Earthquake strenghtening

A multifaceted company that puts the safety of its employees first.

We have successfully completed earthquake-proofing on over 600 buildings, amounting to approx. 1,300,000 sq metres, designing over 9000 different earthquake strengthening elements capable of bypassing existing systems/services without interfering with company life.
Our aim is to make every concrete building erected prior to 2008 earthquake proof so that businesses and their workers can carry out their activities and duties in a totally safe environment and with the utmost peace of mind.

Our Earthquake strenghtening devices

Enabling companies to reduce seismic risk in their precast concrete buildings with the installation of earthquake strengthening devices designed and commissioned by us.

primary beam connections
connessioni travi primarie per l'adeguamento sismico prefabbricato

Primary connections for fastening between columns and prestressed RC beams of various kinds, such as I-, H-, L- and inverted T- floor or roof beams.

connessioni travi primarie per l'adeguamento sismico prefabbricato
Beam – pillar constraint system by means of a steel strut to bypass the electrical conduit
Inverted T beam constraint system – pillar without drilling the same
Rectangular beam – pillar constraint system by means of a box profile using the free side of the pillar.
Beam – column constraint system using a single composite profile connected to both beams, exploiting the free side of the column.
Rectangular beam – pillar restraint system through L-shaped profile with stiffeners.
I-column beam constraint system – column by means of an angular profile with stiffeners and bars passing through the beam.
roof beam connections
connessioni tegoli in intervento di adeguamento sismico capannone prefabbricato

Connections between elements like beams and secondary elements like double tees, folded plate units and other types of precast prestressed RC roof units.

Constraint system tile – box beam through shaped profile with stiffeners.
Bonding system for double ribbed tile – double slope beam by means of coupled profiles. Connection of the two ribs in order to make them collaborate.
Tile – beam constraint by means of a connecting rod system with L-shaped plate to prevent the loss of the support of the tile.
Second application on the tile – beam constraint by means of a connecting rod system with connection to a beam cast on site.
Constraint system wing tile – double slope beam through shaped profile with stiffeners.
Beam – T-pillar constraint system by means of a double angular profile, aimed at preventing the loss of support of the beam following a seismic event.
secondary element connections

Connections between secondary precast elements such as vibrated rc flat or sawtooth slabs including connections between roof structures.

Prefabricated gable constraint – tile by means of metal connection plates and screw anchors.
Bracing system for fixing the roof tile.
Fixing system of the roofing sheets to the double slope beam by means of shaped metal profiles and screw anchors.
precast panel connections

Connections between main structure and infill panels produced using metal elements or with cables and tensioners

Horizontal panel – pillar constraint by means of an angular profile with horizontal slot to allow it to slide.
Retaining system of the panel by means of metal profiles connected to the roofing tile, aimed at preventing it from overturning out of plane.
Panel retention system by means of a steel tie rod connected to the roofing tile.
connections outside of the building

Connections between the various precast elements made from the outside of the building without interacting with the manufacturing and business processes going on inside

Take a look at the gallery of connections outside of the building
Fixing of the infill panels performed from the outside.
Tile – beam constraint system by means of steel profiles with intervention from the roof.
Fixing the tile – beam through the creation of pillars with intervention from the roof, in order not to produce dust inside the building and to avoid business interruptions.
Panel – pillar constraint system by means of threaded bars installed from the outside. The use of blind nuts allows to reduce the visual impact of the fastening.
upgrade work

seismic improvement work with the goal of improving the building’s overall seismic performance.

Take a look at the gallery of upgrade work
Roof bracing system made with steel beams and steel rope tie rods
K bracing aimed at improving the overall resistance of the building against seismic forces
Intervention through steel jacketing of pillars to increase their resistance to seismic actions
Steel jacketing allows to increase the resistance of the product without significantly increasing its size
Diagonal bracing system made using commercial profiles (UPN) in order to improve the overall seismic behavior of the building
