Description

本発明はコンクリート壁の補強用の補強部材に関する。   The present invention relates to a reinforcing member for reinforcing a concrete wall.

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。 Conventionally, various reinforcement methods have been proposed to enhance the earthquake resistance of concrete structures.
For example, after reinforcing holes are drilled in a concrete wall, the reinforcing holes are filled with a filler, the reinforcing member is inserted into the reinforcing holes, and the filler is hardened to bond the reinforcing member and the concrete wall. A method of reinforcing the shearing force of the concrete wall has been proposed.
However, if the filler is simply filled in the elongated reinforcing holes, it is difficult to remove the air mixed in the filler at the time of filling, and a gap is partially formed in the filler filled in the reinforcing holes. There is.
If the filler filled in the reinforcing hole is cured in a state where a gap is formed, the bonding strength between the reinforcing member and the concrete wall is reduced, and there is room for improvement in securing the reinforcing strength of the concrete wall.
Therefore, the applicant has a method of performing a compression 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.

特開２０１６−７００１６号公報JP, 2016-70016, A

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用の補強部材を提供することにある。 According to the above proposal, the gap partially generated in the filling material filled in the reinforcing hole is closed, the filling rate of the filling material is increased, and it is advantageous in securing the reinforcing strength of the concrete wall. .
On the other hand, the work of closing the gap partially generated in the filler is performed by rotating the rotary plate, and this work is performed in a state where the filler is semi-dried.
Therefore, the reinforcing member slightly rotates as the rotary plate rotates, which is disadvantageous in effectively compressing the filler.
Further, according to the previous application, although the structure of the reinforcing hole for preventing the rotation of the reinforcing member is also disclosed, a special hole drilling machine must be used for drilling the reinforcing hole of such a structure. Therefore, it is difficult to drill holes on site.
The present invention has been made in view of such circumstances, and an object thereof 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. An object of the present invention is to provide a reinforcing member for reinforcing a concrete wall, which is advantageous in securing strength.

次に、第１の実施の形態の補強部材１２を用いた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１０や底壁、天井壁などの壁部に適用可能である。 Next, a method for reinforcing a concrete wall using the reinforcing member 12 of the first embodiment will be described.
In addition, this Embodiment demonstrates the case where the concrete wall 10 is the side wall 10 of the box culvert which is embedded in the ground and comprises the underground tunnel for railroads.
The present invention is applicable to side walls 10 and bottom walls, ceiling walls, and other wall portions that constitute various conventionally known concrete structures such as excavated roads, retaining walls, bridge abutments, and 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. 2A, a reinforcing hole 14 extending in the thickness direction from the outer side surface 1002 of the side wall 10 of the box culvert to the side wall 10 is formed by using a punching device. Multiple holes are drilled at intervals in the height direction (drilling step).
The length of the reinforcing hole 14 is set to be slightly larger than the entire length of the reinforcing member 12.
As the perforation device, various conventionally known devices such as a drill device, a core boring device, and a water jet perforation 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２２およびロッド回転阻止部２４から各補強用孔１４に挿入し、不図示の治具を用いて定着部材２２を補強用孔１４の底部１４Ｂ（底面）に押し付けた状態とする（挿入工程）。 When the reinforcing hole 14 is drilled in the side wall 10, the inside of the reinforcing hole 14 is washed with water, and concrete fragments and dust generated by the drilling are removed from the inside of the reinforcing hole 14 (cleaning step). .
Next, as shown in FIG. 2 (B), 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 22 and the rod rotation preventing portion 24, and is The fixing member 22 is pressed against the bottom portion 14B (bottom surface) of the reinforcing hole 14 using the jig shown in the figure (inserting step).

