Post-installed anchor bolts that allow for extraction after use!
The "R Anchor" is an anchor bolt used for the installation of temporary components, which can be completely removed after use by extracting all parts. It is a post-installed anchor bolt that allows for complete removal. The anchoring part is coated with a special coating, enabling it to be extracted simply by turning it counterclockwise with a wrench after use. After extraction, non-shrink mortar or similar materials can be filled in, significantly reducing concerns about structural deterioration compared to traditional methods of cutting and leaving anchor bolts in place. Additionally, it can accommodate future construction that requires drilling in the same location. **Features** - Compatible with large diameter bolts (up to M39) - Can be installed at low temperatures (minimum usable temperature -10°C) - No need for concrete chipping or cutting of anchor bolts during removal - Reduces construction time and noise

Company information
Sun Road is the Path to the Sun A road that shines brightly and warmly, always the most positive and cheerful path, started in 1978 with such a wish. From traffic safety facilities to slope protection work and building civil structure repair and reinforcement, people around the world are realizing the neglect of material civilization and are trying to return to spiritual civilization. In such times, we aspire to preserve our valuable construction structures without destruction, using environmentally friendly methods for repair and reinforcement, and we are continuously honing our skills and conducting research and development. Focusing on the Hozen method (bridge reinforcement method), we established the Japan Construction Preservation Association in 1999 and are expanding nationwide. Our management philosophy is to help create a better environment to protect the Earth, and we aim to contribute, even in a small way, to the progress and improvement of humanity by working well, thinking well, and studying well, while fostering people and building a company.
