Steel frame seismic reinforcement method "Smart Fit Method"

Senkushia Co., Ltd. (Headquarters: Minato-ku, Tokyo, Representative Executive Officer: Nobuyasu Kasahara), which manufactures and sells construction materials and related works, has refined the "Smart Fit Method" for reinforcing the base of steel columns. In seismic reinforcement work for steel structures, it is common to attach reinforcement members to the building using welding. However, welding methods require considerable time and effort for work and fire protection, and they also carry the risk of fire during construction. Therefore, there is a demand for safe, reliable, and simple joining methods that do not use fire. In the previous Smart Fit Method, welding was necessary when installing reinforcement columns, but with this refinement, it has become possible to perform work without welding when the existing column is an H-beam. Additionally, the improvement of the toughness index (F value) of the column base has been achieved.

Senkushia Co., Ltd. (Headquarters: Minato-ku, Tokyo, Representative Executive Officer: Nobutaka Kasahara), which manufactures and sells building materials and related construction, has begun selling the "Smart Chronos Method," a brace joint method that replaces traditional welded seismic reinforcement with a no-welding, short-construction-time approach. In seismic reinforcement work for steel-framed buildings, it is common to use welding methods when attaching reinforcement materials to the structure. However, welding methods require significant time and effort for work and fire prevention measures, and they pose a fire risk during construction. Therefore, there is a demand for safe, reliable, and simple joining methods that do not use fire. In response to these challenges, our company has developed the "Smart Attach Method" (brace reinforcement) with the concepts of "no welding" and "improved construction efficiency," which has been well received in seismic reinforcement for factories and warehouses. We have now applied this technology to develop the "Smart Chronos Method," which allows for the installation of brace materials using dedicated SC hardware and bolts.
