For example, in the case of a multi-story unit building 2, the building unit 3 on the lower floor is installed on the foundation, and the building unit 4 on the upper floor is installed on the building unit 3 on the lower floor. However, when the unit building 2 has three or more floors, the building unit 3 on the lower floor and the building unit 4 on the upper floor are relative. Normally, the building unit 3 on the lower floor and the building unit 4 on the upper floor have the same size and are stacked vertically while being aligned with each other. However, the building unit 3 on the lower floor and the building unit 4 on the upper floor may have different sizes stacked vertically, or stacked vertically with their positions shifted. . In the following embodiments, the building unit 3 on the lower floor and the building unit 4 on the upper floor are mainly made to have the same size and are vertically stacked in a mutually aligned state.

In this case, the floor surface 8 of the building unit 3 on the lower floor is installed around the foundation. At the boundary between the building unit 3 on the lower floor and the building unit 4 on the upper floor, the ceiling surface 9 of the building unit 3 on the lower floor and the floor surface 8 of the building unit 4 on the upper floor overlap vertically. installed in the state.

It has a third beam portion 13 that forms an internal corner portion 10 between itself and the first beam portion 11 by arranging so as to abut vertically on the intermediate portion in the longitudinal direction.

Here, the internal corner portion 10 is a recessed corner formed in a stepped portion of the adjacent building units 3a, 3b or 4a, 4b. The internal corner portion 10 is arranged according to the shape of the land. This may occur when the building units 3a, 3b or 4a, 4b are arranged adjacently (flying geese arrangement), or when the building units 3a, 3b or 4a, 4b are arranged adjacently with different directions. In FIG. 1A, by shifting the positions of the building units 3a, 3b and 4a, 4b in the unit building 2 in a direction 16 orthogonal to the adjacent direction 15, a total of two internal corners are shown in plan view. 10 has been formed. The two internal corner portions 10 are formed continuously over the upper and lower floors. 1B to 1D show an example in which a unit building 2 having an internal corner 10 is formed by, for example, a flying geese arrangement of building units 3 and 4, each of which has a total of four locations (FIG. 1B) when viewed in plan. Alternatively, two internal corner portions 10 (FIGS. 1C and 1D) are continuously provided over the upper and lower floors. The unit building 2 having the internal corner portion 10 may exist in various types other than those described above.

The first beam portion 11 and the second beam portion 12 are arranged substantially parallel to each other with at least one end position shifted with respect to the longitudinal direction.

The third beam portion 13 is the ceiling beam 6 or the floor beam 7 of the other building unit 3b, 4b located within the longitudinal range of the first beam portion 11. As shown in FIG.

In this embodiment, since the building units 3a, 3b or 4a, 4b of the same size are arranged adjacent to each other with their positions shifted in the direction 16 orthogonal to the adjacent direction 15, the inside corner 10 is located on the opposite side. It will be formed in two places. In the two internal corners 10, the first beam portion 11, the second beam portion 12 and the third beam portion 13 are reversed with respect to the adjacent building units 3a, 3b or 4a, 4b. have a relationship. Therefore, one building unit 3a, 4a and the other building unit 3b, 4b are relative, and the first beam 11, the second beam 12 and the third beam 13 are also relative. It is.

In this embodiment, one building unit 3a, 4a has a first beam 11, and the other building unit 3b, 4b has a second beam 12 and a third beam 13. However, the same applies to the case where the other building unit 3b, 4b has the first beam portion 11 and the one building unit 3a, 4a has the second beam portion 12 and the third beam portion 13. be. In addition, although not shown, by arranging building units 3a, 3b or 4a, 4b of different sizes adjacent to each other with the positions aligned on one side, the unit building 2 having one internal corner 10 on the opposite side can be obtained. can be formed.

As a result, as shown in FIG. 9, when the two building units 3a, 3b or 4a, 4b are adjacently arranged with the inside corner 10, the force F can be received by a substantially horizontal structural surface (at least one of the ceiling surface 9 and the floor surface 8) of the two building units 3a, 3b or 4a, 4b connected via the upper connection plate 21. become.

