ANTI-COLLAPSE SYSTEMS FOR FLOORS

The safety of buildings of public and private interest is an extremely current topic. This also applies to critical issues not directly related to load-bearing structures, which can nevertheless pose a risk to human safety. The recent seismic events have caused extensive damage, with significant socioeconomic repercussions. Not only have human lives been put at risk, but the country's economy and its historical and architectural heritage have also been damaged, despite the significant financial resources required to restore entire areas affected by these catastrophic events. OLYMPUS SAFE It allows for immediate solutions to prevent potential damage. Attention has always been paid to increasing the resistance of structures by intervening on those parts of the building that contribute to their load-bearing capacity. However, especially in recent years, following numerous news stories, the importance of elements that in the calculation model do not contribute to the load-bearing capacity of the structure and are therefore considered non-structural has become evident. These are: pots, pans and secondary elements which, although not directly linked to the carrying capacity, can cause economic losses and human lives.

Anti-collapse systems certified at the Istituto Giordano SpA testing laboratories

The OLYMPUS SAFE system includes anti-collapse techniques, i.e. procedures to be implemented in order to combat phenomena of detachment of elements at the intrados of the floors such as hollow cores - elements for lightening the brick-cement floor slab, plaster, etc.; systems that prevent out-of-plane kinematics of the walls, such as the overturning of more or less extensive portions of infill panels, ensuring an effective connection between the structural parts constituting the frame and the partition wall constituting the non-structural element.. The proposed systems consist of the use of bidirectional fiberglass networks with high mechanical resistance and diversified weights, anchored to the structural elements (joists/beams and pillars) using special connection systems. The phenomenon of collapse affects a large portion of the Italian construction industry, especially public buildings (e.g., schools or offices), built primarily between the 1940s and 1970s. Only 50 years later, however, has this issue emerged in force, related to non-structural elements, often overlooked, such as the bricks (so-called lightweight hollow bricks) in the floors. However, while this isn't a purely structural problem (in fact, it is partially so), if they collapse, up to 100 kg of material (plaster and bricks) per square meter of floor can detach and fall. The problem is therefore very serious, especially if we consider a classroom, for example. Olympus SAFE anti-collapse systems can address and prevent this phenomenon, making the environment safe.

The Olympus SAFE anti-collapse systems come in two different configurations:

1

Olympus SAFE dry anti-collapse system
2

Olympus SAFE mortar anti-collapse system

The two methods differ from each other in the use of a structural mortar in which the system is embedded and which provides a greater homogeneity of mechanical response.

Anti-collapsing system for securing brick and cement floors

Installation of the OLY MESH network following the rules indicated above and the assembly diagram Application of connector kits, choosing, based on the structural element to be protected, between: - OLY CONNECT SAFE CE marked for brick and cement floors in correspondence with the beams - OLY CONNECT SQ for wall perimeter contact Cover the system with OLY WALL STRUKTURA F15 structural mortar to a thickness of approximately 1.5 cm. In the case of dry systems, cover with plaster of your choice or with a false ceiling. The system can, however, be left exposed.
