Description

本発明は、建物に関する。   The present invention relates to a building.

建物には、水平方向に間隔を置かれた一対の耐震壁と、該耐震壁を連結する梁とを含むものがある。前記梁は、前記耐震壁の間に配置された、コンクリートからなる梁部材を有し、該梁部材は、その一端部が一方の耐震壁に、その他端部が他方の耐震壁にそれぞれ固定されている。前記一方の耐震壁と前記他方の耐震壁との間の間隔は、前記建物の耐震性を損ねないようにするため、比較的短い。このため、地震時に各耐震壁が水平力を受けて前記一方の耐震壁が前記他方の耐震壁に対して上下方向に動くことにより、前記梁部材に比較的大きいせん断力が生じる。   Some buildings include a pair of seismic walls spaced apart in the horizontal direction and beams connecting the seismic walls. The beam has a beam member made of concrete disposed between the earthquake-resistant walls, and one end portion of the beam member is fixed to one earthquake-resistant wall and the other end portion is fixed to the other earthquake-resistant wall. ing. The distance between the one earthquake-resistant wall and the other earthquake-resistant wall is relatively short so as not to impair the earthquake resistance of the building. For this reason, each earthquake-resistant wall receives a horizontal force during an earthquake, and the one earthquake-resistant wall moves in the vertical direction with respect to the other earthquake-resistant wall, so that a relatively large shear force is generated in the beam member.

従来、前記梁部材の内部に、前記梁部材の前記一端部の上端部分と前記他端部の下端部分とを結ぶ第１直線の方向に伸びる第１鉄筋と、前記梁部材の前記一端部の下端部分と前記他端部の上端部分とを結ぶ第２直線の方向に伸びる第２鉄筋とが配置されているものがある（特許文献１参照）。このようにして前記梁になされた配筋はＸ形配筋と呼ばれている。   Conventionally, a first rebar extending in a first straight line connecting the upper end portion of the one end of the beam member and the lower end portion of the other end of the beam member, and the one end of the beam member inside the beam member, There is one in which a second reinforcing bar extending in the direction of a second straight line connecting the lower end portion and the upper end portion of the other end portion is disposed (see Patent Document 1). The bar arrangement made on the beam in this way is called X-type bar arrangement.

各耐震壁が前記水平力を受けて前記一方の耐震壁が前記他方の耐震壁に対して下方へ動いているとき、前記第１鉄筋は、両耐震壁から受ける圧縮力に抵抗し、前記第２鉄筋は、両耐震壁から受ける引張力に抵抗する。これにより、前記一方の耐震壁の前記他方の耐震壁に対する下方への動きを妨げて、前記梁部材に生じる前記せん断力を低減させることができる。また、前記一方の耐震壁が前記他方の耐震壁に対して上方へ動いているとき、前記第１鉄筋は、両耐震壁から受ける引張力に抵抗し、前記第２鉄筋は、両耐震壁から受ける圧縮力に抵抗する。これにより、前記一方の耐震壁の前記他方の耐震壁に対する上方への動きを妨げて、前記梁部材に生じる前記せん断力を低減させることができる。このため、前記梁部材のせん断破壊を防止することができる。   When each seismic wall receives the horizontal force and the one seismic wall moves downward relative to the other seismic wall, the first rebar resists the compressive force received from both seismic walls, and 2 Rebars resist the tensile force received from both seismic walls. Thereby, the downward movement of the one earthquake-resistant wall with respect to the other earthquake-resistant wall can be prevented, and the shear force generated in the beam member can be reduced. When the one seismic wall moves upward relative to the other seismic wall, the first rebar resists the tensile force received from both seismic walls, and the second rebar moves from both seismic walls. Resists the compressive force it receives. Thereby, the upward movement of the one earthquake-resistant wall with respect to the other earthquake-resistant wall can be prevented, and the shear force generated in the beam member can be reduced. For this reason, shear failure of the beam member can be prevented.

前記一方の耐震壁が前記他方の耐震壁に対して下方へ動いているとき、前記一方の耐震壁及び前記他方の耐震壁がそれぞれ前記梁部材の前記一端部の前記上端部分及び前記他端部の前記下端部分を圧縮する。これにより、前記梁部材は両耐震壁から前記第１直線の方向の圧縮力を受け、前記梁部材の前記一端部の前記上端部分及び前記他端部の前記下端部分が破壊されたり、前記梁部材の全部にひび割れが生じたりすることがある。   When the one seismic wall moves downward relative to the other seismic wall, the one seismic wall and the other seismic wall are respectively the upper end portion and the other end portion of the one end portion of the beam member. Compress the lower end portion. As a result, the beam member receives a compressive force in the direction of the first straight line from both earthquake-resistant walls, and the upper end portion of the one end portion and the lower end portion of the other end portion of the beam member are destroyed, or the beam The entire member may be cracked.

また、前記一方の耐震壁が前記他方の耐震壁に対して上方へ動いているとき、前記一方の耐震壁及び前記他方の耐震壁がそれぞれ前記梁部材の前記一端部の前記下端部分及び前記他端部の前記上端部分を圧縮する。これにより、前記梁部材は両耐震壁から前記第２直線の方向の圧縮力を受け、前記梁部材の前記一端部の前記下端部分及び前記他端部の前記上端部分が破壊されたり、前記梁部材の全部にひび割れが生じたりすることがある。   Further, when the one seismic wall is moving upward with respect to the other seismic wall, the one seismic wall and the other seismic wall are respectively the lower end portion and the other of the one end portion of the beam member. The upper end portion of the end portion is compressed. As a result, the beam member receives a compressive force in the direction of the second straight line from both earthquake-resistant walls, and the lower end portion of the one end portion and the upper end portion of the other end portion of the beam member are destroyed, or the beam The entire member may be cracked.

本発明の目的は、間隔を置かれた一対の耐震壁の間に配置された梁部材が地震時に前記耐震壁により圧縮されて損傷を受けることを防止することである。   An object of the present invention is to prevent a beam member disposed between a pair of spaced earthquake-resistant walls from being damaged by being compressed by the earthquake-resistant wall during an earthquake.

本発明は、前記梁部材の一端部の上端部分及び下端部分のそれぞれが一方の耐震壁から間隔を置かれ、前記梁部材の他端部の上端部分及び下端部分のそれぞれが他方の耐震壁から間隔を置かれるようにする。これにより、地震時に前記梁部材が両耐震壁により圧縮され難くなるようにし、前記梁部材が損傷を受けるのを防止する。   In the present invention, each of the upper end portion and the lower end portion of one end portion of the beam member is spaced from one earthquake-resistant wall, and each of the upper end portion and the lower end portion of the other end portion of the beam member is separated from the other earthquake-resistant wall. Allow to be spaced. This prevents the beam member from being compressed by the two seismic walls during an earthquake and prevents the beam member from being damaged.

本発明に係る建物は、水平方向に間隔を置かれた一対の耐震壁と、該耐震壁を連結する梁とを含み、該梁は、前記耐震壁の間に配置され、一端部が一方の耐震壁に、他端部が他方の耐震壁にそれぞれ固定された、コンクリートからなる梁部材を有する。前記梁部材の前記一端部は、前記一方の耐震壁に結合された中央部分と、それぞれが前記中央部分から前記水平方向における内方へ隔てられ、前記一方の耐震壁から間隔を置かれた上端部分及び下端部分とを有し、前記梁部材の前記他端部は、前記他方の耐震壁に結合された中央部分と、それぞれが前記中央部分から前記水平方向における内方へ隔てられ、前記他方の耐震壁から間隔を置かれた上端部分及び下端部分とを有する。   A building according to the present invention includes a pair of seismic walls spaced apart in the horizontal direction and a beam connecting the seismic walls, the beam being disposed between the seismic walls, and one end portion of one of the seismic walls. The seismic wall has a beam member made of concrete with the other end fixed to the other seismic wall. The one end of the beam member has a central portion coupled to the one seismic wall, and an upper end spaced apart from the one seismic wall, each spaced inward from the central portion in the horizontal direction. The other end of the beam member is separated from the central portion inward in the horizontal direction by the central portion coupled to the other earthquake-resistant wall, And an upper end and a lower end spaced from the seismic wall.

