Then, in order to prevent the rail-side metal fitting 2 from being displaced with respect to the wall-side metal fitting 7, the rail-side metal fitting 2 and the wall-side metal fitting 7 are fixed by welding 16 the horizontal piece 2c and the horizontal piece 7c.

[Problems to be solved by the invention]

In the conventional method of mounting the elevator guide rail as described above, the long holes 7b, 2b through which the bolts 12 are inserted are formed in the wall-side metal fitting 7 and the rail-side metal fitting 2 so as to be orthogonal to each other. For this reason, for example, when an earthquake occurs, the bolts 12 may cause the bolts 12 to be elongated holes 7b, 2b due to the earthquake load acting on the guide rail 1.
There is a risk of deviation within the shape range of. When such a phenomenon occurs, the wall-side metal fitting 7 and the rail-side metal fitting 2 are displaced from each other. Therefore, in order to prevent the displacement, the horizontal pieces 7c and 2c are fixed by welding.

On the other hand, in recent years, new construction work for removing elevators from existing building has increased, but in these existing building, fire use is often restricted to prevent fire. Therefore, there are many sites where welding work cannot be performed, and there is a problem that the above method cannot be adopted at these sites.

Further, even when welding is possible, since the rail-side metal fitting 2 and the wall-side metal fitting 7 are deformed by the welding heat generated at the time of welding, the mounting accuracy of the guide rail 1 is changed, and eventually the riding comfort of the elevator is deteriorated. There was a point.

The present invention has been made to solve the above problems, and provides an elevator guide rail mounting method capable of preventing the rail-side metal fittings and the wall-side metal fittings from being displaced without performing heat-generating welding work. Obtainable.

[Means for solving problems]

An elevator guide rail mounting method according to the present invention includes a horizontal piece and a vertical piece perpendicular to the horizontal piece, which is fastened to a hoistway wall, and has a horizontal piece and a vertical piece perpendicular to the hoistway wall. Fasten the guide rail to the vertical piece of the rail-side metal fitting, then position the horizontal piece of the rail-side metal fitting on the horizontal piece of the wall-side metal fitting, position it, and tighten the bolts inserted into the long holes of each horizontal piece. After the rail-side metal fitting is fastened to the wall-side metal fitting, the one horizontal piece bites into the other horizontal piece to form a dowel.

[Work]

In the present invention, mechanical pressure is applied to each horizontal piece in a normal temperature state, and one horizontal piece engages with the other horizontal piece to form a dowel, so that the horizontal pieces are fixed to each other.

Therefore, even if a load is applied to the guide rail when an earthquake occurs, the rail-side metal fitting and the wall-side metal fitting are not displaced.

〔Example〕

An embodiment of the present invention will be described in detail below with reference to FIGS. 1 and 2.

In this embodiment, the same or equivalent members and parts as those in the above-mentioned conventional example are designated by the same reference numerals, and the description thereof will be omitted.

In the method for mounting the elevator guide rail according to the present invention, the anchor rail 8 is fixed to the hoistway wall 11 at a position suitable for fixing the guide rail 1, and the like.
The anchor bolt 8 is fitted into the elongated hole 7a of the vertical piece 7d of the wall-side metal fitting 7, and the vertical piece 7d is fixed to the hoistway wall 11 using the spring washer, the flat washer 10 and the nut 9.

Next, the bolt 4 inserted into the rail clip 3 is fitted into the hole 2a provided in the vertical piece 2d of the rail side metal fitting 2 and the guide rail 1 is inserted through the rail clip 3 into the vertical piece 2d using the spring washer 6 and the nut 5. Tighten. And the horizontal piece 7c of the wall side metal fitting 7
And the horizontal piece 2c of the rail side metal fitting 2 are overlapped, and the horizontal piece 7
Insert the bolt 12 into the long holes 7b, 2b provided in c, 2c, temporarily fix the horizontal pieces 7c, 2 using spring washers, plain washers, and nuts not shown, and measure from the reference line 15 to the guide rail 1. Take out A and B and further tighten the bolt 12.

Next, a concave surface 2e and a convex dowel 2f are formed on the horizontal piece 2c by a not-shown press or the like, and the horizontal piece 7c has a concave surface 7e into which the convex dowel 2f bites and a convex dowel 7f corresponding to the concave surface 7e. The forming dowel 20 is formed. The dowel projecting 20 is performed on both left and right sides of the horizontal piece 2c.

In the above elevator guide rail mounting method,
Since the convex dowel 2f of the horizontal piece 2c bites into the concave surface 7e of the horizontal piece 7c, the horizontal piece 2c and the horizontal piece 7c are strongly emphasized to each other.

Therefore, even if the load when the earthquake occurs acts on the guide rail 1, the rail-side metal fitting 2 and the wall-side metal fitting 7 are not displaced.

〔The invention's effect〕

As described above, according to the present invention, after the rail-side metal fittings are fastened to the wall-side metal fittings, one horizontal piece engages with the other horizontal piece to form a dowel, whereby the horizontal pieces are firmly fixed to each other. Therefore, even if the earthquake load of the earthquake generator acts on the guide rail, the rail-side metal fittings and the wall-side metal fittings will not be displaced from each other. Moreover, since welding work is not required, it can be used even in an existing building where the use of fire is restricted. Further, since the member is not deformed by the heat of welding, the guide rail can be attached at a predetermined position with high accuracy. Therefore, there is an effect that the riding comfort of the elevator is not deteriorated. Moreover, since the construction can be performed only by mechanical work, the construction can be simplified.
