Description

構造物の補強梁、補強工法、及び構造物Reinforcing beams of structures, reinforcement methods, and structures
　本発明は、地盤に対して下端部が固定された複数の柱部材で支持された上部構造体を有する構造物の柱部材を補強するための補強梁、補強工法及び補強梁によって補強された構造物に関する。 The present invention is a structure reinforced by a reinforcing beam, a reinforcing method, and a reinforcing beam for reinforcing a column member of a structure having an upper structure supported by a plurality of column members whose lower end is fixed to the ground. Regarding things.
　港湾や漁港においては船舶を係留するために各種の桟橋等の水中構造物が設けられている。これらの水中構造物は水底地盤に打ち込まれて水面より上に突出した複数の杭を脚柱とする下部構造体と、これらの杭で支持され水面より上に敷設された床板等からなる上部構造体とから構成される。
　上記の下部構造体である杭は一般に、海底あるいは湖底といった地盤に複数本の杭群を鉛直方向に打ち込んで構築される。また、上記の上部構造体は一般に、これら杭群の上端部に梁を複数本架設し、これら梁群の間に床板を張り渡して構築される。
　また水上、陸上を問わず架設される橋梁についても地盤に基礎を介して下端部が固定された複数の橋脚と、そのような複数の橋脚で支持された桁部とを有する構造物として構成される。 Underwater structures such as various piers are provided at ports and fishing ports to moor vessels. These underwater structures are superstructures consisting of a substructure whose pedestals are multiple piles that are driven into the bottom of the water and project above the water surface, and a floor board that is supported by these piles and laid above the water surface. It is composed of the body.
The piles, which are the above-mentioned substructures, are generally constructed by driving a group of piles vertically into the ground such as the seabed or the lake bottom. Further, the above-mentioned superstructure is generally constructed by erection of a plurality of beams at the upper end of these pile groups and extending a floor plate between these beam groups.
In addition, bridges erected on water or on land are also configured as a structure having a plurality of piers whose lower ends are fixed to the ground via a foundation and girders supported by such a plurality of piers. To.
　ところで、このような既設構造物については、以下に記載する理由から既設構造物を補強する必要がある。
　・上載加重の増大への対応
　・耐震性能の向上
　また既設構造物が水中構造物である場合には、上記に加え、更に以下の理由で補強の必要がある。
　・腐食による柱部材の減厚による水中構造物の耐力の低下
・大型船舶の桟橋への衝突に対する対応 By the way, with respect to such an existing structure, it is necessary to reinforce the existing structure for the reasons described below.
-Responding to increased loading load-Improvement of seismic performance If the existing structure is an underwater structure, it is necessary to reinforce it for the following reasons in addition to the above.
・ Decrease in yield strength of underwater structures due to thickening of column members due to corrosion ・ Response to collision of large vessels with piers
　特に、過去に設置された橋梁や杭式桟橋等の構造物の多くは、近年、想定されるようになった大地震に耐えるための設計はなされておらず、将来、大地震によって構造物が損傷を受ける可能性が高く、そのような事態に至ると社会機能に大きな影響を与えることになる。
　このため、今後発生が予想される大地震に対する対策として、既設の杭や橋脚などの柱部材で支持される構造物を耐震補強する必要性は高まっている。
　また、地震後における社会機能の迅速な回復のため、構造物は人員及び物資の輸送において非常に重要な機能を果たす。
　また、桟橋などの構造物においては近年、大型客船の入港数が増加しており、大型客船が桟橋に衝突する事故も発生している。このため、その衝撃に対する補強の必要性も高まっている。
　そして、上記の補強のための施工方法として従来から多くの提案がなされている。 In particular, many of the structures such as bridges and pile-type piers installed in the past have not been designed to withstand the large earthquakes that have come to be expected in recent years, and in the future, the structures will be damaged by large earthquakes. There is a high possibility of damage, and such a situation will have a great impact on social functions.
For this reason, as a countermeasure against large earthquakes that are expected to occur in the future, there is an increasing need for seismic retrofitting of structures supported by existing pillar members such as piles and piers.
In addition, structures play a very important role in the transportation of personnel and goods for the rapid recovery of social functions after an earthquake.
In addition, in structures such as piers, the number of large passenger ships entering the port has increased in recent years, and accidents in which large passenger ships collide with the pier have also occurred. For this reason, the need for reinforcement against the impact is also increasing.
Many proposals have been made conventionally as a construction method for the above reinforcement.
　特許文献１には、既設水中構造物の柱部材同士を水中で補強梁によって連結することで水中構造物全体の剛性を上げて水中構造物の耐荷力を向上させるための施工性に優れた補強工法が記載されている。
　この補強工法は２本の柱部材同士を補強梁で連結して補強するというものであり、図３３に示すような補強梁２０を用いて２本の柱部材を連結するものである。この補強梁２０は浮力函部３の両端に、蓋部６を設けた第１杭連結部と、蓋部７を設けた第２杭連結部とから成っている。
　この補強梁２０を用いて３本以上の柱部材を補強する際には、図３４に示すように、補強梁を上下方向に段違いで設置する必要がある。補強が必要な桟橋の多くは、桟橋から海底面までの空間が少なく、深梁設置本数が制限されることが多い。 In Patent Document 1, reinforcement with excellent workability for increasing the rigidity of the entire underwater structure and improving the load bearing capacity of the underwater structure by connecting the column members of the existing underwater structure with reinforcing beams in water. The construction method is described.
In this reinforcement method, the two column members are connected to each other by a reinforcing beam to reinforce the two column members, and the two column members are connected by using the reinforcing beam 20 as shown in FIG. 33. The reinforcing beam 20 is composed of a first pile connecting portion provided with a lid portion 6 and a second pile connecting portion provided with a lid portion 7 at both ends of the buoyancy box portion 3.
