Are provided upright at the end of the base plate 18 so as to face the outer side surfaces of the ends 58 and 60. The fixing plates 20 are arranged on both sides of the ends 58 and 60 of the frame member 26 (the lower frame 38) with respect to the out-of-plane direction 64 of the beam-column frame 12. The fixed plate 20 and the ends 58 and 60 of the frame member 26 (the lower frame 38) are joined and connected by the bolts 22 and the nuts 24.

次に、本発明の実施形態に係る柱梁架構の補強構造の作用と効果について説明する。   Next, the operation and effect of the column-beam frame reinforcing structure according to the embodiment of the present invention will be described.

本実施形態の柱梁架構の補強構造１０では、図１に示すように、補強構造体１４を柱梁架構１２の架構内に配置することにより、柱梁架構１２のせん断耐力を高めて柱梁架構１２を補強することができる。   In the reinforcement structure 10 of the beam-column frame according to the present embodiment, as shown in FIG. 1, by arranging the reinforcement structure 14 in the frame of the beam-column frame 12, the shear strength of the beam-column frame 12 is increased, and The frame 12 can be reinforced.

また、図１に示すように、枠部材２６の下枠３８の横方向中央部に除去部１６を設けることにより、柱梁架構１２の架構面の横方向中央部に、ドアや通路等を設けるための段差のない開口部６２を形成することができる。   Also, as shown in FIG. 1, by providing the removing portion 16 at the lateral center of the lower frame 38 of the frame member 26, a door, a passage, and the like are provided at the lateral center of the frame surface of the beam-column frame 12. Opening 62 without any step can be formed.

さらに、図１に示すように、除去部１６に面する枠部材２６（下枠３８）の端部５８、６０とベースプレート１８の端部を固定プレート２０により連結して連続した枠を形成することにより、除去部１６を設けることによる、枠部材２６と鉄骨ブレース部材２８とから構成される補強構造体１４の靱性の低下を抑制することができる。   Further, as shown in FIG. 1, the ends 58 and 60 of the frame member 26 (lower frame 38) facing the removing portion 16 and the ends of the base plate 18 are connected by the fixing plate 20 to form a continuous frame. Accordingly, it is possible to suppress a decrease in the toughness of the reinforcing structure 14 including the frame member 26 and the steel frame brace member 28 due to the provision of the removal portion 16.

また、図１に示すように、補強部材としての鉄骨ブレース部材２８によるせん断抵抗力を柱梁架構１２全体に行き渡らせることができる。本実施形態においては、鉄骨ブレース部材２８によるせん断抵抗力が柱梁架構１２の一部に集中して伝達されることにより柱梁架構１２の一部が局所的に破壊されることを、抑制することができる。   In addition, as shown in FIG. 1, the shearing resistance of the steel brace member 28 as a reinforcing member can be spread over the entire column-beam frame 12. In the present embodiment, local destruction of a portion of the beam-and-column frame 12 due to the shear resistance force of the steel frame brace member 28 being transmitted intensively to a portion of the beam-and-column frame 12 is suppressed. be able to.

さらに、図３に示すように、枠部材２６（下枠３８）の端部５８、６０の外部側面に対向するようにしてベースプレート１８の端部に立設された固定プレート２０を、枠部材２６（下枠３８）の端部５８、６０の外部側面に固定するので、溶接以外の方法（例えば、本実施形態で示したボルト固定）によって、ベースプレート１８の端部を枠部材２６（下枠３８）の端部５８、６０に固定することができる。   Further, as shown in FIG. 3, the fixed plate 20 erected at the end of the base plate 18 so as to face the outer side surfaces of the ends 58 and 60 of the frame member 26 (the lower frame 38) is attached to the frame member 26. Since the outer frame 58 is fixed to the outer side surfaces of the ends 58 and 60 of the (lower frame 38), the end of the base plate 18 is fixed to the frame member 26 (lower frame 38) by a method other than welding (for example, bolt fixing shown in the present embodiment). ) At the ends 58, 60.

また、図１及び図２に示すように、除去部１６及びベースプレート１８の長さの誤差や、ベースプレート１８への固定プレート２０の取り付け誤差等を許容して、ベースプレート１８の端部を枠部材２６（下枠３８）の端部５８、６０に固定することができる。   Also, as shown in FIGS. 1 and 2, the end of the base plate 18 is fixed to the frame member 26 by allowing an error in the length of the removing portion 16 and the base plate 18 and an error in attaching the fixing plate 20 to the base plate 18. (Lower frame 38).

以上、本発明の実施形態について説明した。   The embodiment of the invention has been described.

