摘要 |
<p>A fire closure element comprises a frame (3) defining a flow-through opening which contains an array of turnable plate elements (1) defining a shutter movable between closed and open (15) positions. To prevent thermal stress causing gaps to appear between adjacent edges of closed plate elements a sealing structure (7) is provided. The structure 7 can be bent from the plate elements (Figure 2) or provided by L-shaped members (Figure 1) fixed to edges of the plate elements. <IMAGE></p> |
