JP-A-64-1840

By the way, in the column-beam frame, it is possible to secure a large opening between the columns. As a result, it is possible to enhance the lighting and openness of the structure.

However, since there is a concern that the beam-column structure will increase the presence of the columns, other structures are required.

SUMMARY OF THE INVENTION An object of the present invention is to obtain a frame that can increase the aperture ratio in consideration of the above facts.

Each grid-like unit has a grid-like body in which a plurality of flat bars are joined in a grid-like manner. Thereby, the aperture ratio of the grid-like unit can be increased.

Here, the vertically arranged flat bars (hereinafter referred to as “vertical flat bars”) bear the roof load as an axial force in the grid. On the other hand, the horizontally arranged flat bars (hereinafter referred to as "horizontal flat bars") function as buckling suppressors that suppress buckling of the plurality of vertical flat bars. As a result, the roof load can be borne by the plurality of vertical flat bars while increasing the open area ratio of the grid-like unit.

A structure according to a second aspect is the structure according to the first aspect, wherein the plurality of lattice-like units are arranged vertically and horizontally, and a plurality of horizontal joints are respectively formed between the vertically adjacent lattice-like units. are displaced in the vertical direction, or a plurality of vertical joints respectively formed between the lattice-like units adjacent to each other in the left and right direction are displaced in the left and right direction.

According to the structure according to the second aspect, the plurality of grid-like units are arranged vertically and horizontally.

Here, for example, the corners of four grid-like units arranged vertically and horizontally are gathered in one place, and the vertical joints and horizontal joints formed between adjacent grid-like units are crossed in a cross shape, It is conceivable to join four grid-like units.

However, if the vertical joints and the horizontal joints cross each other in a cross shape, the vertical flat bars and the horizontal flat bars become discontinuous at the intersections, and the four grid-like units may become unstable in the out-of-plane direction. .

As a countermeasure, in the present invention, for example, a plurality of horizontal joints respectively formed between vertically adjacent lattice-like units are displaced in the vertical direction. In this case, the grid-like units are adjacent to each other in the left and right at the portions where the plurality of horizontal joints are displaced in the vertical direction. By joining the vertical flat bars of the grid-like units adjacent to each other in the left and right direction, the vertical flat bars can be made continuous in the vertical direction.

Further, for example, a plurality of vertical joints respectively formed between the grid-like units adjacent to each other on the left and right are arranged so as to be shifted in the left and right direction. In this case, the lattice-like units are vertically adjacent to each other in the portions where the plurality of vertical joints are displaced in the left-right direction. By joining the horizontal flat bars of the vertically adjacent grid-like units, the horizontal flat bars can be made continuous in the horizontal direction. Therefore, the four grid-like units can be stabilized in the out-of-plane direction.

According to the structure according to the third aspect, the roof has a sloped roof portion. Reinforcing beams are provided in the grid-like units connected along the sloped roof.

Here, a thrust force directed from the inclined roof toward the out-of-plane direction of the lattice-shaped unit acts on the lattice-shaped unit connected along the inclined roof. Therefore, there is a possibility that the grid-like unit is deformed in the out-of-plane direction.

As a countermeasure, in the present invention, as described above, reinforcing beams are provided in the grid-like units connected along the sloped roof. As a result, the out-of-plane deformation of the grid-like unit due to the thrust force of the sloping roof portion is suppressed.

According to the structure of the fourth aspect, the grid-like unit has shear force resistance members provided on the grid-like body. This shear force resistance member resists the shear force acting on the grid during an earthquake, thereby suppressing the shear deformation of the grid. Therefore, the seismic performance of the grid-like unit is improved.

A structure according to a fifth aspect is the structure according to any one of the first aspect to the fourth aspect, wherein the shear force resistance members are formed of flat bars, and braces are provided obliquely on the grid-like body. including.

According to the structure according to the fifth aspect, the shear force resistance members include braces obliquely provided on the grid. This makes it possible to efficiently suppress shear deformation of the grid during an earthquake.

Note that the joint structure between the wall grid-like unit 32 and the foundation 12 can be changed as appropriate. Further, the foundation 12 is not limited to a foundation slab, and may be a foundation beam or the like. Furthermore, the wall lattice-like unit 32 can be fixed not only to the foundation 12 but also to various structural bodies such as beams and slabs.

