Abstract

PURPOSE:To perform the centering of an indicator box so accurately in a simple manner by installing a means for holding this inciator box and plural pieces of jack bolts, respectively, and after the indicator box is temporarily installed, making length of the jack bolt variable, and positioning the indicator box aright. CONSTITUTION:This centering device is provided with means 4a, 4b holding an indicator box 1 and plural pieces of jack bolts 5a, 5b each projecting length is variable and, after they are temporarily attached to an indicator box installed position, each length of these jack bolts 5a, 5b is made variable, positioning this indicator box 1. Subsequently, this indicator box 1 is welded to a reinforcing bar in a building wall, and after completion of welding, these jack bolts 5a, 5b are removed. Thus, the indicator box is able to be simply locked to the building wall and the indicator box is accurately positioned in a quick manner. In addition, such a possibility that dislocation might be caused in the duration up to being welded after centering is preventable.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indie box centering device for an elevator.

[0002]

2. Description of the Related Art Generally, in the installation of an indigo box, which is carried out when an elevator is installed, it is necessary to dispose it at an appropriate position from a three-way frame and a floor.

Conventionally, the installation of the indie box is performed by inserting the indie box into a through hole provided in a building wall, and temporarily fixing it by inserting a piece of wood or the like into the gap, and correcting it to the appropriate position. It was welded to the reinforcing bars on the building wall and fixed.

[0004]

Conventionally, in the installation of the indie box, a wood piece or the like is stuffed in the gap between the through hole provided in the building wall and the indie box and temporarily fixed, and the reference dimension is measured by a scale and corrected. However, there are drawbacks in that it takes time and effort to find a piece of wood of an appropriate size, and there is a large possibility of misalignment between the temporary fixing and the welding and fixing.

An object of the present invention is to provide an elevator indie box centering device capable of centering an inbox easily and accurately.

[0006]

In order to achieve the above-mentioned object, the present invention provides a means for holding an indigo box in an indigo box centering device for an elevator used during an indigo box installation operation for installing an elevator, A plurality of jack bolts having variable projecting lengths are provided, and after being temporarily mounted at the mounting position of the indic box, the lengths of the jack bolts are varied to position the indivox.

[0007]

With the above-described structure, after the indigo box is held on the centering device, it is temporarily mounted together with the centering device on the building wall, and the length of each jack bolt can be varied to easily and accurately operate the indigo box. Centering can be performed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of a landing showing an embodiment of the present invention, FIG. 2 is an enlarged front view of an essential part of FIG. 1, and FIG. 3 is an enlarged side sectional view of an essential part of FIG.

A centering device 7 for installing the indigo box 1 at a predetermined position in a through hole of a building wall includes a main body 6 and a scale 2 which is connected to the main body 6 and can detect a distance from the three-sided frame. Using a plumb bob 3 with a weight under the length of the piano wire and jack bolts 5a, 5b screwed on the top and bottom of the main body 6 holding the indie box 1, and using the scale 2 and the plumb bob 3. Thus, the indie box 1 can be installed at a predetermined position without inclining with respect to the vertical.

When the indigo box 1 is installed, the indigo box 1 is brought into contact with the main body 6 of the centering device 7 from the back side thereof, and the bolt 4 is inserted into the cover mounting screw hole of the indigo box 1.
The indigo box 1 is held by screwing and tightening a and b, and then the centering device 7 in a state of holding the indigo box 1 is temporarily mounted in the through hole for mounting the indigo box on the building wall, and the scale 2 While checking the distance from the three-way frame and floor and verticality with plumb bob 3, the jack bolt is expanded and contracted for positioning.

After that, the indigo box 1 is welded to a reinforcing bar or the like in the building wall, and after the welding is completed, the jack bolts 5a, 5b.
Is loosened, the bolts 4a and 4b are removed, and the centering device 7 is removed.

[0013]

As described above, according to the present invention,
The indigo box can be easily fixed to the building wall, and the indigo box can be positioned quickly and accurately. Further, it is possible to prevent the positional deviation from occurring after the centering and before the welding and fixing.
