Abstract:
An elevation-type stair structure comprises: a first stair module, including plural first treads and a first wall surface having a first door and a second door; a second stair module, including plural second treads and a second wall surface having a third door and a fourth door; and an elevator module, enabling the first stair module or the second stair module to be ascended or descended, when the second stair module is ascended for being above a location defined at one side of the first stair module, the second door is aligned with the third door, when the second stair module is descended for being below a location defined at one side of the first stair module, the first door is aligned with the fourth door. Accordingly, a user can walk through the first stair module and the second stair module then return to an original location.
