Description

特許法第３０条第２項適用 令和２年７月２０日発行のＤＶＤに収録Applicable to Article 30, Paragraph 2 of the Patent Act. Included in the DVD released on July 20, 2020.

本発明は、柱と梁とで構成される柱梁架構に利用可能な耐震補強構造であって、特に、柱と梁とで構成される柱梁架構の構面に対して耐震壁を接着接合により固定してなる耐震補強構造に関する。 The present invention relates to an earthquake-resistant reinforcement structure that can be used for a column-beam frame composed of columns and beams, and in particular to an earthquake-resistant reinforcement structure in which a seismic wall is fixed to the structural surface of a column-beam frame composed of columns and beams by adhesive bonding.

特許文献１には、柱（１）と梁（２）とで構成される柱梁架構で囲まれる構面に対して耐震壁（３）を接着接合により固定してなる耐震補強構造が示されている。この特許文献１の耐震補強構造では、耐震壁（３）は、面内方向（水平方向）に沿って並ぶ複数のパネルで構成されている。そして、パネル間の境界部に、パネル同士のずれを防止するためのパネル間ずれ防止部が設けられ、耐震壁の全周と柱梁架構との境界部に、耐震壁と柱や梁とのずれを防止するための柱梁ずれ防止部が設けられている。 Patent Document 1 shows an earthquake-resistant reinforcement structure in which an earthquake-resistant wall (3) is fixed by adhesive bonding to a structural surface surrounded by a column-beam structure composed of columns (1) and beams (2). In the earthquake-resistant reinforcement structure of Patent Document 1, the earthquake-resistant wall (3) is composed of multiple panels arranged along the in-plane direction (horizontal direction). Panel slip prevention parts are provided at the boundaries between the panels to prevent the panels from slipping, and column-beam slip prevention parts are provided at the boundaries between the entire periphery of the earthquake-resistant wall and the column-beam structure to prevent slippage between the earthquake-resistant wall and the columns or beams.

このような耐震補強構造では、耐震壁を複数のパネルで構成することで、プレキャストコンクリートで事前に成形した耐震壁を現場に運び易くなると共に、現場において開口部に耐震壁を設置し易くなる。また、パネルの境界部にパネル間ずれ防止部を設けることで、耐震壁を複数のパネルに分割しながらも耐震壁として必要な耐力を確保し易くなっている。 In this type of earthquake-resistant reinforcement structure, the earthquake-resistant wall is made up of multiple panels, which makes it easier to transport the earthquake-resistant wall, which has been precast with precast concrete, to the site and to install it in the opening at the site. In addition, by providing anti-slip sections between the panels at the boundaries between the panels, it becomes easier to ensure the necessary strength of the earthquake-resistant wall even when it is divided into multiple panels.

しかし、柱梁架構で囲まれる構面に耐震壁を接着接合により固定することで、地震が発生した際の梁の層間変形を防止できるものの、柱頭に応力が集中して柱頭にせん断ひび割れが発生する虞がある。 However, although adhesively bonding earthquake-resistant walls to the structural surfaces surrounded by the column-beam structure can prevent inter-layer deformation of the beams during an earthquake, there is a risk that stress will concentrate at the column heads, causing shear cracks to form in the column heads.

この実情に鑑み、本発明の主たる課題は、耐震壁を複数のパネルで構成して耐震壁を柱梁架構に設置し易くしながら耐震壁として十分な耐力を確保すると共に、柱頭のせん断ひび割れを抑制することが可能な耐震補強構造を提供する点にある。 In light of this situation, the main objective of the present invention is to provide an earthquake-resistant reinforcement structure in which the earthquake-resistant wall is constructed from multiple panels, making it easy to install the earthquake-resistant wall on a column-beam frame while ensuring sufficient strength as an earthquake-resistant wall and suppressing shear cracks at the column capitals.

