Description

[Technical field]

[0001] The present invention relates to a seismic wall structure comprising a frame body that is fitted into the structural surface of a column-beam structure and has a groove formed on its inner surface, and a plate-shaped wall body whose outer peripheral edge is inserted into the groove of the frame body, with an elastic structural sealing material interposed between at least one of both side surfaces of the groove and the outer peripheral edge of the wall body. [Background technology]

[0002] A known earthquake-resistant wall structure uses a plate-shaped wall body made of glass or the like as an earthquake-resistant element to ensure design (see, for example, Patent Document 1). In the earthquake-resistant wall structure described in Patent Document 1, the outer peripheral edge of a plate-shaped wall body (transparent surface material) made of glass or the like is inserted into a groove formed on the inner peripheral surface of a frame body (sash frame material) fitted into the structural surface of a column-beam frame. A viscous body that also functions as a sealant to prevent rainwater from entering is interposed between the groove of the frame body and the outer peripheral edge of the wall body, and the damping effect caused by the deformation of this viscous body makes it possible to absorb vibration energy caused by earthquakes or the like that is transmitted from the frame body to the wall body.

[0003] [Patent Document 1] JP 2001-193357 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the earthquake-resistant wall structure of Patent Document 1, although vibration energy can be absorbed, there is a limit to improving earthquake resistance and achieving an excellent wall ratio, even when, for example, a relatively brittle glass plate is used as the wall. That is, although the damping action due to the deformation of the viscous body is effective in absorbing vibration energy, when the change in the speed of the relative displacement of the wall body in the in-plane direction with respect to the frame body is small, the resistance to the external force transmitted from the frame body to the wall body is not exerted, so the contribution to improving the wall ratio is small. In addition, when the relative displacement of the wall body in the in-plane direction with respect to the frame body progresses and the deformation of the viscous body reaches its limit, a large external force is suddenly transmitted to the wall body, and the collapse of the wall body due to the transmission of the sudden external force becomes a problem. In view of this situation, the main object of the present invention is to provide a technology that can provide an excellent wall multiplier while effectively avoiding collapse of a wall body in an earthquake-resistant wall structure comprising a frame body that is fitted into the structural surface of a column-beam structure and has a groove formed on its inner surface, and a plate-shaped wall body whose outer peripheral edge is inserted into the groove of the frame body, and in which an elastic structural sealing material is interposed between at least one of both side surfaces of the groove and the outer peripheral edge of the wall body. [Means for solving the problem]

[0005] The first characteristic configuration of the present invention is a frame body that is fitted into the structural surface of a column-beam frame and has a groove formed on its inner peripheral surface; A plate-shaped wall body having an outer peripheral edge portion inserted into the groove portion of the frame body, A seismic wall structure in which an elastic structural sealant is interposed between at least one of the two side surfaces of the groove and an outer peripheral edge of the wall body, the frame body forms a bottom surface of the groove portion against which the outer peripheral end surface of the wall body abuts, and has a groove bottom plate portion formed in a plate shape along the outer peripheral end surface and provided adjacent to the outer internal space, The groove bottom plate portion is in a form that elastically bends and deforms in response to relative movement of the wall body to the frame body along the normal direction of the bottom surface of the groove portion, and functions as a first external force transmission means that elastically transmits an external force from the frame body to the wall body along the in-plane direction of the wall body.

[0006] According to this configuration, the outer peripheral edge of the plate-shaped wall is inserted into the groove formed on the inner peripheral surface of the frame fitted into the structural surface of the column-beam frame, and the groove bottom plate, to which the outer peripheral end face of the wall is abutted in the groove of the frame, is provided adjacent to an internal space on the outside, so that the groove bottom plate can be bent toward the external internal space. Therefore, the groove bottom plate can function as the first external force transmission means in a form in which it elastically bends and deforms following the relative movement of the wall to the frame along the normal direction of the bottom surface of the groove. The magnitude of the external force transmitted from the frame to the wall gradually increases according to the amount of bending deformation of the groove bottom plate accompanying the relative movement of the wall, so that it is possible to avoid abrupt transmission of the external force from the frame to the wall, and to effectively avoid the collapse of the wall. In addition, it is possible to effectively exert a resistance due to the rigidity of the wall against the external force transmitted from the frame to the wall, thereby improving earthquake resistance. Therefore, the present invention can provide a technology that can demonstrate an excellent wall multiplier while effectively avoiding collapse of the wall in an earthquake-resistant wall structure that comprises a frame body that is fitted into the structural surface of a column-beam structure and has a groove formed on its inner surface, and a plate-shaped wall body whose outer peripheral edge is inserted into the groove of the frame body, and in which an elastic structural sealing material is interposed between at least one of both side surfaces of the groove and the outer peripheral edge of the wall body.