As shown in FIG. 3, the wall lattice-like units 32 adjacent in the width direction are arranged such that the vertical flat bars 42 on the outer periphery of each are opposed to each other and the horizontal flat bars 44 are continuous. there is Adjacent wall lattice-like units 32 are bolted via filler plates 60 in this manner.

(Action)
Next, the operation of this embodiment will be described.

As shown in FIG. 1 , the structure 10 according to this embodiment includes a roof 20 and outer walls 30 that support the roof 20 . The frame of the outer wall 30 is formed by joining a plurality of wall grid-like units 32 arranged in the width direction.

As shown in FIG. 3 , the wall lattice-like unit 32 has a lattice-like body 40 and braces 50 obliquely provided on the lattice-like body 40 . The lattice-like body 40 is formed by joining a plurality of vertical flat bars 42 and horizontal flat bars 44 to form a lattice. This lattice-like body 40 has a plurality of openings 46 defined by vertical flat bars 42 and horizontal flat bars 44 . Thereby, the aperture ratio of the wall grid-like unit 32 can be increased.

Here, the vertical flat bars 42 of the wall grid-like unit 32 bear the load of the roof 20 (roof load) as an axial force. On the other hand, the horizontal flat bars 44 function as buckling suppressors that suppress buckling of the plurality of vertical flat bars 42 . As a result, the load of the roof 20 (roof load) can be borne by the plurality of vertical flat bars 42 while increasing the open area ratio of the wall grid-like unit 32 .

In addition, braces 50 are provided on the lattice-like body 40 . This suppresses shear deformation of the lattice-like body 40 during an earthquake. Therefore, the earthquake resistance performance of the lattice-like wall unit 32 is improved.

Furthermore, brace 50 is formed by a flat bar. As a result, it is possible to improve the seismic performance of the wall lattice-like unit 32 while reducing the influence on the opening ratio of the lattice-like body 40 .

In this way, in the present embodiment, by forming the structure of the outer wall 30 with a plurality of lattice-like wall units 32, the aperture ratio of the outer wall 30 can be increased.

In addition, when the frame of the outer wall is formed of a column-beam frame, the presence of the columns and beams tends to be large, but the wall lattice-like unit 32 of the present embodiment is formed of flat bars. Therefore, the opening ratio of the outer wall 30 can be increased without increasing the presence of the members forming the frame of the outer wall 30, in other words, making the members forming the frame of the outer wall 30 inconspicuous. Therefore, in this embodiment, the transparent outer wall 30 can be formed.

Furthermore, the structure of the sloped roof portion 20A of the roof 20 is formed by roof lattice units 22, like the structure of the outer wall 30. As shown in FIG. Therefore, the opening ratio of the inclined roof portion 20A can be increased without increasing the presence of the members forming the frame of the inclined roof portion 20A.

Moreover, in the present embodiment, the exterior parts such as the roof 20 and the outer walls 30 are entirely formed of grid-like units (roof grid-like unit 22 and wall grid-like unit 32). As a result, a transparent structure 10 can be formed as a whole.

Also, the upper end of the wall grid unit 32 is connected to the lower end of the roof grid unit 22 . A reinforcing beam 70 is provided at the upper end of the lattice-like wall unit 32 .

Here, as shown in FIG. 7 , a thrust force S is exerted on the upper end of the wall lattice unit 32 from the lower end of the roof lattice unit 22 toward the out-of-plane direction of the wall lattice unit 32 . works. Therefore, there is a possibility that the wall grid-like unit 32 is deformed in the out-of-plane direction.

As a countermeasure against this, in the present embodiment, the reinforcing beams 70 are provided at the upper end portion of the wall grid-like unit 32 as described above. The reinforcing beams 70 impart out-of-plane rigidity to the wall grid-like unit 32 . Therefore, the out-of-plane deformation of the wall grid unit 32 due to the thrust force S of the roof grid unit 22 is suppressed.

In addition, by joining the reinforcing beams 70 to other wall grid units that intersect with the wall grid units 32 at the corners of the structure 10, or to the floor such as a slab provided inside the structure 10, Out-of-plane deformation of the wall lattice-like unit 32 can be further suppressed.

By the way, as shown in FIG. 3, horizontal flat bars 44 and braces 50 are welded to the vertical flat bars 42 on the outer periphery of the wall grid-like unit 32 . Therefore, the vertical flat bar 42 may be distorted by welding heat. In particular, since the vertical flat bar 42 is formed of a flat bar, it is likely to be distorted by welding heat.

