Description

この発明は、土木建築工事おいてコンクリート型枠の堰板に使用される薄肉金属板製の型枠パネルに関する。   The present invention relates to a formwork panel made of a thin metal plate used for a dam plate of a concrete formwork in civil engineering construction work.

近年、木材合板製の型枠パネルに代って普及しつつある薄肉金属板製の型枠パネルは、一般に薄肉鋼板を屈曲させて片面側に開口する断面略コ字形のリブが複数並列に形成され、該リブにセパレータを挿通するためのセパ孔が等間隔で複数設けられている。この型枠パネルを用いて型枠を構築するには、前記リブの長手方向を上下にし、かつ非開口面側をコンクリート打設側に向けて型枠パネルを建て込み、対向する型枠パネルの互いに対応するセパ孔にセパレータを挿通し、そのセパレータの外周部に嵌合させた座金（鍔状体）を型枠パネルのコンクリート打設側の面に当接させるとともに、セパレータのセパ孔から突出させた先端部にフォームタイ（固定具）を型枠パネルの反対側の面に当接する状態に固着させ、これら座金とフォームタイとによって型枠パネルを挟み込む状態で固定する。そして、必要に応じて、建て込んだ型枠パネルの外側に鋼管を取り付けて補強する。   In recent years, formwork panels made of thin metal plates, which are becoming popular instead of wood plywood formwork panels, are generally formed by bending a thin steel plate and forming a plurality of ribs with a substantially U-shaped cross section that opens on one side. The rib is provided with a plurality of separator holes at equal intervals for inserting the separator. In order to construct a formwork using this formwork panel, the formwork panel is built with the longitudinal direction of the ribs up and down and the non-opening surface side facing the concrete placing side, and the opposite formwork panel The separators are inserted into the corresponding separator holes, and a washer (saddle-like body) fitted to the outer periphery of the separator is brought into contact with the surface of the formwork panel on the concrete placement side and protrudes from the separator hole of the separator. A foam tie (fixing tool) is fixed to the tip of the mold so as to abut on the opposite surface of the form panel, and the form panel is fixed between the washer and the form tie. And if necessary, a steel pipe is attached to the outside of the built-in formwork panel and reinforced.

上記薄肉鋼板製の型枠パネルの幅は６００〜９００ｍｍ程度であり、これを水平に並べて建て込んで所要長さの堰板を構築する。隣接する型枠パネル同士は、ビスによって連結される。このビスによる連結作業は現場で行なってもよいが、平らな別の場所で複数の型枠パネルを事前に連結してユニット化しておけば、現場での作業を簡略化することができる。このように複数の型枠パネルをユニット化する場合、現場に建て込んでからセパレータで固定するのは困難であるので、予め型枠パネルユニットにセパレータをフォームタイによって取り付けておき、その型枠パネルユニットを現場に建て込んだ後、その対向側にセパレータが取り付けられていない型枠パネルユニットを建て込み、前者のセパレータを後者に固定するという方法がとられる。   The width | variety of the said formwork panel made from a thin-walled steel plate is about 600-900 mm, this is arranged side by side and built, and the dam plate of required length is constructed | assembled. Adjacent formwork panels are connected by screws. The connecting operation using the screws may be performed on site, but if the plurality of formwork panels are connected in advance in another flat place and unitized, the on-site operation can be simplified. When a plurality of formwork panels are unitized in this way, it is difficult to fix them with a separator after being built in the field. Therefore, the separator is attached to the formwork panel unit with a foam tie in advance, and the formwork panel After the unit is built in the field, a method is adopted in which a formwork panel unit without a separator is installed on the opposite side, and the former separator is fixed to the latter.

上記型枠構築方法は、構造物の地上部分に適用することは可能であるが、建造物の基礎部分には適用できなかった。なぜならば、建造物の基礎部分の場合、地面よりも低く掘った溝の中に型枠パネルユニットを下ろして建て込まなければならないが、その際に、型枠パネルユニットに取り付けられているセパレータが型枠パネル建て込み位置の内側に組まれている鉄筋と干渉するからである。   The above-mentioned form construction method can be applied to the ground part of the structure, but cannot be applied to the foundation part of the building. This is because, in the case of the foundation part of a building, the formwork panel unit must be installed in a groove dug lower than the ground. At that time, the separator attached to the formwork panel unit It is because it interferes with the reinforcing bar built inside the formwork panel installation position.