本発明の第１特徴構成は、柱と梁とで構成される柱梁架構の構面に対して耐震壁を接着接合により固定してなる耐震補強構造であって、
前記耐震壁は、前記柱梁架構の面内方向に沿って並ぶ複数のパネルで構成され、
前記パネル間の境界部では、前記面内方向で前記境界部に沿った前記パネル同士のずれを防止するためのパネル間ずれ防止部が設けられ、
前記耐震壁と前記梁との境界部では、前記面内方向で前記境界部に沿った前記耐震壁と前記梁とのずれを防止するための耐震壁ずれ防止部が設けられ、
前記耐震壁と前記柱との境界部では、前記耐震壁と前記柱とが縁切りされ、
前記耐震壁ずれ防止部を構成するに、前記耐震壁の前記梁に対向する縁部が波形に形成されていると共に、前記耐震壁の縁部と前記梁との間に硬化性充填材が充填されている点にある。 The first characteristic configuration of the present invention is a seismic reinforcement structure in which a seismic wall is fixed to a structural surface of a column-beam frame composed of columns and beams by adhesive bonding,
The earthquake-resistant wall is composed of a plurality of panels arranged along the in-plane direction of the column-beam frame,
At the boundary between the panels, a panel slippage prevention portion is provided to prevent slippage between the panels along the boundary in the in-plane direction,
A seismic wall slippage prevention portion is provided at a boundary portion between the seismic wall and the beam to prevent slippage between the seismic wall and the beam along the boundary portion in the in-plane direction,
At the boundary between the earthquake-resistant wall and the column, the earthquake-resistant wall and the column are separated from each other ,
The earthquake-resistant wall slippage prevention portion is configured such that the edge of the earthquake-resistant wall facing the beam is formed in a corrugated shape, and a hardening filler material is filled between the edge of the earthquake-resistant wall and the beam .

本構成によれば、耐震壁を複数のパネルに分割してパネル間の境界部にパネル間ずれ防止部が設けられているため、耐震壁を複数のパネルに分割することで柱梁架構の構面に耐震壁を設置し易くしながら、パネル間ズレ防止部によりパネル同士のずれを防止することで、複数のパネルを一体的に機能させて耐震壁として必要な耐力を確保し易くなる。
そして、耐震壁と梁との境界部に設けられた耐震壁ずれ防止部により耐震壁と梁とのずれを防止することで、耐震壁の水平方向のせん断耐力にて上下の梁の層間変位（柱梁架構の変形）を防止して耐震性を向上できながら、耐震壁と柱との境界部の縁切りにより耐震壁と柱とのずれを許容することで、柱頭のせん断ひび割れを抑制することができる。 According to this configuration, the earthquake-resistant wall is divided into multiple panels and inter-panel slippage prevention sections are provided at the boundaries between the panels. By dividing the earthquake-resistant wall into multiple panels, it becomes easier to install the earthquake-resistant wall on the structural surface of the column-beam structure, while the inter-panel slippage prevention sections prevent slippage between the panels, making it easier to ensure the required strength of the earthquake-resistant wall by having the multiple panels function as a unit.
Furthermore, by preventing slippage between the earthquake-resistant wall and the beam using the earthquake-resistant wall slippage prevention section installed at the boundary between the earthquake-resistant wall and the beam, the horizontal shear strength of the earthquake-resistant wall can prevent inter-story displacement of the upper and lower beams (deformation of the column-beam structure), improving earthquake resistance, while by allowing slippage between the earthquake-resistant wall and the column by cutting the edge at the boundary between the earthquake-resistant wall and the column, shear cracks at the column capitals can be suppressed.

また、本構成によれば、耐震壁ずれ防止部において、耐震壁の縁部と梁との間に充填されている硬化性充填材に加えて、耐震壁の縁部が波状に形成されていることによって、耐震壁の縁部を直線状に形成した場合に比べて、耐震壁と梁とのずれをより好適に防止することができ、耐震壁の水平方向のせん断耐力を好適に発揮させて上下の梁の層間変位（柱梁架構の変形）を一層防止することができる。 Furthermore, according to this configuration, in the seismic wall slippage prevention section, in addition to the hardening filling material filled between the edge of the seismic wall and the beam, the edge of the seismic wall is formed in a wavy shape, which makes it possible to more effectively prevent slippage between the seismic wall and the beam compared to when the edge of the seismic wall is formed in a straight line, and allows the horizontal shear strength of the seismic wall to be optimally exerted, further preventing inter-story displacement of the upper and lower beams (deformation of the column-beam structure).

