Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, when horizontally long holes are formed in the corrugated steel plate, there is a possibility that the peripheral portion of the horizontally long holes in the corrugated steel plate may be damaged along with the shear deformation of the corrugated steel plate.

[0006] In consideration of the above fact, an object of the present invention is to suppress the peripheral portion of the horizontally long holes in the corrugated steel plate from being damaged along with the shear deformation of the corrugated steel plate.

Means for Solving the Problems

[0007] Regarding the first aspectThe seismic wall comprises a corrugated steel plate attached to a frame, a stiffening surface material facing the corrugated steel plate, a central joining member inserted into a circular hole formed in the vertical center of the corrugated steel plate to join the corrugated steel plate and the stiffening surface material, and a plurality of connecting members inserted into horizontally elongated holes formed in the upper and lower parts of the corrugated steel plate, respectively, to connect the corrugated steel plate and the stiffening surface material so that they can move relative to each other in the lateral width direction of the corrugated steel plate.

[0008] First aspect In the seismic wall described herein, corrugated steel plates are attached to the frame. Stiffening panels are placed opposite these corrugated steel plates. A circular hole is formed in the center of the corrugated steel plate in the vertical direction. The corrugated steel plate and the stiffening panel are joined by a central connecting member inserted into this circular hole.

[0009] Furthermore, elongated horizontal holes are formed in the upper and lower parts of the corrugated steel plate. Multiple connecting members are inserted into these horizontal holes, thereby connecting the corrugated steel plate and the stiffening surface material so that they can move relative to each other in the lateral direction of the corrugated steel plate. Because the out-of-plane deformation of the corrugated steel plate is restricted by this stiffening surface material, buckling of the corrugated steel plate during an earthquake is suppressed.

[0010] In this configuration, when the corrugated steel plate undergoes shear deformation during an earthquake, the connecting members move along the elongated holes formed in the upper and lower parts of the corrugated steel plate. This suppresses interference between the connecting members and the periphery of the elongated holes, thereby preventing damage to the stiffening surface material.

[0011] On the other hand, the central joint member is inserted into a circular hole formed in the center of the corrugated steel plate in the vertical direction. As a result, when the center of the corrugated steel plate in the vertical direction moves in the horizontal direction due to shear deformation of the corrugated steel plate, the stiffening surface material moves in the horizontal direction of the corrugated steel plate together with the central joint member.

[0012] As a result, the relative movement in the lateral direction between the upper and lower parts of the corrugated steel plate and the stiffening surface material is reduced, making it possible to shorten the required length of the elongated holes formed in the upper and lower parts of the corrugated steel plate, respectively.

[0013] Regarding the second aspect The seismic wall is Regarding the first aspect In the seismic wall, a reinforcing member provided at a peripheral portion of the horizontally long hole in the corrugated steel plate is provided.

[0014] Second aspect According to the seismic wall according to [description], a reinforcing member is provided at a peripheral portion of the horizontally long hole in the corrugated steel plate. Thereby, damage to the peripheral portion of the horizontally long hole in the corrugated steel plate is suppressed along with the shear deformation of the corrugated steel plate.

[0015] Regarding the third aspect The seismic wall is First aspect or Regarding the second aspect In the seismic wall, the stiffening facing material is a wooden facing material.

[0016] Third aspect According to the seismic wall according to [description], the stiffening facing material is a wooden facing material. By covering the surface of the corrugated steel plate with this wooden facing material, the design property of the seismic wall is improved.

Effect of the Invention

[0017] As described above, according to the present invention, it is possible to suppress damage to the peripheral portion of the horizontally long hole in the corrugated steel plate along with the shear deformation of the corrugated steel plate.

Mode for Carrying Out the Invention

[0019] Hereinafter, a seismic wall according to an embodiment will be described while referring to the drawings.

[0020] In FIG. 1, a seismic wall 20 according to this embodiment is shown. The seismic wall 20 has a corrugated steel plate 30 and a pair of wooden face materials 80X and 80Y. The corrugated steel plate 30 is attached to the frame 10.

