Tensioning installation for the frameworks of pre-tensioned architectural elements designed for the two-way pre-tensioning of concrete or mortar plates, or the like, comprising a moulding assembly made up of a flat moulding plate (3) delimited on the perimeter by adjustably positioning side walls (4). The assembly rests on an oversized support platform (1) on which the moulding assembly is surrounded by a perimeter area (10) of support platform (1) proper, in which perimeter area (10) hydraulic tensioning devices (7) are provided, which are integral to support platform (1) and are arranged in juxtaposition forming opposite facing pairs according to rectilinear alignments forming a grid. Said hydraulic tensioning devices (7) are all connected together serially forming a hydraulic circuit (8) which, in turn, is connected to a hydraulic pressure connection point (9). |
