Description

本発明はコンクリート壁の補強工法に関する。 The present invention relates to a method for reinforcing concrete walls.

従来からコンクリート構造物の耐震性を強化する各種の補強工法が提案されている。
例えば、コンクリート壁に補強用孔を削孔したのち、補強用孔に充填材を充填し、補強用孔に補強部材を挿入し、充填材を硬化させることにより、補強部材とコンクリート壁とを結合させ、コンクリート壁のせん断力を補強する工法が提案されている。
しかしながら、単に充填材を細長い補強用孔に充填するのでは、充填の際に充填材に混入した空気を抜くことが難しく、補強用孔に充填された充填材には部分的に隙間が生じる場合がある。
補強用孔に充填された充填材に隙間が生じた状態で硬化すると、補強部材とコンクリート壁との結合強度が低下するため、コンクリート壁の補強強度を確保する上で改善の余地がある。
そこで、本出願人は、補強用孔への充填材の充填工程、補強用孔への補強部材の挿入工程の後に、前記補強用孔に充填された充填材を圧縮する圧縮工程を行なう工法を提案している。 Various reinforcement methods have been proposed to strengthen the earthquake resistance of concrete structures.
For example, after drilling a reinforcing hole in a concrete wall, the reinforcing hole is filled with a filler, the reinforcing member is inserted into the reinforcing hole, and the filler is hardened to join the reinforcing member and the concrete wall. A construction method has been proposed to reinforce the shear force of the concrete wall.
However, if the filling material is simply filled into the elongated reinforcing holes, it is difficult to remove the air mixed in the filling material during filling, and there may be partial gaps in the filling material filled in the reinforcing holes. There is
If the filling material filled in the reinforcing holes is hardened with gaps, the bonding strength between the reinforcing member and the concrete wall is reduced. Therefore, there is room for improvement in ensuring the reinforcing strength of the concrete wall.
Therefore, the applicant of the present invention proposed a method of performing a compressing step of compressing the filler filled in the reinforcing hole after the step of filling the reinforcing hole with the filler and the step of inserting the reinforcing member into the reinforcing hole. is suggesting.

先の提案によれば、補強用孔に充填された充填材に部分的に生じていた隙間が閉塞され、充填材の充填率が高められ、コンクリート壁の補強強度を確保する上で有利となる。
一方、充填材に部分的に生じていた隙間を閉塞する作業は、回転板を回すことでなされ、この作業は充填材の半乾きの状態で行なわれる。
そのため、回転板の回転に伴って補強部材が多少回転し、充填材を効果的に圧縮する上で不利があった。
また、先の出願によれば、補強部材の回転を阻止する補強用孔の構造も開示されているものの、このような構造の補強用孔を削孔するには特別の削孔機を使わなければならず、現場において簡単に削孔することができない。
本発明はこのような事情に鑑みなされたものであり、その目的は、補強用孔に充填した充填材を確実に圧縮でき、補強部材とコンクリート壁との結合強度を向上させ、コンクリート壁の補強強度を確保する上で有利なコンクリート壁の補強工法を提供することにある。 According to the previous proposal, the gaps partially formed in the filler filled in the reinforcement holes are closed, and the filling rate of the filler is increased, which is advantageous in securing the reinforcement strength of the concrete wall. .
On the other hand, the work of closing the gap that has partially occurred in the filler is performed by rotating the rotating plate, and this work is performed in a semi-dry state of the filler.
Therefore, the reinforcing member rotates to some extent with the rotation of the rotary plate, which is disadvantageous in terms of effectively compressing the filler.
Further, according to the previous application, a structure of reinforcing holes for preventing the rotation of the reinforcing member is also disclosed, but a special drilling machine must be used to drill the reinforcing holes of such a structure. and cannot be easily drilled on site.
SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and its object is to reliably compress the filler filled in the reinforcing hole, improve the bonding strength between the reinforcing member and the concrete wall, and reinforce the concrete wall. To provide a concrete wall reinforcement construction method advantageous in ensuring strength.

