Abstract: The invention relates to plate that comprises an upper strip (1), a lower strip (2), both of which are flat, and a multidirectionally folded, curved or undulate intermediate structure (3) arranged between the upper strip (1) and the lower strip (2), and which is joined to the upper (1) and lower (2) strips at contact zones or connection points (4) and (5), intermittently located and distributed, such that it defines at least two chambers, channels or hollow spaces, interstitial (6) and (7) and continuous, which extend throughout the plate in at least two different directions. This way, a lightweight plate is obtained that is structurally, acoustically and thermally resistant, easy to systematically manufacture or mount and can be efficiently used as an integral system for constructing slabs and similar, since the inner holes can also be used as integrated accessible channels for installations.
