Embodiment Construction

[0037] A kind of manufacturing method of universal bending glued bamboo laminate

[0038] like Figure 1 to Figure 5 As shown, (1) Bamboo chip sorting, requirements: the section size is stable, there is no obvious defect, and the density difference is small.

[0039] The size and specification of the bamboo slices, the length of the bamboo slices is 2.0m, and the thickness and width series of the bamboo slices are shown in Table 1.

[0040] Table 1 Thickness and width series of bamboo slices

[0041] Bamboo thickness mm 4 5 6 Bamboo width mm 18 20 20

[0042] (2) Fixed-length processing of bamboo slices, in order to make the step staggered seams regularly distributed on the bamboo plywood, the selected bamboo slices need to be fixed-length processing, and the bamboo strips are cut into 2.0 m with a double-end saw for use.

[0043] (3) Bamboo chips are dried. A fast microwave drying oven is used to dry the selected bamboo chips with similar densities...

Abstract

The invention belongs to a manufacturing method for a universal bending glued bamboo laminate board. The manufacturing method comprises the steps of bamboo sheet sorting, bamboo sheet fixed-length processing, bamboo sheet drying, bamboo sheet glue dipping and glue draining, glue dipped bamboo sheet drying, staggered joint assembling, hot press molding, bamboo stringer surface processing, bamboo stringer stress grading, bamboo stringer glue applying, universal bending, nail connecting, marking and packing of bamboo stringer units and the like. By means of the manufacturing method, bamboo engineering materials controllable in length, width, bending degree and performance can be manufactured, the application range of bamboo materials is enlarged through the method, and the manufactured universal bending glued bamboo laminate board is capable of meeting the requirement of the engineering materials, firm, strong, good in tenacity, free of cracks in long-term use and good in quality.

Description

technical field ： [0001] The invention belongs to the technical field of bamboo wood-based panels and bamboo engineering materials. Background technique ： [0002] The development of bamboo wood-based panels has played a very good role in promoting the processing and utilization of my country's rich bamboo resources, and the development and research of various bamboo products have also brought great economic benefits to the society. With the successful application of glued wood, glued bamboo laminates with stable and controllable performance, continuous length, and variable width according to design requirements have been successfully developed. Glued bamboo is also used as a bamboo engineering material in engineering structures. [0003] Engineered wood is an engineered material based on glued wood and structural composite wood. It has standardized performance indicators and various specifications. There are 7 specifications of American engineered wood (glued wood)....
