And has a structure that fits.

  Next, as shown in FIG. 13-A, the lowering operation of the inner frame 2d is basically the same as that of the outer frame 2c. First, connection / inspection of the operation panel and removal of the fixing pin 9 are performed. I do.

  Thereafter, the set value is further checked for any obstacles during movement, and the inner frame 2d is raised by 200 mm as an example. Therefore, the rotary block stopper 2n is removed, and the inner arm 2b is stored in the rotary block 2k. Again, the rotary block stopper 2n is inserted into the hole between the rotary block 2k and the arm 2a so that the stored arm 2b does not move.

  In this way, the inner arm portion 2b is retracted to the rotating block 2k side, and it is confirmed that there is no hindrance to the lowering of the inner frame 2d. Since the inner frame 2d is only included in the outer frame 2c, simultaneous descent and individual descent for each station are possible.

  Then, check the fixing height. For this purpose, as an example of the fixing position, the position is stopped 200 mm before. Therefore, the rotary block stopper 2n is removed and the inner arm 2b is taken out. Then, again, the rotating block stopper 2n is inserted through the hole between the rotating block 2k and the arm portion 2a, and fixed so that the arm portion 2a pulled out does not move.

  Then, a continuous descent operation is performed to a predetermined position. Since the inner arm 2b of the self-elevating external curing device 2 and the pin member 6a of the fitting bracket 6 in the fixing device 1 are fitted to the pin member and the pin hole, automatic alignment is performed and the work period is increased. Shortened. Since it is not a fitting structure with bolts and nuts fastened, it prevents the bolts from falling. Thereafter, the fixing pin 9 is inserted into the fixing pin hole 6m protruding upward from the inner arm portion 2b to fix the arm portion 2b.

  As shown in FIG. 14-A, the self-elevating type external curing device 2 descends like a worm from the upper floor of the building to be demolished by the outer frame 2c and the inner frame 2d. Note that the self-elevating external curing device 2 is not necessarily accompanied by a scaffold, but can be used as a curing device in which curing members are simply provided.

  In the middle of the lowering operation of the self-elevating type external curing device 2, as shown in FIG. 14-B, the level is detected by measuring the amount of rotation of the continuous ball nudge 2e. Is stopped, the device stops when the maximum load / minimum load set by the load measurement (load cell) of the ball screw 2e is exceeded, and the device stops when there is an overrun, etc. This is to make appropriate settings and confirmation from the operation GP screen.

  As described above, by the self-elevating system 15 using the self-elevating type external curing device 2 and the fixing device 1, the arms 2a and 2b of the self-elevating type external curing device 2 and the pin member 6a (6b) of the fixing device 1 are used. ) Is smoothly advanced, labor is not required, and since there is a taper portion, automatic alignment for alignment is performed, and quick fitting is achieved, thereby shortening the work period.

  Further, in the fixing device 1, the casing 1 a is surrounded and fixed to the pillar 3 to be disassembled. For example, with respect to a tensile force that separates from the pillar 3 due to a vertical load applied to the support bracket 1 d, As shown in 6-A, the support bracket 1d is prevented from rotating or sagging by surrounding the column 3 with the housing 1a. And the deformation | transformation is prevented because the support bracket 1d which protrudes from the pillar 3 becomes a frame integrally with the housing | casing 1a.

  Moreover, since the said fixing device 1 surrounds the pillar 3, it can also transmit a horizontal force. Since this fixing device 1 is diverted to the lower floor by the lowering of the self-elevating external curing device 2, the clearance is adjusted in the liner plate (push bolt) 7 or the adjusting member when dismantling or installing from the pillar 3. 8 can be easily adjusted.

  Moreover, in the assembly of the casing 1a of the fixing device 1, the size of the pillar 3 can be quickly accommodated by changing the bolt position. In this way, the self-elevating external curing device 2 can be held without assembling or installing the fixing device 1 without using a low-reliability welding method or the like.

  The self-elevating external curing device 2 and the fixing device 1 according to the present invention and the installation method thereof can be widely applied not only to building dismantling but also to new construction.