なお、本実施形態では、図３に示すように、枠部材２６（下枠３８）の端部５８、６０の外部側面に対向するようにしてベースプレート１８の端部に固定プレート２０を立設させた例を示したが、図４の側面断面図に示すように、固定プレート２０は、枠部材２６（下枠３８）の端部５８、６０の内部側面に対向するようにしてベースプレート１８の端部に立設させてもよい。また、固定プレート２０は、ベースプレート１８の端部以外の位置に立設させてもよい。   In the present embodiment, as shown in FIG. 3, the fixed plate 20 is erected at the end of the base plate 18 so as to face the outer side surfaces of the ends 58 and 60 of the frame member 26 (the lower frame 38). As shown in the side sectional view of FIG. 4, the fixing plate 20 faces the inner side surfaces of the ends 58 and 60 of the frame member 26 (the lower frame 38). It may be erected in the section. Further, the fixing plate 20 may be erected at a position other than the end of the base plate 18.

また、本実施形態では、図３に示すように、固定プレート２０と枠部材２６（下枠３８）の端部５８、６０とを接合し連結する連結手段を、ボルト２２及びナット２４とした例を示したが、連結手段は、固定プレート２０と枠部材２６（下枠３８）の端部５８、６０を接合し連結することができればよく、例えば、溶接や接着剤としてもよい。   Further, in the present embodiment, as shown in FIG. 3, an example in which the bolt 22 and the nut 24 are used as connecting means for joining and connecting the fixing plate 20 and the ends 58 and 60 of the frame member 26 (the lower frame 38). However, the connecting means only needs to be able to join and connect the fixing plate 20 and the ends 58 and 60 of the frame member 26 (the lower frame 38), and may be, for example, welding or an adhesive.

さらに、本実施形態では、図１及び図３に示すように、枠部材２６を構成する下枠３８、上枠４０、左側枠４２、及び右側枠４４をＨ形鋼とした例を示したが、下枠３８、上枠４０、左側枠４２、及び右側枠４４を片刃落しにした形鋼（Ｈ形鋼の一方のフランジのウェブ付近から柱梁架構１２へ向かう部分を無くした形状の形鋼）として、施工性を向上させてもよい。   Further, in the present embodiment, as shown in FIGS. 1 and 3, an example is shown in which the lower frame 38, the upper frame 40, the left frame 42, and the right frame 44 constituting the frame member 26 are H-shaped steel. , The lower frame 38, the upper frame 40, the left frame 42, and the right frame 44, each of which has a single-cut edge (a shape steel having a portion from the vicinity of the web of one flange of the H-section steel toward the beam-to-column frame 12). ), The workability may be improved.

また、本実施形態では、図１に示すように、枠部材２６の内側に逆Ｖ字状に配置された鉄骨ブレース部材２８を補強部材とした例を示したが、図５の正面図に示す柱梁架構の補強構造６６のように、枠部材２６の内側にＶ字状に配置された鉄骨ブレース部材２８を補強部材としてもよい。柱梁架構の補強構造６６では、除去部１６が下枠３８の横方向端部に形成されている。すなわち、除去部１６は、下枠３８の一部が除去されて形成されている。このようにすれば、柱梁架構１２の架構面の横方向端部に、ドアや通路等を設けるための段差のない開口部６２を形成することができる。   Further, in the present embodiment, as shown in FIG. 1, an example is shown in which the steel brace member 28 arranged in an inverted V-shape inside the frame member 26 is used as a reinforcing member, but is shown in the front view of FIG. 5. As in the case of the reinforcing structure 66 of the beam-column structure, the steel frame brace member 28 arranged in a V shape inside the frame member 26 may be used as the reinforcing member. In the reinforcement structure 66 of the column-beam frame, the removing portion 16 is formed at the lateral end of the lower frame 38. That is, the removal portion 16 is formed by removing a part of the lower frame 38. In this way, a stepless opening 62 for providing a door, a passage, or the like can be formed at a lateral end of the frame surface of the beam-column frame 12.

さらに、本実施形態では、図１に示すように、補強部材を鉄骨ブレース部材２８とした例を示したが、補強部材は、柱梁架構１２に生じるせん断力に抵抗可能な部材であればよい。例えば、図６の正面図に示す柱梁架構の補強構造６８のように、補強部材を鋼製の耐震壁７０としてもよい。   Further, in the present embodiment, as shown in FIG. 1, an example in which the reinforcing member is the steel frame brace member 28 has been described, but the reinforcing member may be any member that can resist the shearing force generated in the beam-column frame 12. . For example, the reinforcing member may be a steel earthquake-resistant wall 70 as in a reinforcing structure 68 of a beam-column frame shown in the front view of FIG.

また、本実施形態では、柱梁架構１２を鉄筋コンクリート造とした例を示したが、柱梁架構は、鉄筋コンクリート造、鉄骨造、鉄骨鉄筋コンクリート造、ＣＦＴ造（Concrete-Filled Steel Tube：充填形鋼管コンクリート構造）、それらの混合構造など、さまざまな構造や規模のものであってもよい。   Further, in the present embodiment, an example in which the beam-to-column frame 12 is made of reinforced concrete is shown. Structures), and various structures and scales such as a mixed structure thereof.

以上、本発明の実施形態について説明したが、本発明はこうした実施形態に何等限定されるものでなく、本発明の要旨を逸脱しない範囲において、種々なる態様で実施し得ることは勿論である。   Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments at all, and it is needless to say that the present invention can be implemented in various modes without departing from the gist of the present invention.
