Description
本発明は、組積橋脚などの組積造構造物を補強する補強構造に関する。 The present invention relates to a reinforcing structure for reinforcing a masonry structure such as a masonry pier.
従来、既設のコンクリート構造物を補強する手法として、コンクリート構造物の上端面からコンクリート構造物の基礎部に達する孔を形成し、その孔に鋼棒を挿入して設置した後、孔の内壁と鋼棒の間にモルタルを充填する補強方法が知られている（例えば、特許文献１参照。）。 Conventionally, as a method to reinforce an existing concrete structure, a hole reaching the foundation of the concrete structure is formed from the upper end surface of the concrete structure, a steel rod is inserted into the hole, and then the inner wall of the hole is connected. A reinforcing method for filling mortar between steel bars is known (for example, see Patent Document 1).
また、石積みやレンガ積みの組積造構造物である、既設の組積橋脚を補強する手法として、組積橋脚の周囲に鉄筋コンクリートや鋼板を巻き立てる巻き立て工法が知られている（例えば、非特許文献１参照。）。 In addition, as a method for reinforcing an existing masonry pier, which is a masonry structure of masonry or brick masonry, a winding method in which reinforced concrete or steel plate is wound around the masonry pier is known (for example, non (See Patent Document 1).
しかしながら、上記特許文献１のコンクリート構造物の補強方法を組積造構造物に適用した場合、例えば地震時に鋼棒が負担する水平荷重が組積造構造物に伝達されることで、組積造構造物に発生する応力が大きくなってしまい、組積造構造物が崩れ易くなるおそれがある。 However, when the method for reinforcing a concrete structure disclosed in Patent Document 1 is applied to a masonry structure, for example, a horizontal load borne by a steel bar during an earthquake is transmitted to the masonry structure. The stress generated in the structure may increase, and the masonry structure may easily collapse.
また、上記非特許文献１のような巻き立て工法によると、断面積が増加するといった補強対象の構造物の大型化を招くため、建築限界や河積阻害率などの空間的な制約がある箇所の組積造構造物には適用できないことがある。 In addition, according to the winding method as described in Non-Patent Document 1, since the structure to be reinforced is increased in size such as a cross-sectional area, there is a place where there is a spatial restriction such as a building limit or a river volume inhibition rate. May not be applicable to other masonry structures.
本発明の目的は、組積造構造物を補強するのに適した組積造構造物の補強構造を提供することである。 An object of the present invention is to provide a reinforcing structure for a masonry structure suitable for reinforcing the masonry structure.
上記目的を達成するため、この発明に係る組積造構造物の補強構造は、
組積造構造物を上下に貫通した貫通孔に配設されている補強部材を備え、
前記補強部材は、芯材と、その芯材の周面を覆った緩衝材とを有し、
前記緩衝材が前記貫通孔の孔壁に内接しているようにした。
In order to achieve the above object, the masonry structure reinforcing structure according to the present invention is:
Comprising a reinforcing member disposed in a through-hole penetrating the masonry structure vertically;
The reinforcing member has a core material and a cushioning material covering the peripheral surface of the core material,
The buffer material is inscribed in the hole wall of the through hole.
かかる構成の組積造構造物の補強構造においては、補強部材の緩衝材が貫通孔の孔壁に内接しているので、例えば、地震時に組積造構造物と補強部材との衝撃を弱めるとともに、補強部材が大きな水平荷重を負担したとしても、芯材と組積造構造物の間に介装されている緩衝材によって、組積造構造物に発生する応力を抑制することができる。
つまり、組積造構造物に形成された貫通孔内に、芯材の周面に緩衝材が設けられている補強部材が設置されている組積造構造物の補強構造であれば、地震時に組積造構造物に発生する応力を小さくすることができ、石積みやレンガ積みが崩れ難くなるので、組積造構造物が崩壊するのを低減することができる。
In the reinforcement structure of a masonry structure having such a configuration, since the cushioning material of the reinforcement member is inscribed in the hole wall of the through-hole, for example, the impact between the masonry structure and the reinforcement member is reduced during an earthquake. Even when the reinforcing member bears a large horizontal load, the stress generated in the masonry structure can be suppressed by the cushioning material interposed between the core material and the masonry structure.
