16 Abstract. A pressure relief panel (10) comprises a panel plate (11) which is fastened to a framework (12). The panel plate (11) is adapted to withstand external pressures, such as wind pressure, and is adapted to be released from the framework (12) with the exceeding of an established, internal pressure, for example the occurrence of a pressure of explosion, in an adjacent closed or partially closed space (19), by breaking certain fastening means. The panel plate (11), which consists of thin plate, preferably aluminium plate, is fixed in the framework (12) with a single curved, concavely arcuate contour relative to said space (19) on two respective sides (15c, 15d) of a middle cross-piece (16) in the framework. Said middle cross-piece (16) forms a permanent fastening for the panel plate (11) and forms a resistance to pressure loadings which are exerted against the panel plate (11) from said space (19). End edges (11a, 11b) of the panel plate (11) on their respective sides of the cross-piece are releasably fastened to a respective end piece (15a, 15b) in the framework (12). A wall section includes the pressure relief panel. The panel (10) is provided at its upper and lower ends with a Venetian blind panel (31, 32) with their respective permamently open through-flow passages (33, 34). The Venetian blind panels (31, 32) are arranged vertically flush with the panel (100).
