Resistant modular hollowed-out plate for manufacturing slabs

A resistant modular hollowed-out plate for manufacturing slabs, which comprises:

• a flat upper strip;
• a flat lower strip;
• a multidirectionally folded, curved or undulate intermediate structure arranged between the upper strip and the lower strip, and which is joined to the upper and lower strips at contact zones or connection points and, intermittently located and distributed, such that it defines at least two chambers, channels or hollowed-out spaces, interstitial and continuous, which extend throughout the plate in at least two different directions
• wherein;
• the intermediate structure comprises joining modules;
• the upper strip and/or lower strip have perforations;
• the joining modules of the intermediate structure are joined to the upper and lower strips by one or a combination of joining means, consisting of metal plates or connectors, angular profiles, screws, male-female coupling and joining by means of adhesives, and wherein the upper strip and/or lower strip have linear reinforcements contained on a surface thereof wherein
• the joining modules are separate pieces of truncated pyramids with a polygonal base, the truncated pyramids are made up of a series of the separate pieces corresponding to faces of the truncated pyramids, the separate pieces are joined to one another and end pieces with a geometry which coinciding with ends of the truncated pyramids, the end pieces being joined to the upper strip and to the lower strip and wherein the hollowed-out plate is a slab.
