【考案の詳細な説明】
本考案は、コンクリート成形品等の成形体の成形に用い
られる型枠装置に関するもので、成形体の離型を容易に
するものである。[Detailed Description of the Invention] The present invention relates to a formwork device used for forming a molded object such as a concrete molded product, and facilitates the release of the molded object.
コンクリート成形品等の成形体と成形に用いられる型枠
は、離型が容易であること及び成形体の強度が低強度の
段階で離型が可能であることが望ましい。It is desirable that a molded product such as a concrete molded product and a formwork used for molding be easily releasable from the mold and that the molded product can be released from the mold at a stage where the strength of the molded product is low.
然し乍ら、一般に、離型時には、相当大きな離型力を要
するため、成形体の離型面及び成形体全体に過剰な力が
加わり易く、従って、離型面及び成形体に損傷を与え易
い。However, in general, when releasing from the mold, a considerably large mold release force is required, so excessive force is likely to be applied to the mold release surface of the molded article and the entire molded article, and therefore, the mold release surface and the molded article are likely to be damaged.
また、このような損傷は、成形体の強度が低強度の段階
で離型した場合に特に生じ易い。Furthermore, such damage is particularly likely to occur when the molded article is released from the mold at a low strength stage.
本考案は、離型が容易で且つ成形体の強度が低強度の段
階でも離型可能な型枠装置を提供するものである。The present invention provides a molding device that is easy to release from the mold and can be released even when the strength of the molded product is low.

・・・・を並列結合して形成しであるものである。In other words, the formwork device of the present invention makes it possible to release the formwork sequentially from the end of the molded product without using batch release, and allows the mold release to be performed by dispersing the mold release force caused by batch release. It has a flexible formwork 2, a tube mat 1 that expands and contracts with the light sharpening of the fluid (i.e., energy or degassing, and light waves or liquid removal), and a rigid back-up material 3. ,
The tube mat 1 is made up of a plurality of tubular hollow bodies 11, 11, which can be independently invigorated and degassed.
It is formed by connecting ... in parallel.
以下、本考案の型枠装置を、図面に、その使用態様と共

上記チューブマット１は、それぞれ独立して元気及び脱
気が可能な複数個のチューブ状中空体１１．１１・・・
・・・を並列結合して形成しである。The tube mat 1 is made up of a plurality of tubular hollow bodies 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 11, 20, 35, 34, 35, 40, 40, 40, 40, 40, 30, 34, 3, 3, 3, 3, 3, 3, 4, 4 different hollow bodies 11, 11, 11.
It is formed by connecting ... in parallel.
即ち、各チューブ状中空体１１は、何れも図面に対して
垂直方向に延びており、結合材１２．１２・・・・・・

。The tubular hollow bodies 11 are filled with air through pipes 13, respectively.
However, when the tubular hollow body 11 is made of a non-stretchable sheet, degassing is carried out by supplying air with a pump (not shown) or the like through the tubular hollow body 11. If the tubular hollow body 11 is made of an elastic material, by opening the evacuation port of the tubular hollow body 11, the air will be naturally evacuated due to the contractile force of the elastic material.
しかし、弾性材の材質の差異により強制的に脱気する必
要もある。However, due to the difference in the quality of the elastic material, forced degassing may be necessary.

次に、上記構成からなる本考案装置の一使用態様につい
て第１図〜第４図に基づき説明する。Next, one mode of use of the device of the present invention having the above configuration will be explained based on FIGS. 1 to 4.
先ず、本考案の型枠装置のチューブマット１を形成する
各チューブ状中空体１１に元気（通常空気が用いられる
）した後、型枠２を所定位置に配置してバックアツプ材
３を固定する。First, after each tubular hollow body 11 forming the tube mat 1 of the formwork device of the present invention is energized (usually air is used), the formwork 2 is placed in a predetermined position and the backup material 3 is fixed. .
この手順は、型枠２を所定位置に配置できれば適宜変更
しても良い。This procedure may be changed as appropriate as long as the formwork 2 can be placed in a predetermined position.
このようにして、本考案の型枠装置、及び必要に応じて
他の型枠を用いて目的とする成形体の形状に応じた枠組
みを行なう。In this way, the molding device of the present invention and other molds as necessary are used to form a molded article according to its shape.
次いで、型枠内にコンクリートモルタルその他の無機又

る（第１図参照）。Next, the mold is filled with a molding material 4 made of concrete mortar or other inorganic or organic casting material (see FIG. 1).
成形材料が−・定強度を発揮する迄固化した後、離型作
業を開始する。After the molding material has solidified to a point where it exhibits a certain strength, the mold release operation begins.

