Definitions

  • the present invention relates to an inflatable vault with a flexible poly-lobed double wall, of which only the air space between the two walls is pressurized, thus leaving the space which it covers at ambient pressure.
  • This vault is designed, among other things, to allow its deployment by simple inflation, as well as its retraction by deflation, which allows at will to cover a space in order to protect it from bad weather and to discover it in good weather.
  • Such an arch can be used to temporarily cover large-scale installations, such as stadiums with stands reserved for spectators. In this case, it represents an enormous area of fabric, weighing from fifty to one hundred tonnes, which it is impossible to carry out in the factory, to transport and to install in a single completely completed assembly.
  • the vault is made of several elements, it is wise, on the one hand, that these elements are completely completed and tested in the factory, in particular to check their tightness, and, on the other hand, that the mounting of these elements between them is easy, fast and does not require any expensive site equipment.
  • Patent FR-A-2 166 397 relates to an inflatable structure comprising a succession of inflatable boxes which bear on one another when they are inflated and which are placed between two plies to which they are fixed, said plies being stretched by the caissons during inflation of the structure. Given the design of this structure, it cannot be applied to large-scale constructions, which is one of the objectives which the present invention proposes to achieve.
  • FR-A-2 326 544 relates to a flexible inflatable structure consisting of a nave with at least two walls, deployable and foldable or retractable, composed of a series of contiguous, flattenable and pressurizable enclosures, the dividing walls of which separate the external and internal and possibly median walls of said nave.
  • the multiple elements making up the vault are therefore simple elementary panels of waterproof fabric which it is necessary to assemble on site to make continuous connections that are both resistant and waterproof over long lengths, which requires very close manufacturing tolerances. precise and an important and delicate work of assembly on site not guaranteeing the total reliability of the product obtained.
  • the present invention therefore aims to provide a vault resulting from the assembly of a plurality of inflatable beams fully prefabricated and tested in the factory, these beams being of low mass, easily foldable in packages easily transportable on truck and also can be assembled on site flat on the ground with rustic but reliable and quick to implement, even by unskilled labor, and without the use of lifting means or to scaffolding.
  • the present invention also aims to provide a vault which, despite its subdivision into multiple elements, incorporates pressurization means with variable geometry, large section, allowing inflation and rapid deployment.
  • the present invention therefore relates to an inflatable arch with a double poly-lobed wall, deployable and retractable, confining a layer of inter-wall air under pressure, characterized in that it is obtained by assembling, side by side, a plurality inflatable and separate hollow beams, each of said beams being formed by a flexible envelope integrating means ensuring the continuity of the sealing of the volume which it confines and comprising mainly at least two longitudinal panels, the surfaces of which intersect at least two longitudinal edges to the right of which said panels are not only connected to each other, but also connected to homologous panels of adjacent beams, using discontinuous mechanical means of connection.
  • the present invention also relates to an inflatable vault with a double poly-lobed wall, deployable and retractable confining a layer of interparois air under pressure and constituted by the assembly side by side of a plurality of hollow inflatable and separate peppers, characterized in that each beam is inflatable separately and is formed by a flexible envelope integrating means ensuring the continuity of the tightness of the volume which it confines and comprising four panels assembled at the corners, of which the two opposite panels are the soles and constitute one of the lobes of the inner wall and one of the lobes of the outer wall of said vault, while the other two intermediate panels are the cores and constitute the bracing ribs sealing the vault between two adjoining beams, said panels being interconnected by discontinuous mechanical connecting means also interconnecting the homologous panels of adjacent beams.
  • the discontinuous mechanical means for rapid connection of the inflatable beams to one another comprise, on the one hand, a series of flaps extending said panels along at least one of their longitudinal edges and each equipped with '' a bead bordering their free end and, on the other hand, a plurality of profiles comprising at most as many longitudinal grooves as panels to be joined, said profiles being threaded one behind the other, simultaneously from one end to the other of each of said flaps to join.
  • the means ensuring the continuity of the tightness of the volume confined by the flexible envelope of said beams are waterproof membranes connecting longitudinally to each other the internal faces of the two adjacent panels of each beam, on either side of their common connecting edge.
