FIP ARTICOLI TECNICI S.R.L.

The structural bearings are restraining devices used in structures, bridges and buildings, in order to precisely convey loads and restrain set degrees of freedom of movement. The range of FIP INDUSTRIALE structural bearings includes: all the types made of steel all the types made of rubber In addition to traditional types, FIP INDUSTRIALE also makes special devices such as anti-lifting, load measuring bearings, bearings for incrementally launched bridges etc. TYPES: Pot bearings Reinforced elastomeric bearings Sferopol bearings Cylindrical hinge bearings Special bearings

They protect buildings, bridges, flyovers, or any other facility, changing their reaction to the seismic action or other dynamic actions (for example wind). Most seismic devices are used within the innovative approach to seismic engineering, to change the seismic reaction of a structure by seismic isolation and/or energy dissipation. Namely: • ISOLATORS: they limit the acceleration transferred to the structure and reduce inertial stress by increasing the oscillation period. • DAMPERS: they dissipate part of the energy transferred to the structure according to their constitution, based on which they are divided into two large families, speed-dependent devices and displacement-dependent devices. On the other hand, FIXED RESTRAINT DEVICES are traditionally used in the traditional approach to seismic engineering, to transfer horizontal stress. TYPES: Seismic isolators Speed-dependent devices Displacement-dependent devices Fixed restraint devices

They permit displacements and rotations between abutted structural parts, ensuring continuity of the carriageway and watertightness. They come in a wide range of formats, each format having a certain movement range to accommodate, with only the types of materials used remaining constant. Based on a design of reinforced rubber modular elements, FIP INDUSTRIALE expansion joints offer the following advantages: simple installation simple and cost-effective inspections and maintenance minimal noise and vibration ultimate comfort for passengers in transit smooth running surface optimum functioning and durability of all components minimal interference with the structure format easily adjusted to many shapes to accommodate layout of structure and design engineers' preference several different types of anchorage to suit customer requirement. The series of expansion joints available are labelled as follows: Reinforced rubber road joints Finger road joints Under pavement road joints Re

They include a broad range of connection systems for bridge segments, gaskets, guidance rods, adhesives, packers, lifting-injection and grounding systems. FIP INDUSTRIALE can design, develop, test and supply any accessory for bridge segments, in every case in which tunnels are mechanically excavated by means of TBM mills which results in the use of prefabricated bridge segments. It can also supply flat jacks, bentonite or vulcanized rubber hydroexpansive gaskets for any type of tunnels and other structures which do not imply TBM mills TYPES: Watertight gaskets Adhesives Load spreading pads Inserts Biblock systems and bolts Guidance rods Flat jacks Hydroexpansive gaskets

They mitigate the sound effects of road, highway and railway traffic, with low-environmental-impact integrated solutions. In order to reach the best noise abatement results and environmental and landscape integration, FIP INDUSTRIALE is able to perform: local sound monitoring activities; assessment of the visual environmental impact; design and building of noise barriers; sound testing of built structures. TYPES: Tecnowall metal panels Tecnowall wooden panels Tecnowall clear panels Tecnowall concrete panels Tecnowall recycled plastic panels Tecnowall mixed panels Elliptical reducer Industrial noise barriers

Vasoflon® are confined elastomeric disc structural bearings. Rotations around any horizontal axis are ensured by the deformability of a non-reinforced rubber disc, or bearing, confined within a steel monolithic base (pot). The elastomer acts as a fluid which, subject to a triaxial pressure, opposes weak resistance to deformations and simultaneous strong vertical stiffness. In addition to vertical compressive loads, Vasoflon® bearings are capable of transferring forces and/or permit sliding in one or more directions of the horizontal plane depending on the different bearing types. In movable bearing types, the mutual sliding of two plane surfaces, one of stainless steel and the other of PTFE, ensures the bearing's translation. TYPES: Vasoflon ® bearings, fixed type Vasoflon ® bearings, undirectional type Vasoflon ® bearings, free sliding type

These are structural bearings consisting of an elastomeric core in which one or more steel laminates are inserted, hot vulcanized to the rubber. The presence of the laminates determines a vertical (axial) stiffening effect and the simultaneous reduction in the rubber swelling. Curing has two purposes: one is to convey the rubber tangential actions to the laminate and the other is to ensure the protection of steel against corrosion. Reinforced elastomeric bearings Fixed Elastofip (EF) bearings are a cross between the fixed and free sliding type of bearings, as they permit deformations in all planar directions, but at the same time produce elastic reactions proportional to the deformations. Rotations around any one axis are permitted by the rubber deformability. These bearings are divided into two types: WITHOUT MECHANICAL ANCHORS Neoarm bearings

Sferopol ® structural bearings are spherical hinges in which the rotations about any horizontal axis are ensured by the sliding of a convex steel element in a monolithic concave element coated in SMF special sliding material, consisting of UHMWPE (Ultra High Molecular Weight Polyethylene), which is resistant to wear and tear and significantly extends the life of the bearings and the structure. In addition to compressive loads, Sferopol® bearings are capable of transferring forces and/or permit sliding in one or more directions of the horizontal plane depending on the different bearing types. In movable bearing types, the mutual sliding of two plane surfaces, one of stainless steel and the other of SMF, ensures the bearing's translation movements. TYPES: SF Sferopol ® bearings, Fixed type SU Sferopol ® bearings, guided type, longitudinally sliding SU Sferopol ® bearings, guided type, transversally sliding SM Sferopol ® bearings, free sliding type

In this class of structural bearings rotation is permitted around just one horizontal axis. Its use is recommended whenever a high degree of stiffness against transverse rotations is considered necessary. Their elongated rectangular shape along the rotation axis is especially suitable if there is limited space available in the perpendicular direction to the rotation axis. TYPES: Cernoflon Rockflon

Adding some supplementary features to the basic bearing types, FIP INDUSTRIALE can also produce special bearings, suitable for targeted purposes. These are the main types: Negative load bearings Also known as "anti-lifting" or "double-acting" bearings. These devices are also capable of resisting vertical tension loads, commonly denominated "negative". Load measuring bearings They permit in-situ measuring of vertical loads acting on the bearings. Depending on the technology used, measurements can be made next to the bearing or remotely, at any time of the bearing life span. Bearings with dampers These are a combination of one multidirectional or unidirectional bearing with hysteretic and/or viscous dampers. They are also called "flat sliding isolators with dampers". Bearings with shock transmitters Sliding bearings coupled with shock transmitters. In case of sudden movements, for example seismic movements, the shock transmitters prevent the relative movements of the structural eleme
