Description

Title of the invention: Removable base for a building element, kit and method for manufacturing such a base. Technical field

[0001] The present exposition relates to a removable base for a building element, a kit and a method for manufacturing such a base. Previous technique

[0002] To address environmental challenges and climate change, residential and commercial buildings must increasingly aim, through their design and equipment, to reduce their environmental impact during use, manufacturing, and end-of-life disposal. Regarding water supply, a known solution is to equip buildings with rainwater harvesting tanks. However, the tanks used in standard industrial-scale solutions are generally made of concrete or plastic, are bulky, and difficult to transport, particularly on hard-to-reach sites. Furthermore, these tanks typically take up a significant amount of land, making this solution unsuitable for buildings on small plots or with very limited outdoor space, especially for equipping existing buildings.Furthermore, once installed, given their size, these known tanks generally remain permanently and can hardly be reinstalled elsewhere. Finally, when these known tanks reach the end of their lifespan, they generally cannot be moved without being destroyed: either they remain on site or they are destroyed, sometimes requiring significant work.

[0003] There is therefore a need for a rainwater harvesting system suitable for plots where the building leaves little outdoor space, and which allows for easier installation and possible removal. Description of the invention

[0004] One embodiment relates to a demountable base of a building element comprising a bottom wall configured to be arranged opposite a floor, a perimeter enclosure wall configured to support the building element and a cover wall, the bottom wall, the perimeter enclosure wall and the cover wall delimiting an internal volume and forming a reservoir configured to receive water.

[0005] For the purposes of this presentation, "building element" means a terrace, a pergola, a kiosk, a prefabricated bungalow, a modular building, etc.

[0006] Generally speaking, "base" means any lower part of a building, resting directly on the ground or on any foundations. Hereafter, and unless otherwise specified, "base" specifically means "removable base of a building element".

[0007] The bottom wall may be in direct contact with the ground or placed on any intermediate element. The bottom wall may comprise one or more panels. The cover wall is positioned above the bottom wall, with the direction of gravity (i.e., Earth's gravity) oriented from top to bottom, and may, but not necessarily, extend parallel to the bottom wall. The cover wall encloses the tank, for example, in a watertight manner. The cover wall may comprise one or more panels. The bottom wall and the cover wall may extend horizontally with respect to the direction of gravity (i.e., Earth's gravity). The perimeter enclosure wall extends between the bottom wall and the cover wall, for example, vertically, parallel to the direction of gravity, for example, along the edges of the bottom and cover walls.The tank corresponds to an internal volume of the substructure, delimited by the bottom wall, the top wall, and the perimeter wall. The top wall and / or the perimeter wall may include a manhole for tank inspection. In all cases, with the exception of the water inlet(s) and outlet(s), the tank may be sealed watertight, for example, to prevent the intrusion of insects, such as mosquitoes. Hereafter, and unless otherwise specified, "peripheral wall" refers to the "peripheral wall."

[0008] The tank can, for example, serve as a rainwater harvesting tank (rainwater that has not contacted the ground), and / or a stormwater harvesting tank (rainwater that has contacted the ground), and / or a greywater harvesting tank. As a reminder, greywater is slightly polluted domestic wastewater (for example, water from a shower or sink, washing machine, dryer, etc.) and can be used for tasks that do not require absolutely clean water. In contrast to greywater, blackwater or sewage contains fecal matter or other pollutants that are more difficult to treat. For example, after collection and storage in the tank, rainwater or stormwater can be used for flushing toilets, washing machines, watering plants, washing cars, etc.

[0009] The perimeter wall is a structural wall of the foundation that structurally supports the building element, directly or indirectly supporting the mass of the building element as well as the forces induced by it. Intermediate elements, for example, to distribute and transfer the forces onto The entire perimeter wall can be positioned between the perimeter wall and the building element. For example, within the foundation, only the perimeter wall can be configured to support the building element. In other words, only the perimeter wall can be designed to support the mass of the building element, as well as the forces induced by it.

[0010] The foundation according to this description, forming a reservoir for receiving water, allows for easier integration than known prior art tanks, as the reservoir is integrated into an internal volume of the foundation. This allows for a reduced footprint on the plot where the building is located, and installation on plots where the building leaves little exterior space. Moreover, in use, the reservoir almost always holds a minimum quantity of water.This allows for a synergy between the base and the reservoir: the base, thanks to the peripheral wall, allows for a maximum free volume to form the reservoir, while the water present within the reservoir adds mass to the base and naturally lowers its center of gravity (a liquid naturally going by gravity to the lowest possible point), which reinforces the mechanical stability of the base, for example when a building element such as a pergola mounted on the base is subjected to strong winds.

