Description

本発明は、海岸や河岸に構築した既存の護岸や岸壁などの海岸河岸既存施設と残置型枠ブロックとを、所定の間隔を空けて接続する残置型枠ブロック用接続金具に関する。   The present invention relates to a connector for a residual formwork block, which connects an existing shorebank existing facility such as a revetment or a quay built on a seashore or a riverbank with a residual formwork block at a predetermined interval.

海岸河岸既存施設、例えば海岸に構築したコンクリート製の岸壁は、経年劣化や自然災害などにより破損することがある。そのため、破損した岸壁を補修する作業を行わなくてはならない。岸壁の補修は、破損した岸壁を撤去し、撤去した後に新たにコンクリートを打設して岸壁を構築している。   An existing coastal bank facility, for example, a concrete quay constructed on the coast, may be damaged due to aging or natural disasters. Therefore, it is necessary to repair the damaged quay. To repair the quay, the damaged quay is removed, and after removing it, concrete is poured to construct a quay.

ところが、この補修は、破損した岸壁の撤去、撤去したコンクリートなどの瓦礫の処分、さらには水中において新たにコンクリートを打設して岸壁を構築しなければならず、それらの作業に手間やコストが掛かり、工期も長くなるという問題がある。   However, this repair involves removing the damaged quay, disposal of the rubble such as the removed concrete, and furthermore, placing a new concrete in the water to construct the quay, which requires labor and cost for the work. The problem is that it takes a long time to complete the work.

そこで、従来、岸壁を補修する場合、破損した岸壁を撤去することなく、コンクリート製の残置型枠ブロックを破損した岸壁の前方（陸側からみて前方）に積み上げて、新たな岸壁を構築することで、破損した岸壁の撤去やコンクリートなどの瓦礫の処分をなくして作業を容易にし、工期の短縮を図るようにしている。   Therefore, when repairing a wharf conventionally, build up a new wharf by stacking a concrete residual formwork block in front of the damaged wharf (forward as viewed from the land side) without removing the damaged wharf. Therefore, removal of the damaged quay and disposal of rubble such as concrete are eliminated to facilitate the work and shorten the construction period.

図９、図１０は、従来の岸壁の補修の作業工程を示す説明図である。
岸壁の補修は、陸上からクレーンなどにより残置型枠ブロック３を吊り上げて、図９Ａに示すように、吊り上げた残置型枠ブロック３を水中へと投入し、破損した岸壁２の前方に所定の間隔を空けて設置する。残置型枠ブロック３を設置した後、図９Ｂに示すように、岸壁２に取り付けたアンカー鉄筋５１と残置型枠ブロック３に取り付けた連結鉄筋５２とを溶接して接合する。 FIG. 9, FIG. 10 is explanatory drawing which shows the operation | work process of repair of the conventional wharf.
To repair the quay, the remaining formwork block 3 is lifted by land crane or the like, and the lifted remaining formwork block 3 is thrown into the water as shown in FIG. 9A, and a predetermined distance in front of the damaged quay 2 Clear and set up. After the residual form block 3 is installed, as shown in FIG. 9B, the anchor reinforcing bar 51 attached to the quay 2 and the connected reinforcing bar 52 attached to the residual form block 3 are welded and joined.

次に、設置した一段目の残置型枠ブロック３の上に、二段目の残置型枠ブロック３を設置し、一段目と同様、岸壁２側のアンカー鉄筋５１と残置型枠ブロック３側の連結鉄筋５２とを溶接して接合する。図９Ｃに示すように、残置型枠ブロック３の設置を上方に複数段にわたって行うことで、残置型枠ブロック３を岸壁２の前方に積み上げ、図１０Ａに示すように、最上段まで積み上げる。   Next, the second stage residual mold block 3 is installed on the first stage residual mold block 3 installed, and the anchor rebar 51 on the quay 2 side and the residual mold block 3 side as in the first stage. Welding and joining with the connected reinforcing bars 52. As shown in FIG. 9C, the residual form block 3 is placed on a plurality of stages in the upper direction to stack the residual form block 3 in front of the quay 2 and to the top as shown in FIG. 10A.

残置型枠ブロック３を最上段まで積み上げた後、次に、図１０Ｂに示すように、岸壁２と残置型枠ブロック３との間に水中コンクリート５３を打設する。最上段の残置型枠ブロック３まで水中コンクリート５３を打設した後、図１０Ｃに示すように、岸壁２の上部工５４を構築することで、新たな岸壁が完成する。   After the residual form block 3 is stacked to the uppermost stage, next, underwater concrete 53 is cast between the quay 2 and the residual form block 3 as shown in FIG. 10B. After pouring the underwater concrete 53 up to the remaining formwork block 3 of the uppermost stage, as shown in FIG. 10C, a new quay is completed by constructing the superstructure 54 of the quay 2.

ところで、岸壁の補修は、岸壁２とその前方に設置する残置型枠ブロック３とを接続するため、岸壁２に取り付けたアンカー鉄筋５１と残置型枠ブロック３に取り付けた連結鉄筋５２とを溶接して接合しているが、岸壁２と残置型枠ブロック３との接続が非常に面倒な作業となる虞がある。   By the way, repair of the wharf welds the anchor rebar 51 attached to the wharf 2 and the connection rebar 52 attached to the remaining formwork block 3 in order to connect the wharf 2 and the remaining form block 3 installed in front of it. The connection between the quay 2 and the residual formwork block 3 may be a very troublesome operation.

