WARPAGE PREVENTION STRUCTURE FOR PREVENTING WARPAGE OF PLATE CONSISTING OF WOOD OR WOODY MEMBER AND WARPAGE PREVENTION METHOD

摘要

To provide a warpage prevention structure having an excellent persistence in a warpage prevention effect, a warpage prevention method and a warpage prevention member.SOLUTION: A warpage prevention member 10 consisting of a reinforcement fiber plastic and formed extending in one direction is joined to a plate 2 by an adhesive agent 23 along a desired direction in which a warpage can be generated in the plate 2. In the warpage prevention member 10, a flange part in plate shape 12, and a web part in plate shape 11 erected from the flange part 12 and buried orthogonal or diagonal to the plate 2 resisting against shearing force generating on the plate 2 are formed along one direction. The web part 11 is buried orthogonal to the plate 2 and joined to the plate 2 by the adhesive agent 23.SELECTED DRAWING: Figure 2
