Reinforcement of existing beam after hole cutting: "Redouble Method"
Post-extraction opening reinforcement of beams using carbon fiber and cast steel plates - 'Redouble Method'
The "Ridabble Method" is a reinforcement technique that uses carbon fiber sheets, carbon fiber plates, and specialized anchoring hardware (cast steel plates) to shear-reinforce the cut-out sections of existing beams, allowing them to achieve a load-bearing capacity equal to or greater than that of the beams before the openings. This method has obtained general evaluation certification. Unlike traditional anchoring methods using L angles or flat bars for carbon fiber sheets, this method is compact and simple, yet ensures reliable anchoring of the carbon fiber sheets. There are two types of anchoring plates: flat type and vertical type, which can also be applied to reinforcement of wall-mounted columns and T-shaped beams. 【Features】 ■ A method that has obtained general evaluation certification for opening reinforcement General evaluation (Public Interest Incorporated Foundation) Better Living CBL RC001-10 ■ Suitable for opening reinforcement due to equipment renewal ■ Allows for pseudo-closed reinforcement through the use of anchoring hardware ■ Applicable to underground beams as well *For more details, please refer to the PDF materials or feel free to contact us.
