3498541Elongated foldable polygonal casting memberThe disclosed embodiments relate to an elongated foldable polygonal casting member.The disclosed embodiments further relate to an elongated foldable polygonal casting member enabling the elongated foldable polygonal casting member to be folded into a compressed state 5 having a mainly flat shape for transport, and unfolded to form an elongated three-dimensional concrete receiving mold being open in both axial distal ends for receiving concrete to form a concrete structure.Background10 In the construction art, it is common to use elongated mainly tubular casting pipes or similar as casting molds, configured to receive concrete for forming a concrete structure when cured. These cured concrete structures are commonly used to form a support structure for a concrete floor, outdoor porch or patio or the like. The mentioned mainly elongated tubular casting pipes are usually inserted into a hole in the ground, and wherein the soil supports and carries the load of the 15 structure.It is commonly most used rigid elongated tubular tubes or pipes of a prefabricated length and diameter. These can be formed by plastic, cardboard or other suitable materials. The main disadvantages with the prefabricated solutions are that they are space-demanding to store, as well as are space-demanding to transport to remote sites for use, as well as transport to and from stores.20 This also brings along unnecessary costs both for required space for storage and transportation, as well as is not an environmentally friendly solution as this results in unnecessary high CO2 emission. From US6220564 B1 is known a concrete column forming tube stored and displayed for sale in the flat, and under the urging of a pivotal traverse of an internal ring is projected into the much larger three-dimensional shape necessary for forming the concrete column, this reshaping occurring at a 25 site of use having no space limitations.In US2013037979 A1 are described systems and methods for forming concrete footings, wherein the concrete form includes a sleeve with top edge and a bottom portion with a bottom edge generally parallel to the top edge. The bottom portion includes a plurality of bottom severance lines extending from the bottom edge to the top portion, and the top portion includes a plurality of top 30 creases extending from the top edge to the bottom portion. The top creases are generally 3498542perpendicular to the top and bottom edges. The top creases, at least partially, define a plurality of top panels around a periphery of the sleeve, and the bottom severance lines at least partially define a plurality of bottom panels configured to flare out when concrete is poured into the sleeve. The main disadvantages of both US6220564 B1 and US2013037979 A1 are that they are not self-5 supporting and require the use of additional structures to both secure the structure and retain the structure in shape. They further both suffer from small overlap area that requires the use of additional structure elements.Another disadvantage of US6220564 B1 is that the interior circumference of the mold will form a void in the concrete structure.10 Another disadvantage with the prior art solutions is that they are not suitable for being adapted or joined without the use of additional tools or other accessories.A further disadvantage with some prior art solutions is that it is required to process the material with a wax or other chemical treatment, which makes the production complicated and has negative environmental impact.15 The prior art solutions are further not adapted according to standard transport pallets (Euro-pallet) for easy transport and storage.Due to the material used and shape of the prior art solutions they have limited opportunities for production at different locations.Further, as the prior art solutions cannot be completely flat-packed, at least in assembled state, this 20 makes them vulnerable to transport and storage.There is thus a need for an elongated foldable polygonal casting member solving the issues of the prior art solutions.Summary25 The disclosed embodiments provide an elongated foldable polygonal casting member (EFPCM). 3498543Provided herein is an EFPCM being foldable to a transport state, wherein the EFPCM occupies minimum space, and unfoldable to a casting state, wherein the EFPCM forms a polygonal threedimensional concrete receiving mold for receiving concrete to form a concrete structure.Also provided herein is an EFPCM overcoming the foregoing and other shortcomings of the prior art.5 Provided herein is an EFPCM with multiple axially extending folding sections enabling the EFPCM to be folded and flat-packed on a standard transport pallet.Also provided herein is an EFPCM with transversally or circumferentially extending folding sections enabling the EFPCM to be folded and flat-packed on a standard transport pallet.Provided herein is an EFPCM that is manufactured in an environmentally friendly degradable 10 material.Also provided herein is an EFPCM that is adaptable/adjustable on site.Provided herein is an EFPCM that is