Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, from the viewpoints of daylighting, openness, ventilation, design, etc., it is conceivable to form vertically long or horizontally long openings in the structure.

[0005] However, when vertically long or horizontally long openings are formed in the structure, the seismic performance may decrease.

[0006] An object of the present invention is to form vertically long or horizontally long openings in a structure while suppressing a decrease in seismic performance in consideration of the above facts.

Means for Solving the Problems

[0007] The structure according to claim 1 includes a first three-dimensional structure having an outer column-beam structure at one end side, a second three-dimensional structure having an inner column-beam structure arranged in the plane of the outer column-beam structure at one end side and adjacent to the first three-dimensional structure, and a connecting member that connects the outer column-beam structure and the inner column-beam structure.

[0008] According to the structure according to claim 1, the first three-dimensional structure has an outer column-beam structure at one end. This first three-dimensional structure is adjacent to the second three-dimensional structure. The second three-dimensional structure has an inner column-beam structure at one end.

[0009] Here, the inner column-beam structure is arranged within the plane of the outer column-beam structure. Thereby, a vertically long or horizontally long opening can be formed along the outer periphery of the inner column-beam structure between the outer column-beam structure and the inner column-beam structure. Therefore, the lighting property, openness, ventilation property, design property, etc. of the structure can be enhanced.

[0010] Also, for example, by configuring the first three-dimensional structure and the second three-dimensional structure to be able to independently bear seismic forces, the outer column-beam structure and the inner column-beam structure can be connected by a minimum necessary number of connecting members. Thereby, the lighting property, openness, ventilation property, and design property can be maximally enhanced. Further, the relative movement between the outer column-beam structure and the inner column-beam structure during an earthquake is suppressed by the connecting members. Therefore, since the destruction of the finishing materials due to the relative movement between the outer column-beam structure and the inner column-beam structure can be suppressed, the seismic performance of the structure is ensured.

[0011] Thus, in the present invention, while suppressing a decrease in seismic performance, a vertically long or horizontally long opening can be formed in the structure.

[0012] The structure according to claim 2 is the structure according to claim 1, wherein an opening is formed along the outer periphery of the inner column-beam structure within the plane of the outer column-beam structure, and the connecting member is a connecting beam that connects the columns of the outer column-beam structure and the inner column-beam structure that partition the opening.

[0013] According to the structure according to claim 2, an opening is formed along the outer periphery of the inner column-beam structure within the plane of the outer column-beam structure. Therefore, the lighting property, openness, ventilation property, design property, etc. of the structure can be enhanced.

[0014] Further, the connecting member is a connecting beam that connects columns of the outer column-beam framework and the inner column-beam framework that partition the opening. Thus, in the present invention, compared with the case where the connecting member is a connecting column that connects beams of the outer column-beam framework and the inner column-beam framework, a horizontally long opening can be formed within the plane of the outer column-beam framework.

[0015] The structure according to claim 3 is the structure according to claim 1 or claim 2, wherein the first three-dimensional framework has an opposing column-beam framework that opposes the outer column-beam framework, and a brace framework that connects columns of the outer column-beam framework and columns of the opposing column-beam framework.

[0016] According to the structure according to claim 3, the first three-dimensional framework has an opposing column-beam framework and a brace framework. The opposing column-beam framework opposes the outer column-beam framework. Columns of this opposing column-beam framework and columns of the outer column-beam framework are connected by the brace framework. By this brace framework, columns of the outer column-beam framework are reinforced.

[0017] By reinforcing the columns of the outer column-beam framework with the brace framework in this way, the cross-sectional area of the columns can be reduced. Thereby, for example, the columns of the outer column-beam framework can be housed within a wall, or the column shape of the columns can be eliminated. Therefore, the design property of the structure can be further enhanced.

Advantages of the Invention

[0018] As described above, according to the present invention, it is possible to form vertically long or horizontally long openings in the structure while suppressing a decrease in seismic performance.

Mode for Carrying Out the Invention

[0020] Hereinafter, an embodiment will be described with reference to the drawings.

[0021] In FIG. 1, a structure 10 according to this embodiment is shown. The arrow X direction appropriately shown in each figure indicates the longitudinal direction of the structure 10, and the arrow Y direction indicates the short-side direction of the structure 10.

