Description

本発明は、コンクリート板の製造方法およびそれに用いる型枠構造に関する。
さらに詳しくは、側面に溝等が形成されるプレキャストコンクリート板などのコンクリート板の製造を容易になし得るコンクリート板の製造方法およびそれに用いる型枠構造に関する。 The present invention relates to a method for producing a concrete plate and a formwork structure used therefor.
More specifically, the present invention relates to a method for producing a concrete plate that can easily produce a concrete plate such as a precast concrete plate in which a groove or the like is formed on a side surface, and a formwork structure used therefor.

従来、ＰＣ板（プレキャストコンクリート板）などのコンクリート板の製造は、図６に示すように、定盤１０１の上に側枠１０２を設けることによって型枠１００を形成し、形成された型枠１００内部にコンクリートを打設してなされるのが通常である。このとき、コンクリート材１０３の側面に気密材用の溝を設けたり、等圧空間確保用の溝を設けたりする場合には、側枠１０２に溝型１０４を設け、これにより成形を行うものとされる。   Conventionally, a concrete plate such as a PC plate (precast concrete plate) is manufactured by forming a mold 100 by providing a side frame 102 on a surface plate 101, as shown in FIG. It is usually done by placing concrete inside. At this time, when a groove for an airtight material is provided on the side surface of the concrete material 103 or a groove for securing an isobaric space is provided, a groove mold 104 is provided on the side frame 102, thereby performing molding. Is done.

コンクリート材１０３の成形後は、図７に示すように、側枠１０２を取り外し、コンクリート材を吊り上げるなどして脱型される。このため、多数のコンクリート板を製造する必要がある場合には、１枚の成型が終わる度にコンクリート材１０３の寸法に合わせて側枠１０２の設置作業を行わねばならず、一定サイズのコンクリート板１０３を製造する際においても工程数が無用に増大するといった問題がある。   After the concrete material 103 is formed, as shown in FIG. 7, the side frame 102 is removed and the concrete material is lifted to remove the mold. For this reason, when it is necessary to manufacture a large number of concrete plates, the installation work of the side frame 102 must be performed in accordance with the dimensions of the concrete material 103 every time one piece of molding is finished. There is also a problem that the number of steps increases unnecessarily when manufacturing 103.

また、図８に示すように、模様板などを製造するための型枠２００においては、定盤ではなく面型２０１と側枠２０２とが一体化された型枠を用いるのが通常であり、この場合、側枠２０２に溝型などを設けるとコンクリート材の脱型ができなくなるといった別の問題も生じる。   Further, as shown in FIG. 8, in the mold frame 200 for manufacturing a pattern board or the like, it is normal to use a mold frame in which the surface mold 201 and the side frame 202 are integrated instead of the surface plate. In this case, when a groove mold or the like is provided in the side frame 202, another problem that the demolding of the concrete material cannot be performed occurs.

本発明はかかる従来技術の課題に鑑みなされたものであって、コンクリート板の製造における工程数を削減するとともに、側枠が面型と一体である型枠においてもコンクリート材側面を容易に所望形状に形成することが可能なコンクリート板の製造方法およびそれに用いる型枠構造を提供することを目的としている。   The present invention has been made in view of the problems of the prior art, and reduces the number of steps in the production of concrete plates, and easily forms the side surface of the concrete material even in the formwork in which the side frame is integrated with the face mold. It is an object of the present invention to provide a method for producing a concrete plate that can be formed into a sheet and a formwork structure used therefor.

本発明のコンクリート板の製造方法は、型枠を用いるコンクリート板の製造方法であって、前記型枠が、外枠と該外枠に着脱自在に装着される型材とからなり、打設コンクリート養生後にコンクリートを前記型材とともに脱型し、ついで同型材を取り外すことを特徴とする。   The method for producing a concrete plate according to the present invention is a method for producing a concrete plate using a mold, wherein the mold is composed of an outer frame and a mold that is detachably attached to the outer frame, and the concrete is cured. The concrete is subsequently demolded together with the mold material, and then the same mold material is removed.

本発明の型枠構造は、コンクリート板の製造方法に用いられる型枠構造であって、前記型枠構造が、外枠と該外枠に着脱自在に装着される型材とからなることを特徴とする。   The formwork structure of the present invention is a formwork structure used in a method for producing a concrete plate, wherein the formwork structure comprises an outer frame and a mold material that is detachably attached to the outer frame. To do.

