TECHNICAL FIELD

[0002] The present invention relates generally to the field of building construction. More specifically, the invention relates to building materials and methods of building construction.

BACKGROUND

[0003] Generally, building is costly, laborious and time-consuming. Hence, the need for greater efficiency, less labour-intensive processes and cheaper building materials and methods.

[0004] Traditionally, sand-bags have been used to build some structures, but these structures were usually only temporary. There are drawbacks of using sandbags. Firstly, they have low tensile strength, and because of this, any structures made from sandbags tend to be for unimportant structures. Secondly, sand-bags tend to deteriorate, which makes them impractical for permanent structures.

[0005] An advanced way for building the structures is to use ‘conventional bags combined with barbed wire’ as disclosed in U.S. Patent No. 5,934,027. The method usually involves filling standard-sized bags from one end, laying them horizontally and compacting them. The fill is usually not only sand but a composite material that has greater cohesiveness. This material is sometimes stabilised with cement or lime. Sometimes the bags are open-ended fabric tubes, with folds on each end to contain the earth. This methodology discloses the use of long bags too. Sometimes strands of barbed wire are used between courses to provide tensile strength and shear capabilities. Prior to this method and since, sandbags and similar technologies have been used in the construction of dams, dykes, fortifications, retaining walls, drainage systems and other temporary constructions. This advancement enabled the technology for domestic-scale architecture, especially to create walls, vaults, cupolas, arches and domes. This methodology has a limitation that the bags used in it cannot be very long and continuous. Even if the bags are somehow longer, it is a challenge to fill them evenly, and with additional length, the process of filling and setting the courses becomes more labour intensive. Such limitations make the process of making the structures difficult, error-prone and time-consuming.

[0006] Hence, there is a need to provide a technique which can help to make construction faster, easier and cheaper.

SUMMARY OF THE INVENTION

[0007] The present invention relates to a building module, to be used for the construction of structures, which includes a fabric sheet, a filling material and a holding means. The fabric sheet wraps around the filling material to form folds over the filling material, with the edges of the wrap’s folds to be held in place by the holding means. The fact that these wraps can be continuously filled from above to make building modules that are otherwise functionally like the state of the art, means that the process of construction can be continuous and easy, rather than as a series of difficult, labour intensive steps. This enables structures to be constructed quickly and in a cost-effective way.

[0009] According to one embodiment of the building module, wherein the fabric sheet is made of a synthetic material or a natural fibre material, or combination thereof. Such fabric sheets provide longevity to the building module and reinforcing to add tensile strength and cohesiveness to the fill material, and therefore to provide better support to the structures where they are used.

[0010] According to another embodiment of the building module, wherein the filling material is a composite of at least one of sand, silt, clay, gravel, other types of earth material, organic material, recycled waste, bonding agents or combination thereof. Various combinations of the filling materials shall serve different purposes. Clay and other bonding agents are useful as they add extra cohesiveness because they glue particulates together. The other aggregates (silt, sand, gravel) stop clay from being too reactive (swelling with humid conditions and shrinking when dry). Sand and gravel also add compressive strength. Cement and lime add permanent, waterproof cohesiveness. In general, organic materials will not be used in construction except where they act as a bonding agent or fibre to improve tensile strength. On the other hand, organic materials might be used for different purposes again, such to make planters and retaining walls, where the fill is to enable plants to grow.

[0011] According to yet another embodiment of the building module, the building module includes a bonding agent. The bonding agent includes at least one of lime, clay, cement, proteins, gypsum, fibre or glue, or combination thereof.

[0012] According to one embodiment of the building module, wherein the filling material inside the wrap is compressed or compacted. This helps in making the building module stable which further provides stability to the structures in which they are used.

[0013] According to another embodiment of the building module, wherein the fabric sheet has edges which are folded up and over the filling material, one edge of the fabric over the other. This way of making the building module shall be helpful to make them as long (continuous), fillable from above, and easier to produce using continuous mechanical processes.

