<p>The invention relates to a system for the quick coupling of shaped plates (1, 2, 3) of the type used in the construction of a torsion box of a solar power facility that harnesses heat. Each shaped plate includes flanges (4, 5) along the longitudinal edges thereof, both of which are provided with perforations. One of the aforementioned flanges (5) includes elastic tabs (8) formed at pre-determined positions along the length thereof, with a thickened portion (9) being provided next to the end of the inner surface thereof, while the other flange (4) includes pairs of through-holes (6, 7) aligned with and facing the elastic tabs (8), such that a tab can be passed through one of the holes and the thickened portion (9) can be inserted into the other opening when the shaped plates are coupled.</p> |
