4 and 5 show a conventional elevator guide rail mounting device disclosed in, for example, Japanese Utility Model Application Publication No. 55-11996. In Figures 4 and 5, 1 is a guide rail;
2 is an angle-shaped rail side metal fitting having a horizontal piece 2d and a vertical piece 2e perpendicular thereto, and a hole 2a in the vertical piece 2e.
However, elongated holes 2b for adjusting the position of the guide rail 1 in the depth direction are formed in each of the horizontal pieces 2d. 3 is a rail clip, 4 is a bolt that is inserted through the rail clip 3 and the vertical piece 2e of the rail side metal fitting 2, 5 is a nut, and 6 is a spring washer. It is fixed to piece 2e. Reference numeral 7 designates an angled wall side metal fitting that has a horizontal piece 7d and a vertical piece 7e perpendicular thereto, and constitutes a rail bracket together with the rail side metal fitting 2. The vertical piece 7e has a long length 7a corresponding to the misalignment of the anchor bolt 8. , an elongated length 7b for adjusting the position of the guide rail 1 in the left-right direction is formed on each of the horizontal pieces 7d. 9 is a nut, 10 is a spring washer, and these and the anchor bolt 8 allow the vertical piece 7e of the wall side fitting 7 to be attached to the hoistway wall 11.
is fixed. 12 is a long hole 2b. The bolt 7b is pushed through, 13 is a nut, and 114 is a spring washer, and these parts connect the horizontal piece 7d of the wall side fitting 7 and the rail side metal fitting 2 superimposed on this horizontal piece 7d. The horizontal piece 2d is tightened and fixed. A reference line 15 is a piano wire for centering the guide rail 1, and the reference line 15 is perpendicularly stretched from the top of the hoistway to the pit for each guide rail. 16 is a weld for preventing the rail side metal fitting 2 and the wall side metal fitting 7 from shifting. By the way, the guide rail 1 is erected vertically with high accuracy with reference to the reference line 15, but since the flatness of the hoistway wall 11 to which the guide rail 1 is attached is not very high, the rail side of the hoistway wall 11 and the guide rail 1 is The dimension H (see FIG. 4) between the vertical piece 2e of the metal fitting 2 and the mounting surface is not constant. For this reason, the bolt 4 is inserted through the rail clip 3.
The rail side metal fitting 2 fixed to the guide rail 1 by the anchor bolt 8 and the wall side metal fitting 7 fixed to the hoistway wall 11 by the anchor bolt 8 constitute a rail bracket, and the horizontal piece 2d of the rail side metal fitting 2 and the wall side metal fitting The bolt 1 is inserted into the elongated hole 2b and elongated hole 7b formed perpendicularly to each other in the horizontal piece 7d of No.7.

Fluctuations in the dimension H are adjusted by the elongated holes 2b and 7b. However, when a very large force is applied to the rail bracket during an earthquake or the like, the rail-side metal fitting 2 and the wall-side metal fitting 7 may slip against each other, causing the vertical accuracy of the guide rail 1 to be lost. Therefore, in order to prevent this, the horizontal piece 2d of the rail side metal fitting 2 and the horizontal piece 7d of the wall side metal fitting 7 are welded 16 after tightening the bolt 12, or a large-sized bolt or a high-tensile bolt is used. It is often used and tightened with great force.

The conventional elevator guide rail mounting device is configured as described above, and it is possible to increase the size of the bolt 12 by increasing the size of the bolt 12, or by using a high-tensile bolt for the bolt 12. It is difficult to tighten the bolts 12, and there is also the problem that the rail side and wall side metal fittings 2 and 7 that constitute the rail bracket need to be large in size. On the other hand, welding the horizontal piece 2d of the rail-side metal fitting 2 and the horizontal piece 7d of the wall-side metal fitting 7 after positioning them takes a long time and is expensive, and also causes the welding distortion of the bracket to cause the vertical alignment of the guide rail 1. This causes a decrease in accuracy, and there is a further problem that there is a risk of fire when removing elevators from existing buildings or constructing new ones. The invention of Party B was made to solve the above-mentioned problems, and it involves welding the rail side metal fittings and the wall side metal fittings, and prevents the guide rail from being distorted due to welding distortion of the bracket made up of these metal fittings. It is possible to prevent a decrease in vertical accuracy and the occurrence of a fire in an existing building, and the installation is highly efficient and inexpensive as there is no need to increase the size of the bolts that tighten the above two metal fittings or use high-tensile bolts. The object of the present invention is to provide a mounting device for an elevator guide rail.

