The finger expansion joints with teeth consist of two steel panels opposite to each other and in which the comb processing allows a perfect coupling. Each toothed plate is fixed to its relative head; thanks to the perfect fit of the teeth, the continuity of the road is guaranteed and the alternation of expansion and contraction of the roadway is supported.
The finger expansion joint of the 'Finger-C' series is suitable for absorbing movements starting from 50 mm (± 25 mm) and is composed of CORTEN S355J2 WP steel panels shaped like a comb and anchors made with galvanized anchor bolts, nuts and washers concealed in the built-in areas on the upper face.
The finger expansion joint of the 'F Cover' series is suitable for absorbing movements starting from 50 mm (± 25 mm) and is composed of CORTEN S355J2 WP steel panels shaped like a comb and anchors made with galvanized anchor bolts, nuts and washers. disappeared in the recessed areas on the upper face. The substantial difference with the expansion joint of the ‘Finger-C series is that this type has the advantage of covering the structural opening from materials and dirt coming from the road platform.
The Research Agency of the Transport Authority, belonging to the National Academy of Sciences (United States of America) has opted for the use of the "finger" type steel joints on the spans with large movements, compared to the so-called modular joints rail.
The finger expansion joints of the ‘Finger-T’ series are comb expansion joints for 50 mm excursions to be installed at the level of the slab; they consist of a deformable element in EPDM rubber contained within metal profiles shaped like teeth. Steel clamps are welded to the joint to allow it to be anchored to the slab. A drainage EPDM flashing is supplied to cope with the percolation of the water and to guarantee the waterproofing of the structural gap.
