 54 has a hole
that will be preferably in the middle. The nut 56 will be centred
on this hole. The inserts 54 and 56 may be placed on a base
surface 51 of a work table 50 fig 1 in a grid pattern as seen in
fig 4. The REUSABLE CONCRETE FORM comprises also a reinforcement
2D for the concrete that may be a steel welded wire mesh 60 fig 1.
The inserts 54 and 56 may be secured to the steel welded wire mesh
in order to remain stable as positioned. The threaded row 58 fig
1, 2, 3, 4 is screwed into the nut 56 before the concrete 62 fig 1,
6, will be placed. The threaded rod 58 is not a part of the
REUSABLE CONCRETE FORM but it has a temporary purpose: to help
~ '1
2120957
attaching steel products or wood pieces, etc., to the REUSABLE
CONC~ETE FORM in order to strengthen it so it would be ready for
manipulations, installation, transportation, etc.
The process for producing REUSABLE CONCRETE FORM exemplified
- by a preferred embodiment is described with reference to the
drawings and comprises the following steps;
- preparing a base surface 50 fig 1, 6 having any shape: plane
or curvèd or any three dimensional shape according to the shape
of REUSABLE CONCRETE FORM. The base may have a mechanism for
vibrating the fresh concrete placed on it. The base surface may
be covered with a layer that will not allow the fresh concrete to
stic~ to the base surface. For this purpose may be used a special
paint, etc.
- placing shutters 52 fig 4, 5, 6 made of steel products U
channel shaped, wood products 2x~, etc., on the base surface
50 along the perimeter of the REUSABLE CONCRETE FORM according
to its shape and dimensions.
- placing also shutters 90 fig 10 made of steel, wood, etc., on
the base surface along the perimeter of the opens (doors,
2~ windows, ducts).
- placing the reinforcement for the concrete that may be a steel
welded wire mesh 60 or etc.
- placing the fresh concrete 62 on the base surface between
shutters and processing it. One face or both faces of the
REUSABLE CONCRETE FORM may be unfinished. However it is
41
~i
2120957
-
possible to finish the top face or the bottom face or both
sides, bottom and top. Finishing the upper surface of the
concrete may be performed in various ways accord~ng to the
design:
- Getting a rough surface or a smooth, fine surface
_ Imprinting a pattern
Such a REUSABLE CONCRETE FORM may be pre-manufactured
completely and installed in the construction. To
execute a finish on the bottom surface 6G fig 1 of
the REUS~BLE CONCRETE FORM the following steps may
be necessary:
preparing a base surface 51 having a shape that fits the
shape of REUSABLE CONCRETE FORM: plane or curve or any
three dimensional shape. The base surface may be smooth
or rough or may have a pattern imprinted or sticking out.
placing shutters 52 fig 5, 6 made of steel, wood, etc.,
on the base surface 51 along the perimeter of the REUSABI.E
CONCRETE FORM according to its dimensions and shape. The
base surface will be prepared to have the job of a mold:
the surface may be smooth or rough, may have a pattern
imprinted or sticking out according to design.
placing shutters 90 fig lO on the base surface along the
perimeter of the openings (doors, windows, etc).
placing inserts 54 and 56 fig 1 having threaded rods
58 screwed in.
42
L. ~
212()957
- placing the reinforcement: steel welded wire mesh 60 fig 1
or steel bars, etc.
- placing the fresh concrete 62 fig 1, 19 and processing it.
- when the concrete has hardened enough the REUSABLE CONCRETE
- FO~WORK may be used. Generally a REUSABLE CONCRETE FORM is
very thin in comparison with its widths and lengths and
therefore is fragile and may need temporary reinforcement.
This reinforcement may have multiple purposes: for strengthening,
manipulation, transportation, assembling, installation,
/o connections, support, etc. First a thin protective layer 65
fig 1 of cardboard or plastic sheet, etc., will be placed on the
finished surface of the REUSABLE CONCRETE FORM. Then steel
products such as U channel shape 68 and 70 fig 1 or wood
2x4 will be placed in a grid pattern fig 5 on the REUSABLE
CONCRETE FORM surface. The U channel shaped pieces have holes
centred on the rods 58. By tightening the nuts 72 fig 1 on
the washers 74 fig 1 the steel U channel shaped 68 and 70
(in both directions) will be fastened to the REUSABLE CONCRETE
FORM giving it enough strength to be manipulated for
further operations.
