PROBLEM TO BE SOLVED: To provide stairs and an assembly method of the stairs, capable of improving workability.SOLUTION: An operator first installs a first corbel 311 in a skeleton A1, and installs a second corbel 312 on the skeleton A1 later while engaging with the first corbel 311. Thus, when installing the second corbel 312, for example, positioning work in the height direction is simplified. The operator also fits a corbel installing part 612 of a first fixture 61 in a fitting-in recess 411 of the first corbel 311, and is installed in the first corbel 311. Positioning to the first corbel 311 of the first fixture 61 is naturally executed when fitting the corbel installing part 612 in the fitting-in recess 411. That is, positioning work to the first corbel 311 of the first fixture 61 is simplified. Thus, positioning work to the skeleton A1 of the first fixture 61 can be simplified. As a result of this, workability of stairs 11 can be improved. |
