Description

本発明は、コンクリートの打設空間を区画形成する2つの型枠用合板を、相互に所定の間隔に維持して固定保持するための型枠保持金具およびその型枠保持方法の技術に関する。   The present invention relates to a technique of a mold holding metal fitting and a mold holding method for holding and fixing two mold plywoods that define a concrete placement space at a predetermined distance from each other.

一般に、コンクリート壁体を構築するにあたっては、2つの型枠板をセパレータで相互に所定の間隔に固定保持してコンクリートの打設空間を区画形成し、当該コンクリート打設空間内に生コンクリートを打設するようにしているが、このようなコンクリート壁体の構築方法として、特開2001−173232号公報にて開示されている技術が知られている。   In general, when constructing a concrete wall body, two form plates are fixedly held by a separator at a predetermined interval to form a concrete placement space, and ready-mixed concrete is placed in the concrete placement space. As a method for constructing such a concrete wall, a technique disclosed in Japanese Patent Application Laid-Open No. 2001-173232 is known.

即ち、当該公報には、図10(a)〜(c)に示すように、型枠支持用コーン1と、軸足2と、フォームタイ3とによってセパレータ4の両端に一対の型枠板5を固定保持して型枠6を組み立て、当該型枠6内のコンクリート打設空間にコンクリート7を打設してコンクリート7が固化した後、軸足2を取り外して、型枠板5を撤去するようにしたコンクリート壁構築方法の技術が示されている。   That is, in this publication, as shown in FIGS. 10A to 10C, a pair of mold plates 5 are formed at both ends of a separator 4 by a mold support cone 1, a shaft foot 2, and a foam tie 3. The mold 6 is assembled by fixing and holding the concrete. After the concrete 7 is cast in the concrete placing space in the mold 6 and the concrete 7 is solidified, the shaft foot 2 is removed and the mold plate 5 is removed. The technique of the concrete wall construction method which was made is shown.

上記型枠支持用コーン1は、截頭円錐状に形成されて小径側端部が外側、大径側端部が内側に位置するように配置されるコーン本体1aと、このコーン本体1aの中心部に同軸に埋設された金属製の雌ねじ筒1bとからなり、コーン本体1aは、モルタルにアクリル系樹脂エマルジョンを混和させたものが加圧成型されて形成されている。また、図10(b)に示すように、雌ねじ筒1bの外側端面はコーン本体1aの外側端面より内方へ没入されて空洞部8が形成されている。   The cone 1 for supporting the formwork is formed in a truncated cone shape, and is arranged such that a small-diameter side end is located outside and a large-diameter side end is located inside, and the center of the cone body 1a The cone main body 1a is formed by pressure-molding a mortar mixed with an acrylic resin emulsion. As shown in FIG. 10B, the outer end face of the female screw cylinder 1b is recessed inward from the outer end face of the cone body 1a to form a cavity portion 8.

コンクリート壁体の構築に際しては、先ず、型枠支持用コーン1の雌ねじ筒1bの内端側にセパレータ4の端部をねじ込むとともに、当該雌ねじ筒1bの外端側には軸足2の内端部をねじ込む。そして当該軸足2の外端部に型枠板5を係止してからフォームタイ3を螺着して、型枠支持用コーン1とフォームタイ3との間に型枠板5を挟んでコンクリート型枠6を組み立てて固定保持する。そして、この型枠6内にコンクリートを7打設し、当該コンクリート7が固化した後、軸足2を取り外して型枠6を解体する。そして、コーン本体1aの空洞部8には、これを埋める合成樹脂またはゴム製の栓体9を充填して覆う。
特開2001−173232号公報
In constructing the concrete wall, first, the end portion of the separator 4 is screwed into the inner end side of the female screw cylinder 1b of the formwork support cone 1, and the inner end of the shaft foot 2 is set on the outer end side of the female screw cylinder 1b. Screw the part. Then, after the mold plate 5 is locked to the outer end portion of the shaft foot 2, the foam tie 3 is screwed, and the mold plate 5 is sandwiched between the mold support cone 1 and the foam tie 3. The concrete form 6 is assembled and fixedly held. Then, the concrete 7 is placed in the mold 6 and after the concrete 7 is solidified, the shaft foot 2 is removed and the mold 6 is disassembled. Then, the hollow portion 8 of the cone body 1a is filled and covered with a plug 9 made of synthetic resin or rubber for filling it.
JP 2001-173232 A

