1 is a front view showing a seismic reinforcement structure using a steel plate according to an embodiment, FIG. 2 is a diagram showing a steel plate, FIG. 3 is a cross-sectional view of the seismic reinforcement structure shown in FIG. It is an enlarged view which shows a joining state.

本実施の形態による建築物の耐震補強構造は、図１に示すように、建築物などにおいて、柱２０と梁２１とに囲まれた開口部Ｒに鋼板補強部材１を設けたものである。   As shown in FIG. 1, the seismic reinforcement structure for a building according to the present embodiment has a steel plate reinforcing member 1 provided in an opening R surrounded by columns 20 and beams 21 in a building or the like.

図１に示すように、鋼板補強部材１は、角に切り欠きを有する略正方形状をなしていて同一の大きさに形成された鋼板２（図２参照）と、溝側を外方に向けて背中合わせとなるように鋼板２を両側から挟み込んだ状態で互いに交差して配置される溝形鋼からなる補強リブ３（補強部材）と、鋼板２および補強リブ３を一体に連結する接合ボルト４とから構成されている。
図２に示すように、鋼板２の外周部２ａには、接合ボルト４によって補強リブ３に接合できるようにボルト孔２ｂが形成されている。また、図４に示すように、補強リブ３の溝の底面には、鋼板２のボルト孔２ｂと一致する箇所にボルト孔３ａが形成されている。 As shown in FIG. 1, the steel plate reinforcing member 1 includes a steel plate 2 (see FIG. 2) having a substantially square shape with notches at the corners and formed in the same size, and a groove side facing outward. Reinforcing ribs 3 (reinforcing members) made of grooved steel that are arranged to cross each other with the steel plate 2 sandwiched from both sides so as to be back to back, and a joining bolt 4 that integrally connects the steel plate 2 and the reinforcing rib 3 It consists of and.
As shown in FIG. 2, a bolt hole 2 b is formed in the outer peripheral portion 2 a of the steel plate 2 so that it can be joined to the reinforcing rib 3 by the joining bolt 4. Further, as shown in FIG. 4, bolt holes 3 a are formed on the bottom surfaces of the grooves of the reinforcing ribs 3 at locations corresponding to the bolt holes 2 b of the steel plate 2.

複数の鋼板２は、開口部Ｒの同一面上で縦横を揃えるようにして並べて配置される。なお、図１に示すように、交差する補強リブ３で仕切られた複数の窓部１０において、鋼板２が配設される領域を鋼板補強領域１０ａ、鋼板２が設置されずに開口が形成される領域を開口領域１０ｂとする。そして、本実施の形態では、鋼板補強領域１０ａと開口領域１０ｂとは、図１に示す上下左右に互い違いとなるように、例えばチェス盤状又は市松模様状に配設されている。したがって、鋼板２同士の接合は、斜め方向に連結されることになる。   The plurality of steel plates 2 are arranged side by side so as to be aligned vertically and horizontally on the same surface of the opening R. As shown in FIG. 1, in the plurality of windows 10 partitioned by the reinforcing ribs 3 that intersect, the steel plate 2 is disposed in the region where the steel plate 2 is disposed, and an opening is formed without the steel plate 2 being installed. The area to be opened is referred to as an opening area 10b. And in this Embodiment, the steel plate reinforcement area | region 10a and the opening area | region 10b are arrange | positioned, for example in the shape of a chessboard or a checkered pattern so that it may become alternate up and down and right and left shown in FIG. Therefore, the joining between the steel plates 2 is connected in an oblique direction.

図２に示すように、各鋼板２の四辺の外周部２ａには、補強リブ３が重なるように配置される。ここで、このときの補強リブ３、３の間隔を所定間隔Ｄとする。
図１に示すように、鋼板２を両側から挟み込む補強リブ３は、一方側が縦方向に所定間隔Ｄで平行に配列される縦補強リブ３Ａ（第１補強部材）からなり、他方側が縦補強リブ３Ａに直交する横方向に所定間隔Ｄで平行に配列される横補強リブ３Ｂ（第２補強部材）からなる格子形状を構成している（図４参照）。 As shown in FIG. 2, the reinforcing ribs 3 are arranged so as to overlap the outer peripheral portions 2 a of the four sides of each steel plate 2. Here, the interval between the reinforcing ribs 3 and 3 is defined as a predetermined interval D.
As shown in FIG. 1, the reinforcing rib 3 that sandwiches the steel plate 2 from both sides is composed of vertical reinforcing ribs 3A (first reinforcing members) arranged in parallel at a predetermined interval D in the vertical direction and the other side is the vertical reinforcing rib. A lattice shape composed of lateral reinforcing ribs 3B (second reinforcing members) arranged in parallel at a predetermined interval D in the lateral direction orthogonal to 3A is formed (see FIG. 4).

