Description

本発明は、天井を耐震補強する耐震補強部材に関する。   The present invention relates to a seismic reinforcement member for seismically reinforcing a ceiling.

従来より、地震時の建物の挙動により、天井下地や天井仕上材に大きな慣性力が作用し、これら天井下地や天井仕上材が破損したり落下したりするおそれがある。そこで、例えば、天井裏空間に耐震補強部材としてブレースを設けることが提案されている。（特許文献１参照）。
このブレースは、例えば、水平面に対して傾斜して直線状に延びる軽量鉄骨の部材であり、このブレースの上端は、天井裏の吊りボルトに係止され、下端は、天井下地である野縁受けあるいは野縁に係止される。 Conventionally, due to the behavior of a building during an earthquake, a large inertial force acts on the ceiling base and the ceiling finishing material, and the ceiling base and the ceiling finishing material may be damaged or dropped. Therefore, for example, it has been proposed to provide a brace as a seismic reinforcement member in the ceiling space. (See Patent Document 1).
The brace is, for example, a lightweight steel frame member that is inclined with respect to a horizontal plane and extends linearly. The upper end of the brace is engaged with a suspension bolt on the back of the ceiling, and the lower end of the brace is a ceiling base. Alternatively, it is locked to the field edge.

しかしながら、以上のようなブレースは、天井裏空間を斜めに延びるため、占有スペースが大きい。したがって、新築建物にブレースを取り付ける場合、天井裏の設備機器をブレースに干渉しないように配置する必要があり、設備レイアウトの自由度が低くなるおそれがあった。
また既存建物にブレースを取り付ける場合、天井内の設備レイアウトを大きく変更するので、施工手間がかかって、コスト高となる場合があった。あるいは、設備レイアウトを変更できず、ブレースを所定位置に取り付けられないので、所定の耐震性能を発揮できない場合があった。 However, since the braces as described above extend obliquely through the ceiling space, the occupied space is large. Therefore, when a brace is attached to a new building, it is necessary to arrange the equipment on the back of the ceiling so as not to interfere with the brace, which may reduce the degree of freedom of the equipment layout.
In addition, when braces are attached to an existing building, the layout of the equipment in the ceiling is greatly changed. Alternatively, the equipment layout cannot be changed, and the brace cannot be attached at a predetermined position, so that the predetermined earthquake resistance performance may not be exhibited.

本発明は、天井内に設備レイアウトの自由度を確保しつつ、低コストで耐震補強できる耐震補強部材を提供することを目的とする。   An object of this invention is to provide the earthquake-resistant reinforcement member which can be seismically reinforced at low cost, ensuring the freedom of an equipment layout in a ceiling.

請求項１に記載の耐震補強部材（例えば、後述の耐震補強部材１）は、野縁受け（例えば、後述の野縁受け１２）と、当該野縁受けに支持されて前記野縁受けに略直交する野縁（例えば、後述の野縁１３）と、当該野縁に支持される板状の天井仕上材（例えば、後述の天井仕上材１４）と、を備える天井（例えば、後述の天井１０）の耐震補強部材であって、梁（例えば、後述の鉄骨梁２０）の下面に取り付けられた板状の基部（例えば、後述の下側プレート３１）と、当該基部に略垂直に設けられて、水平方向に延びるとともに前記天井の一部（例えば、後述の野縁１３、増設野縁１３Ａ、天井仕上材１４）を支持する板状の第１支持部（例えば、後述の第１支持部４０、４０Ａ）と、前記基部に略垂直に設けられて、水平方向でかつ前記第１支持部とは異なる方向に延びるとともに前記天井の一部（例えば、後述の野縁受け１２、増設野縁受け１２Ａ、天井仕上材１４）を支持する板状の第２支持部（例えば、後述の第２支持部５０、５０Ａ）と、を備える。   The seismic reinforcing member according to claim 1 (for example, seismic reinforcing member 1 described later) is supported by a field edge receiver (for example, field edge receiver 12 described later) and the field edge receiver, and is substantially omitted from the field edge receiver. A ceiling (e.g., a ceiling 10 described below) provided with an orthogonal field edge (e.g., a field edge 13 described later) and a plate-like ceiling finishing material (e.g., a ceiling finishing material 14 described below) supported by the field edge. ) And a plate-like base (for example, a lower plate 31 described later) attached to the lower surface of a beam (for example, a steel beam 20 described later), and provided substantially perpendicular to the base. A plate-like first support portion (for example, a first support portion 40 to be described later) that extends in the horizontal direction and supports a part of the ceiling (for example, a field edge 13 to be described later, an additional field edge 13A, and a ceiling finishing material 14). 40A), provided substantially perpendicular to the base, in a horizontal direction and A plate-like second support portion (for example, described later) that extends in a direction different from the one support portion and supports a part of the ceiling (for example, a field edge receiver 12, an additional field edge receiver 12A, and a ceiling finishing material 14 described later). 2nd support part 50, 50A).