[0007] A second characteristic configuration of the present invention is a frame body having a pair of side wall portions arranged on both side sides of the groove portion, and an outer peripheral plate portion that is installed on the outer peripheral end portions of the pair of side wall portions with an outer peripheral space interposed between the frame and the column-beam structure and has a substantially central portion fixed to the column-beam structure, and the groove bottom plate portion is installed on each of the pair of side wall portions with the internal space interposed between the frame and the outer peripheral plate portion, The outer peripheral plate portion is in a form that elastically bends and deforms in response to the relative movement of the frame body to the column-beam structure along the normal direction of the bottom surface of the groove portion, and functions as a second external force transmission means that elastically transmits an external force from the column-beam structure to the frame body along the in-plane direction of the wall body.

[0008] According to this configuration, an internal space is provided adjacent to the groove bottom plate portion of the frame body on the side of the outer peripheral plate portion opposite the bottom surface side of the groove portion where the outer peripheral end face of the wall body abuts, so that the groove bottom plate portion can be configured to be freely bent and deformed in response to relative movement of the wall body to the frame body along the normal direction to the bottom surface of the groove portion as the first external force transmission means described above. Furthermore, in the outer peripheral plate part, which is installed on the pair of side walls in the frame body like the groove bottom plate part and has a substantially central part fixed to the column-beam frame side, an outer peripheral space is provided adjacent to the column-beam frame side, and an internal space is provided adjacent to the groove bottom plate part, which is the opposite side, so that the outer peripheral plate part can be elastically bent and deformed following the relative movement of the frame body to the column-beam frame along the normal direction of the bottom surface of the groove part. Therefore, this outer peripheral plate part can function as the second external force transmission means in such a bending deformation form. And, since the magnitude of the external force transmitted from the column-beam frame to the frame body gradually increases according to the bending deformation amount of the outer peripheral plate part accompanying the relative movement of the frame body, it is possible to avoid a sudden external force being transmitted from the column-beam frame to the wall body through the frame body, and to effectively prevent the collapse of the frame body. Also, since the external force due to the rigidity of the wall body can be effectively expressed against the external force transmitted from the column-beam frame to the wall body through the frame body, it is possible to improve earthquake resistance.

[0009] The third characteristic configuration of the present invention is that at the joint between the vertical members and horizontal members that constitute the frame body, the groove bottom plate portion and the outer peripheral plate portion of the vertical members, and the groove bottom plate portion and the outer peripheral plate portion of the horizontal members are separated from each other.

[0010] According to this configuration, at the joints between the vertical members and horizontal members that make up the frame body, the grooved bottom plate portion and the outer peripheral plate portion of the vertical members and the grooved bottom plate portion and the outer peripheral plate portion of the horizontal members are separated from each other, so that they can be bent and deformed without interfering with each other, and these grooved bottom plate portion and outer peripheral plate portion can effectively function as the first external force transmission means and second external force transmission means described above.