Therefore, when the vertical flat bars 42 on the outer periphery of the wall lattice-like units 32 adjacent in the width direction are directly overlapped and bolted together, the vertical flat bars 42 do not adhere to each other due to the strain, and the vertical flat bars 42 do not adhere to each other. bond strength may decrease.

As a countermeasure, in the present embodiment, the vertical flat bars 42 on the outer peripheral portions of the lattice-like wall units 32 adjacent in the width direction are joined with the bolts 62 and the nuts 64 via the filler plates 60 . As a result, the vertical flat bars 42 can be joined by the bolts 62 and the nuts 64 in a state in which the vertical flat bars 42 are partially brought into close contact with each other via the filler plate 60 . Therefore, the joint strength between the vertical flat bars 42 can be ensured.

(Modification)
Next, a modification of the above embodiment will be described.

In the above embodiment, the plurality of wall grid units 32 are arranged in the width direction, but the plurality of wall grid units 32 may be arranged in the height direction.

Also, as in the modification shown in FIG. 8, the plurality of wall lattice-like units 32 may be arranged in the height direction and the width direction. Specifically, in the modification shown in FIG. 8, four wall grid units 32 are arranged vertically and horizontally.

8, illustration of the brace 50 is omitted. The vertical direction of the wall grid units 32 coincides with the height direction (arrow H direction) of the wall grid units 32, and the horizontal direction of the wall grid units 32 coincides with the direction of the wall grid units 32. It coincides with the width direction (direction of arrow W). In the following description, for convenience of explanation, the four wall grid units 32 arranged vertically and horizontally are referred to as a wall grid unit 32A, a wall grid unit 32B, a wall grid unit 32C, and a wall grid unit 32C. A grid-like unit 32D is assumed.

As shown in FIG. 8, the wall lattice unit 32A and the wall lattice unit 32B are arranged vertically (in the height direction) and joined by bolts 82 and nuts 84 via filler plates 80. ing. Horizontal joints 90X extending in the horizontal direction are formed between the wall lattice-like unit 32A and the wall lattice-like unit 32B. The filler plate 80 has the same configuration as the filler plate 60 described above.

The wall lattice-like unit 32C and the wall lattice-like unit 32D are arranged vertically (in the height direction) and joined to each other by bolts 82 and nuts 84 via filler plates 80 . A lateral joint 90X extending in the left-right direction is formed between the wall grid-like unit 32C and the wall grid-like unit 32D.

Here, the horizontal joints 90X between the wall lattice units 32A and 32B and the horizontal joints 90X between the wall lattice units 32C and 32D are arranged to be displaced in the vertical direction. More specifically, the horizontal joint 90X between the lattice-like wall units 32A and 32B is arranged above the horizontal joint 90X between the lattice-like wall units 32C and 32D.

As a result, the upper portion of the wall lattice-like unit 32B and the lower portion of the wall lattice-like unit 32C are arranged side by side. The vertical flat bars 42 on the outer peripheries of the laterally adjacent wall grid units 32B and 32C are joined by bolts 62 and nuts 64 via filler plates 60 .

Here, for example, as shown in FIG. 9, the corners of the four wall grid units 32A, 32B, 32C, and 32D arranged vertically and horizontally are gathered in one place, and the adjacent wall grid unit 32A is , 32B, 32C, and 32D in a state where the vertical joints 90Y and the horizontal joints 90X formed between the wall grid units 32A, 32B, 32C, and 32D cross each other in a criss-cross manner.

However, when the vertical joint 90Y and the horizontal joint 90X cross each other in a crisscross pattern, the vertical flat bar 42 and the horizontal flat bar 44 become discontinuous at the crossing portion, resulting in four wall grid units 32A, 32B, 32C, and 32D. can become unstable in the out-of-plane direction.

As a countermeasure, in this modified example, as shown in FIG. The ground 90X is displaced in the vertical direction.

As a result, as described above, the upper portion of the wall lattice-like unit 32B and the lower portion of the wall lattice-like unit 32C are arranged side by side. By joining the vertical flat bars 42 on the outer periphery of these wall grid units 32B and 32C with bolts 62 and nuts 64 via filler plates 60, the vertical flat bars of the wall grid units 32B and 32C are joined together. 42 are continuous in the vertical direction. Therefore, the four wall grid units 32A, 32B, 32C, and 32D can be stabilized in the out-of-plane direction.

