Description

本発明は、耐震補強フレームに関する。   The present invention relates to a seismic reinforcement frame.
既存構造物には、外周柱の外側まで設けられたスラブの先端に外壁が構築され、外周柱の外側に設けられたスラブが既存構造物の内部スラブを形成する構成がある。このような既存構造物の耐震補強においては、外周柱の外側に設けられたスラブの活用を極力損なわず、かつ、十分な補強強度を備えた耐震補強フレームが求められている。
外周柱の外側に設けられたスラブを備えた既存構造物の耐震補強に関する技術には、例えば特許文献1がある。
The existing structure has a configuration in which an outer wall is constructed at the tip of the slab provided to the outside of the outer peripheral column, and the slab provided on the outer side of the outer peripheral column forms the inner slab of the existing structure. In the seismic reinforcement of such an existing structure, there is a demand for a seismic reinforcement frame that does not impair the use of the slab provided outside the outer peripheral column as much as possible and has sufficient reinforcement strength.
For example, Patent Document 1 discloses a technique related to seismic reinforcement of an existing structure including a slab provided outside the outer peripheral column.
特許文献1は、L字状及びI字状に形成した補強ピースで、外周柱の外側まで設けられたスラブ(外床部)を有する既存構造物を補強する構成である。ここに、補強ピースは、既存構造物の、外周柱の外側に設けられたスラブの上で、外周柱の外側の側面及び梁の外側の側面に沿ってL字状及びI字状に組み合わせられ、補強ピースが組み合わされた補強ユニットで既存構造物の外周柱と梁で形成される柱梁架構を補強する。ここに、補強ユニットは、門型形状や矩形形状に組み合わされて、既存構造物の柱梁架構の外周柱と上側の梁に取り付けられる。   Patent document 1 is a reinforcement piece formed in L shape and I shape, and is a structure which reinforces the existing structure which has the slab (outer floor part) provided to the outer side of the outer periphery pillar. Here, the reinforcing piece is combined in an L shape and an I shape along the outer side surface of the outer peripheral column and the outer side surface of the beam on the slab provided outside the outer peripheral column of the existing structure. The reinforcement unit in which the reinforcement pieces are combined reinforces the column beam frame formed by the outer peripheral columns and beams of the existing structure. Here, the reinforcing unit is combined with the gate shape or the rectangular shape, and is attached to the outer peripheral column and the upper beam of the column beam frame of the existing structure.

図1(A)、図2に示すように、耐震補強フレーム10は、既存構造物30を耐震補強する補強フレームであり、既存構造物30の一対の外周柱12R、12Lと、外周柱12R、12Lに架設された上下の梁14U、14Dで形成された、矩形状の柱梁架構44に取付けられている。   As shown in FIG. 1 (A) and FIG. 2, the seismic reinforcement frame 10 is a reinforcement frame that seismically reinforces the existing structure 30, and includes a pair of outer peripheral columns 12 </ b> R and 12 </ b> L, an outer peripheral column 12 </ b> R, It is attached to a rectangular column beam frame 44 formed by upper and lower beams 14U and 14D installed on 12L.
既存構造物30の梁14U、14Dは、上下のスラブ16U、16Dをそれぞれ支持している。スラブ16U、16Dの一部は、外周柱12R、12Lの外側まで設けられ、スラブ16U、16Dの先端部には、既存構造物30の外壁64が形成されている。外壁64には、窓66が設けられている。即ち、スラブ16U、16Dの外周柱12R、12Lの外側まで設けられた部分は、室内側のスラブを構成している。
なお、外周柱12R、12Lの外側まで設けられたスラブ16U、16Dは、跳ね出しスラブ構造であっても良いし、跳ね出し大梁、小梁で支持されたスラブ構造であってもよい。
The beams 14U and 14D of the existing structure 30 support the upper and lower slabs 16U and 16D, respectively. A part of the slabs 16U and 16D is provided to the outside of the outer peripheral pillars 12R and 12L, and an outer wall 64 of the existing structure 30 is formed at the front ends of the slabs 16U and 16D.

In other words, the portions of the slabs 16U and 16D that are provided to the outside of the outer peripheral pillars 12R and 12L constitute an indoor slab.