[0014] According to yet another embodiment of the building module, wherein the holding means are at least one of a stitching means or an adhesive, or a pinning means, or from the mass exerted by a subsequent building module over this module, or combination thereof. The stitching means and the pinning means are affixed to the wrap and penetrate both layers. Adhesive, where used, is provided between the two layers of the wrap. Such holding means allows versatility for the builders and provides an easy way to complete the building modules faster. [0015] According to one embodiment of the building module, where the building module needs to be extended beyond the cut length of the fabric sheet, additional fabric sheets can be added, such that at one end of the first fabric sheet, a start of a second fabric sheet is wrapped as one. Both the first fabric sheet and the second fabric sheet wrap around the filling material and the edges of at least one of the wraps are held by the holding means. This embodiment is helpful to extend building modules so that modules are not limited by lengths of the fabric sheet.

[0016] According to yet another embodiment of the building module, the fabric sheet is wrapped around the filling material in a spiral configuration such that folds are formed around the filling material about each turn of the spiral, and the edges of the wrap’s folds overlap along substantially each consecutive turn of the spiral. The folds run oblique to an axis of the building module, the overlapping edges run oblique to the axis of the building module, and the holding means run oblique to the axis of the fabric sheet and to the overlapping edges.

[0017] Another aspect of the present invention relates to a method for making a building module, which includes various steps. First, spreading a fabric sheet onto a base or a preceding course made of the building module. Second, placing a composite filling material into a form, which may be a container, wherein the container has an opening at the bottom of the container. Third, compressing the filling material from the top through a compressing means. Fourth, wrapping the fabric sheet up and over to the compressed material by folding one side of the fabric sheet along a length of the sheet and over another, and at the very ends, once the courses are complete, folding those over also. Fifth, providing a holding means to hold the wrapping of the fabric sheet firmly. This method can be implemented manually, in a semi-mechanized fashion, or in a completely mechanized fashion using standard formwork or a custom-made machine.

[0018] Another aspect of the present invention relates to a device for making a building module according. The device includes a filling means and a folding means. The filling means includes a top part having a top opening and a bottom part having a bottom opening, such that through the top opening, a composite filling material is filled through the bottom opening onto a fabric sheet. The folding means fold the edges of the fabric sheet, one over the other once the filling material is in place on the fabric sheet. Such a device helps to mechanize the process for making the building module, which helps to build the modules faster and more consistently.

[0019] According to one embodiment of the device, wherein the folding means is having two walls, such that to allow the filling means to slide between the walls folding means, leaving a gap to allow sides of the fabric sheet to pass through the gap. This embodiment further provides for an efficient mechanism to carry out the filling of the fill material, as well as folding of the sheet almost simultaneously, further automating the process and decreasing the time to make the building modules. This makes the handling of the long lengths of fabric sheeting easier and therefore the making the building module less fiddly.

[0020] According to another embodiment of the device, wherein the walls of the folding means are slidable over a base or a previous course of the building module. This shall help in the placement of the device easily on the previous course of the building module.

[0021] According to yet another embodiment of the device, the device includes one or more pairs of guiding means coupled to the walls of the folding means, which allows the device to be easily placed directly over a base or a previous course of the building module. Guiding means shall further simplify the placement of the device directly over the previous course of the building modules

[0022] According to one embodiment of the device, wherein the folding means includes two flanges, such that side edges of the fabric sheet when placed into the device shall be functionally coupled to each of the flanges. A front part of the flanges is outspread to allow spreading of the fabric sheet. In the middle section, the flanges are bent upwards (but still coupled to the fabric sheet) to create a form to receive and contain the filling material and to allow for compaction. The rear section of the flanges, still functionally coupled to the edges of the fabric sheet, fold again to become substantially parallel to each other, to complete the folds of the fabric sheet over the filling material. Such flanges enhance the automation of folding of the fabric sheet edges so the process can take place without human intervention. It makes the process of making building modules more mechanisable. [0023] According to another embodiment of the device, the device includes a compressing means which compresses the filling material once it is placed onto the fabric sheet through the filling means. The compressing means mechanize the steps of compressing the filling material, which further reduces the need for human intervention, therefore making the process of building the modules still more continuous, automatic, and fast.