請求項２に記載の耐震補強部材は、前記第１支持部は、側面で前記野縁を支持し、前記第２支持部は、前記野縁受けを支持することを特徴とする。   The seismic reinforcement member according to claim 2 is characterized in that the first support portion supports the field edge on a side surface, and the second support portion supports the field edge receiver.

この発明によれば、板状の第１支持部で野縁や天井仕上材などを支持するとともに、板状の第２支持部で天井仕上材を直接支持したり野縁受けを支持したりした。よって、地震時に、野縁の長さ方向の慣性力に対しては、第１支持部が抵抗し、野縁受けの長さ方向の慣性力に対しては、第２支持部が抵抗する。また、鉛直方向の慣性力に対しては、第１支持部および第２支持部で抵抗する。   According to the present invention, the plate-like first support portion supports the field edge and the ceiling finishing material, and the plate-like second support portion directly supports the ceiling finishing material or supports the field edge receiver. . Therefore, at the time of an earthquake, a 1st support part resists the inertia force of the length direction of a field edge, and a 2nd support part resists the inertia force of the length direction of a field edge receiver. Moreover, it resists with respect to the inertia force of a perpendicular direction in a 1st support part and a 2nd support part.

ここで、耐震補強部材は、天井裏の梁下空間のみに設けられるため、占有スペースが小さくなる。よって、新築建物にこの耐震補強部材を取り付ける場合、天井内の設備レイアウトにほとんど干渉しないので、設備レイアウトの自由度を高めることができる。
また、天井裏の梁下空間に大型の設備機器が設けられることはほとんどないので、既存建物にこの耐震補強部材を取り付ける場合、天井内の設備機器同士の間に容易に取り付けることができるから、天井内の設備レイアウトを変更する必要はない。また、耐震補強部材の取付けは梁下空間のみで作業できるので、施工手間もかからないから、コストを低減できる。 Here, since the seismic reinforcement member is provided only in the space under the beam behind the ceiling, the occupied space is reduced. Therefore, when this seismic reinforcement member is attached to a new building, it hardly interferes with the equipment layout in the ceiling, so the degree of freedom in equipment layout can be increased.
In addition, since there is almost no large equipment installed in the space under the beam behind the ceiling, when attaching this seismic reinforcement member to an existing building, it can be easily installed between the equipment in the ceiling, There is no need to change the equipment layout in the ceiling. In addition, the installation of the seismic reinforcement member can be performed only in the space under the beam, so that it does not require construction work, and thus the cost can be reduced.

