Description

この発明は、柱と横架材とを両者の取り合い箇所以外の箇所で別途強固に一体化可能とする耐震補強金物、および、これを利用した耐震補強構造に関する。 The present invention relates to a seismic retrofitting metal fitting that enables the column and the horizontal member to be separately and firmly integrated at a place other than the joint portion between the two, and a seismic retrofitting structure using the same.

既設の建物の耐震性を高めるリフォーム工事の手法として、壁下地材を取り外した状態から、柱と横架材とで囲まれた空間内において、柱と横架材とをいわゆる柱頭柱脚金物で接続する手法がある。 As a method of remodeling work to improve the earthquake resistance of existing buildings, from the state where the wall base material is removed, in the space surrounded by the columns and the horizontal members, the columns and the horizontal members are made of so-called stigma pillar base hardware. There is a method to connect.

しかるに、前記空間内に備えられる筋交いは、多くの場合、柱と横架材との取り合い箇所に設置されて柱と横架材にそれぞれ止着された筋交い金物にその一端を止着される。このため、前記の柱頭柱脚金物の設置に先だって、かかる筋交い金物の取り外しを要することが少なくない。こうしたことから、こうしたリフォーム工事において、既設の筋交い金物を取り外すことなく、したがって、既設の筋交いの取付状態に影響を与えることなく、前記の柱頭柱脚金物の機能を備える耐震補強金物を設置できるようにすることが望まれるところであった。 However, in many cases, the brace provided in the space is fixed at one end to the brace hardware which is installed at the joint between the column and the horizontal member and is fixed to the column and the horizontal member, respectively. Therefore, it is often necessary to remove the brace hardware prior to the installation of the stigma column base hardware. Therefore, in such remodeling work, it is possible to install the seismic retrofitting hardware having the function of the stigma column base hardware without removing the existing brace hardware and therefore without affecting the mounting state of the existing brace. It was a place where it was desired to do.

建物の耐震性を高める装置ないし金物として、特許文献１及び２に示されるものがある。かかる装置ないし金物は、柱に取り付けられる部分と横架材に取り付けられる部分と持ち、柱と横架材との取り合い箇所の内側において両者の間に斜めに架け渡される構造となっている。しかるに、かかる装置ないし金物は、その全長及び取り付け角度の変更ができない構造となっている。このため、かかる装置ないし金物は、例えば、柱や横架材が二つの材を継ぎ合わせて構成されていてその継ぎ目が柱と横架材との取り合い箇所近傍に位置されている場合にこの継ぎ目に設置される接続金物を避けるようにした取り付けを行い難い。あるいはまた、かかる装置ないし金物は、横架材に対するアンカーボルトが柱と横架材との取り合い箇所近傍に位置されている場合にこのアンカーボルトを避けた取り付けを行い難い。 As a device or hardware for enhancing the earthquake resistance of a building, there are those shown in Patent Documents 1 and 2. Such a device or hardware has a part to be attached to a pillar and a part to be attached to a horizontal member, and has a structure in which the device or hardware is diagonally bridged between the two inside the joint portion between the pillar and the horizontal member. However, such a device or hardware has a structure in which the total length and the mounting angle cannot be changed. Therefore, such a device or hardware is, for example, when a column or a horizontal member is formed by joining two members and the joint is located near a joint between the column and the horizontal member. It is difficult to install so as to avoid the connection hardware installed in. Alternatively, it is difficult to attach such a device or hardware to avoid the anchor bolts when the anchor bolts for the horizontal members are located near the joints between the columns and the horizontal members.

この発明が解決しようとする主たる問題点は、既存の建物の耐震性を高めるリフォーム工事において、既設の筋交い金物を取り外すことなく、したがってまた、既設の筋交いの取り付け状態に影響を与えることなく、柱と横架材とを両者の取り合い箇所以外の箇所で、容易且つ適切に、別途強固に一体化できるようにする点にある。 The main problem to be solved by the present invention is that in the remodeling work to improve the seismic resistance of the existing building, the pillars without removing the existing brace hardware and therefore also without affecting the installation state of the existing brace. The point is that the and the horizontal member can be easily and appropriately and firmly integrated separately at a place other than the place where the two are connected.