前記梁部材の前記一端部の前記上端部分及び前記下端部分のそれぞれが前記一方の耐震壁から間隔を置かれ、前記梁部材の前記他端部の前記上端部分及び前記下端部分のそれぞれが前記他方の耐震壁から間隔を置かれているため、地震時に各耐震壁が前記水平方向の力を受けて前記一方の耐震壁が前記他方の耐震壁に対して下方へ動いているときに前記一方の耐震壁及び前記他方の耐震壁がそれぞれ前記梁部材の前記一端部の前記上端部分及び前記他端部の前記下端部分を圧縮することはない。これにより、前記梁部材の前記一端部の前記上端部分及び前記他端部の前記下端部分が破壊されたり、前記梁部材の全部にひび割れが生じたりすることを防止することができる。   Each of the upper end portion and the lower end portion of the one end portion of the beam member is spaced from the one earthquake-resistant wall, and each of the upper end portion and the lower end portion of the other end portion of the beam member is the other When the earthquake-resistant wall is moved downward relative to the other earthquake-resistant wall, each of the earthquake-resistant walls receives the horizontal force at the time of an earthquake. The earthquake-resistant wall and the other earthquake-resistant wall do not compress the upper end portion of the one end portion and the lower end portion of the other end portion of the beam member, respectively. Thereby, it is possible to prevent the upper end portion of the one end portion of the beam member and the lower end portion of the other end portion from being broken or cracking of the entire beam member.

また、地震時に各耐震壁が前記水平方向の力を受けて前記一方の耐震壁が前記他方の耐震壁に対して上方へ動いているときに前記一方の耐震壁及び前記他方の耐震壁がそれぞれ前記梁部材の前記一端部の前記下端部分及び前記他端部の前記上端部分を圧縮することはない。これにより、前記梁部材の前記一端部の前記下端部分及び前記他端部の前記上端部分が破壊されたり、前記梁部材の全部にひび割れが生じたりすることを防止することができる。   In addition, when each earthquake-resistant wall receives the horizontal force during an earthquake and the one earthquake-resistant wall moves upward relative to the other earthquake-resistant wall, the one earthquake-resistant wall and the other earthquake-resistant wall are respectively The lower end portion of the one end portion of the beam member and the upper end portion of the other end portion are not compressed. Thereby, it can prevent that the said lower end part of the said one end part of the said beam member and the said upper end part of the said other end part are destroyed, or a crack arises in all the said beam members.

前記梁は、前記梁部材の内部に配置された、前記梁部材の前記一端部の前記上端部分と前記他端部の前記下端部分とを結ぶ第１直線の方向に伸びる少なくとも１本の第１鉄筋と、前記梁部材の前記一端部の前記下端部分と前記他端部の前記上端部分とを結ぶ第２直線の方向に伸びる少なくとも１本の第２鉄筋とを有する。前記第１鉄筋は、該第１鉄筋の一端部が前記梁部材の前記一端部の前記上端部分を経て伸び、前記一方の耐震壁に固定され、前記第１鉄筋の他端部が前記梁部材の前記他端部の前記下端部分を経て伸び、前記他方の耐震壁に固定されている。前記第２鉄筋は、該第２鉄筋の一端部が前記梁部材の前記一端部の前記下端部分を経て伸び、前記一方の耐震壁に固定され、前記第２鉄筋の他端部が前記梁部材の前記他端部の前記上端部分を経て伸び、前記他方の耐震壁に固定されている。   The beam is disposed inside the beam member, and extends in a direction of a first straight line connecting the upper end portion of the one end portion and the lower end portion of the other end portion of the beam member. A reinforcing bar, and at least one second reinforcing bar extending in the direction of a second straight line connecting the lower end portion of the one end portion of the beam member and the upper end portion of the other end portion. The first reinforcing bar has one end portion of the first reinforcing bar extending through the upper end portion of the one end portion of the beam member, and is fixed to the one earthquake-resistant wall, and the other end portion of the first reinforcing bar is the beam member. Extending through the lower end portion of the other end portion and fixed to the other earthquake-resistant wall. The second reinforcing bar has one end of the second reinforcing bar extending through the lower end portion of the one end of the beam member and is fixed to the one earthquake-resistant wall, and the other end of the second reinforcing bar is the beam member. Extending through the upper end portion of the other end, and fixed to the other earthquake-resistant wall.

前記一方の耐震壁が前記他方の耐震壁に対して下方へ動いているとき、前記第１鉄筋は、両耐震壁から受ける圧縮力に抵抗し、前記第２鉄筋は、両耐震壁から受ける引張力に抵抗する。これにより、前記一方の耐震壁の前記他方の耐震壁に対する下方への動きを妨げて、前記梁部材に生じるせん断力を低減させることができる。また、前記一方の耐震壁が前記他方の耐震壁に対して上方へ動いているとき、前記第１鉄筋は、両耐震壁から受ける引張力に抵抗し、前記第２鉄筋は、両耐震壁から受ける圧縮力に抵抗する。これにより、前記一方の耐震壁の前記他方の耐震壁に対する上方への動きを妨げて、前記梁部材に生じるせん断力を低減させることができる。このため、前記梁部材のせん断破壊を防止することができる。   When the one seismic wall moves downward relative to the other seismic wall, the first reinforcing bar resists the compressive force received from both seismic walls, and the second reinforcing bar receives the tensile force received from both seismic walls. Resist the force. Thereby, the downward movement with respect to the said other earthquake-resistant wall of said one earthquake-resistant wall can be prevented, and the shear force which arises in the said beam member can be reduced. When the one seismic wall moves upward relative to the other seismic wall, the first rebar resists the tensile force received from both seismic walls, and the second rebar moves from both seismic walls. Resists the compressive force it receives. Thereby, the upward movement of the one earthquake-resistant wall relative to the other earthquake-resistant wall can be prevented, and the shearing force generated in the beam member can be reduced. For this reason, shear failure of the beam member can be prevented.

前記梁部材の前記一端部の前記上端部分及び前記下端部分のそれぞれが前記一方の耐震壁から間隔を置かれ、前記梁部材の前記他端部の前記上端部分及び前記下端部分のそれぞれが前記他方の耐震壁から間隔を置かれているため、前記一方の耐震壁が前記他方の耐震壁に対して下方へ動いているとき、両耐震壁は、前記梁部材により抵抗されることなく、より効果的に、前記第１鉄筋に圧縮力を、前記第２鉄筋に引張力をそれぞれ加えることができる。これにより、前記引張力により前記第２鉄筋を降伏させることに加えて、前記圧縮力により前記第１鉄筋を降伏させることによっても、地震時に生じた振動エネルギーを吸収することができる。   Each of the upper end portion and the lower end portion of the one end portion of the beam member is spaced from the one earthquake-resistant wall, and each of the upper end portion and the lower end portion of the other end portion of the beam member is the other Since the one seismic wall is moving downward with respect to the other seismic wall, the two seismic walls are not resisted by the beam members and are more effective. In particular, a compressive force can be applied to the first rebar and a tensile force can be applied to the second rebar. Thereby, in addition to yielding the second reinforcing bar by the tensile force, vibration energy generated during an earthquake can be absorbed also by yielding the first reinforcing bar by the compressive force.

