The process steps include 1: Using radial bamboo slivers with a thickness of 1.0 to 3.0 mm, a width of 3.0 to 5.0 mm, and a length of 70.0 to 130.0 cm as constituent units to be pressed into laminated bamboo sliver lumber; 2: The flattened bamboo strip with thickness of 3.05.0mm, width of 12.020.0mm, and length of 70.0-130.cm is used as the constituent unit to be pressed into bamboo plywood; 3: The laminated bamboo sliver lumber and bamboo plywood are double-side sanded, the length and width are extended to enlarge the strips size; 4: The laminated bamboo strip lumber and bamboo plywood after lengthening and widening are vertically cross assembled with cold pressing adhesive to produce vertical cross laminated bamboo structural timber. The method for manufacturing vertical cross laminated bamboo structural materials provided by the present invention, has the characteristics of as follows: it is of high raw material utilization rate and large size, and the prepared plates have excellent mechanical properties, good dimensional stability, and its strength performance can meet the use requirements of wooden structural members. It can be processed into a variety of high-strength wall panels and carriage floor panels. It is a new type of large-size structural material.
