Description

本発明は、コンクリート岸壁に用いる残存型枠とこれを用いたコンクリート岸壁の構築方法に関する。   The present invention relates to a residual mold used for a concrete quay and a method for constructing a concrete quay using the same.

本発明において、例えば4段に積層された残存型枠は、下から順に最下段の残存型枠、下中段の残存型枠、上中段の残存型枠、そして最上段の残存型枠とし、ある残存型枠の上又は下に積層された残存型枠指す場合、上層段の残存型枠又は下層段の残存型枠と呼ぶ。例えば前述のように、残存型枠が4段に積層された場合、最上段の残存型枠に対して下層段の残存型枠は上中段の残存型枠であり、前記上中段の残存型枠は下中段の残存型枠に対して上層段の残存型枠となる。   In the present invention, for example, the remaining molds stacked in four stages are, in order from the bottom, the lowermost remaining mold, the lower middle remaining mold, the upper middle remaining mold, and the uppermost remaining mold. When referring to a residual mold laminated on or below the residual mold, it is called an upper-layer residual mold or a lower-layer residual mold. For example, as described above, when the remaining molds are stacked in four levels, the lower level residual molds are the upper middle level residual molds with respect to the uppermost level residual molds, and the upper middle level residual molds. Is an upper-layer residual mold with respect to the lower-middle residual mold.

港湾等の陸上端を形成するコンクリート岸壁は、金属製の型枠を現況岸壁に対して並べ、前記型枠と現況岸壁(地盤がむき出し又はセメントミルクを吹き付けただけの岸壁)との間にコンクリートを打設した後、前記型枠を回収して構築される。近年、型枠の回収に掛かる工数を低減するため、打設したコンクリートと共にコンクリート岸壁を構成するコンクリート製の残存型枠が使用されることもある(特許文献1)。   The concrete quay that forms the land edge of a port, etc., has a metal formwork aligned with the existing quay, and the concrete is placed between the formwork and the existing quay (the quay where the ground is exposed or cement milk is just sprayed). After the placement, the mold is collected and constructed. In recent years, in order to reduce the number of man-hours required for collecting the formwork, a concrete residual formwork that forms the concrete quay with the cast concrete may be used (Patent Document 1).

特許文献1が開示する岸壁の構築方法は、中空枠状であるコンクリート製の残存型枠(中空ブロック)を予め重ねて結合して積層型枠とし、施工場所に設置した前記積層型枠にコンクリート(水中コンクリート)を打設して、残存型枠を含めた岸壁を構築する(特許文献1・[請求項1]ほか)。特許文献1は、残存型枠の設置に要する時間を短縮し、コンクリート岸壁の構築に要する施工期間を短縮する(特許文献1・[0041]ほか)。   The construction method of a quay disclosed in Patent Document 1 is a method in which a concrete residual mold (hollow block) made of a hollow frame is overlapped in advance to form a laminated mold, and concrete is applied to the laminated mold installed at a construction site. (Underwater concrete) is placed to construct a quay including the remaining formwork (Patent Document 1, [Claim 1] and others). Patent Document 1 shortens the time required to install the remaining formwork and shortens the construction period required to construct the concrete quay (Patent Document 1, [0041], etc.).

特開平11-229411号公報Japanese Patent Laid-Open No. 11-229411

コンクリート岸壁は、経年劣化のほか、自然災害等により破損することがある。一部が破損したコンクリート岸壁は、壊れた箇所を除去した後、新たにコンクリートを打設し、補修される。こうした補修作業に際しても型枠が使用されるため、上述同様、回収をしない残存型枠が好まれる。これから、コンクリート岸壁の補修に際して、例えば特許文献1が開示する残存型枠を利用することが考えられる。   The concrete quay may be damaged by natural disasters as well as deterioration over time. The partially damaged concrete quay will be repaired by removing the broken part and then placing new concrete. Since the formwork is also used for such repair work, the remaining formwork that is not collected is preferred as described above. From this, it is conceivable to use, for example, the remaining form disclosed in Patent Document 1 when repairing a concrete quay.

コンクリート岸壁を補修する場合、新設の場合と異なり、施工現場の制約が多いため、残存型枠を設置する設置面を水平に整えることが難しい。そうであるにも拘らず、補修作業の場合、残存型枠の前面を、施工計画に沿ったコンクリート岸壁の前面に一致させなければならず、設置面が水平でなければ、積層される残存型枠が上層段になるほど傾きが大きくなるため、残存型枠個々の姿勢を調整する必要性が高い。このため、姿勢について言及のない特許文献1記載の残存型枠をコンクリート岸壁の補修に使用するには、新たに姿勢調整手段を検討しなければならない。   When repairing a concrete quay, unlike the case of a new construction, there are many restrictions at the construction site, so it is difficult to level the installation surface on which the remaining formwork is installed. Despite this, in the case of repair work, the front of the remaining formwork must match the front of the concrete quay according to the construction plan. Since the inclination becomes larger as the frame becomes the upper layer, it is highly necessary to adjust the posture of each remaining mold. For this reason, in order to use the remaining formwork described in Patent Document 1 that does not mention the posture for repairing the concrete quay, a new posture adjusting means must be considered.

そこで、施工現場の制約が多いため、設置面を水平に整えることが難しいコンクリート岸壁の補修作業において、設置面に載せる最下段の残存型枠に対して積層していく上層
段の残存型枠の姿勢を個々に調整できるように、残存型枠に新たな姿勢調整手段を設けると共に、前記残存型枠の姿勢調整を補助する手段や、前記残存型枠を姿勢調整することにより新たに必要となる手段について、検討した。
Therefore, because there are many restrictions at the construction site, in the repair work of concrete quay where it is difficult to level the installation surface, the upper form of the remaining formwork that is stacked on the bottom form of the lower form placed on the installation surface In order to be able to adjust the posture individually, a new posture adjusting means is provided in the remaining mold, and it is newly required by adjusting the posture of the remaining mold and a means for assisting the posture adjustment of the remaining mold The means were examined.

検討の結果開発したものが、岸壁前面を形成する主壁と、前記主壁の左端又は右端に設けた扶壁とから構成されるコンクリートブロックで、主壁は、上方への突出量が調整自在な高さ調整ボルトを、左右に離れた位置で上面の2ヶ所に設け、扶壁は、前記高さ調整ボルトを、前記主壁の上面に設けた高さ調整ボルトを結ぶ直線より後方で上面の1ヶ所に設けてなる残存型枠である。本発明において、コンクリート岸壁の海側を前側、陸側を後側として主壁の前面及び後面を定義し、また陸側(後側)に向かって主壁の左右及び上下を定義し、前記主壁の前面に連続する扶壁の側面を外側面、前記主壁の後面に連続する扶壁の側面を内側面とする。   The result of the study was a concrete block composed of a main wall that forms the front of the quay and a dredging wall provided at the left or right end of the main wall. The main wall has an adjustable amount of upward protrusion. Height adjustment bolts are provided at two positions on the upper surface at positions separated from each other on the left and right, and the eaves wall is disposed on the upper surface behind the straight line connecting the height adjustment bolts provided on the upper surface of the main wall. It is the residual formwork provided in one place. In the present invention, the front and rear surfaces of the main wall are defined with the sea side of the concrete quay as the front side and the land side as the rear side, and the left and right and upper and lower sides of the main wall are defined toward the land side (rear side). The side surface of the wall that is continuous with the front surface of the wall is the outer surface, and the side surface of the wall that is continuous with the rear surface of the main wall is the inner surface.

本発明の残存型枠は、例えば平面視コ字状のコンクリートブロックを左右中心で半割し、主壁の左端又は右端から折れ曲がって扶壁が後方に延びる平面視L字状のコンクリートブロックであり、左端及び右端それぞれに扶壁を有する左右対称な2基を一組として平面視コ字状の単位壁面を構成する。コンクリート岸壁の延在長さに合わせて前記単位壁面を複数並べる場合、隣り合う単位壁面の扶壁を直接接面させたり、目地材を介装して連結させたりする。   The residual form of the present invention is an L-shaped concrete block in plan view, for example, in which a U-shaped concrete block in plan view is divided in half at the left and right centers and bent from the left end or right end of the main wall so that the eaves wall extends rearward. A unit wall surface having a U-shape in a plan view is formed of a pair of two symmetrical left and right symmetric walls having a wall at each of the left end and the right end. When arranging a plurality of the unit wall surfaces according to the extension length of the concrete quay wall, the adjacent wall surfaces of the unit wall surfaces are directly brought into contact with each other or connected with joint materials.

下層段の残存型枠の主壁の上面に設けた2ヶ所の高さ調整ボルトと、扶壁の上面に設けた1ヶ所の高さ調整ボルトとは、上層段の残存型枠を三点支持する。上層段の残存型枠は、前記3ヶ所の高さ調整ボルトに囲まれた範囲に重心を有するため、よほど傾斜のきつい姿勢とならない限り、下層段の残存型枠から滑り落ちる虞がない。また、3ヶ所の高さ調整ボルトは、4ヶ所以上に高さ調整ボルトを設けた場合と異なり、必ずすべての高さ調整ボルトが上層段の残存型枠を支持するため、がたつきを抑制又は防止できる。   The two height adjustment bolts provided on the upper surface of the main wall of the lower-stage residual formwork and the one height adjustment bolt provided on the upper surface of the eaves wall support the upper-stage residual formwork at three points. To do. Since the remaining mold in the upper layer has a center of gravity in a range surrounded by the three height adjusting bolts, there is no possibility of slipping off the remaining mold in the lower layer unless the inclination is very steep. In addition, unlike the case where the height adjustment bolts are installed at four or more locations, the height adjustment bolts at the three locations always support the remaining formwork of the upper layer to suppress rattling. Or it can be prevented.

こうして、本発明の残存型枠を用いれば、現況岸壁直前の海底に設置面を形成し、コンクリートブロックである残存型枠を前記設置面上に積層し、積層された残存型枠と現況岸壁との間にコンクリートを打設して、前記残存型枠とコンクリートとが一体となったコンクリート岸壁を構築するに際し、扶壁を現況岸壁に向けて積層する残存型枠は、下層段の残存型枠の高さ調整ボルトそれぞれの突出量を加減し、上層段の残存型枠の下面を前記高さ調整ボルトに支持させることにより、下層段の残存型枠に対して上層段の残存型枠の姿勢を調整する手順でコンクリート岸壁を構築する。最上段の残存型枠は、更に残存型枠を積層しないため、高さ調整ボルトを省略できるように、前記高さ調整ボルトを着脱自在にするとよい。   Thus, if the remaining formwork of the present invention is used, an installation surface is formed on the sea floor immediately before the existing quay, and the remaining formwork, which is a concrete block, is laminated on the installation surface, and the stacked remaining formwork and the existing quay When constructing a concrete quay where the residual formwork and the concrete are integrated by placing concrete between the remaining formwork, the residual formwork that laminates the dredging wall toward the existing quay is the remaining formwork of the lower level. By adjusting the amount of protrusion of each of the height adjustment bolts and supporting the lower surface of the upper-layer residual mold form on the height adjustment bolt, the attitude of the upper-stage residual mold form relative to the lower-stage residual mold form Build a concrete quay with the procedure to adjust. Since the uppermost remaining formwork does not further stack the remaining formwork, the height adjustment bolt is preferably detachable so that the height adjustment bolt can be omitted.

