[0106] FIG. 1 shows a schematic horizontal cross sectional view of a construction 10 according to an embodiment of the present invention. The construction 10 may particularly be a wall or pillar or any other type of architectural structure.

[0107] The construction 10 comprises a supporting portion 12 and a covering portion 14 for covering the supporting portion 12. The supporting portion 12 may be provided by solid material pieces 16 and at least one string 18 for jamming at least some of the solid material pieces 16. The covering portion 14 comprises at least one covering device 20, preferably a plurality of covering devices 20. The string 18 and the covering devices 20 are attached to each other, which is described in more detail below.

[0108] The covering portion 14 is arranged around the supporting portion 12 on a plurality of sides of the supporting portion 12. In particular, the covering portion is arranged around the supporting portion 12 on vertically extending sides. The covering portion 14 may provide a cast for the supporting portion 12, particularly a cast for a compound of the solid material pieces 16 and the string 18 of the supporting portion 12.

[0109] It may be comprehended from FIG. 1 that the covering devices 20 are larger than the solid material pieces 16, and may also be made from a different material and/or have a different optical appearance than at least some of the solid material pieces 16 of the supporting structure 12. The solid material pieces 16 may particularly be provided as crushed rocks, angular rocks, granular stone material and/or broken stones. It is also possible that the solid material pieces 16 are made from and/or contain glass material and/or glass gravel and/or glass chippings. The solid material pieces 16 may be jammed and/or stamped and/or compressed, preferably for increasing a jamming effect.

[0110] As may further be comprehended from FIG. 1, the string 18 may be at least section wise laid within and/or throughout the supporting portion 12 and/or between the solid material pieces 16 and/or loosely laid and/or at least section wise tightened, preferably for increasing a jamming effect. The string 18 may be arranged in a pattern alternatingly running between a central area 22 of the supporting portion 12 and different covering devices 20.

[0111] The solid material pieces 16 of the supporting portion 12 may be compressed and/or stamped against the covering portion 14 and/or against the covering devices 20 and/or while being held and/or limited by the covering devices 20. At the same time, the covering portion 14 may allow shifting and/or movements of the solid material pieces 16. Furthermore, the covering portion 14 and/or the covering devices 20 may be fixed and/or held by the supporting portion 12, preferably by the compressed and/or stamped and/or jammed solid material pieces 16 and/or by the string 18, particularly by a compound made of the solid material pieces 16 and the string 18.

[0112] The covering devices 20 may be made of and/or comprise a stone and/or glass and/or metal material. As may be comprehended in more detail from FIG. 2, the at least one covering device 20 may comprise a visible side 24 facing away from the supporting portion 12 and furthermore a functional side 26 facing the supporting portion 12. The string 18 is attached to the covering device 20 at the functional side 26.

[0113] The attachment between the string 18 and the at least one covering device 20 may be provided via a form fit and/or non-positive connection and/or via an adhesive. In the example of FIG. 2, the covering device 20 comprises at least one outer component 28 and an attachment element 30 for the attachment with the string 18. The attachment element 30 may be provided on the functional side 26, whereas the visible side 24 faces away from the attachment element 30. The attachment element 30 may be configured as a hook and/or eye and/or notch, to which the string 18 is attached and/or hooked.

[0114] As indicated in FIG. 2, the outer element 28 is arranged substantially on the same level as the attachment element 30. But is also possible that the outer element 28 is arranged below the attachment element 30 or the attachment level is arranged at least slightly or section wise above the outer element 28. Such arrangement may facilitate the dewatering of the construction. The covering devices 20 may accordingly be arranged on top of each other in the manner of scales. The construction may thus provide a bucket for plants in a preferred embodiment.

[0115] In the embodiments of FIGS. 3 and 4, at least one of the covering devices 20 comprises two or three outer components 28 being attached together via an interconnection 32. The interconnection may preferably provide an attachment element 30, to which the string 18 is attached and/or hooked. Accordingly, a covering device 20 may comprise several outer components 28, an interconnection 32 between the outer components 28 and an attachment element 30. Such covering device 20 may particularly be arranged in an edge position or form an edge or corner of the construction.

