えないという難点がある。 Conventional boards for concrete formwork are mainly made of plywood as is or with paint applied to the contact surface of the plywood, but when used in formwork, it is difficult to separate the boards after concrete is poured. Due to poor formability, the concrete may stick to the board, or if it is painted, the paint may stick to the concrete, resulting in not only a poor finish of the poured concrete, but also a large number of repetitions. The problem is that it cannot withstand use.
この点に鑑み、型枠用の基板に接着剤を介する

久性（反復使用）の面で問題がある。 In view of this, a formwork panel has been proposed in which a polyolefin thermoplastic resin film is adhered to a formwork substrate by hot pressing without using an adhesive. There are problems in terms of durability (repeated use) because the degree of adhesion is difficult to be uniform and the strength of the film is not high.

特徴とするものである。 The present invention was developed with the aim of providing a board for concrete formwork that does not have the drawbacks of conventional products as described above.The structure consists of a board made of plywood, etc., with polyester bonded to one side of the board through an adhesive layer. It is characterized by forming a synthetic resin film layer such as film, fluororesin film, or polycarbonate film that has good weather resistance, mold release properties, and is hard to scratch, and then applying silicone coating to the surface of the film layer. be.
次に本考案の実施例を図に拠り説明する。 Next, an embodiment of the present invention will be described with reference to the drawings.

イルム層である。 In Fig. 1, 1 is a board made of plywood, etc.;
is formed on one side of the substrate 1 with an adhesive layer 3 interposed therebetween.
The film layer has good weather resistance and mold release properties, and is relatively scratch-resistant.

型枠用の板に比し、数倍の反復使用に耐られる。 Therefore, the film layer 2 in the above is usually
A polyester film, a fluororesin film, or a polycarbonate film is formed by thermocompression bonding with an adhesive layer 3 interposed therebetween. The reason for interposing the adhesive layer is to ensure that the film adheres to the entire surface of the substrate even if the substrate 1 has an uneven surface. Also,
The above-mentioned films used for this film layer 2 have good weather resistance, mold releasability, and are hard to damage, so if this film layer 2 is used as a contact surface for concrete, the film layer 2 Even if concrete adheres to the surface, it is not easily damaged, and therefore, when the formwork is removed after the concrete has hardened, it can be peeled off without tearing. In addition, as mentioned above, the film layer 2 is weather resistant, so there is no risk of deterioration during storage when not in use. It can withstand repeated use several times over.

ができる。 In order to form the film layer 2, a layer of polyester film, fluororesin film, polycarbonate film, etc. is laminated in advance on a film with good thermocompression bonding properties, and this is laminated onto the plate 1.
By placing it on top of the plate and attaching it by thermocompression bonding, the concrete formwork plate of the present invention can be obtained very easily.

とができて経済的でもある。 The present invention is as described above, and a film layer with good weather resistance, mold releasability, and scratch resistance is formed by using polyester film, fluororesin film, or polycarbonate film via an adhesive layer on one side of a substrate made of plywood or the like. Since this film layer is coated with silicone, when used as a formwork for concrete pouring work, it has good release properties and the extent to which concrete adheres to the film layer is better than that of conventional formwork. Since the amount is significantly reduced compared to , the concrete has a good finish, and the film layer has excellent weather resistance and is not easily damaged, so it can withstand repeated use many times and is economical.
