(Figure d
When the construction of the building in the construction space is completed, the pin 12 of the upper support frame 7 is pulled out to release the locking relationship between the upper support frame 7 and the temporary mast 4, and then the electric motor 9 is driven. When the electric screw 6 is rotated in the reverse direction, the nut 8 rises alone along the temporary mast 4a as shown in FIG. 6e, and stops the rise of the nut 8 at the upper end of the temporary mast 4a as shown in FIG. 6f. Then, the upper support frame 7 and the temporary mast 4a are locked and connected by pins 12. FIG.
d to 6e, the electric motor 9 is slightly rotated,
The whole load of the temporary roof structure A is rearranged between the support frames 7 or 10 by slightly raising and lowering the nut 8, and the pins 12 of the support frame 7 or 10 released from the load and free are easily removed and inserted. Is what you do. The above operation is repeated to complete the building D on the desired floor.

As described above, in the process of building a building in which the upper floors are sequentially stacked, the building floor slabs 18 which are successively arranged above the temporary masts 4, 4a as shown in FIGS. The upper ends of 4n to 4n are constrained by a horizontal connecting member 19 for each building floor slab 18 and the like.

As shown in FIG. 9A, by constructing the temporary roof structure A such that both side end surfaces of the roof standard block 15 meet the upper inner surface of the both side wall standard block 3,