そこで、セパ孔をセパレータの座金が挿通可能な形状とすることにより、型枠パネルを建て込んでからでもセパレータによる固定を可能にした型枠パネルが提案されている（特許文献１）。
特開平１０−８８７１５号公報 In view of this, there has been proposed a formwork panel in which the separator hole has a shape that allows the washer of the separator to be inserted, so that the separator panel can be fixed even after the formwork panel is built (Patent Document 1).
JP-A-10-88715

特許文献１に記載の型枠パネルは、木材合板製型枠パネルで用いていたセパレータ及びフォームタイをそのまま使用する場合、木材合板製型枠パネルの板厚（１２ｍｍ）に合わせてセパレータに対するフォームタイの固着位置を調節するために、型枠パネルとフォームタイの間にスペーサを介在させる必要があった。このため、型枠の組立て作業が面倒であるという問題点があり、スペーサを必要としない型枠パネルの開発が待たれていた。   In the case of using the separator and the foam tie used in the wood plywood formwork panel as they are, the form panel described in Patent Document 1 is a foam tie for the separator in accordance with the thickness (12 mm) of the wood plywood formwork panel. In order to adjust the fixing position, a spacer has to be interposed between the formwork panel and the foam tie. For this reason, there is a problem that the assembling work of the mold is troublesome, and development of a mold panel that does not require a spacer has been awaited.

本発明は、上記事情に鑑みなされたものであり、スペーサを必要とせずに、現場に建て込んでからセパレータをセパ孔に挿通して固定することのできる薄肉金属板製の型枠パネルを提供することを課題としている。   The present invention has been made in view of the above circumstances, and provides a form panel made of a thin metal plate that does not require a spacer and can be installed on the site and then inserted into a separator hole to be fixed. The challenge is to do.

上記課題を解決するために、本発明は次のように構成した。すなわち、請求項１に記載の型枠パネルは、薄肉金属板を屈曲させて片面側に開口する断面略コ字形のリブを複数並列に形成し、該リブにセパレータを挿通するためのセパ孔を設けてなり、前記リブの長手方向を上下にし、かつリブ非開口面側をコンクリート打設側に向けて建て込み、前記セパ孔に挿通したセパレータの外周部に形成されている鍔状体をリブ非開口面に当接させるとともに、該セパレータの先端部に固着させた固定具をリブ開口面に当接させ、これら鍔状体と固定具とによって挟み込む状態で固定される型枠パネルにおいて、前記リブの開口部の幅を、前記固定具のリブ当接面の外径よりも狭く形成するとともに、前記セパ孔は、リブ長手方向の長さの方が同幅方向の長さよりも大きく鍔状体が挿通可能な形状とし、そのリブ幅方向の長さを鍔状体の最大径部の長さよりも小さくしたことを特徴としている。   In order to solve the above problems, the present invention is configured as follows. That is, the formwork panel according to claim 1 is formed by forming a plurality of substantially U-shaped ribs opened in one side by bending a thin metal plate in parallel, and separating holes for inserting the separators into the ribs. The rib-like body formed on the outer peripheral portion of the separator that is provided and is built with the longitudinal direction of the rib up and down and the rib non-opening surface side facing the concrete placing side, is inserted into the separator hole. In the formwork panel which is brought into contact with the non-opening surface and fixed with the fixing member fixed to the tip end portion of the separator being brought into contact with the rib opening surface and sandwiched between the hook-shaped body and the fixing device, The width of the opening of the rib is formed to be narrower than the outer diameter of the rib contact surface of the fixture, and the length of the separation hole in the rib longitudinal direction is larger than the length in the same width direction. Make the body into a shape that can be inserted. It is characterized in that the length in the width direction is smaller than the length of the maximum diameter portion of the flange-like body.