本発明の残存型枠は、左右に延在する凸段差を主壁の上面に設け、前記凸段差と転写関係にある凹段差を左右に延在させて前記主壁の下面に設けることにより、上層段の残存型枠の下面に設けた凹段差と、下層段の残存型枠の上面に設けた凸段差とを密着又は両者の隙間を蛇行させて、積層された残存型枠と現況岸壁との間に打設するコンクリートが、下層段の残存型枠と上層段の残存型枠との間から漏れることを防止する。「隙間を蛇行させる」とは、対向する凸段差及び凹段差間に形成される隙間が、縦断面形状において折れ曲っていることを意味する。凸段差及び凹段差は、一方が凸ならば他方が凹であるような転写関係にある部位で、単なる高低差のある平面の境界のほか、前記高低差を前後に有する凸条及び凹溝を含む。最上段の残存型枠は、更に残存型枠を積層しないため、上面の凸段差を省略し、最下段の残存型枠は、下面が設置面に接面するため、前記下面の凹段差を省略して構成できる。   The remaining mold of the present invention is provided with a convex step extending in the left and right on the upper surface of the main wall, and by providing a concave step in transfer relation with the convex step in the left and right on the lower surface of the main wall, Adhering the concave step provided on the lower surface of the upper mold of the upper layer and the convex step provided on the upper surface of the lower mold of the lower layer or meandering the gap between the two, the stacked residual mold and the existing quay The concrete placed between the upper and lower layers is prevented from leaking between the remaining molds of the lower layer and the upper layer. “Meandering the gap” means that the convex step and the gap formed between the concave steps facing each other are bent in the longitudinal cross-sectional shape. A convex step and a concave step are portions that are in a transfer relationship in which one is convex and the other is concave.In addition to a plane boundary having a simple height difference, a convex line and a groove having the height difference in the front and rear are provided. Including. Since the uppermost remaining formwork does not further laminate the remaining formwork, the convex step on the upper surface is omitted, and the lowermost residual formwork omits the concave step on the lower surface because the lower surface is in contact with the installation surface. Can be configured.

また、本発明の残存型枠は、高さ調整ボルトの最大突出量より長い連結ピンを主壁又は扶壁の上面から上方に突出し、前記連結ピンを挿入させる連結穴を下面に設けることにより、上層段の残存型枠の下面に設けた連結穴に、下層段の残存型枠の上面に設けた連結ピンを挿入させ、積層された残存型枠の前後及び左右の水平位置を一致させ、下層段の残存型枠に対する上層段の残存型枠の位置関係を特定し、上層段の残存型枠が下層段の残存型枠から脱落することを防止する。   Further, the remaining mold according to the present invention projects a connecting pin longer than the maximum protruding amount of the height adjustment bolt from the upper surface of the main wall or the wall, and provides a connecting hole for inserting the connecting pin on the lower surface. Insert the connecting pin provided on the upper surface of the lower form residual mold into the connection hole provided on the lower face of the upper residual mold, and align the horizontal positions of the stacked residual mold in the front and rear and left and right sides. The positional relationship of the upper-layer remaining formwork with respect to the remaining-stage formwork is specified, and the upper-stage remaining formwork is prevented from falling off the lower-stage remaining formwork.

連結ピンは、主壁又は扶壁の上面から突出させて前記主壁又は扶壁と一体に構成してもよいし、別体として主壁又は扶壁に着脱自在としてもよい。連結ピン及び連結穴の組み合わせは、高さ調整ボルトによる上層段の残存型枠の姿勢調整を妨げないように、主壁及び扶壁の交点に1組設けることが好ましい。最上段の残存型枠は、更に残存型枠を積層しないため、上面の連結ピンを省略できるように、前記連結ピンは着脱自在にするとよい。また、最下段の残存型枠は、下面が設置面に接面するため、前記下面の連結穴を省略してもよいし、あっても邪魔にならない。   The connecting pin may protrude from the upper surface of the main wall or the eaves wall and may be configured integrally with the main wall or the eaves wall, or may be detachable from the main wall or the eaves wall as a separate body. It is preferable that a combination of the connecting pin and the connecting hole is provided at an intersection of the main wall and the wall so as not to hinder the posture adjustment of the upper-layer remaining formwork by the height adjusting bolt. Since the uppermost remaining formwork does not further stack the remaining formwork, the connecting pin is preferably detachable so that the upper connecting pin can be omitted. Further, since the bottom surface of the remaining formwork is in contact with the installation surface, the connecting hole on the lower surface may be omitted or not present.

更に、本発明の残存型枠は、上面から上方に突出する設置ガイドを着脱自在に主壁の後面に設け、上層段の残存型枠の後面を、下層段の残存型枠の上面から上方に突出させた設置ガイドに宛てがうことにより、前記上層段の残存型枠が前記下層段の残存型枠に対して後方へ逸脱することを防止する。設置ガイドは、残存するコンクリート岸壁の前面と主壁の前面とを一致させるために後方へ押し込む残存型枠の過度な後方への移動を防止する。連結ピン及び連結穴の組み合わせと併用すれば、下層段の残存型枠に対する上層段の残存型枠の水平位置をより容易に特定できる。設置ガイドは、残存型枠に残して打設するコンクリートに埋め殺してもよいが、基本的には残存型枠の積層を終えれば不要になるため、着脱自在とし、前記積層を終えた後に取り外せるようにするとよい。   Furthermore, in the remaining mold of the present invention, an installation guide that protrudes upward from the upper surface is detachably provided on the rear surface of the main wall, and the rear surface of the upper-layer residual mold is directed upward from the upper surface of the lower-layer residual mold. By being directed to the protruding installation guide, it is possible to prevent the remaining mold of the upper layer from deviating backward with respect to the remaining mold of the lower layer. The installation guide prevents excessive rearward movement of the remaining formwork that is pushed backward to align the front of the remaining concrete quay with the front of the main wall. If it is used in combination with a combination of a connecting pin and a connecting hole, the horizontal position of the remaining mold in the upper layer relative to the remaining mold in the lower layer can be more easily specified. The installation guide may be buried in the concrete to be cast while remaining in the remaining formwork, but basically it becomes unnecessary after the lamination of the remaining formwork, so that it is removable, and after the lamination is finished It should be removable.

そして、本発明の残存型枠は、後方への突出量が調整自在なスライド板を扶壁の内側面又は外側面に1又は複数設け、各段の残存型枠の扶壁から現況岸壁に向けてスライド板を突出させることにより、前記扶壁と現況岸壁との隙間を前記スライド板で防ぎ、打設するコンクリートが残存型枠を越えて左右にはみ出さないようにする。スライド板は、姿勢調整のために現況岸壁との距離が変化する扶壁を補って、設置した残存型枠の扶壁と現況岸壁との隙間を減らす。スライド板は、扶壁の内側面に設けた場合、残存型枠に残して打設するコンクリートに埋め殺すが、扶壁の外側面に設けた場合、残存型枠に残して前記コンクリートに埋め殺してもよいし、取り外して再利用してもよい。   In the remaining formwork of the present invention, one or a plurality of slide plates whose rearward projecting amount can be adjusted are provided on the inner side surface or the outer side surface of the dredging wall, and the remaining moldwork of each step is directed from the dredging wall to the current quayside. By projecting the slide plate, the gap between the dredged wall and the existing quay wall is prevented by the slide plate, so that the concrete to be placed does not protrude from the left and right beyond the remaining formwork. The slide plate compensates for the dredging wall whose distance from the existing quay changes for posture adjustment, and reduces the gap between the dredging wall of the installed residual formwork and the existing quay. When the slide plate is provided on the inner surface of the wall, it is buried in the concrete to be placed and left on the remaining formwork, but when it is provided on the outer surface of the wall, it is left on the remaining formwork and buried in the concrete. It may be removed and reused.

本発明の残存型枠を用いることにより、施工現場の制約が多いため、設置面を水平に整えることが難しいコンクリート岸壁の補修作業において、設置面に載せる最下段の残存型枠に対して積層していく上層段の残存型枠の姿勢を個々に、しかもがたつきなく調整できる。積層される残存型枠の下層段に対して上層段の残存型枠の姿勢を調整できることから、例えば3段以上に残存型枠を積層する場合、上中段及び下中段それぞれの姿勢を調整し、全体で必要な調整量を各段に分散させて前各段に必要な調整量を小さくできる。   By using the remaining formwork of the present invention, there are many restrictions at the construction site, so in the repair work of concrete quay where it is difficult to level the installation surface, it is laminated on the bottom remaining formwork placed on the installation surface. It is possible to adjust the posture of the remaining upper-stage formwork individually and without rattling. Since it is possible to adjust the posture of the remaining upper form of the upper layer with respect to the lower layer of the remaining molds to be laminated, for example, when stacking the remaining molds in three or more steps, adjust the posture of each of the upper middle and lower middle, It is possible to reduce the adjustment amount necessary for each preceding stage by distributing the adjustment amount necessary for each stage as a whole.

本発明の残存型枠は、左右に延在する凸段差を主壁の上面に設け、前記凸段差と転写関係にある凹段差を左右に延在させて前記主壁の下面に設けることにより、両者を密着又は接近させて、残存型枠の姿勢を調整して上層段及び下層段の残存型枠の主壁間からコンクリートの漏れ出しが防止される。最下段の残存型枠と設置面との隙間は、漏れ出し防止シートで塞ぎ、コンクリートの漏れ出しを防止するが、本発明を利用すれば、漏れ出し防止シートを最下段の残存型枠に限定しながら、全体のコンクリートの漏れ出しを防止できるようになる。   The remaining mold of the present invention is provided with a convex step extending in the left and right on the upper surface of the main wall, and by providing a concave step in transfer relation with the convex step in the left and right on the lower surface of the main wall, Both are brought into close contact with each other, and the posture of the remaining mold is adjusted to prevent leakage of concrete from between the main walls of the upper and lower remaining molds. The gap between the lowermost remaining formwork and the installation surface is closed with a leakage prevention sheet to prevent the leakage of concrete, but if this invention is used, the leakage prevention sheet is limited to the lowermost remaining formwork. However, it becomes possible to prevent leakage of the entire concrete.