また、従来のブレースによる耐震補強では、野縁の長さ方向の慣性力に抵抗するブレースと、野縁受けの長さ方向の慣性力に抵抗するブレースと、を設置する必要があった。しかしながら、この発明によれば、１つの耐震補強部材で、野縁の長さ方向の慣性力および野縁受けの長さ方向の慣性力に抵抗できるので、従来のブレースによる耐震補強に比べて、設置箇所が少なくて済み、工期を短縮して、コストを低減できる。   In addition, in the conventional seismic reinforcement using braces, it is necessary to install braces that resist the inertial force in the length direction of the field edge and braces that resist the inertial force in the length direction of the field edge receiver. However, according to the present invention, with one seismic reinforcement member, it is possible to resist the inertial force in the length direction of the field edge and the inertial force in the length direction of the field edge receiver. The number of installation points is small, the construction period is shortened, and the cost can be reduced.

また、耐震補強部材を梁に取り付けるので、天井の直上の床スラブの有無は問わない。つまり、天井の直上が剛性の低い金属屋根であったり、剛性の低いＡＬＣ版であったりしても、耐震補強部材を容易に取り付けることができる。   Moreover, since the seismic reinforcement member is attached to the beam, it does not matter whether there is a floor slab directly above the ceiling. That is, even if the top of the ceiling is a low-rigidity metal roof or a low-rigidity ALC plate, the seismic reinforcement member can be easily attached.

請求項２に記載の耐震補強部材は、前記第１支持部と前記第２支持部とは、互いに当接していることを特徴とする。   The seismic reinforcing member according to claim 2 is characterized in that the first support portion and the second support portion are in contact with each other.

この発明によれば、野縁を支持する第１支持部と野縁受けを支持する第２支持部とを当接させた。よって、野縁の長さ方向の慣性力に対して、第１支持部だけでなく、第２支持部も抵抗したり、野縁受けの長さ方向の慣性力に対して、第２支持部だけでなく、第１支持部も抵抗したりする。したがって、天井の耐震性をさらに向上できる。   According to this invention, the 1st support part which supports a field edge, and the 2nd support part which supports a field edge receptacle were made to contact | abut. Therefore, not only the first support portion but also the second support portion resists the inertia force in the length direction of the field edge, or the second support portion against the inertia force in the length direction of the field edge receiver. In addition, the first support portion is also resisted. Therefore, the earthquake resistance of the ceiling can be further improved.

本発明によれば、耐震補強部材は、天井裏の梁下空間のみに設けられるため、占有スペースが小さくなる。よって、新築建物にこの耐震補強部材を取り付ける場合、天井内の設備レイアウトにほとんど干渉しないので、設備レイアウトの自由度を高めることができる。また、天井裏の梁下空間に大型の設備機器が設けられることはほとんどないので、既存建物にこの耐震補強部材を取り付ける場合、天井内の設備機器同士の間に容易に取り付けることができるから、天井内の設備レイアウトを大きく変更する必要はない。また、耐震補強部材の取付けは梁下空間のみで作業できるので、施工手間もかからないから、コストを低減できる。また、１つの耐震補強部材で、野縁の長さ方向の慣性力および野縁受けの長さ方向の慣性力に抵抗できるので、従来のブレースによる耐震補強に比べて、設置箇所が少なくて済み、工期を短縮して、コストを低減できる。また、耐震補強部材を梁に取り付けるので、天井の直上の床スラブの有無は問わない。つまり、天井の直上が剛性の低い金属屋根であったり、剛性の低いＡＬＣ版であったりしても、耐震補強部材を容易に取り付けることができる。   According to the present invention, since the seismic reinforcement member is provided only in the space under the beam behind the ceiling, the occupied space is reduced. Therefore, when this seismic reinforcement member is attached to a new building, it hardly interferes with the equipment layout in the ceiling, so the degree of freedom in equipment layout can be increased. In addition, since there is almost no large equipment installed in the space under the beam behind the ceiling, when attaching this seismic reinforcement member to an existing building, it can be easily installed between the equipment in the ceiling, There is no need to change the layout of the equipment on the ceiling. In addition, the installation of the seismic reinforcement member can be performed only in the space under the beam, so that it does not require construction work, and thus the cost can be reduced. In addition, since one seismic reinforcement member can resist the inertial force in the length direction of the field edge and the inertial force in the length direction of the field edge receiver, it requires fewer installation locations than conventional earthquake-resistant reinforcement using braces. The construction period can be shortened and the cost can be reduced. Moreover, since the seismic reinforcement member is attached to the beam, it does not matter whether there is a floor slab directly above the ceiling. That is, even if the top of the ceiling is a low-rigidity metal roof or a low-rigidity ALC plate, the seismic reinforcement member can be easily attached.