The guide rail mounting device according to the present invention has a protrusion provided on at least one of the horizontal pieces of the wall-side metal fitting and the horizontal piece of the rail-side metal fitting, so that the horizontal piece of the two metal fittings can be secured between the horizontal pieces of the wall-side metal fitting and the rail-side metal fitting. It is possible to secure a gap thick enough to prevent the microcapsules of the intervening microcapsule-type adhesive that hardens at room temperature from being crushed, and the positioning operation of the two metal fittings can be performed without causing a curing reaction to the adhesive. The above-mentioned protrusion is deformed by the tightening force in the bolt axial direction by the subsequent bolt and nut, the microcapsules are crushed by the horizontal pieces of both metal fittings, and the hardening agent filled and sealed in them causes a chemical reaction in the adhesive. Let the adhesive harden and bond the horizontal pieces of both metal fittings together at room temperature. Therefore, it is possible to connect the horizontal pieces of both metal fittings with a large bonding force by using bolts, nuts, and a microcapsule adhesive that hardens at room temperature, so even if a large horizontal load is applied to the guide rail during an earthquake, The vertical accuracy of the guide rail can be maintained without using bolts or high-tensile bolts or by welding the horizontal pieces of both metal fittings.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. In FIGS. 1 and 2, the same reference numerals as in FIGS. 4 and 5 indicate the same or corresponding parts, and 17 is between the horizontal piece 7d of the wall side metal fitting 7 and the horizontal piece 2d of the rail side metal fitting 2. This adhesive is a microcapsule type adhesive that hardens at room temperature.As shown in Fig.
7a, and a curing agent hermetically filled in diameter-sized microcapsules 17b. Further, 7f is a protruding portion formed on the horizontal piece 7d of the wall-side metal fitting 7 so as to protrude from the upper surface of the peripheral edge portion of the elongated portion 7b. Then, in a state where the horizontal piece 7d of the wall-side metal fitting 7 and the horizontal piece 2d of the rail-side metal fitting 2 are overlapped, the protruding portion 7f abuts the lower surface of the rail-side metal fitting 2, and the horizontal piece 7d and the horizontal piece 2d are opposed to each other. A gap T is formed on the surface. The gap T is the thickness of the adhesive 17 interposed between the horizontal pieces 7d and 2d, and when the gap T is smaller than the diameter of the adhesive 170 and the microcapsule 17b,
The microcapsules 10b are crushed and the curing agent becomes the main agent 17.
a, a chemical reaction occurs, the adhesive 17 hardens, and the horizontal pieces 7d and 2d are bonded together. Further, the protrusion 7f can be processed at the same time as punching out the long size 7b using a special tool, and is pressed against the lower surface of the horizontal piece 2d by the force in the magnetic direction caused by tightening the bolt 12 to the nut 13, and by the standard tightening torque of the bolt 12. It is deformed by the generated axial force, making it rigid enough to be crushed completely. The configuration of this embodiment other than the above is substantially the same as that shown in FIGS. 4 and 5, but the horizontal pieces 7d and 2d are not welded. Next, the installation operation of the guide rail 1 according to this embodiment will be explained. First, the anchor bolt 8 is fixed to the shaft wall 11, and the wall-side metal fitting 7 is fastened to the shaft wall 11 using the anchor bolt 8. After that, apply the adhesive 17 to the upper surface of the horizontal piece 7d of the wall-side metal fitting 7, and in the state shown in FIG.
