Contributing to significant labor savings! A column-beam joint method that achieves a clean joint.
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.