[0011] The demountable design allows for easy transport of the base, and therefore the tank it forms, on-site, particularly on difficult-to-access terrain, and further facilitates its integration within buildings / plots, for example, within terraced houses with an outdoor space but no direct access from the street. In other words, the base can be initially delivered disassembled and assembled on-site during its manufacture / installation. This also improves the carbon footprint of the base compared to prior art tanks during its transport between the place of manufacture and the installation site. The base, and the tank it forms, is also easily demountable, allowing for subsequent reuse on another site or easy disposal at the end of its life. This can notably improve the environmental impact of such a base during or at the end of its life.The tank base described herein can thus offer improved structural integration in use and improved on-site integration during installation and removal phases compared to prior art tanks.

[0012] In some embodiments, the perimeter enclosure wall may comprise a plurality of posts extending vertically with respect to the direction of gravity, and a plurality of panels mounted on all or part of the plurality of posts.

[0013] Such a perimeter wall structure can be easily supplied as a kit, assembled on site, and then dismantled at the end of the substructure's use. The columns can withstand both the pressure exerted by the water within the reservoir, via the panels, and the forces induced by the building element itself. The shapes, sections, and dimensions of the columns are not limited. For example, panels can be mounted on the inside of the columns to define the internal volume of the base, while cladding can be mounted on the outside, allowing for customizable aesthetics of the base. Such a perimeter wall structure can improve structural integration during use and facilitate on-site integration during the installation and removal phases of the base.

[0014] In certain embodiments, the perimeter wall of the enclosure may have, considered in a horizontal plane with respect to the direction of gravity, a polygonal shape having a plurality of vertices, in which the plurality of posts includes a primary post disposed at each vertex of the polygonal shape, and secondary posts disposed between the primary posts.

[0015] Secondary posts are arranged between primary posts, between two vertices of the polygonal shape, along one side of the polygonal shape, and this arrangement is repeated for all sides of the polygonal shape. For example, a primary post may be mechanically stronger than a secondary post. For example, a primary post may consist of a single element or a set of several distinct elements. For example, a primary post may comprise an arrangement of two or more secondary posts. As another example, a primary post may comprise an arrangement of two or more angle brackets. By placing such primary posts at the vertices of a polygonal shape, the mechanical strength of the foundation is reinforced, while the secondary posts limit the size and mass of the elements to be transported for the installation and assembly of the foundation on site.Such a balance can contribute to structural integration in use and to on-site integration during the installation and removal phases of the substructure.

[0016] In some embodiments, the peripheral enclosure wall may include a lower belt and an upper belt arranged above the lower belt, the direction of gravity being oriented from top to bottom.

[0017] Such belts can be easily supplied as a kit, assembled on site, and then disassembled at the end of the base's service life. The belts can help to absorb the pressure forces exerted by the water within the tank. The belts can reinforce the mechanical strength of the base while limiting the size and weight of the components to be transported for the installation and assembly of the base on site. This balance can contribute to structural integration during use and to integration on site during the installation and removal phases of the base. For example, panels can be mounted on an inner side of the belts and delimit the internal volume of the base, while facings can be mounted on an external side of the belts, allowing the aesthetics of the base to be adapted at will.

[0018] In some embodiments, each of the posts in the plurality of posts can extend vertically between the lower belt and the upper belt and has a lower end fixed to the lower belt and an upper end fixed to the upper belt.

[0019] For example, the ends of the posts can be fixed directly to the beams, or via fixing plates. For example, the posts can be positioned above the lower beam and below the upper beam. This allows the forces to be transferred directly through the beams and the posts, minimizing stress on the fixings between the posts and the beams.

[0020] Such an assembly structure between the posts and the beams can strengthen the mechanical integrity of the base, while limiting the size and mass of the components to be transported for installation and assembly of the base on site. This balance can contribute to structural integration during use and to integration on site during the installation and removal phases of the base.

[0021] In some embodiments, the removable base of the building element may include a plurality of joists configured to be arranged between the bottom wall and the floor.

[0022] Such joists can be easily supplied in a kit, assembled on site, and then disassembled at the end of the base's service life. The joists can create an air gap between the bottom wall and the ground and insulate the rest of the base from the ground, preventing rising damp or excessive thermal conductivity between the ground and the inside of the tank, thus preventing the water inside the tank from freezing. The joists can also improve the horizontal leveling of the base. This can contribute to improved structural integration during use and on-site integration during the installation and removal phases of the base, as well as long-term durability.

