[0011] Hereinafter, the building unit connection structure, building, and building construction method according to the embodiment of the present invention will be described with reference to the drawings.

[0012] <First Embodiment> First, with reference to Figures 1 to 12, a connecting structure 300, a building 1, and a method for constructing building 1 according to the first embodiment of the present invention will be described. Building 1 is, for example, a house, a hotel, and an office.

[0013] Figure 1 is a schematic diagram showing a part of building 1. As shown in Figure 1, building 1 comprises a plurality of building units 100a, 100b, 100c, and 100d. Building unit 100a is placed on a foundation 2 constructed on the ground. The foundation 2 is made of concrete, for example. Building unit 100b is stacked on top of building unit 100a. Building unit 100c is placed on the foundation 2, aligned horizontally with building unit 100a. Building unit 100d is stacked on top of building unit 100c.

[0014] Building units 100a and 100c are connected to the foundation 2 using foundation fastening means 3. Foundation fastening means 3 includes an anchor bolt protruding from the foundation 2 and a nut that screws onto the anchor bolt. Building units 100a and 100b, 100a and 100c, 100c and 100d, and 100b and 100d are connected to each other using unit fastening means 4.

Furthermore, building units 100a and 100c, and building units 100b and 100d are connected to each other using a connecting structure 300 (see Figure 9).

[0015] Building units 100a, 100b, 100c, and 100d have substantially the same structure. Hereafter, when referring to building units 100a, 100b, 100c, and 100d collectively, they will simply be referred to as "building unit 100". In Figure 1, the left-right direction of the paper is called the "longitudinal direction", the vertical direction of the paper is called the "inter-beam direction", and the up-down direction of the paper is called the "height direction". The longitudinal direction and the inter-beam direction together are also called the "horizontal direction".

[0016] Figure 2 is a perspective view of building unit 100. As shown in Figure 2, building unit 100 comprises a plurality of column members 10a, 10b, 10c, 10d, a plurality of first beam members 20a, 20b, 20c, 20d, and a plurality of second beam members 30a, 30b, 30c, 30d.

[0017] Column members 10a, 10b, 10c, and 10d extend in the height direction. Column members 10a and 10b are spaced apart from each other in the longitudinal direction. Column members 10c and 10d are spaced apart from each other in the longitudinal direction. Column members 10a and 10c are spaced apart from each other in the inter-beam direction.

The first beam member 20b extends below the column members 10a and 10b, connecting the column members 10a and 10b. The first beam member 20c extends above the column members 10c and 10d, connecting the column members 10c and 10d. The first beam member 20d extends below the column members 10c and 10d, connecting the column members 10c and 10d.

[0020] The second beam members 30a, 30b, 30c, and 30d extend in the direction of the beam span. The second beam members 30a and 30b are spaced apart in the height direction. The second beam members 30c and 30d are spaced apart in the height direction. The second beam members 30a and 30c are spaced apart in the direction of the girder. The second beam members 30b and 30d are spaced apart in the direction of the girder.

[0021] The second beam member 30a extends between the first beam members 20a and 20c, connecting the first beam members 20a and 20c. The second beam member 30a connects the column members 10a and 10c via the first beam members 20a and 20c. The second beam member 30b extends between the first beam members 20b and 20d, connecting the first beam members 20b and 20d. The second beam member 30b connects the column members 10a and 10c via the first beam members 20b and 20d. The second beam member 30c extends between the first beam members 20a and 20c, connecting the first beam members 20a and 20c. The second beam member 30c connects the column members 10a and 10c via the first beam members 20a and 20c. The second beam member 30d extends between the first beam members 20b and 20d, connecting the first beam members 20b and 20d. The second beam member 30d connects the column members 10b and 10d via the first beam members 20b and 20d.

[0022] The relationship between the second beam members 30a, 30b, 30c, and 30d and the column members 10a, 10b, 10c, and 10d may be as follows: The second beam member 30a extends above the column members 10a and 10c and connects them. The second beam member 30b extends below the column members 10a and 10c and connects them. The second beam member 30c extends above the column members 10b and 10d and connects them. The second beam member 30d extends below the column members 10b and 10d and connects them.

[0023] The following describes the structure near the joint between the column member 10c, the first beam member 20c, and the second beam member 30a. The structures near the joint between column member 10a, first beam member 20a, and second beam member 30a, the structures near the joint between column member 10a, first beam member 20b, and second beam member 30b, the structures near the joint between column member 10b, first beam member 20a, and second beam member 30c, the structures near the joint between column member 10b, first beam member 20b, and second beam member 30d, the structures near the joint between column member 10c, first beam member 20d, and second beam member 30b, the structures near the joint between column member 10d, first beam member 20c, and second beam member 30c, and the structures near the joint between column member 10d, first beam member 20d, and second beam member 30d are almost the same as the structures near the joint between column member 10c, first beam member 20c, and second beam member 30a, so their explanations are omitted.

[0024] Figure 3 is an enlarged perspective view of part III shown in Figure 2. Figure 4 is an enlarged side view of building unit 100 viewed from the direction of arrow IV shown in Figure 3. Figure 5 is a cross-sectional view along line VV shown in Figure 4. Figure 6 is a cross-sectional view along line VI-VI shown in Figure 5. Figure 7 is a cross-sectional view along line VII-VII shown in Figure 5.

[0025] As shown in Figures 3, 4, 6, and 7, the first beam member 20c is an H-shaped steel having a web 21 and flanges 22, 23, 24, and 25. Flange 22 extends from the upper end of the web 21 in the direction of the beam. Flange 23 extends from the upper end of the web 21 in the direction of the beam, opposite to flange 22. Flange 24 extends from the lower end of the web 21 in the direction of the beam. Flange 24 is positioned with a gap in the height direction from flange 22. Flange 25 extends from the lower end of the web 21 in the direction of the beam, opposite to flange 24. Flange 25 is positioned with a gap in the height direction from flange 23. Hereinafter, flanges 22 and 23 will also be referred to as "upper flange 22" and "upper flange 23," respectively, and flanges 24 and 25 will also be referred to as "lower flange 24" and "lower flange 25," respectively.

