Aluminium body structural expansion joints with a pivotal movement between the metal flanges and a synthetic rubber insert. Designed to bear structural movements of large sized buildings or compounds of buildings. They are installed over the spaces existing between two semi-detached parts of a building of smaller entity or between different beam bays. They can connect and close these inter-spaces adjusting themselves up-wards, downwards and even transversally, according to the shrinkage-settlement movements of the whole building, either cyclic or permanent. Within the flooring bays frame created with the structural joints, a further surface subdivision with a suitable pattern of movement / expansion joints should be always provided for. See relevant indications on page 263. L 70 Illustrated scale dimension 1:2 (GR 500 AN*) INSTALLATION: • Position the metal insert into the lateral flanges. • Slip the rubber infill into the metal insert before aligning the expansion joint in site. • It is advisable to protect the rubber with some adhesive tape to avoid any cement spot. • Fasten the lateral flanges into the substrate with suitable fixing plugs (7 every linear meter, i.e. one every 30 cm, proceeding parallel on the two sides). • Lay then the screed over the structural joint flanges and tile as normal.
