Steel beam penetration hole reinforcement method "PosiRing Method" [Shortens steel fabrication time]

A penetration hole reinforcement method that emphasizes welding volume and workability for small to medium-sized properties with many penetration holes below φ300, aiming for labor-saving efficiency!

The Posiring method is a construction technique that reinforces through-holes provided in steel beams. The "Posiring method" being released this time is a product developed specifically for small to medium-sized projects with many through-holes of φ300 or less, focusing on reducing welding volume and improving workability for labor-saving purposes. 【Features】 ■ No need for marking and flipping the beams. This can shorten the manufacturing time of the steel structure. By inserting the protrusion to align with the lower hole, positioning can be achieved, allowing the marking work to be omitted. Additionally, since flipping the beams is not necessary, the manufacturing time of the steel structure can be reduced. ■ Construction is possible with fillet welding. Welding volume can be reduced. The installation is completed by performing fillet welding around the entire circumference of the Posiring. Therefore, after assembly welding, it can be smoothly installed without the need for flipping the beams. ■ It has obtained evaluation from the Japan Building Center. The structural performance and workability have been evaluated based on full-scale experiments and analyses, receiving certification from the Japan Building Center (a public interest incorporated foundation). *For more details, please request materials or view the PDF data available for download.