セパ孔を鍔状体が挿通可能な形状とすることにより、対向して建て込まれた１組の型枠パネルの互いに対応するそれぞれのセパ孔に、外周部に鍔状体が形成されているセパレータを型枠パネルのリブ開口側から挿通させることができる。セパレータは水平に挿通されるので、型枠パネル建て込み位置の内側に組まれている鉄筋とセパレータが干渉しない。セパ孔に挿通されたセパレータを中心軸回りに回動させて、鍔状体の最大径部をリブ幅方向に向けることにより、該鍔状体がセパ孔のリブ幅方向両側部に干渉してセパ孔からリブ開口側に抜けなくなる。また、セパ孔からリブ開口側に突出したセパレータの端部に固定具を固着させると、リブ開口部の幅は固定具のリブ当接面の外径よりも狭いので、固定具がリブ開口部のリブ幅方向両側部に干渉してセパレータのリブ非開口側への移動が規制される。したがって、スペーサを使用せずに、型枠パネルのリブ非開口面に当接する鍔状体と型枠パネルのリブ開口面に当接する固定具とによって型枠パネルを挟み込む状態に固定することができる。このセパレータによる型枠パネルの連結作業は、多数の型枠パネルを建て込んでから行える。   By making the sepa hole into a shape through which the saddle-like body can be inserted, the saddle-like body is formed on the outer peripheral portion of each of the sepa-holes corresponding to each other in a pair of formwork panels built facing each other. The separator can be inserted from the rib opening side of the formwork panel. Since the separator is inserted horizontally, the reinforcing bar built inside the formwork panel built-in position does not interfere with the separator. By rotating the separator inserted through the separator hole around the central axis and directing the maximum diameter portion of the bowl in the rib width direction, the bowl interferes with both sides of the separator hole in the rib width direction. It will not come out from the separation hole to the rib opening side. Further, when the fixture is fixed to the end of the separator protruding from the separator hole to the rib opening side, the width of the rib opening is narrower than the outer diameter of the rib contact surface of the fixture. The movement of the separator toward the non-opening side of the rib is restricted by interfering with both sides of the rib width direction. Therefore, without using a spacer, the mold panel can be fixed in a state of being sandwiched by the hook-shaped body that abuts against the rib non-opening surface of the mold panel and the fixture that abuts the rib opening surface of the mold panel. . The work of connecting the formwork panels with the separator can be performed after a large number of formwork panels are installed.

また、請求項２に記載の型枠パネルは、請求項１に記載の構成に加えて、前記セパ孔は、輪郭の一部に形成された接続部を介して輪郭内と輪郭外とが接続し、初期状態では輪郭内部位によって孔が閉塞しており、輪郭内部位をリブ非開口側に押し込むことにより開口する形態とされるとともに、輪郭内部位をリブ開口側に引き戻す工具を係合させるための小孔が輪郭内部位に形成されている構成としている。   Moreover, in addition to the structure of Claim 1, the formwork panel of Claim 2 connects the inside of an outline and the outline outside via the connection part formed in a part of outline. In the initial state, the hole is closed by the site in the contour, and the shape is opened by pushing the site in the contour toward the non-rib opening side, and the tool for pulling the site in the contour back to the rib opening side is engaged. Therefore, a small hole is formed in the contour portion.

型枠パネルには多数のセパ孔が設けられるが、全てのセパ孔にセパレータが挿通されるわけではない。このため、セパ孔が初期状態から開口していると、セパレータが挿通されないセパ孔から打設した生コンクリートが型枠外に漏出してしまう。また、セパ孔の面積はセパの軸部の断面積よりもかなり広いため、セパ孔にセパレータの軸部が挿通されたままであると、セパ孔の隙間から打設した生コンクリートが型枠外に漏出するおそれがある。請求項２に記載の構成とすると、セパレータが挿通されないセパ孔から生コンクリートが型枠外に漏出することを防止できる。また、セパ孔にセパレータを挿通させた後、小孔に工具を係合させ輪郭内部位をリブ開口側に引き戻してセパ孔の隙間を塞ぐことにより、該隙間から生コンクリートが型枠外に漏出することを防止できる。   A large number of separator holes are provided in the formwork panel, but the separators are not inserted into all the separator holes. For this reason, when the separator hole is opened from the initial state, the ready-mixed concrete cast from the separator hole through which the separator is not inserted leaks out of the mold. In addition, since the area of the separator hole is considerably larger than the cross-sectional area of the shaft part of the separator, if the separator shaft part is still inserted into the separator hole, the ready-mixed concrete cast from the gap of the separator hole leaks out of the mold There is a risk. If it is set as the structure of Claim 2, it can prevent that ready-mixed concrete leaks out of a formwork from the separator hole into which a separator is not penetrated. In addition, after the separator is inserted into the separator hole, the tool is engaged with the small hole, the inner portion of the contour is pulled back to the rib opening side to close the gap of the separator hole, and the ready-mixed concrete leaks out of the mold from the gap. Can be prevented.

