  • FIG. 5 shows the 3-D view of FIG. 4 provided with side covers 210. This results in a completely enclosed, but downwardly open body, whereby the above-described aerodynamic effects of Ballastreduzitation come into play better.

Abstract

L'invention concerne un système de montage non soutenu modulaire pour le montage de modules plats quelconques (170) sur des toits plats, comportant au moins un élément de base pour le montage d'un module plat individuel (170). L'élément de base comporte les composants suivants: une première et une deuxième jambe de force de module (110) disposées parallèles; un premier et un deuxième support de module avant (120) ayant une première longueur, une première extrémité du premier support de module avant (120) étant fixée à une première zone (111) de la première jambe de force de module (110), et une première extrémité du deuxième support de module avant (120) étant fixée à une première zone (111) de la deuxième jambe de force de module (110); un premier et un deuxième support de module arrière (130) ayant une deuxième longueur, une première extrémité du premier support de module arrière (130) étant fixée à une deuxième zone (112) de la première jambe de force de module (110), et une première extrémité du deuxième support de module arrière (130) étant fixée à une deuxième zone (112) de la deuxième jambe de force de module (110), la première longueur étant supérieure à la deuxième, et les deuxièmes extrémités du premier et du deuxième support de module avant et arrière (120, 130) étant prévues pour la fixation du module plat (170), de telle manière que le module plat (170) adopte un angle par rapport aux jambes de force de module (110), prédéfini par la première et la deuxième longueur et supérieur à 0; un capot frontal (150) recouvrant l'espace entre les deux supports de module avant (120); et un capot arrière (140) recouvrant l'espace entre les deux supports de module arrière (130), l'élément de base comportant également un dispositif de fixation pour le montage d'un autre élément de base ou d'un élément d'extension du système de montage non soutenu modulaire.
