In such a mixed structure, the wooden parts also bear the horizontal load, so it is necessary to increase the cross-sectional shape of the columns and beams of the wooden parts. When the cross-sectional shapes of columns and beams become large, it becomes difficult to realize large spaces and high ceiling heights.
In addition, it is necessary to strengthen the column-beam joints, which increases construction time and costs. Another problem is that the number of structural engineers who can handle this is limited because the design and structural calculations of the column-beam joints become complicated because the wooden parts bear horizontal loads.

Therefore, an object of the present invention is to provide a building structure that can realize a structure in which the wooden parts do not bear horizontal loads.

That is, the cross-sectional shapes of the wooden beams on each floor can be made uniform without increasing the cross-sectional shapes of the wooden beams on the upper floors.
Since wooden beams with the same cross-sectional shape can be installed on all floors, construction management is easier compared to installing wooden beams with different cross-sectional shapes on each floor. , the design can be improved.

Moreover, in the connecting column unit according to the present invention, the wooden column provided on the first floor and the wooden column provided on the second floor or higher may have the same cross-sectional shape.

In the present invention, since the wooden columns have a structure that only bears vertical loads, the cross-sectional shape of the wooden columns on each floor can be made smaller compared to the case where they also bear horizontal loads. In conventional building structures, the cross-sectional dimensions of the wooden pillars on the lower floors are larger than those on the upper floors, but in the present invention, the cross-sectional shape of the wooden pillars on the first floor can be made smaller, and other purposes and effects can be achieved. As a priority, the cross-sectional shape of the wooden columns provided on the second floor and above can be made to be the same as the cross-sectional shape of the first floor.
For example, by providing wooden columns with the same cross-sectional shape on every floor, construction management becomes easier compared to installing wooden columns with different cross-sectional shapes on each floor, and in the case of a design in which the wooden columns are exposed, , the design can be improved. Further, according to the present invention, by forming wooden beams with the same cross-sectional shape and then using wooden columns with the same cross-sectional shape, the overall design including the wooden beam and the wooden pillar can be improved.

Therefore, an object of the present invention is to provide a building structure that can realize a structure in which the wooden parts do not bear horizontal loads.

Next, the functions and effects of the building structure according to the embodiment of the present invention described above will be explained using the drawings.
In the building structure according to the embodiment of the present invention, the wooden columns 5 are pin-connected to the outer peripheral beams 7 that can transmit horizontal loads to the core part 3, and the wooden columns 5 and the wooden beams 6 do not transmit moments to each other. This is one of the configurations in which no moment is expected to be transferred to each other. Thereby, the wooden pillars 5 and the wooden beams 6 of the wooden part 2 can be configured to bear only the vertical load without bearing the horizontal load. Therefore, the cross-sectional size of the wooden columns 5 and wooden beams 6 of the wooden part 2 can be suppressed. As a result, the floor area of the building 1 does not become smaller due to an increase in the cross-sectional shape of the wooden columns 5, and the ceiling height does not become smaller due to an increase in the cross-sectional area of the wooden beams 6. In other words, it becomes possible to realize a large space and a high ceiling height. Further, since there is no need to strengthen the column-beam joint between the wooden columns 5 and the wooden beams 6, the construction period and cost are not increased. Furthermore, since the wooden part 2 does not bear a horizontal load, the design and structural calculation of the column-beam joint becomes simple, and many structural engineers can easily design it.

In the building structure according to the embodiment of the present invention, the horizontal load that originally acts on the wooden columns 5 can be efficiently transmitted to the core section 3 by a simple structure in which the wooden columns 5 of the wooden section 2 are pin-connected to the outer peripheral beam 7. Can be done.

In the building structure according to the embodiment of the invention, the floor slab 81 is joined to the wooden beam 6.
Therefore, the horizontal load that originally acts on the wooden part 2 can be efficiently transmitted from the floor part 8 to the core part 3.

In the building structure according to the embodiment of the present invention, the core part 3 is a steel structure. With such a configuration, the structural performance of the core portion 3 is stabilized, and the horizontal load acting on the building 1 can be efficiently borne. It is possible to shorten the construction period for constructing the core part 3 and to secure a wide space inside the core part 3.

In the building structure according to the embodiment of the present invention, the cross-sectional shape of the wooden beam 6 provided on the third floor of the building 1 is the same as the cross-sectional shape of the wooden beam 6 provided on the first and second floors.
In conventional building structures, the cross-sectional dimensions of wooden beams are larger on lower floors than on upper floors. In this embodiment, since the wooden part 2 has a structure that does not bear horizontal loads, the cross-sectional shape of the wooden beam 6 on each floor can be made small. Thereby, when aligning the cross-sectional shapes of the wooden beams 6 on each floor, the cross-sectional shape of the wooden beams 6 on the lower floor can be made smaller to have the same cross-sectional shape as the wooden beams 6 on the upper floor. That is, the cross-sectional shapes of the wooden beams 6 on each floor can be made uniform without increasing the cross-sectional shapes of the wooden beams 6 on the upper floors.
Since wooden beams 6 with the same cross-sectional shape can be provided on all floors, construction management is easier compared to the case where wooden beams 6 with different cross-sectional shapes are provided on each floor, and the design allows the wooden beams 6 to be exposed. In this case, the design quality can be improved.

In the building structure according to the embodiment of the present invention, the cross-sectional shape of the wooden pillar 5 provided on the first floor of the building 1 is the same as the cross-sectional shape of the wooden pillar 5 provided on the second and third floors.
In this embodiment, since the wooden columns 5 have a structure that bears only vertical loads, the cross-sectional shape of the wooden columns 5 on each floor can be made smaller compared to the case where they also bear horizontal loads. In conventional building structures, the cross-sectional dimensions of the wooden columns 5 on the lower floors are larger than those on the upper floors, but in this embodiment, the cross-sectional dimensions of the wooden columns 5 on the first floor can be made smaller, so that other purposes can be achieved. - Prioritizing the effect, the cross-sectional shape of the wooden columns 5 provided on the second floor and above can be made the same as the cross-sectional shape of the first floor.
For example, by providing wooden columns 5 with the same cross-sectional shape on all floors, construction management becomes easier compared to the case where wooden columns 5 with different cross-sectional shapes are provided on each floor, and the design allows the wooden columns 5 to be exposed. In this case, the design quality can be improved. Further, according to the present embodiment, by using the wooden beams 6 with the same cross-sectional shape and the wooden columns 5 with the same cross-sectional shape, the overall design including the wooden beams 6 and the wooden columns 5 can be improved.
