"Tsuitaro" is a mechanical joint that eliminates on-site welding of piles. After fitting the inner joint, which is welded at the factory to the lower end of the upper pile, onto the outer joint, which is welded at the factory to the upper end of the lower pile, a pin is inserted to join them together. To prevent the pin from moving or falling out during construction, a pin fixing screw is used to secure the pin. 【Features】 ■ No need for welding work on-site, allowing for easy connections ■ High strength and reliability ■ Simple construction management ■ Compatible with a wide range of pile diameters ■ Removable *For more details, please refer to the PDF document or feel free to contact us.