[0023] In some embodiments, each joist can be mounted on a plurality of supports configured to be arranged between the joist and the ground.

[0024] Such supports can be readily supplied in a kit, assembled on site, and then dismantled at the end of the substructure's service life. For example, the supports could be pads placed on the ground or piles driven into the ground. Such supports can isolate the joists from the ground, preventing rising damp and facilitating horizontal leveling of the substructure. This can contribute to improved structural integration during use and on site integration. during the installation and removal phases of the base, as well as its long-term durability.

[0025] In certain embodiments, the removable base of the building element may include a liner (or sealing skin) forming the internal surface of the tank on the bottom wall and on the peripheral enclosure wall.

[0026] For the purposes of this description, a liner refers to any type of coating forming a continuous and watertight internal layer of the tank. For example, the liner may be a plastic (or polymeric) tarpaulin, for example made of ethylene-propylene-diene-monomer, also known by the acronym EPDM.

[0027] Such a liner can be easily supplied in a kit, installed on site, and then removed at the end of the base's service life. It can contribute to improving structural integration during use and on-site integration during the installation and removal phases of the base, and ensure the tank's watertightness over time.

[0028] In some embodiments, the removable base of the building element may comprise a plurality of beams arranged above the roof wall, the plurality of beams cooperating with the perimeter wall of the enclosure, the plurality of beams being configured to receive the building element, the direction of gravity being oriented from top to bottom.

[0029] Such beams can be readily supplied in a kit, assembled on-site, and then dismantled at the end of the foundation's service life. The beams of the plurality of beams can be directly or indirectly supported by the perimeter wall. The building element can be mounted on the beams, and the beams distribute the forces induced by the building element onto the perimeter wall. The beams can increase the versatility of the foundation and the variety of building elements that can be mounted on it. The beams can contribute to improved structural integration during use and on-site integration during the installation and removal phases of the foundation.

[0030] In some embodiments, the bottom wall, the perimeter enclosure wall and / or the roof wall may comprise one or more wooden panels and / or one or more sandwich panels.

[0031] Such panels can be easily supplied in a kit, assembled on site, and then disassembled at the end of the substructure's use. The wood panels can be of any type: solid wood, chipboard, particleboard, glulam, laminate, MDF (medium-density fiberboard), plywood, melamine, etc. The sandwich panels can be of any type and comprise at least two layers of the same or different materials. For example, sandwich panels may comprise a thermal insulation layer, for example, polyurethane foam or polystyrene, and an outer layer providing mechanical resistance, for example, a sheet These aluminum panels, which define the enclosure of the tank, have no aesthetic impact or a limited impact. They can, for example, come from a recycling or reuse program, and be, for instance, offcuts of cladding panels that are perfectly functional but have aesthetic defects such as scratches. The panels can contribute to improving structural integration during use and on-site integration during installation and removal, and improve the environmental impact.

[0032] In certain embodiments, the removable base of the building element may include a frame made entirely or partly of wood or aluminum.

[0033] The term "framework" refers to any structural element of the foundation. For example, any posts and any beams described above may be elements of the framework, or even constitute the framework itself.

[0034] Such a framework, made entirely or partially of wood or aluminum, can be easily supplied as a kit, assembled on-site, and then dismantled at the end of the base's service life. Furthermore, wood and aluminum are easy to transport and work with, and are particularly durable. Such a framework allows for the mounting of panels on one internal side to define the internal volume of the base, while cladding can be mounted on the external side, thus allowing the base's aesthetics to be customized as desired. This framework can contribute to improved structural integration during use and to on-site integration during the installation and removal phases of the base.

[0035] An embodiment relates to a kit comprising a plurality of elements configured to be assembled together in whole or in part by screwing to manufacture a removable base for a building element according to any one of the embodiments described in this presentation.

[0036] For example, the plurality of elements may include the posts, panels, belts, and facings mentioned above, as well as the associated screws and hardware. For example, some elements may be assembled together by screwing, while other elements, such as adjacent panels, may be assembled by interlocking.

[0037] Such a kit where the elements are configured to be assembled together in whole or in part by screwing can allow a particularly rapid assembly of the base on site, for example between a maximum of one hour thirty (1h30) and two hours (2h00) by one or two people.

