A kind of manufacturing method of bamboo glulam

Abstract

The invention relates to a manufacturing method of bamboo glulam, which specifically includes the steps of end sawing, blank assembly, and pressing, wherein, in the end sawing process, at least one end of the finely planed bamboo strip in the length direction is sawed into a slope, and the slope is used as the blank assembly process The overlapping slopes; the billet assembly process consists of several pieces of finely planed bamboo strips that have been made with lapping slopes along the length direction. The joint part, the top surface of one bamboo strip in the joint part is higher than the bottom surface of the other bamboo strip, forming a dislocation, and then the bamboo strip groups lengthened in the length direction are arranged into groups sequentially along the width or height direction, and the joint part is staggered; The pressing process extrudes the finished bamboo strip group along the height and width directions, so that the finely planed bamboo strips overlapping each other in the length direction slide along the overlapping inclined plane until the dislocation disappears. The method has the advantages of simple processing technology, reduced processing amount and high processing efficiency.

Description

technical field [0001] The invention belongs to the technical field of bamboo laminated wood manufacturing in the wood-based panel industry, and in particular relates to a manufacturing method of bamboo laminated timber. technical background [0002] Bamboo is a low-carbon, environmentally friendly, original ecological and green material recognized by the world for sustainable development (it can be used in 3-6 years), and it is a renewable natural resource. Bamboo can adjust indoor humidity, anti-static, and is beneficial to human health. Especially after deep carbonization, the bamboo furniture processed into bamboo furniture will not change color for a long time, and it can better absorb harmful indoor gases. After the bamboo is thoroughly sterilized by high-temperature cooking, it can fundamentally prevent insects and enzymes from developing. Bamboo has natural color, elasticity, moisture resistance, and high hardness. The growth time of bamboo is only one tenth of that...

Problems solved by technology

[0005] In the traditional manufacturing method of bamboo glulam, in order to achieve the purpose of seamless lengthening, it is generally used to set various buckles at the ends of the finely planed bamboo strips to buckle each other. The disadvantage of this method is: the finely planed bamboo strips The shape of the buckle at the end is complicated, the processing is difficult, and the technical requirements for the workers are high, and a knife can only process one kind of buckle. When the knife is blunt, the buckle gap becomes larger; this method has high requirements for the knife, The tool loss is large, the product quality is difficult to control, and the product qualification rate is low

Simultaneously this method processing allowance is big, and bamboo utilization rate is low