主壁の上面及び下面に設けた連結ピン及び連結穴の組み合わせや、主壁の後面に設けた設置ガイドは、上層段及び下層段の残存型枠の積層位置関係を容易に特定したり、高さ調整ボルトによる上層段の姿勢調整に際して前記上層段の残存型枠の脱落を防止したりする。特に、連結ピン及び連結穴の組み合わせは上層段の残存型枠が過度に傾いて脱落させない働きを、また設置ガイドは前記上層段の残存型枠が後方に落下しない働きを有する。こうして、連結ピン及び連結穴の組み合わせや設置ガイドは、上層段の残存型枠の姿勢調整に係る作業能率を向上させる効果をもたらす。   The combination of connecting pins and connecting holes provided on the upper and lower surfaces of the main wall and the installation guide provided on the rear surface of the main wall can be used to easily identify the stacking positional relationship between the remaining formwork in the upper and lower layers, When the posture of the upper layer step is adjusted by the height adjusting bolt, the remaining mold of the upper layer step is prevented from falling off. In particular, the combination of the connecting pin and the connecting hole serves to prevent the upper layer remaining formwork from being excessively inclined and fall off, and the installation guide serves to prevent the upper layer remaining formwork from falling backward. Thus, the combination of the connecting pin and the connecting hole and the installation guide bring about an effect of improving the work efficiency related to the posture adjustment of the remaining formwork in the upper layer.

そして、扶壁の内側面又は外側面に設けたスライド板は、扶壁と現況岸壁との隙間を前記スライド板で塞ぎ、打設するコンクリートが残存型枠を越えて左右にはみ出さないようにする。これは、無駄なコンクリートを減らす働きのほか、残存型枠及び現況岸壁に囲まれた必要な空間に正しくコンクリートを打設する働きを有する。こうして、スライド板は、残存型枠の姿勢調整により扶壁と現況岸壁との不規則な隙間を塞ぎ、無駄のないコンクリートの利用と必要な範囲への前記コンクリートの打設を実現し、作業能率を向上させる効果をもたらす。   The slide plate provided on the inner or outer surface of the dredging wall closes the gap between the dredging wall and the existing quay with the slide plate so that the concrete to be placed does not protrude beyond the left and right sides of the remaining formwork. To do. In addition to reducing wasteful concrete, this has the function of placing concrete correctly in the necessary space surrounded by the remaining formwork and the existing quay. In this way, the slide plate closes the irregular gaps between the dredging wall and the existing quay by adjusting the posture of the remaining formwork, and realizes the use of concrete without waste and the placement of the concrete into the required range, and the work efficiency The effect is improved.

以下、本発明を実施するための形態について図を参照しながら説明する。本発明は、図1〜図3に見られるように、最下段及び最上段の残存型枠2,3に挟まれる中段(上中段及び下中段)の残存型枠1に適用される。しかし、図4及び図5に見られるように、最上段の残存型枠2は、下層段にある上中段の残存型枠1に対応して、凹条段差212に設ける部分に本発明が適用され、また図6及び図8に見られるように、最下段の残存型枠3は、上層段にある下中段の残存型枠1に対応して、高さ調整ボルト4や連結ピン321を設ける部分に本発明が適用される。   Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 3, the present invention is applied to the remaining mold 1 in the middle stage (upper middle stage and lower middle stage) sandwiched between the lowermost and uppermost remaining molds 2 and 3. However, as can be seen in FIGS. 4 and 5, the present invention is applied to the uppermost remaining formwork 2 corresponding to the upper and middle remaining formwork 1 in the lower stage, which is provided in the concave step 212. As shown in FIGS. 6 and 8, the lowermost remaining formwork 3 is provided with height adjusting bolts 4 and connecting pins 321 corresponding to the lower and middle remaining formwork 1 in the upper layer. The present invention is applied to the part.

本例の残存型枠1,2,3は、長尺な主壁11,21,31の左端(図1、図2、図4〜図7参照)又は右端(図3参照)から短尺な扶壁12,22,32が直交して延びる平面視形状がL字状のコンクリートブロックで、左右対称の左側(図1、図2、図4〜図7参照)及び右側(図3参照)を一組として、現況岸壁7(後掲図16参照)に被さる平面視コ字状の単位壁面C(後掲図8参照)を構成する。左右方向に延長する場合、単位壁面Cの隣り合う残存型枠1,2,3の扶壁11,21,31の外側面同士を対向させ、両外側面の間に目地材78を介装することにより、単位壁面C,C間の水密性を実現する。扶壁11,21,31は、奥行きが十分にあるため、前記目地材の介装による水密性は、必要十分である。   The remaining molds 1, 2, and 3 in this example are short ridges from the left end (see FIGS. 1, 2, and 4 to 7) or the right end (see FIG. 3) of the long main walls 11, 21, and 31. The walls 12, 22, 32 are L-shaped concrete blocks extending orthogonally, and the left and right sides (see FIGS. 1, 2, and 4-7) and the right side (see FIG. 3) As a set, a U-shaped unit wall surface C (see FIG. 8 below) covering the current quay 7 (see FIG. 16 below) is formed. In the case of extending in the left-right direction, the outer surfaces of the ribs 11, 21, 31 of the remaining molds 1, 2, 3 adjacent to the unit wall C are opposed to each other, and a joint material 78 is interposed between both outer surfaces. This realizes the water tightness between the unit wall surfaces C and C. Since the anchor walls 11, 21, and 31 have sufficient depth, the watertightness due to the interposition of the joint material is necessary and sufficient.

中段の残存型枠1(図1〜図3)は、主壁11の上面前側に寄って前記主壁11の延在方向に延びる凸段差111を設け、主壁11の下面前側に寄って、前記凸段差111と転写関係で、かつ前記凸段差111と平行に延びる凹段差112を設けている。これにより、中段の残存型枠1を上下に積層する際、上中段の残存型枠1の凹段差112を下中段の残存型枠1の凸段差111に密着又は両者の隙間を蛇行させ、打設するコンクリート74(後掲図18参照)の漏れ出しを防止すると共に、凸段差111に凹段差112が後方から掛合して、下中段の残存型枠1に対して上中段の残存型枠1が前方に逸脱することを防止する。   The remaining mold 1 in the middle stage (FIGS. 1 to 3) is provided with a convex step 111 extending in the extending direction of the main wall 11 toward the front side of the upper surface of the main wall 11, and close to the front side of the lower surface of the main wall 11. A concave step 112 extending in parallel with the convex step 111 and in parallel with the convex step 111 is provided. Thus, when the middle remaining mold 1 is stacked up and down, the concave step 112 of the upper middle remaining mold 1 is brought into close contact with the convex step 111 of the lower middle remaining mold 1 or the gap between the two is meandered. In addition to preventing leakage of the concrete 74 to be installed (see FIG. 18 below), the concave step 112 is engaged with the convex step 111 from the rear, so that the residual mold 1 in the upper middle stage is compared with the residual mold form 1 in the lower middle stage. Is prevented from deviating forward.

主壁11は、扶壁12を延ばす左端(図1及び図2)又は右端(図3)より少し離れた上面と、左右中間より少し右端(図1及び図2)又は左端(図3)に寄った上面とに、高さ調整ボルト用インサート114,114を埋め込んでいる。高さ調整ボルト4は、前記高さ調整ボルト用インサート114,114それぞれに捩じ込み、主壁11の上面からの突出量を加減する。主壁11の上面から突出する左右一対の高さ調整ボルト4,4は、両者の突出量の違いにより、上中段の残存型枠1の左右方向の傾きを調整する。   The main wall 11 has an upper surface slightly apart from the left end (FIGS. 1 and 2) or right end (FIG. 3) extending the wall 12 and a right end (FIGS. 1 and 2) or left end (FIG. 3) slightly from the left and right middle. The height adjusting bolt inserts 114 and 114 are embedded in the approached upper surface. The height adjusting bolt 4 is screwed into each of the height adjusting bolt inserts 114 and 114 to adjust the amount of protrusion from the upper surface of the main wall 11. The pair of left and right height adjustment bolts 4, 4 protruding from the upper surface of the main wall 11 adjust the inclination in the left-right direction of the remaining mold 1 in the upper middle stage depending on the difference in the amount of protrusion between them.

本例の主壁11は、上下2段にそれぞれ5基ずつ左右方向等間隔に並べたジベル筋115を後面に設け、上段に並ぶ前記ジベル筋115の列と上面との間の後面に、左右一対の設置ガイド固定ボルト用インサート113,113と、前記設置ガイド固定ボルト用インサート113,113に挟まれた左右一対の吊り金具用インサート116,116とを設けている。   In this example, the main wall 11 is provided with five diverb muscles 115 arranged at equal intervals in the left-right direction on the upper and lower two tiers on the rear surface. A pair of installation guide fixing bolt inserts 113 and 113 and a pair of left and right hanging metal fitting inserts 116 and 116 sandwiched between the installation guide fixing bolt inserts 113 and 113 are provided.

ジベル筋115は、平面視U字状に曲げた鉄筋で、現況岸壁7から突出させたアンカー72(図16参照)に直接又は連結筋73を介して接続し、設置を終えた残存型枠1の姿勢を保持させる。ジベル筋115の数及び配置は、自由であり、本発明に必須な構成要素ではない。また、ジベル筋115を設ける場合、本例のように平面視U字状に限られるものではなく、自由に設定してよい。   The gibber bar 115 is a rebar bent in a U shape in plan view, and is connected to an anchor 72 (see FIG. 16) protruding from the existing quay 7 directly or via a connecting bar 73, and the remaining form 1 after installation is completed. Hold the posture. The number and arrangement of the gibber muscles 115 are arbitrary and are not essential components of the present invention. In addition, when providing the gibber muscle 115, it is not limited to a U shape in plan view as in this example, and may be set freely.

設置ガイド固定ボルト用インサート113は、主壁11の後面に向かって右及び右から2番目のジベル筋115,115の間に、吊り金具用インサート116と共に等間隔に1基、同じく主壁11の後面に向かって左及び左から2番目のジベル筋115,115の中間に1基設けられる。また、残る吊り金具用インサート116の1基は、同じく主壁11の後面に向かって左から2番目及び3番目のジベル筋115,115の中間に設けられている。   One installation guide fixing bolt insert 113 is placed at the same interval along the rear wall of the main wall 11 between the second and right gibble bars 115 and 115 from the right and the right side of the main wall 11 together with the suspension bracket insert 116. One unit is provided in the middle of the second and second Giberl muscles 115 and 115 from the left. Further, one of the remaining hanging bracket inserts 116 is provided in the middle of the second and third gibber bars 115 and 115 from the left toward the rear surface of the main wall 11.

設置ガイド固定ボルト用インサート113の数及び配置は、自由であるが、上中段の残存型枠1の位置ずれを防止する設置ガイド5の働きを鑑みた場合、2基以上とし、取り付けた設置ガイド5,5が同一線上に並ぶように構成することが好ましい。同様に、吊り金具用インサート116も、安定して残存型枠1をクレーンで吊り下げるため、クレーンフック77を引っ掛ける吊り金具76が複数となる(後掲図8参照)ように、2基以上とし、吊り下げ部位が複数となるようにすることが好ましい。   The number and arrangement of the installation guide fixing bolt inserts 113 are arbitrary. However, in view of the function of the installation guide 5 for preventing the displacement of the remaining mold 1 in the upper middle stage, two or more installation guides are installed. It is preferable that 5, 5 are arranged on the same line. Similarly, in order to stably hang the remaining formwork 1 with a crane, there are two or more suspension metal fittings 76 for hooking the crane hook 77 (see FIG. 8). It is preferable to have a plurality of hanging parts.