また、前記一方の耐震壁が前記他方の耐震壁に対して上方へ動いているとき、両耐震壁は、前記梁部材により抵抗されることなく、より効果的に、前記第１鉄筋に引張力を、前記第２鉄筋に圧縮力をそれぞれ加えることができる。これにより、前記引張力により前記第１鉄筋を降伏させることに加えて、前記圧縮力により前記第２鉄筋を降伏させることによっても、地震時に生じた振動エネルギーを吸収することができる。このため、前記振動エネルギーの吸収効果を高めることができる。   Further, when the one seismic wall is moving upward with respect to the other seismic wall, the two seismic walls are not effectively resisted by the beam member, and more effectively, the tensile force is applied to the first reinforcing bar. The compression force can be applied to the second reinforcing bars. Thereby, in addition to yielding the first rebar by the tensile force, the vibration energy generated during the earthquake can be absorbed also by yielding the second rebar by the compressive force. For this reason, the absorption effect of the vibration energy can be enhanced.

前記梁は、前記梁部材の前記一端部の前記上端部分及び前記他端部の前記下端部分のそれぞれの内部に配置され、前記第１鉄筋を取り巻く第１スパイラル筋と、前記梁部材の前記一端部の前記下端部分及び前記他端部の前記上端部分のそれぞれの内部に配置され、前記第２鉄筋を取り巻く第２スパイラル筋とを有するものとすることができる。前記第１スパイラル筋は、前記梁部材の前記一端部の前記上端部分又は前記他端部の前記下端部分を補強し、前記第２スパイラル筋は、前記梁部材の前記一端部の前記下端部分又は前記他端部の前記上端部分を補強する。   The beam is disposed inside each of the upper end portion of the one end portion of the beam member and the lower end portion of the other end portion, and a first spiral rebar surrounding the first rebar, and the one end of the beam member It has a 2nd spiral reinforcement which is arranged inside each of the lower end part of the part and the upper end part of the other end part, and surrounds the 2nd reinforcing bar. The first spiral reinforcement reinforces the upper end portion of the one end portion of the beam member or the lower end portion of the other end portion, and the second spiral reinforcement is the lower end portion of the one end portion of the beam member or The upper end portion of the other end portion is reinforced.

ところで、前記梁部材の前記一端部の前記上端部分と前記一方の耐震壁との間及び前記梁部材の前記他端部の前記下端部分と前記他方の耐震壁との間のそれぞれにおいて、前記第１鉄筋は、両耐震壁から圧縮力を受けたとき、前記梁部材により拘束されることなく変形しようとする。このため、前記梁部材の前記一端部の前記上端部分及び前記他端部の前記下端部分は損傷を受けやすい。前記第１スパイラル筋が前記梁部材の前記一端部の前記上端部分又は前記他端部の前記下端部分を補強することにより、前記梁部材の前記一端部の前記上端部分及び前記他端部の前記下端部分が損傷を受けるのを防ぐことができる。   By the way, in each of the space between the upper end portion of the one end portion of the beam member and the one earthquake-resistant wall and between the lower end portion of the other end portion of the beam member and the other earthquake-resistant wall. One rebar attempts to deform without being constrained by the beam member when it receives a compressive force from both seismic walls. For this reason, the upper end portion of the one end portion of the beam member and the lower end portion of the other end portion are easily damaged. The first spiral reinforcement reinforces the upper end portion of the one end portion of the beam member or the lower end portion of the other end portion, thereby the upper end portion of the one end portion and the other end portion of the beam member. It is possible to prevent the lower end portion from being damaged.

また、前記梁部材の前記一端部の前記下端部分と前記一方の耐震壁との間及び前記梁部材の前記他端部の前記上端部分と前記他方の耐震壁との間のそれぞれにおいて、前記第２鉄筋は、両耐震壁から圧縮力を受けたとき、前記梁部材により拘束されることなく変形しようとする。このため、前記梁部材の前記一端部の前記下端部分及び前記他端部の前記上端部分は損傷を受けやすい。前記第２スパイラル筋が前記梁部材の前記一端部の前記下端部分又は前記他端部の前記上端部分を補強することにより、前記梁部材の前記一端部の前記下端部分及び前記他端部の前記上端部分が損傷を受けるのを防ぐことができる。   Further, in each of the space between the lower end portion of the one end portion of the beam member and the one earthquake-resistant wall and between the upper end portion of the other end portion of the beam member and the other earthquake-resistant wall, The two reinforcing bars attempt to deform without being constrained by the beam members when they are subjected to compressive forces from the two seismic walls. For this reason, the lower end portion of the one end portion of the beam member and the upper end portion of the other end portion are easily damaged. The second spiral reinforcement reinforces the lower end portion of the one end portion of the beam member or the upper end portion of the other end portion, thereby the lower end portion of the one end portion and the other end portion of the beam member. It is possible to prevent the upper end portion from being damaged.

前記第１鉄筋は、該第１鉄筋を覆う第１シースにより前記梁部材から隔てられており、前記第２鉄筋は、該第２鉄筋を覆う第２シースにより前記梁部材から隔てられている。このため、前記一方の耐震壁が前記他方の耐震壁に対して下方へ動いているとき、前記第１鉄筋が両耐震壁から受けた圧縮力と、前記第２鉄筋が両耐震壁から受けた引張力とが前記梁部材に伝わって該梁部材が損傷を受けることはない。また、前記一方の耐震壁が前記他方の耐震壁に対して上方へ動いているとき、前記第１鉄筋が両耐震壁から受けた引張力と、前記第２鉄筋が両耐震壁から受けた圧縮力とが前記梁部材に伝わって該梁部材が損傷を受けることはない。   The first reinforcing bar is separated from the beam member by a first sheath that covers the first reinforcing bar, and the second reinforcing bar is separated from the beam member by a second sheath that covers the second reinforcing bar. Therefore, when the one seismic wall is moving downward relative to the other seismic wall, the first reinforcing bar receives the compressive force received from both the seismic walls, and the second reinforcing bar receives from both the seismic walls. The tensile force is not transmitted to the beam member, and the beam member is not damaged. Further, when the one seismic wall is moving upward with respect to the other seismic wall, the first reinforcing bar receives the tensile force received from both the seismic walls, and the second reinforcing bar receives the compression received from both the seismic walls. The force is not transmitted to the beam member and the beam member is not damaged.

前記梁部材の前記一端部の前記上端部分及び前記下端部分のそれぞれと前記一方の耐震壁との間に第１緩衝材が配置されており、前記梁部材の前記他端部の前記上端部分及び前記下端部分のそれぞれと前記他方の耐震壁との間に第２緩衝材が配置されている。地震時に各耐震壁が水平力を受けたとき、前記第１緩衝材は、前記一方の耐震壁が前記梁部材の前記一端部の前記上端部分又は前記下端部分に当たるのを阻止し、前記第２緩衝材は、前記他方の耐震壁が前記梁部材の前記他端部の前記上端部分又は前記下端部分に当たるのを阻止する。   A first cushioning material is disposed between each of the upper end portion and the lower end portion of the one end portion of the beam member and the one earthquake-resistant wall, and the upper end portion of the other end portion of the beam member and A second cushioning material is disposed between each of the lower end portions and the other earthquake-resistant wall. When each seismic wall receives a horizontal force during an earthquake, the first shock absorber prevents the one seismic wall from hitting the upper end portion or the lower end portion of the one end portion of the beam member, The buffer material prevents the other earthquake-resistant wall from hitting the upper end portion or the lower end portion of the other end portion of the beam member.

