In the following, among the outer wall portions 70 forming the outer shells on all four sides, the one forming the outer shell on the east side is the "eastern outer wall portion 71", the one forming the outer shell on the west side is the "western outer wall portion 72", and the outer shell on the south side is formed. May be referred to as "south side outer wall portion 73", and those forming the outer hull on the north side may be referred to as "north side outer wall portion 74".

As shown in FIG. 2, the east side outer wall portion 71 is provided with the wall thickness direction facing the east-west direction. Similar to the east side outer wall portion 71, the west side outer wall portion 72 is provided so as to face the wall thickness direction in the east-west direction and to be separated from the east side outer wall portion 71 to the west. The south outer wall portion 73 is provided so as to face the wall thickness direction in the north-south direction and to connect the south end of the east side outer wall portion 71 and the west side outer wall portion 72 to each other. The north outer wall portion 74 is provided so that the wall thickness direction is directed in the north-south direction as in the south outer wall portion 73, and the north ends of the east side outer wall portion 71 and the west side outer wall portion 72 are connected to each other.

In this way, the house 1 is formed as a building with the wall surfaces facing in all directions. The indoor space of the house 1 is divided into a first floor and a second floor by a ceiling portion 6 (see FIG. 6). Various rooms and facilities are provided on the first and second floors of the house 1.

Next, the configuration of the first floor of the house 1 will be described with reference to FIG.

As shown in FIG. 2, on the first floor of the house 1, the entrance porch 10, the entrance 11, the corridor 12, the Japanese-style room 13, the stairs 14, the toilet 15, the washroom 16, the bathroom 17, the living room 18, the dining room 19, the kitchen 20, etc. Is formed.

The entrance porch 10 is formed in the southwestern part of the first floor. The entrance 11 is formed on the north side of the entrance porch 10. The entrance door 31 is provided at the entrance 11. On the north side of the entrance 11, a corridor 12 extending to the north side through the corridor door 32 is formed. A Japanese-style room 13 is formed at the end of the north side of the corridor 12. Further, the northern part of the corridor 12 is connected to the living room 18 where the television 37 and the like are provided. The living room 18 is formed on the south side of the center of the first floor. On the north side of the living room 18, a staircase 14 leading to the second floor is formed. Below the stairs 14, a storage 33 under the stairs of the Japanese-style room 13 is formed. Further, a toilet 15 and a washroom 16 are formed on the north side of the living room 18 and on the east side of the stairs 14. A bathroom 17 is formed on the east side of the washroom 16.

A dining room 19 is formed on the east side of the living room 18. Dining 19 is formed in the southeastern part of the first floor. In this way, the living room 18 and the dining room 19 are formed so as to face the south outer wall portion 73. A kitchen 20 is formed on the north side of the dining 19. In this way, the dining 19 and the kitchen 20 are formed so as to face the east side outer wall portion 71. In this way, the living room 18, the dining room 19 and the kitchen 20 are made easy to take in sunlight through the plurality of windows 78 formed in the south side outer wall portion 73 and the east side outer wall portion 71.

The pillar 81 is not provided in the indoor space on the first floor. That is, the indoor space on the first floor is formed as a pillar-free space. In this way, the living room 18, the dining room 19, and the kitchen 20 are connected to each other without the pillar 81, and thus are formed as one large space full of openness.

Here, FIGS. 24 and 25 show an example of the configuration of the first floor of a general house (hereinafter referred to as "general house 901") (different from the house 1 according to the present embodiment) in the present embodiment. It is illustrated so as to correspond to the structure of the house 1 (similarly provided rooms and facilities are designated by the same reference numerals).

As shown in FIGS. 24 and 25, a pillar 981 is provided in the internal space on the first floor of the general house 901. The pillar 981 is a portion on the north side of the living room 18, and is provided on the west side of the kitchen 20 (that is, substantially the center in a plan view of the general house 901). The pillar 981 is erected from a reserve foundation 950 provided so as to cross the inside of the foundation body 50 of the foundation 2. The column 981 supports the beam 982a and the beam 982b together with another column 81 connected to the foundation body 50 of the foundation 2. The beams 982a and 982b are provided so as to cross the ceiling portion 6 on the first floor in the east-west direction. As described above, in the general house 901, the pillar 981 is provided in the internal space of the first floor in order to support the beams 982a and 982b that receive the load on the second floor and the ceiling.

On the other hand, in the house 1 according to the present embodiment, the interior space on the first floor is formed as a pillar-free space having no pillars such as pillars 981, unlike the general house 901 as described above. Such a column-free space is realized by a configuration including the girder 113, an outer column 111, an inner column 112, and a protruding foundation 60 (hereinafter, referred to as “erection configuration 100”).

