Description

[Detailed description of the invention] This invention relates to an elevator system.

First, a conventional elevator system will be explained with reference to FIGS. 1 and 2.

In the figure, 1 is the elevator hoistway, 2 is the surrounding wall of the hoistway 1, 3 is the opening provided on each floor 4 of the hoistway 1, and 5 is the three sides that cover the opening 3 and constitute the entrance/exit 6 of the landing. It is appropriately fixed to the surrounding wall 2 with a frame.

Reference numeral 7 denotes a hanging wheel case placed above the entrance/exit 6, whose lower end is supported by the three-sided frame 5, and whose upper end is an L-shaped fixture 8.
It is appropriately fixed to the surrounding wall 2.

Reference numeral 9 indicates a rail disposed inside the hanging wheel case 1; 10 indicates a hanging wheel that suspends the upper end of the door 11 for opening and closing the doorway 6 and rolls on the rail 9; 12 indicates a rail disposed below the doorway 6; The threshold is provided with a guide groove 12a for guiding a guide piece 13 provided at the lower end, and is appropriately fixed to the surrounding wall 2 with an L-shaped fixture 14.

15 is a finishing material made of mortar or the like that finishes the surface 15a of each floor 4 flush with the upper surface of the threshold 12.

The elevator system configured in this manner is installed in the following order.

First, determine the position of the threshold 12 from the core of the building, and
Fix it to the surrounding wall 2 with.

Next, the three-sided frame 5 is appropriately fixed to the surrounding wall 2.

Furthermore, the lower end of the suspension wheel case 7 containing the rail 9 and the suspension wheel 10 is fixed to the three-sided frame 5, and the upper end is fixed to the surrounding wall with a fixture 8.

Next, the door 11 is hung with the hanging wheel 10.

When the above work is completed by the elevator worker, the construction worker closes the lower surface of the gap A between the surrounding wall 2 and the sill 12 with a partition board (not shown), etc.
A finishing material 15 is poured on top of the sill 12 up to the upper surface of the sill 12.
5a is completed.

Elevator equipment that is completed in this order has the following disadvantages when there is a recent tendency to shorten the construction period.

In other words, the work order is fixed, and it is necessary to complete the finishing work on floor 4 after the installation of the elevator equipment is completed, and if the installation work of the elevator equipment is delayed, all subsequent work will be delayed, which is the worst case scenario. In this case, the completion of the building will be delayed.

Furthermore, the work of closing the lower surface of the opening A is difficult and consumes a lot of time and money.

In addition, in order to pour the finishing material 15 to the position of the sill 12,
Some of it sometimes adheres to the surface of the sill, which requires a lot of time to clean.

The present invention solves the above-mentioned drawbacks and provides an elevator system in which the order of work in a building is not fixed.

An embodiment of the present invention will be described below with reference to FIGS. 3 and 4.

In the figure, the same reference numerals as in Figures 1 and 2 indicate all the same parts, and 16
is a fixture having a cross-sectional shape, and its vertical side 16a is aligned with the surface 12b of the sill 12 facing the floor 4, and its horizontal side 16b is appropriately fixed to the lower surface of the sill 12 by welding or the like.

16c is a long hole provided perpendicularly to the vertical side 16a;
Reference numeral 7 denotes a cross-sectional cross-sectional span plate, with a screw hole 17b provided on a vertical side 17a at a position corresponding to the elongated hole 16c, and a horizontal side 17c fastened with a bolt 18 having a finished surface 1.
Touches 5a.

That is, after finishing the floor 4, the horizontal side 1 is formed on the surface 15a.
The span plate 17 is fixed by bolts 18 at the positions where the parts 7c contact.

Therefore, in the elevator system of this structure, the finishing material 15 is
The finishing work on the floor 4 can proceed independently even without the sill 12 because it is sufficient to pour it to a position slightly set back and away from the facing surface 12b of the floor 4.

Further, there is no need to close the lower surface of the opening A, resulting in labor savings.

Furthermore, by storing the spanboard 17 in a separate location during various operations and attaching it last, the finish will be beautiful because it will not get dirty or scratched.

Further, by configuring the span plate 17 to be adjustable in the vertical direction, the accuracy of the vertical position of the surface 15a or the vertical position of the sill 12 can be relaxed, and the working time can be shortened.

FIG. 5 shows another embodiment of the present invention.
, the same reference numerals as in FIG. 4 indicate the same parts, and 19 is the spanning board 17
It is a flexible member made of an elastic body such as rubber and is attached so as to cover the tip of the holder, and the other structure is the same as that of the embodiment shown in FIGS. 3 and 4.

Therefore, although a detailed explanation will be omitted, it is clear that similar effects can be obtained in this embodiment as well.

Moreover, even if there are some irregularities on the surface 15a of the floor 4 due to the flexible material 19, the elevator system can have a good appearance without any gaps over the entire length of the span plate 17 on the finished surface 15a.

As explained above, the present invention provides an elevator system that can be easily installed by providing a vertically adjustable spanning board between the threshold and the floor surface, thereby eliminating the restriction on the order of floor finishing between the elevator system and one building. This is to realize the following.