しかしながら、上記従来の型枠支持用コーン1を用いたコンクリート壁体の構築方法では、以下のような問題点があった。即ち、上記の型枠支持用コーン1は雌ねじ筒1bの外周に裁頭円錐形状をなしたコンクリート製のコーン本体1aを一体化させて設けているので、当該型枠支持用コーン1を部品として箱詰めすると、箱体の重量が嵩んで重くなるばかりか容積も嵩張り、現場への搬入時等における可搬性に難点があった。また、その搬入時の振動等によって箱詰めした型枠支持用コーン同士がぶつかり合うと、コンクリート製のコーン本体1a部分に割れ等の損傷を来すこともあった。   However, the above-described conventional method for constructing a concrete wall using the mold support cone 1 has the following problems. That is, since the above-mentioned mold support cone 1 is provided by integrating the cone cone body 1a having a truncated cone shape on the outer periphery of the female screw cylinder 1b, the mold support cone 1 is used as a part. When packed in a box, not only the weight of the box is increased, but the volume is also increased, and there is a difficulty in portability at the time of delivery to the site. In addition, when the formwork supporting cones packed in the box collide with each other due to vibration at the time of carrying in, the concrete cone main body 1a may be damaged such as cracks.

さらに、型枠6を解体して型枠板5を撤去すると、コンクリート製のコーン本体1aの外端面が壁体の外表面に円形に露出することになるが、コーン本体1aのコンクリートの色と打設された壁体のコンクリート7の色とを実際上同一にすることはできないため、構築された壁面の全体に多数の円形模様が生じてしまい、美観を損ねてしまうという課題もあった。   Further, when the mold 6 is disassembled and the mold plate 5 is removed, the outer end surface of the concrete cone body 1a is exposed in a circular shape on the outer surface of the wall body. Since the color of the concrete 7 of the placed wall body cannot be made practically the same, a large number of circular patterns are formed on the entire constructed wall surface, resulting in a problem that the aesthetic appearance is impaired.

本発明は、以上の課題に鑑みてなされたものであり、その目的は、軽量で可搬性に優れ、壁体構築後の壁面にコンクリート色の異なる円形模様が生じることが無く、美観の可及的な向上が図れるコンクリート壁体の構築方法、及びその構築方法に用いる型枠保持具、並びにその構築方法によって形成されるコンクリート壁体構造を提供することにある。   The present invention has been made in view of the above problems, and its purpose is to be lightweight and excellent in portability, without causing a circular pattern with a different concrete color on the wall surface after the construction of the wall, and to be possible for aesthetics.

As shown in the figure, the female screw cylinder 26 is made of a metal such as iron or aluminum, and forms a cylindrical body with a female screw portion 26a extending over the entire inner surface thereof. A partition wall 26b for partitioning the internal space to the left and right is provided at a substantially central portion in the axial length direction of the female screw portion 26a. Here, the partition wall 26b is formed by inserting a metal ball such as aluminum into the female screw cylinder 26 and sandwiching the metal ball with a rod or the like from the left and right to crush and plastically deform it. In addition, a ring 26c that protrudes outward in the radial direction is provided integrally with the outer peripheral portion of the female screw cylinder 26 in the vicinity of one end side thereof by welding or the like. It is provided to contribute to securing fixing properties.

図3は上記雌ねじ筒26に螺合される軸足28を示す側面図である。図示するように、この軸足28には、その両端部に雄ねじ部28a,28bが形成されており、その一端側の雄ねじ部28aは他端側の雄ねじ部28bよりもその有効ねじ長が短くなっていて、当該有効ねじ長の短い一端側の雄ねじ部28aが雌ねじ筒26に螺合される様になっている。また、両雄ねじ部28a,28b間には非ねじ部28cが設けられていて、この非ねじ部28cには図示していないがスパナ等のレンチを係合させるための一対の平行面が形成されている。   FIG. 3 is a side view showing the shaft foot 28 screwed into the female screw cylinder 26. As shown in the figure, the shaft foot 28 is formed with male screw portions 28a and 28b at both ends thereof, and the effective screw length of the male screw portion 28a on one end side is shorter than that of the male screw portion 28b on the other end side. The male screw portion 28a on one end side with the short effective screw length is screwed into the female screw cylinder 26. A non-threaded portion 28c is provided between the male screw portions 28a and 28b, and a pair of parallel surfaces for engaging a wrench such as a spanner is formed in the non-threaded portion 28c, although not shown. ing.