本発明に係る建物は、水平方向に間隔を置かれた一対の柱と、該柱を連結する梁とを含み、該梁は、前記柱の間に配置され、一端部が一方の柱に、他端部が他方の柱にそれぞれ固定された、コンクリートからなる梁部材を有する。前記梁部材の前記一端部は、前記一方の柱に結合された中央部分と、それぞれが前記中央部分から前記水平方向における内方へ隔てられ、前記一方の柱から間隔を置かれた上端部分及び下端部分とを有し、前記梁部材の前記他端部は、前記他方の柱に結合された中央部分と、それぞれが前記中央部分から前記水平方向における内方へ隔てられ、前記他方の柱から間隔を置かれた上端部分及び下端部分とを有する。   The building according to the present invention includes a pair of columns spaced in the horizontal direction, and a beam connecting the columns, the beam is disposed between the columns, and one end portion of the column is one column. It has a beam member made of concrete with the other end fixed to the other pillar. The one end of the beam member includes a central portion coupled to the one column, an upper end portion spaced from the one column, each spaced inwardly from the central portion and inward in the horizontal direction, and A lower end portion, and the other end portion of the beam member is separated from an inner portion in the horizontal direction from the central portion, and a central portion coupled to the other pillar, and from the other pillar. It has an upper end portion and a lower end portion that are spaced apart.

前記梁部材の前記一端部の前記上端部分及び前記下端部分のそれぞれが前記一方の柱から間隔を置かれ、前記梁部材の前記他端部の前記上端部分及び前記下端部分のそれぞれが前記他方の柱から間隔を置かれているため、地震時に各柱が前記水平方向の力を受けて前記一方の柱が前記他方の柱に対して下方へ動いているときに前記一方の柱及び前記他方の柱がそれぞれ前記梁部材の前記一端部の前記上端部分及び前記他端部の前記下端部分を圧縮することはない。これにより、前記梁部材の前記一端部の前記上端部分及び前記他端部の前記下端部分が破壊されたり、前記梁部材の全部にひび割れが生じたりするのを防ぐことができる。   Each of the upper end portion and the lower end portion of the one end portion of the beam member is spaced from the one column, and each of the upper end portion and the lower end portion of the other end portion of the beam member is the other end. Since the columns are spaced from each other, each column receives the horizontal force during an earthquake, and the one column and the other column move when the one column moves downward relative to the other column. Each column does not compress the upper end portion of the one end portion and the lower end portion of the other end portion of the beam member. As a result, it is possible to prevent the upper end portion of the one end portion of the beam member and the lower end portion of the other end portion from being broken or cracking of the entire beam member.

また、地震時に各柱が前記水平方向の力を受けて前記一方の柱が前記他方の柱に対して上方へ動いているときに前記一方の柱及び前記他方の柱がそれぞれ前記梁部材の前記一端部の前記下端部分及び前記他端部の前記上端部分を圧縮することはない。これにより、前記梁部材の前記一端部の前記下端部分及び前記他端部の前記上端部分が破壊されたり、前記梁部材の全部にひび割れが生じたりするのを防ぐことができる。   In addition, when each column receives the horizontal force during an earthquake and the one column moves upward relative to the other column, the one column and the other column are each of the beam member The lower end portion at one end and the upper end portion at the other end are not compressed.

また、地震時に前記耐震壁及び前記柱のそれぞれが前記水平方向の力を受けて前記耐震壁が前記柱に対して上方へ動いているときに前記耐震壁及び前記柱がそれぞれ前記梁部材の前記一端部の前記下端部分及び前記他端部の前記上端部分を圧縮することはない。これにより、前記梁部材の前記一端部の前記下端部分及び前記他端部の前記上端部分が破壊されたり、前記梁部材の全部にひび割れが生じたりするのを防ぐことができる。   In addition, when the earthquake-resistant wall and the column receive the horizontal force during the earthquake and the earthquake-resistant wall is moving upward with respect to the column, the earthquake-resistant wall and the column are each of the beam member. The lower end portion at one end and the upper end portion at the other end are not compressed.

Each first sheath 60 and each second sheath 62 are filled with grease 64.

梁１４は、第１鉄筋４８と第２鉄筋５０とに加えて、前記第２水平方向に間隔を置いて梁部材１８の内部に配置され、それぞれが前記第１水平方向に伸びる複数の上端筋（図示せず）と、該上端筋の下方にあって前記第２水平方向に間隔を置いて梁部材１８の内部に配置され、それぞれが前記第１水平方向に伸びる複数の下端筋（図示せず）とを有する。第１鉄筋４８は、梁部材１８の一端部２０において前記上端筋の間に位置し、梁部材１８の他端部２２において前記下端筋の間に位置する。第２鉄筋５０は、梁部材１８の一端部２０において前記下端筋の間に位置し、梁部材１８の他端部２２において前記上端筋の間に位置する。   In addition to the first reinforcing bar 48 and the second reinforcing bar 50, the beam 14 is arranged inside the beam member 18 with a spacing in the second horizontal direction, and each of the upper end bars extends in the first horizontal direction.

梁部材１８の一端部２０の上端部分２６と一方の耐震壁１０との間及び梁部材１８の一端部２０の下端部分２８と一方の耐震壁１０との間のそれぞれに第１緩衝材６６が配置されている（図１）。梁部材１８の他端部２２の上端部分３８と他方の耐震壁１２との間及び梁部材１８の他端部２２の下端部分４０と他方の耐震壁１２との間のそれぞれに第２緩衝材６８が配置されている。第１緩衝材６６及び第２緩衝材６８のそれぞれは、いわゆるスリット材であり、例えば、発泡ポリエチレンからなる。   The first buffer material 66 is provided between the upper end portion 26 of the one end portion 20 of the beam member 18 and the one earthquake-resistant wall 10 and between the lower end portion 28 of the one end portion 20 of the beam member 18 and the one earthquake-resistant wall 10. Is arranged (FIG. 1). The second cushioning material is provided between the upper end portion 38 of the other end portion 22 of the beam member 18 and the other earthquake-resistant wall 12 and between the lower end portion 40 of the other end portion 22 of the beam member 18 and the other earthquake-resistant wall 12. 68 is arranged. Each of the first buffer material 66 and the second buffer material 68 is a so-called slit material, and is made of, for example, foamed polyethylene.