[Diagram 5] Cross-sectional view of a seismic wall structure according to a second embodiment DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] An embodiment of a seismic wall structure according to the present invention will be described with reference to the drawings. As shown in Figure 1, the earthquake-resistant wall structure of this embodiment is configured in a column-beam frame 3 consisting of wooden columns 1 and beams 2, and in order to ensure design, a glass panel 30, which is a plate-like wall that separates the outdoors O from the indoors I, is used as an earthquake-resistant element. The earthquake-resistant wall structure includes a frame body 10 fitted into the structural surface 4 of the column-beam frame 3, and a plate-shaped glass panel 30 fitted into the frame body 10. The frame 10 includes a frame 10A of a first embodiment (see Figs. 3 and 4) and a frame 10B of a second embodiment (see Fig. 5), which will be described in detail later. In the frame 10, an elastic structural sealant 25 is interposed between at least one of the two side surfaces 11a of the groove 11 and the outer peripheral edge 30a of the glass sheet 30. That is, as shown in Figs. 3 and 5, the structural sealant 25 functions as a sealant for preventing rainwater from entering through the groove 11, and also functions as a material for elastically transmitting an external force from the frame 10 to the glass sheet 30 along the in-plane direction X of the glass sheet 30 in a form that elastically shears when the glass sheet 30 is displaced relative to the frame 10 along the in-plane direction X during an earthquake or the like. This produces a resistance to the external force transmitted from the frame 10 to the glass sheet 30, improving earthquake resistance. Furthermore, by forming the structural sealant 25 from a viscoelastic material, it is possible to absorb vibration energy caused by an earthquake or the like that is transmitted from the frame 10 to the glass plate 30 . Furthermore, the earthquake-resistant wall structure of this embodiment employs a configuration for effectively avoiding the collapse of the glass plate 30 while exhibiting an excellent wall factor. The earthquake-resistant wall structures of the first and second embodiments employing this configuration will be described below.

[0013] [First embodiment] First, the earthquake-resistant wall structure of the first embodiment will be described with reference to FIGS. The frame body 10A of the earthquake-resistant wall structure of this embodiment is composed of an aluminum extrusion extending along the column 1 or beam 2 of the column-beam structure 3, as shown in Figure 3, and is composed of a pair of side wall portions 12, a groove bottom plate portion 16, and an outer peripheral plate portion 14.

[0014] In the frame body 10A, each of the pair of side wall portions 12 is a plate-like portion that is perpendicular to the inner peripheral surface of the column-beam frame 3 and parallel to the in-plane direction X of the glass plate 30 inserted in the groove portion 11. The pair of side wall portions 12 are disposed parallel to each other on both side sides of the glass plate 30 on the outdoor O side and the indoor I side. Each of the pair of side wall portions 12 is provided across the connection portion with the outer peripheral plate portion 14 located on the outer peripheral side and the connection portion with the groove bottom plate portion 16 located on the inner peripheral side, and further, the inner peripheral end portion 12c extends toward the inner peripheral side (the right side in Figure 3) beyond the groove bottom plate portion 16. That is, the pair of side wall portions 12 are arranged parallel to each other, sandwiching a groove portion 11 formed on the inner side of the groove bottom plate portion 16, and form both side surfaces 11a of the groove portion 11 into which the outer peripheral edge portion 30a of the glass plate 30 is fitted. In the frame body 10A, elastic structural sealing material 25 is interposed in the gaps between both side surfaces 11a of the groove portion 11 formed by a pair of side wall portions 12 and both surfaces of the outer peripheral edge portion 30a of the glass plate 30 on the outdoor O side and indoor I side.

[0015] The groove bottom plate portion 16 is installed approximately in the central portion 12a of each of the pair of side wall portions 12, with an internal space 19 interposed between it and the outer peripheral plate portion 14 described later, and, like the outer peripheral plate portion 14, is a plate-shaped portion that is parallel to the inner peripheral surface of the column-beam structure 3 and perpendicular to the in-plane direction X of the glass plate 30. On the other hand, the outer peripheral plate portion 14 is installed on the outer peripheral end portions 12b of the pair of side wall portions 12 with an outer peripheral space 18 interposed between it and the column-beam frame 3, and is a plate-like portion that is parallel to the inner peripheral surface of the column-beam frame 3 and perpendicular to the in-plane direction X of the glass sheet 30. The outer peripheral plate portion 14 and the groove bottom plate portion 16 are disposed parallel to each other with an internal space 19 therebetween.