次に、図２（Ｃ）に示すように、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）。
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を除いて充填材１６によって埋設される。
すなわち、充填材１６は、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１４０２との間に充填される。
また、充填材１６は、ロッド回転阻止部２４において、円筒面部３０Ａの内周面３００４と充填材圧縮用ロッド１８の外周面１８１０との間に充填されると共に、円筒面部３０Ａの外周面３００２と補強用孔１４の内周面１４０２との間に充填される。
また、充填材１６は、定着部材２２の周囲に充填される。 Next, as shown in FIG. 2C, the reinforcing hole 14 in which the reinforcing member 12 is inserted is filled with the filler 16 that integrally joins the reinforcing member 12 and the side wall 10 (filling step).
As the filler 16, concrete, mortar, or an adhesive can be used.
As a result, the reinforcing member 12 is embedded with the filler 16 except the base portion 1804 of the filler compression rod 18.
That is, the filler 16 is filled between the outer peripheral surface 1810 of the filler compressing rod 18 and the inner peripheral surface 1402 of the reinforcing hole 14.
Further, the filler 16 is filled between the inner peripheral surface 3004 of the cylindrical surface portion 30A and the outer peripheral surface 1810 of the filler compression rod 18 in the rod rotation preventing portion 24, and at the same time as the outer peripheral surface 3002 of the cylindrical surface portion 30A. It is filled between the reinforcing hole 14 and the inner peripheral surface 1402.
Further, the filler 16 is filled around the fixing member 22.

次に、例えば数時間経過後、充填材１６が完全に硬化する前の未硬化の状態、すなわち、充填材１６が半乾きの状態となったならば、図３（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２０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２６の補強部材挿通孔２６０２に充填材圧縮用ロッド１８を挿通し、次いで、ナット部２８の雌ねじ２８０２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２８の雌ねじ２８０２と雄ねじ１８０６を螺合することで閉塞板部２６により補強用孔１４が閉塞され、次に、図３（Ｂ）に示すように、ナット部２８を回転させることで閉塞板部２６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、充填材１６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充填材１６の内部の空気が補強用孔１４から排出され、補強用孔１４内で充填材１６が密に圧縮される。 Next, for example, after several hours have passed, if the filler 16 is in an uncured state before being completely cured, that is, if the filler 16 is in a semi-dried state, as shown in FIG. The compression rotary member 20 is attached to the base portion 1804 of the filler compression rod 18 by being positioned inside the reinforcement hole 14 on the opening 14A side of the reinforcement hole 14.
That is, the filling material compression rod 18 is inserted into the reinforcing member insertion hole 2602 of the closing plate portion 26, and then the female screw 2802 of the nut portion 28 is screwed into the male screw 1806 of the filling material compression rod 18.
The reinforcing hole 14 is closed by the closing plate portion 26 by screwing the female screw 2802 and the male screw 1806 of the nut portion 28, and then the nut portion 28 is rotated to close the reinforcing hole 14 as shown in FIG. 3B. The plate portion 26 is moved to the bottom portion 14B side of the reinforcing hole 14 in the axial direction of the filler compression rod 18 to compress the filler 16 (compression step).
As a result, the air pool formed in the upper portion of the reinforcing hole 14 and the air inside the filler 16 are discharged from the reinforcing hole 14, and the filler 16 is densely compressed in the reinforcing hole 14.

圧縮工程において圧縮用回転部材２０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、充填材１６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２０の充填材圧縮用ロッド１８の軸方向に沿った移動により充填材１６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 in which it exits from the reinforcing hole 14 with the movement of the compression rotating member 20 in the compression process, the pressure acting on the filler 16 is reduced.
Therefore, the reinforcing member 12 is pressed against the reinforcing hole 14 in the compression step by using the jig (not shown), so that the filler compressing rod 18 of the compressing rotary member 20 is moved in the axial direction. The pressure can be surely applied to the filler 16 by such movement.