[0022] The structure (building) 10 is, as an example, a three-dimensional (three-dimensional) zigzag type. That is, as shown in FIG. 2, in plan view (plan sectional view), one side surface side is formed in a zigzag shape, and as shown in FIG. 3, in side view (longitudinal sectional view) seen from the short-side direction (arrow Y direction), the roof surface side is formed in a zigzag shape.

[0023] (Space Frame Structure) The structure 10 includes a foundation 12, a plurality of space frame structures 20 arranged in the longitudinal direction of the structure 10, and a plurality of connecting beams 80 that connect adjacent space frame structures 20 to each other. The plurality of space frame structures 20 are, as an example, made of a steel frame structure and are erected on the foundation 12. Each space frame structure 20 has an outer column-beam frame structure 30, an inner column-beam frame structure 40, a pair of connecting column-beam frame structures 50, 60, and a roof frame structure 70.

[0024] Note that the three-dimensional structures 20 adjacent to each other in the longitudinal direction of the structure 10 are examples of the first three-dimensional structure and the second three-dimensional structure. Further, the connecting beam 80 is an example of a connecting member. Furthermore, the inner column-beam structure 40 is an example of an opposing column-beam structure. Also, the three-dimensional structure 20 is not limited to a steel structure, and may be a reinforced concrete structure, a steel-reinforced concrete structure, or the like.

[0025] (Outer column-beam structure) As shown in FIGS. 1 and 2, the outer column-beam structure 30 is arranged along the short side direction (arrow Y direction) of the structure 10 on one end side of the three-dimensional structure 20. The outer column-beam structure 30 is a ramen structure having a pair of columns 32, 34 and a beam 36. The pair of columns 32, 34 are arranged opposite to each other in the short side direction of the structure 10. The beam 36 is installed between the pair of columns 32, 34. The beam 36 is installed at the upper ends of the pair of columns 32, 34 and constitutes the roof beam of the roof structure 70 described later.

[0026] (Inner column-beam structure) The inner column-beam structure 40 is arranged along the short side direction of the structure 10 on the other end side of the three-dimensional structure 20. The inner column-beam structure 40 and the outer column-beam structure 30 are arranged opposite to each other in the longitudinal direction (arrow X direction) of the structure 10. Also, the inner column-beam structure 40 is made lower in height and shorter in span than the outer column-beam structure 30.

[0027] The inner column-beam structure 40 has a pair of columns 42, 44 and upper and lower beams 46, 48. The pair of columns 42, 44 are arranged opposite to each other in the short side direction of the structure 10. The pair of columns 42, 44 are made lower in height and shorter in span than the pair of columns 32, 34 of the outer column-beam structure 30. The upper and lower beams 46, 48 are installed between the pair of columns 42, 44.

[0028] The upper and lower beams 46, 48 are arranged at intervals in the vertical direction. The upper beam 46 is installed at the upper ends of the pair of columns 42, 44 and constitutes the roof beam of the roof structure 70. This upper beam 46 is arranged at a position lower than the beam 36 of the outer column-beam structure 30. On the other hand, the lower beam 48 is installed at the intermediate portion in the material axis direction of the pair of columns 42, 44.

[0029] (Connecting column-beam structure) As shown in FIG. 1, the pair of connecting column-beam structures 50, 60 connect the outer column-beam structure 30 and the inner column-beam structure 40. Among the pair of connecting column-beam structures 50, 60, one connecting column-beam structure 50 is arranged along the longitudinal direction of the structure 10 and connects one of the columns 32, 42 of the outer column-beam structure 30 and the inner column-beam structure 40.

[0030] One connecting column-beam structure 50 has a pair of columns 32, 42 and upper and lower connecting beams 56, 58. The pair of columns 32, 42 are arranged opposite to each other in the longitudinal direction of the structure 10. The upper and lower connecting beams 56, 58 are installed on the pair of columns 32, 42.

[0031] Note that one connecting column-beam structure 50 shares the column 32 with the outer column-beam structure 30 and shares the column 42 with the inner column-beam structure 40.

[0032] The upper and lower connecting beams 56, 58 are arranged at intervals in the vertical direction. The upper connecting beam 56 is installed at the upper part of the pair of columns 32, 42, and the lower connecting beam 58 is installed at the lower part of the pair of columns 32, 42.