[0016] The inner peripheral surface side of the groove bottom plate portion 16 is adjacent to the groove portion 11. That is, the inner peripheral surface of the groove bottom plate portion 16 constitutes the bottom surface 11b of the groove portion 11 against which the outer peripheral end surface 30b of the glass plate 30 abuts via a rubber spacer 32. The normal direction of the bottom surface 11b of the groove portion 11 is parallel to the in-plane direction X of the glass plate 30. On the other hand, in the groove bottom plate portion 16, the outer peripheral surface side opposite to the inner peripheral surface side against which the glass plate 30 is abutted is adjacent to the internal space 19 interposed between it and the outer peripheral plate portion 14 described above. That is, since the surface of the groove bottom plate portion 16 opposite to the side where the glass plate 30 is in contact is adjacent to the internal space 19, the groove bottom plate portion 16 becomes a portion that can be elastically bent and deformed in response to the relative movement of the glass plate 30 with respect to the frame body 10A along the in-plane direction X of the glass plate 30 (the normal direction of the bottom surface 11b) as shown in Fig. 4. Then, in such a bending and deforming form, the groove bottom plate portion 16 functions as a first external force transmission means A that elastically transmits an external force from the frame body 10A to the glass plate 30 along the in-plane direction X of the glass plate 30.

[0017] A flange portion 14b extending outward is formed in the approximate center portion 14a on the outer peripheral surface side of the outer peripheral plate portion 14. On the other hand, a frame fixing bracket 5 made of a shaped material (L angle) having an L-shaped cross section is fixed to the inner peripheral surface of the column-beam frame 3 by a column-beam fixing screw 7. A spacer 8 is appropriately interposed between the inner peripheral surface of the column-beam frame 3 and the frame fixing bracket 5. The frame fixing bracket 5 is provided intermittently on the inner peripheral surface of the column-beam frame 3. For example, a frame fixing bracket 5 having an L-shape in front view, which is fixed to both the column 1 and the beam 2, is fixed to each of the four corners of the structural surface 4, and a frame fixing bracket 5 having an I-shape in front view, which is fixed to the column 1 or the beam 2, is arranged at a predetermined interval between the frame fixing brackets 5 at each of the four corners. In this embodiment, the frame fixing brackets 5 are provided intermittently, but the frame fixing brackets may be provided over the entire inner peripheral surface of the column-beam frame 3.

[0018] Then, the flange portion 14b of the outer peripheral plate portion 14 is fastened to the frame fixing bracket 5 fixed to the column-beam frame 3 by using a plurality of frame fixing screws 6, so that the approximate center portion 14a on the outer peripheral surface side of the outer peripheral plate portion 14 is fixed to the column-beam frame 3 with an outer peripheral space 18 interposed therebetween. And, the inner peripheral surface side of the outer peripheral plate portion 14 opposite to the outer peripheral surface side fixed to the inner column-beam frame 3 is adjacent to an internal space 19 interposed between it and a groove bottom plate portion 16 described later. That is, since the surface of the outer peripheral plate portion 14 opposite to the side fixed to the column-beam frame 3 is adjacent to the internal space 19, it becomes a portion that can elastically bend and deform in response to the relative movement of the frame body 10A with respect to the column-beam frame 3 along the in-plane direction X of the glass plate 30 (the normal direction of the bottom surface 11b) as shown in Fig. 4. Then, in such a bending and deforming form, the outer peripheral plate portion 14 functions as second external force transmission means B that elastically transmits an external force along the in-plane direction X of the glass plate 30 from the column-beam frame 3 to the frame body 10A.

