Description

[Detailed Description of the Invention] This invention relates to an elevator guide rail mounting device, and is particularly suitable for large-capacity elevators.

Normally, the installation device for the guide rail of an elevator involves drilling multiple holes in the hoistway wall after constructing the hoistway, driving anchor bolts into each of the holes, attaching a rail bracket using the anchor bolts, and then attaching the rail bracket to the rail bracket. A guide rail is attached to the

However, the above-mentioned device is not suitable for large-capacity elevators because of problems with the strength of the anchor bolts, and conventionally, devices as shown in FIGS. 1 and 2 have been employed.

In the figure, 1 is a hoistway wall, 2 is a building beam made of steel, etc. embedded in the hoistway wall 1, 3 is a threaded end that protrudes into the hoistway, and the other end is a mounting bracket 4. The anchor bolts are fixed to the building beams 2 at appropriate intervals by welding or the like through the anchor bolts, and are made of round steel or the like embedded in the hoistway wall 1.

Reference numeral 5 denotes a rail bracket having a U-shaped cross section, both ends of which are bent outward parallel to the bottom surface, and each of these bent surfaces is provided with a through hole through which the threaded portion of the anchor bolt 3 is inserted. It is fastened to the anchor bolt 3 with a nut 7 and washer 8 with a runner 6 interposed between them.

Reference numeral 9 denotes a well-known guide rail for guiding the car case or counterweight, and is fastened to the bottom surface of the rail bracket 5 with a plurality of bolts 10, nuts 11 and washers 12.

After the anchor bolts 3 are fixed to the building beams 2 by welding or the like via the mounting brackets 4, concrete or the like is cast, and the anchor bolts 3 are buried in the hoistway wall 1 with threaded portions remaining.

That is, the guide rail 9 is fastened to the hoistway wall 1 by a plurality of anchor bolts 3 and the like via the rail bracket 5 and the like.

The guide rail 9 is fastened to the hoistway wall 1 at a plurality of locations at appropriate intervals along the longitudinal direction of the hoistway.

As described above, since the installation of each anchor bolt 3 is done on-site, work efficiency is poor, and the pitch dimension P1 between the anchor bolts 3. P2P3 and guide rail 9
The accuracy of the spacing between the fastening points was poor.

After constructing the hoistway wall 1, measure the pitch dimensions P1 * P2 and P3 between the anchor bolts 3 and the distance between the fastening points of the guide rail 9, and then thread the anchor bolts 3. It was necessary to make a through hole in the rail bracket 5 and to make a hole in the guide rail 9 for the part to pass through.

Therefore, the rail brackets 5 are not compatible with each other, which inevitably increases the cost and increases the number of days required to install the casing.

This invention solves the above-mentioned drawbacks. By integrating a plurality of anchor bolts 3 with a connecting body and fixing it to the building beam 2, the pitch dimension between the anchor bolts 3 and the distance between the connecting bodies can be adjusted. It is an object of the present invention to provide a guide rail mounting device that improves accuracy, provides mutual compatibility between rail brackets 5, and allows guide rails 9 to be processed in advance, thereby significantly reducing the number of days required for installation. It is something to do.

An embodiment of this invention will be described below with reference to FIGS. 3 and 4.

In the figure, parts that are the same or equivalent to those of the above-mentioned conventional device are given the same reference numerals, and 13 is a connecting body configured to integrate a plurality of anchor bolts 3, with both ends having a U-shaped cross section. The anchor bolts 3 are bent outward parallel to the bottom surface, and each anchor bolt 3 is attached to the bottom surface with a pitch dimension of P 1.
* A connecting plate 14 with through holes drilled at intervals of P2 e P3, and a connecting piece 15 that abuts the buried end of each anchor bolt 3 and fixes the anchor bolts 3 to each other by welding or the like. It is made up of.

That is, the anchor bolts 3 are accurately integrated by welding or the like at intervals of pitch dimension P1*P2tP3 via the connecting plate 14 and the connecting piece 15).
The connecting piece 15 is fixed to the building beam 2 by welding or the like via the mounting piece 17, and then concrete or the like is poured and the anchor bolt 3 is buried in the hoistway wall 1, leaving the threaded part. has been done.

These integral components of the connecting body 13 and the anchor bolts 3 are arranged at a plurality of locations at appropriate intervals along the longitudinal direction of the hoistway.

Therefore, the pitch dimension P1 between the anchor bolts 3
e P 2 * P 3 and the spacing between the connecting bodies 13 are accurate.

As a result, the rail bracket 5 and the liner 6 are compatible and can be manufactured in advance.

Further, the guide rail 9 can also be processed in advance.

In addition, in the above embodiment, each anchor bolt 3 is integrated through the connecting plate 14 and the connecting piece 15, but the mutual pitch dimension of the anchor bolts 3 P 1 s P 2 s
Similar effects can be expected with any shape as long as it is constructed so that the distance P3 can be maintained accurately.

As explained above, this invention maintains the distance between multiple anchor bolts at a predetermined dimension and embeds a connecting body that integrally connects them in the hoistway wall, thereby reducing the pitch dimension between the anchor bolts. Since the guide rails can be processed in advance to ensure accuracy and the rail brackets can be interchanged, we have realized a guide rail mounting device for large-capacity elevators that is inexpensive and shortens the installation time. It is something to do.