[0024] According to yet another embodiment of the device, wherein the compressing means includes one or more compressing rollers to compress the filling material from above once it is placed onto the fabric sheet through the filling means. Rollers are used to compress the filling material by applying pressure to the rollers and rolling over it; a simple mechanism to compress the filling composite.

[0025] In other embodiments of the device, the compressing means includes one or more vibrating compactors to compresses the filling material once it is placed onto the fabric sheet through the filling means. Vibrating compactors are lighter, and are powered, but are a better way to compress the filling material.

[0026] According to yet another embodiment of the device, the device includes a holding means which is used to seal the wrap once it is formed by the folding ends of the fabric sheet over each other. The sealing is carried out using an adhesive, a pinning means or stitching means, or combination thereof. The stitching means and the pinning means penetrate both folds of the wrap. The adhesive is provided between the folds of the wrap. This embodiment provides for various options for holding means which can be used as per the requirements of a particular user or usage.

[0027] According to one embodiment of the device, wherein the pinning mechanism includes a pinning roller with grooves to allow a strip of pins or the spikes of barbed wire to pass through, pierce the fabric layers and embed the pins or spikes, and yet still protrude sufficiently to hold subsequent courses of the building module.

[0028] According to another embodiment of the device, wherein the pinning means are mounted into a track on the edges of to the two outspread flanges, such that the pins or spikes of the barbed wire are then embedded into the edges of the fabric sheet so the fabric sheet can be effectively held and directed. In the front part the flanges are outspread to allow spreading of the fabric, a middle part where the flanges are bent upwards to allow receipt of the filling material and compaction, and to a rear part, where the flanges fold over one another to become substantially parallel, to complete the fold, and finally embed the pins or barbs into the opposite side of the fabric sheet as the device progresses.

[0029] According to yet another embodiment of the device, the device includes one or more spools that hold the pinning mechanism or the barbed wire, and which is functionally coupled to a pinning roller, such that when the device moves, the spools supply the pins or the barbed wire to be continuously attached to the fabric sheet by the rollers.

[0030] According to one embodiment of the device, the device includes a sheet holder which holds the fabric sheet and is functionally coupled to the pinning rollers, such that when the device moves, the sheet holder passes on the fabric sheet to the pinning rollers.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0032] For the purpose of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the figures and specific language will be used to describe them. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Such alterations and further modifications in the illustrated system, and such further applications of the principles of the invention as would normally occur to those skilled in the art are to be construed as being within the scope of the present invention.

[0033] It will be understood by those skilled in the art that the foregoing general description and the following detailed description are exemplary and explanatory of the invention and are not intended to be restrictive thereof.

[0034] The terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process or method that comprises a list of steps does not include only those steps but may include other steps not expressly listed or inherent to such a process or method. Similarly, one or more sub-systems or elements or structures or components preceded by "comprises... a" does not, without more constraints, preclude the existence of other, sub-systems, elements, structures, components, additional subsystems, additional elements, additional structures or additional components. Appearances of the phrase "in an embodiment", "in another embodiment" and similar language throughout this specification may, but not necessarily do, all refer to the same embodiment.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention belongs. The system, methods, and examples provided herein are only illustrative and not intended to be limiting.

[0036] In the proposed technique of the invention, sides of a fabric sheet are folded in and held under subsequent course to make ‘wraps’ rather than bags. These wraps are basic building modules for building any kind of structures. These wraps are potentially pinned together with strands of barbed wire, with pins, staples, stakes etc or simply held by the pressure of subsequent courses. This technique allows the courses to be indefinitely long, or even continuous, where previously there were practical limits to potential length due to the fact that bags had to be filled evenly from the open end/ends. This technique enables continuous, easier and more even filling in situ and therefore faster, cheaper and better construction. The new technique has all the benefits of the prior art, without the frustrations of its process. Importantly, the technique better allows automation and mechanisation because it’s easy to employ machines and simple moving forms to enable linear, continuous processes. It is pertinent to note that the prior art cannot allow such mechanisation because it is difficult to fill the far ends and middle of bags evenly. Also, bags have to be furled in some way to fill them and unfurled as filling progresses. This places practical limitations on the length of single bags/voussoirs. The same problems won’t exist with this proposed technique.

