Problems solved by technology

Due to the small size of the wood core, it is not suitable for processing. It is often discarded as waste or used as firewood. The added value is low, which not only affects the environment but also reduces the utilization rate of wood. It does not meet the requirements of deep processing of wood and environmental protection requirements.
There are also some used for the production of glulam. The glulam produced is made of quadrilateral single-layer glued together. The main problem is: the material utilization rate is low, which can only reach about 45%; the glulam products are mainly boards, and the product specifications Small, severe deformation, narrow application range
The unit structure of hexagonal prisms is insufficient for small-diameter materials, and a large number of edges are cut off, resulting in waste; the unit structure of hexagonal prisms is used, and the contact between adjacent hexagonal prisms is plane-to-plane, which is subject to Relative sliding and dislocation are easy to occur when external force occurs, forming local loose defects, resulting in a decrease in the strength of large glulam

Embodiment 1

[0051] a way, as attached figure 1 As shown, a glulam splicing unit, the splicing unit is a polygonal prism structure, the section of the polygonal prism is polygonal, and the shape is as attached figure 1 As shown, the polygon is a self-mosaic structure.

[0052] In the viewing direction shown in the figure, the polygon itself is symmetrical up and down and left and right.

[0053] A polygon has two parallel sides, side D1E1 and side L1M1 are parallel, and has two sets of zigzag sides, one set of sides M1N1P1A1B1C1D1 is zigzag, one set of sides E1F1G1H1J1K1L1 is zigzag, and the number of zigzag sides in a single set of zigzag is 3 , the lengths of each zigzag side are the same, the length of side M1N1 is the same as that of side P1A1, the length of side A1B1 is the same as that of side C1D1, the sawtooth in the middle part protrudes relative to the sawtooth on both sides, and the sawtooth with the apex A1 in the middle part is relative to the two sides The vertices of the s...

Embodiment 2

[0056] a way, as attached figure 2 As shown, a glulam splicing unit, the splicing unit is a polygonal prism structure, the section of the polygonal prism is polygonal, and the shape is as attached figure 2 As shown, the polygon is a self-mosaic structure.

[0057] In the viewing direction shown in the figure, the polygon itself is symmetrical up and down and left and right.

[0058] A polygon has parallel sides on both sides, side F2G2 is parallel to side U2T2, and has two sets of zigzag sides, one set of sides U2V2W2Y2Z2A2B2C2D2E2F2 is zigzag, one set of sides G2H2J2K2L2M2N2P2R2S2T2 is zigzag, and the number of zigzag sides in a single set of zigzag sides is 5 , the lengths of each zigzag side are the same, the length of side U2V2 is the same as that of side W2Y2 and side Z2A2, the length of side A2B2 is the same as that of side C2D2 and side E2F2, the sawtooth in the middle part protrudes sequentially relative to the sawtooth on both sides, and the apex of the middle part...

Embodiment 3

[0060] Comparing Example 2 with Example 1, it can be found that the sawtooth structure of the polygon can be accumulated sequentially, the number of sawtooth of a single set of sawtooth sides can be accumulated successively, and the number of sawtooth of a single set of sawtooth sides can be 3, 5, or 7 1, 9, 11 or 13….

Abstract

The invention belongs to the field of wood processing, in particular to square stock laminated wood, a processing method thereof and a laminated wood splicing unit. The laminated wood splicing unit ofa polygonal prism structure is processed in a sawing or sawtooth-shaped cutter or milling cutter or mold pressing mode, the cross section of the polygonal prism is a polygon of a self-inlaid structure, and the square stock laminated wood is spliced through the laminated wood splicing unit. The square stock laminated wood is compact and firm in structure and high in strength.

Description

technical field [0001] The invention belongs to the field of wood processing, and in particular relates to a square material glulam, a glulam splicing unit and a processing method thereof. Background technique [0002] With the decrease of natural large-diameter high-quality timber, the proportion of short-period plantation forests in timber resources is increasing, and small-diameter logs from plantation forests will become one of the main timber resources in my country, such as poplar, eucalyptus, pine, willow, Metasequoia, masson pine and other small diameter timber. According to the national timber standard, the diameter of small-diameter logs is 6-16cm, and the length of the inspection ruler is 2-6m. At present, the processing and utilization of small-diameter logs is unreasonable, and the sawn timber yield and utilization rate are low. [0003] At present, there are a large number of processing residues produced in the production process of plywood in my country - the...
