Description

本発明は、建物の基礎部分や地下部分を支えるコンクリート製の地中梁や、雨水等を貯留する貯留槽のコンクリート製の側壁を形成するための型枠に関する。更に詳しくは、地中梁や側壁の表面に残存する残存型枠に関するものである。   TECHNICAL FIELD The present invention relates to a concrete underground beam that supports a foundation portion and an underground portion of a building, and a formwork for forming a concrete sidewall of a storage tank that stores rainwater and the like. More specifically, the present invention relates to a residual formwork that remains on the surface of an underground beam or a side wall.

従来、地中に掘られた穴の底部に敷設されたコンクリート製の底盤と、この底盤上に設けられ上記穴内に収容された貯留複合体と、底盤上に貯留複合体を囲んで設けられたコンクリート製の四角筒状の側壁と、この側壁を四角枠状に形成するための側壁形成部材とを備えた貯留槽が開示されている(例えば、特許文献1(請求項1、請求項5、段落[0019]、[0023]、図1、図3〜図5)参照。)。この貯留槽では、貯留複合体が、下面に少なくとも1本の円筒リブが突設されかつ上面に少なくとも1本の円筒リブが突設された正方形板状の複数の仕切板と、この仕切板の下面又は上面のいずれか一方又は双方に円筒リブに嵌合して接続される筒状のスペーサと、貯留複合体の最も外側に仕切板及びスペーサを鉛直方向に交互に配置することにより設けられた最外層部とを有する。また、側壁形成部材が、最外層部を構成しかつ鉛直方向に間隔をあけて配設された複数段の仕切板の間の各段毎に最外層部を構成する複数のスペーサのうち最外層部の外面を形成する部分に接触するように複数の第1板材を配設することにより四角筒状に形成された複数段の内側型枠と、最外層部を構成し鉛直方向に間隔をあけて配設された複数段の仕切板に複数の第1板材より外方に位置するように挿通された複数の縦鉄筋と、最外層部を構成し鉛直方向に間隔をあけて配設された複数段の仕切板より外方に配設された複数の第2板材を複数のセパレータにより縦鉄筋から所定の間隔をあけて保持することにより四角筒状に形成された単一段の外側型枠とを有する。更に、第1板材がプラスチック段ボール材であり、第2板材がラス網である。   Conventionally, a concrete bottom plate laid at the bottom of a hole dug in the ground, a storage complex provided on the bottom plate and accommodated in the hole, and provided on the bottom plate surrounding the storage complex. There is disclosed a storage tank provided with a side wall of a concrete rectangular tube and a side wall forming member for forming the side wall into a rectangular frame shape (for example, Patent Document 1 (Claims 1, 5 and 5). See paragraphs [0019], [0023], FIG. 1, FIGS. 3-5)). In this storage tank, the storage composite comprises a plurality of square plate-shaped partition plates having at least one cylindrical rib projecting on the lower surface and at least one cylindrical rib projecting on the upper surface, and the partition plates. Provided by vertically arranging a cylindrical spacer, which is fitted and connected to a cylindrical rib on one or both of the lower surface and the upper surface, and a partition plate and a spacer on the outermost side of the storage complex in the vertical direction. And an outermost layer portion. Further, the side wall forming member constitutes the outermost layer portion, and among the plurality of spacers forming the outermost layer portion for each step between the plurality of partition plates arranged at intervals in the vertical direction, the outermost layer portion A plurality of steps of inner molds formed in a square tube shape by arranging a plurality of first plate members so as to come into contact with a portion forming an outer surface, and an outermost layer portion that are vertically spaced apart from each other. A plurality of vertical reinforcing bars that are inserted through a plurality of partition plates provided so as to be positioned outside the plurality of first plate members, and a plurality of stages that constitute the outermost layer portion and are arranged at intervals in the vertical direction. A plurality of second plate members arranged outside of the partition plate are held by a plurality of separators at predetermined intervals from the vertical reinforcing bars, and have a single-stage outer form frame formed in a square tube shape. . Further, the first plate member is a plastic corrugated cardboard member and the second plate member is a lath net.

このように構成された貯留槽では、内側型枠と外側型枠の間に生コンクリートを流込んで硬化させることにより、側壁を底盤の上面に形成することができ、貯留複合体の構築作業と、側壁形成部材の構築作業及び側壁形成作業とをほぼ同時に進行できる。この結果、コンクリート製の側壁を比較的簡便な方法で、熟練した作業者でなくても、比較的短時間に形成できる。また、貯留槽の外周面に土圧のうち比較的大きな水平方向の分圧が作用しても、構造的に強固なコンクリート製の側壁が上記分圧を受けるので、貯留複合体の損傷を防止できる。更に、コンクリート製の側壁が貯留槽内の貯留複合体により支持されるので、側壁の厚さを必要最小限に抑制できる。更に、第1板材として比較的軽量で比較的強度の高いプラスチック段ボール材を用い、第2板材として比較的軽量で比較的強度の高いラス網を用いたので、第1板材及び第2板材の搬送及び据付けを比較的容易に行うことができる。   In the storage tank configured in this manner, the side wall can be formed on the upper surface of the bottom plate by pouring ready-mixed concrete between the inner mold and the outer mold to cure it. The construction work of the side wall forming member and the side wall forming work can proceed substantially at the same time. As a result, the concrete side wall can be formed in a relatively short time by a relatively simple method even by an unskilled operator. Further, even if a relatively large horizontal partial pressure of earth pressure acts on the outer peripheral surface of the storage tank, the structurally strong concrete side wall receives the above partial pressure, preventing damage to the storage complex. it can. Further, since the concrete side wall is supported by the storage complex in the storage tank, the thickness of the side wall can be suppressed to the necessary minimum. Further, since the relatively light weight and relatively high strength plastic corrugated board material is used as the first plate material and the relatively light weight and relatively high strength lath net is used as the second plate material, the conveyance of the first and second plate materials is performed. And the installation can be performed relatively easily.

上記従来の特許文献1に示された貯留槽では、ラス網が変形し易く自立性がないため、このラス網を垂直に立てた状態でセパレータで保持するのに多くの工数を要する不具合があった。また、上記従来の特許文献1に示された貯留槽では、この貯留槽を全て地上に設置するか、或いは貯留槽の下部を地下に埋設しかつ上部を地上に露出させると、貯留槽の外周面の見栄えを損なう問題点もあった。   In the above-mentioned conventional storage tank disclosed in Patent Document 1, the lath net is easily deformed and does not have self-sustainability. Therefore, there is a problem that a large number of man-hours are required to hold the lath net in a vertical state with a separator. It was Further, in the conventional storage tank disclosed in Patent Document 1, if the storage tank is installed entirely on the ground, or if the lower part of the storage tank is buried underground and the upper part is exposed to the ground, the outer circumference of the storage tank is increased. There was also a problem that spoiled the appearance.

