Abstract:
1. An explosion resistant closure arrangement of a building closure in an opening of a wall of a building, comprising: an opening in a wall of a building, wherein said opening is bounded by a boundary surface being a jamb surface or sill surface of said wall spanning between first and second major wall surfaces of said wall; a mounting arrangement that is connected to said wall in a force transmitting manner and that includes first and second countersupport surfaces, wherein said countersupport surfaces are located along said boundary surface within a thickness range of said wail between said first and second major wall surfaces of said wall, wherein said first countersupport surface is arranged closer to said first is major wall surface and faces toward said second major wall surface and said second countersupport surface is arranged closer to said second major wall surface and faces toward said first major wall surface, and wherein a receiving space is formed between said first and second countersupport surfaces; a building closure that is received in said opening, and that comprises a filler panel and a frame arrangement extending along lateral edges of and carrying said filler panel, wherein said frame arrangement includes a mounting part that is received in said receiving space between said first and second countersupport surfaces; and a first damping element arranged in said receiving space between said mounting part and said first countersupport surface, wherein said first damping element comprises a plastically deformable metal element and is free to deform in said receiving space so as to damp a first force that may act an said building closure and be transmitted from said frame arrangement through said first damping element to said first countersupport surface and thence to said wall.