図4は上記凹部形成用リング30を示すもので、(a)は正面図、(b)は側面図である。図示するように、この凹部形成用リング30は円形の板の中心部に上記軸足28の径よりやや大きな挿通孔30aが空けられて環状に形成されている。そして、その一側面の外径D2は上記雌ねじ筒26の外径にほぼ等しい円形をなす一方、他側面の外径D1はその一側面の外径よりも一回り大きい円形をなしている。即ち、凹部形成用リング30の周面はテーパー状に傾斜して、その外形形状は円錐台状になっている。また、当該凹部形成用リング30は樹脂で形成され、その樹脂中には炭素繊維等の補強繊維を混合して、その剛性を高めて潰れ難くしてある。ここで、この凹部形成用リング30は雌ねじ筒26の外側端面を型枠板22から離間させることで、図5Bの(VII)に示すように、構築される壁体36の表面から当該雌ねじ筒26の外側端面を窪ませて凹部38を形成し、図5Cの(IIX),(IX)に示すように、この凹部38内に雌ねじ筒26の外端面を被覆するための栓体40を装着すべく設けられるものである。   FIG. 4 shows the recess forming ring 30, wherein (a) is a front view and (b) is a side view. As shown in the drawing, the recess forming ring 30 is formed in an annular shape with an insertion hole 30a slightly larger than the diameter of the shaft foot 28 in the center of a circular plate. The outer diameter D2 on one side has a circular shape substantially equal to the outer diameter of the female screw cylinder 26, while the outer diameter D1 on the other side has a circular shape that is slightly larger than the outer diameter on the one side. That is, the peripheral surface of the recess forming ring 30 is tapered and the outer shape thereof is a truncated cone. The recess forming ring 30 is made of a resin, and reinforcing fibers such as carbon fibers are mixed in the resin to increase its rigidity and make it difficult to be crushed. Here, the recess forming ring 30 is configured so that the outer end surface of the female screw cylinder 26 is separated from the mold plate 22, so that the female screw cylinder is formed from the surface of the wall body 36 to be constructed as shown in FIG. 5B (VII). A recess 38 is formed by recessing the outer end face of 26, and as shown in (IIX) and (IX) of FIG. 5C, a plug 40 for covering the outer end face of the female screw cylinder 26 is mounted in the recess 38. It is provided as much as possible.

そして、コンクリート壁体36の構築に際しては、図5A〜図5Cに示す作業工程の手順によって型枠板22の組み立て、及びコンクリートの打設、型枠板22の解体を行う。即ち、先ず図5Aの(I)に示す工程では、セパレータ24の両軸端部に形成されている雄ねじ部24aに、それぞれ雌ねじ筒26を螺合させる(雌ねじ筒螺合工程)。爾後、同図の(II)に示す工程では、雌ねじ筒26に軸足28を螺合させて継ぎ足す(軸足28螺合工程)。   Then, when the concrete wall 36 is constructed, the formwork plate 22 is assembled, concrete is placed, and the formwork plate 22 is disassembled according to the procedure of the work steps shown in FIGS. 5A to 5C. That is, first, in the step shown in FIG. 5A (I), the female screw cylinders 26 are respectively screwed into the male screw portions 24a formed at both shaft end portions of the separator 24 (female screw cylinder screwing step). After the heel, in the step shown in (II) of the figure, the shaft foot 28 is screwed into the female screw cylinder 26 and added (shaft foot 28 screwing step).

次に、同図の(III)及び(IV)に示す工程では、左右の各軸足28の外周部に凹部形成用リング30をそれぞれ装着する。ここで、上記凹部形成用リング30は、小径に形成されている一側面側を雌ねじ筒26に向けて装着する。その後、当該両軸足28のそれぞれに型枠板22の挿通孔23を嵌め込んで当該型板枠22を係止させる(型枠板係止工程)。   Next, in the steps shown in (III) and (IV) of the figure, the recess forming rings 30 are respectively mounted on the outer peripheral portions of the left and right axle feet 28. Here, the recess forming ring 30 is mounted with one side surface formed in a small diameter directed toward the female screw cylinder 26. Thereafter, the insertion hole 23 of the mold plate 22 is fitted into each of the shaft feet 28 to lock the mold frame 22 (mold plate locking step).

