Description

本発明は、構造物の耐震性を増加するために既設梁柱架構の内面に増設する枠付補強架構およびこれを利用した既設梁柱架構の補強構造に関する。 The present invention relates to a framed reinforcing frame that is added to the inner surface of an existing beam column frame in order to increase the earthquake resistance of the structure, and a reinforcing structure for an existing beam column frame using the frame.

耐震性が不十分であると判断された既設建物に対する一般的な補強構造としては、例えば柱と梁から形成される既設梁柱架構の架構内面に、鉄骨により構成された長方形の枠の内部に鉄骨ブレース（補強部材）が設けられている、枠付補強架構（架構補強用面材）を増設することにより、既設建物の剛性と耐力とを増加させる補強構造がある（例えば特許文献１）。
特開平１１−７１９０６号公報（［００１６］−［００１９］、図１） As a general reinforcement structure for existing buildings that are judged to be insufficient in earthquake resistance, for example, on the inner surface of an existing beam column structure formed of columns and beams, inside a rectangular frame made of steel frames There is a reinforcing structure that increases the rigidity and proof strength of an existing building by adding a framed reinforcing frame (frame reinforcing surface member) provided with a steel brace (reinforcing member) (for example, Patent Document 1).
JP 11-71906 A ([0016]-[0019], FIG. 1)

これらの枠付補強架構の形状は、既設建物の内面形状に合せて適宜変更されており、例えば、図５に示すように、左右の柱部材１２１と上下の梁部材１２２とから形成され、柱部材１２１と梁部材１２２との接合部に垂直ハンチ１２３を有する既設梁柱架構１２０の内面においては、既設梁柱架構１２０の形状に合せて枠付補強架構１１０にもハンチ部１１３を設けた六角形形状に形成する場合がある。   The shapes of these framed reinforcing frames are appropriately changed in accordance with the inner surface shape of the existing building. For example, as shown in FIG. 5, the frame is formed of left and right column members 121 and upper and lower beam members 122. On the inner surface of the existing beam column frame 120 having the vertical hunch 123 at the joint between the member 121 and the beam member 122, the haunch portion 113 is also provided on the framed reinforcement frame 110 in accordance with the shape of the existing beam column frame 120. It may be formed in a square shape.

しかしながら、通常、建物の天井裏には電気配線等１３１やダクト１３２が配設されており、美感上、天井１３０を設けて目隠しを行う。そのため、枠付補強架構１１０を既設梁柱架構１２０に設置すると、枠付補強架構１１０の上側水平枠材１１２が梁部材１２２に沿って配設されるため、ダクト１３２や電気配線等１３１の配設に必要な断面積を確保するためには、天井１３０を低くするなどの処置が必要となり、既設建物利用者に補強前より圧迫感を与えるという問題点を有していた。一方、天井１３０が低くならないように、梁部材１２２に孔を開けて各種必要設備を配置する場合もあるが、供用中の建物の場合、削孔時の騒音・振動や粉塵による環境問題や、梁部材１２２に孔をあけることにより梁部材１２２の耐力が低下するため、梁部材１２２に設けた各孔の補強工や枠付補強架構１１０の耐力を増加することによる工事費の増加などの問題点を有していた。   However, in general, electrical wiring 131 and ducts 132 are disposed behind the ceiling of the building, and the ceiling 130 is provided for blinding for aesthetic reasons. Therefore, when the framed reinforcing frame 110 is installed on the existing beam column frame 120, the upper horizontal frame material 112 of the framed reinforcing frame 110 is disposed along the beam member 122. In order to secure the cross-sectional area necessary for installation, measures such as lowering the ceiling 130 are necessary, and there is a problem that the existing building user is given a feeling of pressure before reinforcement. On the other hand, in order to prevent the ceiling 130 from being lowered, various necessary facilities may be arranged by drilling holes in the beam member 122. However, in the case of a building in service, environmental problems due to noise, vibration and dust during drilling, Since the proof strength of the beam member 122 is reduced by making a hole in the beam member 122, problems such as an increase in construction cost due to the reinforcement of each hole provided in the beam member 122 and the proof strength of the framed reinforcing frame 110 are increased. Had a point.

さらに、図５に示す枠付補強架構１１０のように、既設梁柱架構１２０の形状に合せてハンチ部１１３を形成するような場合、鉄骨材の加工や溶接作業等に手間がかかり、枠付補強架構１１０の製造に費用と時間がかさむという問題点を有していた。   Further, in the case where the haunch portion 113 is formed in accordance with the shape of the existing beam column frame 120 as in the frame-reinforced frame 110 shown in FIG. The manufacturing of the reinforcing frame 110 has a problem of increasing costs and time.

