Description
Technical field
The present invention is integrated glued jigsaw of a kind of large format furniture component and preparation method thereof, belongs to small diameter timber allotype unit
The integrated glued jigsaw technical field of part.
Background technology
With the implementation of China's project on protection of natural forest resources, large diameter wood raw material imbalance between supply and demand becomes clear day by day.Manually
Path through the woods grade timber accounting in entire timber resources is increasing.But that there is utilization rates is low for small diameter grade timber, easy to crack
The defects of deformation, mechanical strength are low, and unit size is limited.How to innovate small diameter grade wood utilization method, develop novel saw lumber with
Integrated bonding technique is to solve small diameter grade log efficiently to utilize problem effective way contradictory with timber supply and demand is alleviated.
Currently, making large format square bar using undersized log, plank first is made in undersized log subdivision, passes through broach, gluing etc.
The longitudinal spelling length of process realization, lateral spelling is wide and is laminated spelling thickness, obtains large format jigsaw.Integrated adhesive members can not only retain solid wood
Native texture, while can evade that small dimension wood size is small and the unstable defect of Wood Properties Within.However spelling currently on the market
Plate is largely traditional flat spelling mode, and the plank obtained after being sawed under small dimension wood is much sharp rib flash plate, if treating selvedge list is made
First plate, then flat spelling is carried out, need both sides edging at bevel edge material, hence it is evident that reduce the volume recovery of small dimension wood.Also patent proposes " different
Type unit circuit board ", i.e. jigsaw unit piece cross section are trapezoidal, triangle or diamond shape, and spelling wide mode has directly oblique spell or in list
Element side mortice opening and tenon carry out matching and spell width.It directly tiltedly spells and is easy to occur between adjacent cells part during spelling width
Inconsistent phenomenon is slided, leads to difference in height occur to increase surplus of scraping, increases timber loss.The side of the latter's mortice opening and tenon
Method also wastes material to a certain extent, while processing technology is complicated.
Invention content
Proposed by the present invention is integrated glued jigsaw of a kind of large format furniture component and preparation method thereof, and its object is to solve
Certainly small dimension wood makes the shortcomings of integrated timber utilization rate is low, and processing technology is complicated and furniture component structural behaviour is unstable, provides
A kind of timber utilization rate is higher, processing efficiency higher, structural behaviour the are more stable integrated glued jigsaw of large format furniture component and
Preparation method.
Technical solution of the invention：The integrated glued jigsaw of large format furniture component, is made of three kinds of column material unit pieces,
The column material unit piece includes the right-angled trapezium post material unit piece that cross section is right-angled trapezium, the rhombus column material that cross section is diamond shape
Unit piece and the isosceles trapezoid column material unit piece that cross section is isosceles trapezoid；Each two isosceles trapezoid column material is symmetrical above and below, passes through
Upper bottom surface composes isosceles trapezoid column material unit piece component, and each two right-angled trapezium post material unit piece is symmetrical above and below, right-angle side pair
Together, right-angled trapezium post material unit piece component is composed by upper bottom surface；The both ends of the integrated glued jigsaw of large format furniture component are
The section bevel edge waist length of two groups of right-angled trapezium post material unit piece components, right-angled trapezium post material unit piece is cut with rhombus column material unit piece
The face length of side is identical, integrate jigsaw middle part be rhombus column material unit piece component and isosceles trapezoid column material unit piece, it is two neighboring etc.
Rhombus column material unit piece is inserted between waist trapezoidal column material unit piece component, the rhombus column material unit piece section length of side is cut with isosceles trapezoid
Face waist length is identical；Rhombus column material unit is inserted between right-angled trapezium post material unit piece component and isosceles trapezoid column material unit piece component
Part；Rhombus column material unit piece is fixed with right-angled trapezium post material unit piece, isosceles trapezoid column material unit piece gluing respectively.
Preparation method includes the following steps：
（1）Log screens；
（2）Column material unit piece machine-shaping；
（3）The processing of column material unit piece；
（4）It prepares and integrates jigsaw.
Beneficial effects of the present invention：
1）The practical efficiency and volume recovery higher of small dimension wood, caused by timber loss it is less, under the processing of special-shaped unit piece uses
Sawing mode, optimization processing technology, material use are more efficient；
2）Component is composed by upper and lower trapezoidal column material unit piece upper bottom surface, the form of the embedded rhombus column material unit piece in centre has
Effect restricts the sliding situation that adjacent special-shaped unit piece occurs during jigsaw, avoids caused by the dislocation of single layer abnormal shape unit piece
Planing amount increases, while adjacent cells part bevel edge side is combined without tongue-and-groove, reduces timber loss；
3）Smaller special-shaped jigsaw unit piece releases more internal stress inside log, harmomegathus coefficient smaller, between adjacent panel
Glue area it is larger, integrate it is glued after plate dimensional stability it is more preferable, jigsaw quality higher.
4）The two end face wood grains and color change of entire solid wood jigsaw are more jumped, it appears that and it is more beautiful, it plays
Certain dicoration.