[0038] An embodiment relates to a method of manufacturing (or assembling) a demountable base for a building element according to any one of the embodiments described herein, wherein at least one kit is provided according to any one of the embodiments described herein and the base is manufactured a closed tank configured to receive water and having a perimeter enclosure wall configured to support the building element.

[0039] An embodiment relates to an assembly comprising a demountable base for a building element according to any one of the embodiments described herein, and a building element mounted on said base. Brief description of the drawings

[0040] The purpose of this presentation and its advantages will be better understood upon reading the detailed description below of various embodiments given by way of non-limiting examples. This description refers to the accompanying figure pages, on which:

[0041] [Fig-1] Fig. 1 represents an assembly comprising a base and a building element,

[0042] [Fig.2] [Fig.2] represents a partially cutaway perspective view of the sou base of the [Fig.l],

[0043] [Fig.3] [Fig.3] shows a detailed view of magnifying glass III of [Fig.2], and

[0044] [Fig.4] The [Fig.4] represents a variant of the base. Description of the implementation methods

[0045] Fig. 1 represents an assembly 200 comprising a demountable base of a building element 10, in this example four bases 10 (only three being visible in Fig. 1), and a building element 100, in this example three building elements 100. In this example, a first base 10 supports a pergola 100A as an example of a building element 100, a second base 10 supports a terrace 100B as another example of a building element 100, and two other bases 10 (only one being visible), together support a modular construction or prefabricated bungalow 100C as yet another example of a building element 100. According to an unrepresented variant, a base 10 and the building element 100 it supports can be attached to a traditional building made of concrete / rubble / bricks / stones, etc. (a "permanent" building), but not necessarily.

[0046] In [Fig. 1], the bases 10 are each fitted with facings 11, in this example plates, concealing the structure of each of the bases 10. In this example, the bases 10 can be fixed together to form a homogeneous block of bases, but not necessarily. In this example, the faces of the different bases 10 opposite each other are not fitted with facings. The base 10 supporting the terrace 100b is shown partially cut away, so that the framework 50 is partially visible, as well as beams 40.

[0047] Since the bases 10 in this example are all identical, only one base 10 is described in more detail with reference to [Fig. 2]. This description applies to all the bases 10 of the present example. In [Fig.2], the base 10 is shown without facing 11.

[0048] The base 10 comprises a bottom wall 12 configured to be positioned opposite a floor SO, a perimeter enclosure wall 14 configured to support a building element 100, and a roof wall 16. The bottom wall 12, the perimeter enclosure wall 14, and the roof wall 16 delimit an internal volume V and form a reservoir 18 configured to receive water (the water not being shown in the figures), for example, rainwater and / or stormwater and / or greywater. In this example, with the exception of the unshown water inlet(s) and outlet(s), the reservoir 18 is completely enclosed and watertight.

[0049] In this example, the perimeter enclosure wall 14 comprises a plurality of posts 20 extending vertically with respect to the direction of gravity G (i.e. parallel to the direction of gravity G), and a plurality of panels 22 mounted on all or part of the plurality of posts 20. In this example, the perimeter enclosure wall 14, considered in a horizontal plane H with respect to the direction of gravity G (and parallel to the ground SO), has a polygonal shape, in this example a rectangular shape, having a plurality of vertices S, in this example four vertices S, in which the plurality of posts 20 comprises a primary post 20A disposed at each vertex S of the polygonal shape, and secondary posts 20B disposed between the primary posts 20A.

[0050] In this example, the primary posts 20A comprise two angle brackets 20A1, 20A2, a first angle bracket 20A1, referred to as internal, partially receiving two panels 22 and forming a corner, and a second angle bracket 20A2, referred to as external, oriented in the same direction as the first angle bracket 20A1 and defining an external corner of the base structure 10. In this example, the two angle brackets 20A1 and 20A2 are fixed, in this example by welding, to an upper plate 20A3S and a lower plate 20A3I forming respectively the upper end 20S and the lower end 201 of the primary post 20A. The angle brackets 20A1 and 20A2 as well as the lower plate 20A3I are shown in more detail in [Fig. 3], which corresponds to magnification III of [Fig. 2]. In this example, the upper 20A3S and lower 20A3I plates are identical, which facilitates the assembly of the 20A primary posts.

[0051] In this example, each secondary post 20B comprises a profile 20B1 with a square cross-section, fixed, in this example by being fitted and welded, to an upper plate 20B2S and a lower plate 20B2I forming respectively the upper end 20S and the lower end 201 of the secondary post 20B.

