Abstract

L'invention concerne un élément extérieur (1) de bâtiment pour recevoir un élément solaire (2) pour accumuler et/ou convertir l'énergie solaire, avec au moins un cadre (3) à base de béton. Le cadre (3) est réalisé sous forme de corps moulé (4) auto-portant d'une seule pièce, qui est adapté à la fois dans sa forme extérieure (41) au site d'installation, et dans sa forme intérieure (42) aux composants qu'il doit recevoir et à un recouvrement (5) transparent à la lumière. Le corps moulé (4) présente au moins une première rainure (43) avec un joint d'étanchéité élastique (6), qui forme la garniture d'étanchéité entre le recouvrement (5) transparent à la lumière et le cadre (3). Lors de la fabrication de l'élément extérieur (1) de bâtiment par coulage de béton renforcé par des fibres de verre, plusieurs composants différents peuvent être coulés directement en même temps, en particulier des passages de câbles, des conduites pour fluide caloporteur, des fixations et similaires. L'élément extérieur de bâtiment selon l'invention permet une utilisation en tant qu'élément à l'intérieur du toit, sur le toit, en façade ou posé sur un toit plat, et du fait de ses matériaux, est résistant aux intempéries pendant au moins 50 ans et est de fabrication économique. Grâce à l'utilisation de béton au lieu de plastique ou de métal léger, la charge au feu d'un bâtiment avec un élément extérieur de bâtiment selon l'invention est d'une part réduite. D'autre part, par coulée de câbles avec leur isolation dans le cadre (3) et du fait des connecteurs protégés, l'inflammation de l'isolation et donc aussi la pénétration de l'eau d'extinction sont évitées, de sorte qu'en cas d'incendie, l'émission de gaz toxiques pour la santé est évitée et le risque d'une électrocution lors de l'extinction à l'eau est réduit.