このほか、本例の主壁11は、前面の左右中央に誘発目地117を設けている。また、単位壁面Cを構成する左の残存型枠1(図1及び図2)は、右端前側に寄った凸条である左凸縁118を、単位壁面Cを構成する左の残存型枠1(図3)は、左端後側に寄った凸条である右凸縁119を、それぞれ設けている。左凸縁118及び右凸縁119は、密着又は接近して前後方向に掛合することにより、凸段差111及び凹段差112の組み合わせ同様、コンクリート74の漏れを防いだり、左右の残存型枠1,1相互が前後方向に位置ずれすることを防止する働きを有する。   In addition, the main wall 11 of the present example is provided with a trigger joint 117 at the center of the front left and right. Further, the left residual mold 1 (FIGS. 1 and 2) constituting the unit wall surface C has a left convex edge 118 that is a ridge approaching the right end front side, and the left residual mold 1 constituting the unit wall C. (FIG. 3) is provided with a right convex edge 119, which is a ridge approaching the left end rear side. The left convex edge 118 and the right convex edge 119 are brought into close contact with each other and hooked in the front-rear direction to prevent leakage of the concrete 74, as well as the combination of the convex step 111 and the concave step 112. 1 has a function of preventing the mutual displacement of the two in the front-rear direction.

扶壁12は、主壁11から最も離れた後端近傍の上面に高さ調整ボルト用インサート124を、前記上面に寄って前後方向中間の内側面に吊り金具用インサート125をそれぞれ埋め込んでいる。高さ調整ボルト4は、前記高さ調整ボルト用インサート124に捩じ込み、扶壁12の上面からの突出量を加減する。扶壁12の上面から突出する高さ調整ボルト4は、主壁11の上面から突出する高さ調整ボルト4,4に対する相対的な突出量の違いにより、上層段である上中段の残存型枠1の前後方向の傾きを調整する。吊り金具用インサート125は、主壁11の吊り金具用インサート116と相俟って、吊り下げ部位を増やすため、必要に応じて吊り金具76(後掲図8参照)を取り付ける。   The eaves wall 12 has a height adjusting bolt insert 124 embedded in the upper surface in the vicinity of the rear end farthest from the main wall 11 and a suspension fitting insert 125 embedded in the inner side surface in the front-rear direction near the upper surface. The height adjusting bolt 4 is screwed into the height adjusting bolt insert 124 to adjust the amount of protrusion from the upper surface of the eaves wall 12. The height adjustment bolts 4 protruding from the upper surface of the wall 12 are the upper and middle remaining formwork due to the difference in the amount of protrusion relative to the height adjustment bolts 4 and 4 protruding from the upper surface of the main wall 11. Adjust the tilt of 1 in the front-rear direction. The hanging bracket insert 125, together with the hanging bracket insert 116 of the main wall 11, is attached with a hanging bracket 76 (see FIG. 8 below) as necessary to increase the number of hanging parts.

本例の扶壁12は、主壁11と交わる前端の上面(前記主壁11の左端の上面でもある)に連結ピン穴126を設け、円錐台状のピン部分と円柱状の挿入部分とから構成される樹脂部材の連結ピン121の前記挿入部分を前記連結ピン穴126に対して着脱自在に差し込んで上面から前記ピン部分を突出させ、前記連結ピン121の直下にあたる下面に、円錐台状の連結穴122を開口している。上面から突出させる連結ピン121のピン部分と連結穴122とは、転写構造で全く同形状であり、下中段の残存型枠1の上面と上中段の残存型枠1の下面とが完全に接面しない限り、遊嵌関係になり、前記下中段の残存型枠1に対する上中段の残存型枠1の前後方向及び左右方向の位置関係を概略的に決定する働きを有する。   The flange wall 12 of this example is provided with a connecting pin hole 126 on the upper surface of the front end (which is also the upper surface of the left end of the main wall 11) that intersects the main wall 11, and includes a frustoconical pin portion and a cylindrical insertion portion. The insertion portion of the connecting pin 121 of the resin member to be configured is detachably inserted into the connecting pin hole 126 so that the pin portion protrudes from the upper surface, and a truncated cone shape is formed on the lower surface directly below the connecting pin 121. A connecting hole 122 is opened. The pin portion of the connecting pin 121 protruding from the upper surface and the connecting hole 122 have exactly the same shape due to the transfer structure, and the upper surface of the remaining mold frame 1 in the lower middle stage is completely in contact with the lower surface of the remaining mold frame 1 in the upper middle stage. As long as they do not face each other, they are loosely fitted and have the function of roughly determining the positional relationship in the front-rear direction and the left-right direction of the upper middle level residual mold 1 relative to the lower middle level residual mold 1.

このほか、本例の扶壁12は、内側面後縁に沿って上下方向に4個のスライド板固定ボルト用インサート123を並べて埋め込んでいる。スライド板固定ボルト用インサート123は、それぞれにスライド板固定ボルト62を捩じ込み、前記スライド板固定ボルト62を2個一組として上下2段にスライド板6を取り付ける。スライド板6は、扶壁12の後縁からの突出量を調整することにより、前記扶壁12の後縁と現状岸壁7との隙間を塞ぎ、打設するコンクリート74を左右方向に漏れにくくする。   In addition, the flange wall 12 of this example is embedded with four slide plate fixing bolt inserts 123 arranged in the vertical direction along the rear edge of the inner surface. Each of the slide plate fixing bolt inserts 123 is screwed with a slide plate fixing bolt 62, and the slide plate 6 is attached to the upper and lower two stages as a set of two slide plate fixing bolts 62. The slide plate 6 adjusts the amount of protrusion from the rear edge of the dredging wall 12, thereby closing the gap between the trailing edge of the dredging wall 12 and the current quay wall 7 and making the concrete 74 to be placed less likely to leak in the left-right direction. .

最上段の残存型枠2(図4及び図5。図示は左側のみ、右側は後掲図8以下参照)は、中段(上中段及び下中段を含む)の残存型枠1と異なり、主壁21の上面に凸段差がない、つまり上面が平坦で、主壁21の下面前側に寄って前記主壁21の延在方向に延びる凹段差112のみを設けている。これにより、最上段の残存型枠2を上中段の残存型枠1に積層する際、最上段の残存型枠2の凹段差212を上中段の残存型枠1の凸段差111と密着又は接近させ、打設するコンクリート74(後掲図18参照)の漏れ出しを防止すると共に、上中段の残存型枠1に対して最上段の残存型枠2が前方に逸脱することを防止する。   The uppermost remaining formwork 2 (FIGS. 4 and 5; only shown on the left side, see right side of FIG. 8 and subsequent figures) is different from the remaining formwork 1 in the middle stage (including the upper middle stage and the lower middle stage). There is no convex step on the upper surface of 21, that is, the upper surface is flat, and only the concave step 112 extending in the extending direction of the main wall 21 toward the front side of the lower surface of the main wall 21 is provided. Thus, when the uppermost remaining mold 2 is stacked on the upper middle remaining mold 1, the concave step 212 of the uppermost remaining mold 2 is in close contact with or close to the convex step 111 of the upper middle remaining mold 1. This prevents leakage of the concrete 74 to be placed (see FIG. 18 below) and prevents the uppermost remaining mold 2 from deviating forward from the upper middle remaining mold 1.

本例の主壁21は、上記中段の残存型枠1同様、上下2段にそれぞれ5基ずつ左右方向等間隔に並べたジベル筋215を後面に設け、上段に並ぶジベル筋215の列と上面との間の後面に、左右一対の吊り金具用インサート216,216を設けている。ジベル筋215及び吊り金具用インサート216は、中段の残存型枠1のジベル筋115及び吊り金具用インサート116と同じ仕様及び配置とすることにより、運搬又は設置等に際して最上段の残存型枠2と中段の残存型枠1とを同じように扱えるようにする。   The main wall 21 of the present example is provided with the rear side of five upper and lower rows of the dowels 215 arranged at equal intervals in the left and right direction, like the above-mentioned middle mold 1 in the middle stage. A pair of left and right hanging bracket inserts 216, 216 are provided on the rear surface between the two. The gibber bar 215 and the suspension metal fitting insert 216 have the same specifications and arrangement as the gibber bar 115 and the hanger metal fitting insert 116 of the middle remaining mold 1, so that The middle mold 1 can be handled in the same way.

また、本例の主壁21は、上記中段の残存型枠1同様、前面の左右中央に誘発目地117を設けている。そして、単位壁面Cを構成する左の残存型枠2(図4及び図5)は、右端前側に寄った凸条である左凸縁218を、単位壁面Cを構成する左の残存型枠2(図8等参照)は、左端後側に寄った凸条である右凸縁219を、それぞれ設けている。左凸縁218及び右凸縁219は、密着又は接近して前後方向に掛合することにより、コンクリート74の漏れを防いだり、位置ずれを防止したりするのと同じ働きを実現する。   Moreover, the main wall 21 of this example is provided with the induction joint 117 at the center of the left and right of the front surface, like the above-described remaining mold 1 in the middle stage. The left residual mold 2 (FIGS. 4 and 5) constituting the unit wall surface C has a left convex edge 218 which is a ridge approaching the right end front side, and the left residual mold 2 constituting the unit wall C. (Refer to FIG. 8 and the like) are each provided with a right convex edge 219, which is a convex strip approaching the left end rear side. The left convex edge 218 and the right convex edge 219 are brought into close contact with each other and engaged in the front-rear direction, thereby realizing the same function as preventing leakage of the concrete 74 and preventing displacement.