次に、図5Bの(V)に示す工程では、各型枠板22から外方に突出する各軸足28の雄ねじ部28bの突出端にフォームタイ32を螺合させて、当該フォームタイ32と雌ねじ筒26との間に型枠板22と凹部形成用リング30とを締め付けて圧着固定し、一対の型枠板22,22を所定の間隔で並行に支持する(型枠板保持工程)。   Next, in the step shown in FIG. 5B (V), the foam tie 32 is screwed into the projecting end of the male thread portion 28b of each shaft foot 28 projecting outward from each mold plate 22, and the foam tie 32 is engaged. The mold plate 22 and the recess forming ring 30 are clamped and fixed between the inner screw cylinder 26 and the female screw cylinder 26 to support the pair of mold plates 22 and 22 in parallel at a predetermined interval (form plate holding step). .

そして、同様にして当該型枠板22に形成されている各所の挿通孔部に設けた全ての型枠保持具20を締め付けて型枠の組み立てが完了したならば、図5Bの(VI)の工程に示すように、当該型枠の両型枠板22間に区画形成されたコンクリート打設空間にコンクリート42を流し込んで打設する(コンクリート打設工程)。   Similarly, when the assembly of the formwork is completed by tightening all the formwork holders 20 provided in the insertion hole portions of the various places formed in the formwork plate 22, the (VI) of FIG. As shown in the process, the concrete 42 is poured into the concrete placement space defined between the two mold plates 22 of the mold and cast (concrete placement process).

そして、当該コンクリート42が硬化した後に、両型枠板22の外側のフォームタイ32 を緩めて軸足28 から離脱させ、硬化したコンクリート42の表面から一対の型枠板22及び凹部形成用リング30をそれぞれ取り外すとともに、一対の軸足28を緩めて雌ねじ筒26から離脱させて型枠を解体する(型枠解体工程)。   After the concrete 42 is hardened, the foam ties 32 outside the two mold plates 22 are loosened and detached from the shaft feet 28, and a pair of the mold plates 22 and the recess forming ring 30 are removed from the surface of the hardened concrete 42. And the pair of shaft legs 28 are loosened and separated from the female threaded cylinder 26 to dismantle the mold (mold dismantling process).

以上の工程により図5B(VII)に示すように、コンクリート42の内部にセパレータ24と雌ねじ筒26とが埋設されているコンクリート壁体36が構築される。また、このコンクリート壁体36の表面には、上記凹部形成用リング30によって、内部に埋設されている雌ねじ筒26の外側端面を露出させる凹部38が形成される。   As shown in FIG. 5B (VII), the concrete wall body 36 in which the separator 24 and the female screw cylinder 26 are embedded in the concrete 42 is constructed by the above steps. Further, a recess 38 is formed on the surface of the concrete wall 36 by the recess forming ring 30 to expose the outer end face of the internally threaded cylinder 26 embedded therein.

そして、図5Cの(IIX)と(IX)の工程とに示すように、その凹部形成用リング30によって形成された壁体表面の凹部38には、栓体40を嵌め込んで充填し、当該凹部38を栓体40で埋めて雌ねじ筒26の外側端面を覆って隠す(栓体充填工程)。   Then, as shown in the steps (IIX) and (IX) of FIG. 5C, the plug body 40 is fitted and filled into the recess 38 on the surface of the wall formed by the recess forming ring 30. The recess 38 is filled with the plug body 40 to cover and conceal the outer end surface of the female screw cylinder 26 (plug body filling step).

即ち、上述のようにして打設形成されるコンクリート壁体36の内部には、セパレータ24に形成された雄ねじ部24aの両軸端部に螺合接続された型枠保持具20の雌ねじ筒26が、セパレータ24と一体化されて埋設されているとともに、雌ねじ筒26の外側端面はコンクリート壁体36の表面よりも内方に位置して、当該コンクリート壁体36の表面には、雌ねじ筒26の外側端面を露出させる凹部38が形成されて、当該凹部38には、雌ねじ筒26の外側端面を被覆する栓体40が充填装着されている構造となっている。   That is, in the concrete wall body 36 formed and formed as described above, the female screw cylinder 26 of the mold holder 20 screwed and connected to both axial ends of the male screw portion 24a formed in the separator 24. However, the outer end face of the female screw cylinder 26 is positioned inward of the surface of the concrete wall 36, and the female screw cylinder 26 is disposed on the surface of the concrete wall 36. A recess 38 that exposes the outer end surface of the female screw cylinder 26 is formed, and the plug 38 that covers the outer end surface of the female screw cylinder 26 is filled in the recess 38.

