Description
Technical Field
The invention belongs to the field of wood processing, and particularly relates to a square laminated wood, a laminated wood splicing unit and a processing method thereof.
Background
With the increasing decrease of natural large-diameter-grade high-quality wood, the proportion of short-period artificial forests in wood resources is increasing, and small-diameter-grade logs from the artificial forests become one of main wood resources in China, such as small-diameter logs of poplar, eucalyptus, pine, willow, Chinese redwood, Chinese red pine and the like. The national timber standard stipulates that the diameter of a small-diameter log is 6-16cm, and the length of a measuring scale is 2-6 m. The current small-diameter log processing and utilization is unreasonable, and the lumber recovery rate and the utilization rate are low.
At present, China has a large amount of processing residues generated in the production process of plywood, namely wood cores (wood round bars) left after veneer rotary cutting of wood, and felling residues and mountain clearing residues with the diameter of less than 6cm, wherein the diameter of the felling residues is between 2 and 6 cm. Because the wood core is small in size and not suitable for processing, the wood core is often discarded as waste or used as firewood, the added value is low, the environment is influenced, the utilization rate of the wood is reduced, and the requirements of deep processing of the wood and the environmental protection are not met. Some of the laminated wood is also used for producing laminated wood, and the produced laminated wood is formed by gluing quadrangular single layers, and the main problems are that: the material utilization rate is low and can only reach about 45 percent; the laminated wood product mainly uses plates, and has small product specification, serious deformation and narrow application range.
The small-diameter timber and the processing residues can not be restored into the large-diameter timber for re-processing and utilization, and the method becomes a hot point of research.
The patent with publication number "CN 101983851A" discloses a technology for preparing laminated wood from small-diameter logs, which comprises cutting the small-diameter logs to length and lengthening the short wood to length to obtain log sections with standard length, processing the log sections into regular hexagonal prisms or semi-regular hexagonal prisms by a chipping and wood-making combination machine, coating cold-pressing glue on multiple surfaces of the regular hexagonal prisms or on three surfaces of the semi-regular hexagonal prisms, assembling in a certain manner, and cold-pressing with high frequency to obtain the high-performance laminated wood.
The patent with publication number "CN 104210013A" discloses a method for manufacturing a large-section hexagonal prism laminated wood, which comprises the steps of grading the diameter of small-diameter logs, drying, processing the structural units of the laminated wood, fixing the length, gluing, assembling and gluing to form the large-section laminated wood.
The two patent technologies are that small-diameter wood is processed into a hexagonal prism unit structure, and the hexagonal prism is used for gluing, assembling and assembling into a large laminated wood. The small-diameter timber is not fully utilized due to the adoption of a hexagonal prism unit structure, and a large amount of edge skins are cut off to form waste; the unit structure of the hexagonal prisms is adopted, the adjacent hexagonal prisms are in plane-to-plane contact, relative sliding and dislocation are easily generated when external force is applied, the defect of local looseness is formed, and the strength of the large laminated wood is reduced.