さらに、請求項３に記載されているように、セパレータによってセパ孔の輪郭内部位をリブ非開口側に押し込んだ後、該輪郭内部位をリブ開口側に引き戻した場合に、セパレータに係合して輪郭内部位の位置ずれを規制する係合部が輪郭内部位に形成されている構成とすると、打設される生コンクリートの圧力を受けても輪郭内部位が動きにくくなるので、セパレータが挿通されたセパ孔を塞いだ状態のまま保つことができる。   Furthermore, as described in claim 3, when the inner portion of the separator hole is pushed toward the rib non-opening side by the separator and then the inner portion of the contour is pulled back to the rib opening side, the separator is engaged. If the engagement part that regulates the position shift of the part in the contour is formed in the part in the contour, the part in the contour becomes difficult to move even under the pressure of the ready-mixed concrete, so the separator is inserted. The separated hole can be kept closed.

請求項１〜３によれば、型枠パネル建て込み位置の内側に組まれている鉄筋と干渉することなく、対向して建て込まれた１組の型枠パネルの互いに対応するそれぞれのセパ孔にセパレータを挿通させることができるので、事前に複数枚の型枠パネルを連結一体化した型枠パネルユニットの使用が可能になるとともに、セパ孔に挿通されたセパレータと型枠パネルとの固定にスペーサを必要としないので、この固定作業が簡略化されるようになり、型枠構築作業全般を効率的に行えるという効果を奏する。   According to the first to third aspects, each of the corresponding pair of separating holes of the pair of formwork panels built facing each other without interfering with the reinforcing bars built inside the formwork panel built-in position. It is possible to use a formwork panel unit in which a plurality of formwork panels are connected and integrated in advance, and to fix the separator inserted into the separator hole and the formwork panel. Since a spacer is not required, this fixing work is simplified, and the entire formwork construction work can be efficiently performed.

請求項２、３によれば、セパレータを挿通するとき以外はセパ孔が輪郭内部位で塞がれているので、セパレータが挿通されないセパ孔から生コンクリートが型枠外に漏出すること、及びセパレータが挿通されたセパ孔の隙間から生コンクリートが型枠外に漏出することを防止できるという効果を奏する。   According to Claims 2 and 3, since the separator hole is closed at the site in the contour except when the separator is inserted, the ready-mixed concrete leaks out of the mold from the separator hole through which the separator is not inserted, and the separator There is an effect that it is possible to prevent the ready-mixed concrete from leaking out of the formwork through the gap between the inserted separator holes.

請求項３によれば、打設される生コンクリートの圧力を受けてもセパ孔を塞ぐ輪郭内部位が動きにくくなるので、セパ孔を塞いだ状態のまま保つことができ、セパ孔からの生コンクリートの漏出を確実に防止できるという効果を奏する。   According to the third aspect, since the portion in the contour that closes the separation hole becomes difficult to move even under the pressure of the ready-mixed concrete to be placed, the separation hole can be kept closed, and the raw material from the separation hole can be maintained. There is an effect that concrete leakage can be surely prevented.

本発明を実施するための最良の形態を、以下に示す実施例に基づき具体的に説明する。   The best mode for carrying out the present invention will be specifically described based on the following examples.

図１及び図２は本発明の１実施例を表している。この型枠パネル１は、表面が亜鉛等でメッキされた薄肉鋼鈑をプレス加工により成形したものであって、断面略コ字形をしたリブ２，…が等間隔で複数並列に形成され、さらにリブ２とリブ２の間には同方向の半円形小リブ３，３が２本ずつ形成されている。２本の小リブ３，３の間隔部には、折り曲げを容易にするための短い切れ目４，…が同一線上に等間隔で多数形成されている。リブ２の開口部の幅Ｗは、後記固定具１４（図７参照）のリブ当接面の外径Ｄよりも狭く設定されている。   1 and 2 show an embodiment of the present invention. This formwork panel 1 is formed by pressing a thin steel plate whose surface is plated with zinc or the like, and a plurality of ribs 2 having a substantially U-shaped cross section are formed in parallel at equal intervals. Two semicircular small ribs 3 and 3 are formed between the ribs 2 and 2 in the same direction. A plurality of short cuts 4,... For facilitating bending are formed on the same line at equal intervals in the space between the two small ribs 3 and 3. The width W of the opening of the rib 2 is set to be narrower than the outer diameter D of the rib contact surface of the fixture 14 (see FIG. 7) described later.

