In this case, the side of the building units 41a and 41e is one side in the direction of the short side, and the side of the building units 41c and 41g is the other side in the direction of the short side. Note that the configuration of the unit building is not limited to the above. Also, the balcony 4 may be installed along the direction of the long side (the direction of the girder) of the building units 41a to 41g.

The building units 41c and 41g on the other side are offset in the direction of the long side by the size of the balcony 4 with respect to the building units 41a and 41e on one side and the building units 41b and 41f on the middle side. there is As a result, the balcony 4 is installed so that the eaves side portion extends over (faces) the non-offset upper floor building units 41e and 41f, and the eaves side is almost identical to the offset building unit 41g. It is considered to be flush. In addition, the balcony 4 only needs to straddle the plurality of building units 41e and 41f, and does not need to extend over the entire area in the direction of the short side. In addition, the balcony 4 may be longer than the short side dimension of one of the building units 41e and 41f, for example, shorter than the short side dimension of the combined building units 41e and 41f. be able to.

Furthermore, under the other side (terrace section 53) of the balcony 4, a building unit 41d smaller than the others is installed so as to be continuous with the building unit 41b in the long side direction. The small building unit 41d is, for example, an entrance space having an entrance door 54 (FIG. 1). A space 51 facing the entrance door 54 under one side (porch portion 52) of the balcony 4 is used as an entrance porch or the like. In this case, an eaves is installed on the lower surface of the porch portion 52 of the floor portion 11 .

When installing the other side of the balcony 4 on the small building unit 41d, as shown in FIG. The small building unit 41d on the lower floor is inserted into a positioning pin 55 projecting upward from the small building unit 41d on the lower floor (the upper end of the pillar 42 of the lower floor small building unit 41d). The balcony 4 is suspended almost directly below at a position directly above the . After being lowered onto the small building unit 41d on the lower floor, the space between the other side of the floor 11 and the small building unit 41d is appropriately fixed with bolts in the vertical direction.

On the other hand, on one side of the floor portion 11, the lower portion of the corner portion 12 on the eaves side is fixed to the upper end portion of a balcony pillar 29 which is embedded and fixed in advance in the ground. For this purpose, a pin hole provided in a corner portion on the eaves side (on one side of the floor portion 11) is inserted vertically into a positioning pin 55 projecting upward from the upper end portion of the balcony pillar 29. , so that the balcony 4 is hung almost directly below. After hanging down onto the balcony pillar 29, bolts are vertically fixed between the corner portion on the eaves side (one side of the floor portion 11) and the balcony 4. - 特許庁

At this time, the balcony 4 is slightly tilted so that the other side faces downward so that the positioning pin 55 of the small building unit 41d on the lower floor fits into the pin hole before the positioning pin 55 of the balcony pillar 29. It is preferable to leave

In addition, above the lower floor building unit 41a located on one side (porch portion 52) of the floor portion 11, until the building fixing portion 15 of the balcony 4 is fixed to the upper floor building unit 41e, A receiving plate 57 (FIG. 11) for temporarily placing one side of the floor 11 is attached.

<Effects> According to this embodiment, the following effects can be obtained.

(Action and Effect 1) A balcony 4 may be installed on the upper floor portion 3 of the building body 1 . The floor portion 11 of the balcony 4 may have a building fixing portion 15 at one corner portion 12 for fixing to the upper floor portion 3 of the building body 1 perpendicularly. As a result, the balcony 4 can be attached such that one corner portion 12 of the floor portion 11 is fixed to the upper floor portion 3 of the building body 1 by the building fixing portion 15 so as to be perpendicular to the plane.

The floor section 11 may have a shape adjusting section 16 near the building fixing section 15 . As a result, when one corner portion 12 of the floor portion 11 is fixed to the upper floor portion 3 of the building body 1 perpendicularly, the shape adjustment portion 16 adjusts the shape of the portion near the building fixing portion 15 . can be done by Moreover, the shape adjustment portion 16 may have a bolt fastening portion 18 . Thereby, the shape adjustment part 16 can easily perform partial shape adjustment of the floor part 11 by loosening the bolt fastening part 18 .

Therefore, for example, the building fixing portion 15 provided on (one corner portion 12 of) the floor portion 11 of the balcony 4 is bolted to the mounting hole previously provided on the side surface of the upper floor portion 3 of the building body 1 . Partial fine adjustment of the shape of the floor part 11 by the shape adjusting part 16 when the position of the mounting hole and the hole part 15b of the building fixing part 15 do not match due to the positional deviation when mounting by 35. , the building fixing portion 15 can be corrected so as to match the position of the mounting hole of the building body 1, and the floor portion 11 (one corner portion 12 of) of the balcony 4 can be fixed to the building body 1 without hindrance. become able to.

At this time, the shape of the floor portion 11 can be partially adjusted only by loosening the bolt fastening portion 18 near the building fixing portion 15, and the position adjustment of the building fixing portion 15 is relatively easy. Balcony 4 alone can be aligned regardless of the position of the mounting hole.

Therefore, for example, when the balcony 4 is pre-assembled to the size of the completed form and installed and fixed to the building body 1, there is no need to adjust the building body 1 or the entire balcony 4, and the building is fixed. This is advantageous both in terms of structure and work because it is sufficient to adjust only the vicinity of the portion 15 . As a result, it is possible to shorten the construction period of the building, reduce the time and effort required for construction, and reduce costs.

