特開２０１３－１２２１５９号公報JP 2013-122159 A

従来の、建物柱の補助構造を構成する補助部材は、中空の箱状体からなるものである。
このため、大地震時に、設置した建物柱の補助部材が荷重を受けたときに、その力を負担するのは両側面部のみであり、大きな水平荷重を負担することはできなかった。
また、地震時の横揺れにより、建物が水平方向に変位すると、補助部材も水平方向に変形してしまうため、鉛直荷重に対する負担能力を喪失するおそれもあった。 A conventional auxiliary member that constitutes an auxiliary structure for a building pillar consists of a hollow box-like body.
For this reason, when an auxiliary member of a building pillar receives a load during a large earthquake, the load is borne only by the side surfaces, and a large horizontal load cannot be borne.
In addition, if the building is horizontally displaced by the rolling motion of an earthquake, the auxiliary members will also be deformed horizontally, and there is a risk that the ability to bear the vertical load will be lost.

本発明は、水平剛性を向上させることによって建物の水平変位を抑制し、同時に、鉛直方向の耐力向上に加え、水平方向においても強度の高い、建物柱の機能を補完することのできる建物柱の補助部材を提供することを目的とする。 The present invention suppresses the horizontal displacement of the building by improving the horizontal rigidity, and at the same time, in addition to improving the strength in the vertical direction, it is also strong in the horizontal direction. The object is to provide an auxiliary member.

上記目的を達成するためになされた本発明の建物柱の補助部材は、鉛直方向に延びる第一側面部と、前記第一側面部の上端縁に連続して水平に延びる上面部と、前記第一側面部の下端縁に連続して水平に延びる下面部と、前記上面部及び前記下面部の端縁同士を連結して前記第一側面部と平行に延びる第二側面部と、前記第一側面部、前記上面部、前記下面部、及び前記第二側面部と直交するとともに、前記第一側面部、前記上面部、前記下面部、及び前記第二側面部のうち、少なくともいずれか二面の内面に固定するリブと、からなる。
前記リブは、前記第一側面部、前記上面部、前記下面部、及び前記第二側面部の内面に四周を固定し、前記リブの一部を切り欠いて開口部を設けてもよい。
前記リブの中央に矩形状又は円状の開口部を設けてもよい。
前記リブは、前記第一側面部、前記上面部、前記下面部、及び前記第二側面部のうち、直交するいずれか二面の内面に固定する、正面視三角形状としてもよい。 An auxiliary member for a building pillar of the present invention, which has been made to achieve the above object, comprises a vertically extending first side surface portion, an upper surface portion extending horizontally continuously from the upper edge of the first side surface portion, and the second side surface portion. a lower surface portion that extends horizontally continuously from a lower edge of one side surface portion; a second side surface portion that connects edges of the upper surface portion and the lower surface portion and extends in parallel with the first side surface portion; At least two surfaces of the first side surface portion, the top surface portion, the bottom surface portion, and the second side surface portion, which are orthogonal to the side surface portion, the top surface portion, the bottom surface portion, and the second side surface portion. ribs fixed to the inner surface of the
Four circumferences of the rib may be fixed to the inner surfaces of the first side surface portion, the upper surface portion, the lower surface portion, and the second side surface portion, and an opening may be provided by cutting out a portion of the rib.
A rectangular or circular opening may be provided in the center of the rib.
The rib may have a triangular shape in front view and is fixed to the inner surfaces of any two of the first side surface portion, the upper surface portion, the lower surface portion, and the second side surface portion that are perpendicular to each other.

本発明は、上記した課題を解決するための手段により、次のような効果の少なくとも一つを得ることができる。
（１）補助部材の内面に設けたリブが、補助部材の各面に作用する力を負担するため、強度の高い耐震補助構造となる。
（２）リブに開口部を設けることにより、一方の開口面からリブを挟んだ他方側の連結材を取り付けることができる。
（３）リブの開口部を所定の形状とすることで、補助部材を積層して構成された架構が幾何学的模様を創出するため、ファサードやピロティに新たな美感を与えることができる。 The present invention can obtain at least one of the following effects by the means for solving the above problems.