[0116] In case a covering device 20 for a corner or an edge comprises several outer components 28, the latter may be reduced in weight and/or size, for example, by cutting and/or by more than 20%, more than 30%, more than 40%, more than 50%, more than 60%, or more than 70% of their weight or size. In this way, such a covering device 20 with several outer components 28 may have the same weight as a covering device 20 with only one outer component 28.

[0117] As may furthermore be comprehended from FIG. 2, the at least one covering device 20 may comprise an identification device 34, preferably arranged on an attachment element 30. The identification device 34 may be preferably configured as flat platform and/or for detection by a sensor or visible for a human and/or configured with a position and/or orientation marker and/or a data code or device ID.

[0118] Furthermore, the at least one covering device 20 may comprise a shielding element 36 arranged on a functional side 26 facing the supporting portion 12. The shielding element 36 may be configured for maintaining a distance between the solid material pieces 16 of the supporting portion 12 and an outer component 28 of the covering device 20. The shielding element 36 may be arranged and/or fixed on the attachment element 30 of the covering device 20.

[0119] At least one illuminant 38, preferably a plurality of illuminants 38 and/or a light chain, may be arranged in a free space between the supporting portion 12 and a visible side 24 of the covering portion 14 , preferably in a free space between the shielding element 36 and the outer component 28 of the covering device 20. Two adjacent covering devices 20 may be arranged at a distance from each other and/or a gap may be provided between two adjacent covering devices, such that light from the illuminant 38 may shine through said gaps.

[0120] Now referring to the embodiment in FIG. 5, the covering portion 14 may furthermore comprises a metal flange 40, preferably a metal flange 40 mounted to the supporting portion 12 and/or mounted to the supporting portion 12 subsequent to the building of the supporting portion 12. The metal flange may be mounted by at least one hook 42 being inserted into the supporting portion 12.

[0121] It may furthermore be comprehended from FIG. 5 that the construction 10 may comprise a sink 44. Solid material pieces 16 breaking and/or detaching from the supporting structure may fall through gaps between two adjacent covering devices 20 and into said sink 44. The solid material pieces 16 may remain in the sink 44 for decorative purposes.

[0122] According to the embodiment in FIG. 6, the covering portion 14 may comprise a top cover portion 46 covering at least the supporting portion 12 from an upper side and/or being positioned on top of a vertically extending side cover portion 48 of the covering portion 14. The top cover portion 46 may be a 3D printed structure and/or printed as a negative form of the upper surface of the supporting structure 12 and/or the upper surface of the side cover portion 48. The top cover portion 46 may be configured as a flat platform, preferably for installation of a roof and/or a light source 50. The top cover portion 46 may be transparent, translucent and/or from a glass material and/or from frosted glass material.

[0123] As may be seen from FIG. 6, the light source 50 is installed on top of the top cover portion 46 in order to illuminate the supporting portion 12. The light path 52 may pass from the light source 50 into the supporting portion and out of the construction 10 via the covering portion 14, particularly via a side cover portion 48.

[0124] A mirror 54 may be installed on top of the supporting portion 12 and/or on top of the top cover portion 46 and/or on top of a light source 50, preferably for reflecting light into the supporting portion 12. The mirror 54 may have overhanging portions 56, preferably for reflecting light into the supporting portion 12 along an inner optical path 52 and/or for reflecting light onto the covering portion 14 from the outside, particularly along a light path 58 extending at least section wise outside the covering portion 14.

[0125] FIG. 7 shows a schematic flow diagram of a method according to an embodiment of the present invention. In a first step 100, according to FIG. 7, a model of the construction may be sliced into horizontal layers, for example of 10 mm height or thickness. If a layer of the construction 10 is larger than the range of the human arm or possible robotic kinematics, it may also be sliced vertically into segments. A layer segment marks an intended layer area which shall be built, as shown in FIGS. 1, 3 and 4. The intended layer may be mapped to the real topology of the respective land or soil or ground.