pre-assembled or can be assembled on site.Also provided herein is an EFPCM that reduces the space/volume required for transport and storage. Provided herein is an EFPCM that is tool free.15 Provided herein is an EFPCM that may be joined to other EFPCMs without the use of tools or requiring additional means.Also provided herein is an EFPCM that is self-supporting.Further features of the present invention will appear from the following description, claims and attached drawings.20The inventionAn elongated foldable polygonal casting member according to the present invention is defined by the technical features of claim 1. Preferable features of the elongated foldable polygonal casting member are described in the dependent claims.25 The inventive embodiments of the present invention are related to an elongated foldable polygonal casting member (EFPCM) being foldable to a transport state and unfoldable and assembled to form 3498544an elongated three-dimensional concrete receiving mold that interiorly is mainly without voids, is self-supported, and is open at axial distal ends for receiving concrete.The EFPCM according to the present invention has a first axial side and a second axial side, as well as a first axial distal end and a second axial distal end.5 The EFPCM according to the present invention is further formed by x axially extending sections, wherein x is an integer number larger than six.The EFPCM is further provided with y axially extending folding sections, extending mainly in parallel between the first and second axial distal ends. In accordance with the EFPCM according to the present invention, the y axially extending folding sections are distributed in circumferential direction 10 thereof and dividing the elongated foldable polygonal casting member into x foldable axially extending sections of approximately the same width.In accordance with the EFPCM according to the present invention, the EFPCM, when unfolded and assembled, form a polygonal three-dimensional concrete receiving mold. The first axially extending section and xth axially extending section overlap forming an interior circumference of the polygonal 15 three-dimensional concrete receiving mold that is mainly without voids and is open at axial distal ends for receiving concrete.According to one embodiment of the EFPCM according to the present invention, at least the first axially extending section or xth axially extending section, or both, at facing surface(s) is/are provided with an adhesive fastening material.20 In accordance with one embodiment of the EFPCM according to the present invention, the EFPCM is pre-assembled by that the first axially extending section and xth axially extending section are attached. In an alternative embodiment of the EFPCM according to the present invention, the EFPCM is configured for post assembly of the first axially extending section and xth axially extending section on site.25 According to one embodiment of the EFPCM according to the present invention, the EFPCM is formed by cardboard or degradable cardboard.In accordance with one embodiment of the EFPCM according to the present invention, the EFPCM is provided with one or more transversally or circumferentially extending perforated ripping sections, enabling the EFPCM to be axially length adjusted. 3498545According to one embodiment of the EFPCM according to the present invention, the adhesive fastening material is pre-applied to the first axially extending section and/or xth axially extending section. In an alternative embodiment of the EFPCM according to the present invention, the adhesive fasting material is configured to be manually applied to the first axially extending section 5 and/or xth axially extending section prior to assembly of the elongated foldable polygonal casting member by means of a manual gluing mechanism.In accordance with one embodiment of the EFPCM according to the present invention, the adhesive fastening material in addition is pre-applied to one or more intermediate axially extending sections. In an alternative embodiment of the EFPCM according to the present invention, the adhesive fasting 10 material is configured to be manually applied to the one or more intermediate axially extending sections prior to assembly of the elongated foldable polygonal casting member by means of a manual gluing mechanism.According to one embodiment of the EFPCM according to the present invention, the adhesive fastening material is glue or a degradable glue.15 In accordance with one embodiment of the EFPCM according to the present invention, the glue or a degradable glue is covered by a removable enclosure.According to one embodiment of the EFPCM according to the present invention, the respective axially extending folding sections in addition are perforated enabling adjustment of the elongated foldable polygonal casting member in circumferential or transversal direction.20 In accordance with one embodiment of the EFPCM according to the present invention, the EFPCM in addition is provided with one or more transversally or circumferentially extending folding sections, enabling the