Bamboo laminated lumber and method for manufacturing

Bamboo laminated lumber, comprising at least one bamboo laminated lumber element having top and bottom surfaces being

• a first linear bamboo starter board, having ends and top and bottom surfaces and a longitudinal centerline, being two flattened timber bamboo culm halves each having a soft pith surface and a hard cutaneous cortex surface and longitudinally parallel grain with the respective soft pith surfaces adhered together and the grain of each halve arranged to align with the linear bamboo starter board longitudinal centerline,
• a middle layer, having top and bottom surfaces and a longitudinal centerline, comprising at least one first middle starter board, having ends and top and bottom surfaces, being two flattened timber bamboo cane halves each having a soft pith surface and a hard cutaneous cortex surface with the respective soft pith surfaces adhered together with the grain of each halve arranged with the grain opposingly offset from the first middle starter board centerline at a first preselected angle selected from the range of 2 to 12 degrees, the top of the middle layer adhered to the bottom surface of the first linear bamboo starter board with the middle layer longitudinal centerline aligned with the grain of the first linear bamboo starter board, and,
• a second linear bamboo starter board, the top of the second linear bamboo starter board adhered to the bottom surface of the middle layer with the grain aligned to the first linear bamboo starter board grain whereby the first and second linear bamboo starter boards and middle layer respective alignment facilitates resistance to longitudinal bolt pullout.
