FIG. 2 is a cross-sectional view of the building 1 along the line II-II of FIG. FIG. 3 is a cross-sectional view of the building 1 along the line III-III of FIG.

Building 1 is, for example, a multi-story apartment building. The building 1 mainly includes a skeleton structure 2 that serves as a skeleton, and a plurality of infill assemblies 3 that are detachably provided to the skeleton structure 2.

The skeleton structure 2 is a structure in which a plurality of beams 21 and a plurality of columns 22 are assembled so as to intersect each other. That is, the shape of the skeleton structure 2 is a cube or a rectangular parallelepiped shape, and the skeleton structure 2 has four outer surfaces 20. The lowermost beam 21 is arranged above the ground G, and a piloti space 4 communicating with the outdoor space is formed on the ground floor. The skeleton structure 2 is supported by a plurality of decorative columns 41. The decorative pillar 41 may be provided integrally with the pillar 22.

The infill assembly 3 is a box body that forms a living space 30 inside. The living space 30 includes a living room space such as a living room where residents regularly spend time and a non-living room space such as a sanitary room. The building 1 does not have to be a residential building such as an office building or an accommodation facility. In this case, the living space 30 may include at least a space where the user regularly spends time.

The box body as the infill assembly 3 can accommodate interiors, equipment, and the like inside, and can be transported in the accommodated state. As equipment, it is desirable that the equipment unit in which wiring, piping, etc. are unitized is housed in a box. It is desirable that the beams 21 and columns 22 constituting the skeleton structure 2 have built-in wiring, piping, and the like connected to the equipment in the infill assembly 3.

In the present embodiment, as shown in FIG. 2, four infill assemblies 3 having substantially the same size are arranged so as to intersect each floor in a swastika shape. That is, the infill assembly 3 has a substantially rectangular parallelepiped shape, one end face in the longitudinal direction of the infill assembly 3 is exposed from the skeleton structure 2, and the other end face in the longitudinal direction is adjacent to the side wall surface of the other infill assembly 3. As a result, a stairwell space 5 in which the infill assembly 3 does not exist is formed in the central portion of the skeleton structure 2. The atrium space 5 communicates with the piloti space 4.

It is assumed that one side of the infill assembly 3 in the longitudinal direction is the front side (front side) of the infill assembly 3, and the other side in the longitudinal direction is the rear side (back side) of the infill assembly 3.

In the building 1 of the present embodiment, as shown in FIG. 2, the infill assembly 3 has a plurality of tubular infill units 31 fixed to the skeleton structure 2 and a skeleton structure connected to each infill unit 31. A cap body 32 protruding from the body 2 to the outdoor side is provided. The cap body 32 closes the front open end of the infill unit 31.

The atrium space 5 constitutes a movement route for residents, and an elevator and stairs are provided in the atrium space 5. Alternatively, as shown in FIG. 3, a lift 50 for a car is provided in the atrium space 5, and the car is raised and lowered by the lift 50, so that the piloti space 4 and the living space 30 in the infill assembly 3 are separated from each other. It may be possible to move. Further, in this case, the same number of cars as the number of dwelling units (for example, the number of infill assemblies 3) may be parked in the piloti space 4, and the entire car may be allowed to enter the living space 30. In this case, by providing a sofa in the car, the space inside the car can be used as a living space for box seats. It is desirable that the vehicle is equipped with a storage battery and can be driven automatically.

Of the four outer surfaces 20 of the skeleton structure 2, various panels such as a lattice panel 71 and a solar panel 72 are formed in an area other than the portion where the cap body 32 constituting the front end surface of the infill assembly 3 is arranged. It will be provided. The upper surface of the skeleton structure 2 is covered with a roof 73.