前記課題を達成するために、この発明にあっては、第一の観点から、耐震補強金物を、柱における前記柱と横架材とで囲まれた空間に面した側面に対する柱側取付部と、
前記横架材における前記空間に面した側面に対する横架材側取付部と、
前記柱側取付部と前記横架材側取付部とをつなぐ軸体とを備えると共に、
前記柱側取付部は、一面を取付面とした基板と、前記基板の他面側に形成された軸受け部とを有し、前記柱側取付部を、前記軸受け部をもって前記軸体の一端部に水平軸をもって回動可能に組み合わせており、
前記横架材側取付部は、一面を取付面とした基板と、前記基板の他面側に形成された軸受け部とを有し、前記横架材側取付部を、前記軸受け部をもって前記軸体の他端部に水平軸をもって回動可能に組み合わせてなり、
前記軸体を、前記柱側取付部に組み合わされる柱側軸部と前記横架材側取付部に組み合わされる横架材側軸部とを、両軸部間にあって両軸部にそれぞれネジ付けられるナット体によって連結させてなる、ものとした。 In order to achieve the above object, in the present invention, from the first viewpoint, the seismic retrofitting hardware is attached to the column side mounting portion with respect to the side surface of the column facing the space surrounded by the column and the horizontal member. ,
The horizontal lumber side mounting portion with respect to the side surface of the horizontal lumber facing the space, and
A shaft body that connects the pillar-side mounting portion and the horizontal member-side mounting portion is provided, and the shaft body is provided.
The pillar-side mounting portion has a substrate having one surface as a mounting surface and a bearing portion formed on the other surface side of the substrate, and the pillar-side mounting portion has the bearing portion at one end of the shaft body. It is rotatably combined with a horizontal axis.
The horizontal member side mounting portion has a substrate having one surface as a mounting surface and a bearing portion formed on the other surface side of the substrate, and the horizontal member side mounting portion has the bearing portion as the shaft. It is rotatably combined with a horizontal axis at the other end of the body.
The pillar-side shaft portion to be combined with the pillar-side mounting portion and the horizontal member-side shaft portion to be combined with the horizontal member-side mounting portion of the shaft body are located between the two shaft portions and are screwed to both shaft portions. It was assumed that it was connected by a nut body.

かかる耐震補強金物は、柱側取付部と横架材側取付部とを軸体でつなぐ構成となっていることから、柱と横架材との取り合い箇所において、柱と横架材とで囲われた空間側に備え付けられる既設の筋交い金物の上方又は下方に前記柱側取付部を位置させ、かつ、既設の筋交い金物よりも前記空間の中央側に前記横架材側取付部を位置させ、かつ、前記軸体を既設の筋交い金物の斜め上方又は斜め下方に位置させるようにして、柱と横架材とを強固に一体化させることができる。すなわち、かかる耐震補強金物は、既設の筋交い金物をまたぐようにして既設の筋交い金物を取り外すことなく設置可能で、いわゆる柱頭柱脚金物としての機能を持つ。 Since the seismic reinforcement hardware has a structure in which the column-side mounting portion and the horizontal member-side mounting portion are connected by a shaft body, the column and the horizontal member are surrounded by the column and the horizontal member at the joints between the column and the horizontal member. The column side mounting portion is positioned above or below the existing brace hardware provided on the space side, and the cross member side mounting portion is positioned on the center side of the space with respect to the existing brace hardware. Moreover, the column and the horizontal member can be firmly integrated by locating the shaft body diagonally above or diagonally below the existing brace hardware. That is, the seismic retrofitting hardware can be installed without removing the existing bracing hardware so as to straddle the existing bracing hardware, and has a function as a so-called stigma column base hardware.

