Staircase RC column and S beam joint "Parent-Child Filler K Type (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 twice the value. As a design condition, it is specified that no tensile force should be applied to ABt. Shear force is treated in the same manner as 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 the "Design Manual." *For more details, please refer to the PDF materials or feel free to contact us.*
