ABSTRACT:
An elevator shaft closure and a method of fulfilling fire protection requirements for the same include a shaft door frame having in the region of the closing edge of the frame with a door leaf of at least two door frame parts attached to a building and connected together with a thermally separable material. Under a predetermined stress, the connection between the door frame parts is released and one of the door frame parts displaces in front of the door leaf while the other door frame part substantially retains its original shape.
