Then, centering installation devices 40A and 40B are provided on the component gripping tool B4 facing the floor side entrance of the 190th floor of the work platform frame so as to face 34B. The centering installation devices 4OA, 40B are connected to the component gripping tools 34A, 34B, and are configured to be hydraulically movable in the direction of connection.

Next, the operation of the installation device configured as above will be explained. Guide rail t2. It is assumed that tz' has already been installed.

For example, when installing the necessary entrance/exit parts for the floor side entrance on the fifth floor, the work platform frame 19 is attached to the guide rail 12.
' as a guide to rise. At this time, if the guide rail is accurately fixed according to the standard, the guide rail is regarded as a vertical reference line, and the laser oscillator 17 does not need to oscillate the laser beam 18. However, if the laser base 18Fi is to be used when moving up using a guide rail as a guide, which requires readjustment after installation is complete.

When the work platform frame 19 is raised, the lower fixing device 25
．． 26 hydraulic telescopic lifting legs 27 and 28 are extended. The laser oscillator 17 and the light receiver on the workbench frame 19 are designed and arranged so as to substantially coincide with each other on a vertical line.

Next, the engaging piece 29A of the upper fixing device 24 is extended to clamp the guide rail 12, and the work platform frame 19 is fixed. In this state, the elevating legs 27.28 are retracted, and in the retracted position, the retaining pieces 29B and 29C are extended to extend the guide rail 12.12'.

It becomes a state away from P (Fig. 3). After that, the engagement piece 29A of the upper fixing device 24 is released from the guide rail 12,
Extend the lifting legs 27 and 28 again, then attach the upper fixing device &
24 is fixed to the guide rail 12. By repeating the above operations, the work platform frame 19 is raised to a position where the automatic construction device 31 faces the installation position of the anchor bolt 5 at the floor side entrance on the fifth floor. At this time, the upper fixing device 24 clamps the guide rail 12.12' with the guide rail 12/1liL and the lower fixing device ft25.26.

In this state, the hydraulic positioning device [22 is operated, and the plunger y23 is pushed against the hoistway wall rIijlW.

Then, the control device 21 calculates the horizontal movement direction and movement distance of the work platform frame 19 from the current value from the light receiver 20, sends respective signals to the control valve opening/closing circuit of each hydraulic positioning device 18, and controls each plunger 23. The work platform frame 19 is moved horizontally in two directions by adjusting the amount of overhang. This operation continues until the center of the receiver 20 coincides with the laser beam !8. Apply a predetermined pressure and lock to determine the vertical position.Of course, before starting this vertical positioning work, the work platform frame 19 must be set at the level 632.
Needless to say, the lifting legs 27 and 28 should be slightly moved so that the horizontal centering operation is completed. - When the above-mentioned horizontal centering and vertical positioning operations are completed, the upper fixing device 24 is held by the guide rail 12 by extending the engagement piece 29A. At this time, if the position of the mounting bracket (not shown) of the guide rail 12 is aligned with the stop position of the work platform frame 19, the holding pieces 29A, 29B, 2

After fixing the work platform frame 19, move the automatic construction lid 31 to the anchor bolt installation position and measure the horizontal distance from the work platform frame 19 to the hoistway wall surface 19 and the depth of the hole hole.
Drill a hole for anchor bolt 5. After drilling is completed, compressed air is blown from the same device to clean the hole, and the anchor bolt 5 is inserted into the hole and the driving operation is performed.

Next, transportation and installation of the entrance/exit parts will be explained.

After driving the anchor bolt 5, the component lifting device 33 is lowered to the floor where the doorway component 2 is being assembled, and the doorway component is placed thereon. In this embodiment, the mounting bracket 4 and the sill 6 are temporarily fixed, and the doorway frame 8 is lifted up by the component lifting tool 33 using the component grasping tools 34A and 34B of the component lifting tool 33.