また、かかる耐震補強金物は、柱側取付部と軸体の一端部とを水平軸をもって回動可能に組み合わせ、かつ、横架材側取付部と軸体の他端部とを水平軸をもって回動可能に組み合わせる構成となっていることから、柱側取付部の取付面と軸体の軸線とがなす角度を自由に変えることができ、したがって、柱側取付部及び横架材側取付部を状況に応じてもっとも適切と考えられる取り付け位置に取り付けることができる。例えば、柱や横架材が二つの材を継ぎ合わせて構成されていてその継ぎ目が柱と横架材との取り合い箇所近傍に位置されている場合にこの継ぎ目に設置される接続金物を避けた柱側取付部及び横架材側取付部の取り付けを容易になすことができる。あるいはまた、横架材に対するアンカーボルトが柱と横架材との取り合い箇所近傍に位置されている場合にこのアンカーボルトを避けた横架材側取付部の取り付けを容易になすことができる。 Further, in such a seismic reinforcing metal fitting, the column side mounting portion and one end of the shaft body are rotatably combined with a horizontal axis, and the horizontal member side mounting portion and the other end of the shaft body are rotated with the horizontal axis. Since it is configured to be movable, the angle between the mounting surface of the column side mounting part and the axis of the shaft can be freely changed. Therefore, the pillar side mounting part and the horizontal member side mounting part can be freely changed. It can be mounted in the most appropriate mounting position depending on the situation. For example, when a column or horizontal member is composed of two members joined together and the joint is located near the joint between the column and the horizontal member, the connecting hardware installed at this joint is avoided. The pillar-side mounting portion and the horizontal member-side mounting portion can be easily mounted. Alternatively, when the anchor bolt for the horizontal member is located near the joint between the pillar and the horizontal member, the horizontal member side mounting portion avoiding the anchor bolt can be easily attached.

前記柱側軸部の前記軸体の一端部となる端部を、前記柱側取付部の前記軸受け部に軸支される水平軸にネジ付け、前記横架材側軸部の前記軸体の他端部となる端部を、前記横架材側取付部の前記軸受け部に軸支される水平軸にネジ付けるようにしておくことが、この発明の態様の一つとされる。 An end portion of the pillar-side shaft portion, which is one end of the shaft body, is screwed to a horizontal shaft pivotally supported by the bearing portion of the pillar-side mounting portion, and the shaft body of the horizontal member side shaft portion is screwed. One of the aspects of the present invention is to screw the end portion, which is the other end portion, to the horizontal shaft pivotally supported by the bearing portion of the horizontal member side mounting portion.

また、前記課題を達成するために、この発明にあっては、第二の観点から、耐震補強構造を、
前記耐震補強金物を構成する柱側取付部を、前記柱における前記柱と前記横架材とで囲まれた空間に面した側面であって既設の筋交い金物の上方又は下方に位置される箇所に止着させ、
かつ、前記耐震補強金物を構成する横架材側取付部を、前記横架材における前記空間に面した側面であって前記既設の筋交い金物よりも前記空間の中央側に位置される箇所に止着させると共に、
前記軸体を既設の筋交いの側方に位置させるようにしてなる、ものとした。 Further, in order to achieve the above object, in the present invention, a seismic retrofitting structure is provided from the second viewpoint.
The column-side mounting portion constituting the seismic retrofitting hardware is placed on the side surface of the column facing the space surrounded by the column and the horizontal member and located above or below the existing brace hardware. Stop,
Moreover, the horizontal member side mounting portion constituting the seismic retrofitting hardware is stopped at a position on the side surface of the horizontal member facing the space and located on the central side of the space with respect to the existing brace hardware. Along with dressing
The shaft body is positioned on the side of the existing brace.

この発明によれば、既存の建物の耐震性を高めるリフォーム工事において、既設の筋交い金物を取り外すことなく、したがってまた、既設の筋交いの取り付け状態に影響を与えることなく、柱と横架材とを両者の取り合い箇所以外の箇所で、容易且つ適切に、別途強固に一体化することができる。 According to the present invention, in the remodeling work for improving the seismic resistance of an existing building, the columns and the horizontal members can be separated without removing the existing brace hardware and therefore also without affecting the attachment state of the existing brace. It can be easily and appropriately and firmly integrated separately at a place other than the place where the two are connected.

