Parent-child filler

Parent-child filler

Avoid performance-related issues such as the previously conducted adjustments to the platform and re-drilling of base plate holes!

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 architectural components of the 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.

Parent-Child Filler Type K (OF-K)

Parent-Child Filler Type K (OF-K)

"Stair-Specific K Type" Anchor Bolt Diameter M16/M20 Compatible! Base Plate Oversized Hole Filling Material *For Stair Use Only*

The parent-child filler type K is a parent-child filler specifically for stairs. The applicable ABt is only two types: M16 and M20. It is characterized by a larger installation tolerance range for ABt compared to OF-L (OF-S), approximately double the value. The design condition stipulates that no tensile force should be applied to ABt. Shear force is treated similarly to OF-S. There are specific conditions unique to the parent-child filler K, so please refer to the "K Type Design and Construction Standard Drawings" and "Design Manual." *For more details, please refer to the PDF materials or feel free to contact us.*

Parent-Child Filler Type S (OF-S)

Anchor bolt diameter M12 and M52 to M80 compatible! Base plate oversized hole filling material.

The parent-child filler type S has the same functions as type L, but it cannot transmit the shear force acting on the base of the column to the bolts in the primary and secondary design. The applicable anchor bolts range from M52 to M80, and steel grades with a tensile strength of 490 N/mm² or less can be used. There are specific conditions unique to the parent-child filler type S, so please refer to the "S Type Design and Construction Standard Drawings" and the "Design Manual." *For more details, please refer to the PDF materials or feel free to contact us.*

No need for anchor bolt base adjustment - "Parent-Child Filler Q Type (OF-Q)"

No need for anchor bolt base adjustment - "Parent-Child Filler Q Type (OF-Q)"

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 design. To achieve this, a dedicated 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, so if this is exceeded, the size or number of anchor bolts must be increased to accommodate it. The 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 "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.