[0052] In this example, the peripheral enclosure wall 14 comprises a lower belt 241 and an upper belt 24S arranged above the lower belt 241, the direction of gravity G being oriented from the top DU to the bottom DO.

[0053] In this example, each of the posts 20 of the plurality of posts 20 extends vertically between the lower belt 241 and the upper belt 24S and has a lower end 201 fixed to the lower belt 241 and an upper end 20S fixed to the upper belt 24S.

[0054] In this example, the lower 241 and upper 24S belts are rectangular cross-section profiles with grooves 23 (see [Fig. 3]) for attaching the posts 20. Within each belt, the profiles are assembled by screwing, for example using bolts (not shown). The lower 241 and upper 24S belts can be identical, which can simplify assembly.

[0055] In this example, the posts 20 are arranged above the lower belt 241 and below the upper belt 24S. The posts 20 are fixed by screwing to the belts, via the plates, screws 19 engaging with additional locking elements not shown arranged in the grooves 23 of the belts 241, 24S (see [Fig.3] which illustrates such an assembly for the example of a primary post 20A).

[0056] In this example, the posts 20 and the beams 241 and 24S constitute the framework 50 of the base 10. The various profiles of the posts 20 and the beams 241 and 24S, as well as the base plates, are made of aluminum. The framework 50 in this example is thus made entirely or partially of aluminum.

[0057] In this example, the bottom wall 12, the perimeter enclosure wall 14, and the roof wall 16 each comprise a plurality of sandwich panels, for example, sandwich panels comprising a central core of polyurethane foam or polystyrene, and two outer layers enclosing the central core, made of aluminum. For example, each side of the perimeter wall 14 between two vertices S comprises a single panel 22, in this example a single sandwich panel. For example, the roof wall 16 comprises two sandwich panels 17 joined together by means of a fitting 17A. In this example, the roof wall 16 has a manhole 16A, which in this example is sealed. The bottom wall 12 can be identical to the roof wall 16 and comprise two sandwich panels joined by a fitting, except for the presence of the manhole 16A.For example, panels 17 can have the same dimensions as panels 22, which can facilitate the packaging of the base 10 kit, as well as its assembly.

[0058] The panels of the bottom wall 16, and therefore the bottom wall 16, can be laid directly on the ground and surrounded (or encircled) by the lower band 241, itself laid directly on the ground. The panels 22 of the perimeter wall 14 can be screwed onto all or part of the posts 20 of the plurality of posts 20, and / or onto the lower band 241 and / or onto the upper band 24S. The panels 17 of the upper wall 16, and therefore the upper wall 16, can be laid directly on the edge of the peripheral wall 14, in this example on the edge of the panels 22. According to a variant, the upper wall 16 can be placed on the upper band 24S, and can be screwed onto the upper band 24S, but not necessarily.

[0059] In this example, a liner 26 can form the internal surface of the tank 18 on the bottom wall 12 and on the peripheral enclosure wall 14. For example, the liner 26 can be an elastic EPDM tarpaulin fixed to the peripheral wall 14, for example on the upper belt 24S, via a fixing device 26A known elsewhere.

[0060] In this example, the base 10 can be equipped with a plurality of beams 40 arranged above the roof wall 16, the plurality of beams 40 cooperating with the perimeter enclosure wall 14, the plurality of beams 40 being configured to receive the building element 100, the direction of gravity G being oriented from the top DU to the bottom DO. The beams 40 can be made of wood or aluminum. In this example, the assembly formed by the plurality of beams 40 can be fixed to the top ring 24S, for example by screwing. In this example, the beams 40 form a frame flush with the outer perimeter of the top ring 24S, within which several beams 40 are arranged parallel to one side of the frame, and regularly spaced from one another.Depending on the type of building element 100 that the base 10 receives, the dimensions and mass of the building element 100, the beams 40 can be omitted and the building element 100 can rest directly on the peripheral wall 14.

[0061] The facing plates 11 can be fixed to the frame 50 by any means known elsewhere, for example by direct screwing on all or part of the plurality of posts 20 and / or on the lower ring 241 and / or on the upper ring 24S, and possibly on the beams 40.

[0062] In this example, a kit Kl, either not shown or shown assembled in [Fig. 2], for constructing the base 10, may include all the elements described with reference to [Fig. 2], and in particular the plurality of posts 20, the profiles for forming the beams 241, 24S, the panels and panel connectors of the bottom wall 12 and the roof wall 16, the panels 22 of the perimeter wall 14, the liner 26, the optional beams 40, and all associated screws and hardware. The kit Kl may also include facing panels 11. In other words, a kit Kl may comprise a plurality of elements configured to be assembled together, in whole or in part, by screwing to construct a base 10.

