To provide a concrete form material which is repeatedly usable and contributes to preservation of wood resources and an environment.
The concrete form is formed by providing a sheathing board 1 made of plywood or a paperboard, mounting a frame 2 on a rear side of the sheathing board 1 along the periphery of the same, and arranging aluminum crosspieces 3 inside the frame 2. Each aluminum crosspiece 3 is formed by arranging a pair of support strips 33 abutting on the rear side of the sheathing board 1, on both sides of each projecting bar 30, in a manner extending along the same. The cross piece is formed of aluminum, and therefore it is very high in durability, which leads to repeated use of the concrete form. Further, the concrete form is large in pressure resistant strength, and the plywood and the paperboards are advantageously thin in thickness as the sheathing board, which leads to reduction of use of building materials, to thereby contribute to preservation of wood resources and an environment.