上述の目的を達成するため、本発明は、コンクリート壁に補強用孔を削孔する削孔工程と、充填材圧縮用ロッドと、前記充填材圧縮用ロッドの先端に設けられ前記充填材圧縮用ロッドよりも断面形状が大きくかつ前記補強用孔に挿入可能な大きさの定着部材とを有する補強部材を前記補強用孔に挿入する挿入工程と、前記補強用孔に充填材を充填する充填工程と、前記挿入工程、前記充填工程の後に、前記補強用孔に充填された充填材を圧縮する圧縮工程と、を備えるコンクリート壁の補強工法であって、前記充填工程の前に、前記定着部材を含む前記充填材圧縮用ロッドの先部を前記補強用孔の底部に前記充填材により回転不能に取り付ける取り付け工程を行ない、前記定着部材寄りの前記充填材圧縮用ロッドの先部に、前記充填材圧縮ロッド上で支持され前記補強用孔の内周面に対向する外周面と前記充填材圧縮ロッドの外周面に対向する内周面とを有する筒状部材が設けられている特徴とする。
本発明は、前記補強用孔の底面に対向する前記定着部材の箇所に、前記充填材圧縮用ロッドと同軸上で前記充填材圧縮用ロッドから離れるにつれて前記定着部材の断面積を次第に減少させる突起が設けられていることを特徴とする。
本発明は、前記補強部材には、前記定着部材と反対側の充填材圧縮用ロッドの基端から前記定着部材にわたって貫通する充填材供給路が設けられ、前記取り付け工程において前記充填材は、前記充填材供給路から前記補強用孔の底部に供給されることを特徴とする。 In order to achieve the above object, the present invention provides a drilling step for drilling a reinforcing hole in a concrete wall, a filler material compression rod, and a filler material compression rod provided at the tip of the filler material compression rod. an inserting step of inserting a reinforcing member having a larger cross-sectional shape than a rod and a fixing member having a size that can be inserted into the reinforcing hole into the reinforcing hole; and a filling step of filling the reinforcing hole with a filler. and a compressing step of compressing the filler filled in the reinforcing hole after the inserting step and the filling step, wherein the fixing member is inserted before the filling step. in a mounting step of non-rotatably attaching the tip of the filler material compression rod to the bottom of the reinforcing hole with the filler, A cylindrical member supported on the filler compression rod and having an outer peripheral surface facing the inner peripheral surface of the reinforcing hole and an inner peripheral surface facing the outer peripheral surface of the filler compression rod. do.
In the present invention, a protrusion is provided at a portion of the fixing member facing the bottom surface of the reinforcing hole so as to gradually decrease the cross-sectional area of the fixing member as it moves away from the filler-compressing rod coaxially with the filler-compressing rod. is provided.
In the present invention, the reinforcing member is provided with a filler supply path penetrating from the base end of the filler material compressing rod on the opposite side of the fixing member to the fixing member, and in the mounting step, the filler is It is characterized in that the filler is supplied from the filler supply path to the bottom of the reinforcing hole.

本発明によれば、圧縮用回転部材の回転に伴って充填材圧縮用ロッドが回転しようとしても、充填材により定着部材を含む充填材圧縮用ロッドの先部が補強用孔の底部に回転不能に取り付けられているので、圧縮用回転部材の回転に伴う補強部材の回転が阻止され、圧縮用回転部材を確実に補強用孔の底部側に移動させることができ、補強用孔に充填した充填材を確実に圧縮することができる。
そのため、充填材が圧縮され空気溜まりの空気や充填材の内部に残る空気が抜けて充填材に部分的に生じていた隙間が解消され、充填材の充填率が高まり、補強用孔に充填された充填材の強度を高めて密実なものとすることができ、その結果、補強部材とコンクリート壁との結合強度を向上させ、コンクリート壁の補強強度を確保する上で有利となる。 According to the present invention, even if the filler-compressing rod tries to rotate with the rotation of the compression rotating member, the tip of the filler-compressing rod including the fixing member cannot rotate due to the filler at the bottom of the reinforcing hole. Therefore, the rotation of the reinforcing member accompanying the rotation of the rotating member for compression is prevented, and the rotating member for compression can be reliably moved to the bottom side of the reinforcing hole. The material can be reliably compressed.
As a result, the filling material is compressed, and the air in the air pool and the air remaining inside the filling material escapes, eliminating the gaps partially formed in the filling material, increasing the filling rate of the filling material, and filling the reinforcing holes. As a result, the strength of the filler can be increased to make it solid, and as a result, the bonding strength between the reinforcing member and the concrete wall can be improved, which is advantageous in securing the reinforcing strength of the concrete wall .

以下、本発明の実施の形態のコンクリート壁の補強工法を図面にしたがって説明する。
まず、補強工法に用いる補強部材から説明する。
図１に示すように、補強部材１２は、後述するコンクリート壁１０の補強用孔１４（図２～図４参照）に挿入され補強用孔１４に充填された充填材１６と共にコンクリート壁１０を補強するものである。

