A first left brace that is joined to the upper beam and a second left brace that is joined to the upper beam to form a V-shaped left brace body having left end joints that are end joined to each other, and joined to the left end joint The left connecting brace is joined to the lower end of the left column, and the first right brace joined to the right joint and the second right brace joined to the upper beam are joined to each other at the right end. The present invention relates to a reinforcement structure for a column-beam frame, which constitutes a V-shaped right brace body having a joint portion, and a right connecting brace joined to the right end joint portion thereof is joined to the lower end portion of the right column.

実用新案登録第３１９７７３４号公報（特に、図７参照）Utility model registration No. 3197734 (see especially FIG. 7)

しかしながら、上記公報に開示の従来技術では、左連結ブレースと右連結ブレースが、それぞれ左右のブレース体を構成するブレースと同じ材料、具体的には、同じ丸鋼で構成されているので、強度的に問題があり、この点に改良の余地がある。
すなわち、上述した柱梁架構の補強構造では、例えば、地震によって上部梁が左右に揺れると、上部梁の高さが低くなり、左右のブレース体や連結ブレースに大きな圧縮力が作用することになる。その際、左右のブレース体は、上部梁と伴に三角形に構成されるので比較的丈夫であり、その結果、左右の連結ブレースに大きな軸力が集中的に作用して座屈する可能性があり、この点に改良の余地がある。 However, in the prior art disclosed in the above publication, the left connecting brace and the right connecting brace are made of the same material as the brace forming the left and right brace bodies, specifically, the same round steel, so that the strength is improved. However, there is room for improvement in this respect.
That is, in the above-described reinforcement structure of the column-beam structure, for example, when the upper beam sways to the left or right due to an earthquake, the height of the upper beam decreases, and a large compressive force acts on the left and right brace bodies and the connecting brace. .. At that time, the left and right brace bodies are relatively strong because they are configured in a triangular shape together with the upper beam, and as a result, large axial forces may concentrate on the left and right connecting braces, causing buckling. , There is room for improvement in this respect.

本発明は、このような従来の問題点に着目したもので、その目的は、たとえ地震によって左右の連結ブレースに大きな軸力が集中的に作用しても、左右の連結ブレースの座屈を回避することができ、補強構造全体としての強度向上も図り得る柱梁架構の補強構造を提供することにある。   The present invention focuses on such a conventional problem, and an object thereof is to avoid buckling of the left and right connecting braces even if a large axial force is concentrated on the left and right connecting braces due to an earthquake. Another object of the present invention is to provide a reinforcement structure of a column-beam frame structure which can be improved and can improve the strength of the entire reinforcement structure.

本発明の第１特徴構成は、左柱の上部が、左接合部を介して上部梁に接合され、右柱の上部が、右接合部を介して前記上部梁に接合される柱梁架構において、前記左接合部に接合の第１左ブレースと前記上部梁に接合の第２左ブレースが、互いに端部接合された左端部接合部を有するＶ字状の左ブレース体を構成し、その左端部接合部に接合の左連結ブレースが、前記左柱の下端部に接合されるとともに、前記右接合部に接合の第１右ブレースと前記上部梁に接合の第２右ブレースが、互いに端部接合された右端部接合部を有するＶ字状の右ブレース体を構成し、その右端部接合部に接合の右連結ブレースが、前記右柱の下端部に接合される柱梁架構の補強構造であって、前記左連結ブレースと右連結ブレースが、それぞれ座屈補剛ブレースで構成される点にある。   A first characteristic configuration of the present invention is a post-beam structure in which an upper part of a left pillar is joined to an upper beam through a left joint portion, and an upper part of a right pillar is joined to the upper beam through a right joint portion. A first left brace joined to the left joint and a second left brace joined to the upper beam constitute a V-shaped left brace body having left end joints joined to each other at their left ends. A left connecting brace joined to the joint portion is joined to a lower end portion of the left column, and a first right brace joined to the right joint portion and a second right brace joined to the upper beam are end portions of each other. A V-shaped right brace body having a joined right end joint portion, and a right connecting brace joined to the right end joint portion thereof is joined to the lower end portion of the right pillar by a reinforcing structure of a beam-column structure. The left connecting brace and the right connecting brace are buckling stiffening brace, respectively. In the point made.

