[0002]
[Prior art]
Conventionally, buildings in which accessories such as balconies are installed on the outer wall surface of the building are known, and various attachment structures for these accessories have been proposed.
[0003]
For example, a structure has been proposed in which a reinforcing material is provided on the outer wall in order to attach the balcony to the outer wall surface. (For example, refer to Patent Document 1).
[0004]
Moreover, the structure which supported the balcony with the bracket from the downward direction is proposed (for example, refer patent document 2).
[0005]
In addition, it is generally necessary to transport a plurality of box-shaped building units manufactured in advance at the factory to the construction site, and to attach accessories such as balconies overhanging from the outer wall using a unit method that assembles a plurality of building units at the building site. The pillars at the four corners are used.

Second Embodiment of the Invention
The second embodiment of the present invention will be described below with reference to the drawings. Parts that are the same as or equivalent to those in the first embodiment of the invention are given the same reference numerals, and detailed descriptions thereof are omitted.
[0061]
In the attachment structure of the attachment attached according to the first embodiment of the invention, the attachment is a cantilever type, and therefore, it tends to tilt forward particularly in a balcony with a large protruding size. Appearance problems may occur when the balcony is tilted forward.
[0062]
Further, in the balcony Ba in which the water gradient 43 is formed on the floor surface 42a of the floor finish 42 toward the outer wall surface 16 side (eave side) as shown in FIG. 11, a desired water gradient cannot be ensured due to the forward inclination. This may cause the problem.
[0063]
Here, the forward inclination is the height between the eaves-side floor frame 25 (referred to as the horizontal frame 25a) and the eaves-side floor frame 25 (hereinafter referred to as the horizontal frame 25b) arranged in parallel with the outer wall. Due to the difference, the horizontal (tilted state) is leveled along the longitudinal direction on the upper surface of the low-quality frame 25 (hereinafter referred to as the vertical frame 25c) horizontally mounted between the horizontal frames 25a and 25b. This can be confirmed by measuring.
[0064]
Even if there is no problem at the time of new construction, these problems may be inclined forward over time. In order to cope with a change with time in a large accessory installed on a floor such as a balcony, it is generally easy to adjust the forward tilt after attaching the accessory.
[0065]
Therefore, Embodiment 2 of the present invention proposes an attachment mounting structure that can easily adjust the forward tilt even after attachment.
[0066]
First, in the attachment mounting structure according to the embodiment of the present invention, as shown in FIGS. 13 and 14, a support member 32 for supporting the balcony Ba from below is provided, and the support member 34 and the floor frame of the balcony Ba are provided. 25 (gap generating means for generating a gap 53 between the horizontal frame 25b and the horizontal frame 25b). The gap generating means includes a plate 45 fixed to the horizontal frame 25b by welding, a back nut 48 fixed to the inside of the horizontal frame 25b, and a back nut 48 tightened on the upper surface of the support member 34. This is generally composed of an adjusting bolt 52 that presses up and pushes up the horizontal frame 25b, and a spacer 44 that is inserted into the gap.
[0067]
As shown in FIG. 15, the plate 45 includes a fixed portion 46 fixed to the horizontal frame 25b and a protruding portion 47 protruding on the eaves side. A through hole 46a is formed in the fixed portion 46, and a long hole 49 is formed in the protruding portion 47 in the longitudinal direction.
[0068]
The plate 45 has a fixed portion 46 fixed to the lower surface of the floor frame 25 b and is disposed so as to face the upper surface 34 a of the support member 34 together with the protruding portion 47.
[0069]
A through hole is also formed in the horizontal frame 25b by being positioned in the through hole 46a, and a back nut 48 is fixed inside the through hole.
[0070]
Further, as shown in FIG. 16, the entire screw bolt 50 is fixed to the front end of the support member 32 with the tail portion 50a facing upward by being welded to the end of the support member 32, and can be removed from the tail portion 50a. A cap 51 with a sharp tip is put on.
[0071]
In such a structure, as shown in FIG. 16, the floor frame 25 is placed on the support member 32 by inserting and fitting the tail portion 50 a into the long hole 49. The cap 51 is removed and the nut 54 is lightly fixed (the nut 54 may be fixed last). After fixing an accessory to a rod-like structural member (not shown) with a mounting bolt, the degree of forward tilt of the vertical frame 25c is confirmed using a level device.
[0072]
Here, when the forward inclination is confirmed, a gap 53 is generated between the support member 32 and the lateral frame 25b by screwing the height adjusting bolt 52 into the back nut 48 as shown in FIG. A spacer 44 is inserted into the gap 53 as shown in FIG. As shown in FIG. 13, if the spacer 44 is provided with a recess 44a at the center so as not to interfere with all the bolts 50 or the adjusting bolts 52, the spacer 44 can be easily inserted into the gap 53. The shape of the spacer 44 is not limited to this, and may be free. For example, it may be a two-divided spacer with a relief recess at the center.
[0073]
After inserting the spacer 44 having a thickness corresponding to the degree of the gap 53, the height can be adjusted by tightening nuts 54 to all the bolts 50 as shown in FIG. The adjustment bolt 52 may be removed as necessary.
[0074]
In the case of tilting forward with time, the flooring 42, other waterproofing materials, base materials, etc. are removed to expose the adjusting means, and the adjusting bolt 52 is tightened by loosening the nut 54, and FIG. In a similar manner, a gap 53 can be obtained between the horizontal frame 25b and the plate 45. Accordingly, the spacer 44 may be inserted into the gap 53 by the same operation as described above.
[0075]
Finally, after confirming the level (tilt state) with a leveler, the adjustment operation is completed.
[0076]
According to the attachment mounting structure as described above, the forward tilt can be adjusted both during and after attachment.
[0077]
【The invention's effect】
As described above, according to the first aspect of the present invention, it is possible to provide an attachment structure for an accessory such as a balcony that does not affect the attachment of the interior material. Further, according to the fifth aspect of the present invention, there is a practical effect that the forward tilt can be adjusted even when the accessory has a forward tilt or a forward tilt occurs.