[0021] Note that the arrow H shown in each figure indicates the vertical direction (height direction) of the seismic wall 20, and the arrow W indicates the lateral width direction of the seismic wall 20. Also, the arrow T indicates the out-of-plane direction of the seismic wall 20 (corrugated steel plate 30).

[0022] (Frame) The frame 10 is a ramen frame having a pair of columns 12 and upper and lower beams 14 installed on the pair of columns 12. The pair of columns 12 are steel columns formed of square steel pipes and are erected at intervals. Also, the upper and lower beams 14 are steel beams formed of H-shaped steel and are installed on the pair of columns 12 at intervals in the vertical direction.

[0023] Note that the pair of columns 12 and the upper and lower beams 14 are not limited to steel structures, and may be reinforced concrete structures, steel-reinforced concrete structures, or the like.

[0024] (Corrugated Steel Plate) As shown in Figure 2, the cross-sectional (longitudinal) shape of the corrugated steel plate 30 is corrugated. Also, as shown in Figure 3, the corrugated steel plate 30 is placed inside the frame 10 with its folds facing sideways. A pair of vertical flanges 32 and a pair of horizontal flanges 34 are provided on the outer periphery of the corrugated steel plate 30. The pair of vertical flanges 32 and the pair of horizontal flanges 34 are joined together in a frame-like manner, surrounding the corrugated steel plate 30.

[0025] A pair of vertical flanges 32 are provided along the left and right ends of the corrugated steel plate 30 and are joined to these ends by welding or other means. These pair of vertical flanges 32 are each joined to a pair of columns 12 by welding or bolts (not shown).

[0026] A pair of horizontal flanges 34 are provided along the upper and lower ends of the corrugated steel plate 30 and are joined to these ends by welding or other means. Each of these horizontal flanges 34 is provided with a connecting plate 36. The connecting plates 36 are joined to connecting plates 38 provided on the upper and lower beams 14 by bolts, welding or other means.

[0027] (Wood-based paneling) As shown in Figure 2, the pair of wood panels 80X and 80Y are positioned on both sides of the corrugated steel plate 30 in the out-of-plane direction (direction of arrow T). The pair of wood panels 80X and 80Y are also placed on the lower horizontal flange 34 of the corrugated steel plate 30 via spacers 16. The spacers 16 may be provided as needed and can be omitted as appropriate.

[0028] A pair of wood panels 80X and 80Y are formed from CLT (Cross Laminated Timber) and face each other with a corrugated steel plate 30 in between. Each wood panel 80X and 80Y is formed in a rectangular shape when viewed from the out-of-plane direction and is slightly smaller than the corrugated steel plate 30. The size of the corrugated steel plate 30 can be changed as needed.

[0029] Furthermore, the pair of wood panels 80X and 80Y are not limited to CLT, but may also be formed from materials such as LVL (Laminated Veneer Lumber), glued laminated timber, or plywood. Also, the wood panels 80X and 80Y are an example of a stiffening panel.

[0030] As shown in Figure 4, a pair of wood panels 80X and 80Y are overlapped on both sides of the corrugated steel plate 30 and connected by multiple connecting bolts 52. The upper parts of the pair of wood panels 80X and 80Y and the upper parts of the corrugated steel plate 30 are connected so as to be able to move relative to each other in the lateral direction of the corrugated steel plate 30. In addition, the lower parts of the pair of wood panels 80X and 80Y and the lower parts of the corrugated steel plate 30 are connected so as to be able to move relative to each other in the lateral direction of the corrugated steel plate 30.

[0031] Furthermore, the upper part of the corrugated steel plate 30 refers to the portion above the central part (central valley 42M) in the vertical direction of the corrugated steel plate 30, which will be described later, and the lower part of the corrugated steel plate 30 refers to the portion below the said central part (central valley 42M).

[0032] Furthermore, the connection structure between the upper parts of the corrugated steel plate 30 and the pair of wood paneling materials 80X and 80Y is the same as the connection structure between the lower parts of the corrugated steel plate 30 and the pair of wood paneling materials 80X and 80Y. Therefore, the connection structure between the upper parts of the corrugated steel plate 30 and the pair of wood paneling materials 80X and 80Y will be described below, and the explanation of the connection structure between the lower parts of the corrugated steel plate 30 and the pair of wood paneling materials 80X and 80Y will be omitted.