[0019] In the earthquake-resistant wall structure of this embodiment, the groove bottom plate portion 16 functions as the first external force transmission means A, and the outer peripheral plate portion 14 functions as the second external force transmission means B, thereby effectively avoiding the collapse of the glass plate 30 while exhibiting an excellent wall ratio. That is, the magnitude of the external force transmitted from the frame body 10A to the glass plate 30 along the in-plane direction X gradually increases according to the amount of bending deformation of the groove bottom plate portion 16 accompanying the relative movement of the glass plate 30. This prevents a sudden external force from being transmitted from the frame body 10A to the glass plate 30, and effectively prevents the glass plate 30 from collapsing. Furthermore, the magnitude of the external force transmitted from the column-beam structure 3 to the frame body 10A along the in-plane direction X gradually increases according to the amount of bending deformation of the outer peripheral plate portion 14 accompanying the relative movement of the frame body 10A. This prevents a sudden external force from being transmitted from the column-beam structure 3 to the glass sheet 30 through the frame body 10A, effectively preventing the collapse of the frame body 10A. Furthermore, since the external force transmitted from the column-beam structure 3 through the frame body 10A to the glass plate 30 along the in-plane direction X is effectively expressed by the rigidity of the glass plate 30, it is possible to improve earthquake resistance and achieve an excellent wall factor of, for example, 3 or more.

[0020] The frame 10A of the earthquake-resistant wall structure of this embodiment is formed in a rectangular shape by joining a pair of vertical members 10V and a pair of horizontal members 10H together, as shown in Fig. 1. As shown in Fig. 2, the groove bottom plate portion 16 and the outer peripheral plate portion 14 of the vertical member 10V and the groove bottom plate portion 16 and the outer peripheral plate portion 14 of the horizontal member 10H are separated from each other. Specifically, the end of the groove bottom plate portion 16 of the vertical member 10V is cut out so that the end of the outer peripheral plate portion 14 of the vertical member 10V becomes an extension portion that extends beyond the end face of the groove bottom plate portion 16. The vertical members 10V and the horizontal members 10H, which are separated from each other, are arranged in such a state that the ends of the groove bottom plate portion 16 and the outer peripheral plate portion 14 of the horizontal member 10H abut against the inner peripheral surface of the extension portion of the outer peripheral plate portion 14 of the vertical member 10V, and the end of the groove bottom plate portion 16 of the vertical member 10V abuts against the inner peripheral surface of the groove bottom plate portion 16 of the horizontal member 10H. The inner peripheral surface of the outer peripheral plate portion 14 of the horizontal member 10H and the outer peripheral surface of the groove bottom plate portion 16 are fitted onto a U-shaped connecting hardware 20 fixed with screws 21 to the inner peripheral surface of the outer peripheral plate portion 14 of the vertical member 10V, thereby maintaining the arrangement of the vertical member 10V and the horizontal member 10H. At the joints between the vertical members 10V and the horizontal members 10H that constitute the frame 10A, the grooved bottom plate portion 16 and the outer peripheral plate portion 14 of the vertical members 10V and the grooved bottom plate portion 16 and the outer peripheral plate portion 14 of the horizontal members 10H are separated from each other, so they can bend and deform without interfering with each other. Therefore, the grooved bottom plate portion 16 can be bent and deformed well, and effectively functions as the first external force transmission means A described above. Furthermore, the outer peripheral plate portion 14 can be bent and deformed well, and effectively functions as the second external force transmission means B described above.

[0021] Second Embodiment Next, the configuration of the earthquake-resistant wall structure of the second embodiment will be described with reference to Fig. 5. Note that the same reference numerals are used for the same configurations as those of the above-mentioned first embodiment, and the description thereof may be omitted. The frame body 10B of the earthquake-resistant wall structure of this embodiment is composed of an aluminum extrusion extending along the column 1 or beam 2 of the column-beam structure 3, as shown in Figure 5, and consists of a pair of side wall portions 12, a groove bottom plate portion 16, and an outer peripheral plate portion 14.

