In addition, as shown in FIG.
A suspending member 30 using a detachable eyebolt or the like is provided in the frame 20 in the 12B, and the floor 10 and the entire balcony are suspended by a crane or the like by hanging a wire 61 or the like on the portion. ing.

In this embodiment constructed as described above, the floor 10 and the entire balcony are attached to the steel frame 52 of the house 50 in the following procedure. First, in a factory, mounting surfaces 40B and 41B are formed on the skeleton 20 of the floor portion 10.
On the other hand, the box-shaped member 40A is mounted on the steel frame 52, and the mounting plate 41A is mounted on the column 53 (the state shown in FIGS. 5 and 6).

Next, at the construction site, after assembling the building 50, the columns 53 are erected, and then the balcony is attached. That is, the hook 62 of the 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 to be lifted (the state of FIG. 3).
Then, while moving the balcony, the box-shaped member 40 of the steel frame 52 is inserted into the guide hole 44B of the mounting surface 40B of the end surface of the floor 10.
Insert the A guide pin 44A. Further, the guide pins 46A of the mounting plate 41A of the column 53 are inserted into the guide holes 46B of the mounting surface 41B on the lower surface of the floor 10 (the state of FIG. 4). In this state, the floor 10 is supported by the steel frame 52 at the base end via the guide pin 44A and supported by the support 53 at the distal end.
The crane wire 61 is removed from the suspension member 30.

Subsequently, 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,
Further, the mounting plate 41A and the mounting surface 41B are tightened with bolts 47B to join the floor 10 and the support 53. Thus, the floor 10 is fixed, and thereafter, the openings 12, 12A, and 12B are covered with lids 13 having shapes corresponding to the openings 12, 12A, and 12B. Finally, a waterproof sheet is laid on the upper surface of the floor 10 or the like to be subjected to waterproof treatment.

According to this embodiment, the following effects can be obtained. That is, since the box-shaped member 40A for attaching the balcony projects forward from the outer wall material 55 of the house, the balcony does not easily come into contact with the outer wall material 55, so that the balcony can be installed without being obstructed by the outer wall material 55. I can do it. For this reason, the installation of the balcony becomes easy, and the time required for the installation work is reduced.

A nut 43 is provided on the inner back surface of the box-shaped member 40A.
A is welded and fixed in advance, so when installing the balcony, simply insert the bolt 43B from the balcony side and screw this bolt 43B into the nut 43A to form a box-shaped member.
40A can be attached to the balcony, which eliminates the need to position the nut 43A and the bolt 43B on the inner back surface of the box-shaped member 40A, thus facilitating the installation work.
Less time is required for work.

Further, the guide pins 44A and 46A provided on the box-shaped member 40A and the mounting plate 41A are combined with the guide holes provided on the mounting surfaces 40B and 41B of the steel frame 52 and the column 53.
The fitting position of the balconies is determined by inserting the balconies into 44B and 46B. Therefore, positioning can be easily and reliably performed. Further, since the balcony is temporarily fixed by the guide pins 44A and 46A, the wire 61 and the like of the crane can be removed when the positioning is completed. For this reason, subsequent workability is improved.

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

Further, the box-shaped member 40A and the column on the building 50 side
Guide pins 44A and 46A are provided on the mounting plate 41A on the 53 side, and guide holes 44B and 46B for inserting the guide pins 44A and 46A are provided on the corresponding mounting surfaces 40B and 41B of the floor 10. Whether to provide the pins is optional, and may be determined as appropriate in consideration of the workability of the transport and mounting work.

The present invention is not limited to the above embodiment, but includes the following modifications. That is, in the above 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 column 53 side,
Guide pins 44A, 46A on corresponding mounting surfaces 40B, 41B of floor 10
Are provided in the guide holes 44B and 46B, however, the guide pins on which side are provided are optional, and may be determined as appropriate in consideration of the workability of the transporting and mounting work.

Also, the balcony in which the floor 10 and the handrail 11 are integrally formed has been described. However, the present invention is not limited to this.
A balcony that separately manufactures and transports the handrail unit 10 and the handrail unit 11 and assembles it at a construction site may be used.

Further, in a cantilever type balcony where there is no support column 53 for supporting the vicinity of the tip of the balcony overhanging from the house 50, it goes without saying that the mounting surface 41B on the tip side of the floor 10 becomes unnecessary. However, in this case,
Since the floor portion 10 is not temporarily fixed only by the mounting portion on the house 50 side, it is necessary to work while the floor portion 10 is suspended until the box-shaped member 40A and the mounting surface 40B are fixed by the bolts 43B.

The openings 12, 12A,
The shape of 12B is completely arbitrary, and a shape with good workability may be selected and used. Further, in the above embodiment,
Although the hanging type installation using the crane has been described, the present invention is not limited to this, and the installation can be similarly performed when the balcony is installed using human power or another equipment.

[0031]

As described above, according to the balcony mounting structure of the present invention, the box-like member on the house side on which the balcony is mounted protrudes forward from the outer wall of the house, and is obstructed by this outer wall. Balcony can be installed without the need. For this reason, the installation of the balcony becomes easy, and the installation work can be performed quickly.