[0026] The web 21 extends above the column member 10c. The lower flanges 24 and 25 are joined to the end face 11 of the column member 10c. Therefore, the lower flanges 24 and 25 function as diaphragms positioned to traverse the column member 10c. When horizontal forces (lateral forces) generated by earthquakes or wind are applied to the first beam member 20c, the horizontal forces are transmitted and distributed across the entire cross-section of the column member 10c. Thus, local deformation of the column member 10c can be suppressed. This prevents the column member 10c from being crushed by the first beam member 20c, and increases the rigidity of the building unit 100.

[0027] The second beam member 30a is an H-shaped steel having a web 31 and flanges 32, 33, 34, and 35. Flange 32 extends from the upper end of the web 31 in the longitudinal direction. Flange 33 extends from the upper end of the web 31 in the longitudinal direction on the opposite side from flange 32. Flange 34 extends from the lower end of the web 31 in the longitudinal direction. Flange 34 is positioned with a gap in the height direction from flange 32. Flange 35 extends from the lower end of the web 31 in the longitudinal direction on the opposite side from flange 34. Flange 35 is positioned with a gap in the height direction from flange 33. Hereinafter, flanges 32 and 33 will also be referred to as "upper flange 32" and "upper flange 33," respectively, and flanges 34 and 35 will also be referred to as "lower flange 34" and "lower flange 35," respectively.

[0028] The upper flanges 32 and 33 of the second beam member 30a are joined to the upper flange 23 of the first beam member 20c. The lower flanges 34 and 35 of the second beam member 30a are joined to the lower flange 25 of the first beam member 20c.

[0029] The building unit 100 further includes rib plates 41, 42, 43, 44, 45, and 46 as reinforcing members provided on the first beam member 20c.

[0030] As shown in Figure 6, the rib plate 41 is provided across the upper flange 22 and lower flange 24 of the first beam member 20c. The rib plate 41 is joined to the upper flange 22 and lower flange 24 by welding, and is also joined to the web 21 by welding. A notch 41a is formed at the upper end of the rib plate 41 on the web 21 side. The notch 41a forms a gap at the corner between the web 21 and the upper flange 22. A notch 41b is formed at the lower end of the rib plate 41 on the web 21 side. The notch 41b forms a gap at the corner between the web 21 and the lower flange 24.

[0031] The rib plate 42 is provided across the upper flange 23 and lower flange 25 of the first beam member 20c. The rib plate 42 is joined to the upper flange 23 and lower flange 25 by welding, and is also joined to the web 21 by welding. Similar to the rib plate 41, the rib plate 42 has notches 42a and 42b formed therein. Notch 42a forms a gap at the corner between the web 21 and the upper flange 23, and notch 42b forms a gap at the corner between the web 21 and the lower flange 25.

[0032] As shown in Figure 7, the rib plate 43 is provided across the web 21 and upper flange 22 of the first beam member 20c. The rib plate 43 is joined to the web 21 and upper flange 22 by welding. A notch 43a is formed at the upper end of the rib plate 43 on the web 21 side. The notch 43a forms a gap at the corner between the web 21 and the upper flange 22.

[0033] The rib plate 44 is provided across the web 21 and upper flange 23 of the first beam member 20c. The rib plate 44 is joined to the web 21 and upper flange 23 by welding. Similar to the rib plate 43, the rib plate 44 has a notch 44a formed therein. The notch 44a forms a gap at the corner between the web 21 and the upper flange 23.

[0034] The rib plate 45 is provided across the web 21 and lower flange 24 of the first beam member 20c. The rib plate 45 is joined to the web 21 and lower flange 24 by welding. A notch 45a is formed at the lower end of the rib plate 45 on the web 21 side. The notch 45a forms a gap at the corner between the web 21 and the lower flange 24.

[0035] The rib plate 46 is provided across the web 21 and lower flange 25 of the first beam member 20c. The rib plate 46 is joined to the web 21 and lower flange 25 by welding. Similar to the rib plate 45, the rib plate 46 has a notch 46a formed therein. The notch 46a forms a gap at the corner between the web 21 and the lower flange 25.

[0036] As shown in Figures 4 and 7, rib plates 43 and 45 are spaced apart in the height direction. Rib plates 44 and 46 are spaced apart in the height direction. As shown in Figure 5, multiple rib plates 45 are spaced apart in the longitudinal direction. Multiple rib plates 46 are spaced apart in the longitudinal direction. Rib plate 41 is positioned between adjacent rib plates 45 in the longitudinal direction. Rib plate 42 is positioned between adjacent rib plates 46 in the longitudinal direction. As shown in Figures 5 and 7, rib plates 45 and 46 are located on the extension of column member 10c.

[0037] Although not shown in the diagram, multiple rib plates 43 are provided at intervals in the longitudinal direction. Multiple rib plates 44 are provided at intervals in the longitudinal direction. Rib plate 41 is positioned between adjacent rib plates 43 in the longitudinal direction. Rib plate 42 is positioned between adjacent rib plates 44 in the longitudinal direction.

[0038] Figure 8 is a schematic diagram illustrating the deformation that occurs in the building unit 100 when a horizontal force is applied to the first beam member 20c. In Figure 8, the external shape of the deformed building unit 100 is shown by a dashed line, and for the sake of explanation, the deformation of the building unit 100 is exaggerated. As shown in Figure 8, when a horizontal force is applied to the first beam member 20c, a bending moment is generated in the column member 10c, causing one side in the beam direction to be compressed and the other side to be stretched. If the lower flanges 24 and 25 deform so that they tilt relative to the web 21, the bending moment generated in the column member 10c will increase, and local deformation may occur.

[0039] In the building unit 100, the rib plates 45 and 46 are located on the extension of the column member 10c. Therefore, the rib plates 45 and 46 hold the lower flanges 24 and 25 and the web 21 against the compression and tension occurring in the column member 10c, and prevent the lower flanges 24 and 25 from tilting relative to the web 21. Thus, the bending moment occurring in the column member 10c can be suppressed. As a result, local deformation of the column member 10c can be further suppressed, and the rigidity of the building unit 100 can be further increased.

[0040] In the above embodiments, the rib plates 41, 42, 43, 44, 45, and 46 are provided to reinforce the column members 10a, 10b, 10c, and 10d. In the present invention, it is sufficient that the rib plates 41, 42, 43, 44, 45, and 46 are provided to reinforce at least one of the column members 10a, 10b, 10c, and 10d.