[0033] As shown in Figure 4, the corrugated steel plate 30 has a corrugated shape in which multiple peaks 40 and valleys 42 alternately repeat when viewed in a longitudinal section. The multiple peaks 40 have top surfaces 40A that extend in the vertical direction. The inner surface 80S of one of the wood-based surface materials 80X is superimposed on these top surfaces 40A.

[0034] Multiple valleys 42 have bottom surfaces 42A that extend in the vertical direction. The inner surface 80S of the other wood panel 80Y is superimposed on these bottom surfaces 42A. Adjacent top surfaces 40A and bottom surfaces 42A are connected via slopes 44. The slopes 44 are inclined with respect to the top surfaces 40A and bottom surfaces 42A. Adjacent peaks 40 and valleys 42 share a slope 44.

[0035] The upper parts of the corrugated steel plate 30 and one of the wood-based panel materials 80X are connected as follows. As shown in Figures 3 and 6, two horizontally elongated holes 50 are formed in the top surface 40A of each peak 40 on the upper part of the corrugated steel plate 30. The two horizontally elongated holes 50 are spaced apart in the width direction of the corrugated steel plate 30. Each horizontally elongated hole 50 is a through hole that penetrates the top surface 40A in the thickness direction.

[0036] The number and arrangement of the horizontally elongated holes 50 can be changed as needed.

[0037] The elongated holes 50 are elongated holes (slot holes) that extend in the width direction of the corrugated steel plate 30. In addition, reinforcing plates 70 are provided around the elongated holes 50. The reinforcing plates 70 are made of steel plate or the like and are attached to the back surface of the top surface 40A (the surface opposite to the wood surface material 80X).

[0038] The reinforcing plate 70 has elongated holes 72 formed in it. The elongated holes 72 are the same shape and size as the elongated holes 50. The reinforcing plate 70 is joined to the back surface of the top surface portion 40A of the ridge portion 40 by welding or the like, with the elongated holes 72 and 50 aligned.

[0039] As shown in Figures 4 and 5, connecting bolts 52 are inserted into the elongated holes 50 and 72 of the top surface 40A and the reinforcing plate 70 via washers 54 from the other side of the wood panel 80Y. As shown in Figure 6, the connecting bolts 52 are movable along the elongated holes 50 and 72 in the lateral width direction of the corrugated steel plate 30.

[0040] Note that the connecting bolt 52 is an example of a connecting member.

[0041] As shown in Figures 4 and 5, the connecting bolts 52 inserted into the elongated holes 50 and 72 of the top surface 40A and the reinforcing plate 70 are screwed into one end of a lag screw bolt 82 provided on the upper part of one of the wood panels 80X. The lag screw bolt 82 is screwed into a pilot hole (not shown) formed in the inner surface 80S of one of the wood panels 80X.

[0042] The lag screw bolt 82 is screwed into the wood panel 80X such that one end does not protrude from the inner surface 80S of the wood panel 80X. A bolt hole (not shown) is formed in one end of the lag screw bolt 82. A connecting bolt 52 is screwed into this bolt hole through a horizontally elongated hole 50 formed in the top surface 40A of the ridge portion 40.

[0043] As a result, the inner surface 80S of one of the wood panels 80X is superimposed on (in contact with) the top surface 40A of the peak portion 40, and the upper parts of the wood panel 80X and the corrugated steel plate 30 are connected so that they can move relative to each other in the lateral direction of the corrugated steel plate 30.

[0044] Furthermore, the reinforcing plate 70 may be attached not only to the back surface of the top surface 40A of the ridge portion 40, but also to the surface of the top surface 40A of the ridge portion 40. In this case, the inner surface 80S of one of the wood surface materials 80X is superimposed on the surface of the top surface 40A of the ridge portion 40 via the reinforcing plate 70. Also, the reinforcing plate 70 may be provided only as needed and can be omitted as appropriate.

