<P>PROBLEM TO BE SOLVED: To provide the guide rail connection structure of an elevator capable of installing a second joint plate between a guide rail and an elevation path wall even when a gap between the guide rail and the elevation path wall is relatively narrow. <P>SOLUTION: The guide rail connection structure of an elevator includes: an additional joint plate 3 having a female screw part 7 and a guide rail movement prevention hole 6 into which a nut 5 screwed to a first bolt 4 for fixing an already installed joint plate 2 so as to abut on the already installed joint plate 2 for connecting first guide rail 1a and a second guide rail 1b; and a second bolt 8 inserted from the guide rail 1 side into the bolts holes 11a and 11b of the first guide rail material 1a and the second guide rail material 1b and the bolt hole 2a of the already installed joint plate 2 to be screwed to the female screw part 7 of the additional joint plate 3. Thus, even when the gap between the guide rail 1 and the elevation path wall 9 is relatively narrow, the additional joint plate 3 can be also installed between the guide rail 1 and the elevation path wall 9. <P>COPYRIGHT: (C)2012,JPO&INPIT |