(About the configuration example of the skeleton structure)
A specific configuration example of the skeleton structure 2 will be described with reference to FIGS. 4 and 5. FIG. 4 is an external perspective view showing the skeleton structure 2. FIG. 5 is a diagram showing the unit compartment 23 formed in the skeleton structure 2 by taking it out. The skeleton structure 2 is assembled on-site by, for example, a PCa (precast reinforced concrete) method.

The skeleton structure 2 is composed of a plurality of beam (first beam) 21a extending in the X direction, a plurality of beams (second beam) 21b extending in the Y direction, and a plurality of columns 22 extending in the Z direction. 23 is formed. The X and Y directions intersect (orthogonally) with each other on the horizontal plane, and the Z direction extends vertically and intersects (orthogonally) with the X and Y directions. In the following description, the X and Y directions are also referred to as horizontal directions, and the Z direction is also referred to as vertical directions.

In the present embodiment, the arrangement interval of the first beam 21a in the Y direction and the arrangement interval of the second beam 21b in the X direction are substantially equal. Further, this arrangement interval is substantially equal to the arrangement interval of the first beam 21a and the second beam 21b in the Z direction. Therefore, the unit compartment 23 has a substantially cubic shape. The unit compartment 23 may have a rectangular parallelepiped shape.

More specifically, as shown in FIG. 5, each unit compartment 23 has an upper rectangular frame formed of four beams 21 intersecting each other and a lower rectangular frame formed of four beams 21 intersecting each other. It is composed of a rectangular frame and four pillars 22 connecting the four corners of the upper rectangular frame and the four corners of the lower rectangular frame, respectively. As a result, openings 24 are formed on each of the six surfaces of the unit compartment 23. The four beams 21 forming the upper and lower rectangular frames include a pair of first beams 21a and a pair of second beams 21b.

As shown in FIG. 4, two laterally adjacent unit compartments 23 share two beams 21 and two columns 22 located at the boundary portion. The two unit compartments 23 that are vertically adjacent to each other share four beams 21 located at the boundary portion. The arrangement pitch of the beams 21 is referred to as the basic dimension L0 of the unit compartment 23. The basic dimension L0 of the unit compartment 23 is preferably 2.5 m to 3.5 m, for example, about 3 m.

As described above, the skeleton structure 2 has no floor, ceiling, and side wall, and has a plurality of unit compartments 23 having openings 24 on six sides in the horizontal direction (X direction, Y direction) and the vertical direction (Z direction). ). In the present embodiment, nine unit compartments 23 are arranged on each floor by arranging three unit compartments 23 in the X direction and three unit compartments 23 in the Y direction in a matrix. In addition, three sets of nine unit compartments are arranged in the vertical direction. As a result, nine quadrangular (square) openings 24 of the same size are arranged in a matrix on each outer surface 20 of the skeleton structure 2. Therefore, in the skeleton structure 2, nine insertion spaces for inserting the infill assembly 3 are formed on the outer surface 20.

The vertical dimension L1 of the opening 24 corresponds to the arrangement interval of the beam 21 in the vertical direction, and the horizontal dimension L2 of the opening 24 corresponds to the arrangement interval of the beam 21 in the horizontal direction (horizontal direction).

(About the configuration example of the infill assembly)
A specific configuration example of the infill assembly 3 will be described with reference to FIG. FIG. 6 is an external perspective view showing the infill assembly 3. It is assumed that the left side of the paper surface of FIG. 6 is the front side (front side) of the infill assembly 3, and the right side of the paper surface is the back side (rear side) of the infill assembly 3.

As described above, the infill assembly 3 includes an infill unit 31 extending in the front-rear direction and a cap body 32 attached to the front end portion of the infill unit 31.

The infill unit 31 is made of, for example, CFRP (carbon fiber reinforced plastic) and includes a floor portion 31a, a ceiling portion 31b, a pair of side wall portions 31c, and a rear wall portion 33. The side wall portion 31c is connected to the floor portion 31a and the ceiling portion 31b. The floor portion 31a, the ceiling portion 31b, and the pair of side wall portions 31c form a rectangular tubular portion. It is desirable that the corners of this cylinder are chamfered. The rear wall portion 33 is integrally connected to the rear end of the tubular portion to close the rear opening of the tubular portion.

