The landing sill 13 has a top and bottom surfaces sandwiched between the sill catcher 16 and the sill retainer plate 17, and a washer 19 is interposed on the lower surface of the head of the butterfly bolt 18 to penetrate the sill catcher 16. The butterfly bolt 18 is inserted into the hole 16b from above, and the lower end screw portion of the butterfly bolt 18 is screwed into the screw hole 17a of the sill retainer plate 17 to be fastened and fixed.
9 and 10, 20 is the floor of the elevator hall, 21 is a weld anchor embedded in the floor 20, 22 is a reinforcing bar connecting the lower surface of the hall sill 13 and the weld anchor 21, and 23 is a hall sill 13. And a mortar that fills the welding anchor 21 and the reinforcing bar 22. For example, when the floor finish surface dimension A is narrow and the structure as in the first embodiment is used, if the strong magnet hits the floor portion 20, a structure in which the strong magnet as in the second embodiment is placed on the upper side is required. It becomes.

  In the above-described configuration, first, the pair of left and right sill centering tools 12 are inwardly directed toward each other in the vicinity of the lower end portion of the vertical angle 11 for mounting the three-sided frame having an L-shaped cross section that is vertically provided on both sides of the landing entrance. The lower end of the sill centering tool 12 is set in accordance with a landing finish reference ink (not shown). The pair of left and right sill centering tools 12 is attached to the vicinity of the lower end portion of the vertical angle 11 for attaching the three-way frame. The strong magnet 14 of the magnet holding part 15 attached to the upper surface of the sill receiving metal 16 of the sill centering tool 12 is used. It can be easily attached by adsorbing by the magnetic force. In addition, when it is desired to move the attachment position of the strong magnet 14, a plurality of (six in the figure) through-holes 16a through which a plurality of screws pass can be selected as appropriate. Next, while supporting the both end portions of the landing sill 3 on the upper surface of the sill retainer plate 17, the lower surface opposite to the attachment side end of the sill pad 16 of the sill centering tool 12 and the upper surface of the sill retainer plate 17 The washer 19 is interposed on the lower surface of the head of the butterfly bolt 18 with the landing sill 3 interposed therebetween, and the butterfly bolt 18 is inserted into the through hole 16b of the sill catcher 16 from above. The screw portion is fastened by being screwed into the screw hole 17a of the sill retainer plate 17 and temporarily fixed. In addition, since the lower end screw portion of the butterfly bolt 18 is screwed into the screw hole 17a of the sill retainer plate 17 from above, not only can the temporary sill 13 be temporarily fixed without using a tool, The wing bolt 18 can be easily removed from above without being obstructed by the floor 20. After entering and exiting on the basis of the piano wire, the front and rear direction reference ink, the center reference ink, and the height direction building reference ink are adjusted by adjusting the front and rear, left and right, and height of the sill pad 16 using a level. The threshold can be centered easily in a short time. This eliminates the need to weld the foundation plate to the reinforcing bar, eliminates the need for a vise to secure the receiver and a liner that adjusts the height between the receiver and the bottom of the sill. Since it can be shaped and simplified, an efficient threshold alignment work can be performed. Further, as shown in FIG. 10, even when the floor finished surface dimension A is narrow and the strong magnet hits the floor portion 20, the strong magnet 14 is installed on the upper side of the sill pad 16 so that the strong magnet is obstructive. There is no such thing as. Moreover, since the butterfly bolt 18 can be easily inserted and removed from above, it is easy to remove.