In other words, if the reinforcement structure of a masonry structure in which a reinforcing member in which a buffer material is provided on the peripheral surface of the core material is installed in the through hole formed in the masonry structure, at the time of an earthquake Since the stress generated in the masonry structure can be reduced and the masonry or brickwork is less likely to collapse, it is possible to reduce the collapse of the masonry structure.
これに対し、鋼棒と組積造構造物の間にモルタルを充填し、組積造構造物と鋼棒をモルタルによって付着した場合、例えば、地震時に鋼棒が負担する水平荷重が組積造構造物に伝達されることで、大きな応力が組積造構造物に発生して、石積みやレンガ積みが崩れてしまうおそれがあるので、従来技術（特許文献１）の補強方法を組積造構造物に適用するには課題があった。
このように、本発明にかかる組積造構造物の補強構造は、石積みやレンガ積みなどの組積造構造物を補強するのに適した補強構造である。
On the other hand, when mortar is filled between a steel bar and a masonry structure and the masonry structure and the steel bar are attached by mortar, for example, the horizontal load borne by the steel bar during an earthquake is Since a large stress is generated in the masonry structure by being transmitted to the structure, there is a risk that the masonry or the brickwork may collapse. Therefore, the reinforcement method of the prior art (Patent Document 1) is applied to the masonry structure. There was a problem to apply to things.
Thus, the reinforcement structure of the masonry structure according to the present invention is a reinforcement structure suitable for reinforcing the masonry structure such as masonry or brick masonry.
また、望ましくは、
前記補強部材は、前記組積造構造物の下端から突出し、前記組積造構造物を支持している基礎構造体に貫入されているようにする。
こうすることで、基礎構造体に支持されている組積造構造物を好適に補強することができる。
Also, preferably

By doing so, the masonry structure supported by the foundation structure can be suitably reinforced.
また、望ましくは、
前記芯材は鋼管であるようにする。
こうすることで、組積造構造物に形成された貫通孔内に補強部材を設置し易くなる。
Also, preferably
The core material is a steel pipe.
By doing so, it becomes easier to install the reinforcing member in the through hole formed in the masonry structure.
また、望ましくは、
前記鋼管の内部には、充填材が充填されているようにする。
こうすることで、鋼管の内部に充填される充填材に応じて、補強部材の強度を調整することが可能になる。
Also, preferably
The steel pipe is filled with a filler.
By carrying out like this, it becomes possible to adjust the intensity | strength of a reinforcement member according to the filler with which the inside of a steel pipe is filled.
また、望ましくは、
前記鋼管の内部には、その鋼管よりも径の小さな小径鋼管が配設されており、
前記鋼管と前記小径鋼管の間には、粘性体が介在されているようにする。
粘性体を利用した補強部材が、組積造構造物の貫通孔内に設置されている組積造構造物の補強構造であれば、地震時に組積造構造物に発生する応力をより小さくすることができ、石積みやレンガ積みが崩れ難くなるので、組積造構造物が崩壊するのをより一層低減することができる。
Also, preferably
Inside the steel pipe, a small-diameter steel pipe having a smaller diameter than the steel pipe is disposed,
A viscous body is interposed between the steel pipe and the small diameter steel pipe.
If the reinforcing member using a viscous material is a reinforcing structure for a masonry structure installed in the through hole of the masonry structure, the stress generated in the masonry structure during an earthquake will be reduced Since masonry and brickwork are less likely to collapse, the masonry structure can be further prevented from collapsing.
本発明によれば、組積造構造物を補強するのに適した組積造構造物の補強構造が得られる。 ADVANTAGE OF THE INVENTION According to this invention, the reinforcement structure of a masonry structure suitable for reinforcing a masonry structure is obtained.
