摘要

The door has glass wings made of fire-resistant safety glass, movable on top of each other along a level. The wings have complementary contours interlocked into each other during a thermal loading of the wings in case of fire. The complementary contours have recess (4) in one of the wings and a tie bar (5) in the other wing. The tie bar is embedded in an insert and is movable in the recess during thermal loading of the wings.