以上の耐震補強部材１は、以下の手順で天井１０に取り付けられる。
まず、耐震補強部材１の一部を予め製作しておく。具体的には、取付け部３０の下側プレート３１に、第１支持部４０の第１支持プレート４１および第２支持部５０の第２支持プレート５１を溶接で取り付けるとともに、これら第１支持プレート４１と第２支持プレート５１とを溶接で接合し、補強部材本体２とする。 The above seismic reinforcement member 1 is attached to the ceiling 10 in the following procedure.
First, a part of the earthquake-resistant reinforcing member 1 is manufactured in advance. Specifically, the first support plate 41 of the first support part 40 and the second support plate 51 of the second support part 50 are attached to the lower plate 31 of the attachment part 30 by welding, and the first support plate 41 And the second support plate 51 are joined by welding to form the reinforcing member body 2.

ステップ１では、補強部材本体２を鉄骨梁２０の下フランジ２１の下面に位置決めする。このとき、第１支持プレート４１が野縁１３の直上に位置し、第２支持プレート５１が野縁受け１２の直上に位置するようにする。
ステップ２では、一対の上側プレート３２Ａ、３２Ｂ、介装プレート３３、および連結部材３４を用いて、補強部材本体２を鉄骨梁２０に固定する。 In step 1, the reinforcing member body 2 is positioned on the lower surface of the lower flange 21 of the steel beam 20. At this time, the first support plate 41 is positioned directly above the field edge 13, and the second support plate 51 is positioned directly above the field edge receiver 12.

By using the first adjustment plate 42 in this way, the construction error of the field edge 13 is absorbed.

また、第２調整プレート５２の上側を第２支持プレート５１に重ねるとともに、下側を野縁受け１２に重ねて配置し、この状態で、ボルト５３、ビス５４を用いて、第２調整プレート５２を第２支持プレート５１に固定するとともに、野縁受け１２を第２調整プレート５２に固定する。このように第２調整プレート５２を用いることで、野縁受け１２および天井仕上材１４の施工誤差を吸収する。   In addition, the upper side of the second adjustment plate 52 is overlapped with the second support plate 51 and the lower side is overlapped with the field receiver 12, and in this state, the second adjustment plate 52 is used with the bolts 53 and screws 54. Is fixed to the second support plate 51, and the field receiver 12 is fixed to the second adjustment plate 52. By using the second adjustment plate 52 in this way, construction errors of the field edge receiver 12 and the ceiling finishing material 14 are absorbed.

ステップ５では、天井仕上材１４を施工する。このとき、天井仕上材１４を第２調整プレート５２の折返し部５２１にビス５５で固定する。   In step 5, the ceiling finishing material 14 is constructed. At this time, the ceiling finishing material 14 is fixed to the folded portion 521 of the second adjustment plate 52 with screws 55.

本実施形態によれば、以下のような効果がある。
（１）板状の第１支持部４０の側面で野縁１３を支持するとともに、板状の第２支持部５０の側面で野縁受け１２および天井仕上材１４を支持した。よって、地震時に、野縁１３の長さ方向の慣性力に対しては、第１支持部４０が抵抗し、野縁受け１２の長さ方向の慣性力に対しては、第２支持部５０が抵抗する。また、鉛直方向の慣性力に対しては、第１支持部４０および第２支持部５０で抵抗する。 According to this embodiment, there are the following effects.
(1) While supporting the field edge 13 by the side surface of the plate-shaped 1st support part 40, the field edge receiver 12 and the ceiling finishing material 14 were supported by the side surface of the plate-shaped 2nd support part 50. Therefore, during the earthquake, the first support portion 40 resists the inertial force in the length direction of the field edge 13, and the second support portion 50 against the inertial force in the length direction of the field edge receiver 12. Resists. Further, the first support portion 40 and the second support portion 50 resist against the inertia force in the vertical direction.