従って、上述の如く構成されるコンクリート壁体36の構造にあっては、型枠保持具20の雌ねじ筒26は従来のようなコンクリート製のコーン部を有しておらず、セパレータ24とこれに螺合された雌ねじ筒26の周囲には打設したコンクリート42が回り込んで定着し一体化するので、構築後のコンクリート壁体36の外表面にはコーン部によるコンクリート色の異なる円形模様がその壁面の全体に多数生じてしまうことがなく、美観の向上を図ることができるようになる。   Therefore, in the structure of the concrete wall body 36 configured as described above, the female screw cylinder 26 of the mold holder 20 does not have a conventional concrete cone portion, and the separator 24 and Since the concrete 42 that has been placed wraps around the screwed female screw cylinder 26 and is fixed and integrated, a circular pattern having a different concrete color is formed on the outer surface of the concrete wall 36 after construction. A large number of wall surfaces do not occur, and the aesthetics can be improved.

また、雌ねじ筒26にコンクリート製のコーン部を設けないので、当該雌ねじ筒26の重量の軽減化と小型化とが図れ、もって当該雌ねじ筒26を部品として箱詰め梱包した場合にも、その総重量の可及的な軽減化と箱体の縮小化とが図れて、現場への搬入時等における可搬性を向上させることができる。さらに、その搬入時の振動等によって型枠保持具の雌ねじ筒26同士がぶつかり合っても、従来のようにコンクリート製コーン部の角に亀裂や割れが生じるような事が無く、雌ねじ筒26を損傷させてしまう虞がない。   Further, since the concrete threaded portion 26 is not provided with the concrete cone portion, the weight of the internally threaded tube 26 can be reduced and the size can be reduced. Can be reduced as much as possible and the box can be reduced, and the portability at the time of carrying in to the site can be improved. Further, even if the female screw cylinders 26 of the mold holder collide with each other due to vibrations at the time of carrying in, the corners of the concrete cone portion are not cracked or broken as in the conventional case, and the female screw cylinder 26 is There is no risk of damage.

《第2実施形態》
図6〜図8は本発明に係るコンクリート壁体の構築方法、及びその構築方法に用いる型枠保持具の第2実施形態を示すものである。ここで、当該第2実施形態の主たる構成は前述した第1実施形態とほぼ同一であり、その相違する部分は軸足28と凹部形成用リング30とにあり、その他の点では第1実施形態と一致する。よって、以下には当該相違点に付いて詳述し、第1実施形態と同一の部材には同一の符号を付してその詳しい説明は省略する。
<< Second Embodiment >>
6 to 8 show a concrete wall body construction method according to the present invention and a second embodiment of a mold holder used in the construction method. Here, the main configuration of the second embodiment is substantially the same as that of the first embodiment described above, and the different parts are the shaft foot 28 and the recess forming ring 30, and the first embodiment otherwise. Matches. Therefore, the difference will be described in detail below, and the same members as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

図7は第2実施形態にて用いられる軸足28を示しており、(a)は軸長方向から見た側面図、(b)はその正面図である。同図に示すように、軸足28にはその軸長方向のほぼ中央部に形成されている非ネジ部28cの外周部に、径方向外方に向けて突出する係止片28dが一体的に設けられている。ここで当該係止片28dの径方向外方への突出量は、型枠板22に尖設形成されている軸足用の挿通孔23の開口周縁に当接する大きさに設定されている。この図示例では、当該係止片28dは軸足28の外周に沿って環状に一体形成されており、その外径寸法は軸足用の挿通孔23の内径よりも若干大きくなっていて、雌ねじ筒26に螺合される有効ねじ長の短い一端側の雄ねじ部28aに隣接して設けられている。また、この軸足28には、フォームタイ32を螺合させるための有効ねじ長の長い他端側の雄ねじ部28bの先端外周部に、当該軸足28を雌ねじ筒26に脱着させる際に使用するレンチを係合させるための平行面28eが窪まされて形成されている。   FIG. 7 shows a shaft foot 28 used in the second embodiment, (a) is a side view seen from the axial length direction, and (b) is a front view thereof. As shown in the figure, the shaft foot 28 is integrally provided with a locking piece 28d protruding outward in the radial direction on the outer peripheral portion of the non-screw portion 28c formed at the substantially central portion in the axial length direction. Is provided. Here, the protruding amount of the locking piece 28d outward in the radial direction is set to a size that comes into contact with the peripheral edge of the insertion hole 23 for the shaft foot formed sharply on the mold plate 22. In this illustrated example, the locking piece 28d is integrally formed in an annular shape along the outer periphery of the shaft foot 28, and its outer diameter is slightly larger than the inner diameter of the insertion hole 23 for the shaft foot. It is provided adjacent to the male screw portion 28a on one end side with a short effective screw length to be screwed into the cylinder 26. Further, the shaft foot 28 is used when the shaft foot 28 is attached to and detached from the female screw cylinder 26 on the outer peripheral portion of the male screw portion 28b on the other end side having a long effective screw length for screwing the foam tie 32. A parallel surface 28e for engaging a wrench is depressed and formed.

