Description

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

[0001] The present disclosure relates to a removable base for a building element, a kit and a method for manufacturing such a base. Prior art

[0002] To address ecological challenges and global warming, residential and commercial buildings must increasingly aim, through their design and equipment, to reduce their environmental impact both during their use, during their manufacture and during their destruction at the end of their life. Regarding the water supply, a known solution consists of equipping buildings with rainwater recovery tanks. However, the tanks known from standard industrial-scale solutions are generally made of concrete or plastic, are very bulky and are difficult to transport, particularly on land that is difficult to access. In addition, these tanks generally encroach significantly on the land, so that this solution is not suitable for buildings constructed on small plots or with very little outdoor space, particularly for equipping buildings that have already been constructed.Furthermore, once installed, given their size, these known tanks generally remain in place and can hardly be reinstalled elsewhere. Finally, when these known tanks reach the end of their life, they generally cannot be moved without being destroyed: either they remain in place or they are destroyed at the cost of sometimes substantial work.

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

[0004] One embodiment relates to a removable base for a building element comprising a bottom wall configured to be arranged facing a ground, a peripheral enclosure wall configured to support the building element and a cover wall, the bottom wall, the peripheral enclosure wall and the cover wall delimiting an internal volume and forming a reservoir configured to receive water.

[0005] For the purposes of this disclosure, “building element” means a terrace, a pergola, a kiosk, a prefabricated bungalow, a modular construction, etc.

[0006] Generally speaking, by "base" we mean any lower part of a building, placed directly on the ground or on any foundations. Subsequently and unless otherwise indicated, by "base" we specifically mean "removable base of a building element".

[0007] The bottom wall may be in direct contact with the ground, or arranged on any intermediate element. The bottom wall may comprise one or more panels. The cover wall is arranged above the bottom wall, the direction of gravity (i.e. Earth's gravity) being oriented from above to below, and may extend parallel to the bottom wall, but not necessarily. The cover wall closes the tank, for example in a sealed 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 surrounding peripheral 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 base, delimited by the bottom wall, the cover wall, and the peripheral enclosure wall. The cover wall and / or the peripheral enclosure wall may include a manhole, for inspection of the tank. In all cases, with the exception of the water inlet(s) and outlet(s), the tank may be sealed, for example to prevent the intrusion of insects, for example mosquitoes. Hereinafter and unless otherwise indicated, "peripheral wall" means "peripheral enclosure wall".

[0008] The tank may, for example, form a rainwater recovery tank (rainwater that has not come into contact with the ground), and / or stormwater (rainwater that has come into contact with the ground) and / or graywater. As a reminder, graywater is slightly polluted domestic wastewater (for example, wastewater from a shower or sink, a washing machine, a dryer, etc.) and can be used for tasks that do not require absolutely clean water. In contrast to graywater, blackwater or sewage water includes fecal matter or other polluting substances that are more difficult to treat. For example, after recovery and storage in the tank, rainwater or stormwater can be used in toilet flushing, washing machines, watering, car washing, etc. For example, after recovery and storage in the tank, graywater can be used in toilet flushing.

[0009] The peripheral enclosure wall is a structural wall of the base which structurally supports the building element, directly or indirectly supports the mass of the building element as well as the forces induced by the latter. Intermediate elements, for example to distribute and distribute the forces on the entire peripheral wall can be arranged between the peripheral wall and the building element. For example, within the base, only the peripheral wall can be configured to support the building element. In other words, only the surrounding peripheral wall can be provided to support and bear the mass of the building element, as well as the forces induced by the latter

