Description

本発明は、建築物における柱と梁で囲まれた構面内に構築される耐震補強構造に関する。   The present invention relates to a seismic reinforcement structure constructed in a construction surface surrounded by columns and beams in a building.
従来、既存建築物の耐震補強において、柱と梁に囲まれた構面内に耐震壁を構築し、既存建築物の保有水平耐力の増大を図ることが行われている。その構造として、耐震強度を考慮して構面内にK型やマンサード型など様々な形状の鉄骨ブレースを設けたものがある(例えば、特許文献1参照)。
特許文献1は、二本の鉄骨ブレースを構面内で略ハの字又は上下逆の略ハの字型となるように斜めに配置させて、上部或いは下部の梁の略中間で互いに連結させ、この連結部で二本の鉄骨ブレースを鋼板などからなるはさみ部材によって挟持させ、このはさみ部材を梁に沿って水平方向に摺動可能に設けた耐震補強構造である。このような摺動構造としたことで、構面内において、地震時に鉄骨ブレースに伝達される力を減衰させるダンパー機能をもたせることができ、水平剛性を向上させたものである。
特開2003−155836号公報
Conventionally, in the seismic reinforcement of an existing building, a seismic wall is constructed in a structural surface surrounded by columns and beams to increase the horizontal strength of the existing building. As a structure thereof, there is a structure in which steel braces having various shapes such as a K type and a mansard type are provided in the surface in consideration of seismic strength (for example, see Patent Document 1).
In Patent Document 1, two steel braces are arranged obliquely so as to have a substantially square shape or an upside-down substantially square shape in the composition plane, and are connected to each other in the middle of the upper or lower beam. In this seismic reinforcing structure, two steel braces are sandwiched by a scissor member made of a steel plate or the like at the connecting portion, and the scissor member is slidable in the horizontal direction along the beam. By adopting such a sliding structure, it is possible to provide a damper function for attenuating the force transmitted to the steel brace during an earthquake in the construction surface, and to improve the horizontal rigidity.
JP 2003-155836 A
しかしながら、特許文献1や従来の鉄骨ブレースでは、効果的な耐震性能を発揮させるために、鉄骨ブレースが構面内全体にわたって斜めに配置されていている。このとき、構面内の鉄骨ブレース同士に囲まれてなる開口部は、建築物としての用途上、有効活用しにくい略三角形状となる場合が多く、例えば窓のような用途に制限されてしまうという欠点があった。すなわち、構面内に出入口や通路といった用途に必要な四角形のスペースを確保してデザインすることが困難であるという問題があった。   However, in patent document 1 and the conventional steel brace, in order to exhibit effective seismic performance, the steel brace is diagonally arrange | positioned over the whole construction surface. At this time, the opening part surrounded by the steel braces in the construction surface often has a substantially triangular shape that is difficult to effectively use for the purpose of the building, and is limited to the use like a window, for example. There was a drawback. That is, there has been a problem that it is difficult to design with a rectangular space necessary for an application such as an entrance and a passage in the construction surface.
本発明は、上述する問題点に鑑みてなされたもので、構面内において出入口や通路などの用途に合わせてデザインできるようにした建築物の耐震補強構造を提供することを目的としている。   The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a seismic reinforcement structure for a building that can be designed in accordance with uses such as an entrance and a passage in a construction surface.

本発明では、外フレームの内側で斜め連結材を斜め方向に配置することで、従来の鉄骨ブレースと同様の耐震構造を実現することができる。そして、例えば内フレームの枠材を外フレームに平行となるように配列させることで、内フレームの内側及びその外側に形成される開口部には、用途として有効活用できる開口率の大きな四角形をなす領域を確保することができる。
In order to achieve the above object, the building earthquake-proof reinforcement structure according to the present invention is an earthquake-proof reinforcement structure constructed in a construction surface surrounded by columns and beams constituting the building, and is incorporated in the construction surface. An outer frame that is framed in a rectangular shape, an inner frame that is disposed at a predetermined interval from the whole or a part of the inner periphery of the outer frame, and that is framed so as to form a rectangular area inside, and the inner frame and the outer frame. It is characterized by comprising an oblique connecting member arranged in an oblique direction by connecting the corners with the frame.
In the present invention, the same earthquake resistant structure as that of the conventional steel brace can be realized by arranging the diagonal connecting members in the diagonal direction inside the outer frame. Then, for example, by arranging the frame material of the inner frame so as to be parallel to the outer frame, the openings formed on the inner side and the outer side of the inner frame form a quadrangle having a large opening ratio that can be effectively used as a use. An area can be secured.