即ち、岸壁２とその前方に設置する残置型枠ブロック３とにおいて、施工誤差による位置ズレが発生する場合があり、この位置ズレが大きいと、岸壁２側のアンカー鉄筋５１と残置型枠ブロック３側の連結鉄筋５２とを溶接することができなくなる。そのため、岸壁２と残置型枠ブロック３とを接続することができないという問題が生じる。また、アンカー鉄筋５１と連結鉄筋５２との溶接は、水中で行うことから、その作業性が悪く、溶接作業に多大な時間を要してしまう。しかも、水中での溶接作業は熟練を要するため、熟練度の低い作業員であると、全体の作業に支障をきたす虞もでてくる。   That is, in the quay 2 and the residual form block 3 installed in front of it, positional deviation due to construction error may occur. If this positional deviation is large, the anchor rebar 51 on the quay 2 side and the residual form block 3 It becomes impossible to weld with the side connection rebar 52. Therefore, the problem that the quay 2 and the residual form block 3 can not be connected arises. In addition, since welding between the anchor reinforcing bars 51 and the connecting reinforcing bars 52 is performed in water, the workability is poor, and it takes much time for the welding operation. In addition, since the welding operation in water requires skill, if it is a low-skilled worker, the entire operation may be hindered.

本発明は、このような問題に鑑みてなされたものであって、その目的は、海岸河岸既存施設である岸壁とその前方に設置する残置型枠ブロックとを接続する際に、施工誤差による位置ズレが発生した場合でも、これらを確実に接続することができ、かつその作業を極めて容易に行うことができる残置型枠ブロック用接続金具を提供することである。   This invention is made in view of such a problem, The objective is the position by a construction error, when connecting the quay which is a shore bank existing facility and the residual form block installed in the front. It is an object of the present invention to provide a connector for a residual mold block, which can securely connect even when displacement occurs and which can be extremely easily performed.

本発明によれば、海岸河岸既存施設の補修において、海岸河岸既存施設とその前方に設置した残置型枠ブロックとを接続する際に、海岸河岸既存施設と残置型枠ブロックにおいて施工誤差による位置ズレが発生しても、残置型枠ブロック用接続金具での調整を行うことで、残置型枠ブロック用接続金具により、海岸河岸既存施設と残置型枠ブロックを確実に接続することができる。
また、残置型枠ブロック用接続金具を用いた海岸河岸既存施設と残置型枠ブロックとの接続は、残置型枠ブロック用接続金具での調整と、接続部材に第一回転体及び第二回転体を調整された回転位置で固定するだけの簡単な作業で行うことができ、作業性の向上を図ることができる。 According to the present invention, when repairing an existing coastal riparian facility, when connecting an existing coastal riparian facility with the residual formwork block installed in front of it, positional deviation due to a construction error in the coastal riparian existing facility and the residual formwork block Even if a problem occurs, by performing adjustment with the connection brackets for the remaining formwork block, it is possible to reliably connect the existing shorebank facility and the remaining formwork block by the connection fitting for the remaining formwork block.

図１は、本実施形態の残置型枠ブロック用接続金具１の斜視図である。
残置型枠ブロック用接続金具１は、図示のように、長さ調整可能な接続部材１０と、第一回転体１１及び第二回転体１２とを有する。ここでは、長さ調整可能な接続部材１０はターンバックルであるとして説明するが、長さが調整可能であれば、必ずしもターンバックルに限らない。
ターンバックル１０は、軸部材１３と、軸部材１３の両側に軸方向に移動自在かつ旋回自在に取り付けた第一部材１４及び第二部材１５を有し、全長が伸縮自在である。第一回転体１１及び第二回転体１２は、それぞれターンバックル１０の一方側及び他方側に取り付けられている。 FIG. 1 is a perspective view of the residual mold block connecting fitting 1 of the present embodiment.
As shown in the figure, the residual mold block connecting fitting 1 has a length-adjustable connecting member 10 and a first rotating body 11 and a second rotating body 12. Here, although the length adjustable connecting member 10 is described as a turnbuckle, it is not necessarily limited to the turnbuckle as long as the length can be adjusted.
The turnbuckle 10 has a shaft member 13 and a first member 14 and a second member 15 axially and movably and pivotally mounted on both sides of the shaft member 13, and the entire length is telescopic. The first rotating body 11 and the second rotating body 12 are attached to one side and the other side of the turnbuckle 10, respectively.

第一回転体１１は、ターンバックル１０の第一部材１４に回転自在に取り付けた回転部材２５を有し、回転部材２５には、アンカー鉄筋２４が取り付けられている。また、第二回転体１２は、ターンバックル１０の第二部材１５に回転自在に取り付けた回転部材３４を有し、回転部材３４には連結鉄筋３３が取り付けられている。   The first rotating body 11 has a rotating member 25 rotatably attached to the first member 14 of the turnbuckle 10, and an anchor reinforcing bar 24 is attached to the rotating member 25. Further, the second rotating body 12 has a rotating member 34 rotatably attached to the second member 15 of the turnbuckle 10, and the connecting reinforcing bar 33 is attached to the rotating member 34.

図２は、残置型枠ブロック用接続金具１のターンバックル１０の斜視図である。
ターンバックル１０は、図示のように、軸部材１３と第一部材１４と第二部材１５から成る。軸部材１３は、軸方向中央部の一方側及び他方側にそれぞれ逆向きのネジを備えたネジ棒であり、ここでは、軸方向中央部を境に、例えば一方側を右ネジにし他方側を左ネジにする。第一部材１４は軸部材１３の一方側のネジに螺合する。第二部材１５は軸部材１３の他方側のネジに螺合する。これにより、第一部材１４及び第二部材１５は、軸部材１３の両側に軸方向に移動自在かつ旋回自在に取り付けられる。
また、軸部材１３には、その軸方向中央部に軸方向と直交する方向に丸棒状の回転用レバー１６が取り付けられている。 FIG. 2 is a perspective view of the turnbuckle 10 of the connection fitting 1 for remaining mold block.
The turnbuckle 10 comprises a shaft member 13, a first member 14 and a second member 15 as shown. The shaft member 13 is a screw rod provided with screws in opposite directions on one side and the other side of the axial center portion, and here, for example, one side is a right-handed thread and the other side Make it a left hand screw. The first member 14 is screwed into a screw on one side of the shaft member 13. The second member 15 is screwed into the other screw of the shaft member 13. Thereby, the first member 14 and the second member 15 are attached to both sides of the shaft member 13 so as to be axially movable and pivotable.
Further, a round rod-like rotation lever 16 is attached to the shaft member 13 at a central portion in the axial direction in a direction orthogonal to the axial direction.