In the present embodiment, as shown in FIG. 2, the house 1 is provided with two erection configurations 100 so as to be arranged in the east-west direction. Here, the east side erection configuration 100 and the west side erection configuration 100 are substantially the same in other configurations except that the arrangement locations are different from each other. Therefore, in the following, the east side erection configuration 100 will be mainly described, and the west side erection configuration 100 will be omitted as appropriate. Therefore, in the following description, unless otherwise specified, the "erection configuration 100" refers to the erection configuration 100 on the east side.

Hereinafter, the erection configuration 100 according to the first embodiment will be described in detail with reference to FIGS. 2 to 8.

As described above, the erection configuration 100 is a configuration for forming the interior space of the first floor of the house 1 as a pillar-free space. As shown in FIG. 4, the erection configuration 100 includes a protruding foundation 60 included in the foundation 2, outer columns 111 and inner columns 112 included in the plurality of columns 81, and girders 113 included in the plurality of beams 82. Is included.

The erection configuration 100 is substantially the same as the other configurations except that the configuration on the south side and the configuration on the north side are symmetrical with each other in the north-south direction. Therefore, in the following, the configuration on the south side of the erection configuration 100 will be mainly described, and the description on the configuration on the north side will be omitted as appropriate.

The protruding foundation 60 shown in FIGS. 3 to 5 is a peninsula-shaped portion of the foundation 2 that projects outward from the foundation body 50. Specifically, the projecting foundation 60 projects to the south side (outside) from a portion of the foundation body 50 that extends in the east-west direction on the south side. In FIG. 5, in order to clarify the portion of the foundation 2 corresponding to the protruding foundation 60, a diagonal line is drawn in the portion. As shown in FIG. 5A, the protruding foundation 60 has a base portion 61 and a rising portion 62.

The base portion 61 is provided on the south side (outside) of the base portion 51 of the foundation 2 (foundation main body 50). The base portion 61 is connected to the base portion 51. The base portion 61 is provided so as to extend in the east-west direction (specifically, to be longer in a plan view than the rising portion 62 described later). The upper surface of the base portion 61 is provided so as to be continuous with the upper surface of the base portion 51.

The rising portion 62 is provided on the south side (outside) of the rising portion 52 of the foundation 2 (foundation main body 50). The rising portion 62 is provided so as to rise upward from the base portion 61 and the base portion 51. The rising portion 62 is connected to the base portion 61 and the base portion 51. The south side (outside) end of the rising portion 62 is located at the same position as the south side (outside) end of the base portion 61 in a plan view.

The configuration of the protruding foundation 60 is not limited to the configuration as described above. For example, as shown in FIG. 5B, if the width (length in the indoor / outdoor direction) of the base portion 51 of the foundation 2 is long (specifically, the rising portion of the protruding foundation 60 in a plan view). If the outer end of the 62 is located inside the outer end of the base 51), the base 61 may not be provided.

The outer columns 111 and inner columns 112 shown in FIGS. 2 to 7 are columns that support the girder 113 described later. The outer column 111 and the inner column 112 are formed in a longitudinal shape by a square steel pipe. The outer pillar 111 and the inner pillar 112 are formed so as to extend linearly in the vertical direction. In this way, the outer pillar 111 and the inner pillar 112 are formed so as to be parallel to each other from the upper end to the lower end, respectively. The outer pillar 111 and the inner pillar 112 are provided so as to be separated from each other in the indoor and outdoor directions. The distance between the outer pillar 111 and the inner pillar 112 is set, for example, from 20 cm to 100 cm.

As shown in FIG. 5A, the lower end of the outer pillar 111 is connected to the protruding foundation 60 (rising portion 62) of the foundation 2 via a predetermined metal fitting. In this way, the outer pillar 111 is provided so as to extend above the protruding foundation 60 in the vertical direction. As shown in FIGS. 2 and 6, the inner (north side) end of the outer pillar 111 is located on the outer side (south side) of the line of the south side outer wall portion 73. More specifically, the "south side outer wall portion 73" refers to a portion of the south side outer wall portion 73 located immediately east and west of the outer pillar 111 in the east-west direction, that is, a portion in the vicinity of the outer pillar 111. It is a thing. Further, the "line" refers to the outer edge of the exterior surface material constituting the outer wall portion 70 in a plan view (or a side view) (see reference numeral L shown in FIGS. 2 and 6).

