[Problems to be solved by the invention]

The conventional method of mounting the elevator guide rail is as described above, and since the holes for fixing the wall-side metal fittings and the rail-side metal fittings are oblong holes orthogonal to each other,
If an impact load is applied to the guide rails or rail-side metal fittings, they may be displaced within the shape range of the slotted hole in which the bolt is inserted.To prevent misalignment, increase the size of the bolt, or weld or knock in the knock pin. Since it is necessary to take measures by fixing the wall-side metal fittings and the rail-side metal fittings with each other, there are problems that the cost becomes high and the guide rail mounting accuracy becomes low.

The present invention solves the above-mentioned problems and forms holes in the wall-side metal fittings and rail-side metal fittings that have no gap with respect to the bolts so that these metal fittings can be used as a measure such as welding or knock pin driving. It is an object of the present invention to provide a method for mounting an elevator guide rail that can be fixed without a bolt and with a small size with high precision and at low cost.

[Means for solving problems]

The method for mounting the elevator guide rail according to the present invention,
Position the horizontal piece of the rail side metal fitting by overlapping it with the horizontal piece of the wall side metal fitting, and make a hole in the horizontal piece of both of the above metal fittings with the drilling device attached to the work floor suspended in the hoistway by the rope. , The bolts are inserted into the drilled holes and both horizontal pieces are tightened to fix the rail side metal fittings to the wall side metal fittings.
