Bamboo laminated construction panel and method of manufacture
A bamboo laminated construction panel and method of manufacture is provided wherein at least two layers of prepared bamboo are laminated together with outside surface wood veneer layers. Linear bamboo starter boards, made from timber bamboo culm cut to length, split longitudinally, processed to remove sugars, pressed flat into bamboo planks with the soft pith surfaces of two bamboo planks laminated together with grain aligned, are disposed adjacent to each other along the longitudinal side edges forming a linear bamboo starter board layer. The bamboo laminated panel is formed by laminating a first wood veneer layer with grain disposed perpendicular to the vertical centerline of the finished panel, first and second bamboo starter board layers with grains aligned opposingly and equally offset from the centerline, and a second wood veneer layer with grain also perpendicularly aligned. Additional bamboo starter board layers are optionally included in pairs to form thicker panels.
1. A bamboo laminated construction panel comprising layers of wood veneer and linear bamboo starter boards laminated together with an adhesive forming the panel having a longitudinal vertical centerline, the layers being
a first wood veneer layer having top and bottom surfaces and a longitudinal grain, the first wood veneer layer being disposed with the longitudinal grain oriented perpendicular to the longitudinal vertical centerline of the panel,
a first bamboo starter board layer, having top and bottom surfaces and a longitudinal grain, disposed with the top surface adhered to the bottom surface of the first wood veneer layer,
a second bamboo starter board layer, having top and bottom surfaces and a longitudinal grain, disposed with the top surface adhered to the bottom of the first bamboo starter board layer; and,
a second wood veneer layer having top and bottom surfaces and a longitudinal grain, disposed with the top surface adhered to the bottom surface of the second bamboo starter board layer with the longitudinal grain oriented perpendicular to the longitudinal vertical centerline of the panel.
2. The bamboo laminated construction panel of claim 1 wherein the bamboo starter board layer comprises a plurality of linear bamboo starter boards each having a longitudinal edges disposed with the longitudinal edges adjacent to and adhered to each other, each linear bamboo starter board further comprising two flattened and planed timber bamboo cane halves each having a longitudinal grain, an inner pith surface and a cutaneous outer cortex surface, being laminated together with the inner pith surfaces adjacent and longitudinal grain aligned.
3. The bamboo laminated construction panel of claim 1 wherein the first bamboo starter layer is arranged with the longitudinal grain disposed offset at a preselected angle from the longitudinal vertical centerline of the panel and the second bamboo starter layer is arrange with the longitudinal grain disposed opposingly offset at the same preselected angle from the longitudinal vertical centerline of the panel.
4. The bamboo laminated construction panel of claim 3 wherein the preselected angle is selected from the range of 2 to 12 degrees.
5. The bamboo laminated construction panel of claim 1 wherein at least one linear bamboo starter board layer is interposed between the first linear bamboo starter board layer and the second linear bamboo starter board layer.
6. The bamboo laminated construction panel of claim 1 wherein the wood veneer layer is douglas fir.