In this way, since the inner end of the outer pillar 111 is located outside the line of the south outer wall portion 73, the outer pillar 111 can be provided as a structure different from the south side outer wall portion 73 which is the conventional configuration. .. That is, since it is possible to save the trouble of newly redesigning the south side outer wall portion 73, which is the conventional configuration, for the outer pillar 111, the workability can be improved.

As shown in FIG. 5A, the lower end of the inner pillar 112 is connected to the foundation main body 50 (rising portion 52) of the foundation 2 via a predetermined metal fitting. In this way, the inner pillar 112 is provided so as to extend above the foundation main body 50 in the vertical direction, like the other pillars 81 constituting the outer wall portion 70. The outer (south side) end of the inner pillar 112 is located inside (north side) of the line of the south side outer wall portion 73.

In this way, since the outer end of the inner pillar 112 is located inside the line of the south outer wall portion 73, the inner pillar 112 has the same configuration as the pillar 81 included in the south side outer wall portion 73, which is a conventional configuration. As a result, the pillar 81 can be used as a pillar constituting the erection configuration 100. In this way, workability can be improved.

The girder 113 shown in FIGS. 3, 4 and 6 is a single H-shaped steel which is a longitudinal member. The girder 113 is provided with its longitudinal direction facing north-south. The girder 113 is provided so as to cross between the south side outer wall portion 73 and the north side outer wall portion 74. More specifically, the girder 113 is provided so as to extend from the immediate side of the window 78 formed on the south outer wall portion 73 facing the living room 18 to the portion between the Japanese-style room 13 and the stairs 14 in a plan view. (See FIGS. 2 and 3). The length of the girder 113 in the longitudinal direction is formed longer than the length between the south outer wall portion 73 and the north outer wall portion 74 (for example, 7 m in this embodiment).

The girder 113 is provided above the outer column 111 and the inner column 112. Specifically, the outer end portion of the girder 113 (including the outer end, for example, a portion from the outer end to the inner side of about 1 m) is provided above the outer column 111 and the inner column 112. The outer end of the girder 113 is located at the same position as the outer end of the outer column 111 in the indoor and outdoor directions. That is, the outer end of the girder 113 is located on the outer side (south side) of the line of the southern outer wall portion 73. As shown in FIG. 7A, the girder 113 is connected to the outer column 111 and the inner column 112 via a predetermined metal fitting provided below.

The configuration of the connection between the girder 113 and the outer column 111 and the inner column 112 is not limited to the configuration as described above. For example, as shown in FIG. 7B, the girder 113 may be connected to the outer pillar 111 via a predetermined metal fitting 113a provided outside the outer end of the girder 113. In such a case, the length of the girder 113 is shortened by the width of the metal fitting 113a (the length in the indoor / outdoor direction).

The configuration of the girder 113 is not limited to the configuration as described above. For example, instead of the one H-shaped steel in advance, an H-shaped steel obtained by connecting a plurality of (for example, two) H-shaped steels to form one may be used as the girder 113. In this case, as a method of connecting the two H-shaped steels, friction stir welding using high-strength bolts can be adopted. Specifically, as shown in FIGS. 8A and 8B, two H-beams subjected to friction surface treatment are arranged so as to abut each other. Then, two H-shaped steels abutted can be rigidly joined by using a plurality of plate-shaped members 92 and high-strength bolts 93 that have been subjected to friction surface treatment.

In this way, for example, even if a truck that transports materials to a construction site cannot load a girder 113 of the required length due to a problem such as a loadable length, two H-shaped steels are connected at the construction site. By doing so, one girder 113 of the required length can be arranged. The method of connecting the two H-shaped steels is not limited to the friction stir welding as described above, and for example, welding or the like can be adopted.

Further, although the configuration on the south side of the erection configuration 100 has been described as described above, the configuration on the north side is also substantially the same.

In this way, in the erection configuration 100, the girder 113 is supported by two columns (outer column 111 and inner column 112) that are separated from each other at both ends (south end and north end) in the longitudinal direction. , Constructed as a continuous beam. That is, since the girder 113 has many fulcrums as compared with the case where it is configured as a simple beam, for example, the stress at the central portion in the longitudinal direction can be reduced. As a result, the house 1 having the erection configuration 100 does not need to be provided with columns (for example, columns 981 shown in FIGS. 24 and 25) for supporting the girder 113 at the central portion in the longitudinal direction, and is an internal space on the first floor. The interior can be formed as a pillar-free space with a feeling of openness.

Here, in the case where the erection configuration 100 according to the present embodiment is not adopted and the interior space of the first floor is formed as a pillarless space, the stress on the central portion of the girder 113 in the longitudinal direction is countered. Therefore, a method of increasing the beam stress of the girder 113 (for example, a method of joining two H-shaped steels in two upper and lower stages) is assumed.

