Abstract (en)
[origin: EP4227249A1] The present invention provides an elevator guide rail installation method in which, even if a wall-side rail bracket and a rail-side rail bracket are fixed using a drill screw, the drill screw can be driven without titling, there is no possibility that the drill screw interferes with the bracket, and the drill screw itself is not damaged. In the elevator guide rail installation method, a guide rail is fixed, via the rail-side rail bracket, to a wall-side rail bracket fixed to a wall surface in a hoistway in an elevator, and the wall-side rail bracket and the rail-side rail bracket are fastened by a drill screw. In the elevator guide rail installation method, a guide and a washer or a spacer having a diameter larger than that of a flange portion of the drill screw is installed between the drill screw and the rail-side rail bracket in a horizontal direction, and the guide is removed after the drill screw is installed, so that a gap is ensured between the rail-side rail bracket and the drill screw in the horizontal direction.
