PROBLEM TO BE SOLVED: To provide a corner material for construction capable of beautifully finishing a finishing surface of a putty by projection of a corner part, easily winding in a roll shape in a flatly expanded state, hardly causing dislocation between the inside and the outside of a roll, and capable of stably holding a shape of winding in the roll shape.SOLUTION: In a corner material 1 for construction having a hinge part 3 and belt-like plate parts 2 and 2 on its both sides, an angle-shaped projection part 30 projecting from a surface of the hinge part 3, is formed on the surface side of the hinge part 3, and a first recessed part 31 recessed in an angle shape from a reverse surface of the hinge part 3 and having a size capable of storing the projection part 30, is formed on the reverse surface side of the hinge part 3, and a second recessed part 32 is formed by recessing an apex part of the projection part 30, and when bending the plate parts 2 and 2 by the hinge part 3, a bottom part of the second recessed part 32 protrudes, and forms a projection 33 projecting on a surface of the hinge part 3.SELECTED DRAWING: Figure 2 |