リブ２には、セパレータを挿通するためのセパ孔５が等間隔で複数形成されている。このセパ孔５は、図２に詳細に示すように、リブ長手方向に長い六角形の主部５ａと該主部よりも幅が狭く端部Ａが円弧状をした副部５ｂとを組み合わせた輪郭形状で、全体的にはリブ長手方向に長くなっている。副部５ｂの反対側に位置する主部５ａの端部Ｂを残して、輪郭線に沿って切り込みが入れられている。換言すると、このセパ孔５は、輪郭の一部に形成された接続部（端部Ｂ）を介して輪郭内と輪郭外とが接続した形態であり、初期状態では輪郭内部位７によって孔が塞がれており、セパレータを挿通して輪郭内部位７をリブ非開口側に押し込むことにより開口するようになっている。また、輪郭内部位７には、シノ等の先端が細い工具を挿入して係合させることのできる円形の小孔８が形成されている。セパ孔５は後記セパレータ１２の鍔状部１２ａが挿通可能である。   In the rib 2, a plurality of separator holes 5 for inserting the separator are formed at equal intervals. As shown in detail in FIG. 2, the separator hole 5 is a combination of a hexagonal main portion 5 a that is long in the rib longitudinal direction and a sub-portion 5 b that is narrower than the main portion and has an arcuate end A. It has a contour shape and is generally long in the rib longitudinal direction. A cut is made along the contour, leaving the end B of the main part 5a located on the opposite side of the sub part 5b. In other words, this separate hole 5 is a form in which the inside and outside of the contour are connected via a connecting portion (end portion B) formed in a part of the contour. It is closed, and is opened by inserting the separator and pushing the in-contour portion 7 toward the non-rib opening side. In addition, a circular small hole 8 into which a tool having a thin tip such as a chin can be inserted and engaged is formed in the in-contour portion 7. The separator hole 5 can be inserted with a flange-shaped portion 12a of a separator 12 which will be described later.

型枠パネル１の幅すなわちリブ長手方向と直交する方向の長さは、両端から中央部にまで手が届く程度、例えば６８０ｍｍとしている。両端のリブ２にはセパ孔５が設けられておらず、そのうち一方のリブには隣接するパネル同士を連結するビスを挿通するためのビス孔９が同間隔で設けられている。   The width of the formwork panel 1, that is, the length in the direction perpendicular to the longitudinal direction of the ribs is set such that it can be reached from both ends to the center, for example, 680 mm. Sepa holes 5 are not provided in the ribs 2 at both ends, and screw holes 9 for inserting screws for connecting adjacent panels are provided at the same interval on one of the ribs.

次に、この型枠パネル１を用いた型枠構築方法を、図３に示す型枠に基づいて説明する。
まず、幅方向に並べた複数枚の型枠パネル１をビスによって連結して、型枠パネルユニットＵを作製する。図示例の場合、４枚の型枠パネル１で１組の型枠パネルユニットとしている。この作業は、型枠構築現場とは別の平らな場所で行うとよい。型枠パネルユニットＵを型枠構築現場まで運搬し、それを捨てコンクリート１０の上に固定されたライナー金具１１に下端部を嵌合させて建て込む。そして、対向する型枠パネル１，１同士をセパレータ１２等によって互いに連結する。このように、事前に複数枚の型枠パネル１を連結した型枠パネルユニットＵを作製しておくと、現場での型枠構築作業を効率的に行うことができる。型枠パネルユニットによる型枠構築を可能にしているのは、本発明にかかる型枠パネル１のセパ孔５及び後述するセパレータ１２の鍔状体１２ｂの互いに関連し合う特有の形態に因る。Next, a method for constructing a form using the form panel 1 will be described based on the form shown in FIG.
First, a plurality of formwork panels 1 arranged in the width direction are connected by screws to produce a formwork panel unit U. In the case of the illustrated example, the four formwork panels 1 constitute a set of formwork panel units. This work may be performed on a flat place different from the formwork construction site. The formwork panel unit U is transported to the formwork construction site, and it is discarded, and the lower end part is fitted into the liner metal fitting 11 fixed on the concrete 10 and built. And the opposing formwork panels 1 and 1 are mutually connected by the separator 12 grade | etc.,. Thus, if the formwork panel unit U which connected the several formwork panel 1 in advance is produced, the formwork construction work in the field can be performed efficiently. The reason why the formwork construction by the formwork panel unit is possible is due to the unique form of the separator hole 5 of the formwork panel 1 according to the present invention and the saddle-like body 12b of the separator 12 which will be described later.

