AbstractA small Greek company has developed an advanced protection system with anti-seismic insulation, maybe extremely efficient, intended to protect buildings and inhabitants in case of earthquakes. The innovator is searching for a research institute for technical cooperation or a construction company to implement and promote the product under license agreement; joint venture agreement is also possible.
1.Following the excavation and application of footing mix, the anti-seismic mechanism bearing surface is constructed by reinforced concrete, in several modes: "rantie" (invert floor) or inverted beam type slab, or (slab made of cubes and connecting beams), depending on the form and the dimensions of the construction required.
2.During reinforcement composition and depending on the project needs, connecting mechanisms shall be positioned, drawing (S1), on the bearing surface of the structure to be made consisting of bundled wire-rope, technically treated as indicated in the instructions of the static design. Drawing No(1).
3.Following the formation of the bearing surface and the ring or cube form rubber insulators shall be positioned in the place of bundle wire-ropes, drawing (E1), the dimensions and hardness of which shall vary according to the project. Drawing No(2).
4. The remainder of the project surface must be filled by its half or up to the entire ring or cube height with cellular cushions made of recycled, technically treated old tires, drawing (E2) & drawing (E3), drawing No(3).
5. Following cushion application, the remaining half space up to the final ring or cube height shall be filled with sand so as to create a working surface for the construction of the building, where conventional structural methods may be applied. Drawing No(4).
The strong swaying that the structure is sustaining during an earthquake is converted to vibration.The cracks or even rupture of joints, which are mainly due to the stiffness of concrete, shall be reduced to a minimum.The squeaking & deafening noise created mainly by the shock shall be attenuated significantly.The use of old vehicle tires shall benefit the structure without inducing contamination to the ecosystem.
The construction frame thickness shall be reduced as the height increases and shall therefore become lighter.The artificial soil shall be definitely better than the existing soil.The elastic foundation method shall benefit a large number of building structures (independent houses, 2-floors and three-floors buildings). Even higher buildings may benefit from it, but it will certainly benefit schools and school complexes as well as small hotel units.Finally, the application range depends clearly on the adoption of the method, along with the benefits arising there from, which shall compensate any financial burden that may occur, depending on the project.
