PROBLEM TO BE SOLVED: To provide a joint material between a column and a flat slab, having excellent filling property of concrete from the steel pipe or steel pipe concrete column to the flat slab, capable of increasing joint strength and rigidity, and ensuring the filling property of concrete to a diaphragm even when a span between columns is large, to improve its workability and reliability.SOLUTION: A joint material between a column and a flat slab for joining the steel pipe or steel pipe concrete column 12 to the flat slab 10 made of reinforced concrete includes: a pair of upper and lower diaphragms 16, 18 arranged at a predetermined interval at a forming position of the flat slab 10 around the column 12, cantilever beams 22 radially arranged from the diaphragms 16, 18 in directions toward an outer periphery; and outer peripheral beams 20 arranged so as to connect the tips of the cantilever beams 22 to each other. |
