This is a list of "NR Anchors" and "R Anchors" that can be installed even at low temperatures of -10℃.
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 process 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) ■ Minimal strength reduction even with rough mixing ratios of the two components ■ Prevents construction defects such as mixing errors ■ Short curing time The "R Anchor" is a post-installed anchor bolt that can be removed after use, such as for temporary materials. It has a special coating on the embedded part of the anchor bolt, allowing it to be removed by applying reverse rotation with a wrench after use. 【Features】 ■ Can be removed by rotating the bolt in reverse. ■ No need for concrete chipping or cutting of the anchor bolt during removal ■ Noise reduction ■ Can be installed at low temperatures (minimum usable temperature -10°C) *For more detailed information, please contact the manufacturer of the R Anchor, Sanpo Co., Ltd.!