本発明は、前記の問題点を解決することを目的とするものであり、製造が容易で、施工時の環境にも配慮し、且つ、天井を低くすることなく所望の空間を確保することが可能な、構造物の耐震補強のための枠付補強架構およびこれを利用した既設梁柱架構の補強構造を提案することを課題とする。 The present invention aims to solve the above-mentioned problems, is easy to manufacture, considers the environment during construction, and secures a desired space without lowering the ceiling. It is an object of the present invention to propose a reinforced structure with a frame for seismic reinforcement of a structure and a reinforcing structure of an existing beam column structure using the frame.

また、請求項２に記載の発明は、両側に立設した柱部材と当該両側の柱部材に横設されている上下の梁部材とから形成されている既設梁柱架構の内面に設置される枠付補強架構であって、長方形形状の枠部材と、前記枠部材を補強するための補強部材と、前記枠部材の少なくとも上面又は下面のいずれか一方の両端部にそれぞれ前記柱部材と前記梁部材との隅角部に当接するように形成された四角形状部材と、を備え、前記両四角形状部材の間に凹部が形成されていることを特徴としている。
さらに、請求項３に記載の発明は、両側に立設した柱部材と当該両側の柱部材に横設されている上下の梁部材と、前記両側の柱部材と前記上下の梁部材の内面に設置された請求項１または請求項２に記載の枠付補強架構と、から形成された既設梁柱架構の補強構造であって、前記凹部又は前記スペースにダクトや電線等の配管設備が配置されることを特徴としている。 In order to solve the above-mentioned problems, the invention according to claim 1 is an existing beam column structure formed of column members standing on both sides and upper and lower beam members horizontally provided on the column members on both sides.

As shown in FIG. 2, the triangular member 15 is a member formed by combining steel plates having a predetermined thickness. In the present embodiment, one rectangular inclined steel plate 15a and one triangular triangular member are used. It is composed of a steel plate 15b and a total of four rectangular reinforcing plates 15c and 15d. The triangular steel plate 15 b is welded so as to stand upright at the end of the horizontal member 12 on the upper side of the frame member 11, and the upper end of the triangular steel plate 15 b has the same angle as the angle of the vertical hunch 24 of the existing beam column frame 20.

A slanted steel plate 15a having a width slightly larger than the width of the vertical hunch 24 is in contact with the vertical hunch 24 at the upper end of the triangular steel plate 15b, and is perpendicular to the triangular steel plate 15b so that the cross-sectional shape is T-shaped. And welded together. Further, reinforcing plates 15c and 15d are welded and joined at four desired positions between the inclined steel plate 15a and the horizontal member 12, and the triangular member 15 is firmly fixed to the frame member 11. Has been made. Further, on the upper surface of the inclined steel plate 15a, a fall-preventing plate 15e, which is a rectangular steel plate, is installed at two positions around the center in the longitudinal direction of the left and right sides so that the vertical haunch 24 can be sandwiched.

ここで、三角形状部材１５の枠付補強架構１０への接合を溶接によるものとしたが、三角形状部材１５の下端に鋼板を設けた構成としてボルトによる螺合する等、三角形状部材１５の接合方法は限定されるものではない。また、本実施の形態では、斜鋼板１５ａと三角鋼板１５ｂとを、断面形状がＴ字となるように構成したが、これに限定するものではなく、断面形状が門型や箱型に形成するなど、その形状は限定されるものではない。さらに、三角形状部材１５を鋼板により構成するものではなく、例えば、Ｈ型鋼を加工して構成するものとしても良い。   Here, although the joining of the triangular member 15 to the framed reinforcing frame 10 is made by welding, the joining of the triangular member 15 such as screwing with a bolt as a configuration in which a steel plate is provided at the lower end of the triangular member 15. The method is not limited. In the present embodiment, the inclined steel plate 15a and the triangular steel plate 15b are configured so that the cross-sectional shape is T-shaped, but the present invention is not limited to this, and the cross-sectional shape is formed in a gate shape or a box shape.

枠付補強架構１０の既設梁柱架構２０への取り付けは、枠付補強架構１０の下側の水平部材１２、垂直部材１３及び三角形状部材１５と既設梁柱架構２０との隙間にモルタル等の充填材を充填することにより行う。ここで、取り付けに使用する充填材は、枠付補強架構１０と既設梁柱架構２０の一体化が可能であれば限定されるものではない。また、枠付補強架構１０の既設梁柱架構２０への取り付け方法は限定されるものではなく、場合により、摩擦工法やアンカー工法等から適宜選定して行うことができる。   The reinforced frame 10 with the frame is attached to the existing beam column frame 20 with a mortar or the like in the gap between the horizontal member 12, the vertical member 13 and the triangular member 15 on the lower side of the frame reinforced frame 10 and the existing beam column frame 20. This is done by filling with a filler. Here, the filler used for attachment is not limited as long as the framed reinforcing frame 10 and the existing beam pillar frame 20 can be integrated. Moreover, the attachment method to the existing beam pillar frame 20 of the reinforcement frame 10 with a frame is not limited, According to the case, it can select suitably from a friction construction method, an anchor construction method, etc.