第一部材１４は、平らな面のプレート部１７から成る板状である。プレート部１７には、軸部材１３の一方側に螺合する雌ネジが形成された六角パイプ部１８が接合されている。六角パイプ部１８は、その断面の上下中央部においてプレート部１７に溶着や接着などの適宜手段で接合されている。プレート部１７には、その面に直交する方向にボルト挿通孔１９が設けられている。   The first member 14 is a plate having a flat surface plate portion 17. A hexagonal pipe portion 18 having a female screw formed on one side of the shaft member 13 is joined to the plate portion 17. The hexagonal pipe portion 18 is joined to the plate portion 17 by an appropriate means such as welding or adhesion at the upper and lower central portions of the cross section. The plate portion 17 is provided with bolt insertion holes 19 in the direction orthogonal to the surface.

また、第二部材１５も第一部材１４と同様に、平らな面のプレート部２１から成る板状である。プレート部２１には、軸部材１３の他方側に螺合する雌ネジが形成された六角パイプ部２２が接合されている。六角パイプ部２２は、その断面の上下中央部においてプレート部２１に溶着や接着などの適宜手段で接合されている。プレート部２１には、その面に直交する方向にボルト挿通孔２３が設けられている。   Further, the second member 15 is also in the form of a plate having a flat plate portion 21 as in the first member 14. A hexagonal pipe portion 22 formed with a female screw to be screwed to the other side of the shaft member 13 is joined to the plate portion 21. The hexagonal pipe portion 22 is joined to the plate portion 21 at an upper and lower central portion of the cross section by an appropriate means such as welding or adhesion. The plate portion 21 is provided with a bolt insertion hole 23 in a direction orthogonal to the surface.

ターンバックル１０は、回転操作手段である回転用レバー１６を用いて軸部材１３を回転させて、第一部材１４と第二部材１５を軸部材の軸方向に移動させることで全長が伸縮し、その長さが微調整される。即ち、軸部材１３を回転方向の一方に回転させることで、軸部材１３に螺合する第一部材１４と第二部材１５が互いに近づき、ターンバックル１０の全長が短くなり、軸部材１３を逆方向に回転させることで、軸部材１３に螺合する第一部材１４と第二部材１５が互いに離れ、ターンバックル１０の全長が長くなる。   The turnbuckle 10 rotates the shaft member 13 using the rotation lever 16 which is a rotation operation means, and moves the first member 14 and the second member 15 in the axial direction of the shaft member, thereby extending and contracting the entire length. Its length is fine-tuned. That is, by rotating the shaft member 13 in one of the rotational directions, the first member 14 and the second member 15 screwed to the shaft member 13 approach each other, the overall length of the turnbuckle 10 becomes short, and the shaft member 13 is reversed. By rotating in the direction, the first member 14 and the second member 15 screwed to the shaft member 13 are separated from each other, and the total length of the turnbuckle 10 becomes long.

図３は、残置型枠ブロック用接続金具１の第一回転体１１の斜視図である。
第一回転体１１は、図示のように、その一端側にネジ２６が形成されたアンカー鉄筋２４が螺合する回転部材２５から成る。アンカー鉄筋２４の他端側は破損したコンクリート製の岸壁に予め埋め込んで取り付けられている。
このようにアンカー鉄筋２４を回転部材２５に螺合して取り付けることで、第一回転体１１の回転部材２５は、岸壁に対して旋回可能となる。 FIG. 3 is a perspective view of the first rotary body 11 of the connection fitting 1 for remaining mold block.
As shown, the first rotating body 11 is composed of a rotating member 25 in which an anchor bar 24 having a screw 26 formed on one end side is screwed. The other end side of the anchor rebar 24 is embedded in advance and attached to the broken concrete quay.
By screwing and attaching the anchor rebar 24 to the rotation member 25 in this manner, the rotation member 25 of the first rotation body 11 can turn relative to the quay.

アンカー鉄筋２４は、長さの異なる複数のものを用意しておき、破損した岸壁と残置型枠ブロック間の距離に応じて最適な長さのものを選んで、予め岸壁に取付けておく。即ち、岸壁とその前方に設置する残置型枠ブロックとの間隔が広いときは、長いアンカー鉄筋２４を、また、岸壁と残置型枠ブロックとの間隔が狭いときは、短いアンカー鉄筋２４を選択し、予め岸壁に取り付けておく。   A plurality of anchor rebars 24 having different lengths are prepared, and those having an optimum length are selected in advance according to the distance between the damaged quaywall and the remaining formwork block, and are attached to the quay in advance. That is, when the distance between the quay and the residual formwork block installed in front of it is wide, the long anchor rebar 24 is selected, and when the distance between the quay and the residual formwork block is narrow, the short anchor rebar 24 is selected. Attached to the quay beforehand.

回転部材２５は、図示のように、平らな面のプレート部２７から成る板状で、雌ネジが形成された六角パイプ部２８がその断面の上下中央部でプレート部２７に溶着や接着などの適宜手段で接合されている。六角パイプ部２８には、アンカー鉄筋２４のネジ２６が螺合される。プレート部２７には、その面に直交する方向にボルト挿通孔２９が設けられている。   The rotating member 25 is a plate having a flat surface plate portion 27 as shown in the figure, and a hexagonal pipe portion 28 formed with a female screw is welded or adhered to the plate portion 27 at the upper and lower center portions of its cross section. It is joined by an appropriate means. The screw 26 of the anchor rebar 24 is screwed into the hexagonal pipe portion 28. The plate portion 27 is provided with bolt insertion holes 29 in a direction orthogonal to the surface.