本構成によれば、従来と同様に、柱梁架構の中央部に大きなスペースを確保することができ、例えば、そのスペースを出入口として有効に使用することが可能となる。
それに加えて、左連結ブレースと右連結ブレースが、それぞれ座屈補剛ブレースで構成されるので、例えば、地震によって上部梁が左右に揺れて左右の連結ブレースに大きな軸力が集中的に作用しても、左右の連結ブレースが座屈することはなく、補強構造全体としての強度も大幅に向上する。 According to this configuration, a large space can be secured in the central portion of the beam-column structure as in the conventional case, and for example, the space can be effectively used as a doorway.
In addition, the left connecting brace and the right connecting brace are each made up of buckling stiffening braces, so for example, an upper beam sways left and right due to an earthquake and large axial forces concentrate on the left and right connecting braces. However, the left and right connecting braces do not buckle, and the strength of the reinforcing structure as a whole is significantly improved.

本発明の第２特徴構成は、前記左右の連結ブレースを構成する座屈補剛ブレースが、芯材としてのＨ形鋼とそのＨ形鋼を収納保持する補剛用の鋼管で構成される点にある。   A second characteristic configuration of the present invention is that the buckling stiffening brace forming the left and right connecting brace is composed of an H-shaped steel as a core material and a stiffening steel pipe for storing and holding the H-shaped steel. It is in.

本構成によれば、左右の連結ブレースを構成する座屈補剛ブレースが、Ｈ形鋼と補剛用の鋼管で構成されるので、どちらの材料も比較的入手し易く、かつ、座屈補剛ブレースの作製も比較的容易となる。   According to this configuration, since the buckling stiffening brace that constitutes the left and right connecting braces is composed of the H-section steel and the stiffening steel pipe, both materials are relatively easy to obtain and the buckling stiffening is relatively easy. Rigid braces are also relatively easy to make.

本発明の第３特徴構成は、前記左端部接合部と右端部接合部とに亘って、繋ぎ材が接合される点にある。   A third characteristic configuration of the present invention is that a connecting member is joined across the left end joint portion and the right end joint portion.

本構成によれば、繋ぎ材が、左ブレース体の左端部接合部と右ブレース体の右端部接合部とに亘って接合されるので、繋ぎ材によって左端部接合部と右端部接合部が強化され、補強構造の更なる強化が可能となり、更に、その繋ぎ材をシャッターなどの扉を設置する際の下地材として使用することも可能となる。   According to this configuration, since the joining material is joined over the left end joining portion of the left brace body and the right end joining portion of the right brace body, the joining material strengthens the left end joining portion and the right end joining portion. Therefore, the reinforcing structure can be further strengthened, and the connecting material can be used as a base material when installing a door such as a shutter.

本発明の第４特徴構成は、前記左端部接合部に接合の左補助ブレースと前記右端部接合部に接合の右補助ブレースが、それぞれ前記柱梁架構の構面外の同じ方向に向けて斜め上方に延出されて建物の躯体に接合される点にある。   A fourth characteristic configuration of the present invention is that the left auxiliary brace joined to the left end joint and the right auxiliary brace joined to the right end joint are slanted toward the same direction outside the surface of the column beam frame. It is located at the point where it extends upward and is joined to the body of the building.

本構成によれば、左端部接合部に接合の左補助ブレースと右端部接合部に接合の右補助ブレースが、それぞれ柱梁架構の構面外の同じ方向に向けて斜め上方に延出されて建物の躯体に接合されるので、これら左右の補助ブレースによって左端部接合部と右端部接合部の構面外方向への変形が抑制され、その結果、左端部接合部と右端部接合部の更なる強化が可能となり、補強構造全体が更に一層強化される。   According to this configuration, the left auxiliary brace joined to the left end joint and the right auxiliary brace joined to the right end joint are respectively extended obliquely upward in the same direction outside the surface of the column beam frame. Since they are joined to the frame of the building, these left and right auxiliary braces suppress the deformation of the left end joint and the right end joint in the out-of-plane direction, and as a result, the left end joint and the right end joint are not changed. Can be strengthened, and the entire reinforcing structure is further strengthened.