[0041] As shown in Figure 1, the lower flanges 24 and 25 of the first beam member 20c in the building unit 100a face the foundation 2. The anchor bolts of the foundation fastening means 3 pass through the lower flanges 24 and 25. By screwing nuts onto the anchor bolts, the foundation fastening means 3 fastens the building unit 100a to the foundation 2.

[0042] Figure 9 is an enlarged perspective view of building 1 showing the periphery of the connecting structure 300. Figure 10 is an enlarged plan view of the periphery of the connecting structure 300 from the direction of arrow X shown in Figure 9. Figure 11 is a cross-sectional view along the line XI-XI shown in Figure 10. Figures 9, 10, and 11 show a portion of building unit 100a and a portion of building unit 100c.

[0043] As shown in Figure 9, the second beam member 30d of building unit 100a is an H-shaped steel beam having a web 31 and flanges 32, 33, 34, and 35, similar to the second beam member 30a (see Figure 3). The second beam member 30b of building unit 100c is an H-shaped steel beam having a web 31 and flanges 32, 33, 34, and 35, similar to the second beam member 30a (see Figure 3).

[0044] As shown in Figures 9 and 11, the web 31 of building unit 100a and the web 31 of building unit 100c are spaced apart from each other in the longitudinal direction. The flange 32 of building unit 100a extends from the web 31 of building unit 100a toward the flange 32 of building unit 100c. The flange 32 of building unit 100c extends from the web 31 of building unit 100c toward the flange 32 of building unit 100a.

[0045] The connecting structure 300 comprises a plate member 310, a first fastening means 320, and a second fastening means 330. The plate member 310 is superimposed on the flange 32 of building unit 100a and the flange 32 of building unit 100c.

[0046] The plate member 310 has a first through hole 311 and a second through hole 312. The first through hole 311 and the second through hole 312 penetrate the plate member 310 in the height direction. The flange 32 of the building unit 100a has a first through hole 32a. The first through hole 32a penetrates the flange 32 of the building unit 100a in the height direction. The first through hole 32a leads to the first through hole 311. The flange 32 of the building unit 100c has a second through hole 32b. The second through hole 32b penetrates the flange 32 of the building unit 100c in the height direction. The second through hole 32b leads to the second through hole 312.

[0047] The first fastening means 320 includes a bolt 321 inserted into the first through hole 311 and the first through hole 32a, and a nut 322 that is screwed onto the bolt 321. When the nut 322 is screwed onto the bolt 321 inserted into the first through hole 311 and the first through hole 32a, the plate member 310 and the flange 32 of the building unit 100a are fastened together.

[0048] The second fastening means 330 includes a bolt 331 inserted into the second through hole 312 and the second through hole 32b, and a nut 332 that is screwed onto the bolt 331. When the nut 332 is screwed onto the bolt 331 inserted into the second through hole 312 and the second through hole 32b, the plate member 310 and the flange 32 of the building unit 100c are fastened together.

[0049] Thus, in this embodiment, the plate member 310 is overlapped and fastened to the flange 32 of the building unit 100a, and the plate member 310 is overlapped and fastened to the flange 32 of the building unit 100c. Therefore, the building unit 100a and the building unit 100c can be connected without providing any member between the flange 32 of the building unit 100a and the flange 32 of the building unit 100c. This makes it possible to reduce the distance between the building unit 100a and the building unit 100c.

[0050] Furthermore, the connecting structure 300 allows the building unit 100a and the building unit 100c to be connected near the column member 10d and the first beam member 20d of the building unit 100a, and near the column member 10c and the first beam member 20d of the building unit 100c. Therefore, the rigidity of the building 1 can be increased.

[0051] Figure 12 is a diagram illustrating the construction method of building 1 and is shown in correspondence with Figure 11. In the construction method of building 1 according to this embodiment, first, building units 100a, 100b, 100c, and 100d are assembled. Building units 100a, 100b, 100c, and 100d are assembled, for example, in a factory.

[0052] Next, building units 100a, 100b, 100c, and 100d are transported to the site. As shown in Figure 1, building units 100a and 100c are placed on the foundation 2. This arranges building units 100a and 100c in the longitudinal direction. Building units 100a and 100c are connected to the foundation 2 using the foundation fastening means 3. Building units 100a and 100c are connected to each other using the unit fastening means 4 and the connecting structure 300.

[0053] As shown in Figure 12, the connection between building unit 100a and building unit 100c using the connecting structure 300 utilizes an opening 31a formed in the web 31 of building unit 100a. The opening 31a may be formed in the web 31 of the second beam member 30d before assembling building unit 100a, or it may be formed in the web 31 of the second beam member 30d after assembling building unit 100a. It is preferable that the opening 31a be formed before placing building unit 100a on the foundation 2.

[0054] The building units 100a and 100c are placed on the foundation 2, and after aligning the building units 100a and 100c in the longitudinal direction, the bolts 321 are inserted into the first through-holes 311 of the plate member 310 and the first through-holes 32a of the flange 32 of the building unit 100a. Next, the nuts 322 are placed between the web 31 of the building unit 100a and the web 31 of the building unit 100c through the opening 31a. Then, the hands or jigs of a worker are inserted through the opening 31a to hold the nuts 322, and the bolts 321 and nuts 322 are rotated relative to each other to screw the bolts 321 and nuts 322 together. In this way, the plate member 310 and the flange 32 of the building unit 100a are fastened together using the first fastening means 320.

[0055] Next, the bolt 331 is inserted into the second through-hole 312 of the plate member 310 and the second through-hole 32b of the flange 32 of the building unit 100c. Then, the nut 332 is placed between the web 31 of the building unit 100a and the web 31 of the building unit 100c through the opening 31a. After that, the worker's hand or a jig is inserted through the opening 31a to hold the nut 332, and the bolt 331 and nut 332 are rotated relative to each other to screw the bolt 331 and nut 332 together. This fastens the plate member 310 and the flange 32 of the building unit 100c using the second fastening means 330. Before fastening the plate member 310 and the flange 32 of the building unit 100a using the first fastening means 320, the plate member 310 and the flange 32 of the building unit 100c may be fastened using the second fastening means 330.

[0056] Next, the opening 31a is closed. Specifically, a plate having approximately the same outer shape as the opening 31a is prepared, and this plate is fitted into the opening 31a. Then, the opening 31a is closed by welding the plate to the periphery of the opening 31a. By closing the opening 31a, the rigidity of the web 31 of the building unit 100a can be increased.