また、ナット部２８の回転の際に補強部材１２がナット部２８と一体に回転すると、閉塞板部２６を補強用孔１４の底部１４Ｂ側に移動させることができず、充填材１６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２０の回転に伴って充填材圧縮用ロッド１８が回転しようとすると、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１４０２との間に充填された充填材１６による抵抗（付着抵抗）に加え、円筒面部３０Ａの内周面３００４と充填材圧縮用ロッド１８の外周面１８１０との間に充填された充填材１６による抵抗（付着抵抗）と、円筒面部３０Ａの外周面３００２と補強用孔１４の内周面１４０２との間に充填された充填材１６による抵抗（付着抵抗）との双方が生じるため、充填材圧縮用ロッド１８の回転を阻止する抵抗力として十分に機能する。
そのため、圧縮用回転部材２０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２０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に充填した充填材１６を確実に圧縮することができる。 Further, when the reinforcing member 12 rotates integrally with the nut portion 28 during the rotation of the nut portion 28, the closing plate portion 26 cannot be moved to the bottom portion 14B side of the reinforcing hole 14, and the filling material 16 is surely secured. Cannot be compressed.
In the present embodiment, when the filler compression rod 18 tries to rotate with the rotation of the compression rotation member 20, the outer peripheral surface 1810 of the filler compression rod 18 and the inner peripheral surface 1402 of the reinforcing hole 14 are separated. In addition to the resistance (adhesion resistance) due to the filling material 16 filled in between, the resistance (adhesion resistance) due to the filling material 16 filled between the inner peripheral surface 3004 of the cylindrical surface portion 30A and the outer peripheral surface 1810 of the filler compression rod 18 is provided. Resistance) and resistance (adhesion resistance) due to the filling material 16 filled between the outer circumferential surface 3002 of the cylindrical surface portion 30A and the inner circumferential surface 1402 of the reinforcing hole 14, both of which occur. It functions sufficiently as a resistance force that prevents the rotation of.
Therefore, the rotation of the reinforcing member 12 accompanying the rotation of the compression rotating member 20 is prevented, and the compression rotating member 20 can be reliably moved to the bottom portion 14B side of the reinforcing hole 14, and the reinforcing hole 14 is filled. The filler 16 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２０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３（Ｃ）に示すように、修復材３４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３４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２０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２０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３４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３４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 1804 of the filler compression rod 18 and the compression rotation member 20 are exposed inside the reinforcing hole 14 on the side of the opening 14A.
Therefore, as shown in FIG. 3C, the base 1804 of the rod 18 for compressing the filler and the reinforcing member 12 are embedded in the reinforcing hole 14 on the side of the opening 14A by filling the repairing member 34 (repairing). Process).
By embedding the base portion 1804 of the filler compression rod 18 and the compression rotary member 20 with the restoration material 34 in this manner, it is possible to prevent deterioration and corrosion of the base portion 1804 of the filler compression rod 18 and the compression rotary member 20. Will be advantageous.
In addition, the reinforcing hole 14 of the outer side surface 1002 of the side wall 10 is buried and made flat, which is advantageous in improving the appearance of the outer side surface 1002.
An epoxy resin can be used as the restoration material 34. Since the epoxy resin is excellent in waterproofness, it is advantageous in preventing the filler compression rod 18 constituting the reinforcing member 12 from being corroded and deteriorated.
Further, concrete or mortar may be used as the restoration material 34. Since concrete and mortar have excellent heat resistance and fire resistance, they are advantageous in ensuring durability in an environment where a fire is expected.

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２０の回転に伴って充填材圧縮用ロッド１８が回転しようとすると、円筒面部３０Ａの内周面３００４と外周面３００２に付着する充填材１６が抵抗となり、充填材圧縮用ロッド１８の回転を阻止する抵抗力として作用するため、圧縮用回転部材２０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２０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に充填した充填材１６を確実に圧縮することができる。
そのため、充填材１６が圧縮され空気溜まりの空気や充填材１６の内部に残る空気が抜けて充填材１６に部分的に生じていた隙間が解消され、充填材１６の充填率が高まり、補強用孔１４に充填された充填材１６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、以上の効果を補強部材１２にロッド回転阻止部２４と圧縮用回転部材２０を設けるといった簡単な構成により確実に達成でき、側壁１０の補強強度を低コストで向上させる上で有利となる。 As described above, according to the present embodiment, when the filler compression rod 18 tries to rotate with the rotation of the compression rotation member 20, the filler compression rod 18 adheres to the inner peripheral surface 3004 and the outer peripheral surface 3002 of the cylindrical surface portion 30A. Since the filling material 16 that acts as a resistance acts as a resistance force that prevents the rotation of the filling material compression rod 18, the rotation of the reinforcing member 12 accompanying the rotation of the compression rotation member 20 is prevented, and the compression rotation member 20 is prevented. The reinforcing hole 14 can be reliably moved to the bottom portion 14B side, and the filler 16 filled in the reinforcing hole 14 can be reliably compressed.
Therefore, the filler 16 is compressed, air in the air reservoir or air remaining inside the filler 16 is released, and the gap that is partially generated in the filler 16 is eliminated, the filling rate of the filler 16 is increased, and reinforcement is performed. The strength of the filling material 16 filled in the holes 14 can be increased to be solid, and as a result, the bonding strength between the reinforcing member 12 and the side wall 10 can be improved and the reinforcing strength of the side wall 10 can be ensured. Will be advantageous.
In addition, the above effect can be reliably achieved by a simple configuration in which the rod rotation blocking portion 24 and the compression rotating member 20 are provided on the reinforcing member 12, which is advantageous in improving the reinforcing strength of the side wall 10 at low cost.

