A tooling for manufacturing a wall with two concrete walls, between which at least one insulation panel is trapped includes at least one system for positioning the insulation panel composed, on one hand of a dagger having a rod provided with a bearing stop and, on the other hand, of a lock provided with a counter-stop. The lock has at least two notches for receiving a first reinforcement, arranged locally on the circumference of the positioning system, extending set back from a first end of the rod, delimited on either side by retaining stops spaced apart so as to maintain in position the first reinforcement, and defines a housing with a profile converging in the opposite direction to their opening, and arranged according to the length of the positioning system to be able to adjust the position of the first reinforcement according to the length of the positioning system.
1- A tooling for manufacturing a wall (1) with two concrete walls (2, 3) between which at least one insulation panel (4) is trapped, this tooling including at least one system for positioning (8) the insulation panel (4) composed, on the one hand of a dagger (10) having a rod (12) provided with a bearing stop (13) and, on the other hand of a lock (11) provided with a counter-stop (16), the rod (12) having a first end (121) intended to be in contact with a first form panel (6) and a second end (122) intended to be in contact with a second form panel (7), so that the distance between the first and the second end is equal to the thickness of the wall (1), characterized in that the lock (11) is provided with at least two notches (17) for receiving a first reinforcement (51), arranged locally on the circumference of the positioning system, extending set back from the first end (121) of the rod (12), delimited on either side by retaining stops (18) spaced apart so as to maintain in position the first reinforcement (51), defining a housing with a profile converging in the opposite direction to their opening, and arranged according to the length of the positioning system (8) so as to be able to adjust the position of the first reinforcement (51) according to the length of the positioning system (8).
2- The tooling according to claim 1, characterized in that the retaining stops (18) include a locking detent (20) at the opening of the notches (17).
3- The tooling according to claim 1 or 2, characterized in that the positioning system (8) comprises a first hook (14) extending radially set back from the first end (121) of the rod (12), and delimiting a first retaining stop (181).
4- The tooling according to claim 1, characterized in that the positioning system (8) comprises a second hook (21), angularly orientable and extending set back from the second end (122) of the rod (12), in order to maintain in position a second reinforcement (52).
5- The tooling according to claim 1, characterized in that the distance between the bearing stop (13) and the counter-stop (16), possibly in the presence of one or more compensating washers, is equal to thickness of the insulator (4).
6- The tooling according to claim 1, characterized in that it includes devices for assembling (9) the form panels (6, 7) together, each including a tubular spacer (26) inside which a tightening rod (32) provided at each end with a tightening member (33) passes.
7- The tooling according to claim 1, characterized in that the dagger (10) includes assembly means (22, 23, 24) between the lock (11) and the dagger (10).
8- The tooling according to claim 7, characterized in that the assembly means include at least one lug (22) arranged on the rod (12) of the dagger and cooperating with a housing (23) arranged on the lock (11) after rotation thereof.
9- The tooling according to claim 7, characterized in that the assembly means (22, 23, 24) between the lock (11) and the dagger (10) are of the irreversible or repositionable type.
10- A method for manufacturing a wall (1) with two concrete walls (2, 3), between which at least one insulation panel (4) is trapped, the two walls (2, 3) being manufactured simultaneously or substantially simultaneously by pouring concrete between the insulation panel (4) and a first form panel (6) on the one hand, and between the insulation panel (4) and a second form panel (7) on the other hand, the form panels (6, 7) being disposed on either side of the insulation panel (4), a first reinforcement (51) being placed on the side of the inner face of the first form panel (6), the insulation panel (4) being held between the two form panels (6, 7), before pouring the concrete, using positioning systems (8) passing through the insulation panel (4) and bearing on the inner faces of the form panels (6, 7), the positioning system (8) being composed, on the one hand, of a dagger (10) having a rod (12) provided with a bearing stop (13) and, on the other, of a lock (11) provided with a counter-stop (16), the method being characterized by:
11- The method according to claim 10, characterized in that it comprises placing a second reinforcement (52) on the side of the inner face of the second form panel (7), with possible rotation for the passage of at least a second hook (21) angularly orientable and extending set back from a second end (122) of the rod (12) and their assembly with said second reinforcement (52).
12- The method according to claim 10, characterized in that it consists in placing on each insulation panel (4), the positioning systems (8) by threading the rod (12) of a dagger (10) up to a bearing stop (13), a lock (11) provided with at least two notches (17) being assembled on the rod (12) protruding from the insulation panel (4), when a counter-stop (16) carried by the lock (11) bears against the insulation panel (4), possibly in the presence of one or more compensating washers.
13- The method according to claim 10, characterized in that the two form panels (6, 7) are maintained in position using assembly devices (9) by placing, for each assembly device (9), before positioning the second form panel (7), a tubular spacer (26) passing through the insulation panel (4) and after positioning the second form panel (7), sealingly bearing on the inner faces of the form panels (6, 7), each tubular spacer (26) being traversed by a tightening rod (32) extending outside the form panels to receive at each end a tightening member (33).