ここで、耐震補強部材１は、天井裏の梁下空間のみに設けられるため、占有スペースが小さくなる。よって、新築建物にこの耐震補強部材１を取り付ける場合、天井内の設備レイアウトにほとんど干渉しないので、設備レイアウトの自由度を高めることができる。   Here, since the seismic reinforcement member 1 is provided only in the space under the beam behind the ceiling, the occupied space is reduced. Therefore, when this seismic reinforcement member 1 is attached to a new building, it hardly interferes with the equipment layout in the ceiling, so that the degree of freedom of the equipment layout can be increased.

また、既存建物にこの耐震補強部材１を取り付ける場合、天井内の設備機器同士の間に容易に取り付けることができるから、天井内の設備レイアウトを大きく変更する必要はない。また、耐震補強部材１の取付けは梁下空間のみで作業できるので、施工手間もかからないから、コストを低減できる。   Moreover, when attaching this seismic reinforcement member 1 to an existing building, since it can be easily attached between the equipment in the ceiling, it is not necessary to greatly change the equipment layout in the ceiling. Moreover, since the installation of the seismic reinforcement member 1 can be performed only in the space under the beam, it does not require construction work, so the cost can be reduced.

また、１つの耐震補強部材１で、野縁１３の長さ方向の慣性力および野縁受け１２の長さ方向の慣性力に抵抗できるので、従来のブレースによる耐震補強に比べて、設置箇所が少なくて済み、工期を短縮して、コストを低減できる。   In addition, since one seismic reinforcement member 1 can resist the inertial force in the length direction of the field edge 13 and the inertial force in the length direction of the field edge receiver 12, the installation location is smaller than that of the conventional seismic reinforcement by braces. The cost can be reduced by shortening the construction period.

また、耐震補強部材１を鉄骨梁２０に取り付けるので、天井１０の直上の床スラブの有無は問わない。つまり、天井１０の直上が剛性の低い金属屋根であったり、剛性の低いＡＬＣ版であったりしても、耐震補強部材１を容易に取り付けることができる。   Moreover, since the seismic reinforcement member 1 is attached to the steel beam 20, the presence or absence of a floor slab directly above the ceiling 10 does not matter. That is, even if the top of the ceiling 10 is a metal roof with low rigidity or an ALC plate with low rigidity, the seismic reinforcement member 1 can be easily attached.

（２）野縁１３を支持する第１支持部４０の第１支持プレート４１と、野縁受け１２を支持する第２支持部５０の第２支持プレート５１と、を互いに当接させて溶接で接合した。よって、野縁１３の長さ方向の慣性力に対して、第１支持部４０だけでなく、第２支持部５０も抵抗する。また、野縁受け１２の長さ方向の慣性力に対して、第２支持部５０だけでなく、第１支持部４０も抵抗する。したがって、天井１０の耐震性をさらに向上できる。   (2) The first support plate 41 of the first support part 40 that supports the field edge 13 and the second support plate 51 of the second support part 50 that supports the field edge receiver 12 are brought into contact with each other by welding. Joined. Therefore, not only the first support portion 40 but also the second support portion 50 resists the inertial force in the length direction of the field edge 13. Moreover, not only the 2nd support part 50 but the 1st support part 40 resists the inertial force of the longitudinal direction of the field receiver 12. Therefore, the earthquake resistance of the ceiling 10 can be further improved.