一方、レンガを積んで外側型枠を形成する方法があるけれども、この方法では、積み上げられたレンガがセパレータにより支えられておらず自立構造であるため、生コンクリートを内側型枠及び外側型枠間に一度に大量に流込むと、レンガ製の外側型枠が崩れてしまう。このため、生コンクリートを内側型枠及び外側型枠間に少し流し込んでは硬化させ再び少し流し込んでは硬化させるという作業を繰返さなければならない問題点があった。   On the other hand, although there is a method of stacking bricks to form an outer mold, in this method, since the stacked bricks are not supported by the separator and have a self-supporting structure, green concrete is used between the inner mold and the outer mold. If a large amount of it is poured at once, the brick outer formwork will collapse. For this reason, there has been a problem that the work of pouring fresh concrete between the inner and outer molds a little to cure it and then pouring it again a little to cure it has to be repeated.

When it is formed, the decorative plate having a pattern in which the pattern is convex or concave is exposed. As a result, the appearance of the surface of the side wall can be improved.

本発明の第3の観点の残存型枠では、側壁が、建物を支えるために地中に埋設されかつ底盤上に設けられるコンクリート製の地中梁であり、この地中梁の外面を外側型枠により形成し、地中梁の内面を内側型枠により形成したので、基板、中央部補強板及び端部補強板を縦横に結合することにより外側型枠及び内側型枠を形成し、内側型枠と外側型枠との間に複数の縦鉄筋を配設し、これらの縦鉄筋により外側型枠及び内側型枠を保持する。この結果、自立性を有しかつ強固な外側型枠及び内側型枠を容易に組立てることができる。また、内側型枠及び外側型枠間に生コンクリートを一度に大量に流し込んでも、外側型枠及び内側型枠が変形せずに、所定形状のコンクリート製の側壁を形成できる。   In the residual formwork of the third aspect of the present invention, the side wall is a concrete underground beam which is buried in the ground to support the building and is provided on the bottom plate, and the outer surface of the underground beam is an outside mold. Since it was formed by a frame and the inner surface of the underground beam was formed by an inner mold, the outer mold and the inner mold were formed by vertically and horizontally connecting the substrate, the central reinforcing plate and the end reinforcing plate, and the inner mold was formed. A plurality of vertical rebars are arranged between the frame and the outer mold, and these vertical rebars hold the outer mold and the inner mold. As a result, the self-supporting and strong outer and inner molds can be easily assembled. Further, even when a large amount of fresh concrete is poured at a time between the inner mold and the outer mold, the outer mold and the inner mold are not deformed, and the concrete side wall having a predetermined shape can be formed.

本発明の第4の観点の残存型枠では、側壁が、貯留槽を形成するために底盤上に直方体状の貯留複合体を囲んで設けられるコンクリート製の四角筒状の側壁であり、この側壁の外面を外側型枠により形成したので、基板、中央部補強板及び端部補強板を縦横に結合することにより外側型枠を形成し、内側型枠と外側型枠との間に複数の縦鉄筋を配設し、これらの縦鉄筋により外側型枠を保持する。この結果、自立性を有しかつ強固な外側型枠を容易に組立てることができる。なお、内側型枠は、底盤上に組立てられた貯留複合体の外周面に組付けられる。また、外側型枠としてラス網やレンガを用いた場合と比較して、外側型枠の組立作業を大幅に短縮できるとともに、内側型枠及び外側型枠間に生コンクリートを一度に大量に流し込んでも、外側型枠が変形せずに、所定形状のコンクリート製の側壁を形成できる。更に、貯留槽を全て地上に設置するか或いは貯留槽の下部を地中に埋没させかつ上部を地上に突出するように設置する場合、地上に突出する外側型枠の中央部補強板の表面に化粧板を取付ければ、貯留槽の表面の見栄えを向上できる。   In the residual formwork according to the fourth aspect of the present invention, the side wall is a concrete rectangular tubular side wall provided on the bottom plate so as to surround the rectangular parallelepiped storage complex to form a storage tank. Since the outer surface of the is formed by the outer mold, the outer mold is formed by vertically and horizontally connecting the substrate, the central reinforcing plate and the end reinforcing plate, and a plurality of vertical molds are formed between the inner mold and the outer mold. Reinforcing bars are arranged, and these vertical reinforcing bars hold the outer formwork. As a result, a self-supporting and strong outer formwork can be easily assembled. The inner formwork is assembled to the outer peripheral surface of the storage complex assembled on the bottom plate. Also, compared with the case of using lath net or brick as the outer formwork, the work of assembling the outer formwork can be significantly shortened, and even if a large amount of fresh concrete is poured at a time between the inner formwork and the outer formwork. It is possible to form a concrete side wall having a predetermined shape without the outer formwork being deformed. In addition, when installing all storage tanks on the ground, or when burying the lower part of the storage tank in the ground and installing the upper part so that it projects above the ground, on the surface of the central part reinforcing plate of the outer formwork projecting above the ground By attaching a decorative plate, the appearance of the surface of the storage tank can be improved.

The remaining formwork 13 includes an inner formwork 14 forming an inner surface of the underground girder 11, an outer formwork 16 forming an outer surface of the underground girder 11, and an inner formwork 14 and an outer formwork 16. A plurality of vertical rebars 17 are provided that hold the outer mold 16 and the inner mold 14.

上記外側型枠16と内側型枠14は、同一部品により面対称に形成される(図1)。外側型枠16及び内側型枠14は、プラスチックにより正方形板状に形成されかつ縦横に密着して並べられた複数の基板18と、基板18と略同大の正方形板状にプラスチックにより形成され隣り合う4枚の基板18を結合しかつ縦横に密着して並べられた複数の中央部補強板19と、プラスチックにより長方形板状に形成され縦横に密着して並べられた複数の中央部補強板19の外周縁に位置しかつ隣り合う基板18を結合して四角枠状に並べられた複数の端部補強板21とをそれぞれ有する(図1〜図4)。基板18、中央部補強板19及び端部補強板21は、ポリオレフィン樹脂(ポリプロピレン、ポリエチレン等)、塩化ビニル樹脂等により形成される。   The outer mold 16 and the inner mold 14 are formed symmetrically by the same part (FIG. 1). The outer mold 16 and the inner mold 14 are formed of plastic into a square plate shape and are arranged side by side in close contact with each other in the vertical and horizontal directions. A plurality of central portion reinforcing plates 19 which are formed by combining four matching substrates 18 and are arranged in close contact with each other vertically and horizontally, and a plurality of central portion reinforcing plates 19 which are formed of plastic into a rectangular plate and are arranged in close contact with each other vertically and horizontally. And a plurality of end reinforcing plates 21 arranged in a rectangular frame shape by joining adjacent substrates 18 to each other (FIGS. 1 to 4). The substrate 18, the central reinforcing plate 19 and the end reinforcing plate 21 are formed of a polyolefin resin (polypropylene, polyethylene or the like), a vinyl chloride resin or the like.