When reinforcing three or more column members by using the reinforcing beams 20, it is necessary to install the reinforcing beams in different steps in the vertical direction as shown in FIG. 34. Many of the piers that need to be reinforced have a small space from the pier to the seabed, and the number of deep beams installed is often limited.

（補強梁Ａ１）
　補強梁Ａ１の全体構造を図３に示す。
　補強梁Ａ１は補強梁本体部１０と、この補強梁本体部１０の一端に設けられた第１蓋部６と補強梁本体部１０の他端に設けられた第２蓋部７とからなる。補強梁本体部１０は筒体から構成されている。筒体としては円筒体または角筒体等を使用できるが、以下では筒体として角筒体を使用した場合の補強梁本体部１０の構成について説明する。本実施形態では、補強梁本体部１０は筒体の内部が仕切壁８、９によって仕切られており、中央区画部１０ａと左右の第１区画部１０ｂ及び第２区画部１０ｃとからなる。 (Reinforcing beam A1)
The overall structure of the reinforcing beam A1 is shown in FIG.
The reinforcing beam A1 includes a reinforcing beam main body 10, a first lid 6 provided at one end of the reinforcing beam main body 10, and a second lid 7 provided at the other end of the reinforcing beam main body 10. The reinforcing beam main body 10 is composed of a tubular body. A cylindrical body, a square cylinder, or the like can be used as the cylinder, but the configuration of the reinforcing beam main body 10 when the square cylinder is used as the cylinder will be described below. In the present embodiment, the inside of the tubular body of the reinforcing beam main body 10 is partitioned by partition walls 8 and 9, and includes a central compartment 10a, left and right first compartments 10b, and a second compartment 10c.
　前記第１蓋部６と前記第１蓋部６が設けられた前記補強梁本体部１０の一端側とは、補強梁の一端を第１の杭に取付けるための第１杭連結部４を構成する。また、前記第２蓋部７と前記第２蓋部７が設けられた補強梁本体部１０の他端側とは、補強梁の他端を第１の杭とは異なる第２の杭に取付けるための第２杭連結部５を構成する。
　そして、前記第１の杭との連結に際し、前記第１杭連結部４と前記第１の杭に取付けられる他の補強梁の第１杭連結部４とで共同して前記第１の杭を包囲する。
　なお、第１杭連結部４及び第２杭連結部５の内壁面には後述する充填材（グラウト）のずれ止め用のアンカー部材１４が設けられている。 The first lid portion 6 and one end side of the reinforcing beam main body portion 10 provided with the first lid portion 6 constitute a first pile connecting portion 4 for attaching one end of the reinforcing beam to the first pile. To do. Further, the second lid portion 7 and the other end side of the reinforcing beam main body portion 10 provided with the second lid portion 7 attach the other end of the reinforcing beam to a second pile different from the first pile. A second pile connecting portion 5 for the purpose is configured.
Then, at the time of connecting to the first pile, the first pile connecting portion 4 and the first pile connecting portion 4 of another reinforcing beam attached to the first pile jointly connect the first pile. Siege.
Anchor members 14 for preventing slippage of the filler (grout), which will be described later, are provided on the inner wall surfaces of the first pile connecting portion 4 and the second pile connecting portion 5.
　図４Ａは補強梁本体部１０の構成を説明する図であり、図４Ｂは図４ＡのＸ－Ｘ’線断面図である。
　図４Ａ、図４Ｂに示すように、補強梁Ａ１の補強梁本体部１０は前後左右の４つの壁体１４（底板）、１５（頂板）、１６（側板）と、前記壁体によって形成される内部空間を中央区画部１０ａと左右の第１区画部１０ｂと第２区画部１０ｃとに分ける仕切壁８、９とからなっている。
　中央区画部１０ａは図４Ｂに示すように側板１６、１６、底板１４及び頂板１５を有しており、浮力函部３を構成している。
　浮力函部３における頂板１５は必須ではなく、頂板１５を設けない場合には浮力函部３は容器形状となり、また、頂板１５を設けた場合には浮力函部３は密閉構造となり、いずれの場合でも浮力函部３は浮力によって補強梁Ａ１を水面に浮遊させることができる。 FIG. 4A is a diagram illustrating the configuration of the reinforcing beam main body portion 10, and FIG. 4B is a cross-sectional view taken along the line XX'of FIG. 4A.
As shown in FIGS. 4A and 4B, the reinforcing beam main body 10 of the reinforcing beam A1 is formed by the four wall bodies 14 (bottom plate), 15 (top plate), 16 (side plate) in the front, rear, left and right, and the wall bodies. It is composed of partition walls 8 and 9 that divide the internal space into a central partition 10a, left and right first compartments 10b, and a second compartment 10c.
As shown in FIG. 4B, the central compartment 10a has side plates 16, 16, a bottom plate 14, and a top plate 15, and constitutes a buoyancy box portion 3.
The top plate 15 in the buoyancy box 3 is not indispensable. If the top plate 15 is not provided, the buoyancy box 3 has a container shape, and if the top plate 15 is provided, the buoyancy box 3 has a closed structure. Even in this case, the buoyancy box 3 can float the reinforcing beam A1 on the water surface by the buoyancy.