また、本発明に係る建築物の耐震補強構造では、外フレーム及び内フレームの夫々の縦材が略平行に配設されていることが好ましい。
本発明では、外フレームと内フレームとの各縦材が所定の間隔をもって略平行に配設されることから、内フレームの内側及びその隣に縦方向に平行した開口部が形成され、有効活用できる領域を確保することができる。
Moreover, in the earthquake-proof reinforcement structure of the building which concerns on this invention, it is preferable that each vertical member of an outer frame and an inner frame is arrange | positioned substantially parallel.
In the present invention, since the vertical members of the outer frame and the inner frame are arranged substantially in parallel with a predetermined interval, an opening parallel to the vertical direction is formed inside and next to the inner frame for effective use. A possible area can be secured.
また、本発明に係る建築物の耐震補強構造では、内フレームの内側に板状のパネル又は網目状をなす網目部材が組み込まれていることが好ましい。
本発明では、内フレームの内側にパネル又は網目部材が介在するため、受ける水平力に対して内フレームの剛性、耐力を向上させることができる。また、パネル又は網目部材の材質や配置などを任意に設定することによってデザイン性が向上する。
Moreover, in the earthquake-proof reinforcement structure of the building which concerns on this invention, it is preferable that the mesh member which makes | forms a plate-shaped panel or mesh shape is integrated inside the inner frame.
In the present invention, since a panel or mesh member is interposed inside the inner frame, the rigidity and proof stress of the inner frame can be improved with respect to the horizontal force received. In addition, the design is improved by arbitrarily setting the material and arrangement of the panel or mesh member.

以下、本発明の第一の実施の形態による建築物の耐震補強構造について、図1に基づいて説明する。
図1は第一の実施の形態による耐震補強体1を示す立面図である。
図1に示すように、本第一の実施の形態による建築物の耐震補強構造は、柱や梁からなる架構20に囲まれた構面R内に耐震補強体1を構築するものである。
Hereinafter, the earthquake-proof reinforcement structure of the building by 1st embodiment of this invention is demonstrated based on FIG.
FIG. 1 is an elevation view showing a seismic reinforcement 1 according to the first embodiment.
As shown in FIG. 1, the seismic reinforcement structure for a building according to the first embodiment is a construction in which a seismic reinforcement body 1 is constructed in a construction surface R surrounded by a frame 20 composed of columns and beams.
図1に示すように、耐震補強体1は、構面R内に組み込まれて四角形に枠組みされた外フレーム2と、外フレーム2の内周から所定の間隔を空けて四角形に枠組みされた内フレーム3と、一端4aを外フレーム2の角部2aに他端4bを内フレーム3の角部3aに固定させて斜め方向に配置した斜め連結材4とから概略構成されている。このとき耐震補強体1は、鉛直方向をなす中心線に対して線対称に形成されている。
なお、斜め連結材4は、H型鋼材やL型鋼材などの一般的な鋼材のほか、PC鋼棒や高耐力鋼などの高耐力、高剛性を有する部材を使用してもよい。
そして、斜め連結材4と外、内フレーム2、3との固定は、例えば繋ぎ材として鋼板(図示省略)を設けて、ボルト締結又は溶接などによる固定手段によって行われている。
As shown in FIG. 1, the seismic reinforcing body 1 includes an outer frame 2 incorporated in the construction surface R and framed in a quadrangular shape, and an inner frame framed in a rectangular shape at a predetermined interval from the inner periphery of the outer frame 2. The frame 3 and the diagonal connecting member 4 are arranged in an oblique direction with one end 4 a fixed to the corner 2 a of the outer frame 2 and the other end 4 b fixed to the corner 3 a of the inner frame 3. At this time, the seismic reinforcement body 1 is formed in line symmetry with respect to a center line that forms a vertical direction.
The diagonal connecting member 4 may be a general steel material such as an H-shaped steel material or an L-shaped steel material, or a member having high strength and high rigidity such as a PC steel rod or high strength steel.
The diagonal connecting member 4 and the outer and inner frames 2 and 3 are fixed by, for example, a fixing means such as a steel plate (not shown) as a connecting member and bolt fastening or welding.