However, when the method of stacking two H-shaped steels in two upper and lower layers to form a girder 113 is adopted, the beam height becomes large, so that the ceiling height becomes low or a part of the girder 113 is partially ceilinged. There is a risk of being exposed downward (living space) from the bottom surface of the. Further, since H-shaped steel having two upper and lower stages is used, the amount of steel material may increase and the cost may increase. Further, since the upper and lower two-stage H-shaped steels are integrated, the amount of welding increases, welding strain may occur, and the girder 113 may warp (that is, the quality may deteriorate). In addition, when remodeling is performed in the future, the degree of freedom in design (future variability of a large space) may decrease because the beam is large. In addition, since the upper and lower two-tiered H-beams cannot be divided in the middle, they may not be used for buildings built in narrow areas.

On the other hand, in the erection configuration 100 according to the present embodiment, one H-shaped steel, which is a member of a general steel frame beam, is used as the girder 113. Therefore, since the beam sill does not increase (compared to a general standard), there is no possibility that the ceiling height becomes low or a part of the girder 113 is exposed downward (living space) from the lower surface of the ceiling. Similarly, since the amount of steel material does not increase, there is no possibility that the cost will increase. Similarly, since the amount of welding does not increase, welding strain is unlikely to occur, and the girder 113 is less likely to warp. In addition, there is no risk that the degree of freedom in design (future variability of a large space) will decrease when remodeling is performed in the future. Further, since the girder 113 can be divided in the middle, it can be adopted even in a building built in a narrow area.

As described above, the outer pillar 111 is located on the outer side (south side) of the line of the southern outer wall portion 73. In the house 1 according to the present embodiment, as shown in FIGS. 1 to 3 and 6, the sleeve wall 75 is provided by utilizing the outer pillar 111. The sleeve wall 75 is formed so as to project outward from the outer wall portion 70. Specifically, in the north side outer wall portion 74, two sleeve walls 75 are provided so as to extend in the vertical direction between the ground and the roof 4 outside the line of the north side outer wall portion 74. Further, in the south side outer wall portion 73, two sleeve walls 75 are provided so as to extend in the vertical direction between the ground and the balcony 5 outside the line of the south side outer wall portion 73.

With such a configuration, the design of the house 1 can be improved by forming the sleeve wall 75 on the outer wall portion 70, which is generally not provided with a characteristic structure.

As described above, in the house 1 according to the embodiment of the present invention,
A girder 113 erected between a pair of outer wall portions (south side outer wall portion 73 and north side outer wall portion 74) that divide the indoor and outdoor parts of a house 1 (building), and
A pair of column portions (outer column 111 and inner column 112 on the south side, outer column 111 and inner column 112 on the north side) provided at both ends of the girder 113 in the longitudinal direction.
Equipped with
At least one of the pair of pillars
It has two columns (outer column 111 and inner column 112) that are provided apart from each other in the longitudinal direction of the beam and each support the girder 113.

With such a configuration, it is possible to eliminate the need to provide columns in the indoor space while receiving the load of the upper floor and the ceiling by the girder 113. In this way, in the house 1, the indoor space on the first floor can be formed as a pillar-free space, and by extension, it can be formed as one large space full of openness.

Also, in house 1,
The two pillars (outer pillar 111 and inner pillar 112) are
Each is joined to the foundation 2 (foundation or foundation) of the house 1.

With such a configuration, the end portion of the girder 113 can be stably supported.

Also, in house 1,
The outer pillar 111 (at least one of the two pillars) is
It is provided outside the line L on the outer surface of the outer wall portion 70.

With such a configuration, it is possible to improve the workability because it is possible to save the trouble of redesigning the outer wall portion 70, which is the conventional configuration, for the outer pillar 111.

In addition, in house 1,
A sleeve wall 75 projecting outward from the outer wall portion 70 is provided.
The outer pillar 111 (at least one of the two pillars) is
It constitutes the sleeve wall 75.

With such a configuration, the design of the house 1 can be improved.

Also, in house 1,
The inner pillar 112 (at least the other of the two pillars) is
It is provided inside the line L on the outer surface of the outer wall portion 70.

With such a configuration, the pillar 81 included in the outer wall portion 70, which is a conventional configuration, can be used as a pillar constituting the erection configuration 100. In this way, workability can be improved.

The south side outer wall portion 73 and the north side outer wall portion 74 according to the present embodiment are one embodiment of the pair of outer wall portions.
