Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator guide rail in a unit type building, and in particular, a guide portion of an elevator car is slidably fitted on the guide rail, whereby the elevator car is guided to move up and down. It can be used for elevators.

[0002]

BACKGROUND ART As a method of constructing a unit-type building having an elevator installed therein, there is a method disclosed in Japanese Patent Application No. 6-212559 filed by the applicant of the present application. According to this construction method, an elevator shaft constituent part is formed inside a plurality of building units produced in a factory, and vertically extending guide rails are provided in the elevator shaft constituent part for each building unit. By vertically combining the plurality of building units at the site, a vertically continuous elevator shaft and a continuous long guide rail are formed inside the building. In addition, it is common practice to avoid gaps between the opposite ends of the upper and lower guide rails.By installing each guide rail at a predetermined position in the building unit at the factory, the upper and lower buildings can be installed at the construction site. By combining the units, the guide rails will be continuous without any gaps.

[0003]

However, when building units are combined vertically, even if each guide rail is attached at a predetermined position of the building unit, the accuracy of the combination and the accuracy of assembling each building unit itself are high. As a result, the opposite end portions of the upper and lower guide rails may be displaced in a direction toward each other. Then, in such a case, the opposite ends of the guide rails collide with each other, causing a slight horizontal distortion in each guide rail. For this reason, there is a problem that the elevator car cannot be smoothly moved up and down due to this minute distortion, and the riding comfort of the elevator is impaired.

The object of the present invention is to reduce the riding comfort of the elevator even if the opposite ends of the upper and lower guide rails are displaced toward each other due to the accuracy of assembly of the upper and lower building units and the accuracy of assembly of each building unit itself. It is to provide a guide rail in a unit building that does not exist.

[0005]

A guide rail for an elevator in a unit-type building according to the present invention is pre-installed at the upper and lower elevator building units constituting a unit-type building with an elevator in a factory, and an elevator car for elevators is also installed. Is a guide rail of an elevator in a unit type building in which a guide portion provided in a vertically slidable fit is installed, and the opposite end portions of the elevator guide rails are attached to each of the elevator building units that are vertically combined. It is characterized by being.

[0006] Here, the term "attached separately" means
Due to the combination accuracy of the upper and lower building units and the assembly accuracy of each building unit itself, when the upper and lower guide rails are not arranged accidentally apart, but when the upper and lower building units are combined, each guide rail intentionally It is a state of being separated.

In the above, the guide rail according to the present invention is formed in a plate shape that is long in the vertical direction, and has a sliding portion on which the guide portion of the elevator car slides, and the opposite end portions of this sliding portion. Is preferably tapered, and the opposite ends thereof are preferably tapered over the entire circumference.

The guide portion of the elevator car is formed with a substantially C-shaped cross section, and the guide rail is provided with a guide rail fitting portion to which the guide rail is fitted. It is desirable that the ends are flared, and that the upper and lower ends of the guide rail fitting portion are flared over the entire area.

[0009]

In the present invention as described above, the guide rails of the elevator building units combined vertically are installed with their opposing ends separated from each other, so that the accuracy of the combination of the upper and lower building units and the assembly of each building unit itself are improved. Due to the accuracy, even if the opposing ends of the upper and lower guide rails are displaced so that they are close to each other, this amount of displacement is absorbed by the gap between the opposing ends of each guide rail, so that the opposing ends do not collide with each other. . Therefore, the horizontal distortion of each guide rail is prevented, and the ride comfort of the elevator is improved.

In the above, each guide rail is provided with a sliding portion which is formed in a vertically long plate shape and on which the guide portion of the elevator car slides, and the opposite ends of the sliding portions are tapered. By forming the tapered portion by, for example, a taper or the like, even if the upper and lower guide rails are displaced from each other in the horizontal direction, the amount of this displacement can be absorbed by the taper.

Further, when the opposite ends are tapered over the entire circumference, even if the upper and lower guide rails are displaced in any horizontal positional relationship, the displacement amount can be absorbed.

The guide portion of the elevator car is formed to have a C-shaped cross section, and a guide rail fitting portion for fitting the guide rail is provided on the guide portion. In the case where the guide is widened toward the end, the amount of horizontal shift between the upper and lower guide rails can also be absorbed by this guide portion.

Further, when the upper and lower end portions of the guide rail fitting portion are spread over the entire area, it is possible to more reliably absorb the horizontal shift amount between the upper and lower guide rails.
