板を含むものとする。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a concrete formwork having a flexible part, and a formwork which has a bendable part on the concrete molding surface but does not cause streaks on the surface of the concrete product corresponding to the bending part. The purpose is to provide. In this case, formwork includes templates for on-site assembly.

いる。For example, square cylindrical concrete products such as boxes and culverts are manufactured using 1. When crushing the mold to produce a product, the gap between the outer mold and the inner mold is filled with concrete IJ, and when demolding the product,
The outer mold opens outward and the inner mold collapses inward to remove the product. For this reason, a part of the inner mold is separated, and when removing the mold, it is pulled inward and the instant welding part is placed next to it, thereby shrinking the three sides inward. The method used is to refract the light to bring the two adjacent surfaces inward.

を阻害していた。また製品表面に必ず合せ目の条痕を生
じ、これを除去する作業が加わる事も少くながった。In either method, the inner mold is divided into several parts, and when filling with concrete, the divided parts are brought into close contact with each other, and when demolding, the divided parts are opened and operated for demolding. Since concrete with good fluidity is poured, some of the concrete invades the joints of the parts that were supposed to be in close contact, and this solidifies as it cures. As this process was repeated to mass produce products, the cleaning of concrete that stuck and accumulated at the joints hindered the efficiency of formwork assembly work. In addition, there are fewer seam lines that always appear on the surface of the product, and the need to remove them has been reduced.
本発明者は、成形面を分断しておいて、型組時、完全に
密着させるという従来の思想を捨て、成形面自体を屈折
可能にするという着想を得た。The present inventor abandoned the conventional idea of dividing the molding surface and bringing them into perfect contact during mold assembly, and came up with the idea of making the molding surface itself bendable.
そして、成形面の屈折が必要な位置をゴム等の可撓板で
借成し、この可撓板を屈折可能な補強板により裏当てし
、これを隣接成形面の銅板に固定して、これを支持させ
たのである。Then, a flexible plate made of rubber or the like is used to fill the position where bending is required on the molding surface, this flexible plate is backed by a bendable reinforcing plate, and this is fixed to the copper plate on the adjacent molding surface. was supported.
次に図面を参照して、この発明の構成、実施態様を説明
する。Next, the configuration and embodiments of the present invention will be described with reference to the drawings.
第1図はこの発明を適用した角筒形コンクリート製品量

It moves parallel outward with /c attached, but this is not particularly different from the conventional method.

ート型枠になっている。In this case, the features of this invention appear in the inner mold. In other words, a part of the forming surface mainly composed of steel plates is connected to the adjacent steel plate B (2c) without a step.
The flexible plate 3 is fixed to the non-molded surface side with a reinforcing plate (hinge lI) that can be bent around its longitudinal direction as a backing, and both sides of the reinforcing plate (hinge lI) The edge is a concrete formwork with a flexible portion that is fixed directly or indirectly to the non-forming surface side of both adjacent steel plates B (-C).

Of these, Ah, 2c has a part of its molded surface as a flexible plate, in this example a rubber plate 3. refraction axis B
is located in the center of each of the side plates b and 2c, so the steel plate is divided into left and right parts, with a rubber plate 3 inserted in the center. Of course, on the forming surface that contacts the concrete, the steel plate part and the rubber plate part are connected smoothly, and since the rubber plate 3 is thicker, it protrudes to the back side accordingly.

。Figures 3 and 4 show enlarged cross sections, and the wing plate α of the hinge fixed to the outer surface of the rubber plate 3 with screws (or fixed with adhesive) is the total length of the rubber plate 3, that is, the height of the inner mold side plate Zb. Since it is a belt-shaped steel plate having the same overall length, it is backed with reinforcing channel steel ttb. A bracket is attached to each of the channel steel titb on both sides, and the shaft k is passed through it to form a hinge. The blade group α and the side plate 2b, which is an adjacent steel plate, are indirectly fixed by welding via an intervention plate t that fills the step difference between the rubber plate 3, the side plate, and 2b.
第4図にゴム板3を含む側板コbを少し折曲げた状態を
示す。ゴム板3は蝶番ダの左右翼板ダα。FIG. 4 shows a state in which the side plate b including the rubber plate 3 is slightly bent. Rubber plate 3 is the left and right wing plate α of the hinge.

残すおそれがない。Since both sides of the refraction axis B are lined by α,
There is no risk of irregular deformation or damage such as twisting due to the bending action. In other words, even if the weak rubber plate 3 is added, the strength of the side plate is not impaired, and the surface of the bent part is always smooth, so there is no risk of leaving a sales mark on the surface of the product.

ら離れた位置をくわえて運び出してもよい。Next, a simple handling explanation of the embodiment shown in FIGS. 1 and 2 will be given. As shown by the solid line in Figure 1, pouring concrete from above into the gap between the assembled outer mold side plate lα~/d and the inner mold side plate 2a''M and curing it is the same as before. Open the side plates /b and /c as usual and open the side plate 1d.
The outer surface of the molded concrete is opened by moving in parallel, but the inner mold bends the side plates 2b and 2b inward.
The threaded rod 7 passed through the center of the formwork is turned with a handle to move the female screws 9, 9 to which the left and right links 10 are attached. As a result, each hinge axis qc is simultaneously pulled inward via the link 10, and the side plates -b, 1g are bent inward as shown by the chain lines in FIG. Note that when the side plates b and 2c are bent at their respective centers, the corner portions at both ends of the adjacent side plates b and d are slightly bent. The entire inner mold can now be extracted upwards using a crane. The shaped concrete product is then similarly removed by a crane. Alternatively, you may leave the inner mold as it is and immediately carry it out by holding the product at a position away from the inner mold side plates 2b, 2.

施条件に合わせて設計すればよい。The present invention has been explained above using an example in which it is applied to a forming form for prismatic cylindrical concrete products, but this invention changes the molding surface of various concrete forms and templates which have always been rigid. It has a flexible surface that is partially reinforced to be bendable, and can be varied and applied in a variety of ways depending on the implementation conditions without changing its gist. For example, FIGS. 5 to 7 show the three-dimensional side where the backing reinforcing plate of the flexible plate 3 is not a hinge. In Fig. 5, the molding surface between adjacent steel plates ii and ti is made of a flexible plate 3 made of rubber, and the reinforcing plate DA' that backs it is also made of an integral rubber plate, and both edges are formed by adjacent steel plates 1/, This is an example in which it was glued to 11. The reinforcing plate "Hiroshi" in Fig. 6 is a flexible thin metal plate, to which the rubber plate 3 is glued, and both edges are attached to adjacent steel plates.
, is attached to //. In Fig. 7, like Fig. 5, a thick rubber plate serves as both the flexible plate 3 and the reinforcing plate DA'.
This is an example in which the refraction axes are arranged in parallel at several locations. other than this,
The flexible plate 3 may be made of a material other than rubber, or a reinforcing plate +,
It may be designed according to the implementation conditions, such as by variously changing the combinations with lI' and 4('.

、現場組立用鋼製型板も自由な角度に屈折して使える。Including the above-mentioned embodiments, the formwork in which the molding surface was divided because the shape of the molding surface was not suitable for demolding is simplified by this invention, and it is possible to produce a wide variety of products in small quantities in which only a part of the product or the bending angle changes. With this invention, the formwork for the product can be designed to be used for multiple purposes, and the steel template for on-site assembly can also be bent at any angle and used.