elongated foldable polygonal casting member to also be folded in axial direction.According to one embodiment of the EFPCM according to the present invention, the EFPCM, at the 25 first axial distal end and/or second axial distal end, or both, is provided with axially protruding joining members, configured for enabling joining of at least two EFPCMs in series in axial direction.In accordance with one embodiment of the EFPCM according to the present invention, the axially extending sections are provided with an axially protruding joining member.According to one embodiment of the EFPCM according to the present invention, the axially 30 protruding joining member of alternating axially extending sections, seen in circumferential or 3498546transversal direction of the EFPCM, have a respective first and second axial length. At joining of two EFPCMs axially in series, the axially protruding joining members of opposite first and second axial lengths are accommodated one within the other and joining the two EFPCMs together.In accordance with one embodiment of the EFPCM according to the present invention, the axially 5 extending folding sections, in transversal direction of the EFPCM, are successively wider in the circumferential or transversal direction of overlapping axially extending sections of the EFPCM, from the first axial side of the EFPCM towards the second axial side of the EFPCM, enabling the EFPCM to be assembled in several layers for increased rigidity and structural stiffness.According to one embodiment of the EFPCM according to the present invention, the EFPCM in 10 folded state is configured to be stacked on a standard transport pallet (Euro-pallet).The EFPCM according to the present invention has considerable environmental benefits over the most commonly used prior art solutions.Today 55 pieces of the 20x120 cm prior art casting pipe are shipped on one individual singular standard transport pallet (Euro-pallet), wherein the casting pipes are packed at a height of 2.3 15 meters. By means of the EFPCM according to the present invention one can ship 500 on a singular standard transport pallet (Euro-pallet - a pallet that can be re-used) at a height of only 1 meter. For a volume of 200.000 EFPCMs according to the present invention one will reduce the number of transport pallets required from 3660 to 400 and save large amounts of CO2 emissions on transportation alone.20 Reducing the number of transport pallets significantly further results in lower transport requirements. Assuming that each transport pallet represents a certain travel distance (e.g., km per transport pallet), one with the EFPCM according to the present invention will reduce the total km travelled by 90%, which translates into a proportional reduction in fuel consumption and CO2 emissions.25 By means of the EFPCM according to the present invention enabled is the use of thinner carboard, compared to prior art solutions. By the EFPCM according to the present invention one can reduce the amount of material by over 50%.By reducing the material use by over 50% for the cardboard, the production footprint is halved, reducing energy consumption and waste from materials. Additionally, thinner materials would likely 30 reduce the weight of shipments, leading to further CO2 savings. 3498547A further advantage with the EFPCM according to the present invention is that the simplicity of the production will enable the EFPCM to be produced on multiple production facilities and reduce the need for long-distance transportation.An advantage with the EFPCM according to the present invention is that the EFPCM is 100% 5 degradable.A further advantage with the present invention is that the EFPCM can be completely flat-packed reducing the need for storage space in warehouses and during customer transport. Flat packing increases the number of units that can be stored per cubic meter, reducing the storage footprint in warehouses and transportation trucks, leading to lower operational costs and reduced CO2 10 emissions from logistics. Further, the flat-packed EFPCMs reduce the damage that can occur during transportation and storage.The EFPCM according to the present invention further has considerable production benefits. With the EFPCM according to the present invention one can wary the width of the folding lines to accommodate the way the EFPCM is stored on the transport pallet. It will also increase the durability 15 of the construction by not having bigger folds than necessary (which could impair the construction).By adding perforated ripping sections in various heights of the EFPCM according to the present invention one can make the EFPCM a “tool free” product, as there is no need for knives, scissor or similar to cut the EFPCM into desired lengths.A further advantage of the EFPCM according to the present invention is that the production method 20 and the material used will allow the design of a user’s manual directly on the product, no need for extra packaging or other information leaflets.A further advantage with the EFPCM according to the present invention is that one can implement visual measurements with both cm/inches, on the EFPCM to indicate length and volume needed to fill with concrete.25 The EFPCM according to the present invention is further a one element product and due to the adaptability/adjustment features, different shapes and dimensions can be achieved from the same product. 