The slabs 16U and 16D provided to the outer sides of the outer peripheral columns 12R and 12L may have a protruding slab structure, or may have a slab structure supported by protruding large beams and small beams.
外周柱12R、12Lは、断面形状が矩形の鉄骨鉄筋コンクリート柱(SRC柱)で形成され、梁14R、14Dは、いずれもH形鋼で形成されている。スラブ16U、16Dは、鉄筋コンクリートで形成されている。   The outer peripheral columns 12R and 12L are formed of steel reinforced concrete columns (SRC columns) having a rectangular cross-sectional shape, and the beams 14R and 14D are each formed of H-shaped steel. Slabs 16U and 16D are formed of reinforced concrete.
耐震補強フレーム10は、一対の縦枠材(縦部材)18R、18Lを有している。縦枠材18R、18Lは、いずれもH形鋼で形成され、外周柱12R、12Lの外側の側面に接合されている。縦枠材18R、18Lの上端部はスラブ16Uの下面に達し、下端部は、スラブ16Dに設けられた開口部22を通過して、スラブ16Dの下まで達している。   The earthquake-proof reinforcement frame 10 has a pair of vertical frame members (vertical members) 18R and 18L. The vertical frame members 18R and 18L are all formed of H-shaped steel, and are joined to the outer side surfaces of the outer peripheral columns 12R and 12L. The upper ends of the vertical frame members 18R and 18L reach the lower surface of the slab 16U, and the lower ends pass through the opening 22 provided in the slab 16D and reach the bottom of the slab 16D.
図1(B)に示すように、外周柱12R、12Lと縦枠材18R、18Lは、アンカーボルト76で接合されている。また、縦枠材18R、18Lのウェブにはスタッド84が取付けられており、外周柱12R、12Lと縦枠材18R、18Lの間の空間にはモルタル78が充填されている。これにより、外周柱12R、12Lと縦枠材18R、18Lが強く接合され、一体化が図られている。   As shown in FIG. 1B, the outer peripheral columns 12R, 12L and the vertical frame members 18R, 18L are joined by anchor bolts 76. Further, studs 84 are attached to the webs of the vertical frame members 18R and 18L, and mortar 78 is filled in the space between the outer peripheral columns 12R and 12L and the vertical frame members 18R and 18L. As a result, the outer peripheral columns 12R and 12L and the vertical frame members 18R and 18L are strongly joined to achieve integration.
また、耐震補強フレーム10は、横部材(下側横枠材20Dと上側横枠材20U)を有している。下側横枠材(下側横部材)20Dは、スラブ16Dの下に配置され、両端部が縦枠材18R、18Lの下端部と接合されている。即ち、縦枠材18R、18Lは、スラブ16Dを切り欠いた開口部22を貫通して、下端部がスラブ16Dの下部に達しており、スラブ16Dの下部で、下側横枠材20Dの両端が、縦枠材18R、18Lの下端と接合される。また、下側横枠材20Dは、梁14Dの側面から張り出した連結部(連結部材)24Dに側面が接合されている。   Moreover, the earthquake-proof reinforcement frame 10 has a horizontal member (lower side frame material 20D and upper side frame material 20U). The lower horizontal frame member (lower horizontal member) 20D is disposed below the slab 16D, and both ends thereof are joined to the lower ends of the vertical frame members 18R and 18L. That is, the vertical frame members 18R and 18L pass through the opening 22 in which the slab 16D is cut out, and the lower end portion reaches the lower part of the slab 16D, and both ends of the lower horizontal frame member 20D at the lower part of the slab 16D. Are joined to the lower ends of the vertical frame members 18R, 18L. Further, the side surface of the lower horizontal frame member 20D is joined to a connecting portion (connecting member) 24D protruding from the side surface of the beam 14D.
耐震補強フレーム10は、上側横枠材(上側横部材)20Uを有している。上側横枠材20Uは、スラブ16Uの下に配置され、両端部が縦枠材18R、18Lの上端部と接合されている。更に、上側横枠材20Uは、上側の梁14Uの側面から張り出した連結部24Uに側面が接合されている。   The seismic reinforcement frame 10 has an upper lateral frame member (upper lateral member) 20U. The upper horizontal frame member 20U is disposed below the slab 16U, and both ends thereof are joined to the upper ends of the vertical frame members 18R and 18L. Furthermore, the side surface of the upper horizontal frame member 20U is joined to the connecting portion 24U protruding from the side surface of the upper beam 14U.
