EXPANSION JOINTSSM MEG PT RAILWAJ STS TYPES

Expansion joints are designed to ensure continuity between two structural elements and to follow the movements of the structure itself, generally due to:

• Hygrometric shrinkage of concrete; • Thermal degradation of the deck; • Braking actions;• Anti-seismic actions The expansion joints of SOMMA have a range of movement FROM 20 TO 1200 MM, their perfor-mance is guaranteed even in case of high traffic density and in case of constant exposure to external agents.All expansion joints are fitted with a system of drainage and are designed to minimize traffic noise andprovide maximum comfort for passengers in transit.

The expansion joints of SOMMA are designed and manufactured according to ETAG32.

They consist of a central plate covering the gap between the structural elements, vulcanised inside a rubber element. Sliding is ensured by the presence of deformable rubber modules, vulcanised with steel plates and containing stainless steel anti-lifting bars.The sliding capacity of the joint depends on the number of rubber modules of which it is composed. The system is designed so that, when the joint is cut vertically, at least one reinforcement element is always encountered.

The xpansion joints are designed and manufactured according to ETAG32.

The joint panel is 1.5 m in length and is supplied with rubber flashing for water collection and with the fixing system, consisting of anchor bolts, washers and self-locking nuts. It has a water drainage system thanks to the insertion of an aluminium L-profile.

Railway couplings are designed with special measures to be suitable for use in railway structures and to meet RFI requirements. In particular, dielectric rubber is used and a stainless-steel plate goes on the upper surface of the joint to prevent the ballast from penetrating inside.

It is anchored using threaded rods.

STs modular Joints are designed as multiple or single support bar joints systems depending on the requi-red range of movement and the intended application. They are designed to accommodate structural movements through on arrangement of adjacent connecting seals that have a self regulating gap system designed to ensure that all seals open equally. The joints are made up of an arrangement of edge and center beams that run perpendicular to the bridge’s longitudinal axis and are interspersed with neoprene seals. The center beams in turn slide on support beams that are arranged to move along one or both edges. The support beams are designed to allow rotational and sliding movements.

STs modular joints significantly reduce road surface traffic noise and vibration to a minumum and the design approach also results in a continuous water tight connection at both minimum and maximum ope-ning apertures, very durable fatigue free connections and maintenance free components.

INSTALLATIONThe installation of the joint must take place after a sufficient period of settling of the road paving.The diffe-rential yielding of the asphalt due by traffic doesn’t occur near the joint, because the high strength mortars used prevent every lowering.Therefore It is advisable to install the joints after at least 6 months following the opening to traffic on final pavement.Alternatively we invite you to increase the vibro-rolling near the joint, in order to reduce the the gaps and to limit as much as possible the subsequent settling of the pavement.

PRELIMINARY PHASE

• Cut of asphalt;• Removal of the paving and bush-hammering;• Placing of the drainage system;• Preparation of the site of the joint; • of mortar or shrinkage compensating grout to create the support surface of the joint;• Tracing holes.

POSITIONING OF THE JOINT • Positioning of the panels of the joint (in the case of loads over 30 kg, use a lifting tool);• Drilling and grouting of anchors;• Tightening of the anchor nuts with torque indicated on the project;• Realization of the transition areas;• Sealing of the housing slots for the anchors until complete filling.