  • the invention also relates to a method of implementing the inflatable vault, characterized in that the construction of the vault is carried out by a first operation consisting in assembling together, using quick connection means, the panels of the plurality of deflated beams, laid flat and superimposed on each other and, by a second operation which is the deployment, inflation and stiffening by separate pressurization of each beam one after the other in deflating sealed temporary closure means which open the internal volume confined with the pressurized fluid supply duct, the deployment of the arch being maintained by the inflation of these sealed means to close the internal confined volume.
  • Fig. 1 schematically shows an embodiment of several inflatable beams A, B, C ... which are assembled together, side by side, to form the vault according to the invention.
  • each beam A, B, C ... is constituted by four longitudinal panels assembled at the corners to form a beam with box of which two opposite panels 1 and 2 are the soles and constitute one of the lobes of the interior wall and one of the lobes of the poly-lobed exterior wall of the vault.
  • the two other intermediate panels 3 and 4 of each of these beams are the cores of the box beam and constitute bracing ribs which transmit and balance the lobing tensions of said soles resulting from the effect of the internal pressure of the confined volume 5.
  • These core panels 3 and 4 play another fundamental role in this assembly of beams: they seal the vault between two consecutive beams. Indeed, the internal pressure of the confined volume 5 in each of the beams strongly applies one against the other, and over their entire surface, the core panels 3 and 4 which have been brought into contact by the assembly of these contiguous beams.
  • Each beam A, B, C ... can also be constituted by two longitudinal panels whose surfaces are sequential along two longitudinal edges, or by three longitudinal panels whose surfaces are sequential along three longitudinal edges.
  • a series of flaps 6 respectively extend the panels 1 and 4 along their longitudinal edge. Slightly spaced from each other, these flaps 6 are, for example, separated by notches 7 and advantageously they correspond vis-à-vis, not only from one panel to another of the same beam, as shown in Fig. 2, but also from one panel to another of two contiguous beams.
  • Each of these flaps is equipped at its free end with a rope such as 8 made for example using a cylindrical rod 9 of flexible material, trapped in a hem 10 formed by folding and gluing on itself the fabric of the flap.
  • a lobed membrane such as 11.
  • Each membrane 11 is fixed by gluing or welding by covering inside panels 1, 2, 3 and 4 which it connects to the right of the longitudinal junction surfaces and constitutes a cusp of the perimeter of the envelope of the corresponding beam.
  • This arrangement is particularly advantageous because it allows easy assembly of the consecutive elementary panels of the beam until the complete closure of the confinement-confinement of the volume 5.
  • all the bonding surfaces which must be pressed strongly using a gooseneck press, in particular a heated press, are accessible from the outside of the beam casing.
  • the membrane 11 and the series of flaps 6 are part of a single piece.
  • This arrangement is not compulsory, but it is also particularly advantageous from the point of view of simplicity of manufacture.
  • the flexible strip formed by the membrane 11 and the flaps 6 bordered by the ropes 8 can be a semi-finished product, made in great length, without any precaution as to the precision of its width.
  • the precision work which will give its good dimensions to the arch, will only consist in correctly positioning the ropes 8 by compared to the edges of panels 1, 2, 3 and 4 of the beams.
  • the width of the membrane 11 does not matter because, when the volume 5 is pressurized, it will be applied in the position 11a against the panels 1 and 4 and will not be subject to any tensile stress due to the fact that we have taken the precaution that its width developed from one to the other of the junctions is clearly greater than the corresponding distance measured on the flaps which extend these panels.
  • Fig.3 shows a portion of two contiguous beams such as A and B in Fig. 1, close to its edge where the surfaces of the panels 1 and 4 of the beam A and 1 and 3 of the beam B are sequent.
  • the four flaps 6 which correspond opposite are joined by a profile 12 which comprises three longitudinal grooves 13 in the form of a dovetail, the first of which 13a traps the headline 8 of the flap 6 of panel 1 of the beam A, the second 13b traps the headline 8 of the flap 6 of panel 1 of the beam B, and the third 13c traps both the ropes 8 of the flaps 6 extending the two cores 3 and 4 which are therefore arranged one against the other.
