FIELD: construction. ^ SUBSTANCE: door or gate with at least partial peripheral sealing facility, with retention strip made of metal, inside of which seal is arranged. Seal is arranged with the possibility of pneumatic actuation and is arranged in zone of opening for door or gate for air impermeable adjacency to mount frame made of metal, with fastening facilities arranged aside seal for fixation of electroconductive contact elements. Elements for electric contact pass in direction of longitudinal axis of seal, with their end over sealing surface, which is directed towards opening for door or gates so that when door/gate is closed, contact elements are pressed for electric contact with mount frame at the side of building, and sealing surface is at the same time in air permeable contact with mount frame. ^ EFFECT: reliable protection of opening in building against high-frequency electromagnet pulses or against electromagnetic fields. ^ 20 cl, 8 dwg |