以下、図１〜図１０に基づいて、この発明の典型的な実施の形態について、説明する。 Hereinafter, a typical embodiment of the present invention will be described with reference to FIGS. 1 to 10.

この実施の形態にかかる耐震補強金物１は、既存の建物の耐震性を高めるリフォーム工事において、既設の筋交い金物Ｓを取り外すことなく、したがってまた、既設の筋交いＴの取り付け状態に影響を与えることなく、木製の柱Ｐと木製の横架材Ｂ（土台、梁、桁など）とを両者の取り合い箇所以外の箇所で別途強固に一体化させることを可能とするものである。 The seismic retrofitting hardware 1 according to this embodiment does not remove the existing brace hardware S in the remodeling work for enhancing the seismic resistance of the existing building, and therefore also does not affect the attachment state of the existing brace T. , The wooden pillar P and the wooden horizontal member B (base, beam, girder, etc.) can be separately and firmly integrated at a place other than the place where they are joined.

すなわち、かかる耐震補強金物１は、既設の筋交い金物Ｓを取り外すことなく設置可能で、いわゆる柱頭柱脚金物としての機能を持つ。 That is, the seismic retrofitting hardware 1 can be installed without removing the existing brace hardware S, and has a function as a so-called stigma column base hardware.

また、かかる耐震補強金物１は、後述の耐震補強構造を実現可能とするものである。 Further, the seismic retrofitting hardware 1 makes it possible to realize a seismic retrofitting structure described later.

かかる耐震補強金物１は、柱側取付部２と、横架材側取付部２’と、軸体３（棒状体）とを備える。 The seismic retrofitting hardware 1 includes a pillar-side mounting portion 2, a horizontal member-side mounting portion 2', and a shaft body 3 (rod-shaped body).

柱側取付部２は、柱Ｐにおける前記柱Ｐと横架材Ｂとで囲まれた空間Ｆ（図３参照）に面した側面Ｐａに対して取り付けられる。 The pillar-side mounting portion 2 is mounted on the side surface Pa of the pillar P facing the space F (see FIG. 3) surrounded by the pillar P and the horizontal member B.

前記柱側取付部２は、一面を取付面２ｂとした基板２ａと、前記基板２ａの他面側に形成された軸受け部２ｃとを有する。また、前記柱側取付部２は、前記軸受け部２ｃをもって前記軸体３の一端部３ａに水平軸４をもって回動可能に組み合わされている。 The pillar-side mounting portion 2 has a substrate 2a having one surface as a mounting surface 2b, and a bearing portion 2c formed on the other surface side of the substrate 2a. Further, the pillar-side mounting portion 2 is rotatably combined with the one end portion 3a of the shaft body 3 with the horizontal shaft 4 with the bearing portion 2c.

図示の例では、基板２ａは、実質的に長方形の板状を呈している。図示の例では、基板２ａには、その長さ方向の中程の位置にビスや釘などの軸状止着体の通し穴２ｄが形成されていると共に、この通し穴２ｄと基板２ａの一方の幅側の縁部との間、及び、この通し穴２ｄと基板２ａの他方の幅側の縁部との間にそれぞれ、基板２ａの幅方向において並ぶようにして二つの前記通し穴２ｄが形成されている。 In the illustrated example, the substrate 2a has a substantially rectangular plate shape. In the illustrated example, the substrate 2a is formed with a through hole 2d for a shaft-shaped anchorage such as a screw or a nail at a position in the middle of the substrate 2a, and one of the through hole 2d and the substrate 2a. The two through holes 2d are arranged so as to be aligned in the width direction of the substrate 2a between the edge portion on the width side of the substrate and between the through hole 2d and the other edge portion of the substrate 2a on the width side. It is formed.

