Description

This invention relates to earthquake-resistant walls. A wooden seismic wall is known that ensures seismic performance using a wooden plate-like body formed by bonding and laminating timber (see, for example, Patent Document 1). The wooden seismic wall described in Patent Document 1 comprises a pair of wooden boards arranged opposite each other, each having notches at its four corners, and a steel plate positioned between the pair of wooden boards, with corners exposed through the notches and connected to the object to be connected. Japanese Patent Publication No. 2015-086517 This is a front view showing the configuration of a wooden seismic wall according to the first embodiment.This is an exploded perspective view showing the configuration of a wooden seismic wall according to the first embodiment.This is a perspective view showing the configuration of a wooden seismic wall according to the first embodiment.This is a front view showing the configuration of the connection device according to the first embodiment.This is a front view showing the configuration of a wooden seismic wall equipped with a rigidity adjustment beam according to the first embodiment.This is a front view showing the configuration of a wooden seismic wall according to the second embodiment.This is an exploded perspective view showing the configuration of a wooden seismic wall according to the second embodiment.This is a perspective view showing the configuration of a wooden seismic wall according to the second embodiment.This is a front view showing the configuration of a wooden seismic wall according to the third embodiment.This is an exploded perspective view showing the configuration of a wooden seismic wall according to the third embodiment. The following describes embodiments of the wooden seismic wall according to the present invention, with reference to the drawings. Buildings deform during earthquakes. Wooden seismic walls installed within buildings are subjected to loads in different directions depending on their installation location during an earthquake. The following embodiments illustrate wooden seismic walls equipped with dampers that function in response to loads occurring in different directions. [First Embodiment] As shown in Figure 1, the wooden seismic wall 1 (seismic wall) is fixed to a connection target such as a steel beam on the building side. The wooden seismic wall 1 has, for example, a wooden board 2 formed in the shape of a rectangular plate. The wooden board 2 is formed from, for example, a CLT (Cross Laminated Timber) member. A CLT member is a wood material formed by bonding and laminating wood to have sufficient strength and fire resistance. In the building, a first steel beam T1 is fixed to the ceiling side, and a second steel beam T2 is fixed to the floor side. The wooden board 2 is placed between the first steel beam T1 and the second steel beam T2. The upper part of the wooden board 2 is fixed to the first steel beam T1, which is the installation target and is located above it, via a fixing member 3. The fixing member 3 is fixed to the first steel beam T1 and the wooden board 2, for example, by bolts and nuts. The lower part of the wooden board 2 is connected to the second steel beam T2, which is the installation target and is located below it, via a connecting device 4. That is, the upper part of the wooden board 2 is fixed to the first steel beam T1 by the fixing member 3, and the lower part is fixed to the second steel beam T2 by the connecting device 4. The wooden seismic wall 1 according to the first embodiment is configured to prevent the wooden board 2 from being destroyed by horizontal loads that occur during an earthquake, for example. As shown in Figure 2, the connecting device 4 comprises a first connecting member 5 connected to the wooden board 2, a second connecting member 7 connected to the second steel beam T2, and a damper member 6 provided between the first connecting member 5 and the second connecting member 7. The first connecting member 5 is formed, for example, from a steel plate. The first connecting member 5 is formed, for example, in the shape of a rectangular plate. The first connecting member 5 is arranged upright in the vertical direction (Z-axis direction in the figure). Viewed along the depth direction (Y-axis direction in the figure), the first connecting member 5 is formed with a length in the width direction (X-axis direction in the figure) that is longer than its height in the vertical direction. In the upper half of the first connecting member 5, a plurality of first guide holes 5H1 are arranged along the width direction. The first guide holes 5H1 are formed, for example, as elongated holes along the vertical direction. The upper part of the first connecting member 5 is inserted, for example, into a storage hole (not shown) formed in the lower part of the wooden board 2. The storage hole has a space that accommodates the upper half of the first connecting member 5. Mul