3498548Due to the EFPCM according to the present invention can be provided with additional transversally or circumferentially folding sections adding foldability, the EFPCM can have extra length and still be able to be flat-packed on a standard transport pallet.Even though degradable cardboard may be the preferred material, the EFPCM may be produced by 5 different materials depending on the size and the construction.The EFPCM according to the present invention, in addition to the above, provides optimized palletization due to the flat-packed design not only reduces volume, but also provides stable and secure stacking, minimizing the risk of damage during transport.Moreover, the EFPCM according to the present invention results in lower customs costs due to 10 reduced unit volume will lead to lower shipping and customs fees, especially for international transport.Further, the EFPCM according to the present invention will result in reduced storage costs due to the flat-packed design allowing more units to be stored in the same warehouse space, lowering storage expenses.15 A further advantage with the EFPCM according to the present invention is that it will not be subjected to deformation during transport and storage. It is well known that prior art solutions, which are not flat-packed during transport and storage, when exposed to moisture, become some deformed. The present invention does not suffer from being deformed even if it is exposed to moisture due to it will be transported and stored in a flat-packed position.20 Further preferable features and advantageous details of the present invention will appear from the following example description, claims and attached drawings.ExampleThe present invention will below be described in further detail with references to the attached 25 drawings, where:Fig.1a-d are principle drawings of an elongated foldable polygonal casting member according to a first embodiment of the present invention, 3498549Fig.2a-d are principle drawings of a second embodiment of an elongated foldable polygonal casting member according to a second embodiment of the present invention,Fig.3a-b are principle drawings of a further embodiment of an elongated foldable polygonal casting member according to the present invention,5 Fig.4a-b are principle drawings of further embodiments of an elongated foldable polygonal casting member according to the present invention, andFig.5 is a principle drawing of a further embodiment of an elongated foldable polygonal casting member according to the present invention.10 The present invention is related to an elongated foldable polygonal casting member (EFPCM) 100 enabling casting of concrete structures.Reference is now made to Fig.1a-d showing principle drawings of a first embodiment of an EFPCM 100 according to the present invention. The EFPCM 100 according to the present invention has a first axial side 101 and a second axial side 102, as well as a first axial distal end 103 and a second 15 axial distal end 104.The EFPCM 100 according to the present invention is formed by x axially extending sections 110a-x, wherein x is an integer number larger than six. In accordance with the present invention, the EFPCM 100 is further provided with y axially extending folding sections 120a-y, wherein y = x-1. The mentioned axially extending folding sections 120a-y are extending mainly in parallel between the 20 first 103 and second 104 axial distal ends. According to the present invention, the y axially extending folding sections 120a-y are distributed in circumferential or transversal direction of the EFPCM 100 and dividing the EFPCM 100 into x foldable axially extending sections 110a-x of approximately the same width.In the EFPCM 100 according to the present invention, when unfolded and assembled to form a 25 polygonal concrete receiving mold, the first axially extending section 110a and xth axially extending section 110x overlap to form an interior circumference mainly without voids, which mold further is self-supported.In accordance with one embodiment of the EFPCM 100 according to the present invention, at least the first axially extending section 110a or xth axially extending section 110x, or both, at facing 34985410surface(s) is/are provided with an adhesive fastening material 130. In accordance with the EFPCM 100 according to the present invention, the adhesive fastening material 130 is applied in axial direction of the first axially extending section 110a or xth axially extending section 110x, or both, and has properties to ensure that the first axially extending section 110a and xth axially extending section 5 110x are retained securely to each other. In addition to the properties of the adhesive fastening material 130 being of importance, the adhesive fastening material 130 has to be applied over a