The ceiling surface 9 is defined by ceiling beams 6 assembled in a rectangular shape, and inside the rectangular ceiling beams 6, one or more horizontal beams are appropriately provided in the adjacent direction 15. Furthermore, the lower surface is provided with necessary and sufficient rigidity in the surface direction by attaching a ceiling surface material.

In addition, the floor surface 8 is defined by floor beams 7 assembled in a rectangular shape, and inside the rectangular floor beams 7, one or more horizontal beams are appropriately provided in the adjacent direction 15. Further, the upper surface is provided with necessary and sufficient rigidity in the surface direction by attaching a floor material.

Therefore, for example, as shown in the comparative examples of FIGS. 10 and 11, the corner portion of the internal corner portion 10 is positioned on the extension line of the third beam portion 13 inside one of the building units 3a and 4a. By providing an auxiliary beam 35 extending in the adjacent direction 15 from the inner corner 10, it is possible to eliminate the need for the auxiliary beam 35 to receive the force F in the adjacent direction 15 acting on the inside corner 10 in a line.

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

(Effect 7) A spacer 51 may be interposed between the second beam portion 12 and the lower floor ceiling beam 6 positioned below the second beam portion 12 . As a result, the ends or the vicinity of the ends of the floor beams 7 on the upper floor, which become the second beams 12 , are moved up and down by the ceiling beams 6 on the lower floor located below the second beams 12 via the spacers 51 . direction can be received.

The spacer 51 may have an extension 52 extending up to the ceiling beam 6 of the adjacent lower floor. As a result, the end portion or the vicinity of the end portion of the second beam portion 12 forming the internal corner portion 10 is vertically supported by the adjacent lower floor ceiling beam 6 via the extension portion 52 of the spacer 51. can be done. Therefore, the load of the end portion of the second beam portion 12 can be distributed and supported by the two ceiling beams 6 adjacent to each other in the two lower floor building units 3a and 3b' adjacent to each other. Therefore, it is possible to increase the support rigidity with respect to the second beam portion 12 of the upper floor and to suppress the deflection of each of the ceiling beams 6 of the lower floor.

(Effect 8) The spacer 51 may be made thicker than the distance d between the end or the vicinity of the end of the second beam portion 12 and the ceiling beam 6 of the lower floor located below. As a result, the end portion or the vicinity of the end portion of the second beam portion 12 can be reliably received from below by the ceiling beam 6 of the lower floor through the spacer 51 thicker than the above-described interval d. Moreover, even if there is an error from the design value (interval d) when actually installed, the end portion or the vicinity of the end portion of the second beam portion 12 can be supported without any trouble.

(Effect 9) The spacer 51 may be formed by laminating the elastic bodies 62 and 63 on the surface of the metal plate 61 . As a result, the metal plate 61 reliably supports the end portion of the second beam portion 12 , and the elastic bodies 62 and 63 support the end portion of the second beam portion 12 , near the end portion, or below the spacer 51 . It is possible to soften the contact with the ceiling beams 6 on the lower floor located in the lower floor, prevent the spacers 51 from being displaced, and prevent the spacers 51 from transmitting vibration and generating noise.

(Effect 10) By setting back the building unit 4b on the upper floor with respect to the building unit 3b' on the lower floor, the inside corner 10 may be formed only on the upper floor. In this case, the positions of the pillars 5 of the building unit 3b' on the lower floor and the building unit 4b on the upper floor forming the inside corner 10 do not match. For example, as shown in FIG. It becomes necessary to provide a center post 65 at the position or additionally install a reinforcing beam 66 or the like along the bottom of the second beam portion 12 .

On the other hand, the end portion or the vicinity of the end portion of the second beam portion 12 is connected via the spacer 51 and the extension portion 52 to the ceiling beam 6 of the lower floor located below the second beam portion 12 and the adjacent lower floor. The central pillar 65, the reinforcing beam 66, etc. can be made unnecessary by receiving the ceiling beam 6. - 特許庁Therefore, the structure having the internal corners 10 only on the upper floors in the vertical direction can be realized at a low cost. It is possible to improve the degree of freedom in planning.