［作用及び効果］
本発明による既設梁柱架構の補強構造は、枠付補強架構１０の上方に設けられた左右の三角形状部材１５が所定の間隔を有して配置されていることにより、既設梁柱架構２０へ取り付けた場合に、上梁部材２２と上側の水平部材１２との間に、凹部Ｓに対応した空間が形成される。そして、この凹部Ｓを、天井裏に配設されるダクト３２や電線等の配管設備３１の配設スペースとして利用すれば、従来の枠付補強架構を利用した補強構造（図５参照）に比べ、天井３０を高く配置することが可能となる。
つまり、本発明の既設梁柱架構の補強構造によれば、従来は上梁部材２２の直下に枠部材１１の上側の水平部材１２が配置されていたため、ダクト３２や電線等の配管設備３１等は水平部材１２の下に配設する必要があったが、枠付補強架構１０の上方に予めダクト３２や電線等の配管設備３１を配設するための空間（凹部Ｓ）が確保されているため、上梁部材２２の直下にダクト３２や電線等の配管設備３１等の配設が可能となり、少なくとも水平部材１２分の高さは、天井を高くすることが可能となる。そのため、天井が高くなることで、建物利用者に開放感を与えることが可能となるとともに、建物の利便性が増す。 [Action and effect]
In the reinforcing structure of the existing beam column structure according to the present invention, the left and right triangular members 15 provided above the framed reinforcement frame 10 are arranged with a predetermined interval, so that the existing beam column structure 20 is provided. When attached, a space corresponding to the recess S is formed between the upper beam member 22 and the upper horizontal member 12. And if this recessed part S is utilized as arrangement | positioning space of piping equipment 31, such as the duct 32 and electric wire etc. which are arrange | positioned behind a ceiling, compared with the reinforcement structure (refer FIG. 5) using the conventional framed reinforcement frame. It becomes possible to arrange the ceiling 30 high.
That is, according to the reinforcing structure of the existing beam column structure of the present invention, since the horizontal member 12 on the upper side of the frame member 11 is conventionally disposed directly below the upper beam member 22, the piping equipment 31 such as the duct 32 and the electric wire, etc. However, the space (recess S) for arranging the piping equipment 31 such as the duct 32 and the electric wire is secured in advance above the framed reinforcing frame 10. Therefore, it is possible to dispose the duct 32 and the piping equipment 31 such as an electric wire directly below the upper beam member 22, and at least the height of the horizontal member 12 can increase the ceiling. Therefore, an increase in the ceiling makes it possible to give the building user a feeling of opening and increase the convenience of the building.

また、本発明による枠付補強架構１０の枠部材１１は、直材である鉄骨を組み合わせて長方形を形成する簡易な構造なため、容易に製造ができる。また、枠部材１１の上面両端に配置する三角形状部材１５も、鋼板を組み合わせてなる簡易な構成である。したがって、従来の、既設梁柱架構２０の垂直ハンチ２４に合せて、鉄骨を曲げるなどして構成する枠付補強架構（図５参照）に比べて、製造が容易であるため、材料製作費用を削減することが可能となり、経済的にも有利である。   Further, the frame member 11 of the framed reinforcing frame 10 according to the present invention can be easily manufactured because it has a simple structure in which a rectangular steel is formed by combining steel frames that are direct materials. Moreover, the triangular member 15 arrange | positioned at the upper surface both ends of the frame member 11 is also a simple structure which combines a steel plate. Therefore, it is easier to manufacture than the conventional framed reinforcement frame (see FIG. 5) constructed by bending a steel frame in accordance with the vertical haunch 24 of the existing beam column frame 20, so the material production cost is reduced. This can be reduced and is economically advantageous.

また、三角形状部材１５に倒れ止めプレート１５ｅが、前後に２箇所配置されていることにより、施工時において、前後の倒れ止めプレート１５ｅ，１５ｅにより、垂直ハンチ２４を挟持すれば、枠付補強架構１０が倒れることを防止し、安全性が確保される。   Further, since the fall-prevention plates 15e are arranged at two positions on the front and rear sides of the triangular member 15, if the vertical haunch 24 is sandwiched between the front and rear fall-prevention plates 15e and 15e at the time of construction, a frame-reinforced reinforcement frame is provided. 10 is prevented from falling, and safety is ensured.

また、地震時において既設梁柱架構２０に加わる応力は、主に柱部材２１と垂直ハンチ２４と下の左右角部分にのみ加わり、上下梁部材２２，２３の中央部には加わらないため、枠付補強架構１０の取り付けについて、下側の水平部材１２、垂直部材１３及び三角形状部材１５と既設梁柱架構２０との隙間について固定を行えば、補強構造としての効果を十分に発現することが可能となる。   In addition, the stress applied to the existing beam column frame 20 at the time of the earthquake is mainly applied only to the column member 21 and the vertical hunch 24 and the lower left and right corners, and not to the central portions of the upper and lower beam members 22 and 23.
