protection of expansion joints with induced movement
“SEISMIC WALL JOINT” for the protection of expansion joints with movement capability up to 100%, with fire resistance EI 120 V-H-M100-F-W0 to 400, consisting of a triple layer of boards th. 12,7 mm each, total thickness 38 mm and width 600 mm so as to have a lateral overlap onto the wall. The boards will be laid with horizontally staggered joints and screwed to the existing wall on one side only, fixed with self-drilling screws, or screws with anchors, size 5x120 mm placed at 300 mm centres. On the free side, the boards are screwed together by means of dedicated steel screws placed at 600 mm centres. At the point of contact between the “SEISMIC WALL JOINT” and the moving part of the wall there is an intumescent gasket, size 30x1,5 mm, called “GB-T”, inserted in a dedicated housing formed by milling. The joint allows an induced movement of 100%.
