摘要
The multi-wing fire protection door (10) has fire protection door wings (14,18) swiveling to vertical axes so that the fire protection wings detect each other in the closed state of the fire protection door. The fire protection door wings are constructed by jacket sheets (26,30) with a filling (34). The jacket sheets are formed such that the sheets get caught each other or behind-seized in the closed state.