[0057] In the example shown in Figure 12, the opening 31a is formed only in the web 31 of building unit 100a. The opening 31a may also be formed in the web 31 of building unit 100c. The opening 31a may be formed in both the web 31 of building unit 100a and the web 31 of building unit 100c.

[0058] Next, as shown in Figure 1, building unit 100b is stacked on top of building unit 100a, and building unit 100d is stacked on top of building unit 100c. This arranges building units 100b and 100d in the longitudinal direction. Building units 100b and 100d are connected to each other using the unit fastening means 4 and the connecting structure 300. The connection of building units 100b and 100d using the connecting structure 300 is almost the same as the connection of building unit 100a and building unit 100c, so a detailed explanation is omitted here.

[0059] With the above steps completed, the construction of building 1 is finished. The connection of building units 100a and 100c to foundation 2 may be performed after stacking building unit 100b on building unit 100a and building unit 100d on building unit 100c. The connection of building unit 100a and building unit 100c may be performed after stacking building unit 100b on building unit 100a and building unit 100d on building unit 100c.

[0060] <First modified example of the connecting structure> Figure 13 is a cross-sectional view of the connecting structure 400 according to the first modified example, and is shown in correspondence with Figure 11. In the connecting structure 300 shown in Figure 11, the bolt 321 of the first fastening means 320 is inserted from above into the first through hole 311 of the plate member 310 and the first through hole 32a of the building unit 100a, and the nut 322 of the first fastening means 320 is screwed onto the bolt 321 from below. The bolt 331 of the second fastening means 330 is inserted from above into the second through hole 312 of the plate member 310 and the second through hole 32b of the building unit 100c, and the nut 332 of the second fastening means 330 is screwed onto the bolt 331 from below.

[0061] In the connecting structure 400, as shown in Figure 13, the bolt 321 of the first fastening means 320 is inserted from below into the first through hole 32a of the building unit 100a and the first through hole 311 of the plate member 310, and the nut 322 of the first fastening means 320 is screwed onto the bolt 321 from above. The bolt 331 of the second fastening means 330 is inserted from below into the second through hole 32b of the building unit 100c and the second through hole 312 of the plate member 310, and the nut 332 of the second fastening means 330 is screwed onto the bolt 331 from above.

[0062] In the connecting structure 400, the distance between building unit 100a and building unit 100c can be narrowed. Furthermore, building unit 100a and building unit 100c can be connected near the column member 10d and first beam member 20d of building unit 100a, and near the column member 10c and first beam member 20d of building unit 100c. Therefore, the rigidity of building 1 can be increased.

[0063] The construction method for building 1 equipped with the connecting structure 400 is almost the same as the construction method for building 1 equipped with the connecting structure 300, except that bolts 321 and 331 are inserted between the web 31 of building unit 100a and the web 31 of building unit 100c through an opening 31a formed in the web 31 of building unit 100a. Therefore, a detailed explanation of the construction method for building 1 equipped with the connecting structure 400 is omitted here.

[0064] <Second modified example of the connecting structure> Figure 14 is a cross-sectional view of the connecting structure 500 according to the second modified example, and is shown in correspondence with Figure 12. Figure 14 shows the state before the plate member 310 is fastened to the flange 32 of building unit 100a and the flange 32 of building unit 100c.

[0065] In the connecting structure 300 shown in Figure 12, the nut 322 of the first fastening means 320 is not fixed to the flange 32 of the building unit 100a when it is not screwed onto the bolt 321. Similarly, the nut 332 of the second fastening means 330 is not fixed to the flange 32 of the building unit 100c when it is not screwed onto the bolt 331.

[0066] In the connecting structure 500, as shown in Figure 14, the nut 322 of the first fastening means 320 is fixed to the flange 32 of the building unit 100a by welding. Similarly, the nut 332 of the second fastening means 330 is fixed to the flange 32 of the building unit 100c by welding. In other words, the nuts 322 and 332 are fixed to the flanges 32 of the building units 100a and 100c via weld beads 523 and 533, respectively. The nuts 322 and 332 may also be fixed to the flanges 32 of the building units 100a and 100c by methods other than welding. The nuts 322 and 332 only need to be fixed to the flanges 32 of the building units 100a and 100c when they are not screwed onto the bolts 321 and 331.

[0067] The nuts 322 and 332 may be fixed to the flanges 32 of the second beam members 30d and 30b before assembling the building units 100a and 100c, or they may be fixed to the flanges 32 of the second beam members 30d and 30b after assembling the building units 100a and 100c. The nuts 322 and 332 only need to be fixed to the flanges 32 of the second beam members 30d and 30b before placing the building units 100a and 100c on the foundation 2 and aligning them in the longitudinal direction.

[0068] In the connecting structure 500, the distance between building unit 100a and building unit 100c can be narrowed. Furthermore, building unit 100a and building unit 100c can be connected near the column member 10d and first beam member 20d of building unit 100a, and near the column member 10c and first beam member 20d of building unit 100c. Therefore, the rigidity of building 1 can be increased.

[0069] In the connecting structure 500, the nuts 322 and 332 of the first fastening means 320 and the second fastening means 330 are fixed to the flanges 32 of the building units 100a and 100c when they are not screwed onto the bolts 321 and 331. Therefore, the work of inserting the nuts 322 and 332 between the webs 31 of the building units 100a and 100c through the opening 31a (see Figure 12) is eliminated. Also, the work of holding the nuts 322 and 332 with the bolts 321 and 331 by hand or with a jig is eliminated when screwing the nuts 322 and 332 onto the bolts 321 and 331. In other words, the opening 31a (see Figure 12) required in the connecting structures 300 and 400 is eliminated. Consequently, the building units 100a and 100c can be connected more easily.

[0070] The construction method for building 1 equipped with the connecting structure 500 is almost the same as the construction method for building 1 equipped with the connecting structure 300, except that there is no step of inserting nuts 322 and 332 from the opening 31a (see Figure 12) between the webs 31 of building units 100a and 100c, and there is no step of holding the nuts 322 and 332 with the bolts 321 and 331 by the worker's hands or a jig. Therefore, a detailed explanation of the construction method for building 1 equipped with the connecting structure 500 is omitted here.

