Once positioned at the set dimension L ₁ , each counterweight rail template 20 is fixed to the machine room floor 2 by the anchor bolt 21 and the nut 21a. Then the piano wire
One end of 8b is fixed to the template 20 with a screw 22, and the other end side is hung down from the hole 3 into the hoistway through the corner of the corner of the corner 20a to be used for installation of the counterweight rail.

The elevator installation apparatus according to the present embodiment has a pair of substantially rectangular template plates 20 positioned linearly symmetrically on the two floors of the machine room floor to perform centering upon installation of the elevator. In the template 20, the corner portion 20a formed by cutting out at one corner portion for hanging and aligning the centering piano wire, and the corner portion 20a on two sides not adjacent to the corner portion 20a. Corresponding to, a side that is in a straight line with one side of the corner portion 20a formed by the notch for alignment, for example, a right edge 20a ₁ and an edge 20b ₁ , a right edge 20a ₂ and an edge 20b ₁ are in a straight line state. It is provided with a cutout portion 20b formed by cutting out so as to have a certain side, and a plurality of fixing holes 20c formed for fixing to the surface of the machine room floor 2.

Therefore, since the pair of centering templates 20 having the same shape can be mounted on two floors of a predetermined machine room floor where the installation of the equipment in the tower is centered, the car rail for each elevator model can be mounted. And even if the interval of the counterweight rail changes, it can be shared by one type of template, and even if the model of the equipment in the tower that is centered for installation is different from the car rail, counterweight, etc., it has a single shape. You just need a board.

For this reason, many types of templates corresponding to the model of the elevator as in the past are not required, and the templates can be provided at low cost. In addition, the template 20 used for centering the installation of the equipment in each tower
Are all installed on the floor of the machine room.
Even if 20 is provided, it can be installed on the hoisting machine on the machine base, and accordingly, the scaffold-less construction method can be applied to the installation of the elevator.

Needless to say, the centering procedure for elevator installation in the present invention is not limited to that shown in the above embodiment.

[Effects of the Invention] As described above, according to the elevator installation device of the present invention, one pair of template plates is used, and it corresponds to a predetermined position where in-tower equipment such as a car rail and a counterweight rail is installed. However, they are positioned symmetrically on the floor of the machine room, and this pair of templates can be used for centering the installation of the corresponding in-tower equipment. Further, the corner portion in which one corner portion of the square plate-shaped template is cut out at a right angle to form the entering corner portion can hold and position the centering piano wire depending on the corner portion. A notch is formed on two sides that are not adjacent to the corner so as to have a straight side with one side of the corner that is notched for alignment and that corresponds to the corner. From
The relationship between the templates becomes clear.

Further, a notch for alignment corresponding to the corner portion is formed on two sides not adjacent to the corner portion, and a plurality of mounting holes for mounting on the floor surface of the machine room are drilled. Since one pair of plates is used as a template for installation centering of the equipment in the tower, if one type of template is formed, this can be used for all the installation centering templates. At the same time, it can accommodate any size of piano wire spacing, can be shared by all elevator models, and can provide templates at low cost.

Further, since the template is installed on the floor of the machine room, it becomes possible to support a scaffold-less construction method, and there is an effect that installation work can be facilitated.

Therefore, there is an effect that positioning between the template plates is easy, the method can be applied to the scaffold-less construction method, and the change of the spacing between the guide rails of the car and the counterweight can be dealt with.
