- a permanent concrete formwork for the manufacture of a metal / concrete composite structure comprises two walls 20 and 30 which are located opposite one another and which are parallel between them.
- the two walls 20 and 30 are spaced apart so that the formwork 10 comprises an internal volume 40 delimited by said two walls 20 and 30.
- the two walls 20 and 30 each comprise at least one metal plate 50.
- the walls 20 and 30 each comprise two metal plates 50 arranged one after the other in the same plan.
- the metal plates 50 may be for example steel.
- the formwork 10 comprises spacers 60.
- the spacers 60 pass right through said two walls 20 and 30 projecting from each side of the formwork 10.
- the spacers 60 are intended to be taken in the concrete once the concrete has been poured inside the volume 40 of the formwork 10.
- a plurality of spacers 60 is distributed over the entire surface of the walls 20 and 30 of the formwork 10, preferably in a regular manner.
- the spacers 60 make it possible to withstand the mechanical stresses of the formwork 10.
- the spacers 60 also make it possible to ensure that the spacing between the walls 20 and 30 is constant.
- each metal plate 50 is fixed to the metal plate 50 facing it by at least 3 spacers 60.
- a first spacer 60 is located at a first end of the metal plate 50
- a second spacer 60 is located at a second end of said metal plate 50 opposite the first end
- a third spacer 60 is located in a central zone of said metal plate 50.
- the spacers 60 are formed of a threaded bar at its two ends which are fixed to the walls 20 and 30 by bolting.
- the bolts that fix the spacers 60 to the walls 20 and 30 of the formwork 10 may be formed by 2 nuts.
- the spacers 60 project from the formwork 10 makes it possible to know where the spacers 10 are located in the metal / concrete structure once the concrete has been poured inside the formwork 10 (as can be seen in FIGS. 6), thus making it easy to estimate the resistance to mechanical loads that the equipment can withstand when attached to the metal / concrete structure.
- the formwork also comprises bars 70 on each of the walls 20 and 30 and which project into the internal volume 40 of the formwork 10.
- the bars 70 are also called “studs" in the technical field of the manufacture of composite metal / concrete structure.
- the bars 70 comprise a first end which is fixed to the walls 20 or 30, for example by welding, and a second end directed towards the inside of the internal volume 40 of the formwork 10.
- the function of the bars 70 is to ensure good cohesion between the walls 20 and 30 and the concrete which is poured into the internal volume 40. Once the concrete has poured into the cured formwork, the bars 70 take up the shearing forces between the walls 20 and 30 and the concrete.
- the bars 70 preferably comprise a protuberance at their second end.
- the formwork 10 comprises an assembly bar 80 situated inside the internal volume 40 facing the connection between two metal plates 50 forming the walls 20 and 30.

- the assembly bar 80 serves to maintain the position in position. metal plates 50 forming the same wall 20 or 30. Indeed, when the concrete is poured inside the internal volume 40 and the latter has hardened, the presence of the assembly bar 80 can create a mechanical connection of the metal plates 50 forming the same wall 20 or 30.

- the assembly bar 80 can be fixed by a plastic insert to the bars 70, to the struts 60, or to the walls 20, 30.
- the assembly bar 80 may also be fixed by a wire, for example a wire, the bars 70, the struts 60, or the walls 20,30 to hold it in position.
- the assembly bar 80 makes it possible to assemble the metal plates 50 without welding.
- the fact of using the assembly bar 80 also makes it possible to reduce the positioning stresses of the metal plates 50, a slight offset being allowed with said assembly bar 80.
- the bars 70 located at the periphery of the metal plate 50 preferably have a diameter greater than the diameter of the bars 70 situated in the central part of said metal plate 50.
- Such a variant is advantageous because when the assembly bar 80 rests on the bars 70 located at the periphery of the metal plate 50, the mechanical forces taken up by the assembly bar 80 are transferred to the bars 70, thus subjecting the bars 70 to bending and shear stresses.
- the number per unit area of bars 70 located at the periphery of the metal plate 50 is greater than the number per unit area of bars located in the central portion of said metal plate 50, so as to better take up the efforts of pulling of the assembly bar 80.
- the formwork 10 may comprise a sealing plate 90 which has the function of to prevent concrete from flowing out of the internal volume 40 formwork 10 by the interstices that may exist between the metal plates 50 which form the same wall 20 or 30.
- the sealing plate 90 is fixed to the ends of two adjacent metal plates 50 which form the same wall 20 or 30.
- the sealing plate 90 covers the end of the metal plates 50 over the entire height H of said metal plates 50.
- the sealing plate 90 may be attached to the ends of the struts 60 which project out of the walls 20 and 30, for example by bolting.
- the sealing plate 90 may be for example a wooden plate.
- the sealing plate 90 is removable, it is removed once the concrete which has been poured inside the internal cavity 40 has hardened.
- the formwork 10 may also include an alignment spar 91 whose function is to ensure that the metal plates 50 forming the same walls 20 or 30 are in the same plane.
- the formwork 10 advantageously comprises at least one alignment spar 91 on each of its walls 20 and 30.
- the alignment spar 91 is attached to two adjacent metal plates 50 which form the same wall 20 or 30 outside the internal volume 40.
- the alignment spar 91 is removably attached, it is removed once the concrete that has flowed inside the internal cavity 40 has hardened.
- the alignment spar 91 is attached to the spacers 60 which project out of the walls 20 and 30, for example by bolting.
- the alignment spar 91 covers at least half the length L of each metal plate 50 on which said alignment spar 91 is attached. Such size of alignment spar 91 makes it possible to ensure better alignment of the two adjacent metal plates 50 in the same plane.
- the variant illustrated in FIG. 4 comprises both sealing plates 90 and alignment spars 91, however the formwork 10 may comprise only sealing plates 90, or include only alignment rails 91.
- FIGS. 5 and 6 show a composite metal / concrete structure 100 which has been manufactured with the permanent concrete formwork according to the invention.
- the structure 100 metal / concrete comprises a concrete layer B which is surrounded by the walls 20 and 30 of the formwork 10.