以下、図面を参照しながら本発明の建物の補助部材を詳細に説明する。 Hereinafter, the auxiliary member of the building of the present invention will be described in detail with reference to the drawings.

［実施例１］
（１）建物柱の補助部材
本発明の建物柱の補助部材１は、鉛直方向に延びる第一側面部１１と、この第一側面部１１の上端縁に連続して水平に延びる上面部１２と、第一側面部１１の下端縁に連続して上面部１２と平行に延びる下面部１３と、上面部１２及び下面部１３の端縁同士を連結して第一側面部１１と平行に延びる第二側面部１４と、を有して、側方に開口を有する中空の立方体であり、鋼板により構成する（図１）。 [Example 1]
(1) Auxiliary member for building pillar The auxiliary member 1 for building pillar of the present invention comprises a first side surface portion 11 extending in the vertical direction and an upper surface portion 12 extending horizontally continuously from the upper edge of the first side surface portion 11. a lower surface portion 13 that extends parallel to the upper surface portion 12 continuously from the lower edge of the first side surface portion 11; It is a hollow cube having two side faces 14 and openings on the sides, and is made of steel plate (FIG. 1).

（２）リブ
補助部材１は、第一及び第二の側面部１１、１４と上面部１２及び下面部１３の各内面に、四周を溶接により固定するリブ１５を有する。
リブ１５は鋼板からなり、四辺の中央を頂点とした矩形状の開口部１５１を有する。 (2) Ribs Auxiliary member 1 has ribs 15 fixed on the inner surfaces of first and second side surface portions 11 and 14 and upper surface portion 12 and lower surface portion 13 by welding.
The rib 15 is made of a steel plate and has a rectangular opening 151 with the center of the four sides as the apex.

（３）耐震補助構造
本発明の補助部材１を用いた建物の耐震補助構造は、建物の梁間に設けるものであり、本実施例においては、コンクリートからなるベース２上に複数の補助部材１を並列および積層して構成する（図２）。
本発明の補助部材１を用いた耐震補助構造を提供する建物は、例えば、鉄骨造の倉庫や事務所ビル等の既存建物である。本実施例の建物は柱３の上下に梁４と基礎部５を有しており、柱３や梁４の耐力が不足する場合において、該耐力を補うための耐震補助構造となる。
基礎部５の上部にはベース２を形成する。
そして、補助部材１をベース２上に並列および積層し、接する面のボルト挿通孔１１Ａ、１２Ａ、１３Ａ、１４Ａにボルト及びナットにより構成する連結材１６のボルトを挿通し、ナットを螺合して連結する。最上段の補助部材１の上面部１２は梁４と連結する。
本発明の補助部材１はリブ１５に開口部１５１を有するため、補助部材１の一方の開口面からリブ１５を挟んだ他方側の連結材１６を取り付けることができる。このため、補助部材１の片側の開口面が塞がるような建物にも適用することができる。 (3) Earthquake-Resistant Auxiliary Structure The earthquake-resistant auxiliary structure of a building using the auxiliary member 1 of the present invention is provided between the beams of a building. Constructed in parallel and stacked (Fig. 2).
The building that provides the earthquake-resistant auxiliary structure using the auxiliary member 1 of the present invention is, for example, an existing building such as a steel-framed warehouse or office building. The building of this embodiment has beams 4 and foundations 5 above and below columns 3. When the bearing strength of the columns 3 and beams 4 is insufficient, the building serves as an auxiliary seismic resistance structure for compensating for the bearing strength.
A base 2 is formed on the upper portion of the base portion 5 .
Then, the auxiliary members 1 are arranged in parallel and stacked on the base 2, and the bolts of the connecting member 16 composed of bolts and nuts are inserted into the bolt insertion holes 11A, 12A, 13A, and 14A on the contacting surfaces, and the nuts are screwed together. connect. The upper surface portion 12 of the uppermost auxiliary member 1 is connected to the beam 4 .
Since the auxiliary member 1 of the present invention has the opening 151 in the rib 15 , the connecting member 16 on the other side of the auxiliary member 1 sandwiching the rib 15 can be attached from one opening surface. Therefore, it can be applied to a building in which one side of the opening of the auxiliary member 1 is closed.

