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 special 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.