本発明の第２特徴構成は、柱と梁とで構成される柱梁架構の構面に対して耐震壁を接着接合により固定してなる耐震補強構造であって、
前記耐震壁は、前記柱梁架構の面内方向に沿って並ぶ複数のパネルで構成され、
前記パネル間の境界部では、前記面内方向で前記境界部に沿った前記パネル同士のずれを防止するためのパネル間ずれ防止部が設けられ、
前記耐震壁と前記梁との境界部では、前記面内方向で前記境界部に沿った前記耐震壁と前記梁とのずれを防止するための耐震壁ずれ防止部が設けられ、
前記耐震壁と前記柱との境界部では、前記耐震壁と前記柱とが縁切りされ、
前記パネル間ずれ防止部を構成するに、隣接する一対の前記パネルの相対向する縁部が互いに嵌り合う波型に形成されていると共に、一対の前記パネルの相対向する前記縁部の間に硬化性充填材が充填されている点にある。 The second characteristic configuration of the present invention is a seismic reinforcement structure in which a seismic wall is fixed to a structural surface of a column-beam frame composed of columns and beams by adhesive bonding,
The earthquake-resistant wall is composed of a plurality of panels arranged along the in-plane direction of the column-beam frame,
At the boundary between the panels, a panel slippage prevention portion is provided to prevent slippage between the panels along the boundary in the in-plane direction,
A seismic wall slippage prevention portion is provided at a boundary portion between the seismic wall and the beam to prevent slippage between the seismic wall and the beam along the boundary portion in the in-plane direction,
At the boundary between the earthquake-resistant wall and the column, the earthquake-resistant wall and the column are separated from each other,
The inter-panel slippage prevention portion is configured in such a way that the opposing edges of a pair of adjacent panels are formed into a corrugated shape that fits into each other, and a hardening filler is filled between the opposing edges of the pair of panels.

本構成によれば、耐震壁を複数のパネルに分割してパネル間の境界部にパネル間ずれ防止部が設けられているため、耐震壁を複数のパネルに分割することで柱梁架構の構面に耐震壁を設置し易くしながら、パネル間ズレ防止部によりパネル同士のずれを防止することで、複数のパネルを一体的に機能させて耐震壁として必要な耐力を確保し易くなる。
そして、耐震壁と梁との境界部に設けられた耐震壁ずれ防止部により耐震壁と梁とのずれを防止することで、耐震壁の水平方向のせん断耐力にて上下の梁の層間変位（柱梁架構の変形）を防止して耐震性を向上できながら、耐震壁と柱との境界部の縁切りにより耐震壁と柱とのずれを許容することで、柱頭のせん断ひび割れを抑制することができる。
また、本構成によれば、パネル間ずれ防止部において、一対のパネルの相対向する縁部の間に充填されている硬化性充填材に加えて、一対のパネルの縁部が波状に形成されていることによって、パネル同士のずれをより好適に防止することができる。しかも、一対のパネルの波状の縁部が互いに嵌り合っているため、パネル同士のずれを一層強力に防止することができる。よって、複数のパネルを更に一体的に機能させて耐震壁として必要な耐力を更に確保し易くなる。 According to this configuration, the earthquake-resistant wall is divided into multiple panels and inter-panel slippage prevention sections are provided at the boundaries between the panels. By dividing the earthquake-resistant wall into multiple panels, it becomes easier to install the earthquake-resistant wall on the structural surface of the column-beam structure, while the inter-panel slippage prevention sections prevent slippage between the panels, making it easier to ensure the required strength of the earthquake-resistant wall by having the multiple panels function as a unit.
Furthermore, by preventing slippage between the earthquake-resistant wall and the beam using the earthquake-resistant wall slippage prevention section installed at the boundary between the earthquake-resistant wall and the beam, the horizontal shear strength of the earthquake-resistant wall can prevent inter-story displacement of the upper and lower beams (deformation of the column-beam structure), improving earthquake resistance, while by allowing slippage between the earthquake-resistant wall and the column by cutting the edge at the boundary between the earthquake-resistant wall and the column, shear cracks at the column capitals can be suppressed.
In addition, according to this configuration, in the inter-panel slippage prevention portion, in addition to the hardening filler filled between the opposing edges of the pair of panels, the edges of the pair of panels are formed in a wavy shape, so that the panels can be more effectively prevented from slipping apart. Moreover, since the wavy edges of the pair of panels fit together, the panels can be more effectively prevented from slipping apart. This makes it easier to ensure the necessary strength of the earthquake-resistant wall by making the multiple panels function more integrally.