[0071] <Third modified example of the connecting structure> Figure 15 is a cross-sectional view of the connecting structure 600 according to the third modified example, and is shown in correspondence with Figure 12. Figure 15 shows the state before the plate member 310 is fastened to the flange 32 of building unit 100a and the flange 32 of building unit 100c.

[0072] In the connecting structure 500 shown in Figure 14, the nuts 322 and 332 of the first fastening means 320 and the second fastening means 330 are fixed to the flanges 32 of the building units 100a and 100c when they are not screwed onto the bolts 321 and 331.

[0073] In the connecting structure 600, as shown in Figure 15, the bolts 321 and 331 of the first fastening means 320 and the second fastening means 330 are fixed to the flanges 32 of the building units 100a and 100c when they are not screwed into the nuts 322 and 332. The bolts 321 and 331 are fixed to the flanges 32 of the building units 100a and 100c, respectively, for example, via weld beads 523 and 533. The bolts 321 and 331 may also be fixed to the flanges 32 of the building units 100a and 100c by methods other than welding.

[0074] The bolts 321 and 331 may be fixed to the flanges 32 of the second beam members 30d and 30b before assembling the building units 100a and 100c, or they may be fixed to the flanges 32 of the second beam members 30d and 30b after assembling the building units 100a and 100c. The bolts 321 and 331 only need to be fixed to the flanges 32 of the second beam members 30d and 30b before placing the building units 100a and 100c on the foundation 2 and aligning them in the longitudinal direction.

[0075] In the connecting structure 600, the distance between building unit 100a and building unit 100c can be narrowed. Furthermore, building unit 100a and building unit 100c can be connected near the column member 10d and first beam member 20d of building unit 100a, and near the column member 10c and first beam member 20d of building unit 100c. Therefore, the rigidity of the building 1 can be increased. Moreover, building unit 100a and building unit 100c can be connected more easily.

[0076] The construction method for building 1 equipped with the connecting structure 600 is almost the same as the construction method for building 1 equipped with the connecting structure 400, except that there is no step of inserting bolts 321 and 331 from the opening 31a (see Figure 12) between the webs 31 of building units 100a and 100c, and there is no step of holding the bolts 321 and 331 with the workers' hands or jigs when screwing the nuts 322 and 332 together with the bolts 321 and 331. Therefore, a detailed explanation of the construction method for building 1 equipped with the connecting structure 600 is omitted here.

[0077] <Fourth modified example of the connecting structure> Figure 16 is a cross-sectional view of the connecting structure 700 according to the fourth modified example, and is shown in correspondence with Figure 12. Figure 16 shows the state before the plate member 310 is fastened to the flange 32 of building unit 100a and the flange 32 of building unit 100c.

[0078] In the connecting structure 500 shown in Figure 14, the nuts 322 and 332 of the first fastening means 320 and the second fastening means 330 are fixed to the flanges 32 of the building units 100a and 100c.

[0079] In the connecting structure 700, as shown in Figure 16, the first fastening means 720 and the second fastening means 730 are provided with female screw holes 722 and 732, respectively, instead of nuts 322 and 332. The female screw holes 722 and 732 are formed in the flanges 32 of the building units 100a and 100c, respectively. The bolts 321 and 331 are screwed into the female screw holes 722 and 732, respectively.

[0080] The female screw holes 722 and 732 may be formed in the flanges 32 of the second beam members 30d and 30b before assembling the building units 100a and 100c, or they may be formed in the flanges 32 of the second beam members 30d and 30b after assembling the building units 100a and 100c. The female screw holes 722 and 732 only need to be formed in the flanges 32 of the second beam members 30d and 30b before placing the building units 100a and 100c on the foundation 2 and aligning them in the longitudinal direction. The female screw holes 722 and 732 are formed in the flanges 32 of the second beam members 30d and 30b by, for example, threading.

[0081] In the connecting structure 700, the distance between building unit 100a and building unit 100c can be narrowed. Furthermore, building unit 100a and building unit 100c can be connected near the column member 10d and first beam member 20d of building unit 100a, and near the column member 10c and first beam member 20d of building unit 100c. Therefore, the rigidity of building 1 can be increased. Moreover, since the opening 31a (see Figure 12) required in the connecting structures 300 and 400 is not necessary, building unit 100a and building unit 100c can be connected more easily.

[0082] The construction method for building 1 equipped with the connecting structure 700 is almost the same as the construction method for building 1 equipped with the connecting structure 500, except that bolts 321 and 331 are screwed into female screw holes 722 and 732. Therefore, a detailed explanation of the construction method for building 1 equipped with the connecting structure 700 is omitted here.

[0083] Although not shown in the diagram, instead of flanges 32 on building units 100a and 100c, female screw holes 722 and 732 may be formed on the plate member 310. In this case, bolts 321 and 331 are inserted between the webs 31 of building units 100a and 100c and screwed into the female screw holes 722 and 732 from below. Therefore, it is necessary to form an opening 31a (see Figure 12) on the web 31 of building unit 100a.

[0084] <Fifth modified example of the connecting structure> Figure 17 is a cross-sectional view of the connecting structure 800 according to the fifth modified example, and is shown in correspondence with Figure 12. Figure 17 shows the state before the plate member 310 is fastened to the flange 32 of building unit 100a and the flange 32 of building unit 100c.

[0085] In the connecting structure 600 shown in Figure 15, the bolts 321 and 331 of the first fastening means 320 and the second fastening means 330 are fixed to the flanges 32 of the building units 100a and 100c.

[0086] In the connecting structure 800, as shown in Figure 17, the first fastening means 820 and the second fastening means 830 are equipped with shafts 821 and 831, respectively, instead of bolts 321 and 331. The shafts 821 and 831 are provided on the flanges 32 of the building units 100a and 100c, respectively. Male threads are formed on the outer circumference of the shafts 821 and 831. Nuts 322 and 332 are screwed onto the shafts 821 and 831, respectively.

[0087] The shaft portions 821 and 831 may be provided on the flanges 32 of the second beam members 30d and 30b before assembling the building units 100a and 100c, or they may be provided on the flanges 32 of the second beam members 30d and 30b after assembling the building units 100a and 100c. The shaft portions 821 and 831 only need to be provided on the flanges 32 of the second beam members 30d and 30b before placing the building units 100a and 100c on the foundation 2 and arranging them in the longitudinal direction.