（第２の実施の形態）
次に、図５（Ａ）〜（Ｃ）、図６を参照して第２の実施の形態について説明する。なお、以下の実施の形態においては、第１の実施の形態と同様の部分、部材については第１の実施の形態と同様の符号を付してその説明を省略する。
第２の実施の形態は、第１の実施の形態の変形例であり、ロッド回転阻止部２４の形状が第１の実施の形態と異なっている。
図６に示すように、筒状部材３０の外周面３００２は、補強用孔１４の内周面１４０２に近接する寸法で形成されている。
図５（Ａ）〜（Ｃ）に示すように、充填材圧縮用ロッド１８の基部１８０４側に位置する筒状部材３０の円筒面部３０Ａの端部に、基部１８０４側に至るにつれて次第に外径が小さくなる円錐面部３０Ｂが設けられている。 (Second embodiment)
Next, a second embodiment will be described with reference to FIGS. 5 (A) to 5 (C) and FIG. In the following embodiments, the same parts and members as those in the first embodiment will be designated by the same reference numerals as those in the first embodiment, and the description thereof will be omitted.
The second embodiment is a modification of the first embodiment, and the shape of the rod rotation blocking portion 24 is different from that of the first embodiment.
As shown in FIG. 6, the outer peripheral surface 3002 of the tubular member 30 is formed to have a size close to the inner peripheral surface 1402 of the reinforcing hole 14.
As shown in FIGS. 5A to 5C, at the end of the cylindrical surface portion 30A of the tubular member 30 located on the base 1804 side of the filler compression rod 18, the outer diameter gradually increases toward the base 1804 side. A smaller conical surface portion 30B is provided.

第２の実施の形態では、第１の実施の形態と同様の効果が奏されることは無論のこと以下の効果が奏される。
すなわち、筒状部材３０の円筒面部３０Ａの外径を大きくするほど、充填材１６に対する円筒面部３０Ａの内周面３００４および外周面３００２の接触面積すなわち付着面積を増大し、圧縮用回転部材２０の回転時における充填材圧縮用ロッド１８の回転を阻止する上で有利となる。
一方、筒状部材３０の円筒面部３０Ａの外径を大きくするほど、円筒面部３０Ａの外周面３００２と補強用孔１４の内周面１４０２との間の環状空間の径方向の寸法が小さくなることから充填材１６が環状空間に入り込みにくくなり、充填材１６を環状空間の全域にわたって確実に充填する上で不利となる。
このような場合、円筒面部３０Ａの端部に円錐面部３０Ｂを設けておくと、補強部材１２が挿入された補強用孔１４に充填された充填材１６は、筒状部材３０の外周面３００２と補強用孔１４の内周面１４０２との間の径方向の寸法が小さくなった環状空間に円滑に導かれ、確実に充填される。
したがって、第２の実施の形態によれば、円筒面部３０Ａの内周面３００４および外周面３００２に対する充填材１６の付着面積を増大させ、圧縮用回転部材２０の回転時における充填材圧縮用ロッド１８の回転を阻止する上で有利となり、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。 In the second embodiment, it is needless to say that the same effect as that of the first embodiment is obtained, and the following effect is obtained.
That is, as the outer diameter of the cylindrical surface portion 30A of the tubular member 30 is increased, the contact area of the inner peripheral surface 3004 and the outer peripheral surface 3002 of the cylindrical surface portion 30A with respect to the filler 16, that is, the adhesion area, is increased, and the compression rotary member 20 This is advantageous in preventing the rotation of the filler compression rod 18 during rotation.
On the other hand, as the outer diameter of the cylindrical surface portion 30A of the tubular member 30 increases, the radial dimension of the annular space between the outer peripheral surface 3002 of the cylindrical surface portion 30A and the inner peripheral surface 1402 of the reinforcing hole 14 decreases. Therefore, the filling material 16 is less likely to enter the annular space, which is disadvantageous in reliably filling the entire area of the annular space with the filling material 16.
In such a case, if the conical surface portion 30B is provided at the end of the cylindrical surface portion 30A, the filling material 16 filled in the reinforcing hole 14 into which the reinforcing member 12 is inserted will be the same as the outer peripheral surface 3002 of the tubular member 30. The reinforcing hole 14 is smoothly guided to the annular space having a smaller radial dimension between the reinforcing hole 14 and the inner peripheral surface 1402, and is reliably filled.
Therefore, according to the second embodiment, the adhesion area of the filler 16 on the inner peripheral surface 3004 and the outer peripheral surface 3002 of the cylindrical surface portion 30A is increased, and the filler compression rod 18 during rotation of the compression rotary member 20 is increased. Is advantageous in preventing the rotation of the side wall, and is advantageous in improving the coupling strength between the reinforcing member 12 and the side wall 10 and ensuring the reinforcing strength of the side wall 10.