基板18は、一辺が20cm〜80cmでありかつ厚さが4cm〜8cmである正方形板状に形成されることが好ましい。また、基板18は、正方形板状に形成された基板本体18aと、この基板本体18aを4つの正方形板状に区画したときにこれらの区画された正方形板の略中央にそれぞれ形成された4つの基板結合孔18bと、基板本体18aの両面のうち中央部補強板19又は端部補強板21に向って突設され4つの基板結合孔18bの周囲をそれぞれ囲む4つの円筒リブ18cと、基板本体18aの両面のうち中央部補強板19又は端部補強板21に対向する面とは反対側に突設されかつ基板本体18aの外周縁に沿って延びる四角枠状に形成された枠状突起18dとを有する(図1及び図6)。また、基板18の外周面、即ち枠状突起18dの外面には、4つの辺の各辺毎に、基板18の厚さ方向に2列かつ基板の長手方向に4列の凹部18e及び凸部18fがそれぞれ交互に市松模様状(チェック模様状)に形成される(図6)。円筒リブ18cの高さは、後述の外側角部連結板22及び内側角部連結板(図示せず)の厚さと略同一に形成される。   The substrate 18 is preferably formed in a square plate shape having a side of 20 cm to 80 cm and a thickness of 4 cm to 8 cm. Further, the substrate 18 includes a substrate body 18a formed in a square plate shape, and four substrate bodies 18a formed in substantially the centers of the divided square plates when the substrate body 18a is divided into four square plate shapes. The board coupling hole 18b, four cylindrical ribs 18c projecting toward the central reinforcing plate 19 or the end reinforcing plate 21 on both sides of the board body 18a and surrounding the four board coupling holes 18b, respectively, and the board body. A frame-shaped projection 18d formed in the shape of a quadrangular frame projecting from the opposite side of the surface of the substrate 18a facing the central reinforcing plate 19 or the end reinforcing plate 21 and extending along the outer peripheral edge of the substrate body 18a. And (FIGS. 1 and 6). Further, on the outer peripheral surface of the substrate 18, that is, on the outer surface of the frame-shaped projection 18d, two rows of concave portions 18e and four convex portions are formed in each of the four sides in the thickness direction of the substrate 18 and in the longitudinal direction of the substrate. 18 f are alternately formed in a checkered pattern (check pattern) (FIG. 6). The height of the cylindrical rib 18c is formed to be substantially the same as the thickness of an outer corner connecting plate 22 and an inner corner connecting plate (not shown) described later.

そして、複数の基板18が同一鉛直面内で縦横に密着して並べられる(図2〜図4)。このとき基板18の枠状突起18dの外面に形成された凹部18e及び凸部18fが、隣りの基板18の枠状突起18dの外面に形成された凸部18f及び凹部18eにそれぞれ遊挿及び遊嵌される。これにより上記基板18及び上記隣りの基板18がこれらの接する面内で移動するのを阻止できる、即ち上記基板18及び上記隣りの基板18がそれらの長手方向及び厚さ方向に相対的に移動するのを阻止できるようになっている。また、基板18の枠状突起18dの外面に形成された凹部18e及び凸部18fが、上側又は下側の基板18の枠状突起18dの外面に形成された凸部18f及び凹部18eにそれぞれ遊挿及び遊嵌される。この場合も、上記基板18及び上記上側又は下側の基板18がこれらの接する面内で移動するのを阻止できるようになっている。   Then, the plurality of substrates 18 are arranged in close contact with each other vertically and horizontally within the same vertical plane (FIGS. 2 to 4). At this time, the concave portion 18e and the convex portion 18f formed on the outer surface of the frame-shaped protrusion 18d of the substrate 18 are loosely inserted into the convex portion 18f and the concave portion 18e formed on the outer surface of the frame-shaped protrusion 18d of the adjacent substrate 18, respectively. Be fitted. As a result, it is possible to prevent the substrate 18 and the adjacent substrate 18 from moving within their contact planes, that is, the substrate 18 and the adjacent substrate 18 relatively move in the longitudinal direction and the thickness direction thereof. It is possible to prevent it. In addition, the concave portion 18e and the convex portion 18f formed on the outer surface of the frame-shaped protrusion 18d of the substrate 18 are respectively engaged with the convex portion 18f and the concave portion 18e formed on the outer surface of the frame-shaped protrusion 18d of the upper or lower substrate 18, respectively. It is inserted and loosely fitted. Also in this case, it is possible to prevent the substrate 18 and the upper or lower substrate 18 from moving in the contact planes thereof.

図1及び図6(b)中の符号18gは、枠状突起18d内に水平方向に延びて設けられた水平補強リブであり、図6(b)中の符号18hは、枠状突起18d内に鉛直方向に延びて設けられた鉛直補強リブである。この実施の形態では、水平補強リブ18gと、基板18の枠状突起18dの4辺のうち上下2辺には、所定の間隔をあけて複数の係止孔18iが形成される。そして、後述の外側セパレータ24の一端が縦鉄筋17の外側縦鉄筋17aに係止しかつ他端が外側型枠16を形成する基板18の係止孔18iに係止し、後述の内側セパレータ26の一端が縦鉄筋17の内側縦鉄筋17bに係止しかつ他端が内側型枠14を形成する基板18の係止孔18iに係止するように構成される。なお、水平補強リブ及び鉛直補強リブに係止孔を設け、枠状突起の4辺全てに係止孔を設けてもよい。この場合、基板の上下左右の区別がなくなり、基板の施工作業が容易になる。   Reference numeral 18g in FIGS. 1 and 6 (b) is a horizontal reinforcing rib provided in the frame-shaped projection 18d so as to extend in the horizontal direction, and reference numeral 18h in FIG. 6 (b) is inside the frame-shaped projection 18d. The vertical reinforcing ribs are provided to extend in the vertical direction. In this embodiment, a plurality of locking holes 18i are formed at predetermined intervals on the upper and lower two sides of the horizontal reinforcing rib 18g and the frame-shaped protrusion 18d of the substrate 18. Then, one end of the outer separator 24 described later is locked to the outer vertical reinforcing bar 17a of the vertical reinforcing bar 17 and the other end is locked to the locking hole 18i of the substrate 18 forming the outer form frame 16, and the inner separator 26 described later is One end is locked to the inner vertical reinforcing bar 17b of the vertical reinforcing bar 17 and the other end is locked to the locking hole 18i of the substrate 18 forming the inner formwork 14. The horizontal reinforcing ribs and the vertical reinforcing ribs may be provided with locking holes, and the locking holes may be provided on all four sides of the frame-shaped projection. In this case, there is no need to distinguish the top, bottom, left, and right of the substrate, and the work for constructing the substrate becomes easy.