[0037] Fig. 1 and Fig. 2 shows a sectional view of exemplary building modules 1 which are placed one over another. The building modules 1 of Fig. 2 also have barbed wires to pin down the building modules for securely closing them, and also binds modules together to provide strength to the structure. In Fig. 1 , the subsequent buildings to module 1 applies pressure to building module 1 beneath it, to provide resistance to hold the folds for keeping the building modules wrapped. Either of the exemplary modules of Fig.1 or Fig. 2 can be used, however the building modules 1 with barbed wires as in Fig. 2 have a definite advantage, because the barbed wire not only just holds the wraps, but also provides bonding between the building modules 1 , and can also be employed to functionally couple the fabric sheet to a manufacturing device.

[0038] These building modules 1 are made of fabric sheets 2, which wrap around the filling material 3 to form folds over the filling material 3, with edges 5 of the wrap’s folds are further held by a holding means 4. The holding means 4 in Fig.1 exemplary building module 1 is pressure applied by a subsequent building module 1 , and in Fig. 2 exemplary embodiment is the barbed wires 6.

[0039] The fabric sheet 2 has edges 5 which are folded up and over the filling material, one edge of the fabric over the other. Also, the filling material 3 inside the wrap is compressed or compacted to provide stability to the building module 1 . [0040] The fabric sheet can be of synthetic material or natural fibre material. Even a composite material of synthetic material and natural fibre material can also be used. Synthetic material can be any plastic, polythene or synthetic fibre such as fibreglass or metallic threads. The natural fibres are preferred in a scenario where structures are required to return the structure back to earth in an environmentally friendly way. One such great example of natural fibre material is hessian (linen/burlap). When rendered, it becomes permanent, and if left un-rendered or if the render is broken up, it will rot into the earth, which is great for temporary structures like formwork, shoring or damming. It is pertinent to be noted that any other kind of fabric material can also be used, however, the material used should have tensile strength.

[0041] The holding means 4 can be a stitching means or an adhesive, or a pinning means, or another building module kept over this module and any combination of the holding means 4 can be used to further strengthen holding capacity of the wraps. The stitching means and the pinning means are affixed to the wrap and penetrate both layers, as shown by the barbed wires in Fig. 2. The adhesive is provided between two layers of the wrap, so as to bind the two layers together. Adhesives can also be used between courses/modules/voussoirs.

[0042] The filling material can be sand, silt, clay, gravel, other types of earth material, organic material, recycled waste, bonding agents, and any combination of these types of filling materials. In one exemplary implementation, for walls, a formula of 25% sand, 25% clay, 25% silt and 25% gravel is ideal. In some other embodiments, a mixture including 10% cement can be used in filling material 3. It is pertinent to note that each of the filling materials have their own utility and advantages, which are mentioned further. Clay, glues, proteins, lime, fibres and cement add cohesiveness because they glue particulates together. The other aggregates (silt, sand, gravel) stop clay from being too reactive (swelling with humid conditions and shrinking when dry). Sand and gravel add compressive strength. Cement and lime add permanent, waterproof cohesiveness. Organic materials are avoided unless the structure is to be impermanent, but they can be useful for adding tensile strength, for example, fibre (straw, chaff, chopped fabric) has been used in earth building since time immemorial. [0043] Bonding agents can be lime, clay, cement, proteins, gypsum, fibre, glue, or combination of any of these bonding agents. Bonding agents provide permanent cohesiveness. They turn the wrap into a block as they set. Some of these materials are naturally present in mineral earth (like clay, lime), and the earth may need adjusting to get the profile ‘right’. This means special earths and agents might need to be added, and others sieved out. In the earth building industry, purists like to avoid chemical impurities like cement because of the relatively high carbon-footprint, added cost and the industrial processes involved. But engineers and authorities tend to like them because they add a safety factor to the technology.

[0044] It is pertinent to note that the building modules 1 can be indefinitely long. Even longer than a wall, if the wall is to have rounded corners or is a dome of sorts, in which case the whole structure can potentially be a single ‘spiral’.