[0088] The shaft portions 821 and 831 are attached to the flanges 32 of the building units 100a and 100c by welding, respectively. In other words, the shaft portions 821 and 831 are attached to the flanges 32 of the building units 100a and 100c via weld beads 823 and 833, respectively. The shaft portions 821 and 831 may also be attached to the flanges 32 of the building units 100a and 100c by methods other than welding.

[0089] In the connecting structure 800, the distance between building unit 100a and building unit 100c can be narrowed. Furthermore, building unit 100a and building unit 100c can be connected near the column member 10d and first beam member 20d of building unit 100a, and near the column member 10c and first beam member 20d of building unit 100c. Therefore, the rigidity of building 1 can be increased. Moreover, since the opening 31a (see Figure 12) required in the connecting structures 300 and 400 is not necessary, building unit 100a and building unit 100c can be connected more easily.

[0090] The construction method for building 1 equipped with the connecting structure 800 is almost the same as the construction method for building 1 equipped with the connecting structure 600, except that nuts 322 and 332 are screwed onto shafts 821 and 831. Therefore, a detailed explanation of the construction method for building 1 equipped with the connecting structure 800 is omitted here.

[0091] Although not shown in the diagram, the shaft portions 821 and 831 may be provided on the plate member 310 instead of the flanges 32 of the building units 100a and 100c. In this case, the nuts 322 and 332 will be placed between the webs 31 of the building units 100a and 100c and screwed onto the shaft portions 821 and 831 from below. Therefore, it is necessary to form an opening 31a (see Figure 12) in the web 31 of the building unit 100a.

[0092] The connecting structures 300, 400, 500, 600, 700, and 800 may be used in combination. For example, the first fastening means 320 of the connecting structure 300 may be used to fasten the plate member 310 to the flange 32 of the building unit 100a, and the second fastening means 330 of the connecting structure 400 may be used to fasten the plate member 310 to the flange 32 of the building unit 100c. The first fastening means 320 of the connecting structure 500 may be used to fasten the plate member 310 to the flange 32 of the building unit 100a, and the second fastening means 330 of the connecting structure 600 may be used to fasten the plate member 310 to the flange 32 of the building unit 100c. The first fastening means 720 of the connecting structure 700 may be used to fasten the plate member 310 to the flange 32 of the building unit 100a, and the second fastening means 830 of the connecting structure 800 may be used to fasten the plate member 310 to the flange 32 of the building unit 100c.

[0093] <Sixth variation of the connecting structure> Figure 18 is a partially enlarged plan view of the connecting structure 900 according to the sixth modified example, and is shown in correspondence with Figure 10. Figure 19 is a cross-sectional view along the line XIX-XIX shown in Figure 18.

[0094] In the connecting structures 300, 400, 500, 600, 700, and 800, as shown in Figures 10 to 17, the building units 100a and 100c are connected to each other without any gaps. Specifically, the end face of the flange 32 of building unit 100a and the end face of the flange 32 of building unit 100c are in contact with each other. Although not shown in the illustration, the end face of the flange 34 of building unit 100a and the end face of the flange 34 of building unit 100c are in contact with each other.

[0095] In the connecting structure 900, as shown in Figures 18 and 19, the building units 100a and 100c are connected to each other with a gap in the longitudinal direction. Specifically, a gap G is provided between the end face of the flange 32 of building unit 100a and the end face of the flange 32 of building unit 100c. Although not shown in the figures, a gap G is also provided between the end face of the flange 34 of building unit 100a and the end face of the flange 34 of building unit 100c. The size of the gap G in the longitudinal direction is, for example, 100 mm or less. More preferably, the size of the gap G in the longitudinal direction is 10 mm or less.

[0096] The construction method for building 1 equipped with the connecting structure 900 is almost the same as the construction method for building 1 equipped with the connecting structure 300 (Figure 12). Therefore, a detailed explanation of the construction method for building 1 equipped with the connecting structure 900 is omitted here.

[0097] If the size of the gap G in the longitudinal direction is 100 mm or less, it is difficult for workers to reach into the gap G. Even if workers can reach into the gap G, it is difficult for them to work in the space between the web 31 of building unit 100a and the web 31 of building unit 100c.

[0098] In the construction method of building 1 equipped with the connecting structure 900, bolts 321 and nuts 322, and bolts 331 and nuts 332 are screwed together using the opening 31a (see Figure 12) formed in the web 31 of building unit 100a. Therefore, the plate member 910 and the flange 32 of building unit 100a, and the plate member 910 and the flange 32 of building unit 100a can be fastened without inserting a hand into the gap G. Thus, the gap G between building unit 100a and building unit 100c can be made 100 mm or less. In addition, building unit 100a and building unit 100c can be connected near the column member 10d and the first beam member 20d of building unit 100a, and near the column member 10c and the first beam member 20d of building unit 100c. Thus, the rigidity of building 1 can be increased.

[0099] <Seventh variation of the connected structure> Figure 20 is a partially enlarged plan view of the connecting structure 1000 according to the seventh modified example, and is shown in correspondence with Figure 10. Figure 21 is a cross-sectional view along the line XXI-XXI shown in Figure 20.

[0100] In the connecting structure 300, as shown in Figure 10, the bolt 321 of the first fastening means 320 penetrates the flange 32 of the building unit 100a and fastens the flange 32 to the plate member 310, and the bolt 332 of the second fastening means 330 penetrates the flange 32 of the building unit 100c and fastens the flange 32 to the plate member 310.

[0101] In the connecting structure 1000, as shown in Figures 20 and 21, the bolt 321 of the first fastening means 320 penetrates the flange 33 of the building unit 100a and fastens the flange 33 to the plate member 1010. Specifically, a first through-hole 33a is formed in the flange 33 of the building unit 100a. The first through-hole 33a penetrates the flange 33 of the building unit 100a in the height direction. The first through-hole 33a leads to a first through-hole 311 of the plate member 1010. When a nut 322 is screwed onto the bolt 321 inserted into the first through-hole 311 and the first through-hole 33a, the plate member 1010 and the flange 33 of the building unit 100a are fastened together.