　また、浮力函部３を密閉構造とし、浮力函部３内に注水ができるようにした場合には、浮力函部３内の空間に水や海水などの液体を注入することによって補強梁Ａ１を水面下に沈降させることができる。更に、浮力函部３を密閉構造とし、浮力函部３内に適当な量の液体を注入して補強梁の重量と浮力とをバランスさせることにより補強梁Ａ１の取り付け作業をし易くすることができる。なお、補強梁Ａ１の通常の使用形態は、水面に浮かせて所定の場所まで移動させ、次いで所定の深さまで沈めるというものであるので、浮力函部３には頂板１５を設けて密閉構造とするが、沈める作業を必要としない場合もあり、この場合には必ずしも頂板１５は設ける必要がない。 Further, when the buoyancy box 3 has a closed structure so that water can be injected into the buoyancy box 3, the reinforcing beam A1 is provided by injecting a liquid such as water or seawater into the space inside the buoyancy box 3. It can be submerged below the surface of the water. Further, the buoyancy box 3 has a closed structure, and an appropriate amount of liquid is injected into the buoyancy box 3 to balance the weight and buoyancy of the reinforcing beam, thereby facilitating the installation work of the reinforcing beam A1. it can. Since the normal usage pattern of the reinforcing beam A1 is to float it on the water surface, move it to a predetermined place, and then sink it to a predetermined depth, a top plate 15 is provided on the buoyancy box 3 to form a closed structure. However, there are cases where the submerging work is not required, and in this case, the top plate 15 does not necessarily have to be provided.
　なお、本実施形態では、補強梁本体部１０を図３に示すように仕切壁８、９によって中央区画部１０ａ、第１区画部１０ｂ及び第２区画部１０ｃに区分けした例を示したが、係る構成は本発明の補強梁においては必ずしも必須ではない。
　すなわち、補強梁本体部１０は仕切壁８、９を備えていない補強梁本体部であっても良い。
　従って、本実施形態及び後述する他の実施形態の説明においては、第１蓋部及び第２蓋部は第１区画部や第２区画部の端部に設けられる構成で示されているが、係る構成は仕切壁８、９を備えていない補強梁本体部の端部に設けられる構成に置き換えたものであって良い。 In the present embodiment, as shown in FIG. 3, the reinforcing beam main body 10 is divided into the central compartment 10a, the first compartment 10b, and the second compartment 10c by the partition walls 8 and 9. Such a configuration is not always essential in the reinforcing beam of the present invention.
That is, the reinforcing beam main body 10 may be a reinforcing beam main body not provided with the partition walls 8 and 9.
Therefore, in the description of this embodiment and other embodiments described later, the first lid portion and the second lid portion are shown with a configuration provided at the end portion of the first compartment portion or the second compartment portion. Such a configuration may be replaced with a configuration provided at the end of the reinforcing beam main body portion not provided with the partition walls 8 and 9.
　補強梁本体部１０の第１杭連結部４は第１区画部１０ｂと開閉可能な第１蓋部６とからなっており、杭に取付けられた時に、第１区画部１０ｂの端部と第１蓋部６とによって杭の半周部を覆う構造となっている。この第１杭連結部４と、前記杭に取付けられる同一構造の第１杭連結部を有する他の補強梁の第１杭連結部４とによって前記杭の全周が包囲される。 The first pile connecting portion 4 of the reinforcing beam main body portion 10 is composed of a first compartment portion 10b and a first lid portion 6 that can be opened and closed, and when attached to the pile, the end portion of the first compartment portion 10b and the first The structure is such that the half circumference of the pile is covered by the lid portion 6. The entire circumference of the pile is surrounded by the first pile connecting portion 4 and the first pile connecting portion 4 of another reinforcing beam having the first pile connecting portion of the same structure attached to the pile.
　補強梁Ａ１の第２杭連結部５の構造は杭を包囲する構造を有するものであれば良く、公知の補強梁の構造を採用することができる。
その一例を図３に示す。第２杭連結部５は杭の鉛直方向の一部を包囲して杭に取り付け可能なように開閉可能な第２蓋部７を有しており、補強梁Ａ１が杭に取付けられたときに、前記第２区画部１０ｃの端部と第２蓋部７とによって杭の全周を覆う構造となっている。 The structure of the second pile connecting portion 5 of the reinforcing beam A1 may be any structure as long as it has a structure surrounding the pile, and a known structure of the reinforcing beam can be adopted.
An example thereof is shown in FIG. The second pile connecting portion 5 has a second lid portion 7 that can be opened and closed so as to surround a part of the pile in the vertical direction and can be attached to the pile, and when the reinforcing beam A1 is attached to the pile. The structure is such that the entire circumference of the pile is covered by the end portion of the second compartment portion 10c and the second lid portion 7.
　第１杭連結部４の第１蓋部６及び第２杭連結部５の第２蓋部７はそれぞれ補強梁Ａ１の補強梁本体部１０にヒンジ継手１１、１２を介して連結されており、ボルトによって補強梁本体部１０に締結される。 The first lid portion 6 of the first pile connecting portion 4 and the second lid portion 7 of the second pile connecting portion 5 are connected to the reinforcing beam main body portion 10 of the reinforcing beam A1 via hinge joints 11 and 12, respectively. It is fastened to the reinforcing beam main body 10 by bolts.
　本発明の補強梁Ａ１は第１杭連結部４の構造及びこの第１杭連結部４の杭への取付け方法に特徴があるので、以下では、第１杭連結部４の杭への取付け方法について説明する。 Since the reinforcing beam A1 of the present invention is characterized by the structure of the first pile connecting portion 4 and the method of attaching the first pile connecting portion 4 to the pile, the method of attaching the first pile connecting portion 4 to the pile is described below. Will be described.
