Enough rigidity, ensures global formation effect, and makes product winding thickness excessive, and intensity is superfluous, winding cycle length, the low feelings of efficiency
Condition.Therefore, the structure and its manufacture craft for finding a kind of suitable heavy section product bamboo wound composite product are needed badly, makes it full
Needed for sufficient product while strength and stiffness, global formation effect is good, and thickness is small, and the winding cycle is short, efficiency high.
Utility model content
For the disadvantages described above or Improvement requirement of prior art, it is multiple that the utility model provides a kind of sandwich structure bamboo winding
Laminate article, can be while strength and stiffness needed for product be met, global formation effect is good, and thickness is small, wind the cycle
It is short, efficiency high, bamboo wound composite product is accumulated suitable for heavy section.
To achieve the above object, the utility model proposes a kind of sandwich structure bamboo wound composite product, by it is interior extremely
Outer to include interior enhancement layer, laminboard layer and outer enhancement layer successively, the interior enhancement layer and the outer enhancement layer are by being stained with tree
The thin bamboo strips used for weaving of fat winds the thin bamboo strips used for weaving layer of one or more layers formation, and the laminboard layer is alternately folded by ring bamboo chip layer and axial bamboo chip layer
Add one or more groups of compositions, the ring bamboo chip layer along the sandwich structure bamboo wound composite product by being axially distributed
The spaced ring bamboo chip section composition of multistage, the ring bamboo chip section are to wind one layer or more by being stained with the bamboo chip ring of resin
Layer is formed, and the axial bamboo chip layer is the axial bamboo formed by the bamboo chip positioned axially multirow arranged in parallel for being stained with resin
One or more layers formation of ring arrangement winding on ring bamboo chip layer of piece curtain.
Preferably, the width of the bamboo chip and thickness are all higher than the width and thickness of the thin bamboo strips used for weaving.
In general, by the contemplated above technical scheme of the utility model compared with prior art, mainly possess with
Lower technological merit：
The utility model proposes a kind of sandwich structure bamboo wound composite product, by being designed in thin bamboo strips used for weaving enhancement layer
The laminboard layer that space is made up of spaced ring bamboo chip layer and axial bamboo chip layer is added, makes overall structure strong needed for satisfaction
Rigidity is high while spending, and global formation effect is good, saves bamboo wood, reduces the winding thickness of thin bamboo strips used for weaving enhancement layer, so as to lift production
Efficiency, shorten the production cycle.In addition, also improve sqouynd absorption lowering noise function.
Brief description of the drawings
Fig. 1 is sandwich structure bamboo wound composite article construction schematic diagram of the present utility model.
Wherein：1- interior enhancement layers, 2- laminboard layers, 21- ring bamboo chip layers, 211- ring bamboo chip sections, 22- axial directions bamboo chip layer,
3- outer enhancement layers.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.In addition, institute in each embodiment of the utility model disclosed below
As long as the technical characteristic being related to does not form conflict each other, can is mutually combined.
A kind of sandwich structure bamboo wound composite product of the present utility model, as shown in figure 1, including successively from the inside to the outside
Interior enhancement layer 1, laminboard layer 2 and outer enhancement layer 3, the interior enhancement layer 1 and the outer enhancement layer 3 are the bamboos by being stained with resin
The thin bamboo strip winds the thin bamboo strips used for weaving layer of one or more layers formation, and concrete operations are as follows：Raw bamboo is cutd open into growth 2-6m, thick 0.5-1.5mm, wide 1-
10mm thin bamboo strips used for weaving, is made sequential like（For example, the parallel close-packed arrays of thin bamboo strips used for weaving can be embarked on journey, along longitudinal arrangement multirow, sutured
Into continuously long thin bamboo strips used for weaving band）, rolled, which is mounted on wrapping machine, starts winding work, and thin bamboo strips used for weaving spiral cross winding or ring arrangement twine
It is wound on core, sprinkling is prepared according to proportioning while winding amino resins, filler, the mixed amino resin adhesive of curing agent
Glutinous agent, winds one or more layers.The laminboard layer 2 is by ring bamboo chip layer 21 and alternately one group or more of the superposition of axial bamboo chip layer 22
Group composition, the ring bamboo chip layer 21 are between being had by the multistage being axially distributed along the sandwich structure bamboo wound composite product
Every ring bamboo chip section 211 form, the ring bamboo chip section 211 is to wind one or more layers by the bamboo chip ring for being stained with resin
Formed, the axial bamboo chip layer 22 is the axial bamboo formed by the bamboo chip positioned axially multirow arranged in parallel for being stained with resin
Piece curtain ring on ring bamboo chip layer 21 winds one or more layers formation.Concrete operations are as follows：Raw bamboo is cutd open into bamboo chip, bamboo chip
Rigidity is compared with thin bamboo strips used for weaving height, it is preferable that the width and thickness of bamboo chip are all higher than the width and thickness of the thin bamboo strips used for weaving, and the size of bamboo chip is length
3-7m, thick 2-5mm, wide 10-30mm, the ring bamboo chip band of sequential like and axial bamboo sheet curtain, the length side of ring bamboo chip band is made
It is that multirow is arranged by bamboo chip along its length to the length direction for bamboo chip, along its width arrangement 1-3 row, passes through seam
Continuous long bamboo chip band made of system, bonding etc.；The length direction of axial bamboo sheet curtain be bamboo chip width, be by bamboo chip along its
Width multirow arranged in parallel, pass through continuous long bamboo sheet curtain made of sewing, be bonded etc..Ring bamboo chip band rolled is mounted in
Start winding work on wrapping machine, ring bamboo chip band ring is wrapped in interior enhancement layer 1, and sprinkling is matched somebody with somebody according to proportioning while winding
The mixed amino resins gluing agent of amino resins, filler, curing agent of system, wind one or more layers and form ring bamboo chip section
