Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of mounting a unit block of an elevator using a unit block in which a front frame, a hatch, a guide device therefor, and the like are integrated.

[0002]

2. Description of the Related Art Generally, a method of mounting and fixing a unit type elevator is to stack the units from bottom to top and to fix the fixing metal fittings provided on the units to the hoistway wall of the building.

[0003]

However, according to the above-mentioned conventional mounting and fixing method, all the self-weight of the unit is borne by the structural body of the unit, so that it is necessary to make the structure of the unit strong. As a result, the unit becomes heavier and difficult to transport, lift and install. Also, when the method of stacking units from bottom to top is used, the bottom unit becomes the standard, so the more floors in the building and the more units are stacked, the more installation error and the frames that make up the units. In addition to the distortion, the door-related parts attached to the unit also have an error, which necessitates centering and adjustment work.

An object of the present invention is to provide a method of mounting a unit block of an elevator using a unit block which can reduce the error in installation while reducing the weight.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention has a mounting member centered and mounted on a building wall at the entrance and exit of an elevator hoistway, and then mounted on the mounting member. A unit block having a frame structure including a front frame pre-centered and formed, a pair of guide devices provided above and below the front frame, and a hatch door opened and closed between the guide devices is supported and fixed. Is characterized by.

[0006]

In the mounting method of the unit block of the elevator according to the present invention, the unit block having the frame structure is supported and fixed to the mounting member provided at the entrance / exit portion of the hoistway as described above. This mounting member receives. Therefore, the weight of the unit block can be reduced. Also, since the centered unit block is attached to the correctly centered mounting member, installation error is extremely small and it is limited between the mounting member and the unit block. You can

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing a mounting member provided at an entrance / exit of a hoistway that adopts a method of mounting a unit block of an elevator according to an embodiment of the present invention. As shown in the figure, at the entrance / exit of each floor of the hoistway-side building wall 2, there is a mounting member 1 that is accurately centered in advance with respect to the building wall 2.
It is supported and fixed via a bracket 3 and a bolt 4. This mounting member 1 is. For example, it has a frame-shaped frame structure, and a plurality of brackets 6 for mounting unit blocks 5 to be described later are integrally formed on the respective squares. The bracket 6 has an elongated hole 7 extending in the horizontal direction, and a bolt 8 used for attaching and fixing the unit block 5 is preliminarily attached to the elongated hole 7. As shown in FIG. 2, which is an enlarged plan view of FIG. 1, since the plurality of brackets 6 are separated from the building wall 2 by a predetermined distance, the bolts 8 can be tightened thereafter.

FIG. 3 is a perspective view showing a unit block 5 on the side of a hatch door which adopts a method of mounting an elevator unit block according to an embodiment of the present invention. The unit block 5 attached to the attachment member 1 described above is a front frame 11 having a frame structure composed of a pair of vertical columns 9 and horizontal columns 10.
And a pair of guide devices 1 called a hatch sill and a pocket
2, 14 and a hatch door 13 which opens and closes between these guide devices 12, 14 are correctly centered in advance and integrally formed. The vertical pillar 9 of the front frame 11 is integrally formed with a plurality of brackets 15 at positions corresponding to the above-mentioned brackets 6, and these brackets 15 are formed with elongated holes 16 extending in the vertical direction. There is. Regarding the configuration of the front frame 11, for example, a part of the guide device 12 may be provided in the horizontal pillar 10
There are various conceivable examples such that the guide rail of the guide device 14 is also used as a member constituting the frame body of the front frame 11.

Next, the mounting method will be described. First,
The unit block 5 is opposed to the mounting member 1 fixed as shown in FIG. 1, the brackets 6 and 15 are positioned so as to fit, and the both are connected and fixed by the bolt 8 shown in FIG. At this time, when an installation error occurs between the mounting member 1 and the unit block 5, the unit block 5 is moved in the vertical and horizontal directions by using the long holes 7 and 16 of the brackets 6 and 15. Easy to adjust.

Since the frame-structured unit block 5 is fixed to the frame-structured mounting member 1 in this manner, the self-weight of the unit block 5 is supported by the mounting member 1 and therefore the unit block 5 is made stronger than necessary. It doesn't have to be, and can be made lightweight. Further, since the error in the installation of the unit block 5 is the installation error between the one unit block 5 and the one mounting member 1, the error can be suppressed to the minimum and the adjustment work can be easily performed. Further, the error in this case can be easily adjusted by loosening the bolt 8 and moving the unit block 5 to make the adjustment. Furthermore, since the unit block 5 and the mounting bracket 1 are units having a frame structure, they can be easily transported and carried into them.

FIG. 4 is a perspective view showing a unit block 5 on the hatch door side which employs a method of mounting a unit block of an elevator according to another embodiment of the present invention. Only parts different from the embodiment shown in FIG. 3 will be described. However, the other equivalents are given the same reference numerals and detailed explanations thereof are omitted. To the unit block 5 described above, a frame 17 configured to extend along the inner wall surface of the hoistway is integrally connected to the hoistway side of the vertical frame 9. A pair of guide rails 19 for guiding the car and a guide rail 18 for guiding the counterweight are fixed in the hoistway, and these guide rails 18, 19 are fixedly attached to the frame 17.
Therefore, by accurately centering the frame 17 to form the unit block 5, the guide rail 1
The mounting positions of 8 and 19 can be accurately determined.

Assembly is carried out in the same manner as in the previous embodiment with the frame 17 removed, and then the unit block 5
After mounting, the removed frame 17 is mounted on the vertical frame 9 of the unit block 5, and this time, the guide rails 18 and 19 are installed in the hoistway with the frame 17 as a reference. As can be seen from this description, since the unit block 5 centered accurately is used, the frame 17 added to the unit block 5 can be used to accurately install the guide rails 18 and 19. It is possible to obtain the same effect as that of the previous embodiment.

[0013]

As described above, according to the present invention, since the unit block having the frame structure is supported and fixed to the mounting member mounted on the hoistway wall, the weight of the unit block can be reduced, and the conventional structure can be realized. Compared to the above, the installation work can be performed more easily, and the error during installation is reduced,
Therefore, the adjustment work can be reduced and the efficiency of the installation work can be improved.