　図５Ａは、補強梁Ａ１を２つ用いて３本の杭（Ｐ１、Ｐ２、Ｐ３）同士を同一高さで連結する過程を示す図であり、図５Ｂは３本の杭同士を同一高さで連結した状態を示す図である。
　図５Ａ、図５Ｂに示すように、２つの補強梁Ａ１のそれぞれの第１杭連結部４が中央の杭Ｐ２の鉛直方向の一部の半周部を覆うことにより、杭Ｐ２の鉛直方向の一部の全周を包囲するようになっている。 FIG. 5A is a diagram showing a process of connecting three piles (P1, P2, P3) at the same height using two reinforcing beams A1, and FIG. 5B shows a process of connecting the three piles at the same height. It is a figure which shows the state which connected with.
As shown in FIGS. 5A and 5B, the first pile connecting portion 4 of each of the two reinforcing beams A1 covers a part of the vertical portion of the central pile P2 in the vertical direction, thereby covering one half of the vertical direction of the pile P2. It is designed to surround the entire circumference of the part.
　補強梁Ａ１の第１杭連結部４の取付け方法の各工程の詳細を図６Ａ～図６Ｇに基づいて工程順に説明する。この取付け方法では補強梁Ａ１を２つ用いるが、以下では、２つの補強梁Ａ１の一方を補強梁Ａ１と表記し、他方を補強梁Ａ１’と表記する。
　図６Ａ：補強梁Ａ１の第１蓋部６と補強梁本体端部２１とが杭Ｐ２の半周部を覆うように補強梁Ａ１を配置する。
　図６Ｂ：補強梁Ａ１’を杭Ｐ２側に引き込んで杭Ｐ２に対して補強梁Ａ１の筒体の中心軸と補強梁Ａ１’の筒体の中心軸とを一致させる。
　図６Ｃ：補強梁Ａ１’の第１蓋部６’をヒンジ継手１１’の軸回りに回転させる。
　図６Ｄ：補強梁Ａ１’の第１蓋部６’が閉合位置となるようにする。
　図６Ｅ：補強梁Ａ１’の第１蓋部６’を杭Ｐ２側に引き込み、補強梁Ａ１’の第１蓋部６’と補強梁本体端部２１’とが杭Ｐ２の半周部を覆うように補強梁Ａ１’を配置する。
　図６Ｆ：補強梁本体部１０’を杭Ｐ２側に引き込み、補強梁Ａ１’の補強梁本体端部２１’と第１蓋部６の蓋端部２２とを突き合わせると共に、補強梁Ａ１’の第１蓋部６’の蓋端部２２’と補強梁Ａ１の補強梁本体端部２１とを突き合わせる。
　図６Ｇ：補強梁Ａ１の第１蓋部６の蓋端部２２と補強梁Ａ１’の補強梁本体端部２１’とをボルト３０によって締結すると共に、補強梁Ａ１’の第１蓋部６’の蓋端部２２’と補強梁Ａ１の補強梁本体端部２１とをボルト３０によって締結する。
上述した通り、補強梁の杭連結部にはヒンジを介して開閉可能な蓋構成を備えているため、杭の周囲のスペースが狭い場合であっても、杭取付位置への補強梁の誘導の際には蓋部を開蓋しておくことで他の部位への衝突が回避でき侵入角度の調整や取付深度を変更するなど手間のかかる作業が軽減される。また侵入角度を調整しない代わりに梁本体の長さを自在に伸縮させるなどするような特別な構成も必要としないため、構成が簡素化でき強度やコスト的にも有効である。 Details of each step of the method of attaching the first pile connecting portion 4 of the reinforcing beam A1 will be described in order of steps based on FIGS. 6A to 6G. In this mounting method, two reinforcing beams A1 are used. In the following, one of the two reinforcing beams A1 will be referred to as a reinforcing beam A1 and the other will be referred to as a reinforcing beam A1'.

In the pile reinforcement structure shown in FIG. 19, the reinforcing beam D2 is between the pile P1 and the pile P3, between the pile P2 and the pile P4, between the pile P3 and the pile P5, and between the pile P4 and the pile P6. To concatenate.
（補強梁Ｄ３）
　補強梁Ｄ３を図２０Ｃに示す。この補強梁Ｄ３は、２つの補強梁Ｄ２の第１杭連結部４が包囲した杭の残りの領域を包囲する形状を有している。
この補強梁Ｄ３は図１９に示す杭補強構造において、杭Ｐ３と杭Ｐ４との間を連結する。
杭Ｐ３及び杭Ｐ４はそれぞれ２つの補強梁Ｄ２の第1杭連結部と１つの補強梁Ｄ３の第１杭連結部又は第２杭連結部とで共同して杭の全周が包囲される。 (Reinforcing beam D3)
Reinforcing beam D3 is shown in FIG. 20C. The reinforcing beam D3 has a shape that surrounds the remaining area of the pile surrounded by the first pile connecting portion 4 of the two reinforcing beams D2.
The reinforcing beam D3 connects between the pile P3 and the pile P4 in the pile reinforcing structure shown in FIG.
The entire circumference of the pile is surrounded by the first pile connecting portion of the two reinforcing beams D2 and the first pile connecting portion or the second pile connecting portion of the one reinforcing beam D3 jointly with the pile P3 and the pile P4, respectively.
　次に、複数の杭を連結する場合において、そのうちの少なくとも1本の杭を４つの補強梁の第1杭連結部で共同して包囲する補強工法の例について述べる。
図２１に示したものは９本の杭Ｐ１～Ｐ９を１２の補強梁を用いて連結したものである。このような補強工法においては図２０Ｂ及び図２０Ｃに示したような２種類の補強梁Ｄ２、Ｄ３を用いることができる。
　図２１に示すように、杭Ｐ２，杭Ｐ４、杭Ｐ６及び杭Ｐ８の全周は２つの補強梁Ｄ２の第１杭連結部と１つの補強梁Ｄ３の第１杭連結部又は第２杭連結部によって共同して包囲され、杭Ｐ９の全周は４つの補強梁Ｄ３の第１杭連結部又は第２杭連結部によって包囲される。 Next, in the case of connecting a plurality of piles, an example of a reinforcement method in which at least one of the piles is jointly surrounded by the first pile connecting portion of the four reinforcing beams will be described.