第一回転体１１の回転部材２５は、ターンバックル１０の第一部材１４に対してそれぞれの面同士が回転自在に取り付けられる。即ち、回転部材２５のプレート部２７と、ターンバックル１０の第一部材１４のプレート部１７とを重ね合わせ、それぞれに設けたボルト挿通孔２９，１９に、締結手段ここではボルト３１を挿通する。これにより、第一回転体１１の回転部材２５をターンバックル１０の第一部材１４に対しボルト３１を中心にして回転自在（回転方向は、図中に矢印で示す）にするとともに、ボルト３１にナット３２を締結することで、調整された回転位置（任意の回転位置）で第一回転体１１をターンバックル１０に固定することができる。   The rotary members 25 of the first rotary body 11 are rotatably attached to the first member 14 of the turnbuckle 10. That is, the plate portion 27 of the rotating member 25 and the plate portion 17 of the first member 14 of the turnbuckle 10 are overlapped, and the bolt 31 is inserted through the fastening means, here, into the bolt insertion holes 29 and 19 provided respectively. As a result, the rotating member 25 of the first rotating body 11 is rotatable relative to the first member 14 of the turnbuckle 10 about the bolt 31 (the direction of rotation is indicated by the arrow in the figure). By fastening the nut 32, the first rotary body 11 can be fixed to the turnbuckle 10 at the adjusted rotational position (arbitrary rotational position).

第一回転体１１は、長さの異なる複数のアンカー鉄筋２４の中から最適な長さとなるアンカー鉄筋２４を選んで、これを回転部材２５に螺合して取り付けて使用する。これにより、アンカー鉄筋２４の回転部材２５への取り付けを容易にし、作業に手間がかからないようにすることができる。   The first rotating body 11 selects an anchor rebar 24 having an optimum length from among a plurality of anchor rebars 24 having different lengths, and uses it by screwing to the rotating member 25. Thereby, the attachment to the rotation member 25 of the anchor rebar 24 can be made easy, and it can be made for work not to take time and effort.

図４は、残置型枠ブロック用接続金具１の第二回転体１２の斜視図である。
第二回転体１２は、図示のように、連結鉄筋３３が接合された回転部材３４から成る。連結鉄筋３３は、その一端側が回転部材３４に溶着や接着などの適宜手段で接合して取り付けられるとともに、他端側にネジ３５が形成されており、ネジ３５は破損した岸壁の前方に設置した残置型枠ブロックに螺合して取り付けられる。
このように連結鉄筋３３が残置型枠ブロックに螺合して固着することで、第二回転体１２の回転部材３４は、残置型枠ブロックに対して旋回可能となる。 FIG. 4 is a perspective view of the second rotary body 12 of the connection fitting 1 for remaining mold block.
The second rotating body 12 is comprised of a rotating member 34 to which a connecting rebar 33 is joined as shown.

第二回転体１２の回転部材３４は、ターンバックル１０の第二部材１５に対してそれぞれの面同士が回転自在に取り付けられる。即ち、回転部材３４のプレート部３６と、ターンバックル１０の第二部材１５のプレート部２１とを重ね合わせ、それぞれに設けたボルト挿通孔３７，２３にボルト３１（締結手段）を挿通する。これにより、第二回転体１２の回転部材３４をターンバックル１０の第二部材１５に対しボルト３１を中心にして回転自在（回転方向は、図中に矢印で示す）にするとともに、ボルト３１にナット３２を締結することで、調整された回転位置（任意の回転位置）で第二回転体１２をターンバックル１０に固定することができる。   The rotary members 34 of the second rotary body 12 are rotatably attached to the second member 15 of the turnbuckle 10. That is, the plate portion 36 of the rotating member 34 and the plate portion 21 of the second member 15 of the turnbuckle 10 are superimposed, and the bolt 31 (fastening means) is inserted into the bolt insertion holes 37 and 23 provided in each. As a result, the rotating member 34 of the second rotating body 12 is rotatable with respect to the second member 15 of the turnbuckle 10 about the bolt 31 (the direction of rotation is indicated by the arrow in the figure). By fastening the nut 32, the second rotary body 12 can be fixed to the turnbuckle 10 at the adjusted rotational position (arbitrary rotational position).

なお、ここでは、締結手段は、ボルト３１とナット３２であるが、これに限定されず、締結できるものであれば、その他のものでもよい。
また、ターンバックル１０の第一部材１４及び第二部材１５、第一回転体１１の回転部材２５、第二回転体１２の回転部材３４は、本実施形態では、平らな面のプレート部から成る板状であるが、形状はこれに限定されず、例えば、ブロック状でもよい。 In addition, although a fastening means is bolt 31 and nut 32 here, it is not limited to this, as long as it can fasten, it may be other things.
Further, in the present embodiment, the first member 14 and the second member 15 of the turnbuckle 10, the rotating member 25 of the first rotating body 11, and the rotating member 34 of the second rotating body 12 are formed of flat plate portions. Although it is plate shape, a shape is not limited to this, For example, block shape may be sufficient.

次に、岸壁の補修において、本実施形態の残置型枠ブロック用接続金具を用いて行う岸壁とその前方に設置した残置型枠ブロックとの接続について説明する。
図５Ａは、残置型枠ブロック用接続金具１で岸壁２と残置型枠ブロック３を接続する工程において、それぞれ岸壁２及び残置型枠ブロック３に取り付けた第一回転体１１と第二回転体１２を示す平面図、図５Ｂは、図５Ａにさらにターンバックル１０を含めて示した平面図である。
また、図６Ａは、残置型枠ブロック用接続金具１で岸壁２及び残置型枠ブロック３を接続した状態を示す平面図であり、図６Ｂはその側面図である。 Next, in the repair of the wharf, the connection between the wharf and the remaining formwork block installed in front of the same will be described using the remaining formwork block connector of this embodiment.
FIG. 5A shows the first rotating body 11 and the second rotating body 12 attached to the quay 2 and the remaining formwork block 3 in the step of connecting the quay 2 and the remaining formwork block 3 with the remaining formwork block connector 1. 5B is a plan view further including the turnbuckle 10 in FIG. 5A.
Moreover, FIG. 6A is a top view which shows the state which connected the quay 2 and the residual form block 3 with the connection metal fitting 1 for residual form blocks, and FIG. 6B is the side view.