地震時に各耐震壁１０、１２が前記第１水平方向の力を受けて振動することにより、一方の耐震壁１０は他方の耐震壁１２に対して上下方向に動く。図３に示すように、一方の耐震壁１０が他方の耐震壁１２に対して下方へ動いているとき、梁部材１８の一端部２０は一方の耐震壁１０から下向き力７０を受け、梁部材１８の他端部２２は他方の耐震壁１２から上向き力７２を受ける。これにより梁部材１８にせん断力が生じる。このとき、第１鉄筋４８は、両耐震壁１０、１２から圧縮力を受け、該圧縮力に抵抗し、第２鉄筋５０は、両耐震壁１０、１２から引張力を受け、該引張力に抵抗する。これにより、一方の耐震壁１０の他方の耐震壁１２に対する下方への動きを妨げて下向き力７０と上向き力７２とを低減させることができ、梁部材１８に生じる前記せん断力を小さくすることができる。   When each earthquake-resistant wall 10, 12 receives the first horizontal force and vibrates during an earthquake, one earthquake-resistant wall 10 moves in the vertical direction with respect to the other earthquake-resistant wall 12. As shown in FIG. 3, when one seismic wall 10 moves downward relative to the other seismic wall 12, one end 20 of the beam member 18 receives a downward force 70 from the one seismic wall 10, and the beam member The other end 22 of 18 receives an upward force 72 from the other seismic wall 12. Thereby, a shearing force is generated in the beam member 18. At this time, the first reinforcing bar 48 receives a compressive force from both the earthquake resistant walls 10 and 12 and resists the compressive force, and the second reinforcing bar 50 receives a tensile force from both the earthquake resistant walls 10 and 12 and receives the tensile force. resist. Accordingly, the downward force 70 and the upward force 72 can be reduced by preventing the downward movement of the one seismic wall 10 relative to the other seismic wall 12, and the shearing force generated in the beam member 18 can be reduced. it can.

また、一方の耐震壁１０が他方の耐震壁１２に対して上方へ動いているとき、梁部材１８の一端部２０は一方の耐震壁１０から上向き力（図示せず）を受け、梁部材１８の他端部２２は他方の耐震壁１２から下向き力（図示せず）を受ける。これにより梁部材１８にせん断力が生じる。このとき、第１鉄筋４８は、両耐震壁１０、１２から引張力を受け、該引張力に抵抗し、第２鉄筋５０は、両耐震壁１０、１２から圧縮力を受け、該圧縮力に抵抗する。これにより、一方の耐震壁１０の他方の耐震壁１２に対する上方への動きを妨げて前記上向き力と前記下向き力とを低減させることができ、梁部材１８に生じる前記せん断力を小さくすることができる。このため、梁部材１８のせん断破壊を防止することができる。   Further, when one seismic wall 10 moves upward relative to the other seismic wall 12, one end 20 of the beam member 18 receives an upward force (not shown) from the one seismic wall 10, and the beam member 18. The other end portion 22 receives a downward force (not shown) from the other earthquake-resistant wall 12. Thereby, a shearing force is generated in the beam member 18. At this time, the first reinforcing bar 48 receives a tensile force from both the earthquake resistant walls 10 and 12 and resists the tensile force, and the second reinforcing bar 50 receives a compressive force from both the earthquake resistant walls 10 and 12 and receives the compressive force. resist. Thereby, the upward movement of the one seismic wall 10 relative to the other seismic wall 12 can be prevented to reduce the upward force and the downward force, and the shearing force generated in the beam member 18 can be reduced. it can. For this reason, the shear failure of the beam member 18 can be prevented.

第１鉄筋４８及び第２鉄筋５０がそれぞれ第１シース６０及び第２シース６２により梁部材１８から隔てられているため、一方の耐震壁１０が他方の耐震壁１２に対して下方へ動いているとき、第１鉄筋４８が両耐震壁１０、１２から受けた圧縮力と、第２鉄筋５０が両耐震壁１０、１２から受けた引張力とが梁部材１８に伝わることはなく、前記圧縮力と前記引張力とが梁部材１８に伝わって該梁部材が損傷を受けることはない。また、一方の耐震壁１０が他方の耐震壁１２に対して上方へ動いているとき、第１鉄筋４８が両耐震壁１０、１２から受けた引張力と、第２鉄筋５０が両耐震壁１０、１２から受けた圧縮力とが梁部材１８に伝わることはなく、前記引張力と前記圧縮力とが梁部材１８に伝わって該梁部材が損傷を受けることはない。   Since the first rebar 48 and the second rebar 50 are separated from the beam member 18 by the first sheath 60 and the second sheath 62, respectively, one seismic wall 10 moves downward relative to the other seismic wall 12. At this time, the compressive force received by the first rebar 48 from the two seismic walls 10 and 12 and the tensile force received by the second rebar 50 from the both seismic walls 10 and 12 are not transmitted to the beam member 18, and the compressive force is The tensile force is not transmitted to the beam member 18 and the beam member is not damaged. Further, when one seismic wall 10 is moving upward with respect to the other seismic wall 12, the first rebar 48 receives the tensile force received from both seismic walls 10, 12, and the second rebar 50 has both seismic walls 10. , 12 is not transmitted to the beam member 18, and the tensile force and the compressive force are not transmitted to the beam member 18, and the beam member is not damaged.

梁部材１８の一端部２０の上端部分２６及び下端部分２８のそれぞれが一方の耐震壁１０から間隔を置かれ、梁部材１８の他端部２２の上端部分３８及び下端部分４０のそれぞれが他方の耐震壁１２から間隔を置かれているため、一方の耐震壁１０が他方の耐震壁１２に対して下方へ動いているときに一方の耐震壁１０及び他方の耐震壁１２がそれぞれ梁部材１８の一端部２０の上端部分２６及び他端部２２の下端部分４０を圧縮することはない。このため、梁部材１８は両耐震壁１０、１２から前記第１直線の方向の圧縮力を受け難く、前記第１直線の方向の圧縮力により梁部材１８の一端部２０の上端部分２６及び他端部２２の下端部分４０が破壊されたり、梁部材１８の全体にひび割れが生じたりすることを防ぐことができる。   Each of the upper end portion 26 and the lower end portion 28 of the one end portion 20 of the beam member 18 is spaced from one earthquake-resistant wall 10, and each of the upper end portion 38 and the lower end portion 40 of the other end portion 22 of the beam member 18 is the other end. Since one seismic wall 10 is moving downward with respect to the other seismic wall 12, the one seismic wall 10 and the other seismic wall 12 are each of the beam member 18. The upper end portion 26 of the one end portion 20 and the lower end portion 40 of the other end portion 22 are not compressed. For this reason, the beam member 18 is difficult to receive the compressive force in the direction of the first straight line from both the earthquake resistant walls 10 and 12, and the upper end portion 26 of the one end portion 20 of the beam member 18 and the like by the compressive force in the first straight line direction. It is possible to prevent the lower end portion 40 of the end portion 22 from being broken or the entire beam member 18 from being cracked.

また、一方の耐震壁１０が他方の耐震壁１２に対して上方へ動いているときに一方の耐震壁１０及び他方の耐震壁１２がそれぞれ梁部材１８の一端部２０の下端部分２８及び他端部２２の上端部分３８を圧縮することはない。このため、梁部材１８は両耐震壁１０、１２から前記第２直線の方向の圧縮力を受け難く、前記第２直線の方向の圧縮力により梁部材１８の一端部２０の下端部分２８及び他端部２２の上端部分３８が破壊されたり、梁部材１８の全体にひび割れが生じたりすることを防ぐことができる。   Further, when one earthquake-resistant wall 10 moves upward with respect to the other earthquake-resistant wall 12, the one earthquake-resistant wall 10 and the other earthquake-resistant wall 12 are respectively connected to the lower end portion 28 and the other end of the one end portion 20 of the beam member 18. The upper end portion 38 of the portion 22 is not compressed. For this reason, the beam member 18 is difficult to receive the compressive force in the direction of the second straight line from both the earthquake resistant walls 10, 12, and the lower end portion 28 of the one end portion 20 of the beam member 18 and others by the compressive force in the direction of the second straight line. It is possible to prevent the upper end portion 38 of the end portion 22 from being broken or the entire beam member 18 from being cracked.