本発明の型枠構造においては、前記型材が、コンクリート板の側面を所望形状に成形する側面型と、外枠と係合する係合部を有してなるのが好ましい。   In the mold structure of the present invention, it is preferable that the mold material has a side mold that molds the side surface of the concrete plate into a desired shape and an engaging portion that engages with the outer frame.

本発明によれば、側面の溝などを有するコンクリート板の生産性が向上するという優れた効果が得られる。   According to the present invention, it is possible to obtain an excellent effect that the productivity of a concrete plate having side grooves and the like is improved.

以下、添付図面を参照しながら本発明を実施形態に基づいて説明するが、本発明はかかる実施形態のみに限定されるものではない。   Hereinafter, although the present invention is explained based on an embodiment, referring to an accompanying drawing, the present invention is not limited only to this embodiment.

図１に、本発明の一実施形態に係るコンクリート板の製造方法に適用される型枠構造（以下、単に型枠という）Ｋを示す。   FIG. 1 shows a formwork structure (hereinafter simply referred to as a formwork) K applied to a method for producing a concrete plate according to an embodiment of the present invention.

型枠Ｋは、例えばＰＣ板（プレキャストコンクリート板）とされたコンクリート板Ｗ（図３、図４参照）を製造するための型枠であり、定盤１の上に、コンクリート板Ｗの形状、寸法に合わせて側枠２を設けてなるものとされる。   The formwork K is a formwork for manufacturing the concrete board W (refer FIG. 3, FIG. 4) made into PC board (precast concrete board), for example, on the surface plate 1, the shape of the concrete board W, The side frame 2 is provided in accordance with the dimensions.

側枠２は、図２に示すように、定盤１に取り付けられる外枠１１と、外枠１１に装着される型材１２とから構成される。   As shown in FIG. 2, the side frame 2 includes an outer frame 11 attached to the surface plate 1 and a mold member 12 attached to the outer frame 11.

外枠１１は、例えば溝形鋼からなり、開口部を型の外側に向けた状態で定盤１に取り付けられる。   The outer frame 11 is made of, for example, channel steel, and is attached to the surface plate 1 with the opening facing the outside of the mold.

型材１２は、コンクリート板Ｗの側面を所望形状（例えば、溝形）に成形するための側面型１２ａを有するとともに、コンクリート板Ｗの成型後に型材１２をコンクリート板Ｗとともに外枠１１から離脱できるような態様で外枠１１と係合する（図３参照）係合部１２ｂを有してなるものとされる。   The mold material 12 includes a side mold 12a for molding the side surface of the concrete plate W into a desired shape (for example, a groove shape), and the mold material 12 can be detached from the outer frame 11 together with the concrete plate W after the concrete plate W is molded. In this manner, the engaging portion 12b is engaged with the outer frame 11 (see FIG. 3).

係合部１２ｂは、図３に示すように、外枠１１の上面と当接する板状の上面当接部１２ｃと、これと垂直に形成され、外枠１１の型内側面と当接する板状の内側面当接部１２ｄとから構成されており、側面型１２ａは内側面当接部１２ｄから型内方に突出するように形成される。   As shown in FIG. 3, the engaging portion 12 b has a plate-like upper surface abutting portion 12 c that abuts on the upper surface of the outer frame 11, and a plate-like shape that is formed perpendicular to this and abuts on the inner surface of the outer frame 11. The side surface mold 12a is formed so as to protrude inward from the inner surface contact part 12d.

また、係合部１２ｂは、ボルト、万力、マグネットなどにより外枠１１に仮に固定され、これにより型材１２が外枠１１に装着される。   Further, the engaging portion 12b is temporarily fixed to the outer frame 11 with a bolt, a vise, a magnet or the like, whereby the mold material 12 is attached to the outer frame 11.

以下、型枠Ｋを用いてコンクリート板Ｗを製造する手順を説明する。   Hereinafter, a procedure for manufacturing the concrete plate W using the mold K will be described.

手順１：コンクリート板Ｗの形状、寸法に合わせて定盤１上に外枠１１を設置する（図２参照）。なお、この手順１は、同サイズのコンクリート板Ｗを製造する場合には、１枚目のコンクリート板Ｗを製造するときにのみ実行されるものであり、２枚目以降の製造においては省略される。   Procedure 1: The outer frame 11 is installed on the surface plate 1 in accordance with the shape and dimensions of the concrete plate W (see FIG. 2). In addition, this procedure 1 is performed only when manufacturing the first concrete board W, when manufacturing the concrete board W of the same size, and is abbreviate | omitted in the manufacturing after the 2nd sheet. The

手順２：型材１２を外枠１１に装着する（図１の状態）。これにより型枠Ｋが形成される。   Procedure 2: The mold material 12 is mounted on the outer frame 11 (state shown in FIG. 1). Thereby, the formwork K is formed.

