<p>System of modular construction for a covered structure of large cross-section built by assembling prefabricated elements, respectively a base slab (1), side elements (2) arranged on either side of the base slab and vault elements (4). The structure according to the invention is comprised of at least two adjacent passage sections (S, S') having parallel axis (O, O'), each limited downwardly by a base slab element (1, 1') and upwardly by a vault element (4, 4') and, on the sides, externally by a side element (2, 2') and internally by at least an intermediate pillar (6) bearing on the ground via a sole piece (7) arranged between the longitudinal adjacent sides (11, 11') of the two base slab elements (1, 1') surrounding them . The pillar (6) is provided at its top with a girder (5) having two side walls (52) which form a V so as to provide on either side of a medial plane (P1), two bearing surfaces (53) configured like concave grooves in which are bearing the longitudinal adjacent sides (41) of the two vault elements (4, 4') framing the intermediate pillar (6).</p> |