梁部材１８の一端部２０の上端部分２６及び下端部分２８のそれぞれが一方の耐震壁１０から間隔を置かれ、梁部材１８の他端部２２の上端部分３８及び下端部分４０のそれぞれが他方の耐震壁１２から間隔を置かれているため、一方の耐震壁１０が他方の耐震壁１２に対して下方へ動いているとき、両耐震壁１０、１２は、梁部材１８による抵抗を受けることなく、より効果的に、第１鉄筋４８に圧縮力を、第２鉄筋５０に引張力をそれぞれ加えることができる。これにより、前記引張力により第２鉄筋５０を降伏させることに加えて、前記圧縮力により第１鉄筋４８を降伏させることによっても、地震時に生じた振動エネルギーを吸収することができる。   Each of the upper end portion 26 and the lower end portion 28 of the one end portion 20 of the beam member 18 is spaced from one earthquake-resistant wall 10, and each of the upper end portion 38 and the lower end portion 40 of the other end portion 22 of the beam member 18 is the other end. Since one seismic wall 10 is moving downward with respect to the other seismic wall 12 because it is spaced from the seismic wall 12, the two seismic walls 10, 12 are not subjected to resistance by the beam member 18. More effectively, a compressive force can be applied to the first rebar 48 and a tensile force can be applied to the second rebar 50, respectively. Thereby, in addition to yielding the second rebar 50 by the tensile force, the vibration energy generated during the earthquake can be absorbed also by yielding the first rebar 48 by the compressive force.

また、一方の耐震壁１０が他方の耐震壁１２に対して上方へ動いているとき、両耐震壁１０、１２は、梁部材１８による抵抗を受けることなく、より効果的に、第１鉄筋４８に引張力を、第２鉄筋５０に圧縮力をそれぞれ加えることができる。これにより、前記引張力により第１鉄筋４８を降伏させることに加えて、前記圧縮力により第２鉄筋５０を降伏させることによっても、地震時に生じた振動エネルギーを吸収することができる。このため、前記振動エネルギーの吸収効果を高めることができる。   In addition, when one earthquake-resistant wall 10 is moving upward with respect to the other earthquake-resistant wall 12, both the earthquake-resistant walls 10, 12 are not subjected to resistance by the beam member 18, and more effectively, the first reinforcing bar 48. A tensile force can be applied to the second reinforcing bar 50, and a compressive force can be applied to the second reinforcing bar 50, respectively. Thereby, in addition to yielding the first reinforcing bar 48 by the tensile force, the vibration energy generated during the earthquake can be absorbed also by yielding the second reinforcing bar 50 by the compressive force. For this reason, the absorption effect of the vibration energy can be enhanced.

一方の耐震壁１０が他方の耐震壁１２に対して上下方向に動くことにより、梁部材１８の一端部２０の上端部分２６及び下端部分２８のそれぞれと一方の耐震壁１０との間の間隔及び梁部材１８の他端部２２の上端部分３８及び下端部分４０のそれぞれと他方の耐震壁１２との間の間隔が変化する。このとき、第１緩衝材６６は、梁部材１８の一端部２０の上端部分２６又は下端部分２８と一方の耐震壁１０との間の間隔の変化に応じて変形し、一方の耐震壁１０が梁部材１８の一端部２０の上端部分２６又は下端部分２８に当たるのを阻止する。第２緩衝材６８は、梁部材１８の他端部２２の上端部分３８又は下端部分４０と他方の耐震壁１２との間の間隔の変化に応じて変形し、他方の耐震壁１２が梁部材１８の他端部２２の上端部分３８又は下端部分４０に当たるのを阻止する。   When one seismic wall 10 moves vertically with respect to the other seismic wall 12, the distance between the upper end portion 26 and the lower end portion 28 of the one end 20 of the beam member 18 and the one seismic wall 10, and The space | interval between each of the upper end part 38 and the lower end part 40 of the other end part 22 of the beam member 18 and the other earthquake-resistant wall 12 changes. At this time, the first shock absorber 66 is deformed according to a change in the distance between the upper end portion 26 or the lower end portion 28 of the one end portion 20 of the beam member 18 and the one earthquake-resistant wall 10, and the one earthquake-resistant wall 10 is The beam member 18 is prevented from hitting the upper end portion 26 or the lower end portion 28 of the one end portion 20 of the beam member 18. The second shock absorbing material 68 is deformed in accordance with a change in the distance between the upper end portion 38 or the lower end portion 40 of the other end portion 22 of the beam member 18 and the other earthquake-resistant wall 12, and the other earthquake-resistant wall 12 becomes the beam member. 18 against the upper end portion 38 or the lower end portion 40 of the other end 22.

第１鉄筋４８及び第２鉄筋５０は、それぞれ第１シース６０及び第２シース６２により覆われている図１に示した例に代え、それぞれ第１シース６０及び第２シース６２により覆われておらず、梁部材１８に付着しているものでもよい。一方の耐震壁１０と他方の耐震壁１２との間の間隔、すなわち梁１４のスパンは、建物１６の耐震性を損ねないようにするため、比較的短いものとすることが好ましく、例えば、１ｍから３ｍの範囲内とすることができる。梁１４のスパンは、１ｍから３ｍの範囲内である上記の例に代え、４ｍ以上でもよい。   The first reinforcing bar 48 and the second reinforcing bar 50 are covered with the first sheath 60 and the second sheath 62, respectively, instead of the example shown in FIG. 1 covered with the first sheath 60 and the second sheath 62, respectively. Alternatively, it may be attached to the beam member 18. The distance between one earthquake-resistant wall 10 and the other earthquake-resistant wall 12, that is, the span of the beam 14, is preferably relatively short so as not to impair the earthquake resistance of the building 16, for example, 1 m To 3 m. The span of the beam 14 may be 4 m or more instead of the above example in the range of 1 m to 3 m.

梁部材１８の内部に、複数の第１鉄筋４８と、複数の第２鉄筋５０とが配置されている図２に示した例に代え、梁部材１８の内部に、１本の第１鉄筋４８と、１本の第２鉄筋５０とが配置されていてもよい。また、梁部材１８の内部に少なくとも１本の第１鉄筋４８と少なくとも１本の第２鉄筋５０とが配置されている上記の例に代え、梁部材１８の内部に第１鉄筋４８と第２鉄筋５０とが配置されていなくてもよい。   Instead of the example shown in FIG. 2 in which a plurality of first reinforcing bars 48 and a plurality of second reinforcing bars 50 are arranged inside the beam member 18, one first reinforcing bar 48 is provided inside the beam member 18. In addition, one second reinforcing bar 50 may be disposed. Further, instead of the above example in which at least one first reinforcing bar 48 and at least one second reinforcing bar 50 are arranged inside the beam member 18, the first reinforcing bar 48 and the second reinforcing bar 48 are arranged inside the beam member 18. The reinforcing bars 50 may not be arranged.

図４に示す例では、梁１４は、梁部材１８の一端部２０の上端部分２６及び他端部２２の下端部分４０のそれぞれの内部に配置され、第１鉄筋４８を取り巻く第１スパイラル筋７４と、梁部材１８の一端部２０の下端部分２８及び他端部２２の上端部分３８のそれぞれの内部に配置され、第２鉄筋５０を取り巻く第２スパイラル筋７６とを有する。第１スパイラル筋７４は、梁部材１８の一端部２０の上端部分２６又は他端部２２の下端部分４０を補強し、第２スパイラル筋７６は、梁部材１８の一端部２０の下端部分２８又は他端部２２の上端部分３８を補強する。   In the example shown in FIG. 4, the beam 14 is disposed inside each of the upper end portion 26 of the one end portion 20 and the lower end portion 40 of the other end portion 22 of the beam member 18, and the first spiral reinforcement 74 surrounding the first rebar 48. And a second spiral bar 76 that is disposed inside each of the lower end part 28 of the one end 20 of the beam member 18 and the upper end part 38 of the other end 22 and surrounds the second reinforcing bar 50. The first spiral reinforcement 74 reinforces the upper end portion 26 of the one end portion 20 of the beam member 18 or the lower end portion 40 of the other end portion 22, and the second spiral reinforcement 76 is the lower end portion 28 of the one end portion 20 of the beam member 18 or The upper end portion 38 of the other end 22 is reinforced.

