Description
Technical field
The utility model is a kind of integrated glued jigsaw of large format furniture component, belongs to small diameter timber allotype unit part collection plastic
It is merged plate technique field.
Background technique
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, plate first is made in undersized log subdivision, passes through comb teeth, 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 plate obtained after sawing 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 two 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 wide
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.
Utility model content
The utility model proposes a kind of integrated glued jigsaw of large format furniture component, and its object is to solve small dimension wood
The disadvantages of production integrated timber utilization rate is low, and processing technology is complicated and furniture component structural behaviour is unstable, provides a kind of timber
The integrated glued jigsaw of the large format furniture component that utilization rate is higher, processing efficiency is higher, structural behaviour is more stable.
The technical solution of the utility model：The integrated glued jigsaw of large format furniture component, by three kinds of column material unit pieces
Composition, the column material unit piece includes the right-angled trapezium post material unit piece that cross section is right-angled trapezium, the water chestnut that cross section is diamond shape
Shape column material unit piece and cross section are the isosceles trapezoid column material unit piece of isosceles trapezoid；It is right above and below every two isosceles trapezoid column material
Claim, compose isosceles trapezoid column material unit piece component by upper bottom surface, every two right-angled trapezium post material unit piece is symmetrical above and below, straight
Arm of angle alignment, composes right-angled trapezium post material unit piece component by upper bottom surface；The integrated glued jigsaw of large format furniture component
Both ends are two groups of right-angled trapezium post material unit piece components, section bevel edge waist length and the rhombus column material list of right-angled trapezium post material unit piece
Element cross-section side length is identical, integrate jigsaw middle part be rhombus column material unit piece component and isosceles trapezoid column material unit piece, it is adjacent
Rhombus column material unit piece, rhombus column material unit piece section side length and isosceles are inserted between two isosceles trapezoid column material unit piece components
Waist length in trapezoid cross section is identical；Rhombus column is inserted between right-angled trapezium post material unit piece component and isosceles trapezoid column material unit piece component
Material unit piece；Rhombus column material unit piece is fixed with right-angled trapezium post material unit piece, isosceles trapezoid column material unit piece gluing respectively.
The beneficial effects of the utility model：
1）The practical efficiency and volume recovery of small dimension wood are higher, caused by timber loss it is less, the processing of special-shaped unit piece is adopted
With sawing procedure mode, optimization processing technology, material use is more efficient；
2）Component, the shape of centre insertion rhombus column material unit piece are composed by upper and lower trapezoidal column material unit piece upper bottom surface
Formula, the sliding situation that the adjacent special-shaped unit piece of effective restraint occurs during jigsaw, avoids the dislocation of single layer abnormal shape unit piece
Caused planing amount increases, while adjacent cells part bevel edge side is combined without tongue-and-groove, reduces timber loss；
3）Lesser abnormal shape jigsaw unit piece releases more internal stress inside log, and harmomegathus coefficient is smaller, adjacent panel
Between glue area it is larger, integrate it is glued after plate dimensional stability it is more preferable, jigsaw quality is 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.