岸壁の補修は、破損した岸壁の前方に残置型枠ブロックを設置し積み上げ、積み上げた残置型枠ブロックと岸壁との間に水中コンクリートを打設して新たな岸壁を構築して行う。このとき、岸壁の前方に積み上げた残置型枠ブロックの倒壊を防止するために、水中コンクリートの打設の前に、予め残置型枠ブロック用接続金具を岸壁と残置型枠ブロックに取り付けて、これらを接続しておく。   The repair of the wharf will be carried out by placing the remaining formwork blocks in front of the damaged wharf and stacking them, placing underwater concrete between the stacked remaining formwork blocks and the wharf to construct a new wharf. At this time, in order to prevent the collapse of the residual formwork blocks stacked in front of the quay, the connection metal fittings for the residual formwork blocks are attached to the quay and the residual formwork blocks in advance before placing the underwater concrete. Keep connected.

次に、残置型枠ブロック用接続金具１を岸壁２と残置型枠ブロック３へ接続する場合を説明する。
まず、第一回転体１１をアンカー鉄筋２４により予め岸壁に取り付けておく。他方、第二回転体１２は、水中へ投入する前の残置型枠ブロック３に連結鉄筋３３を螺合して取り付けておく。つまり、残置型枠ブロック３は、第二回転体１２が取り付けられた状態で水中に投入して設置する。次に、水中においてターンバックル１０で第一回転体１１と第二回転体１２を連結して取り付ける。この場合、岸壁２に取り付けられた第一回転体１１のアンカー鉄筋２４は、第一回転体１１と第二回転体１２とを連結して取り付けできるように予め適合する長さのものが選択されているが、実際には残置型枠ブロック３を水中に投入設置した場合の施工誤差による位置ズレにより、両者が連結して取り付けられない場合が生じる。そこで、本実施形態では、その場合に、残置型枠ブロック用接続金具１のターンバック１０の長さと、水平面内及び水平面内における角度を調整することで、第一回転体１１及び第二回転体１２を連結して取り付ける。 Next, the case where the connection fitting 1 for residual form block is connected to the quay 2 and the residual form block 3 will be described.
First, the first rotating body 11 is attached to the quay in advance by the anchors 24. On the other hand, the connecting rod 33 is screwed and attached to the residual form block 3 before the second rotary body 12 is put into water. That is, the remaining mold block 3 is placed in the water and installed in a state where the second rotary body 12 is attached. Next, the first rotating body 11 and the second rotating body 12 are connected and attached with the turnbuckle 10 in water. In this case, anchor rebars 24 of the first rotating body 11 attached to the wharf 2 are selected to have a length that fits in advance so that the first rotating body 11 and the second rotating body 12 can be connected and attached. However, in practice, due to a positional deviation due to a construction error when the residual mold block 3 is placed in water, the case where both can not be connected and attached may occur. Therefore, in the present embodiment, in this case, the first rotary body 11 and the second rotary body are adjusted by adjusting the length of the turnback 10 of the connection fitting 1 for residual form block and the horizontal plane and the horizontal plane. Connect 12 and attach.

なお、ターンバックル１０での伸縮による長さの調整は微調整であって、岸壁２と残置型枠ブロック３間の距離に応じた残置型枠ブロック用接続金具１全体の長さの調整は、上述のように長さの異なる複数のアンカー鉄筋２４の中から最適な長さのものを選択することによって調整する。   The adjustment of the length by expansion and contraction with the turnbuckle 10 is a fine adjustment, and the adjustment of the entire length of the connection fitting 1 for the remaining form block according to the distance between the quay 2 and the remaining form block 3 is As described above, adjustment is made by selecting an optimal length from a plurality of anchor bars 24 of different lengths.

次に、残置型枠ブロック用接続金具１の調整について説明する。まず、岸壁２と残置型枠ブロック３において施工誤差による位置ズレが水平面内で発生した場合を例にとって説明する。なお、図５Ａ、図５Ｂでは、この水平面内で発生した位置ズレを上下方向で示している。なお、図示例は水平面内の位置ズレを示しているが、位置ズレはそれと直交する面内においても生じる。   Next, adjustment of the residual mold block connection fitting 1 will be described. First, the case where positional deviation due to construction error occurs in the quay 2 and the residual form block 3 in the horizontal plane will be described as an example. In FIG. 5A and FIG. 5B, the positional deviation generated in the horizontal plane is shown in the vertical direction. Although the illustrated example shows the positional deviation in the horizontal plane, the positional deviation also occurs in the plane orthogonal to that.