The infill unit 31 has, for example, a front door 61 serving as an entrance / exit to the living space 30 on one side wall portion 31c, and a translucent window (not shown) on the other side wall portion 31c. The entrance door 61 is provided so as to face the atrium space 5.

The cap body 32 is composed of a substantially rectangular front portion 34 and a tubular side surface portion 35 having a rectangular cross section connected to the four sides of the front portion 34. The cap body 32 is fitted and fixed to the outside of the infill unit 31. That is, the inner side surface of the side surface portion 35 is in surface contact with the outer surface of the infill unit 31, and the front end surface of the infill unit 31 is in contact with the front surface portion 34. It is desirable that the corners of the side surface portion 35 of the cap body 32 are also chamfered.

In this way, the cap body 32 covers the opening at the front end of the infill unit 31, so that the living space 30 becomes a closed space. A translucent window 34a is provided on the front portion 34 facing the living space 30. The window 34a is a fixed window provided on substantially the entire front portion 34. Alternatively, the window 34a is a window that can be opened and closed at least in part.

The portion of the front portion 34 of the cap body 32 other than the window 34a and the side portion 35 are formed of, for example, GRC (glass fiber reinforced cement), aluminum, or steel.

The depth dimension L21 of the side surface portion 35 of the cap body 32 is, for example, about 2 m, but it may be determined between 60 cm or more and less than the basic dimension L0. As described above, since the cap body 32 has a sufficient depth, a part of the living space 30 is provided inside the cap body 32.

It is desirable that the cap body 32 functions as a home appliance. For example, an air conditioner for adjusting the air condition of the living space 30 may be embedded in the side surface portion 35 of the cap body 32, or a lighting fixture for illuminating the living space 30 may be provided. Alternatively, a rainfall sensor may be provided on the cap body 32 so that the window 34a can be automatically opened and closed according to the detection result by the rainfall sensor.

The vertical dimension L11 and the horizontal dimension L12 of the infill unit 31 of the infill assembly 3 are substantially equal to the vertical dimension L1 and the horizontal dimension L2 of the opening 24 formed in the unit compartment 23 of the skeleton structure 2, respectively. As a result, the infill unit 31 is fitted into the unit compartment 23 with no gap (or almost no gap) between the beam 21 and the column 22.

In the present embodiment, since the infill unit 31 is arranged across the plurality of unit compartments 23, the length dimension L13 of the infill unit 31 is equal to or larger than the basic dimension L0 × 2 of the unit compartment 23.

(About how to assemble the building)
Subsequently, a method of assembling the building 1 including the skeleton structure 2 and the plurality of infill assemblies 3 described above will be described with reference to FIGS. 7 to 9. FIG. 7 is a perspective view showing a state in which a part of the infill assembly 3 is fitted in the skeleton structure 2. FIG. 8 is a diagram schematically showing an installation method of the infill assembly 3. FIG. 9 is a perspective view showing a state in which all the infill assemblies 3 are fitted in the skeleton structure 2.

First, a plurality of beams 21 and a plurality of columns 22 are crossed with each other to assemble a skeleton structure 2 as shown in FIG. When the assembly of the skeleton structure 2 is completed, a plurality of unit compartments 23 are formed. The infill assembly 3 is fitted into the unit compartment 23 from the outside of the skeleton structure 2, that is, from the outer surface 20 side. The infill assembly 3 is lifted by a crane or the like and installed in the unit compartment 23.

Focusing on one outer surface 20 of the skeleton structure 2, in the present embodiment, a total of nine opening 24s of the unit compartment 23, 3 in length and 3 in width, are lined up on the outer surface 20. The infill assembly 3 is inserted into three openings 24 located at one lateral end (for example, the left end) of the nine openings 24. Each infill assembly 3 is arranged across two unit compartments 23 in the depth direction.

