According to another embodiment, it can be achieved a family of daggers 15 having rods 18 of different lengths thus making it possible to produce walls of different thicknesses.
- the rod 18 is provided with a bearing abutment 20 placed near the upstream end I8 2 to come into contact with the outer face 4 2 of the insulating panel 4.
- the bearing abutment 20 is made under the shape of a disk extending transversely with respect to the rod 18. This abutment 20 is remote from the upstream end I8 2 of the rod 18 at a distance corresponding to the thickness of the outer wall 3. The adjustment of the length of the rod 18 from the upstream end I8 2 makes it possible to adapt to the thickness of the outer wall 3.
- the width between the upstream end I82 of the rod 18 and the outer surface 4 2 of insulating panel 4 can be adjusted using one or more washers strung on the rod 18 from the downstream end I8 1 up to come into contact on the abutment 20.
- the establishment of these washers allows to move the support for the insulating panel 4 relative to the upstream end I82.

- the latch 16 also includes a hook 26 adapted to hook with the internal structure reinforcement 9.
- the hook 26 thus extends radially from the distal end of the tubular sleeve 23.
- the hook 26 is in the form of a wafer of substantially rectangular shape, of limited angular width of the order of ten degrees.
- the latch 16 and the dagger 15 comprises assembly means for fixing the latch 16 on the rod 18 in a fixed position along the rod 18 so that the abutment stop 20 and the abutment 24 are respectively in position. support on the faces 4i, 4 2 of the insulating panel 4. In the embodiment illustrated in FIGS.
- the assembly means comprise at least one lug 28 carried by the rod 18 and intended to cooperate with at least one complementary housing 29 arranged on the tubular sleeve 23.

- the stem 18 is provided with a series of lugs 28. distributed along the length of the rod 18 to correspond to various conventional thicknesses of the insulating panel 4. These lugs 28 are distributed equally angularly on the periphery of the rod 18 so as to be able to each enter a corresponding groove 30 provided on the latch 16.
- the latch 16 thus has as many grooves 30 and housings 29 as lugs 28, these grooves 30 being angularly offset from each other by a value equal to the angular offset presented by the lugs on the rod 18.
- This dagger 15 and this latch 16 allow to be used for various thicknesses of the insulating panel 4 by choosing the cooperation of the appropriate pin with its corresponding housing.

- these irreversibility means 31 are made by deformable fingers resiliently adapted to be deformed by the lugs 28 during the rotational movement of the lugs leading them into the housings 29. When the deformable fingers 31 are no longer stressed by the lugs 28 these fingers 31 return to their initial position ensuring the locking of the lugs 28 inside the housings 29, preventing their rotation in a direction leading to their exit from the housings 29.

- the tubular sleeve 23 of the latch 16 is threaded onto the rod 18 from its downstream end 18i.
- the latch 16 is translated so that the abutment 24 comes into abutment with the inner face 4i of the insulating panel 4. During this translation, the latch 16 is oriented angularly so that a lug 28 slides in a complementary groove 30 .
- the latch 16 is angularly rotated relative to the rod 18 so as to bring the lug 28 into the complementary housing 29 to allow locking of the latch 16 in a fixed position on the rod 18 (FIG 5)
- the lug 28 deforms the fingers 31 before entering the housing 29. At the end of this rotational movement, the lug 28 is blocked by the fingers 31 prohibiting it from rotating in the opposite direction.
- each wall 6, 7 has through holes 6i, 7i respectively for the passage of a clamping rod 41.
- the process according to the invention consists, as illustrated in FIG. 9, to set up the reinforcement of internal structure 9 with respect to the inner ring 6.
- the establishment of this reinforcement internal structure 9 is not described more precisely because it is well known to those skilled in the art.
- the reservation mannequins for the openings or the frames to bancher are positioned on the internal jackethe before the establishment of the reinforcement of internal structure 9.

- the method according to the invention consists in setting up the outer wall 7 to bear on the upstream end 332 of the spacer During this operation, the clamping rod 41 is engaged inside a through-hole 7i provided in the outer wall 7 (FIG 2). In this position, the clamping rod 41 completely traverses the panels 6, 7 and the insulation panel 4 extending on either side of the panels 6, 7. The clamping rod 41 then serves for mounting clamping members such as nuts 42 to ensure the locking in position of the panels 6, 7 between them. It should be noted that during this operation, the tightening of the nuts 42 ensures a localized deformation of the downstream ends 33i and upstream 332 of the tubular spacer 33 so as to ensure a seal between this tubular spacer 33 and the panels 6 , 7.
- the concreting operation intended to ensure the simultaneous or substantially simultaneous injection of the concrete between the insulating panel 4 and the panels 6, 7 to simultaneously realize the internal wall 6 and external 7.

- the tubular spacers 33 are provided with removable rings at their ends, these removable rings are removed so that the tubular spacers that remain in place are no longer flush with the outer faces of the walls 2, 3.
- the wall 1 made thus incorporates the assembly devices 14 and the positioning systems 13 which are mounted independently of one another and thus provide in combination a mechanical retention of the outer wall 3 with respect to the inner wall 2.
