Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of mounting a guide rail of an elevator in a unit type building and the guide rail, and is particularly applicable to a guide rail mounted at a construction site.

[0002]

BACKGROUND ART Conventionally, a guide rail for guiding the raising and lowering of an elevator car is installed in an elevator space in which an elevator car for elevators moves up and down, and a building unit produced at a factory is assembled at a construction site to be built. In a unit type building, an elevator space is formed inside by combining a plurality of building units vertically. In such a unit-type building, in order to install vertically continuous guide rails in the elevating space, for example, a rail member is previously installed at a predetermined position of each building unit forming the elevating space at the factory, and those building units are installed. A method is conceivable in which the units are combined vertically at the construction site to form an elevating space and at the same time make each rail member continuous vertically to form one long guide rail.

As another method, first, a plurality of building units are vertically combined at a construction site to complete an ascending / descending space, and then a continuous long guide rail is suspended in the ascending / descending space from above by a crane. Depending on the situation, a method of attaching may be considered.

[0004]

However, in the former method, when building units are vertically combined at a construction site, each building unit is installed even though each rail member is attached at a predetermined position of the building unit. Due to the combination accuracy of, a slight deviation occurs between the upper and lower rail members. For this reason, it is difficult to surely form the guide rail composed of these rail members in a linear shape only by vertically assembling the building units.

On the other hand, in the latter method, since the guide rails are long and continuous, the guide rails cannot be easily handled at the construction site, and there is a problem in workability.

An object of the present invention is to provide a method for mounting an elevator guide rail in a unit type building, which can surely form a straight line even if it is composed of a plurality of members and can improve workability at a construction site. And to provide its guide rails.

[0007]

A method of mounting an elevator guide rail in a unit type building according to the present invention comprises a plurality of building units produced in a factory and having vertical spaces extending vertically at corresponding positions. By combining the above and below at the construction site, a vertical space is created in which the vertical spaces of these elevators are continuously moved up and down, and in the unit type building that is installed inside this vertical space and guides the vertical movement of the elevator car. A method of mounting a guide rail of an elevator, wherein a plurality of rail members are prepared, an engaging portion that engages with these rail members is provided in an elevator car, and a drive device for raising and lowering the elevator car is provided. It is installed inside the elevator car and at least one rail member of the multiple rail members is installed in the elevator space. After that, an elevator car is movably engaged with the at least one rail member via an engaging portion, and then a rail member different from the rail member is temporarily fixed to the upper portion of the at least one rail member. Then, the elevator car is lifted by manipulating the driving device by a person in the elevator car, and further, the engagement is maintained while the engagement portion and the at least one rail member are maintained while the elevator car is being raised. It is characterized in that the upper end of the joint portion is engaged with the temporarily fixed rail member, and then the temporarily fixed rail member is finally fixed in the ascending / descending space.

In the present invention as described above, at the beginning, the engaging portion of the elevator car is engaged only with the rail member initially attached to the elevator space, but the elevator car is driven by a human inside. By ascending by operating the device, the engaging portion also engages with the temporarily fixed rail member on the upper portion. In other words, at this point, the engaging part of the elevator car will be engaged across the upper and lower rail members, and therefore the position of the temporarily fixed rail member will be corrected automatically following the engaging part. At the same time, the position of the rail member initially attached to the ascending / descending space is matched. At this time, by temporarily fixing the temporarily fixed rail member, the upper and lower two rail members are surely linear without being displaced from each other. Therefore, when the temporarily fixed rail member is finally fixed, another rail member is temporarily fixed to the upper portion of the finally fixed rail member, and if this work is repeated an arbitrary number of times based on the above-described mounting method. Therefore, it is possible to reliably form a guide rail having a linear shape and having an arbitrary length. Further, since the guide rail is composed of a plurality of rail members, it is not necessary to handle a long continuous guide rail as in the conventional construction site, and workability at the construction site is improved.

The above-mentioned drive device may be of a manual type or an electric type, and the drive operation may be performed by a person in the elevator car.

Furthermore, it is desirable to drive the drive device to raise and lower the elevator car along the rail member by providing the drive device with a pinion and the rail member with a rack that meshes with the pinion. Has
Since the rack and the rail member can be used in common, the labor of preparing the rack as a separate member can be saved.

