The "αDamperExII" is a small oil damper that enhances the building's resilience (damping force) by distributing it throughout, thereby suppressing the reduction of strength due to repeated earthquakes. It is easy to install by simply securing it to columns and beams with the included special screws, making the installation cost reasonable. It is compatible with all types of wooden houses and, due to its compact size and lack of need for extensive construction, can also be installed during renovations of existing buildings. Additionally, there is no need for special considerations in design or applications, and it does not impose significant constraints when making future changes to the layout or renovations. 【Features】 ■ Can be installed in all types of wood construction ■ Can be finely distributed in the most swaying outer areas ■ Effective for renovation work ■ Low installation cost ■ No constraints on design or layout *For more details, please refer to the PDF materials or feel free to contact us.

Are earthquake measures and seismic measures sufficient? The current seismic standards in the building code are designed to withstand seismic intensity of 6 strong or higher, but it is also necessary to consider damage from aftershocks, as seen in the Kumamoto earthquake, where significant damage occurred. In this context, an important option is the addition of "vibration control" alongside seismic measures. The Tokiwa System's α Damper ExII reduces earthquake damage to buildings by about half, effectively mitigating the impact of repeated aftershocks. Additionally, it can be implemented without changes to the design, contributing to cost reduction for seismic measures. **Features** - Can be implemented without changes to the design - Suitable as an alternative to seismic and vibration control devices - Contributes to cost reduction - Improves construction efficiency *For more details, please download the catalog or feel free to contact us.*

The α Damper ExII is a hydraulic damping damper that utilizes principles similar to those of a car's shock absorber. By adopting it in addition to seismic construction methods, it reduces deformation caused by earthquake shaking by approximately half, preventing damage to the structural joints and non-structural components of the house. Unlike brace-type damping devices, it is compact and can be distributed around the perimeter, providing stable damping effects. It reduces building damage from earthquakes by about half and is effective against repeated aftershocks. Our reliable and proven damping technology protects you and your loved ones from earthquakes. = Seven Reasons to Choose 'α Damper ExII' = 1. Can be installed in all types of wooden houses (new, existing, traditional frame, 2x4). 2. Highly durable and maintenance-free, with a reassuring 20-year warranty. 3. Easy installation by one person in about half a day. 4. Effectively absorbs the shaking from repeated earthquakes. 5. Low price that allows for standard adoption by housing brands. 6. Layout planning for the α Damper ExII is provided free of charge by the manufacturer. 7.

This document includes numerous photographs of the installation examples of the hydraulic damping device 'α Damper ExII' during renovation work. After the Great East Japan Earthquake, there were approximately 240 aftershocks of magnitude 4 or higher within one year. It has been pointed out that there is a possibility of an early occurrence of the Nankai Trough Earthquake due to the effects of the Great East Japan Earthquake. At Tokiwa System, we propose building homes that can withstand earthquakes with the hydraulic damping device 'α Damper ExII'. *For more details, please refer to the PDF document or feel free to contact us.