Furthermore, the bolt fastening portion 18 may be provided with the co-rotation prevention portion 17 . As a result, when the bolt fastening portion 18 is tightened again after loosening the bolt fastening portion 18 and adjusting the position of the building fixing portion 15, the bolt fastening portion 18 is firmly fastened without loosening by the co-rotation prevention portion 17. can be reliably returned to

(Effect 2) The floor 11 of the balcony 4 may have a first beam 31 perpendicular to the building body 1 and a second beam 32 extending along the building body 1 . Then, the first beam 31 may integrally have the building fixing portion 15 at the end on the building body 1 side. Thereby, the first beam 31 can be directly fixed to the building body 1 by the building fixing portion 15 .

The extension part 33 projecting laterally along the building body 1 from the side part of the building fixing part 15 is overlapped with the end part of the second beam 32, and the bolt fastening part 18 is perpendicular to the building body 1. The shape adjusting portion 16 may be formed by fastening and fixing in any direction. As a result, by loosening the bolt 18a and the nut 18b of the bolt fastening portion 18 and shifting the positions of the extension portion 33 and the end portion of the second beam 32, the first beam 31 having the building fixing portion 15 and the Since the lateral positional relationship with the second beam 32 changes, the shape of the floor 11 can be partially adjusted.

The co-rotation prevention part 17 may have a co-rotation prevention plate 17a arranged in contact with the surface of the extension part 33 on the building body 1 side. In this way, by using the co-rotation prevention plate 17a disposed in contact with the surface of the extension 33 on the side of the building body 1 as the co-rotation prevention portion 17, the extension 33 has a co-rotation prevention function. Only by installing the plate 17a, the co-rotation preventing portion 17 can be set in the vicinity of the building fixing portion 15 easily and reliably.

Further, the co-rotation prevention plate 17a may restrict the rotation of one of the bolt 18a passing through the extension 33 and the end of the second beam 32 and the nut 18b screwed to the bolt 18a. As a result, even if one of the bolt 18a or the nut 18b is sandwiched between the building body 1 and the floor 11 and cannot be touched by installing the balcony 4 with respect to the building body 1, Co-rotation prevention plate 17a can reliably prevent co-rotation of either bolt 18a or nut 18b.

(Effect 3) The co-rotation preventing plate 17a may have a rotation restricting portion 17b that presses the peripheral surface of one of the bolt 18a and the nut 18b to restrict rotation. As a result, the rotation of one of the bolt 18a and the nut 18b can be regulated with a simple structure in which the rotation restricting portion 17b is provided on the co-rotation preventing plate 17a, and the co-rotation of the bolt 18a and the nut 18b can be reliably prevented. can be done. Therefore, for example, it is not necessary to weld one of the bolt 18a and the nut 18b to the co-rotation prevention plate 17a.

(Effect 4) The building body 1 may be configured by building units 41a to 41g. As a result, the building body 1 can be constructed in a short period of time simply by manufacturing the building units 41a to 41g in advance at the factory and assembling them at the construction site. Then, as described above, the building body 1 composed of the building units 41a to 41g is assembled in advance to the size of the completed form to form a single structure, and the side surface of the upper floor portion 3 of the building body 1 is constructed. To shorten the construction period and reduce the cost of a unit building by adopting a structure in which the floor part 11 (one corner part 12 of the balcony 4) installed at a position is fixed to the building body 1 vertically. can be done. At this time, since the fixing of the building fixing portion 15 of the floor portion 11 of the balcony 4 to the building body 1 (the mounting hole provided in advance in the building) is a connection between large-sized objects that have already been installed, there is no misalignment. However, even if such a positional deviation occurs, by providing the shape adjustment portion 16 and the like near the building fixing portion 15, the building unit 41e and the floor portion 11 of the balcony 4 positional deviation from the building fixing part 15 can be easily corrected and fixed securely.

(Effect 5) The balcony 4 may extend from one side to the other side of the building body 1 so as to straddle the plurality of building units 41a to 41g. Thereby, a relatively large balcony 4 can be installed in the unit building.

The balcony 4 may have a porch portion 52 with a space 51 underneath on one side and a terrace portion 53 with a building unit 41d on the other side. The building fixing portion 15 may be installed at the corner portion 12 on the porch portion 52 side. As a result, a new balcony 4 having a configuration different from a porch balcony whose entire bottom is a space 51 and a terrace balcony whose entire bottom is a building unit can be obtained, and the installation structure of the balcony 4 for the unit building. can be diversified.

The other side of the newly constructed balcony 4 is fixed vertically to the lower building unit 41d, and one corner portion 12 on one side is perpendicular to the side surface of the upper floor building unit 41e. (horizontal direction). A balcony 4 assembled into one structure) is installed from above, and then the upper floor building units 41e to 41g are layered and fixed on the lower floor building units 41a to 41c, and finally the balcony. 4 is fixed to the side surface of the building unit 41e on the upper floor.

Therefore, the upper floor building units 41e to 41g are only vertically positioned and fixed to the lower floor building units 41a to 41c. For example, since it is not possible to adjust the position of the building units 41e to 41g on the upper floor by sliding it sideways, one corner portion 12 of the balcony 4 with respect to the building unit 41e on the upper floor cannot be adjusted. Fixing in the perpendicular direction (horizontal direction) is susceptible to positional deviation.

In this way, even if it is in a state where it is easily affected by positional deviation, as in this embodiment, the floor 11 of the balcony 4 (one corner 12) is provided in the vicinity of the building fixing part 15 provided. By providing a shape adjustment portion 16 (bolt fastening portion 18 having a co-rotation prevention portion 17) so that the shape of the floor portion 11 can be partially adjusted, the balcony 4 can be connected to the building unit 41e on the upper floor without hindrance. It becomes possible to fix to ~41g.
