BRIEF DESCRIPTION OF THE DRAWINGS FIG. Embodiment 1 FIG. FIG. 1 is a perspective view showing an essential part of an elevator sill device according to one embodiment of the present invention, and FIG. 2 is a cross-sectional view of the device of FIG. 1, where the same or corresponding parts as those in FIGS. And description thereof is omitted.

In the figure, reference numeral 21 denotes a mounting bracket fixed to a vertical portion of the building frame 5 by an anchor bolt 22. The mounting bracket 21 includes a vertical base 21a fixed to the vertical portion of the building frame 5 and a vertical base 21a. A horizontal portion 21b extending horizontally from the lower end of the vertical base 21a;
And a vertical mounting portion 21c extending upward from the landing side end.

An anchor bolt 22 is provided on the vertical base 21a.
There is provided a vertically elongated hole 21d through which
The mounting bracket 21 is fixed by a vertically long hole 21d so as to be movable up and down and in the front-rear direction. A support bolt 21e for supporting the mounting bracket 21 on the horizontal portion of the building frame 5 is screwed to the horizontal portion 21b. In the vertical mounting portion 21c,
A horizontally long hole 21f in the left-right direction is provided.

Numeral 23 denotes a receiving beam supported on the horizontal portion 21b of the mounting bracket 21, and this receiving beam 23 is formed by bending a steel plate to form a groove in cross section in the same manner as in the conventional example. One rising wall 23a is fitted in the vertical groove 7c, and the other bent wall surface 23b is in contact with the lower surface of the sill 7. At the lower end of the rising wall 23a, a through hole 23c facing the through hole 7b is provided. Further, the receiving beam 23 is provided on a receiving beam vertical piece 23d raised at both ends in the longitudinal direction, a plurality of screw holes 23e provided on the bottom portion, and a bent wall surface 23b abutting on the vertical mounting portion 21c of the mounting bracket 21. Screw hole 23f and opening 2 for operating support bolt 21e

Reference numeral 24 denotes a bolt which passes through the horizontally long hole 21f of the mounting member 21 and is screwed into a screw hole 23f of the receiving beam 23. The bolt 24 allows the receiving beam 23 to move in the left-right direction. 21. 25
And 26 are jack bolts screwed into a screw hole 23e of the receiving beam 23 and a screw hole (not shown) at the center in the longitudinal direction of the receiving beam 23, respectively. Can be moved up and down.

Next, the mounting procedure will be described. First,
The mounting bracket 21 is temporarily fixed to the left and right front ends of the receiving beam 23 with the bolts 14. That is, the bolt 14 is inserted into the horizontally long hole 21 f of the mounting bracket 21 and screwed into the screw hole 23 f of the receiving beam 23. Next, the anchor bolt 22 is driven into the vertical portion of the building frame 5, and the mounting bracket 21 to which the receiving beam 23 is connected is temporarily fixed.

Thereafter, the vertical dimension of the reference line (not shown) and the receiving beam 23 are determined by the vertically long holes 21d of the mounting bracket 21, and the mounting bracket 21 is fixed. Next, the support bolt 21e of the mounting bracket 21 is operated to support and fix the horizontal portion 21b. Then, the vertical groove 7c of the sill 7 is fitted to the rising wall 23a of the receiving beam 23,
The end of the sill 7 is received and brought into contact with the beam vertical piece 23d.

Then, accurate centering and leveling of the sill 7 in the vertical and horizontal directions are performed by the jack bolts 25 and 26 and the horizontally long holes 21f. At this time, the jack bolt 25,
The operation 26 is performed through a through hole (not shown) of the threshold 7. When this operation is completed, tighten the bolt 24,
Centering and fixing of the receiving beam 23 and the sill 7 are completed. Thereafter, the three-way frame and the like are assembled as in the conventional case.

In such an elevator threshold device,
Since the anchor bolt 22 is driven into the vertical part of the building skeleton 5, the anchor bolt hole can be easily drilled without being affected by the unevenness of the horizontal part of the building skeleton 5,
In addition, the mounting bracket 21 can be mounted horizontally, so that the threshold 7 can be easily centered and leveled. In addition, since the mounting bracket 21 has a horizontally long hole 21f,
Even if the width dimension of the building frame 5 is inaccurate, the mounting of the receiving beam 23 can be performed without being affected by it.

Embodiment 2 FIG. In the first embodiment, the mounting bracket 21 is attached and fixed to the vertical portion of the building skeleton 5 at the entrance 3. However, if it is the vertical portion of the building skeleton 5, it may be mounted to the hall 1 side or the hoistway 2 side. The same effects as in the first embodiment can be obtained.

[0022]

As described above, the elevator sill according to the present invention is characterized in that the vertical base of the mounting bracket is fixed to the vertical portion of the building frame using the anchor bolts so as to be movable in the vertical and longitudinal directions. Using a jack bolt, a receiving beam is mounted on the horizontal part so that it can be moved up and down, and a horizontal hole is provided in the vertical mounting part of the mounting bracket in the left and right direction, and the receiving beam is moved in the left and right direction by bolts that penetrate this horizontal hole. Since it is movably mounted, the anchor bolt hole can be easily drilled without being affected by the unevenness of the horizontal part of the building frame, and the mounting bracket can be mounted horizontally, thus centering the sill. In addition, effects such as easy leveling can be achieved. Also, because the mounting bracket has a horizontally long hole, even if the width of the frontage of the building frame is incorrect,
There is also an effect that the receiving beam can be attached without being affected by the influence.