扶壁22は、上面に寄って前後方向中間の内側面に吊り金具用インサート225を埋め込んであり、主壁21の吊り金具用インサート216と相俟って、吊り下げ部位を増やすため、必要に応じて吊り金具76(後掲図8参照)を前記吊り金具用インサート225に取り付ける。本例の扶壁22は、主壁11と交わる前端の下面(前記主壁21の左端の下面でもある)に、円錐台状の連結穴222を開口している。連結穴222は、下層段にある上中段の残存型枠1から突出する連結ピン121のピン部分と転写構造で全く同形状であり、前記上中段の残存型枠1の上面と最上段の残存型枠2の下面とが完全に接面しない限り、遊嵌関係になり、前記上中段の残存型枠1に対する最上段の残存型枠2の前後方向及び左右方向の位置関係を概略的に決定する働きを有する。   The heel wall 22 is embedded with a hanging bracket insert 225 on the inner side surface in the front-rear direction close to the top surface, and in combination with the hanging bracket insert 216 on the main wall 21, it is necessary to increase the number of hanging parts. In response, a hanging bracket 76 (see FIG. 8) is attached to the hanging bracket insert 225. The flange wall 22 of this example has a truncated conical connection hole 222 on the lower surface of the front end that intersects the main wall 11 (also the lower surface of the left end of the main wall 21). The connecting hole 222 has exactly the same shape as the transfer pin and the pin portion of the connecting pin 121 protruding from the upper middle remaining mold 1 in the lower layer, and the upper and uppermost remaining molds 1 remain. As long as the lower surface of the mold 2 is not completely in contact with each other, it is loosely fitted, and the positional relationship in the front-rear direction and the left-right direction of the uppermost remaining mold 2 with respect to the upper middle remaining mold 1 is roughly determined. Has the function of

また、本例の扶壁22は、内側面後縁に沿って上下方向に4個のスライド板固定ボルト用インサート223を並べて埋め込んでいる。スライド板固定ボルト用インサート223は、それぞれにスライド板固定ボルト62を捩じ込み、前記スライド板固定ボルト62を2個一組として上下2段にスライド板6を取り付ける。スライド板6は、扶壁22の後縁からの突出量を調整することにより、前記扶壁22の後縁と現状岸壁7との隙間を塞ぎ、打設するコンクリート74を左右方向に漏れにくくする。   In addition, the saddle wall 22 of this example includes four slide plate fixing bolt inserts 223 arranged side by side in the vertical direction along the rear edge of the inner surface. The slide plate fixing bolt inserts 223 are respectively screwed with the slide plate fixing bolts 62, and the slide plates 6 are attached to the upper and lower two stages as a set of two slide plate fixing bolts 62. The slide plate 6 adjusts the amount of protrusion from the rear edge of the dredging wall 22 to close the gap between the trailing edge of the dredging wall 22 and the current quay wall 7 and make the concrete 74 to be placed difficult to leak in the left-right direction. .

最下段の残存型枠3(図6及び図7。図示は左側のみ、右側は後掲図8以下参照)は、中段(上中段及び下中段を含む)の残存型枠1と異なり、主壁21の下面に凹段差がない、つまり下面が平坦で、主壁31の上面前側に寄って前記主壁31の延在方向に延びる凸段差311を設けている。これにより、最下段の残存型枠3に下中段の残存型枠1を積層する際、中段の残存型枠1の凹段差112を最下段の残存型枠3の凸段差311と密着又は接近させ、打設するコンクリート74(後掲図18参照)の漏れ出しを防止すると共に、最下段の残存型枠3に対して下中段の残存型枠1が前方に逸脱することを防止する。   Unlike the remaining mold 1 in the middle stage (including the upper middle stage and the lower middle stage), the lowermost remaining formwork 3 (FIGS. 6 and 7; only shown on the left side, see right side of FIG. 8 and later) is the main wall. There is no concave step on the lower surface of 21, that is, the lower surface is flat, and a convex step 311 extending in the extending direction of the main wall 31 toward the front side of the upper surface of the main wall 31 is provided. As a result, when the lower middle mold residual mold 1 is stacked on the bottom residual mold 3, the concave step 112 of the middle residual mold 1 is brought into close contact with or close to the convex step 311 of the lower residual mold 3. In addition, leakage of the concrete 74 to be placed (see FIG. 18 described later) is prevented, and the lower and middle remaining molds 1 are prevented from deviating forward with respect to the lowermost remaining mold 3.

主壁31は、扶壁32を延ばす左端より少し離れた上面と、左右中間より少し右端に寄った上面とに、高さ調整ボルト用インサート314,314を埋め込んでいる。高さ調整ボルト4は、前記高さ調整ボルト用インサート314,314それぞれに捩じ込み、主壁31の上面からの突出量を加減する。主壁31の上面から突出する左右一対の高さ調整ボルト4,4は、両者の突出量の違いにより、上層段として積層する下中段の残存型枠1の左右方向の傾きを調整する。   The main wall 31 has height adjustment bolt inserts 314 and 314 embedded in an upper surface slightly extending from the left end extending the flange wall 32 and an upper surface slightly closer to the right end than the left and right middle. The height adjustment bolt 4 is screwed into each of the height adjustment bolt inserts 314 and 314 to adjust the amount of protrusion from the upper surface of the main wall 31. The pair of left and right height adjustment bolts 4, 4 protruding from the upper surface of the main wall 31 adjust the inclination in the left-right direction of the remaining middle frame 1 of the lower middle layer stacked as the upper layer depending on the difference in the protruding amount of both.

本例の主壁31は、上記中段の残存型枠1及び最上段の残存型枠2同様、上下2段にそれぞれ5基ずつ左右方向等間隔に並べたジベル筋315を後面に設け、上段に並ぶ前記ジベル筋315の列と上面との間の後面に、左右一対の設置ガイド固定ボルト用インサート313,313と、前記設置ガイド固定ボルト用インサート313,313に挟まれた左右一対の吊り金具用インサート316,316とを設けている。ジベル筋315、設置ガイド固定ボルト用インサート313及び吊り金具用インサート316は、中段の残存型枠1のジベル筋115、設置ガイド固定ボルト用インサート113及び吊り金具用インサート116と同じ仕様及び配置とすることにより、運搬又は設置等に際して最下段の残存型枠3と中段の残存型枠1とを同ように扱えるようにする。   The main wall 31 of the present example is provided with a dowel bar 315 arranged at equal intervals in the left-right direction in the upper and lower two tiers on the rear surface, similar to the above-mentioned middle residual mold 1 and uppermost residual mold 2 above. A pair of left and right installation guide fixing bolt inserts 313, 313 and a pair of left and right suspension metal fitting inserts 316, 316 sandwiched between the installation guide fixing bolt inserts 313, 313 are arranged on the rear surface between the row of the above-mentioned gibel muscles 315 and the upper surface. Provided. The gibber bar 315, the installation guide fixing bolt insert 313 and the suspension fitting insert 316 have the same specifications and arrangement as the gibber reinforcement 115, the installation guide fixing bolt insert 113 and the suspension fitting insert 116 of the remaining mold 1 in the middle stage. Thus, the lowermost remaining formwork 3 and the middle remaining formwork 1 can be handled in the same way during transportation or installation.

また、本例の主壁31は、上記中段の残存型枠1同様、前面の左右中央に誘発目地317を設けている。そして、単位壁面Cを構成する左の残存型枠3(図6及び図7)は、右端前側に寄った凸条である左凸縁318を、単位壁面Cを構成する左の残存型枠3(図8等参照)は、左端後側に寄った凸条である右凸縁319を、それぞれ設けている。左凸縁318及び右凸縁319は、密着又は接近して前後方向に掛合することにより、コンクリート74の漏れを防いだり、位置ずれを防止したりするのと同じ働きを実現する。   In addition, the main wall 31 of the present example is provided with an induction joint 317 at the center of the left and right sides of the front surface in the same manner as the remaining mold 1 in the middle stage. The left residual mold 3 (FIGS. 6 and 7) constituting the unit wall surface C has a left convex edge 318 which is a ridge approaching the front end of the right end, and the left residual mold 3 constituting the unit wall C. (Refer to FIG. 8 and the like) are each provided with a right convex edge 319, which is a ridge approaching the rear side of the left end. The left convex edge 318 and the right convex edge 319 are brought into close contact with each other and engaged in the front-rear direction, thereby realizing the same function as preventing leakage of the concrete 74 and preventing displacement.

このほか、本例の主壁31は、下面に添って左右方向等間隔に8個のシート固定ボルト用インサート331を後面に埋め込み、主壁33の後面に向かって漏れ出し防止シート33、シート固定板332を順に重ねてシート固定ボルト333を前記シート固定ボルト用インサート331に捩じ込み、漏れ出し防止シート33を下縁から後方へ延ばすように取り付けることができるようにしている。こうして主壁33の後面とシート固定板332とに挟まれた漏れ出し防止シート33は、後方に延ばして設置面71(後掲図16以下参照)上に展開され、前記設置面71と最下段の残存型枠3の主壁31との隙間からコンクリート74が漏れ出ないようにする。   In addition, the main wall 31 of this example has eight seat fixing bolt inserts 331 embedded in the rear surface at equal intervals in the left-right direction along the lower surface, and the leakage prevention sheet 33 and seat fixing toward the rear surface of the main wall 33 The sheet fixing bolt 333 is screwed into the sheet fixing bolt insert 331 with the plates 332 sequentially stacked so that the leakage preventing sheet 33 can be attached to extend rearward from the lower edge. In this way, the leakage preventing sheet 33 sandwiched between the rear surface of the main wall 33 and the sheet fixing plate 332 extends rearward and is deployed on the installation surface 71 (see FIG. 16 and later). The concrete 74 is prevented from leaking from the gap with the main wall 31 of the remaining mold 3.

扶壁32は、主壁31から最も離れた後端近傍の上面に高さ調整ボルト用インサート314を、前記上面に寄って前後方向中間の内側面に吊り金具用インサート325をそれぞれ埋め込んでいる。高さ調整ボルト4は、前記高さ調整ボルト用インサート314に捩じ込み、扶壁32の上面からの突出量を加減する。扶壁32の上面から突出する高さ調整ボルト4は、主壁31の上面から突出する高さ調整ボルト4,4に対する相対的な突出量の違いにより、上層段である下中段の残存型枠1の前後方向の傾きを調整する。吊り金具用インサート325は、主壁31の吊り金具用インサート316と相俟って、吊り下げ部位を増やすため、必要に応じて吊り金具76(後掲図8参照)を取り付ける。   In the flange wall 32, a height adjusting bolt insert 314 is embedded on the upper surface in the vicinity of the rear end farthest from the main wall 31, and a suspension fitting insert 325 is embedded on the inner surface in the front-rear direction near the upper surface. The height adjusting bolt 4 is screwed into the height adjusting bolt insert 314 to adjust the amount of protrusion from the upper surface of the eaves wall 32. The height adjustment bolts 4 protruding from the upper surface of the wall 32 have a difference in the amount of protrusion relative to the height adjustment bolts 4, 4 protruding from the upper surface of the main wall 31. Adjust the tilt of 1 in the front-rear direction. The suspension fitting insert 325 is coupled with the suspension fitting insert 316 on the main wall 31 to attach a suspension fitting 76 (see FIG. 8 described later) as necessary in order to increase the number of hanging parts.

本例の扶壁32は、主壁31と交わる前端の上面(前記主壁31の左端の上面でもある)に連結ピン穴326を設け、円錐台状のピン部分と円柱状の挿入部分とから構成される樹脂部材の連結ピン321の前記挿入部分を前記連結ピン穴326に対して着脱自在に差し込んで上面から前記ピン部分を突出させている。連結ピン221は、上層段にある下中段の残存型枠1に設けられた連結穴122と転写構造で全く同形状であり、最下段の残存型枠3の上面と下中段の残存型枠1の下面とが完全に接面しない限り、遊嵌関係になり、前記最下段の残存型枠3に対する下中段の残存型枠1の前後方向及び左右方向の位置関係を概略的に決定する働きを有する。   The flange wall 32 of this example is provided with a connecting pin hole 326 on the upper surface of the front end that intersects with the main wall 31 (also the upper surface of the left end of the main wall 31), and includes a frustoconical pin portion and a columnar insertion portion. The insertion portion of the connecting pin 321 of the resin member to be configured is removably inserted into the connecting pin hole 326 so that the pin portion protrudes from the upper surface. The connecting pin 221 has exactly the same shape as the connecting hole 122 provided in the lower middle residual mold 1 in the upper layer, and has a transfer structure, and the upper surface of the lower residual mold 3 and the lower middle residual mold 1. As long as the bottom surface of the lower left side is not completely in contact with each other, it is in a loose-fitting relationship and functions to roughly determine the positional relationship in the front-rear direction and the left-right direction of the lower middle mold residual mold 1 with respect to the bottom residual mold 3. Have.