中央部補強板19は、一辺が20cm〜80cmでありかつ厚さが3cm〜6cmである正方形板状に形成されることが好ましい(図1及び図7)。また、中央部補強板19は、正方形板状に形成された中央部補強板本体19aと、中央部補強板本体19aの両面のうち基板18に向って突設された4本の中央結合ピン19bと、中央部補強板本体19aの両面のうち基板18に対向する面とは反対側の面の中央に形成された正方形状の化粧板収容凹部19cとを有する。また、4本の中央結合ピン19bは、中央部補強板本体19aを4つの正方形板状に区画したときにこれらの区画された正方形板の略中央にそれぞれ形成される。これにより、縦横に隣接する4枚の基板18を密着して並べた状態で(図2)、中央部補強板19が4枚の基板18の中央に位置しかつ4枚の基板18の一隅に重なるように、中央部補強板19の4本の中央結合ピンを4枚の基板の基板結合孔18bにそれぞれ挿入することにより、4枚の基板18が中央部補強板19により結合される(図2(b)及び図3(a))。ここで、中央結合ピン19bは基板結合孔18bに圧入又は打込まれて、振動等により容易に抜けないように構成される。なお、図7(b)中の符号19dは、中央部補強板本体19aの両面のうち基板18に対向する面に形成された軽量化凹部であり、符号19eは、軽量化凹部19d内に縦横に突設された補強リブである。また、図2(b)、図3、図4及び図7中の符号19fは、化粧板34を取付けるための4つの透孔である。更に、中央部補強板19の外周面には、基板18の外周面、即ち枠状突起18dの外周面に形成された市松模様状(チェック模様状)の凹部及び凸部は形成されない。   The center reinforcing plate 19 is preferably formed in a square plate shape having a side of 20 cm to 80 cm and a thickness of 3 cm to 6 cm (FIGS. 1 and 7). The central reinforcing plate 19 includes a central reinforcing plate body 19a formed in a square plate shape and four central connecting pins 19b projecting toward the substrate 18 on both surfaces of the central reinforcing plate body 19a. And a square-shaped decorative plate accommodating recess 19c formed at the center of the surface of the central reinforcing plate body 19a opposite to the surface facing the substrate 18. Further, the four central coupling pins 19b are respectively formed at substantially the centers of the divided square plates when the central reinforcing plate body 19a is divided into four square plate shapes. As a result, the central reinforcing plate 19 is located at the center of the four substrates 18 and is located at one corner of the four substrates 18 in a state where the four substrates 18 that are vertically and horizontally adjacent to each other are closely arranged (FIG. 2). By inserting the four central coupling pins of the central reinforcing plate 19 into the substrate coupling holes 18b of the four substrates so that they overlap, the four substrates 18 are coupled by the central reinforcing plate 19 (Fig. 2 (b) and FIG. 3 (a)). Here, the central coupling pin 19b is press-fitted or driven into the substrate coupling hole 18b so as not to come off easily due to vibration or the like. Note that reference numeral 19d in FIG. 7B is a weight-reducing recess formed on one of the two surfaces of the central reinforcing plate body 19a that faces the substrate 18, and reference numeral 19e is in the weight-recessing recess 19d. It is a reinforcing rib projecting on. Reference numerals 19f in FIGS. 2B, 3, 4, and 7 are four through holes for attaching the decorative plate 34. Furthermore, on the outer peripheral surface of the central portion reinforcing plate 19, the checkered concave portions and convex portions formed on the outer peripheral surface of the substrate 18, that is, the outer peripheral surface of the frame-shaped protrusion 18d are not formed.

一方、端部補強板21は、長辺が中央部補強板19の1.5倍の長さを有し短辺が中央部補強板19の0.5倍の長さを有しかつ厚さが中央部補強板19の厚さと同一である長方形板状に形成される(図1、図3、図4及び図8)。また、端部補強板21は、長方形板状に形成された端部補強板本体21aと、端部補強板本体21aの両面のうち基板18に向って突設された3本の端部結合ピン21bとを有する(図1、図5及び図8(b))。また、3本の端部結合ピン21bは、端部補強板本体21aをその短辺を一辺とする正方形板状に区画したときにこれらの区画された正方形板の略中央にそれぞれ形成される。これにより、1枚の中央部補強板19により4枚の基板18を結合した状態で、1枚の端部補強板21が1枚の中央部補強板19の外周縁に位置するように、端部補強板21の3本の端部結合ピン21bのうち2本の端部結合ピン21bを1枚の基板18の基板結合孔18bにそれぞれ挿入しかつ残りの1本の端部結合ピン21bをこの基板18の隣りの基板18の基板結合孔18bに挿入することにより、1枚の端部補強板21が2枚の基板18にわたって重なった状態で2枚の基板18を結合するように構成される(図3(a))。上記と同様の作業を繰返すことにより、3枚の端部補強板が1枚の中央部補強板の外周縁に位置しかつ隣り合う基板を結合して四角枠状に並べられる(図3(b))。この実施の形態では、図4に示すように、複数の端部補強板21が、互いに密着して水平方向に延びる複数の中央部補強板19の外周縁に位置しかつ隣り合う基板18を結合して四角枠状に並べられる。ここで、端部結合ピン21bは基板結合孔18bに圧入又は打込まれて、振動等により容易に抜けないように構成される。   On the other hand, the end reinforcing plate 21 has a long side 1.5 times as long as the central reinforcing plate 19 and a short side 0.5 times as long as the central reinforcing plate 19 and has a thickness. Is formed in a rectangular plate shape having the same thickness as the central reinforcing plate 19 (FIGS. 1, 3, 4, and 8). The end reinforcing plate 21 includes an end reinforcing plate main body 21a formed in a rectangular plate shape, and three end connecting pins protruding toward the substrate 18 on both sides of the end reinforcing plate main body 21a. 21b (FIGS. 1, 5 and 8B). Further, when the end reinforcing plate body 21a is divided into a square plate shape having one short side thereof, the three end coupling pins 21b are respectively formed substantially at the centers of the divided square plates. Accordingly, in a state in which the four substrates 18 are joined by the one central reinforcing plate 19, one end reinforcing plate 21 is positioned at the outer peripheral edge of the one central reinforcing plate 19, Of the three end coupling pins 21b of the part reinforcing plate 21, two end coupling pins 21b are respectively inserted into the substrate coupling holes 18b of one substrate 18 and the remaining one end coupling pin 21b is inserted. By inserting the substrate 18 into the substrate coupling hole 18b of the substrate 18 adjacent to the substrate 18, the one end reinforcing plate 21 is configured to couple the two substrates 18 in a state of being overlapped with each other. (FIG. 3 (a)). By repeating the same operation as the above, the three end reinforcing plates are located on the outer peripheral edge of one central reinforcing plate, and adjacent substrates are joined to be arranged in a rectangular frame shape (FIG. 3B. )). In this embodiment, as shown in FIG. 4, a plurality of end reinforcing plates 21 are located at the outer peripheral edges of a plurality of central reinforcing plates 19 that are in close contact with each other and extend in the horizontal direction, and join adjacent substrates 18 together. Then, they are arranged in a square frame shape. Here, the end coupling pin 21b is press-fitted or driven into the substrate coupling hole 18b so as not to easily come off due to vibration or the like.