[0045] Next, the upper parts of the other wood panel 80Y and the corrugated steel plate 30 are connected as follows. As shown in Figures 3 and 6, two horizontally elongated holes 50 are formed in the bottom surface 42A of each valley 42 on the upper part of the corrugated steel plate 30. The number and arrangement of the horizontally elongated holes 50 can be changed as appropriate.

[0046] Furthermore, a reinforcing plate 70 is provided around the elongated hole 50. The reinforcing plate 70 is joined by welding or the like, overlapping the back surface (the side opposite to the wood panel 80Y) of the bottom surface 42A of the valley 42, so that the elongated hole 72 and the elongated hole 50 are aligned.

[0047] As shown in Figures 4 and 5, connecting bolts 52 are inserted from one side of the wood panel 80X into the elongated holes 50 and 72 of the bottom portion 42A and the reinforcing plate 70, respectively. As shown in Figure 6, the connecting bolts 52 are movable along the elongated holes 50 and 72 in the lateral width direction of the corrugated steel plate 30.

[0048] In addition, in one of the wooden panel members 80X, working holes 84 are formed in the portion opposite to the elongated hole 50 in the valley portion 42. Connecting bolts 52 can be inserted into the elongated hole 50 in the bottom portion 42A through these working holes 84. The working holes 84 are also closed, for example, with wooden plugs 86. The wooden plugs 86 are optional. Furthermore, the working holes 84 are not limited to a circular shape; they may also be elongated.

[0049] As shown in Figures 4 and 5, the connecting bolts 52 inserted into the horizontally elongated holes 50 and 72 of the bottom portion 42A and the reinforcing plate 70 are screwed into one end of a lag screw bolt 82 provided on the upper part of the other wood panel 80Y. As a result, the upper parts of the other wood panel 80Y and the corrugated steel plate 30 are connected so that they can move relative to each other in the lateral direction of the corrugated steel plate 30, with the inner surface 80S of the other wood panel 80Y overlapping (in contact with) the surface of the bottom portion 42A of the valley portion 42.

[0050] Furthermore, the reinforcing plate 70 may be attached not only to the back surface of the bottom surface 42A of the valley section 42, but also to the surface of the bottom surface 42A of the valley section 42. In this case, the inner surface 80S of the other wood panel 80Y is superimposed on the surface of the bottom surface 42A of the valley section 42 via the reinforcing plate 70. In this case, a spacer of the same thickness as the reinforcing plate 70 may also be provided on the surface of the bottom surface 42A of the central valley section 42M, which will be described later. Also, the reinforcing plate 70 may be provided only as needed and can be omitted as appropriate.

[0051] Here, the vertical center of the corrugated steel plate 30 and the vertical center of the other wood-based panel material 80Y are joined (fixed) by a plurality of joining bolts 62. Specifically, as shown in Figures 3 and 6, two circular holes 60 are formed in the bottom surface 42A of the valley (hereinafter referred to as the "central valley 42M") located in the vertical center of the corrugated steel plate 30. The two circular holes 60 are spaced apart in the lateral direction of the corrugated steel plate 30.

[0052] The vertical center of the corrugated steel plate 30 refers, for example, to the central part when the corrugated steel plate 30 is divided into five equal parts vertically. This vertical center of the corrugated steel plate 30 may be a peak 40 or a valley 42M. The number and arrangement of the circular holes 60 can also be changed as appropriate.

[0053] Each circular hole 60 is a circular through-hole that penetrates the bottom surface 42A of the central valley 42M in the thickness direction. Furthermore, each circular hole 60 is located in the center of the corrugated steel plate 30 in the vertical direction. As shown in Figures 4 and 5, a connecting bolt 62 is inserted into the circular hole 60 from one side of the wood panel 80X via a washer 64. The connecting bolt 62 is an example of a central connecting member.

[0054] The joining bolt 62 inserted into the round hole 60 is screwed into one end of a lag screw bolt 82 provided in the vertical center of the other wood panel 80Y. As a result, the vertical centers of the other wood panel 80Y and the corrugated steel plate 30 are joined (fixed) together, with the inner surface 80S of the other wood panel 80Y overlapping (in contact) with the bottom surface 42A of the central valley 42M.