The one shown in FIG. 21 is a structure in which nine piles P1 to P9 are connected by using 12 reinforcing beams. In such a reinforcing method, two types of reinforcing beams D2 and D3 as shown in FIGS. 20B and 20C can be used.
As shown in FIG. 21, the entire circumference of the pile P2, the pile P4, the pile P6 and the pile P8 is the first pile connecting portion of the two reinforcing beams D2 and the first pile connecting portion or the second pile connecting portion of the one reinforcing beam D3. It is jointly surrounded by the portions, and the entire circumference of the pile P9 is surrounded by the first pile connecting portion or the second pile connecting portion of the four reinforcing beams D3.
　補強梁Ｃ１～Ｃ３及び補強梁Ｄ１～Ｄ３は、図に示すように、第１杭連結部４と浮力函部３とはボルト３０又は連結部材３７によって結合される構造となっており、同じく第２杭連結部５と浮力函部３ともボルト３０又は連結部材３７によって結合される構造となっている。なお、第１杭連結部と浮力函部の結合構造と第２杭連結部と浮力函部の結合構造は互いに異なる構造で結合されているものであっても良い。つまり一方の杭連結部と浮力函部はボルト、他方の杭連結部と浮力函部は連結部材といったように異なる結合構造であっても良い。
　杭に補強梁を取付ける際には、補強梁本体中央部である浮力函部３、第１杭連結部４及び第２杭連結部５を一体化させた補強梁の形態で取り付け作業を行っても良いが、浮力函部３、第１杭連結部４及び第２杭連結部５が分離した状態で用いても良い。つまり、杭Ｐ１と杭Ｐ２との間を補強梁で連結する際には、まず、第１杭連結部４を杭Ｐ１に取付けて一体化すると共に第２杭連結部を杭Ｐ２に取付けて一体化する。その後第１杭連結部４及び第２杭連結部５の間に浮力函部３を配置して、浮力函部３と第１杭連結部４及び第２杭連結部５それぞれとをボルト３０又は連結部材３７で一体化する。
このような分離構成は、各杭の間隔が長い場合、浮力函部と連結部とを一体化した状態では重量の問題等で運搬が困難な場合などにメリットがある。また連結部と浮力函部とを別体構成としておくことによって、杭間隔が変動した場合には浮力函部の構成だけを調整したもので適用できる、という利点もある。 As shown in the figure, the reinforcing beams C1 to C3 and the reinforcing beams D1 to D3 have a structure in which the first pile connecting portion 4 and the buoyancy box portion 3 are connected by a bolt 30 or a connecting member 37. The two-pile connecting portion 5 and the buoyancy box portion 3 are both connected by a bolt 30 or a connecting member 37. The connecting structure of the first pile connecting portion and the buoyancy box portion and the connecting structure of the second pile connecting portion and the buoyancy box portion may be connected by different structures. That is, one pile connecting portion and the buoyancy box may have different coupling structures such as bolts, and the other pile connecting portion and the buoyancy box may have a connecting member.
When attaching the reinforcing beam to the pile, the attachment work is performed in the form of a reinforcing beam in which the buoyancy box portion 3, the first pile connecting portion 4 and the second pile connecting portion 5 which are the central portions of the reinforcing beam main body are integrated. However, the buoyancy box portion 3, the first pile connecting portion 4 and the second pile connecting portion 5 may be used in a separated state. That is, when connecting the pile P1 and the pile P2 with a reinforcing beam, first, the first pile connecting portion 4 is attached to the pile P1 and integrated, and the second pile connecting portion is attached to the pile P2 and integrated. To become. After that, the buoyancy box portion 3 is arranged between the first pile connecting portion 4 and the second pile connecting portion 5, and the buoyancy box portion 3 and the first pile connecting portion 4 and the second pile connecting portion 5 are bolted 30 or each. It is integrated by the connecting member 37.
Such a separation configuration is advantageous when the distance between the piles is long, or when it is difficult to transport the buoyancy box portion and the connecting portion in an integrated state due to a weight problem or the like. Further, by setting the connecting portion and the buoyancy box portion as separate bodies, there is an advantage that when the pile spacing fluctuates, only the configuration of the buoyancy box portion can be adjusted and applied.

　上記で示した１本の杭を３つ又は４つの補強梁の連結部で包囲して一体化する工程においても、杭連結部と浮力函部との結合は図２２Ａ～図２２Ｉ及び図２３Ａ～図２３Ｉに示したボルト３０による連結又は図２４Ａ～２４Ｉに示した連結部材１９による連結のどちらも同様に適用し得るため、ここでは説明を割愛する。 Even in the step of surrounding and integrating one pile shown above with a connecting portion of three or four reinforcing beams, the connection between the pile connecting portion and the buoyancy box portion is shown in FIGS. 22A to 22I and 23A to 23A. Since either the connection by the bolt 30 shown in FIG. 23I or the connection by the connecting member 19 shown in FIGS. 24A to 24I can be similarly applied, the description thereof is omitted here.