なお、図8(a)中の符号21cは、端部補強板本体21aの一対の短辺のうち一方の短辺に突設された係合凸条であり、符号21dは、端部補強板本体21aの一対の短辺のうち他方の短辺に凹設された短辺側係合凹条である。また、図8中の符号21eは、端部補強板本体21aの一対の長辺の両端部にそれぞれ形成された長辺側係合凹条である。上記係合凸条21cが短辺側係合凹条21d又は長辺側結合凹条21eに係合することにより、端部補強板21,21同士の厚さ方向への移動が阻止されるようになっている。更に、図8(b)中の符号21fは、端部補強板本体21aの両面のうち基板18に対向する面に形成された軽量化凹部であり、符号21gは、端部補強板本体21aの両面のうち基板18に対向する面とは反対側の面に長手方向に形成された複数の軽量化凹部である。   It should be noted that reference numeral 21c in FIG. 8 (a) is an engaging ridge protruding from one of the pair of short sides of the end reinforcing plate body 21a, and reference numeral 21d is an end reinforcing plate. It is a short side engaging groove provided on the other short side of the pair of short sides of the main body 21a. In addition, reference numeral 21e in FIG. 8 is a long side engaging groove formed on both ends of the pair of long sides of the end reinforcing plate body 21a. By engaging the engaging convex strip 21c with the short side engaging concave strip 21d or the long side connecting concave strip 21e, it is possible to prevent the end reinforcing plates 21 and 21 from moving in the thickness direction. It has become.

このように構成された地中梁11の組立手順を説明する。先ず、地中に底盤12より広い底部を有する穴を掘り、この穴の底部に四角枠状に鉄筋組立体33を置く。次いで、上記穴の底部に生コンクリートを流し込んで、穴の底部にコンクリート製の四角板状の底盤12を形成する。このとき、鉄筋組立体33の下部は底盤12中に埋設される。次に、底盤12上で、基板18、中央部補強板19及び端部補強板21を図1〜図4に示すように縦横に結合することにより外側型枠16を形成し、基板18、中央部補強板19及び端部補強板21を図1〜図4に示すように縦横に結合することにより内側型枠14を形成する。そして、外側型枠16を鉄筋組立体33の外方に所定の間隔をあけて位置させ、外側セパレータ24の一端を外側格子鉄筋28の外側横鉄筋27に係止しかつ外側セパレータ24の他端を外側型枠16の基板18の係止孔18iに係止する(図1)。これにより外側型枠16が複数の外側セパレータ24及び複数の外側横鉄筋27を介して複数の外側縦鉄筋17aにより保持される。また、内側型枠14を鉄筋組立体33の内方に所定の間隔をあけて位置させ、内側セパレータ26の一端を内側格子鉄筋31の内側横鉄筋29に係止しかつ内側セパレータ26の他端を内側型枠14の基板18の係止孔18iに係止する。これにより内側型枠14が複数の内側セパレータ26及び複数の内側横鉄筋29を介して複数の内側縦鉄筋17bにより保持される。   An assembling procedure of the underground beam 11 configured as above will be described. First, a hole having a bottom portion wider than the bottom plate 12 is dug in the ground, and the reinforcing bar assembly 33 is placed in a rectangular frame shape at the bottom portion of the hole. Then, fresh concrete is poured into the bottom of the hole to form a square plate-shaped bottom plate 12 made of concrete at the bottom of the hole. At this time, the lower portion of the reinforcing bar assembly 33 is embedded in the bottom plate 12. Next, on the bottom plate 12, the substrate 18, the central reinforcing plate 19, and the end reinforcing plate 21 are joined vertically and horizontally as shown in FIGS. The inner formwork 14 is formed by vertically and horizontally coupling the part reinforcing plate 19 and the end reinforcing plate 21 as shown in FIGS. Then, the outer formwork 16 is positioned outside the rebar assembly 33 with a predetermined space, one end of the outer separator 24 is locked to the outer horizontal rebar 27 of the outer grid rebar 28, and the other end of the outer separator 24 is located. Is locked in the locking hole 18i of the substrate 18 of the outer mold 16 (FIG. 1). As a result, the outer formwork 16 is held by the plurality of outer vertical reinforcing bars 17a via the plurality of outer separators 24 and the plurality of outer lateral reinforcing bars 27. Further, the inner formwork 14 is positioned inside the rebar assembly 33 with a predetermined space, one end of the inner separator 26 is locked to the inner horizontal rebar 29 of the inner grid rebar 31, and the other end of the inner separator 26 is located. Is locked in the locking hole 18i of the substrate 18 of the inner mold 14. Thereby, the inner formwork 14 is held by the plurality of inner vertical rebars 17b via the plurality of inner separators 26 and the plurality of inner horizontal rebars 29.

次に、図5に示すように、互いに直角に突き当たる外側型枠16,16同士を外側角部連結板22により連結し、互いに直角に突き当たる内側型枠14,14同士を内側角部連結板により連結する。このように組立てられた残存型枠13では、ラス網及びベニヤ板等を用いて外側型枠及び内側型枠を形成する場合と比較して、外側型枠16及び内側型枠14の組立作業を大幅に短縮できる。即ち、自立性を有しかつ強固な外側型枠16及び内側型枠14を容易に組立てることができる。更に、内側型枠14と外側型枠16の間に生コンクリートを流し込んで硬化させて地中梁11を形成する(図1)。このとき、内側型枠14及び外側型枠16間に生コンクリートを一度に大量に流し込んでも、外側縦鉄筋17aが外側セパレータ24を介して外側型枠16を保持し、内側縦鉄筋17bが内側セパレータ26を介して内側型枠14を保持するので、外側型枠16及び内側型枠14が変形せずに、所定形状のコンクリート製の地中梁11を形成できる。また、基板18、中央部補強板19及び端部補強板21をプラスチックにより形成したので、外側型枠16及び内側型枠14を構成する基板18、中央部補強板19及び端部補強板21を容易に作製できる。更に、廃プラスチックを用いて基板18、中央部補強板19及び端部補強板21を形成すれば、外側型枠16及び内側型枠14を構成する基板18、中央部補強板19及び端部補強板21を安価に作製できる。   Next, as shown in FIG. 5, the outer mold forms 16, 16 that abut each other at right angles are connected by the outer corner connecting plates 22, and the inner mold forms 14, 14 that abut each other at a right angle by the inner corner connecting plates. connect. In the remaining formwork 13 assembled in this way, the assembling work of the outer formwork 16 and the inner formwork 14 can be performed significantly as compared with the case where the outer formwork and the inner formwork are formed by using a lath net and a veneer plate. Can be shortened to That is, the outer mold 16 and the inner mold 14 which are self-supporting and strong can be easily assembled. Further, ready-mixed concrete is poured between the inner mold 14 and the outer mold 16 and cured to form the underground beam 11 (FIG. 1). At this time, even if a large amount of green concrete is poured at a time between the inner formwork 14 and the outer formwork 16, the outer vertical rebar 17a holds the outer formwork 16 via the outer separator 24, and the inner vertical rebar 17b holds the inner separator. Since the inner mold 14 is held via 26, the concrete underground beam 11 having a predetermined shape can be formed without the outer mold 16 and the inner mold 14 being deformed. Further, since the substrate 18, the central reinforcing plate 19 and the end reinforcing plate 21 are made of plastic, the substrate 18, the central reinforcing plate 19 and the end reinforcing plate 21 that form the outer mold 16 and the inner mold 14 are Easy to make. Further, if the substrate 18, the central reinforcing plate 19 and the end reinforcing plate 21 are formed by using waste plastic, the substrate 18, the central reinforcing plate 19 and the end reinforcing plate constituting the outer mold 16 and the inner mold 14 are formed. The plate 21 can be manufactured at low cost.