[0033] Among the pair of connecting column-beam structures 50, 60, the other connecting column-beam structure 60 is, for example, a brace structure and connects the other columns 34, 44 of the outer column-beam structure 30 and the inner column-beam structure 40.

[0034] On the other hand, the other connecting column-beam structure 60 is inclined inwardly of the three-dimensional structure 20 from the column 34 of the outer column-beam structure 30 toward the column 44 of the inner column-beam structure 40 in plan view. In other words, the other connecting column-beam structure 60 is inclined outwardly of the three-dimensional structure 20 from the column 44 of the inner column-beam structure 40 toward the column 34 of the outer column-beam structure 30 in plan view.

[0035] As shown in FIGS. 1 and 3, the connecting column-beam structure 60 has a pair of columns 34, 44, upper and lower connecting beams 66, 68, and a pair of braces 69. The pair of columns 34, 44 are arranged offset in the lateral direction (arrow Y direction) of the structure 10 and face each other in a direction inclined with respect to the longitudinal direction (arrow X direction) of the structure 10. The upper and lower connecting beams 66, 68 are installed between the pair of columns 34, 44.

[0036] Note that the other connecting column-beam structure 60 shares the column 34 with the outer column-beam structure 30 and shares the column 44 with the inner column-beam structure 40.

[0037] The upper and lower connecting beams 66, 68 are arranged at intervals in the vertical direction. The upper connecting beam 66 is installed above the pair of columns 34, 44, and the lower connecting beam 68 is installed below the pair of columns 34, 44.

[0038] The pair of braces 69 are, for example, X-shaped braces and are provided in an X shape within the cross-section of the connecting column-beam structure 60. The pair of braces 69 enhance the rigidity of the connecting column-beam structure 60.

[0039] (Roof structure) The roof structure 70 constitutes the roof surface of the three-dimensional structure 20. Further, the roof structure 70 is inclined downward from the outer column-beam structure 30 toward the inner column-beam structure 40. The roof structure 70 is, for example, a brace structure and connects the outer column-beam structure 30 and the inner column-beam structure 40.

[0040] Specifically, the roof structure 70 has two beams 36, 46, two roof beams 72, 74, and a plurality of braces 76. The roof beam 72 is obliquely installed at the upper ends of the columns 32, 42, and the roof beam 74 is obliquely installed at the upper ends of the pair of columns 34, 44. Further, the four beams 36, 46 and the roof beams 72, 74 are connected in a rectangular shape in plan view, constituting a planar structure (roof surface).

[0041] Note that the roof structure 70 shares the beam 36 with the outer column-beam structure 30 and shares the beam 46 with the inner column-beam structure 40.

[0042] The plurality of braces 76 are horizontal braces and are obliquely provided within the plane of the roof structure 70. The rigidity of the roof structure 70 is enhanced by these braces 76.

[0043] Note that the plurality of braces 76 may be provided on the roof structure 70 as necessary and can be omitted as appropriate.

[0044] (Connecting beam) As shown in FIGS. 1 and 4, adjacent three-dimensional structures 20 are connected by a connecting beam 80. Specifically, the inner column-beam structure 40 of the adjacent other three-dimensional structure 20 is arranged within the plane of one adjacent outer column-beam structure 30. Thereby, an L-shaped opening 22 along the outer periphery of the inner column-beam structure 40 is formed within the plane of the outer column-beam structure 30.

[0045] Note that in this embodiment, the outer column-beam structure 30 and the inner column-beam structure 40 of adjacent three-dimensional structures 20 share the column 32. Further, the adjacent three-dimensional structures 20 are integrated via slabs (not shown) provided on the respective lower beams 48 and connecting beams 58, 68.

[0046] The opening 22 has a horizontally long opening 22A and a vertically long opening 22B. The horizontally long opening 22A is formed between the beams 36, 46 of the outer column-beam structure 30 and the inner column-beam structure 40. Further, the horizontally long opening 22A is a horizontally long opening extending between the pair of columns 32, 34 of the outer column-beam structure 30.

