Method for the production of a reflecting mirror in a single piece suitable for a concentrating solar plant, of the Fresnel type, said mirror being provided with only one curvature axis, comprising the steps of: a. preparing a single plate of deformable material that is at least elastically deformable, so that said plate is provided with at least one optically reflective surface; b. preparing a die having a shape opposite to that of the mirror to be produced for a Fresnel solar plant; c. prearranging means for defining a hollow with said single plate; said single plate partially delimiting said hollow, and said means being provided with at least one through hole of fluidic communication; d. coupling, substantially by sealing, said means for defining a hollow to said single plate, said plate being in its own substantially not - deformed condition; e. joining said single plate of deformable material in a substantially not - deformed condition, coupled with said means for defining a hollow, to said die, with said at least one optically reflective surface partially engaging said die; f. injecting into said hollow, through said at least one through hole, at least one plastic filling material in a fluid, or fluidized, state, in order to move said at least one reflective surface from a position partially engaged with said die to a position totally engaged with said at least one reflective surface against said die; said at least one plastic filling material being adhesive, at least when solidified, to said single plate; g. solidifying said at least one plastic filling material; h. drawing out from said die said single plate permanently deformed as a mirror suitable for a Fresnel solar plant. |