本発明の第３特徴構成は、前記耐震壁は、前記梁に対向する縁部を長辺とする横長形状に構成されている点にある。 A third characteristic feature of the present invention is that the earthquake-resistant wall is formed in a horizontally elongated shape with the edge portion facing the beam as the long side.

本構成によれば、耐震壁を、水平方向のせん断耐力を得るのに有利な横長形状とすることで、耐震壁と上下の梁の間に介在する耐震壁ずれ防止部を、水平方向のせん断力に対して効率良く抵抗させることができる。 With this configuration, the earthquake-resistant wall has a horizontally elongated shape that is advantageous for obtaining horizontal shear strength, and the earthquake-resistant wall slip prevention parts interposed between the earthquake-resistant wall and the upper and lower beams can efficiently resist horizontal shear forces.

本発明の第４特徴構成は、前記複数のパネルは、前記耐震壁の長辺方向に沿って並ぶ状態で設けられている点にある。 A fourth characteristic feature of the present invention is that the plurality of panels are arranged side by side along the longer side direction of the earthquake-resistant wall.

本構成によれば、複数のパネルを、耐震壁の長辺方向に沿って並ぶ状態で設けることで、耐震壁の長辺方向に沿うパネルの短辺を長くすると共に耐震壁の短辺方向に沿うパネルの長辺を短くすることができる。よって、各パネルの形状を正方形状に近づけることができ、現場への運搬性や現場での施工性を向上させることができる。 According to this configuration, by arranging multiple panels in a line along the long side of the earthquake-resistant wall, it is possible to lengthen the short side of the panel along the long side of the earthquake-resistant wall and shorten the long side of the panel along the short side of the earthquake-resistant wall. This allows the shape of each panel to approach a square shape, improving transportability to the site and ease of construction on site.

本発明の第５特徴構成は、前記複数のパネルの夫々が、ＳＦＲＣ造パネルである点にある。 A fifth characteristic feature of the present invention is that each of the plurality of panels is a SFRC panel.

本構成によれば、パネルを、ＳＦＲＣ（Ｓｔｅｅｌ Ｆｉｂｅｒ Ｒｅｉｎｆｏｒｃｅｄ Ｃｏｎｃｒｅｔｅ：鋼繊維補強コンクリート）造とすることで、高靭性で高強度なパネルを構成して耐震壁の耐力を向上させることができる。 According to this configuration, by constructing the panels out of SFRC (Steel Fiber Reinforced Concrete), it is possible to construct high-toughness, high-strength panels and improve the strength of the earthquake-resistant walls.

本発明の実施形態について図面に基づいて説明する。
図１に示す耐震補強構造１は、柱２と梁３とで構成される柱梁架構４の構面５に対して耐震壁６が接着接合により固定されている。説明を加えると、耐震補強構造１は、柱梁架構４を備えた建築物に対し、耐震補強のための改修工事を実施して、柱梁架構４の構面５に耐震壁６を接着接合した構造である。 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.
In the earthquake-resistant reinforcement structure 1 shown in Fig. 1, a seismic wall 6 is fixed by adhesive bonding to a structural surface 5 of a column-beam frame 4 composed of a column 2 and a beam 3. To explain further, the earthquake-resistant reinforcement structure 1 is a structure in which a building equipped with a column-beam frame 4 is retrofitted for earthquake reinforcement and the seismic wall 6 is adhesively bonded to the structural surface 5 of the column-beam frame 4.