The assembling of the infill unit 31 and the cap body 32 of the infill assembly 3 may be performed before the insertion into the skeleton structure 2 or may be performed at the time of insertion into the skeleton structure 2. The latter assembly method will be described with reference to FIG.

With reference to FIG. 8A, first, only the infill unit 31 of the infill assembly 3 is fitted into the unit compartment 23 from the outside of the skeleton structure 2. The rear end of the infill unit 31 constitutes the second unit compartment 23 in the insertion direction, the back beam 21 and the pillar 22 (that is, the front beam 21 and the pillar 22 forming the third unit compartment 23). ) (Hereinafter referred to as “predetermined position”), the infill unit 31 is pushed.

In the present embodiment, the length L13 (FIG. 6) of the infill unit 31 of the infill assembly 3 is longer than the basic dimension L0 × 2 of the unit compartment 23 and shorter than the basic dimension L0 × 3. Therefore, the front end of the infill unit 31 protrudes from the unit compartment 23 with the rear end positioned at a predetermined position. That is, the infill unit 31 has a protruding portion 36 that protrudes from the skeleton structure 2 to the outdoor side.

When the infill unit 31 is fitted, the infill unit 31 is fixed to the beam 21 and the column 22 of the skeleton structure 2. After that, the cap body 32 is attached to the protruding portion 36 at the front end of the infill unit 31, and the cap body 32 is fixed to the infill unit 31. In this way, after the infill unit 31 is fixed to the skeleton structure 2, the cap body 32 can be attached to the infill unit 31 to complete the infill assembly 3, so that workability can be improved.

As shown in FIG. 8B, the end surface of the side surface portion 35 of the cap body 32 is fixed so as to be in surface contact with the beam 21 and the column 22 constituting the outer surface 20 of the skeleton structure 2. Thereby, the watertightness and airtightness of the living space 30 can be improved. In this way, the cap body 32 also functions as a sealing material for closing the gap between the front end portion of the infill unit 31 and the skeleton structure 2. A dry or wet sealing material may be separately provided between the cap body 32 and the skeleton structure 2.

As shown in FIG. 9, it is desirable that the length of the infill assembly 3 protruding from the outer surface 20 of the skeleton structure 2, that is, the depth dimension L21 of the cap body 32 is not uniform. In this case, the protruding dimension of the protruding portion 36 of the infill unit 31 may also differ depending on the depth dimension L21 of the cap body 32.

Specifically, it is desirable that the depth dimensions of the cap bodies 32 adjacent to each other in the vertical direction (or horizontal direction) are different from each other. As shown in FIG. 9, the depth dimensions of the three vertical cap bodies 32 protruding from the outer surface 20 on which the skeleton structure 2 is located may all be different. That is, the three vertical cap bodies 32 include a first cap body 32a having a depth dimension L21 as the first dimension and a second cap body 32b having a depth dimension L21 longer than the first dimension. A third cap body 32c having a depth dimension L21 longer than the second dimension may be included.

It should be noted that the plurality of cap bodies 32 included in each of all the infill assemblies 3 incorporated in the skeleton structure 2 include at least the first cap body 32a and the second cap body 32b having different depth dimensions. Good.

When the three infill assemblies 3 are fitted into the three unit compartments 23 located at one end of each outer surface 20 of the skeleton structure 2 in the lateral direction (X direction or Y direction), four infill assemblies 3 are fitted on each floor. The infill assembly 3 is arranged in a 10,000-character shape as shown in FIG.

When the installation of all the infill assemblies 3 in the skeleton structure 2 is completed, at the same time, the arrangement of all the living spaces 30 including the building 1 is completed. In the present embodiment, since the four infill assemblies 3 are arranged in a 10,000-character shape on each floor, the infill assemblies 3 are not arranged in the three vertical unit compartments 23 located in the center of the skeleton structure 2. .. Therefore, the central three vertical unit compartments 23 form a stairwell space 5 that communicates with the piloti space 4.

