The rotation restricting portion 17b may be a locking claw partially provided on one or both side edge portions of the co-rotation prevention plate 17a instead of the flange portion.

(4) As shown in FIG. 1, the building body 1 may be composed of building units 41a to 41g.

Here, the building units 41a to 41g are box-shaped structures manufactured in advance at the factory. A building (unit building) is constructed in a short period of time by transporting the building units 41a to 41g to the construction site and assembling them. The building units 41a to 41g include steel-framed ones and wood-based ones, and either of them may be used. In this example, it is a steel frame system. In the steel-framed building units 41a to 41g, the lower ends of the four metal columns 42 are connected by four metal floor beams 43 (FIG. 4), and the four metal columns 42 are connected. It has a rectangular unit frame in which the upper ends are connected by four metal ceiling beams 44 (FIG. 11).

In such a unit building, as shown in FIG. 10 (to FIG. 12), the lower floor building units 41a to 41d are installed on the foundation, and the lower floor building units 41d are assembled in advance to the size of the completed building. The balcony 4 (which was regarded as one structure) was installed from above, and then the building units 41e to 41g on the upper floor were laminated and fixed on the building units 41a to 41c on the lower floor, and finally the floor of the balcony 4 was fixed. It is preferable to assemble the corner portion 12 on one side of the portion 11 by a construction procedure such as fixing it to the side surface of the building unit 41e on the upper floor. When the upper floor building units 41e to 41g are laminated and fixed on the lower floor building units 41a to 41c, the portion of the outer wall of the upper floor building units 41e to 41g that interferes with the balcony 4 is appropriately arranged. Make sure to cut out (notch 46, FIG. 10).

(5) The balcony 4 may extend from one side of the building body 1 to the other side so as to straddle between the plurality of building units 41a to 41g.
One side of the balcony 4 may be a porch portion 52 having a space 51 below, and the other side may be a terrace portion 53 having a building unit 41d below.
The building fixing portion 15 may be installed on the side of the pouch portion 52.

Here, the building (unit building) may have any configuration, but in this embodiment, a plurality of building units 41a to 41c and 41e to 41g are arranged side by side in the direction of the short side (wife direction). It has a configuration in which balconies 4 are installed along the short sides. 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. The configuration of the unit building is not limited to the above. Further, the balcony 4 may be installed along the direction of the long side (girder direction) of the building units 41a to 41g.

Then, the building units 41c and 41g on the other side are arranged so as to be 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 the one side and the building units 41b and 41f in the middle. There is. As a result, the balcony 4 is installed so that the eaves side portion extends (faces) between the non-offset upper floor building units 41e and 41f, and the eaves side is substantially offset from the building unit 41g. It is said to be flush. The balcony 4 may extend between 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. Further, the balcony 4 may be longer than the dimension in the direction of the short side of one of the building units 41e and 41f, and is shorter than the dimension of the combined short side of the plurality of building units 41e and 41f, for example. be able to.

Further, under the other side (terrace portion 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 direction of the long side. The small building unit 41d is, for example, an entrance space having an entrance door 54 (FIG. 1). Further, the space 51 facing the entrance door 54 under one side of the balcony 4 (the porch portion 52) is regarded as an entrance porch or the like. In this case, an eaves ceiling is installed on the lower surface of the pouch portion 52 of the floor portion 11.

When the other side of the balcony 4 is installed on the small building unit 41d, as shown in FIG. 12, the other side of the balcony 4 is provided in the corner portion 12 on the other side of the floor portion 11 of the balcony 4 lifted by the crane. The small building unit 41d on the lower floor is inserted vertically into the positioning pin 55 projecting upward from the small building unit 41d on the lower floor (the upper end of the pillar 42). The balcony 4 should be hung almost directly below at a position directly above. After hanging onto the small building unit 41d on the lower floor, the other side of the floor 11 and the small building unit 41d are appropriately bolted 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 the balcony pillar 29 which is buried and fixed in the ground in advance. Therefore, the pin holes provided in the corners on the eaves side (on one side of the floor 11) are vertically inserted into the positioning pins 55 projecting upward from the upper end of the balcony pillar 29. , The balcony 4 is hung almost directly below. After hanging onto the balcony pillar 29, the corner portion on the eaves side (on one side of the floor portion 11) and the balcony 4 are bolted in the vertical direction.