（３）予め補強部材本体２を製作しておき、この補強部材本体２を、一対の上側プレート３２Ａ、３２Ｂ、介装プレート３３、および連結部材３４を用いて、鉄骨梁２０に取り付け、その後、第１調整プレート４２および第２調整プレート５２を取り付ける。よって、施工現場で溶接を用いる必要がないので、鉄骨梁２０の断面性能が低下するのを防止できる。また、特に既存建物に耐震補強部材１を取り付ける場合、溶接火花による火災や天井下地材、床、室内の備品などの汚損を有効に防止できる。   (3) The reinforcing member body 2 is manufactured in advance, and the reinforcing member body 2 is attached to the steel beam 20 using the pair of upper plates 32A and 32B, the interposition plate 33, and the connecting member 34, and then The first adjustment plate 42 and the second adjustment plate 52 are attached. Therefore, since it is not necessary to use welding at the construction site, it is possible to prevent the cross-sectional performance of the steel beam 20 from being deteriorated. In particular, when the seismic reinforcement member 1 is attached to an existing building, it is possible to effectively prevent fires caused by welding sparks, contamination of ceiling base materials, floors, indoor equipment, and the like.

(4) A partition wall 60 reaching the steel beam 20 can be provided, and separate ceilings 10A can be simultaneously supported with the partition wall 60 interposed therebetween.

For example, in each of the above-described embodiments, the attachment portion 30 is attached to the steel beam 20 by tightening the bolt 341 and sandwiching the lower flange 21 of the steel beam 20 between the lower plate 31 and the upper plates 32A and 32B. Not limited to this.

例えば、図７に示すように、予め、一方の上側プレート３２Ａを下側プレート３１と一体化しておき、図７中二点鎖線で示すように、上側プレート３２Ａを下フランジ２１に引っ掛けて、その後、上側プレート３２Ｂおよび介装プレート３３を連結部材３４で下側プレート３１に連結することで、取付け部３０Ｂを鉄骨梁２０に取り付けてもよい。   For example, as shown in FIG. 7, one upper plate 32A is integrated with the lower plate 31 in advance, and the upper plate 32A is hooked on the lower flange 21 as shown by a two-dot chain line in FIG. The attachment portion 30B may be attached to the steel beam 20 by connecting the upper plate 32B and the interposed plate 33 to the lower plate 31 by the connecting member 34.

May be.

また、上述の各実施形態では、耐震補強部材１を鉄骨梁２０に取付け、変形例では、耐震補強部材１を鉄筋コンクリート梁に取り付けたが、これに限らない。すなわち、Ｈ形鋼、溝形鋼、山形鋼を組み合わせたトラス梁に取り付けてもよいし、逆梁に取り付けてもよい。   Moreover, in each above-mentioned embodiment, although the earthquake-proof reinforcement member 1 was attached to the steel beam 20, and in the modification, the earthquake-proof reinforcement member 1 was attached to the reinforced concrete beam, it is not restricted to this. That is, you may attach to the truss beam which combined H-section steel, channel steel, and angle steel, and you may attach to a reverse beam.

また、上述の各実施形態では、第１支持部４０、４０Ａと第２支持部５０、５０Ａとを互いに当接させたが、これに限らず、第１支持部と第２支持部とを離して設けてもよい。   In each of the above-described embodiments, the first support part 40, 40A and the second support part 50, 50A are brought into contact with each other. However, the present invention is not limited to this, and the first support part and the second support part are separated from each other. May be provided.

また、耐震補強部材１を構成する部材の厚みや大きさ、および、耐震補強部材１に用いられるビスやボルトの径や本数は、必要に応じて適宜決定されてよい。   In addition, the thickness and size of the members constituting the seismic reinforcement member 1 and the diameters and number of screws and bolts used in the seismic reinforcement member 1 may be appropriately determined as necessary.

また、耐震補強部材１を天井１０に取り付ける手順は、上述のステップ１〜５に限らない。例えば、ステップ２とステップ３とを入れ替えてもよい。   Moreover, the procedure for attaching the seismic reinforcement member 1 to the ceiling 10 is not limited to the above steps 1 to 5. For example, step 2 and step 3 may be interchanged.

