Wide range of application opening reinforcement hardware
In recent years, the application of RC structures in mid-rise and even high-rise buildings has expanded, leading to advancements in the high strength of structural materials, namely concrete and reinforcing steel. This development has created a demand for opening reinforcement hardware with a wide range of applications, from normal strength to high strength structural materials. The "Daiyaren NS" developed this time is a high-strength opening reinforcement hardware that meets these expectations, with an application range of Fc=21N/mm2 to 70N/mm2 and SD295A to 1275 grade high-strength reinforcing bars. In the design of this opening reinforcement hardware, not only the strength of the reinforcement hardware is considered, but also the amount of reinforcement, or reinforcement rigidity, is taken into account to ensure reinforcement effectiveness from normal strength concrete to high-strength concrete. Additionally, the "Daiyaren NS" can also be used as shear reinforcement hardware for SRC beam openings.
