<P>PROBLEM TO BE SOLVED: To provide a joint structure between a steel frame beam and a concrete column that enable column concrete and floor slab concrete to be securely and discriminatingly cast on the site, and facilitates manufacture of a closing plate. <P>SOLUTION: A joint part 4 between a steel frame beam 2 and a reinforced concrete column (concrete column) 3 is provided with a closing plate 5 which is formed to a height equal to the depth of a steel beam 2, and surrounds the reinforced concrete column 3. An L-sectioned steel material 7 including a perpendicular part 8 which extends perpendicularly upward along an outer peripheral surface of the reinforced concrete column 3 and a horizontal part 9 which connects with a lower-end part 8b of the perpendicular part 8 and extends horizontally to outside the reinforced concrete column 3 is joined with an upper-end part 2a of the steel beam 2 and an upper-end part 5a of the closing plate 5, and an upper-end part 7a of the steel material 7 reaches a top end 11a of a floor slab 11 installed above the steel beam 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
