FIG. 12B is a side view showing the posture after the floor unit 240 is moved horizontally, and is a view from the same viewpoint as FIG. FIG. 12C is a side view showing a posture in which the floor unit 240 is rotated, and the viewpoint is the same as that in FIG. First, the floor unit 240 attached in the posture of FIG. 12A is horizontally moved along the horizontal slit 251 in a direction away from the building 1 as shown in FIG. As a result, the locking between the locking member 244 and the arm 250 on the side far from the building 1 of the floor unit 240 is released. Then, as shown in FIG. 12C, the floor unit 240 can be rotated counterclockwise using the rotation shaft member 252 as a rotation axis. Thereby, since the operator does not bear the load of the floor unit 240, the floor unit 240 can be moved and rotated with a small force.

  Next, the construction procedure of the balcony 210 of the present invention will be described. The construction procedure of the balcony 210 will be described with reference to FIGS. 13 and 7. FIG. 13 is a schematic view showing the construction procedures side by side in FIGS. 13 (a) to 13 (d). 7A and 7B are schematic diagrams focusing on the position where the scaffold is assembled, in which FIG. 7A is a top view and FIG. 7B is a front view. Although FIG. 7 is a figure referred also when demonstrating the balcony 10 of 1st embodiment, since the content is common, it refers also here.

  First, as shown in FIG. 13A, the arm 250 is attached to the housing of the building 1. This is the same as the conventional construction procedure, and the arm 250 is attached to the outer wall portion of the building 1 at a substantially right angle so as to protrude from the building 1 in a substantially horizontal direction. The number of arms to be attached can be increased or decreased as necessary in consideration of the width and weight of the balcony to be constructed. In the case of FIG. 13A, two arms 250 and 250 are attached. Construction is done so that the distance between the arms is approximately equal to the width of the balcony to be constructed.

  Next, the scaffold 60 is assembled. At this time, on the balcony 210, as shown in FIG. 13B, the arms 250 and 250 attached to the building as described above are used as the scaffold 60. That is, at this stage, the floor unit 240 is attached to the arms 250 and 250 to form a part of the scaffold. In the case of a two-story building, as shown in FIG. 7 (b), the scaffold has three levels of height: the height of the first floor, the height of the second floor, and the height of the second floor ceiling. Assemble. Among these, the floor unit 240 is used as a scaffold for the first floor height portion and the second floor height portion. Moreover, as shown in FIG. 7A, the scaffold 60 is assembled in a continuous shape so as to surround the periphery of the building 1. The scaffold 60 of the planned installation portion of the balcony 210 indicated by B in FIGS. 7A and 7B is a floor unit 240 attached on the arms 250 and 250.

  Next, the outer wall construction of the building 1 is performed using the scaffold 60 assembled as described above. At this time, it may be difficult to construct the outer wall of the part where the outer wall of the building 1 is in contact with the floor unit 240. In the balcony 210 of the present invention, as described above, the floor unit 240 can be rotated around an axis disposed substantially parallel to the wall of the building 1. Therefore, the floor unit 240 is rotated from a posture in which the floor unit 240 is horizontal. Then, as shown in FIG.13 (c), since a space can be made between the outer wall of the building 1 and the floor unit 240, construction of the outer wall of the building 1 can be performed.

  Then, as shown in FIG. 13D, after the outer wall construction of the building 1 is completed, the floor unit 240 is returned to the horizontal posture and fixed, and the other parts of the balcony 210 are constructed.

  As described above, according to the construction method of the present invention, since the floor unit 240 of the balcony 210 is used as a scaffold, it is not necessary to assemble the scaffold twice before and after installing the balcony as in the prior art. Therefore, it is possible to contribute to the reduction of scaffold installation cost, the removal cost of the scaffold, the reduction of the rental cost of the scaffold board, and the shortening of the construction period.

  While the present invention has been described in connection with embodiments that are presently the most practical and preferred, the present invention is not limited to the embodiments disclosed herein. However, it can be appropriately changed without departing from the scope or spirit of the invention that can be read from the claims and the entire specification, and a balcony with such a change is also understood to be included in the technical scope of the present invention.