　このように連結部を杭に取り付けた後、杭と補強梁の第１杭連結部との取りあい部にグラウトを注入して杭と補強梁の第１杭連結部とを一体化することは既に述べた。以下では、この一体化工程の例を図２７、図２８Ａ～図２８Ｃ、図２９Ａ～図２９Ｃに基づいて以下説明する。図２７は第１杭連結部４と杭Ｐ２との取り合い部にグラウトを注入して一体化する時の状態を示す図であり、補強梁を杭Ｐ２に取付けるに際しては予め杭Ｐ２に補強梁を支持するための支持材３１を設けられている。 After attaching the connecting portion to the pile in this way, it is possible to inject grout into the connecting portion between the pile and the first pile connecting portion of the reinforcing beam to integrate the pile and the first pile connecting portion of the reinforcing beam. Already mentioned. Hereinafter, an example of this integration step will be described below based on FIGS. 27, 28A to 28C, and 29A to 29C. FIG. 27 is a diagram showing a state when grout is injected into the joint portion between the first pile connecting portion 4 and the pile P2 to integrate them, and when the reinforcing beam is attached to the pile P2, the reinforcing beam is previously attached to the pile P2. A support member 31 for supporting is provided.
　この支持材３１の例を図２８Ａ～図２８Ｃに基づいて説明する。
　図２８Ａ～図２８Ｃに示した例では支持材３１は、４分割された受け材３３と複数の支持板３２とからなり、各受け材３３と各支持板３２は、補強梁の施工前に水中溶接又はボルトによって杭Ｐ２に取り付けておく。支持材３１は補強梁の鉛直方向の位置決めをすると共に、グラウト打設時の荷重を一時的に支持する機能を有する。図２８Ｂは図２８Ａの支持材３１の上面図である。図２８Ｂ及び図２８Ｃに示すように、受け材３３の上面にはグラウトシール３４を取り付けておく。
　また、補強梁の第１杭連結部４及び第２杭連結部５の上端部及び下端部にはグラウトの漏出を防ぐための塞ぎ板２３が設けられる。 An example of the support member 31 will be described with reference to FIGS. 28A to 28C.
In the example shown in FIGS. 28A to 28C, the support member 31 is composed of a receiving member 33 divided into four and a plurality of supporting plates 32, and each receiving member 33 and each supporting plate 32 are underwater before the construction of the reinforcing beam. It is attached to the pile P2 by welding or bolting. The support member 31 has a function of positioning the reinforcing beam in the vertical direction and temporarily supporting the load at the time of placing the grout. 28B is a top view of the support member 31 of FIG. 28A. As shown in FIGS. 28B and 28C, a grout seal 34 is attached to the upper surface of the receiving member 33.
Further, a closing plate 23 for preventing the leakage of grout is provided at the upper end and the lower end of the first pile connecting portion 4 and the second pile connecting portion 5 of the reinforcing beam.
　補強梁の杭連結部の下端部に設けられた塞ぎ板２３及び支持材３１に取り付けられたグラウトシール３４は、第１杭連結部４が杭Ｐ２を包囲したときに杭連結部と杭とによって形成される空間の下端部を塞ぐようになっている。塞ぎ板２３及びグラウトシール３４は、第１杭連結部４を杭Ｐ２に取り付けた後に、杭Ｐ２と第１杭連結部４の取り合い部にグラウトを注入して杭Ｐ２と第１杭連結部４とを一体化する際に注入したグラウトが漏出するのを防ぐ。 The grout seal 34 attached to the closing plate 23 and the support member 31 provided at the lower end of the pile connecting portion of the reinforcing beam is formed by the pile connecting portion and the pile when the first pile connecting portion 4 surrounds the pile P2. It is designed to close the lower end of the formed space. In the closing plate 23 and the grout seal 34, after the first pile connecting portion 4 is attached to the pile P2, the grout is injected into the connecting portion between the pile P2 and the first pile connecting portion 4, and the pile P2 and the first pile connecting portion 4 Prevents the injected grout from leaking when integrating with.
　上記のように、支持材３１を杭に施工すると共に、杭Ｐ２の表面にグラウトの強度を高めるために鉄筋を施工してもよい。
　図中に示した前記塞ぎ板２３は後述するように支持材３１が塞ぎ板２３を兼ねるようにする場合には、塞ぎ板２３は補強梁の杭連結部の内壁の上端部のみに設けるようにしても良い。
　なお、本願明細書では補強梁と杭とを一体化するために充填材としてグラウトを用いる場合について説明しているが、グラウトの代わりにコンクリートを用いても良い。 As described above, the support member 31 may be installed on the pile, and a reinforcing bar may be installed on the surface of the pile P2 in order to increase the strength of the grout.
As will be described later, when the support member 31 also serves as the closing plate 23, the closing plate 23 is provided only at the upper end of the inner wall of the pile connecting portion of the reinforcing beam. You may.
Although the specification of the present application describes the case where grout is used as a filler to integrate the reinforcing beam and the pile, concrete may be used instead of grout.