sufficient area of the first axially extending section 110a or xth axially extending section 110x and with a sufficient amount to ensure the required retention effect is achieved.In the embodiment of Fig.1a-d, the EFPCM 100 is formed by seven axially extending sections 110a-10 g and six axially extending folding sections 120a-f that when unfolded and assembled to form the polygonal concrete receiving mold, forming an elongated hexagonal three-dimensional concrete receiving mold being open in both axial distal ends. In folded state the EFPCM 100 is flat-packed as shown in Fig.1d.In Fig.2a-d is shown a second embodiment of the EFPCM 100 according to the present invention, 15 wherein the EFPCM 100 is formed by eleven axially extending sections 110a-k and ten axially extending folding sections 120a-j that when unfolded and assembled to form the polygonal concrete receiving mold, forming an elongated decagonal three-dimensional concrete receiving mold being open in both axial distal ends. In folded state the EFPCM 100 is flat-packed as shown in Fig.2d. In Fig.1c is shown a state where the first embodiment of the EFPCM 100 is partly flat-packed and in 20 Fig.1d the EFPCM 100 is shown in a state where it is fully flat-packed by folding along the axially extending folding sections 120c and 120f. In contrast to many prior art solutions that cannot be folded beyond this partly flat-packed state, the present invention allows the EFPCM 100 to be completely flat-packed.In Fig.2c is shown a state of the second embodiment of the EFPCM 100 where it is partly flat-packed 25 and in Fig.2d the EFPCM 100 is shown in a state where it is fully flat-packed by folding along the axially extending folding sections 120e and 120j. In contrast to many prior art solutions that cannot be folded beyond this partly flat-packed state, the present invention allows the EFPCM 100 to be completely flat-packed.In the fully flat-packed/folded state, the EFPCM 100 in the shown embodiments has a mainly 30 rectangular shape and is configured/designed for being stacked on a standard transport pallet, such as a Euro-pallet, in an optimized manner. 34985411In accordance with one embodiment of the present invention, the EFPCM 100 is pre-assembled by that the first axially extending section 110a and xth axially extending section 110x are attached by means of the adhesive fastening material 130. In the embodiments of Fig.1a-d this means that the first axially extending section 110a and the 7th axially extending section 110g are attached to each 5 other by means of the adhesive fastening material 130, while in Fig, 2a-d the first axially extending section 110a and the 11th axially extending section 110k are attached to each other by means of the adhesive fastening material 130. As shown in Fig.1d and 2d, the EFPCM 100 can still be folded to a flat-packed state.According to one embodiment of the EFPCM 100 according to the present invention, the first axially 10 extending section 110a and xth axially extending section 110x are configured for post assembly by means of the adhesive fastening material 130, i.e. attached to each other during the assembly phase at a construction site.In accordance with one embodiment of the present invention, the adhesive fastening material 130 is pre-applied to the first axially extending section 110a and/or xth axially extending section 110x, or 15 both. In embodiments where the EFPCM 100 is not pre-assembled, the adhesive fasting material 130 is configured to be manually applied to the first axially extending section 110a or xth axially extending section 110x, or both, prior to assembly of the EFPCM 100 by means of a manual gluing mechanism. In an alternative embodiment, the adhesive fastening material 130 is covered by a removable enclosure such as tape, film, foil or similar that after removal exposes the adhesive 20 fastening material 130 and enabling the axially extending section 110a and 110x to be attached.In accordance with one embodiment of the EFPCM 100 according to the present invention, the adhesive fastening material 130 is glue or a degradable glue.In accordance with one embodiment of the present invention, the EFPCM 100 is formed/manufactured by cardboard or degradable cardboard. An advantage with using carboard or 25 degradable cardboard is that this is a material that can easily be adapted/adjusted on site by means of a knife or other suitable material. According to alternative embodiments of the EFPCM 100 according to the present invention, the EFPCM 100 is formed/manufactured by degradable composite, plastics or other degradable material.Reference is now made to 3a-b showing a further embodiment of the EFPCM 100 according to the 30 present invention, wherein the EFPCM 100 is configured to be adapted at site, both in shape and in the number of axially extending sections 110a-o. In the shown embodiment, the adjustable EFPCM 100 is formed by fifteen axially extending sections 110a-o and fourteen axially extending folding 34985412sections 120a-n. In adjustable embodiments, it will be preferable that the adhesive fastening material 130 is pre-applied to a number of axially extending sections 110a-o. In the shown embodiment, the adhesive fasting material 130 is pre-applied to the axially extending sections 110g, 110k and 110o as an example, enabling the adjustable EFPCM 100 to adjusted according to the prior 5 described embodiments in shape and size. However, the adhesive fastening material 130 may be arranged to any other of the intermediate axially extending sections 110b-x, enabling the adjustable EFPCM 100 to form any desired cross-sectional shape and interior circumference. In an alternative embodiment, one applies the adhesive fastening material 130 to the axially extending section in question at the time of assembly, as mentioned above by means of, e.g., a gluing mechanism. 