REFERENCE POSITION SETTING METHOD OF ELEVATOR MATERIAL, INSTALLATION METHOD OF ELEVATOR MATERIAL, REFERENCE POSITION SETTING DEVICE OF ELEVATOR MATERIAL, AND REFERENCE POSITION SETTING SYSTEM

摘要

To provide a reference position setting method of an elevator material, an installation method of an elevator material, a reference position setting device of an elevator material, and a reference position setting system by which an elevator material can be easily mounted on a hoistway of an elevator highly precisely.SOLUTION: The reference position setting method for setting a reference position of an elevator material installed in an elevator hoistway by using two or more laser irradiators for emitting laser visible light, includes a laser irradiator position specification step of specifying a position of each laser irradiator by aligning the laser visible light with a building ink and a marking step of irradiating an installation position of the elevator material with the laser visible light from each laser irradiator whose position is specified so that an intersection of the laser visible light is marked as a reference position of the elevator material.SELECTED DRAWING: Figure 1