[0126] According to step 200 in FIG. 7, the topology inside the intended layer area, that is, the area for the supporting portion 12, may be scanned. The topology may be appropriate, if the outer area of the intended layout area, that is, the area for the covering portion 14, is higher everywhere than the inner area. Thus, the inner area is having a cast surrounding. If this is not the case, the sections with lower outer area are identified and covering devices 20, such as large surface stones, for example, with a weight of 1.5 kg to 1.8 kg, may be are loosely laid out in these sections according to step 300. In a preferred solution, the covering device 20 may be designed in accordance with FIG. 2.

[0127] In step 400 shown in the diagram of FIG. 7, a string 18 may be laid out. The laying pattern for the string 18 can be random. The process step 400 may be finished, when all covering devices 20 are connected to a string 18 of that layer. To connect a string 18 to covering devices 20, the string 18 may be first being laid out to the centre region 22 of the intended area. Then, it is moved indirectly with some random patterns towards covering device 20. The string is then connected to the covering device 20.

[0128] In a preferred solution, the respective string 18 may be hooked into the attachment element 30 shown in FIG. 2, and then laid back randomly to the centre region 22.

[0129] This is repeated with the next covering device 20. In a preferred solution, it may be any other covering device 20, but not a covering device 20 directly adjacent to one that has been connected before. After all covering devices 20 are connected to the string 18, the string 18 is laid to the centre region 22. Preferably, the string 18 is not cut off, but held in a waiting position above the intended layer.

[0130] According to step 500, a layer of solid material pieces 16 is being placed above the string 18. In a preferred solution, stones with edges and size of 6 mm to 12 mm are filled in, until about 50% to 90%, preferably 80%, of the string 18 becomes hidden. Preferably, solid material pieces 16 are placed behind every covering device 20, without pushing the string 18 straight downwards. Instead, the string 18 shall continue to be directed towards the centre region 22.

[0131] According to step 600, the compound of string 18 and solid material pieces 16 is stamped to reduce its packaging size and for the string 18 to be held tight by the solid material pieces. This stamping also increases the jamming effect. A hitting surface of an appropriate stamping tool may preferably be flat and the stamping force may be applied to the entire area to be stamped at the same time.

[0132] The applied stamping force might have displaced some of the covering devices 20. According to step 700, such covering devices 20 may be repositioned by pushing them back to the assigned position.

[0133] In step 800 it is checked whether or not the last layer has been generated, and if not, the procedure is being repeated for the next intended layer. In case the last layer has been generated the process is terminated in step 900.

[0134] In a preferred embodiment, step 400 is being extended by more sub-steps. Before the string 18 is laid out, a chain of lights may be laid out along the functional side 26 of the covering devices 20, see FIG. 2. Another sub-step could be that different strings 18 are applied at different locations of an area. If an area is exposed to heat of fire, the respective string 18 needs to be designed as iron wire or other resistant material. If the user wishes a segment of the construction 10 to decompose naturally, a decomposable rope should be applied as string 18. If a lasting construction 10 is requested by a user a recycled rope of long-lasting material should be applied as string 18. Also a string 18 made of carbon fibre and recycled rope would be possible. Natural rope would be useful as string 18, if an ecological construction 10 is intended which attracts a diversity of animals and/or plants.

[0135] In a preferred solution, the covering devices 20 are sorted according to different parameters, such as the form. The form of neighbouring covering devices 20 may match in order to minimize the gap in between. However, gaps can also be applied as a design feature. For example, if illuminated, gaps can become a main design element. To control the form of the gap, it may be necessary to choose the right covering devices 20 from a pool of sorted and/or digitalized covering devices 20. As the covering devices 20 may create a grid of gaps, almost every shape could be illuminated if the right lights would be activated.

