And a connecting body 14 for connecting.

The first gauge 12 is a car guide rail 4
a first gauge body 15 extending in the direction of the gap between the first gauge body 15 and the first and second engagement plates 16 and 17 fixed to both ends of the first gauge body 15; have. Notch grooves 16a, 17a engaging with the piano wires 6a, 6b are formed in the first and second engagement plates 16, 17, respectively.
First rail engaging portions 16b and 17b that engage with the car guide rails 4a and 4b are provided.

The second gauge 13 has a second gauge body 18 extending in the direction of the space between the counterweight guide rails 5a and 5b (the left-right direction in FIG. 1), and is fixed to both ends of the second gauge body 18. Third and fourth engagement plates 19, 20
And The third and fourth engaging plates 19, 20 are provided with second rail engaging portions 19a, 20a which engage with the counterweight guide rails 5a, 5b.

The connecting body 14 includes a first sub-gauge 21 for connecting one end of the first gauge 12 and one end of the second gauge 13, a second end of the first gauge 12 and a second gauge. 13 has a second sub-gauge 22 that connects the other end of the first gauge 12 and a third sub-gauge 23 that connects one end of the first gauge 12 and the other end of the second gauge 13.

Bolt pins 24 are screwed to both ends of the first and second gauges 12, 13, respectively. The ends of the first to third sub-gauges 21 to 23 are fitted to the tip of the bolt pin 24.

Next, the centering operation will be described. The guide rail centering device 11 is installed horizontally in the hoistway 1,
By inserting the piano wires 6a, 6b into the notch grooves 16a, 17a and engaging the car guide rails 4a, 4b with the first rail engaging portions 16b, 17b, the car guides for the piano wires 6a, 6b. The rails 4a and 4b are positioned, and the car guide rails 4a and 4b are centered.

In this state, the counterweight guide rails 5a, 5b are engaged with the second rail engaging portions 19a, 20a, so that the piano wires 6a, 6b are
The counterweight guide rails 5a and 5b are positioned via the connecting body 14, and the counterweight guide rails 5a and 5b are centered.

Normally, a plurality of guide rails 4a, 4b, 5a, 5b are spliced in the height direction of the hoistway 1 while moving the guide rail centering device 11 upward along the hoistway 1, Centering is performed sequentially from bottom to top. The centered guide rails 4a, 4b, 5a, 5b are firmly fixed to the wall of the hoistway 1.

In such a guide rail centering device 11, the position of the second gauge 13 with respect to the first gauge 12 is fixed by the connecting member 14, so that the four piano wires 6a and 6b alone Book guide rails 4a, 4b,
Centering of 5a and 5b can be performed. Therefore, the centering work can be simplified, and the work efficiency can be improved. Also, since only two piano wires 6a and 6b are required, the cost is reduced, and the labor for re-stretching in the event that the piano wires 6a and 6b are cut is reduced.

A first sub-gauge 21 for connecting one end of the first gauge 12 and one end of the second gauge 13 is provided.
A second sub-gauge 22 for connecting the other end of the first gauge 12 to the other end of the second gauge 13; one end of the first gauge 12 and the other end of the second gauge 13 And the third sub-gauge 23 that connects the three sub-gauges is used.
The position of the second gauge 13 with respect to the first gauge 12 can be fixed.

Further, the first and second gauges 12, 13
And the connecting body 14 are connected to the bolt pins 24 with the sub gauges 21 to
Since they are connected by fitting with each other, they can be easily attached and detached. Accordingly, a plurality of first gauges 12 having different sizes, a plurality of second gauges 13 having different sizes,
A plurality of connectors 14 having different sizes are manufactured in advance, and the first gauge 12, the second gauge 13 and the connector 1