　図２９は支持材の他の実施態様を示す図である。この例では、図２９Ａに示した支持材３１は図２９Ｂに示すように４分割された受け材３３と複数の支持板３２とからなり、受け材３３を第１杭連結部４の形状に合わせて四角形状とし、その上に同じく四角形状の外観を有するグラウトシール３４を載置し、第１杭連結部４の壁体端部に端部部材３５を設けて、この端部部材３５と支持材３１との間をグラウトシール３４でシールしたものである。このように支持材３１が杭連結部の塞ぎ板２３を兼ねることにより、図２８に示したような杭連結部の底面側の塞ぎ板２３を省略することができる。なお、図２９Ｃではシール効果を確実にするために壁体端部に端部部材３５を設けたが、壁体の厚みが充分ある場合にはこの端部部材３５は省略することができる。
　施工後の補強梁は、引張り力に対してはボルトが抵抗し、補強梁が受ける圧縮力に対してはグラウトが抵抗する。 FIG. 29 is a diagram showing another embodiment of the support material. In this example, the support member 31 shown in FIG. 29A is composed of a receiving member 33 divided into four and a plurality of supporting plates 32 as shown in FIG. 29B, and the receiving member 33 is matched with the shape of the first pile connecting portion 4. A grout seal 34 having a square shape is placed on the grout seal 34, and an end member 35 is provided at the end of the wall body of the first pile connecting portion 4 to support the end member 35. It is sealed with a grout seal 34 between the material 31 and the material 31. Since the support member 31 also serves as the closing plate 23 of the pile connecting portion in this way, the closing plate 23 on the bottom surface side of the pile connecting portion as shown in FIG. 28 can be omitted. In FIG. 29C, the end member 35 is provided at the end of the wall in order to ensure the sealing effect, but the end member 35 can be omitted if the wall is sufficiently thick.
After construction, the bolt resists the tensile force and the grout resists the compressive force received by the reinforcing beam.

　図３０Ａは補強梁Ａ１の平面図であり、補強梁Ａ１の第２杭連結部５の第２蓋部７と塞ぎ板２３とが一体に設けられている。
　図３０Ｂは第２蓋部を閉合した状態を示し、図３０Ｃは補強梁Ａ１の正面図である。 30A to 30C show an example in which the second lid portion 7 and the closing plate 23 of the second pile connecting portion 5 of the reinforcing beam A1 are integrally provided.

　図３１Ａは塞ぎ板２３を有する第２蓋部７を閉合することによって杭Ｐ１を包囲する様子を示し、図３１Ｂは第２蓋部７によって杭Ｐ１を包囲した後、第２杭連結部５と杭Ｐ１との取り合い部にグラウトを注入して一体化した状態を示す図であり、図３１ＣのＡ－Ａ断面を示す。
　図３１Ｃは杭Ｐ１及び該杭Ｐ１に取付けられた補強梁Ａ１の正面図である。
　なお、上記では、補強梁Ａ１の第２杭連結部５における第２蓋部７と塞ぎ板２３とを一体化して設けた例を示したが、第１杭連結部４においても同様にして塞ぎ板を設けることができる。
　また、ここでは補強梁Ａ１を例に説明しているが、上述した他の実施態様に係る補強梁においても同構成を設ける事が可能である。つまり補強梁Ｄ２や補強梁Ｄ３のように柱部材を３つで包囲する場合においても、同様に分割された塞ぎ板を予め補強梁の連結部に一体化しておき、杭にとりつけて一体化した時に塞ぎ板が補強梁下端部全体を塞ぐ構成であって良い。勿論、一つの補強梁の連結部に補強梁下端部全体を覆う塞ぎ板が一体的に形成されているものであっても良い。 31A to 31C show how the second pile connecting portion of the reinforcing beam A1 shown in FIG. 30 is attached to the pile P1.

By adjusting the position of the support 31 appropriately, a part of the reinforcing beam 20 may appear on the water surface, or the reinforcing beam 20 may be attached to the pile P at a deeper position. As shown in FIG. 32F, a high reinforcing effect can be obtained by mounting the beam at a shallow position below the water surface.
　上記の実施形態では柱部材を補強梁によって３本または４本の杭を連結する場合について述べた。しかしながら、本発明の補強方法は４本以上の柱部材を補強梁によって連結する場合にも適用できる。すなわち、複数の柱部材の内、隣り合う柱部材Ｐ１～Ｐｎ（ｎ≧４）を連結する際には、柱部材Ｐ１と柱部材Ｐ２、及び、柱部材Ｐｎ－１と柱部材Ｐｎの連結には補強梁Ａ１～Ａ３を用い、柱部材Ｐ２～柱部材Ｐｎ－１の連結には補強梁Ｂ１～Ｂ３を用いることができる。 In the above embodiment, the case where three or four piles are connected to the column members by reinforcing beams has been described. However, the reinforcing method of the present invention can also be applied to the case where four or more column members are connected by reinforcing beams. That is, when connecting adjacent column members P1 to Pn (n ≧ 4) among the plurality of column members, the column member P1 and the column member P2, and the column member Pn-1 and the column member Pn are connected. Can use reinforcing beams A1 to A3, and can use reinforcing beams B1 to B3 for connecting the column members P2 to Pn-1.
　その場合、補強工法は以下の工程１）～４）を有することでなされる。
１）柱部材Ｐ１、Ｐｎを第１番目の前記補強梁及び第ｎ－１番目の前記補強梁の第２柱部材連結部によって包囲する第１の包囲工程
２）前記第１の包囲工程後、前記柱部材Ｐ１、Ｐｎと各補強梁の第２柱部材連結部との間に充填材を注入して補強梁と柱部材とを一体化する工程
３）前記柱部材Ｐ２～Ｐｎ－１を第２番目の補強梁から第ｎ－２番目の前記補強梁のそれぞれの第１柱部材連結部及び第２柱部材連結部によって包囲する第２の包囲工程
４）前記第２の包囲工程後、各柱部材Ｐ１～Ｐｎと各補強梁の第１柱部材連結部及び第２柱部材連結部との間に充填材を注入して補強梁と柱部材とを一体化する工程 In that case, the reinforcement method is performed by having the following steps 1) to 4).