図１に示すように、柱梁架構４は、左側柱７と右側柱８との一対の柱２と、上側梁９と下側梁１０との一対の梁３とで構成されており、これらにより囲まれる矩形状の設置空間（構面５）に耐震壁６が設置されている。図示は省略するが、上側梁９や下側梁１０はスラブと一体的に構成されている。なお、一対の柱２が並ぶ方向を左右方向Ｘとし、一対の梁３が並ぶ方向を上下方向Ｙとしている。 As shown in Figure 1, the column-beam structure 4 is composed of a pair of columns 2, a left column 7 and a right column 8, and a pair of beams 3, an upper beam 9 and a lower beam 10, and a seismic wall 6 is installed in the rectangular installation space (structural surface 5) enclosed by these. Although not shown in the figure, the upper beam 9 and the lower beam 10 are integrally formed with the slab. The direction in which the pair of columns 2 are lined up is the left-right direction X, and the direction in which the pair of beams 3 are lined up is the up-down direction Y.

耐震壁６は、梁３に対向する縁部（梁側縁部１７と称する）を長辺とする横長形状に形成されている。つまり、一対の柱２の間隔は、一対の梁３の間隔より広くなっており、設置空間は、上下方向Ｙに比べて左右方向Ｘが長い横長形状となっている。そのため、この設置空間に設置される耐震壁６も、上下方向Ｙに比べて左右方向Ｘが長い横長形状となっている。 The earthquake-resistant wall 6 is formed in a horizontally elongated shape with the edge (referred to as the beam side edge 17) facing the beam 3 as the long side. In other words, the distance between the pair of columns 2 is wider than the distance between the pair of beams 3, and the installation space is horizontally elongated in a direction X that is longer in a direction Y ...

耐震壁６は、柱梁架構４の面内方向に沿って並ぶ複数のパネル１１で構成されている。本実施形態では、複数のパネル１１は、耐震壁６の長辺方向に沿って並ぶ状態で設けられている。つまり、本実施形態では、上述の如く、耐震壁６は左右方向Ｘに長い横長形状に形成されており、複数のパネル１１は、左右方向Ｘに沿って並ぶ状態で設けられている。また、複数のパネル１１の夫々は、左右方向Ｘに比べて上下方向Ｙが長い縦長形状に形成されている。本実施形態では、耐震壁６は３枚のパネル１１で構成されており、これらの３枚のパネル１１について、図１において左側Ｘ１にあるパネル１１から順に、第１パネル１１Ａ、第２パネル１１Ｂ、第３パネル１１Ｃと称する場合がある。複数のパネル１１の夫々は、鉄筋ではなく多数の鋼繊維をコンクリートに混入して補強された鋼繊維補強コンクリートからなる高靭性で高強度なＳＦＲＣ造パネルである。 The earthquake-resistant wall 6 is composed of a plurality of panels 11 arranged along the in-plane direction of the column-beam frame 4. In this embodiment, the plurality of panels 11 are arranged along the long side direction of the earthquake-resistant wall 6. That is, in this embodiment, as described above, the earthquake-resistant wall 6 is formed in a horizontally elongated shape that is long in the left-right direction X, and the plurality of panels 11 are arranged in a state of being arranged along the left-right direction X. Also, each of the plurality of panels 11 is formed in a vertically elongated shape that is longer in the up-down direction Y than in the left-right direction X. In this embodiment, the earthquake-resistant wall 6 is composed of three panels 11, and these three panels 11 may be referred to as the first panel 11A, the second panel 11B, and the third panel 11C in order from the panel 11 on the left side X1 in FIG. 1. Each of the plurality of panels 11 is a high-toughness, high-strength SFRC panel made of steel fiber reinforced concrete reinforced by mixing a large number of steel fibers into concrete instead of reinforcing bars.