[0055] Furthermore, in one of the wood panel materials 80X, work holes 84 are formed in the area opposite to the round hole 60 in the central valley section 42M. Connecting bolts 62 can be inserted into the round hole 60 in the central valley section 42M through these work holes 84.

[0056] (action) Next, the operation of this embodiment will be described.

[0057] As shown in Figure 2, according to this embodiment, a corrugated steel plate 30 is attached to the frame 10. A pair of wooden facing members 80X and 80Y are arranged on both sides of the corrugated steel plate 30 in the out-of-plane direction. The pair of wooden facing members 80X and 80Y are arranged opposite the corrugated steel plate 30.

[0058] As shown in Figure 4, a circular hole 60 is formed in the center of the corrugated steel plate 30 in the vertical direction. Specifically, the circular hole 60 is formed in the bottom surface 42A of the central valley 42M located in the center of the corrugated steel plate 30. The central parts of the corrugated steel plate 30 and the other wood panel 80Y are joined (fixed) together by joining bolts 62 inserted into this circular hole 60.

[0059] Furthermore, multiple elongated holes 50 are formed in the upper part of the corrugated steel plate 30. Specifically, elongated holes 50 are formed in the top surface 40A of the peaks 40 and the bottom surface 42A of the valleys 42 in the upper part of the corrugated steel plate 30. By screwing connecting bolts 52 inserted into these elongated holes 50 into lag screw bolts 82 provided on a pair of wood paneling 80X, 80Y, the upper parts of the corrugated steel plate 30 and the pair of wood paneling 80X, 80Y are connected so that they can move relative to each other in the lateral width direction of the corrugated steel plate 30.

[0060] Similarly, multiple elongated holes 50 are formed in the lower part of the corrugated steel plate 30. Specifically, in the lower part of the corrugated steel plate 30, elongated holes 50 are formed in the top surface 40A of the peaks 40 and the bottom surface 42A of the valleys 42, respectively. By screwing connecting bolts 52 inserted into these elongated holes 50 into lag screw bolts 82 provided on a pair of wood paneling 80X, 80Y, the lower parts of the corrugated steel plate 30 and the pair of wood paneling 80X, 80Y are connected so that they can move relative to each other in the lateral width direction of the corrugated steel plate 30.

[0061] By attaching a pair of wooden panels 80X and 80Y to the corrugated steel plate 30 in this manner, the out-of-plane deformation of the corrugated steel plate 30 is restricted. Therefore, buckling of the corrugated steel plate 30 during an earthquake is suppressed.

[0062] Further, during an earthquake, when the corrugated steel plate 30 undergoes shear deformation, the connecting bolts 52 move along the horizontally elongated holes 50 formed in the upper and lower portions of the corrugated steel plate 30, respectively. Thereby, interference between the connecting bolts 52 and the peripheral portions of the horizontally elongated holes 50 is suppressed, so that damage to the pair of wood surface materials 80X and 80Y is suppressed.

[0063] Here, FIG. 7(B) shows a seismic wall 100 according to a comparative example. In the seismic wall 100 according to the comparative example, the central portions of the corrugated steel plate 30 and the other wood surface material 80Y are not joined. In this case, the other wood surface material 80Y does not follow the shear deformation of the corrugated steel plate 30, and the relative movement amount D1 between the upper portions of the corrugated steel plate 30 and the other wood surface material 80Y increases. Therefore, since the required length of the horizontally elongated hole 50 (see FIG. 6) formed in the upper portion of the corrugated steel plate 30 becomes long, the shear strength of the corrugated steel plate 30 decreases.

[0064] In contrast, in the present embodiment, the central portions of the corrugated steel plate 30 and the other wood surface material 80Y are joined by the joining bolts 62. Thereby, as shown in FIG. 7(A), when the central portion of the corrugated steel plate 30 moves in the lateral width direction along with the shear deformation of the corrugated steel plate 30, as indicated by the two-dot chain line, the other wood surface material 80Y moves in the lateral width direction of the corrugated steel plate 30 together with the joining bolts 62.

