Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an installation centering device for a landing entrance sill in an elevator.

The conventional installation centering procedure for landing entrance/exit sills is to first hang a reference piano wire into the hoistway where the elevator will be installed, and then align this with the building floor finish marked on the wall of the hoistway entrance/exit by the construction contractor. Do this based on the reference line.

That is, in FIGS. 1 and 2, the landing entrance sill 1 is temporarily fixed to a fixed bracket 2 with bolts 17 and nuts 18, and the fixed bracket 2 is fixed with anchor bolts 15 and nuts that have been driven into the building wall 14 in advance. 16, the upper surface 1b of the landing entrance/exit sill 1 is temporarily fixed so that it approximately coincides with the building floor finishing reference line 10 marked on the loading/unloading path entrance/exit wall 14a.

In addition, a reference piano wire 11, which serves as a reference for installation centering of the landing entrance sill 1, etc., is suspended and fixed from the top of the hoistway in advance.

For the centering work, first, apply the scale 12 to the end surface 1c of the landing entrance sill 1 so as to be perpendicular to the reference piano wire 11,
The hall entrance sill 1 is moved on the fixed bracket 2, and the distance between the end face 1c of the hall entrance sill 1 and the reference piano wire 11 is adjusted to a specified dimension.

Next, the scale 12 is applied to the top surface 1b of the landing entrance sill 1, and the top surface 1b of the landing entrance sill 1 is aligned with the building floor finishing reference line.
Adjust the fixing bracket 2 by moving it up and down so that it matches 0, and also place a spirit level 1 on the top surface 1b of the landing entrance sill 1.
3, and insert a liner 19 made of a thin steel plate between the hall entrance sill 1 and the fixed bracket 2 so that the hall entrance sill 1 is horizontal.

After repeating the above operation several times alternately and determining the position of the landing entrance/exit threshold 1, tighten the anchor bolts 15 and nuts 16 to fix the fixing bracket 2 to the building wall A4, and tighten the nuts 18 of the bolts 17. Fix the landing entrance/exit sill 1 to the fixing bracket 2, and fix the landing entrance/exit sill 1.
The installation centering work is completed.

In the conventional installation method described above, work is done in a dimly lit elevator hoistway, and work efficiency is poor as it is necessary to read fine markings on a scale.Also, due to individual differences among workers and misunderstandings of dimensions, rework is required. occurs,
This caused backtracking work and increased installation man-hours.

An object of the present invention is to provide an installation core for an elevator landing entrance sill that overcomes the above-mentioned drawbacks of the prior art, can make installation accuracy uniform regardless of individual differences and abilities of workers, and can improve work efficiency. It is to provide the extraction device.

Hereinafter, the present invention will be explained in detail using the embodiment shown in FIGS. 3 and 4.

Driving the anchor bolt 15 into the building wall 14, temporarily fixing the fixing bracket 2 to the building wall 14, temporarily fixing the landing entrance sill 1 to the fixing bracket 2, and hanging and fixing the reference piano wire 11 are the same as in the conventional construction method. Let's do it.

Next, the installation member 20 is attached to the door guide groove 1a of the landing entrance sill 1.

A marking line 20a is engraved on the installation 20 at a position such that the distance between the end surface 1c of the landing entrance sill 1 and the reference piano wire 11 is a specified value, and a level 20c is embedded or removable. In addition to being attached to the shaft, it has a sufficient length to reach the building floor finishing reference line 10 marked on the shaft entrance/exit wall 14a.

Therefore, the marking line 20a of the installation wire 20 is the standard piano wire 1.
Adjust the landing entrance/exit threshold 1 by moving it back and forth so that the lower surface 20d of the installation 20 matches the building floor finish reference line 1.
Adjust the fixing bracket 2 by moving it up and down so that it matches 0, and while watching the level 20c prepared for the installation 20, align the landing entrance sill 1 and the fixed bracket so that the landing entrance sill 1 is level. A thin steel plate liner 19 is inserted between 2 and 2.

After completing the centering of the landing entrance sill 1 as described above,
The fixed bracket 2 is fixed to the building wall surface 14 by tightening the anchor bolt 15 and nut 16, and the landing entrance sill 1 is fixed to the fixed bracket 2 by the bolt 17 and nut 18.

According to the above embodiment, errors due to differences in the ability of individual installation workers are eliminated, installation can be performed with uniform accuracy, there is no backtracking work due to misreading of the scale, and the number of installation man-hours can be reduced. It has the effect of being answered.

FIG. 5 shows another embodiment, which differs from the embodiments shown in FIGS. 3 and 4 in that a communicating tube is used instead of a level.

That is, in the embodiment described above, the communication pipe 21 is installed in the notch groove 20b provided in the fixture 20 instead of the spirit level 20c,
This communication pipe 21 is used to adjust the horizontal centering of the landing entrance sill 1.

According to the embodiments described above, it is possible to adjust the horizontal centering with high precision without using a spirit level that is easily damaged.

As explained above, the present invention has the remarkable effect of eliminating scale misreading in a dark hoistway and variations in accuracy due to differences in worker ability, and allowing installation with uniform accuracy using a simple method. There is.
