Abstract

L'invention concerne un dispositif de fixation de panneau photovoltaïque solaire qui comprend un rail (2) de guidage et une pluralité de composants (3, 4) de blocage par pression ; le rail de guidage est pourvu d'une rainure (21) de serrage de blocage par pression le long de sa direction longitudinale ; un premier bloc (31, 41) de serrage du composant de blocage par pression est apparié coulissant avec la rainure de serrage de blocage par pression, son bloc de pression étant utilisé pour bien serrer un panneau (1) photovoltaïque solaire ; dans la section transversale du rail de guidage, la rainure de serrage de blocage par pression se présente sous une forme semi-enveloppante qui est grande à l'extérieur et petite à l'intérieur et constitue une encoche (212) qui a une forme semi-enveloppante homologue ; en outre, la rainure de serrage de blocage par pression et le premier bloc de serrage qui sont adaptés satisfont à la condition que la largeur de l'encoche de la rainure de serrage de blocage par pression est supérieure à la dimension minimale du premier bloc de serrage homologue et inférieure à la dimension maximale du premier bloc de serrage. De préférence, la manière dont interagissent un composant (5) de patte de support du dispositif de fixation et le rail de guidage est la même que celle entre le composant de blocage par pression et le rail de guidage. En appliquant ce dispositif de fixation, on peut effectuer commodément le démontage et le montage des blocs de serrage du composant de blocage par pression ou le composant de patte de support du rail de guidage et, de ce fait, contrôler efficacement le coût de l'installation pour fixer le panneau photovoltaïque solaire. L'invention concerne aussi un bloc de serrage.