  • This arrangement is particularly advantageous because, on the one hand, it allows easy assembly of the beams together using a plurality of profiles 12 of short length, at most equal to that of the flaps 6 and which are simply threaded one after the other simultaneously around the four ropes 8 without difficulty, precisely because of their short length. On the other hand, and despite this subdivision, the tension forces transmitted to the link by the four panels which it joins are evenly distributed over the entire length of this link.
  • Fig.4 shows a variant of the assembly profile of two contiguous beams such as beams A and B.
  • the profile 14 also includes three longitudinal grooves 14a, 14b, 14c which trap the slings 8 of the panels of each beam. Each groove is formed by two sequential orifices 15a and 15b of different diameters.
  • Each orifice 15b has a diameter greater than the diameter of the headline 8, thus allowing the introduction of the profile 14 on said rope, and each orifice 15a has a diameter slightly less than the diameter of the headline, in order to block the rope in the profile.
  • the ropes 8 of the cores 3 and 4 are formed by ropes having a section corresponding to half the section of the ropes of the panels 1, so that, when they are pressed one against the other, they have a cross section equal to the cross section of the other ropes.
  • This arrangement allows to have a profile with identical grooves, which avoids the introduction of the profile on the slings in a determined direction.
  • Figures 5, 6 and 7 show the assembly of a vault according to the invention drawn in these three views.
  • this vault comprises two advantageously symmetrical parts P1 and P2 each composed of a plurality of inflatable beams A, B, C ... assembled together as indicated above.
  • This vault can, for example, cover a football field and it is interesting that it can, in good weather, be completely open, these two assemblies of beams being stored flat as shown in Fig. 7, all the beams deflated being superimposed on each other.
  • the ends 21 of the arched beams are equipped with support fittings such as 22 which are movable parts guided by guide means 23 whose curvature determines the path of deployment of each of the beams A, B, C ... between the position it occupies when it is deflated and stored flat and that it occupies when it is inflated and erected among the other beams.
  • support fittings such as 22 which are movable parts guided by guide means 23 whose curvature determines the path of deployment of each of the beams A, B, C ... between the position it occupies when it is deflated and stored flat and that it occupies when it is inflated and erected among the other beams.
  • FIGS. 8 and 9 show more precisely one of the support and retaining fittings 22 common to two beams, for example A and B.
  • This fitting sandwiched between the cores 3 and 4 of said beams on which it is fixed, for example using bolted flanges 24a, 24b and 25a, 25b extends below these beams to an axle 27 which carries at least two rollers 28 cooperating with the guide rails 29 which constitute a path rolling.
  • the fitting 22 forms, in association with the flanges 24a and 24b and the rods 26a and 26b, a border of the orifices 30 as formed in the cores 3 and 4 of the beams such as A and B.
  • Fig.10 shows that the series of these orifices 30 formed in the pairs of two cores joined 3 and 4 of the beams A, B, C ... of the vault determines a fictitious conduit 31 of the volumes 5 confined by the envelopes of the beams inflatable A, B, C ...
  • the communication along an annular passage section between the volumes 5 and the conduit 31 can be temporarily and independently closed by each of the inflatable and flattenable annular bladders 32.
  • the bladders 32 are shown in the configuration where, inflated, they seal said communication and isolate the volumes 5 whether these are empty and flattened or inflated.
  • the bladder 32a is shown flattened, which opens the communication between the conduit 31 and the volume 5 and allows either inflation or deflation thereof.
  • a fan shown diagrammatically at 33 and connected to one end of the duct 31 constitutes the main source of pressurized fluid intended for inflating or deflating the vault.
  • a secondary source of pressurized fluid 34 can deliver a fluid at a pressure higher than that of the main source and which advantageously is connected via flexible pipes such as 35, multi-way valves such as 36 and internal conduits such as 37, to each of the inflatable bladders 32.
  • the means of temporary confinement of the supply conduit 31 can be constituted by a pair of two inflatable and flattenable annular bladders equipping each beam.