図２に示すように、鋼板２の外周部２ａの図中左右が縦補強リブ３Ａに接合され、外周部２ａの図中上下が横補強リブ３Ｂに接合される。そして、縦補強リブ３Ａと横補強リブ３Ｂとが交差する箇所を交差接合部Ｓとしたときに、斜め方向に連結される鋼板部材２同士の連結部は、交差接合部Ｓで夫々の斜辺２ｃがつき合わせられて接合されている。
図４に示すように、これらの接合方法は、補強リブ３のボルト孔３ａと鋼板２のボルト孔２ｂとを一致させて接合ボルト４を挿通し、ナット５を螺合させる。このように、鋼板２の外周部２ａ全体に補強リブ３が固着されているため、鋼板２同士が強固に一体化された構造とすることができる。
なお、補強リブ３は、所定の長さに分割させておいてもよく、これにより施工時に取り扱いやすくなり、効率よく組立作業を行うことができる。 As shown in FIG. 2, the left and right sides of the outer peripheral portion 2a of the steel plate 2 are joined to the vertical reinforcing rib 3A, and the upper and lower sides of the outer peripheral portion 2a are joined to the horizontal reinforcing rib 3B. And when the location where the vertical reinforcing rib 3A and the horizontal reinforcing rib 3B intersect is defined as the cross-joining portion S, the connecting portions of the steel plate members 2 connected in the oblique direction are the respective oblique sides 2c at the cross-connecting portion S. Are joined together.
As shown in FIG. 4, in these joining methods, the bolt holes 3 a of the reinforcing rib 3 and the bolt holes 2 b of the steel plate 2 are matched, the joining bolt 4 is inserted, and the nut 5 is screwed. Thus, since the reinforcement rib 3 is being fixed to the whole outer peripheral part 2a of the steel plate 2, it can be set as the structure where the steel plates 2 were integrated firmly.
The reinforcing rib 3 may be divided into a predetermined length, which makes it easier to handle during construction and allows efficient assembly work.

次に、上述した構成からなる鋼板補強部材１を、建築物の柱２０と梁２１に接合する方法について説明する。
図１に示すように、開口部Ｒの内側には、四角形に枠組みされたＨ型鋼からなる枠部材２２が設けられている。この枠部材２２と柱２０、梁２１とは、柱２０や梁２１から内方に突設させたアンカー筋２３と、枠部材２２の外方に突設されたスタッドボルト２４とが重ね合わされ、その周囲にモルタルなどの充填材２５が充填されて固定されている。
そして、複数の鋼板２が一体化された鋼板補強部材１が、枠部材２２の内側に組み込まれ、鋼板補強部材１の外周に位置する鋼板２がボルト又は溶接などの固定手段によって枠部材２２に固着されている。これにより、鋼板補強部材１は本建築物の柱梁に一体に連結されることになる。 Next, a method of joining the steel plate reinforcing member 1 having the above-described configuration to the building pillar 20 and the beam 21 will be described.
As shown in FIG. 1, a frame member 22 made of H-shaped steel framed in a quadrangular shape is provided inside the opening R. The frame member 22, the column 20, and the beam 21 are overlapped with an anchor bar 23 projecting inward from the column 20 or beam 21 and a stud bolt 24 projecting outward from the frame member 22. A filler 25 such as mortar is filled and fixed around the periphery.
And the steel plate reinforcement member 1 with which the several steel plate 2 was integrated is integrated inside the frame member 22, and the steel plate 2 located in the outer periphery of the steel plate reinforcement member 1 is attached to the frame member 22 by fixing means, such as a volt | bolt or welding. It is fixed. Thereby, the steel plate reinforcement member 1 will be integrally connected to the column beam of this building.

上述した本実施の形態による建築物の耐震補強構造では、補強リブ３は、複数の鋼板２同士を繋ぎ合わせて一体化させるとともに、鋼板２を補強して従来と同等の耐震補強機能をもたせることができる。
また、鋼板２を設けないことで開口領域１０ｂを形成できることから、施工された鋼板耐震壁全面が遮へいされることなく、採光、眺望、通風などを確保することもできる。
本実施の形態による建築物の耐震補強構造では、溶接が不要な簡易な構造であり、接合ボルト４によって、格子状に配列された補強リブ３間の各空間一つおきに市松模様状に鋼板２を固着して連結できる。このため、開口部Ｒ内における耐震補強部材１の組み立てがボルト接合だけの簡略化された作業となり、これらの施工時間を減少できることから、施工性を向上させることができる。
また、本耐震補強構造では、補強リブ３の配列数や長さを変更することによって、補強する建築物の開口部Ｒの大きさに合わせた耐震補強部材１を施工できる。したがって、建築物の既存躯体における階高や柱梁間の寸法に対する適合性を向上させることができる。 In the seismic reinforcement structure for a building according to the above-described embodiment, the reinforcing rib 3 connects and integrates a plurality of steel plates 2 and reinforces the steel plates 2 to have a seismic reinforcement function equivalent to the conventional one. Can do.
Moreover, since the opening area | region 10b can be formed by not providing the steel plate 2, lighting, a view, a ventilation, etc. can also be ensured, without the constructed steel plate earthquake-proof wall whole surface being shielded.
The seismic reinforcement structure for buildings according to the present embodiment is a simple structure that does not require welding, and steel plates in a checkered pattern every other space between the reinforcing ribs 3 arranged in a lattice pattern by the joining bolts 4. 2 can be fixedly connected. For this reason, the assembly of the seismic reinforcement member 1 in the opening R is a simplified operation of only bolt joining, and the construction time can be reduced, so that the workability can be improved.
Moreover, in this earthquake-proof reinforcement structure, the earthquake-resistant reinforcement member 1 matched with the magnitude | size of the opening part R of the building to reinforce can be constructed by changing the arrangement number and length of the reinforcement rib 3. Therefore, the adaptability with respect to the floor height and the dimension between column beams in the existing frame of the building can be improved.