セパレータ１２は、図４に示すように、丸棒状の軸部の両端に雄ねじ部１２ａが形成され、さらにそれより少し中心寄りに一方向に長い六角形をした鍔状体１２ｂが一体に形成されている。鍔状体１２ｂはセパ孔５の主部５ａより若干小さく形成されているので、鍔状体１２ｂとセパ孔５の向きを揃えることにより、セパレータ１２をセパ孔５に挿通することができる。また、前記セパ孔５のリブ幅方向の長さＬ１は鍔状体１２ｂの最大径部の長さＬ２よりも小さく設定されているので、鍔状体１２ｂの最大径部がセパ孔５のリブ幅方向を向くようにするとセパレータ１２がセパ孔５を通らなくなる。   As shown in FIG. 4, the separator 12 has male threaded portions 12a formed at both ends of a round rod-shaped shaft portion, and a hexagonal hook-shaped body 12b that is long in one direction slightly closer to the center. ing. Since the bowl-shaped body 12 b is formed slightly smaller than the main portion 5 a of the separator hole 5, the separator 12 can be inserted into the separator hole 5 by aligning the orientation of the bowl-shaped body 12 b and the separator hole 5. Further, since the length L1 of the separation hole 5 in the rib width direction is set to be smaller than the length L2 of the maximum diameter portion of the flange 12b, the maximum diameter of the flange 12b is the rib of the separation hole 5. If it is made to face in the width direction, the separator 12 will not pass through the separator hole 5.

図５はセパレータ１２と型枠パネル１，１の連結部の断面図である。型枠パネル１，１の互いに対応する一対のセパ孔５，５に対し、一方側（図５における右側）からセパレータ１２を挿通する。両パネル間には鉄筋１３が組まれているが、セパレータ１２は軸方向に水平に挿通されるので鉄筋１３と干渉しない。挿入方向上手側型枠パネル１のセパ孔５は、セパレータ１２の鍔状部１２ｂによって輪郭内部位７が押し込まれて開口する。一方、挿入方向下手側型枠パネル１のセパ孔５は閉塞したままで、その小孔８にセパレータ１２の先端部が挿通される。これにより、一対のセパ孔５，５からセパレータ１２の両端部が外側に突出した状態となる。その状態でセパレータ１２を軸回りに９０度回転させて鍔状体１２ｂ，１２ｂの最大径部をセパ孔５のリブ幅方向に向けることにより、鍔状体１２ｂ，１２ｂを型枠パネル１のリブ非開口面に当接させる。そして、セパレータ１２の雄ねじ部１２ａ，１２ａに固定具１４，１４を螺着し、該固定具の端面を型枠パネル１のリブ開口面に当接させて、鍔状体１２ｂと固定具１４とにより型枠パネル１を両側から挟み付けて固定する。   FIG. 5 is a cross-sectional view of the connecting portion between the separator 12 and the formwork panels 1 and 1. The separator 12 is inserted from one side (the right side in FIG. 5) into the pair of separator holes 5 and 5 corresponding to each other of the formwork panels 1 and 1. Reinforcing bars 13 are assembled between both panels, but the separator 12 does not interfere with the reinforcing bars 13 because it is inserted horizontally in the axial direction. The separation hole 5 of the upper-side mold panel 1 in the insertion direction is opened by the in-contour portion 7 being pushed in by the flange-shaped portion 12 b of the separator 12. On the other hand, the front end portion of the separator 12 is inserted into the small hole 8 while the separation hole 5 of the lower side mold panel 1 in the insertion direction remains closed. As a result, both end portions of the separator 12 protrude from the pair of separator holes 5 and 5 to the outside. In this state, the separator 12 is rotated 90 degrees around the axis so that the maximum diameter portions of the flanges 12b and 12b are directed in the rib width direction of the separator hole 5, so that the flanges 12b and 12b are ribs of the mold panel 1. Abut on the non-opening surface. Then, the fasteners 14, 14 are screwed onto the male screw portions 12 a, 12 a of the separator 12, and the end surfaces of the fixtures are brought into contact with the rib opening surfaces of the formwork panel 1, so that the hook-shaped body 12 b, the fixture 14, Then, the mold panel 1 is clamped from both sides and fixed.

