で完了し、作業能率を高めることが可能である。Therefore, it is possible to provide a structural laminated timber with excellent bending properties and shear properties even if it has a small cross section. Furthermore, since the through-holes are formed after a plurality of wooden laminas and bending reinforcing plates are assembled and bonded, bonding of the laminas can be completed in one go, making it possible to increase work efficiency.

うな必要がなく、作業能率を高めることが可能である。In addition, in the method for manufacturing structural laminated timber according to claim 2, the lamina is laminated and bonded while inserting a shear reinforcing material into the hole, so that the bending properties and shearing properties of the structural laminated timber are improved. It is possible to increase Therefore, it is possible to provide a structural laminated timber with excellent bending properties and shear properties even if it has a small cross section. Furthermore, holes are formed in each of the multiple wooden laminas and bending reinforcing plates, and while inserting shear reinforcement into the holes, the wooden lamina and bending reinforcing plates are stacked and glued together, so wait for the adhesive to harden. There is no need to do this, and it is possible to improve work efficiency.
