The flash panel which designates the expansion and contraction possible ligneous structure and the particular ligneous structure as the core material

摘要

Topic Although it uses as the core material of the flash panel being the ligneous structure which is suited, as it is superior in strength and handling characteristic, bond strength of the face bar can be high, reinforce the face bar sufficiently, reuse of the scrap wood offers the possible ligneous structure. SolutionsExpansion and contraction possible ligneous structure 1, board backing material 2 of the belt shape which consists of the ligneous material, opposing the board surface, large number laminate, being parallel to the cross direction of the board backing material, the time when it opens to the surface or the underside of the board backing material the groove 3 for tune with the flexible seat 4 which sticks on the board surface of the plural providing and opposite side, bend the both sides of the groove 3 for the time tune in the aforementioned board backing material and 2 possibly connect, at the same time, opening of the groove 3 for all times way tune, it is opposite side to crookedness direction, the groove 3 for the time tuneGluing place of opening direction and board backing material 2 is formed.
