Description

The invention relates to an element for fixing (3) at least one modular coating blade (1) to a supporting structure (2), said element comprising: a base provided with a plane support face (6) to be fixed onto the supporting structure (2), and a fixing face (7) from which at least one protruding part (8) extends orthogonally, said protruding part to be engaged in a corresponding recess (4) in the blade (1). The projecting part (8) comprises tenons (10) on one free end (8c), said tenons progressively enlarging towards the fixing face (7) and facing an internal edge (19) of the recess (4), preventing the blade (1) from being removed. According to the invention, the protruding part (8) comprises a full tongue (8a) provided with means for rigidifying the same with the fixing face (7), the free end (8c) of said tongue being formed with the front ends of the tenons (10) joining at an acute angle, and the tenons (10) being separated from the full tongue (8a) adjacent to the rear ends thereof opposing those forming the acute angle.

La présente invention concerne un organe de fixation (3) d'au moins une lame (1) modulaire de revêtement sur une structure de support (2), comportant - une base présentant une face d'appui (6) plane destinée à être fixée sur la structure de support (2), - une face de fixation (7) à partir de laquelle s'étend orthogonalement au moins une partie saillante (8) destinée à s'engager dans un évidement (4) correspondant ménagé dans la lame (1), - la partie saillante (8) comportant à une extrémité libre (8c) des tenons (10) s'élargissant progressivement en direction de la face de fixation (7) - les tenons (10) étant destinés à se positionner en regard d'un bord interne (19) de l'évidement (4), empêchant alors tout retrait de la lame (1). Selon l'invention la partie saillante (8) comporte une languette pleine (8a), laquelle est pourvue de moyens de rigidification avec la face de fixation (7), et dont l'extrémité libre (8c) est formée avec les extrémités avant des tenons (10) se rejoignant en angle aigu, les tenons (10) étant séparés de la languette pleine (8a) au voisinage de leurs extrémités arrière opposées à celles formant l'angle aigu.