ところで、梁部材１８の一端部２０の上端部分２６が一方の耐震壁１０から間隔を置かれ、他端部２２の下端部分４０が他方の耐震壁１２から間隔を置かれているため、梁部材１８の一端部２０の上端部分２６と一方の耐震壁１０との間及び梁部材１８の他端部２２の下端部分４０と他方の耐震壁１２との間のそれぞれにおいて、第１鉄筋４８は、両耐震壁１０、１２から圧縮力を受けたとき、梁部材１８による拘束を受けることなく、変形しようとする。このため、梁部材１８の一端部２０の上端部分２６及び他端部２２の下端部分４０は損傷を受けやすい。第１スパイラル筋７４が梁部材１８の一端部２０の上端部分２６又は他端部２２の下端部分４０を補強することにより、梁部材１８の一端部２０の上端部分２６及び他端部２２の下端部分４０が損傷を受けるのを防ぐことができる。   By the way, since the upper end portion 26 of the one end portion 20 of the beam member 18 is spaced from one earthquake-resistant wall 10 and the lower end portion 40 of the other end portion 22 is spaced from the other earthquake-resistant wall 12, the beam member. 18 between the upper end portion 26 of the one end portion 20 of the 18 and the one seismic wall 10 and between the lower end portion 40 of the other end portion 22 of the beam member 18 and the other seismic wall 12, When a compressive force is received from both the earthquake resistant walls 10, 12, it tries to deform without being restrained by the beam member 18. For this reason, the upper end portion 26 of the one end portion 20 of the beam member 18 and the lower end portion 40 of the other end portion 22 are easily damaged. The first spiral bars 74 reinforce the upper end portion 26 of the one end portion 20 of the beam member 18 or the lower end portion 40 of the other end portion 22, so that the upper end portion 26 of the one end portion 20 and the lower end of the other end portion 22 of the beam member 18. The portion 40 can be prevented from being damaged.

また、梁部材１８の一端部２０の下端部分２８が一方の耐震壁１０から間隔を置かれ、他端部２２の上端部分３８が他方の耐震壁１２から間隔を置かれているため、梁部材１８の一端部２０の下端部分２８と一方の耐震壁１０との間及び梁部材１８の他端部２２の上端部分３８と他方の耐震壁１２との間のそれぞれにおいて、第２鉄筋５０は、両耐震壁１０、１２から圧縮力を受けたとき、梁部材１８による拘束を受けることなく、変形しようとする。このため、梁部材１８の一端部２０の下端部分２８及び他端部２２の上端部分３８は損傷を受けやすい。第２スパイラル筋７６が梁部材１８の一端部２０の下端部分２８又は他端部２２の上端部分３８を補強することにより、梁部材１８の一端部２０の下端部分２８及び他端部２２の上端部分３８が損傷を受けるのを防ぐことができる。   Further, since the lower end portion 28 of the one end portion 20 of the beam member 18 is spaced from the one earthquake-resistant wall 10 and the upper end portion 38 of the other end portion 22 is spaced from the other earthquake-resistant wall 12, the beam member.

When a compressive force is received from both the earthquake resistant walls 10, 12, it tries to deform without being restrained by the beam member 18. For this reason, the lower end portion 28 of the one end portion 20 of the beam member 18 and the upper end portion 38 of the other end portion 22 are easily damaged. The second spiral bar 76 reinforces the lower end portion 28 of the one end portion 20 of the beam member 18 or the upper end portion 38 of the other end portion 22, whereby the upper end of the lower end portion 28 and the other end portion 22 of the one end portion 20 of the beam member 18. The portion 38 can be prevented from being damaged.

梁部材１８の一端部２０の上端部分２６の端面３２及び下端部分２８の端面３４のそれぞれは、図１に示した例では、平面であるが、これに代え、図５に示す例では、曲面である。上端部分２６の端面３２は、中央部分２４の端面３０を含む平面と上端部分２６との間の間隔が中央部分２４から上方に向けて漸増するように湾曲しており、下端部分２８の端面３４は、中央部分２４の端面３０を含む平面と下端部分２８との間の間隔が中央部分２４から下方に向けて漸増するように湾曲している。   Each of the end surface 32 of the upper end portion 26 and the end surface 34 of the lower end portion 28 of the one end portion 20 of the beam member 18 is a flat surface in the example shown in FIG. 1, but instead, in the example shown in FIG. It is. The end surface 32 of the upper end portion 26 is curved so that the distance between the plane including the end surface 30 of the central portion 24 and the upper end portion 26 is gradually increased upward from the central portion 24, and the end surface 34 of the lower end portion 28 is. Are curved so that the distance between the plane including the end face 30 of the central portion 24 and the lower end portion 28 gradually increases downward from the central portion 24.

また、梁部材１８の他端部２２の上端部分３８の端面４４及び下端部分４０の端面４６のそれぞれは、図１に示した例では、平面であるが、これに代え、図５に示す例では、曲面である。上端部分３８の端面４４は、中央部分３６の端面４２を含む平面と上端部分３８との間の間隔が中央部分３６から上方に向けて漸増するように湾曲しており、下端部分４０の端面４６は、中央部分３６の端面４２を含む平面と下端部分４０との間の間隔が中央部分３６から下方に向けて漸増するように湾曲している。   Further, each of the end surface 44 of the upper end portion 38 and the end surface 46 of the lower end portion 40 of the other end portion 22 of the beam member 18 is a flat surface in the example shown in FIG. 1, but instead of this, the example shown in FIG. Then, it is a curved surface. The end surface 44 of the upper end portion 38 is curved so that the distance between the plane including the end surface 42 of the central portion 36 and the upper end portion 38 gradually increases upward from the central portion 36, and the end surface 46 of the lower end portion 40. Are curved so that the distance between the plane including the end face 42 of the central portion 36 and the lower end portion 40 gradually increases downward from the central portion 36.

Instead of the example, it is spaced inward in the first horizontal direction from the end surface 30 of the central portion 24 and is parallel to the end surface 30 of the central portion 24. The end surface 44 of the upper end portion 38 and the end surface 46 of the lower end portion 40 of the other end portion 22 of the beam member 18 are each replaced with the center portion instead of the example shown in FIG. 36 is spaced inwardly in the first horizontal direction from the end surface 42 of 36 and is parallel to the end surface 42 of the central portion 36.

なお、図１に示した例では、第１鉄筋４８の一端部５２は梁部材１８の一端部２０の外方において、第１鉄筋４８の他端部５４は梁部材１８の他端部２２の外方において、それぞれ前記第１水平方向に伸びているが、これに代え、図７に示すように、それぞれ前記第１直線の方向に伸びていてもよい。この場合、第１鉄筋４８は全体に一直線状である。また、図１に示した例では、第２鉄筋５０の一端部５６は梁部材１８の一端部２０の外方において、第２鉄筋５０の他端部５８は梁部材１８の他端部２２の外方において、それぞれ前記第１水平方向に伸びているが、これに代え、図７に示したように、それぞれ前記第２直線の方向に伸びていてもよい。この場合、第２鉄筋５０は全体に一直線状である。   In the example shown in FIG. 1, one end 52 of the first reinforcing bar 48 is outside the one end 20 of the beam member 18, and the other end 54 of the first reinforcing bar 48 is the other end 22 of the beam member 18. In the outward direction, each extends in the first horizontal direction, but instead, it may extend in the direction of the first straight line as shown in FIG. In this case, the first reinforcing bar 48 is linear in its entirety. In the example shown in FIG. 1, the one end 56 of the second reinforcing bar 50 is outside the one end 20 of the beam member 18, and the other end 58 of the second reinforcing bar 50 is the other end 22 of the beam member 18.