一方、図8に示すように、凹部形成用リング30には上記軸足28の係止片28dを収納するための凹部30bが大径側の端面に形成されている。   On the other hand, as shown in FIG. 8, the recess forming ring 30 is formed with a recess 30b for accommodating the locking piece 28d of the shaft foot 28 on the end face on the large diameter side.

そして、当該第2実施形態の場合にあっても、そのコンクリート壁体の構築に際しては、図5A〜図5Cに示した前述の第1実施形態と同様の作業工程の手順によって型枠板22の組み立て、及びコンクリート42の打設、型枠板22の解体を行う。ここで、図6は第2実施形態における型枠保持具20を用いて、一対の型枠板22の一方を固定保持した状態を示す断面図であるが、同図に示すように、軸足28の係止片28dは型枠板22の軸足用の挿通孔23の内面側開口の周縁部に当接される。また、このとき当該係止片28dは凹部形成用リング30に形成された係止片用の凹部30b内に収容される。このため、凹部形成用リング30は型枠板22と雌ねじ筒26との間に圧接されて挟持され、型枠板22と離間してしまうことがない。   And even in the case of the said 2nd Embodiment, in the case of construction | assembly of the concrete wall body, according to the procedure of the work process similar to the above-mentioned 1st Embodiment shown to FIG. 5A-FIG. Assembly, placement of concrete 42, and dismantling of formwork plate 22. Here, FIG. 6 is a cross-sectional view showing a state in which one of the pair of mold plates 22 is fixedly held by using the mold holder 20 in the second embodiment. As shown in FIG. The 28 locking pieces 28 d are in contact with the peripheral edge of the opening on the inner surface side of the insertion hole 23 for the shaft foot of the mold plate 22. At this time, the locking piece 28d is accommodated in the locking piece recess 30b formed in the recess forming ring 30. For this reason, the recess forming ring 30 is pressed against and sandwiched between the mold plate 22 and the female screw cylinder 26 and is not separated from the mold plate 22.

そして、打設したコンクリートの硬化後に型枠板22を解体撤去するに際しては、タイフォーム32の取り外し後に、雌ねじ筒26に螺合している軸足28を緩めて取り外していくと、係止片28dが型枠板22に当接しているので、軸足と共に型枠板も一緒になって同時にコンクリート壁体36から離脱されていくことになる。このため、型枠の解体撤去作業が効率的に行えるようになる。   When the mold plate 22 is disassembled and removed after the cast concrete is hardened, after the tie foam 32 is removed, the shaft foot 28 screwed into the female screw cylinder 26 is loosened and removed. Since 28d is in contact with the formwork plate 22, the formwork plate together with the shaft foot is simultaneously removed from the concrete wall 36. For this reason, the work of dismantling and removing the formwork can be performed efficiently.

図9は第2実施形態の変形例を示すものである。即ち、当該変形例では、凹部形成用リング30を軸足28の係止片28dと型枠板22との間に挟んで挟持するように、軸足28の外周に装着しており、係止片28dが凹部形成用リング30の内面側に当接させて組み付けている。   FIG. 9 shows a modification of the second embodiment. That is, in this modification, the recess forming ring 30 is mounted on the outer periphery of the shaft foot 28 so as to be sandwiched between the locking piece 28d of the shaft foot 28 and the mold plate 22, The piece 28d is assembled in contact with the inner surface side of the recess forming ring 30.

このように組み付ければ、型枠板22を解体撤去するに際し、雌ねじ筒26に螺合している軸足28を緩めて取り外していくと、係止片28dが凹部形成用リング30に当接しているので、軸足と共に凹部形成用リング30と型枠板22とが一緒になって同時にコンクリート壁体36から離脱されていくことになる。このため、型枠の解体撤去作業が更に効率的に行えるようになる。   When assembled in this manner, when the mold plate 22 is disassembled and removed, if the shaft foot 28 screwed into the female screw cylinder 26 is loosened and removed, the locking piece 28d comes into contact with the recess forming ring 30. Therefore, the recess forming ring 30 and the formwork plate 22 together with the shaft foot are simultaneously detached from the concrete wall 36. For this reason, the work of dismantling and removing the formwork can be performed more efficiently.
