The floor section 21 has a floor frame as a basic structure. The floor frame is composed of a pair of parallel eaves base beams 23 and eaves eaves beams 24 and a pair of parallel end beams 25 connecting the ends of the eaves base beams 23 and eaves eaves beams 24 . Inside the floor frame, a plurality of rafters 26 parallel to the end beams 25 are installed at intervals in the extending direction of the eave base beams 23 and the eaves edge beams 24 . The ends of the rafters 26 are fixed to the inner surfaces of the eaves base beam 23 and the eaves base beam 24 . A floor panel or the like is appropriately installed above the floor frame and rafters 26 .

Moreover, the handrail part 22 has a handrail frame as a basic structure. Inside the handrail frame, a lattice, a panel, a wall, and the like are appropriately installed according to the specifications of the balcony 4 . The handrails 22 are provided on three sides excluding the side of the eaves, or on two sides excluding one side.

In this case, the balcony 4 is installed in the building main body 1 in a state in which at least the floor frame constituting the floor portion 21 is pre-assembled to the size of the completed shape to form a large-sized structure (Figs. 11 to 13). ). At this time, the handrail frame may be integrally attached to the floor frame.

The floor portion 21 of the balcony 4 is installed at the lower portion of the upper floor portion 3 of the building body 1 (slightly above the upper portion of the lower floor portion 2). The floor portion 21 of the balcony 4 is fixed to the lower portion of the upper floor portion 3 of the building body 1 by a building fixing portion 28 provided at one corner portion 27 on one side. At this time, a shape adjustment portion 29 is provided in the vicinity of the building fixing portion 28 on the floor portion 21 . The shape adjustment portion 29 may be a bolt fastening portion or the like having a co-rotation prevention portion.

The balcony 4 may have a size that covers the entire side surface of the building body 1 from one side to the other side, but may be smaller than that.

Space 11 can be, for example, an entrance porch.
In the porch portion 12, an eaves ceiling material 31 is installed on the lower surface side of the floor portion 21, as shown in FIGS. The eaves ceiling material 31 is made of a fireproof material, and has a fixed ceiling support beam 32 installed parallel to the rafters 26 inside the floor section 21, and a fixed ceiling support beam 32 on the underside of the fixed ceiling support beam 32 that intersects with the fixed beam 32. It is attached via a ceiling support bar 33 fixed so as to do so. At the edge of the eaves material 31, for example, a viewing material such as a long eaves edge viewing material 34 extending along the edge of the eaves material 31 on the building body 1 side is installed.

As shown in FIG. 1 , the building section 13 may be provided continuously with the building body 1 or may be provided separately from the building body 1 . In this embodiment, the building section 13 is an entrance space or the like attached to the building body 1 so as to partially protrude from the building body 1 . The building section 13 has an entrance door 13a at a position facing the space 11 under the porch section 12 .
The terrace section 14 is formed on the upper portion of the building section 13 .

As shown in FIG. 6, the upper portion of the lower floor portion 2 is positioned slightly below the position of the lower portion of the upper floor portion 3 where the floor portion 21 of the balcony 4 is installed.

The receiving plate 15 holds the porch 12 on one side of the floor 21 until one corner 27 (building fixing portion 28) on one side of the balcony 4 is fixed to the upper floor portion 3 of the building body 1. , is a member for temporarily placing on the upper part of the lower floor part 2 of the building body 1. - 特許庁

For example, as shown in FIG. 4, the receiving plate 15 is provided near the position of the boundary portion 35 between the porch portion 12 and the terrace portion 14 and the building fixing portion 28 of the balcony 4 (opposite to the boundary portion 35). One or more is provided for the vicinity of the position of the side). The position of the receiving plate 15 may be set according to the size of the balcony 4. For example, as shown in FIG. The receiving plate 15 is constructed relatively thick so as to have the required strength.

As shown in FIG. 5, the support surface 15a is a surface on the tip side of the receiving plate 15 that protrudes from the building body 1. As shown in FIG. The receiving plate 15 is fastened and fixed to the upper part of the lower floor portion 2 of the building body 1 in the vertical direction with fasteners 36 such as bolts and nuts at the mounting base portion 15b on the base end side. The support surface 15a and the mounting base 15b are horizontally continuous in a flush state.

