Therefore, the floor 10 and the entire balcony are configured to be suspended by a crane or the like.

In the present embodiment thus configured, the floor 10 and the whole balcony are attached to the steel frame 52 of the house 50 by the following procedure. First, in the factory, the mounting surfaces 40B and 41B are formed on the frame 20 of the floor 10. On the other hand, the box-shaped member 40A is attached to the steel frame assembly 52, and the attachment plate 41A is attached to the support column 53 (the state shown in FIGS. 5 and 6).

Next, at the construction site, after the building 50 is assembled, the pillars 53 are erected, and then the balcony is attached. That is, a hook 62 of a wire 61 for hanging is hung on the hanging member 30 in the openings 12, 12B, and the wire 61 is hung on the hook 60 of the crane (state shown in FIG. 3). Then, while moving the balcony, the guide pin 44A of the box-shaped member 40A of the steel frame assembly 52 is inserted into the guide hole 44B of the mounting surface 40B at the end surface of the floor 10. Further, the guide pin 46A of the mounting plate 41A of the support column 53 is fitted into the guide hole 46B of the mounting surface 41B on the lower surface of the floor 10 (state shown in FIG. 4). In this state, the floor 10 is supported by the steel frame assembly 52 on the base end side through the guide pins 44A and on the tip end side by the support column 53, so that the wire 61 of the crane is removed from the suspension member 30.

Next, the box-shaped member 40A and the mounting surface 40B are tightened with bolts 43B to join the floor portion 10 and the steel frame assembly 52, and further, the mounting plate 41A and the mounting surface 41B are tightened with bolts 47B. The floor 10 and the pillar 53 are joined.

Finally, a waterproofing process such as laying a waterproof sheet on the upper surface of the floor 10 is finished.

According to this embodiment, the following effects can be obtained. That is, since the box-shaped member 40A for mounting the balcony projects forward from the outer wall material 55 of the house, the balcony is less likely to contact the outer wall material 55, which allows the balcony mounting work without being disturbed by the outer wall material 55. You can do it. Therefore, the balcony can be easily installed, and the time required for installation work can be reduced.

Further, since the nut 43A is welded and fixed in advance on the inner back surface of the box-shaped member 40A, when the balcony is attached, the bolt 43B is inserted from the balcony side to screw the bolt 43B into the nut 43A. The box-shaped member 40A can be attached to the balcony only by doing this, so that it is not necessary to position the nuts 43A and the bolts 43B on the inner back surface of the box-shaped member 40A, which facilitates the installation work and requires more work. I don't have much time.

Further, the guide pins 44A and 46A provided on the box-shaped member 40A and the mounting plate 41A are inserted into the guide holes 44B and 46B provided on the mounting surfaces 40B and 41B of the steel frame assembly 52 and the column 53, respectively. The fitting position determines the installation position of the balcony. Therefore, the positioning can be performed easily and surely. Further, since the balcony is temporarily fixed by the guide pins 44A and 46A, the wire 61 of the crane can be removed when the positioning is completed. Therefore, the workability thereafter is improved.

The present invention is not limited to the above-mentioned embodiment, but includes the following modifications. That is, in the above-described embodiment, the nut 43A is welded and fixed in advance on the inner back surface of the box-shaped member 40A, but the present invention is not limited to this, and the nut 43A is attached when the balcony is mounted on the box-shaped member 40A on site. The box-shaped member 40A may be pressed against the inner rear surface, and the bolt 43B may be inserted into and screwed into the box-shaped member 40A. However, the workability is better in the above embodiment.

Further, the guide pins 44A, 46A are provided on the box-shaped member 40A on the building 50 side and the mounting plate 41A on the support column 53 side, and the guide pins 44A, 46A are inserted into the mounting surfaces 40B, 41B of the corresponding floor portion 10 by fitting. Although the guide holes 44B and 46B are provided, which side the guide pin is provided is arbitrary and may be appropriately determined in consideration of workability of transportation and mounting work.

The present invention is not limited to the above-mentioned embodiment, but includes the following modifications. That is, in the above-described embodiment, the guide pins 44A and 46A are provided on the box-shaped member 40A on the building 50 side and the mounting plate 41A on the support column 53 side, and the guide pins 44A and 46A are mounted on the corresponding mounting surfaces 40B and 41B on the floor 10. Although the guide holes 44B and 46B to be inserted are provided, which side the guide pin is provided is arbitrary and may be appropriately determined in consideration of workability of transportation and mounting work.

Further, although the balcony in which the floor portion 10 and the handrail portion 11 are integrally formed has been described, the present invention is not limited to this, and the balcony in which the floor portion 10 and the handrail portion 11 are manufactured and transported separately and assembled at the construction site may be used. .

Further, it goes without saying that the mounting surface 41B on the tip side of the floor 10 is not necessary in a cantilever type balcony in which there is no support column 53 that supports the vicinity of the tip of the balcony protruding from the house 50. However, in this case, since the floor 10 is not temporarily fixed only by the mounting portion on the house 50 side, the floor 10 is suspended until the box-shaped member 40A and the mounting surface 40B are fixed by the bolt 43B. Need to work.

The shapes of the openings 12, 12A, 12B provided on the floor 10 are completely arbitrary, and a shape having good workability may be selected and used. Further, in the above embodiment, the hanging type installation using the crane has been described, but the present invention is not limited to this, and the same installation can be performed when installing a balcony using human power or other equipment. it can.
