CONCRETE FILLING METHOD IN CFT COLUMN

摘要

To provide a technique to fill concrete densely and tightly in a lower surface of a diaphragm at a joint part between a CFT column and a beam when filling concrete in the CFT column.SOLUTION: A concrete filling method in a CFT column is to fill concrete from a lower side of a diaphragm after forming a filling hole and an air bleed hole for the concrete in the diaphragm at a joint part between a CFT column and a beam where the CFT column is connected with the beam as well as a cylindrical erected part erected from an upper surface of the diaphragm on an edge part of the filling hole.SELECTED DRAWING: Figure 7
