Abstract

La présente invention concerne un ensemble d'accrochage de panneaux photovoltaïques (60) qui comprend une entretoise de forme cylindrique (70) jointe de façon coopérative à une cheville de forme spéciale (80) au moyen d'une tige entièrement filetée (100). Un boulon (101) est dimensionné et formé pour entrer en contact de façon opérationnelle avec la cheville (80) pour fixer la position relative de celle-ci (80) et du boulon (101). Un joint caoutchouc (110) est utilisé pour favoriser l'étanchéité à l'eau lors de l'installation et pendant l'utilisation de l'ensemble d'accrochage (60). Une plaque en relief (112) peut servir à prévenir les dommages dus à l'installation sur des matériaux de couverture généralement plus fragiles tels que des bardeaux bitumés ou un revêtement de toit composite analogue (128). Un manchon en caoutchouc (120) est utilisé pour faciliter le positionnement de la cheville (80) pendant l'installation de l'ensemble d'accrochage (60). Des crochets (180, 200) servent à fixer un ou plusieurs panneaux photovoltaïques (170) à l'ensemble d'accrochage (60).