一方、残存型枠53の内側型枠54は、複数の内側板54aを配設することにより四角筒状に形成され、外側型枠56は、第1の実施の形態の外側型枠と同形同大に形成される。また、縦鉄筋57は、最外層部67を構成しかつ第1〜第4水平連結体61〜64の各仕切板58に内側型枠54より外方に位置するように仕切板58に形成された透孔(図示せず)に挿通される外側縦鉄筋57aを有する。更に、外側セパレータ24の一端は外側縦鉄筋57aとともに外側格子鉄筋28を形成する外側横鉄筋27に係止し、他端は外側型枠56の基板18の係止孔18iに係止することにより、外側型枠56は外側セパレータ24及び外側横鉄筋27を介して外側縦鉄筋57aにより保持される。上記内側型枠54は、最外層部67を構成しかつ鉛直方向に間隔をあけて配設された第1〜第4水平連結体61〜64の各段毎に、最外層部67を構成する複数のスペーサ66のうち最外層部67の外面を形成する部分に接触するように、即ち最外層部67を構成する複数のスペーサ66の全てを囲んだ状態でそれらの外面に線接触するように、内側板54aを配設することにより四角筒状に形成される(図10及び図11)。上記内側板54aは、比較的軽量で比較的強度の高いポリプロピレン製のプラスチック段ボールにより形成されることが好ましく、互いに隣接する内側板54aは、一部がオーバラップして配設される(図11)。ここで、最外層部67を構成するスペーサ66とともに内側型枠54を受ける複数の補助受け部材72が、最外層部67を構成する仕切板58の流通孔58fに挿通されることが好ましい。この補助受け部材72は塩化ビニル製の管により形成されることが好ましい。なお、この実施の形態では、第1の実施の形態の内側縦鉄筋、内側横鉄筋、内側格子鉄筋、内側セパレータ、鉄筋仮組体及び鉄筋組立体は用いられないけれども、縦横に延びる鉄筋を溶接して形成された格子状の補強用鉄筋(図示せず)により、貯留複合体55の外周面と外側格子鉄筋28(複数の外側縦鉄筋57a及び複数の外側横鉄筋27)が覆われる。   On the other hand, the inner mold 54 of the remaining mold 53 is formed in a rectangular tube shape by disposing a plurality of inner plates 54a, and the outer mold 56 has the same shape as the outer mold of the first embodiment. Formed to the same size. Further, the vertical reinforcing bars 57 form the outermost layer portion 67 and are formed on the partition plates 58 of the partition plates 58 of the first to fourth horizontal connecting bodies 61 to 64 so as to be positioned outside the inner mold 54. The outer vertical reinforcing bar 57a is inserted through the through hole (not shown). Further, one end of the outer separator 24 is locked to the outer horizontal reinforcing bar 27 forming the outer lattice reinforcing bar 28 together with the outer vertical reinforcing bar 57a, and the other end is locked to the locking hole 18i of the substrate 18 of the outer form frame 56. The outer mold 56 is held by the outer vertical rebars 57 a via the outer separator 24 and the outer horizontal rebars 27. The inner mold 54 constitutes the outermost layer portion 67, and constitutes the outermost layer portion 67 for each stage of the first to fourth horizontal connecting bodies 61 to 64 arranged at intervals in the vertical direction. In order to make contact with a portion of the plurality of spacers 66 that forms the outer surface of the outermost layer portion 67, that is, to make line contact with the outer surfaces of all of the plurality of spacers 66 that form the outermost layer portion 67. By arranging the inner plate 54a, the inner plate 54a is formed into a square tubular shape (FIGS. 10 and 11). The inner plates 54a are preferably made of a relatively light and relatively strong polypropylene plastic cardboard, and the inner plates 54a adjacent to each other are partially overlapped (FIG. 11). ). Here, it is preferable that a plurality of auxiliary receiving members 72 that receive the inner mold 54 together with the spacers 66 forming the outermost layer portion 67 are inserted into the flow holes 58f of the partition plate 58 forming the outermost layer portion 67.

In this embodiment, the inner longitudinal reinforcing bar, the inner transverse reinforcing bar, the inner lattice reinforcing bar, the inner lattice reinforcing bar, the inner separator, the temporary reinforcing bar assembly and the reinforcing bar assembly of the first embodiment are not used, but the reinforcing bars extending vertically and horizontally are welded. The outer peripheral surface of the storage complex 55 and the outer grid reinforcing bars 28 (the plurality of outer vertical reinforcing bars 57a and the plurality of outer lateral reinforcing bars 27) are covered with the grid-shaped reinforcing reinforcing bars (not shown) formed in this way.

なお、図11中の符号19gは、外側型枠56の中央部補強板本体19の両面のうち基板18に対向する面とは反対側の面の四隅にそれぞれ形成された4つの切欠状凹部である。これらの切欠状凹部19gの中央には、補強板連結孔19hがそれぞれ形成される。そして、4枚の中央部補強板19を縦横に密着して並べたときに、これらの中央部補強板19の中央に4つの切欠状凹部19gが合体してを正方形板状の連結板(図示せず)を収容可能な連結板収容凹部19iが形成される。上記連結板の裏面には4本の補強板連結ピン(図示せず)が突設され、これらの補強板連結ピンを4枚の中央部補強板19の補強板連結孔19hにそれぞれ挿入することにより、4枚の中央部補強板19が連結される。ここで、補強板連結ピンは補強板連結孔19hに圧入又は打込まれて、振動等により容易に抜けないように構成される。   Note that reference numeral 19g in FIG. 11 denotes four notched concave portions formed at four corners of both surfaces of the central reinforcing plate main body 19 of the outer mold frame 56 opposite to the surface facing the substrate 18. is there. Reinforcing plate connecting holes 19h are formed at the centers of these notched recesses 19g. When the four central reinforcing plates 19 are arranged in close contact with each other in the vertical and horizontal directions, four notched concave portions 19g are combined at the center of the central reinforcing plates 19 to form a square plate-like connecting plate (Fig. A connection plate accommodating recess 19i capable of accommodating (not shown) is formed. Four reinforcing plate connecting pins (not shown) are provided on the back surface of the connecting plate, and these reinforcing plate connecting pins are inserted into the reinforcing plate connecting holes 19h of the four central reinforcing plates 19, respectively. Thus, the four central reinforcing plates 19 are connected. Here, the reinforcing plate connecting pin is configured to be press-fitted or driven into the reinforcing plate connecting hole 19h so as not to come off easily due to vibration or the like.

一方、鉛直方向に延びる主軸パイプ68が、最外層部67及び内側外層部69を構成する仕切板58及びスペーサ66を貫通して設けられる(図10及び図11)。また、主軸パイプ68の外周面には所定の間隔をあけて主軸パイプ68の長手方向に延びる複数の長孔68aが空気溜まりの発生を防止するために形成される(図10)。更に、主軸パイプ68は、貯留槽50の底面から上面まで延びて設けられる(図13)。なお、貯留槽が比較的小型であり、比較的小さい強度しか要求されない場合には、主軸パイプを省略してもよい。   On the other hand, a spindle pipe 68 extending in the vertical direction is provided so as to penetrate through the partition plate 58 and the spacer 66 that form the outermost layer portion 67 and the inner outer layer portion 69 (FIGS. 10 and 11). Further, a plurality of elongated holes 68a extending in the longitudinal direction of the main spindle pipe 68 are formed on the outer peripheral surface of the main spindle pipe 68 at predetermined intervals in order to prevent air accumulation (FIG. 10). Further, the spindle pipe 68 is provided so as to extend from the bottom surface to the top surface of the storage tank 50 (FIG. 13). If the storage tank is relatively small and only a relatively small strength is required, the spindle pipe may be omitted.

