[Construction Example] α Damper EXII Renovation Work

[Construction Example] α Damper EXII Renovation Work

Ideal for building homes that withstand earthquakes! Case study of renovation work using "α Damper Ex II".

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.

Download materials explaining the booklet "What are Seismic Resistance, Vibration Control, and Isolation?"

Seismic resistance grade maintained by seismic dampers - Building homes that can be lived in after a major earthquake - "What is necessary for earthquake-resistant housing?"

This document explains three earthquake countermeasures to protect homes from major earthquakes: "Seismic Resistance, Seismic Control, and Base Isolation." It includes the characteristics and overviews of each method, as well as experiential information. We also introduce cost-effective seismic measures, such as "Seismic Control Devices," to prepare for unexpected earthquakes and unforeseen expenses. [Contents] ■ Japan is a country prone to earthquakes ■ Seismic Resistance, Seismic Control, Base Isolation ■ In the event of a major earthquake, if asked, "Will Japanese houses collapse?" the likely answer is "They will not collapse." *For more details, please refer to the PDF document or feel free to contact us.

Seismic control device for wooden houses αDamperExII (α Damper ExII)

Seismic control device for wooden houses αDamperExII (α Damper ExII)

It absorbs the shaking of earthquakes and reduces building deformation by about half. Over 10,000 buildings in total!

The Kumamoto earthquake that occurred on April 14, 2016, made us re-recognize the dangers of direct earthquakes. The current seismic standards of the building code are set to withstand seismic intensity of 6 strong or higher, but it is also necessary to consider the damage from repeated aftershocks, as seen in the Kumamoto earthquake, which caused significant damage to buildings. This is where the option of "damping" in addition to seismic resistance becomes important. The Tokiwa System's α Damper ExII reduces earthquake damage to buildings by about half and is effective against repeated aftershocks. Our reliable and proven damping technology will protect you and your loved ones from earthquakes. Seven reasons to choose the 'α Damper ExII': 1. Can be installed on all types of wooden houses (new, existing, traditional frame, 2x4). 2. Highly durable and maintenance-free. Comes with a reassuring 20-year warranty. 3. Simple installation that can be done 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. Over 10,000 units installed, trusted by major builders.

Wooden house seismic control device 'αDamperExII'

Wooden house seismic control device 'αDamperExII'

Efficiently absorbs earthquake vibrations! A compact oil damper that can be installed in both new and existing buildings.

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.
