Connecting means which are provided so as to be buried in mutually opposing longitudinal ends of the guide portion and which inseparably connect the opposing end faces of the guide portion of the guide rail in the longitudinal direction of the guide rail. It is.

Thus, at the bent portion where the guide rail protrudes toward the car side due to the shaking of the building in which the elevator is installed due to an earthquake or the like, the guide rails are firmly connected to each other by both the eye panel and the connecting means. hand,
A load accompanying the occurrence of bending is supported by both of the above. For this reason, there is an effect of eliminating a problem in which the gap between the end faces of the guide rails facing each other is not generated and the movement of the guide provided on the car is prevented. In addition, since it is not necessary to use a so-called reinforcing plate to increase the thickness of the connecting plate, and because the reinforcing plate is provided, the required space for the connecting portion of the guide rail increases, and the cross-sectional area of the hoistway increases. This has the effect of eliminating the problem that the space efficiency of the building decreases. Further, since it is not necessary to handle a heavy reinforcing plate, the operation efficiency of installing the guide rail is improved, and the installation cost of the elevator is reduced.

As described above, according to the present invention, a base having a T-shaped horizontal shape and a guide portion having a T-shaped draft are formed so that the longitudinal end faces thereof are opposed to each other. Each of the guide rails erected in series with the hoistway, and the end portions of the guide rails that are formed in a "U" shape in a free posture and whose receding refraction surfaces are overlapped with the longitudinal ends of the guide rails and oppose each other Elastic guide plates, which are elastically deformed and fastened, and apply opposing pressing forces to the longitudinal end surfaces of the guide rails facing each other by the elastic deformation.

Accordingly, at the bent portion in the direction in which the guide rail projects toward the car side due to the shaking of the building in which the elevator is installed due to an earthquake or the like, the end faces of the guide rail opposed to each other by the elastic blind plate are pressed against each other. The pressure acts, the guide rails are firmly connected to each other, and the load accompanying the occurrence of bending is supported. Therefore, no gap is generated between the mutually facing end faces of the guide rail,
This has the effect of eliminating the problem that the movement of the guide provided on the car is hindered.

Claims (3)

[Claims] 1. A base having a T-shaped horizontal section and a guide section including a T-shaped vertical section are formed, and the longitudinal end faces thereof are opposed to each other, and are erected in series in a hoistway. A guide rail, a facing plate on the back of the base at the longitudinal ends of the guide rails, which is fastened to each of the bases facing each other, and a mutual connection between the opposed longitudinal ends of the guides. A guide rail device for an elevator, comprising: connecting means provided in a buried state and mutually inseparable end faces of the guide portion are inseparably connected in a longitudinal direction of the guide rail. 2. A T-shaped cross section, a base formed of a T-shaped horizontal picture and a guide section formed of a T-shaped draft are formed, and are set up in a hoistway in series with their longitudinal end faces facing each other. The guide rail and the refracted refracting surface in the shape of a "K" in a free posture are overlapped with each other at the longitudinal ends of the guide rail, and are elastically deformed and fastened to each of the longitudinal ends opposed to each other. A guide rail device for an elevator, comprising: a plurality of elastic end plates for applying opposing pressing forces to the longitudinal end surfaces opposing each other by elastic deformation. 3. The face plate is formed in a "U" shape in a free position, and the "U" retreating refracting surfaces are overlapped with each other at the longitudinal ends of the guide rail, and each of the longitudinal ends opposed to each other has elasticity. 2. A guide rail device for an elevator according to claim 1, wherein said longitudinal end surfaces which are deformed and fastened and which are opposed to each other by elastic deformation are elastic plates which apply opposing pressing forces to each other.
