Abstract

L'invention concerne une couverture pour édifices permettant de capter l'énergie solaire comprenant un élément absorbant les rayons solaires en remplacement du toit, incorporant des canaux à travers lesquels circule un fluide caloporteur et dont la partie inférieure est enduite d'une couche de matériau isolant thermique. La couverture est constituée d'une pluralité de panneaux (1) imperméables assemblés au moins par leurs côtés définissant des jointures imperméables. Ces panneaux (1) comportent sur leur face extérieure une planche (2) en matériau thermoconducteur et sur leur face inférieure une pluralité de profilés tubulaires (4) adossés formant les canaux. La planche (2) et les profilés (4) sont en contact avec la couche isolante (5). Les panneaux (1) s'étendent entre un conduit de distribution (6) et un conduit de collecte (7) transversaux par rapport aux profilés tubulaires (4) et disposés de manière adjacente aux conduits tubulaires (4). Ces profilés tubulaires (4) et ces conduits (6, 7) présentent une section transversale et une configuration assurant une résistance prévue pour supporter totalement ou partiellement la charge estimée de la couverture et servent d'éléments de rigidification et de support de la couverture.
