Abstract: The support system to manufacture metal reinforcements for concrete formed of longitudinal continuous bars assembled by transverse frames, comprises first and second parallel support arms placed in a same horizontal plane, and a carrying structure. The first and second parallel support arms are mounted on the carrying structure. The first parallel support arms (3) are associated with controllable units (5, 6, 7, 8), which allow simultaneous vertical movement to constitute a first vertically moveable horizontal support plane for the longitudinal continuous bars. The support system to manufacture metal reinforcements for concrete formed of longitudinal continuous bars assembled by transverse frames, comprises first and second parallel support arms placed in a same horizontal plane, and a carrying structure. The first and second parallel support arms are mounted on the carrying structure. The first parallel support arms (3) are associated with controllable units (5, 6, 7, 8), which allow simultaneous vertical movement to constitute a first vertically moveable horizontal support plane for the longitudinal continuous bars. The second parallel support arms (4) extend parallel to the first support arms to constitute a second horizontal support plane for the longitudinal continuous bars. The first and second horizontal support planes are partially superposed. The carrying structure is made up of vertical poles equipped with the first and second parallel support arms. The vertical poles are mounted on a rail structure (17), which extends according to a perpendicular direction to the first and second parallel support arms to support an adjustment of spacing between the vertical poles. Each vertical pole is equipped with a control pedal connected to a desired programmable automat. After selecting the poles to manufacture the desired reinforcement, the mounted and the synchronized descent of different movable support arms constitute the first support plane. The first parallel support arms are assembled on the carrying structure through a vertically movable cart, which is directed in displacement by means of a vertical endless screw positioned by a motorization. The second parallel support arms are assembled on the carrying structure with a fixed height of 0.70-1.30 m, and are rotatably mounted on the carrying structure around a vertical axis to allow retraction apart from a vertical obstruction of the first support plane. The carrying structure comprises two holdings for the additional removable support arms, which are parallel with the first and second support arms, and a measuring device. The removable support arms form a third support plane above the second support plane. The set of superimposed additional removable support arms confers a positioning choice for the third support plane or confers a possibility for creating several additional support planes. The measuring device allows to determine a height of the first support plane with respect to the second support plane.
