Description

本発明は、建物柱の補助部材であって、積層して組み立てることで、地震時に柱が負担していた鉛直荷重を支持する機能を喪失した場合に、柱の機能を補完する働きを持つものに関する。 This invention relates to auxiliary components for building columns that, when assembled in layers, complement the function of the columns when they lose their ability to support the vertical load that they bear during an earthquake.

従来、柱がその機能を喪失した場合を想定して設置する建物柱の耐震補助構造としては、建物の基礎梁とその上部梁の間に、補助部材を積層して組み立てて設置する構造が使われている。
この補助構造は、建物の柱が破損した時に、積層して組み立てた補助部材により、柱が負担していた鉛直荷重を引き受けるもので、これによって大地震の際に建物柱が損傷した場合にあっても、建物居住者の避難空間と避難時間を確保することができる。 Conventionally, earthquake-resistant auxiliary structures for building columns, which are installed in anticipation of the possibility that the columns may lose their function, have been constructed by stacking and assembling auxiliary members between the building's foundation beams and their upper beams.
This auxiliary structure is designed so that when a building's pillars are damaged, the vertical load that had been borne by the pillars is taken over by the stacked auxiliary components. This ensures that the building's occupants have enough space and time to evacuate, even if the building's pillars are damaged during a major earthquake.

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。 Conventionally, auxiliary members constituting the auxiliary structure of a building column are made of hollow box-shaped bodies.
As a result, when the auxiliary members of the installed building columns were subjected to a load during a major earthquake, the force was only borne by the two side sections, and they were unable to bear large horizontal loads.
In addition, if the building is displaced horizontally due to lateral shaking during an earthquake, the auxiliary members will also deform horizontally, which could result in them losing their ability to bear vertical loads.

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、からなり、前記上面部及び前記下面部には、積層した際に接する面を相互に連結するためのボルト挿通孔を有し、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、正面視三角形状とする。
 In order to achieve the above-mentioned object, the auxiliary member for a building column of the present invention comprises a first side portion extending vertically, an upper surface portion extending horizontally continuous with the upper edge of the first side portion, a lower surface portion extending horizontally continuous with the lower edge of the first side portion, a second side portion connecting the edges of the upper surface portion and the lower surface portion and extending parallel to the first side portion, and a rib that is perpendicular to the first side portion, the upper surface portion, the lower surface portion, and the second side portion and is fixed to the inner surfaces of at least any two of the first side portion, the upper surface portion, the lower surface portion, and the second side portion, wherein the upper surface portion and the lower surface portion have bolt insertion holes for connecting the surfaces that come into contact when stacked, and the rib has a triangular shape when viewed from the front and is fixed to the inner surfaces of any two orthogonal surfaces of the first side portion, the upper surface portion, the lower surface portion, and the second side portion.

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。 The auxiliary member for a building column of the present invention, which has been made to achieve the above-mentioned object, comprises a first side portion extending in a vertical direction, an upper surface portion extending horizontally continuous with the upper edge of the first side portion, a lower surface portion extending horizontally continuous with the lower edge of the first side portion, a second side portion connecting the edges of the upper surface portion and the lower surface portion and extending parallel to the first side portion, and a rib that is perpendicular to the first side portion, the upper surface portion, the lower surface portion, and the second side portion and is fixed to the inner surfaces of at least any two of the first side portion, the upper surface portion, the lower surface portion, and the second side portion.
The rib may be fixed around all four sides to inner surfaces of the first side portion, the upper surface portion, the lower surface portion and the second side portion, and an opening may be provided by cutting out a part of the rib.

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。 The building support components of the present invention will be described in detail below 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 column The auxiliary member 1 for a building column of the present invention is a hollow cube having an opening on one side and is made of steel plate, and has a first side portion 11 extending vertically, an upper surface portion 12 extending horizontally and continuing from the upper edge of the first side portion 11, a lower surface portion 13 extending parallel to the upper surface portion 12 and continuing from the lower edge of the first side portion 11, and a second side portion 14 connecting the edges of the upper surface portion 12 and the lower surface portion 13 and extending parallel to the first side portion 11 (Figure 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) Rib The auxiliary member 1 has ribs 15 on the inner surfaces of the first and second side surface portions 11, 14 and the upper and lower surface portions 12, 13, which are fixed around all four peripheries by welding.
The rib 15 is made of a steel plate and has a rectangular opening 151 with vertices at the centers of the four sides.

（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 installed between the beams of a building. In this embodiment, it is constructed by arranging multiple auxiliary members 1 in parallel and stacking them on a base 2 made of concrete (Figure 2).
The building to which the earthquake-resistant auxiliary structure using the auxiliary member 1 of the present invention is applied is, for example, an existing building such as a steel-framed warehouse, office building, etc. The building of this embodiment has beams 4 and foundations 5 above and below columns 3, and serves as an earthquake-resistant auxiliary structure to compensate for the insufficient strength of the columns 3 and beams 4.
A base 2 is formed on the upper part of the foundation portion 5 .
The auxiliary members 1 are then stacked in parallel on the base 2, and the bolts of the connecting members 16 made of bolts and nuts are inserted into the bolt insertion holes 11A, 12A, 13A, 14A of the contacting surfaces, and the nuts are screwed in to connect them. The upper surface 12 of the uppermost auxiliary member 1 is connected to the beam 4.
Since the auxiliary member 1 of the present invention has an opening 151 in the rib 15, the connecting material 16 on the other side of the rib 15 can be attached from one opening surface of the auxiliary member 1. Therefore, the auxiliary member 1 can be applied to buildings in which one opening surface of the auxiliary member 1 is blocked.

（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) Function of earthquake-resistant auxiliary structure When a force acts on a building due to an earthquake or the like, bending and shear deformation occurs in the columns 3 and beams 4, and the auxiliary members 1 of the earthquake-resistant auxiliary structure fixed to the beams 4 and foundation 5 elastically deform, supporting the vertical load of the building and suppressing deformation occurring in the building.
In addition, when the column 3 collapses, the earthquake-resistant auxiliary structure supports the axial force instead of the column 3. When the axial force increases, the stacked auxiliary members 1 deform layer by layer to absorb the impact. The stacked auxiliary members 1 deform in sequence for each layer until the story collapses, suppressing sudden story collapse.
The ribs 15 provided on the inner surface of the auxiliary member 1 bear the forces acting on each surface of the auxiliary member 1, thereby suppressing deformation of the auxiliary member 1 and 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 the opening In the above embodiment, the opening 151 of the rib 15 is rectangular, but it may be circular (FIG. 3). Also, cutouts 152 may be provided at the four corners of the rib 15. By providing the cutouts 152, when the rib 15 is fixed to the inner periphery of the reinforcing member 1, even if there is a dimensional error at the corners of the inner periphery of the reinforcing member 1, the rib 15 can be accommodated within the inner periphery of the reinforcing member 1 without processing the rib 15. Also, providing the cutouts 152 shortens the weld length, facilitating welding of the ends, and reduces construction costs.

（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 the rib The rib 15 may be triangular ( FIG. 4( a) ) fixed to the inner surface of the upper surface portion 12 (or the lower surface portion 13) and the second side surface portion 14 (or the first side surface portion 11), or may be shaped, for example, with a portion cut out in an arc shape ( FIG. 4( b ) ).

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 giving the openings 151 of the ribs 15 a specific shape in this way, the structure constructed by stacking the auxiliary members 1 creates a geometric pattern (Figure 2), giving the building façade and pilotis a new aesthetic feel through the earthquake-resistant auxiliary structure.