As shown in FIG. 7 (FIG. 8), the spacer 16 is interposed between the support surface 15a and the lower part of the floor 21 (of the eaves beam 23) of the balcony 4 to adjust the height of the floor 21. It is for doing The spacer 16 can be formed thinner than the receiving plate 15 . After temporary placement, the spacer 16 is vertically fastened to the eaves beam 23 of the floor 21 of the balcony 4 with fasteners 37 such as bolts and nuts.

(2) As shown in FIG. 5 or FIG. 8, the spacer 16 may be wider than the support surface 15a of the receiving plate 15 and project laterally from the support surface 15a (side projecting portion 16a). ).

Here, the spacer 16 can firstly be widened to protect the support surface 15a. In addition, the spacer 16 can be widened to adjust the peripheral state of the support surface 15a.

That is, for example, as can be seen from the comparison of FIGS. The eaves edge cutting member 34 installed along the edge of the eaves interferes with the receiving plate 15 . For this reason, it is necessary to provide a notch 38 (FIG. 7) slightly larger than the width of the support surface 15a in advance in the eaves edge part 34 where it interferes with the receiving plate 15 to prevent interference.

As shown in FIG. 6 (FIG. 9), the eaves edge parting member 34 has a substantially U-shaped fitting portion 34a in a side view that fits into the edge of the eaves ceiling material 31, and an upper part of the fitting portion 34a. It mainly has a mounting surface 34b for mounting in the vertical direction with fasteners 41 such as screws on the lower part of the base beam 23. As shown in FIG. The mounting surface 34b is bent substantially horizontally toward the eaves. In addition, at the position of the fitting portion 34a on the side opposite to the eaves ceiling material 31, the wall material 42 is in contact with the upper side surface of the wall material 42 (wall portion) attached to the lower floor portion 2 of the building body 1. A sealing member 34c is attached to seal between the The wall material 42 is made of fireproof material.

Further, an overlapping surface 34d extending laterally toward the wall member 42 is provided between the fitting portion 34a and the mounting surface 34b. This overlapping surface 34d extends substantially horizontally beyond the upper end of the wall material 42 to the extent that it almost reaches the position of the inner surface of the iron frame 42a installed on the inner surface of the wall material 42. . The overlapping surface 34d covers the upper side of the fireproof material 43 that expands with heat and is placed between the upper end of the wall material 42 and the iron frame 42a, and faces the fireproof material 43. As shown in FIG. The fireproof material 43 has a thickness that may or may not reach the overlapped surface 34d, and exerts fireproof performance by being thermally expanded and pressed against the overlapped surface 34d. The overlapping surface 34d and the fireproof material 43 form a fireproof line on the eaves side of the porch portion 12. As shown in FIG.

As described above, the overlapping surface 34d and the mounting surface 34b of the eaves edge cutting member 34 are notched at the portion that interferes with the receiving plate 15 to be wider than the supporting surface 15a of the receiving plate 15, so that the cutout portion 38 is formed. It's becoming Therefore, there is a possibility that the fire prevention line is cut off on the eaves side of the porch portion 12 at the position of the notch portion 38 .

Therefore, the spacer 16 is made wider than the width dimension of the notch 38 so that the side projecting portion 16a of the spacer 16 allows the gap between the support surface 15a of the receiving plate 15 and the edge of the notch 38 of the overlapping surface 34d. The notch 38 can be closed by bridging the . This makes it possible to prevent the fire prevention line on the eaves side of the porch portion 12 from being cut at the position of the notch portion 38 .

(3) As shown in FIG. 10 , a waterproof material 51 may be installed on the upper surface of the mounting base 15 b of the receiving plate 15 with respect to the building body 1 .