[0010] The base according to the present disclosure forming a reservoir for receiving water allows easier integration than the tanks known from the state of the art, the reservoir being integrated into an internal volume of the base. This allows for reduced space requirements on the plot where the building is located, and installation on plots where the building leaves little external space. In addition, in use, the reservoir almost systematically houses a minimal quantity of water.This allows for synergy between the base and the reservoir: the base, thanks to the peripheral wall, allows for maximum free volume to form the reservoir, while the water present in the reservoir adds mass to the base and naturally lowers its center of gravity (a liquid naturally moves 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 removable aspect makes it easy to transport the base, and therefore the tank formed by the latter, on site, in particular on land that is difficult to access, and further facilitates its integration within buildings / plots, for example within terraced townhouses with an outdoor space without direct access from the street. In other words, the base can be initially delivered disassembled, and be assembled on site during its manufacture / installation. This also makes it possible to improve the carbon footprint of the base compared to tanks of the state of the art, during its transport between its place of manufacture and its installation site. The base, and the tank formed by the latter, is also easily removable, which allows for subsequent reuse on another site or easy disposal at the end of its life. This can in particular improve the environmental impact of such a base during or at the end of its life.The tank base according to this disclosure can thus present improved structural integration in use and on-site integration during the installation and removal phases compared to state-of-the-art tanks.

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

[0013] Such a peripheral wall structure can be easily supplied as a kit, and be assembled on site, and then dismantled at the end of the basement's use. The columns can absorb both the pressure forces exerted by the water contained within the reservoir, via the panels, and the forces induced by the building element. The shapes, sections and dimensions of the columns are not limited. For example, the panels can be mounted on an internal side of the columns and delimit the internal volume of the base, while facings can be mounted on an external side of the columns, thanks to which the aesthetics of the base can be adapted as desired. Such a peripheral wall structure can improve structural integration in use and integration on site during the installation and removal phases of the base.

[0014] In some embodiments, the peripheral enclosure wall may have, viewed in a horizontal plane relative to the direction of gravity, a polygonal shape having a plurality of vertices, wherein 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] The secondary posts are arranged between the primary posts, between two vertices of the polygonal shape, along one side of the polygonal shape, and for all sides of the polygonal shape. For example, a primary post may be a post that is mechanically stronger than a secondary post. For example, a primary post may comprise 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. According to another example, a primary post may comprise an arrangement of two or more angle irons. By arranging such primary posts at the vertices of a polygonal shape, the mechanical strength of the base is reinforced, while limiting, thanks to the secondary posts, the size and mass of the elements to be transported for the installation and assembly of the base on site.Such a balance can contribute to structural integration in use and to on-site integration during the phases of installation and removal of the base.

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

[0017] Such belts can be easily supplied as a kit, and be assembled on site, and then dismantled at the end of the basement's use. The belts can participate in absorbing the pressure forces exerted by the water within the tank. The belts can reinforce the mechanical strength of the basement, while limiting the size and mass of the elements to be transported for the installation and assembly of the basement on site. Such a balance can contribute to the structural integration in use and to the integration on site during the phases of installation and removal of the basement. For example, panels can be mounted on an internal side of the belts and delimit the internal volume of the base, while facings can be mounted on an external side of the belts, thanks to which the aesthetics of the base can be adapted as desired.

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

[0019] For example, the ends of the posts can be directly fixed to the belts, or by means of fixing plates. For example, the posts can be arranged above the lower belt and below the upper belt. This allows the forces to be transmitted directly via the belts and the posts, minimizing the stresses on the fixings between the posts and the belts.

[0020] Such an assembly structure between the posts and the belts can make it possible to reinforce the mechanical strength of the base, while limiting the size and mass of the elements to be transported for the installation and assembly of the base on site. Such a balance can contribute to the structural integration in use and to the integration on site during the phases of installation and removal of the base.

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

[0022] Such joists can be easily supplied in a kit, and be assembled on site, and then dismantled at the end of the use of the base. The joists can make it possible to form an air gap between the bottom wall and the ground and to insulate the rest of the base from the ground, avoiding rising damp or excessive thermal conductivity between the ground and the inside of the tank to prevent the water from freezing within the tank. The joists can make it possible to improve the horizontal leveling of the base. This can help to improve the structural integration in use and the integration on site during the phases of installation and removal of the base, as well as the durability over time.