On the other hand, the guide rail of the elevator in the unit type building of the present invention is attached by the above-mentioned guide rail attachment method, and is separately attached to the rail member attached to the ascending / descending space and the upper portion of this rail member. Of the rail car, and the elevator car is provided with an engaging portion that engages with each rail member, and a drive device for raising and lowering the elevator car is installed inside the elevator car. The elevator car is engaged with each rail member so as to be able to move up and down by manual operation of a drive device by a person inside the elevator car.

In the present invention as described above, the guide rail is attached to the ascending / descending space by the method described above,
The guide rail itself will be straight, and the workability at the construction site will be improved.

As shown in FIGS. 2 and 3, the rail member 18 is provided at a flat rail main body 20 with which the engaging member 13 of the elevator car engages, and at both ends in the longitudinal direction of the rail main body 20. The rail main body 20 is provided with a rack 22 that meshes with the pinion 17 along the longitudinal direction of the rail main body 17. Further, a bolt hole 21A is formed in the mounting portion 21, and the rail member 18 is screwed to the support member of the building unit by inserting a bolt into the bolt hole 21A. Here, 17A in FIG. 3 is a rotation shaft of the pinion 17.

In FIG. 1, the engaging member 13 on the side where the driving device 14 is not provided does not need an opening, and the rail member 1 of the guide rail 10 that engages with these is not necessary.
No rack is installed in 8. Further, in the guide rail 10, the rail main body 20 of the rail member 18A attached to the lowermost position is formed so as to extend below the rail main bodies of the other rail members 18.

Next, a method of mounting the guide rail 10 will be described with reference to FIGS. 4 and 5. In FIG. 4, first, the number of rail members 18 required to form the guide rails is put in a carriage or the like and prepared. Next, the elevator car 8 is carried into the upper and lower space 7 of the first-floor building unit 3A.
At this time, the raising / lowering car 8 is provided with the engaging member 13, the driving device 14 is installed inside the raising / lowering car 8, and the carriage containing the rail member 18 is also positioned inside the raising / lowering car 8.

Then, the rail member 18A attached to the lowermost position of the plurality of rail members 18 is installed in the lifting space 9

In FIG. 5, the upper end 13B of the engaging member 13 is engaged with the temporarily fixed rail member 18B while maintaining the engagement between the engaging member 13 and the rail member 18A while the elevator car 8 is being raised. At this point, the rail member 18
B is permanently fixed to the support member 19.

Next, based on the above-described mounting method, another rail member 18C is taken out, and this rail member 18C is positioned above the rail member 18B and temporarily fixed to the support member 19. Then, the elevator car 8 is driven by the drive device 14
The rail member 18C in which the upper end 13B of the engaging member 13 is temporarily fixed while the handle 16 of the engaging member 13 is raised by rotating, and the engagement between the engaging member 13 and the rail member 18B is maintained while the elevator car 8 is being raised. The rail member 18C is finally fixed to the support member 19 at this point. After that, the above-described mounting method is further repeated to mount the remaining rail members 18, thereby forming the vertically continuous guide rail 10 in the elevating space 9.

According to the present embodiment, the following effects can be obtained. That is, the rail member 18B temporarily fixed to the upper portion of the rail member 18A comes to be engaged with the upper end 13B of the engaging member 13 in the elevator car 8 as the elevator car 8 is raised. 13 is engaged across the rail member 18A and the rail member 18B. Therefore, since the rail member 18A is previously attached to the support member 19 and positioned, when the engaging member 13 engaged with the rail member 18B is also engaged with the provisionally fixed rail member 18B, the provisional fixing is performed. The position of the rail member 18B is automatically corrected and coincides with the position of the rail member 18A. Therefore, at this point, the rail member 18B is finally stopped, so that the upper and lower two rail members 18A and 18B can be made linear with each other. Therefore, even if the rail member 18C temporarily fixed to the upper portion of the rail member 18B and other rail members 18 are similarly positioned, even if the guide rail 10 is formed from a plurality of rail members 18, it is surely linear. can do.

Further, since the guide rail 10 is divided into a plurality of rail members 18, the guide rail 10 can be handled more easily than the conventional long continuous one, and the workability at the construction site is improved. Can be improved.

The work of mounting the guide rail 10 can be performed by one worker in the elevator car 8, and the labor of the worker can be saved.