以下、図面を参照して、本発明に係る組積造構造物の補強構造の実施形態について詳細に説明する。但し、以下に述べる実施形態には、本発明を実施するために技術的に好ましい種々の限定が付されているが、本発明の範囲を以下の実施形態及び図示例に限定するものではない。 Hereinafter, an embodiment of a reinforcing structure for a masonry structure according to the present invention will be described in detail with reference to the drawings. However, the embodiments described below are given various technically preferable limitations for carrying out the present invention, but the scope of the present invention is not limited to the following embodiments and illustrated examples.
組積造構造物は、例えば、石、レンガ、コンクリートブロックなどを、モルタルなどの目地材で接着して積み上げて形成した構造物である。
このような組積造構造物を補強するのに適した補強構造について説明する。
The masonry structure is, for example, a structure formed by bonding and stacking stones, bricks, concrete blocks, and the like with joint materials such as mortar.
A reinforcing structure suitable for reinforcing such a masonry structure will be described.
本実施形態の組積造構造物の補強構造１００は、図１（ａ）（ｂ）に示すように、組積造構造物１を上下に貫通した貫通孔２に配設されている補強部材１０を備えて構成されている。
この補強部材１０は、組積造構造物１の下端から突出し、組積造構造物１を支持している基礎構造体３に貫入している。
A reinforcement structure 100 for a masonry structure according to the present embodiment includes a reinforcement member disposed in a through-hole 2 that vertically penetrates the masonry structure 1 as shown in FIGS. 10.
The reinforcing member 10 protrudes from the lower end of the masonry structure 1 and penetrates into the foundation structure 3 that supports the masonry structure 1.
補強部材１０は、貫通孔２に挿通された状態で配設されている長尺な部材であり、芯材としての鋼棒１１と、その鋼棒１１の周面を覆った緩衝材１２とを有している。 The reinforcing member 10 is a long member disposed in a state of being inserted through the through hole 2, and includes a steel rod 11 as a core material and a buffer material 12 covering the peripheral surface of the steel rod 11. Have.
鋼棒１１は、鋼製の棒状部材であり、本実施形態では断面が円形を呈する丸鋼を用いた。 The steel rod 11 is a steel rod-shaped member, and in this embodiment, a round steel having a circular cross section is used.
緩衝材１２は、例えば、天然ゴムや合成ゴムなどの弾性材料や発泡プラスチックなどの合成樹脂材料からなる部材や砂であり、衝撃を緩和する機能を有している。
この緩衝材１２は、鋼棒１１を被覆するように、例えば、帯状の弾性材料を鋼棒１１（芯材）の周面に巻き付けたり、管状の弾性材料を鋼棒１１（芯材）の周面に装着したりして取り付けられている。
そして、補強部材１０が貫通孔２内に設置された状態で、緩衝材１２が貫通孔２の孔壁に内接するようになっている。
なお、緩衝材１２は、一層構造であっても、二層以上重ねた構造を有していてもよい。
The buffer material 12 is, for example, a member or sand made of an elastic material such as natural rubber or synthetic rubber, or a synthetic resin material such as foamed plastic, and has a function of mitigating impact.
The buffer material 12 is formed by, for example, winding a belt-shaped elastic material around the circumferential surface of the steel rod 11 (core material) or covering a tubular elastic material around the steel rod 11 (core material) so as to cover the steel rod 11. It is attached to the surface.
The cushioning material 12 is inscribed in the hole wall of the through hole 2 in a state where the reinforcing member 10 is installed in the through hole 2.
The buffer material 12 may have a single-layer structure or a structure in which two or more layers are stacked.
次に、本実施形態の組積造構造物の補強構造１００を構築する手順について説明する。
例えば、補強対象の組積造構造物１は、図２（ａ）（ｂ）に示すように、地中に埋設された基礎構造体３に支持されている。
Next, a procedure for constructing the reinforcing structure 100 for a masonry structure according to this embodiment will be described.