上側横枠材20Uと上側の梁14Uを接合する連結部(連結部材)24Uは、梁14Uのウェブから横に上側横枠材20Uへ向けて取付けられたスタッド86と、上側横枠材20Uのウェブから横に梁14Uへ向けて取付けられたスタッド88を有している。また、スタッド86、88の周囲には、鉄筋90が取付けられている。梁14Uと上側横枠材20Uの間には、スタッド86、88と鉄筋90の回りにモルタル92が打設されている。これにより、梁14Uと上側横枠材20Uが、強く接合される。
連結部(連結部材)24Dも、連結部24Uと同じ構成であり説明は省略する。
A connecting portion (connecting member) 24U that joins the upper lateral frame member 20U and the upper beam 14U is formed by connecting a stud 86 attached laterally from the web of the beam 14U toward the upper lateral frame member 20U, and the upper lateral frame member 20U. It has a stud 88 attached laterally from the web toward the beam 14U. Reinforcing bars 90 are attached around the studs 86 and 88. A mortar 92 is placed around the studs 86 and 88 and the reinforcing bar 90 between the beam 14U and the upper horizontal frame member 20U. Thereby, the beam 14U and the upper side frame member 20U are strongly joined.
The connecting portion (connecting member) 24D has the same configuration as the connecting portion 24U, and a description thereof will be omitted.
また、耐震補強フレーム10は、縦枠材18R、18Lと上側横部材20U、下側横部材20Dで枠体32を構成している。枠体32は矩形状に形成され、枠体32の内部には、一対のブレース(枠体補強部材)26R、26Lが設けられている。
ブレース26R、26Lは、H形鋼で形成され、下端部が下側横枠材20Dの中央部に固定された板材28に固定されている。また、上端部が縦枠材18R、18Lと、上側横枠材20Uの接合部(角部)に固定されている。即ち、ブレース26R、26Lは、中央部が低く両端部が高い下に凸の形状に配置されている。
Moreover, the seismic reinforcement frame 10 comprises the frame 32 by the vertical frame members 18R and 18L, the upper horizontal member 20U, and the lower horizontal member 20D. The frame body 32 is formed in a rectangular shape, and a pair of braces (frame body reinforcing members) 26 </ b> R and 26 </ b> L are provided inside the frame body 32.
The braces 26R and 26L are formed of H-shaped steel, and a lower end portion is fixed to a plate member 28 fixed to a central portion of the lower lateral frame member 20D. Moreover, the upper end part is being fixed to the junction part (corner | corner part) of the vertical frame materials 18R and 18L and the upper side horizontal frame material 20U. That is, the braces 26R and 26L are arranged in a convex shape with a lower central portion and higher end portions.
これにより、枠体32が水平力を受けたとき、ブレース26R、26Lにより、枠体32の変形が抑制される。上述したように、枠体32の側面は、既存構造物30の柱梁架構44の側面と、全周囲に渡り全ての部材が接合されているので、柱梁架構44の変形を抑制することができる。更に、柱梁架構44の耐力を向上させることができる。
この結果、耐震補強フレーム10により、既存構造物30の構造部材である外周柱12R、12L、及び梁14U、14Lを補強することができる。更に、本実施形態によれば、枠体32が、外周柱12R、12Lの外側に固定され、下側横枠材20Dがスラブ16Dの下に設けられるので、室内空間を広く確保できる。
Thereby, when the frame body 32 receives horizontal force, the braces 26R and 26L suppress the deformation of the frame body 32. As described above, since all the members of the side surface of the frame body 32 are joined to the side surface of the column beam frame 44 of the existing structure 30 and the entire periphery, the deformation of the column beam frame 44 can be suppressed. it can. Furthermore, the proof stress of the column beam frame 44 can be improved.
