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 technology is complicated, the processing is difficult, and the technical requirements for the workers are high, and one knife can only process one kind of buckle, and when the knife is blunt, the buckle gap becomes larger; this method High requirements on cutting tools, large loss of cutting tools, difficult to control product quality, and low product pass rate
Simultaneously this method processing allowance is big, and bamboo utilization rate is low

Abstract

The invention relates to a manufacturing method of a bamboo laminated material. The method comprises the specific steps of manufacturing locating and overlapping parts, assembling, and laminating, wherein in the step of manufacturing the locating and overlapping parts, the locating and overlapping parts are processed at one end at least in a length direction of each finish planed bamboo strip; in the step of assembling, the finish planed bamboo strips are overlapped sequentially in the length direction to form overlapped areas; the top surfaces of the two adjacent bamboo strips are staggered automatically and mutually after the overlapping; then bamboo strip groups that are lengthened in the length direction after the overlapping are sequentially arranged in a width direction or a height direction to form groups; the overlapped areas are staggered mutually; and in the step of laminating, the bamboo strip groups after the assembling are extruded in the height direction and the width direction till the top surfaces of the two bamboo strips are flush. The method is simple in overlapping course, and high in overlapping efficiency; an overlapping gap is avoided in the step of laminating; the working efficiency of bamboo laminated material manufacturing is improved greatly; and a qualified rate of the bamboo laminated material is increased greatly.

Description

technical field [0001] The invention belongs to the technical field of bamboo laminated wood manufacturing in the wood-based panel industry, and 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 of wood. It h...