[0022] In the frame body 10B, each of the pair of side wall portions 12 is a plate-like portion that is perpendicular to the inner peripheral surface of the column-beam frame 3 and parallel to the in-plane direction X of the glass plate 30 inserted in the groove portion 11. The pair of side wall portions 12 are disposed parallel to each other on both side sides of the groove portion 11 on the outdoor O side and the indoor I side. Each of the pair of side walls 12 is provided over a connecting portion with the outer peripheral plate portion 14 located on the outer peripheral side and a connecting portion with the groove bottom plate portion 16 located on the inner peripheral side. Furthermore, the indoor side wall portion 12I located on the indoor I side of the pair of side walls 12 has an inner peripheral end portion 12c extending toward the inner peripheral side (the right side in FIG. 5) beyond the bottom surface 11b of the groove portion 11. On the other hand, the outdoor side wall portion 12O located on the outdoor O side of the pair of side walls 12 has an inner peripheral end portion 12c at approximately the same position as the bottom surface 11b of the groove portion 11. A ridge attachment portion 35 is provided on the inner peripheral end portion 12c of the outdoor side wall portion 12O, and a ridge member 36 constituting the outer peripheral side surface 11a of the groove portion 11 is attached to the ridge attachment portion 35. That is, the indoor side wall portion 12I and the pressing member 36 are arranged parallel to each other with the groove portion 11 therebetween, and form both side surfaces 11a of the groove portion 11 into which the outer peripheral edge portion 30a of the glass sheet 30 is fitted. In the frame body 10A, an elastic structural sealant 25 is interposed in the gap between the side surface 11a on the indoor I side, which is formed by the indoor side wall portion 12I, and the indoor I side surface of the outer circumferential edge portion 30a of the glass plate 30. Also, a waterproof seal 27 for preventing the intrusion of rainwater is interposed in the gap between the side surface 11a on the outdoor O side, which is formed by the pressing member 36, and the outdoor O side surface of the outer circumferential edge portion 30a of the glass plate 30. In addition, in the frame body 10B of this embodiment, a hollow reinforcing frame portion 38 is provided adjacent to the indoor I side of the indoor side wall portion 12I.

[0023] The groove bottom plate portion 16 is installed between the inner end portion 12c of the outdoor side wall portion 12O and approximately the center portion 12a of the indoor side wall portion 12I, with an internal space 19 interposed between it and the outer peripheral plate portion 14 described later, and is a plate-shaped portion that is parallel to the inner peripheral surface of the column-beam structure 3 and perpendicular to the in-plane direction X of the glass plate 30, similar to the outer peripheral plate portion 14 described above. On the other hand, the outer peripheral plate portion 14 is installed on the outer peripheral end portions 12b of the pair of side wall portions 12 with an outer peripheral space 18 interposed between it and the column-beam frame 3, and is a plate-like portion that is parallel to the inner peripheral surface of the column-beam frame 3 and perpendicular to the in-plane direction X of the glass sheet 30. The outer peripheral plate portion 14 and the groove bottom plate portion 16 are disposed parallel to each other with an internal space 19 therebetween.

[0024] As in the first embodiment, the groove bottom plate portion 16 has a surface opposite to the side where the glass plate 30 is in contact adjacent to the internal space 19, and therefore serves as a portion that can be elastically bent and deformed in response to relative movement of the glass plate 30 with respect to the frame body 10A along the in-plane direction X of the glass plate 30 (the normal direction of the bottom surface 11b). In this manner of bending and deforming, the groove bottom plate portion 16 functions as a first external force transmission means A that elastically transmits an external force from the frame body 10A to the glass plate 30 along the in-plane direction X of the glass plate 30.

[0025] Meanwhile, as in the first embodiment, the surface of the outer peripheral plate portion 14 opposite to the side fixed to the column-beam frame 3 is adjacent to the internal space 19, and therefore the outer peripheral plate portion 14 becomes a portion that can be elastically bent and deformed following the relative movement of the frame body 10A with respect to the column-beam frame 3 along the in-plane direction X of the glass plate 30 (normal direction of the bottom surface 11b). In this manner of bending and deforming, the outer peripheral plate portion 14 functions as second external force transmission means B that elastically transmits an external force along the in-plane direction X of the glass plate 30 from the column-beam frame 3 to the frame body 10A.

[0026] In the earthquake-resistant wall structure of this embodiment, as in the first embodiment, the groove bottom plate portion 16 functions as the first external force transmission means A and the outer peripheral plate portion 14 functions as the second external force transmission means B, thereby effectively avoiding the collapse of the glass plate 30 while exhibiting an excellent wall ratio.