（４）耐震補助構造の作用
地震等によって建物に力が作用すると、柱３や梁４に曲げ変形及びせん断変形が生じたときに、梁４及び基礎部５に固定した耐震補助構造の補助部材１が弾性変形するとともに、建物の鉛直荷重を支持し、建物に生じる変形を抑制する。
また、柱３崩壊時には耐震補助構造が柱３の代わりに軸力を支持する。そして、受ける軸力が大きくなると、積層した補助部材１が層ごとに変形し、衝撃を吸収する。積層した補助部材１は、層崩壊に至る段階で各層ごとに順番に変形するため、急激な層崩壊を抑制する。
補助部材１の内面に設けたリブ１５が、補助部材１の各面に作用する力を負担するため、補助部材１の変形を抑制し、強度の高い耐震補助構造となる。 (4) Operation of the earthquake-resistant auxiliary structure When force acts on the building due to an earthquake, etc., the auxiliary members of the earthquake-resistant auxiliary structure fixed to the beams 4 and the foundation 5 when bending deformation and shear deformation occur in the columns 3 and beams 4. 1 elastically deforms, supports the vertical load of the building, and suppresses the deformation of the building.
Also, when the column 3 collapses, the earthquake-resistant auxiliary structure supports the axial force instead of the column 3. When the axial force received increases, each layer of the laminated auxiliary member 1 deforms and absorbs the impact. Since the laminated auxiliary member 1 is deformed in order for each layer in the stage leading to layer collapse, rapid layer collapse is suppressed.
Since the ribs 15 provided on the inner surface of the auxiliary member 1 bear the force acting on each surface of the auxiliary member 1, the deformation of the auxiliary member 1 is suppressed, resulting in a high-strength earthquake-resistant auxiliary structure.

［その他の実施例］
（１）開口部の形状
上述の実施例では、リブ１５の開口部１５１を矩形状としたが、円状としてもよい（図３）。また、リブ１５の四隅に切り抜き１５２を設けてもよい。切り抜き１５２を設けることにより、リブ１５を補強部材１の内周面に固定する際に、補強部材１の内周面の角部に寸法誤差があっても、リブ１５を加工することなく補強部材１の内周に収めることができる。また、切り抜き１５２を設けることで溶接長さも短くなり、端部の溶接も容易に行うことができ、施工コストが低減される。 [Other Examples]
(1) Shape of Opening In the above embodiment, the opening 151 of the rib 15 is rectangular, but may be circular (FIG. 3). Also, cutouts 152 may be provided at the four corners of the rib 15 . By providing the cutout 152, when fixing the rib 15 to the inner peripheral surface of the reinforcing member 1, even if there is a dimensional error at the corner of the inner peripheral surface of the reinforcing member 1, the reinforcing member can be fixed without processing the rib 15. 1 can be accommodated. In addition, by providing the cutout 152, the welding length is shortened, and the welding of the ends can be easily performed, thereby reducing the construction cost.

（２）リブの形状
また、リブ１５は、上面部１２（下面部１３でもよい）と第二側面部１４（第一側面部１１でもよい）の内面に固定する三角形状（図４（ａ））でもよいし、例えば円弧状に一部を切り欠く形状（図４（ｂ））としてもよい。 (2) Shape of Rib In addition, the rib 15 has a triangular shape (FIG. 4(a) ), or, for example, a shape in which a part is notched in an arc shape (FIG. 4B).

このようにリブ１５の開口部１５１を所定の形状とすることにより、補助部材１を積層して構成された架構が幾何学的模様を創出するため（図２）、建物のファサードやピロティに耐震補助構造による新たな美感を与えることができる。 By forming the openings 151 of the ribs 15 into a predetermined shape in this way, the frame constructed by laminating the auxiliary members 1 creates a geometric pattern (Fig. 2). A new aesthetic feeling can be given by the auxiliary structure.
