Technical materials featuring construction achievements are being distributed. A reduction of approximately 79% in process time is possible compared to conventional methods!
The "R Anchor" is a post-installed anchor bolt that can be removed after use, such as for temporary materials. It uses acrylic resin instead of conventional epoxy resin as the adhesive for the anchor bolt. Acrylic resin has the following features: - Can be installed at low temperatures down to -10°C - Short curing time (Summer resin: approximately 70 minutes at 25°C, Winter resin: approximately 120 minutes at 5°C) - Can be applied to wet surfaces Additionally, during installation, it eliminates the need for the setup and removal of pipes and sealing materials, as well as resin measurement and mixing tasks, allowing for approximately 79% reduction in process time compared to conventional methods. ★ Technical materials containing construction achievements are available upon request ★ [Contents (excerpt)] - About acrylic resin - Performance verification tests - Construction achievements [Applicable examples] - Temporary equipment during bridge construction (preventing overturning and falling during girder installation, etc.) - Fixing brackets for jack-up during bearing replacement - General civil engineering work, construction work, factory equipment fixation, etc. *For more details, please refer to the catalog or feel free to contact us.
