Place the sill plate (8) on the horizontal surface of 6) and attach it with bolts (9).

Then, mortar (10) is poured into the gaps between the lower edge (1a) of the entrance/exit of the hoistway (1), the entrance/exit post (2), and the weir plate (11) to finish the floor area of the landing.

In order to support the load of passengers and luggage trolleys, the threshold of the elevator hall is provided with the required number of mounting brackets (4), etc., as described above, and mortar (10) is poured in to obtain the necessary strength.

Note that foreign matter such as dust that has fallen into the guide groove (8a) of the sill plate (8) is discharged from the through hole (8b), thereby preventing the foreign matter from interfering with the opening and closing of the door (3).

[Problems to be Solved by the Invention] However, since the threshold of a conventional elevator hall is configured as described above, when the width of the entrance to the hall is wide and the total length of the threshold becomes long, the strength of the threshold becomes insufficient. Therefore, it was necessary to provide a large number of mounting brackets (4) and the like. Therefore, a large number of man-hours were required to fix the threshold. Also,
If someone were to accidentally stand on the tip of the sill during installation or maintenance work, this part could become deformed.

Therefore, it is an object of the present invention to provide a threshold for an elevator hall that can obtain the required strength through simple work.

[Means for Solving the Problems] The sill of an elevator landing according to the present invention includes a reinforcing beam having a groove-shaped cross section opening downward on the lower surface of the sill plate disposed at the lower edge of the entrance of the landing. It was established.

[Function] According to the present invention, a reinforcing beam having a groove-shaped cross section opening downward is provided on the lower surface of the sill plate, so that the sill can obtain the required rigidity. Further, the refracting surface of the reinforcing beam on the landing side prevents mortar from flowing into the hoistway when mortar is poured into the gap between the lower edge of the hoistway entrance and the doorway pillar.

Furthermore, a toe guard can be attached to the refracting surface of the reinforcing beam on the hoistway side.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 to 3.

FIG. 1 is a front view showing a threshold of an elevator hall according to an embodiment of the present invention, FIG. 2 is a side view of FIG. 1, and FIG. 3 is a main part of a threshold of an elevator hall according to an embodiment of the present invention. FIG. In the drawings, the same reference numerals as in FIGS. 4 and 5 indicate parts that are the same as or correspond to conventional components, so their explanation will be omitted here.

In the figure, (13) is a bolt (
This reinforcing beam is attached by the sill plate (8) and has a groove-shaped cross section with a downward opening, and is made of a steel plate with approximately the same length as the sill plate (8). The bottom surface (1) of the reinforcing beam (13)
3a) has a garbage trap hole (13b) in a position facing the through hole (8b) of the sill plate (8), and the tip of the refractive surface (13c) on the landing side It is in contact with the corner of the lower edge (1a) of the entrance/exit of the passageway (1). This refractive surface (1 3 c) is provided at a portion necessary to prevent the mortar (10) from flowing out toward the hoistway (1) during construction. Furthermore, the refracting surfaces (13d) on the hoistway side of the reinforcing beam (13) are provided at both left and right ends necessary for attaching the toe guard (12). Also,
The lower side of the bottom surface (13a) of this reinforcing beam (13) is placed on the sill supporter (6), and together with the sill plate (8), the bolt (9)
) is attached to the sill support (6). A toe guard (12) is attached to the refraction surface (13d) of the reinforcing beam (13) on the hoistway side by screwing its upper end.

The installation of the threshold of the elevator hall of this embodiment constructed as described above is carried out as follows.

First, as in the conventional example, a plurality of fittings (4) are placed on the lower inner wall of the entrance/exit of the hoistway (1) at a predetermined interval laterally, and the grooves are aligned toward the inside of the hoistway (1). Open it and fix the bottom of the groove with an anchor bolt (5). Then, the horizontal surfaces of each sill holder (6) are aligned in height, and the downwardly bent surface is attached to the side wall of the mount (4) with bolts (7).

Next, the reinforcing beam (13) and the sill plate (8) are placed on the horizontal surface of the sill support (6) and attached with bolts (9). Further, the mortar (10) is applied to the lower edge (l) of the entrance/exit of the hoistway (1).
a) Finish the floor area of the landing by pouring it into the gap between the entrance pillar (2) and the reinforcing beam (13) and the refractive surface (1 3 c) on the landing side. Then, the tip of the toe guard (12) is screwed to the refraction surface (1 3 d) on the hoistway side of the reinforcing beam (13).

By the way, by providing the reinforcing beam (13), the rigidity of the sill is improved, so the installation location of the mounting bracket (4) and the sill support (6) in the above configuration is 2 at both ends of the width of the entrance/exit of the hall. It is also possible to specify only the location.

Note that foreign matter such as dust that has fallen into the guide groove (8a) of the sill plate (8) is discharged from the through hole (8b) and the through hole (13b).

As described above, the threshold of the elevator hall of this embodiment is provided with a reinforcing beam (13) whose cross section is opened downward on the lower surface of the threshold plate (8).

Therefore, according to this embodiment, since the sill can obtain the required rigidity, the mounting bracket (4) and the sill support (6)