また、図1に示すように、耐震補強体1と架構20との接続は、外フレーム2と架構20との間に隙間21を設け、この隙間21に例えば図示しないアンカーボルト或いはアンカーボルト無しの無収縮モルタルによる施工によって行われる。このような構造により、架構20に作用する水平力は、隙間21を介して耐震補強体1に伝達されることになる。   Also, as shown in FIG. 1, the seismic reinforcement 1 and the frame 20 are connected by providing a gap 21 between the outer frame 2 and the frame 20. It is done by construction with non-shrink mortar. With such a structure, the horizontal force acting on the frame 20 is transmitted to the seismic reinforcement body 1 through the gap 21.
図1に示すように、耐震補強体1は、外フレーム2の内側において、内フレーム3を介して斜め方向に配置される斜め連結材4が従来のブレースと同等の機能をなしている。つまり、地震時に水平力が建築物に作用するとき、外フレーム2には架構20より水平力が伝達され、外フレーム2の内側には、この水平力に対抗する水平耐力が斜め連結材4と内フレーム3とによって与えられている。
そして、斜め連結材4にPC鋼棒や高耐力鋼などを使用した場合には、部材内にプレストレスを導入させて初期張力(引張力)を予め与えておくことができ、より耐震性を向上させた耐震補強構造を実現することができる。
As shown in FIG. 1, in the seismic reinforcement body 1, an oblique connecting member 4 disposed in an oblique direction via an inner frame 3 inside the outer frame 2 has a function equivalent to that of a conventional brace. In other words, when a horizontal force acts on the building during an earthquake, a horizontal force is transmitted from the frame 20 to the outer frame 2, and a horizontal proof force against the horizontal force is applied to the outer frame 2 with the diagonal connecting member 4. Given by the inner frame 3.
When a PC steel bar or high strength steel is used for the diagonal connecting material 4, prestress can be introduced into the member and an initial tension (tensile force) can be given in advance, thereby further improving earthquake resistance. An improved seismic reinforcement structure can be realized.
また、図1に示すように、構面R内には内外フレーム2、3及び斜め連結材4に囲われた開口部5が形成されている。そして、内フレーム3の内側及びその両隣の開口部5には、内フレーム3の縦材3bと外フレーム2の縦材2bとが略平行に配設されることで、有効領域M1、M2が形成されている。この有効領域M1、M2は、従来の耐震補強構造と比較して大きな開口率をなす四角形のスペースであり、用途上、有効活用できるスペースとなっている。なお、この有効領域M1、M2の大きさは、内フレーム3の縦横材の長さを変えることで任意に変更することができる。   Further, as shown in FIG. 1, an opening 5 surrounded by the inner and outer frames 2 and 3 and the oblique connecting member 4 is formed in the composition surface R. In addition, the vertical members 3b of the inner frame 3 and the vertical members 2b of the outer frame 2 are disposed substantially parallel to the inner frame 3 and the openings 5 adjacent to the inner frame 3, so that the effective regions M1 and M2 are provided. Is formed. These effective areas M1 and M2 are rectangular spaces having a large aperture ratio as compared with the conventional seismic reinforcement structure, and are spaces that can be effectively used for applications. The sizes of the effective areas M1 and M2 can be arbitrarily changed by changing the lengths of the vertical and horizontal members of the inner frame 3.
上述した本第一の実施の形態による建築物の耐震補強構造では、外フレーム2の内側で斜め連結材4を斜め方向に配置して内フレーム3に連結することで、従来の鉄骨ブレースと同様の耐震構造を実現できると共に、用途として有効活用できる有効領域M1、M2を確保することができる。このため、構面R内において、例えば出入口や廊下(通路)、大きな窓といった用途に合わせてデザインすることができ、デザインの幅を広げることができる。
また、要求される耐震補強の耐力や性能などの条件に合わせて、内フレーム3の大きさや配置、鋼材の断面の大きさ、部材の種類などを検討変更することができ、フレキシブルな設計が可能となる。
In the earthquake-proof reinforcement structure for a building according to the first embodiment described above, the diagonal connecting member 4 is arranged in an oblique direction inside the outer frame 2 and is connected to the inner frame 3 so that it is similar to the conventional steel brace. The effective regions M1 and M2 that can be effectively used as applications can be secured. For this reason, in the construction surface R, it can design according to uses, such as an entrance / exit, a corridor (passage), and a big window, and can expand the width | variety of a design.
In addition, the size and arrangement of the inner frame 3, the size of the cross section of the steel material, the type of member, etc. can be examined and changed according to the required conditions such as the strength and performance of the seismic reinforcement required, enabling flexible design It becomes.