軸受け部２ｃは、基板２ａの長さ側の縁部に基部を一体化させて前記他面に直交する向きに突き出す立ち上がり壁部２ｅによって構成されている。立ち上がり壁部２ｅは、基板２ａの二箇所の長さ側の縁部のそれぞれに沿うように二箇所に形成されている。二箇所の立ち上がり壁部２ｅは、基板２ａの長さ方向に沿った仮想の中心線ｘ（図２参照）を中心とした線対称の形状を持つように構成されている。立ち上がり壁部２ｅは、基板２ａの一方の幅側の縁部と長さ側の縁部との接し合う隅部から、基板２ａの他方の幅側の縁部側に近づくに連れて基板２ａからの立ち上がり寸法を漸増させる傾斜縁２ｆと、この傾斜縁２ｆの最上部と基板２ａの他方の幅側の縁部と長さ側の縁部との接し合う隅部との間に亘る弧状縁２ｇとを備えた形態となっている。弧状縁２ｇは仮想の円（図示は省略する）の円弧に沿うように形成されている。二箇所の立ち上がり壁部２ｅにはそれぞれ、円形の軸穴２ｈが形成されている。 The bearing portion 2c is composed of a rising wall portion 2e that integrates a base portion with an edge portion on the length side of the substrate 2a and projects in a direction orthogonal to the other surface. The rising wall portion 2e is formed at two locations along each of the two length-side edges of the substrate 2a. The two rising wall portions 2e are configured to have a line-symmetrical shape centered on a virtual center line x (see FIG. 2) along the length direction of the substrate 2a. The rising wall portion 2e starts from the substrate 2a as it approaches the edge side of the other width side of the substrate 2a from the corner where the edge portion on the one width side and the edge portion on the length side of the substrate 2a are in contact with each other. An arcuate edge 2g extending between the inclined edge 2f that gradually increases the rising dimension of the It is a form equipped with. The arc-shaped edge 2g is formed along the arc of a virtual circle (not shown). Circular shaft holes 2h are formed in each of the two rising wall portions 2e.

また、図示の例では、水平軸４は、前記軸穴２ｈの穴径と外径を実質的に等しくした丸棒状体によって構成されている。水平軸４の長さは、二箇所の立ち上がり壁部２ｅの外面間の距離よりも大きく、水平軸４は、二箇所の立ち上がり壁部２ｅの外面より外側に軸端４ａを位置させるようにして、軸受け部２ｃとしての二箇所の立ち上がり壁部２ｅの軸穴２ｈに通され軸支されるようになっている。 Further, in the illustrated example, the horizontal shaft 4 is formed of a round bar-shaped body having substantially the same outer diameter as the hole diameter of the shaft hole 2h. The length of the horizontal axis 4 is larger than the distance between the outer surfaces of the two rising wall portions 2e, and the horizontal axis 4 positions the shaft end 4a outside the outer surfaces of the two rising wall portions 2e. , The shaft is supported by being passed through the shaft holes 2h of the two rising wall portions 2e as the bearing portions 2c.

また、水平軸４の長さ方向の中程の位置には、水平軸４をその軸線に直交する向きに貫通する貫通穴４ｂが形成されていると共に、この貫通穴４ｂの内部には雌ネジ４ｃが形成されている。 Further, a through hole 4b that penetrates the horizontal axis 4 in a direction orthogonal to the axis is formed at a position in the middle of the horizontal axis 4 in the length direction, and a female screw is formed inside the through hole 4b. 4c is formed.

横架材側取付部２’は、前記横架材Ｂにおける前記空間Ｆ（図３参照）に面した側面Ｂａに対して取り付けられる。 The horizontal member side mounting portion 2'is attached to the side surface Ba of the horizontal member B facing the space F (see FIG. 3).

図示の例では、横架材側取付部２’の構成は、前記柱側取付部２と同一の構成となっていることから、横架材側取付部２’の説明は各図において横架材側取付部２’に柱側取付部２の説明に用いた符号と同一の符号を付してその説明は省略する。 In the illustrated example, since the configuration of the horizontal member side mounting portion 2'is the same as that of the pillar side mounting portion 2, the description of the horizontal member side mounting portion 2'is described in each drawing. The lumber side mounting portion 2'is designated by the same reference numerals as those used in the description of the pillar side mounting portion 2, and the description thereof will be omitted.