For example, the masonry structure 1 to be reinforced is supported by a foundation structure 3 embedded in the ground, as shown in FIGS.
まずは、図３（ａ）（ｂ）に示すように、組積造構造物１を上下に貫通する貫通孔２を形成する。
また、組積造構造物１に貫通孔２を形成する際、その貫通孔２に連なる孔４を基礎構造体３に形成する。
First, as shown to Fig.3 (a) (b), the through-hole 2 which penetrates the masonry structure 1 up and down is formed.
Further, when the through hole 2 is formed in the masonry structure 1, the hole 4 connected to the through hole 2 is formed in the foundation structure 3.
そして、組積造構造物１の貫通孔２に補強部材１０を挿し入れるように設置することで、図１（ａ）（ｂ）に示すように、補強部材１０によって組積造構造物１を補強してなる組積造構造物の補強構造１００を構築することができる。
なお、補強部材１０の下端部は、基礎構造体３の孔４に貫入している。
And by installing so that the reinforcement member 10 may be inserted in the through-hole 2 of the masonry structure 1, the masonry structure 1 can be formed by the reinforcement member 10 as shown in FIGS. The reinforcement structure 100 of the masonry structure formed by reinforcement can be constructed.
Note that the lower end portion of the reinforcing member 10 penetrates into the hole 4 of the foundation structure 3.
さらに、図４（ａ）（ｂ）に示すように、組積造構造物の補強構造１００において、組積造構造物１の上面に露出している補強部材１０の上端部を覆うように、閉塞部２０を設けることが好ましい。
閉塞部２０は、例えば、貫通孔２の開口サイズよりも大きな支圧板２１と、支圧板２１を補強部材１０の上端部に固定するボルトなどの固定具２２と、支圧板２１及び固定具２２を覆う防水層２３と、防水層２３の上に固設されたコンクリート体２４等を備えている。
防水層２３は、例えば、防水シートを貼設したり、防水塗料を塗布したりして設けた不透水層である。この防水層２３の外縁が組積造構造物１の上面にかかるように設けられている。
また、コンクリート体２４には、そのひび割れを防止するために、籠状に配筋した鉄筋が埋め込まれている。
このような閉塞部２０を設けることで、鋼棒１１が腐食したり、貫通孔２の孔壁と補強部材１０の隙間に雨水が浸み込んだりするのを防ぐことができ、経年劣化を抑え、組積造構造物の補強構造１００の耐久性を向上させることが可能になる。
Further, as shown in FIGS. 4A and 4B, in the reinforcement structure 100 for a masonry structure, so as to cover the upper end portion of the reinforcement member 10 exposed on the upper surface of the masonry structure 1, It is preferable to provide the blocking part 20.
The closing part 20 includes, for example, a bearing plate 21 larger than the opening size of the through hole 2, a fixture 22 such as a bolt for fixing the bearing plate 21 to the upper end of the reinforcing member 10, and the bearing plate 21 and the fixture 22. A waterproof layer 23 to be covered and a concrete body 24 fixed on the waterproof layer 23 are provided.
The waterproof layer 23 is a water-impermeable layer provided by sticking a waterproof sheet or applying a waterproof paint, for example. The outer edge of the waterproof layer 23 is provided so as to cover the upper surface of the masonry structure 1.
In addition, in the concrete body 24, reinforcing bars arranged in a hook shape are embedded in order to prevent the cracks.
By providing such a blocking portion 20, it is possible to prevent the steel bar 11 from corroding and rain water from entering the gap between the hole wall of the through hole 2 and the reinforcing member 10, and suppress deterioration over time. The durability of the reinforcing structure 100 for a masonry structure can be improved.
