BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a maintenance ladder used for maintenance such as cleaning and repair work of each roof in a retractable building in which an indoor facility can be used as an outdoor facility.

[0002]

2. Description of the Related Art Opening / closing buildings are constructed by nesting a fixed roof and a movable roof. On a good weather day, the movable roof was moved to the fixed roof side, and the exhibition facility, an indoor facility,
Various facilities such as a meeting place, an event place, or a sports facility such as a pool or a tennis court are opened to the outside. On the other hand, on bad weather days such as rainy weather and strong wind, the movable roof moved from the fixed roof side to the opposite side can be returned to the indoor facility, so it is used as an all-weather facility.

[0003] Maintenance work such as cleaning and repair work in the above-mentioned opening and closing type building is performed on a ladder leaning on a roof, working within reach, moving down from the ladder and moving with the ladder, He repeatedly leaned on the next place.

[0004]

However, the above method has the following problems that must be solved. (1) When changing the ladder, the worker must move with the ladder, which is troublesome. (2) Since both ends of the ladder are not fixed to the roof side and the ground side, the ladder is unstable, and the ladder is likely to fall down, which is dangerous.

[0005]

SUMMARY OF THE INVENTION According to the present invention, in view of the above-mentioned prior art, the maintenance of a standing ladder is troublesome and dangerous. By providing a movable ladder that is movable and arranging a fixed ladder along at least one outer end face of the roof other than the innermost one, the outermost roof can be provided with a scaffold that is movable. Then, maintenance is performed by sequentially moving the moving ladder, and the inner roof is moved or fixed to the outermost end of the outermost roof, or fixed on the outer roof to be maintained. The above problem is solved by performing maintenance by moving and fixing the roof using a ladder as a scaffold so that all roofs can be maintained. In addition, the innermost roof is maintained by moving the roof using the fixed ladder of the outer roof as a scaffold, so that at least the driving means of the fixed ladder for the innermost roof is not provided. Make the inner roof accessible for maintenance.