軸体３は、柱側取付部２と前記横架材側取付部２’とをつなぐ。 The shaft body 3 connects the pillar side mounting portion 2 and the horizontal member side mounting portion 2'.

軸体３は、前記柱側取付部２に組み合わされる柱側軸部３ｃと、前記横架材側取付部２’に組み合わされる横架材側軸部３ｇとを、両軸部３ｃ、３ｇ間にあって両軸部３ｃ、３ｇにそれぞれネジ付けられるナット体３ｋによって連結させてなる。 The shaft body 3 has a pillar-side shaft portion 3c combined with the pillar-side mounting portion 2 and a horizontal member-side shaft portion 3g combined with the horizontal member-side mounting portion 2'between both shaft portions 3c and 3g. It is connected by a nut body 3k screwed to both shaft portions 3c and 3g, respectively.

柱側軸部３ｃ及び横架材側軸部３ｇはいずれも、丸棒状体によって構成されている。図示の例では、柱側軸部３ｃの一端部３ｄが前記軸体３の一端部３ａとなり、横架材側軸部３ｇの一端部３ｈが前記軸体３の他端部３ｂとなっている。 Both the pillar side shaft portion 3c and the horizontal member side shaft portion 3g are formed of a round bar. In the illustrated example, one end 3d of the pillar side shaft 3c is one end 3a of the shaft 3, and one end 3h of the horizontal member side shaft 3g is the other end 3b of the shaft 3. ..

図示の例では、柱側軸部３ｃの一端部３ｄ側と他端部３ｅ側とにそれぞれ、雄ネジ３ｆが形成されている。一方、横架材側軸部３ｇはその一端部３ｈと他端部３ｉとの間のその全長に亘って雄ネジ３ｊが形成されている。図示は省略するが、柱側軸部３ｃの全長に亘って雄ネジ３ｆを形成してあっても良く、また、横架材側軸部３ｇの一端部３ｈ側と他端部３ｉ側とにそれぞれ雄ネジ３ｊを形成しておくようにしても良い。 In the illustrated example, male screws 3f are formed on one end 3d side and the other end 3e side of the pillar side shaft portion 3c, respectively. On the other hand, the horizontal member side shaft portion 3g has a male screw 3j formed over the entire length between one end portion 3h and the other end portion 3i. Although not shown, a male screw 3f may be formed over the entire length of the pillar-side shaft portion 3c, and may be formed on one end 3h side and the other end 3i side of the horizontal member side shaft portion 3g. Male screws 3j may be formed for each.

ナット体３ｋは、その軸線に直交する向きの断面外郭形状を六角形とすると共に、その一端から他端に亘る雌ネジ穴３ｍを内部に備えた構成となっている。 The nut body 3k has a hexagonal cross-sectional outer shape in a direction orthogonal to its axis, and has a female screw hole 3 m extending from one end to the other end inside.

柱側軸部３ｃの一端部３ｄは、柱側取付部２を構成する一対の立ち上がり壁部２ｅ間において水平軸４の貫通穴４ｂにネジ付けられると共に、柱側軸部３ｃの他端部３ｅは、ナット体３ｋの一端側からこのナット体３ｋの雌ネジ穴３ｍにネジ付けられるようになっている。柱側取付部２を構成する軸受け部２ｃとしての二箇所の立ち上がり壁部２ｅの軸穴２ｈに通されて前記のように軸支された水平軸４に柱側軸部３ｃの一端部３ｄを前記のようにネジ付けると、水平軸４のその軸線方向への移動は柱側軸部３ｃによって阻止され、これにより、軸受け部２ｃと水平軸４と柱側軸部３ｃの三者の組み合わせ状態は安定的に維持される。 One end 3d of the pillar-side shaft portion 3c is screwed into the through hole 4b of the horizontal shaft 4 between the pair of rising wall portions 2e constituting the pillar-side mounting portion 2, and the other end portion 3e of the pillar-side shaft portion 3c. Is screwed into the female screw hole 3 m of the nut body 3k from one end side of the nut body 3k. One end 3d of the pillar side shaft portion 3c is attached to the horizontal shaft 4 which is passed through the shaft holes 2h of the two rising wall portions 2e as the bearing portion 2c constituting the pillar side mounting portion 2 and is pivotally supported as described above. When screwed as described above, the movement of the horizontal shaft 4 in the axial direction is blocked by the pillar side shaft portion 3c, whereby the bearing portion 2c, the horizontal shaft 4 and the pillar side shaft portion 3c are combined. Is maintained stable.

