EARTHQUAKE ENERGY ABSORPTION DEVICE, AND CONCRETE STRUCTURE USING THE EARTHQUAKE ENERGY ABSORPTION DEVICE
To reliably absorb energy during an earthquake without requiring large-scale construction.SOLUTION: In an earthquake energy absorption device, an energy absorption device main body 11 has a deforming portion 11c between an RC beam fixing portion 11a fixed to an RC beam that is a structural skeleton and a non-structural wall fixing portion 11b fixed to a non-structural wall, has three or more locations in total of the RC beam fixing portions 11a and the non-structural wall fixing portions 11b, and has two or more deforming portions 11c. The RC beam fixing portion 11a is provided with a structural skeleton connecting member 12 embedded in the RC beam and connecting the energy absorption device main body 11 to the RC beam. The non-structural wall fixing portion 11b is provided with a non-structural wall connecting member 13 embedded in the non-structural wall and connecting the energy absorption device main body 11 to the non-structural wall. The deforming portion 11c has a curved portion 11c1 that is curved so as to bulge outward in a short direction of the energy absorption device main body 11 to form a through hole 11c2, to weaken its strength compared to the RC beam fixing portion 11a and the non-structural wall fixing portion 11b.SELECTED DRAWING: Figure 2
【課題】大掛かりな施工を要せず、地震発生時のエネルギーを確実に吸収する。【解決手段】架構骨組であるＲＣ梁に固定されるＲＣ梁固定部１１ａと非構造壁に固定される非構造壁固定部１１ｂとの間に変形部１１ｃを有しており、ＲＣ梁固定部１１ａと非構造壁固定部１１ｂとを合わせて３箇所以上有し、かつ、変形部１１ｃを２箇所以上有しており、ＲＣ梁固定部１１ａにはＲＣ梁に埋設されてエネルギー吸収装置本体１１とＲＣ梁とを接合する架構骨組接合部材１２が設けられ、非構造壁固定部１１ｂには非構造壁に埋設されエネルギー吸収装置本体１１と非構造壁とを接合する非構造壁接合部材１３が設けられ、変形部１１ｃは、貫通孔１１ｃ２を形成するようエネルギー吸収装置本体１１の短手方向でかつ外側に向かって膨らむように湾曲した湾曲部１１ｃ１を有することにより、ＲＣ梁固定部１１ａおよび非構造壁固定部１１ｂよりも強度を弱体化させる。【選択図】図２