[0023] In some embodiments, each joist may be mounted on a plurality of brackets configured to be disposed between the joist and the floor.

[0024] Such supports can be easily supplied in a kit, and be assembled on site, and then dismantled at the end of the use of the base. For example, the supports can be pads placed on the ground or piles driven into the ground. Such supports can make it possible to isolate the joists from the ground, preventing rising damp and facilitating the horizontal leveling of the base. This can help to improve the structural integration in use and the integration on site during the phases of installation and removal of the base, as well as the resistance over time.

[0025] In certain embodiments, the removable base of the building element may comprise 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 disclosure, a liner refers to any type of coating forming an internal layer of the tank, continuous and waterproof. For example, the liner may be a plastic tarpaulin (or polymeric material), for example ethylene-propylene-diene-monomer, also known by the acronym EPDM.

[0027] Such a liner can be easily supplied in a kit, and be assembled on site, and then disassembled at the end of the use of the base. It can help to improve the structural integration in use and the integration on site during the phases of installation and removal of the base, and maintain the watertightness of the tank over time.

[0028] In some embodiments, the removable building element base may include a plurality of beams disposed above the cover wall, the plurality of beams cooperating with the surrounding perimeter wall, the plurality of beams being configured to receive the building element, the direction of gravity being oriented from above to below.

[0029] Such beams can be easily supplied in a kit, and be assembled on site, and then disassembled at the end of use of the base. The beams of the plurality of beams can be supported directly or indirectly on the peripheral wall. The building element can be mounted on the beams, and the beams distribute the forces induced by the building element on the peripheral wall. The beams can increase the versatility of the base and the variety of building elements that can be mounted on the base. The beams can help to improve the structural integration in use and the integration on site during the phases of installation and removal of the base.

[0030] In some embodiments, the bottom wall, the surrounding perimeter wall and / or the cover 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, and be assembled on site, and then dismantled at the end of the base's use. The wooden panels can be of any type, solid wood, chipboard, wood particle board, glued laminated wood, laminate, MDF (medium density fiberboard), plywood, melamine, etc. The sandwich panels can be of any type, and comprise at least two layers of identical or different materials. For example, the sandwich panels can comprise a layer of thermal insulation, for example polyurethane foam or polystyrene, and an outer layer providing a certain mechanical resistance, for example a sheet of aluminum. These panels delimiting the enclosure forming the tank have no aesthetic impact or a limited impact, they can for example come from a recycling or reuse circuit, and be for example scrap facing panels which are perfectly functional but have aesthetic defects such as scratches or other. The panels can help to improve structural integration in use and integration on site during the installation and removal phases, and improve the environmental impact.

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

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

[0034] Such a framework, made entirely or partly of wood or aluminum, can be easily supplied as a kit, and assembled on site, and then dismantled at the end of the base's use. Furthermore, wood and aluminum are materials that are easy to transport and implement, and are particularly durable. Such a framework can allow panels to be mounted on an internal side in order to delimit the internal volume of the base, while facings can be mounted on an external side, thanks to which the aesthetics of the base can be adapted as desired. Such a framework can help to improve structural integration in use and integration on site during the phases of installation and removal of the base.

[0035] One 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 of a building element according to any one of the embodiments described in the present disclosure.

[0036] For example, the plurality of elements may include the possible posts, panels, belts, facings, mentioned above, as well as the screws and any associated hardware. For example, certain elements may be assembled together by screwing while other elements, such as for example 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 particularly rapid assembly of the base on site, for example between a maximum of one hour and a half (1h30) and two hours (2h00) for one or two people.

[0038] One embodiment relates to a method of manufacturing (or assembling) a removable base of a building element according to any one of the embodiments described in the present disclosure, in which at least one kit is provided according to any one of the embodiments described in the present disclosure and a closed reservoir configured to receive water and having a peripheral enclosing wall configured to support the building element.