[0102] The bolt 331 of the second fastening means 330 penetrates the flange 33 of the building unit 100c and fastens the flange 33 to the plate member 1010. Specifically, a second through-hole 33b is formed in the flange 33 of the building unit 100c. The second through-hole 33b penetrates the flange 33 of the building unit 100c in the height direction. The second through-hole 33b leads to a second through-hole 312 of the plate member 1010. When a nut 332 is screwed onto the bolt 331 inserted into the second through-hole 312 and the second through-hole 33b, the plate member 1010 and the flange 33 of the building unit 100c are fastened together.

[0103] In the examples shown in Figures 20 and 21, a gap G is provided between the end face of the flange 32 of building unit 100a and the end face of the flange 32 of building unit 100c. The end face of the flange 32 of building unit 100a and the end face of the flange 32 of building unit 100c may be in contact with each other. In other words, building units 100a and 100c may be connected to each other without a gap G being provided.

[0104] In the connecting structure 1000, the distance between building unit 100a and building unit 100c can be narrowed. Furthermore, building unit 100a and building unit 100c can be connected near the column member 10d and first beam member 20d of building unit 100a, and near the column member 10c and first beam member 20d of building unit 100c. Therefore, the rigidity of building 1 can be increased. Moreover, since the opening 31a (see Figure 12) required in connecting structures 300 and 400 is not necessary, building unit 100a and building unit 100c can be connected more easily.

[0105] The construction method for building 1 equipped with the connecting structure 1000 is almost the same as the construction method for building 1 equipped with the connecting structure 300 (Figure 12). Therefore, a detailed explanation of the construction method for building 1 equipped with the connecting structure 1000 is omitted here.

[0106] The first fastening means 320, 720, 820 and the second fastening means 330, 730, 830 of the connecting structures 400, 500, 600, 700, and 800 may be used as the first fastening means 320 and the second fastening means 330 of the connecting structure 1000. For example, the first fastening means 320 of the connecting structure 400 may be used to fasten the plate member 1010 to the flange 33 of the building unit 100a, and the second fastening means 330 of the connecting structure 400 may be used to fasten the plate member 1010 to the flange 33 of the building unit 100c. The first fastening means 320 of the connecting structure 500 may be used to fasten the plate member 1010 to the flange 33 of the building unit 100a, and the second fastening means 330 of the connecting structure 600 may be used to fasten the plate member 1010 to the flange 33 of the building unit 100c. The first fastening means 720 of the connecting structure 700 may be used to fasten the plate member 1010 to the flange 33 of the building unit 100a, and the second fastening means 830 of the connecting structure 800 may be used to fasten the plate member 1010 to the flange 33 of the building unit 100c.

[0107] <Eighth variation of the connecting structure> Figure 22 is a partially enlarged plan view of the connecting structure 1100 according to the eighth modified example, and is shown in correspondence with Figure 10. Figure 23 is a cross-sectional view along the line XXIII-XXIII shown in Figure 22.

[0108] In the connecting structure 1000, as shown in Figure 21, the bolt 332 of the second fastening means 330 penetrates the flange 33 of the building unit 100c and fastens the flange 33 to the plate member 1010.

[0109] In the connecting structure 1100, as shown in Figures 22 and 23, the bolt 331 of the second fastening means 330 penetrates the flange 32 of the building unit 100c and fastens the flange 32 to the plate member 1110. Specifically, a second through-hole 32b is formed in the flange 32 of the building unit 100c. The second through-hole 32b penetrates the flange 33 of the building unit 100c in the height direction. The second through-hole 32b leads to a second through-hole 312 of the plate member 1110. When a nut 332 is screwed onto the bolt 331 inserted into the second through-hole 312 and the second through-hole 32b, the plate member 1110 and the flange 33 of the building unit 100c are fastened together.

[0110] In the examples shown in Figures 22 and 23, a gap G is provided between the end face of the flange 32 of building unit 100a and the end face of the flange 32 of building unit 100c. The end face of the flange 32 of building unit 100a and the end face of the flange 32 of building unit 100c may be in contact with each other. In other words, building units 100a and 100c may be connected to each other without a gap G being provided.

[0111] In the connecting structure 1100, the distance between building unit 100a and building unit 100c can be narrowed. Furthermore, building unit 100a and building unit 100c can be connected near the column member 10d and first beam member 20d of building unit 100a, and near the column member 10c and first beam member 20d of building unit 100c. Therefore, the rigidity of building 1 can be increased.

[0112] The construction method for building 1 equipped with the connecting structure 1000 is almost the same as the construction method for building 1 equipped with the connecting structure 300 (Figure 12). Therefore, a detailed explanation of the construction method for building 1 equipped with the connecting structure 1000 is omitted here.

[0113] The first fastening means 320, 720, 820 and the second fastening means 330, 730, 830 of the connecting structures 400, 500, 600, 700, and 800 may be used as the first fastening means 320 and the second fastening means 330 of the connecting structure 1100. For example, the first fastening means 320 of the connecting structure 400 may be used to fasten the plate member 1110 to the flange 33 of the building unit 100a, and the second fastening means 330 of the connecting structure 400 may be used to fasten the plate member 1110 to the flange 32 of the building unit 100c. The first fastening means 320 of the connecting structure 500 may be used to fasten the plate member 1110 to the flange 33 of the building unit 100a, and the second fastening means 330 of the connecting structure 600 may be used to fasten the plate member 1110 to the flange 32 of the building unit 100c. The first fastening means 720 of the connecting structure 700 may be used to fasten the plate member 1110 to the flange 33 of the building unit 100a, and the second fastening means 830 of the connecting structure 800 may be used to fasten the plate member 1110 to the flange 32 of the building unit 100c.

[0114] The bolt 321 of the first fastening means 320 may pass through the flange 32 of the building unit 100a and fasten the flange 32 to the plate member 1110, and the bolt 331 of the second fastening means 330 may pass through the flange 33 of the building unit 100c and fasten the flange 33 to the plate member 1110.

[0115] The above embodiment described the case in which building units 100a and 100c arranged in the longitudinal direction are connected. The present invention is also applicable to the connection of building units arranged in the transverse direction.

[0116] <Second Embodiment> Next, with reference to Figures 24 to 29, the building unit 200 and connecting structure 1200 according to the second embodiment of the present invention will be described. In the following, the differences from the first embodiment will be mainly described, and the same or equivalent components as those described in the first embodiment will be denoted by the same reference numerals in the figures and their descriptions will be omitted. The schematic diagram of the building 1 equipped with the building unit 200 is substantially the same as the schematic diagram shown in Figure 1, so its illustration will be omitted here.