10 If all the axially extending sections 110a-o in this embodiment are used, a tetradecagon (fourteensided polygon) three-dimensional concrete receiving mold is formed.It should be noted that the more axially extending sections 110a-x the EFPCM 100 comprises, the more circular cross-sections for the three-dimensional shape are available. As concrete cures from the outside and inwards, the use of a three-dimensional circular shape will contribute to improved 15 curing of the concrete structure to be formed.However, due to the multiple axially extending folding sections 120a-y, more or less any crosssectional shape can be achieved, such as any polygonal, quadratic, elliptic, rectangular, etc. This makes the present invention usable also for other areas of use. E.g. one can use EFPCM 100 of different shapes and cross-sections arranged inside each other and where concrete is supplied to 20 the spacing between the two EFPCMs 100. Accordingly, the present invention may also be used for forming figurative concrete structures by arranging two or more EFPCMs 100 inside each other or using a EFPCM 100 of a desired shape. E.g. the adjustable EFPCM 100 may be shaped to a desired shape inside or outside another EFPCM 100. Accordingly, the present invention has many different use areas as will be acknowledged by a skilled person.25 In accordance with a further embodiment of the EFPCM 100 according to the present invention, the respective axially extending folding sections 120a-n, or chosen axially extending folding sections 120a-n, are in addition perforated enabling adjustment of the EFPCM 100 in circumferential or transversal direction. Accordingly, by this embodiment, the EFPCM 100 can be adjusted without the use of any tools.30 Reference is now made to Fig.4a-b showing further embodiments of the EFPCM 100 according to the present invention. 34985413In accordance with one embodiment of the EFPCM 100 according to the present invention, the EFPCM 100 is further provided with one or more transversally or circumferentially extending perforated ripping sections 140, i.e. extending in transversal direction of the axially extending sections 110a-x, enabling the EFPCM 100 to be axially length adjusted on site without the use of any 5 tools.In an alternative embodiment, the EFPCM 100 is length adjusted by using a proper cutting tool, such as a knife, scissors or similar, to cut the EFPCM 100 in appropriate length by performing a cutting in transversal or circumferential direction thereof.Accordingly, by means of a proper cutting tool and/or the mentioned perforated axially extending 10 folding sections 120a-y and/or the one or more transversally or circumferentially extending perforated ripping sections 140, the EFPCM 100 can be adjusted both in length and in number of axially extending sections 110a-x.By adding this feature to the features described above, this results in that shapes with different heights can be formed, such as a stepped structure.15 In accordance with a further embodiment of the EFPCM 100 according to the present invention, the axially extending folding sections 120a-y in transversal direction, for overlapping axially extending sections 110a-x, are successively wider or provided with increased flexibility in the circumferential or transversal direction of the EFPCM 100, from the first axial side 101 of the EFPCM 100 towards the second axial side 102 of the EFPCM 100, enabling the EFPCM 100 to be assembled in several 20 layers for increased rigidity and structural stiffness. Accordingly, by assembling the EFPCM 100 by arranging the axially extending sections 110a-x in several layers, the flexibility or increasing width of the axially extending folding sections 120a-y ensures that the overlapping axially extending sections 110a-x align.In an alternative embodiment, the same effect is achieved by the axially extending sections 110a-x 25 to be overlapping being provided with a successively larger width to compensate for the larger circumference occurring for the additional layer of axially extending sections 110a-x.Reference is now made to Fig.5 showing a further embodiment of the EFPCM 100 according to the present invention, wherein the EFPCM 100 in addition is provided with one or more transversally or circumferentially extending folding sections 150, enabling the EFPCM 100 to also be folded in axial 30 direction.
