Abstract
Provided is a guide rail device for an elevator, which includes a plurality of fixing bodies. Among the plurality of fixing bodies, a fixing body that is the closest to a fishplate is referred to as a first fixing body, and a fixing body that is the second closest to the fishplate is referred to as a second fixing body. Further, a distance between a position of the first fixing body and a position of the second fixing body in a vertical direction is referred to as a rail fixing distance. In this case, a distance from the position of the first fixing body to a position of the fishplate in the vertical direction is one-third or less of the rail fixing distance.
Claims2
A guide rail device for an elevator, comprising:
- a guide rail main body that is installed in a hoistway, includes a plurality of rail members joined together in an up-and-down direction, and is configured to guide vertical movement of a vertically movable body;
- a fishplate configured to couple two of the plurality of rail members, the two rail members being adjacent to each other in the up-and-down direction;
- and
- a plurality of fixing bodies configured to fix the guide rail main body to a building,
- wherein the hoistway has a flexible structure, and
- wherein, when a fixing body that is the closest to the fishplate among the plurality of fixing bodies is referred to as a first fixing body, a fixing body that is the second closest to the fishplate is referred to as a second fixing body, and a distance between a position of the first fixing body and a position of the second fixing body in a vertical direction is referred to as a rail fixing distance, a distance from the position of the first fixing body to a position of the fishplate in the vertical direction is one-third or less of the rail fixing distance.