  • the means of temporary confinement of the supply conduit 31 are formed, inside each inflatable beam A, B, C ... between the orifices 30, for part of a flexible sleeve 40 waterproof and flattenable and, for another part, by an inflatable and flattenable seal 41 opening or closing the annular communication 42 between the conduit 31 and the volume 5 confined by the envelope of each beam.
  • the flexible sleeve 40 has, in the deployed position, substantially the shape of the half-part of a toroidal surface located closest to the center of the torus, the supply conduit 31 being located on the convex side of the sleeve and the volume 5 confined in the envelope of each beam on the concave side of said sleeve.
  • This particular shape of the conduit makes it possible to maintain the stability of its wall stretched by the pressure both if this pressure is higher in the volume 5 than in the conduit 31, than if it is higher in the conduit 31 than in the volume 5 .
  • a secondary source of pressurized fluid (not shown) delivers a fluid at a pressure higher than that of the main source to each of the inflatable seals 41.
  • the vault is composed of two parts P1 and P2 which are each assemblies of flexible and inflatable elementary beams A, B, C ... which are stored deflated on their bases 45a and 45b and are deployed by inflation towards each other while coming to bear at the end of the erection stroke against the walls 46a and 46b of a rigid and permanent central arch 46.
  • This arch 46 is equipped with means of guiding and centering, such as for example conical canopies 47a and 47b inside which the toroidal walls of the extreme inflatable beams come to shoulder.
  • the arch is also equipped with a plurality of hooking means (not shown) such as for example hooks which automatically hook and release the extreme inflatable beams.
  • This arrangement is particularly advantageous from the point of view of public safety in the case where the vault according to the invention is intended to cover, for example, an auditorium. Indeed, which besides is very improbable because of the subdivision of the vault in multiple waterproof beams and separated from each other, if we were in the extreme situation where all the beams were torn and deflated, the 'all the walls would nevertheless remain attached to the rigid beam and would not risk falling on the public to hinder the evacuation of the room.
  • the vault is moored to come to a standstill relative to the ground, by partial filling of a beam advantageously situated in the lower part of the vault, for example with a ballasting liquid which may simply be water.
  • Fig.13 illustrates another embodiment of the mooring on the ground of a vault according to the invention which uses means similar to those allowing the assembly of two contiguous beams between them.
  • the core 2 of the beam which rests on the ground symbolized by the line 20, is equipped with flaps 50a and 50b each provided with a headline 51a and 51b, and the flanges 3 and 4 of said beam are also equipped with flaps 52a and 52b each provided with a line 53a and 53b.
  • the watertightness of these flaps is ensured by membranes 54a and 54b.
  • the mooring of the beam is carried out using a series of profiles 55 each having two grooves 55a and 55b.
  • Fig.14 shows a view of a variant of the assembly of a vault according to the invention.
  • the profile of the deployment path 60 like the profile of the sections 61 of the arch parallel to said path, are curves in basket handles composed of at least two arcs of a circle R1, R2 and R3, R4 of radii of different curvature connected to each other.
  • the vault is composed box girders which have identical core panels 3 and 4 and whose width of their upper sole panels 1a and 1b and the respective width for the same section of their lower sole panels 2a and 2b are in a different ratio depending on whether each of these beams is located in an area of said profile corresponding to one or the other of the radii of curvature R3 or R4. This arrangement makes it possible to make arches that are less than half their width.
  • the vault is associated and connected to at least one prefabricated gravity structure 62 and composed of identical rigid modular elements in the shape of U 63 arranged side by side to form at least one substantially circular gallery 64, each modular element of which occupies one of the sectors S (FIGS. 15 and 16).
  • the modular U-shaped elements can be made of reinforced concrete.
  • each deployment path can also be constituted by a rigid arch 70 in the form of a gutter comprising in particular 2 bent tubes 71a and 71b located in parallel planes and interconnected by curved spacer plates 73.
