Joint structure of reinforced concrete column, steel column and steel beam

摘要

PROBLEM TO BE SOLVED: To provide a reinforced concrete column/steel column/steel beam joint structure in which even when a steel column as an upper floor column has width thicker than a steel beam on which the steel column is placed, the upper floor column can be joined to the steel beam without causing any trouble in stress transmission in a building skeleton in which the lower floor column is constituted of the reinforced concrete column, and a beam is constituted of the steel beam.SOLUTION: In a joint structure in which the upper end of a lower floor column constituted of a reinforced concrete column 1 is jointed to the lower end of an upper floor column constituted of a steel beam 3 and a steel column 2 having a diameter smaller than the lower floor column, and larger than the width of the steel beam 3, the steel beam 3 is embedded in the upper end of the lower floor column, and an upper floor column support plate 4 in a standing posture is provided on an upper surface in a plane range embedded in the reinforced concrete column 1 of the steel beam 3. A base plate 5 on which the lower end face of the upper floor column is placed on the whole is provided on the upper floor column support plate 4. A bending reinforcement body 6 for reinforcing the bending of the upper floor column is provided in the periphery of the lower end of the upper floor column.SELECTED DRAWING: Figure 2
