トキワシステム

It absorbs the repeated shaking of earthquakes and enhances the safety of your home.

In the residential construction industry, earthquake measures have become an important issue to ensure the long-term safety of buildings and the peace of mind of homeowners. Particularly, with the recent increase in the frequency of earthquakes, there are concerns about the accumulation of damage to buildings not only from a single major earthquake but also from repeated aftershocks. This leads to increased stress on structural components, which could result in a higher risk of collapse and a decline in the quality of the building. Our seismic dampers for wooden houses protect homes from these repeated seismic movements, enhance structural safety, and provide a safe living environment for homeowners, contributing to the maintenance of the asset value of the house. 【Usage Scenarios】 - New construction and renovation of wooden houses - Contractors and builders - Providing peace of mind to homeowners 【Benefits of Implementation】 - Efficient absorption of earthquake energy - Suppression of building deformation - Maintenance of long-term damping performance - Reduction of maintenance burden
