Japanese Patent JP7162492

B2

To provide a technique capable of improving workability for filling concrete in a CFT column having a branch structure.SOLUTION: A concrete filling method in branch column sections where a CFT column is branched into a plurality of branches from a joint part between the CFT column and a beam to a lower direction comprises: an insertion step of inserting a concrete filling pipe into a concrete press-in cavity through a filling pipe insertion hole after the concrete press-in cavity is installed below a lower diaphragm of the joint part between the CFT column and the beam and at a place between the branch column sections in such a way as to be communicatively connected through the filling pipe insertion hole opened in the lower diaphragm as well as to be communicatively connected through a side surface press-in hole opened on each of steel pipes forming each of the branch column sections; and a press-in step of simultaneously press-filling concrete pumped into the concrete press-in cavity to each of the branch column sections from the side surface press-in hole after pumping concrete into the concrete press-in cavity from a tip end part of the concrete filling pipe.SELECTED DRAWING: Figure 11