[0117] Figure 24 is a perspective view of the building unit 200. In the building unit 100 according to the first embodiment, as shown in Figure 2, the first beam members 20a and 20c extend above the column members 10a, 10b, 10c, and 10d, and the first beam members 20b and 20d extend below the column members 10a, 10b, 10c, and 10d. In the building unit 200 according to this embodiment, as shown in Figure 24, the first beam members 20a and 20c do not extend above the column members 10a, 10b, 10c, and 10d, and the first beam members 20b and 20d do not extend below the column members 10a, 10b, 10c, and 10d. In this respect, this embodiment differs from the first embodiment.

[0118] The building unit 200 includes reinforcing members 240 positioned above and below the column members 10a, 10b, 10c, and 10d. The first beam members 20a, 20b, 20c, and 20d are joined to the column members 10a, 10b, 10c, and 10d via the reinforcing members 240. The second beam members 30a, 30b, 30c, and 30d are joined to the column members 10a, 10b, 10c, and 10d via the reinforcing members 240.

[0119] The first beam member 20a connects to the column members 10a and 10b via reinforcing members 240, 240. The first beam member 20b connects to the column members 10a and 10b via reinforcing members 240, 240. The first beam member 20c connects to the column members 10c and 10d via reinforcing members 240, 240. The first beam member 20b connects to the column members 10c and 10d via reinforcing members 240, 240. The second beam member 30a connects to the column members 10a and 10c via reinforcing members 240, 240. The second beam member 30b connects to the column members 10a and 10c via reinforcing members 240, 240. The second beam member 30c connects to the column members 10b and 10d via reinforcing members 240, 240. The second beam member 30b connects the column members 10b and 10d via the reinforcing bodies 240, 240.

[0120] Hereinafter, the structure near the joint between the column member 10c, the first beam member 20c, and the second beam member 30a will be described in the same manner as in the first embodiment, and the description of the structure near other joints will be omitted.

[0121] Figure 25 is an enlarged perspective view of section XXV shown in Figure 24. Figure 26 is an enlarged side view of building unit 200 viewed from the direction of arrow XXVI shown in Figure 25. Figure 27 is a cross-sectional view along the line XXVII-XXVII shown in Figure 26. Figure 28 is a cross-sectional view along the line XXVIII-XXVIII shown in Figure 27.

[0122] As shown in Figures 25 to 28, the reinforcing body 240 comprises a body portion 241, an upper diaphragm 242 provided at the upper end of the body portion 241, and a lower diaphragm 243 provided at the lower end of the body portion 241. The cross-sectional shape of the body portion 241 is the same as that of the column member 10c. The body portion 241 is obtained by slicing the same material as the column member 10c into sections at a height corresponding to the web 21 of the first beam member 20c. The height of the web 31 of the second beam member 30a is the same as the height of the web 21 of the first beam member 20c, and the height of the body portion 241 is the height of the web 31 of the second beam member 30a.

[0123] The web 21 of the first beam member 20c extends to the body 241 and is joined to the side surface of the body 241. The web 31 of the second beam member 30a extends to the body 241 and is joined to the side surface of the body 241.

[0124] The upper diaphragm 242 extends laterally and closes the upper end opening of the body 241. The upper diaphragm 242 is joined to the upper flanges 22 and 23 of the first beam member 20c and the upper flanges 32 and 33 of the second beam member 30a.

[0125] The outer shape of the upper diaphragm 242 is larger than that of the body 241, and the upper diaphragm 242 protrudes from the side of the body 241. A notch 31b is formed at the upper end of the web 31 on the body 241 side. The notch 31b forms a gap at the corner between the body 241 and the upper diaphragm 242.

[0126] The lower diaphragm 243 extends laterally and closes the lower end opening of the body 241. The lower diaphragm 243 is joined to the lower flanges 24 and 25 of the first beam member 20c and the lower flanges 34 and 35 of the second beam member 30a. The lower diaphragm 243 is joined to the end face 11 of the column member 10c. Therefore, when horizontal forces (lateral forces) generated by earthquakes or wind are applied to the first beam member 20c and the second beam member 30a, the horizontal forces are transmitted and distributed across the entire cross-section of the column member 10c. Thus, local deformation of the column member 10c can be suppressed. This prevents the column member 10c from being crushed by the first beam member 20c and increases the rigidity of the building unit 200.

[0127] The outer shape of the lower diaphragm 243 is larger than that of the body 241, and the lower diaphragm 243 protrudes from the side of the body 241. A notch 31c is formed at the lower end of the web 31 on the body 241 side. The notch 31c forms a gap at the corner between the body 241 and the lower diaphragm 243.

[0128] Figure 29 is an enlarged perspective view showing the periphery of the connecting structure 1200 that connects the building units 200 shown in Figure 24. The connecting structure 1200 has a structure similar to the connecting structure 300 shown in Figure 11. Therefore, a detailed explanation of the connecting structure 1200 is omitted here. The connecting structure 1200 may have a structure similar to the connecting structure 400 (Figure 13), connecting structure 500 (Figure 14), connecting structure 600 (Figure 15), connecting structure 700 (Figure 16), connecting structure 800 (Figure 17), connecting structure 900 (Figure 19), connecting structure 1000 (Figure 21), and connecting structure 1100 (Figure 23).

[0129] The construction method for Building 1 according to this embodiment is substantially the same as the construction method for Building 1 according to the first embodiment, so its explanation is omitted here.

[0130] In the above embodiments, the reinforcing body 240 is provided to reinforce the column members 10a, 10b, 10c, and 10d. In the present invention, it is sufficient that the reinforcing body 240 is provided to reinforce at least one of the column members 10a, 10b, 10c, and 10d.

[0131] Although embodiments of the present invention have been described above, these embodiments only represent a part of the application examples of the present invention, and are not intended to limit the technical scope of the present invention to the specific configurations of the above embodiments.

[0132] In the above embodiment, the case where the first beam members 20a, 20b, 20c, 20d and the second beam members 30a, 30b, 30c, 30d are H-shaped steel. The first beam members 20a, 20b, 20c, 20d and the second beam members 30a, 30b, 30c, 30d are not limited to H-shaped steel.
