Abstract (en)
The invention provides a board for a concrete form panel. The board 1 comprises: a core plate 2 formed of a first synthetic resin material and having both side surfaces; and a pair of skin layers 3 formed of a second synthetic resin material and provided on and covering the both side surfaces of the core plate 2. Stiffeners 5 are secured to the board 1 by means of nails 6 hammered in the board 1 to form a concrete form panel 4. The first synthetic resin material for the core plate 2 is cellular such that the core plate 2 provides good hold of the nails 6. The skin layers 3 have water-impermeability and strippability from a surface of formed concrete. The first synthetic resin material for the core plate 2 and the second synthetic resin material for the skin layers 3 have substantially the same composition. <IMAGE>
