Improvement of constructability and cost-effectiveness, shortening of construction period! Seismic joint construction method that meets Level 2 seismic motion.
The "TB (Touch Bond) Method" is a seismic jointing method that achieves resistance to level 2 earthquake motions by connecting with a one-touch joint and bonding with a highly elastic adhesive that excels in elongation capability. Connection is completed simply by pushing the joint bar into the socket, and then injecting the high-elasticity adhesive into the designated space. Compared to conventional methods, this significantly reduces the amount of work required, improving construction efficiency and cost-effectiveness, and shortening the construction period. 【Features】 - Improved construction efficiency and cost-effectiveness, shortened construction period - Clears level 2 earthquake motions - Continuity, water tightness, and seismic resistance on all bonding surfaces - Water tightness equal to or greater than elastic sealing - Accommodates shear displacement *For more details, please refer to the PDF document or feel free to contact us.