In the modification shown in FIG. 8, the horizontal joint 90X between the lattice-like wall units 32A and 32B is arranged above the horizontal joint 90X between the lattice-like wall units 32C and 32D. Conversely, the horizontal joint 90X between the lattice-like wall units 32C and 32D may be arranged above the horizontal joint 90X between the lattice-like wall units 32A and 32B.

It is also possible to shift the vertical joint 90Y between the laterally adjacent wall lattice units 32A and 32C and the laterally adjacent vertical joint 90Y between the laterally adjacent wall lattice units 32B and 32D. For example, in FIG. 2, the vertical joints 90Y between the roof lattice-like units 22 adjacent to each other on the left and right and the vertical joints 90Y between the wall lattice-like units 32 adjacent to each other on the left and right are displaced in the left-right direction (direction of the arrow W). are placed. Thereby, an effect similar to that of the modification shown in FIG. 8 can be obtained.

Reference numeral 90X shown in FIG. 2 denotes a vertical joint between the roof lattice-like unit 22 and the wall lattice-like unit 32 that are vertically adjacent to each other.

Next, in the modification shown in FIG. 10, the vertical joint 90Y between the laterally adjacent wall grid-like units 32A and 32C and the vertical joint 90Y between the laterally adjacent wall grid-like units 32B and 32D are A through filler plate (through flat bar) 92 is disposed across. The vertical flat bars 42 on the outer peripheries of the laterally adjacent wall grid units 32A and 32C are bolted to each other via a through filler plate 86. As shown in FIG. Further, the vertical flat bars 42 on the outer periphery of the laterally adjacent wall lattice units 32B and 32D are bolted through filler plates 86. As shown in FIG.

As a result, the vertical flat bars 42 on the outer peripheries of the wall grid units 32A and 32C and the vertical flat bars 42 on the outer peripheries of the wall grid units 32B and 32D move vertically through the through filler plate 86. be consecutive. Therefore, the four wall grid units 32A, 32B, 32C, and 32D can be stabilized in the out-of-plane direction.

Although not shown, the through-filler plate has a horizontal joint 90X between the vertically adjacent wall lattice units 32A and 32B and a horizontal joint 90X between the vertically adjacent wall lattice units 32C and 32D. may be arranged over the

Next, in the above embodiment, the brace 50 as a shear force resistance member is provided on the grid-like body 40, but the above embodiment is not limited to this. The shear force resistance member may be, for example, a panel member or the like that is attached to the grid 40 and resists the shear force acting on the grid 40 .

Specifically, as shown in FIG. 11, panel members 94 are attached to the outer surfaces of the grid-like bodies 40 (see FIG. 3) of the roof grid-like unit and the wall grid-like unit (not shown). . The panel member 94 is formed of a metal plate or the like, and is attached to the outer surface of the grid-like body 40 by bolts, welding, or the like so as to transmit shear force.

Further, the panel member 94 is formed with a plurality of openings 96 through which sunlight, wind and rain can pass. This panel member 94 resists the shearing force acting on the lattice-like body 40 during an earthquake, thereby suppressing the shear deformation of the lattice-like body 40 . Therefore, the seismic performance of the lattice-like body 40 is improved. Further, by forming a plurality of openings 96 in the panel member 94, it is possible to secure lighting, ventilation, and the like. In addition, the shear force resistance member may be provided on the lattice-like body 40 as necessary, and can be omitted as appropriate.

Next, in the above embodiment, the roof 20 is a sloped roof, but the above embodiment is not limited to this. The shape of the roof can be changed as appropriate, and may be, for example, a flat roof.

In the above-described embodiment, the frames of the roof 20 and the outer wall 30 of the structure 10 are formed by grid-like units (the roof grid-like unit 22 and the wall grid-like unit 32). Not exclusively. In the structure 10, at least a part of the framework supporting the roof 20 can be formed by grid-like units.

In addition, although the structure 10 according to the above-described embodiment does not have columns or a beam-to-column structure, it is possible to have columns or a beam-to-column structure partially present in the structure.

Although one embodiment of the present invention has been described above, the present invention is not limited to such an embodiment, and one embodiment and various modifications may be used in combination as appropriate. It goes without saying that various aspects can be implemented without departing from the scope.