ここでは、まず水平面内の位置ズレについて説明する。図５Ａは、第一回転体１１を取り付けた岸壁２と第二回転体１２を取り付けて水中に投入設置された残置型枠ブロック３の位置関係を示している。
この状態において、図５Ｂに示すように、ターンバックル１０を用意する。このターンバックル１０を岸壁２に取り付けた第一回転体１１と残置型枠ブロック３に取り付けた第二回転体１２とにわたって取り付ける。即ち、第一回転体１１の回転部材２５とターンバックル１０の第一部材１４とを重ね合わせて、それぞれに設けたボルト挿通孔２９，１９にボルト３１を挿通して、ターンバックル１０に第一回転体１１を回転自在に取り付ける。また、第二回転体１２の回転部材３４とターンバックル１０の第二部材１５とを重ね合わせて、それぞれに設けたボルト挿通孔３７，２３にボルト３１を挿通して、ターンバックル１０に第二回転体１２を回転自在に取り付ける。 Here, first, positional deviation in the horizontal plane will be described. FIG. 5A shows the positional relationship between the quayment 2 to which the first rotating body 11 is attached and the residual mold block 3 attached to the second rotating body 12 and inserted into the water.
In this state, as shown in FIG. 5B, the turnbuckle 10 is prepared. The turnbuckle 10 is attached over the first rotating body 11 attached to the quay 2 and the second rotating body 12 attached to the residual form block 3. That is, the rotating member 25 of the first rotating body 11 and the first member 14 of the turnbuckle 10 are overlapped, and the bolt 31 is inserted into the bolt insertion holes 29 and 19 provided in each of them. The rotating body 11 is rotatably mounted. Further, the rotating member 34 of the second rotating body 12 and the second member 15 of the turnbuckle 10 are overlapped, and the bolt 31 is inserted into the bolt insertion holes 37 and 23 provided in each of them. The rotating body 12 is rotatably mounted.

ここで、ターンバックル１０を第一回転体１１と第二回転体１２に取り付けるため、予め第一回転体１１の回転部材２５とターンバックル１０の第一部材１４に設けたボルト挿通孔２９，１９、及び第二回転体１２の回転部材３４とターンバックル１０の第二部材１５に設けたボルト挿通孔３７，２３の位置が一致するよう、ターンバックル１０の長さを調整しておく。   Here, in order to attach the turnbuckle 10 to the first rotating body 11 and the second rotating body 12, bolt insertion holes 29 and 19 provided in advance in the rotating member 25 of the first rotating body 11 and the first member 14 of the turnbuckle 10. The length of the turnbuckle 10 is adjusted so that the positions of the bolt insertion holes 37 and 23 provided in the rotating member 34 of the second rotating body 12 and the second member 15 of the turnbuckle 10 coincide with each other.

具体的には、回転用レバー１６を用いて軸部材１３を回転してターンバックル１０の第一部材１４と第二部材１５が互いに近づいたり離れたりすることで、その全長を伸縮させて長さを微調整する。
それとともに、ターンバックル１０と第一回転体１１について、第一回転体１１を、ターンバックル１０に対してボルト挿通孔１９，２９に挿通したボルト３１を中心にして調整された回転位置（任意の回転位置）になるように、ターンバックル１０と第一回転体１１の回転角度を調整する。
また、ターンバックル１０と第二回転体１２についても、第二回転体１２を、ターンバックル１０に対してボルト挿通孔２３，３７に挿通したボルト３１を中心にして調整された回転位置（任意の回転位置）になるように、ターンバックル１０と第二回転体１２の回転角度を調整する。 Specifically, by rotating the shaft member 13 using the rotation lever 16 to move the first member 14 and the second member 15 of the turnbuckle 10 closer to or away from each other, the entire length is extended or reduced to make the length Fine-tune the
At the same time, the rotational position of the turnbuckle 10 and the first rotary body 11 is adjusted about the bolt 31 inserted through the bolt insertion holes 19 and 29 with respect to the turnbuckle 10 (arbitrary rotational position (arbitrary The rotation angles of the turnbuckle 10 and the first rotating body 11 are adjusted so as to be the rotation position).
Further, with regard to the turnbuckle 10 and the second rotary body 12 as well, the rotational position (arbitrary rotational position adjusted about the bolt 31 having the second rotary body 12 inserted into the bolt insertion holes 23 and 37 with respect to the turnbuckle 10) The rotation angle of the turnbuckle 10 and the second rotary body 12 is adjusted so as to be the rotational position).

このようにして残置型枠ブロック用接続金具１の調整を行った後、図６Ａ、図６Ｂに示すように、第一回転体１１の回転部材２５とターンバックル１０の第一部材１４に挿通したボルト３１をナット３２で締結し、第一回転体１１をターンバックル１０に調整された回転位置で固定する。同様に、第二回転体１２の回転部材３４とターンバックル１０の第二部材１５に挿通したボルト３１をナット３２で締結し、第二回転体１２をターンバックル１０に調整された回転位置で固定する。
これにより、残置型枠ブロック用接続金具１を岸壁２と残置型枠ブロック３に取り付けて、岸壁２と残置型枠ブロック３を接続することができる。 Thus, after adjusting the connection fitting 1 for residual form block, as shown to FIG. 6A and FIG. 6B, it penetrated to the rotation member 25 of the 1st rotary body 11, and the 1st member 14 of the turnbuckle 10. The bolt 31 is fastened by the nut 32, and the first rotating body 11 is fixed to the turnbuckle 10 at the adjusted rotational position. Similarly, the bolt 31 inserted into the rotating member 34 of the second rotating body 12 and the second member 15 of the turnbuckle 10 is fastened with the nut 32 and fixed to the turnbuckle 10 at the rotational position adjusted to the second rotating body 12. Do.
Thereby, the connection fitting 1 for residual form block can be attached to the quay 2 and the residual form block 3, and the quay 2 and the residual form block 3 can be connected.

次に、岸壁２と残置型枠ブロック３において施工誤差による位置ズレが水平面内だけでなく垂直面内にも発生した場合（即ち、斜め方向に発生した場合）の残置型枠ブロック用接続金具１の岸壁２及び残置型枠ブロック３への取り付けをより詳細に説明する。
基本的には、施工誤差による位置ズレが水平面内で発生した場合と同じであるが、ターンバックル１０の第一部材１４及び第二部材１５での旋回、第一回転体１１の回転部材２５での旋回、第二回転体１２の回転部材３４での旋回を行うことで、それぞれの旋回角度を調整する。 Next, in the case where displacement due to construction error occurs not only in the horizontal plane but also in the vertical plane in the quay 2 and the residual formwork block 3 (that is, when generated in an oblique direction) The attachment to the quay 2 and the residual formwork block 3 will be described in more detail.
Basically, the positional deviation due to construction error is the same as in the case where it occurs in the horizontal plane, but the turning of the first member 14 and the second member 15 of the turnbuckle 10, the rotating member 25 of the first rotating body 11 The turning angle of the second rotating body 12 is adjusted by performing the turning of the second rotary body 12 with the turning member 34.

