PROBLEM TO BE SOLVED: To provide a reinforcement structure of a hybrid beam having an installation hole, which can improve reinforcement workability of a reinforced concrete beam part through which an installation hole is penetrated horizontally and which is advantageous to reducing a degree of damage caused in the earthquake.SOLUTION: An installation hole reinforcement part 22 is configured by including mesh reinforcement 24. The mesh reinforcement 24 includes side surface parts 2404 on both sides, an upper surface part 2404 and a lower surface part 2406. The side surface parts 2402 on both sides have holes 2410 formed therein, each of which matches the installation hole 20, and are arranged while being respectively sandwiched between upper and lower beam main reinforcement bars 14 and vertically extending horizontal reinforcement bars 16. The upper surface part 2404 and the lower surface part 2406 are arranged while being respectively sandwiched between the upper and lower beam main reinforcement bars 14 and horizontally extending upper and lower horizontal reinforcement bars 16. |