（第３の実施の形態）
次に、図７（Ａ）、（Ｂ）を参照して第３の実施の形態について説明する。
第３の実施の形態は、第１の実施の形態の変形例であり、筒状部材３０の内周面３００４と外周面３００２に複数の凸部３８Ａや凹部３８Ｂからなる凹凸形状３８を形成したものである。
このような第３の実施の形態によれば、第１の実施の形態と同様の効果が奏されることは無論のこと以下の効果が奏される。
複数の凹凸形状３８により円筒面部３０Ａの内周面３００４および外周面３００２に対する充填材１６の付着面積を増大させ、圧縮用回転部材２０の回転時における充填材圧縮用ロッド１８の回転を阻止する上で有利となり、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。
この第３の実施の形態は、第１、第２の実施の形態に適用される。 (Third Embodiment)
Next, a third embodiment will be described with reference to FIGS. 7 (A) and 7 (B).
The third embodiment is a modification of the first embodiment, and an uneven shape 38 including a plurality of convex portions 38A and concave portions 38B is formed on the inner peripheral surface 3004 and the outer peripheral surface 3002 of the tubular member 30. It is a thing.
According to the third embodiment as described above, it is needless to say that the same effect as that of the first embodiment is obtained, and the following effect is obtained.
In addition to increasing the adhesion area of the filler 16 to the inner peripheral surface 3004 and the outer peripheral surface 3002 of the cylindrical surface portion 30A by the plurality of uneven shapes 38, preventing the rotation of the filler compression rod 18 when the compression rotation member 20 rotates. This is advantageous in improving the coupling strength between the reinforcing member 12 and the side wall 10 and ensuring the reinforcing strength of the side wall 10.
This third embodiment is applied to the first and second embodiments.