[0027] As shown in Fig. 1 and Fig. 2, in the frame body 10B of the earthquake-resistant wall structure of this embodiment, as in the first embodiment, at the joint between the vertical members 10V and the horizontal members 10H that constitute the frame body 10A, the groove bottom plate portion 16 and the outer peripheral plate portion 14 of the vertical members 10V and the groove bottom plate portion 16 and the outer peripheral plate portion 14 of the horizontal members 10H are separated from each other, so that they can bend and deform without interfering with each other. Therefore, the groove bottom plate portion 16 can be bent and deformed well, and effectively functions as the first external force transmission means A described above. Furthermore, the outer peripheral plate portion 14 can be bent and deformed well, and effectively functions as the second external force transmission means B described above.

[0028] [Another embodiment] Other embodiments of the present invention will be described below. Note that the configurations of the embodiments described below are not limited to being applied alone, but may also be applied in combination with the configurations of other embodiments.

[0029] (1) In the above embodiment, in the frame body 10, the groove bottom plate portion 16 functions as the first external force transmission means A that elastically transmits an external force from the frame body 10 to the glass plate 30 along the in-plane direction X of the glass plate 30. In addition, the outer peripheral plate portion 14 also functions as the second external force transmission means B that elastically transmits an external force from the column-beam structure 3 to the frame body 10 along the in-plane direction X of the glass plate 30. However, the outer peripheral plate portion 14 may be configured to transmit an external force from the column-beam structure 3 to the frame body 10 along the in-plane direction X of the glass plate 30 as is, rather than elastically, without being elastically bent and deformed.

[0030] (2) In the above embodiment, the frame body 10 is composed of a pair of side wall portions 12, a groove bottom plate portion 16, and an outer peripheral plate portion 14. However, the frame body 10 may be modified as appropriate within the scope of having such groove bottom plate portion 16, as long as it has the groove bottom plate portion 16 that constitutes the bottom surface 11b of the groove portion 11 against which the outer peripheral end surface 30b of the glass plate 30 abuts and is formed in a plate shape along the outer peripheral end surface 30b and is provided adjacent to the outer internal space 19.

A frame body that is fitted into the structural surface of the column-beam frame and has a groove formed on its inner peripheral surface; A plate-shaped wall body having an outer peripheral edge portion inserted into the groove portion of the frame body, A seismic wall structure in which an elastic structural sealant is interposed between at least one of the two side surfaces of the groove and an outer peripheral edge of the wall body, the frame body forms a bottom surface of the groove portion against which the outer peripheral end surface of the wall body abuts, and has a groove bottom plate portion formed in a plate shape along the outer peripheral end surface and provided adjacent to the outer internal space, A shear wall structure in which the groove bottom plate portion elastically bends and deforms in response to the relative movement of the wall body relative to the frame body along the normal direction of the bottom surface of the groove portion, and functions as a first external force transmission means for elastically transmitting an external force from the frame body to the wall body along the in-plane direction of the wall body.

2. The frame body includes a pair of side wall portions arranged on both sides of the groove portion, and an outer peripheral plate portion that is installed on the outer peripheral end portions of each of the pair of side wall portions with an outer peripheral space interposed between the pair of side wall portions and the column-beam structure, and has a substantially central portion fixed to the column-beam structure side, and the groove bottom plate portion is installed on each of the pair of side wall portions with the internal space interposed between the pair of side wall portions and the outer peripheral plate portion, The earthquake-resistant wall structure described in claim 1, wherein the outer peripheral plate portion functions as a second external force transmission means for elastically transmitting an external force from the column-beam structure to the frame body along an in-plane direction of the wall body, by elastically bending and deforming in response to the relative movement of the frame body to the column-beam structure along the normal direction of the bottom surface of the groove portion.

3. 3. The earthquake-resistant wall structure according to claim 2, wherein at the joints between the vertical members and the horizontal members constituting the frame body, the groove bottom plate portion and the outer peripheral plate portion of the vertical members and the groove bottom plate portion and the outer peripheral plate portion of the horizontal members are separated from each other.