[0136] It would be a favourable to apply covering devices 20 with a certain degree of transparency or translucence, so they can become illuminated. In that case, the covering devices would need to be sorted according to their transparency or translucence and shining effects. The centre of mass of a covering device 20 may be another sorting criteria. As the covering devices 20 are laid out loosely on top of covering devices 20, there is a risk of dropping off. Spherical stones may have the highest probability to drop, whereas flat stones have a lower probability and long and flat stones have a much lower probability to drop. So, if it is intended to build a wall structure with overhanging wall segments then long and flat stones should be chosen for these segments. Thus, each layer would be slightly overhanging towards the layer below and the surface stones could still be laid loosely, before connected to the string 18.

[0137] The jamming effect may stabilize against induced pressure from top, but not so much from force applied from sides. To secure the construction 10 against forces induced from a side it may be possible to integrate rigid and/or fixed elements—not shown here—to the construction 10. These could be already existing elements from an old wall or fence or it could be a pile or post which is tied to and/or embedded in the ground or soil. In a preferred solution, such rigid and/or fixed elements may be equipped with connection areas for the string 18, for example hooks. The rigid and/or fixed element may then be enclosed by the supporting portion 12 during the build process. The string 18 may be laid around the rigid or fixed element from all sides is connected to the rigid or fixed element and therefore fixed. To make sure, that the jamming effect of the compound is not being impaired by rigid or fixed elements, the elements should be enclosed everywhere by the compound of the supporting portion 12 with a thickness of at least ten solid material pieces or stones of the compound.

[0138] In a preferred solution, a segment of the construction can be used as a fireplace. A typical disadvantage of fireplaces is that solid burning material is laid out mainly horizontally. But the users are sitting aside of the fireplace and therefore the largest surface of the burning material not being presented to the user. While this might be of minor importance during a burning phase with high flames, it becomes relevant in the long lasting glowing phase of the burning material. To present the glowing material vertically to the user and to send out most of the heat radiation directly to the user, it is required to fix the burning material vertically. To achieve that, the compound material of the supporting portion may be provided not from stones but from charcoal and iron wire as a string. Through this, charcoal pieces can be fixed vertically. In a preferred solution, an iron frame which may comprise a door and a heat resistant window may be mounted in front of the charcoal. The glass may have a distance of 20 mm to the charcoal. Through this, smoke may leave the space between coal and glass by the chimney effect to above and the glass becomes hot enough for smoke residues to dissolve and vanish.

[0139] FIG. 8 shows a schematic sectional view of a covering device 20 according to an embodiment of the present invention. The covering device 20 shown in FIG. 8 comprises an outer component 28 and an attachment element 60 and for the attachment with the string 18. The attachment element 60 is configured as and/or comprises a screw 62, wherein the screw is preferably configured as a concrete screw. The screw 62 may be screwed into the outer component 28, preferably free of any dowel or screw anchor.

[0140] The screw 62 may comprise a shaft 64 and a screw head 66 attached to the shaft 64. The shaft 64 may comprise a protrusion 68, particularly a radial protrusion, being arranged at a distance from the screw head 66 in a longitudinal direction of the shaft 64, wherein the shaft 64 and/or the protrusion 68 and/or the screw head 66 may provide a gripping portion for a robot and/or gripping device.

[0141] The screw head 66 may be provided with insertion chamfers 70 and/or the protrusion 68 may be provided with insertion chamfers 70, wherein insertion chamfers 70 and 72 face each other in the longitudinal direction of the shaft 64. The insertion chamfers 70 and 72 may be provided for accurate and/or facilitated gripping and alignment of the covering device 20 by a robot or gripping device.

[0142] Furthermore, the attachment element 60 may comprise a disc 74 for engagement by the string 18. FIG. 9 shows a schematic perspective view of the disc 74.

[0143] As shown in FIGS. 8 and 9, the disc 74 comprises a plurality of teeth 76 arranged on the outer circumference of the disc 74, wherein the teeth 76 are configured for engagement and/or locking and/or trapping engagement with the string 18. Recesses 77 are provided between two adjacent teeth 76. In case of engagement of the string 18 with a tooth, the string may be arranged within one of the recesses 77.