With reference to FIG. 9, when the installation of the infill assembly 3 is completed, of the nine openings 24 located on each outer surface 20 of the skeleton structure 2, the three vertical openings 24 located at one end in the lateral direction are opened. , It is closed by the front portion 34 of the cap body 32 of the infill assembly 3. The remaining six openings 24 in each outer surface 20 face the outdoors even when the installation of the infill assembly 3 is completed, and the infill unit inserted from the other outer surface 20 through these openings 24. The side wall portion 31c of 31 is exposed. Further, among the nine openings 24 located on the upper surface of the skeleton structure 2, the ceiling portion 31b of the infill unit 31 is exposed from other than the eight openings 24 except the one in the center.

In the present embodiment, the opening 24 of the outer surface 20 where the side wall portion 31c of the infill unit 31 is exposed has a ventilated lattice panel 71 as shown in FIG. 9, or a lattice panel 71 that receives sunlight and receives electrical energy. A solar panel 72 is provided to convert the energy into. The grid panel 71 and the solar panel 72 are fixed to the beams 21 and / or the columns 22 that form the outer surface 20 of the skeleton structure 2. Alternatively, as a form (not shown), an outer wall panel, a greening panel, a window, or the like matching the size of the opening 24 may be provided so as to close the opening 24.

It is desirable that the opening 24 on the upper surface where the ceiling portion 31b of the skeleton structure 2 is exposed is provided with a roof 73 that covers the plurality of openings 24, instead of providing the panel as described above for each opening 24.

In the present embodiment, the roof 73 is configured by connecting a plurality of greening panels. The roof 73 is arranged so as to surround the space above the atrium space 5. It is desirable that a window or door (not shown) that can be opened and closed is provided in the space above the atrium space 5. As a result, as conceptually shown in FIG. 3, the air in the piloti space 4 can be exhausted to the outside through the atrium space 5, and the building 1 can be well ventilated.

As described above, since the building 1 includes the skeleton structure 2, the front surface of the infill assembly 3 can be arranged on each outer surface 20 of the skeleton structure 2. Further, since the cap body 32 that is arranged so as to project to the outdoor side is provided on the front side of the infill assembly 3, unevenness is formed on the side surface of the building 1 and the design of the building 1 can be improved. it can.

Further, since a part of the living space 30 is provided inside the cap body 32 that is arranged so as to project to the outdoor side, it is possible to create an interesting atmosphere as if a part of the living space 30 floats in the air. Can be done.

Further, since the infill assembly 3 of the present embodiment includes the cap body 32 separately from the tubular infill unit 31, it is possible to replace only the cap body 32. Therefore, the atmosphere of the living space 30 can be changed while maintaining the same configuration of the infill unit 31 by simply changing the configuration of the cap body 32. In addition, the appearance of the front surface of the infill assembly 3 can be easily changed.

Further, when the cap body 32 is provided with an air conditioner or the like, the convenience of the living space 30 can be improved by attaching the cap body 32.

Further, since the cap body 32 is mounted on the outside of the infill unit 31, the beam 21 and the pillar 22 forming the outer surface 20 of the skeleton structure 2 can be partially invisible by the cap body 32. Therefore, it is possible to suppress the monotonous image that may occur when the entire skeleton structure 2 is exposed. The distance between the two cap bodies 32 adjacent to each other is 10 cm or less, and preferably 5 cm or less.

Further, since the window 34a is provided on the front surface of the cap body 32, it is possible to produce the appearance that the show window is arranged on the side surface of the building 1. The size, shape, and type (for example, fixed type, open / close type, vertical / skid type, etc.) of the window 34a may be different from each other. Thereby, the appearance design of the building 1 can be further improved.

