The "lens-type seismic damper" is a simple structural seismic system that efficiently absorbs earthquake energy. The key lens-shaped panel uses low-yield-point steel (LY material), which has significantly greater elongation performance compared to conventional steel materials. This high elongation performance accurately responds to the intense shaking caused by earthquakes, efficiently absorbs earthquake energy, and minimizes damage to buildings. 【Features】 ○ A higher-grade seismic damper is used in the earthquake energy absorption section → Utilizes low-yield-point steel with significant elongation characteristics → Lens shape provides safety even in major earthquakes ○ Maintenance after a major earthquake is easy and low-cost → Damper replacement is simple ○ Obtained general evaluation from the Japan Building Center (acquired on June 15, 2012) For more details, please contact us or download the catalog.

The "Disk Shia Key" is a revolutionary joint component that can be applied to "SRC structures" and "buildings with low concrete strength," which have been considered difficult for joint connections of reinforcement materials. It consists of an embedded disk and anchor bolts with extended functions. This technology is user-friendly and can be applied to various reinforcement methods such as seismic braces and strength-type steel braces, achieving seismic reinforcement work with low cost, short construction periods, and low noise. It has obtained a technical performance evaluation from the Architectural Research Promotion Association. 【Features】 ○ For seismic reinforcement of SRC structures ○ Capable of accommodating low concrete strength ○ High joint performance and strong cost competitiveness ○ No need for roughening, reduced construction noise and dust ○ Adaptable to various reinforcement materials For more details, please contact us or download the catalog.

The "Toggle Seismic Control Method" is a technology that controls the seismic energy transmitted to buildings. The characteristic of this method is that it efficiently absorbs seismic energy through a mechanism that applies the principle of leverage. Additionally, this mechanism allows for the use of dampers that are more compact than traditional ones. 【Features】 ■ It is possible to achieve seismic resistance at a low cost with fewer installation points. ■ On-site construction can be completed in a short period. ■ Installation points can be determined according to the building's specifications. ■ Construction can be carried out while the building is "in use." ■ It can also respond to repeated aftershocks. ■ The device is essentially maintenance-free. *For more details, please request materials or view the PDF data from the download section.
