DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will now be described in detail with reference to FIGS. 1 and 2. FIG. 1 and 2, reference numeral 1 denotes I
A base frame is formed by combining steel shapes in a cross-girder shape. At four corners of the base frame 1, there are attached columns P formed by laminating unit supports 2 each having a substantially square shape in a side view.

The unit support 2 is formed by connecting a pair of left and right vertical plates 2a, 2a facing each other with a side plate 2b to form a main body, and extending vertically above and below both ends of the main body in parallel with each other. A pair of connecting plates 3 and 3 are fixed. A bolt hole 3a penetrating through the connecting plate 3
Bolts 4 are passed through the unit supports 2 and 2
By connecting the connecting plates 3 and 3 to each other, the plurality of unit supports 2 are stacked to form the support P.

In the middle of the side plate 2b in the vertical direction, a pedestal 5 for receiving the entrance / exit frame W of the elevator.
Are fixed so as to extend horizontally. The height A from the upper surface of the receiving table 5 to the upper end surface of the unit support 2 is:
It is formed slightly larger (higher) than the thickness B of the doorway frame W.

A reinforcing plate 6 for connecting a pair of left and right vertical plates 2a is provided on a portion of the main body opposite to the receiving table 5. Further, a bolt hole (coupling portion) 7 is formed in a portion of the side plate 2b above the reinforcing plate 6.
Is pierced. Then, the bolt 8 inserted into the bolt hole 7 is screwed into the entrance frame W to directly couple the entrance frame W to the unit support 2.

A pillow bed 9 is attached to a lower portion of the base frame 1 so that the base frame 1 can be held horizontally. For example, a pipe 10 is bridged on the top of the second member 2. Then, a protective sheet 11 also serving as a makeup is attached to the pipe 10. The pillow bed 9
By installing the wheels 12 instead of the base frame 1, the base frame 1 on which the entrance frame W is placed can be smoothly moved.

Next, a description will be given of a procedure for transporting the entrance / exit frame W using the elevator entrance / exit frame transport apparatus of the present embodiment constructed as described above.

First, when transporting the entrance / exit frame W from a factory to an installation place of a high-rise building, the unit supports 2 are temporarily fixed to the four corners of the base frame 1 in the form of a girder using bolts 4. Next, the entrance / exit frame W is placed on the cradle 5 of these unit supports 2.
Is placed, and the entrance / exit frame W is directly connected to each unit support 2 using the bolt 8. Thereafter, the unit supports 2 are firmly fixed to the base frame 1 by tightening the bolts 4.

When transporting a plurality of entrance / exit frames W, another unit support 2 is sequentially stacked on the unit support 2 fixed on the base frame 1 as described above. Then, the unit supports 2 stacked vertically using the bolts 4 are firmly connected to each other, and the entrance / exit frame W placed on the receiving base 5 of each unit support 2 is fixed to each unit support using the bolts 8. It is firmly and directly connected to the body 2.

At this time, the unit supports 2 that are vertically stacked and that constitute the column P are firmly connected to each other using the bolts 4 and firmly connected to the entrance frame W using the bolts 8. You. Thereby, since each entrance / exit frame W plays a role of a reinforcing member for increasing the rigidity of the support P, the support P
Stiffness of the plurality of entrance / exit frames W
Can be firmly fixed on the base frame 1. Therefore, since no other reinforcing member, support frame, or the like is required to increase the rigidity of the column P, the structure of the transport device can be simplified. Further, the work of laminating the plurality of doorway frames W on the base frame 1 can be easily performed.

When the entrance / exit frame W fixed on the base frame 1 as described above is grounded to the installation place of the high-rise building, first, the unit support 2 supporting the uppermost entrance / exit frame W is required. Is separated from the unit support 2 thereunder. At this time, by separating the unit supports 2 stacked vertically, the entrance / exit frame W can be easily lowered from above the base frame 1. Further, since the unit support 2 is connected to the entrance frame W lowered from the base frame 1, the entrance frame W is horizontally placed on the floor without directly contacting the entrance frame with the floor. Can be mounted.

When the door frame W is sequentially lowered from the top of the base frame 1 in this manner, the columns P supporting the door frame W are disassembled into pieces. Thereby, when returning the transport device of the present embodiment to the manufacturing factory of the entrance / exit frame W,
Since the pillar P does not exist on the base frame 1, the transport efficiency when transporting this transport device can be greatly increased.

[0019]

That is, as is apparent from the above description, according to the transportation apparatus for an entrance frame of an elevator of the present invention, the columns can be disassembled by separating the unit supports from each other. Transportation efficiency when returning to the factory can be improved. Also, since the unit support is directly connected not only to the other unit supports and the base frame but also to the door frame, the door frame can be firmly supported without using other reinforcing means. In addition, the structure of the transport device can be simplified. Also, by connecting or separating the unit supports bonded to the doorway frame,
Work to assemble doorway frames together before starting transportation,
Also, the work of separating the doorway frames at the installation location can be easily performed. Further, since the vertical dimension of the unit support is larger than the thickness of the entrance frame, in a state where the unit support is coupled to the entrance frame, the entrance frame is not brought into contact with the ground or the like, and the entrance frame is grounded. And so on can be placed horizontally.