上記のままであると、セパレータ挿通方向上手側の型枠パネル１のセパ孔５は開口した状態であるので、コンクリート打設時にそこから生コンクリートが漏出するおそれがある。そこで、図５において二点鎖線で示すように、シノのような先端部が細くなった工具１５を小孔８に係合させて当該輪郭内部位７を外側に引き戻し、セパ孔５を塞ぐようにする。図６及び図７はセパ孔が塞がれた状態を表している。円弧状をした輪郭内部位７の係合部（端部Ａ）がセパレータ１２に係合するため、生コンクリートの圧力がかかっても輪郭内部位７が位置ずれしない。セパレータ１２を挿通しないセパ孔５は閉塞状態のままにしておく。   If the above is maintained, the separator hole 5 of the mold panel 1 on the upper side in the separator insertion direction is in an open state. Therefore, as shown by a two-dot chain line in FIG. 5, a tool 15 having a thin tip such as Shino is engaged with the small hole 8 so that the contoured portion 7 is pulled back to close the separation hole 5. To. 6 and 7 show a state where the separator hole is closed. Since the engaging portion (end A) of the arcuate contour portion 7 is engaged with the separator 12, the contour portion 7 is not displaced even when the pressure of ready-mixed concrete is applied. The separator hole 5 through which the separator 12 is not inserted is left closed.

セパレータ１２による型枠パネル１，１の連結が完了したならば、両側の型枠パネル１，１の外面側に上下一対の鋼管１６，１６を水平方向に配し、それをセパレータ１２の端部に固定する。最後に、建て込んだ型枠パネル１の上端部にライナー金具１１を逆向きに被せて取り付ける。このように組み立てられた型枠に生コンクリートを打設すると、セパ孔５からコンクリートが漏出することなく、セパレータ１２が挿通されていない小孔８から余剰水を排出させながら、型枠の隅々まで生コンクリートが充填される。   When the connection of the formwork panels 1 and 1 by the separator 12 is completed, a pair of upper and lower steel pipes 16 and 16 are disposed in the horizontal direction on the outer surface side of the formwork panels 1 and 1 on both sides, and the end of the separator 12 Secure to. Finally, the liner metal fitting 11 is attached to the upper end portion of the built-in formwork panel 1 in the reverse direction. When ready-mixed concrete is placed on the mold thus assembled, the concrete is not leaked from the separator holes 5 and the excess water is discharged from the small holes 8 through which the separators 12 are not inserted. Ready-mixed concrete.

図８はセパ孔の形状が異なる型枠パネルの要部を表している。この実施例２のセパ孔２０は、実施例１のセパ孔５の角部を曲線状にすることにより、該角部に応力が集中することを避けて、型枠パネル自体の強度向上が図られている。このセパ孔２０を備えた型枠パネルには、図４に示すセパレータ１２の鍔状部１２ｂの角部が曲線状に形成されたセパレータ（図示省略）が使用される。   FIG. 8 shows a main part of a formwork panel having a different shape of the separator hole. The separator hole 20 of the second embodiment has a curved corner portion of the separator hole 5 of the first embodiment, thereby avoiding concentration of stress on the corner portion and improving the strength of the formwork panel itself. It has been. For the formwork panel provided with the separator hole 20, a separator (not shown) in which the corners of the hook-shaped portion 12b of the separator 12 shown in FIG. 4 are curved is used.

図９はさらにセパ孔の形状が異なる型枠パネルの要部を表している。この実施例３のセパ孔２１は、円形の主部２１ａと該主部のリブ長手方向両側に続く幅の狭い副部２１ｂ，２１ｂとからなる輪郭形状で、実施例１、２のセパ孔と同様に全体的にはリブ長手方向に長くなっている。また、輪郭の一部に形成された接続部Ｃを介して輪郭内と輪郭外とが接続した形態であり、初期状態では輪郭内部位２２によって孔が塞がれており、セパレータを挿通して輪郭内部位２２をリブ非開口面側に押し込むことにより開口するようになっている。   FIG. 9 further shows the main part of a formwork panel having a different shape of the separator hole. The separator hole 21 of the third embodiment has a contour shape including a circular main portion 21a and narrow sub-portions 21b and 21b continuing on both sides of the main portion in the longitudinal direction of the rib. Similarly, it is generally long in the rib longitudinal direction. In addition, the inside and outside of the contour are connected via a connecting portion C formed in a part of the contour. In the initial state, the hole is closed by the contour portion 22 and the separator is inserted. Opening is performed by pushing the in-contour portion 22 toward the non-opening surface side of the rib.

