Abstract The invention relates to a prefabricated construction element (1) having a permanent form, such as a longitudinal beam or a panel, consisting of two parallel plates that are formed, through molding and spaced apart from each other, from a hydraulic mixture such as concrete and from a built-in metal reinforcement, said plates being separated by an insulating block and connected together by transverse spacers (not shown), characterized in that said construction element (1) comprises consecutive prepositioning and bottom (6, 7) and/or top (8, 9) linking means, said bottom means (6, 7) consisting of a metal male connector (6) secured to the metal reinforcement of a first element (1) and arranged at the end of the bottom portion of said first element, and a metal female connector (7) secured to said metal reinforcement of a consecutive second element and arranged at the end of the bottom portion of said second element, the relative positioning of the male connector (6) and female connector (7) being such that said connectors can be connected together when the two consecutive elements (1) are assembled. ## Claims ### Claim 1 A construction system comprising at least two prefabricated construction elements each having a panel, the panels abutting each other along vertical faces, wherein each prefabricated element includes permanent formwork comprising two parallel plates at a distance from each other, each of the plates being in a solidified hydraulic mixture and including a built-in metal reinforcement, an insulating block separating the two plates, and transverse spacers interconnecting them, said construction system having prepositioning and connecting means to allow connection of two consecutive elements, formed by a male metal connector secured to the metal reinforcement of a first element, and by a female metal connector secured to the metal reinforcement of a second consecutive element, wherein the male connector includes a hook protruding in the direction of the female connector and the female connector forms a housing defined by first and second side walls perpendicularly stemming from a vertical face of a corner angle portion, delimiting a bottom corresponding transverse reservation, at an end of said second element, said first and second side walls being closed at their free ends by a third front wall perpendicularly stemming from a horizontal face of said corner angle, the hook cooperating with said third front wall to assemble the elements, the side walls of the housing of the female connector extending through fins extending away freely from each other to form a V, so as to allow guidance and facilitate the introduction of the hook in said housing. ### Claim 2 (depends on 1) The construction element according to claim 1, wherein the corner angle from which stems the housing of the female connector, includes, on its opposite faces, fins extending perpendicularly to the sidewalls of said housing, so as to form anchoring points in the plates forming said construction element. ### Claim 3 (depends on 2) The construction element according to claim 2, wherein the anchoring fins of the corner angle of the female connector are provided with holes for letting through metal profiles for reinforcement of the anchoring. ### Claim 4 (depends on 1) The construction element according to claim 1, wherein the male connector forms a hook comprising a flat part, perpendicularly stemming from a corner angle portion added in a bottom corresponding transverse reservation, at the end of said element. ### Claim 5 (depends on 4) The construction element according to claim 4, wherein the corner angle from which stems the hook of the male connector, includes, on its opposite faces, fins extending perpendicularly to the side walls of the housing and parallel to the hook, so as to form anchoring points in the plates forming said construction element. ### Claim 6 (depends on 5) The construction element according to claim 5, wherein the anchoring fins of the corner angle of the male connector are provided with holes for letting through metal profiles for reinforcement of the anchoring. ### Claim 7 (depends on 4) The construction element according to claim 4, wherein the horizontal wall of the corner angle from which stems the male connector, includes a vertical threaded bushing, directed downwards, with which a screw cooperates by screwing, thereby allowing adjustment of the level and slope of the element relatively to the ground. ### Claim 8 (depends on 4) The construction element according to claim 4, wherein the bottom horizontal face of the corner angle supporting the hook of the male connector extends on either side of said hook, with lugs extending parallel and capable of cooperating during assembly with the underside of the horizontal face of the corner angle of the female connector, on either side of its housing, so as to balance the whole during assembly. ### Claim 9 (depends on 1) The construction element according to claim 1, further including connecting means at a top portion of the construction element formed by a female metal fitting part, with the shape of an omega or dovetail, extending with side wings cooperating with the end of the element and the dovetail or omega cooperating with a corresponding housing, made at the end of said element, said fitting part being reproduced and placed opposite, on a consecutive element to be joined at a first end and by a male connecting member, forming a double omega or a double dovetail, capable of simultaneously cooperating with both fitting parts of two consecutive elements at a second end. ### Claim 10 (depends on 9) The construction element according to claim 9, wherein the fitting parts include fins forming anchoring points on the plates and are provided with holes for letting through metal profiles for reinforcement of the anchoring.