[0047] In addition, in this embodiment, the beams 36 and 46 of the outer column-beam structure 30 and the inner column-beam structure 40 are joined by a connecting column 82 that crosses the vertically long opening 22B. However, the connecting column 82 may be provided in the three-dimensional structure 20 as needed and can be omitted as appropriate.

[0048] As shown in FIG. 3, the horizontally long opening 22A faces the roof structure (roof surface) 70 of another adjacent three-dimensional structure 20. This horizontally long opening 22A enhances the daylighting property, openness, and ventilation property inside the structure 10, and also enhances the design property of the structure 10.

[0049] As shown in FIG. 4, the vertically long opening 22B is formed between the other columns 34 and 44 of the outer column-beam structure 30 and the inner column-beam structure 40. Further, the vertically long opening 22B is a vertically long opening that extends over the entire length of the other column 34 of the outer column-beam structure 30.

[0050] As shown in FIG. 2, the vertically long opening 22B faces the connecting column-beam structure 60 of another adjacent three-dimensional structure 20. This vertically long opening 22B enhances the daylighting property, openness, and ventilation property inside the structure 10, and also enhances the design property of the structure 10.

[0051] As shown in FIG. 4, the columns 34 and 44 of the outer column-beam structure 30 and the inner column-beam structure 40 that partition the vertically long opening 22B are connected by a plurality of connecting beams 80. The plurality of connecting beams 80 are provided so as to be continuous with the upper and lower beams 46 and 48 of the inner column-beam structure 40.

[0052] Note that the upper and lower beams 46 and 48 have the same configuration. Therefore, hereinafter, the configuration of the lower beam 48 will be described, and the description of the configuration of the upper beam 46 will be omitted.

[0053] As shown in FIGS. 5 and 6, the beam 48 below the inner column-beam structure 40 is formed of, for example, H-shaped steel. This beam 48 has a pair of flange portions 48A facing each other in the vertical direction and a web portion 48B connecting the pair of flange portions 48A.

[0054] At the end of the beam 48 on the column 34 side, a pair of horizontal ribs 48C and a pair of cover plates 48D are provided. The pair of horizontal ribs 48C are arranged along the material axis direction of the beam 48 and are provided in a rib shape on the web portion 48B of the beam 48. The pair of horizontal ribs 48C face the pair of flange portions 48A of the beam 48 in the vertical direction.

[0055] The pair of horizontal ribs 48C and the lower flange portion 48A are connected by a pair of cover plates 48D. The pair of cover plates 48D are arranged facing each other with the web portion 48B of the beam 48 interposed therebetween. The end of this beam 48 is joined to the joint portion 44S of the column 44.

[0056] In the joint portion 44S of the column 44, a pair of diaphragms 44A to which the pair of flange portions 48A of the beam 48 are joined are provided. Also, in the joint portion 44S of the column 44, a pair of stiffeners 44C continuous with the pair of horizontal ribs 48C of the beam 48 are provided. Further, in the joint portion 44S of the column 44, a pair of stiffeners 44B continuous with the web portion 80B of the connecting beam 80 are provided.

[0057] Note that the beam 48 is not limited to H-shaped steel, and other shaped steels or the like may be used. Also, the reinforcing structure at the end of the beam 48 is not limited to the above-described one and can be appropriately changed.

[0058] The connecting beam 80 has a lower beam height than the beam 48 below the inner column-beam structure 40. Also, the connecting beam 80 is formed of, for example, H-shaped steel with the strong axis direction being the horizontal direction. In other words, the connecting beam 80 is formed of, for example, horizontally used H-shaped steel.

[0059] The connecting beam 80 has a pair of flange portions 80A facing each other in the longitudinal direction of the structure 10 and a web portion 80B connecting the pair of flange portions 80A. One end portion of this connecting beam 80 is joined to the joint portion 44S of the column 44 of the inner column-beam framework 40. Further, the other end portion of the connecting beam 80 is joined to the joint portion 34S of the column 34 of the outer column-beam framework 30.

[0060] In the joint portion 34S of the column 34, a pair of stiffeners 34B continuous with the web portion 80B of the connecting beam 80 are provided.

[0061] Note that the connecting beam 80 is not limited to a horizontally used H-shaped steel, and may be formed of, for example, a vertically used H-shaped steel or other shaped steels. Further, the reinforcement structure of the joint portions 34S and 44S of the columns 34 and 44 is not limited to the above-described one and can be appropriately changed.