（第４の実施の形態）
次に、図８（Ａ）、（Ｂ）を参照して第４の実施の形態について説明する。
第４の実施の形態は、第１の実施の変形例であり、筒状部材３０の形状が第１の実施の形態と異なっている。
筒状部材３０の外周面３００２と内周面３００４には、筒状部材３０の軸心方向と平行する方向に延在する凸部３６Ａと凹部３６Ｂとが周方向に交互に並べられて形成されている。
本実施の形態では、凸部３６Ａと凹部３６Ｂは共に湾曲面で形成されている。
第４の実施の形態によれば、第１の実施の形態と同様の効果が奏されることは無論のこと以下の効果が奏される。
筒状部材３０の外周面３００２および内周面３００４に凸部３６Ａと凹部３６Ｂとを形成したので、第１の実施の形態に比べて充填材１６に対する筒状部材３０の外周面３００２および内周面３００４の付着面積が増大し、圧縮用回転部材２０の回転時における充填材圧縮用ロッド１８の回転を阻止する上で有利となる。
また、圧縮用回転部材２０の回転により充填材圧縮用ロッド１８が回転しようとすると、筒状部材３０の外周面３００２および内周面３００４の凸部３６Ａと凹部３６Ｂが充填材１６を押しのける方向に動くことになるので、凸部３６Ａと凹部３６Ｂにこれによる抵抗が発生し、圧縮用回転部材２０の回転時における充填材圧縮用ロッド１８の回転を阻止する上でより有利となる。
したがって、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より有利となる。
この第４の実施の形態は、第１、第２、第３の実施の形態に適用される。 (Fourth Embodiment)
Next, a fourth embodiment will be described with reference to FIGS.
The fourth embodiment is a modification of the first embodiment, and the shape of the tubular member 30 is different from that of the first embodiment.
On the outer peripheral surface 3002 and the inner peripheral surface 3004 of the tubular member 30, convex portions 36A and concave portions 36B extending in a direction parallel to the axial direction of the tubular member 30 are alternately arranged in the circumferential direction. ing.
In the present embodiment, both the convex portion 36A and the concave portion 36B are formed as curved surfaces.
According to the fourth embodiment, it goes without saying that the same effects as those of the first embodiment can be obtained, and the following effects can be obtained.
Since the convex portion 36A and the concave portion 36B are formed on the outer peripheral surface 3002 and the inner peripheral surface 3004 of the cylindrical member 30, the outer peripheral surface 3002 and the inner peripheral surface of the cylindrical member 30 relative to the filler 16 are different from those of the first embodiment. The adhesion area of the surface 3004 is increased, which is advantageous in preventing rotation of the filler compression rod 18 when the compression rotation member 20 rotates.
Further, when the filler compression rod 18 tries to rotate due to the rotation of the compression rotating member 20, the convex portions 36A and the concave portions 36B of the outer peripheral surface 3002 and the inner peripheral surface 3004 of the tubular member 30 move in the direction of pushing the filler material 16 away. Since it moves, resistance is generated in the convex portion 36A and the concave portion 36B, which is more advantageous in preventing rotation of the filler compression rod 18 when the compression rotation member 20 rotates.
Therefore, it is more advantageous in improving the bonding strength between the reinforcing member 12 and the side wall 10 and ensuring the reinforcing strength of the side wall 10.
This fourth embodiment is applied to the first, second and third embodiments.

（第５の実施の形態）
次に、図９（Ａ）、（Ｂ）、図１０を参照して第５の実施の形態について説明する。
第５の実施の形態は、第１の実施の変形例であり、補強部材１２は、第１の実施の形態と同様に、充填材圧縮用ロッド１８と、圧縮用回転部材２０と、定着部材２２と、ロッド回転阻止部２４とを備え、第１の実施の形態と異なって充填材圧縮用ロッド１８の軸心に対して筒状部材３０の軸心が偏心している。
第５の実施の形態によれば、第１の実施の形態と同様の効果が奏されることは無論のこと以下の効果が奏される。
図１０に示すように、補強用孔１４の軸心に対して、補強用孔１４に挿入された筒状部材３０の円筒面部３０Ａの軸心が偏心している。
そのため、補強用孔１４の内周面１４０２と円筒面部３０Ａの外周面３００２との距離、および、円筒面部３０Ａの内周面３００４と充填材圧縮用ロッド１８の外周面１８１０との距離が、充填材圧縮用ロッド１８の周方向において変化している。
したがって、圧縮用回転部材２０の回転時に筒状部材３０が回転しようとすると、充填材１６との接触による付着抵抗に加え、筒状部材３０は円筒面部３０Ａの外周面３００２に位置する充填材１６と円筒面部３０Ａの内周面３００４に位置する充填材１６を押しのける方向に動くことになるので、これによる抵抗が筒状部材３０に発生し、圧縮用回転部材２０の回転時における充填材圧縮用ロッド１８の回転を阻止する上で有利となり、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。
なお、この第５の実施の形態は、第１〜第４の実施の形態の全てに適用可能である。 (Fifth Embodiment)
Next, a fifth embodiment will be described with reference to FIGS. 9A, 9B, and 10.
The fifth embodiment is a modification of the first embodiment, and the reinforcing member 12 includes the filler compression rod 18, the compression rotation member 20, and the fixing member, as in the first embodiment. 22 and a rod rotation preventing portion 24, the axial center of the tubular member 30 is eccentric with respect to the axial center of the filler compression rod 18 unlike the first embodiment.
According to the fifth embodiment, it is needless to say that the same effect as that of the first embodiment is obtained, and the following effect is obtained.
As shown in FIG. 10, the axial center of the cylindrical surface portion 30A of the tubular member 30 inserted into the reinforcing hole 14 is eccentric with respect to the axial center of the reinforcing hole 14.
Therefore, the distance between the inner peripheral surface 1402 of the reinforcing hole 14 and the outer peripheral surface 3002 of the cylindrical surface portion 30A, and the distance between the inner peripheral surface 3004 of the cylindrical surface portion 30A and the outer peripheral surface 1810 of the filler compression rod 18 are filled. It changes in the circumferential direction of the material compression rod 18.
Therefore, when the tubular member 30 tries to rotate during the rotation of the compression rotary member 20, in addition to the adhesion resistance due to the contact with the filler 16, the tubular member 30 is placed on the outer peripheral surface 3002 of the cylindrical surface portion 30A. Since the filler 16 located on the inner peripheral surface 3004 of the cylindrical surface portion 30A moves in a direction to push it away, a resistance is generated in the tubular member 30 to compress the filler during rotation of the compression rotary member 20. This is advantageous in preventing the rotation of the rod 18, improving the coupling strength between the reinforcing member 12 and the side wall 10 and securing the reinforcing strength of the side wall 10.
The fifth embodiment can be applied to all of the first to fourth embodiments.