Here, the waterproof material 51 may be of any kind, and for example, a band-shaped waterproof tape or the like may be used to attach the waterproof material 51 . It is preferable that the length of the waterproof tape slightly exceeds the mounting base 15b. A step formed between the mounting base 15b and the portion beyond the mounting base 15b is preferably caulked to fill the step (caulking portion 52). Further, it is preferable to attach a waterproof material such as a waterproof sheet 53 to the upper surface (head) of the fastener 36 attached to the attachment base 15b.

In addition, as shown in FIG. 6 , a waterproof material 54 is provided between the lower floor portion 2 and the upper floor portion 3 of the building body 1 except for the receiving plate 15 . to form a waterproof line on the side. Then, as shown in FIG. 7 , by installing a waterproof material 51 on the upper surface of the receiving plate 15 , the waterproof line is not interrupted by the receiving plate 15 .

(4) As shown in FIG. 1 (FIG. 2), the building body 1 may be composed of building units 61a to 61g.
The balcony 4 may extend across the plurality of building units 61a to 61g.

Here, the building units 61a to 61g are box-shaped structures manufactured in advance at a factory. By transporting the building units 61a to 61g to the construction site and assembling them, a building (unit building) is constructed in a short period of time. The building units 61a to 61g include steel-framed units and wood-based units, and either of them may be used. In this embodiment, a steel-frame system is used. As shown in FIG. 4, the steel-frame building units 61a to 61g connect the lower ends of four metal columns 62 with four metal floor beams 63 (FIG. 6). It has a rectangular parallelepiped unit frame in which four metal ceiling beams 64 are connected between the upper ends of metal columns 62 .

The building (unit building) may have any configuration, but in this embodiment, as shown in FIG. It has a configuration in which a balcony 4 is installed along the short side.

As a result, the balcony 4 is installed so that the eaves side of the balcony 4 extends over (faces) the building units 61e and 61f on the upper floor which are not offset, and is substantially flush with the building unit 61g whose eaves side is offset. ing.

In addition, the balcony 4 only has to straddle the plurality of building units 61e and 61f, and does not need to extend over the entire area in the direction of the short side. Also, the balcony 4 may be longer than the short side (or long side) dimension of one of the building units 61e and 61f. It may be shorter than the dimension in the direction (or the direction of the long side).

Furthermore, under the other side of the balcony 4 (terrace section 14), as the building section 13, a building unit 61d smaller than the others is installed so as to be continuous with the building unit 61b in the direction of the long side. there is

When installing the other side of the balcony 4 on the small building unit 61d, as shown in FIG. As shown in FIG. 3, the lower floor is vertically inserted into the positioning pin 65 projecting upward from the small building unit 61d (the upper end of the pillar 62 of the lower floor). The balcony 4 is suspended almost directly below the small building unit 61d. After being lowered onto the small building unit 61d on the lower floor, the space between the other side of the floor 21 and the small building unit 61d is appropriately fixed with bolts in the vertical direction.

On the other hand, on one side (porch portion 12) of the floor portion 21, the lower portion of the corner portion on the eaves side is fixed to the upper end portion of the balcony pillar 66 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 (one side of the floor portion 21) is inserted vertically into a positioning pin 65 (FIG. 13) projecting upward from the upper end portion of the balcony pillar 66. The balcony 4 is suspended almost directly below so that it can be seen. After hanging down onto the balcony pillar 66, bolts are vertically fixed between the corner portion on the eaves side (one side of the floor portion 21) and the balcony 4. - 特許庁

At this time, as shown in FIG. 13, the other side of the balcony 4 faces down so that the positioning pins 65 of the building unit 61d on the lower floor are fitted into the pin holes before the positioning pins 65 of the balcony pillars 66. It is preferable to keep it slightly tilted.

When the upper floor building units 61e to 61g are laminated and fixed on the lower floor building units 61a to 61c, as shown in FIG. A portion that interferes with the balcony 4 is appropriately cut out (notch portion 67).

Finally, the corner portion 27 on the side of the eaves (on one side of the floor portion 21) is fixed to (the building unit 61e of) the upper floor portion 3 of the building body 1. As shown in FIG. In this embodiment, the balcony 4 is arranged at the position of the upper floor portion 3 of the building body 1, and the three corner portions are fixed to portions other than the upper floor portion 3 of the building body 1.
