Abstract:
Provided are: a structural laminated veneer lumber that is of a novel configuration and that can be used as a structural material; and a method for producing same. This structural laminated veneer lumber is obtained by stacking thin layers of veneers 11, 12 vertically on one another via an adhesive 13. Used as the veneers are veneers 12 each formed from a high-density tree species having an air-dried specific gravity of 0.5 or more and veneers 11 each formed from a low-density tree species having an air-dried specific gravity of less than 0.5. Upper and lower surface layers 21 are disposed so at to constitute surface sides of a structural laminated veneer lumber, whereas an intermediate layer 22 is disposed between the upper and lower surface layer 12.