[0045] In one embodiment, a building module 1 can be extended beyond the cut length of the first fabric sheet 2 by adding additional fabric sheets 2. Near the end of the first fabric sheet, a second fabric sheet starts and is wrapped with the first as if they were one. Both the first fabric sheet and the second fabric sheet wrap around the filling material together and the edges of at least one of the wraps are held by the holding means. This embodiment is helpful to extend building modules so that modules are not limited by lengths of the fabric sheet.

[0046] Fig. 3 shows a representation of a manual method to make the building modules. It involves laying a fabric sheet 2 over an existing course of building module 1 , over the ground, floor or over a foundation. The sheets don’t have to be continuous to deliver a continuous product. When one sheet ends, another can overlap it to continue. A bottomless container 8 is placed over the course. The container is filled with earth, sand or some other filling material 3. The filling material is compacted to structurally satisfactory levels using a compressing means 9, such as a tamper, a compactor, vibration or even by adding a fluid. One example of fluid as compacter/compressor is water, which needs to be added in any case, if the cohesion ingredient is cement, lime or another water-activated media. The first sheet edge 5 is folded in, then the second edge 5, then the wraps are pinned down with pins 7. Other holding means for holding the edges can be spikes, pegs, barbed wire, glue, stitching etc. The container 8 is then pulled forward to advance the process.

[0047] The technique of the invention can be implemented through a full mechanized device or semi-mechanized device. The device may include a filling means and a folding means. The filling means includes a top part having a top opening and a bottom part having a bottom opening. Through the top opening, the filling material or a composite of the filling material and a bonding agent is filled through the bottom opening onto a fabric sheet. The folding means fold edges of the fabric sheet on one over another when the filling material or the composite of the filling material and the bonding agent (if any is used) is placed onto the fabric sheet. Further procedure for compressing the filling material and fixing the edges of the fibre sheet one over another to hold the folds can be carried out manually or using further mechanisation.

[0048] In another embodiment, the device is also provided with a compressing means, which compresses the filling material when it is placed onto the fabric sheet through the filling means.

[0049] In one embodiment, the device is also provided with a holding means adapted to seal the wrap formed by the folding ends of the fabric sheet. The sealing is carried out using an adhesive, a pinning means or stitching means, or combination thereof. The stitching means and the pinning means are affixed on edges the wrap and penetrating both edges, while the adhesive is provided between two edges of the wrap.

[0050] Fig. 4 illustrates an exemplary semi-mechanised device 10 which is being used to make the building modules 1. This device 10 has a container 8 which is the filling means. This container has a top part having a top opening and a bottom part having a bottom opening. Through the top opening, a filling material is filled through the bottom opening onto a fabric sheet. This device 10 also has a folding means 1 1 which has two walls 12a, 12b. These walls 12a, 12b allow the filling means 8 to slide between the walls 12a, 12b leaving a narrow gap to allow for the sides of the fabric sheet 2 to pass through. The walls 12a, 12b fold over, to become a folding means 1 1 . These are slidable over a base or a previous course of the building module 1 . The folding means 1 1 might also include one or more pairs of guiding means 13 coupled to the walls 12a, 12b of the folding means 11 and allows the device 10 to be easily placed directly over a base or a previous course of the building module 1. In an alternate embodiment, the walls 12a, 12b need not be slidable on the previous course, rather the walls 12a, 12b are placed on to the previous course of one of the building module or foundation, and in such scenario, the user of the device has to apply their skills to appropriately move the device to place and create the building module. In one embodiment, the guiding means 13 are not provided, and the user has to use their skills for placing the device 10 over a base or a previous course of the building module 1 .