梁部材１８は、前記第１水平方向に間隔を置かれた一対の耐震壁１０、１２の間に配置されている図１に示した例に代え、前記第１水平方向に間隔を置かれた一対の柱（図示せず）の間に配置されていてもよい。この場合、梁部材１８の一端部２０は一方の柱に固定されており、梁部材１８の他端部２２は他方の柱に固定されている。梁部材１８の一端部２０の中央部分２４は前記一方の柱に結合されており、一端部２０の上端部分２６及び下端部分２８のそれぞれは前記一方の柱から間隔を置かれている。梁部材１８の他端部２２の中央部分３６は前記他方の柱に結合されており、他端部２２の上端部分３８及び下端部分４０のそれぞれは前記他方の柱から間隔を置かれている。   The beam member 18 is spaced apart in the first horizontal direction instead of the example shown in FIG. 1 arranged between the pair of seismic walls 10, 12 spaced in the first horizontal direction. You may arrange | position between a pair of pillars (not shown). In this case, one end 20 of the beam member 18 is fixed to one column, and the other end 22 of the beam member 18 is fixed to the other column. A central portion 24 of one end 20 of the beam member 18 is coupled to the one column, and each of the upper end portion 26 and the lower end portion 28 of the one end portion 20 is spaced from the one column. A central portion 36 of the other end portion 22 of the beam member 18 is coupled to the other column, and an upper end portion 38 and a lower end portion 40 of the other end portion 22 are spaced from the other column.

梁部材１８の一端部２０の上端部分２６及び下端部分２８のそれぞれが前記一方の柱から間隔を置かれ、梁部材１８の他端部２２の上端部分３８及び下端部分４０のそれぞれが前記他方の柱から間隔を置かれているため、地震時に各柱が前記第１水平方向の力を受けて前記一方の柱が前記他方の柱に対して下方へ動いているときに前記一方の柱及び前記他方の柱がそれぞれ梁部材１８の一端部２０の上端部分２６及び他端部２２の下端部分４０を圧縮することはない。これにより、梁部材１８の一端部２０の上端部分２６及び他端部２２の下端部分４０が破壊されたり、梁部材１８の全体にひび割れが生じたりすることを防ぐことができる。   Each of the upper end portion 26 and the lower end portion 28 of the one end portion 20 of the beam member 18 is spaced from the one column, and the upper end portion 38 and the lower end portion 40 of the other end portion 22 of the beam member 18 are respectively the other end. Since the columns are spaced from each other, each column receives the first horizontal force during an earthquake, and the one column and the one column move when the one column moves downward relative to the other column. The other column does not compress the upper end portion 26 of the one end portion 20 of the beam member 18 and the lower end portion 40 of the other end portion 22 respectively. Thereby, it can prevent that the upper end part 26 of the one end part 20 of the beam member 18 and the lower end part 40 of the other end part 22 are destroyed, or that the whole beam member 18 is cracked.

また、地震時に各柱が前記第１水平方向の力を受けて前記一方の柱が前記他方の柱に対して上方へ動いているときに前記一方の柱及び前記他方の柱がそれぞれ梁部材１８の一端部２０の下端部分２８及び他端部２２の上端部分３８を圧縮することはない。これにより、梁部材１８の一端部２０の下端部分２８及び他端部２２の上端部分３８が破壊されたり、梁部材１８の全体にひび割れが生じたりすることを防ぐことができる。   In addition, when each column receives the first horizontal force during an earthquake and the one column moves upward relative to the other column, the one column and the other column are respectively beam members 18. The lower end portion 28 of the one end portion 20 and the upper end portion 38 of the other end portion 22 are not compressed. Thereby, it can prevent that the lower end part 28 of the one end part 20 of the beam member 18 and the upper end part 38 of the other end part 22 are destroyed, or that the whole beam member 18 is cracked.

You may arrange | position between a seismic wall and a pillar (not shown). In this case, one end 20 of the beam member 18 is fixed to the earthquake-resistant wall, and the other end 22 of the beam member 18 is fixed to the column. A central portion 24 of one end 20 of the beam member 18 is coupled to the earthquake resistant wall, and each of the upper end portion 26 and the lower end portion 28 of the one end portion 20 is spaced from the earthquake resistant wall. A central portion 36 of the other end portion 22 of the beam member 18 is coupled to the column, and an upper end portion 38 and a lower end portion 40 of the other end portion 22 are spaced from the column.

梁部材１８の一端部２０の上端部分２６及び下端部分２８のそれぞれが前記耐震壁から間隔を置かれ、梁部材１８の他端部２２の上端部分３８及び下端部分４０のそれぞれが前記柱から間隔を置かれているため、地震時に前記耐震壁及び前記柱のそれぞれが前記第１水平方向の力を受けて前記耐震壁が前記柱に対して下方へ動いているときに前記耐震壁及び前記柱がそれぞれ梁部材１８の一端部２０の上端部分２６及び他端部２２の下端部分４０を圧縮することはない。これにより、梁部材１８の一端部２０の上端部分２６及び他端部２２の下端部分４０が破壊されたり、梁部材１８の全体にひび割れが生じたりすることを防ぐことができる。   Each of the upper end portion 26 and the lower end portion 28 of the one end portion 20 of the beam member 18 is spaced from the earthquake-resistant wall, and the upper end portion 38 and the lower end portion 40 of the other end portion 22 of the beam member 18 are spaced from the column. Therefore, when the earthquake-resistant wall and the column receive the first horizontal force during an earthquake and the earthquake-resistant wall is moving downward with respect to the column, the earthquake-resistant wall and the column are arranged. However, the upper end portion 26 of the one end portion 20 and the lower end portion 40 of the other end portion 22 of the beam member 18 are not compressed. Thereby, it can prevent that the upper end part 26 of the one end part 20 of the beam member 18 and the lower end part 40 of the other end part 22 are destroyed, or that the whole beam member 18 is cracked.

また、地震時に前記耐震壁及び前記柱のそれぞれが前記第１水平方向の力を受けて前記耐震壁が前記柱に対して上方へ動いているときに前記耐震壁及び前記柱がそれぞれ梁部材１８の一端部２０の下端部分２８及び他端部２２の上端部分３８を圧縮することはない。これにより、梁部材１８の一端部２０の下端部分２８及び他端部２２の上端部分３８が破壊されたり、梁部材１８の全体にひび割れが生じたりすることを防ぐことができる。   In addition, when the earthquake-resistant wall and the column receive the first horizontal force and the earthquake-resistant wall is moving upward with respect to the column during the earthquake, the earthquake-resistant wall and the column are each a beam member 18. The lower end portion 28 of the one end portion 20 and the upper end portion 38 of the other end portion 22 are not compressed. Thereby, it can prevent that the lower end part 28 of the one end part 20 of the beam member 18 and the upper end part 38 of the other end part 22 are destroyed, or that the whole beam member 18 is cracked.