手順３：コンクリートを型枠Ｋ内に打設する。   Procedure 3: Place concrete in formwork K.

手順４：所定期間の養生後、係合部１２ｂに施された仮固定を解除し、コンクリート板Ｗを型材１２とともに吊り上げる（図３の状態）。   Procedure 4: After curing for a predetermined period, the temporary fixing applied to the engaging portion 12b is released, and the concrete board W is lifted together with the mold material 12 (state of FIG. 3).

手順５：美装工程場などにコンクリート板Ｗを搬入し、型材１２をコンクリート板Ｗから取り外す（図４参照）。   Procedure 5: The concrete board W is carried in to the dressing process place etc., and the mold material 12 is removed from the concrete board W (refer FIG. 4).

なお、同一サイズのコンクリート板Ｗを製造する場合は、手順２〜６が繰り返されて次のコンクリート材Ｗを製造がなされる。   In addition, when manufacturing the concrete board W of the same size, procedure 2-6 is repeated and the next concrete material W is manufactured.

このように、実施形態においては、コンクリート板Ｗの側面形状を所望形状に形成する側面型１２ａを有する型材１２が、定盤１に固定された外枠１１からコンクリート板Ｗとともに離脱できるような状態で外枠１１に装着され、これにより型枠Ｋが形成される。したがって、側面に溝を形成する場合のように、通常は側枠を移動させなければ養生後のコンクリート材Ｗを脱型し得ない場合においても、側枠を移動させることなく脱型することが可能となる。このため、一定サイズのコンクリート材Ｗを複数枚製造するような場合には、１枚ごとに位置決めをして定盤に型枠を設置する必要がなくなり、工程数およびその所要時間が削減される。   As described above, in the embodiment, the mold material 12 having the side surface mold 12a that forms the side surface shape of the concrete plate W into a desired shape can be detached from the outer frame 11 fixed to the surface plate 1 together with the concrete plate W. Is attached to the outer frame 11 to form the mold K. Therefore, it is possible to remove the mold without moving the side frame even when the concrete material W after curing cannot be demolded unless the side frame is usually moved as in the case of forming a groove on the side surface. It becomes possible. For this reason, in the case of manufacturing a plurality of concrete materials W of a certain size, it is not necessary to position each one and install a mold on the surface plate, thereby reducing the number of steps and the time required for the steps. .

また、同一サイズのコンクリート材Ｗを複数枚製造するような場合には、外枠１１は固定したままで、次々にコンクリート材Ｗを製造できるので、個体差を抑えて寸法精度を向上させることができる。   Further, when a plurality of concrete materials W of the same size are manufactured, the concrete material W can be manufactured one after another while the outer frame 11 is fixed, so that the dimensional accuracy can be improved by suppressing individual differences. it can.

また、模様板用の型枠のように、側枠と面型とが一体化された型枠においても溝を形成するなど、側面を所望形状に形成することが容易となる。   Moreover, it becomes easy to form a side surface in a desired shape, such as forming a groove even in a mold frame in which a side frame and a surface mold are integrated like a pattern plate mold.

また、コンクリート板Ｗの側面形状を、仕様（例えば、オープンジョイント仕様、シーリング仕様）に応じて変更する場合にも、図５に示すように、対応する断面形状の側面型１２ａ１、１２ａ２を有する型材１２Ａ、１２Ｂを外枠１１に装着するだけでよく、側面形状の異なる一定サイズのコンクリート材Ｗを製造する場合に、その作業効率を著しく向上させることができる。 Furthermore, the side shape of the concrete plate W, specifications (e.g., open joint specification, sealing specification) even when changing depending on, as shown in FIG. 5, a side type 12a 1 of the corresponding cross-sectional shape, the 12a 2 It is only necessary to attach the mold materials 12A and 12B to the outer frame 11, and when manufacturing a concrete material W having a constant size and a different side shape, the working efficiency can be remarkably improved.

なお、コンクリート板Ｗは、ＰＣ板に限らず、ＧＲＣ（ガラス繊維補強セメント）板、ＶＦＲＣ（超軽量コンクリート）板とされてもよい。   The concrete plate W is not limited to a PC plate, and may be a GRC (glass fiber reinforced cement) plate or a VFRC (very lightweight concrete) plate.

本発明は、側面に溝などを有するコンクリート板の製造に適用できる。   The present invention can be applied to the production of a concrete plate having a groove or the like on the side surface.