本実施の形態では、充填材圧縮用ロッド１８として、予め全長にわたって雄ねじ１８０６が形成されたねじ節鉄筋を用いている。
なお、本実施の形態では、補強すべきコンクリート壁１０の厚さは、例えば、１００ｃｍ程度であり、補強用孔１４の内径は５ｃｍ程度、深さは９０ｃｍ程度、充填材圧縮用ロッド１８の直径は１ｃｍ～２ｃｍ程度、補強部材１２の全長は８５ｃｍ程度である。これらの寸法は、補強すべきコンクリート壁１０の厚さに対応して適宜変更される。 Filler compression rod 18 has a tip portion 1802 that is inserted into reinforcement hole 14 and an opposite base portion 1804 with external threads 1806 formed in base portion 1804 .
The filler material compression rod 18 is made of a material having sufficient rigidity to secure the reinforcing strength of the concrete wall 10 together with the filler material 16. Examples of such materials include steel materials, fiber reinforced resins, and other conventionally known various materials. materials are available.
In this embodiment, a threaded reinforcing bar having a male thread 1806 formed in advance over its entire length is used as the filling material compressing rod 18 .
In this embodiment, the thickness of the concrete wall 10 to be reinforced is, for example, about 100 cm, the inner diameter of the reinforcing hole 14 is about 5 cm, the depth is about 90 cm, and the diameter of the filling material compressing rod 18 is about 90 cm. is about 1 cm to 2 cm, and the total length of the reinforcing member 12 is about 85 cm. These dimensions are appropriately changed according to the thickness of the concrete wall 10 to be reinforced.

図１、図２（Ａ）～（Ｄ）に示すように、定着部材２０は、充填材圧縮用ロッド１８の先端に取着され、充填材１６に埋設されることで補強用孔１４の底部１４Ｂに定着する箇所である。
定着部材２０は充填材圧縮用ロッド１８の断面形状よりも大きく、かつ、補強用孔１４に挿入可能な断面形状を有している。
本実施の形態では、定着部材２０は円板状を呈しており、定着部材２０と充填材圧縮用ロッド１８は同軸上に位置している。
定着部材２０は、充填材圧縮用ロッド１８と反対側の面が補強用孔１４の底面１４０２に対向する先端面２００２となっている。 As shown in FIGS. 1 and 2(A) to 2(D), the fixing member 20 is attached to the tip of the filler compression rod 18 and embedded in the filler 16 so that the bottom of the reinforcing hole 14 is fixed. 14B is fixed.
The fixing member 20 has a cross-sectional shape that is larger than the cross-sectional shape of the filler compression rod 18 and that can be inserted into the reinforcing hole 14 .
In this embodiment, the fixing member 20 has a disc shape, and the fixing member 20 and the filling material compression rod 18 are positioned coaxially.
The fixing member 20 has a tip surface 2002 facing the bottom surface 1402 of the reinforcing hole 14 on the side opposite to the filling material compressing rod 18 .

図５に示すように、圧縮用回転部材２２は、補強用孔１４の内周面１４０４にその外周部が近接する程度の外径を有しその中心に雄ねじ１８０６に螺合する雌ねじ２６０２が貫通形成されている。
本実施の形態では、圧縮用回転部材２２は、補強用孔１４に挿入可能で補強用孔１４をほぼ閉塞する大きさの外径を有しその中心に補強部材挿通孔２４０２が形成された閉塞板部２４と、閉塞板部２４と同軸上に配置され雄ねじ１８０６に螺合可能な雌ねじ２６０２を有するナット部２６との切り離された２つの部材で構成されている。
なお、このような圧縮用回転部材２２の構成は上述の構造に限定されず、従来公知の様々な構造が採用可能である。 As shown in FIG. 5, the rotating member 22 for compression has an outer diameter that is close to the inner peripheral surface 1404 of the reinforcing hole 14, and has a female thread 2602 screwed to the male thread 1806 passing through the center thereof. formed.
In the present embodiment, the compression rotation member 22 has an outer diameter large enough to be inserted into the reinforcement hole 14 and substantially closes the reinforcement hole 14, and has a reinforcement member insertion hole 2402 formed at the center thereof. The plate portion 24 and the nut portion 26 which is arranged coaxially with the closing plate portion 24 and has an internal thread 2602 which can be screwed into the external thread 1806 are separated from each other.
In addition, the structure of such a rotating member 22 for compression is not limited to the structure described above, and various conventionally known structures can be employed.