[0039] One embodiment relates to an assembly comprising a removable base of a building element according to any one of the embodiments described in the present disclosure, and a building element mounted on said base. Brief description of the drawings

[0040] The object of the present disclosure and its advantages will be better understood upon reading the detailed description given below of different embodiments given as non-limiting examples. This description refers to the appended pages of figures, in which:

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

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

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

[0044] [Fig.4] [Fig.4] represents a variant of the base. Description of the embodiments

[0045] [Fig.l] shows an assembly 200 comprising a removable base of building element 10, in this example four bases 10 (only three being visible in [Fig.l]), and a building element 100, in this example three building elements 100. In this example, a first base 10 carries a pergola 100A as an example of building element 100, a second base 10 carries a terrace 100B as another example of building element 100, and two other bases 10 (only one being visible), together carry a modular construction or prefabricated bungalow 100C as yet another example of building element 100. According to a variant not shown, a base 10 and the building element 100 that it carries can be attached to a traditional building made of concrete / rubble / bricks / stones, etc. (a “solid” building), but not necessarily.

[0046] In [Fig.l], the bases 10 are each provided with facings 11, in this example plates, retracting 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 facing each other are not equipped with facing. The base 10 carrying the terrace 100b is shown partially cut away, so that the frame 50 is partially visible, as well as beams 40.

[0047] The bases 10 being in this example all identical, a single 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 arranged facing a ground SO, a peripheral enclosure wall 14 configured to support a building element 100 and a cover wall 16, the bottom wall 12, the peripheral enclosure wall 14 and the cover wall 16 delimiting an internal volume V and forming a reservoir 18 configured to receive water (the water not being shown in the figures), for example rainwater and / or storm water and / or grey water. In this example, with the exception of the water inlet(s) and outlet(s) not shown, the reservoir 18 is completely closed and watertight.

[0049] In this example, the peripheral enclosure wall 14 comprises a plurality of posts 20 extending vertically relative 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 peripheral enclosure wall 14 has, considered in a horizontal plane H relative to the direction of gravity G (and parallel to the ground SO), 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 arranged at each vertex S of the polygonal shape, and secondary posts 20B arranged between the primary posts 20A.

[0050] In this example, the primary posts 20A comprise two angles 20A1, 20A2, a first angle 20A1 called internal partly receiving two panels 22 and forming a corner, and a second angle 20A2 called external, oriented in the same direction as the first angle 20A1 and delimiting an external corner of the structure of the base 10. In this example, the two angles 20A1 and 20A2 are fixed, in this example by welding, to an upper plate 20A3S and a lower plate 20A3I respectively forming the upper end 20S and the lower end 201 of the primary post 20A. The angles 20A1 and 20A2 as well as the lower plate 20A3I are shown in more detail in [Fig. 3], which corresponds to magnifying glass III of [Fig. 2]. In this example, the upper 20A3S and lower 20A3I plates are identical, which makes it easier to mount the 20A primary posts.

[0051] In this example, each secondary post 20B comprises a profile 20B1 of square cross-section, fixed, in this example by being fitted and welded, to an upper plate 20B2S and a lower plate 20B2I respectively forming 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 attached to the lower belt 241 and an upper end 20S attached to the upper belt 24S.

[0054] In this example, the lower 241 and upper 24S belts are profiles of rectangular cross-section, and having grooves 23 (see [Fig.3]) for fixing the posts 20. Within the same 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 facilitate 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 engaged with complementary 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 belts 241 and 24S constitute the framework 50 of the base 10. The various profiles of the posts 20 and the belts 241 and 24S as well as the plates are made of aluminum. The framework 50 of this example is thus entirely or partly made of aluminum.

[0057] In this example, the bottom wall 12, the peripheral enclosure wall 14, and the cover 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 peripheral wall 14 between two vertices S comprises a single panel 22, in this example a single sandwich panel. For example, the cover wall 16 comprises two sandwich panels 17 joined together using a connector 17A. In this example, the cover wall 16 has a manhole 16A, which in this example is sealed. The bottom wall 12 may be identical to the cover wall 16 and comprise two sandwich panels joined by a connector, except for the presence of the manhole 16A.For example, the panels 17 may have the same dimensions as the panels 22, which can facilitate the packaging of the base 10 in kit form, as well as the assembly.

