Description
Technical Field
The invention relates to a large-breadth furniture component integrated glued jointed board and a preparation method thereof, belonging to the technical field of small-diameter special-shaped single-element integrated glued jointed boards.
Background
Along with the implementation of natural forest resource protection engineering in China, the contradiction between supply and demand of large-diameter-grade wood raw materials is becoming obvious. The small diameter grade timber in artificial forest has larger and larger proportion in the whole timber resource. However, the small-diameter-grade wood has the defects of low utilization rate, easy cracking and deformation, low mechanical strength, limited unit size and the like. How to innovate the utilization method of the small-diameter log, develop the novel making and integrated gluing technology, is an effective way to solve the difficult problem of high-efficiency utilization of the small-diameter log and to relieve the contradiction between supply and demand of the wood.
At present, small-diameter wood is used for manufacturing large-breadth square timber, the small-diameter wood is firstly split into boards, and longitudinal length splicing, transverse width splicing, lamination thickness splicing and the like are realized through procedures such as comb teeth, gluing and the like, so that the large-breadth jointed board is obtained. The integrated glued component not only can keep the natural texture of the solid wood, but also can avoid the defects of small size of the small-diameter wood and unstable wood property. However, most of jointed boards in the current market are in a traditional flat-jointed mode, and a lot of boards obtained after sawing small-diameter materials are sharp-edged rough edges, if the boards are made into a trimming unit board, then the boards are subjected to flat-jointed, two sides are required to be trimmed into oblique edges, so that the material yield of the small-diameter materials is obviously reduced. There are also patents which propose "special-shaped unit integrated boards", i.e. the cross section of the unit elements of the jointed board is trapezoidal, triangular or rhombic, and the width jointing mode is to directly splice obliquely or to make matching width jointing by making mortises and tenons on the side surfaces of the unit elements. The direct oblique splicing is easy to generate sliding dislocation phenomenon between adjacent single elements in the widening process, so that the height difference is generated, the planing allowance is increased, and the wood loss is increased. The latter method of slotting the dovetail and the tenons also wastes material to some extent, and complicates the machining process.