閉塞板部２４は、硬化していない段階の可塑性を有する軟らかい充填材１６を圧縮するに足る剛性を有するものであればよく、圧縮用回転部材２２を構成する材料として、合成樹脂、ゴム、鉄鋼などの従来公知の様々な材料が使用可能である。
このように圧縮用回転部材２２が切り離された２つの部材で構成されている場合、後述する圧縮工程において、閉塞板部２４の補強部材挿通孔２４０２に補強部材１２が挿通され、ナット部２６は閉塞板部２４の補強用孔１４の開口１４Ａ側に配置されて雌ねじ２６０２が雄ねじ１８０６に螺合され、ナット部２６を回転させることで、閉塞板部２４は補強部材１２の軸方向に沿って補強用孔１４の底部１４Ｂ側に移動する。 The closing plate portion 24 may have sufficient rigidity to compress the soft filling material 16 having plasticity in an uncured stage. Various conventionally known materials can be used.
When the rotating member for compression 22 is composed of two separated members in this manner, the reinforcing member 12 is inserted through the reinforcing member insertion hole 2402 of the closing plate portion 24 in the compression step described later, and the nut portion 26 is The female screw 2602 is arranged on the opening 14A side of the reinforcing hole 14 of the closing plate portion 24 and is screwed into the male screw 1806. By rotating the nut portion 26, the closing plate portion 24 is moved along the axial direction of the reinforcing member 12. It moves to the bottom portion 14B side of the reinforcing hole 14 .

次に、第１の実施の形態に係るコンクリート壁の補強工法について説明する。
なお、本実施の形態では、コンクリート壁１０が、地中に埋設されることにより鉄道用の地下トンネルを構成するボックスカルバートの側壁１０である場合について説明する。
なお、本発明は、掘割道路、擁壁や橋梁アバット、橋脚などの従来公知の様々なコンクリート構造物を構成する側壁や底壁、天井壁などの壁部に適用可能である。 Next, a concrete wall reinforcing method according to the first embodiment will be described.
In this embodiment, concrete wall 10 is side wall 10 of a box culvert that is buried underground to constitute an underground tunnel for railways.
The present invention can be applied to walls such as side walls, bottom walls, ceiling walls, etc., which constitute various conventionally known concrete structures such as trench roads, retaining walls, bridge abutments, and bridge piers.

まず、図２（Ａ）に示すように、穿孔装置を用いてボックスカルバートの側壁１０の外側面１００２から側壁１０に厚さ方向に延在する補強用孔１４を、側壁１０の延在方向や高さ方向に間隔をおいて複数削孔する（削孔工程）。
補強用孔１４の長さは、補強部材１２の全長よりも若干大きい寸法とされる。
穿孔装置としては、ドリル装置、コアボーリング装置、ウォータジェット穿孔装置など従来公知の様々な装置が使用可能である。 First, as shown in FIG. 2(A), reinforcing holes 14 extending in the thickness direction from the outer surface 1002 of the side wall 10 of the box culvert to the side wall 10 are formed using a punching device. Multiple holes are drilled at intervals in the height direction (drilling process).
The length of the reinforcing hole 14 is slightly larger than the full length of the reinforcing member 12 .
As the drilling device, various conventionally known devices such as a drilling device, a core boring device, and a water jet drilling device can be used.

側壁１０に補強用孔１４が削孔されたならば、補強用孔１４の内部を水によって洗浄し、削孔によって発生したコンクリート片や粉塵を補強用孔１４の内部から除去する（洗浄工程）。
次に、図２（Ｂ）に示すように、補強部材１２を充填材圧縮用ロッド１８の先部１８０２、すなわち、定着部材２０から各補強用孔１４に挿入し、定着部材２０を補強用孔１４の底部１４Ｂの底面１４０２に当接させ、不図示の治具を用いて底部１４Ｂの底面１４０２に押し付けた状態とする（挿入工程）。
次に、図２（Ｃ）に示すように、定着部材２０を含む充填材圧縮用ロッド１８の先部１８０２のみを補強用孔１４の底部１４Ｂに取り付けるに足る所定量の充填材１６を、補強用孔１４の底部１４Ｂに充填する。
充填材１６としては、コンクリート、モルタル、あるいは、接着剤が使用可能である。
この充填材１６は、従来の補強用孔の全域に充填する充填材と同一材料であるが、後述する補強部材取り付け用充填材１６Ｂに比べ水分を少なくあるいはセメントを多くするなどして粘性を高くした状態で使用する。
なお、説明の便宜上、定着部材２０を含む充填材圧縮用ロッド１８の先部を補強用孔１４の底部１４Ｂに取り付けるに足る所定量の充填材１６を、先部取り付け用充填材１６Ａという。
先部取り付け用充填材１６Ａの底部１４Ｂへの充填は、例えば、充填材供給管を補強用孔１４に挿入し、補強用孔１４の底部１４Ｂに先部取り付け用充填材１６Ａを供給することで行なう。 After the reinforcing holes 14 are drilled in the side wall 10, the inside of the reinforcing holes 14 is washed with water to remove concrete pieces and dust generated by drilling from the inside of the reinforcing holes 14 (washing step). .
Next, as shown in FIG. 2B, the reinforcing member 12 is inserted into each reinforcing hole 14 from the tip portion 1802 of the filler compression rod 18, that is, the fixing member 20, and the fixing member 20 is inserted into the reinforcing hole. 14 is brought into contact with the bottom surface 1402 of the bottom portion 14B, and pressed against the bottom surface 1402 of the bottom portion 14B using a jig (not shown) (insertion step).
Next, as shown in FIG. 2C, a predetermined amount of filler 16 sufficient to attach only the tip 1802 of the filler compression rod 18 including the fixing member 20 to the bottom 14B of the reinforcing hole 14 is added for reinforcement. The bottom portion 14B of the use hole 14 is filled.
Concrete, mortar, or adhesive can be used as the filler 16 .
The filling material 16 is the same material as the filling material that fills the entire area of the conventional reinforcing hole, but has a higher viscosity by containing less water or more cement than the filling material 16B for attaching the reinforcing member, which will be described later. Use it as it is.
For convenience of explanation, a predetermined amount of filler 16 sufficient to attach the tip of the filler compression rod 18 including the fixing member 20 to the bottom 14B of the reinforcing hole 14 is referred to as a tip attachment filler 16A.
The bottom portion 14B is filled with the tip attachment filler 16A, for example, by inserting a filler supply pipe into the reinforcement hole 14 and supplying the tip attachment filler 16A to the bottom portion 14B of the reinforcement hole 14. do