[0144] The disc 74 may be arranged on the shaft 64 of a screw 62, preferably at distance from the outer component 28 and/or between the outer component 28 and the screw head 66 and/or between the outer component 28 and the protrusion 68. The string 18 may thus slide into a gap between the outer component 28 and the disc 74, and when pulled due to a jamming or compressing procedure, may be engaged with teeth 76 of the disc 74 with sufficiently high probability.

[0145] FIG. 10 shows a schematic vertical cross sectional view of a construction 10 according to a further embodiment of the present invention from the side. According to FIG. 10, the supporting portion 12 and the covering portion 14 enclose a fence 78, preferable a fence 78 comprising a double rod mat 80 attached by clamping elements to a solid pile (not shown here in detail) arranged within the respective soil or ground. Horizontally extending supporting elements 82 are attached to the double rod mat 80. The supporting elements 82 may be configured for supporting solid material pieces 16 of the supporting portion 12 and transferring their weight load to the double rod mat 80 of the fence 78.

[0146] The horizontally extending supporting elements 82 may be provided by a weather-proof upper portion and a dissolving or degradable lower portion, the dissolving or degradable lower portion being configured for the development of cavities below the supporting elements 82 for improved weight load transferral to the double rod mat 80.

[0147] The double rod mat 80 of the fence 78 may be attached to the top cover portion 46 for transferring a weight load via the top cover portion 46 to the covering portion 14, in particular to vertical sides of the cover portion 14.

[0148] For building a construction 10 according to the embodiment in FIG. 10, the clamping elements of the fence 78 are release and the double rod mat 80 of the fence 78 is being moved several centimetres higher, for example 5 cm.

[0149] To hold the double rod mat 80 in the new position, an additional, non-permanent device (not shown here) may be applied to lock the double rod mat 80 in its elevated position. Such device can be any device which is suitable to unlock, after the construction is finalized, such as a cardboard base below the fence 78 or double rod mat 80, which dissolves when watered.

[0150] The clamping elements of the fence 78 remain loose to not enable linear motion of the double rod mat 80 in the vertical direction, but still locking it to the respective pile in the horizontal directions. Horizontal supporting elements 82 are now being attached to the fence double rod mat 80. When the construction 10 is being built, a considerable part of the weight of the supporting portion 12, respectively the solid material pieces 16, is loaded on the horizontal supporting elements 82.

[0151] As mentioned above, the horizontally extending supporting elements 82 consist of a solid part on the upper side and a non-permanent part on the lower side. The non-permanent part may dissolve after the construction is finished. They may also consist of cardboard or other material, which dissolves entirely when watered. The function of the non-permanent material is to prevent the solid material pieces 16 to allocate the space on the lower side of horizontal supporting elements 82.

[0152] The function of the horizontal supporting elements 82 is to carry the weight load of the supporting portion 12 as soon as all non-permanent elements dissolve, or at least a high portion of that load, e.g. 50% or 70% or 80%. The force of that static load is then passed to the double rod mat 80. The double rod mat 80 is permanently attached to the top cover portion 46. Consequently, top cover portion 46 is loaded with the weight and passes that weight directly to the outer covering portion 14, that is, the side part of the covering portion 14.

[0153] The covering devices 20 are thus being loaded at least with part of the weight of the supporting portion 12. Therefore, the covering devices 20 in the upper rows are locked by the weight load of the supporting portion 12, as soon as all non-permanent elements or portions dissolve and the construction 10 settles to an enduring and final solid state.

[0154] In a preferred solution as also shown in FIG. 9, the outer covering portion 14 grounds on a furrow 84 which may be about 40 cm deep into the ground or which may have a depth of about ⅓ of the height of the construction 10.

[0155] The furrow 84 may comprise stamped solid material pieces 86, and optionally also a solid foundation element 88. The solid foundation element 88 may be embedded in the solid material pieces 86 and may be provided as a curbside or a plastic element.

[0156] In order to prevent drainage water flowing through the solid material pieces 16 from entering the ground between the two furrows 84, a drip pan 90 may be applied below the supporting portion 12 for catching the water and other residues.
