It is a seismic resistance construction method that joins seismic braces using epoxy resin and anchors in two different ways.
Compared to conventional methods, the number of post-installed anchors can be reduced, and since roughening of the existing structure is unnecessary, noise, vibration, and dust can be minimized, allowing for construction while remaining in the building. By adjusting the number of post-installed anchors on the existing framework, reinforcement effects can be secured as needed. Due to the indirect connection with head-mounted studs, the lap length can be reliably secured, ensuring high quality. This method can also be used as a steel brace with openings.