これにより、定着部材２０を含む充填材圧縮用ロッド１８の先部１８０２が先部取り付け用充填材１６Ａに埋設される。
すなわち、定着部材２０を含む充填材圧縮用ロッド１８の先部の外周面１８１０と補強用孔１４の内周面１４０４との間に先部取り付け用充填材１６Ａが充填される。
このように補強部材１２を補強用孔１４に対して押さえつけた状態で先部取り付け用充填材１６Ａが完全に硬化することで、定着部材２０を含む充填材圧縮用ロッド１８の先部１８０２が補強用孔１４の底部１４Ｂに回転不能に取り付けられる（取り付け工程）。 As a result, the tip portion 1802 of the filler compression rod 18 including the fixing member 20 is embedded in the tip attachment filler 16A.
That is, the tip attachment filler 16A is filled between the outer peripheral surface 1810 of the tip of the filler compression rod 18 including the fixing member 20 and the inner peripheral surface 1404 of the reinforcing hole 14 .
By completely curing the tip attachment filler 16A while the reinforcing member 12 is pressed against the reinforcing hole 14 in this manner, the tip 1802 of the filler compression rod 18 including the fixing member 20 is reinforced. It is non-rotatably attached to the bottom portion 14B of the use hole 14 (attachment step).

なお、先部取り付け用充填材１６Ａの補強用孔１４の底部１４Ｂへの充填は、補強部材１２を補強用孔１４に挿入する前に行なってもよい。
すなわち、削孔工程の後、図３（Ａ）に示すように、先部取り付け用充填材１６Ａを補強用孔１４の底部１４Ｂへ充填したのち、図３（Ｂ）に示すように、補強部材１２を各補強用孔１４に挿入し、定着部材２０を底部１４Ａに充填されている先部取り付け用充填材１６Ａ内に押し込み、不図示の治具を用いて定着部材２０を補強用孔１４の底部１４Ｂの底面１４０２に押し付けた状態とし、先部取り付け用充填材１６Ａを硬化させて、定着部材２０を含む充填材圧縮用ロッド１８の先部１８０２を補強用孔１４の底部１４Ｂに回転不能に取り付けるようにしてもよい（取り付け工程）。 It should be noted that the bottom portion 14B of the reinforcing hole 14 may be filled with the tip attachment filler 16A before the reinforcing member 12 is inserted into the reinforcing hole 14. FIG.
That is, after the hole drilling process, as shown in FIG. 12 is inserted into each reinforcing hole 14, the fixing member 20 is pushed into the tip attachment filling material 16A filled in the bottom portion 14A, and the fixing member 20 is inserted into the reinforcing hole 14 using a jig (not shown). By pressing against the bottom surface 1402 of the bottom portion 14B, the tip attachment filler 16A is cured, and the tip portion 1802 of the filler compression rod 18 including the fixing member 20 is unrotatably attached to the bottom portion 14B of the reinforcing hole 14. You may make it attach (attachment process).