Further, referring to FIG. 8B, a part 30b of the living space 30 located inside the cap body 32 may be used as a greenhouse or a sofa may be provided on the entire floor surface according to the preference of the resident. It can also be used as a relaxing space. The space 30b inside the cap body 32 may be separated from the adjacent space 30a or may be continuous depending on the intended use. The living space 30 is composed of most of the space 30a in the infill unit 31 and the space 30b inside the cap body 32.

Further, by making the depth dimension of the cap body 32 adjacent in the vertical direction (or the horizontal direction) different, the unevenness of the side surface of the building 1 can be expressed more variously. As a result, the side surface of the building 1 can be shaded, so that the impression of the building 1 can be prevented from becoming monotonous and an original impression can be given. Further, since it is difficult to see the window 34a adjacent to the window 34a from the window 34a, privacy can be ensured.

When the depth dimensions of the two cap bodies 32 adjacent to each other in the vertical direction (or the horizontal direction) are different, it is desirable that the difference between these depth dimensions is 10 cm or more and 90 cm or less.

(About connection of infill assembly)
As described above, since the infill assembly 3 is fitted into the unit compartment 23 having a six-sided opening, the infill assemblies 3 adjacent to each other can be connected to each other. That is, two (or three or more) infill assemblies 3 can also form one dwelling unit.

FIG. 10 is a diagram schematically showing a state in which two infill assemblies 3 adjacent to each other in the lateral direction (X direction or Y direction) are connected. As shown in FIG. 10, one infill assembly 3 and the other infill assembly 3 that are adjacent to each other have a side wall portion 31c of one infill unit 31 and a rear wall portion 33 of the other infill unit 31 adjacent to each other. In this adjacent portion, there is a connecting path 81 capable of going back and forth between them.

As a result, the spaces 30i in the two infill assemblies that are adjacent to each other in the lateral direction can be combined and used as the living space 30 of one dwelling unit. The "adjacent portion" may be a portion in which both wall portions are in close contact with each other even if they are not completely in contact with each other.

When the side wall portion 31c of one infill unit 31 and the rear wall portion 33 of the other infill unit 31 are arranged so as to be separated by, for example, the width dimension of the beam 21, each connecting path 81 is provided as shown in FIG. A connecting passage 82 is provided on the beam 21.

In order to enable such lateral connection between the infill assemblies 3, as shown by an imaginary line in FIG. 6, a communication door for forming a communication path 81 in advance on one of the side wall portions 31c of the infill unit 31. 62 may be provided. When the infill assembly 3 is not connected, the communication door 62 is locked.

FIG. 11 is a diagram schematically showing a state in which two infill assemblies 3 adjacent to each other in the vertical direction (Z direction) are connected to each other. As shown in FIG. 11, the upper infill assembly 3 and the lower infill assembly 3 adjacent to each other have a floor portion 31a of the upper infill unit 31 and a ceiling portion 31b of the lower infill unit 31. It is adjacent to each other, and a connecting path 83 that can be communicated with each other is provided in the adjacent portion. Also in this case, the spaces 30i in the two infill assemblies that are vertically adjacent to each other can be combined and used as the living space 30 of one dwelling unit.

Since the floor portion 31a of the upper infill unit 31 and the ceiling portion 31b of the lower infill unit 31 are arranged so as to be separated by the height dimension of the beam 21, as shown in FIG. 11, the respective connecting passages 83 are arranged. A passage 84 for connecting the above is provided. In this case, a staircase 85 extending from the floor portion 31a of the lower infill unit 31 to the floor portion 31a of the upper infill unit 31 is installed. By doing so, the two vertically adjacent infill assemblies 3 can be used like a maisonette type dwelling unit or a two-story dwelling unit.

In order to enable such vertical connection of the infill assemblies 3, as shown by an imaginary line in FIG. 6, at least one of the floor portion 31a and the ceiling portion 31b can be opened / closed or detached in advance. A lid 63 may be provided. When the infill assembly 3 is not connected in the vertical direction, the lid 63 is locked.