内側外層部69より内側に位置しかつ第1〜第4水平連結体61〜64のうち最下段の第1水平連結体61及び下から3段目の第3水平連結体63を構成する仕切板58は、スペーサ66より長く形成されかつ鉛直方向に延びる長尺スペーサ73及び連結アダプタ74により連結される(図11及び図13)。また、連結アダプタ74は、4つの仕切板58を同一平面上で1つに結束する結束部材75と、この結束部材75と長尺スペーサ73とを連結させる漏斗状の漏斗部材76とを有する。最下段の第1水平連結体61の下面には正方形板状の底板77が敷き詰められ、最上段の第4水平連結体64の上面には正方形板状の天板78が被せられる(図13)。更に、天板78の上面は遮水シート79で覆われる。これにより貯水槽50内に泥水の浸入が阻止される。   A partition plate that is located inside the inner outer layer portion 69 and that constitutes the first horizontal connecting body 61 at the bottom of the first to fourth horizontal connecting bodies 61 to 64 and the third horizontal connecting body 63 at the third stage from the bottom. 58 is connected by a long spacer 73 and a connection adapter 74 which are formed longer than the spacer 66 and extend in the vertical direction (FIGS. 11 and 13). Further, the connection adapter 74 has a binding member 75 that binds the four partition plates 58 into one on the same plane, and a funnel-shaped funnel member 76 that connects the binding member 75 and the long spacer 73. A square plate-shaped bottom plate 77 is spread over the lower surface of the lowermost first horizontal connecting body 61, and a square plate-shaped top plate 78 is covered on the upper surface of the uppermost fourth horizontal connecting body 64 (FIG. 13). . Furthermore, the upper surface of the top plate 78 is covered with a water-blocking sheet 79. This prevents the infiltration of muddy water into the water tank 50.

一方、貯留槽50には雨水導入管81の先端が挿入される(図13)。この雨水導入管81の基端は貯留槽50より高い位置の地中に埋設された除塵管理枡82に接続され、この除塵管理枡82は雨水流入管83を介して横断面略U字状の側溝84に接続される。上記除塵管理枡82は、上部側面が雨水流入管83を介して側溝84に接続された第1枡91と、第1枡91に隣接して設けられた第2枡92と有する。第1枡91の鉛直方向の中央には、上面が次第に下る方向に傾斜する中底壁91aが設けられる。また、第1枡91の底部中央には、直立管91bが中底壁91aを貫通して立設され、この直立管91bの上端は中底壁91aの上面と略同じ方向に傾斜して形成される。更に、直立管91bの下部側面には雨水導入管81の基端が接続される。一方、第1枡91及び第2枡92の互いに接する側面には、小雨時に中底壁91a上を流下する少量の雨水を第2枡92内に導く比較的小さい流出孔91c及び流入孔92aがそれぞれ形成される。   On the other hand, the tip of the rainwater introduction pipe 81 is inserted into the storage tank 50 (FIG. 13). The base end of the rainwater introduction pipe 81 is connected to a dust removal control box 82 buried in the ground at a position higher than the storage tank 50. The dust removal control box 82 has a U-shaped cross section through a rainwater inflow pipe 83. It is connected to the gutter 84. The dust removal control box 82 has a first cell 91 having an upper side surface connected to the gutter 84 via the rainwater inflow pipe 83, and a second cell 92 provided adjacent to the first cell 91. A central bottom wall 91a, whose upper surface is inclined downward, is provided at the center of the first square 91 in the vertical direction. Further, an upright pipe 91b is erected at the center of the bottom of the first square 91 so as to pass through the middle bottom wall 91a, and the upper end of the upright pipe 91b is formed to be inclined in substantially the same direction as the upper surface of the middle bottom wall 91a. To be done. Further, the base end of the rainwater introduction pipe 81 is connected to the lower side surface of the upright pipe 91b. On the other hand, relatively small outflow holes 91c and inflow holes 92a for guiding a small amount of rainwater flowing down on the insole wall 91a into the second cell 92 during light rain are provided on the side surfaces of the first cell 91 and the second cell 92 which are in contact with each other. Formed respectively.

このように構成された貯留槽50の組立手順を説明する。先ず、地中に底盤52より広い底部を有する穴59を掘り、この穴59の底部にコンクリート製の底盤52を敷設する(図13)。次に、正方形板状の複数の仕切板58、筒状のスペーサ66、第1結合片71、第2結合片、主軸パイプ68等を用意し、底盤52上に貯留複合体55を構築して、この貯留複合体55を上記穴59内に収容する。このとき、底盤52上に貯留複合体55の最外層部67を先ず構築し、その後、貯留複合体55の内部を構築するが、この貯留複合体55の内部の構築と同時に、残存型枠53を構築する。   A procedure for assembling the storage tank 50 configured as above will be described. First, a hole 59 having a bottom portion wider than the bottom plate 52 is dug in the ground, and a concrete bottom plate 52 is laid at the bottom of the hole 59 (FIG. 13). Next, a plurality of square plate-shaped partition plates 58, a cylindrical spacer 66, a first coupling piece 71, a second coupling piece, a spindle pipe 68, etc. are prepared, and the storage complex 55 is constructed on the bottom plate 52. The storage complex 55 is housed in the hole 59. At this time, the outermost layer portion 67 of the storage complex 55 is first constructed on the bottom plate 52, and then the inside of the storage complex 55 is constructed. To build.

