Parent-child filler type Q (OF-Q) at the ABt of the RC column and S beam joint.

Parent-child filler type Q (OF-Q) at the ABt of the RC column and S beam joint.

Compatible with anchor bolt diameters M12 to M80! Base plate oversized hole filling material.

The Parent-Child Filler Q type is the only type among parent-child fillers that can transmit shear force to anchor bolts in primary and secondary designs. To achieve this, a specialized grout material called OF-Q grout is used in addition to the steel parent and child fillers. Furthermore, the shear force that can be transmitted is 70% of the allowable shear strength of the anchor bolts used; if this is exceeded, the size or number of anchor bolts must be increased to accommodate it. Applicable anchor bolts range from M12 to M80, and steel types with a tensile strength of 490 N/mm² or less can be used. There are specific conditions unique to the Parent-Child Filler Q, so for design, please refer to the "Q Type Design and Construction Standard Drawings" and the "Design Manual," and for construction, please refer to the various "Construction Manuals." *For more details, please refer to the PDF materials or feel free to contact us.

Post-construction anchor offset measures: "Parent-child filler"

Post-construction anchor offset measures: "Parent-child filler"

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.