[0051] Fig. 5 illustrates a fully mechanised device 10 which is being used to make the building modules 1. It is a device 10 that has out-stretched flanges 14a, 14b at the front. These flanges 14a, 14b then turn upwards in the middle, and over one another at the back. The device 10 is bottomless at the middle and rear sections. The front of the device 10 is essentially a horizontal plane. It both spreads out a fabric sheet 2 and pushes the barbs of barbed wire 6 into the edges 5 of the fabric sheet 2 to make them graspable by the flanges 14a, 14b. In the middle (the next part) of the flange-machine, the flanges 14a, 14b turn upwards (here there is no bottom, just the stretched fabric 2). This open-handed U-shape, behaves like a container for the filling means above, enabling the filling of the filling material 3 conveniently and evenly. The filling material 3 is poured into the U-shape in the fabric sheet 2 and it can then be immediately compacted using a compressing roller 15, from both above, and from the flanges 14a, 14b to the sides. The flanges 14a, 14b, and with them the sheet’s edges 5, fold over one another, at which point a pin pushing roller 21 pushes the barbed wire 6 through the opposite folds of the fabric sheet 2 (one under, one over), thereby securing the fabric wrap in place around the compressed fill and directly above the previous course or base.

[0052] For compressing the filling material, a compressing roller 15 is provided which compresses the filling material 3 from above when it is placed onto the fabric sheet 2. In an alternate embodiment, for compressing the filling material, one or more vibrating compactors can be provided which compresses the material through vibration mechanism. The compressing roller 15 shall be heavy in weight and may additionally have spring-loading. [0053] The device 10 also includes a pinning roller 17 with one or more grooves 18 which allows barbs of a barbed wire 6 to pass through and to pierce and embed the barbs into fabric layers, and yet still protrude sufficiently to hold subsequent courses of a previous building module 1 .

[0054] The device further includes one or more spools 19 which hold the barbed wire 6 and is functionally coupled to the pinning rollers 17, such that when the device 10 moves, the spools 19 supply the barbed wire 6 to be continuously attached to the fabric sheet 2 by the set of pinning rollers 17.

[0055] The device also includes a sheet holder 20 which holds the fabric sheet 2 and is functionally coupled to the pinning rollers 17, such that when the device 10 moves, the sheet holder 20 passes on the fabric sheet 2 to the pinning rollers 17.

[0056] The filling can be carried out using an attached or separate unit. The filling can be carried by a person with a shovel, bucket or another manual device manually. However, to make the device completely automatic, a conveyor running from underneath a material hopper would be a good solution. Alternatively, the filling material can fall out of a hopper directly.

[0057] The device 10 can be moved by an external propulsion mechanism. A coupling 16 to which said external propulsion mechanism shall be connected, is provided onto the device 10.

[0058] According to another embodiment of the invention, there is provided a building module (1 ) consisting of a fabric sheet (2) wrapping around a filling material (3) in a spiral configuration, and held in place by a holding means (4). Folds are formed around the filling material (3) about each turn of the spiral. The edges (5) of the wrap’s folds overlap along substantially each consecutive turn of the spiral, as held in place by the holding means (4).

[0059] Accordingly there is provided a building module (1 ) wherein the folds run oblique to an axis of the building module (1 ), the overlapping edges (5) run oblique to an axis of the building module (1 ), and the holding means (4) run oblique to the axis of the fabric sheet (2) and to the overlapping edges (5).

[0060] It is worth saying that the wrap technique, used in the current invention, is more robust if finished with a render of some kind because plastics and natural fibres may be subject to deterioration in UV radiation (from sunlight), fire or physical damage. Paint can help with UV, and some coatings with fire also, but render is best. Render isn’t required for temporary walls, except to further stave off fire.

[0061] The modules can be used to form various kind of structures like building construction, landscapes, emergency structures, and many other types of structures. Some examples of building construction are walls, ground slabs, domes, cupolas, vaults, arches. Some examples of landscape uses are retaining walls, temporary retaining walls and terracing, planters, fencing/ farm walls, dykes, dams, water breaks, sea walls, irrigation channels, windbreaks, erosion control, soil stabilization structures, structures in place of gabions, and plant trails (where sets are pre-mixed into organic earth and there the fabric ‘breathable’ or organic). Some examples of emergency structures are fire breaks and flood levies. Other types of structures can include water tanks, silos, septic systems, construction on the lunar surface and other solid planets, and inexpensive mass (for counterweights etc.).
