It is fixed on the beam 8a of the steel column 1a one step above.

This operation is sequentially repeated for all the posts 2, and when the ascent of all the posts 2 is completed, the process proceeds to the ascending of the large roof frame 5, as shown in FIGS.

In this operation, first, as shown in FIG. 6A, the receiving frames 29, 34 of the upper and lower pin locking devices 26, 27 in the frame lifting mechanism 4 of all the posts 2 are fixed to the lock pins 3
6B, the lock pins 32 of the receiving frame 29 of the upper pin locking device 26 are pulled out from the through holes 31 of the outer post 6 and the receiving frame 29 is locked with the receiving frame 29, as shown in FIG. The locked state with the outer post 6 is released, and the load of the large roof frame 5 is received by the receiving frame 34 of the lower pin lock device 27, and in this state, as shown in FIG. At the same time, the receiving frame 29 of the upper pin lock device 26 is raised, and the entire large roof frame 5 is pushed up.

The lifting of the large roof frame 5 is not completed at this point, but the extension of the vertical special jack 28 raises the receiving frame 29 of the upper pin lock device 26, as shown in FIG. Then, the receiving frame 29 of the upper pin lock device 26 is locked to the outer post 2 by the lock pin 32 so that the upper pin lock device 26 bears the load of the large roof frame 5, and then the lower pin lock device Then, as shown in FIG. 6e, the vertical special jack 28 is contracted and the lower pin lock device 27 is pulled up to a predetermined height.

After the lower pin lock device 27 is pulled up to a predetermined height by the contraction of the vertical special jack 28, the receiving frame 34 of the lower pin lock device 27 is fixed to the outer post by the lock pin 36 as shown in FIG. Lock to 2,

As shown in FIG. 6g, by simultaneously extending the vertical special jacks 28 in the frame raising mechanisms 4 of all the posts 2, the receiving frames 29 of the respective upper pin lock devices 26 are raised, and the large roof frame 5 is pushed up to a predetermined height. .

[0034]

As described above, in the erection apparatus used in the construction method of the present invention, the post 2 has a post elevating mechanism 3 for elevating the post 2, and a post elevating mechanism 3 above the post 2. When the frame raising mechanism 4 for raising the frame 5 is separately provided, and the upper fixed arm device 9 and the lower fixed arm device 10 of the post raising mechanism 3 are respectively raised along the steel column 1, the frame raising mechanism is used. Since the lock state of the receiving frames 29, 34 of the upper and lower pin lock devices 26, 27 in 4 with the outer post 6 is released, the post lifting mechanism 3 can be raised without receiving the load of the frame 5 at all. Therefore, the post 2 can be raised smoothly, quickly and safely by computer control by a compact mechanism that is not so large as the post raising mechanism 3.

When raising the large roof frame 5,
Only the frame 5 with a large load is pushed up using the post 2 which has already completed the ascending movement and the post 2 in a stable state as a fulcrum. Compared with the various construction methods, the upward movement of the large roof can be performed more stably and safely by computer control.