パネル１１間の境界部では、面内方向で境界部に沿ったパネル１１同士のずれを防止するためのパネル間ずれ防止部１３が設けられている。本実施形態では、パネル間ずれ防止部１３は、パネル１１同士の上下方向Ｙのずれを防止するように構成されている。パネル間ずれ防止部１３を構成するに、隣接する一対のパネル１１の相対向する縁部であるパネル側縁部１４が互いに嵌り合う波型に形成されていると共に、一対のパネル１１の相対向するパネル側縁部１４の間にグラウト材（無収縮モルタル）等の硬化性充填材１５が充填されている。 At the boundary between the panels 11, a panel slippage prevention part 13 is provided to prevent the panels 11 from slipping along the boundary in the in-plane direction. In this embodiment, the panel slippage prevention part 13 is configured to prevent the panels 11 from slipping in the up-down direction Y. To configure the panel slippage prevention part 13, the panel side edge parts 14, which are the opposing edges of a pair of adjacent panels 11, are formed into a wave shape that fits into each other, and a hardening filler 15 such as grout material (non-shrink mortar) is filled between the opposing panel side edge parts 14 of the pair of panels 11.

説明を加えると、図１及び図２に示すように、第１パネル１１Ａの右側Ｘ２の縁部と第２パネル１１Ｂの左側Ｘ１の縁部が、相対向するパネル側縁部１４となっており、これら第１パネル１１Ａの右側Ｘ２の縁部と第２パネル１１Ｂの左側Ｘ１の縁部とが互いに嵌り合う波型に形成されている。そして、第１パネル１１Ａの右側Ｘ２の縁部と第２パネル１１Ｂの左側Ｘ１の縁部との間に、硬化性充填材１５が充填されており、第１パネル１１Ａと第２パネル１１Ｂとが接着接合されている。「一対のパネル１１の相対向する縁部が互いに嵌り合う」とは、左側Ｘ１のパネル１１における右側Ｘ２の縁部の頂点が、右側Ｘ２のパネル１１における左側Ｘ１の縁部の頂点より右側Ｘ２に位置しており、上下方向Ｙに沿う上下方向視で一対のパネル１１の縁部が互いに重複する部分を有していることを意味している。 To explain further, as shown in Figs. 1 and 2, the edge of the right side X2 of the first panel 11A and the edge of the left side X1 of the second panel 11B form opposing panel side edges 14, and the edge of the right side X2 of the first panel 11A and the edge of the left side X1 of the second panel 11B are formed in a wave shape that fits together. A hardening filler 15 is filled between the edge of the right side X2 of the first panel 11A and the edge of the left side X1 of the second panel 11B, and the first panel 11A and the second panel 11B are adhesively joined. "The opposing edges of the pair of panels 11 fit together" means that the apex of the edge of the right side X2 of the left side X1 panel 11 is located to the right X2 of the apex of the edge of the left side X1 of the right side X2 panel 11, and the edges of the pair of panels 11 have overlapping portions when viewed in the vertical direction Y.

また、同様に、図１に示すように、第２パネル１１Ｂの右側Ｘ２の縁部と第３パネル１１Ｃの左側Ｘ１の縁部が、相対向するパネル側縁部１４となっており、これら第２パネル１１Ｂの右側Ｘ２の縁部と第３パネル１１Ｃの左側Ｘ１の縁部とが互いに嵌り合う波型に形成されている。そして、第２パネル１１Ｂの右側Ｘ２の縁部と第３パネル１１Ｃの左側Ｘ１の縁部との間に、硬化性充填材１５が充填されており、第２パネル１１Ｂと第３パネル１１Ｃとが接着接合されている。 Similarly, as shown in FIG. 1, the right edge X2 of the second panel 11B and the left edge X1 of the third panel 11C form opposing panel side edges 14, and the right edge X2 of the second panel 11B and the left edge X1 of the third panel 11C are formed into a corrugated shape that fits together. A hardening filler 15 is filled between the right edge X2 of the second panel 11B and the left edge X1 of the third panel 11C, and the second panel 11B and the third panel 11C are adhesively joined together.