次に、図２（Ｄ）に示すように、定着部材２０を含む充填材圧縮用ロッド１８の先部１８０２が補強用孔１４の底部１４Ｂに回転不能に取り付けられて補強部材１２が挿入された補強用孔１４に、補強部材１２と側壁１０とを一体的に結合する充填材１６を充填する（充填工程）。
ここで、説明の便宜上、このように先部取り付け用充填材１６Ａの後に充填する充填材１６を補強部材取り付け用充填材１６Ｂといい、その材料は先部取り付け用充填材１６Ａと同様であるが、従来の補強用孔の全域に充填する充填材と同様な粘性にして用いる。
これにより、補強部材１２は、充填材圧縮用ロッド１８の基部１８０４を除いて先部取り付け用充填材１６Ａおよび補強部材取り付け用充填材１６Ｂによって埋設される。
すなわち、充填材１６は、定着部材２０の周囲および充填材圧縮用ロッド１８の外周面１８１０と補強用孔１４の内周面１４０４との間に充填される。 Next, as shown in FIG. 2D, the tip portion 1802 of the filler compression rod 18 including the fixing member 20 was non-rotatably attached to the bottom portion 14B of the reinforcing hole 14, and the reinforcing member 12 was inserted. The reinforcing hole 14 is filled with a filler 16 that integrally joins the reinforcing member 12 and the side wall 10 (filling step).
Here, for convenience of explanation, the filler 16 that is filled after the tip attachment filler 16A is referred to as a reinforcement member attachment filler 16B, and the material thereof is the same as that of the tip attachment filler 16A. , the viscosity is the same as that of the conventional filling material that fills the entire area of the reinforcing hole.
As a result, the reinforcing member 12 is buried by the tip attachment filler 16A and the reinforcing member attachment filler 16B except for the base portion 1804 of the filler compression rod 18 .
That is, the filler 16 is filled around the fixing member 20 and between the outer peripheral surface 1810 of the filler compression rod 18 and the inner peripheral surface 1404 of the reinforcing hole 14 .

次に、補強部材取り付け用充填材１６Ｂが完全に硬化する前の未硬化の状態、すなわち、補強部材取り付け用充填材１６Ｂが半乾きの状態となったならば、図４（Ａ）に示すように、補強用孔１４の開口１４Ａ側で補強用孔１４の内部に位置させて圧縮用回転部材２２を充填材圧縮用ロッド１８の基部１８０４に取り付ける。
すなわち、閉塞板部２４の補強部材挿通孔２４０２に充填材圧縮用ロッド１８を挿通し、次いで、ナット部２６の雌ねじ２６０２を充填材圧縮用ロッド１８の雄ねじ１８０６に螺合させる。
ナット部２６の雌ねじ２６０２と雄ねじ１８０６を螺合することで閉塞板部２４により補強用孔１４が閉塞され、次に、図４（Ｂ）に示すように、ナット部２６を回転させることで閉塞板部２４を充填材圧縮用ロッド１８の軸方向で補強用孔１４の底部１４Ｂ側に移動させ、補強部材取り付け用充填材１６Ｂを圧縮する（圧縮工程）。
これにより、補強用孔１４の上部に形成された空気溜まりや補強部材取り付け用充填材１６Ｂの内部の空気が補強用孔１４から排出され、補強用孔１４内で補強部材取り付け用充填材１６Ｂが密に圧縮される。 Next, in an uncured state before the reinforcing member mounting filler 16B is completely cured, that is, when the reinforcing member mounting filler 16B is in a half-dried state, as shown in FIG. Next, the rotating member 22 for compression is attached to the base portion 1804 of the rod 18 for compressing the filler material so as to be positioned inside the reinforcement hole 14 on the side of the opening 14A of the reinforcement hole 14 .
That is, the filler compression rod 18 is inserted into the reinforcing member insertion hole 2402 of the closing plate portion 24 , and then the female thread 2602 of the nut portion 26 is screwed into the male thread 1806 of the filler compression rod 18 .
By screwing the female thread 2602 and the male thread 1806 of the nut portion 26 together, the reinforcing hole 14 is closed by the closing plate portion 24, and then, as shown in FIG. The plate portion 24 is moved toward the bottom portion 14B of the reinforcing hole 14 in the axial direction of the filler compression rod 18 to compress the reinforcing member mounting filler 16B (compression step).
As a result, the air pool formed in the upper part of the reinforcing hole 14 and the air inside the reinforcing member mounting filler 16B are discharged from the reinforcing hole 14, and the reinforcing member mounting filler 16B is discharged from the reinforcing hole 14. densely compressed.

圧縮工程において圧縮用回転部材２２の移動に伴い補強部材１２が補強用孔１４から出る方向に変位すると、補強部材取り付け用充填材１６Ｂに対して作用する圧力が低下してしまう。
したがって、上述の不図示の治具を用いて圧縮工程において補強部材１２を補強用孔１４に対して押さえつけておき、これにより、圧縮用回転部材２２の充填材圧縮用ロッド１８の軸方向に沿った移動により補強部材取り付け用充填材１６Ｂに対して圧力を確実に加えることができる。 When the reinforcing member 12 is displaced in the direction of exiting from the reinforcing hole 14 as the rotating member 22 for compression is moved in the compression step, the pressure acting on the filling material 16B for attaching the reinforcing member is reduced.
Therefore, in the compression process, the reinforcing member 12 is pressed against the reinforcing hole 14 using the jig (not shown) described above. This movement can reliably apply pressure to the reinforcing member mounting filler 16B.