このように、組積造構造物１に形成された貫通孔２内に補強部材１０が設置されてなる組積造構造物の補強構造１００においては、補強部材１０の緩衝材１２が貫通孔２の孔壁に内接しているので、例えば、地震時に補強部材１０が大きな水平荷重を負担したとしても、鋼棒１１と組積造構造物１の間に介装されている緩衝材１２によって、組積造構造物１と補強部材１０との衝撃を弱めるとともに、組積造構造物１に発生する応力を抑制することができる。
つまり、本実施形態の組積造構造物の補強構造１００であれば、地震時に組積造構造物１に発生する応力を小さくすることができ、石積みやレンガ積みが崩れ難くなるので、組積造構造物１が崩壊するのを低減することができる。
Thus, in the reinforcement structure 100 of a masonry structure in which the reinforcement member 10 is installed in the through hole 2 formed in the masonry structure 1, the cushioning material 12 of the reinforcement member 10 is the through hole 2. For example, even if the reinforcing member 10 bears a large horizontal load at the time of an earthquake, the buffer material 12 interposed between the steel bar 11 and the masonry structure 1 While the impact of the masonry structure 1 and the reinforcing member 10 can be weakened, the stress generated in the masonry structure 1 can be suppressed.
That is, if the reinforcement structure 100 of the masonry structure according to the present embodiment, the stress generated in the masonry structure 1 at the time of an earthquake can be reduced, and masonry or brick masonry is not easily collapsed. It is possible to reduce the collapse of the structure 1.
これに対し、鋼棒１１と組積造構造物１の間にモルタルを充填し、組積造構造物１と鋼棒１１をモルタルによって付着した場合、例えば、地震時に鋼棒１１が負担する水平荷重が組積造構造物に伝達されることで、大きな応力が組積造構造物１に発生して、石積みやレンガ積みが崩れてしまうおそれがあるので、従来技術（特許文献１）の補強方法を組積造構造物１に適用するには課題があった。 On the other hand, when the mortar is filled between the steel bar 11 and the masonry structure 1 and the masonry structure 1 and the steel bar 11 are attached by the mortar, for example, the horizontal that the steel bar 11 bears during an earthquake. Since the load is transmitted to the masonry structure, a large stress is generated in the masonry structure 1 and the masonry or the brickwork may collapse. There was a problem in applying the method to the masonry structure 1.
以上のように、本実施形態の組積造構造物の補強構造１００は、組積造構造物１を補強するのに適した補強構造である。 As described above, the masonry structure reinforcing structure 100 according to this embodiment is a reinforcement structure suitable for reinforcing the masonry structure 1.
なお、本発明は上記実施形態に限られるものではない。
例えば、図５（ａ）（ｂ）に示すように、補強部材１０は、芯材としての鋼管１３と、その鋼管１３の周面を覆った緩衝材１２とを有している長尺部材であってもよい。
そして、補強部材１０の芯材に用いた鋼管１３の内部には、モルタルやグラウトなどの充填材１４が充填されている。
このような補強部材１０が組積造構造物１の貫通孔２内に設置されている組積造構造物の補強構造１００であっても、地震時に組積造構造物１に発生する応力を小さくすることができ、石積みやレンガ積みが崩れ難くなるので、組積造構造物１が崩壊するのを低減することができる。
なお、図５（ａ）（ｂ）に示した組積造構造物の補強構造１００にも、閉塞部２０を設けることが好ましい。
The present invention is not limited to the above embodiment.
For example, as shown in FIGS. 5A and 5B, the reinforcing member 10 is a long member having a steel pipe 13 as a core material and a cushioning material 12 covering the peripheral surface of the steel pipe 13. There may be.
And the inside of the steel pipe 13 used for the core material of the reinforcing member 10 is filled with fillers 14 such as mortar and grout.
Even if such a reinforcing member 10 is a masonry structure reinforcing structure 100 installed in the through hole 2 of the masonry structure 1, the stress generated in the masonry structure 1 during an earthquake is generated. Since it can be made small and the masonry and brickwork are less likely to collapse, it is possible to reduce the collapse of the masonry structure 1.