1) First siege step of surrounding the column members P1 and Pn by the first reinforcing beam and the second pillar member connecting portion of the n-1st reinforcing beam 2) After the first siege step Step of injecting a filler between the column members P1 and Pn and the second column member connecting portion of each reinforcing beam to integrate the reinforcing beam and the column member 3) The column members P2 to Pn-1 are the first. Second encircling step of surrounding by the first column member connecting portion and the second column member connecting portion of the n-2nd reinforcing beam from the second reinforcing beam 4) After the second encircling step, each A step of injecting a filler between the column members P1 to Pn and the first column member connecting portion and the second column member connecting portion of each reinforcing beam to integrate the reinforcing beam and the column member.
　本発明の補強梁２０の高さ（梁高）は杭Ｐの直径よりも大きな寸法とすると共に補強梁２０を水面下の浅い杭部分に取り付けることが補強効果を高める点から好ましい。杭径が１２００ｍｍφの杭に対しては補強梁としては例えば梁高さ２０００ｍｍ、梁幅１５００ｍｍのものが使用される。梁高の高い部材を杭に被せて補強梁そのもので杭を高さ方向に補強するため、軸力の他、曲げモーメントを伝えるため杭同士を結合する効果は従来のストラットやブレースを用いるものに比べてより高いものとなる。そして、こうした効果により、少ない部材数での補強が可能となるため工期を短縮することができる。既設桟橋の補強では、施工期間の短縮化が必須であるため本発明の補強工法は特に有効である。 It is preferable that the height (beam height) of the reinforcing beam 20 of the present invention is larger than the diameter of the pile P and that the reinforcing beam 20 is attached to a shallow pile portion below the water surface to enhance the reinforcing effect. For a pile having a pile diameter of 1200 mmφ, for example, a beam having a beam height of 2000 mm and a beam width of 1500 mm is used as a reinforcing beam. Since a member with a high beam height is put on the pile and the pile is reinforced in the height direction by the reinforcing beam itself, the effect of connecting the piles to transmit the bending moment in addition to the axial force is the one using conventional struts and braces. It will be higher than that. Due to these effects, it is possible to reinforce with a small number of members, so that the construction period can be shortened. The reinforcement method of the present invention is particularly effective for reinforcing an existing pier because it is essential to shorten the construction period.
　また、地震の際には地盤は揺れの周期の特性（地震卓越周期）を示すが、補強梁によって水中構造物の杭を補強すると共に、補強梁の浮力函部内に重量のある固形材料（例えばコンクリート、礫等）を施工して水中構造物の重量付けを行い、水中構造物の固有周期を変えて地震卓越周期から水中構造物の固有周期を離すことによって耐震性を向上することができる。 In the event of an earthquake, the ground exhibits the characteristics of the shaking cycle (earthquake predominant cycle), but the reinforcement beams reinforce the piles of the underwater structure and the buoyancy of the reinforcing beams is a heavy solid material (for example). Seismic resistance can be improved by constructing concrete, gravel, etc.) to weight the underwater structure, changing the natural period of the underwater structure, and separating the natural period of the underwater structure from the seismic predominant cycle.
　以上の通りであるが、本発明は上述した実施態様に限定されるものではない。例えば、上述した実施態様の補強梁は、直線上に配列した３本又はそれ以上の柱部材の連結、もしくは互いに直交する四角形の頂点状に配置された３本又はそれ以上の柱部材の連結で説明しているが、これには限定されない。即ち、第１の柱部材と第２の柱部材とを結ぶ直線状の配列方向に対し、第１の柱部材と他の１本、もしくはそれ以上の柱部材それぞれとを結ぶ直線状の配列方向とが同一、もしくは角度をなして交差する方向に配置されるような配置、例えば３本で三角形の各頂点を形成する、４本で四辺形の頂点や台形の頂点を形成するような柱部材の配置であっても、同様に適用可能なものである。なお、ここでいう「（２つの柱部材を結ぶ）配列方向と同一」とは、当該配列方向がなす直線上は勿論、実質的に直線上と実質同一と見做せるものも含むものである。
従って補強梁本体のそれぞれの端部に設けられる連結部は、１つの柱部材を４つまたはそれ以上の連結部で共同して包囲するような形状で構成されたものであっても良い。
また上記の説明では、水中の地盤に埋め込みによって固定された複数の柱で支持された水中構造体を有する構造物の補強を例として説明しているが、下端部が地盤の基礎に固定された複数の橋脚などの柱部材で支持されている橋桁などの構造体を有する地上構造物、例えば橋梁の補強についても同様に適用できるものである。
つまり本発明は上述した実施形態に限定されず、本発明の精神を逸脱しない範囲で種々の変形が可能なものである。 As described above, the present invention is not limited to the above-described embodiment. For example, the reinforcing beam of the above-described embodiment is a connection of three or more column members arranged in a straight line, or a connection of three or more column members arranged in a quadrangular apex shape orthogonal to each other. Explained, but not limited to this. That is, with respect to the linear arrangement direction connecting the first pillar member and the second pillar member, the linear arrangement direction connecting the first pillar member and each of the other one or more pillar members. Pillar members that are arranged in the same or at an angle so that they intersect with each other, for example, three vertices form a triangular apex, and four form a quadrilateral apex or a trapezoidal apex. The arrangement of is also applicable. The term "identical to the arrangement direction (connecting the two pillar members)" as used herein includes not only the straight line formed by the arrangement direction but also those that can be regarded as substantially the same as the straight line.
Therefore, the connecting portion provided at each end of the reinforcing beam main body may be configured so as to jointly surround one column member with four or more connecting portions.
Further, in the above description, reinforcement of a structure having an underwater structure supported by a plurality of columns fixed by embedding in the underwater ground is described as an example, but the lower end portion is fixed to the foundation of the ground. Similarly, it can be applied to the reinforcement of a ground structure having a structure such as a bridge girder supported by a plurality of column members such as piers, for example, a bridge.
