三誠AIR断震システム List of Products and Services

We would like to introduce the "Air Isolation Device," an air-floating seismic isolation device handled by Sansei Co., Ltd. A common drawback of conventional seismic isolation devices is their height, which can affect the equipment mounted on them. However, our product achieves a low-profile design. In vibration tests, we have achieved results where the response acceleration is suppressed to between 20 gal and 30 gal in all cases. 【Features】 ■ Achieves a low-profile design ■ Response acceleration suppressed to between 20 gal and 30 gal in all cases of vibration tests ■ Demonstrates seismic isolation effects from seismic intensity 2 ■ Non-operational state: The device does not shift with small forces due to its seated position ■ Effective in reducing production defects caused by small earthquakes *For more details, please refer to the PDF document or feel free to contact us.

The "ECS-TP method" is a steel pipe pile top plate joint construction method that is simple and very easy to implement, making it suitable for challenging sites. By re-evaluating the conventional foundation construction process itself, we have successfully shortened the construction period significantly while satisfying the structural criteria considered in the design standards, achieving both cost reduction and performance maintenance simultaneously. It has been adopted in pioneering projects that are typically considered difficult, such as "building a compost shed on a slope" and "adding a new roof from the outside of a station building." 【Features】 ■ Zero leftover soil and industrial waste ■ Fewer construction days ■ Usable in narrow spaces ■ Low vibration and low noise, minimizing environmental impact ■ Fewer vehicles required due to less material to be transported *For more details, please refer to the PDF document or feel free to contact us.

"VIBRO" is our new solution proposal to support our customers in solving vibration issues related to structural design that ensures safety, security, and stability. We propose measures to anticipate and avoid potential vibration complaints based on your design themes, and after measuring and analyzing vibration characteristics, we manufacture and install the devices and systems. This can be applied to address fitness vibration complaints in tenant and commercial buildings, as well as to maintain comfortable living conditions and for seismic retrofitting of buildings. [Application Examples] ■ Measures to prevent constant vibration of equipment and to protect equipment functionality during earthquakes ■ Addressing fitness vibration complaints in tenant and commercial buildings ■ Maintaining comfortable living conditions and seismic retrofitting of buildings *For more details, please refer to the PDF materials or feel free to contact us.

The "Air Vibration Isolation Floor" creates an airtight space between the concrete slabs that separate the building's floors and the floor itself, generating an air cushion. By controlling the air pressure according to the intensity of the vibrations, the entire floor is constantly lifted by air, which means that sounds and impacts generated by vibrations are absorbed by the air and cushioning materials, preventing them from being transmitted to the structural framework. As a result, compared to traditional methods that reduce vibrations by installing rubber or springs under the floor, a cost-effective and high-performance vibration isolation solution can be achieved. 【Features】 ■ Cuts vibrations using the power of air ■ Vibrations do not transmit to the building's structural framework ■ Can be installed even on the top floor ■ Easy maintenance with computer control ■ Suitable for live houses and event halls *For more details, please refer to the PDF materials or feel free to contact us.

The "Air Vibration Control System" is an air-floating TMD (Tuned Mass Damper) that combines air and LM (Linear Motion) guides. Under normal conditions, it is seated (stable), but a special air seal is provided between the vibration mass and the base, creating an air vibration control layer. When vibrations are detected by sensors, compressed air is blown between the air vibration control layer and the base, causing it to float instantly (within 0.2 seconds) and begin vibration control. By utilizing the power of air to lift a large mass, it becomes possible to significantly reduce the friction coefficient between the mass and the base. [Mechanism] ■ Normal condition: The base and vibration mass/air seal are seated. ■ During vibration: Compressed air is blown between the base and the air seal. *For more details, please refer to the PDF document or feel free to contact us.

The "Air Seismic Isolation House" is a new system that utilizes the power of air to protect homes, furniture, and most importantly, the safety of families from the shaking caused by earthquakes. When an earthquake occurs, air stored in a tank is instantly sent between the artificial ground and the foundation, lifting the entire building. Since the building is separated from the surface that is actually shaking, the shaking is minimized, preventing not only the collapse of the house but also damage from falling furniture, thus protecting the family. 【Features】 ■ Reduces shaking of seismic intensity 7 to 1/30 ■ Significantly reduces construction costs ■ Annual safety inspections *For more details, please refer to the PDF document or feel free to contact us.