このほか、本例の扶壁32は、内側面後縁に沿って上下方向に4個のスライド板固定ボルト用インサート323を並べて埋め込んでいる。スライド板固定ボルト用インサート323は、それぞれにスライド板固定ボルト62を捩じ込み、前記スライド板固定ボルト62を2個一組としてスライド板6を取り付ける。スライド板6は、扶壁32の後縁からの突出量を調整することにより、前記扶壁32の後縁と現状岸壁7との隙間を塞ぎ、打設するコンクリート74を左右方向に漏れにくくする。   In addition, the flange wall 32 of this example is embedded with four slide plate fixing bolt inserts 323 arranged in the vertical direction along the rear edge of the inner surface. The slide plate fixing bolt inserts 323 are each screwed with the slide plate fixing bolts 62, and the slide plates 6 are attached to the slide plate fixing bolts 62 as a set. The slide plate 6 adjusts the amount of protrusion from the rear edge of the dredging wall 32 to close the gap between the trailing edge of the dredging wall 32 and the current quay 7 and make the concrete 74 to be placed difficult to leak in the left-right direction. .

本例の残存型枠1,2,3は、図8及び図9に見られるように、左右一対で単位壁面Cを構成し、前記単位壁面Cを上下方向に積層していく。残存型枠1,2,3は、それぞれ設置ガイド5及び吊り金具76を取り付け、前記吊り金具76にクレーンフック77を掛けて吊り下げて移動させ、設置面71の上に最下段の残存型枠3を載せ、下層段の残存型枠1,3に取り付けた設置ガイド5に沿って上層段の残存型枠1,2積層していき、積層を終えた残存型枠1,3から順次設置ガイド5及び吊り金具76を取り外す。そして、積層を終えた残存型枠1,2,3から順にスライド板6を取り付けていく。   As shown in FIGS. 8 and 9, the remaining molds 1, 2, and 3 of this example constitute a unit wall surface C in a pair of left and right, and the unit wall surfaces C are stacked in the vertical direction. The remaining molds 1, 2, and 3 are respectively attached with the installation guide 5 and the hanging bracket 76, hung the crane hook 77 on the hanging bracket 76, moved and suspended, and the lowermost remaining mold on the installation surface 71. 3, the remaining molds 1 and 2 in the upper layer are stacked along the installation guide 5 attached to the remaining molds 1 and 3 in the lower layer, and the installation guides are sequentially installed from the remaining molds 1 and 3 that have been stacked. 5 and the hanging bracket 76 are removed. Then, the slide plate 6 is attached in order from the remaining molds 1, 2, and 3 that have been laminated.

設置ガイド5は、例えば下層段である下中段の残存型枠1に対して上層段である上中段の残存型枠1が後方へずれ落ちないように、前記残存型枠1同士の主壁11を面一に揃えることができれば、どのような部材構成又は構造でもよい。本例の設置ガイド5は、図10に見られるように、断面コ字状のチャンネル部材であり、ウェブの一端側に寄って設けたボルト孔に設置ガイド固定ボルト51を挿通し、残存型枠1の設置ガイド固定ボルト用インサート113に前記設置ガイド固定ボルト51を螺着することにより、主壁11に対して着脱自在に取り付ける。   For example, the installation guide 5 has a main wall 11 between the remaining molds 1 so that the upper and lower remaining molds 1 do not slip backward with respect to the lower middle remaining molds 1 that are lower layers. Any member configuration or structure may be used as long as they can be aligned. As shown in FIG. 10, the installation guide 5 of this example is a channel member having a U-shaped cross section, and the installation guide fixing bolt 51 is inserted into a bolt hole provided close to one end side of the web. The installation guide fixing bolt 51 is screwed to the installation guide fixing bolt insert 113 of 1 to attach the main body 11 in a detachable manner.

スライド板6は、残存型枠1,2,3の扶壁12,22,32の後端と現状岸壁7(後掲図16参照)との隙間を埋める前記扶壁12,22,32の延長部材である。本例のスライド板6は、図11に見られるように、前記扶壁12,22,32の突出方向に延びる上下2条の位置調整溝61を設けた金属製の本体板と、前記本体板の上縁及び下縁に取り付ける金属製の補強アングル64とから構成され、上縁に取り付けた補強アングル64に、棒鋼を平面視コ字状に折り曲げて形成される把っ手63を設けている。補強アングル64は、本体板の剛性を高め、打設するコンクリート74(後掲図16参照)に押されて本体板が曲がらないようにする。把っ手63は、作業者がスライド板6を持ち運ぶ際に用いる。   The slide plate 6 is an extension of the ridge walls 12, 22, 32 that fills the gap between the rear ends of the ridge walls 12, 22, 32 of the remaining molds 1, 2, 3 and the current quay 7 (see FIG. 16). It is a member. As shown in FIG. 11, the slide plate 6 of this example includes a metal main body plate provided with two upper and lower position adjusting grooves 61 extending in the protruding direction of the flange walls 12, 22, and 32, and the main body plate. It is composed of a metal reinforcement angle 64 attached to the upper edge and the lower edge, and a grip 63 formed by bending a steel bar in a U shape in plan view is provided on the reinforcement angle 64 attached to the upper edge. . The reinforcing angle 64 increases the rigidity of the main body plate and prevents the main body plate from being bent by being pushed by the concrete 74 to be placed (see FIG. 16 described later). The handle 63 is used when the operator carries the slide plate 6.

スライド板6に設けた位置調整溝61は、上向きの切欠を、前後端を含めて延在方向に等間隔で6ヶ所設けている。扶壁12,22,32のスライド板固定ボルト用インサート124,224,324に捩じ込むスライド板固定ボルト62は、前記位置調整溝61を挿通させ、いずれかの切欠を選択して掛合させ、扶壁12,22,32に対する位置を特定する。これにより、スライド板6は、選択した切欠に依って扶壁12,22,32の後縁からの突出量を6段階で調整できる。また、扶壁12,22,32の後縁から突出させたスライド板6は、切欠にスライド板固定ボルト62を掛合させる限り、前記扶壁12,22,32の後縁からの突出量を安定して維持できる。   The position adjusting groove 61 provided in the slide plate 6 is provided with six upward notches at equal intervals in the extending direction including the front and rear ends. The slide plate fixing bolt 62 to be screwed into the slide plate fixing bolt inserts 124, 224, 324 of the saddle walls 12, 22, 32 is inserted through the position adjusting groove 61, and one of the notches is selected and engaged with each other. Specify the position for 22,32. Thereby, the slide board 6 can adjust the protrusion amount from the rear edge of the collar wall 12,22,32 in six steps according to the notch selected. Further, the slide plate 6 protruded from the rear edge of the saddle wall 12, 22, 32 stabilizes the protruding amount from the rear edge of the saddle wall 12, 22, 32 as long as the slide plate fixing bolt 62 is engaged with the notch. Can be maintained.

本例の場合、下中段の残存型枠1は最下段の残存型枠3に対し、上中段の残存型枠1は前記下中段の残存型枠1に対し、そして最上段の残存型枠2は前記上中段の残存型枠1に対してそれぞれ前後方向又は左右方向の姿勢(傾き)を調整できる。例えば、最下段残存型枠3に対して前方向へ傾いた下中段の残存型枠1に対して上中段の残存型枠1が左方向へ傾けば、前記上中段の残存型枠1は、最下段の残存型枠3に対して前方向及び左方向へ傾くことになる。こうして、本発明を適用して構築するコンクリート岸壁は、個々に姿勢を調整した残存型枠1,2,3全体で、前記コンクリート岸壁の前面を整える。   In the case of this example, the lower middle mold form 1 is in the lowermost remaining mold form 3, the upper middle mold form 1 is in the lower middle remaining mold form 1, and the uppermost remaining mold form 2. Can adjust the posture (tilt) in the front-rear direction or the left-right direction with respect to the remaining mold 1 in the upper middle stage. For example, if the upper middle stage residual mold 1 is tilted to the left with respect to the lower middle residual mold 1 tilted forward with respect to the lowermost residual mold 3, the upper middle residual mold 1 is It tilts forward and leftward with respect to the lowermost remaining formwork 3. Thus, the concrete quay constructed by applying the present invention arranges the front surface of the concrete quay with the entire remaining molds 1, 2, and 3 whose postures are individually adjusted.

姿勢の調整について、上中段及び下中段の残存型枠1,1を挙げて説明する。上中段の残存型枠1は、下中段の残存型枠1の主壁11の上面から突出する左右一対の高さ調整ボルト4,4と、扶壁12の上面から突出する高さ調整ボルト4とに下面を当接させる。これにより、上中段の残存型枠1は、下中段の残存型枠1に対して3つの高さ調整ボルト4,4,4により三点支持される。主壁11の上面から突出する高さ調整ボルト4,4を共に縮めて前方の凸段差111より低くした場合、前記高さ調整ボルト4,4に代わり、前記凸段差111が上中段の残存型枠1の凹段差112に当接する。   Posture adjustment will be described with reference to the upper middle and lower middle molds 1 and 1. The upper middle stage residual mold 1 includes a pair of left and right height adjustment bolts 4, 4 protruding from the upper surface of the main wall 11 of the lower middle stage residual mold 1, and a height adjustment bolt 4 protruding from the upper surface of the eaves wall 12. The lower surface is brought into contact with each other. As a result, the upper middle remaining mold 1 is supported at three points by the three height adjusting bolts 4, 4, 4 with respect to the lower middle remaining mold 1. When the height adjustment bolts 4, 4 protruding from the upper surface of the main wall 11 are both contracted to be lower than the front convex step 111, the convex step 111 remains in the upper middle stage instead of the height adjustment bolts 4, 4. It contacts the concave step 112 of the frame 1.