[0058] The panels of the bottom wall 16, and therefore the bottom wall 16, can be placed directly on the ground, and surrounded (or encircled) by the lower belt 241, itself placed directly on the ground. The panels 22 of the peripheral wall 14 can be screwed onto all or part of the posts 20 of the plurality of posts 20, and / or onto the lower belt 241 and / or onto the upper belt 24S. The panels 17 of the upper wall 16, and therefore the upper wall 16, can be placed 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 belt 24S, and can be screwed onto the upper belt 24S, but not necessarily.

[0059] In this example, a liner 26 may 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 may 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 may be equipped with a plurality of beams 40 arranged above the covering wall 16, the plurality of beams 40 cooperating with the peripheral 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 may be made of wood or aluminum. In this example, the assembly formed by the plurality of beams 40 may be fixed to the upper belt 24S, for example by screwing. In this example, the beams 40 form a frame flush with the outer periphery of the upper belt 24S, within which frame are arranged several beams 40 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 the 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 onto all or part of the plurality of posts 20 and / or onto the lower belt 241 and / or onto the upper belt 24S, and possibly onto the beams 40.

[0062] In this example, a kit K1 not shown, or shown assembled in [Fig. 2], for manufacturing the base 10, may comprise all of the elements described with reference to [Fig. 2], and in particular the plurality of posts 20, the profiles for forming the belts 241, 24S, the panels and panel connectors of the bottom wall 12 and the covering wall 16, the panels 22 of the peripheral wall 14, the liner 26, the optional beams 40, and all the associated screws and hardware if applicable. The kit K1 may also comprise facing plates 11. In other words, a kit K1 may comprise a plurality of elements configured to be assembled together in whole or in part by screwing to manufacture a base 10.

[0063] From such a kit K1, to proceed with the manufacture of a base 10, a closed tank 18 is manufactured, configured to receive water, in particular closed thanks to the covering 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 reference to [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 signs. In [Fig.4], the covering wall 16 is not shown, but the base 10' includes such a wall. Similarly, in [Fig.4] the beams 40 are not shown, but the base 10' is provided with such beams.

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

[0066] In this example, the base 10' comprises a plurality of joists 30 configured to be arranged between the bottom wall 12 and the ground. The joists may be made of aluminum or wood. In the example of [Fig.4], the joists may be made of wood, for example formed of boards having the same section as the boards forming the posts 20' and the belts 24'1 and 24'S. In this example, each joist 30 is mounted on a plurality of supports 32 configured to be arranged 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 driving. According to a variant not shown, the piles may have a screw thread, and be driven into the ground by screwing. The joists 30 may be fixed on the supports 32, in this example on the heads of the piles.

[0067] The panels not shown of the back wall, or more generally the back wall, can be fixed by screwing onto the joists 30. The lower belt 24'1 can encircle the back wall and be fixed by screwing onto the joists 30. The posts 20' can be screwed onto the lower belt 24'1, either directly or by means of brackets or any other hardware element. The panels 22' are fixed by screwing onto the posts 20'. In this example, the joists extend under the panels 22' and under the lower belt 24'1. A joist 30 can be arranged at right angles to the panels 22' extending parallel to the joists 30. The 24'S upper belt can be screwed onto the 20' posts. The panels not shown of the cover wall, or more generally the cover wall, can be placed or fixed by screwing onto the 24'S upper belt or onto the edge of the 22' panels.

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

[0069] From such a kit K2, to proceed with the manufacture of a base 10', a closed tank 18 is manufactured, configured to receive water, in particular closed thanks to the covering 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 obvious that modifications and changes may be made to these examples without departing from the general scope of the invention as defined by the claims.