[0062] (Function) Next, the function of this embodiment will be described.

[0063] As shown in FIGS. 1 and 2, according to this embodiment, the structure 10 includes a plurality of three-dimensional frameworks 20 arranged in the longitudinal direction of the structure 10. Each three-dimensional framework 20 has an outer column-beam framework 30 and an inner column-beam framework 40 facing each other in the longitudinal direction of the structure 10. The outer column-beam framework 30 is disposed on one end side of the three-dimensional framework 20, and the inner column-beam framework 40 is disposed on the other end side of the three-dimensional framework 20.

[0064] Here, as shown in FIG. 4, within the plane of the outer column-beam framework 30 of the three-dimensional framework 20, the inner column-beam frameworks 40 of other adjacent three-dimensional frameworks 20 are arranged. Thereby, an L-shaped opening 22 along the outer periphery of the inner column-beam framework 40 is formed between the outer column-beam framework 30 and the inner column-beam framework 40.

[0065] More specifically, a horizontally long opening 22A is formed between the beams 36 and 46 of the outer column-beam structure 30 and the inner column-beam structure 40, and a vertically long opening 22B is formed between the columns 34 and 44 of the outer column-beam structure 30 and the inner column-beam structure 40. This opening 22 can enhance the lighting property, openness, ventilation property, design property, etc. of the structure 10.

[0066] Further, the columns 34 and 44 of the outer column-beam structure 30 and the inner column-beam structure 40 are connected by a connecting beam 80. Thereby, the relative movement between the outer column-beam structure 30 and the inner column-beam structure 40 during an earthquake is suppressed. Therefore, for example, since the destruction of the finishing material due to the relative movement between the outer column-beam structure 30 and the inner column-beam structure 40 is suppressed, the decrease in the seismic performance of the structure 10 is suppressed.

[0067] Also, for example, by configuring adjacent three-dimensional structures 20 to be capable of independently bearing seismic forces, the outer column-beam structure 30 and the inner column-beam structure 40 can be connected by a minimum necessary connecting beam 80. Thereby, the lighting property, openness, ventilation property, and design property can be enhanced to the maximum extent.

[0068] Thus, in this embodiment, while suppressing the decrease in seismic performance, the horizontally long opening 22A and the vertically long opening 22B can be formed in the structure 10.

[0069] Further, the connecting beam 80 connects the columns 34 and 44 of the outer column-beam structure 30 and the inner column-beam structure 40 that partition the vertically long opening 22B. Thereby, in this embodiment, compared with the case where the beams 36 and 46 of the outer column-beam structure 30 and the inner column-beam structure 40 are connected by a connecting column, a horizontally long opening 22A can be formed within the cross-section of the outer column-beam structure 30.

[0070] Here, FIG. 7 shows a structure 100 according to a comparative example. In this structure 100, the spans of the outer column-beam framework 30 and the inner column-beam framework 40 are the same, and one column 32, 34, 42 and the other column 34, 44 are shared. Further, in the structure 100 according to the comparative example, a horizontally long opening 22A is formed between the beams 36, 46 of the outer column-beam framework 30 and the inner column-beam framework 40. Furthermore, vertically long openings 22B are formed outside the column 34 of the outer column-beam framework 30 by the projecting beams 102, 104 that project outward from the column 34 of the outer column-beam framework 30.

[0071] In the structure 100 according to the comparative example, the horizontally long opening 22A and the vertically long openings 22B are separated by the column 34 of the outer column-beam framework 30. In other words, the column 34 of the outer column-beam framework 30 crosses the horizontally long opening 22A. Also, in the structure 100 according to the comparative example, the cross-sectional area of the column 34 of the outer column-beam framework 30 is large. As a result, in the structure 100 according to the comparative example, the width W0 of the horizontally long opening 22A is narrow.

[0072] On the other hand, in the structure 10 according to the present embodiment, as described above, the connecting beam 80 connects the columns 34, 44 of the outer column-beam framework 30 and the inner column-beam framework 40 that partition the vertically long opening 22B. Thereby, in the structure 10 according to the present embodiment, the width W1 (see FIG. 4) of the horizontally long opening 22A can be made wider than that of the structure 100 according to the comparative example.