Buildinq an interior or exterior wall
The REUSABLE CONCRETE FORM may be put in a vertical position
or in any other convenient position in order to attach to it
reinforcement steel bars 82 fig 13, 14 or steel welded wire mesh,
piping 102 fig 13, 14, cables 106 fig 13, wires 104 fig 13,
2120957
shutters for openings 90 fig 10, etc. After placing all these
materials, devices, etc., a second REUSABLE CONCRETE FORM will be
placed at a certain distance near the first one as seen in fig 7,
13, 14. The threaded rods 58 will be removed in both REUSABLE
- CONCRETE FORM and longer threaded rods 76 fig 7 will be introduced
instead as wall ties. The rods 78 will pass through both REUSABLE
CONCRETE FORM 63 fig 7 and through their steel U channel shaped 68
and 70 fig 7. The threaded row 76 will be placed inside the
plastic pipe 78 fig 7 so it will not come in contact with the fresh
concrete and so the rod will be removable. The plastic pipe 78
will act as a spacer maintaining the distance between the two
REUSABLE CONCRETE FORMS while they are tightened to each other when
the nut 84 fig 7 is fastened against the washer 86 fig 7. At the
other end of the rod may be either another nut 84 fig 7 or a fixed
head 80 fig 7 and the washer 86 fig 7. After the two REUSABLE
CONCRETE FORMS are fastened they constitute a strong assembly that
may be transported to be installed in the structure by connecting
it to neighbouring elements. The procedure of assembling the two
REUSABLE CONCRETE FORM may be executed also in the structure
20 bringing them there separately and tightening them together as
explained above. Assembling two REUSABLE CONCRETE FORMS in order
to produce a wall or other element may be performed also by
placing steel products 120 fig 22 U channel shaped or wood 2x4 126
fig 22 or etc., between the two REUSABLE CONCRETE FORM. By
tightening the nuts 84 on the threaded rod 76 fig 22 the two
44
ll~
21209S7
REUSABLE CONCRETE FORM will be fastened to each other.
Another possibility to produce a wall, etc., is to use
REUSABLE CONCRETE FORMS having little exterior concrete beams 122
fig 23 or having little interior concrete beams 124 fig 24. This
little beams are intended to strengthen the REUSABLE CONCRETE
FORMS. The two REUSABLE CONCRETE FORMS will be fastened to each
other by tightening the nuts 84 on the threaded rod 76 fig 23, 24.
After the assembly of the REUSABLE CONCRETE FORMS is installed and
supported the fresh concrete 88 fig 7 will be placed inside and
t~ processed. After the concrete has hardened enough according to the
regulations, the rod 76 and the U channel shaped pieces 68 and 70
and all the supports will be dismantled and removed. The inside of
the plastic pipe 78 will be filled with grout. The two REUSABLE
-CONCRETE FORMS 63 fig 7 will be removed and prepared to be reused.
In a similar way, with some variation according to the nature
of the structure, the REUSABLE CONCRETE FORMS may be used in
processes for producing all kinds of structures: floor slabs,
columns, beams, very high columns, silo, chimney, etc. All these
processes are similar to the processes for producing floor slabs,
- 20 columns, beams, very high columns, silos, chimneys, etc., that use
the T. INTEGRATED FORMWORKS. The basic difference is that in the
last stage the Reusable concrete forms are dismantled and removed.
Although a few embodiments of the present invention has been
described and illustrated, the present invention is not limited to
the features of these emodiments but includes all variations and
2120957
modifications within the scope of the claims.
The assembly of two or more T. INTEGRATED FORMWORKS or
REUSABLE CONCRETE FORMS in order to produce a wall or any other
element of a structure may be performed in a convenient place and
then transported to the structure or may be performed in the
structure itself or close to it.
The base surface used to produce a T. INTEGRATED FORMWORK or
a REUSABLE CONCRETE FORM may be the face of a table or may be
prepared on the ground on a concrete slab, etc.
/o The order and the nature of the steps for producing a T.
INTEGRATED FORMWORKS, a REUSABLE CONCRETE FORM or a concrete
element may be changed according to neccessities.
The T. INTEGRATED FORMWORK and REUSABLE CONCRETE FORM may have
standard sizes such as 2'x8', 4'x8', etc., or may have the size of
half or a whole element: wall, floor slab, etc.
In order to get a strong connection between the neighbouring
elements in a structure it is highly recommended that the
reinforcement (steel bars, etc.) from one T. INTEGRATED FORMWORK or
REUSABLE CONCRETE FORM will be long enough to enter ir.to the core
20 of the fresh concrete placed in the neighbouring elements (walls,
floor slab, beams, columns, etc.). Also it is recommended that the
reinforcement (steel bars, etc.) of a T. INTEGRATED FORMWORK or
REUSABLE CONCRETE FORM will be connected to the reinforcement of
the fresh concrete in the same element. This is very important
especially in a floor slab.
46
2120957