[0065] As a result, since the relative movement amount D2 in the lateral width direction between the upper portions of the corrugated steel plate 30 and the other wood surface material 80Y becomes small (D2 < D1), the required length of the horizontally elongated hole 50 (see FIG. 6) formed in the upper portion of the corrugated steel plate 30 can be shortened. Similarly, since the relative movement amount D2 in the lateral width direction between the lower portions of the corrugated steel plate 30 and the other wood surface material 80Y becomes small (D2 < D1), the required length of the horizontally elongated hole 50 (see FIG. 6) formed in the upper portion of the corrugated steel plate 30 can be shortened.

[0066] Therefore, it is possible to suppress a decrease in the shear strength of the corrugated steel plate 30 accompanying the shear deformation of the corrugated steel plate 30.

[0067] Furthermore, reinforcing plates 70 are provided around the elongated holes 50 in the corrugated steel plate 30. This suppresses damage to the area around the elongated holes 50 in the corrugated steel plate 30 as the corrugated steel plate 30 undergoes shear deformation.

[0068] Furthermore, the aesthetic appeal of the seismic wall 20 is improved by covering both sides of the corrugated steel plate 30 with a pair of wood-based paneling 80X and 80Y.

[0069] (modified version) Next, a modified example of the above embodiment will be described.

[0070] In the above embodiment, the central parts of the corrugated steel plate 30 and the other wood panel 80Y in the vertical direction are joined (fixed) by joining bolts 62. However, it is also possible to join (fix) not only the central parts of the corrugated steel plate 30 and the other wood panel 80Y in the vertical direction, but also the central parts of the corrugated steel plate 30 and the pair of wood panels 80X, 80Y in the vertical direction.

[0071] Furthermore, in the above embodiment, a pair of wood-based facing materials 80X and 80Y are attached to the corrugated steel plate 30. However, as shown in the modified example in Figure 8, the wood-based facing material 80Y may be attached to only one side of the corrugated steel plate 30. In this case, for example, a stiffening member 90 may be attached to the side of the corrugated steel plate 30 opposite to the wood-based facing material 80Y.

[0072] The stiffening member 90 is formed, for example, from an L-shaped steel beam. The stiffening member 90 is positioned along the vertical direction and is joined to the surface of the corrugated steel plate 30 by welding or bolts (not shown). This stiffening member 90 can also suppress buckling of the corrugated steel plate 30. The stiffening member 90 can be omitted as appropriate.

[0073] Furthermore, in the above embodiment, the connecting member is a connecting bolt 52. However, the connecting member is not limited to a connecting bolt 52; for example, it may be a stud bolt and nut, or a screw, etc.

[0074] Similarly, in the above embodiment, the central connecting member is a connecting bolt 62. However, the central connecting member is not limited to a connecting bolt 62; for example, it may be a stud bolt and nut, or a screw, etc.

[0075] Furthermore, in the above embodiment, a pair of wood paneling 80X, 80Y are provided with lag screw bolts 82 into which joining bolts 62 or connecting bolts 52 are screwed. However, the configuration of the joint or connecting portion of the pair of wood paneling 80X, 80Y is not limited to lag screw bolts 82 and can be appropriately changed depending on the configuration of the central joining member and the connecting member.

[0076] Furthermore, in the above embodiment, the stiffening surface material is a wood panel 80X, 80Y. However, the stiffening surface material is not limited to a wood panel 80X, 80Y; for example, it may be a fire-resistant board (fire-resistant surface material), etc. Other examples of stiffening surface materials include concrete panels, steel fiber reinforced concrete (SFRC) panels, glass fiber reinforced concrete (GRC) panels, gypsum boards, ALC panels, etc.

[0077] Although one embodiment of the present invention has been described above, the present invention is not limited to these embodiments, and various modifications may be used in appropriate combinations with one embodiment, and of course, the invention can be implemented in various forms without departing from the spirit of the present invention.