The horizontal piece 2d of the rail-side metal fitting 2, which is fastened to the guide rail 1 with bolts 4, nuts 5, etc., is superimposed on the horizontal piece 7d of the wall-side metal fitting 7. Furthermore, insert the bolts 12 into the long holes 7b and 2b of the horizontal pieces 7d and 2d, and
The protrusion 7f protruding upward from the periphery of b is brought into contact with the lower surface of the horizontal piece 2d, and the bolt 12 is tightened to the extent that the gap T between the horizontal piece 7d and 2=8-6 does not become smaller than the diameter of the microcapsule 10b. 13 to temporarily fix the horizontal pieces 7d and 2d. In this state, the guide rail 1 is
Perform centering work. By the way, in general, the time it takes for a room-temperature curing adhesive to start curing by a chemical reaction after the main ingredient and curing agent are mixed, that is, the pot life, varies greatly depending on the temperature. For this reason, when bonding work is done throughout the year, the annual average temperature is 15℃~
The base resin and curing agent are formulated to provide the best pot life at around 20°C. Therefore, in summer bonding work, the time required for the adhesive to begin to harden is shorter than in winter work, so it is necessary to perform the work in a short time. However, since the centering work of the guide rail 1 is performed with the gap T between the horizontal pieces 7d and 2d being larger than the diameter of the microcapsules 17b filled with the hardening agent of the adhesive 17, the microcapsules 17b may be crushed. Since the main resin 17a and the curing agent are not mixed, there is no problem even if the centering operation takes a long time or is interrupted in the summer. In addition, horizontal pieces 7d and 2d
In this case, only the protruding portion 7f is in contact with the horizontal piece 2.
d can be easily moved in the horizontal direction, and an appropriate frictional holding force is generated, so the horizontal pieces 7d and 2d do not need to be temporarily fixed with a jig or the like, and will not move naturally due to internal stress. . After centering and positioning the guide rail 1 as described above, tighten the bolt 12 to the standard torque value (
Fully tighten the bolts (size M16, approximately 1100 kg-cm), and fasten the horizontal piece 7a of the wall-side metal fitting 7 and the horizontal piece 2d of the rail-side metal fitting 2. By this fastening, the horizontal piece 7d,
2d becomes smaller than the diameter of the microcapsules 17b as the protrusion 7f is pressed against the horizontal piece 2d by the axial force generated by final tightening of the bolt 12, and these capsules 17b are crushed and the curing agent is removed. is the main agent 17a
be mixed into the Therefore, the adhesive 17 causes a chemical reaction and hardens, thereby bonding the horizontal pieces 7d and 2d to each other. Therefore, the centering work of the guide rail 1 is not limited by time even if it is carried out in the summer, and there is no need to temporarily fix the horizontal pieces 7d and 2d with jigs or tools. The metal fitting 7 and the rail side metal fitting 2 can be fixed. In the above embodiment, the protruding portion 7f was made to protrude from the periphery of the elongated portion 7b provided on the horizontal piece 7d of the wall-side metal fitting 7. 2b
It may be provided at the peripheral edge, or may be provided at the center of both or one of the horizontal pieces 7d and 2d of the metal fittings 7 and 2 so as to abut against the other side.

As explained above, according to the present invention, at least one of the horizontal piece of the wall-side metal fitting and the horizontal piece of the rail-side metal fitting is formed with a protruding portion that protrudes from the opposing surface and comes into contact with the horizontal piece of the mating metal fitting. , overlap the horizontal pieces of both metal fittings, tighten these horizontal pieces with bolts, deform the protrusion, and crush the microcapsules of the microcapsule-shaped adhesive that hardens at room temperature interposed between the horizontal pieces. Then, by mixing the hardening agent filled in these capsules with the main ingredient of the above-mentioned adhesive and curing the adhesive, the horizontal pieces of both metal fittings can be bonded together with a bolt, nut, and adhesive with a large bonding force. This allows the guide rail to be connected to each other without using large bolts, high-tensile bolts, or welding the horizontal pieces of both metal fittings together, making it possible to maintain the vertical accuracy of the guide rail even when large horizontal loads are applied during an earthquake. Preventing the guide rail from going out of alignment has the effect of improving workability during centering, and allowing the guide rail to be installed without fear of fire or welding distortion occurring in an existing building.