As a result, the outer peripheral columns 12R and 12L and the beams 14U and 14L, which are structural members of the existing structure 30, can be reinforced by the seismic reinforcement frame 10. Furthermore, according to the present embodiment, the frame 32 is fixed to the outer sides of the outer peripheral columns 12R and 12L, and the lower horizontal frame member 20D is provided under the slab 16D, so that a wide indoor space can be secured.
なお、本実施形態では、外周柱12R、12Lが鉄骨鉄筋コンクリート柱(SRC柱)の場合について説明した。しかし、これに限定されることはなく、例えば鉄筋コンクリート柱(RC柱)や鉄骨柱(S柱)等、構造種別を問わず一般的な柱の全てに適用できる。   In the present embodiment, the case where the outer peripheral columns 12R and 12L are steel reinforced concrete columns (SRC columns) has been described. However, the present invention is not limited to this, and can be applied to all general columns such as reinforced concrete columns (RC columns) and steel columns (S columns) regardless of the structural type.
次に、本実施形態に係る補強部材の展開例について説明する。
図3(A)に第1展開例を示す。第1展開例のブレース(補強部材)34R、34Lは、枠体32に対する取付け方向を、図1で説明したブレース26R、26Lと上下を逆にした構成である。即ち、ブレース34R、34Lを、中央部が上側横枠材20Uの中央部に固定された板材28に固定されている。また、下端部が縦枠材18R、18Lと、下側横枠材20Dの接合部(角部)に固定されている。即ち、中央部が高く両端部が低い、上に凸の形状に配置している。
この構成においても、ブレース26R、26Lと同じ効果を得ることができる。なお、ブレース34R、34Lは、要求される横荷重が小さい場合には、角部にのみ設けてもよい。
Next, a development example of the reinforcing member according to the present embodiment will be described.
FIG. 3A shows a first development example. The braces (reinforcing members) 34R and 34L of the first development example have a configuration in which the mounting direction with respect to the frame body 32 is upside down with respect to the braces 26R and 26L described in FIG. In other words, the braces 34R and 34L are fixed to the plate member 28 whose central portion is fixed to the central portion of the upper lateral frame member 20U. Moreover, the lower end part is being fixed to the junction part (corner | corner part) of vertical frame material 18R, 18L and lower side horizontal frame material 20D. That is, it is arranged in an upwardly convex shape with a high center and low ends.
Even in this configuration, the same effects as the braces 26R and 26L can be obtained. The braces 34R and 34L may be provided only at the corners when the required lateral load is small.
図3(B)に第2展開例を示す。第2展開例の補強部材36R、36Lは、枠体32に対する取付け方向を斜めでなく縦方向としている。これにより、補強部材36R、36Lの視覚に訴える安定感を増すことができる。
但し、この場合には、横荷重に対する枠体32の剛性を確保するため、補強部材36R、36Lの幅寸法は、ブレース26R、26Lより大きくする必要がある。
FIG. 3B shows a second development example. In the reinforcing members 36R and 36L of the second development example, the mounting direction with respect to the frame body 32 is not diagonal but is the vertical direction. Thereby, the sense of stability appealing to the vision of the reinforcing members 36R and 36L can be increased.
However, in this case, in order to ensure the rigidity of the frame body 32 with respect to the lateral load, the width dimensions of the reinforcing members 36R and 36L need to be larger than those of the braces 26R and 26L.

The lower horizontal frame member 42D has both ends joined to the lower portions of the vertical frame members 46R and 46L, and the side surfaces are connected to the connecting member 62 on the slab 16D.
連結部材62は、下側の梁14Dと下側横枠材42Dを連結するための鋼材製の部材である。スラブ16Dの下側の梁14Dの上方には、梁14Dのフランジ幅より大きい開口部58が設けられている。
連結部材62は、H形鋼製の立上げ部材52を有し、立上げ部材52が、下側の梁14Dの上から開口部58を通り立ち上げられている。
The connecting member 62 is a steel member for connecting the lower beam 14D and the lower lateral frame member 42D. An opening 58 larger than the flange width of the beam 14D is provided above the beam 14D on the lower side of the slab 16D.
The connecting member 62 has a rising member 52 made of H-shaped steel, and the rising member 52 is raised from above the lower beam 14D through the opening 58.
