Avoid performance-related issues such as re-leveling and re-drilling holes in base plates that have been carried out in some areas until now! *Sample available upon request.
The "parent-child filler" consists of two steel components of different sizes, each with an eccentric hole. By using this in the base of steel columns, there is no need for corrective measures such as "straightening the anchor bolts" or "enlarging the base plate holes," allowing for the installation of steel columns with precision without damaging the important building components of anchor bolts and base plates. The corresponding anchor bolt sizes range from M12 to M80. 【Four Types】 ■ Parent-child filler L type (OF-L) with performance equivalent to exposed column bases as specified in the Ministry of Construction Notification No. 1456 of Heisei 12. ■ Parent-child filler S type (OF-S) compatible with large diameters M52 to M80. ■ Parent-child filler K type (OF-K) specifically for stairs. ■ Parent-child filler Q type (OF-Q) that can transmit shear forces to the anchor bolts. *For more details, please download the PDF or contact us.
