Building closure in explosion-resistant design with retaining device between window frame and casement

摘要

The invention relates to a building closure (1) in an explosion-resistant design, comprising a frame (2), a wing frame (4) rotatably mounted in the frame (2) about at least one axis of rotation (3, 3 ') by means of at least one fitting element (11). , a filling (5) fastened in the sash frame (4), a retaining means (14) coupling the sash frame (4) to the frame (2) or to a fastening element (12) of the frame (2) in the form of a traction means (15) which is connected to both the casement (4) and the frame (2) or the fastening element (12) of the frame (2) in a force-transmitting manner and has a length such that the casement (4) from a closed position (10 ) by turning about the axis of rotation (3, 3 ') in an open state can be converted, wherein in the event of an explosion-related tearing out of the sash (4) from the frame (2) of the sash (4) by means of then a holding force transmitting traction means (15) in a catching position at a defined distance from the frame (2) is durable. In order to develop a building closure of the type described above so that despite the traction means in a simple manner a proper operation of the wing is ensured, it is in the closed position (10) existing offset (V) between a force introduction point (24) of the present invention Traction means (15) on the frame (2) and a force introduction point (24) of the traction means (15) on the wing frame (4), wherein the offset (V) in the longitudinal direction of each one force introduction point (24) having profile piece of the frame ( 2) and the sash (4) in its closed position (10).
