By implementing vertical seismic isolation for the entire floor, the vertical acceleration on the floor during an earthquake is reduced.
Our company offers an air pressure-controlled up-and-down seismic isolation floor system. The air springs softly support the floor and reduce the forces of an earthquake. By supplying compressed air generated by a compressor to the air springs through a leveling valve while adjusting the air volume, the height of the seismic isolation floor is kept constant. Please feel free to contact us if you have any inquiries. 【Features】 ■ The natural frequency remains constant even when the load changes, so the seismic isolation effect hardly changes regardless of the size of the load or the position of the equipment on the isolation floor. ■ The use of air pressure-controlled friction dampers ensures a good walking experience. ■ By installing it in a horizontally seismic-isolated building, three-dimensional seismic isolation is made possible. ■ The space between the fixed floor and the seismic isolation floor is sealed with special hardware, preventing the intrusion of objects and dust. *For more details, please download the PDF or feel free to contact us.

Company information
Currently, the Earth is facing various environmental issues, including global warming caused by environmental destruction. We have entered an era where it has become difficult to maintain our living environment without reducing and improving the burden on the global environment. In this context, Yakumo Corporation has consistently aimed for "integration with the environment" for the past 45 years since its founding, developing as a comprehensive engineering company specializing in vibration and sound. To secure a quiet living space in urban areas, we implement measures against vibrations and noise generated from railways, vehicles, construction and civil engineering sites, and factory machinery, contributing to the improvement of living environments. Additionally, we utilize the vibration and sound technologies we have cultivated over the years in acoustic facilities such as halls and studios, as well as in sports floors like gymnasiums and martial arts dojos, enhancing acoustic effects and improving the performance of sports facilities. In recent years, we have advanced the development of technologies for seismic isolation, vibration control, and damping, and by introducing floor isolation and equipment isolation, we now prevent damage from earthquakes to essential systems such as computers and communication devices used by various companies and public organizations, as well as to valuable artworks and cultural properties. Yakumo Corporation will continue to strive towards becoming a "global environmental company" united as a whole to protect the global environment, and we will keep working on research and development.