具体的には、岸壁２に第一回転体１１に取り付けたアンカー鉄筋２４を埋め込んで取り付けた後、第一回転体１１の回転部材２５をアンカー鉄筋２４を中心に旋回させて、回転部材２５の向きを位置ズレしている斜めの方向と同じ方向にする（第一回転体１１の旋回角度を調整する）。それとともに、第二回転体１２の連結鉄筋３３を残置型枠ブロック３に螺合して取り付け、第二回転体１２の回転部材３４を残置型枠ブロック３に対して連結鉄筋３３とともにも旋回させて、回転部材２５の向きを位置ズレしている斜めの方向と同じ方向にする（第二回転体１２の旋回角度を調整する）。   Specifically, after the anchor rebar 24 attached to the first rotating body 11 is embedded and attached to the quay 2, the rotating member 25 of the first rotating body 11 is pivoted about the anchor rebar 24 so that the rotating member 25 is The direction is the same as the misaligned oblique direction (the turning angle of the first rotating body 11 is adjusted). At the same time, the connecting rebar 33 of the second rotating body 12 is screwed on and attached to the remaining form block 3 and the rotating member 34 of the second rotating body 12 is pivoted together with the connecting rebar 33 with respect to the remaining form block 3 And the direction of the rotation member 25 is the same as the oblique direction in which the position is shifted (the turning angle of the second rotation body 12 is adjusted).

次に、岸壁２に取り付けた第一回転体１１と残置型枠ブロック３に取り付けた第二回転体１２にターンバックル１０を取り付ける。このとき、ターンバックル１０では、その長さを調整しておくとともに、第一部材１４及び第二部材１５を旋回させて、第一部材１４及び第二部材１５の向きを位置ズレしている斜めの方向と同じ方向にする（ターンバックル１０の第一部材１４及び第二部材１５の旋回角度を調整する）。
即ち、ターンバックル１０の第一部材１４及び第二部材１５、第一回転体１１の回転部材２５、第二回転体１２の回転部材３４の向きが、すべて一致するよう、それぞれの旋回角度を調整する。 Next, the turnbuckle 10 is attached to the first rotating body 11 attached to the quay 2 and the second rotating body 12 attached to the residual form block 3. At this time, in the turnbuckle 10, while adjusting its length, the first member 14 and the second member 15 are pivoted to obliquely shift the directions of the first member 14 and the second member 15 In the same direction as the direction of (adjust the pivot angle of the first member 14 and the second member 15 of the turnbuckle 10).
That is, the respective turning angles are adjusted so that the directions of the first member 14 and the second member 15 of the turnbuckle 10, the rotating member 25 of the first rotating body 11, and the rotating member 34 of the second rotating body 12 all coincide. Do.

このようにして残置型枠ブロック用接続金具１の調整を行った後、第一回転体１１をターンバックル１０に調整された回転位置（任意の回転位置）で固定するとともに、第二回転体１２をターンバックル１０に調整された回転位置（任意の回転位置）で固定する。固定は、上述の水平面内の位置ズレの場合と同様に、ボルト３１をナット３２で締結して行う。
これにより、岸壁２と残置型枠ブロック３において施工誤差による位置ズレが斜め方向に発生した場合でも、残置型枠ブロック用接続金具１を岸壁２と残置型枠ブロック３に取り付けて、これらを接続することができる。 Thus, after adjusting the connection fitting 1 for residual form block, the first rotary body 11 is fixed to the turn buckle 10 at the adjusted rotational position (arbitrary rotational position), and the second rotary body 12 Is fixed to the turnbuckle 10 at the adjusted rotational position (arbitrary rotational position). The fixing is performed by fastening the bolt 31 with the nut 32 as in the case of the positional deviation in the horizontal plane described above.
Thereby, even if positional deviation due to construction error occurs in the quay 2 and the residual formwork block 3 in the oblique direction, the residual formwork block connector fitting 1 is attached to the quay 2 and the residual formwork block 3 and these are connected can do.

図７は、調整後の残置型枠ブロック用接続金具を説明する斜視図である。
残置型枠ブロック用接続金具１は、図示のように、岸壁２に付けるアンカー鉄筋２４と残置型枠ブロック３に付ける連結鉄筋３３の位置及び方向に合わせて、残置型枠ブロック用接続金具１の位置（長さの微調整を含む）、方向、回転角度及び旋回角度を調整することにより、岸壁２とその前方に設置する残置型枠ブロック３での様々な状況（岸壁２と残置型枠ブロック３の間の距離及び位置ズレ）に対応させて、岸壁２と残置型枠ブロック３を接続することができる。 FIG. 7 is a perspective view for explaining the connection fitting for the remaining mold block after adjustment.
As shown in the figure, the connection bracket 1 for the remaining form block is made of the connection fitting 1 for the remaining form block according to the positions and directions of the anchor bars 24 attached to the quay 2 and the connecting rebars 33 attached to the remaining form block 3. By adjusting the position (including the fine adjustment of the length), the direction, the rotation angle and the turning angle, various situations in the berth 2 and the remaining form block 3 installed in front thereof (the quay 2 and the remaining form block The quay 2 and the residual form block 3 can be connected in correspondence with the distance and positional deviation between 3).

