摘要： The invention discloses an infinite-arbitrary-length bamboo chip integrated material. The bamboo chip integrated material is formed by a plurality of lengthened bamboo chips which are glued and overlaid; each lengthened bamboo chip is formed by a plurality of bamboo chip units which sequentially and continuously mesh and are butted; sharp teeth and grooves are formed in the two ends in the length direction of the bamboo chip units, wherein the sharp tooth of each bamboo chip unit and the groove of the corresponding bamboo sheet unit are matched to form a meshing butt-joint part, and the meshing butt-joint parts of the adjacent lengthened bamboo chips are arranged in a staggered mode; and each bamboo chip unit has a thickness of 4-12 mm and a width of 15-50 mm. The invention further provides a manufacturing method of the bamboo chip integrated material, comprising the steps of preparation of the bamboo chip units, meshing and butting, hot pressing and gluing and the like. The present invention has the advantages of small connectors, uniform mechanical strength, and applicability for structures materials such as van truck bottom plates.