耐震壁６と梁３との境界部では、面内方向で境界部に沿った耐震壁６と梁３とのずれを防止するための耐震壁ずれ防止部１６が設けられている。本実施形態では、耐震壁ずれ防止部１６は、耐震壁６と梁３との左右方向Ｘのずれを防止するように構成されている。耐震壁ずれ防止部１６を構成するに、耐震壁６の梁３に対向する縁部である梁側縁部１７が波形に形成されていると共に、耐震壁６の縁部と梁３との間にグラウト等の硬化性充填材１５が充填されている。 At the boundary between the earthquake-resistant wall 6 and the beam 3, an earthquake-resistant wall slippage prevention part 16 is provided to prevent slippage between the earthquake-resistant wall 6 and the beam 3 along the boundary in the in-plane direction. In this embodiment, the earthquake-resistant wall slippage prevention part 16 is configured to prevent slippage between the earthquake-resistant wall 6 and the beam 3 in the left-right direction X. To configure the earthquake-resistant wall slippage prevention part 16, the beam side edge part 17, which is the edge part of the earthquake-resistant wall 6 facing the beam 3, is formed in a corrugated shape, and a hardening filler 15 such as grout is filled between the edge part of the earthquake-resistant wall 6 and the beam 3.

説明を加えると、図１及び図３に示すように、耐震壁６の上側Ｙ１の縁部（第１パネル１１Ａの上側Ｙ１の縁部、第２パネル１１Ｂの上側Ｙ１の縁部、及び第３パネル１１Ｃの上側Ｙ１の縁部）が、梁側縁部１７となっており、波型に形成されている。そして、耐震壁６の上側Ｙ１の梁側縁部１７と上側梁９との間に硬化性充填材１５が充填されており、耐震壁６と上側梁９とが接着接合されている。 To explain further, as shown in Figures 1 and 3, the edges of the upper side Y1 of the earthquake-resistant wall 6 (the edge of the upper side Y1 of the first panel 11A, the edge of the upper side Y1 of the second panel 11B, and the edge of the upper side Y1 of the third panel 11C) are beam side edges 17 and are formed in a wave shape. A hardening filler 15 is filled between the beam side edges 17 of the upper side Y1 of the earthquake-resistant wall 6 and the upper beam 9, and the earthquake-resistant wall 6 and the upper beam 9 are adhesively joined.

また、同様に、図１に示すように、耐震壁６の下側Ｙ２の縁部（第１パネル１１Ａの下側Ｙ２の縁部、第２パネル１１Ｂの下側Ｙ２の縁部、及び第３パネル１１Ｃの下側Ｙ２の縁部）が、梁側縁部１７となっており、波型に形成されている。そして、耐震壁６の下側Ｙ２の梁側縁部１７と下側梁１０との間に硬化性充填材１５が充填されており、耐震壁６と下側梁１０とが接着接合されている。 Similarly, as shown in FIG. 1, the edges of the lower side Y2 of the earthquake-resistant wall 6 (the edges of the lower side Y2 of the first panel 11A, the edges of the lower side Y2 of the second panel 11B, and the edges of the lower side Y2 of the third panel 11C) are beam side edges 17 and are formed in a corrugated shape. A hardening filler 15 is filled between the beam side edges 17 of the lower side Y2 of the earthquake-resistant wall 6 and the lower beam 10, and the earthquake-resistant wall 6 and the lower beam 10 are adhesively joined.