このとき、主壁11に設けた左右一対の高さ調整ボルト4,4が左右に離れ、かつ扶壁12に設けた高さ調整ボルト4が前記主壁11の高さ調整ボルト4,4から後方に離れていれば、上中段の残存型枠1の重心は、高さ調整ボルト4,4,4に囲まれた仮想的な三角形の範囲に収まり、上中段の残存型枠1の傾きが大きくない限り、前記上中段の残存型枠1が高さ調整ボルト4,4,4からずり落ちる心配はない。実際には、設置を終えた残存型枠1の姿勢を固定するため、現状岸壁7から突出させたアンカー72とジベル筋115とを連結筋73により連結することから、上中段の残存型枠1は前記連結完了まで高さ調整ボルト4,4,4からずり落ちなければよい。   At this time, the pair of left and right height adjustment bolts 4, 4 provided on the main wall 11 are separated from each other left and right, and the height adjustment bolt 4 provided on the wall 12 is removed from the height adjustment bolts 4, 4 of the main wall 11. If it is separated backward, the center of gravity of the remaining middle form 1 in the upper middle is within the range of a virtual triangle surrounded by the height adjustment bolts 4, 4, 4, and the inclination of the remaining middle form 1 in the upper middle As long as it is not large, there is no fear that the upper and middle remaining molds 1 will fall off the height adjustment bolts 4, 4, 4. Actually, in order to fix the posture of the remaining formwork 1 after the installation, the anchor 72 projecting from the current quay 7 and the gibber bar 115 are connected by the connecting bar 73, and therefore, the upper and middle remaining formwork 1 Does not have to slide down from the height adjusting bolts 4,4,4 until the connection is completed.

主壁11に設けた高さ調整ボルト4,4に代わって上中段の残存型枠1の凹段差112を下中段の残存型枠1の凸段差111に当接させた場合も同様で、扶壁12に設けた高さ調整ボルト4が前記凸段差111から後方に離れていれば、上中段の残存型枠1の重心は、凸段差111及び高さ調整ボルト4に囲まれた仮想的な三角形の範囲に収まり、上中段の残存型枠1の傾きが大きくない限り、前記上中段の残存型枠1が凸段差111及び高さ調整ボルト4からずり落ちる心配はない。この場合も、現状岸壁7から突出させたアンカー72とジベル筋115とを連結筋73により連結し、上中段の残存型枠1の姿勢を固定する。   The same applies when the concave step 112 of the remaining mold 1 in the upper middle stage is brought into contact with the convex step 111 of the remaining mold 1 in the lower middle stage instead of the height adjusting bolts 4, 4 provided on the main wall 11. If the height adjustment bolt 4 provided on the wall 12 is separated rearward from the convex step 111, the center of gravity of the remaining mold 1 in the upper middle stage is an imaginary area surrounded by the convex step 111 and the height adjustment bolt 4. As long as it falls within the triangular range and the inclination of the upper middle stage residual mold 1 is not large, there is no fear that the upper middle stage residual mold 1 slides down from the convex step 111 and the height adjusting bolt 4. Also in this case, the anchor 72 projecting from the current quay 7 and the gibber bar 115 are connected by the connecting bar 73, and the posture of the upper and middle remaining formwork 1 is fixed.

上中段の残存型枠1は、図12に見られるように、下中段の残存型枠1の主壁11に設けた右(図12中左)の高さ調整ボルト4の突出量が、前記主壁11に設けた左(図12中右)の高さ調整ボルト4及び扶壁12に設けた高さ調整ボルト4の突出量より大きければ、左方に下り勾配となるように傾く(図12は後面側から見ているため、左右が逆)。図示を省略するが、上中段の残存型枠1は、下中段の残存型枠1の主壁11に設けた右(図12中左)の高さ調整ボルト4の突出量が、前記主壁11に設けた左(図12中右)の高さ調整ボルト4及び扶壁12に設けた高さ調整ボルト4の突出量より小さければ、前述と逆に、右方に下り勾配となるように傾く。   As shown in FIG. 12, the upper middle level residual mold 1 has a protrusion amount of the right (left in FIG. 12) height adjustment bolt 4 provided on the main wall 11 of the lower middle level residual mold 1. If the height adjustment bolt 4 on the left (right side in FIG. 12) provided on the main wall 11 and the height adjustment bolt 4 provided on the wall 12 are larger than the protruding amount, it tilts to the left so as to form a downward slope (see FIG. Since 12 is seen from the rear side, the left and right are reversed. Although not shown in the drawing, the upper middle stage residual mold 1 has a protruding amount of the right (left in FIG. 12) height adjustment bolt 4 provided on the main wall 11 of the lower middle stage residual mold 1. If the height adjustment bolt 4 on the left (right in FIG. 12) provided on 11 and the height adjustment bolt 4 provided on the wall 12 are smaller than the protruding amount, a downward slope is set to the right, contrary to the above. Tilt.

高さ調整ボルト4は、高さ調整ボルト用インサート114(124)に捩じ込めば突出量が小さくなる(図14)。高さ調整ボルト4の突出量が凸段差111の高さより低くなると、上中段の残存型枠1の下面は高さ調整ボルト4から離れ、凹段差112を下中段の残存型枠1の凸段差111に当接させる。また、逆に高さ調整ボルト用インサート114(124)から緩めれば突出量が大きくなる(図15)。高さ調整ボルト4の突出量は、下中段の残存型枠1に上中段の残存型枠1を積層する前に調整しておく。   When the height adjusting bolt 4 is screwed into the height adjusting bolt insert 114 (124), the protruding amount becomes small (FIG. 14). When the protruding amount of the height adjustment bolt 4 is lower than the height of the convex step 111, the lower surface of the upper middle level residual mold 1 is separated from the height adjustment bolt 4, and the concave level 112 is protruded from the lower middle level. Contact 111. On the other hand, if the height adjustment bolt insert 114 (124) is loosened, the amount of protrusion increases (FIG. 15). The amount of protrusion of the height adjusting bolt 4 is adjusted before the upper middle stage residual mold 1 is stacked on the lower middle residual mold 1.

上中段の残存型枠1の左右方向の姿勢は、下中段の残存型枠1の主壁11に設けた右の高さ調整ボルト4の突出量と、前記主壁11に設けた左の高さ調整ボルト4及び扶壁12に設けた高さ調整ボルト4の突出量との相対的な差により決定される。例えば主壁11に設けた左の高さ調整ボルト4及び扶壁12に設けた高さ調整ボルト4を突出させても、主壁11に設けた右の高さ調整ボルト4をより突出させれば、上中段の残存型枠1は、左方に下り勾配に傾く。主壁11に設けた左の高さ調整ボルト4及び扶壁12に設けた高さ調整ボルト4の突出量が凸段差111より低くなると、上中段の残存型枠1は、下中段の残存型枠1の右の高さ調整ボルト4と凸段差111の左方とにより支持され、左方に下り勾配に傾く。   The left and right postures of the upper middle stage residual mold 1 are determined by the amount of protrusion of the right height adjusting bolt 4 provided on the main wall 11 of the lower middle residual mold 1 and the left height provided on the main wall 11. This is determined by the relative difference between the height adjustment bolt 4 and the protruding amount of the height adjustment bolt 4 provided on the wall 12. For example, even if the left height adjustment bolt 4 provided on the main wall 11 and the height adjustment bolt 4 provided on the wall 12 are protruded, the right height adjustment bolt 4 provided on the main wall 11 can be protruded more. For example, the upper left middle mold 1 is inclined downward to the left. When the protruding amount of the left height adjustment bolt 4 provided on the main wall 11 and the height adjustment bolt 4 provided on the wall 12 is lower than the convex step 111, the upper middle stage residual mold 1 is the lower middle stage residual mold. It is supported by the height adjustment bolt 4 on the right side of the frame 1 and the left side of the convex step 111, and tilts downward to the left.

また、上中段の残存型枠1は、図13に見られるように、下中段の残存型枠1の主壁11に設けた左右一対の高さ調整ボルト4,4の突出量より、下中段の残存型枠1の扶壁12に設けた高さ調整ボルト4の突出量を大きくすれば、前方に下り勾配に傾く。図示を省略するが、上中段の残存型枠1は、下中段の残存型枠1の主壁11に設けた左右一対の高さ調整ボルト4,4の突出量より、下中段の残存型枠1の扶壁12に設けた高さ調整ボルト4の突出量を小さくすれば、後方に下り勾配に傾く。高さ調整ボルト4の突出量は、下中段の残存型枠1に上中段の残存型枠1を積層する前に調整しておく。   Further, as shown in FIG. 13, the upper and middle remaining molds 1 have lower and middle heights from the protruding amounts of the pair of left and right height adjustment bolts 4 and 4 provided on the main wall 11 of the lower middle mold. If the protruding amount of the height adjusting bolt 4 provided on the ridge wall 12 of the remaining mold 1 is increased, it will be inclined forward downward. Although not shown in the drawing, the upper and middle remaining molds 1 have lower and middle remaining molds because of the protruding amounts of the pair of left and right height adjustment bolts 4, 4 provided on the main wall 11 of the lower middle remaining mold 1. If the protruding amount of the height adjusting bolt 4 provided on the one wall 12 is reduced, it will be inclined backward. The amount of protrusion of the height adjusting bolt 4 is adjusted before the upper middle stage residual mold 1 is stacked on the lower middle residual mold 1.

上中段の残存型枠1の前後方向の姿勢は、下中段の残存型枠1の主壁11に設けた左右一対の高さ調整ボルト4,4の突出量と、下中段の残存型枠1の扶壁12に設けた高さ調整ボルト4の突出量との相対的な差により決定される。例えば主壁11に設けた左右一対の高さ調整ボルト4,4を突出させても、扶壁12に設けた高さ調整ボルト4をより突出させれば、上中段の残存型枠1は、前方に下り勾配に傾く。主壁11に設けた高さ調整ボルト4,4の突出量が凸段差111より低くなると、上中段の残存型枠1は、下中段の残存型枠1の凸段差111と扶壁12に設けた高さ調整ボルト4とにより支持され、前方に下り勾配に傾く。   The posture of the upper middle stage residual mold 1 in the front-rear direction is determined by the amount of protrusion of the pair of left and right height adjustment bolts 4 and 4 provided on the main wall 11 of the lower middle stage residual mold 1 and the lower middle stage residual mold 1. This is determined by a relative difference from the protruding amount of the height adjusting bolt 4 provided on the wall 12 of the wall. For example, even if a pair of left and right height adjustment bolts 4, 4 provided on the main wall 11 is protruded, if the height adjustment bolt 4 provided on the wall 12 is further protruded, the upper and middle remaining formwork 1 is Tilt down to the front. When the protruding amount of the height adjustment bolts 4, 4 provided on the main wall 11 is lower than the convex step 111, the upper middle level residual mold 1 is provided on the convex level 111 and the reed wall 12 of the lower middle level residual mold 1. It is supported by the height adjustment bolt 4 and tilts downward in the forward direction.