At this time, the component lifting device 33 is raised along the guide rail 12 by the guide s35, so when the component lifting device 33, which will not be removed during hoisting, is hoisted to a predetermined position, the electric winch 39 Stopped and locked. This operation may be carried out, for example, by detecting when the stopper part 33 of the parts lifting device 33 engages with the work platform frame 19 at 9 o'clock, cutting off the power to the electric winch 39, and activating the controller.

After confirming that the control *1t21 has stopped the localization 1 of the component lifting tool 33 and stopped the electric winch 39, the centering installation device 4OA,
A command is issued to 40B to move the component lifting tool 330 until it touches the component grasping tools 34 and 34B. Then, the component graspers 34A, 34B are connected to the centering installation devices 4OA, 40B, and the component graspers 34A, 3
4B, and the component lifting tool 33 are disengaged from each other. and,
It was decided that the movement amount of the centering installation devices 4OA and 40B would be determined by calculating the position of the entrance/exit frame 8 using the control device 21, and then controlled by sending a signal to a hydraulic control circuit (not shown). The doorway frame 8 is moved so that it is located at the installation reference position close to the hoistway wall surface IW. After moving to a predetermined position, the temporarily fixed mounting bracket 4 is fixed to the anchor bolt 5, and the doorway frame 8 and the threshold 6 are fixed to the fixed companion mounting bracket 4. At this time, the positions of the entrance/exit frame 8 and the sill 6 are the reference positions supported by the centering and installation devices 4OA and 40B, and if the mounting bracket 4 is installed at any deviation from the position, use a spacer when fixing the mounting bracket 4. Do fAu intervene?
This can be dealt with by providing the mounting fitting 4 with a long hole that can absorb the above-mentioned deviation.

After installation of the entrance/exit parts, the centering installation device 14OA, 4
Apply ground pressure to 0B to confirm that the entrance/exit parts are fixed, then release the negative pressure and release the parts grips A34A and 34B.
Return the component lifting tool 33 to its normal position. Then, the connection with centering installation equipment #nOA and 40B is released to complete the installation of the entrance/exit parts on the fifth floor. Thereafter, by repeating these operations, the entrance/exit parts for all floors are installed.

As described above, according to the embodiment of the present invention, the work platform frame 19 can be raised and lowered,
The installation of the anchor bolts 5, the transportation of the entrance/exit parts, and the centering are performed mechanically using the work platform frame 19, and the centering work is automated. Entrance/exit frame 8. Only the threshold 6 needs to be fixed, and the work is simple and can be done in a short time. Furthermore, since this work can be performed on the work frame 19, safety is high even when working at high places.

Furthermore, since the device of this embodiment is equipped with elevating legs, there is no need to wait for the hoist to be installed in the machine room before performing the installation work, unlike in the conventional case.

By the way, in the above embodiment, the work is carried out using the guide rails 12 and 12' which require readjustment, but when the work platform frame 19 is raised, the work is carried out while readjusting the guide rails at the same time. You can also do that. In this case, the upper and lower parts are stuck! [124 to 26 do not rise while holding the guide rails 12 and 12', but are fixed to the hoistway wall with guide rail mounting brackets (
(not shown) so as to rise while maintaining K. Then, the guide rails for readjustment are grasped and positioned by centering devices 30A to 30D provided on the work platform frame 19, and fixed to the mounting bracket.

By the way, in the above embodiment, a laser beam is used as a vertical reference line, and there is no problem in using it by suspending a piano wire as in the conventional case.

Nine, the above embodiment uses hydraulic pressure to drive each device.
However, the content of the present invention does not change even if a rack-binion system or a motor gear system is used.

As explained above, according to the present invention, most of the installation work of entrance/exit parts can be mechanized, so the work time is shortened, and the operator's actions are limited to a small area. Since the work will be done on the workbench frame, it will be safe.

This has the effect of uniformizing the installation accuracy of entrance/exit parts with high-quality labor.