以上説明したように、本実施形態の残置型枠ブロック用接続金具１によれば、岸壁２の補修において、岸壁２とその前方に設置した残置型枠ブロック３とを接続する際に、岸壁２と残置型枠ブロック３において施工誤差による位置ズレが発生しても、ターンバックル１０の長さの調整、ターンバックル１０と第一回転体１１及び第二回転体１２との回転角度の調整、ターンバックル１０の第一部材１４及び第二部材１５の旋回角度の調整、第一回転体１１及び第二回転体１２の旋回角度の調整を行うことで、残置型枠ブロック用接続金具１により、岸壁２と残置型枠ブロック３を確実に接続することができる。   As explained above, according to the connection bracket 1 for residual formwork block of the present embodiment, when repairing the quay 2, when connecting the quay 2 and the residual formwork block 3 installed in front thereof, the quay 2 Even if positional deviation occurs due to construction errors in the residual form block 3, adjustment of the length of the turnbuckle 10, adjustment of the rotation angle between the turnbuckle 10 and the first rotating body 11 and the second rotating body 12, turn By adjusting the turning angle of the first member 14 and the second member 15 of the buckle 10 and adjusting the turning angle of the first rotating body 11 and the second rotating body 12, the quaywall is formed by the connection fitting 1 for residual form frame block 2 and the remaining mold block 3 can be securely connected.

また、残置型枠ブロック用接続金具１により岸壁２と残置型枠ブロック３とを接続した後、締結手段（ボルト３１とナット３２）で、ターンバックル１０に第一回転体１１と第二回転体１２をそれぞれ固定することで、岸壁２と残置型枠ブロック３を強固に連結することができる。
このように、本実施形態によれば、従来のような溶接による作業をなくすことで、その作業性の向上を図ることができる。しかも、これらの作業を水中で行っても、作業が簡単であるから、容易に行うことができ、作業時間の短縮を図ることができる。 In addition, after connecting the quay 2 and the residual form block 3 by the residual form block connecting fitting 1, the first rotating body 11 and the second rotating body are formed on the turn buckle 10 by the fastening means (the bolt 31 and the nut 32). By fixing 12 respectively, the quay 2 and the residual form block 3 can be firmly connected.
Thus, according to the present embodiment, the workability can be improved by eliminating the conventional welding operation. In addition, even if these operations are performed in water, the operations are easy, so they can be easily performed, and the operation time can be shortened.

次に、本発明の残置型枠ブロック用接続金具の第二の実施形態について説明する。
図８は、第二の実施形態の残置型枠ブロック用接続金具の斜視図である。
残置型枠ブロック用接続金具１は、前述の実施形態の残置型枠ブロック用接続金具１と基本的な構成は同じであるが、図示のように、ターンバックル１０の第一部材１４及び第二部材１５と六角パイプ部１８，２２の接合、第一回転体１１の回転部材２５と六角パイプ部２８の接合、第二回転体１２の回転部材３４と連結鉄筋３３の接合において異なるので、ここについてのみ説明する。なお、符号は、前述の実施形態で説明したのと同じである。 Next, a second embodiment of the connection fitting for residual mold block of the present invention will be described.
FIG. 8 is a perspective view of the connection fitting for the remaining mold block of the second embodiment.
The remaining formwork block connection fitting 1 has the same basic configuration as the remaining formwork block connection fitting 1 of the above-described embodiment, but as illustrated, the first member 14 and the second member of the turnbuckle 10 are used. Because the joint of the member 15 and the hexagonal pipe portions 18 and 22, the joint of the rotary member 25 of the first rotary body 11 and the hexagonal pipe portion 28, and the joint of the rotary member 34 of the second rotary body 12 and the connecting rebar 33 differ, Only explain. The reference numerals are the same as those described in the above embodiment.

ターンバックル１０は、第一部材１４のプレート部１７の上面に六角パイプ部１８の下端部が溶着や接着などの適宜手段、例えば溶接又は接着剤により接合されるとともに、第二部材１５のプレート部２１の上面に六角パイプ部２２の下端部が、例えば溶接又は接着剤により接合されている。また、第一回転体１１は、回転部材２５のプレート部２７の上面に六角パイプ部２８の下端部が、例えば溶接又は接着剤により接合されている。また、第二回転体１２は、回転部材３４のプレート部３６の上面に連結鉄筋３３の下端部が、例えば溶接又は接着剤により接合されている。   The lower end portion of the hexagonal pipe portion 18 is joined to the upper surface of the plate portion 17 of the first member 14 by an appropriate means such as welding or adhesion, for example, welding or an adhesive. The lower end portion of the hexagonal pipe portion 22 is joined to the upper surface of the joint 21, for example, by welding or an adhesive. The lower end portion of the hexagonal pipe portion 28 is joined to the upper surface of the plate portion 27 of the rotation member 25 by, for example, welding or an adhesive. Further, the lower end portion of the connection reinforcing bar 33 is joined to the upper surface of the plate portion 36 of the rotating member 34 by, for example, welding or an adhesive in the second rotating body 12.

このように、ターンバックル１０の第一部材１４及び第二部材１５と六角パイプ部１８，２２の接合、第一回転体１１の回転部材２５と六角パイプ部２８の接合、第二回転体１２の回転部材３４と連結鉄筋３３の接合が、第一の実施形態におけるようにそれぞれ六角パイプ部の断面の上下中央部ではなく、六角パイプ部の下端部において溶接又は接着剤で行うことで、これらの部品を極めて容易に製作することができ、これにより、残置型枠ブロック用接続金具１を安価なものにすることができる。
なお、第二の実施形態においても、第一の実施形態と同様に、岸壁２と残置型枠ブロック３の間の距離及び位置ズレに対して容易に対応して、両者を強固に連結することができる。 Thus, the first member 14 and the second member 15 of the turnbuckle 10 and the hexagonal pipe portions 18 and 22 are joined, the rotational member 25 of the first rotary body 11 and the hexagonal pipe portion 28 are joined, and the second The joint of the rotating member 34 and the connecting rebar 33 is performed by welding or an adhesive at the lower end of the hexagonal pipe, not at the upper and lower center of the cross section of the hexagonal pipe as in the first embodiment.