このように上中段の残存型枠1を傾けて下中段の残存型枠1に積層する際、下中段の残存型枠1に設置ガイド5を取り付けておくと、前記設置ガイド5に添わせた上中段の残存型枠1が後方(図12中紙面手前)へ逸脱することを防止できる。また、下中段の残存型枠1に設けた連結ピン121を上中段の残存型枠1の連結穴に差し込むことにより、上中段の残存型枠1がどのように傾いていても、下中段の残存型枠1に対する位置関係を特定できるため、上中段の残存型枠1を下中段の残存型枠1に積層する際、前記設置ガイド5から上中段の残存型枠1が逸脱することも抑制又は防止できる。   When the upper middle remaining mold 1 is tilted and stacked on the lower middle remaining mold 1, the installation guide 5 is attached to the lower middle remaining mold 1, and the installation guide 5 is attached. It is possible to prevent the remaining mold 1 in the upper middle stage from deviating backward (before the paper surface in FIG. 12). In addition, by inserting the connecting pins 121 provided in the lower middle stage residual mold 1 into the coupling holes of the upper middle residual mold 1, the lower middle stage no matter how the upper middle residual mold 1 is inclined. Since the positional relationship with respect to the remaining mold 1 can be specified, the upper and middle remaining molds 1 are also prevented from deviating from the installation guide 5 when the upper middle remaining mold 1 is stacked on the lower middle remaining mold 1. Or it can be prevented.

コンクリート岸壁の構築は、次の通りである。まず、図16に見られるように、現況岸壁7の前方で整えられた設置面71の上に最下段の残存型枠3を載置した後、上述のように姿勢を調整しながら中段の残存型枠1,1、そして最上段の残存型枠2を積層していく。設置面71は、本例のように砕石を並べただけの構成のほか、コンクリートを打設して平坦面として構成される場合もある。いずれの場合も、最下段の残存型枠3と設置面71との間は、前記残存型枠3に取り付けられて後方に向けて展開した漏れ出しシート33により塞がれる(図8参照)ため、打設されるコンクリート74が漏れ出す虞がない。   The construction of the concrete quay is as follows. First, as shown in FIG. 16, after the lowermost residual formwork 3 is placed on the installation surface 71 arranged in front of the current quay 7, the middle residual remains while adjusting the posture as described above. The molds 1 and 1 and the uppermost remaining mold 2 are stacked. The installation surface 71 may be configured as a flat surface by placing concrete in addition to the configuration in which crushed stones are arranged as in this example. In any case, the space between the lowermost remaining formwork 3 and the installation surface 71 is blocked by the leaking sheet 33 attached to the remaining formwork 3 and developed rearward (see FIG. 8). There is no possibility that the concrete 74 to be placed leaks out.

残存型枠1,2,3は、現況岸壁7から突出させたアンカー72とそれぞれのジベル筋115,215,315とを、連結筋73を介して接続し、調整された姿勢を保持する。アンカー72、ジベル筋115,215,315及び連結筋73は、いずれも金属製であるから、相互の連結は溶接による。また、下層段(最下段、下中段又は上中段)の残存型枠1,3は、上層段(下中段、上中段又は最上段)の残存型枠1,2を積層する際、連結穴122,222及び連結ピン121,321を嵌合させ、主壁11,31の後面に取り付けた設置ガイド5を主壁11,21に添わせることにより、上層段の残存型枠1,2の後方脱落を防止する。設置ガイド5及び吊り金具76は、上層段の残存型枠1,2を積層し、アンカー73に接続すれば、取り外す。   The remaining molds 1, 2, and 3 connect the anchor 72 projecting from the current quay 7 and the respective gibber muscles 115, 215, and 315 via the connecting bars 73, and maintain the adjusted posture. Since the anchor 72, the gibber bars 115, 215, 315 and the connecting bar 73 are all made of metal, the mutual connection is by welding. Further, the remaining molds 1 and 3 in the lower layer (lowermost, lower middle or upper middle) are connected to the connecting holes 122 and 222 when the remaining molds 1 and 2 in the upper (lower middle, upper middle or uppermost) are stacked. Further, the connecting pins 121 and 321 are fitted, and the installation guide 5 attached to the rear surface of the main walls 11 and 31 is attached to the main walls 11 and 21, thereby preventing the remaining molds 1 and 2 in the upper layer from falling backward. The installation guide 5 and the hanging metal fitting 76 are removed when the remaining upper form frames 1 and 2 are laminated and connected to the anchor 73.

アンカー73に接続して姿勢が保持された残存型枠1,2,3は、それぞれの扶壁12,22,32の内側面(図17中上側)又は外側面(図17中下側)に、突出量を調整しながらスライド板6を取り付ける。本例のスライド板6は、側面視長方形であるため、扶壁12,22,32の後端と現況岸壁7との隙間を完全に塞ぐものではないが、スライド板6の後縁に合わせて現況岸壁7を整形できるため、前記隙間をほとんど塞ぐことができる(図16参照)。また、現況岸壁7の断面形状が予め詳細に分かっていれば、スライド板6の後縁を前記断面形状の転写形状にして、隙間をほとんど塞ぐようにすることもできる。   The remaining molds 1, 2, and 3 that are connected to the anchor 73 and maintained in the posture are arranged on the inner side surface (upper side in FIG. 17) or the outer side surface (lower side in FIG. 17) of each wall 12, 22, and 32, respectively. The slide plate 6 is attached while adjusting the protruding amount. Since the slide plate 6 of this example is rectangular when viewed from the side, it does not completely close the gap between the rear ends of the dredging walls 12, 22, 32 and the existing quay wall 7, but according to the rear edge of the slide plate 6. Since the existing quay 7 can be shaped, the gap can be almost closed (see FIG. 16). Further, if the cross-sectional shape of the current quay 7 is known in detail, the rear edge of the slide plate 6 can be made a transfer shape of the cross-sectional shape so that the gap is almost closed.

残存型枠1,2,3が隣り合う場合、目地材78を介して並ぶ扶壁12,22,32の何れか一方の内側面にスライド板6を取り付ける。スライド板6を取り付けた残存型枠1,2,3は、前記スライド板6までの範囲にコンクリート74が打設される。スライド板6が取り付けられない残存型枠1,2,3は、並ぶ扶壁12,22,32に取り付けられたスライド板6までコンクリート74が回り込み、扶壁12,22,32を跨いで打設する。残存型枠1,2,3が端の場合、扶壁12,22,32の外側面にスライド板6を取り付け、打設したコンクリート74の固化後、適宜スライド板6を回収するとよい。   When the remaining molds 1, 2, and 3 are adjacent to each other, the slide plate 6 is attached to one of the inner surfaces of the ridge walls 12, 22, and 32 that are lined up through the joint material 78. The remaining molds 1, 2, 3 to which the slide plate 6 is attached are placed with concrete 74 in the range up to the slide plate 6. The remaining molds 1, 2, and 3 to which the slide plate 6 cannot be attached are placed with the concrete 74 around the slide plate 6 attached to the side walls 12, 22, and 32 and straddling the side walls 12, 22, and 32. To do. When the remaining molds 1, 2, and 3 are at the ends, the slide plate 6 is attached to the outer side surfaces of the walls 12, 22, and 32, and after the cast concrete 74 is solidified, the slide plate 6 may be appropriately recovered.

残存型枠1,2,3は、図17に見られるように、左右一対で平面視コ字状の単位壁面Cを構成し、前記単位壁面Cの開いた後方を現況岸壁7で塞いで、略閉鎖空間Cを構成する。コンクリート74は、図18に見られるように、前記略閉鎖空間Cに打設される。このとき、アンカー72、ジベル筋115,215,315及び連結筋73はもちろん、それぞれの扶壁12,22,32の内側面に取り付けられたスライド板6(図17中上側)もコンクリート74に埋め殺しされる。スライド板6は、それぞれの扶壁12,22,32の外側面に取り付けられた場合、打設したコンクリート74が固化した後、取り外して再利用してもよい。   As shown in FIG. 17, the remaining molds 1, 2, and 3 constitute a pair of left and right unit wall surfaces C that are U-shaped in plan view, and the open rear side of the unit wall surfaces C is closed with the current quay wall 7, A substantially closed space C is formed. The concrete 74 is placed in the substantially closed space C as seen in FIG. At this time, the slide plate 6 (upper side in FIG. 17) attached to the inner surfaces of the anchor walls 12, 22, 32 as well as the anchor 72, the dowel bars 115, 215, 315 and the connecting bars 73 are buried in the concrete 74. When the slide plate 6 is attached to the outer side surfaces of the respective ridge walls 12, 22, 32, it may be removed and reused after the cast concrete 74 is solidified.

打設するコンクリート74は、漏れ出し防止シート33により、最下段の残存型枠3と設置面71との隙間からの漏れ出しが防止される。また、打設するコンクリート74は、凸段差111,311と凹段差112,212とを密着又は両者の隙間を蛇行させることにより、残存型枠1,2,3間から前方への漏れ出しが防止される。そして、コンクリート74は、通常粘性の高いものが使用されるため、扶壁12,22,32の後端と現況岸壁7との間をスライド板6で塞ぐことにより、積層された残存型枠1,2,3から左右方向への漏れ出しが抑制される(漏れ出しが少なくなる)。こうして、コンクリート74は、残存型枠1,2,3と現況岸壁7とに囲まれた略閉鎖空間Cに打設される。   The concrete 74 to be placed is prevented from leaking from the gap between the lowermost remaining formwork 3 and the installation surface 71 by the leak prevention sheet 33. Further, the concrete 74 to be placed is prevented from leaking forward from between the remaining molds 1, 2, and 3 by closely contacting the convex steps 111 and 311 and the concave steps 112 and 212 or meandering the gap between the two. Since the concrete 74 is usually made of a highly viscous material, the remaining formwork 1 is laminated by closing the space between the rear ends of the walls 12, 22, 32 and the existing quay 7 with the slide plate 6. , 2 and 3 are prevented from leaking in the left-right direction (leakage is reduced). In this way, the concrete 74 is placed in a substantially closed space C surrounded by the remaining formwork 1, 2, 3 and the current quay 7.

残存型枠1,2,3が構成する単位壁面Cは、対向する扶壁12,22,32間に目地材78を挟んで並べていく(本例は、図17中上方に向けて並べていく)。そして、コンクリート74が打設された単位壁面Cの上にコンクリート製の天端工部75を設置すれば、図18に見られるように、コンクリート岸壁の構築が完了する。単位岸壁を構成する左右一対の残存型枠1,2,3は、それぞれ誘発目地117,217,317があり、隣り合う単位岸壁の対向する扶壁12,22,32間に目地材78を介装している。このため、本例のコンクリート岸壁は、外部から衝撃を受けた残存型枠1,2,3のみが破損し、しかも前記破損範囲を誘発目地117,217,317と目地材78との間に留めることができる。   The unit wall surfaces C formed by the remaining molds 1, 2, and 3 are arranged with the joint material 78 sandwiched between the opposing wall surfaces 12, 22, and 32 (this example is arranged upward in FIG. 17). . Then, if the concrete ceiling work section 75 is installed on the unit wall surface C on which the concrete 74 is placed, the construction of the concrete quay is completed as seen in FIG. The pair of left and right residual molds 1, 2, and 3 constituting the unit quay have induction joints 117, 217, and 317, respectively, and a joint material 78 is interposed between the opposite anchor walls 12, 22, and 32 of the adjacent unit quay. . Therefore, in the concrete quay of this example, only the remaining molds 1, 2, and 3 that have been impacted from the outside are damaged, and the damage range can be kept between the induction joints 117, 217, and 317 and the joint material 78.