耐震壁６と柱２との境界部では、耐震壁６と柱２とが縁切りされており、面内方向で境界部に沿った耐震壁６と柱２とのずれを許容するための耐震壁非ずれ防止部１８が設けられている。本実施形態では、耐震壁非ずれ防止部１８は、耐震壁６と柱２との上下方向Ｙのずれを許容するように構成されている。耐震壁非ずれ防止部１８を構成するに、耐震壁６の縁部と柱２との間に硬化性充填材１５が充填されているが、耐震壁６の柱２に対向する縁部である柱側縁部１９が直線状に形成されていると共に、柱２と硬化性充填材１５とが相対的に上下方向Ｙに移動可能なように、柱２における耐震壁６が存在する側の面にシート材２０が備えられている。 At the boundary between the earthquake-resistant wall 6 and the column 2, the earthquake-resistant wall 6 and the column 2 are cut off, and an earthquake-resistant wall non-slip prevention part 18 is provided to allow the earthquake-resistant wall 6 and the column 2 to slip along the boundary in the in-plane direction. In this embodiment, the earthquake-resistant wall non-slip prevention part 18 is configured to allow the earthquake-resistant wall 6 and the column 2 to slip in the vertical direction Y. To configure the earthquake-resistant wall non-slip prevention part 18, a hardening filler 15 is filled between the edge of the earthquake-resistant wall 6 and the column 2, and the column side edge part 19, which is the edge of the earthquake-resistant wall 6 facing the column 2, is formed in a straight line, and a sheet material 20 is provided on the surface of the column 2 on the side where the earthquake-resistant wall 6 exists, so that the column 2 and the hardening filler 15 can move relatively in the vertical direction Y.

説明を加えると、図１及び図４に示すように、耐震壁６の左側Ｘ１の縁部（第１パネル１１Ａの左側Ｘ１の縁部）が、柱側縁部１９となっており、直線状に形成されている。そして、左側柱７の右側Ｘ２を向く面にシート材２０として養生テープが貼付された状態で、耐震壁６の柱側縁部１９と左側柱７との間に硬化性充填材１５が充填されている。そのため、耐震壁６と左側柱７との間は硬化性充填材１５で埋められているものの、耐震壁６と左側柱７とは接着接合されておらず互いに上下方向Ｙに移動可能となっている。 To explain further, as shown in Figures 1 and 4, the edge of the left side X1 of the earthquake-resistant wall 6 (the edge of the left side X1 of the first panel 11A) is the column side edge 19, which is formed in a straight line. Then, with masking tape applied as a sheet material 20 to the surface of the left-side column 7 facing the right side X2, hardening filler 15 is filled between the column side edge 19 of the earthquake-resistant wall 6 and the left-side column 7. Therefore, although the space between the earthquake-resistant wall 6 and the left-side column 7 is filled with hardening filler 15, the earthquake-resistant wall 6 and the left-side column 7 are not adhesively joined, and can move relative to each other in the vertical direction Y.

また、同様に、図１に示すように、耐震壁６の右側Ｘ２の縁部（第３パネル１１Ｃの右側Ｘ２の縁部）が、柱側縁部１９となっており直線状に形成されている。そして、右側柱８の左側Ｘ１を向く面にシート材２０として養生テープが貼付された状態で、耐震壁６の柱側縁部１９と右側柱８との間に硬化性充填材１５が充填されている。そのため、耐震壁６と右側柱８との間は硬化性充填材１５で埋められているものの、耐震壁６と右側柱８とは接着接合されておらず互いに上下方向Ｙに移動可能となっている。 Similarly, as shown in FIG. 1, the edge of the right side X2 of the earthquake-resistant wall 6 (the edge of the right side X2 of the third panel 11C) is formed in a straight line as the column side edge 19. Then, with masking tape applied as a sheet material 20 to the surface of the right-side column 8 facing the left side X1, hardening filler 15 is filled between the column side edge 19 of the earthquake-resistant wall 6 and the right-side column 8. Therefore, although the space between the earthquake-resistant wall 6 and the right-side column 8 is filled with hardening filler 15, the earthquake-resistant wall 6 and the right-side column 8 are not adhesively joined, and can move relative to each other in the vertical direction Y.