At this time, the balcony 4 is slightly tilted so that the other side is 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 keep it.

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

<Action / Effect> According to this example, the following action / effect can be obtained.

(Action effect 1) A balcony 4 may be installed on the upper floor portion 3 of the building body 1. Then, the floor portion 11 of the balcony 4 may have a building fixing portion 15 for fixing the building body 1 directly to the upper floor portion 3 at one corner portion 12. As a result, it becomes possible to attach the balcony 4 so that one corner portion 12 of the floor portion 11 is fixed to the upper floor portion 3 of the building main body 1 directly by the building fixing portion 15.

The floor portion 11 may have a shape adjusting portion 16 in the vicinity of the building fixing portion 15. As a result, when the floor portion 11 fixes one corner portion 12 of the floor portion 11 directly to the upper floor portion 3 of the building body 1, the shape adjusting portion 16 adjusts the shape of the portion near the building fixing portion 15. Can be done by. Further, the shape adjusting portion 16 may have a bolt fastening portion 18. As a result, the shape adjusting portion 16 can easily partially adjust the shape of the floor portion 11 by loosening the bolt fastening portion 18.

Therefore, for example, the building fixing portion 15 provided on the floor portion 11 (one corner portion 12) of the balcony 4 is bolted to the mounting hole provided in advance on the side surface of the upper floor portion 3 of the building body 1. When mounting at 35, if the mounting hole and the hole 15b of the building fixing portion 15 do not match due to misalignment, the shape adjusting portion 16 partially fine-tunes the shape of the floor portion 11. Then, the building fixing portion 15 can be modified so as to match the position of the mounting hole of the building main body 1, and the floor portion 11 (one corner portion 12) of the balcony 4 can be fixed to the building main body 1 without any trouble. become able to.

At this time, the shape of the floor portion 11 can be partially adjusted by simply loosening the bolt fastening portion 18 in the vicinity of the building fixing portion 15, and the position of the building fixing portion 15 can be adjusted relatively easily. Regardless of the position of the mounting hole, the balcony 4 can be adjusted by itself.

Therefore, for example, when the balcony 4 is assembled in advance to the size of the completed form and installed and fixed to the building body 1, it is not necessary to adjust the building body 1 or the entire balcony 4 and fix the building. Since it is only necessary to adjust the vicinity of the portion 15, it is structurally and work-wise advantageous. As a result, it becomes possible to shorten the construction period of the building, reduce the labor of construction, and reduce the cost.

Further, the bolt fastening portion 18 may include a co-rotation prevention portion 17. As a result, when the bolt fastening portion 18 is loosened to adjust the position of the building fixing portion 15 and then the bolt fastening portion 18 is tightened again, the co-rotation prevention portion 17 tightens the bolt fastening portion 18 without loosening. Can be reliably returned to.

(Action Effect 2) The floor portion 11 of the balcony 4 may have a first beam 31 which is flush with 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 portion on the building body 1 side. As a result, the first beam 31 can be directly fixed to the building body 1 by the building fixing portion 15.

The extension portion 33 projecting laterally from the side portion of the building fixing portion 15 along the building body 1 and the end portion of the second beam 32 are overlapped with each other, and the bolt fastening portion 18 is flush with the building body 1. The shape adjusting portion 16 may be formed by fastening and fixing in the desired direction. As a result, the bolts 18a and nuts 18b of the bolt fastening portion 18 are loosened, and the positions of the extension portion 33 and the end portion of the second beam 32 are displaced so that the first beam 31 having the building fixing portion 15 and the first beam 31 Since the lateral positional relationship with the second beam 32 changes, the shape of the floor portion 11 can be partially adjusted.

