摘要： A fire shutter comprises a plurality of substantially planar fire plate elements each having first and second opposite edges and supported so that they are adjacent to each other and turnable about respective parallel axes from a flow-through open position, in which gas-flow passages are formed between the plate elements, to a closed position, in which the first edge of one plate element of each pair of adjacent plate elements is close to the second edge of the other plate element of the pair and the fire plate elements together form a closed barrier. The first edge of the one plate element is provided with a sealing structure including a plane part, which laps over an area adjacent the second edge of the other plate element to lie substantially parallel to the plane of that area of the other plate element, and a transverse part which is substantially perpendicular to the plane part and confronts the second edge of the other plate element, whereby distortion of the other plate element does not create a significant gap between the one plate element and the other plate element.
