In the buildings described in Patent Documents 1 and 2, in the space below the slab directly above the ceiling space, etc., although the equipment pipes can be freely installed along the second direction through the second direction equipment pipe space, In order to arrange the facility piping along the , an insertion hole for inserting the facility piping must be formed through the second direction beam extending along the second direction afterwards. However, since there are restrictions on the number and positions of insertion holes that can be formed in the second direction beam, equipment piping cannot be freely installed along the second direction. As a result, there is a problem that the degree of freedom in setting the facility piping route is low.
In view of this situation, a main object of the present invention is to provide a building with a high degree of freedom in setting facility piping routes in which facility piping can be freely installed along the first direction and the second direction.

In a first characteristic configuration of the present invention, at least a pair of first frame portions and a second frame portion disposed between the pair of first frame portions are arranged in a first direction in plan view. a building that is
A column span in a second direction that intersects the first direction in plan view is configured to be smaller than a column span in the first direction,
In the second frame portion, the intermediate portion in the beam length direction of the first direction beam extending in the first direction is omitted, and the intermediate portion in the beam length direction of the first direction beam is aligned along the second direction. A second direction equipment piping space in which equipment piping can be arranged is formed,
A second direction beam extending in the second direction is eliminated at the boundary between the pair of first frame portions and the second frame portion, and the area where the second direction beams are eliminated is provided along the first direction. A first direction facility piping space is formed in which piping can be arranged ,
The external pillars arranged on the exterior side of the building in a state of being aligned in the second direction are configured as second direction flat pillars that are flat in the second direction,
The point is that the internal pillars arranged on the inside side of the building are configured as first direction flat pillars that are flat in the first direction .

According to this configuration, since both the first direction facility piping space and the second direction facility piping space are formed, the facility piping can be freely installed along the first direction and the second direction, The building can have a high degree of freedom in setting facility piping routes.
Moreover, the first-direction equipment piping space is formed by eliminating the second-direction beam in the second direction where the column span (column interval) is small and the impact on bearing strength due to elimination of the beam is small. The directional facility piping space is the first direction on the side where the column span (column interval) is large and the impact on the bearing strength due to the elimination of the beam is large. The beam is formed leaving at least both ends in the beam length direction. Therefore, the first direction facility piping space and the second direction facility piping space can be formed while ensuring the expected strength of the building, and a building with a high degree of freedom in setting the facility piping route can be rationally constructed. can.

Furthermore, according to this configuration, in the second direction on the small column span side, the second direction beams are eliminated in the external columns arranged in the second direction, which are configured as second direction flat columns that are flat in the second direction. It is possible to appropriately bear the horizontal force for the amount of the load. On the other hand, in the first direction on the large column span side, the internal column configured as a first direction flat column that is flat in the first direction has a horizontal force corresponding to the amount of the beam length direction intermediate part of the first direction beam that is omitted. can be borne appropriately. Therefore, it is possible to more rationally construct a building with a high degree of freedom in setting facility piping routes.

A second characteristic configuration of the present invention resides in that a living room is formed in the pair of first frame portions, and a corridor is formed in the second frame portion.

According to this configuration, it is possible to construct a middle corridor type building in which living rooms are configured on both sides of the corridor in the first direction. Then, equipment piping (for example, equipment piping common to each living room) is installed in the corridor along the second direction, and equipment piping (for example, living room By installing individual equipment piping for each building, it is possible to set equipment piping routes that are particularly suitable for buildings with central corridors.

FIG. 5 shows the floor plan of the building B of the present invention, showing partition walls 50, glass windows 60, etc. in addition to the pillars 10. As shown in FIG.

As shown in FIG. 1, the building B uses a frame structure having a plurality of pillars 10 and a plurality of large beams 20 provided between the pillars 10 . As shown in FIGS. 3 and 4, a slab 30 is provided on the upper part of the frame structure of each floor of the building B. As shown in FIGS. In addition, the frame structure of each floor is appropriately provided with load-bearing walls 40 (see FIG. 1) and the like for resisting horizontal force. In this embodiment, the columns 10, the large beams 20, the slabs 30, the load-bearing walls 40, etc. are made of reinforced concrete.

In addition, in the building B, at least a pair of first frame portions K1 and a second frame portion K2 arranged between the pair of first frame portions K1 are arranged in the X direction (left and right in FIG. 2) in a plan view. direction (corresponding to the first direction). The pair of first frame sections K1 are arranged separately on both ends of the building B in the X direction, and the second frame section K2 is arranged on the center side of the building B in the X direction. The first frame portion K1 and the second frame portion K2 are provided over the entire length of the Y direction (corresponding to the vertical direction in FIG. 2, which corresponds to the second direction) orthogonal to the X direction (an example of crossing) in plan view. ing. In this building B, the column span (column interval) in the Y direction is smaller than the column span (column interval) in the X direction.