（第６の実施の形態）
次に、図１１（Ａ）、（Ｂ）を参照して第６の実施の形態について説明する。
第６の実施の形態は、ロッド回転阻止部２４の構造が第１の実施の形態と異なっている。
第６の実施の形態では、ロッド回転阻止部２４が複数の羽根板４０で構成されている。
それら羽根板４０は、定着部材２２寄りの充填材圧縮用ロッド１８の先部１８０２に充填材圧縮用ロッド１８の外周面１８１０に間隔をおいて取着され、充填材圧縮用ロッド１８の長手方向に延在している。
各羽根板４０の高さは、補強用孔１４の内周面１４０２の内径よりも小さい寸法で形成されている。
第６の実施の形態によれば、第１の実施の形態と同様に、複数の羽根板４０により充填材１６に対する付着面積が増大し、圧縮用回転部材２０の回転時における充填材圧縮用ロッド１８の回転を阻止する上で有利となる。
また、圧縮用回転部材２０の回転により充填材圧縮用ロッド１８が回転しようとすると、複数の羽根板４０が充填材１６を押しのける方向に動くことになるので、複数の羽根板４０に抵抗が発生し、圧縮用回転部材２０の回転時における充填材圧縮用ロッド１８の回転を阻止する上でより有利となる。
したがって、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より有利となる。
なお、第３の実施の形態の凹凸形状３８は、この第６の実施の形態に適用可能である。 (Sixth Embodiment)
Next, a sixth embodiment will be described with reference to FIGS. 11 (A) and 11 (B).
The sixth embodiment is different from the first embodiment in the structure of the rod rotation blocking portion 24.
In the sixth embodiment, the rod rotation blocking portion 24 is composed of a plurality of blade plates 40.
The vane plates 40 are attached to the tip portion 1802 of the filler compression rod 18 near the fixing member 22 at intervals on the outer peripheral surface 1810 of the filler compression rod 18, and the longitudinal direction of the filler compression rod 18 is increased. Has been extended to.
The height of each blade 40 is smaller than the inner diameter of the inner peripheral surface 1402 of the reinforcing hole 14.
According to the sixth embodiment, as in the first embodiment, the plurality of blade plates 40 increase the area of adhesion to the filler material 16, and the filler material compression rod when the compression rotary member 20 rotates. This is advantageous in preventing the rotation of 18.
Further, when the filler compression rod 18 tries to rotate due to the rotation of the compression rotating member 20, the plurality of blade plates 40 move in a direction to push the filler 16 away, so that resistance is generated in the plurality of blade plates 40. However, it is more advantageous in preventing the rotation of the filler compression rod 18 when the compression rotation member 20 rotates.
Therefore, it is more advantageous in improving the bonding strength between the reinforcing member 12 and the side wall 10 and ensuring the reinforcing strength of the side wall 10.
The uneven shape 38 of the third embodiment can be applied to this sixth embodiment.
