Abstract

Un panneau de sûreté (10) comprend un panneau (11) qui est fixé à une charpente (12). Le panneau (11) est adapté pour résister à des pressions externes, telles que la pression du vent, et pour se détacher de la charpente (12) lors du dépassement d'une pression interne établie, par exemple la survenance d'une pression d'explosion, dans un espace adjacent clos ou partiellement clos (19), par rupture de certains moyens de fixation. Le panneau (11), lequel consiste en une plaque mince, de préférence une plaque d'aluminium, est fixé à la charpente (12), par un seul contour à courbure concave par rapport audit espace (19), sur les deux faces respectives (15c, 15d) d'une traverse centrale (16) dans la charpente. Ladite traverse centrale (16) forme une fixation permanente pour le panneau (11) et constitue une résistance aux contraintes de pression qui s'exercent contre ledit panneau (11) depuis ledit espace (19). Des bords terminaux (11a, 11b) du panneau (11) sur leurs côtés respectifs de la traverse sont fixés de manière amovible à une pièce terminale respective (15a, 15b) dans la charpente (12). Une section paroi comporte le panneau de sûreté. Le panneau (10) est pourvu, à ses extrémités supérieure et inférieure, d'un store vénitien (31, 32), leurs passages respectifs d'écoulement continu (33, 34) étant ouverts en permanence. Les stores vénitiens (31, 32) sont disposés verticalement de niveau avec le panneau (100).
