It comprises a protective layer 4 formed on the fiber reinforced plastic 3. The formwork and finishing material 1 is a member that is integrated with the concrete 5 and left as a surface finishing material without being dismantled.

<B> Resin Member The resin member 2 is a member that comes into contact with the concrete 5 to be cast on one side and fixes the other side to a fiber-reinforced plastic 3 described later. As the resin member 2, it is preferable to use a material having good adhesion to the concrete 5, and for example, a known lightweight resin such as styrene foam may be used. In addition, by employing a lightweight resin such as styrene foam, the weight of the formwork and finishing material 1 itself can be reduced, and the handleability is improved. The resin member 2 has a side surface in contact with the concrete 5, in addition to improving the adhesiveness to the concrete 5 by the material, has a wavy shape,
By providing various shapes (not shown) such as hooks, it is possible to further improve the adhesiveness. On the other hand, it is conceivable that the side surface that comes into contact with the fiber reinforced plastic 3 has a shape that matches the side surface shape of the fiber reinforced plastic 3 so that the side surface is firmly fixed.
The resin member 2 is made of a material that absorbs an impact from the fiber reinforced plastic 3 and has a function of buffering an external force acting on a concrete building.

<C> Fiber Reinforced Plastic The fiber reinforced plastic 3 is a member serving as a reinforcing frame for the resin member 2 attached to the side surface of the resin member 2 described above, and adds desired shaping to the surface of the concrete 5 to be cast. It is also a member for. For details, see Fiber reinforced plastic 4

This is a member for imparting modeling beauty to the appearance of a concrete building. The fiber reinforced plastic 3 is a known F.R. R. P. Since it is a material having high strength and excellent workability, it is possible to add a free molding beauty to the surface of the concrete 5. The shape to be added to the concrete structure is not limited to the circular convex shape shown in the figure. For example, it is conceivable to adopt various designs such as embossing and displaying the name of the structure or adding various patterns. Can be

<D> Protective Layer The protective layer 4 is a protective member that covers the fiber reinforced plastic 3 described above. The fiber reinforced plastic 3 is deteriorated by being exposed to wind and rain, and its strength is reduced. Therefore, it is conceivable to form the protective layer 4 to prevent the fiber reinforced plastic 3 from deteriorating and to provide further strength. As the protective layer 4, for example, a known coating material such as a concrete deterioration preventing material, a metal anticorrosive, and elastic concrete, or a finishing material is sprayed and applied to be disposed in a layer on the surface of the fiber reinforced plastic 3. Can be considered. It is also conceivable to add a more beautiful appearance to the appearance of the concrete structure by coloring the known member, which will be the protective monk 4,.

At this time, the mold and finishing material 1 is formed in advance so that a desired shape can be given to the surface of the concrete building, and the protective layer 4 is formed on the surface of the fiber-reinforced plastic 3. Have been. Therefore, the fiber reinforced plastics 3 group located on the outer peripheral surface of the formwork and finishing material 1 group is the outer peripheral surface of the completed concrete building.
It is needless to say that the formwork and finishing material 1 can be erected from the resin member 2 side, which is the back surface, by known means via a separator (not shown) or the like. It is also conceivable to improve the connectivity between the members by forming a concavo-convex connecting portion (not shown) or the like at the connecting end of the formwork and finishing material 1.

<B> Concrete Casting Step Concrete 5 is cast between the formwork composed of one group of the assembled formwork and finishing material. Resin member 2 of formwork and finishing material 1
Is in contact with the cast concrete 5 and adheres to the concrete 5 with a high adhesive force.
At this time, if various shapes such as a wavy shape and a hook shape are formed on the surface of the resin member 2, the surface area in contact with the concrete 5 increases and the adhesiveness increases accordingly. The concrete 5 thus cast and the resin member 2 are integrally attached to each other, and the formwork and finishing material 1 is positioned on the outer periphery of the concrete structure. Therefore, if the concrete 5 is cast and cured, the concrete building is completed without any dismantling or removal of the formwork.