側端部（図上下端）のチューブ状中空体１１の脱気を行
なう丈で良く、その結果、成形材料４の固化した成形体
は、型枠２から容易に離型する。In the device of the present invention, this mold release work is carried out at one end of the tube mat 1 (upper end in the figure), as shown in FIGS. 2 to 4.
It suffices to start deaerating the tubular hollow body 11 at the end, and then sequentially deaerate the tubular hollow body 11 at the other end (upper and lower ends in the figure), and as a result, the solidified molded body of the molding material 4 is easily released from the mold 2.
即ち、本考案装置によれば、−側端部のチューブ状中空

１の収縮により、該中空体１１及び型枠２はバックアツ
プ材３側に引寄せられる。That is, according to the device of the present invention, when the tube-shaped hollow body 11 at the negative side end is degassed, the formwork 2 and the back-up material 3 are connected and fixed to the hollow body 11, and the back-up material 3 is fixed to the hollow body 11. The material 3 has high rigidity and is fixed at a predetermined location (not shown), and the formwork 2 has flexibility, so the tubular hollow body 1
1, the hollow body 11 and the formwork 2 are drawn toward the back-up material 3.
その結果、例えば、大気圧Ｐ。と中空体１１内の流体圧
Ｐ２との差Ｐ。As a result, for example, atmospheric pressure P. and the fluid pressure P2 inside the hollow body 11.
−Ｐ２が、型枠２と成形材料４の固化した成形体との付
着力Ｐ１より大になると、型枠２はその一端から屈曲性
を有するため、屈曲し乍ら徐々に離型して行く。- When P2 becomes larger than the adhesion force P1 between the formwork 2 and the solidified molded body of the molding material 4, since the formwork 2 has flexibility from one end, it gradually releases from the mold while being bent. .
従って、−側端部の中空体１１から順次脱気（Ｐ２を小
にする）して行けば、それに応じて型枠２は成形体から
離型される。Therefore, if the air is sequentially removed from the hollow body 11 at the negative end (by reducing P2), the mold frame 2 will be released from the molded body accordingly.
そして、この際の離型は、一般の離型における如く、型
枠全面による一括離型ではなく、例えば、型枠と成形体
との離型面において線状部又は点状部で離型され、且つ
離型力Ｐ。The mold release at this time is not a one-shot mold release using the entire surface of the mold as in general mold release, but, for example, mold release is performed at linear or dotted portions on the mold release surface between the mold and the molded product. , and the mold release force P.
Ｐ２は徐々に増大されていき、型枠と成形体との付着力
Ｐ１を僅かに超せば離型するから、離型は、最少の離型
力を離型面の一端から徐々に加える丈でなし得る
成上の如く、本考案装置によれば、成形体の離型に際し
、最少の離型力で済むため、離型が容易であり、且つ比
較的成形体が低強度の段階でも損傷を生ずることなく離
型可能であり、しかも離型時に特別な労力を要しないか
ら、効率良く離型作業を実施できる。P2 is gradually increased, and the mold is released when it slightly exceeds the adhesion force P1 between the mold and the molded body, so the mold release is performed by gradually applying the minimum mold release force from one end of the mold release surface. As shown in the above, the device of the present invention requires only a minimum of releasing force when releasing the molded product, making it easy to release the mold and preventing damage even when the molded product has relatively low strength. Since the mold can be released without causing any damage and no special effort is required during mold release, the mold release work can be carried out efficiently.
