For example, there is no support hole 1b for supporting the horizontal support 62 in the inner wall 1a of the elevator hoistway 1, and as a result, when the horizontal support 62 cannot be used, the horizontal The horizontal beam 24 of the main frame 20 is supported on the elevator hoistway 1 in place of the support 62 .

In some cases, the support support 70 is installed at the same time as the horizontal supports 62, and the horizontal beam 24 of the main frame 20 together with the horizontal supports 62 is moved to the elevator hoistway (1). can be supported at the same time.

According to the scaffolding apparatus for installing an elevator of the present invention having such a configuration, since it has a structure including a scaffolding support 10 that can be supported by supporting the scaffold 3a, if the scaffolding support 10 is used, the scaffold 3a of the elevator hoistway (1) can be installed directly at a desired height.

In addition, since the scaffold 3a can be directly installed at a desired height among the parts of the elevator hoistway 1, the scaffold 3a is not installed from the floor of the elevator hoistway 1 to the desired height as in the prior art. do.

In addition, since the scaffold 3a can be installed directly at the desired height without installing one by one from the bottom of the elevator hoistway 1 to the desired height, the installation and removal of the scaffold 3a can be significantly reduced Through this, it is possible to significantly improve the time, cost, and convenience of work that occur during the installation and removal of the scaffold 3a.

In addition, since the number of man-hours for installation and removal of the scaffold 3a can be significantly reduced, it is possible to remarkably improve the fear of safety accidents occurring during installation and removal of the scaffold 3a.