上記残存型枠の構築手順を図10に基づいて説明する。先ず、最外層部67を構成する仕切板58の最外層部67の外面に沿う流通孔58fに補助受け部材72を挿通する。次いで、4段の仕切板58の間の各段毎に最外層部67を構成する複数のスペーサ66のうち最外層部67の外面を形成する部分に接触するように複数の内側板54aを配設することにより3段の内側型枠54をそれぞれ四角筒状に形成する。そして、最外層部67を構成し鉛直方向に間隔をあけて配設された複数段の仕切板58の最外層部67の外面に沿う透孔に複数の外側縦鉄筋57aを複数の内側板54aより外方に位置するように鉛直方向に延びて挿通した後、水平方向に延びる外側横鉄筋27を外側縦鉄筋57aと交差させてその交差部を結束線(図示せず)で固定して、外側格子鉄筋28を形成する。次に、内側型枠54と外側型枠56の間の底盤52上に水膨張性のある止水材(図示せず)を配設した後に、格子状の補強用鉄筋(図示せず)により貯留複合体55の外周面と外側格子鉄筋28(複数の外側縦鉄筋57a及び複数の外側横鉄筋27)を覆う。   The procedure for constructing the remaining mold will be described with reference to FIG. First, the auxiliary receiving member 72 is inserted into the flow hole 58f along the outer surface of the outermost layer portion 67 of the partition plate 58 that constitutes the outermost layer portion 67. Next, a plurality of inner plates 54a are arranged so as to come into contact with the portions forming the outer surface of the outermost layer portion 67 among the plurality of spacers 66 forming the outermost layer portion 67 for each step between the four partition plates 58. By installing them, the three-stage inner molds 54 are each formed in a rectangular tube shape. Then, a plurality of outer vertical reinforcing bars 57a are formed in the through holes along the outer surface of the outermost layer portion 67 of the plurality of stages of the partition plates 58 which constitute the outermost layer portion 67 and are arranged at intervals in the vertical direction, and the plurality of inner side plates 54a. After being inserted by extending in the vertical direction so as to be positioned further outward, the outer horizontal reinforcing bar 27 extending in the horizontal direction is crossed with the outer vertical reinforcing bar 57a, and the intersection is fixed with a binding wire (not shown), The outer grid reinforcing bars 28 are formed. Next, after arranging a water-expandable water-stopping material (not shown) on the bottom plate 52 between the inner mold 54 and the outer mold 56, a grid-shaped reinforcing bar (not shown) is used. The outer peripheral surface of the storage complex 55 and the outer lattice reinforcing bars 28 (the plurality of outer longitudinal reinforcing bars 57a and the plurality of outer lateral reinforcing bars 27) are covered.

そして、底盤52上に外側型枠56の1段目及び2段目の基板18を組立てて、これらの基板18を中央部補強板19により結合し、水平方向に密着して並べられた複数の中央部補強板19の下縁及び両側縁に複数の端部補強板21を位置させかつこれらの端部補強板21により隣り合う基板18を結合し、互いに直角に突き当たる外側型枠56,56同士を外側角部連結板22で連結することにより、外側型枠56を外側縦鉄筋57aから所定の間隔をあけて四角枠状に形成する(図11)。このとき、補強用鉄筋を外側縦鉄筋57aと外側型枠56との間に位置させる。次に、外側セパレータ24の一端を外側横鉄筋27に係止し他端を1段目の基板18の係止孔18iに係止し、別の外側セパレータ24の一端を外側横鉄筋27に係止し他端を2段目の基板18の係止孔18iに係止する(図10)。   Then, the substrates 18 of the first and second stages of the outer mold 56 are assembled on the bottom plate 52, these substrates 18 are joined by the central reinforcing plate 19, and a plurality of them are arranged in close contact in the horizontal direction. Outer molds 56, 56 having a plurality of end reinforcing plates 21 positioned at the lower edge and both side edges of the central reinforcing plate 19, and adjoining the adjacent substrates 18 by these end reinforcing plates 21 and abutting each other at right angles. Are connected to each other by the outer corner connecting plates 22, so that the outer form frame 56 is formed in a square frame shape with a predetermined distance from the outer vertical rebar 57a (FIG. 11). At this time, the reinforcing rebar is positioned between the outer vertical rebar 57a and the outer form 56. Next, one end of the outer separator 24 is locked to the outer horizontal reinforcing bar 27, the other end is locked to the locking hole 18i of the first-stage substrate 18, and one end of another outer separator 24 is locked to the outer horizontal reinforcing bar 27. Then, the other end is locked in the locking hole 18i of the second stage substrate 18 (FIG. 10).

更に、2段目の基板18の上に、3段目の基板18を積み上げて、これらの基板18を中央部補強板19により結合し、水平方向に密着して並べられた複数の中央部補強板19の上縁及び両側縁に複数の端部補強板21を位置させかつこれらの端部補強板21により隣り合う基板18を結合し、互いに直角に突き当たる外側型枠56,56同士を外側角部連結板22で連結する。そして、外側セパレータ24の一端を外側横鉄筋27に係止し他端を3段目の基板18の係止孔18iに係止する。これにより自立性を有しかつ強固な外側型枠56を容易に組立てることができる。この結果、外側型枠としてラス網やレンガを用いた場合と比較して、外側型枠56の組立作業を大幅に短縮できる。   Further, the third-stage substrate 18 is stacked on the second-stage substrate 18, these substrates 18 are joined by the central-portion reinforcing plate 19, and a plurality of central-portion reinforcing members are arranged in close contact with each other in the horizontal direction. A plurality of end reinforcing plates 21 are positioned on the upper edge and both side edges of the plate 19, and the adjacent substrate 18 is joined by these end reinforcing plates 21, and the outer form frames 56, 56 that abut each other at right angles are connected to the outer corners. Part connection plates 22 are used for connection. Then, one end of the outer separator 24 is locked to the outer horizontal reinforcing bar 27 and the other end is locked to the locking hole 18i of the third-stage substrate 18. As a result, the self-supporting and strong outer mold 56 can be easily assembled. As a result, assembling work of the outer mold 56 can be significantly shortened as compared with the case where a lath net or brick is used as the outer mold.

その後、内側型枠54と外側型枠56の間に生コンクリートを流し込んで硬化させて側壁51を形成する(図10、図11及び図13)。このとき、最外層部67を構成する複数のスペーサ66とともに補助受け部材72が内側型枠54を受けるので、内側型枠54に作用する生コンクリートの圧力をスペーサ66及び補助受け部材72が受ける。この結果、内側型枠54と外側型枠56の間への生コンクリートの流込み時における貯留複合体55の変形を確実に防止できる。また、内側型枠54及び外側型枠56間に生コンクリートを一度に大量に流し込んでも、外側縦鉄筋57aが外側セパレータ24を介して外側型枠56を保持し、内側型枠54を最外層部67を構成する複数のスペーサ66とともに補助受け部材72が受けるので、外側型枠56及び内側型枠54が変形せずに、所定形状のコンクリート製の側壁51を形成できる。上記以外の動作及び効果は、第1の実施の形態の動作及び効果と略同様であるので、繰返しの説明を省略する。   After that, green concrete is poured between the inner mold 54 and the outer mold 56 to be hardened to form the side wall 51 (FIGS. 10, 11 and 13). At this time, since the auxiliary receiving member 72 receives the inner mold 54 together with the plurality of spacers 66 forming the outermost layer portion 67, the spacer 66 and the auxiliary receiving member 72 receive the pressure of the green concrete acting on the inner mold 54. As a result, it is possible to reliably prevent the deformation of the storage complex 55 during the pouring of the ready-mixed concrete between the inner mold 54 and the outer mold 56. Even if a large amount of green concrete is poured at a time between the inner mold 54 and the outer mold 56, the outer vertical rebars 57a hold the outer mold 56 through the outer separator 24, and the inner mold 54 is the outermost layer portion. Since the auxiliary receiving member 72 receives together with the plurality of spacers 66 that form 67, the outer side mold 56 and the inner side mold 54 are not deformed, and the concrete side wall 51 having a predetermined shape can be formed. The operations and effects other than those described above are substantially the same as the operations and effects of the first embodiment, and thus the repeated description will be omitted.
