Abstract

The invention provides a manufacturing method of a bamboo-wood composite laminated timber and belongs to the technical field of bamboo-wood processing. The manufacturing method comprises the following process steps: (1) preparing raw materials; (2) drying; (3) braiding bamboo bundles; (4) immersing in glue; (5) drying; (6) assembling; (7) prepressing; (8) hot pressing; and (9) ageing. Compared with a traditional process for manufacturing recombined bamboo by adopting a mold pressing manner, mechanization is realized in a manufacturing process of a bamboo bundle single board; the spreading of a plate blank is similar with the spreading of a plywood; and compared with the spreading of a recombined bamboo plate blank, the spreading is relatively simple, and the production efficiency is relatively high. Meanwhile, a traditional recombined bamboo product has the same fiber array direction so that the longitudinal strength of the product is remarkably higher than transverse strength. According to the bamboo-wood composite material manufactured by the manufacturing method, the method is carried out by symmetrically assembling the bamboo bundle single board and a wood single board, so that the difference of the transverse strength and the longitudinal strength of the material is reduced and the transverse strength is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of bamboo and wood processing, and in particular relates to a method for manufacturing bamboo and wood composite laminated timber. Background technique [0002] Recombined bamboo is a product that is currently being developed in the bamboo processing industry. In the manufacturing process, bamboo bundles are mainly used as the structural unit, and the billets are assembled along the grain, and are glued into plates or squares by hot pressing or cold pressing. Its outstanding advantage is the high utilization rate of raw materials, which has completely changed the original properties of bamboo and has excellent mechanical properties. The products can be widely used in indoor and outdoor flooring, furniture, building structural materials and decoration materials, as well as various high-strength material demand fields. [0003] However, the production of recombined bamboo is mainly carried out by artificial ...