また、上述の第１実施形態では、第１支持プレート４１と第２支持プレート５１とを溶接で接合したが、これに限らず、溶接で接合せず、当接させただけでもよい。   In the first embodiment described above, the first support plate 41 and the second support plate 51 are joined by welding. However, the present invention is not limited to this.

また、本発明の耐震補強部材１〜１Ｅをブレースと併用してもよい。例えば、天井裏の梁下の空間に耐震補強部材１〜１Ｅを設け、スラブ下の空間に適宜ブレースを設ける構造としてもよい。   Moreover, you may use the seismic reinforcement member 1-1E of this invention together with a brace. For example, it is good also as a structure which provides the earthquake-resistant reinforcement members 1-1E in the space under the beam of a ceiling back, and provides a brace suitably in the space under a slab.

また、各実施形態において、鉄骨梁２０の下フランジ２１と取付け部３０の下側プレート３１との間に、第１支持プレート４１、４１Ａと第１調整プレート４２との間、第２支持プレート５１、５１Ａと第２調整プレート５２との間に、ゴムなどのクッション材を介装してもよい。耐震補強は全体の剛性のバランスが重要であり、剛性の高い箇所に応力が集中してしまうので、耐震補強部材１の剛性を下げる必要が生じる場合がある。このような場合、クッション材を用いることで、容易に剛性を下げることができる。   In each embodiment, between the lower flange 21 of the steel beam 20 and the lower plate 31 of the attachment portion 30, between the first support plates 41, 41 </ b> A and the first adjustment plate 42, the second support plate 51. A cushioning material such as rubber may be interposed between the first adjustment plate 52 and the first adjustment plate 52. In the seismic reinforcement, the balance of the overall rigidity is important, and stress concentrates on a portion having high rigidity. Therefore, it may be necessary to reduce the rigidity of the seismic reinforcement member 1. In such a case, the rigidity can be easily lowered by using a cushion material.

また、耐震補強部材１〜１Ｅの野縁受け１２や野縁１３との位置合わせが困難な場合には、増設野縁受け１２Ａや増設野縁１３Ａを設けてもよい。すなわち、図１２に示すように、既存の野縁受け１２に略平行に増設野縁受け１２Ａを設けるとともに、既存の野縁１３に略平行に増設野縁１３Ａを設ける。   Further, when it is difficult to align the seismic reinforcement members 1 to 1E with the field edge receiver 12 or the field edge 13, an additional field edge receiver 12A or an expansion field edge 13A may be provided. That is, as shown in FIG. 12, an additional field edge 12 </ b> A is provided substantially parallel to the existing field edge 12, and an additional field edge 13 </ b> A is provided substantially parallel to the existing field edge 13.

このようにすれば、耐震補強部材１の位置に応じて増設野縁受け１２Ａや増設野縁１３Ａを配置すればよいので、耐震補強部材１を既存の野縁受け１２や野縁１３の位置に合わせて配置する必要がなく、耐震補強部材１の施工性が向上する。
なお、増設野縁１３Ａを取り付ける場合、予め増設野縁１３Ａを第１調整プレート４２に取り付けておき、第１調整プレート４２とともに増設野縁１３Ａを取り付けてもよいし、先に増設野縁１３Ａを取り付けて、その後、第１調整プレート４２を取り付けてもよい。

There is no need to arrange them together, and the workability of the seismic reinforcement member 1 is improved.
In addition, when attaching the extension field edge 13A, the extension field edge 13A may be attached to the first adjustment plate 42 in advance, and the extension field edge 13A may be attached together with the first adjustment plate 42. After attaching, the 1st adjustment plate 42 may be attached after that.
In addition, when the extension field receiver 12A is attached, the extension field receiver 12A may be attached to the second adjustment plate 52 in advance, and the extension field receiver 12A may be attached together with the second adjustment plate 52. The edge receiver 12A may be attached, and then the second adjustment plate 52 may be attached.
