Method for manufacturing construction material and structure thereof

Structure of construction material comprising a middle wooden raw material and a left and a right raw wooden materials connected with opposite two sides of the middle raw wooden material, wherein:

• the middle raw wooden material is cut along fiber direction thereof to form cutting faces with predetermined length and shape;
• and
• the left and right middle raw wooden materials are cut along fiber direction thereof to form cutting faces with predetermined length and shape, each of the left and right raw wooden materials having a cutting face with a shape corresponding to the shape of any cutting face of the middle raw wooden material, the corresponding cutting faces of the left and right raw wooden materials being fixedly connected with two opposite cutting faces of the middle raw wooden material, said structure being characterized in that the middle and left and right raw wooden materials are taken from different trees.