[0063] From such a kit Kl, in order to proceed to the manufacture of a base 10, a closed reservoir 18 is manufactured, configured to receive water, in particular closed by means of the cover wall 16, and having a peripheral enclosure wall 14 configured to support the building element 100.

[0064] A variant 10' of the base 10 of [Fig.2] will now be described in See Fig. 4. The base 10' of Fig. 4 is similar to the base 10 of Fig. 2, and the common elements are not described again and retain the same reference symbols. The roof wall 16 is not shown in Fig. 4, but the base 10' includes such a wall. Similarly, the beams 40 are not shown in Fig. 4, but the base 10' is equipped with such beams.

[0065] In the example of [Fig. 4], the walls 22' are made of wood, as are the panels of the back and roof walls. The beams 40, not shown in [Fig. 4], may be made of wood. The plurality of posts 20 comprises secondary posts 20B' formed from wooden planks and primary posts 20A' formed by two secondary posts 20B' joined together to present an L-shaped cross-section. The lower 24'1 and upper 24'S beams are formed from wooden planks. For example, the posts 20' and the beams 24'1 and 24'S may be formed from planks having the same cross-section, which may facilitate the assembly and packaging of the base 10' in kit form. In this example, the 20' posts and the 24'1 and 24'S beams form the 50 frame of the 10' base. The 50 frame in this example is thus made entirely or partially of wood. Note that on the [Fig.4] The upper 20'S belt is partially shown to reveal the arrangement of the 20' posts.

[0066] In this example, the substructure 10' comprises a plurality of joists 30 configured to be positioned between the bottom wall 12 and the ground. The joists may be made of aluminum or wood. In the example in [Fig. 4], the joists may be made of wood, for example, formed from boards having the same cross-section as the boards forming the posts 20' and the beams 24'1 and 24'S. In this example, each joist 30 is mounted on a plurality of supports 32 configured to be positioned between the joist 30 and the ground. In this example, the supports 32 are piles configured to be driven into the ground, for example, by hammering. According to an alternative not shown, the piles may have a threaded end and be driven into the ground by screwing. The joists 30 may be attached to the supports 32, in this example to the heads of the piles.

[0067] The unshown panels of the back wall, or more generally the back wall itself, can be screwed to the joists 30. The bottom rail 24'1 can encircle the back wall and be screwed to the joists 30. The posts 20' can be screwed to the bottom rail 24'1, either directly or by means of brackets or other hardware. The panels 22' are screwed to the posts 20'. In this example, the joists extend under the panels 22' and under the bottom rail 24'1. A joist 30 can be positioned directly above the panels 22' extending parallel to the joists 30. The The 24'S top band can be screwed onto the 20' posts. The unshown panels of the roof wall, or more generally the roof wall, can be laid or fixed by screwing onto the 24'S top band or onto the edge of the 22' panels.

[0068] In this example, a K2 kit, not shown or shown partially assembled in [Fig. 4], for constructing the base 10', may include all the elements described with reference to [Fig. 4], and in particular the plurality of posts 20', the boards for forming the girders 24'1, 24'S, the bottom wall panels, the roof wall panels, the perimeter wall panels 22' 14, the liner 26, the optional beams 40, the joists 30 and the supports 32, and all the associated screws and hardware. The K2 kit may also include facing panels 11. In other words, a K2 kit may include a plurality of elements configured to be assembled together, in whole or in part, by screwing to construct a base 10'.

[0069] From such a K2 kit, to proceed to the manufacture of a base 10', a closed reservoir 18 is manufactured, configured to receive water, in particular closed by means of the cover wall, and having a peripheral enclosure wall 14 configured to support the building element 100.

[0070] Although the present invention has been described with reference to specific embodiments, it is evident that modifications and changes can be made to these examples without departing from the general scope of the invention as defined by the claims. In particular, individual features of the various embodiments illustrated / mentioned can be combined in additional embodiments. Therefore, the description and drawings should be considered in an illustrative rather than a restrictive sense.

[0071] For example, the substructure may include wood panels and sandwich panels. For example, a substructure such as that shown in [Fig. 2] may include a plurality of joists, themselves possibly mounted on a plurality of supports, as in the example in [Fig. 4].