In addition, it is preferable to provide the obstruction | occlusion part 20 also in the reinforcement structure 100 of the masonry structure shown to Fig.5 (a) (b).
また、図６（ａ）（ｂ）に示すように、芯材としての鋼管１３と、その鋼管１３の周面を覆った緩衝材１２とを有する補強部材１０であって、鋼管１３の内部にその鋼管１３よりも径の小さな小径鋼管１５が配設されており、鋼管１３と小径鋼管１５の間に粘性体１６が介在されている補強部材１０でもよい。
粘性体１６としては、例えば、シリコーンオイル系の粘性流体やアスファルト系の粘性流体を用いることができる。
本実施形態では、小径鋼管１５の内部にモルタルやグラウトなどの充填材１４を充填した。
このような粘性体１６を利用した補強部材１０が、組積造構造物１の貫通孔２内に設置されている組積造構造物の補強構造１００であれば、地震時に組積造構造物１に発生する応力をより小さくすることができ、石積みやレンガ積みが崩れ難くなるので、組積造構造物１が崩壊するのをより一層低減することができる。
なお、図６（ａ）（ｂ）に示した組積造構造物の補強構造１００にも、閉塞部２０を設けることが好ましい。
6 (a) and 6 (b), a reinforcing member 10 having a steel pipe 13 as a core material and a buffer material 12 covering the peripheral surface of the steel pipe 13 is provided inside the steel pipe 13. The small diameter steel pipe 15 having a smaller diameter than the steel pipe 13 is disposed, and the reinforcing member 10 in which the viscous body 16 is interposed between the steel pipe 13 and the small diameter steel pipe 15 may be used.
As the viscous body 16, for example, a silicone oil-based viscous fluid or an asphalt-based viscous fluid can be used.
In the present embodiment, the small diameter steel pipe 15 is filled with a filler 14 such as mortar or grout.
If the reinforcing member 10 using such a viscous body 16 is a reinforcing structure 100 of a masonry structure installed in the through hole 2 of the masonry structure 1, the masonry structure at the time of an earthquake 1 can be further reduced, and masonry and brickwork are less likely to collapse, so that the masonry structure 1 can be further prevented from collapsing.
In addition, it is preferable to provide the obstruction | occlusion part 20 also in the reinforcement structure 100 of the masonry structure shown to Fig.6 (a) (b).
なお、以上の実施の形態においては、芯材としての鋼棒１１と緩衝材１２とが一体になっている補強部材１０や、芯材としての鋼管１３と緩衝材１２とが一体になっている補強部材１０を、組積造構造物１の貫通孔２に挿し入れて設置するようにしたが、本発明はこれに限定されるものではなく、例えば、貫通孔２に鋼棒１１や鋼管１３を挿し入れた後、管状の緩衝材１２を鋼棒１１や鋼管１３に被せるように取り付けてもよい。
また、貫通孔２に鋼棒１１（鋼管１３）を挿し入れた後、貫通孔２の内壁と鋼棒１１（鋼管１３）の間に硬化性樹脂材料を流し込んで、緩衝材１２を形成するようにしてもよい。
In the above embodiment, the reinforcing member 10 in which the steel rod 11 and the buffer material 12 as the core material are integrated, or the steel pipe 13 and the buffer material 12 as the core material are integrated. The reinforcing member 10 is inserted and installed in the through hole 2 of the masonry structure 1. However, the present invention is not limited to this. For example, the steel rod 11 and the steel pipe 13 are provided in the through hole 2. After inserting, the tubular cushioning material 12 may be attached so as to cover the steel rod 11 or the steel pipe 13.
Further, after the steel rod 11 (steel pipe 13) is inserted into the through hole 2, a curable resin material is poured between the inner wall of the through hole 2 and the steel bar 11 (steel pipe 13) to form the buffer material 12. It may be.