As described above, in the building 1 in the present embodiment, since the skeleton structure 2 in which a plurality of unit compartments 23 having six-sided openings are formed is used as the skeleton, the infill assemblies 3 are connected and disconnected from each other. Can be done flexibly. Therefore, the living space 30 can be freely expanded and contracted without moving according to changes in the lifestyle and family structure of the resident.

Further, since the infill assembly 3 is a box body, the infill assembly 3 can be used as movable property. Therefore, when moving, the infill assembly 3 or the infill unit 31 and the cap 32 can be separately transferred to another building. The size of the infill assembly 3 is preferably a size that can be transferred by a truck.

Further, in the present embodiment, the infill assembly 3 is arranged in a 10,000-character shape on each floor, but since the building 1 includes the skeleton structure 2, the arrangement form of the infill assembly 3 can be selected relatively freely. be able to. For example, a plurality of infill assemblies 3 may be arranged in the same direction on a horizontal plane.

(Modification example)
In the above embodiment, the cap body 32 is fitted to the outside of the infill unit 31 to form the infill assembly 3, but as shown in FIGS. 12A and 12B, the infill unit 31 is formed. The infill assembly 3C may be formed by abutting the cap body 32 against the front end surface of the above. In this case, the living space 30 is composed of the space 30a inside the infill unit 31 and the space 30b inside the cap body 32.

As described above, the infill assembly may include a cap body 32 that is connected to the infill unit 31 and projects from the skeleton structure 2 to the outdoor side, and is provided with a part 30b of the living space 30 inside.

Even in the case of the infill assembly 3C of FIG. 12, it is desirable that the size (vertical and horizontal dimensions) of the cap body 32 is larger than the size (vertical and horizontal dimensions) of the infill unit 31 when viewed from the front side. In this case, the end surface of the side surface portion 35 of the cap body 32 and the outdoor surface (outdoor side surface) of the beam 21 and the beam 22 of the skeleton structure 2 come into surface contact with each other. As a result, the beam 21 and the column 22 constituting the outer surface 20 of the skeleton structure 2 can be partially invisible by the cap body 32, so that the monotony that can occur when the entire skeleton structure 2 skeleton is exposed. Image can be suppressed.

Further, in the present embodiment, the lengths of the plurality of infill assemblies incorporated in the skeleton structure 2, that is, the length dimension L13 of the infill unit 31 are substantially the same, but may be different. For example, an infill assembly 3 in which the length dimension L13 of the infill unit 31 is the basic dimension L0 × 2 of the unit compartment 23 and an infill set in which the length dimension L13 of the infill unit 31 is the basic dimension L0 × 1 of the unit compartment 23. Solids (not shown) may be mixed.

Further, the arrangement form of the infill assembly may be different for each layer composed of the skeleton structure 2.

Further, in the present embodiment, the skeleton structure 2 forms a plurality of unit compartments 23 in both the vertical direction and the horizontal direction, but the skeleton structure 2 may form a plurality of unit compartments 23 in at least one direction. Just do it.

Further, in the present embodiment, the building is provided with the skeleton structure 2 forming a plurality of unit compartments 23 having six-sided openings, but the present invention is not limited. The structure provided in the building may be a cube or rectangular parallelepiped structure in which a plurality of insertion spaces for inserting the infill assembly are formed. For example, like the structure disclosed in Patent Document 1, it may be a structure having a floor and a side wall connected to a beam 21 and a column 22.

As described above, each infill assembly can be transferred. Therefore, the above-mentioned infill assembly can be provided alone.

It should be considered that the embodiments disclosed this time are exemplary in all respects and not restrictive. The scope of the present invention is shown by the scope of claims rather than the above description, and it is intended to include all modifications within the meaning and scope equivalent to the scope of claims.