また、ナット部２６の回転の際に補強部材１２がナット部２６と一体に回転すると、閉塞板部２４を補強用孔１４の底部１４Ｂ側に移動させることができず、補強部材取り付け用充填材１６Ｂを確実に圧縮できなくなる。
本実施の形態では、圧縮用回転部材２２の回転に伴って充填材圧縮用ロッド１８が回転しようとしても、先部取り付け用充填材１６Ａにより定着部材２０を含む充填材圧縮用ロッド１８の先部１８０２が補強用孔１４の底部１４Ｂに回転不能に取り付けられているので、圧縮用回転部材２２の回転に伴う補強部材１２の回転が阻止され、圧縮用回転部材２２を確実に補強用孔１４の底部１４Ｂ側に移動させることができ、補強用孔１４に充填した補強部材取り付け用充填材１６Ｂを確実に圧縮することができる。 Further, if the reinforcing member 12 rotates integrally with the nut portion 26 when the nut portion 26 rotates, the closing plate portion 24 cannot be moved toward the bottom portion 14B of the reinforcing hole 14, and the filling material for attaching the reinforcing member cannot be moved. 16B cannot be reliably compressed.
In the present embodiment, even if the filler material compressing rod 18 tries to rotate with the rotation of the compression rotating member 22, the tip portion of the filler material compressing rod 18 including the fixing member 20 is held by the tip attachment filler 16A. Since 1802 is non-rotatably attached to the bottom portion 14B of the reinforcing hole 14, the rotation of the reinforcing member 12 accompanying the rotation of the rotating member 22 for compression is prevented, and the rotating member 22 for compression is securely positioned in the hole 14 for reinforcement. It can be moved to the bottom portion 14B side, and the reinforcing member mounting filler 16B filled in the reinforcing hole 14 can be reliably compressed.

圧縮工程後、開口１４Ａ側で補強用孔１４の内部に充填材圧縮用ロッド１８の基部１８０４および圧縮用回転部材２２が露出した状態となっている。
そこで、開口１４Ａ側の補強用孔１４の内部に、図４（Ｃ）に示すように、修復材２８を充填することで充填材圧縮用ロッド１８の基部１８０４および補強部材１２を埋設する（修復工程）。
このように修復材２８で充填材圧縮用ロッド１８の基部１８０４および圧縮用回転部材２２を埋設すると、充填材圧縮用ロッド１８の基部１８０４および圧縮用回転部材２２の劣化や腐食の防止を図る上で有利となる。
また、側壁１０の外側面１００２の補強用孔１４が埋設され平坦面とされることで、外側面１００２の美観の向上を図る上で有利となる。
修復材２８としては、エポキシ樹脂を用いることができる。エポキシ樹脂は防水性に優れているため、補強部材１２を構成する充填材圧縮用ロッド１８の腐食、劣化を防止する上で有利となる。
また、修復材２８として、コンクリートやモルタルを用いても良い。コンクリートやモルタルは耐熱性、耐火性に優れているため、火災が想定される環境下において耐久性を確保する上で有利となる。 After the compression step, the base portion 1804 of the filler compression rod 18 and the compression rotation member 22 are exposed inside the reinforcement hole 14 on the opening 14A side.
Therefore, as shown in FIG. 4C, the reinforcing hole 14 on the opening 14A side is filled with the restoration material 28 to embed the base 1804 of the filling material compression rod 18 and the reinforcement member 12 (repair process).
By embedding the base portion 1804 of the filling material compression rod 18 and the compression rotating member 22 with the restoration material 28 in this way, deterioration and corrosion of the base portion 1804 of the filling material compression rod 18 and the compression rotating member 22 can be prevented. is advantageous.
In addition, since the reinforcing holes 14 are embedded in the outer surface 1002 of the side wall 10 to form a flat surface, it is advantageous in improving the appearance of the outer surface 1002 .
Epoxy resin can be used as the repair material 28 . Since the epoxy resin is excellent in waterproofness, it is advantageous in preventing corrosion and deterioration of the filling material compressing rod 18 constituting the reinforcing member 12 .
Concrete or mortar may also be used as the repair material 28 . Concrete and mortar are excellent in heat resistance and fire resistance, so they are advantageous in ensuring durability in an environment where fire is assumed.