また、横架材側軸部３ｇの一端部３ｈは、横架材側取付部２’を構成する一対の立ち上がり壁部２ｅ間において横架材側取付部２’を構成する水平軸４の貫通穴４ｂにネジ付けられると共に、横架材側軸部３ｇの他端部３ｉは、ナット体３ｋの他端側からこのナット体３ｋの雌ネジ穴３ｍにネジ付けられるようになっている。横架材側取付部２’を構成する軸受け部２ｃとしての二箇所の立ち上がり壁部２ｅの軸穴２ｈに通されて前記のように軸支された水平軸４に横架材側軸部３ｇの一端部３ｈを前記のようにネジ付けると、水平軸４のその軸線方向への移動は横架材側軸部３ｇによって阻止され、これにより、軸受け部２ｃと水平軸４と横架材側軸部３ｇの三者の組み合わせ状態は安定的に維持される。 Further, one end portion 3h of the horizontal member side shaft portion 3g penetrates the horizontal shaft 4 constituting the horizontal member side mounting portion 2'between the pair of rising wall portions 2e constituting the horizontal member side mounting portion 2'. In addition to being screwed into the hole 4b, the other end 3i of the horizontal member side shaft portion 3g is screwed from the other end side of the nut body 3k into the female screw hole 3m of the nut body 3k. The horizontal shaft portion 3g is passed through the shaft holes 2h of the two rising wall portions 2e as the bearing portions 2c constituting the horizontal member side mounting portion 2'and is pivotally supported as described above. When one end portion 3h of the above is screwed as described above, the movement of the horizontal shaft 4 in the axial direction is blocked by the horizontal member side shaft portion 3g, whereby the bearing portion 2c, the horizontal shaft 4 and the horizontal member side are blocked. The combined state of the shaft portion 3g is stably maintained.

以上に説明した耐震補強金物１は、柱側取付部２と横架材側取付部２’とを軸体３でつなぐ構成となっていることから、柱Ｐと横架材Ｂとの取り合い箇所（交点）において、柱Ｐと横架材Ｂとで囲われた空間Ｆ側に備え付けられる既設の筋交い金物Ｓの上方又は下方に前記柱側取付部２を位置させ、かつ、既設の筋交い金物Ｓよりも前記空間Ｆの中央側に前記横架材側取付部２’を位置させ、かつ、前記軸体３を既設の筋交い金物Ｓの斜め上方又は斜め下方に位置させるようにして、柱Ｐと横架材Ｂとを強固に一体化させることができる（図３）。すなわち、かかる耐震補強金物１は、既設の筋交い金物Ｓをまたぐようにして既設の筋交い金物Ｓを取り外すことなく設置可能で、いわゆる柱頭柱脚金物としての機能を持つ。また、かかる耐震補強金物１は、一般的な耐震補強金物とは異なり、柱Ｐと横架材Ｂとの取り合い箇所（交点）より離れた位置で固定されることから、方杖や火打ち金物のような躯体の隅部の直角を保つ機能を兼ね備える。 Since the seismic reinforcement hardware 1 described above has a configuration in which the column side mounting portion 2 and the horizontal member side mounting portion 2'are connected by a shaft body 3, the connection point between the column P and the horizontal member B is provided. At (intersection), the column side mounting portion 2 is positioned above or below the existing brace hardware S provided on the space F side surrounded by the column P and the horizontal member B, and the existing brace hardware S The horizontal member side mounting portion 2'is positioned on the central side of the space F, and the shaft body 3 is positioned diagonally above or diagonally below the existing brace hardware S, so that the pillar P and the pillar P are positioned. The horizontal member B can be firmly integrated (FIG. 3). That is, the seismic retrofitting metal fitting 1 can be installed without removing the existing bracing metal fitting S so as to straddle the existing bracing metal fitting S, and has a function as a so-called stigma column base metal fitting. Further, unlike general seismic retrofitting hardware, the seismic retrofitting hardware 1 is fixed at a position away from the joint point (intersection) between the pillar P and the horizontal member B, so that it is a right angle or a flint metal fitting. It also has the function of maintaining the right angle of the corners of the frame.