  • Each of the end support fittings 74 of the inflatable beams A, B, C ... is extended by two pads 72a and 72b articulated on said fittings and in the form of hooks cooperating with the tubes 71a and 71b which they partially surround and over which they slide in order to guide the deployment of said inflatable beams of the roof, as well as their support and their retention when they are subjected to the effect of the wind in the closed vault position.
  • This deployment path is also associated with an inflatable and flattenable cushion 75 resting on the curved spacer plate 73 extending over at least part of the length of the arch 70, between the guide tubes 71a and 71b.
  • the cushion 75 is deflated during the deployment or retraction maneuver of the vault and inflated when the deployment is completed, on the one hand, obscuring the space between the arch and the ends of the deployed beams in order to achieve the weathertightness of said vault and, on the other hand, exerting a thrust which eliminates the operating clearance necessary for the sliding of the pads on the guide tubes in order to avoid the flapping of the vault under the effect of gusts of wind.
  • Fig.20 shows a vault according to the invention which is used as a means of protection against the weather and camouflage cover of mobile equipment, such as for example an aircraft which must be able to enter and exit possibly by its own means.
  • the vault P has one or two parts which can be retracted, while another part can remain in place and support the retracted parts. These parts are retracted by deflation and depression of the beams which compose them. We can thus gain access to both ends of the roof, which allows for example an aircraft to exit on its own using the thrust of its reactor.
  • All the inflatable beams which compose it, whether integrated in the part which remains inflated or in the retractable parts, are connected together by their common supply conduits 30a and 30b, and are connected to a generator of pressurized fluid and for thermal conditioning of this fluid 80 via the conduits 81 and 82.
  • this generator is a fluid refrigeration unit which feeds the exchanger that constitutes all the beams, ensuring advantageously a closed circuit flow, which travels successively through the conduit 81, the conduit 30b, the beams forming multiple conduits which are all connected to the conduit 30b as to the conduit 30a which collects the flow rates of all the beams and finally the return conduit 82.
  • This arrangement makes it possible to surround the aircraft with a cold zone in order to erase the thermal signature of its reactor after a flight or a fixed point and from the e make invisible to detection means sensitive to infrared radiation.
  • Fig. 21 shows a vault according to the invention, composed, on the one hand, of a rigid part 90 which is an arch vault comprising for example three half-arches 90a, 90b, 90c arranged at 120 ° and joined at their common top 91 and, on the other hand, three advantageously identical inflatable parts 92a, 92b, 92c, which each result from the assembly of the inflatable beams described above.
  • This rigid arch advantageously rests on the ground on three support points 93a, 93b and 93c.
  • All these beams can be assembled together, while they are deflated and superimposed on each other at ground level by assembly means described above and their deployment is ensured by successive inflation of the beams.
  • the spaces between the guide tracks and the ground can advantageously be used as access zones inside the vault.
  • the means for supplying pressurized fluid can be constituted by an axial fan used to inflate the beams A, B, C ..., deflate them, put them in depression or maintain them in depression, in reversing its direction of rotation.
  • the means for supplying pressurized fluid can also be constituted by at least two air generators operating simultaneously and each connected to one of the supply conduits located at the two ends of the beams A, B, C ..
  • One of these two generators blows pressurized air to inflate and deploy part of said beams, while the other generator sucks the air contained in the beams of another part of the arch to maintain, by the depression thus created, the walls thereof folded and pressed against each other.
  • the longitudinal panels of the flexible envelope of the inflatable beams A, B, C ... can be produced from a grid or net of slightly spaced textile cables, of the order of 0.2 to 2 cm, and adherents to at least one sheet composed of at least one layer of plastic material at least one of which is impermeable to gas and at least one of which is heat-sealable. This sheet seals by filling the space left between the cables.
  • the advantages of the present invention result essentially from the possibility that it offers of producing very large arches, composed of a plurality of constituent elements which are easy to manufacture, easy to transport and assemble on site and which can be erected or retracted very quickly.
  • the inflatable vault according to the present invention applies to the covering of stadiums, swimming pools, tennis courts, sports halls, restaurants, performance halls, exhibition halls or shops, various facilities, leisure parks, congress halls or large storage sheds.
