型枠用板材が開示されている。2. Description of the Related Art As a conventional plate material for a concrete formwork, a wooden plywood or a metal plate is known. The weight of such a plate material for a concrete form increases as the size of the building increases, and the workability deteriorates.
Therefore, for the purpose of reducing the weight of the concrete form, there have been proposed some concrete form plates using a light high-foam resin as a core material and integrally providing resin sheet layers on both surfaces thereof. For example, Japanese Unexamined Utility Model Publication No. 7-25114 discloses a laminated board material in which a thermoplastic resin foam is used as a core material, and a resin sheet layer in which glass fibers are arranged in a specific direction is provided on both surfaces thereof. Japanese Patent Application Laid-Open No. 8-93217 discloses a plate for a concrete formwork in which a urethane foam resin is used as a core material and a resin sheet layer made of polypropylene mixed with glass fibers is provided on both surfaces thereof.
Further, Japanese Patent Application Laid-Open No. Hei 8-100523 discloses that a block made of a foamed resin such as styrene foam resin is used as a core material, the inner layer portion of the core material is made to have high foaming, and the surface layer portion is made to have low foaming. A plate for concrete formwork containing fibers is disclosed.

る。[0003] However, since the above-mentioned conventional plate material for concrete form uses glass fiber,
There are the following problems. (I) The plate material for the concrete formwork containing the glass fiber becomes harder and harder to nail. (Ii) If the plate material for the formwork is cut into a desired shape by, for example, a circular saw, the dust of the glass fiber is scattered, which adversely affects the human body. Also, glass fiber often damages the saw teeth. (Iii) Aggregates contained in the concrete may cause the surface of the plate for the form to be worn when the ready-mixed concrete is poured into the form. In this case, the glass fiber exposed on the worn surface has an affinity for the concrete. For this reason, the plate material for the formwork and the concrete adhere to each other, and the release operation becomes difficult. (Iv) In recent years, there has been a demand for recycling of used resins due to the increasing awareness of global environmental protection. However, resins containing glass fibers are practically difficult to recycle. (V) Molds that do not use glass fiber, such as those made of polypropylene or polystyrene, have the drawback that nails are easily pulled out when nailed.