[0073] Also, as shown in FIG. 2, in the present embodiment, the columns 34, 44 of the outer column-beam framework 30 and the inner column-beam framework 40 are arranged side by side in the short side direction (arrow Y direction) of the structure 10. Thereby, in the structure 10 according to the present embodiment, the cross-sectional area of the column 34 of the outer column-beam framework 30 can be made smaller than that of the column 34 of the structure 100 according to the comparative example. Therefore, the width W1 (see FIG. 4) of the horizontally long opening 22A can be further widened.

[0074] Furthermore, in the present embodiment, in each three-dimensional structure 20, the outer column-beam structure 30 and the inner column-beam structure 40 are arranged to face each other in the longitudinal direction of the structure 10. And the column 34 of the outer column-beam structure 30 and the column 44 of the inner column-beam structure 40 are connected by a connection column-beam structure 60 that is a brace structure. By this connection column-beam structure 60, the column 34 of the outer column-beam structure 30 is reinforced.

[0075] By reinforcing the column 34 of the outer column-beam structure 30 with the connection column-beam structure 60 that is a brace structure in this way, the cross-sectional area of the column 34 can be further reduced. Thereby, for example, the column 34 of the outer column-beam structure 30 can be housed in the wall or the column shape of the column 34 can be eliminated. Therefore, the design property of the structure 10 can be further enhanced.

[0076] Furthermore, the connection column-beam structure 60 is inclined with respect to the longitudinal direction of the structure 10 in plan view. More specifically, the connection column-beam structure 60 is inclined inward of the three-dimensional structure 20 from the column 34 of the outer column-beam structure 30 toward the column 44 of the inner column-beam structure 40 in plan view. Thereby, while securing the vertically long opening 22B, the design property of the structure 10 can be enhanced.

[0077] Furthermore, in the present embodiment, by arranging a plurality of three-dimensional structures 20, openings 22 can be formed in each three-dimensional structure 20. Therefore, the constructability of the structure 10 is improved.

[0078] (Modification example) Next, a modification example of the above embodiment will be described.

[0079] As shown in FIG. 2, in the above embodiment, in plan view, the connection column-beam structure 60 is inclined with respect to the longitudinal direction of the structure 10. However, for example, as in the modification example shown in FIG. 8, the connection column-beam structure 60 may be arranged along the longitudinal direction of the structure 10. Also in this case, a vertically long opening 22B can be secured in the columns 34 and 44 of the outer column-beam structure 30 and the inner column-beam structure 40.

[0080] In the above-described embodiment, the roof structure 70 is inclined in a side view seen from the short side direction (arrow Y direction) of the structure 10. However, the roof structure 70 may be horizontal, for example. Even in this case, a horizontally long opening 22A can be secured between the beams 36 and 46 of the outer column-beam structure 30 and the inner column-beam structure 40.

[0081] In the above-described embodiment, the connecting column-beam structure 60 is a brace structure. However, the connecting column-beam structure 60 may be provided with, for example, a seismic wall or the like as a seismic element, not limited to the brace 69. Further, the connecting column-beam structure 60 may be a column-beam structure having no seismic elements such as the brace 69 or the seismic wall.

[0082] In the above-described embodiment, the connecting member is the connecting beam 80. However, the connecting member is not limited to the connecting beam 80, and may be, for example, a connecting column that connects the beams 36 and 46 of the outer column-beam structure 30 and the inner column-beam structure 40.

[0083] In the above-described embodiment, the outer column-beam structure 30 and the inner column-beam structure 40 share one column 32, 42. However, the outer column-beam structure 30 and the inner column-beam structure 40 may not share one column 32, 42, and the columns 32, 42 may be provided separately. In this case, a C-shaped opening along the outer periphery of the inner column-beam structure 40 is formed within the configuration plane of the outer column-beam structure 30. Further, when the columns 32, 42 are provided separately, the seismic performance of the three-dimensional structure 20 can be enhanced by connecting these columns 32, 42 with a connecting beam or the like.

[0084] As described above, one embodiment of the present invention has been described. However, the present invention is not limited to such an embodiment, and one embodiment and various modifications may be used in appropriate combination, and it goes without saying that the present invention can be implemented in various modes without departing from the gist of the present invention.