以上説明したように、本実施の形態によれば、圧縮用回転部材２２の回転に伴って充填材圧縮用ロッド１８が回転しようとしても、先部取り付け用充填材１６Ａにより定着部材２０を含む充填材圧縮用ロッド１８の先部１８０２が補強用孔１４の底部１４Ｂに回転不能に取り付けられているので、圧縮用回転部材２２の回転に伴う補強部材１２の回転が阻止され、圧縮用回転部材２２を確実に補強用孔１４の底部１４Ｂ側に移動させることができ、補強用孔１４に充填した補強部材取り付け用充填材１６Ｂを確実に圧縮することができる。
そのため、補強部材取り付け用充填材１６Ｂが圧縮され空気溜まりの空気や補強部材取り付け用充填材１６Ｂの内部に残る空気が抜けて補強部材取り付け用充填材１６Ｂに部分的に生じていた隙間が解消され、補強部材取り付け用充填材１６Ｂの充填率が高まり、補強用孔１４に充填された補強部材取り付け用充填材１６Ｂの強度を高めて密実なものとすることができ、その結果、補強部材１２と側壁１０との結合強度を向上させ、側壁１０の補強強度を確保する上で有利となる。
また、以上の効果を、従来使用している充填材１６を用いた取り付け工程を加えることにより簡単に達成できる。 As described above, according to the present embodiment, even if the filling material compressing rod 18 tries to rotate with the rotation of the compression rotating member 22, the filling including the fixing member 20 is prevented by the tip attachment filling material 16A. Since the tip portion 1802 of the material compression rod 18 is non-rotatably attached to the bottom portion 14B of the reinforcement hole 14, the rotation of the reinforcement member 12 accompanying the rotation of the rotation member 22 for compression is prevented, and the rotation member 22 for compression is prevented from rotating. can be reliably moved to the bottom portion 14B side of the reinforcing hole 14, and the reinforcing member mounting filler 16B filled in the reinforcing hole 14 can be reliably compressed.
As a result, the reinforcing member mounting filler 16B is compressed, the air in the air pool and the air remaining inside the reinforcing member mounting filler 16B are released, and the gap partially formed in the reinforcing member mounting filler 16B is eliminated. , the filling rate of the reinforcing member mounting filler 16B increases, the strength of the reinforcing member mounting filler 16B filled in the reinforcing hole 14 can be increased, and the reinforcing member 12 can be solidified. and the side wall 10 to improve the strength of the connection, which is advantageous in ensuring the reinforcing strength of the side wall 10 .
Moreover, the above effect can be easily achieved by adding a mounting step using the filler 16 that is conventionally used.

第５の実施の形態によれば、第１の実施の形態と同様な効果が奏される他、先部取り付け用充填材１６Ａの定着部材２０を含む充填材圧縮用ロッド１８の外周面１８１０と補強用孔１４の内周面１４０４との間への充填を簡単に確実に行なえ、取り付け工程を簡易迅速に行なう上で有利となる。 In the fifth embodiment, the tip attachment filler 16A is delivered to the distal face 2002 from the filler supply channel 38 after the insertion step and before the filling step.
That is, as shown in FIG. 10(A), after the reinforcing holes 14 are drilled in the side wall 10 and the interiors of the reinforcing holes 14 are washed with water, the reinforcing members are formed as shown in FIG. 10(B). 12 was inserted into each reinforcing hole 14 from the tip portion 1802 of the filler compression rod 18, that is, the fixing member 20, and the fixing member 20 was pressed against the bottom surface 1402 of the reinforcing hole 14 using a jig (not shown). state (insertion step).
Next, as shown in FIG. 10C, the tip attachment filler 16A is supplied from the filler supply path 38 to the tip surface 2002 of the fixing member 20. Next, as shown in FIG.
As a result, the tip portion 1802 of the filler compression rod 18 including the fixing member 20 is embedded in the tip attachment filler 16A.
That is, the tip attachment filler 16A is filled between the outer peripheral surface 1810 of the filler compression rod 18 including the fixing member 20 and the inner peripheral surface 1404 of the reinforcing hole 14 .
By completely curing the tip attachment filler 16A while the reinforcing member 12 is pressed against the reinforcing hole 14 in this manner, the tip 1802 of the filler compression rod 18 including the fixing member 20 is reinforced. It is non-rotatably attached to the bottom portion 14B of the use hole 14 (attachment step).
After curing the tip attachment filler 16A, the filling process, the compression process, and the restoration process are performed in the same manner as in the first embodiment.
According to the fifth embodiment, the same effects as those of the first embodiment are obtained. The space between the reinforcing hole 14 and the inner peripheral surface 1404 can be easily and reliably filled, which is advantageous in that the mounting process can be performed simply and quickly.