As shown in FIGS. 2 to 4, the first frame portion K1 includes a plurality of external pillars 11 arranged on the exterior side of the building in a state of being aligned in the Y direction, and a large beam 20 extending between the external pillars 11 adjacent in the Y direction. Y-direction beams (corresponding to second-direction beams) 21Y as , internal pillars 12 adjacent to the external pillars 11 in the X direction and arranged inside the building, and the external pillars 11 and the internal pillars 12 and a first X-direction beam (an example of a first-direction beam) 22X as the girders 20 extending across.

Then, at the boundary between the pair of first frame portion K1 and the second frame portion K2, the Y-direction beams between the inner columns 12 adjacent in the Y-direction are eliminated, and the Y-direction beams are eliminated in the region S2 in the X-direction. An X-direction equipment pipe space (corresponding to a first-direction pipe space) SX is formed along which the equipment pipe H can be arranged.
Therefore, in the space below the slab 30 such as the ceiling space, the equipment piping H (see FIG. 4) can be installed along the X direction through the X-direction equipment piping space SX, and the equipment piping route R extending in the X direction can be installed. (see FIG. 2) can be set.

As shown in FIGS. 2 and 3, the second frame portion K2 includes a pair of internal columns 12 adjacent in the X direction, and a second X-direction column disposed between the pair of internal columns 12 and extending in the X direction. beams 23X.
In the second frame portion K2, the beam length direction intermediate portion of the second X-direction beam 23X is omitted, and the beam length direction intermediate portion of the second X-direction beam 23X is omitted in the region S1 in the Y direction. A Y-direction facility piping space (second-direction facility piping space) SY along which the facility piping H can be arranged is formed. The second X-direction beams 23X are composed of a pair of projecting beams 23a projecting toward the inside of the building along the X direction from each of the pair of internal pillars 12, and are configured as a beam structure without intermediate portions in the beam length direction. there is
Therefore, in the space below the slab 30 such as the ceiling space, the equipment pipe H (see FIG. 3) can be installed along the Y direction through the Y-direction equipment pipe space SY, and the equipment pipe route R extending in the Y direction (see FIG. 2) can be set.

In this way, both the X-direction facility piping space SX and the Y-direction facility piping space SY are formed in the space below the slab 30, so that the facility piping H can be freely installed along the X and Y directions. , and the building B can have a high degree of freedom in setting the facility piping route R.

Moreover, the X-direction facility piping space SX is formed by eliminating the Y-direction beam in the Y direction, which has a small column span and is less affected by eliminating the large beam 20, and on the other hand, the Y-direction facility piping space SY is formed. , the middle part in the beam length direction of the second X-direction beam 23X is omitted in the X direction on the side where the column span is large and the influence on the bearing strength by eliminating the large beam 20 is large, and at least in the beam length direction of the X-direction beam 23X Both ends are formed.
Therefore, both the facility piping spaces SX and SY can be formed while ensuring the desired bearing strength in the building B, and the building B with a high degree of freedom in setting the facility piping route R can be rationally constructed.

Furthermore, in this building B, the external pillars 11 arranged on the exterior side of the building in a state of being aligned in the Y direction are configured as Y-direction flat pillars (corresponding to second-direction flat pillars) that are flat in the second direction. . For example, the cross-sectional shape of the external column 11 is formed in a rectangular shape elongated in the Y direction, with the long sides arranged in the Y direction and the short sides arranged in the X direction.

In addition, the internal pillars 12 arranged inside the building are configured as X-direction flat pillars (corresponding to first-direction flat pillars) that are flat in the X direction. For example, the cross-sectional shape of the internal column 12 is formed in a rectangular shape elongated in the X direction, with the long sides arranged in the X direction and the short sides arranged in the Y direction.

Therefore, in the Y direction where the column span is small, the external column 11 configured as the Y direction flat column can appropriately bear the horizontal force corresponding to the elimination of the Y direction beam. On the other hand, in the X direction where the column span is large, the internal column 12 configured as the X direction flat column appropriately bears the horizontal force corresponding to the omission of the beam length direction intermediate portion of the second X direction beam 23X. can do.

In this building B, as shown in FIG. 1, load-bearing walls 40 can be provided along the X direction so as to bear the horizontal force in the X direction on the side with the larger column span. In addition, the Y-direction beam 21Y can be configured as a wall garter with a beam width smaller than usual and a beam height larger than usual so as to bear the horizontal force in the Y direction on the side with the smaller column span. .

It can be suitably configured as a central corridor type building B.
In this case, for example, a living room is formed by a pair of first frame parts K1, and a corridor is formed by the second frame part K2. In the example shown in FIG. 5, a living room is defined in a region including the entire first frame K1 and the X-direction end of the second frame K2, and the X-direction intermediate portion of the second frame K2 (Y-direction equipment piping) A corridor is formed at the formation location of the space SY (see FIG. 1).