以上、本発明による建築物の耐震補強構造の実施の形態について説明したが、本発明は上記の実施形態に限定されるものではなく、その趣旨を逸脱しない範囲で適宜変更可能である。
例えば、本実施の形態では補強リブ３に溝形鋼を使用しているが、必ずしも溝形鋼に限定されることはない。要は鋼板２同士を接合ボルト４によって接合し、且つ連結された鋼板２を補強できればよいのであって、例えばＬ型鋼やＨ型鋼であってもかまわない。
本実施の形態では開口部Ｒ内の鋼板２の配置が、チェス盤状や市松模様状となるように開口領域１０ｂを設けるようにした配置であるが、この開口領域１０ｂの位置は任意であるとともに、開口領域１０ｂの必要性が無い場合には、開口部Ｒの全面に鋼板２を配置して鋼板補強領域１０ａとしてもよい。
また、鋼板２の形状を略正方形としているが、この形状に限定されることはない。例えば、上下左右の方向に隣り合うように鋼板２を並べて配設する際には、隣り合う両鋼板２、２が嵌合して接合できるようにその外周部２ａに凹凸を形成してもよい。
本実施の形態では柱梁と耐震補強部材１との接合で、開口部Ｒに枠部材２２を設けた例を示しているが、これに限定されず、例えば柱２０や梁２１に鋼板２を直接ボルト止め等で接続させて固定しても構わない。なお、本実施の形態では開口部Ｒに設けられている枠部材２２と柱梁との取り付け方法を、アンカー筋２３やスタッドボルト２４によるものとしているが、例えば接着などの他の方法によって取り付けもよい。
また、本実施の形態では鋼板２に補強リブ３が溶接されていないことから、補強する開口部Ｒの大きさに合わせて鋼板２を加工してもよく、寸法などを微調整してもかまわない。
さらにまた、本実施の形態では鋼板２は同一の大きさとしているが、１種類の大きさであることに限定されることはなく、複数の大きさの鋼板２を組み合わせてもよい。例えば、本実施の形態にある鋼板２に加えて、この鋼板２が二つ組み合わされた大きさの鋼板を設けても構わない。 As mentioned above, although embodiment of the earthquake-proof reinforcement structure of the building by this invention was described, this invention is not limited to said embodiment, In the range which does not deviate from the meaning, it can change suitably.
For example, in the present embodiment, a grooved steel is used for the reinforcing rib 3, but it is not necessarily limited to the grooved steel. The point is that the steel plates 2 may be joined together by the joining bolts 4 and the connected steel plates 2 may be reinforced, and for example, L-shaped steel or H-shaped steel may be used.
In the present embodiment, the arrangement of the steel plates 2 in the opening R is an arrangement in which the opening region 10b is provided so as to have a chessboard shape or a checkered pattern shape, but the position of the opening region 10b is arbitrary. At the same time, when there is no need for the opening region 10b, the steel plate 2 may be disposed on the entire surface of the opening R to form the steel plate reinforcing region 10a.
Moreover, although the shape of the steel plate 2 is made into a substantially square shape, it is not limited to this shape. For example, when the steel plates 2 are arranged side by side so as to be adjacent to each other in the vertical and horizontal directions, irregularities may be formed in the outer peripheral portion 2a so that the adjacent steel plates 2 and 2 can be fitted and joined. .
In the present embodiment, an example in which the frame member 22 is provided in the opening R by joining the column beam and the seismic reinforcement member 1 is shown. However, the present invention is not limited to this. For example, the steel plate 2 is attached to the column 20 or the beam 21. It may be fixed by directly connecting with bolts or the like. In this embodiment, the attachment method of the frame member 22 and the column beam provided in the opening R is made by the anchor bar 23 and the stud bolt 24. However, the attachment may also be made by other methods such as adhesion. Good.
Further, in the present embodiment, since the reinforcing rib 3 is not welded to the steel plate 2, the steel plate 2 may be processed according to the size of the opening R to be reinforced, or the dimensions may be finely adjusted. Absent.
Furthermore, in this Embodiment, although the steel plate 2 is made into the same magnitude | size, it is not limited to being one kind of magnitude | size, You may combine the steel plate 2 of a some magnitude | size. For example, in addition to the steel plate 2 in the present embodiment, a steel plate having a size in which two steel plates 2 are combined may be provided.