図示は省略するが、典型的には、かかる耐震補強金物１は、前記空間Ｆの四隅にそれぞれ取り付けられる(図３）。 Although not shown, typically, the seismic retrofitting hardware 1 is attached to each of the four corners of the space F (FIG. 3).

また、かかる耐震補強金物１は、柱側取付部２と軸体３の一端部３ａとを水平軸４をもって回動可能に組み合わせ、かつ、横架材側取付部２’と軸体３の他端部３ｂとを水平軸４をもって回動可能に組み合わせる構成となっていることから、柱側取付部２の取付面２ｂと軸体３の軸線ｙ（図４参照）とがなす角度を自由に変えることができ、したがって、柱側取付部２及び横架材側取付部２’を状況に応じてもっとも適切と考えられる取り付け位置に取り付けることができる。例えば、柱Ｐや横架材Ｂが二つの材を継ぎ合わせて構成されていてその継ぎ目が柱Ｐと横架材Ｂとの取り合い箇所近傍に位置されている場合にこの継ぎ目に設置される接続金物を避けた柱側取付部２及び横架材側取付部２’の取り付けを容易になすことができる。あるいはまた、横架材Ｂに対するアンカーボルトが柱Ｐと横架材Ｂとの取り合い箇所近傍に位置されている場合にこのアンカーボルトを避けた横架材側取付部２’の取り付けを容易になすことができる。 Further, in the seismic reinforcing metal fitting 1, the column side mounting portion 2 and one end portion 3a of the shaft body 3 are rotatably combined with the horizontal shaft 4, and the horizontal member side mounting portion 2'and the shaft body 3 are also combined. Since the end portion 3b is rotatably combined with the horizontal shaft 4, the angle formed by the mounting surface 2b of the pillar-side mounting portion 2 and the axis y (see FIG. 4) of the shaft body 3 can be freely set. It can be changed, and therefore the column-side mounting portion 2 and the horizontal member-side mounting portion 2'can be mounted at the most appropriate mounting position depending on the situation. For example, when the column P or the horizontal member B is formed by joining two members and the joint is located near the joint between the column P and the horizontal member B, the connection is installed at this joint. The pillar-side mounting portion 2 and the horizontal member-side mounting portion 2'avoidable hardware can be easily mounted. Alternatively, when the anchor bolt for the horizontal member B is located near the joint between the pillar P and the horizontal member B, the horizontal member side mounting portion 2'avoids the anchor bolt can be easily attached. be able to.

また、かかる耐震補強金物１は、軸体３を、柱側軸部３ｃと、横架材側軸部３ｇと、ナット体３ｋとを組み合わせて構成することから、一定の範囲で軸体３の全長を変えることもできる。 Further, since the seismic retrofitting hardware 1 is formed by combining the shaft body 3 with the column side shaft portion 3c, the horizontal member side shaft portion 3g, and the nut body 3k, the shaft body 3 has a certain range. You can also change the total length.

かつ、以上に説明した耐震補強金物１を構成する横架材側取付部２’を、前記横架材Ｂにおける前記空間Ｆに面した側面Ｂａであって前記既設の筋交い金物Ｓよりも前記空間Ｆの中央側に位置される箇所に止着させると共に、
前記軸体３を既設の筋交いＴの側方に位置させるようにすることで、既存の建物の耐震性を高める耐震補強構造が構成される。 The column-side mounting portion 2 constituting the seismic retrofitting hardware 1 described above is a side surface Pa facing the space F surrounded by the column P and the horizontal member B in the column P, and is an existing brace hardware. Settle at a location located above or below S,
