ABSTRACT:
A closure (10) for a building which is inhibitive to explosive effects and with which an opening in a building can be closed off comprises a filling (3) as well as frame elements (1, 2) which enclose the same substantially in a circular fashion. Said frame elements (1, 2) are connected in a non-positive way by means of fastening elements with parts (6) of the building which are adjacent to the opening. In order to achieve a secure connection which withstands high loads between the closure (10) and the part (6) of the building made of building materials of low strength, it is proposed rectangular brackets (4) are fastened to the frame elements (1) on at least two opposite sides of the closure (10). At least one tensile leg (7) each of the brackets (4) extends close to the reveal (L) of the opening. At least one supporting leg (8) each of the brackets (4) extends at a distance from the visible side (9) of the part (6) of the building adjacent to the opening.
