<Are you facing any of these issues at your construction site?> ■ I want to completely remove bolts without chipping after use. ■ I do not want to leave cut anchor bolts inside the existing concrete. ■ I do not want to create vibrations or noise. Temporary anchor bolts are often cut and processed after use, but the remaining bolt pieces can rust, causing deterioration of the concrete. Additionally, vibrations from chipping work can damage the concrete, and noise can lead to problems at the construction site. 【Features】 ■ Bolts can be extracted by rotating them in reverse. ■ No need for concrete chipping work or cutting of anchor bolts during removal. ■ Noise reduction. ■ Can be installed at low temperatures (minimum usable temperature -10°C). *For details, please contact us or refer to the catalog. We recommend reading the "R Anchor" and "NR Anchor" catalogs together.

The "Alonbur Coat Z-X and Z-Y Method" is a concrete surface protection material that uses acrylic rubber. Repair methods for concrete structures that utilize the features of "Alonbur Coat" include the Z-X method (prevention of deterioration + prevention of peeling) and the Z-Y method (prevention of deterioration). All standard materials used are water-based, resulting in minimal organic solvent odors or unpleasant smells, as well as reduced skin irritation commonly associated with organic materials, making it environmentally friendly for both the surrounding area and workers. The coating can be reapplied, which is effective for environmental measures and waste reduction during the next repainting. 【Features】 ■ Environmentally friendly due to the use of water-based materials ■ Repainting of the coating is possible ■ Allows moisture release from within the concrete ■ Good adhesion durability of the membrane layer to the concrete ■ Easy maintenance *For more details, please refer to the catalog or feel free to contact us.

The "NR Anchor" is an anchor bolt that uses acrylic resin and is applicable to all post-installed anchor bolts used in concrete structures. It has high viscosity and a short curing time, allowing for a reduction in construction time. During injection, there is no need for the installation and removal of pipes or seal materials, nor for resin measurement and mixing work. 【Features】 - Can be installed at low temperatures (minimum usable temperature -10°C) - Little reduction in strength even with rough mixing ratios of the two components - Prevention of construction defects such as mixing errors (uses dedicated injection equipment for automatic mixing) - Short curing time For more details, please contact the manufacturer of the R Anchor, Sanpo Co., Ltd.! *For more information, please refer to the catalog or feel free to contact us.

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.

In recent years, the installation of anti-fall devices and similar measures in seismic reinforcement work for existing bridges has been increasing. For the bracket fixing method on RC structures, adhesive post-installed anchor bolts are used, with epoxy resin-based adhesives being commonly employed. However, challenges include long curing times, failure to cure at low temperatures below 5°C, and poor adhesion on wet surfaces. To address these issues, we have developed an adhesive post-installed anchor using "acrylic resin," called "NR Anchor" and "R Anchor." (The "R Anchor" is a removable anchor bolt.) By using acrylic resin, it is possible to achieve approximately a 79% reduction in process time compared to conventional methods. ■□ We are providing technical materials that include construction achievements! □■ 【Contents (excerpt)】 - About acrylic resin - Performance verification tests - Construction achievements ■□ For more details, we will contact you from the manufacturing company of the R Anchor, "Sanpo Co., Ltd." □■ *For more details, please inquire or refer to the catalog.

The "KH-Column Joint Method" is a column-beam connection method that uses non-diaphragm connection hardware to smartly accommodate beam height differences. By simply welding the beam to the wall surface of the "KH-Column Joint," the connection is completed, making it easy to handle beams with height differences or beams installed at an angle, resulting in a clean connection that significantly reduces manufacturing labor. Products are available for square steel pipe columns ranging from 300mm to 600mm, capable of attaching beams with strengths of 400N/mm² and 490N/mm². 【Main Features】 ■ Acquired certification from the Better Living Foundation (CBL SS003-15) ■ In design, the height difference of beams can be freely set regardless of the position of other beam flanges ■ Significant reduction in welding volume and labor at steel fabrication factories ■ A substantial decrease in the number of ultrasonic flaw detection inspection points for columns ■ Easy to ensure dimensional accuracy of steel structures *For more details, please feel free to contact us.