立上げ部材52は、梁14Dの上フランジに下フランジを接合して立ち上げられている。立上げ部材52のスラブ16Dからの立上げ高さは、下側横枠材42Dの高さにほぼ等しくされている。立上げ部材52の上フランジには、連結板54Uの一端が接合され、連結板54Uの他端は、下側横枠材42Dの上フランジと接合されている。   The rising member 52 is raised by joining the lower flange to the upper flange of the beam 14D. The rising height of the rising member 52 from the slab 16D is substantially equal to the height of the lower horizontal frame member 42D. One end of the connecting plate 54U is joined to the upper flange of the rising member 52, and the other end of the connecting plate 54U is joined to the upper flange of the lower horizontal frame member 42D.

(Third embodiment)
A seismic reinforcement frame 60 according to the third embodiment will be described with reference to FIGS. 6 and 7.
6 is a front view showing a state in which the seismic reinforcement frame 60 is attached, and FIG. 7 is a cross-sectional view taken along line X1-X1 of FIG.
The seismic reinforcing frame 60 is different from the seismic reinforcing frame 10 according to the first embodiment in that a frame 72 constituted by a vertical member 68 and a horizontal member 70 is arranged inside the column beam frame 44. The difference will be mainly described.
図6、図7に示すように、耐震補強フレーム60は、外周柱12R、12Lに接合される縦枠材68R、68L、縦枠材68R、68Lの下端部に接合される下側横枠材70Dと、上端部に接合される上側横枠材70Uを有している。
縦枠材68R、68L、下側横枠材70D、及び上側横枠材70Uで、枠体72が形成される。枠体72は、内部に設けられたブレース74R、74Lで補強されている。
As shown in FIGS. 6 and 7, the seismic reinforcement frame 60 is composed of vertical frame members 68R and 68L bonded to the outer peripheral columns 12R and 12L, and lower horizontal frame members bonded to the lower ends of the vertical frame members 68R and 68L. 70D and an upper horizontal frame member 70U joined to the upper end.
A frame body 72 is formed by the vertical frame members 68R and 68L, the lower horizontal frame member 70D, and the upper horizontal frame member 70U. The frame 72 is reinforced with braces 74R and 74L provided inside.
縦枠材68R、68Lは、下側の梁14Dの上面と、上側の梁14Uの下面の間に設けられ、外周柱12R、12Lの対向する側面に接合されている。また、上側横枠材70Uは、両端部が縦枠材68R、68Lの上部と接合され、上側の梁14Uの下フランジに上フランジの上面が接合されている。 The vertical frame members 68R and 68L are provided between the upper surface of the lower beam 14D and the lower surface of the upper beam 14U, and are joined to the opposite side surfaces of the outer peripheral columns 12R and 12L. Further, both ends of the upper horizontal frame member 70U are joined to the upper portions of the vertical frame members 68R and 68L, and the upper surface of the upper flange is joined to the lower flange of the upper beam 14U.
下側横枠材70Dは、両端部が縦枠材68R、68Lの下部と接合され、スラブ16Dを切り欠いた開口部94に配置され、下側横枠材70Dの下フランジを、下側の梁14Dの上フランジの上に連結させている。これにより、下側横枠材70Dと梁14Dが接合される。この結果、既存構造物30の柱梁架構44の全周囲を、枠体72で補強することができる。この結果、柱梁架構44の変形を抑制することができると共に、柱梁架構44の耐力を向上させることができる。   The lower horizontal frame member 70D is disposed at the opening 94 where both ends are joined to the lower portions of the vertical frame members 68R and 68L, and the slab 16D is cut out. It is connected on the upper flange of the beam 14D. As a result, the lower horizontal frame member 70D and the beam 14D are joined. As a result, the entire periphery of the column beam frame 44 of the existing structure 30 can be reinforced by the frame body 72. As a result, deformation of the column beam frame 44 can be suppressed and the proof stress of the column beam frame 44 can be improved.
