- the separation of the second element 51 by compared to the first element 50 provides access to the interior of line 3 for the maintenance of the means 41 for controlling the opening or closing of leaves 42.
- the second element 51 closes the part center of the first element 50 and ensures continuity of the external wall of the pipe 3 in the position of leaf 42 closed, as shown in FIG. 6.
- the adjoining walls 60 and 61 of the inflatable beams adjacent for example A and B are interconnected tightly around the corresponding pipe 3 using a plate 62 carrying the means of sliding constituted for example by a roller 63 or by a skate.
- Each roller 63 is intended to roll on the external wall of line 3 during deployment or folding the vault 1.
- Each plate 62 saves a free space 64 with the corresponding pipe 3 allowing intercommunication between the pressure vessels adjacent inflatable beams for example A and B.
- the free space 64 is either completely free, either permanently closed or temporarily closed for example after deployment of the arch.
- free space 64 is permanently sealed with a seal 65 fixed on plate 62 and rubbing against the external wall Line 3 during deployment or the retraction of the vault 1 so as to isolate the speakers pressurized adjacent inflatable beams by example A and B.
- free space 64 can be closed temporarily with a seal 66 inflatable and foldable.
- This seal 66 is fixed on the plate 62 inside which it is folded in the absence of pressurization and it deploys under the effect of its internal pressurization to apply from tightly on the external wall of the pipe 3.
- stowage watertight on each wall of adjacent inflatable beams for example A and B with the plates 62 is produced at using a clamp 67a and 67b held captive in an annular hem 68a and 68b formed by turning over the corresponding wall 60 and 61.
- the flanges 67a and 67b are fixed on the plate 62 by means of a plurality of bolts 69.

- the spacer 70 can wear a guide roller, not shown, on the corresponding line 3.
- the spacer 70 can be fixed at the same time on the adjacent plates 62 of the first beam A, the length of this spacer corresponding to the spacing of these plates 62 when the first beam A is inflated.
- the walls contiguous 60 and 61 of the inflatable beams adjacent by example A and B are linked together along the space which extends between the plates 62 and along the space between a plate 62 and the end (s) of the inflatable beams, by at least one hook-and-loop strap 71.
- This self-gripping strip 71 is composed of two parts 72 and 73 which can hang on one to the other or to drop from each other.

- the openings 5, 5a, 5c and 5d are closed by the corresponding leaves 42 and the orifice 5b is open.
- Fan 3 operates during inflation and the beam A which is opposite the open orifice 5b is inflated, then beam B is inflated because it is initially in communication with beam A and secondly, after a start of inflation in face of open port 5b.
- the opening 5b is closed and the opening 5c is open so as to inflate the beams C and D and and so on.
- the 5d port is first opened for deflate the N beam, then the M beam which communicates with beam N.

- membranes 75 and 76 move away from each other in the open position G by clearing the orifice 5 and by revealing one or more opening 79 in the portion (s) of the periphery of the membranes 75 and 76 where they are not interconnected.
- This pressurized fluid flow then passes from line 3 through port 5, then between membranes 75 and 76 through opening 79 and through orifices 82a and 82b to the inflatable beam A.
- the two membranes 75 and 76 are applied tightly against each other in the closing position F by flattening the opening (s) 79 and closing the orifice 5.
- the free space 64 is temporarily closable by a gasket 90 formed of three parts concentric.
- These three concentric parts are made up by a double annular membrane 91, a lip elastic 92 formed on one of the edges of the double membrane 91 and by at least one heel 93 for attachment to plate 62 and formed on the other edge of said double membrane 91.

- the double annular membrane 91 of the seal seal 90 is deformable between a first non- inflated (Fig. 13) sealing between two beams A, B, C ... M, N adjacent by elastic tightening of the lip 92 on line 3 and a second inflated state (Fig. 14) providing a passage between the two beams A, B, C ... M, N adjacent.
- the internal space 94 of the double membrane 91 is connected to the inflation means by a hose 96 and the pressure exerted by the elastic lip 92 on line 3, when the gasket 90 is in inflated position, is adjusted by a ring 97 secured of plate 62 and on which said seal is supported in deflated position.
- the position of the ring 97 by compared to plate 62 is adjustable. This setting can possibly obtained by shims of thickness 98.
- one of the membranes of the double membrane 91 is arranged between two stiffening flanges, 99a and 99b respectively, and the seal 90 is fixed on the plate 62, at the level of the heels 93, by a fastening member 100.
- the flange 99a disposed between the two membranes of the double membrane 91 has a conduit 101 opening into internal space 94 and connected to the means inflation, not shown.

- For the successive inflation of said beams A, B, C ... M, N on successively retract the corresponding gasket 90 by inflation, then deflate it when the corresponding beam has been inflated to the desired pressure.
- seals 90 which, in good condition deflated, apply, thanks to their shape and structure, on line 3.
- the line 3 of transport of pressurized fluid is arranged in the middle said beams A, B, C ... M, N.
