Parent-child filler at the column-beam joint

Avoid performance-related issues such as the previously conducted adjustments to the table and re-drilling of holes in the base plate! *Sample available for provision.

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, it eliminates the need for corrective measures such as "straightening the anchor bolts" or "enlarging the base plate holes," allowing for the precise installation of steel columns 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) capable of transmitting shear forces to the anchor bolts. *For more details, please download the PDF or contact us.