The co-rotation prevention portion 17 may have a co-rotation prevention plate 17a arranged in contact with the surface of the extension portion 33 on the building body 1 side. In this way, by making the co-rotation prevention portion 17 a co-rotation prevention plate 17a arranged in contact with the surface of the extension portion 33 on the building body 1 side, the co-rotation prevention portion 33 has a co-rotation prevention function. By simply installing the plate 17a, the co-rotation prevention portion 17 can be easily and surely set in the vicinity of the building fixing portion 15.

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

(Action / Effect 3) The co-rotation prevention plate 17a may have a rotation restricting portion 17b that regulates rotation by pressing one peripheral surface of the bolt 18a and the nut 18b. As a result, the rotation of one of the bolt 18a and the nut 18b is regulated by simply providing the rotation restricting portion 17b on the co-rotation prevention plate 17a, and the co-rotation of the bolt 18a and the nut 18b is surely prevented. Can be done. Therefore, for example, it is possible to eliminate the need to weld and fix one of the bolt 18a and the nut 18b to the co-rotation prevention plate 17a.

(Action effect 4) The building body 1 may be composed of 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 main body 1 composed of the building units 41a to 41 g is assembled in advance to the size of the completed form to form one structure, and the side surface of the upper floor portion 3 of the building main body 1 is formed. By adopting a structure in which the floor portion 11 (one corner portion 12) of the balcony 4 installed at the position is fixed directly to the building body 1, the construction period of the unit building can be shortened and the cost can be reduced. Can be done. At this time, the fixing of the building fixing portion 15 of the floor portion 11 of the balcony 4 to the building main body 1 (mounting hole provided in advance) is a connection between large objects that have already been installed, so that the position is displaced. However, even if such a positional deviation occurs, the building unit 41e and the floor portion 11 of the balcony 4 can be provided by providing the shape adjusting portion 16 or the like in the vicinity of the building fixing portion 15. The positional deviation from the building fixing portion 15 of the building can be easily corrected so that the building can be securely fixed.

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

The balcony 4 may be a porch portion 52 having a space 51 below on one side and a terrace portion 53 having a building unit 41d on the other side. The building fixing portion 15 may be installed at the corner portion 12 on the side of the pouch portion 52. As a result, it is possible to obtain a new balcony 4 having a different configuration from the porch balcony in which the entire lower part is a space 51 and the terrace balcony in which the entire lower part is a building unit, and the installation structure of the balcony 4 for the unit building. Can be diversified.

The other side of the balcony 4 having this new configuration is fixed in the vertical direction with respect to the lower building unit 41d, and one corner portion 12 on one side is in the direction perpendicular to the side surface of the upper building unit 41e. It will be fixed in the (horizontal direction), but with this structure, the construction procedure is to install the building units 41a to 41d on the lower floor on the foundation, and to the building unit 41d on the lower floor (the size of the completed form in advance). The balcony 4 (which was assembled into one structure) was installed from above, and then the upper floor building units 41e to 41g were laminated and fixed on the lower floor building units 41a to 41c, and finally the balcony. One corner portion 12 on one side of 4 is fixed to the side surface of the building unit 41e on the upper floor.

Therefore, the building units 41e to 41g on the upper floor are only positioned and fixed in the vertical direction with respect to the building units 41a to 41c on the lower floor, and the balcony 4 previously installed on the building unit 41d on the lower floor. 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 direction perpendicular to the plane (horizontal direction) is easily affected by misalignment.

In this way, even if the state is easily affected by the positional deviation, as in this embodiment, in the vicinity of the building fixing portion 15 provided on the floor portion 11 (one corner portion 12) of the balcony 4. By providing the shape adjusting portion 16 (bolt fastening portion 18 provided with the co-rotation prevention portion 17) so that the shape of the floor portion 11 can be partially adjusted, the balcony 4 can be moved to the building unit 41e on the upper floor without any trouble. It can be fixed to ~ 41 g.
