Developed post-installed ceramic anchoring shear reinforcement bars! Achieving excellent shear reinforcement efficiency.
It has been pointed out that some concrete structures designed according to old seismic standards may lack sufficient shear strength and ductility of components when subjected to seismic forces equivalent to level 2 seismic motions that should be considered under current seismic standards. The "Ceramic Cap Bar (CCb) Method" allows for the placement of ceramic anchorage bodies, which have excellent corrosion resistance, near the surface of the concrete, ensuring the durability of the anchorage while achieving excellent shear reinforcement efficiency. The diameters of the threaded rebar correspond to D13, D16, D19, D22, D25, D29, and D32. 【Features】 ■ High shear reinforcement efficiency ■ High durability ■ High workability and quality ■ Easy installation even in narrow spaces ■ Selection of types according to the condition of existing structures ■ Usable in corrosive environments 【Certification Information】 ■ Acquired construction technology examination certification from the Public Interest Incorporated Foundation Civil Engineering Research Institute (Certification No. 0811) ■ NETIS registration KT-120076-A (registration expired) ■ June 2020, awarded the Civil Engineering Society Technology Development Award ■ Tokyo Metropolitan Government New Technology Information Database (Registration No. 1801010) ■ Agricultural and Rural Development Private Technology Information Database (Registration No. 1070)

basic information
■High shear reinforcement efficiency: Since the anchoring body is made of fine ceramics, it can be placed near the concrete surface, allowing for high shear reinforcement effectiveness. ■High durability: The ceramics that make up the anchoring body have excellent corrosion resistance, ensuring long-term resistance to corrosion of the reinforcement even when the ends of the shear reinforcement bars are placed near the concrete surface. ■High workability and quality: It can be easily constructed without large equipment even in narrow spaces or complex areas, and stable quality work can be easily performed even in narrow spaces where the length of the inserted ceramic cap bar cannot be secured. *For more details, please refer to the related links or feel free to contact us.