上記セパ孔２１を備えた型枠パネルには、図１０に示すセパレータ２５が使用される。２５ａは雄ねじ部、２５ｂは鍔状部である。鍔状体２５ｂは、セパ孔２１に対応する形状で、セパ孔２１より若干小さく形成されている。したがって、鍔状体２５ｂとセパ孔２１の向きを揃えることにより、セパレータ１２をセパ孔２１に挿通することができる。また、前記セパ孔２１のリブ幅方向の長さＬ３は鍔状体２５ｂの最大径部の長さＬ４よりも小さく設定されているので、鍔状体２５ｂの最大径部がセパ孔２１のリブ幅方向を向くようにするとセパレータ２５がセパ孔２１を通らなくなる。   A separator 25 shown in FIG. 10 is used for the formwork panel provided with the separator hole 21. 25a is an external thread part, 25b is a bowl-shaped part. The bowl-shaped body 25 b has a shape corresponding to the separator hole 21 and is slightly smaller than the separator hole 21. Therefore, the separator 12 can be inserted into the separator hole 21 by aligning the orientation of the flange 25b and the separator hole 21. Further, since the length L3 in the rib width direction of the separation hole 21 is set to be smaller than the length L4 of the maximum diameter portion of the flange 25b, the maximum diameter of the flange 25b is the rib of the separation hole 21. The separator 25 does not pass through the separator hole 21 when facing the width direction.

実施例２の型枠パネル２０も、実施例１の型枠パネル１と同様に、セパ孔２１に挿通されたセパレータ２５の鍔状体２５ｂと該セパレータの先端部に螺着した固定具１４とにより両側から挟まれた状態で固定される。鍔状体２５ｂの長手方向をリブ幅方向に向けて鍔状体２５ｂを型枠パネル２０のリブ非開口面に当接させると、セパ孔２１の主部２１ａは塞がれ、副部２１ｂ，２１ｂだけが開口した状態となる。副部２１ｂは面積が狭いので、ここから生コンクリートが漏出することはない。開口した副部２１ｂ，２１ｂは余剰水の排出口として利用される。   Similarly to the mold panel 1 of the first embodiment, the mold panel 20 of the second embodiment also has a hook-like body 25b of the separator 25 inserted into the separator hole 21 and a fixture 14 screwed to the tip of the separator. Is fixed in a state of being sandwiched from both sides. When the flange 25b is brought into contact with the rib non-opening surface of the mold panel 20 with the longitudinal direction of the flange 25b facing the rib width direction, the main portion 21a of the separator hole 21 is closed, and the sub-portions 21b, Only 21b is opened. Since the sub-part 21b has a small area, the ready-mixed concrete does not leak from here. The opened sub-parts 21b and 21b are used as discharge ports for excess water.

本発明は上記実施例１、２、３に限定されるものではなく、セパレータの鍔状体がセパ孔を挿通可能で、かつ鍔状体が型枠パネルのリブ非開口面に当接させられるという条件を満たすならば、セパ孔及びセパレータの鍔状部を別な形状とすることができる。例えば、セパレータを図１１や図１２のようにしてもよい。図１１に示すセパレータは、鍔状体を楕円形としている。図１２に示すセパレータは、軸の一部をカシメにより耳状に突出させ、これを鍔状部の代わりとしている。また、実施例１、２、３のセパ孔５，２０，２１は、いずれも輪郭内と輪郭外とを接続する接続部が１箇所だけであるが、該接続部が複数箇所にある構成としてもよい。   The present invention is not limited to the first, second, and third embodiments. The separator-like body can be inserted into the separator hole, and the collar-like body is brought into contact with the rib non-opening surface of the formwork panel. If the above condition is satisfied, the separator hole and the flanged portion of the separator can have different shapes. For example, the separator may be as shown in FIGS. The separator shown in FIG. 11 has a bowl-like body that is elliptical. In the separator shown in FIG. 12, a part of the shaft is protruded in an ear shape by caulking, and this is used instead of the hook-shaped portion. In addition, in each of the first, second, and third embodiments, the separator holes 5, 20, and 21 have only one connection portion that connects the inside and outside of the contour, but the connection portion has a plurality of locations. Also good.