本実施形態によれば、下側横枠材70Dがスラブ16Dの上に設けられ、室内空間の一部が占められるが、下階空間へ影響を及ぼさず補強工事を行うことができる。また、既存躯体や設備機器との取り合いが少ない。

(第4実施形態)
図8を用いて、第3実施形態に係る耐震補強フレーム80について説明する。
耐震補強フレーム80は、縦枠材18R、18L、上側横部材20U、下側横部材20Dで構成された枠体82の内部に、補強部材が取り付けられていない点において、第1実施形態に係る耐震補強フレーム10と相違する。相違点を中心に説明する。
(Fourth embodiment)
The earthquake-proof reinforcement frame 80 which concerns on 3rd Embodiment is demonstrated using FIG.
The seismic reinforcement frame 80 is related to the first embodiment in that no reinforcement member is attached to the inside of the frame body 82 constituted by the vertical frame members 18R and 18L, the upper horizontal member 20U, and the lower horizontal member 20D. It differs from the seismic reinforcement frame 10. The difference will be mainly described.
耐震補強フレーム80は、一対の縦枠材18R、18Lを有し、外周柱12R、12Lの外側の側面に接合されている。縦枠材18R、18Lの上端部はスラブ16Uの下面に達し、下端部は、スラブ16Dに設けられた開口部22を通過して、スラブ16Dの下まで達している。
また、耐震補強フレーム80の下側横枠材20Dは、スラブ16Dの下に配置され、両端部が縦枠材18R、18Lの下端部と、スラブ16Dの下で接合されている。下側横枠材20Dの側面は、梁14Dの側面から張り出した連結部24Dで接合されている(図2参照)。
The seismic reinforcement frame 80 has a pair of vertical frame members 18R and 18L, and is joined to the outer side surfaces of the outer peripheral columns 12R and 12L. The upper ends of the vertical frame members 18R and 18L reach the lower surface of the slab 16U, and the lower ends pass through the opening 22 provided in the slab 16D and reach the bottom of the slab 16D.
The lower horizontal frame member 20D of the seismic reinforcement frame 80 is disposed below the slab 16D, and both ends are joined to the lower ends of the vertical frame members 18R and 18L under the slab 16D. The side surface of the lower horizontal frame member 20D is joined by a connecting portion 24D protruding from the side surface of the beam 14D (see FIG. 2).
また、上側横枠材20Uは、スラブ16Uの下に配置され、両端部が縦枠材18R、18Lの上端部と接合されている。上側横枠材20Uは、上側の梁14Uの側面から張り出した連結部24Uに側面が接合されている(図2参照)。   Further, the upper horizontal frame member 20U is disposed under the slab 16U, and both ends thereof are joined to the upper ends of the vertical frame members 18R and 18L. The side surface of the upper horizontal frame member 20U is joined to a connecting portion 24U protruding from the side surface of the upper beam 14U (see FIG. 2).
耐震補強フレーム80は、縦枠材18R、18Lと上側横部材20U、下側横部材20Dで矩形の枠体82を構成している。枠体82には、ブレース(補強部材)は設けられていない。枠体82は、補強部材が設けられていない分、横荷重に対する剛性は低下するが、大きな剛性を要求しない既存構造物30においては、既存構造物30の柱梁架構と全周囲が接合されているので、既存構造物30の変形を抑制することができる。更に、柱梁架構44の耐力を向上させることができる。   In the seismic reinforcement frame 80, the vertical frame members 18R and 18L, the upper horizontal member 20U, and the lower horizontal member 20D constitute a rectangular frame 82. The frame 82 is not provided with braces (reinforcing members). Since the frame member 82 is not provided with the reinforcing member, the rigidity against the lateral load is reduced. However, in the existing structure 30 that does not require a large rigidity, the column beam frame of the existing structure 30 and the entire periphery are joined. Therefore, the deformation of the existing structure 30 can be suppressed. Furthermore, the proof stress of the column beam frame 44 can be improved.
なお、本実施形態は、第1実施形態の枠体32に適用した場合を例にとり説明した。しかしこれに限定されることはなく、第2実施形態の枠体50、及び第3実施形態の枠体72に適用してもよい。他の構成は、第1実施形態と同じであり説明は省略する。   In addition, this embodiment demonstrated taking the case where it applied to the frame 32 of 1st Embodiment as an example. However, the present invention is not limited to this, and may be applied to the frame body 50 of the second embodiment and the frame body 72 of the third embodiment. Other configurations are the same as those of the first embodiment, and a description thereof will be omitted.
